Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and a network node may determine a configuration that indicates an antenna switching point associated with an uplink communication configured for multiple repetitions. The UE may transmit one or more repetitions of the uplink communication using a first transmit antenna prior to the antenna switching point. The UE may transmit one or more repetitions of the uplink communication using a second transmit antenna after the antenna switching point. The network node may perform channel estimation for the uplink communication based at least in part on the configuration that indicates the antenna switching point. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a default value for a radio parameter used for communicating with a network node based at least in part on whether the network node is a terrestrial network (TN) node or a non-terrestrial network (NTN) node, an orbit type associated with the network node, or a coverage type associated with the network node. The UE may transmit a communication, e.g., to the network node based at least in part on the default value for the radio parameter. Numerous other aspects are described.

Abstract: Embodiments include systems and methods for supporting for supporting retransmission in a multicast session in a Fifth Generation (5G) New Radio (NR) (5G NR) radio access network (RAN). Various embodiments may provide an enhanced multicast radio bearer (MRB) architecture leveraging Packet Data Convergence Protocol (PDCP) status reporting by wireless devices to a base station of a 5G NR RAN. Various embodiments may support multiple Radio Link Control (RLC) entities, also referred to as RLC legs, in a multicast session. One or more multicast RLC legs may be used for multicast and/or unicast transmission to wireless devices and a unicast RLC leg may be used for unicast transmission to a specific wireless device. Various embodiments may enable PDCP level retransmission of PDCP protocol data units (PDUs).

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may determine a beam configuration associated with a set of directional beams of a base station. The beam configuration may include a set of identifiers associated with the set of directional beams. The UE may determine beam position information associated with a coverage area of each directional beam of the set of directional beams based on the beam configuration. Additionally or alternatively, the UE may determine beam classification information associated with the coverage area of each directional beam of the set of directional beams based on the beam configuration. The UE may select a directional beam of the set of directional beams based on the beam position information and the beam classification information, and communicate with the base station using the selected directional beam.
