    Abstract: A user equipment apparatus (UE) includes processor(s) and memory storing instructions. The instructions, when executed by the processor(s), cause the UE to: establish a connection with a first network node via a serving cell, where the first network node supports the serving cell and supports at least one of distributed unit functionality or a layer 2 protocol of a radio access network (RAN); receive, from a second network node supporting at least one of central unit control plane functionality or a layer 3 protocol of the RAN, a radio resource control (RRC) message including configuration information relating to timing advance, where the configuration information prepares the UE for at least one candidate target cell with which the UE may connect, where the RRC message is received prior to the UE connecting with any of the at least one candidate target cell; and implement a configuration based on the configuration information.

    Abstract: In some embodiments, there is provided a method that includes receiving, by a source distributed unit, a configuration for a target distributed unit, wherein the configuration comprises at least one bandwidth part configuration for at least one transmit and receive point at the targeted distributed unit and a channel state information resource configuration of multiple transmit and receive points; in response to receiving a layer 1 measurement report for the target distributed unit, deciding, by the source distributed unit, to switch to the target distributed unit with a multiple transmit and receive points operation; and sending, by the source distributed unit, a cell switch command to a user equipment to change to the target distributed using a multiple transmit and receive points operation, the cell switch command including a bandwidth part identifier and multiple transmit and receive points beam indications. Related systems, methods, and articles of manufacture are also disclosed.

    Abstract: A user equipment apparatus (UE) includes processor(s) and memory storing instructions. The instructions, when executed by the processor(s), cause the UE at least to, establish a connection with a control network node via a serving cell, where the serving cell is supported by a source network node; receive, from the control network node and/or the source network node, timing advance (TA) cell configurations for a set of timing advance (TA) cells, where the TA cell configurations include a TA-associated random access (RA) configuration, where the set of TA cells includes first TA cells that include candidate target cells with which the UE may connect and/or other TA cells which are requested by at candidate target cells and which the UE may connect with in case the UE connects with the one of the candidate target cells; and acquire TA for the TA cell based on the TA-associated RA configuration.
