Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A user equipment (UE) for receive (RX) beam switching, the UE being adapted to:
use a current UE RX beam to receive data transmitted by a network node;
select a new UE RX beam to replace the current UE RX beam;
after selecting the new UE RX beam, transmit a channel state information (CSI) report to the network node;
after selecting the new UE RX beam and before transmitting the CSI report, continue to use the current UE RX beam to receive data transmitted by the network node; and
after transmitting the CSI report to the network node, replace 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.
