Title:
METHOD AND APPARATUS FOR SENDING UPLINK INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/024564
Kind Code:
A1
Abstract:
A method for sending uplink information. In the solution, a user equipment does not need to acquire synchronization by means of a random access process, that is, the user equipment can determine timing advance information without needing to send random access codes, thereby reducing interactions of random access codes between the user equipment and a network side device. Accordingly, the defects of long delay and low efficiency of uplink HARQ feedback in sending uplink data or downlink data in the prior art are resolved.
