A method of processing state information relating to user equipment in a communications system comprising a radio access network, the method comprising: maintaining current state information relating to the user equipment; and on the basis of a change of connection of the user equipment from a first cell to a second cell: transmitting a current value associated with a given state information part to the target radio access node in response to detecting at least one of one or more predetermined triggers that indicate that the target radio access node may not have received the current value from the source radio access node; or relying on the target radio access node having received the current value from the source radio access node if said at least one of said one or more predetermined triggers is not detected.

Embodiments of the present application provide a resource processing method and apparatus, a device, and a storage medium, where the method includes: when a terminal device accesses a network, generating first information including a handover report, and sending the first information, correspondingly, a source network device can receive at least one piece of first information sent by at least one terminal, and each piece of first information includes: a handover report of a corresponding terminal device. Therefore, the source network device can adjust, according to the handover report of the at least one terminal device, a reserved resource allocated by the network device, which further adjusts the coverage and the size of the resource pool reserved for the terminal device in conditional handover, which improves the matching degree between the reserved resources allocated tar the terminal device and the terminal device, solves the problem of resource waste or resource shortage.

Embodiments provide a user equipment handover method, and a device. In embodiments of the present invention, when a handover is to be performed, user equipment may send first information that is used to request a handover, and then a destination network device may allocate a first uplink resource to the user equipment.

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.

Apparatuses, methods, and systems are disclosed for selecting a base unit in response to a handover condition being triggered. One method (1000) includes selecting (1002) a base unit of multiple base units for handover in response to at least one base unit of the multiple base units triggering a handover condition. The method (1000) includes transmitting (1004) a random access preamble to the base unit. The method (1000) includes performing (1006) a reestablishment procedure to establish communication with one base unit of the multiple base units in response to determining an inability to access each base unit of the multiple base units that meets the handover condition.

A network migration method, a network migration apparatus, a communication device, and a communication system. The method includes: implementing a migration procedure of a first IAB node according to a received first migration command in a case that a target migration command has been transmitted to a target network node, where the target network node is a downstream child IAB node of the first IAB node or UE served by the first IAB node in an IAB network, the target migration command includes migration commands corresponding to all downstream network nodes of the first IAB node in the IAB network, and the first migration command is a migration command corresponding to the first IAB node.

Aspects of the present disclosure implement techniques of a new 3D waveform coding scheme that leverages the spatial properties of 5G NR systems. Specifically, in 5G systems, each UE location may be characterized by three parameters: propagation delay (t.sub.p), angle of elevation (θ), and angle of azimuth (φ). Global coding matrix may be generated by linear combination of these three attributes and a unique lattice code may be generated for each UE at different locations from the base station. Thus, considering the coding gain increases with increasing the distance between the codes, aspects of the present disclosure take advantage of geometrical properties of lattice. Particularly, within the 3D waveform coding, if lattice distance between co-beamed UEs is determined to be greater than threshold radius, a conjugate lattice code for the UEs may be applied in accordance with aspects of the present disclosure.

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a first node in a wireless communication system is provided. The method includes transmitting a first message to a second node, the first message indicating a migration request to migrate a third node, which is connected to the first node, to the second node, receiving a second message in response to the first message from the second node, the second message indicating a response to the migration request, and determining whether the third node can migrate to the second node based on the received second message.

A method of processing state information relating to user equipment in a communications system comprising a radio access network, the method comprising: maintaining current state information relating to the user equipment; and on the basis of a change of connection of the user equipment from a first cell to a second cell: transmitting a current value associated with a given state information part to the target radio access node in response to detecting at least one of one or more predetermined triggers that indicate that the target radio access node may not have received the current value from the source radio access node; or relying on the target radio access node having received the current value from the source radio access node if said at least one of said one or more predetermined triggers is not detected.

An apparatus for use by a UE configured to conduct a communication in a communication network. The apparatus is configured to receive and process signals from the communication network via signal receiving portions, wherein one of the signal receiving portions is a serving cell signal receiving portion used for connecting to the communication network via a serving cell, and another of the signal receiving portions is a non-serving cell signal receiving portion being not used for connecting to the communication network. A signal receiving portion specific offset value is obtained for each of the signal receiving portions. Signal quality values for signals received by the signal receiving portions from the communication network are measured, wherein the cells include the serving cell. A measurement report is sent to the communication network on the basis of the results of the signal quality measurements and the offset values for the signal receiving portions.
