Apparatus and method for discontinuous receive in communication systems with large number of antennas

摘要

A user equipment (UE) performs a method for supporting discontinuous receive (DRX) in a wireless network. The method includes waking up at a wake up time associated with a beginning of a DRX cycle, the DRX cycle comprising a plurality of subframes. The method also includes determining whether to perform receive beam training before a beginning of a time period for downlink communication. The method further includes receiving data during the time period for downlink communication.

1. A method for supporting discontinuous reception (DRX) by a user equipment (UE) in a wireless network, the method comprising:
waking up at a wake up time associated with a beginning of a DRX cycle, the DRX cycle comprising a plurality of subframes; determining, as a function of one of a sleeping duration time and a velocity of the UE, whether to perform receive beam training before a beginning of a time period for downlink communication; and receiving data during the time period for downlink communication, through either a previous receive beam or a newly trained receive beam depending on the determination.
