Abstract: 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.

Abstract: A network control device. A wireless communications module receives a plurality of first signals each including information regarding a preferred transmitting beam in a first beam level determined by a communications apparatus. A controller selects a group of communications apparatuses to join a 1-to-many beam training according to the received first signals and selects one or more transmitting beams in a second beam level to be trained. The communications apparatuses in the group have the same preferred transmitting beam in the first beam level and the transmitting beam(s) in the second beam level associates with the preferred transmitting beam in the first beam level. The wireless communications module further uses the transmitting beam(s) in turn to transmit signals to perform the 1-to-many beam training for training the transmitting beam(s) in the second beam level among the group of communications apparatuses at the same time.
