Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives, from a network entity, after transmitting at least a first repetition of a physical uplink control channel (PUCCH) transmission according to a first repetition factor, a dynamic indication of a second repetition factor to apply for transmitting the same PUCCH transmission. The UE determines an application time of the second repetition factor based on at least a timing of a last complete or partial transmission instance of the PUCCH transmission. The UE transmits, to the network entity, one or more additional repetitions of the PUCCH transmission based, at least in part, on the determined application time of the second repetition factor.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless communications device may receive, from a second wireless communications device, a signal that is indicative of a phase-change pattern applied to communications between the first wireless communications device and the second wireless communication device by a reconfigurable intelligent surface reflecting the communications. The first device may determine the phase-change pattern from the signal. The first device may transmit a message to the second wireless communications device, wherein at least one of a content or a transmission property of the message is based at least in part on the phase-change pattern.

Abstract: Methods, systems, and devices for wireless communication are described to support phase continuity in uplink transmissions within a bundle interval. In a first example, a user equipment (UE) may determine bundle intervals for an uplink channel transmission based on a transmission time interval (TTI) format pattern and a bundle size. Bundle intervals may start on a next available uplink TTI after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In a second example, the UE may use frequency resources for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval. In a third example, the UE may not bundle some repetitions of the uplink channel transmission in a same bundle interval, and may use different frequency resources for the repetitions, based on one or more phase continuity rules.

Abstract: Methods, systems, and devices for codebook-based beamforming considerations for reconfigurable intelligent surfaces (RISs) are described. For example, an RIS may transmit, to a first wireless device, an indication of a capability of using different types of precoders for generating a codebook for the RIS for redirecting wireless signals. The codebook may include codewords associated with weights for respective elements of the RIS. In some cases, the RIS may receive, from the first wireless device, a type of precoder for generating the codebook. As such, the RIS may adjust one or more elements using the weights for the respective elements based on receiving the indication and in accordance with training a communication link between the first wireless device and a second wireless device via the plurality of elements. In some examples, the RIS may receive, from the first wireless device, an index corresponding to a codeword.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to identify a first set of scheduled transmissions to be received using a first set of time-frequency resources, where reference signals of the first set of transmissions may be bundled according to a first reference signal bundling pattern. The UE may identify a second scheduled transmission to be received using a second set of time-frequency resources that overlaps with the first set of resources. The UE may determine a second reference signal bundling pattern for bundling the reference signals received in the first set of transmissions. For example, the UE may modify the first reference signal bundling pattern to determine the second reference signal bundling pattern. The UE may receive the second scheduled transmission and the first set of scheduled transmissions according to the second reference signal bundling pattern.

Abstract: Certain aspects of the present disclosure provide techniques for repetition cancellation in full duplex communications. A method of wireless communication includes receiving scheduling information from a base station, wherein: the scheduling information schedules transmission of a plurality of uplink channel repetitions in a plurality of slots, the plurality of uplink channel repetitions is associated with a first sequence of redundancy versions (RVs), each repetition in the plurality of uplink channel repetitions assigned a different RV in the first sequence of RVs, and the plurality of slots include at least one full duplex slot comprising an uplink subband for uplink transmissions and a downlink subband for downlink transmissions; receiving an indication to cancel one or more repetitions of the plurality of uplink channel repetitions scheduled by the scheduling information; and taking one or more actions related to transmitting one or more remaining non-canceled repetitions of the plurality of UL channel repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message indicating that a configuration for a time restriction is disabled for the UE, such that the UE may measure one or more resources transmitted from a network entity with respect to a reference resource. The UE may receive a second message indicating that the UE is to measure one or more resources transmitted by a network entity at a first of multiple transmit power levels, the one or more resources transmitted before the reference resource, and the reference resource associated with one of the multiple transmit power levels. The UE may perform a first average measurement of the one or more resources and transmit a first report indicating the first average measurement, where the UE performs the average measurement of the one or more resources based on the second message.

Abstract: A method of wireless communication at a user equipment (UE) includes receiving, from a network node, a message indicating slots for transmitting a transport block on a physical uplink shared channel (PUSCH). The method also includes segmenting the transport block into code blocks. The method further includes encoding the code blocks to produce encoded code blocks. Each code block may be encoded at a coding path from a group of coding paths associated with a coding chain. The method still further includes transmitting the encoded code blocks in the slots on the PUSCH.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device may receive first control signaling indicating a channel state information (CSI) reporting configuration for a set of channel state information reference signal (CSI-RS) resources that correspond to a first number of antenna ports for the set of CSI-RS resources. The communication device may receive second control signaling indicating an antenna port configuration for a second number of antenna ports that is less than the first number of antenna ports. The second number of antenna ports may correspond to CSI-RS transmissions. The communication device may transmit feedback information based on the first control signaling and the second control signaling.
