Description

Synchronization signal configuration method and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a synchronization signal configuration method and a related device.

Background

In Long Term Evolution (LTE), fifth-Generation mobile communication technology (5 th-Generation, 5G) and the following wireless communication systems, User Equipment (UE) has higher and higher requirements for speed and stability. Repeater (real) transmission is introduced in many scenarios to convert a Non Line of Sight (NLOS) channel into a Line of Sight (LOS) channel, thereby improving the stability and throughput of the communication system. In the relay communication process, at least three types of network element nodes exist, which are a base station, a relay and a UE (or other relays), where a link between the base station and the relay is called a backhaul link (BH), and a link between the relay and the UE is called an access link (AC). The transmission of the synchronization signal is required on both the backhaul link and the access link, and the transmission of the synchronization signal will be briefly described below.

The synchronization signal is carried on the synchronization signal block, the time domain Resource of 1 synchronization signal block includes 4 symbols, where the 1 st symbol is used to transmit a primary synchronization signal, the 3rd symbol is used to transmit a secondary synchronization signal, both the 2nd symbol and the 4th symbol are used to transmit a physical broadcast signal (PBCH), and in addition, a part of Resource Elements (REs) in the 3rd symbol may also be used to transmit the PBCH. There are at most 2 sync signal blocks in each slot, and as shown in fig. 1A, each hatched box represents one sync signal block, and two adjacent hatched boxes represent 2 sync signal blocks in one slot. In addition, the transmission of the synchronization signal block has a period, which is called a synchronization signal block period, and 1 or more synchronization signal blocks can be transmitted in each synchronization signal block period, and the synchronization signal block in any one synchronization signal block period is located in a time unit of the any one synchronization signal block period (the time unit is a half radio frame, for example, 5 milliseconds). In the current protocol, there is an upper limit to the number of sync signal blocks that can be transmitted in a time unit, for example, when the subcarrier interval of the link is 15KHz, the upper limit to the number of sync signal blocks that can be transmitted in a time unit is 4 or 8, and when the subcarrier interval of the link is 120KHz, the upper limit to the number of sync signal blocks that can be transmitted in a time unit is 64. However, for the repeater, the repeater needs to receive the synchronization signal block sent by the backhaul link and send the synchronization signal block through the access link, so that the number of the synchronization signal blocks that the repeater needs to transmit is large, and how to configure resources for the repeater to transmit the synchronization signal block is a technical problem that those skilled in the art are studying.

Those skilled in the art will appreciate that the handset configuration shown in fig. 3 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

It is to be understood that the wireless communication system 100 shown in fig. 1B is only for more clearly illustrating the technical solution of the present application, and does not constitute a limitation to the present application, and as the network architecture evolves and new service scenarios emerge, the technical solution provided in the present application is also applicable to similar technical problems.

Referring to fig. 4A, fig. 4A is a synchronization signal configuration method according to an embodiment of the present invention, which may be implemented based on the architecture shown in fig. 1B, or based on other architectures, and the method includes, but is not limited to, the following steps:

step S401: the second device determines first synchronization signal block configuration information.

Specifically, a Synchronization Signal Block (SSB) in the embodiment of the present application may also be referred to as a synchronization signal/physical broadcast channel block (SS/PBCH block), and the synchronization signal block includes a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel for transmitting the synchronization signal and the physical broadcast signal.

The first synchronization signal block configuration information includes synchronization signal block period information indicating at least two synchronization signal block periods, the synchronization signal block periods are periods for transmitting synchronization signal blocks, the periods for transmitting synchronization signal blocks on any one link are continuously distributed in a time domain, a relative position of a time domain resource for transmitting the synchronization signal block in the first period is the same as a relative position of a time domain resource for transmitting the synchronization signal block in the second period, and the first period and the second period are any two periods for transmitting the synchronization signal blocks. For example, the synchronization signal block period information includes an identification of the synchronization signal block period, or includes a time domain range occupied by the synchronization signal block, or includes a time domain offset of the synchronization signal block period with respect to a certain time domain position for reference, and so on. In summary, the synchronization signal block period information enables the first device to determine at least two synchronization signal block periods. In addition, the synchronization signal block period information may indicate a position of a time domain resource used for transmitting the synchronization signal block period in each of the at least two synchronization signal block periods, or indicate a position of a time domain resource used for transmitting the synchronization signal block period in one of the at least two synchronization signal block periods (in this case, a position of a time domain resource used for transmitting the synchronization signal block in a synchronization signal block period other than the one of the at least two synchronization signal block periods is the same as a position of a time domain resource used for transmitting the synchronization signal block in the one synchronization signal block period). In addition, at least two synchronization signal block periods are specifically several, but not limited herein, and fig. 4B illustrates 2 synchronization signal block periods, wherein each hatched square indicates a time domain resource for transmitting a synchronization signal block. Several schemes for determining the period of at least two synchronization signal blocks are exemplified below:

