Title:
UPLINK TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/000119
Kind Code:
A1
Abstract:
Provided are an uplink transmission method and apparatus. When a first data packet and a second data packet are transmitted simultaneously, a UE maps the first data packet to a first time-frequency resource of a time-frequency resource block, maps the second data packet to a second time-frequency resource of the time-frequency resource block, sends the first data packet and the second data packet via different time-frequency resources of the same time-frequency resource block, and feeds back a receiving result of the first data packet and the second data packet by means of a new feedback mechanism. The method can prevent collision between an initially transmitted data packet and a retransmitted data packet in an SPS scene, and to improve the utilization rate of time-frequency resources.
