摘要： A new beam identification method is proposed. The UE determines (301) whether a quality of at least one NBI-RS resource associated with a serving Transmission and Reception Point (TRP)is larger than or equal to a first threshold. The UE determines (302) whether a quality of at least one NBI-RS resource associated with at least one candidate TRP is larger than or equal to a second threshold. The UE selects (303) a new beam for a recovery procedure based on determining results associated with the serving TRP and the at least one candidate TRP.

摘要： A network control device includes a controller and a wireless communications module. The controller provides a plurality of signaling entities each belonging to one of a plurality of signaling levels to form multi-level signaling entities and configures one or more signaling entities of the multi-level signaling entities to a communications apparatus to communicate with the communications apparatus based on the one or more configured signaling entities. The wireless communications module transmits a plurality of radio frequency signals via the one or more configured signaling entities.

摘要： A method of beam misalignment detection for wireless communication system with beamforming is proposed. To identify a misaligned beam, a relative beam quality degradation is applied by comparing a dedicated beam quality with a reference beam quality. The reference beam favors similar transmission path as the dedicated beam, and has better mobility robustness. In one embodiment, the reference beam is an associated control beam of the dedicated beam. To detect beam misalignment, a first dedicated beam SINR is compared with a second associated control beam SINR.

摘要： A communications apparatus. A first radio module communicates with a first wireless network and provides wireless communications services. A second radio module communicates with a second wireless network and provides wireless communications services. At least two antennas shared by the first radio module and the second radio module. When the first radio module operates in a connected mode and when the timing of the first radio module performing the first receiving activity coincides with the timing of the second radio module performing a second receiving activity, the first radio module reports a value of 1 for a Rank Indicator to the first wireless network at least once before the second radio module is to perform the second receiving activity, and then the second radio module uses one of the antennas to perform the second receiving activity.

摘要： An effective SCELL activation procedure is proposed to reduce the SCELL activation time. For carrier aggregation, a secondary cell (SCELL) needs to be configured and then activated before a UE can perform normal operation. In a first embodiment, the UE performs measurements on a list of candidate SCELLs before SCELL configuration. In a second embodiment, the UE performs measurements on a configured SCELL with high priority after the SCELL is configured. In a third embodiment, the UE performs deactivated-state SCELL measurements with adaptive SCELL measurement interval based on a configured measurement cycle and a state machine. Small SCELL activation time allows energy saving and network scheduling gain.

摘要： A network control device includes a wireless communications module and a controller. The wireless communications module uses a preferred transmitting beam to communicate with a communications apparatus in one or more downlink opportunities corresponding to the preferred transmitting beam. The controller schedules signal or data to be transmitted in at least one downlink opportunity corresponding to the preferred transmitting beam. When scheduling signal or data to be transmitted, the controller further provides at least one training gap, in which the controller does not schedule any dedicated data to the communications apparatus, in the downlink opportunity corresponding to the preferred transmitting beam.
