RESOURCE SCHEDULING METHOD, APPARATUS AND BASE STATION
First Claim
1. A resource scheduling method, comprising:
- determining whether to set a semi-persistent scheduling scheme for a User Equipment, UE, upon determining a cell serving the UE as an interference limited cell with a traffic load of a downlink control channel of the interference limited cell being above a preset traffic load threshold;
configuring the UE with semi-persistent scheduling parameters upon determining the semi-persistent scheduling scheme to be set for the UE;
allocating a semi-persistent scheduling resource for transmitting service data of an access service for the UE according to the semi-persistent scheduling parameters upon determining the UE to transmit the service data in the semi-persistent scheduling scheme; and
sending resource scheduling information of the allocated semi-persistent scheduling resource to the UE on the downlink control channel of the UE.

Abstract
Disclosed are a resource scheduling method, apparatus and base station for reducing the signaling overhead of the downlink control channel instruction in uplink and downlink data transmission. The method comprises: configuring semi-persistent scheduling parameters for a user equipment (UE) when the cell of the UE is determined to be an interference limited cell and a semi-persistent scheduling mechanism needs to be set for the UE; allocating semi-persistent scheduling resources to the UE for transmitting service data according to the semi-persistent scheduling parameters when the UE is determined to be in need of a semi-persistent scheduling mechanism for transmitting the service data of access services; sending the resource scheduling information of the semi-persistent scheduling resources to the UE over the downlink control channel of the UE. The technical solution provided in the present application reduces the signaling overhead of the downlink control channel instruction during data transmission, reduces inter-cell interference of the downlink control channel, and improves the reception capability of the downlink control channel, quality of service (QoS) and cell spectrum efficiency.
