    Abstract: There is provided an apparatus comprising means for: receiving, at a user equipment from a first access point supporting a serving cell, one or more user equipment specific allocations of a random access preamble and timing information associated with the random access preamble, the timing information indicating when the user equipment is to use the associated random access preamble; responsive to the receiving, starting a timer; and sending, to a second access point supporting a target cell, a random access request including one of the one or more random access preambles, the included random access preamble being selected based on a value of the timer and the timing information.

    Abstract: A method is provided that includes receiving a configuration of selection criteria for a timing advance (TA) of a target cell, acquired by respective acquisition schemes including a user equipment (UE)-based acquisition scheme and a random access channel (RACH)-based acquisition scheme. The method includes acquiring a UE-based TA value according to the UE-based acquisition scheme, and transmitting a random access preamble to the target cell that is configured to acquire a RACH-based TA value according to the RACH-based acquisition scheme. The method includes receiving a cell-switch command from a serving cell to trigger a cell switch to the target cell, after the UE-based TA value and the RACH-based TA value are acquired. And the method includes accessing the target cell using a TA value selected from the UE-based TA value and the RACH-based TA value, based on the configuration.

    Abstract: An apparatus comprising means for sending a response to the first target master node based on the received first request in response to receiving a first secondary node addition request for the user equipment from a first target master node, means for sending a response to the second target master node based on the received second request in response to receiving a second secondary node addition request from a second target master node for the same user equipment; and means for enabling, in response to receiving a physical uplink shared channel message from the user equipment, decoding of the physical uplink shared channel message received from the user equipment based on a first target master node key associated with the first target master node in case no information is available whether user equipment accessed first or second target master node, and, if decoding with the first key not successful, decoding based on a second target master node key associated with the second target master node.

    IPC: H04W74/0838

    Abstract: An apparatus (DU) comprising: means for receiving an identification of a serving network access node; and means for associating a sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node. An apparatus (CU) comprising: means for sending a first message comprising an identification of a serving network access node (sDU) to enable association of a sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node (sDU); and means for receiving, in reply, a second message specifying the association of the sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node (sDU).
