Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a relay user equipment (UE)) may establish a communication link, where the communication includes establishing a communication link between a second device (e.g., a remote UE) and a base station, the communication link including a first communication link between the second device and the first device and a second communication link between the first device and the base station. The first device may receive, over the first communication link, a transmission corresponding to data stored at the second device. The first device may receive, over the second communication link, an indication of one or more resources for a relay transmission corresponding to the data stored at the second device. The first device may transmit, over the second communication link, the relay transmission over the one or more resources based on receiving the sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may distinguish between synchronization signal blocks (SSBs) intended for different classes of UEs. For example, a base station may transmit different SSBs in a physical broadcast channel with different configurations or parameters to indicate different UE classes, where UEs may monitor for and receive SSBs for their UE class. A UE may operate according to a UE class (e.g., New Radio (NR) Light) associated with lower bandwidths and may identify SSBs associated with this UE class to connect with a base station. The UE may identify the SSBs associated with the UE class based on a subcarrier-level offset value either implicitly or explicitly indicated to the UE. Additionally, the base station may transmit fields to indicate different parameters for subsequent communications transmitted according to the UE class.

Abstract: A user equipment (UE) may receive a first group downlink control information transmission associated with a UE group, where the first group downlink control information transmission may reference a second group downlink control information transmission (e.g., according to a pre-notification indication). The UE may determine a feedback condition for the second group downlink control information transmission and monitor for the second group downlink control information transmission. Alternatively, the UE may receive a second group downlink control information transmission referencing the first group downlink control information transmission (e.g., according to a post-confirmation indication), and the UE may determine a feedback condition for the first group downlink control information transmission. Based on the feedback condition, the UE may transmit feedback information, for example, indicating that the UE did not correctly receive the indicated group downlink control information transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a configuration of a radio link monitoring resource for a radio link that transports downlink traffic for a first type of service, the first type of service having a higher reliability specification and a lower latency specification than a second type of service offered by the base station. The UE may receive the configuration, and detect that the radio link satisfies a failure condition for the first type of service based on monitoring the RLM resource. The UE may transmit a radio link failure (RLF) indication for the first type of service to the base station based on detecting that the radio link satisfies the failure condition for the first type of service. The base station may receive the RLF from the UE, and transmit an RLF response to the UE.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station for wireless communication, associated with a first radio access technology (RAT), may generate a message to cause a user equipment to wake up from a power saving state or to reconfigure a cycle associated with the power saving state, wherein the message includes an indication that the user equipment is to wake up from the power saving state or to reconfigure the cycle; and/or transmit the message toward the user equipment via a second base station, associated with a second RAT and the user equipment, to cause the user equipment to wake up from the power saving state or reconfigure the cycle. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a group-specific radio network temporary identifier (RNTI) associated with non-orthogonal multiple access (NOMA); receive an indication of whether the group-specific RNTI is associated with contention-based NOMA or contention-free NOMA; and selectively use a group-specific multiple access (MA) signature or a UE-specific MA signature for a NOMA transmission based at least in part on the indication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access channel (RACH) procedure with a base station. The UE may receive a message configuring a RACH preamble occasion and an uplink data occasion. The message may be a radio resource control (RRC) message or a system information (SI) message. In some cases, the UE may determine if the RACH preamble occasion, the uplink data occasion, or both are restricted for cancellation based on the message. The UE may determine when to monitor a downlink control channel for dynamic scheduling based on determining which occasions are restricted for cancellation and may transmit a RACH message based on monitoring—or not monitoring—the downlink control channel for dynamic scheduling preempting a RACH occasion. In some other cases, a base station may schedule transmissions to not overlap with configured RACH occasions.

Abstract: Methods, systems, and devices for wireless communications are described for identifying a file having a set of packets that are configured to be processed together. The base station may determine a segmentation scheme for the file based on a size of the file and identify a batch of assignments for communicating the file via a batch of transmissions based on the segmentation scheme. The base station may communicate the file via the batch of transmissions with a user equipment (UE) during the batch of assignments. Additional techniques are described herein for a UE to identify that the UE is storing a file in a buffer at the UE. The UE may transmit an indication to the base station that the buffer includes the file. In some cases, the UE may indicate a size of the file.
