Patent ID: 8594057

Claim:
A semi-persistent scheduling method, comprising: at a semi-persistent scheduling periodicity interval, an evolved node B (eNB) and a terminal (UE) select a sub-frame from a sub-frame group as a sub-frame for the current semi-persistent scheduling, wherein the sub-frame group including multiple sub-frames and a sub-frame group periodicity is equal to the semi-persistent scheduling periodicity, wherein during a semi-persistent scheduling, a sub-frame selected by the eNB from a sub-frame group for the current semi-persistent scheduling and a sub-frame selected by the UE from the sub-frame group for the current semi-persistent scheduling have the same relative position in the sub-frame group; and a sub-frame selected for a semi-persistent scheduling and a sub-frame selected for an immediately next semi-persistent scheduling have different relative positions in their respective sub-frame groups, wherein the sub-frame group periodicity refers to the number of sub-frames between two sub-frames with the same relative position in their respective sub-frame groups, the two sub-frame groups for the two sub-frames are successive and with no other sub-frame group in between; wherein for any two successive schedulings with no other scheduling in between, the sub-frames for the two successive schedulings have different relative positions in their respective sub-frame groups.
