A method of determining which of at least two connected mobile devices is to function as a host device, wherein the mobile devices first determine which of them is to act as an initial host device and which is to act as an initial peripheral device. The initial host device then receives instructions from a user as to which of the mobile devices is to be the host device. If the instructions indicate that the initial host device is to be the host device, the initial host device controls, as host device, the initial peripheral device as a peripheral device, and if the instructions indicate that the initial peripheral device is to be the host device, the initial host device passes control to the initial peripheral device to enable the initial peripheral device to control, as host device, the initial host device as a peripheral device.

A mobile terminal (20), and in particular, a mobile terminal (20), a combined terminal device (30) and a method for splicing control of mobile terminals (20). For a splicable mobile terminal (20), according to a state determination instruction, the mobile terminal (20) is caused to selectively enter a master operating state or a slave operating state; when the mobile terminal (20) operates as a master, a display partitioning unit (a2) partitions the display content of the master according to the display screen resource of individual mobile terminals (20) in a combined terminal device (30), to obtain a plurality of pieces of partitioned display data corresponding to a plurality of the mobile terminals (20) in the combined terminal device (30), and sends corresponding partitioned display data to slaves; and in a case in which the mobile terminal (20) acts as a slave, upon reception of the partitioned display data from the master, a display switching unit (a3) displays the received partitioned display data. The content displayed by the master can be displayed by the slaves, and when there are a large number of slaves, the content can be displayed to a user on a relatively large screen composed of a plurality of slaves, satisfying people's demand for a large display area.

The present disclosure relates to a 5G or a pre-5G communication system for supporting a higher data rate following 4G communication systems such as LTE. In accordance with an embodiment of the present disclosure, a method of a base station includes: checking an operation mode depending on whether beam sweeping is supported, transmitting a signal related to the operation mode to a terminal, and performing communication with the terminal according to the operation mode.

A terminal receiving a push message is provided. The terminal sets service control condition which specifies application identifier (app ID) corresponding to service that the terminal is allowed to receive, wherein the service control condition is contained in push message control policy. And the terminal then receives a push message, matching the push message control policy, sent by a server.

A communications device transmits and receives data via a wireless access interface in a mobile communications network. First resource allocation messages are received by communications devices to allocate one or more of plural communications resource elements of a host frequency range of a host carrier. Second resource allocation messages are received by reduced capability devices to allocate one or more of a first section of the communications resources within the first frequency range for preferable allocation to the reduced capability devices of a first virtual carrier, the first resource allocation messages identifying one or more of the communications resource of the host carrier allocated to the communications devices with reference to a first reference frequency and the second resource allocation messages identifying one or more communications resources of the first virtual carrier allocated to the reduced capability devices with reference to a second reference frequency within the first virtual carrier.

A user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.

An overheating protection method for user equipment includes: sending a first signaling to a base station, the first signaling carrying indication information indicating that the user equipment has a capability of reporting a temporary capability of the user equipment; receiving a second signaling returned by the base station in response to the first signaling; and when the user equipment is overheated due to a wireless link configuration being too high, sending a third signaling for adjusting the wireless link configuration to the base station, the third signaling carrying assistance information indicating the base station to solve an overheating problem of the user equipment.

Systems, methods, apparatuses, and computer program products for an uplink timing synchronization recovery process for RACH-less handover are provided. One method includes detecting, by a network node, that at least one uplink transmission has not been successfully received from a user equipment. The method may also include transmitting a physical downlink control channel (PDCCH) order to the user equipment for re-initiating random access procedure (RACH) in order to become uplink synchronized.

A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first reduced bandwidth carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second reduced bandwidth carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.
