Abstract: A communication method and device. The method includes: inventory indication information sent by a network device to a terminal device includes information for determining a target terminal device. The inventory indication information indicates that the network device selects the target terminal device to initiate a random access request, or the inventory indication information indicates that the network device supports the target terminal device in initiating a random access request. In this way, the network device may select, based on target terminal devices of different types, or target terminal devices having different capabilities, a target device to perform random access, thereby improving random access efficiency of a second device and performance of subsequent data transmission of the target terminal device.

Abstract: A communication method and system, and a related apparatus. The communication method is applied to the communication system including a first device and a second device. In the communication method, the first device may indicate the second device to reserve a channel resource, and the second device does not perform data transmission on the reserved channel resource. This prevents the second device from occupying channel resources for long time, to release channel resources for a cellular communication system. The first device may schedule a terminal device other than the second device by using the released channel resources. This improves data transmission efficiency.

Abstract: This application discloses a tag positioning method. In this application, a target tag receives first signaling sent by a target reader/writer, where the first signaling includes an identity ID of a first transmitter. The target tag sends second signaling to the target reader/writer, where the second signaling includes the ID of the first transmitter. Further, the target reader/writer may determine, based on the ID that is of the first transmitter and that is included in the signaling sent by the target tag, a coverage area that is of a transmitter and in which the target tag is located, to more accurately determine a location of the tag. Therefore, efficiency of tag positioning is improved.

Abstract: The present disclosure relates to SFN indication methods, terminal devices, and positioning servers and systems. One example method includes obtaining an SFN offset indication parameter of a cell i, sending the SFN offset indication parameter of the cell i to a terminal device, receiving the SFN offset indication parameter of the cell i from the positioning server, obtaining a frame number of a radio frame n of a cell j, and determining a phase rotation parameter of the cell i based on the frame number of the radio frame n of the cell j and the SFN offset indication parameter of the cell i, or obtaining a sequence initialization factor used by a narrowband positioning reference signal (NPRS) on a radio frame m of the cell i, and obtaining the NPRS on the radio frame m of the cell i based on the sequence initialization factor.

Abstract: The present invention relates to the field of wireless communications technologies. In a receiving device, a receiving module receives a synchronization signal including a first signal and a second signal. The first signal includes N1 generalized ZC sequences, and the second signal includes N2 generalized ZC sequences. The second signal is used to distinguish different cells or different cell groups. There are at least two generalized ZC sequences with different root indexes in (N1+N2) generalized ZC sequences. A processing module performs a first sliding correlation operation and a second sliding correlation operation on the synchronization signal, and performs symbol timing synchronization according to a relationship between a sliding correlation peak generated when a sliding correlation is performed on the N1 generalized ZC sequences and a sliding correlation peak generated when a sliding correlation is performed on the N2 generalized ZC sequences.
