Abstract

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.

Claims (14)

1. A base station, the base station for communicating with one or more wireless transmit/receive units (WTRUs), the base station comprising:

a memory; and

a processor, the processor configured to:

allocate a first full duplex timeslot of a frame of a communication channel to full duplex single channel (FDSC) communication;

allocate a second full duplex timeslot of the frame of the communication channel to FDSC communication;

communicate with a first WTRU via FDSC using the first full duplex timeslot; and

send a downlink half duplex (HD) communication to a second WTRU and receive an uplink HD communication from a third WTRU using the second full duplex timeslot that is allocated to FDSC communication.

2. The base station of claim 1 , wherein the processor is further configured such that the first full duplex timeslot is used exclusively by the base station for communication with the first WTRU.

3. A method performed by a base station, the base station for communication with one or more wireless transmit/receive units (WTRUs), the method comprising:

allocating a first full duplex timeslot of a first frame of a first communication channel to full duplex single channel (FDSC) communication;

allocating a second full duplex timeslot of the first frame of the first communication channel to FDSC communication;

communicating with a first WTRU via FDSC via the first full duplex timeslot; and

sending a downlink half duplex (HD) communication to a second WTRU and receiving an uplink HD communication from a third WTRU using the second full duplex timeslot that is allocated to FDSC communication.

4. The method of claim 3 , further comprising conducting the communication with the first WTRU exclusively via the first full duplex timeslot.
