Abstract: Example communication methods and apparatus are described. One example communication method includes generating a synchronization signal block (SSB) by an access network device, where the SSB includes a first physical broadcast channel (PBCH) and a second PBCH. The first PBCH carries time-frequency resource position information of first synchronization information, the second PBCH carries time-frequency resource position information of second synchronization information, and a time-frequency resource position of the first synchronization information is different from a time-frequency resource position of the second synchronization information. The access network device broadcasts the SSB. In embodiments of this application, the SSB may carry PBCHs corresponding to terminal devices of different bandwidth types and/or synchronization information of the terminal devices of different bandwidth types to satisfy processing requirements of the terminal devices of a plurality of bandwidth types.

Abstract: The present disclosure provides a method and an electronic device for obtaining location information. Available measurement of a target node and multi-hop nodes in multiple consecutive time slices is obtained. A prediction is performed on the unavailable measurement due to the transmission delay to obtain prediction information. Location information of these nodes in the multiple time slices is obtained based on state variables of the target node and multi-hop nodes in the current time slice and mobility constraints, for reconstructing the trajectory information of these nodes. State information of these nodes in the current time slice is initially estimated based on available measurement to obtain initial state estimation in the current time slice. State estimation of these nodes in the current time slice is obtained by jointly processing the available measurement and the prediction information based on the trajectory constraints and the initial state estimation.
