Claim 0:
1. A method for receive (RX) beam switching, the method being performed by a user equipment (UE) and comprising:
the UE using a current UE RX beam to receive data transmitted by a network node;
the UE selecting a new UE RX beam to replace the current UE RX beam;
the UE after selecting the new UE RX beam to replace the current UE RX beam, transmitting a channel state information (CSI) report to the network node;
after the UE selects the new UE RX beam to replace the current UE RX beam and before transmitting the CSI report, the UE continuing to use the current UE RX beam to receive data transmitted by the network node; and
after selecting the new UE RX beam and after transmitting the CSI report to the network node, the UE replacing the current UE RX beam with the new UE RX beam such that the new UE RX beam instead of the current UE RX beam is used to receive data transmitted by the network node, wherein
each said UE RX beam is beam generated by the UE,
selecting the new UE RX beam to replace the current UE RX beam is performed in response to a trigger from the network node, and
the trigger from the network node indicates that the network node will hold its TX beam constant for an entire reference signal transmission and that no CSI report is expected from the UE for at least a time duration.
