Abstract: The present disclosure describes methods, system, and devices for configuring supporting a layer 1 or layer 2 signaling (L1/L2) based inter-cell mobility. One method includes supporting, by a first network node, a mobility triggering for a user equipment (UE) from the first network node to a second network node by: sending, by the first network node, a first message for the UE to a third network node, the first message comprising mobility information indicating a list of to-be-switched candidate cells for the UE. Another method includes supporting, by a third network node, a mobility triggering for a UE from a first network node to a second network node by: receiving, by the third network node, a first message for the UE from the first network node, the first message comprising mobility information indicating a list of to-be-switched candidate cells for the UE.

Abstract: This document generally relates to wireless communication that includes a first communication node that adds a time value to a history information of a user device in response to a dwelling time exceeding 4,095 seconds or exceeding a predetermined upper time value that the user device stays in a cell, where the time value accurately indicates the dwelling time. The first communication node may transmit the history information including the time value to a second communication node. Also, at least one communication node may add time values to at least one history information, where the time values indicate dwelling times that a user device is in cells. At least one of the time values is for a dwelling time that exceeds 4,095 seconds or a predetermined upper time value and accurately indicates the dwelling time. The at least one communication node may correlate the at least one history information.

Abstract: Methods, apparatus, and systems that enable lossless Multicast and Broadcast Service (MBS) data transmissions in handovers between network nodes that may or may not support MBS are disclosed. In one example aspect, a wireless communication method includes requesting, upon determining by a first access node to perform a handover procedure for handing over a wireless device to a second access node, a switch of an ongoing multicast and broadcast services (MBS) session of the wireless device from a shared channel to a unicast tunnel with a core network. The method also includes initiating, after the switching, the handover procedure from the first access node to the second access node.

Abstract: A system and method for communication between a wireless communication device, a wireless communication node, and a core network are disclosed herein. In one embodiment, the system and method are configured to receive, by the core network, communication configuration information associated with a wireless communication device. The core network can refrain from transmitting to a wireless communication node a downlink packet size associated with the wireless communication device, when a downlink data packet size is greater than a downlink transmission capability of the wireless communication device. The core network can transmit to the wireless communication node, the downlink packet size in a paging message, when the downlink data packet size is less than or equal to the downlink transmission capability of the wireless communication device.
