UE cooperative reception and cooperative transmission for quality of service demanding applications

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• transmit, to a base station, a report indicating that a cooperative reception group supports one or more downlink transmit beamforming techniques, wherein the cooperative reception group includes the UE and one or more other UEs connected to the UE over an out-of-band link;
• determine, based at least in part on the one or more downlink transmit beamforming techniques supported by the cooperative reception group, a downlink transmit precoder associated with relaxed beamforming nulling;
• receive a downlink transmission from the base station and one or more decoded bits associated with the downlink transmission from the one or more other UEs in the cooperative reception group;
• and
• decode the downlink transmission based at least in part on the downlink transmit precoder and the one or more decoded bits received from the one or more other UEs in the cooperative reception group.

A method of wireless communication performed by a user equipment (UE), comprising:

• transmitting, to a base station, a report indicating that a cooperative transmission group supports one or more uplink transmit beamforming techniques, wherein the cooperative transmission group includes the UE and one or more other UEs connected to the UE over an out-of-band link;
• determining, based at least in part on the one or more uplink transmit beamforming techniques supported by the cooperative transmission group, a transmit precoder to be used for an uplink transmission;
• and
• transmitting, jointly with the one or more other UEs in the cooperative transmission group, the uplink transmission to the base station based at least in part on the transmit precoder.
