Abstract: A communications apparatus is provided. A controller module generates a suggested sub-frame pattern describing suggested arrangement of one or more almost blank sub-frame(s) in one or more frame(s) and schedules control signal and/or data transmissions according to the suggested sub-frame pattern. A transceiver module transmits at least a first signal carrying information regarding the suggested sub-frame pattern to a peer communications apparatus. The peer communications apparatus does not schedule data transmissions in the almost blank sub-frame(s).

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.

Abstract: A method for coordinating transmissions between different communications apparatuses in a communications system. The method obtains a sub-frame indicator carried in a first control signal transmitted in a control region of a first sub-frame received from an evolved node B (eNB), wherein the sub-frame indicator indicates resource allocation of one or more sub-frame following the first sub-frame. The method then determines whether a second sub-frame following the first sub-frame and received from the eNB is an almost blank sub-frame according to the sub-frame indicator. When the second sub-frame is not the almost blank sub-frame, obtaining information regarding a start position of a data region of the second sub-frame from a second control signal transmitted in a control region of the second sub-frame.