in a first alternative, the second device determines the at least two synchronization signal block periods according to the sum of the number of synchronization signal blocks that the second device needs to transmit and the number of synchronization signal blocks that the first device needs to transmit, and the general principle is as follows: if the sum of the number of the synchronization signal blocks required to be sent by the second device and the number of the synchronization signal blocks required to be sent by the first device is larger, the number of the synchronization signal block periods in the at least two synchronization signal block periods can be set to be larger; if the sum of the number of the synchronization signal blocks that the second device needs to transmit and the number of the synchronization signal blocks that the first device needs to transmit is smaller, the number of the synchronization signal block periods in the at least two synchronization signal block periods may be set smaller. For example, assuming that the subcarrier interval of the link between the second device and the first device and the subcarrier interval between the first device and the third device are both 120KHz, if the number of the synchronization signal blocks that the second device needs to transmit is 40 and the number of the synchronization signal blocks that the first device needs to transmit is 30, the sum of the two is 70 (greater than the upper limit 64 of the synchronization signal blocks that can be transmitted in a half frame), so that the 70 synchronization signal blocks cannot be transmitted in one synchronization signal block period, but two synchronization signal block periods can be used to transmit the 70 synchronization signal blocks, so that at least two synchronization signal block periods determined by the second device according to the sum of the number of the synchronization signal blocks that the second device needs to transmit and the number of the synchronization signal blocks that the first device needs to transmit may be specifically two synchronization signal block periods.

Further, the number of the synchronization signal blocks that the first device needs to transmit may be reported to the second device by the first device through the second indication information, or may be estimated by the second device according to a predefined rule.

In a second alternative, the at least two synchronization signal block periods, in particular several synchronization signal block periods, are predefined in the protocol, and the second device is not required to determine additionally based on some information.

Step S402: the second device transmits first synchronization signal block configuration information to the first device.

Step S403: the first device receives the first synchronization signal block configuration information.

Step S404: the first device receives the synchronization signal block within the at least two synchronization signal block periods.

Specifically, the first device determines the at least two synchronization signal block periods and the time domain positions for transmitting the synchronization signal blocks on the at least two synchronization signal block periods according to the first synchronization signal block configuration information, and then receives the synchronization signal blocks sent by the second device on the at least two synchronization signal block periods. Optionally, the first device may further send a synchronization signal block to the third device over the at least two synchronization signal block periods.

Optionally, the synchronization signal blocks transmitted in the at least two synchronization signal block periods do not have a quasi co-located (QCL) relationship therebetween (or "the user does not assume a quasi co-located QCL relationship between the synchronization signal blocks in the at least two periods"). Thus, each synchronization signal block transmitted in at least two synchronization signal block periods can be identified as an independent synchronization signal block by the receiving side, and different independent synchronization signal blocks can be transmitted by using different beams. In addition, it may be predefined in the protocol that there is no quasi co-located (QCL) relationship between the synchronization signal blocks transmitted in the at least two synchronization signal block periods; it is also possible that the first synchronization signal block configuration information indicates that the synchronization signal blocks transmitted in the at least two synchronization signal block periods do not have a quasi co-located (QCL) relationship therebetween; it is also possible that the second device sends first indication information to the first device, and accordingly the first device receives the first indication information, the first indication information indicating that the synchronization signal blocks transmitted in the at least two synchronization signal block periods do not have a quasi co-located QCL relationship.

Optionally, all the synchronization signal blocks transmitted in the at least two synchronization signal block periods are jointly numbered, that is, the identifiers (or called time domain identifiers) of any two synchronization signal blocks transmitted in the at least two synchronization signal block periods are different. For example, if the at least two synchronization signal block periods include synchronization signal block period 1 and synchronization signal block period 2, and there are 64 synchronization signal blocks transmitted on synchronization signal block period 1 and 64 synchronization signal blocks transmitted on synchronization signal block period 2, i.e., there are 128 synchronization signal blocks transmitted on the at least two synchronization signal block periods, their numbers may be 0 to 127 in sequence.

Optionally, the synchronization signal block period may be 1/N of the existing synchronization signal block period, and the number of the synchronization signal block periods in the at least two synchronization signal block periods is less than or equal to N, where N is greater than 1, so that time domain resources occupied by the synchronization signal block periods in the embodiment of the present application are not increased compared with the prior art, but the number of the synchronization signal blocks that can be transmitted is increased by a large amount, thereby improving the capability of transmitting the synchronization signal blocks in the communication system.

