Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface using a set of precoder configurations. In some aspects, the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with configuring the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflecting signals. The UE may additionally transmit, to the base station via the reconfigurable surface, a feedback message including an indication of at least one precoder configuration of the set of precoder configurations based on receiving the set of reference signals. The UE may then receive, from the base station via the reconfigurable surface, a downlink transmission based on transmitting the feedback message.

Abstract: Wireless communication devices, systems, and methods related to bundling of uplink communication signals under timing advance (TA) conditions are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from a base station, a timing advance (TA), wherein the TA is scheduled to be implemented by the user equipment at a first time, the first time being after a start of a first uplink communication of a group of bundled uplink communications scheduled with phase coherence and before a start of a second uplink communication of the group of bundled uplink communications; determining whether to implement the TA at the first time or a second time, the second time being after transmission of the second uplink communication; and implementing the TA based on the determining.

Abstract: Methods, systems, and devices for wireless communications are described that provide for indication of channel state information (CSI) for multiple CSI codebooks associated with multiple different sets of antenna ports, where CSI parameters for one or more of the codebooks are reported as differential values relative to reported values of another of the codebooks. A user equipment (UE) may receive a CSI report configuration that includes a set of CSI resources and multiple codebooks for multiple different sets of antenna ports. The UE may identify a first set of CSI parameters associated with a first codebook, and may identify a second set of CSI parameters associated with a second codebook. The UE may transmit a CSI report that includes the first set of CSI parameters and a set of differential CSI parameters that indicate a difference between the first and second sets of CSI parameters.

Abstract: Methods, systems, and devices for wireless communications are described in which a network entity may use a lower power sleep procedure to reduce power consumption, and monitor for a wake-up signal (WUS) from at least one user equipment (UE) during configured WUS occasions. The WUS from one or more UEs may provide information of one or more attributes of data traffic that is present at a transmit buffer of the one or more UEs. A WUS configuration may be provided from a network entity that allows the selection of a particular WUS to indicate one or more attributes of the data traffic at the UE. The WUS may convey information such as buffer status, power headroom, a priority of traffic, latency targets of the traffic, or any combinations thereof. The WUS may also give an indication of a requested duration of an active mode at the network entity.

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.
