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.

Beam management for a secondary cell group in a dormant state

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

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Random access channel occasion configuration

Methods, computer program products, and apparatuses for network slices based on master cell group (MCG) or secondary cell group (SCG) configurations are provided. An example method may include transmitting, to a base station, a registration request comprising first single network slice selection assistance information (S-NSSAI) associated with a first network slice and second S-NSSAI associated with a second network slice. The method may include receiving, from the base station, a registration accept message associated with the first network slice and the second network slice. The first network slice may be associated with a first priority higher than a second priority associated with the second network slice. The first network slice may be served by an MCG and the second network slice may be served by an SCG. The method may include initiating a first inactivity timer for the MCG and a second inactivity timer for the SCG.

Fast slicing switching via SCG suspension or activation

Aspects described herein relate to requesting suspending of a data session of a first when a device capable of communicating over multiple subscriptions switches from an active communication state if the first network to an active communication state in a second network. The device can also request resuming the data session based on switching back to active communication state with the first network.

Techniques for managing sessions in multiple-subscription wireless communications

Wireless communications systems and methods related to beam failure detection (BFD) in a dormancy bandwidth part (BWP) are provided. A user equipment (UE) determines to operate in a dormancy mode for a cell of a wireless communication network. The UE operates in the dormancy mode for the cell of the wireless communication network, where the operating in the dormancy mode includes performing a beam failure detection (BFD) in a dormancy bandwidth part (BWP) based on a configuration. The configuration may include a control resource set (CORESET) configuration for the dormancy BWP.

Beam failure detection (BFD) in dormancy bandwidth part (BWP)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a resource status request requesting load information related to load balancing between the wireless communication device and one or more other wireless communication devices. The wireless communication device may receive a resource status response including the load information in response to the request. In other aspects, a User Equipment (UE) may receive a Radio Resource Control (RRC) configuration including a set of target cells for a conditional handover procedure and load information of the target cells. The UE may select a target cell from the set of target cells for the conditional handover procedure based at least on the load information of the target cells. Numerous other aspects are provided.

Mobility load balancing in wireless communication network

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in dual connectivity with a master node (MN) that has a capability to operate in a particular frequency band range (e.g., a range above 6 gigahertz (GHz)) and a secondary node (SN). The MN or SN may transmit an indication to an SN or MN, respectively, that includes sets of frequency bands in which the UE may measure, including frequency bands within the particular frequency band range. The SN or MN that received the indication may update a gap pattern for at least one of the frequency bands within the particular frequency band range and transmit an updated gap configuration to the MN or SN that transmitted the indication. Additionally, the MN or SN may choose fixed gap pattern configuration roles or may both dynamically identify gap patterns.

Measurement gap configuration and coordination

Aspects of the disclosure relate to wireless communications utilizing dormancy indications for secondary cells (SCells) and determining application delay times based on the dormancy indications.

Secondary cell dormancy indication and application delay

This disclosure provides systems, methods and apparatuses for early measurement associated with configuring with multiple secondary nodes (SNs). In one aspect, the configuration of multiple SNs may be improved by allowing a master node (MN) to determine a multi-SN configuration based at least in part on measurements of actual channel conditions as seen by the UE. Enabling the MN to receive the measurement information early during a process associated with establishing a connection between the UE and the MN may thereby improve efficiency and reduce latency associated with the configuration of multiple SNs.

Radio (NR) early measurement with multiple secondary nodes (multi-SNs)

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes determining, by a user equipment (UE), listen before talk (LBT) information associated with new radio-unlicensed (NR-U) operation of the UE. The method further includes transmitting, by the UE, a report including the LBT information. Other aspects and features are also claimed and described.

Radio access network (RAN)-centric data collection for new radio (NR)-unlicensed (U)

A method of wireless communication for a user equipment (UE) includes entering a dormancy period for a secondary cell group (SCG) of a base station (BS) during which no downlink (DL) data or control transmissions are received from the SCG; performing a channel state information (CSI) measurement on the SCG during the dormancy period to generate a measurement report; determining an uplink (UL) beam of a primary secondary cell (PSCELL) of the SCG; transmitting the measurement report to the BS on the UL beam of the SCG; and determining, during the dormancy period and after transmitting the measurement report, one or more downlink (DL) beams for communicating on the SCG based on one or more rules and based on the measurement report, wherein the one or more rules result in the BS determining the same one or more DL beams based on the measurement report.

Beam updates during a secondary cell group (SCG) dormancy period

Methods, systems, and devices for wireless communications are described. A UE may identify a non-dormant mode configuration for measuring cross-link interference in a non-dormant mode for a cell. The UE may receive, from a base station, an indication to switch to a dormant mode for the cell and may identify a dormant mode configuration for measuring the cross-link interference in the dormant mode. The UE may measure the cross-link interference in the dormant mode based on the identified dormant mode configuration and receiving the indication to switch to the dormant mode. The UE may transmit, to the base station, an indication of the measured cross-link interference.

Cross-link interference measurements for cell dormancy

Certain aspects of the present disclosure provide techniques for paging based on a paging early indication (PEI). Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes determining a set of paging cycles for receiving paging information from a base station (BS), receiving a first paging early indicator (PEI) from the BS in a first paging cycle of the set of paging cycles, wherein the first PEI indicates whether the paging information will be transmitted to the UE in one or more second paging cycles of the set of paging cycles occurring after the first paging cycle, and receiving the paging information in the one or more second paging cycles based on the first PEI received in the first paging cycle.
