Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive pilot signaling associated with inphase and quadrature (IQ) mismatch estimation for a set of antennas of a base station. The UE may measure pilot signals for each of the set of antennas based on a pilot signal pattern of the pilot signaling, and calculate an estimation of an IQ mismatch for each antenna of the set of antennas of the base station based on measuring the pilot signals. The base station may receive, from the UE, a report including an indication of the estimation of the IQ mismatch for each antenna of the set of antennas of the base station based on the pilot signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message from a base station indicating a modulation and coding scheme (MCS) associated with an uplink transmission, a number of layers associated with the uplink transmission, or both. The UE may determine to adjust (for example, reduce) a first number of bits based on the MCS, the number of layers, or both. The first number of bits may include an effective number of bits (ENOB) supported at a digital-to-analog converter (DAC) of the UE, a number of bits (NOB) supported at a transmission front end (TxFE) component of the UE, or both. The UE may transmit the uplink transmission to the base station according to the adjusted first number of bits.

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: Coherence based pre-decoding pruning for control channels in wireless communication systems is discussed. Data is received on at least one channel resource of a plurality of channel resources. In addition, the determining of a plurality of channel coherence metrics is discussed, where a channel coherence metric for a channel resource indicates coherence information between channels on which the plurality of carriers associated with the channel resource operate. Additionally, the determining of one or more channel resources to search for data to be decoded based, at least in part, on the plurality of channel coherence metrics is also discussed. Other aspects, embodiments, and features are also claimed and described.
