ASSISTANCE SIGNALING FOR RADIO LINK CONTROL RETRANSMISSIONS (17997652)

Inventor Liangming WU

Brief explanation Methods, systems, and devices for wireless communication are described in this abstract. The techniques involve sending an indication from an upper layer to a lower layer at a transmitting device. This indication helps the lower layer determine whether a packet should be transmitted as an initial transmission or as a retransmission. Based on this determination, the lower layer then decides on a transmission process for sending the packet. The transmitting device then transmits the packet according to the chosen transmission process. By allowing the lower layer to identify the type of transmission needed, it can adjust the transmission process to increase the likelihood of the packet being received by a receiving device or to reduce unnecessary overhead.

Abstract

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for sending, from an upper layer at a transmitting device to a lower layer at the transmitting device, an indication by which the lower layer determines that a packet is to be transmitted as either an initial transmission or as a retransmission. The lower layer at the transmitting device may then determine a transmission process for transmitting the packet based on the indication, and the transmitting device may transmit the packet in accordance with the transmission process. Because the lower layer may identify whether the packet is to be transmitted as either the initial transmission or the retransmission, the lower layer may adapt the transmission process to improve the chances that the packet is received by a receiving device or to limit overhead.

ADAPTIVE LOOP FILTER WITH SAMPLES BEFORE DEBLOCKING FILTER AND SAMPLES BEFORE SAMPLE ADAPTIVE OFFSETS (18181359)

Inventor Nan Hu

Brief explanation Decoding video data involves several steps to improve the quality of the reconstructed video. This device performs these steps by first determining a pre-filtered reconstructed block of video data. Then, it applies either a deblocking filter or a sample adaptive offset filter (or both) to this pre-filtered block, resulting in a filtered reconstructed block.

To further enhance the quality, an adaptive loop filter (ALF) is applied to the filtered reconstructed block. To do this, the device calculates a difference value by comparing the current sample value of the filtered reconstructed block with the value of a neighboring sample from the pre-filtered block. A filter is then applied to this difference value, resulting in a sample modification value.

Finally, the device determines the final value of the filtered sample by using the sample modification value. This process helps in improving the overall quality of the reconstructed video by reducing artifacts and enhancing details.

METHODS AND APPARATUS FOR RECEIVE ANTENNA ADAPTATION FOR USER EQUIPMENT POWER SAVING (18005930)

Inventor Weimin DUAN

Brief explanation The abstract describes a system where a user device (UE) uses special signals called downlink positioning reference signals (PRS) beams to determine its position. These PRS beams are transmitted in a specific way called beamforming, where the signals are focused in a particular direction. The UE receives assistance data that provides information about the configuration of these PRS beams, such as their angles and width. This information helps the UE in selecting or adjusting its receive antennas to optimize power consumption. For example, if the PRS beams are wide, the UE can use fewer antennas to receive them, saving power. On the other hand, if the PRS beams are narrow, the UE can use more antennas to improve reception.

The UE may identify a sensing resource of the set of sensing resources on which a sensing signal is received, and determine one or more of the set of cross-link interference measurement resources that overlap with the sensing resource. The UE may thereby measure the one or more cross-link interference measurement resources for cross-link interference based on the one or more cross-link interference measurement resources overlapping with the sensing resource.

ACTIVE TIME EXTENSION FOR BEAM FAILURE DETECTION (17655201)

Inventor Shanyu ZHOU

Brief explanation The abstract describes a wireless communication system where a user equipment (UE) can receive beam failure detection (BFD) reference signals (RSs) even during periods of discontinuous reception (DRX). The UE can monitor these BFD-RSs in an extended active time outside of the DRX active time. This allows the UE to detect beam failures and improve communication reliability. The abstract mentions that there are other aspects of the disclosure that are described but does not provide specific details about them.

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more beam failure detection (BFD) reference signals (RSs) during an active time under discontinuous reception (DRX). The UE may monitor BFD-RSs in an active time extension that is outside the active time for DRX. The UE may receive one or more BFD-RSs during the active time extension. Numerous other aspects are described.

