Embodiment Construction

[0057] The described techniques relate to an improved method, system, apparatus or apparatus to support reference signal measurement and reporting for new radio (NR) systems. The examples described herein provide a process for enabling a user equipment (UE) to measure the directional beams of a serving base station and one or more target base stations using different antenna sub-arrays. Considering that reference signal measurement and reporting may include several variables (eg, multiple antenna sub-arrays, multiple beam directions, and multiple radio frequency (RF) chains), the base station may instruct the UE to measure reference signals (eg, DRS) during measurement gaps. ) to measure. The base station may indicate to the UE the type of measurement gap from several different measurement gap types, and the UE may perform reference signal measurements according to the indicated type. The measurement gap can be used to measure and determine which beam and subarray pair has th...

Abstract

Systems, methods and devices for wireless communications are described for reference signal measurement and reporting for new radio systems. User equipment (UE) and base stations may coordinate to identify specific beam and subarray pairs for communication. A user equipment (UE) may receive from a base station a measurement gap configuration specifying a measurement gap type of a plurality of different measurement gap types; A first sub-array in the array is used to measure the reference signal to generate a measurement. The UE may generate a measurement report indicating the measurement. The UE may send a measurement report to the base station. The base station may use the measurement reports to select beam and subarray pairs for communication.

Description

[0001] cross reference [0002] This patent application claims US Patent Application No. 15 / 910,765, entitled "Reference Signal Measurement And Reporting For New Radio (NR) Systems," filed March 2, 2018 by Chendamarai Kannan et al., and Chendamarai Kannan et al. Priority to U.S. Provisional Patent Application No. 62 / 467,795, entitled "Reference Signal Measurement and Reporting For New Radio (NR) Systems," filed March 6, 2017; each of which is assigned to Assignee of this application. technical field [0003] The following relates generally to wireless communications and, more particularly, to reference signal measurement and reporting for New Radio (NR) systems. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and the like. These systems are capable of supporting communication with multiple users by sharing available system resources (e...
