METHOD AND DEVICE FOR PERFORMING CARRIER SCHEDULING

China Academy of Telecomm...

1. A method for scheduling over a carrier, the method comprises:measuring, by a UE, an uplink channel in uplink sub-frames or an uplink measurement period of time over an unlicensed carrier and a downlink channel in downlink sub-frames over the unlicensed carrier;
determining, by the UE, uplink channel quality information and downlink channel quality information according to a result of the measuring; and
notifying, by the UE, a network-side device of the uplink channel quality information and the downlink channel quality information;
wherein the uplink channel quality information is used for the network-side device to determine to schedule or not to schedule the UE in the uplink over the unlicensed carrier; and the downlink channel quality information is used for the network-side device to determine to schedule or not to schedule the UE in the downlink over the unlicensed carrier;
wherein the uplink channel quality information comprises a part or all of the following information:
a Received Signal Strength Indicator (RSSI), a success probability of potential competition for the uplink channel, the number of devices in an enabled operating state over the unlicensed carrier in each other unlicensed system than a system where the UE is located, and a total power of the other unlicensed systems than the system where the UE is located, over the unlicensed carrier;
and wherein measuring, by the UE, the uplink channel comprises:
when the uplink channel quality information comprises the number of devices in an enabled operating state over the unlicensed carrier in each other unlicensed system than the system where the UE is located, determining, by the UE, the number of devices through a first standalone module configured in the UE to operate in the other unlicensed system; and
when the uplink channel quality information comprises the total power of the other unlicensed systems than the system where the UE is located, over the unlicensed carrier, determining, by the UE, the total power through second standalone modules configured in the UE to operate in the other unlicensed systems.
