Abstract

Dynamic grants (DG) for retransmission by a user equipment (UE) use the communication resource more efficiently while configured grants (CG) for retransmission by the UE reduce overhead and latency. A base station (BS) uses radio resource control signaling to configure the UE with a retransmission timer or without a retransmission timer. The BS transmits to the UE a set of CG configurations configuring a set of configured grant uplink (CG-UL) processes. The set of CG configurations includes information indicating whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. The BS is also configured to receive communication on UL from the UE. The communication from the UE is received based on the set of CG-UL processes and the indication whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. A UE may have different channel conditions for a plurality of CG-UL processes of the UE and therefore using a combination of CG based retransmission and DG based retransmission will reduce latency and reduce overhead and use the resource more efficiently.

ORTHOGONAL TIME FREQUENCY SPACE PRECODING FOR TRACKING REFERENCE SIGNAL (17658411)

Inventor Raviteja PATCHAVA

Brief explanation

The abstract describes a wireless communication technique called orthogonal time frequency space (OTFS) precoding. In this technique, a first network node applies OTFS precoding to a set of tracking reference signal (TRS) resource samples that are allocated in a delay-Doppler domain. This results in a set of TRS symbols with the OTFS precoding. The first network node then transmits these TRS symbols to a second network node. The important feature of this transmission is that the TRS symbols have a uniform spacing in the time domain. The abstract mentions that there are numerous other aspects described in the disclosure, but does not provide any further details about them.

BLIND COMMON PHASE ERROR AND RESIDUAL CARRIER FREQUENCY OFFSET MITIGATION (17717682)

Inventor Michael Levitsky

Brief explanation

The abstract describes methods, systems, and devices for wireless communications that support blind common phase error (CPE) and residual carrier frequency offset mitigation. These techniques aim to mitigate CPE at a receiving device without the need for a phase tracking reference signal (PTRS), which reduces overhead and improves performance. The receiving device can receive a shared channel message in a scheduled shared channel allocation without a PTRS allocation, relying on its capability to apply blind CPE mitigation. Blind CPE mitigation for subsequent data symbols of the shared channel message can be based on the blind CPE estimation for the previous symbol, allowing for robust mitigation of a residual carrier frequency offset.

Abstract

Methods, systems, and devices for wireless communications are described. The described techniques support blind common phase error (CPE) and residual carrier frequency offset mitigation. Generally, the described techniques provide for blind CPE mitigation at a receiving device without a phase tracking reference signal (PTRS) associated with less overhead and improved performance as compared to use of a PTRS to mitigate CPE. A receiving device may receive a shared channel message in a scheduled shared channel allocation in accordance with a PTRS configuration that omits a PTRS allocation based on a capability of the receiving device to apply blind CPE mitigation for shared channel receptions. In some examples, with a single DMRS symbol allocation, blind CPE mitigation for each subsequent data symbol of a shared channel message may be based on the blind CPE estimation for the previous symbol, which may enable robust mitigation of a residual carrier frequency offset.

Inventor Yavuz Yapici

Brief explanation

This abstract describes methods, systems, and devices for wireless communications. It introduces a technique that allows a receiving device to skip or simplify the equalization process by using a reconfigurable intelligent surface (RIS) to perform multipath fading equalization. The transmitting device selects a RIS that is close enough to the receiving device to ensure that the multipath fading between the RIS and the receiver is below a certain threshold. The selected RIS is then configured with a phase matrix to compensate for the multipath fading over the wireless link between the transmitting device and the RIS. As a result, the receiving device can omit or perform a simpler equalization procedure compared to a scenario where the RIS is not used for multipath fading compensation.

TRANSMIT PRECODING FOR PEAK TO AVERAGE POWER RATIO REDUCTION (17718950)

Inventor Noam ZACH

Brief explanation

The abstract describes a method to improve the efficiency of a power amplifier in a wireless communication system. The method involves reducing the peak to average power ratio (PAPR) by using a technique called PAPR reduction precoding. This technique modifies the received signal without affecting its performance, resulting in a lower overall transmit PAPR. 

To implement this technique, the transmitting device first constructs a frequency domain (FD) response for the PAPR reduction precoding. It then estimates the channel between itself and one or more receiving devices. The PAPR reduction precoding is applied to the estimated channel.

Next, the transmitting device constructs a multiple input multiple output (MIMO) precoding matrix, taking into account the FD response of the PAPR reduction precoding. This matrix, along with the PAPR reduction precoding, is applied to the FD signal.

