Abstract: Techniques for processing of symbols (e.g., orthogonal frequency division multiplexing (OFDM) or single carrier-frequency division multiple access (SC-FDMA) symbols) provide enhanced out-of-band (OOB) suppression of the symbols and also provide reduced inter-symbol interference (ISI) between a symbol and a subsequent symbol. Multiple frequency tones of a symbol may be divided into two or more subsets of tones. For example, subsets of tones associated with a head portion or a tail portion of an OFDM symbol may be processed with a relatively long weighted overlap-add (WOLA) weighting length or filtering length, and a subset of tones associated with a center portion of the OFDM symbol may be processed with a relatively short WOLA weighting length or filtering length. Such heterogeneous processing of tones within a symbol may provide enhanced inter-channel interference (ICI) and improved OOB suppression and also provide reduced ISI for the center tones of the symbol.

Abstract: Certain aspects relate to techniques for z-axis rotation estimation for compensating signaling transmitted between two or more nodes over a wireless channel where an antenna array of at least one of the nodes is misaligned about the z-axis relative to another node. For example, a transmitting node may transmit pilot signals defined by phase shifts to provide a receiving node with a basis for estimating the angle of rotation by which the antenna arrays are misaligned. The transmitting node may then take remedial action to address the misalignment based on the estimation.

Abstract: In an aspect, a first BS measures a SRS-P associated with a RTT measurement procedure between a UE and a second base station, and reports measurement information based on the measurement of the SRS-P. In another aspect, a device (e.g., UE, BS, LMF, etc.) obtains the measurement information along with measurement information based on measurements at the UE and the second base station, and determines a positioning estimate of the UE based on the first, second and third measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink control information (UCI) payload satisfies a threshold size condition. The UE may map the UCI payload to an uplink control sequence. The UE may transmit a physical uplink control channel (PUCCH) that include the uplink control sequence to a base station. The uplink control sequence may be representative of the UCI payload. The base station may receive the PUCCH that includes the uplink control sequence from the UE. The base station may also determine the UCI payload by associating the uplink control sequence with a corresponding sequence index of the one or more sets of uplink control sequences.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: In an aspect, a first base station (e.g., Rx gNB) receives, from a radar controller, a configuration of UL T-F resources for the first base station to receive at least one radar signal from a second base station. The first base station further determines power control parameter(s) associated with the at least one radar signal, at least one UL transmission, or a combination thereof. The first base station performs, based on the power control parameter(s), action(s) to mitigate impact by the at least one radar signal to the at least one UL transmission, or by the at least one UL transmission to the at least one radar signal, or a combination thereof. The first base station measures the at least one radar signal on the set of UL T-F resources in accordance with the configuration.
