摘要： A message transmission method and device relating to the field of communications technologies is disclosed, so as to improve an anti-interference capability in message transmission. The method includes: generating, by a base station, a scrambling code according to a first time parameter; then scrambling a system message according to the scrambling code; and finally sending the scrambled system message to a terminal on a physical broadcast channel. In this technical solution, because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

摘要： This application provides a system message transmission method, an apparatus, and a system. A first communications device configures a MIB message, and the MIB message may carry various different information used to transmit a SIB1, for example, any one or more of scheduling information, first information, and an operation mode of a carrier, so that a second communications device receives the SIB1 based on the MIB message. The first communications device may flexibly configure information used to transmit the SIB1.In addition, when configuring the MIB message, the first communications device may consider ensuring, through configuration or implicit indication, that resource locations for transmitting SIB1s of different cells in one period are different. This type of interference isolation mechanism can avoid mutual interference between SIB1s of different cells, so that transmission reliability of the SIB1s can be improved.

摘要： The present invention discloses an SFN indication method, a terminal device, and a positioning server and system, and relates to the communications field, so as to avoid erroneous determining caused because phase rotation cannot be distinguished when a phase rotation sequence is detected. The SFN indication method includes: obtaining, by a positioning server, an SFN offset indication parameter of a cell i; sending, by the positioning server, the SFN offset indication parameter of the cell i to a terminal device; receiving, by the terminal device, the SFN offset indication parameter of the cell i from the positioning server; obtaining, by the terminal device, a frame number of a radio frame n of a cell j; and determining, by the terminal device, 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 of the cell i. Embodiments of the present invention are applied to OTDOA positioning.

摘要： According to a communication method, a network-side device, and a communications system, a D2D connection is established between a master terminal located within network coverage and a slave terminal located beyond the network coverage, and a common communication connection is established between the master terminal and a network-side device, so that indirect communication can be implemented between the slave terminal located beyond the network coverage and the network-side device by using the master terminal. In addition, when the connection is established between the master terminal and the network-side device, service type information reflecting a data packet reported by the slave terminal (or a data packet delivered by the network-side device and received by the slave terminal) is sent to the network-side device, so that the network-side device can learn that a current communication process is not a process of common communication with the master terminal, but is a process of indirect communication with the slave terminal located beyond the network coverage, which avoids a problem of a communication failure caused by that the network-side device performs communication according to a common communication process.
摘要翻译：根据通信方法，在位于网络覆盖范围内的主终端和位于网络覆盖范围之外的从属终端之间建立网络侧设备和通信系统之间的D2D连接，并且在主设备之间建立公共通信连接终端和网络侧设备，使得可以通过使用主终端在位于网络覆盖范围之外的从属终端和网络侧设备之间实现间接通信。另外，当在主终端与网络侧设备之间建立连接时，反映由从终端报告的数据分组（或由网络侧设备发送并由从终端接收的数据分组）的业务类型信息，被发送到网络侧设备，使得网络侧设备可以了解当前的通信过程不是与主终端的公共通信过程，而是与位于网络之外的从属终端进行间接通信的过程覆盖，其避免了因网络侧设备根据公共通信处理进行通信而引起的通信故障的问题。
