Abstract:
Wireless communication techniques that include beam training performed to aid mobile devices in identifying beams for use in communications (e.g., uplink communications) are discussed. A mobile device may transmit to a base station an indication of a level of beamforming reciprocity of the mobile device. A base station/gNB may transmit an indication of one or more transmission beams to be used by the mobile device for uplink wireless communication based on the level of beamforming reciprocity. The one or more transmission beams to be used by the mobile device for uplink communication may include a reciprocal transmission beam. A mobile device not capable of full beamforming reciprocity may determine a transmission beam through uplink beam training. A mobile device may transmit to a base station information using at least one of the one or more transmission beams. Other aspects and features are also claimed and discussed.