In the method depicted in fig. 4A, the second device indicates, by the first synchronization signal block configuration information, the time domain resources for transmitting the synchronization signal blocks on at least two synchronization signal block periods at a time, which greatly increases the time domain resources for transmitting the synchronization signal blocks and significantly improves the capability of transmitting the synchronization signal blocks in the communication system, compared to the prior art that only indicates the time domain resources for transmitting the synchronization signal blocks on one synchronization signal block period.

Referring to fig. 5A, fig. 5A is a synchronization signal configuration method according to an embodiment of the present invention, which may be implemented based on the architecture shown in fig. 2, or based on other architectures, where the method includes, but is not limited to, the following steps:

step S501: the second device determines second synchronization signal block configuration information.

Specifically, the time length of each time unit in the synchronization signal block period may be a half of a radio frame (half of a millisecond (ms)), for example, 5 milliseconds (ms), and the time unit is a time period for intensively transmitting the synchronization signal. The second synchronization signal block configuration information is used for indicating time domain resources used for transmitting the synchronization signal blocks on a first time unit in a synchronization signal block period and time domain resources used for transmitting the synchronization signal blocks on a second time unit; the time length of the first time unit and the second time unit may be half a radio frame. There are many specific ways for the second synchronization signal configuration information to indicate the time domain resources used for transmitting the synchronization signal blocks in the second time unit, and optionally, the second synchronization signal configuration information is used to indicate the time domain resources used for transmitting the synchronization signal blocks in the second time unit through at least one of the number of the second time units, the number of the synchronization signal blocks transmitted in the second time unit, and information of the time domain resources, which is exemplified by some optional cases below.

Case 1, the second synchronization signal block configuration information includes a number of second time units, i.e., the second time units are indicated by indicating the number of the second time units. Optionally, the location of the time domain resource used for transmitting the synchronization signal block in the second time unit may not be additionally indicated, but the location of the time domain resource in the previous time unit is multiplexed. Optionally, the second device receives synchronization signal blocks that the first device needs to send and are reported by the first device through the three pieces of indication information, and then determines the number of the second time unit according to a sum of the number of the synchronization signal blocks that the second device itself needs to send and the number of the synchronization signal blocks that the first device needs to send, which is roughly based on a principle that the larger the sum of the numbers, the larger the number of the second time unit is. For example, assuming that the subcarrier spacing of the link between the second device and the first device and the subcarrier spacing between the first device and the third device are both 120KHz, if the number of synchronization signal blocks that the second device needs to transmit is 40 and the number of synchronization signal blocks that the first device needs to transmit is 30, the sum of the two is 70 (greater than the upper limit 64 of the synchronization signal blocks that can be transmitted in one time unit), and thus the 70 synchronization signal blocks cannot be transmitted in the first time unit, but in addition, the 70 synchronization signal blocks can be transmitted in a second time unit, and thus the number of the second time unit can be determined to be 1. Fig. 5B illustrates 2 time units (each time unit is illustrated by 5 ms) of a first time unit and a second time unit in a synchronization signal block period, wherein each hatched square represents a time domain resource for transmitting a synchronization signal block.

Optionally, the number of second time units may also be predefined in the protocol. Optionally, the number of synchronization signal blocks that the first device needs to transmit may also be estimated by the second device.

Case 2, the second synchronization signal block configuration information includes the number of the synchronization signal blocks transmitted in a second time unit, i.e. the second time unit is indicated by indicating the number of the synchronization signal blocks that need to be transmitted in the second time unit. The second device receives the synchronization signal blocks that the first device needs to send, which are reported by the first device through the third indication information, and then determines the number of the synchronization signal blocks that need to be indicated according to the sum of the number of the synchronization signal blocks that the second device itself needs to send and the number of the synchronization signal blocks that the first device needs to send, which is roughly the principle that the larger the sum of the number of the synchronization signal blocks that need to be indicated is, the larger the number of the synchronization signal blocks that need to be indicated is. For example, assuming that the subcarrier spacing of the link between the second device and the first device and the subcarrier spacing between the first device and the third device are both 120KHz, if the number of synchronization signal blocks that the second device needs to transmit is 40 and the number of synchronization signal blocks that the first device needs to transmit is 30, the sum of the two is 70 (greater than the upper limit 64 of the synchronization signal blocks that can be transmitted in the first time unit), and thus there are 6 remaining in addition to the 64 synchronization signal blocks transmitted in the first time unit, the number of synchronization signal blocks indicated may be 6.

Optionally, the number of the synchronization signal blocks indicated by the second synchronization signal block configuration information may also be predefined in the protocol. Optionally, the number of synchronization signal blocks that the first device needs to transmit may also be estimated by the second device.

