Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration and processing enhancements. A method generally includes receiving, from the network, signaling indicating a sounding reference signal (SRS) configuration allocating a plurality of symbols for SRS transmissions within an uplink (UL) subframe, detecting a collision between at least one of the allocated SRS symbols and another type of UL transmission, and taking one or more actions regarding the SRS transmissions, based on the detection of the collision.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a relationship between a first set of antenna ports, used for demodulation reference signals (DMRS) associated with a machine-type communication physical downlink control channel (MPDCCH) and used for the MPDCCH, and a second set of antenna ports used for cell-specific reference signals (CRS); receive CRS on one or more antenna ports of the second set of antenna ports; and receive the MPDCCH using at least the CRS based at least in part on the relationship. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit DCIs to a UE to schedule instances of one or more MBS TBs, the multiple instances of the one or more TBs being time-interleaved. For example, the network entity may transmit a first set of DCIs scheduling a first set of instances of a first TB, and a second set of DCIs scheduling a second set of instances of a second TB, where at least one instance of the first set of instances may be interleaved with the second set of instances. In some cases, the first and second set of DCIs may include one DCI to schedule the respective set of instances, or one DCI per instance of the respective set of instances. Additionally, or alternatively, the network entity may indicate one or more parameters to the UE associated with MBS inter-TB time interleaving.

Abstract: In some implementations, a location server may, in a positioning session between the location server and a user equipment (UE): receive, from the UE, a report message comprising reference signal time difference (RSTD) measurement information of an RSTD measurement, performed by the UE, of radio frequency (RF) signals, wherein: at least one RF signal of the RF signals is transmitted by an NTN Next Generation Radio Access Network (NG-RAN) node, and the RSTD measurement information comprises an offset to compensate for a delay in the at least one RF signal. The location server may determine a position of the UE based at least in part on the RSTD measurement information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, while operating using a first beam corresponding to a cell, a second beam corresponding to the cell based at least in part on a set of beam information associated with the second beam, wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam. The UE may communicate with a wireless communication device that provides the cell using the second beam. Numerous other aspects are provided.
