In some embodiments, there may be provided a method that includes receiving timing advance acquisition parameters associated with multiple transmit receive points at a target distributed unit, wherein the timing advance acquisition parameters comprise, for the multiple transmit receive points, synchronization signal block indices, random access preamble indices, and physical random access channel mask indices; sending downlink control information to a user equipment, the downlink control information comprising an identifier of the target distributed unit, codepoints for the synchronization signal block indices, the random access preamble indices, and the physical random access channel mask indices; receiving timing advance estimates from the target distributed unit, wherein the timing advance estimates comprise estimates of timing advances associated with multiple transmit receive points at the target distributed unit; and sending the timing advance estimates associated with the multiple transmit receive points at the target distributed unit, to the user equipment.

Multi timing advance acquisition for a candidate cell in L1/2-triggered mobility

There is provided a user equipment apparatus (UE) that 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 control network node supports at least one of control unit-control plane functionality or a layer 3 protocol of a radio access network; receive, from the control network node, an RRC message that includes: configuration information for preparing the UE for candidate target cell(s) with which the UE may connect, and further configuration information for preparing the UE to acquire timing advance (TA) for other cell(s) with which the UE may connect and/or perform cell detection/measurement, where the further configuration information is received prior to the UE connecting with any of the other cell(s); and implement a configuration based on the configuration information and the further configuration information.

Requesting timing advance acquisition for other cells

An apparatus, method and computer program product for: performing channel availability monitoring on an operating channel for transmitting uplink control information for transmitting a data packet, in response to determining that the operating channel is available for transmitting the uplink control information, determining delay information relating to the channel availability monitoring, and transmitting the uplink control information and the delay information to the radio access network.
