  • Patent number: 11968698
    Abstract: Methods, systems, and devices for wireless communications are described in which control resources may be identified, and a data transmission may be rate-matched around the one or more control channels of multiple UEs or at multiple aggregation levels in the control resources. A user equipment (UE) may identify a search space for a first control channel, and the rate-matching of the data transmission may be performed based on a location of the search space in the control resources. In some cases, a base station may provide a mapping of resources (e.g., a bitmap) within the control resources that are occupied, which may be used for rate-matching.

  • Patent number: 11963172
    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication, including techniques for sidelink resource allocation and communication. In some aspects, a user equipment (UE) may receive from a base station a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE. The UE may transmit the information to the second UE in the first transmission opportunity.

  • Patent number: 11963028
    Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

  • Patent number: 11956847
    Abstract: Methods, systems, and devices for wireless communication are described related to timer-based sidelink discontinuous reception (DRX). A UE may receive configuration information for a sidelink DRX mode from a base station or another UE, which may indicate one or more parameters of the sidelink DRX mode. When operating in the sidelink DRX mode, a group of UEs may have shared active durations and inactive durations for coordinating sidelink communications. In a timer-based sidelink DRX mode, if a UE receives or transmits a sidelink communication, the UE may initiate an inactivity timer, and the UE may continue to monitor a sidelink channel for other sidelink communications while the timer is running. One or more rules may govern the operation of an inactivity timer with respect to the shared inactive durations.

  • Patent number: 11956786
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify uplink (UL) control information (UCI) to transmit during a subframe. The UE may then select a UL channel on which to transmit the UCI based on whether a shared data and control UL channel employs contention-based scheduling. For example, multiple UEs could contend for access to the same semi-persistently scheduled (SPS) physical UL shared channel (PUSCH). Each UE may utilize a different demodulation reference (DMRS) signal cyclic shift to identify their transmissions. In some cases, some UCI, such as channel state information (CSI), may be transmitted on a contention-based PUSCH, while other UCI, such as acknowledgement information, may be transmitted on a physical uplink control channel (PUCCH). In some cases, the channel selection may be based on a configuration received from a base station.
