Techniques for beam shaping in millimeter wave base stations and fast antenna subarray selection in wireless devices

摘要

A method, system, and device for wireless communication in user equipment (UE) are described. A wireless communication system may improve UE discovery latency by dynamically selecting and switching beamforming codebooks at millimeter wave base stations and wireless devices. By selecting the optimal beamforming codebook, the wireless communication system may be able to improve the link margin between base stations without compromising resources. In some examples, a wireless device determines whether a received signal from a millimeter wave base station meets an established signal-to-noise (SNR) threshold and establishes an optimal beam codebook to establish communication. Can be selected. Additionally or alternatively, the wireless device may further signal the selected beam codebook to the millimeter wave base station and instruct the millimeter wave base station to adjust the codebook based on the selection.
