Network initiated reselection of transmitter and receiver configurations
A network initiated procedure is introduced for updating an SS-BPL once the gNB TX beam and wireless device RX beam start to become misaligned due to movement/rotation of the wireless device. When the gNB measures and determines that a re-establishment of the SS-BPL should be performed, the gNB transmits a trigger signal to the wireless device to update the SS-BPL. In one embodiment, the trigger signal may initiate a new SS block measurement by the wireless device, and a transmission of an uplink signal (e.g., a PRACH transmission) to indicate to the gNB the new preferred SS block and thus a new SS-BPL. In another embodiment, the gNB determines a new SS block for the wireless device and indicates directly in a message from gNB to wireless device an SS block selected by the gNB to use for SS-BPL in subsequent transmissions.
