A synchronization device that synchronizes time-series data between a master and a slave by wireless communication, the master including a packet transmission unit that transmits a plurality of packets at a predetermined interval, and the slave including a synchronization unit that synchronizes time-series data transmitted by the master and time-series data received by the slave on the basis of the interval between the plurality of packets.

Embodiments of the present disclosure relate to methods, devices, and medium for communication. According to embodiments of the present disclosure, the terminal device transmits the assistant information to the network device. The assistant information indicates preferences of the terminal device. The network device determines configuration information based on the assistant information and transmits the configuration information to the terminal device. In this way, the configuration is suitable to the terminal device.

The present application relates to the field of wireless communications, and in particular to a relay device selection method and device, and a computer storage medium, which are used for selecting a relay device for a remote device. In the embodiments of the present application, a remote device determines channel quality information of a first sidelink between the remote device and at least one candidate relay device and channel quality information of a second sidelink therebetween, and selects a relay device to be used from among the at least one candidate relay device according to the channel quality information of the first sidelink corresponding to the candidate relay device and the channel quality information of the second sidelink corresponding thereto.

A terminal includes: a receiving unit receiving single control information for scheduling a plurality of cells; and a control unit receiving a transport block from the plurality of cells, based on the control information, in which the control unit: receives different transport blocks in each of the plurality of cells; receives a same transport block in each of the plurality of cells; or receives a part of a transport block in each of the plurality of cells.

Embodiments of this application provide a cell selection method and an apparatus, and relate to the communications field. A terminal may determine a first measurement frequency and a 5G anchor cell at the first measurement frequency based on prior historical information. The terminal may shorten evaluation duration corresponding to a 5G anchor cell that meets a preferred condition at a first measurement frequency, so as to improve a probability that the terminal camps on the 5G anchor cell.

In accordance with an example embodiment of the present invention, a method comprising determining, by a user equipment in a radio resource control inactive state, whether information has been received from a wireless network, wherein the information is configured to cause the user equipment to access the network; and triggering, by the user equipment and in response to receiving the information, an access to the wireless network, is disclosed.

A method and apparatus for reporting data transmission procedure failure for network optimization in a wireless communication system is provided. A wireless device performs the data transmissions to a network in idle state and/or inactive state. A wireless device detects failures of the data transmissions. A wireless device logs information related to each of the failures and counts a number of the failures, while the logging validity timer is running. A wireless device establishes or resumes a connection with the network based on that the counted number is equal to or bigger than a threshold value.

A terminal includes a reception unit configured to receive information for allocating uplink transmission from a base station; a control unit configured to determine a CP extension value in a case where a parameter for calculating the CP extension value is not configured by the base station upon receiving the information; and a transmission unit configured to execute the uplink transmission by applying the determined CP extension value.

Disclosed are a method and device for transmitting/receiving a downlink channel from multiple transmission/reception points in a wireless communication system. A method for a terminal to receive a downlink channel in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a downlink control channel on the basis of two or more transmission configuration indicator (TCI) states associated with one or more control resource sets (CORESETs); and receiving a downlink data channel on the basis of the two or more TCI states associated with one or more CORESETs, on the basis of TCI information not being included in downlink control information (DCI) received through the downlink control channel, wherein the two or more TCI states may be mapped to the downlink data channel on the basis of a prescribed mapping scheme.
