In an embodiment of the invention, the network device transmits the identification information of the beam in the cell by the synchronization signal, and uses the identification information of the beam to scramble the corresponding broadcast message of the synchronization signal, and the terminal device. Can acquire the beam identification information by the synchronization signal transmitted by the network device and detect the corresponding broadcast message by the beam identification information. Therefore, the signal transmission method allows a plurality of beam transmission public signals to pass through the cell, thereby acquiring a beamforming gain and finally improving the signal transmission quality.

In the above signal transmission method, the identification information of the first cell can be optionally included in the first broadcast message.

When the cell identification information corresponding to the broadcast message is carried, the terminal device can acquire the cell identification information from the broadcast message, thereby increasing the speed of detecting the cell identification information of the terminal device.

In the above signal transmission method, the first broadcast message may optionally include one or any number or all of the following information: the occupied first radio resource of the first sync signal and the first broadcast message. Relationship information with the occupied second radio resource, identification information of at least one second beam in the first cell, second sync signal transmitted using at least one second beam in the first cell. Information on the occupied third radio resource, the number of beams in the first cell, or information on the occupied fourth radio resource in the second broadcast message transmitted using at least one second beam in the first cell. ..

When the network device includes the above-mentioned at least one kind of information in the first broadcast message transmitted to the terminal device, the terminal device can determine the identification information of at least one second beam by the at least one kind of information. ..

When the network device transmits the identification information of one or more other beams in the first cell to the terminal device in the first broadcast message, the terminal device detects the first broadcast message and then transmits the identification information of the other beam. When the network device can acquire and transmit the information of the occupied resource of the corresponding synchronization signal of the other one or more beams in the first cell to the terminal device in the first broadcast message, the terminal device is the first. After detecting one broadcast message, these synchronization signals are detected based on the resource information of other synchronization signals carried in the first broadcast message, and the identification information of other beams carried on these synchronization signals is further obtained. When the network device can acquire and transmit the information of the resource used for the corresponding broadcast message of one or more other beams in the first cell to the terminal device in the first broadcast message, the terminal device After detecting the first broadcast message, these broadcast messages can be detected by the information of the resources of these broadcast messages, and further, the identification information of the corresponding beam is acquired.

In summary, the network device can carry the related information of the second beam in the transmitted first broadcast message, so that the terminal device can further detect the first broadcast message after detecting the first synchronization signal. Then, the second beam, the second synchronization signal, the second broadcast message, etc. are detected by the first broadcast message. In this way, if the terminal device detects one beam, the information of the other beams can be sequentially acquired, and finally the detection speed for the beam in the cell of the terminal device can be increased.

Optionally, the radio resource information described above may include time domain resource information or frequency domain resource, specifically the location of the time domain resource and / or frequency domain resource used for the sync signal or broadcast message. May be. The relationship information between the sync signal and the resource used in the corresponding broadcast message of the sync signal is specifically in the location of the time domain resource and / or frequency domain resource used in the sync signal and the broadcast message. It may be offset amount information with the position of the used time domain resource and / or frequency domain resource.

Further, when the total number of all forming beams in the first cell is included in the first broadcast message, the terminal device can determine whether or not all the forming beams in the cell have been detected by the information. Further improves the speed of detecting the beam in the cell.

As can be seen from the signal transmission method executed by the terminal device, after the terminal device receives the first synchronization signal transmitted by the network device, the terminal device receives the identification information of the first beam carried on the first synchronization signal. 1 Detect broadcast messages. A specific implementation method in which the terminal device detects the first broadcast message based on the identification information of the first beam carried on the first synchronization signal is as follows.

The terminal device can determine M radio resources to be detected by the set of the occupied radio resource of the first synchronization signal and the first relational information, and then the terminal device can determine the identification information of the first beam. Is used to descramble N broadcast messages on M radio resources to be detected, and the terminal device detects the first broadcast message in K broadcast messages that have been successfully descrambled.