TECHNIQUES FOR CONFIGURING SEARCH SPACES IN MULTICAST/BROADCAST SERVICE (MBS) WIRELESS COMMUNICATIONS (18189103)

Inventor Le LIU

Brief explanation The abstract describes a method for indicating search spaces and control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). The method involves a device receiving a configuration that defines search spaces for detecting communications intended for a group of user equipment (UEs). The device then determines a priority for detecting control information transmitted over a control channel based on the search spaces. Based on this priority, the device performs detection for the control information over the control channel using the defined search spaces and/or other search spaces.

Abstract

Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

CONTROL MECHANISMS FOR UPLINK CHANNEL ACCESS TYPES (18166395)

Inventor Jing Sun

Brief explanation In this abstract, the focus is on methods, systems, and devices for wireless communications. It describes a control mechanism where a user equipment (UE) and a network entity work together to determine if an upgrade from one channel access type to another is available for an uplink transmission from the UE to the network entity. The network entity configures the UE with a set of channel access types, and the UE determines if the second channel access type is present in the set. If it is, the UE can upgrade from the first channel access type to the second channel access type.

Abstract

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support a control mechanism according to which the UE determines whether an upgrade from a first channel access type to a second channel access type is available for an uplink transmission from the UE to the network entity. For example, the network entity may configure the UE with a set of channel access types and the UE may determine whether the second channel access type is available for the uplink transmission based on which channel access types are present in the set of channel access types. As such, the UE may upgrade from the first channel access type to the second channel access type if the second channel access type is present in the set of channel access types.

DATA TRANSMISSION IN RACH PROCEDURES (18009253)

Inventor Ruiming ZHENG

Brief explanation Methods and devices for wireless communication are disclosed in this document. The apparatus, which can be a user equipment (UE) or a base station, is able to determine whether to enter a two-step RACH (Random Access Channel) procedure while in an RRC (Radio Resource Control) inactive state. If it decides to proceed with the two-step RACH procedure, the apparatus can transmit uplink data within a payload of a message A (MsgA). This payload contains at least the uplink data. The apparatus then monitors for a message B (MsgB) as part of the two-step RACH procedure. Once the MsgB is received, it includes a fallback indication that contains a fallback RAR (Random Access Response). In response to receiving the MsgB, the apparatus retransmits the payload of the MsgA.

The apparatus can also transmit the MsgA of the two-step RACH procedure, the MsgA including the payload, the payload including at least the uplink data. Additionally, the apparatus can monitor for a MsgB of the two-step RACH procedure. The apparatus can also receive the MsgB of the two-step RACH procedure, where the MsgB includes a fallback indication including a fallback RAR. Further, the apparatus can retransmit the payload of the MsgA when the MsgB including the fallback indication is received.

RRC CONFIGURATION FOR SINGLE LINK, DUAL SUBSCRIBER IDENTITY MODULE DUAL ACTIVE (DSDA) (18005925)

Inventor Punyaslok PURKAYASTHA

Brief explanation The abstract describes a Single-Link DSDA (Dual SIM Dual Active) apparatus. It explains that the apparatus allows for the reconfiguration of RRC (Radio Resource Control) connections associated with two SIM cards. One SIM card is provided with its own RRC configuration, while the other SIM card uses a common configuration for its RRC connection. The abstract also mentions the establishment of a primary SIM card that can only perform certain tasks. Additionally, it states that the RRC connection establishment and release for a dual-SIM device can be done by using the primary connection to send a common configuration and utilizing both connections for different configurations.

NETWORK SOLUTION FOR HANDLING MISSED UPLINK GRANTS (17587917)

Inventor Dominique Francois Bressanelli

Brief explanation

Abstract

Methods, systems, and devices for wireless communications are described. A base station may transmit a first transport block including a first uplink grant which schedules a first set of uplink shared channel transmissions for the UE. The base station may monitor the channel to detect an energy value for a demodulation reference signal (DMRS) associated with the one or more uplink shared channel transmissions associated with the first uplink grant that is less than a threshold energy value. Based on the relatively low DMRS energy, the base station may modify a size of a second transport block relative to the first transport block, the second transport block including a second uplink grant that schedules a second set of one or more uplink shared channel transmissions for the UE. The base station may then signal the grant for the modified second transport block to the UE or to another device.
