A method for determining a serving cell is performed by a user equipment (UE), wherein a current serving cell of the UE is a non-terrestrial network (NTN) cell. The method includes: when an acquisition situation of location information of the UE does not meet a preset condition, determining a new serving cell.

In a first aspect, a communication control method is used in a mobile communication system including a user equipment and a base station, and being capable of performing wireless communication between the user equipment and the base station. The communication control method includes receiving, by a first layer of a user equipment in a Radio Resource Control (RRC) idle state or an RRC inactive state, system information from the base station. The communication control method includes notifying, by the first layer of the user equipment, a second layer higher than the first layer of at least one of first information indicating whether slice-specific cell reselection is available and second information indicating whether a slice-specific random access channel is available, based on the system information.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In an embodiment, a method of performing Minimising Drive Test (MDT) of a user equipment (UE) in a wireless communication system is provided. The method comprises: receiving, from a base station, a configuration including inter radio access technology (IRAT) frequencies; performing measurement on available IRAT frequencies based on the configuration; and logging the measurement results.

Methods, systems, and devices for wireless communication are described. A user equipment. UE (115-a), may perform a cell measurement for at least some of a set of cells while operating in a connected mode. The UE may determine a subset of cells of the set of cells based on one or more of the cell measurement, cell-specific information (210), or UE-preferred cell information (215). The cell-specific information may include one or more respective cell parameters associated with at least some if not each cell of the subset of cells. The UE-preferred cell information may include one or more respective preferred cell parameters. The UE may transmit a cell measurement report (205) including an indication of one or more cells of the subset of cells based on the one or more cells of the subset of cells satisfying one or more cell measurement report criteria.

Provided is a process including: advertising a plurality of values corresponding to computing components to peer nodes of a peer-to-peer network; storing the plurality of values in a tamper-evident, distributed ledger; determining a target data center in the distributed computing environment, wherein the target data center performs computations based on data sent from a mobile computing device, and wherein the target data center executes a peer node of the peer-to-peer network; determining a network path that is linked to the target data center based on a distance to the target data center; and transferring a packet from the target data center, wherein the packet traverses the network path and comprises one or more computation results from the target data center.

A user equipment (2) has an ability to operate according to one or more spectrum emission requirement capability values (14) in a wireless communications network having at least a first serving cell (4). A message (6) is received at the user equipment (2) from the first serving cell (4) comprising a first indicator representing a first band designation (8), a second indicator representing a spectrum emission requirement value (10), and at least one additional indicator representing at least one additional spectrum emission requirement value (12), both the first and additional indicators relating to the first band designation. The user equipment (2) performs a comparison of the first and additional spectrum emission requirement values (10, 12) with the one or more spectrum emission requirement capability values (14) and determines a behavior of the user equipment (2) in relation to the first serving cell (4) in dependence on the comparison.

Disclosed is a method of supporting/using Device-to-Device (D2D) communication supporting user equipment (UE) mobility in a wireless mobile communication system. A method and an apparatus for performing D2D communication includes receiving system information of at least one of a serving cell and an adjacent cell of the UE. The method and apparatus for performing D2D communication also includes determining whether cell redirection is required to perform the direct communication based on the system information. The method and apparatus for performing D2D communication further includes performing the cell redirection on the adjacent cell when the cell redirection is required according to a result of the determination.

The present invention is to enable setting of an appropriate subordinate cell or subordinate base station according to quality of a wireless communication service applied to a terminal or a type of a terminal. The terminal (3) is connected to a wireless communication network via a base station (1A), and when the base station (1A) sets another base station (1B or 1C) as the subordinate cell or the subordinate base station, the base station (1A) selects the subordinate cell or the subordinate base station from among either (a) candidates according to QoS (Quality of Service) applied to the terminal or (b) candidates according to the type of the terminal.

A UE capability reporting method is provided to resolve a problem that when UE is handed over from a source access network device to a target access network device, UE capability information obtained by the target access network device is incomplete. A solution is as follows: UE obtains first information, where the first information is used to indicate a UE capability supported by a target access network device; and the UE reports second information based on the UE capability supported by the target access network device and a UE capability of the UE, where the second information includes capability information, other than UE capability information stored in a source access network device, in target capability information, and the target capability information is UE capability information of a lower UE capability in the UE capability of the UE and the UE capability supported by the target access network device.

A communication method, including: A terminal device receives a master information block MIB, where the MIB includes first indication information and second indication information, the first indication information indicates whether a cell is barred, and the second indication information indicates whether an intra-frequency reselection operation is allowed. When the first indication information indicates that the cell is barred, the terminal device determines, based on the second indication information, whether to perform the intra-frequency reselection operation. The terminal device is reduced capability user equipment RedCap UE. Based on this technical solution, the RedCap UE can use different IFRIs when the cell is barred, to improve efficiency of the terminal device to determine to perform a cell reselection operation.
