Method for indicating resource allocation information, base station, user equipment, and storage medium

Abstract

Embodiments of the present invention provide a method for indicating resource allocation information, a base station, user equipment, and a system. By adopting the technical solution of the embodiment of the present invention, the base station generates and sends downlink control information including public resource allocation indication information to UE. The public The resource allocation indication information is used to indicate the resources allocated to multiple UEs, and the UE obtains the information of the allocated resources according to the common resource allocation indication information, which reduces the amount of resources occupied by the resource allocation indication, thereby reducing the overall DCI resource amount, The signaling overhead of the system is saved. Especially, the method is applied in the scenario of performing short subframe services, which further reduces signaling overhead and improves system performance.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and in particular to a base station, user equipment and storage medium for a method for indicating resource allocation information. Background technique [0002] The uplink data transmission process in the long term evolution (LTE) system mainly includes the following steps: first, the user equipment (user equipment, UE) sends a scheduling request (scheduling request, SR) message to the base station; then, the base station sends a resource allocation (scheduling grant, SG) information to the UE; the UE sends data on the resources allocated by the base station. [0003] Wherein, the SG information is transmitted through downlink control information (downlink control information, DCI). The DCI generally includes a resource allocation indication (bitmap), a modulation and coding scheme, and other information. After receiving the DCI, the UE can obtain the allocated r...

Problems solved by technology

[0004] In the prior art, the bitmap in the DCI sent by the base station to a certain UE is only used to indicate the resource allocation of the UE, and sending each bitmap needs to occupy a certain amount of resources. As the number of UEs accessing the base station increases, all bitmaps occupy The overall resources of the system are multiplied. When the number of UEs is too large, the system signaling overhead will be too large.
