US 10,312,988 B2 · Two reference signal beam reporting and identification

Abstract

Various embodiments disclosed herein provide for a beam reporting and identification system that can use two different types of signals as reference signals when reporting on beam strengths. The user equipment device can send a unified report that reports on each of the different types of reference signals using a unified beam index. In an embodiment, the first type of reference signal can be a user equipment (UE) specific reference signal, such as a channel state information reference signal (CSI-RS), while the second type of signal used as a reference signal can be a synchronization signal (SS), received as an SS block. The unified index, where SS blocks are grouped into a number of groups, allows for the same number of bits to report on both synchronization signals and CSI-RS signals in the same report.

Dependent claims

A user equipment device, comprising:

a processor;
and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
generating a beam index comprising a first group of signal measurements of a first type of reference signal, and a second group of signal measurements of a second type of reference signal;
transmitting a first report to a network node comprising a first signal measurement of a first beam of the first group of signal measurements in response to the first signal measurement of the first beam being determined to be above a defined signal strength;
and
transmitting a second report to the network node comprising a second signal measurement of a second beam of the second group of signal measurements in response to each signal measurement of the first group of signal measurements being below the defined signal strength, wherein the second signal measurement of the second beam has the highest signal strength of the second group of signal measurements.
