Full-duplex communications

A method for full-duplex mode wireless communication by a user equipment (UE), the method comprising:

• receiving, from a base station (BS):
• an indication of a first uplink timing advance (TA), and
• an indication of a first cyclic prefix (CP) length determined based on the first uplink TA;
• transmitting, to the BS, a first uplink communication during a first time window comprising a plurality of time periods, wherein the first uplink communication comprises a first uplink CP having the first CP length;
• and
• receiving, from the BS, a first downlink communication comprising a downlink CP during the first time window, wherein the first uplink CP and the downlink CP at least partially overlap in time from, a perspective of one or more of the UE or the BS.

A base station (BS) configured for full-duplex communication, the BS comprising:

• a memory;
• and
• a processor coupled to the memory, the memory and the processor configured to:
• transmit, to a first user equipment (UE):
• an indication of a first uplink timing advance (TA) determined based on a first propagation delay between the BS and the first UE, and
• an indication of a first cyclic prefix (CP) length determined based on the first uplink TA;
• transmit, to the first UE, a first downlink communication comprising a downlink CP, during a first time window comprising a plurality of time periods;
• and
• receive, from the first UE, a first uplink communication during the first time window, wherein the first uplink communication comprises a first uplink CP having the first CP length, and wherein the first uplink CP and the downlink CP at least partially overlap in time from a perspective of one or more of the the BS or the first UE.
