Claim of US Patent No. 10,362,566

1. An enhanced CA PUCCH method in a UE, comprising the following steps:Step A: receiving a first high layer signaling, wherein the first high layer signaling indicates a reserved SR resource on a first serving cell;
Step B: determining a target serving cell for transmitting SR indication information on a first sub frame, wherein the target serving cell is one of K candidate serving cells and how to determine the target serving cell is UE implementation related; and
Step C: transmitting the SR indication information on the first sub frame of the target serving cell;
wherein the first serving cell is one of K candidate serving cells, the reserved SR resource is a PUCCH resource, K is a positive integer, and the SR indication information indicates a positive SR or a negative SR;
wherein the UE is configured with a PUCCH of a target format on other serving cells except for the first serving cell of the K candidate serving cells; and wherein the target format simultaneously transmits SR bit and PUCCH format of HARQ_ACK.
