Abstract: A synchronization signal/broadcast signal block broadcast method and an apparatus are disclosed. The method includes: A first access network device RAN 1 determines to request a second access network device RAN 2 to perform resource allocation for a terminal; and the RAN 1 sends, to the RAN 2, a first message used to indicate the RAN 2 to broadcast a synchronization signal/physical broadcast channel block SSB. Accordingly, the RAN 2 starts to broadcast the SSB. The first message further includes a broadcast periodicity for the SSB. The broadcast periodicity is further sent by the RAN 1 to the terminal. The RAN 2 stops, based on a specific situation, broadcasting the SSB.

Abstract: This application discloses a reference signal configuration determining method and apparatus. The method includes: A network device determines a first configuration for sending an aperiodic reference signal by a to-be-positioned terminal; and the network device sends the first configuration to a location management function. The network device is a serving base station of a terminal. The serving base station of the terminal may determine an aperiodic reference signal configuration of the terminal at any time. The first configuration of the aperiodic reference signal is sent to the location management function, so that the location management function can be notified of the aperiodic reference signal configuration in time. In this way, the location management function obtains positioning measurement information from a measurement network element based on the first configuration. Consequently, an uplink positioning technology is optimized and uplink positioning accuracy is improved.

Abstract: This application provides a communication method and apparatus, and relates to the field of wireless communication technologies, to reduce energy consumption of UE. In the method, a terminal device may receive, from an access network device, reference signal configuration information and information about an area that are configured for the terminal device. The terminal device may send a reference signal in the area based on the reference signal configuration information. Based on the foregoing solution, the terminal device may send the reference signal in the area based on the reference signal configuration information, so that the terminal device does not need to access a network to reconfigure the reference signal each time the terminal device moves to a new cell, thereby reducing energy consumption of the terminal device.
