Patent ID: 8767658

Claim:
A method for sending uplink scheduling grant signaling, applied in an Advanced Long Term Evolution (LTE-A) system, comprising: a base station, according to a number of clusters occupied with non-consecutive resource allocation by a Physical Uplink Shared Channel (PUSCH) of a scheduled user equipment in a component carrier, configuring at least one uplink scheduling grant signaling for the user equipment, wherein each uplink scheduling grant signaling indicates an allocation of resource for one or two clusters occupied by the PUSCH; wherein when non-consecutive resource occupied by the PUSCH is divided into four clusters, the base station configures two uplink scheduling grant signalings indicating allocation of resource for two clusters respectively; when non-consecutive resource occupied by the PUSCH is divided into three clusters, the base station configures one uplink scheduling grant signaling indicating allocation of resource for one cluster, and another one uplink scheduling grant signaling indicating allocation of resource for other two clusters; when non-consecutive resource occupied by the PUSCH is divided into two clusters, the base station configures one uplink scheduling grant signaling indicating allocation of resource for two clusters; and the base station allocating a Physical Downlink Control Channel (PDCCH) for each uplink scheduling grant signaling, and sending the uplink scheduling grant signaling to the user equipment.
