Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information associated with monitoring link quality on a non-serving cell of the UE, wherein the configuration information includes at least one of: information indicating a reference signal resource associated with the non-serving cell, or information indicating an uplink resource associated with the non-serving cell; monitor a reference signal of the non-serving cell based at least in part on the configuration information; and transmit, to a serving cell using the uplink resource, a channel quality indicator associated with the non-serving cell based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: A configuration to enable a UE to switch an active BWP for one or more component carriers in a set of multiple component carriers. The apparatus receives a first configuration for carrier aggregation involving multiple component carriers. The apparatus receives an indication for a BWP switch for one component carrier of the multiple component carriers. The apparatus applies the BWP switch to the one component carrier and a set of additional component carriers.

Abstract: Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility. Within a serving cell having a plurality of remote radio heads, each remote radio head transmits a referenced signal that includes a PCI index unique to the remote radio head. A user equipment is configured with a beam management function that uses one of the reference signals as a source reference signal for the beam management. The source reference signal is uniquely tied to the corresponding remote radio head through its PCI index.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling L1 (physical layer) and L2 (medium access control (MAC) layer) inter-cell mobility. More specifically, rules and operations performed during L1/L2 based cell handover operations. In certain aspects, a user equipment (UE) is configured to receive, from a network entity of a source cell via at least one of L1 or L2 signaling, a handover command for the UE to handover from the source cell to a target cell. The UE may determine at least one transient period during which the UE is served by both the source cell and the target cell, and perform the handover while communicating with the source cell and target cell during the transient period.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits at least two first random access messages (Msg 1) to multiple transmission reception points (TRPs) of at least one cell using different resources for the multiple TRPs. The UE monitors for at least two second random access messages (Msg 2) from the multiple TRPs of the at least one cell using different resources for the multiple TRPs.

Abstract: Aspects relate to Layer 1/Layer 2-centric inter-cell mobility communication systems where measurement information from at least one user equipment (UE) is sent to a base station. Based on this information, the base station may select at least one of a remote radio head (RRH), a serving cell, or a cell assigned with a physical cell ID that serves a particular UE using one of Layer 1 or Layer 2 control signaling based on the received measurement information and a system serving cell configuration or mode of operation. Additionally, an indication may be provided of whether cell configurations are the same for target and source cells in an inter-cell handover and a UE may utilize the same source cell configuration during a handover when connecting with the target cell when the configurations match or at least partially match.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a cell that has been selected for serving a user equipment (UE). The base station may provide a joint indication to the UE. The joint indication may include information associated with the cell that has been selected for serving the UE, information associated with one or more beams to be used for the cell, or information associated with one or more path loss reference signals to be used for the one or more beams. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility systems and determining timing advance groups (TAGs) within such systems. User equipment (UE) are configured to report one or more grouping of cells to a radio access network (RAN), where the cells for each group have similar propagation delays and/or signal quality. Each reported group can be assigned to a TAG identifier (ID) by the RAN. The RAN may utilize the TAG IDs to time division multiplex uplink and/or downlink transmissions based on the TAG IDs.

Abstract: Aspects of the disclosure relate to configuring, restricting, and/or setting bandwidth part (BWP) or frequency locations for switching from source to target cells in a Layer 1 (L1)/Layer 2 (L2)-Centric Inter-Cell Mobility communication systems. Switching may be allowed for either same, overlapping, or non-overlapping BWPs within an intra-frequency bandwidth shared by the source and target cells.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling L1 (physical layer) and L2 (medium access control (MAC) layer) inter-cell mobility. An example method generally includes transmitting, to a network entity, a report indicating a capability of the UE to support one or more inter-cell mobility procedures based on at least one of physical (PHY) layer or medium access control (MAC) layer signaling, receiving PHY layer or MAC layer signaling related to an inter-cell mobility procedure, and initiating at least one of the inter-cell mobility procedures based on the received PHY layer or MAC layer signaling.
