Abstract: Wireless communications systems and methods related to dynamically configuring sounding reference signal (SRS) resources are provided. In some aspects, a base station may measure a SRS transmission transmitted by a user equipment (UE) and receive, using a receive beam selected based on the measuring, a transmission from the UE. In some aspects, a UE may transmit a SRS transmission; and receive, from the BS, a downlink control information (DCI) message including a SRS resource indicator (SRI) for use by the UE in selecting a beam to transmit to the BS. The SRS transmission may be transmitted using a SRS resource and may have a SRS parameter that is indicated in or related to a triggering message, or related to a transmission parameter of a communication between the BS and the UE.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a single dynamic signaling communication, an indication to activate one or more coverage enhancement parameters. The UE may activate the one or more coverage enhancement parameters based at least in part on receiving the indication. Numerous other aspects are provided.

Abstract: A method of wireless communication by a UE (user equipment) includes receiving group-common downlink control information (DCI) indicating coverage-enhancements including channel state information (CSI) report settings for a group of UEs and/or PDCCH repetition. The method also includes reporting CSI in accordance with the coverage-enhanced CSI report settings, which may include report repetition. A method of wireless communication by a base station includes transmitting group-common downlink control information (DCI) indicating coverage-enhanced channel state information (CSI) report settings and/or PDCCH repetition for a group of UEs. The method also includes receiving CSI reports from the group of UEs in accordance with the group-common DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit, to a receiving device, an identification of a subset of code block groups (CBGs) of a set of CBGs, wherein the set of CBGs comprises a transport block; and transmit, to the receiving device, an initial data transmission comprising the subset of CBGs. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to wireless communications systems including the use of a joint grant generated in and transmitted by a base station to a user equipment (UE) over a first communication link for establishing a sidelink (SL) with a relay UE. The joint grant provides a first resource assignment for establishing the SL between the UE and relay UE, as well as a second resource assignment that is transmitted to the relay UE for establishing an uplink from the relay UE to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical broadcast channel (PBCH) communication from a base station (BS). The UE may identify, based at least in part on a determination that the PBCH communication indicates a reference signal that is to be transmitted prior to transmission of a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) communication, one or more radio resources in which the reference signal is to be transmitted. The UE may monitor for the reference signal, from the BS, in the one or more radio resources prior to reception of the RMSI PDCCH communication. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for efficiently transmitting data over multiple radio access technologies (RATs), for example, between a base station and a user equipment (UE). An example method by a receiver device generally includes receiving network coded packets from multiple transmitter devices, decoding the network coded packets, based on a network coding decoding scheme, to recover one or more source packets, generating feedback based on the decoding, and transmitting the feedback to the multiple transmitter devices.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for beam refinement via physical random access channel (PRACH) repetition. A method that may be performed by a network entity includes determining resources to monitor for a PRACH transmission sent from a user equipment (UE) as part of a random access channel (RACH) procedure, performing receive beam sweeping when receiving PRACH repetitions sent using the determined resources, using results of the receive beam sweeping to refine one or more beams and to select a refined beam of the refined one or more beams, and using the selected refined beam for at least one of receiving a subsequent message from the UE as part of the RACH procedure or sending a subsequent message to the UE as part of the RACH procedure.
