Example aspects include a method, apparatus, and computer-readable medium for network-triggered reestablishment by a network node of a wireless communication network, comprising transmitting, to a user equipment (UE) in a connected state with a first central unit (CU), an indication to perform a radio resource control (RRC) reestablishment procedure with a second CU. The indication comprises a reestablishment cell identifier. The aspects further include performing the RRC reestablishment procedure with the UE to transfer the UE from the first CU to the second CU using the reestablishment cell identifier.

A base station central unit transmits to a first base station distributed unit (BS-DU), a first power value for uplink transmission of a wireless device to the first BS-DU. A second request to add the second BS-DU for the wireless device is transmitted to a second BS-DU. The second request comprises a second power value for uplink transmission of the wireless device to the second BS-DU. A third power value for uplink transmission of the wireless device to the first BS-DU is transmitted to the first BS-DU. The third power value is based on the second power value.

The present invention provides a method of providing configuration of cell search information for a network device of a non-terrestrial network (NTN). The network device has a serving cell on which a mobile device is allowed to camp. The method includes a step of transmitting at least one location information of reference points for the configuration of cell search information for at least one mobile device, to configure the mobile device to determine whether to perform cell search for cell reselection according to the configuration of cell search information.

A method performed by a first base station, is described. The first base station determines a change in one or more measurements to be performed by a UE. The measurements are associated with a first set of frequencies. The first base station also transmits a first message to a second base station comprising information regarding which frequencies in the first set are to be changed. The first base station and the second base station serve the UE. A method performed by the second base station is also described whereby the second base station receives the first message. In a method performed by the UE, the UE receives, from the first base station, a configuration message configured to specify the measurements to perform and a measurement gap configuration. The UE then takes the measurements based on the configuration message.

A message receiving method and a message receiving apparatus, a message sending method and a message sending apparatus, a device and a storage medium are provided. The message receiving method includes: sending by the first network element a request message to a second network element, where the request message is used to indicate the second network element to send a request acknowledgement message; receiving the request acknowledgement message sent by the second network element, where the request acknowledgement message carries grid information of a target cell; and updating grid information of the first network element according to the grid information of the target cell carried in the request acknowledgement message.

Certain aspects of the present disclosure relate to methods and apparatus for grant processing in uplink centric subframes. An example method generally includes transmitting a first subframe comprising a first grant that includes information for one or more transmissions on that allocated resources in the first subframe to a user equipment (UE) and transmitting the first subframe, with a second grant that allocates resources in at least a second subframe to occur after the first subframe. Other aspects, embodiments, and features are also claimed and described.

Provided is a control apparatus including a connection control unit configured to control communication connection with a mobile station, and a handover control unit configured to carry out, in a case where the mobile station is a mobile station of a predetermined type, control over handover of the mobile station to a cell in a frequency band that is predetermined as a frequency band corresponding to the mobile station of the predetermined type.

A capability interaction method and a related device capable of enabling a network device to learn about capability information of an adjacent network device. The method comprises: obtaining capability information of at least one adjacent network device and/or at least one adjacent cell; and determining, on the basis of the capability information of the adjacent network device and/or at least one adjacent cell, a configuration of a radio resource for at least one terminal device.

The present disclosure relates to a communication technique for fusing, with an IoT technology, a 5G communication system for supporting a higher data transfer rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retailing, security and safety-related services, etc. on the basis of 5G communication technologies and IoT-related technologies. Disclosed in the disclosure is a method for measurement report/event operation and network signaling in an UE autonomous handover.

A cell handover method and a device are provided. The method is executed by a terminal device and includes: handing over to a target cell or a target TRP in a case that at least one of the following is satisfied: a first CORESET is associated with the target cell or the target TRP; related information of a first TRP points to the target cell or the target TRP; a first RS points to the target cell or the target TRP; a first TCI points to the target cell or the target TRP; first spatial relation information points to the target cell or the target TRP; or a first RACH resource points to the target cell or the target TRP.
