Abstract

In a first configuration, the apparatus may be a base station. The base station adjusts a periodicity for performing a beam sweep, sends information indicating the adjusted periodicity for performing a beam sweep, and performs the beam sweep at the adjusted periodicity. In a second configuration, the apparatus may be a UE. The UE receives information indicating a periodicity for performing a beam sweep from a base station, adjusts the periodicity for performing the beam sweep, and performs the beam sweep at the adjusted periodicity. For both configurations, the beam sweep is a plurality of transmissions of a beam in a plurality of different transmit spatial directions by one of the base station or the UE and a plurality of scans of the beam transmissions in a plurality of different scan spatial directions by another of the one of the base station or the UE.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application No. 14 / 301,312, filed June 10, 2014, entitled "COORDINATED OPERATIONS OFMILLIMETER WAVELENGTH WIRELESS ACCESS NETWORKS," which is expressly incorporated by reference in its entirety This article. technical field [0003] In general, the present disclosure relates to communication systems, and more specifically, to coordinated operation of millimeter wavelength radio access networks. Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcast. Typical wireless communication systems may employ multiple-access techniques capable of supporting communication with multiple users via sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple access techniques include Code Division Multiple Access (CDMA) sys...
