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. 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: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) or a base station may select a sequence from a set of sequences for conveying a payload including a set of bits. A length of the selected sequence may be based on a number of time periods for conveying the payload and a number of frequency tones for conveying the payload. The communication device may apply an interleaving function to the selected sequence to generate an interleaved sequence, and transmit the payload including the set of bits using the interleaved sequence. Likewise, the communication device may receive the payload including the set of bits using an interleaved sequence, and apply an interleaving function to de-interleave the interleaved sequence to generate a selected sequence. The communication device may thereby decode the payload based on the selected sequence.

Abstract: Wireless communication devices, systems, and methods related to power saving, including during connected mode operation and for extended reality (XR) data communications with or without discontinuous reception (DRX), are provided. For example, a method of wireless communication can include receiving, while in a connected mode, a configuration based on data traffic for the wireless communication device, the configuration indicating: a first zone associated with a first set of operating parameters for the wireless communication device; and a second zone associated with a second set of operating parameters for the wireless communication device, the second set of operating parameters being different than the first set of operating parameters; operating in the first zone with the first set of operating parameters to monitor for a first downlink communication signal; and operating in the second zone with the second set of operating parameters.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may determine to change a first slot format used when operating in a half-duplex mode based on a traffic pattern or a channel quality, or both, and may transmit a request to change the slot format to a base station. The request may include information relating to a slot format based on the traffic pattern or the channel quality, or both, such as an explicit indication of a slot format or a request for a different resource distribution between uplink symbols, downlink symbols, or flexible symbols, or any combination thereof. The base station may receive the request to change the slot format and may transmit an indication of a second slot format to the UE based on the request. The base station and the UE may communicate using the second slot format.

Abstract: Methods, systems, and devices for wireless communications are described. A method of wireless communication at a user equipment (UE) is described that may include receiving a data packet transmission over a wireless channel from a base station. The method may further include determining a set of intrinsic log likelihood ratios (LLRs) based at least in part on the data packet transmission and determining an accumulated capacity for the wireless channel based at least in part on the set of intrinsic LLRs. The method may also include determining a channel quality indicator index or a transmission rank for the wireless channel based at least in part on the accumulated capacity and transmitting a feedback message that indicates the channel quality indicator index or the transmission rank for the wireless channel to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a transmission power for a synchronization signal block (SSB) transmission by a base station, the indicated transmission power different than a default transmission power for SSB transmissions by the base station. The UE may determine a received power with which the SSB transmission is received at the UE. The UE may receive one or more downlink transmissions from the base station based at least in part on the received power for the SSB transmission and a difference between the default transmission power and the indicated transmission power for the SSB transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station in a full duplex mode, a first downlink transmission associated with a spatial filter. The UE may decode the first downlink transmission according to a default transmission configuration indicator (TCI) state that indicates the spatial filter. The default TCI state may be based at least in part on a first active TCI state for the full duplex mode. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may interleave a signal, that is to be transmitted using discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (DFT-s-OFDM), and a negative of the signal to obtain an interleaved signal prior to performing a DFT on the interleaved signal. The UE may transmit a DFT-s-OFDM signal that is based at least in part on the interleaved signal. Numerous other aspects are provided.
