Apparatus and methods for full duplex communication

An apparatus for wireless communications, comprising:

• means for transmitting, by a first wireless communications device, a plurality of reference signals at a corresponding plurality of transmit power levels;
• means for receiving the plurality of reference signals at a receiver chain of the first wireless communications device;
• means for performing echo cancellation on the plurality of reference signals received at the receiver chain;
• means for determining, for each reference signal of the plurality of reference signals, a value of a first echo cancellation metric indicative of a first amount of echo cancellation achieved by performing the echo cancellation on the reference signal;
• and
• means for providing the each first echo cancellation metric, in a full duplex capability matrix that maps each transmit power level of the plurality of transmit power levels to the value of the first echo cancellation metric corresponding to each reference signal, to a scheduling entity for scheduling full duplex (FD) or half duplex (HD) communication resources for the first wireless communications device.

An apparatus for wireless communications, comprising:

• a processor;
• memory coupled to the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• transmit, by a first wireless communications device, a plurality of reference signals at a corresponding plurality of transmit power levels;
• receive the plurality of reference signals at a receiver chain of the first wireless communications device;
• perform echo cancellation on the plurality of reference signals received at the receiver chain;
• determine, for each reference signal of the plurality of reference signals, a value of a first echo cancellation metric indicative of a first amount of echo cancellation achieved by performing the echo cancellation on the reference signal;
• and
• provide each first echo cancellation metric, in a full duplex capability matrix that maps each transmit power level of the plurality of transmit power levels to the value of the first echo cancellation metric corresponding to each reference signal, to a scheduling entity for scheduling full duplex (FD) or half duplex (HD) communication resources for the first wireless communications device.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code comprising instructions executable to:

• transmit, by a first wireless communications device, a plurality of reference signals at a corresponding plurality of transmit power levels;
• receive the plurality of reference signals at a receiver chain of the first wireless communications device;
• perform echo cancellation on the plurality of reference signals received at the receiver chain;
• determine, for each reference signal of the plurality of reference signals, a value of a first echo cancellation metric indicative of a first amount of echo cancellation achieved by performing the echo cancellation on the reference signal;
• and
• provide each first echo cancellation metric, in a full duplex capability matrix that maps each transmit power level of the plurality of transmit power levels to the value of the first echo cancellation metric corresponding to each reference signal, to a scheduling entity for scheduling full duplex (FD) or half duplex (HD) communication resources for the first wireless communications device.
