Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink carrier aggregation with cross-carrier feedback are disclosed herein. An example method for wireless communication at a first wireless device includes receiving, from a second wireless device, a first sidelink message including a first transport block (TB) on a first carrier. The example method also includes generating a first Hybrid Automatic Repeat Request (HARQ) feedback for the first TB. The example method also includes determining a first feedback carrier to transmit cross-carrier feedback. The example method also includes mapping the first HARQ feedback for the first TB to the first feedback carrier, the first feedback carrier being different than the first carrier. The example method also includes transmitting the first HARQ feedback on the first feedback carrier to the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Abstract: Certain aspects of the present disclosure generally relate to techniques for selecting a base graph to be used for wireless communications. Selection can be based on a variety of factors. A base graph can be used to derive a low-density parity-check (LDPC) code used for encoding a retransmission of an original transmission. An exemplary method generally includes selecting, based on a modulation and coding scheme (MCS) and a resource allocation (RA) for transmitting a codeword, a base graph (BG), from which to derive a low density parity check (LDPC) code for use in encoding data bits in the codeword (e.g., encoding data bits of a bitstream such that some redundant bits are included in the codeword), encoding the data bits to generate the codeword using the LDPC code derived from the selected BG, and transmitting the codeword using the MCS via resources of the RA.

Abstract: Certain aspects of the present disclosure provide techniques for requesting inter-UE coordination messages for sidelink communications. In some cases, a method for wireless communications by a first user equipment (UE), include sending a first sidelink transmission to at least one second UE to trigger the second UE to transmit a report regarding sidelink resource availability and monitoring for a second sidelink transmission from the second UE after sending the first sidelink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit, to a receiver UE, a request for sensing information that includes an indication of one or more transmit beam directions. The UE may receive, from the receiver UE based at least in part on the indication of the one or more transmit beam directions, sensing information associated with a beam of a plurality of beams configured for communications between the transmitter UE and the receiver UE. Numerous other aspects are described.

Abstract: A first device may communicate an SL NC TB with a second device. At least one of the first device and the second device may be a UE. The first device may transmit, to a network entity, a first message having a first location information that indicates a movement of the UE from a first zone to a second zone. The first message may have a first location information associated with the UE. The UE may be in SL communication with a first encoder in the first zone. The network entity may obtain, from the first device, the first message. The network entity may initialize an NC handover of the UE to a second encoder of the second zone in response to the first location information indicating a movement of the UE from the first zone to the second zone.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish multiple unicast connections with multiple other UEs. The first UE may then determine individual sets of transmission parameters for each of the multiple other UEs, where the individual sets of transmission parameters may enable the first UE to receive transmissions from the multiple other UEs on a same set of time and frequency resources via a spatial division multiplexing scheme. For example, each of the individual sets of transmission parameters may include a transmission schedule adjustment, a transmit power, a transmit time, an indication of the time and frequency resources, or a combination thereof. The first UE may then transmit each of the individual sets of transmission parameters to a respective UE of the multiple other UEs.
