Abstract: Aspects of the present disclosure provide systems and methods for assigning one or more user equipments (UEs) at one or more corresponding starting positions of multiple slots to perform channel access procedures, such as listen before talk (LBT) procedures in New Radio unlicensed band (NR-U) sidelink communications. The network entity may indicate, to a UE, a starting position in a multi-opportunity grant (e.g., a DCI scheduling multiple slots). The network entity may multiplex different transmitter UEs with different starting positions. If the channel accessing procedure is successful, the transmitter UE with the earliest starting position than the rest may block the rest of the transmitter UEs. In some cases, starting position hopping may be used so that the multiple UEs may have different priority at different slots. In some cases, the DCI may include LBT parameters that are inherited from NR-U uplink transmission configurations.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive, from a network entity, a first sidelink grant for a transmission between the first UE and a second UE; communicate the transmission according to the first sidelink grant to the second UE; determine initiation of a sidelink round trip timer subsequent to communicating the transmission to the second UE; and initiate an inactive mode for the first UE based on a second grant not being received from the network entity before completion of a duration of a sidelink retransmission timer that was initiated upon completion of a duration of the sidelink round trip timer, the first UE being configured out of an ON duration of a discontinuous reception (DRX) cycle, and an inactivity timer expiring before completion of the duration of the sidelink retransmission timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive a data packet associated with a timing parameter. The IAB may insert a time stamp into the data packet, based at least in part on the timing parameter, the time stamp associated with a reference time that is known among one or more additional IAB nodes within a path associated with the data packet. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a logged measurement configuration that defines an event for event triggered measurement logging, wherein the event is associated with a radio access technology (RAT)-specific coverage hole or a frequency specific coverage hole. The UE may perform, based at least in part on the logged measurement configuration, measurement logging based at least in part on an occurrence of the event associated with the RAT-specific coverage hole or the frequency specific coverage hole. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatuses for low latency handover between secondary nodes (SNs). In one aspect, a user equipment (UE) may receive a configuration for a plurality of SNs, receive a command to communicate via an SN of the plurality of the SNs, and determine a handover procedure that is to be used to establish a connection with the SN. The handover procedure may be a random access channel (RACH)-less or a two-step RACH procedure and is determined to be used based on a determination that uplink time synchronization is established with the SN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform radio link monitoring (RLM) reference signal measurements on a primary secondary cell (PSCell) while the UE is operating in a secondary cell group (SCG) deactivated state. The UE may perform beam failure detection (BFD) reference signal measurements while the UE is operating in the SCG deactivated state. The UE may transmit, to a master node associated with a master cell group (MCG), an SCG failure information message based at least in part on one of: a PSCell radio link failure (RLF) detection based at least in part on the RLM reference signal measurements, or a BFD based at least in part on the BFD reference signal measurements. Numerous other aspects are described.

Abstract: Techniques and apparatus for a resource pool configuration for multiple bits physical sidelink feedback channel (PSFCH) are described. An example technique includes receiving a plurality of transmissions from a user equipment (UE) on a plurality of sidelink subchannels. At least one resource set for transmitting feedback corresponding to the plurality of transmissions is determined, based on at least one of the plurality of transmissions. Feedback corresponding to the plurality of transmissions is transmitted using the at least one resource set. Another example technique includes sending a plurality of transmissions to a UE on a plurality of sidelink subchannels and monitoring for feedback corresponding to the plurality of transmissions, based on a codebook size associated with the feedback.

Abstract: Methods, systems, and devices for providing feedback about radio link failure (RLF) events that includes information about directional beams. A user equipment (UE) may experience an RLF event and lose connectivity with a network. After the UE reestablish a radio resource control (RRC) connection with the network, the UE may transmit an RLF report that include information about directional beams, information about a master node and a secondary node in a dual-connectivity procedure, information associated conditional handover procedures, or information about service time interruptions, or a combination thereof. One or more base stations may be configured to transmit at least portions of the information in the RLF report to other base stations as part of a message that may be an example of an RLF indication or a handover report. The message may be transmitted over an X2 interface or an Xn interface.
