FULL DUPLEX SINGLE CHANNEL COMMUNICATIONS

Embodiments contemplate TDD systems and techniques where timeslots may be allocated as DL, UL, or FDSC; the base station (BS) may be full duplex singled channel (FDSC) capable; and some, all, or none of the UEs (or WTRUs) may be FDSC capable. In one or more embodiments, FDSC1 timeslots may be contemplated that may be used (in some embodiments perhaps exclusively used) by a pair of radios, for example one BS and one UE, both having FD capability. In one or more embodiments, FDSC timeslots may be shared among a BS with FDSC capability and two or more UEs, that may be half duplex (HD). Embodiments also contemplate various FDD systems and techniques, including full duplex FDD systems and techniques.
