实施方式涵盖TDD系统和技术，其中时槽可以被分配为DL、UL或FDSC；基地台（BS）可以为有全双工单频道（FDSC）能力；并且一些、所有或者无UE（或WTRU）为有FDSC能力。在一个或多个实施方式中，可以涵盖FDSC时槽可以被一对无线电使用（在一些实施方式可能为排它性地使用），所述一对无线电诸如为都具有FD能力的一个BS和一个UE。在一个或多个实施方式中，FDSC时槽可以在具有FDSC能力的BS和为半双工（HD）的两个或多个UE之间共享。实施方式还涵盖各种FDD系统和技术，包括全双工FDD系统和技术。

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, FDSC 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.
