The method can additionally include transmitting the buffered data packets from the user equipment toward the target node based on the remapping.

A method for centralized device tracking includes: obtaining, at a first UE from multiple sources, first multi-source position information corresponding to a second UE; determining, based on the first multi-source position information, second multi-source position information corresponding to the second UE; identifying a third UE, separate from the first UE, to which the second multi-source position information is relevant; and sending migration information to the third UE, the migration information comprising an identifier of the second UE and comprising the first multi-source position information, or the second multi-source position information, or a combination thereof.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a measurement of a wireless signal from a first base station of a network, the measurement comprising one or more of: a Doppler shift of the wireless signal or an angular variation of the wireless signal; determine that a high speed train or tunneling (HSTT) event has occurred based at least in part on the measurement; provide, to the first base station, an indication that the HSTT event has occurred; and receive, from the first base station, configuration information to: configure the UE for a handover to a second base station of the network, configure the UE for beam switching, or cause the UE to change a connection state. Numerous other aspects are provided.

A cell handover method is disclosed. A terminal obtains a signal attenuation observation instruction, detects, in response to the signal attenuation observation instruction, signal strength and a signal attenuation parameter of a first cell, and sends the signal strength and the signal attenuation parameter to a network side device. Then, the network side device determines, based on the signal strength and the signal attenuation parameter, whether a cell handover is to be performed by the terminal. After performing a cell handover for the terminal is determined, the terminal is triggered to perform the cell handover from the first cell to a second cell. The first cell is a serving cell of the terminal, and the second cell is a neighboring cell of the first cell.

A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighbouring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

An apparatus and a method of wireless communication are provided. The method by a first next generation radio access network (NG-RAN) includes performing, by the first NG-RAN, a non-public network (NPN) cell identification on an access stratum (AS) level for downlink (DL), wherein performing, by the first NG-RAN, the NPN cell identification includes at least one of the followings: wherein a synchronization sequence for NPN can be transmitted in one or more synchronization signal blocks (SSBs) on an initial bandwidth part (BWP) by an NPN cell, wherein in a broadcasting system information on a DL BWP, an NPN identifier (ID) is present in an NPN access related information information element (IE), wherein the DL BWP for NPN is used to transmit an SSB and related system information, or wherein an access class permission is transmitted in system information on the DL BWP for NPN access allowance.

Methods, apparatuses, systems, etc., directed to performing a change of relay are disclosed herein. In an embodiment, a WTRU may transmit a link modification request message to a target WTRU via a first relay WTRU for requesting a change of relay. The WTRU may receive a link modification accept message from the target WTRU via the first relay WTRU, indicating a (e.g., proposed) second relay WTRU (e.g., identifier). The WTRU may transmit a direct communication request message including the second relay WTRU identifier for indicating to the target WTRU acceptance of the proposed second relay WTRU. The WTRU may a receiving a direct communication accept message from the target WTRU via the second relay WTRU, indicating the traffic may be relayed via the second relay WTRU.

A device may include a processor configured to determine that a user equipment (UE) device, attached to a base station, is within a coverage area of a small cell operating on a first channel, and that the UE device is not a member of the small cell and is experiencing interference on the first channel. The processor may be further configured to send an instruction to the UE device to provide a measurement report for base stations operating on another band or channel different from the first channel; receive a measurement report from the UE device identifying one or more neighboring base stations operating on the other band or channel; and perform a handover of the UE device to a neighboring base station, wherein the UE device is to communicate with the neighboring base station using the other band or channel.
