Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for a coordinated receive (or transmit) pattern during a DAPS handover. In an example implementation, the method may include a UE sending a measurement report to a first network node, the measurement report including at least a request for a time division multiplexing pattern. The method may further include receiving a radio resource control configuration from the first network node, the radio resource control configuration including at least the time division multiplexing pattern.

Abstract: Systems, methods, apparatuses, and computer program products for conditional handover (CHO) execution with network slice service continuity prioritization are provided. A radio resource control (RRC) reconfiguration message sent by a source radio access network (RAN) node to the user equipment (UE) may include, for each CHO configuration, an associated network slice-related priority index. The UE may take this index into account when selecting a suitable cell during CHO recovery. Additionally, or alternatively, the RRC reconfiguration message sent by a source RAN node may include, for each CHO configuration, an associated network slice support information of the candidate target cell. The message may also include network slice remapping information for any network slice associated with one of the candidate target cells. Using the above network slice-related information received from the network, the UE can prioritize the cell to select during CHO recovery in case more than one suitable cell is available.

Abstract: For example, a communication link between a first relay node and a second relay node, which are in synchronous movement, is established. Beam management assistance information from the first relay node is received at the second relay node upon an occurrence of beam failure at the first relay node (S801). At the second relay node it is decided about a timing at which the received beam management assistance information is to be transmitted to a serving network node (S802), and the received beam management assistance information is transmitted from the second relay node to the serving network node at the decided timing (S803).

Abstract: According to an example embodiment, a method may include receiving, by a user equipment from a serving base station associated with a source cell, a reconfiguration message that includes a target cell configuration for a target cell, a configuration of a conditional handover execution condition, and information that indicates that the user equipment should immediately decode and apply the target cell configuration upon receiving the reconfiguration message; and immediately decoding and applying, by the user equipment, the target cell configuration upon receiving the reconfiguration message, without waiting for the conditional handover execution condition to be fulfilled.

Abstract: There is provided a user equipment apparatus that includes at least one processor and memory storing instructions. The instructions, when executed by the at least one processor, cause the user equipment apparatus at least to: establish a connection with a serving cell controlled by a serving network node; perform configuration for L1/L2 triggered mobility (LTM) to a target cell, the target cell controlled by one of: the serving network node or a target network node; prior to receiving a command to switch to the target cell: transmit, towards the target cell, a random access preamble for acquiring timing advance for the target cell; and receive, from the serving network node, an instruction to acquire timing advance for the target cell.
