Abstract: A method of wireless communication performed by a base station includes receiving one or more particular signals. The method further includes receiving one or more transmissions associated with a first CC and a second CC. The one or more transmissions include first data and a first demodulation reference signal (DMRS) that are associated with the first CC, and the one or more transmissions further include second data and a second DMRS that are associated with the second CC. A determination whether to demodulate the second data using the first DMRS is based on the one or more particular signals.

Abstract: Methods, systems, and devices for sidelink groupcast communications are described. A user equipment (UE) may transmit a beam training request to a base station to determine beams for use with other UEs in a sidelink groupcast communications group. The base station may receive the beam training request, identify wireless resources that a group of UEs may use to perform beam training, and may transmit a beam training grant to each UE of the group of UEs. The UE may transmit a number of training beams using the wireless resources provided in the beam training grant, and the other UEs may measure received signals on the wireless resources to identify one or more beams. Each UE may provide a beam training report to the base station. The base station, based on the beam training reports, may determine beams and resources for use in the groupcast sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may accumulate a number of hybrid automatic repeat request (HARQ) bits as a result of one or more resource conflicts and may store the number of HARQ bits for a later transmission opportunity. The UE may transmit a scheduling request that requests resources for a transmission of the number of HARQ bits that are stored at the UE as a result of the number of HARQ bits satisfying a triggering condition. For example, the UE may transmit the scheduling request if a quantity of the number of HARQ bits satisfies a threshold quantity. Additionally or alternatively, the UE may transmit the scheduling request if the number of HARQ bits include triggering content. For example, the UE may transmit the scheduling request if any HARQ bit stored at the UE conveys a negative acknowledgement (NACK).

Abstract: Aspects relate to measuring and scheduling reference signals. A user equipment (UE) detects reference signals having overlapping resources, and determines a context associated with the reference signals. A Layer 1 (L1) measurement is then performed of at least one reference signal according to a prioritization associated with the context. In another aspect, a network entity determines a scheduling of resources that enables a UE to prioritize performing an L1 measurement of a reference signal from a non-serving cell, and communicates with the UE according to the scheduling.

Beam failure detection (BFD) reference signals are then identified explicitly via a configuration signaling, or implicitly based on the TCI states. The BFD reference signals are then monitored to facilitate detecting a beam failure event.
