The invention provides a method executed by user equipment UE. The method comprises the following steps: receiving a first radio resource control (RRC) message comprising a switching command from a base station; keeping the switching configuration in the first RRC message; and managing the switching configuration. The invention also provides the user equipment and the corresponding base station. The UE still keeps communication with a source base station before receiving the RRC message comprising the switching command and before carrying out switching, thereby reducing data transmission interruption time.

A mobile communications network configured to establish communications bearers communicating data packets to / from mobile communications terminals via a radio network and core network, each communications bearer established using context information associated with one or more connections from mobile communications terminals to destination addresses, or to the mobile communications terminals from source addresses. A mobile communication terminals can, in an idle state, communicate a short message data packet to a base station of the radio network as a signalling message, using predetermined parameters configuring a transmitter of the mobile communications terminal, corresponding with parameters with which a receiver in the base station can receive the short message data packet, which includes an indication of context information used by the mobile communications network for communicating the short message data packet to a mobility manager of the mobile communications network. The short message data packet can be communicated context-less or quasi-context-less.

The present disclosure provides a method for transmitting and receiving data based on a grid of a common resource block (RB) in a wireless communication system. More specifically, the method performed by a user equipment includes receiving a synchronization block from a base station; receiving, from the base station, first offset information representing an offset between a lowest subcarrier of a lowest resource block of the SSB and a first reference point based on a specific subcarrier spacing; receiving, from the base station, control information including information on the specific subcarrier spacing and information on a difference between a subcarrier spacing based reference point, to which the SSB is received, and the first reference point; and configuring a grid of a common resource block based on the first offset information and the control information.

A method for transmitting a synchronization signal in vehicle-to-something (V2X) communication is presented. A terminal according to the present invention can determine whether to transmit a synchronization signal on the basis of the power capacity of the terminal. The terminal can reduce power consumption by transmitting the synchronization signal only within a window according to the power capacity.

A packet-switching connection is set up from a mobile station through a first transceiver unit, whereby the mobile station is assigned to a first cell and a first residence zone. As the mobile station moves to a second cell and a second residence zone, the connection is assigned a residence zone change identification. A transfer procedure for the packet-oriented connection from the first cell to the second cell is carried out. After the transfer procedure a data exchange by the packet-switched connection is reestablished. After reestablishing the data exchange a procedure for residence zone exchange is carried out.

The disclosure provides a method and a device in a User Equipment (UE) and a base station supporting random access. The UE first transmits a first radio signal, and then receives a second radio signal. A first bit block is used for generating the first radio signal, the first bit block includes a positive integer number of bits, the first bit block carries a first identifier and a first data block, the first bit block lacks a field used for indicating RRC connection request cause information, a field used for indicating RRC connection reestablishment request cause information or a field used for indicating RRC connection resume request cause information compared with a Msg3, the first data block includes a positive integer number of higher-layer bits, the second radio signal carries a second identifier. The first identifier is equal to the second identifier.