On the receiving end, the receiving device applies the conjugate of the FD response to the received FD signal from the transmitting device. It then processes at least a received reference signal based on the PAPR reduction precoder.

Overall, this method aims to reduce the PAPR in wireless communication systems, leading to improved power amplifier efficiency.

Abstract

In a wireless communication system, a peak to average power ratio (PAPR) may affect the efficiency of a power amplifier. To reduce a PAPR, a transmitting device may utilize a PAPR reduction precoding that changes a received signal without performance impact so the overall transmit PAPR is reduced. The transmitting device constructs a frequency domain (FD) response to the PAPR reduction precoding, estimates a channel to one or more receiving devices, and applies the PAPR reduction precoding to the estimated channel. The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.

This abstract describes a method for generating channel state reports in a wireless communication system. A base station sends a reference signal over multiple ports, and a user equipment (UE) receives the signal and measures its amplitudes on each port.

Inventor Ozcan OZTURK

Brief explanation

This abstract discusses the optimization of paging operations in relay systems. It explains that a remote user equipment (UE) can provide paging identifiers to relay UEs over relay links. These relay UEs then pass on the paging identifiers to a serving radio access network (RAN) node, which in turn shares them with an anchor RAN node and/or core network node. This helps optimize the paging process for the remote UE by limiting it to the cells that include the relay UEs. The abstract also mentions that the remote UE can choose to receive the paging message from one relay UE or from all of them. Additionally, a relay UE has the ability to reject a paging message by transmitting a page reject message.

Brief explanation

This disclosure presents methods, devices, and systems for enabling simultaneous two-way communication in wireless networks. It introduces the concept of multiple bandwidth parts (BWPs) that can be active at the same time for communication between a user equipment (UE) and a base station. These BWPs can be used for either downlink (DL) or uplink (UL) communication. One BWP operates in a half-duplex (HD) slot, while another BWP operates in an adjacent full-duplex (FD) slot. The UE can also change the status of active BWPs after a certain period of time, such as deactivating them, switching to a default BWP, or changing the assigned role of the BWP.

SLOT POSITION OFFSETS ASSOCIATED WITH A DOWNLINK CONTROL INFORMATION IN A PHYSICAL DOWNLINK SHARED CHANNEL (18335871)

Inventor Zhifei FAN

Brief explanation

The abstract describes a method used by a base station (BS) to transmit control information to a user equipment (UE). The control information is divided into two parts: the PDCCH (Physical Downlink Control Channel) and the PDSCH (Physical Downlink Shared Channel). The PDCCH contains the first part of the control information, while the PDSCH contains the second part (referred to as a 2-part DCI).

In this method, the first grant associated with the second part of the control information is offset from the slot position of the second part. Similarly, the second grant associated with the second part is offset from the slot position to which the first grant is offset. This offsetting helps in efficiently transmitting the control information.

Additionally, the method involves grouping two or more grants together, and mapping each group to a PUCCH (Physical Uplink Control Channel). This grouping and mapping process further enhances the transmission of control information.

Overall, this method improves the efficiency and reliability of transmitting control information from the BS to the UE.

Abstract

In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Inventor Syam Pavan Vadapalli

Brief explanation

The abstract describes methods, systems, and devices for wireless communications. It explains that a user equipment (UE) can be configured with multiple bandwidth parts (BWPs) and support multiple subscriber identification modules (SIMs) in a multi-SIM (MSIM) mode. The UE may temporarily switch away from its default data SIM subscription, resulting in a missed downlink signaling for a certain period. To avoid latency caused by this missed signaling, the UE can autonomously switch to a different BWP without waiting for a command from the network. This can be achieved by transmitting a scheduling request (SR) on each of the multiple BWPs and monitoring the BWPs for any signaling in response to the SR.

Abstract

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may be configured with multiple bandwidth parts (BWPs) and may support multiple subscriber identification modules (SIMs) (e.g., may operate in a multi-SIM (MSIM) mode). The UE may tune away from a default data SIM (DDS) subscription for a tune away gap and may miss any downlink signaling, such as an indication of a BWP switch, for a duration of the tune away. To avoid latency resulting from such missed downlink signaling, the UE may support a mechanism according to which the UE may autonomously switch to a different BWP despite a missed command from a network entity. Such a mechanism may include transmission of a scheduling request (SR) on each of multiple BWPs configured for the UE and monitoring each of the multiple BWPs for signaling responsive to the SR.
