Full-duplex for line-of-sight multiple-input multiple-output

A method for wireless communications at a first wireless device, comprising:

• receiving, from a second wireless device, a message indicating a capability of the second wireless device to support full-duplex line-of-sight (LOS) multiple-input multiple-output (MIMO) communications;
• transmitting, based at least in part on receiving the message from the second wireless device, control signaling indicating an uplink channel resource allocated for one or more uplink communications, a downlink channel resource allocated for one or more downlink communications, a first set of one or more LOS MIMO transmission modes to be used for the one or more uplink communications, and a second set of one or more LOS MIMO transmission modes to be used for the one or more downlink communications, wherein the uplink channel resource at least partially overlaps with the downlink channel resource in time, frequency, or both;
• and
• communicating the one or more uplink communications via the uplink channel resource in accordance with the first set of one or more LOS MIMO transmission modes and the one or more downlink communications via the downlink channel resource in accordance with the second set of one or more LOS MIMO transmission modes based at least in part on the control signaling.

An apparatus for wireless communications at a first wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• one or more instructions stored in the memory and executable by the processor to cause the apparatus to, based at least in part on the one or more instructions:
• transmit, to a second wireless device, a message indicating a capability of the first wireless device to support full-duplex line-of-sight (LOS) multiple-input multiple-output (MIMO) communications;
• receive control signaling from the second wireless device in response to the message, the control signaling indicating an uplink channel resource allocated for one or more uplink communications, a downlink channel resource allocated for one or more downlink communications, a first set of one or more LOS MIMO transmission modes to be used for the one or more uplink communications, and a second set of one or more LOS MIMO transmission modes to be used for the one or more downlink communications, wherein the uplink channel resource at least partially overlaps with the downlink channel resource in time, frequency, or both;
• and
• communicate the one or more uplink communications via the uplink channel resource in accordance with the first set of one or more LOS MIMO transmission modes and the one or more downlink communications via the downlink channel resource in accordance with the second set of one or more LOS MIMO transmission modes based at least in part on the control signaling.
