Abstract: The embodiments of this invention propose methods of physical resource allocation for UL control channels including PUCCH and PRACH in adaptive TDD systems. In an adaptive TDD system, there are multiple types of UL-DL configuration, e.g. System configuration, UL-reference configuration (same to System configuration), DL-reference configuration (different from System configuration) and actual configuration. If legacy UE and eIMTA UE respectively follow System configuration and DL-reference configuration to feedback DL HARQ-ACK and corresponding PUCCH resources are implicitly determined by CCE index, PUCCH resource collision may happen, i.e. multiple PUCCHs are transmitted in single resource. The problem of PUCCH resource collision will cause PUCCH performance degeneration and needs to be resolved. Some solutions are proposed in the invention to resolve this problem.
