Abstract:
1. A method of operating a base station in a wireless network, comprising: allocating radio resources for a user equipment in frames of a plurality of frame types including a first frame type and a second frame type, wherein each frame includes a preamble distinguishing that frame from frames of other frame types; forming an interlaced frame by interlacing the frames of the plurality of frame types so that in the interlaced frame: a downlink portion of a frame of the first frame type does not overlap with an uplink portion of a frame of the second frame type, and an uplink portion of the frame of the first frame type does not overlap with a downlink portion of the frame of the second frame type; and communicating with the user equipment according to the interlaced frame, wherein: the interlaced frame comprises a plurality of sequences including a first sequence and a second sequence, each of the first sequence and the second sequence comprising a downlink portion followed by an uplink portion; in the first sequence, the downlink portion includes a first synchronization point and downlink resources corresponding to the first frame type and the uplink portion includes uplink resources corresponding to the second frame type; and in the second sequence, the downlink portion includes a second synchronization point and downlink resources corresponding to the second frame type and the uplink portion includes uplink resources corresponding to the first frame type; and wherein the interlaced frame includes: a second cell identifier indicating that one or more frames of the second frame type are associated with a second cell, wherein the first cell identifier and the second cell identifier each correspond to a respective base station or a respective combination of a base station and a sector of the base station.
