Patent ID: 8687582

Claim:
A method for transmitting semi-persistent scheduling data, comprising: determining an initial transmission carrier for transmitting semi-persistent scheduling data according to channel condition information of each carrier in multiple carriers and a gain of a match of a multi-user multiple-input and multiple-output antenna unit, wherein the determining of the initial transmission carrier comprises: selecting a match of the multi-user multiple-input and multiple-output antenna unit according to a rank indicator, a precoding matrix index, a channel quality indicator or channel state information that are of each carrier in the multiple carriers; and determining the initial transmission carrier according to a gain of the selected match of the multi-user multiple-input and multiple-output antenna unit; instructing a user equipment (UE) to use the determined initial transmission carrier for a subsequent transmission of scheduling data by the UE, wherein the instructing of the UE to use the determined initial transmission carrier for receiving the semi-persistent scheduling data to be transmitted comprises: adding a physical layer channel on each carrier in the multiple carriers, and setting a 1-bit indicator bit in the physical layer channel, wherein the 1-bit indicator bit is for instructing whether the semi-persistent scheduling data is scheduled on the carrier for transmission; or, selecting one downlink main carrier, adding a physical layer channel on the selected downlink main carrier, and setting, in the physical layer channel, an indicator bit of a predetermined length for instructing the initial transmission carrier; and transmitting the semi-persistent scheduling data to the UE through the instructed initial transmission carrier to initiate the transmission of the uplink scheduling data by the UE through the instructed initial transmission.
