Abstract: Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.

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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.
