Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may communicate an allocation of a set of time-frequency resources of a carrier for transmission of a first codeword. The first wireless device may map a first portion of the first codeword to resource elements of a first subband of the set of time-frequency resources in a frequency-first, time-second manner and a second portion of the first codeword to resource elements of a second subband of the set of time-frequency resources in the frequency-first, time-second manner. The first portion of the first codeword may include a contiguous portion of the first codeword preceding the second portion of the first codeword. The first wireless device may transmit, within the set of time-frequency resources, the first codeword based on the mapping.

Abstract: A method for wireless communication by a user equipment (UE) includes receiving, from a network node, a group of downlink transmissions. The method also includes segmenting a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) payload into a group of segments in accordance with a segmentation configuration. The method further includes forming, for each segment of the group of segments, a first HARQ-ACK part and a second HARQ-ACK part. The method also includes jointly encoding each first HARQ-ACK part and jointly encoding each second HARQ-ACK part. The method further includes transmitting the jointly encoded first HARQ-ACK parts and the jointly encoded second HARQ-ACK parts.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating to switch from a first slot format to a second slot format. The first slot format may include symbols for reference signal transmissions and symbols for data transmissions. Thus, the first slot format may be a full-TDM slot that supports time division multiplexing (TDM) reference signals and data. The second slot format may be a hybrid TDM/frequency division multiplexing (FDM) slot or a full-FDM slot that includes at least one symbol for frequency division multiplexing (FDM) reference signals and data. Based on a capability of the UE and the control message, the UE may switch to the second slot format and communicate a reference signal in a symbol configured for FDM. That is, the reference signal may be FDMed with data according to the second slot format.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a quantity of hybrid automatic repeat request (HARQ) codebooks capable of being stored by the UE, a maximum amount of HARQ codebook data capable of being stored by the UE, or a maximum HARQ codebook size capable of being stored by the UE, and may transmit, to a network node, capability information that indicates the quantity of HARQ codebooks capable of being stored by the UE, the maximum amount of HARQ codebook data capable of being stored by the UE, or the maximum HARQ codebook size capable of being stored by the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive a message indicating a configuration or a sidelink discovery burst transmission window. The configuration may include time periods for transmitting multiple sidelink synchronization signals. The first UE may perform a channel access procedure during the sidelink discovery burst transmission window. The first UE may perform the channel access procedure for transmitting one or more of the sidelink synchronization signals according to a pattern indicated by the configuration. The pattern may be based on a quasi co-location relationship between associated pairs of the sidelink synchronization signals. The first UE may transmit the one or more sidelink synchronization signals to a second UE in accordance with the pattern indicated by the configuration.

Abstract: Certain aspects of the present disclosure provide techniques for a resource pool for cross-link interference (CLI) reference signals (RSs). A method for wireless communications by a wireless node includes selecting one or more resources from at least one resource pool comprising a plurality of resources for CLI-RSs. The method includes outputting for transmission or monitoring for one or more CLI-RS on the one or more resources.

Abstract: In an aspect, a user equipment (UE) may measure one or more positioning reference signals (PRS) transmitted by one or more transmission-reception-points (TRPs). The UE may measure one or more backscattered signals received from one or more ambient Internet-of-things (IoT) anchor devices, wherein the one or more backscattered signals correspond to the one or more PRS received at the one or more ambient IoT anchor devices.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a bundling factor, may first generate a codebook, and may then bundle a quantity of bits into a single bit according to the bundling factor (e.g., may compress the sequence of bits into a smaller, second set of bits, where each bit of the second set of bits represents a quantity of the sequence of bits equal to the bundling factor). The UE may support cross downlink control information (DCI) bundling, in which case each bundle of the sequence of bits may be based on the bundling factor, instead of being based on the DCI (e.g., a given bundle may include feedback bits corresponding to occasions of multiple grants).

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may receive a first sidelink message associated with a sidelink feedback transmission occasion and a second sidelink message also associated with the sidelink feedback transmission occasion. The UE may provide a type of feedback information via the sidelink feedback transmission occasion based on the first sidelink message and the second sidelink message both being associated with the sidelink feedback transmission occasion. The provided type of feedback information may be based on a quantity of one or more additional sidelink feedback transmission occasions subsequent to the sidelink feedback transmission occasion that are also available for transmission of either first feedback associated with the first sidelink message or second feedback associated with the second sidelink message.
