Title:
UPLINK DATA TRANSMISSION METHOD AND APPARATUS WITH SHORTENED TIME DELAY, AND COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/070824
Kind Code:
A1
Abstract:
An uplink data transmission method and apparatus with a shortened time delay, and a communications system. The uplink data transmission method comprises: receiving resource indication information sent by a base station, wherein the resource indication information indicates the availability for a first user equipment to use a semi-persistent resource on one or more TTIs or subframes; determining a sending resource from the semi-persistent resource according to the resource indication information when uplink data needs to be sent; and using the sending resource to send the uplink data. Thus, not only can the time delay of uplink data be remarkably shortened, but a semi-persistent resource can also be allocated to the other user equipments, thus avoiding wasting the semi-persistent resource as much as possible, and at the same time, the resource utilization efficiency and transmission time delay performance of a user equipment can be improved.
