AI Technical Summary

Problems solved by technology

Therefore, SSB measurements for BM (e.g. for beam measurement and reporting based on narrow UE beams) cannot be shared with RRM
This results in a reduced measurement update rate which can reduce beam reporting reliability and thus also UE mobility performance

Abstract

Methods performed by a user equipment (UE) include selecting at least one synchronization signal block (SSB) resource ID based on measurements of a second signal block, wherein the second signal block comprises a system information block (SIB) in 5G new radio (NR) that is spatially quasi co-located (QCLed) with the SSB resource ID. Methods performed by a UE further include performing measurements of downlink (DL) reference resources (RS) allocated by a next generation NodeB (gNB) in a frequency range (FR), generating reporting messages based on at least the measurements and transmitting the reporting messages to the gNB. Methods performed by a gNB include allocating downlink (DL) reference resources (RS) in a frequency range (FR) for the UE and receiving or causing reception of reporting messages containing measurements by the UE for the DL RS.

Description

[0001] Priority request / incorporate [0002] The present disclosure claims the on May 10, 2019 entitled "SYNCHRONIZATION SIGNAL BLOCK (SSB) BASED BEAM MEASUREMENT AND REPORTING IN 5G NR" U.S. Provisional Patent Application Serial No. 62 / 846,254, the disclosure of reference incorporated herein. Background technique [0003] Beamforming technology can significantly improve the efficiency of network resources, and is one of the main innovative new radio 5G (NR) in. In the frequency range 5G NR 1 (FR1) (6GHz sub-bands) may be deployed in a g-NodeB (gNB) is formed based on the analog side beam antenna array. In the frequency range 5G NR 2 (FR2) (a millimeter wave band), the side and the UE gNB deployed antenna beam formed based. Collecting beam may be applied to find the GNB (in FRl) or best beam at the UE and GNB (in FR2) between the best beam pair. When the UE is gNB identification (and UE) at the start of the best beam is configured to communicate, not only for the initial acces...
