Patent ID: 10454630

Abstract:
A user equipment includes a processor and a non-transitory computer-readable storage medium storing a program. The program includes instructions to determine a frame structure of a serving cell. Each frame based on the frame structure comprises 2k subframes having at least: (N−1) downlink subframes, (N−1) uplink subframes, and one special subframe which is a first or second special subframe. N and k are each positive integers greater than or equal to 1. The program has instructions to send and receive information in frames based on the frame structure. Each frame has N downlink subframes, N uplink subframes, and (2k−2N) special subframes, where N is less than k, or N downlink subframes, (N−1) uplink subframes, and one second special subframe, where N is equal to k, or (N−1) downlink subframes, N uplink subframes, and one first special subframe, where N is equal to k.
