Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may transmit a first transmission of a transport block to a user equipment (UE). The UE may decode the received transport block and may receive control signaling indicating that a second wireless device is to transmit a second transmission of the transport block based on decoding the transport block. The UE may perform interference cancellation for the second transmission of the transport block from the second wireless device based on receiving the control signaling and may receive a third transmission based on performing the interference cancellation, where a first resource of the second transmission overlaps in time, frequency, or both with a second resource of the third transmission.

Abstract: Wireless communications systems and methods related to dynamically triggering aperiodic CSI reporting are disclosed. A UE may determine whether a condition is satisfied for triggering upon receipt of a signal from a BS. The condition may be based on a decoding status of the signal. In some examples, the UE may explicitly request a CSI resource signal (e.g., CSI-RS, CSI-IM, or both) from the BS when the condition is met. The explicit request may be included in a modified ACK/NACK field, regardless of whether an ACK or NACK is transmitted. The BS may respond with a CSI resource signal. In other examples, the BS may wait to respond with a CSI resource signal until a threshold number of requests are received from the UE. In other examples, the BS may track a number of NACKs from the UE instead of relying upon an explicit request.

The UE may transmit to one or more sidelink UEs, sidelink control information that may include a reservation of a set of mini-slots of a first slot of the multiple slots, where the quantity of the set of mini-slots satisfies the threshold quantity of mini-slot reservations.

The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to techniques, methods, devices, systems, and non-transitory computer readable medium for generating codebooks for reconfigurable intelligent surfaces (RIS) s. For example, a RIS controller generates a codebook for a RIS by computing weights using a discrete Fourier transform (DFT) function or a fractional Fourier transform (FrFT) function, based on reference signals (RSs) transmitted by a transmitter. The weights correspond to the RIS elements or a subset of the RIS elements. In some aspects, the computation of the weights may include oversampling factors that allow for a higher resolution of the weights and improved search for an optimal precoding setting. Different sets of weights may be used for different incoming beams. The RIS controller may be trained with a pair of transmitter and a receiver to identify/generate the codebook for an optimized set of weights under specific situations.

The first radio of the UE may be a main radio. The second radio of the UE may be a wakeup receiver.

The network entity may transmit an indication that uplink channel selection by the UE is enabled. The UE may select a first uplink channel from the multiple uplink channels allocated by the scheduling information based on the indication that uplink shared channel selection is enabled. The UE may transmit an uplink message via the first uplink channel, and the UE may refrain from transmitting via other uplink channels of the multiple uplink channels allocated by the scheduling information based on selecting the first uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a configuration of multiple resource patterns for one or more user equipments (UEs) to use for transmission of sidelink signals over a quantity of transmission time intervals (TTIs) (e.g., sub-slots) within a slot. For example, a UE may determine a resource pattern to use for transmitting sidelink signals based on an assignment from a network entity, an initial frequency offset, information included in control signaling, or any combination thereof. In some examples, the UE may transmit, via the sidelink channel, an indication of the resource pattern used by the UE, such that other UEs in the system may determine the resource pattern used by the UE. The UE may transmit a sidelink signal in accordance with the resource pattern, while other UEs may use other resource patterns for sidelink transmissions within the same slot.
