Abstract: Wireless communications systems and methods related to hybrid in-band same-frequency full-duplex (SFFD) and frequency-offset-frequency full-duplex (FD) wireless communication are provided. A user equipment (UE) transmits first data to a base station (BS) over a first frequency band while receiving second data from the BS the first frequency band responsive to a first pathloss between the UE and the BS satisfying a threshold for an SFFD operation. The UE transmits third data to the BS over a second frequency band while receiving fourth data from the BS over a third frequency band that is distinct from the second frequency band according to an offset-frequency FD operation responsive to a second pathloss between the UE and the BS failing to satisfying the threshold.

Abstract: Systems and methods for providing indications about the TX RF non-linear impairments are disclosed. In accordance with some implementations, a first device (UE or base station) estimates EVM indications for the signal and determines if the EVM indications is above a threshold. The first device may transmit the estimated TX non-linearity indications math as AM-AM, AM-PM, Volterra coefficients, and/or other performance metrics to a second device, that transmitted the signal, when it is determined that the EVM indications is above the threshold. Systems and methods for wireless communication impairment correction are also disclosed wherein, in accordance with some implementations, a first device receives estimated TX non-linearity indications such as AM-AM, AM-PM, and/or Volterra coefficients from a second device and performs non-linear correction of a transmit signal for the second receiver device based at least in part on the EVM indications. Other aspects, embodiments, and features are also claimed and described.

Abstract: An apparatus (e.g., a wireless device) includes an antenna array and a separate antenna. The antenna array includes a plurality of antenna elements having a first antenna beam. The separate antenna includes an antenna element having a second antenna beam. The antenna element of the separate antenna is separate from the antenna elements of the antenna array. The antenna array and the separate antenna are active at different times in an operational mode. The antenna array may transmit and the separate antenna may be inactive in a transmit mode. The separate antenna may receive and the antenna array may be inactive in a receive mode. The antenna array may receive and the separate antenna may transmit in a test mode. Alternatively, the antenna array may transmit and the separate antenna may receive in the test mode.
