Abstract:
A method for receive (RX) beam switching is provided. The method may be performed by a user equipment (UE) (420). The method includes using a current RX beam (412) to receive a transmission from a network node (422). The method further includes selecting (706) a new RX beam (414) to replace the current RX beam (412). The method further includes, after selecting (706) the new RX beam (414), transmitting (708-710) a channel state information (CSI) report to the network node (422). The method further includes, after selecting (706) the new RX beam (414) and before transmitting (708-710) the CSI report, continuing to use the current RX beam (412) to receive transmissions from the network node (422). The method further includes, after transmitting (708-710) the CSI report to the network node (422), replacing (714) the current RX beam (412) with the new RX beam (414) such that the new RX beam (414) instead of the current RX beam (412) is used to receive transmissions from the network node.
