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: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information message to a user equipment (UE) that includes both a first indication of one or more transmission configuration indicator (TCI) states for the UE to use for communications with the base station and a second indication of one or more uplink transmissions to be sent by the UE. In some implementations, the UE may use one of the one or more indicated TCI states to communicate with the base station after a delay (or offset) from sending an uplink transmission of the one or more uplink transmissions. For example, the delay may include an amount of time or a quantity of symbols between transmitting the uplink transmission of the one or more uplink transmissions and communicating with the base station using the one of the one or more indicated TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, assistance information that indicates a packet data convergence protocol (PDCP) preference for multiple connectivity communications from a master node and one or more secondary nodes; and receive, from the base station, a communication that indicates a routing of a sequence of PDCP packages across the master node and one or more active secondary nodes. Numerous other aspects are provided.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: This disclosure provides systems, methods and apparatus for multi-beam operation at a user equipment (UE). In some aspects, a user equipment (UE) may transmit a beam report indicating a number of simultaneous transmit beams supported by the UE. The UE may receive a common beam indication for multiple TCI states. The UE may select at least one TCI state as an uplink component for a common beam and may communicate with a base station (BS) using the common beam. The UE may receive control signaling enabling a group-based beam reporting mode at the UE and an indication to apply a group-based beam reporting configuration for uplink beam reporting. The UE may selectively enable or disable the group-based beam reporting configuration. The UE may report multiple reference signal resource indices for multiple reference signals. The UE may transmit the reference signals using multiple spatial domain transmit filters.
