Title:
DATA SENDING METHOD, AND SIGNALING SENDING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/028657
Kind Code:
A1
Abstract:
Disclosed in the present application are a data sending method, and a signaling sending method, apparatus and system, which relate the field of communications. The method comprises: a terminal receives a downlink reference signal sent by an access network device; the terminal measures the downlink reference signal to obtain a plurality of uplink precoding vectors; the terminal sends SRSs to the access network device on the plurality of uplink SRS resources, different SRSs sent on different uplink SRS resources being precoded by using different uplink precoding vectors; the terminal receives uplink scheduling signaling sent by the access network device, the uplink scheduling signaling being used for indicating a resource index of at least one uplink SRS resource; the terminal precodes uplink data according to an uplink precoding vector corresponding to the resource index; and send the precoded uplink data to the access network device. The present application can improve transmission perform of uplink data.