The first relation information set contains M relation information, and the i relation information in the first relation information set is broadcast with the synchronization signal transmitted by the first beam in the i cell in the M cell. Used to indicate the relationship between the message's occupied radio resources, the ith detection target radio resource in the M detection target radio resources and the occupied radio resource of the first synchronization signal. The relationship between is the relationship indicated by the i-th relational information in the first relational information set. In M cells, the first cell is included, M is a positive integer, i is a positive integer less than or equal to M, N is a positive integer less than or equal to M, and K is a positive integer less than or equal to N.

In the signal transmission method, the terminal device identifies the beam in the synchronization signal received from the network device and the resource information used for the synchronization signal, and between the synchronization signal and the resource used for the corresponding broadcast message of the synchronization signal. The corresponding broadcast message of the synchronization signal can be determined by the relationship of.

When K = 1, that is, after the terminal device descrambles N broadcast messages on M radio resources to be detected using the identification information of the first beam, the broadcast successfully descrambled. When the number of messages is one, the terminal device can determine the broadcast message for which the descramble was successful as the first broadcast message.

Selectably, after the terminal device descrambles N broadcast messages on M radio resources to be detected using the identification information of the first beam, the number of broadcast messages successfully descrambled is multiple. That is, K> 1, and when a plurality of cells all transmit a broadcast message on the first beam, the terminal device may have a plurality of broadcast messages that have been successfully descrambled by identifying the first beam. At this time, the relationship information between the broadcast message placed in each of the K broadcast messages for which descramble was successful and the occupied radio resource of the synchronization signal transmitted by the first beam in the cell where the broadcast message is located. Therefore, it is necessary to determine which of the K broadcast messages is the broadcast message corresponding to the first synchronization signal.

Specifically, in the K broadcast messages in which the terminal device has been successfully descrambled, the jth broadcast message is transmitted by the first beam in the cell where the jth broadcast message and the jth broadcast message are located. The relationship information between the scrambled synchronous signal and the occupied radio resource can be carried, and j is a positive integer less than or equal to K. Then, in the K broadcast messages, the relationship information between the privately-occupied radio resource of the broadcast message and the privately-occupied radio resource of the corresponding synchronization signal is the actual state of the broadcast message. When the relationship between the occupied radio resource and the occupied radio resource of the first synchronization signal is the same, the terminal device sets the broadcast message as the first broadcast message. Correspondingly, in the broadcast message transmitted to the terminal device by the network device, the relationship information between the broadcast message and the occupied radio resource of the synchronization signal transmitted by the same beam in the cell where the broadcast message is located is added. Can be placed.

That is, in the embodiment of the present invention, the broadcast message transmitted to the terminal device by the network device is between the broadcast message and the occupied radio resource of the synchronization signal transmitted by the same beam in the cell where the broadcast message is located. When relationship information can be loaded, thereby the same beam corresponds to multiple broadcast messages, the relationship between the sync signal carried in the broadcast message and the resources used in the broadcast message, and the terminal device. The corresponding broadcast message of the sync signal can be determined by the relationship between the sync signal detected by and the resource used for the broadcast message being detected.

In the embodiment of the present invention, the time domain and / or frequency domain position where the synchronization signal is located may be preset. The time domain and / or frequency domain positions where the corresponding sync signals of the different forming beams are located may be different. The time domain and / or frequency domain positions of the sync signals corresponding to the beams having the same beam ID in different cells may be different. The time domain and / or frequency domain positions where the sync signals of different cells and / or different beams are located together constitute one set, which is preset, for example preset to the standard.

Similarly, the time domain and / or frequency domain rate position where the broadcast message is located may be preset. The time domain and / or frequency domain positions where the corresponding broadcast messages of different beams are located may be different. The time domain and / or frequency domain location of the broadcast message corresponding to the beam having the same beam ID in different cells may be different. The time and / or frequency position where the broadcast messages of different cells and / or different beams are located together constitute one set, which is preset, for example preset to the standard.

It should be noted that the time and / or frequency resources used by the broadcast message and the sync signal in the same beam in the same cell do not overlap. Moreover, the relationship between the synchronization signal and the time domain resource and / or the frequency domain resource used for the broadcast message, for example, the offset amount of the time domain and / or the frequency domain position may be preset. The offset amount of all possible time domain and / or frequency domain positions between the sync signal and the broadcast message can constitute one resource relationship set, which is preset.
