1. A method performed by a user equipment (UE) configured as a coordinating user equipment for a user equipment-coordination set (UECS) of UEs connected by a local wireless network in a wireless communications network, the method comprising the coordinating user equipment:
selecting a first subset of UEs in the UECS to jointly receive downlink signals;
selecting a second subset of UEs in the UECS to jointly transmit uplink signals, the UEs included in the second subset of UEs not overlapping with the UEs included in the first subset of UEs;
transmitting an indication that the UECS is capable of full-duplex communication to a network entity;
receiving, from the network entity, a resource grant for a target UE for the UECS;
receiving uplink data to transmit to the network entity;
receiving, from the first subset of UEs, demodulated and sampled downlink data, the demodulated and sampled downlink data jointly received by the first subset of UEs concurrently with joint transmission of modulated and coded uplink data by the second subset of UEs;
combining the samples received from each UE in the first subset of UEs; and
jointly processing the combined samples to provide decoded data using the received modulated and coded uplink data to cancel crosstalk of uplink signals for the transmitted uplink data from downlink signals for the received downlink data.
