Abstract: Method and apparatus to use different GI sequences for different FDM UEs. The apparatus calculates a GI of each UE from a set of UEs based at least on a delay spread associated with each UE from the set of UEs. The apparatus multiplexes data and the GI of each respective UE from the set of UEs to generate a waveform. The apparatus transmits the waveform to the set of UEs. The apparatus may receive, from each UE from the set of UEs, the delay spread associated with each UE from the set of UEs. The apparatus may multiplex the GI of each respective UE from the set of UEs prior to performing a DFT operation on the GI and the data. The apparatus may multiplex the GI of each respective UE from the set of UEs after performing an IDFT operation to generate the waveform.

Abstract: Certain aspects of the present disclosure provide techniques for including physical layer RSSI in CSI reporting. In some cases, a method for wireless communications by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration that specifies physical layer received signal strength indicator (RSSI) measurement as a report quantity, performing physical layer RSSI measurement, and reporting the RSSI to a network entity in accordance with the CSI reporting configuration.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a base station and/or UE. The apparatus can calculate a number of coded bits based on a number of downlink control information (DCI) information bits. The apparatus can also determine an amount of one or more code blocks (CBs) in DCI based on at least one of the number of coded bits or the number of DCI information bits, each of the one or more CBs including a plurality of the coded bits. Moreover, the apparatus can transmit a physical downlink shared channel (PDSCH) including the DCI, wherein the DCI includes at least one of the one or more CBs or one or more coded blocks. The apparatus can also encode the one or more CBs in the DCI based on the determined amount of one or more CBs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.

Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.

Abstract: Apparatus and method to allow for the activation of SPS/G with multi-PDSCH/PUSCH. The apparatus receives DCI comprising a TDRA assignment that is configured with multiple PUSCHs or multiple PDSCHs. The apparatus selects a first SLIV of a TDRA row indicated by the TDRA assignment comprising one or more SLIVs to activate SPS or a CG. The apparatus transmits the multiple PUSCHs or receiving the multiple PDSCHs based on a selected SLIV of the TDRA row. The apparatus may select the first SLIV for transmission of the multiple PUSCHs or reception of the multiple PDSCHs if a row indicated by the DCI comprises a plurality of SLIVs.

Abstract: Apparatus, methods, and computer-readable media for facilitating techniques for phase continuity of sidelink DMRS bundling are disclosed herein. An example method for wireless communication at a first UE includes receiving a first sidelink transmission including at least a first DMRS. The example method also includes receiving a second sidelink transmission, the first sidelink transmission and the second sidelink transmission together including at least the first DMRS and a second DMRS. The example method also includes receiving, from a second UE, an indication of a bundling relationship between the first sidelink transmission and the second sidelink transmission, the bundling relationship including at least one of strong bundling, weak bundling, or no bundling. The example method also includes performing channel estimation for a channel associated with the first sidelink transmission and the second sidelink transmission based at least in part on the bundling relationship.
