Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for dynamically activating and deactivating random-access channel (RACH) occasions (ROs). A base station may configure one or more ROs on which a user equipment (UE) can transmit RACH messages. If higher priority signaling (e.g., downlink signaling or uplink signaling) overlaps in time with the ROs, the base station may deactivate one or more ROs to decrease the likelihood of self-interference or cross-link interference (e.g., if the UE or the base station are operating in full duplex mode). The base station may deactivate or activate ROs by indicating indices for one or more ROs, indices for one or more synchronization signal blocks (SSBs), a pattern of ROs, some or all ROs within a time period, some or all ROs until a next downlink signal updates the RO configuration or activates ROs, or any combination thereof.

Abstract: A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device such as a user equipment (UE) may determine to transition from a first duplexing mode to a second duplexing mode, where a first communication associated with the first duplexing mode at least partially overlaps in time with a second communication associated with the second duplexing mode. Based on the overlap, the UE may identify transition information for coordinating the transition between the first duplexing mode and the second duplexing mode. Using the transition information, the UE may transition from the first duplexing mode to the second duplexing mode, and may communicate with a second wireless device, such as a base station, using the second duplexing mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode. A user equipment (UE) may detect the base station that is operating in an energy saving mode. The UE may transmit a request for the base station to transmit the RMSI to the UE, where the UE may transmit the request to the energy saving base station or to a serving base station of the UE. The UE may receive, from the base station operating in the energy saving mode and responsive to the request, a message including the remaining minimum system information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple candidate sets of physical sidelink feedback channel (PSFCH) transmissions that include hybrid automatic repeat request (HARQ) feedback for sidelink communications received from one or more peer UEs. The UE may select, from one or more of the multiple candidate sets that satisfy a PSFCH transmit power constraint, at least one candidate set that has a highest value for a utility parameter among utility parameters associated with each of the one or more candidate sets that satisfy a PSFCH transmit power constraint. The UE may transmit, on a PSFCH, the plurality of PSFCH transmissions included in the at least one candidate set in a HARQ feedback occasion. Numerous other aspects are provided.
