Abstract: A method for refining radio frequency communication link quality in a communication system may include obtaining measured beam pair quality data between one or more transmit beams and one or more receive beams during a measurement time interval. Beam pair quality data may be measured using an antenna array in which each antenna has a weight. A combination of antenna weights defines an antenna array configuration or beam. The method may further include, during a communication time interval following the measurement time interval, adjusting an antenna weight combination in response to the measured beam pair quality data and a previous antenna array configuration, to define a next antenna array configuration. A transmitter and receiver may communicate information using the next antenna array configuration during the communication time interval. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems and methods for communicating in a wireless network using a first radio access technology (RAT) and an assisting RAT are disclosed. A first connection can be established with a user equipment (UE) using the first RAT, and a second connection can be established with the UE using an assisting RAT. A timing of the first connection can be synchronized based at least in part on a timeline of the assisting RAT, and a neighboring access point can be collaborated with in communicating with a UE over at least the first connection.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, the first wireless device may transmit, to a second wireless device, a control message indicating a set of pre-equalization transmission schemes supported by the first wireless device for receipt of messaging pre-equalized by the second wireless device. The first wireless device may transmit a measurement report that indicates a measurement of a wireless channel between the first wireless device and the second wireless device, where the measurement may be a signal-to-interference and noise (SINR) measurement. The first wireless device may receive a control signal indicative of a first pre-equalization transmission scheme to be used by the second wireless device for pre-equalization based at least in part on the set of pre-equalization transmission schemes and the measurement. The first wireless device may receive, via the wireless channel, a downlink message pre-equalized in accordance with the first pre-equalization transmission scheme.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) transmitting a capability message indicating a capability of the UE to support a positioning scheme for one or more reference signals within a precoding resource block group for a channel estimation procedure, receiving, based on the capability message, a control signal indicating a frequency allocation for the one or more reference signals for the channel estimation procedure, the frequency allocation for the one or more reference signals being based on the positioning scheme supported by the UE, receiving the one or more reference signals for the channel estimation procedure in accordance with the frequency allocation, and performing the channel estimation procedure using the one or more reference signals based on the precoding resource block group associated with the channel estimation procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first downlink transmission. The UE may receive an uplink transmission that includes channel state information including an indication of one or more samples of the first downlink transmission, wherein the one or more samples, before reception of the uplink transmission, are unprocessed for a channel estimation. The UE may transmit a second downlink transmission in accordance with the channel estimation that is based at least in part on the one or more samples. Numerous other aspects are described.
