Bandwidth part full-duplex communication techniques

A method of wireless communication, comprising:

• receiving, by a user equipment (UE), from a base station serving a plurality of UEs including the UE over a component carrier bandwidth (CC BW), a request for a reference signal;
• generating, by the UE, the reference signal to be received by the base station while the base station is transmitting downlink traffic to at least one other UE of the plurality of UEs over at least a part of the CC BW;
• receiving, from the base station, downlink control information including an indication of at least one portion of the CC BW activated for full-duplex operations between the base station and the UE;
• and
• transmitting, by the UE, uplink traffic to the base station over the at least one portion of the CC BW, wherein the uplink traffic from the UE is received by the base station while the base station simultaneously transmits downlink information to at least one other UE over the at least one portion of the CC BW.

An apparatus configured for wireless communication, comprising:

• means for receiving, by a base station serving a plurality of user equipments (UEs) over a component carrier bandwidth (CC BW), at least one reference signal from a first set of UEs of the plurality of UEs, wherein the reference signal is received while the base station is transmitting downlink traffic to a second set of UEs of the plurality of UEs over at least a part of the CC BW;
• means for determining, based on the reference signal, a level of interference on transmissions between the base station and the first set of UEs over the at least a part of the CC BW;
• means for determining, based at least in part on interference cancelation capabilities of the base station and the determined level of interference, at least one portion of the CC BW for full-duplex operations;
• and
• means for activating full-duplex operations for the at least one portion of the CC BW, wherein the means for activating full-duplex operations for the at least one portion of the CC BW includes means for enabling uplink reception from the first set of UEs over the at least one portion of the CC BW while transmitting downlink traffic to the second set of UEs over the at least one portion of the CC BW.

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured to:
• receive, by a base station serving a plurality of user equipments (UEs) over a component carrier bandwidth (CC BW), at least one reference signal from a first set of UEs of the plurality of UEs, wherein the reference signal is received while the base station is transmitting downlink traffic to a second set of UEs of the plurality of UEs over at least a part of the CC BW;
• determine, based on the reference signal, a level of interference on transmissions between the base station and the first set of UEs over the at least a part of the CC BW;
• determine, based at least in part on interference cancelation capabilities of the base station and the determined level of interference, at least one portion of the CC BW for full-duplex operations;
• and
• activate full-duplex operations for the at least one portion of the CC BW, wherein activating full-duplex operations for the at least one portion of the CC BW includes enabling uplink reception from the first set of UEs over the at least one portion of the CC BW while transmitting downlink traffic to the second set of UEs over the at least one portion of the CC BW.
