A master terminal transmits sound waves that are a synchronization signal from a speaker to a slave terminal at random time intervals. Upon acquiring the sound waves that are the synchronization signal by microphone, the slave terminal promptly transmits a response signal through wireless communication to the master terminal. The master terminal receives the response signal and a terminal ID transmitted from the slave terminal. The master terminal receives the response signal multiple times and determines whether time intervals when synchronization signals were transmitted and time intervals when response signals were received match. When the synchronization signal time intervals and the response signal time intervals match, the master terminal recognizes the slave terminal that transmitted response signals at time intervals matching the synchronization signal time intervals as a wireless communication connection target. Slave terminals that transmitted response signals at time intervals not matching the synchronization signal time intervals are excluded from wireless communication connection targets.

The present disclosure relates to a wireless backhaul implementation method, device and base station. The method comprises the steps: receiving an access request message, where the access request message carries the identity identification information; determining, according to the identity identification information, that the device requesting access is the first only capable of wireless backhaulcapability And determining, by the base station, whether to allow the first base station to access based on an available wired bandwidth of the wired backhaul link with the core network; returning aresponse message to the first base station, where the response message is used to indicate whether to allow The first base station is connected. The technical solution of the present disclosure can realize establishing a wireless connection between a first base station having only wireless backhaul capability and a second base station having wired backhaul capability, and implementing wireless backhaul.

Wireless backhaul implementation method, device and base station

The present invention relates to the field of wireless communications, and in particular, to an information sending and receiving method, a base station, and a terminal device that are used for uplink timing of a terminal device. In the information sending method, a first base station determines a first time adjustment parameter and a second time adjustment parameter; the first base station sends the first time adjustment parameter and the second time adjustment parameter to a terminal device. According to the solution provided in this application, the base station provides a plurality of time adjustment parameters for the terminal device to perform uplink signal timing, so as to provide flexible and efficient uplink subframe scheduling for the base station, thereby meeting various requirements for uplink timing.

Communication method, base station, and terminal device

A network apparatus may include a memory and processing circuitry configured to receive first connection metrics of a connection with a user equipment that is using a first configuration during a first connected state; receive second connection metrics of the connection with the user equipment during a transition to a second connected state; choose a selected configuration as (i) the first configuration or (ii) a second configuration for the second connection state based on the first connection metrics and the second connection metrics; and send the selected configuration to the user equipment.

User equipment configuration

This application provides a measurement signal configuration method and an apparatus, and relates to the field of communications technologies, to optimize sending or measuring of an SSB in a relay system, so as to avoid a problem that overheads for sending the SSB are excessively high due to node discovery or measurement. This reduces overheads for sending or measuring the SSB by a relay node, and improves resource utilization. The method includes: sending, by a first node, a synchronization signal block SSB at a first candidate location of the SSB, where the synchronization signal block SSB is used by a second node to discover the first node or measure an SSB of the first node, and the first candidate location of the SSB includes a set of candidate locations of SSBs sent by the first node to implement coverage; receiving, by the first node, SSB optimization configuration information, where the SSB optimization configuration information includes an identifier or a number of the SSB; and determining, by the first node, a synchronization signal block SSB sending subset based on the SSB optimization configuration information.
