摘要:
One way to increase robustness against beam pair link failure is by transmitting downlink (DL) control signaling (e.g., PDCCH) in more than one beam. That is, one way to mitigate BPLF is for the UE to receive DL control signaling over both a first BPL (e.g., active BPL) and a second BPL (e.g., monitored BPL) but with larger duty cycle for the second BPL compared to the first BPL. For example, the control signaling can be scheduled every slot on the first BPL and scheduled every Nth slot on the second BPL. In this way, in case the first BPL is blocked and the UE cannot decode the control signaling on the first BPL, the UE can receive control signaling transmitted on the second BPL.
