Methods exploiting asymmetric capabilities for contention-based random access in mm-wave access systems
First Claim
1. A method of wireless communication for a user equipment (UE), comprising:
- receiving beamforming capability information indicating one of at least a digital, analog, or hybrid beamforming capability, and including an RF beam switching speed, the beamforming capability being associated with a millimeter wave base station (mmW-BS);
scanning, based on the beamforming capability information including the RF beam switching speed, N transmit beams from the mmW-BS for each of M receive beam directions of the UE, the scanning including selecting a frame structure for the scanning based on the RF beam switching speed of the mmW-BS;
determining one or more preferred scanned beams from among the N transmit beams; and
establishing a wireless communication link with the mmW-BS based on the preferred one or more scanned beams.

Abstract
A method, an apparatus, and a computer program product for operating a user equipment (UE) are provided. The apparatus receives beamforming capability information indicating one of at least a digital, analog, or hybrid beamforming capability, the beamforming capability associated with a millimeter wave base station (mmW-BS). Based on the beamforming capability information, the apparatus scans N transmit beams from the mmW-BS for each of M receive beam directions of the UE, determines one or more preferred scanned beams from among the N transmit beams, and establishes a wireless communication link with the mmW-BS based on the preferred one or more scanned beams.
