Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for a set of random access channel (RACH) procedure types for a bandwidth part of the UE, each RACH procedure type in the set of RACH procedure types being different from at least some if not all the other RACH procedure types in the set of RACH procedure types. The UE may select a RACH procedure type from the set of RACH procedure types for the RACH procedure based at least in part on the indication of the configuration for the set of RACH procedure types and on a trigger to perform a RACH procedure for a network slice. The UE may perform the RACH procedure for the network slice according to the RACH procedure type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a radio resource control (RRC) idle mode or an RRC inactive mode, a paging message that includes an indication identifying an intended slice for a protocol data unit (PDU) session associated with downlink traffic for the UE. The UE may transmit, to a base station, a request to initiate a random access channel (RACH) procedure based at least in part on the intended slice. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support carrier aggregation for a sidelink control connection, such as a PC5 or radio resource control (RRC) connection with another UE. The sidelink control connection may support at least two sidelink control carriers, such as an anchor sidelink carrier, a secondary or selected sidelink carrier, a secondary anchor sidelink carrier that may be configured for fallback or duplication, among others. The sidelink control connection may be monitored for radio link failure and a secondary sidelink carrier may be used. Other sidelink carriers may be configured for the sidelink control connection as channel conditions change.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may relay wireless communications between a first base station and a second UE via at least a sidelink communication link with the second UE. The first UE may transmit, to the first base station, a measurement report for one or more candidate base stations, the measurement report indicating that the one or more candidate base stations support sidelink relay operation. The first UE may receive instructions to perform a handover procedure from the first base station to a second base station of the one or more candidate base stations based on the measurement report, where the second base station supports sidelink relay operation. The first UE may then perform the handover procedure including establishing a wireless connection with the second base station based on the instructions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a trigger for the UE to perform a RACH procedure to access a network slice (e.g., service). The UE may receive, from a base station, a random access configuration for performance, by the UE, of random access with a physical network. The UE may identify a network slice to be accessed by the UE, where the network slice may be supported by a logical network associated with the physical network. The UE may select a slice-based random access procedure (e.g., two-step slice-based random access procedure, four-step slice-based random access procedure) based on the random access configuration and the network slice to be accessed by the UE. The UE may perform, with the base station, the slice-based RACH procedure in accordance with the selected slice-based RACH procedure type.

Abstract: Aspects relate to random access procedures. Different random access channel (RACH) configurations may be defined for different service groups. For example, one or more service groups (e.g., network slice groups) may be defined where each service group includes one or more services (network slices). One RACH configuration may be defined for one service group, another RACH configuration may be defined for another service group, and so on. Each service group may be configured with a different set of RACH parameters. Within each service group, one or more services may be configured with dedicated (e.g., non-cell-specific) RACH resources, and other services may be configured with cell-specific RACH resources. Each service group may be configured with different RACH resources. Within each service group, one or more services may be configured with a set of dedicated (e.g., non-cell-specific) RACH parameters, and other services may be configured with a set of cell-specific RACH resources.

Abstract: Certain aspects of the present disclosure provide techniques for paging in sidelink L2 relay scenarios. An example method generally includes receiving, from one of a network entity or a relay UE to which the remote UE is connected, an indication to transition from a connected state to an idle or inactive state; and transitioning into an idle or inactive state in response to receiving the indication.

Abstract: Certain aspects of the present disclosure provide techniques for RRC connection reestablishment by a remote UE. In some cases, a remote UE may be configured to detect, on at least one of a first link between a first relay UE and a first network entity or a second link between the remote UE and the first relay UE, a radio link failure (RLF) resulting in a loss of radio resource control (RRC) connection and attempt to reestablish RRC connection by performing at least one of relay selection or cell selection.

Abstract: Aspects of the present disclosure provide techniques for configuring and triggering conditional handover for UE mobility between a direct connection to the base station (Uu connection) and/or a relay connection (PC5 connection). Specifically, the conditional handover configuration may include preparing multiple candidate relay UEs for handover (e.g., from Uu connection to PC5 connection) and conditional handover execution criteria for relay selection (or reselection) for the UE. Similarly, features of the present disclosure provide techniques for conditional handover transition from a PC5 connection back to Uu connection when conditional handover execution criteria are met (e.g., sidelink signal strength between the two UEs falls below a channel condition threshold). Additionally, the techniques provided herein support for conditional handover of the relay UEs from a first base station to a second station while the relay UE is further supporting one or more remote UEs.
