Display system, power management circuit and related operation method

A communication apparatus comprises a radio transceiver and a modem processor. The radio transceiver is configured to transmit or receive signals. The modem processor is coupled to the radio transceiver and configured to perform operations comprising: performing a beam management, to train a first receiver (Rx) beam; receiving a physical downlink shared channel (PDSCH) according to the first Rx beam; selecting at least one second Rx beam according to a scenario, if a first performance indicator of the first Rx beam is lower than a previous first performance indicator of the first Rx beam by a first threshold; determining at least one second performance indicator of the PDSCH according to a round-robin test; selecting a third Rx beam from the at least one second Rx beam according to the at least one second performance indicator; and receiving the PDSCH according to the third Rx beam.

Communication apparatus and method for handling an Rx beam for the PDSCH reception

Wireless receiver systems and methods for user equipment are described that employ multiple receiver heads. The multiple heads can receive wireless communication signals over different receive paths from different transmission sources. The systems can scan and monitor signal quality from all receiver heads during a scheduled gap in a communication link without interfering with an ongoing communication session.
