Embodiment Construction

[0044] The structure and use of the disclosed embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrations of the specific structure and use of the embodiments, and do not limit the scope of the present invention.

[0045] figure 1 An exemplary communication system 100 is shown. The communication system 100 includes an access node 105 serving UEs such as user equipment (UE) 110 , 112 , 114 , 116 and 118 . In a first mode of operation, communications to and from the UE pass through the access node 105 . In the second mode of operation, communications to and from the UE do not pass through the access node 105, however, the access node 105 typically maintains control of the UE's resources for communications when certain conditions are met. Generally, an access node may also be cal...

Abstract

A method includes receiving, from a second device, a signal using each beam of a first subset of beams of a beam set arranged in a layout, measuring a beam quality of the signal received using each beam of the first subset of beams, estimating a beam quality of the signal for each beam of a second subset of beams of the beam set, the first subset of beams and the second subset of beams comprising different beams, and the estimating being in accordance with the measured signal quality of the first subset of beams, selecting a beam from the beam set, selecting the beam being in accordance with the measured beam quality and the estimated beam quality, and communicating, with the second device, using the beam.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 62 / 798,254, entitled "Beam Management Systems and Methods for Device Communications," filed January 29, 2019, which is incorporated herein by reference middle. technical field [0002] The present invention relates generally to methods and apparatus for digital communications, and in particular embodiments, to beam management methods and apparatus for device communications. Background technique [0003] Fifth generation (5G) new radio (NR) communication systems use millimeter-wave frequencies (e.g. 28GHz) and higher to utilize greater bandwidth, thereby increasing throughput, reducing latency, and increasing space reuse Wait. Beamforming concentrates the transmission-related energy in specific spatial directions rather than spreading it out in an omnidirectional fashion. Beamforming is used at higher operating frequencies to compensate for larger path losses at high frequencies. [0004] The di...
