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: Apparatus, methods, and computer-readable media for facilitating UE indication of SPS PUCCH HARQ feedback location are disclosed herein. An example method for wireless communication at a UE includes monitoring channel variations for SPS signaling associated with multiple SPS configurations. The example method also includes indicating a feedback occasion for providing SPS PUCCH feedback to a base station for at least one SPS configuration of the multiple SPS configurations, the feedback occasion located within a subsequent cycle.

Abstract: A radio access network (RAN) entity transmits a first transmission configuration indicator (TCI) state activation message, mapping first and second TCI states and a first multiple transmission and reception point (mTRP) configuration (if included) to a first TCI codepoint. The RAN entity also transmits a second TCI state activation message, mapping third and fourth TCI states and a second mTRP configuration (if included) to a second TCI codepoint. The first and second TCI codepoints are activated. The first and second TCI codepoints are associated with a first downlink control information (DCI) format and a second DCI format, respectively. In some aspects, TCI states and mTRP configurations (if included) are activated and mapped to one TCI codepoint, where the first and second TCI states and first mTRP configuration are associated with a first DCI and the third and fourth TCI states and second mTRP configuration are associated with a second DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a physical uplink shared channel (PUSCH) repetition overlaps with an idle period associated with a fixed frame period for communicating over an unlicensed channel in a frame based equipment mode. The UE may refrain from transmitting over the unlicensed channel during one or more symbols of the PUSCH repetition that coincide with the idle period. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently selecting resources for sidelink communications in a shared spectrum while allowing other user equipment (UEs) a chance to gain access to the shared spectrum. In one aspect, a UE may transmit sidelink data to another UE in accordance with a frequency hopping pattern to randomize interference and improve throughput. According to some aspects, the first UE may transmit the sidelink data on a first set of interleaved frequency resources in a first time interval and a second, different set of interleaved frequency resources in a second time interval. In another aspect, a UE may rely on feedback from other UEs to determine when reserved resources are released, and the UE may use the released resources for sidelink communications.
