Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.

Abstract: Aspects described herein may enable a network entity to create an mmW cell geometry and/or to seed a base station codebook and a UE codebook to improve a beamforming procedure while maintaining peak performance gain that is provided by scanning narrower beams. The network entity may provide information associated with the base station codebook and the UE codebook to the base station. The network entity may also provide, to the base station, a subframe structure to be used during a beamforming procedure that is based on the base station codebook and the UE codebook. The base station and the UE may perform the beamforming procedure based in the subframe structure using beam orientations indicated in the base station codebook and the UE codebook. From the beamforming procedure, the base station and the UE may determine an access beam to be used in communication between the base station and the UE.

Abstract: A method for communication beam transition in a communication system includes sending beam information on a first communication beam, receiving a beam switch command on the first communication beam, the beam switch command requesting a transition from the first communication beam to a second communication beam, simultaneously sending and receiving information on the first communication beam and the second communication beam, and ceasing sending and receiving information on the first communication beam when transition to the second communication beam is completed.
