UPLINK CONTROL INFORMATION MAPPING FOR UPLINK TRANSMISSION SWITCHING (18245710)

Main Inventor

Yiqing CAO

Brief explanation

This abstract describes methods, systems, and devices for wireless communications. It explains that a user equipment (UE) can perform dual uplink transmissions on two different operating bands of a carrier aggregation configuration. The UE can communicate on a primary cell and a secondary cell, each associated with different component carriers. The UE generates uplink control information (UCI) for the secondary cell, which is normally mapped to an uplink shared transmission of the primary cell. However, if the UE identifies that uplink transmission switching is going to occur before transmitting the UCI, it will modify the cell mapping for the UCI transmission based on this identified switching.

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to perform dual uplink transmissions on two different operating bands of a carrier aggregation configuration. The UE may communicate on a primary cell associated with a primary component carrier and a secondary cell associated with a secondary component carrier. The UE may generate uplink control information (UCI) for the secondary cell, which is mapped to an uplink shared transmission of the primary cell. In some cases, however, the UE may identify that uplink transmission switching is to occur prior to the transmission of the UCI, such that UE may not map the UCI to the uplink shared transmission of the primary cell. Accordingly, the UE may modify a cell mapping for the transmission of the UCI based on the identified uplink transmission switching.

Main Inventor

Muhammad Sayed Khairy ABDELGHAFFAR

Brief explanation

This abstract describes techniques and apparatus for determining the configuration of a transport block (TB) and the acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) user equipment (UE). One technique involves receiving channel state information (CSI) reports from the FD UE and using this information to determine the TB configuration or feedback type for a communication slot, which can include both half duplex (HD) symbols and FD symbols. The determined configuration or type is then signaled to the UE. Another technique involves receiving downlink data transmissions from a base station (BS) across slots and determining the duplexing mode associated with each slot. The downlink data transmissions are then acknowledged based on the determined duplexing mode.

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support feedback-related signaling designs that support a feedback mechanism for uplink data transmissions that use or include multiple transport blocks (TBs). The UE may transmit a data message including multiple TBs and a feedback process identifier (ID) corresponding to the data message may be associated with the multiple TBs. If the data message is a configured grant (CG) physical uplink shared channel (PUSCH) transmission, the UE may multiplex uplink control information (UCI) with the data message that indicates feedback-related information for each of the multiple TBs. The network entity may attempt to decode the data message including the multiple TBs and may generate downlink feedback information (DFI) based on whether the network entity successfully decodes one or more of the multiple TBs.

PRIORITIZATION RULES FOR UPLINK AND DOWNLINK CHANNELS IN FULL-DUPLEX SYSTEMS (17730970)

Main Inventor

Qian Zhang

Brief explanation

This abstract describes methods, systems, and devices for wireless communications. It explains how a user equipment (UE) operating in a half-duplex mode can be scheduled by a network entity operating in a full-duplex mode. The UE is scheduled to receive a downlink communication and transmit an uplink communication during the same symbol period, with both uplink and downlink channel multiplexing enabled. The UE then communicates with the network entity during this symbol period based on a prioritization rule associated with the half-duplex mode. This prioritization rule determines whether the UE should receive the downlink communication or transmit the uplink communication when both are scheduled in the same symbol period and when uplink and downlink channel multiplexing is enabled.

Main Inventor

Ambarish TRIPATHI

Brief explanation

The abstract describes a method for a user equipment (UE) to select and transmit a RACH message to a network node. The UE obtains information about a subset of PRACH resources that meet a certain threshold value. It then selects a specific PRACH resource based on its channel metrics or associated parameters. The UE evaluates multiple qualifying SSBs/CSI-RSs and selects one based on scheduling opportunities and power usage.

Abstract

A UE may obtain an indication of a first subset of PRACH resources in a set of PRACH resources, the first subset of PRACH resources having a set of channel metrics that is greater than or equal to a first threshold value, select a first PRACH resource from the first subset of PRACH resources based on a first set of channel metrics of the first PRACH resource or a first RO associated with the first PRACH resource, and transmit a RACH message to a network node in the first RO. The UE may evaluate the multiple qualifying SSBs/CSI-RSs and select one SSB/CSI-RS among the qualifying SSBs/CSI-RSs based on a scheduling opportunity of the associated ROs and a power usage on the UE side.

CLOSED LOOP TIME AND FREQUENCY CORRECTIONS IN NON-TERRESTRIAL NETWORKS (17733636)

Main Inventor

Ayan Sengupta

Brief explanation

This abstract describes methods, systems, and devices for wireless communications. It explains techniques for reducing errors in time or frequency adjustments for preambles of a random access procedure. In this process, a user equipment (UE) may use a specific adjustment value when transmitting data to a non-terrestrial network. However, when transmitting the preamble of a random access procedure, the UE adjusts the timing or frequency based on indications received from the network, rather than resetting the adjustment to zero. This approach helps maintain or improve the reception performance of the preamble, requiring fewer position measurements for the UE or non-terrestrial network entity.

Abstract

Methods, systems, and devices for wireless communications are described. Described techniques provide for mitigating error in time or frequency adjustments for preambles of a random access procedure. A user equipment may use one value for the adjustment when transmitting data to a non-terrestrial network, but then transmit the preamble of a random access procedure according to a preamble-specific time or frequency adjustment based on one or more indications received from the network (e.g., rather than resetting the adjustment to “0”). By using some signaled value for the preamble-specific timing or frequency adjustment rather than resetting the adjustment to “0,” preamble reception performance may be maintained or improved with as many or fewer position measurements for the UE or non-terrestrial network entity.

Brief explanation

The abstract describes techniques and devices for using keep-alive signaling to save energy in a network when it is not in use. This involves transmitting a keep-alive signal (KAS) to reduce energy consumption. The KAS can be a smaller version of a synchronization signal block (SSB) that is sent more often than the full SSB. It can also have a different beam sweeping pattern and beam width compared to the full SSB.

Abstract

Aspects of the disclosure provide techniques and apparatuses for using keep-alive signaling for network energy saving in an idle mode. A network entity can transmit a keep-alive signal (KAS) to reduce the energy consumption of a network when the network is in an idle mode. In some aspects, the KAS can be a reduced synchronization signal block (SSB) that is sent more frequently than a full SSB. In some aspects, the KAS can have a different beam sweeping pattern and/or beam width from the full SSB.

DRX ADAPTATION FOR POWER SAVING AND LATENCY REDUCTION (17733986)

Main Inventor

Huilin XU

Brief explanation

This abstract describes a system and method for discontinuous reception (DRX) adaptation in a wireless communication system. In this system, a network entity can configure a user equipment (UE) with a long DRX cycle, which means that the UE will periodically enter a sleep mode to conserve power. However, under certain conditions, the network entity can activate additional short DRX cycles to allow data transfer before the next scheduled sleep period. The abstract also mentions that there are multiple ways to communicate the parameters for the short DRX cycles to the UE, either explicitly or implicitly. These parameters can be included in downlink control information or indicated by bits in a Medium Access Control command received by the UE during the long DRX active time.
