Abstract: A method of wireless communications by a transmitting sidelink user equipment (UE) includes transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB). The SL-SS has an SL-SS pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols, which may be zero PSBCH symbols. The method also includes receiving transmission in accordance with the SL-SS. The SL-SS may be transmitted at a time and/or frequency different from a legacy SL-SS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of at least two time division duplex (TDD) patterns. The UE may communicate based at least in part on a first pattern of the at least two TDD patterns. The UE may communicate based at least in part on a second pattern of the at least two TDD patterns, based at least in part on a timer, associated with the first pattern, expiring. In some aspects, the UE may further communicate based at least in part on a third pattern of the at least two TDD patterns. The UE may use the third pattern before the timer associated with the first pattern expires or based at least in part on expiry of an additional timer associated with the second pattern. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for wireless communication devices for tone reservation. A user equipment (UE) receives an indication of one or more peak-reduction tone (PRT) resources for a transmission of one or more signals for a base station. The UE transmits a first signal to the base station on an uplink. The UE transmits a second signal to a relay entity on a sidelink for reception by the base station. The second signal is transmitted on the sidelink utilizing the one or more PRT resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may communicate during asynchronous slots in accordance with a set of communication parameters determined from a handshake procedure performed with a second base station. For example, based on a change to a slot type of a slot to an asynchronous slot, the first base station and the second base station may perform the handshake procedure to determine the set of communication parameters and may communicate one or more messages during the slot in accordance with the set of communication parameters. Additionally, or alternatively, a user equipment (UE) may transmit a sounding reference signal (SRS) associated with a transmission configuration indicator (TCI) state based on a slot type of a first slot in which the UE transmits the SRS and a reference signal received in a second slot having the slot type.

Abstract: A UE may identify slots to transmit and/or receive information related to one or more HARQ processes in frame structure that includes both sub-band full duplex slot types and time division duplex slot types. Based on a first slot used for control information, a UE can identify a second slot for PUSCH or PDSCH communication based on an offset between the first slot and the second determined by calculating slot offsets (e.g., based on parameters received from a base station). In some aspects, a UE may exclude certain slot duplex types (e.g., SBFD or TDD) when calculating slot offsets. In some aspects, a UE may calculate slot offsets differently for different HARQ processes corresponding to one frame. In some aspects, slot offset behaviors may be based on priority of information associated with a HARQ process.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration signaling indicating a parameter for generating a plurality of first orthogonal matrices, wherein the plurality of first orthogonal matrices are based at least in part on a second orthogonal matrix, and wherein a size of the second orthogonal matrix is based at least in part on a number of one or more time periods configured for conveying a payload and a number of one or more frequency tones configured for conveying the payload. The UE may generate a plurality of codebooks corresponding to the plurality of first orthogonal matrices. The UE may transmit a first portion the payload using a first sequence from a first codebook of the plurality of codebooks and a second portion of the payload using a second codebook of the plurality of codebooks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Wireless communications systems may configure a subset of allocated resources (e.g., one or more resource elements (REs) of one or more allocated resource blocks (RBs)) as peak reduction tones (PRTs) for a peak-cancelation signal. For instance, wireless communications systems may configure a fixed PRT allocation based on a Costas array. In some examples, each column of a Costas array may correspond to a RB of a set of allocated resources. A transmitting device may thus identify one or more PRT REs based on the Costas array and a mapping of allocated RBs to the columns of the Costas array. For instance, a transmitting device may identify a pattern of PRT REs to use for a peak-cancellation signal based at least in part on a configured Costas array (e.g., where the peak-cancellation signal may reduce peaks of a corresponding data signal to ultimately reduce peak-to-average power ratio (PAPR) of a transmission).

Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.
