Methods for efficient beam training and communications apparatus and network control device utilizing the same
First Claim
1. A network control device, comprising:
- a wireless communications module, using a preferred transmitting beam to communicate with a communications apparatus in one or more downlink opportunities corresponding to the preferred transmitting beam; and
a controller, scheduling signal or data to be transmitted in at least one downlink opportunity corresponding to the preferred transmitting beam,wherein 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, andwherein the controller further assigns an identifier to the communications apparatus after a random access procedure of the communications apparatus is completed, and obtains information regarding a position of the training gap according to the identifier assigned to the communications apparatus.

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.

8. A communications apparatus, comprising:
-
a wireless communications module, capable of supporting a plurality of receiving beams and using a preferred receiving beam to communicate with a network control device in one or more downlink opportunities corresponding to a preferred transmitting beam of the network control device, wherein the preferred receiving beam and the preferred transmitting beam are determined in a previous beam training procedure; and a controller, training at least one receiving beam other than the preferred receiving beam in at least one training gap of at least one downlink opportunity corresponding to the preferred transmitting beam by using the at least one receiving beam other than the preferred receiving beam to receive signals transmitted by the network control device via the preferred transmitting beam in the training gap, wherein the controller further obtains information regarding a position of the training gap according to an identifier assigned by the network control device after a random access procedure is completed. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

21. A method for efficient beam training, comprising:
-
training at least one receiving beam other than a preferred receiving beam of a communications apparatus in at least one downlink opportunity corresponding to a preferred transmitting beam of a network control device by using the at least one receiving beam other than the preferred receiving beam to receive signals transmitted by the network control device in at least one training gap of the downlink opportunity corresponding to the preferred transmitting beam, wherein the preferred receiving beam and the preferred transmitting beam are determined in a previous beam training procedure; using the preferred receiving beam to receive signal or dedicated data from the network control device in the remaining time of the downlink opportunity corresponding to the preferred transmitting beam; and obtaining information regarding a position and/or a duration of the training gap according to an identifier assigned by the network control device to the communications apparatus after a random access procedure is completed. - View Dependent Claims (22, 23, 24)
