Certain aspects of the present disclosure provide techniques for signaling a user equipment (UE) to put a sidelink (SL) component carrier (CC) into dormancy or take the SL CC out of dormancy, such as mode 1 or mode 2 sidelink communications. In one example, a method performed by a UE includes receiving an indication to put a first CC into dormancy; and putting an SL CC into a dormant state in response to the indication. In another example, a method includes transmitting an indication that the first UE will put an SL CC into a dormant state; and receiving an acknowledgment (ACK) of the indication.

Dormancy indication in sidelink communication systems

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) entering a dormant state with respect to a secondary cell group (SCG) of a node network (SN) having a primary serving cell (PSCell). In one aspect, the UE may maintain a parameter set for at least the PSCell while the UE is in the dormant state with respect to the SCG. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The parameter change message may be transmitted as one or both of a downlink control information (DCI) or media access control (MAC) control element (CE). The UE may transmit physical layer measurements to the SN based on the parameter set.

User equipment (UE) physical layer measurement reporting in secondary cell group (SCG) dormancy

In an aspect, a UE receives, while a secondary cell group (SCG) is associated with a dormant state, at least one downlink transmit beam associated with at least one cell of the SCG. The UE determines, while the SCG is associated with the dormant state, an uplink transmit beam for a primary secondary cell (PSCell) of the SCG based on one or more of a spatial relation indication (SRI), whether there is beam correspondence between the at least one downlink transmit beam and the uplink transmit beam, a default uplink transmit beam, or a combination thereof. The UE transmits a signal related to a measurement between the UE and the one or more SCells of the SCG on the determined uplink transmit beam.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining a time to stop monitoring a wireless channel for paging information. In some examples, a user equipment (UE) may identify a plurality of paging occasions associated with a wireless channel (e.g., of an unlicensed radio frequency spectrum band) and monitor the wireless channel for paging information from a base station during a first paging occasion of the plurality of paging occasions. The UE may determine a channel occupancy status of the base station with respect to the wireless channel and may determine a time to stop monitoring the wireless channel for paging information. The UE may ignore a remainder of the plurality of paging occasions based on the determined time to stop monitoring the wireless channel.

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.

Techniques for communicating mobility information

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a first radio access network (RAN) node associated with a first subscription, a request to suspend downlink transmissions related to the first subscription based at least in part on a paging request received from a second RAN node associated with a second subscription. The UE may receive, from the first RAN node, a release message indicating that one or more core network nodes associated with the first subscription have suspended the downlink transmissions related to the first subscription. Accordingly, the UE may enter an inactive mode on a first wireless network associated with the first subscription and enter a connected mode on a second wireless network associated with the second subscription based at least in part on the release message. Numerous other aspects are provided.
