Embodiment Construction

[0056] A wireless communication system may support communication between base stations and user equipment (UE). Specifically, a wireless communication system can support downlink transmissions from base stations to UEs and uplink transmissions from UEs to base stations. Uplink transmissions may include data, control signals, and reference signals (eg, Sounding Reference Signals (SRS), etc.). In some cases, a UE may transmit reference signals via multiple antennas using multiple-input multiple-output (MIMO) techniques. Different reference signal waveforms may be multiplexed over a set of frequency resources (eg, using frequency division multiplexing (FDM) and / or time division multiplexing (TDM)) for a given uplink transmission on the antenna. For example, the UE can identify individual single carrier reference signal streams to be sent to the base station, and can precode and multiplex these streams for transmission. In some cases, the same precoder may be applied across the ...

Abstract

The described techniques provide for the use of sub-band-specific reference signal precoding. A user equipment (UE) may apply multiple precoding matrices to a reference signal to generate a set of precoded reference signals and may transmit the precoded reference signals over respective sub-bands within a given reference signal resource set. In some cases, the UE may transmit a different set of precoded reference signals in each of multiple reference signal resource sets. Upon receiving the precoded reference signals, a base station may perform wideband channel estimation for each sub-band inthe given reference signal resource set. The base station may compute an average spectral efficiency for each reference signal resource set and may transmit a report to the UE. The report may includeone or more communication parameters for future communications between the UE and base station.

Description

[0001] cross reference [0002] This patent application claims to enjoy the rights and interests of the international patent application No.PCT / CN2017 / 088702 entitled "FREQUENCYSELECTIVE UPLINK PRECODING FOR NEW RADIO" submitted by HAO et al. on June 16, 2017, which has been assigned to this application assignee, which is hereby incorporated by reference in its entirety. technical field [0003] In general, the following relates to wireless communications, and more specifically, the following relates to frequency selective uplink precoding for new radios. 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 so on. These systems may be capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple-access systems may include Code Division Multiple A...
