Embodiment 1

[0263] This embodiment describes using a subcarrier mapping manner of a synchronization signal at a certain level to indicate whether a synchronization signal block (SS block) where the synchronization signal is located contains a message signal. Wherein, the synchronization signal may include two stages, namely a primary synchronization signal (PSS, Primary Synchronization Signal) and a secondary synchronization signal (SSS, Secondary Synchronization Signal); the SSS sequence may include two subsequences, and the two subsequences adopt a comb-shaped subcarrier cross-mapping method, It is used to indicate the configuration mode of the sync signal block. In this embodiment, the message signal refers to a physical broadcast channel (PBCH).

[0264] In this embodiment, the base station determines the transmission mode of the PBCH; wherein, the PBCH can carry one or more of the following information: system frame number (SFN), index of the synchronization signal block, index of th...

Embodiment 2

[0295] This embodiment describes using a subcarrier mapping manner of a synchronization signal of a certain level to indicate whether a message signal in a synchronization signal block (SS block) is repeatedly sent. Among them, the synchronization signal can include two levels, namely the primary synchronization signal (PSS) and the secondary synchronization signal (SSS); the SSS sequence can include two subsequences, using a comb-shaped subcarrier cross-mapping method, which is used to indicate the configuration of the synchronization signal block. In this embodiment, the message signal refers to a physical broadcast channel (PBCH).

[0296] In this embodiment, the base station determines the transmission mode of the PBCH, that is, whether the PBCH is repeatedly transmitted, such as Figure 11 As shown, there are but not limited to the following repetition methods:

[0297] Repeated transmission in the SS block, for example, time division transmission between two repetitions...

Embodiment 3

[0307] This embodiment describes the use of a subcarrier mapping manner of a synchronization signal at a certain level to indicate the number of times a message signal in a synchronization signal block (SS block) is repeatedly sent. Among them, the synchronization signal can include two levels, that is, the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). The SSS sequence can include three sub-sequences, and the three sub-sequences use a comb-shaped sub-carrier cross-mapping method to indicate the synchronization signal block Configuration method. In this embodiment, the message signal refers to a physical broadcast channel (PBCH).

[0308] In this embodiment, the base station determines the transmission mode of the PBCH, that is, whether the PBCH is repeatedly transmitted, which exists but is not limited to Figure 12 Repeat as shown. Wherein, the number of repeated sending times is a parameter that needs to be indicated in this embodimen...

Abstract

The invention discloses a signal transmission method, device and system. The signal transmission method comprises the step that a base station transmits a synchronization signal block according to a predetermined synchronization signal block configuration mode, wherein the synchronization signal block contains a synchronization signal, or the synchronization signal block contains a synchronizationsignal and a message signal, there is a pre-defined corresponding relation between the synchronization signal and the synchronization signal block configuration mode, and the message signal comprisesat least one of a physical broadcast channel, a paging downlink control message, a paging message, a control channel and a data channel.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a signal transmission method, device and system. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz (megabytes). Hertz) to 3GHz (gigahertz) spectrum resources show an extremely tight situation, which can no longer meet the needs of future wireless communications. [0003] In future wireless communication, carrier frequencies higher than those used in the fourth-generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, 70GHz, etc. This high-frequency channel has relatively low free propagation loss. The shortcomings of large, easily absorbed by oxygen, and greatly affect...
