Claim of US Patent No. 9,742,532

1. A method for using a user equipment identity, comprising:
configuring, for a user equipment performing carrier aggregation, uniform radio network temporary identity RNTI(s) in cells
where the carrier aggregation is performed;

the network side and the user equipment performing data reception and transmission using the uniform RNTI(s) configured in
the cells where the carrier aggregation is performed,

wherein the network side configuring, for the user equipment performing carrier aggregation, the uniform RNTI(s) comprises:
the network side configuring a same C-RNTI for the UE in the different cells where the carrier aggregation is performed, the
same C-RNTI is different from RNTI(s) which the network side configured for another UE and/or other RNTI(s) which the network
side configured for the UE; or

the network side not configuring a new C-RNTI(s) for UE when the network side configures the carrier aggregation or when the
network side configures and activates the carrier aggregation.
