    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit, to another wireless node, information related to one or more properties of a first antenna array associated with the wireless node. The wireless node may receive, from the other wireless node, information related to one or more properties of a second antenna array associated with the other wireless node. The wireless node may communicate with the other wireless node over a wireless link using one or more beams associated with an operating frequency, wherein the operating frequency is based at least in part on the one or more properties of the first antenna array and the one or more properties of the second antenna array. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may generate a first time-domain reference signal sequence of a first sequence length, and may truncate the first sequence length to a second sequence length and may append a header portion and a tail portion to the truncated first time-domain reference signal sequence. The transmitting device may perform a discrete Fourier transform (DFT) on the truncated first time-domain reference signal sequence to generate a frequency-domain reference signal sequence associated with a phase constant, and may perform an inverse fast-Fourier transform (IFFT) on the result of the DFT. The transmitting device may then transmit the result of the IFFT to a receiving device, which may further process the signal by performing a fast-Fourier transform (FFT), dividing by the phase constant, and taking the conjugate of the received sequence.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a transmitting device may support receiver-specific network coding redundancy techniques. For example, a transmitting device may select a receiver-specific redundancy configuration for transmission to a particular receiver based on a quality of a link between the transmitting device and the receiving device. The transmitting device may select or calculate a user-specific redundancy for the link based on a received packet loss probability report, or may select the preferred redundancy configuration as indicated in a request received from the receiving device, or may network encode and transmit one or more initial transmissions according to a default redundancy configuration and increment or decrement the default redundancy based on feedback from the receiving device.

    Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for signaling mechanisms associated with reporting information associated with multiple beam failure indicator (BFI) types via a beam failure detection (BFD) report. In some aspects, a user equipment (UE) may measure a periodic reference signal as part of a BFD procedure and may report a BFI if the UE measures that the reference signal fails to satisfy a threshold signal strength or quality. The UE may further detect or classify each reported BFI as one of multiple BFI types and may store information associated with respective numbers of the multiple BFI types in accordance with the detection or classification. In scenarios in which the UE declares beam failure, the UE may transmit a BFD report including the information associated with the respective numbers of the multipole BFI types.

    Abstract: Methods, systems, and devices for wireless communications are described. A network controlled repeater may transmit a capability indication of the wireless device to a network entity. The capability indication of the wireless device may indicate a latency associated with processing communications. The network entity may transmit an indication of multiple monitoring occasions during a discontinuous reception mode of the wireless device, and a set of parameters associated with the multiple monitoring occasions. Each monitoring occasion of the multiple monitoring occasions may be associated with at least one of a different periodicity, length, or offset. The wireless device may periodically monitor for the communications in accordance with the multiple monitoring occasions.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a network node, control signaling indicating a first downlink bandwidth part (BWP) and a first uplink BWP, or a first downlink sub-band and a first uplink sub-band, or both, for performing sub-band full-duplex (SBFD) communications. The UE may receive, from the network node, a downlink control information (DCI) message indicating to switch to a second downlink BWP and a second uplink BWP, or to switch to a second downlink sub-band and a second uplink sub-band, or both. The UE may then perform full-duplex communications with the network node within the second downlink BWP and the second uplink BWP, or within the second downlink sub-band and the second uplink sub-band, or both.
