Title:
METHOD AND APPARATUS FOR TRANSMITTING AN UPLINK RESPONSE MESSAGE
Document Type and Number:
WIPO Patent Application WO/2015/114451
Kind Code:
A3
Abstract:
An objective of this invention is to provide a method and apparatus for transmitting an uplink response message. Specifically, detecting, by a base station serving a mobile device, whether the mobile device satisfies a scheduling trigger condition for paired scheduling; when the scheduling trigger condition is satisfied and the base station transmits a downlink message to the mobile device, determining, by the base station, uplink resource allocation information of an uplink response message corresponding to said downlink message about the mobile device, so as to send identification information for paired scheduling the mobile device and said uplink resource allocation information to the mobile device; transmitting, by the mobile device, said uplink response message according to said identification information and base on said uplink resource allocation information. Compared with the prior art, in the present invention, the base station transmits identification information to the mobile device which satisfies a scheduling trigger condition for paired scheduling, and uplink resource allocation information of an uplink response message corresponding to the downlink message, such that the base station can allocate UL and DL resource in the same resource allocation message. Thereby, signaling overhead is reduced, and the coverage of the mobile device is enhanced.