In case 3, the second synchronization signal block configuration information includes information of time domain resources, i.e. the second time unit is indicated by indicating the time domain resources used for transmitting the synchronization signal block on the second time unit. The second device receives the synchronization signal blocks that the first device needs to send, which are reported by the first device through the third indication information, and then determines the number of the second time unit according to the sum of the number of the synchronization signal blocks that the second device itself needs to send and the number of the synchronization signal blocks that the first device needs to send. For example, assuming that the subcarrier spacing of the link between the second device and the first device and the subcarrier spacing between the first device and the third device are both 120KHz, if the number of synchronization signal blocks that the second device needs to transmit is 40 and the number of synchronization signal blocks that the first device needs to transmit is 30, the sum of the two is 70 (greater than the upper limit 64 of the synchronization signal blocks that can be transmitted in the first time unit), so that the second synchronization signal block indication information indicates, in addition to the time domain resources of 64 for transmitting the synchronization signal blocks in the first time unit, 6 additional time domain resources for transmitting the synchronization signal blocks, that is, the indication of the second time unit is implemented by indicating the 6 additional time domain resources for transmitting the synchronization signal blocks.

Optionally, how much of the time domain resource for transmitting the synchronization signal block is additionally indicated by the second synchronization signal block is predefined in the protocol. Optionally, the number of synchronization signal blocks that the first device needs to send is estimated by the second device.

In case 4, the second synchronization signal block configuration information includes the number of second time units and information of time domain resources, where the number of second time units is used by the first device to determine a corresponding number of second time units, and the information of time domain resources is used by the first device to determine time domain resources used for transmitting synchronization signal blocks in the second time units.

In case 5, the second synchronization signal block configuration information includes the number of the synchronization signal blocks transmitted in the second time unit and information of time domain resources, where the number of the synchronization signal blocks transmitted in the second time unit is used by the first device to determine a corresponding number of second time units, and the information of the time domain resources is used by the first device to determine the time domain resources used for transmitting the synchronization signal blocks in the second time units.

Wherein, the schemes 4 and 5 are schemes for combining the number of the second time units, the number of the synchronization signal blocks transmitted in the second time units, and the information of the time domain resources, and other schemes for combining the information are not described herein again.

It can be understood that, in the prior art, one time unit is configured in one synchronization signal block period, and different signal blocks are transmitted only in the one time unit, but the present invention configures another second time unit in the one synchronization signal block period in addition to the one time unit, so as to transmit the synchronization signal blocks in the one time unit and the second time unit subsequently, and can improve the transmission capability of the synchronization signal blocks in the one synchronization signal block period.

Step S502: the second device sends the second synchronization signal block configuration information to the first device.

Step S503: and the first equipment receives the second synchronization signal block configuration information sent by the second equipment.

Step S504: the first device receives a synchronization signal block over the first time unit and the second time unit.

Specifically, the first device parses the second synchronization signal block configuration information to obtain the content indicated by the second synchronization signal block configuration information, further determines the second time unit, and then receives the synchronization signal blocks over the first time unit and the second time unit. The following gives an example of how to determine the further at least one time unit in connection with the above case.

For case 1: after determining the number of time units in the second time unit according to the second synchronization signal block configuration information, the first device may determine, according to rules defined in the protocol, time domain resources for transmitting synchronization signal blocks in each time unit in the second time unit, so that the synchronization signal blocks may be transmitted on the second time unit according to the time domain resources. For example, after the first device determines that the number of the second time units is 3 according to the second synchronization signal block configuration information, the time domain resources of 3 time units are further determined, and then the synchronization signal blocks can be transmitted in the three time units.

For case 2: the first device may determine the number of second time units needed after determining the number of synchronization signal blocks needed to be transmitted in the second time unit according to the second synchronization signal block configuration information. For example, after determining that the number of the synchronization signal blocks transmitted in the second time unit is 80 according to the second synchronization signal block configuration information, the first device further determines that 2 second time units are required. Further, the first device may determine, according to rules defined in the protocol, time domain resources for transmitting the synchronization signal block in each of the 2 second time units, and may thus transmit the synchronization signal block on the second time unit according to the time domain resources.

For case 3, after determining that the time domain resources for transmitting the synchronization signal block in the second time unit need to be determined according to the second synchronization signal block configuration information, the first device may transmit the synchronization signal block in the second time unit according to the time domain resources.

Optionally, the first device may further send a synchronization signal block to the third device over the first time unit and the second time unit.

Optionally, each synchronization signal block transmitted in the first time unit and the second time unit does not have a quasi-co-located QCL relationship. In this way, each synchronization signal block transmitted in the first time unit and the second time unit can be identified as an independent synchronization signal block by the receiving side, and different independent synchronization signal blocks can be transmitted by using different beams. Additionally, it may be predefined in the protocol that there is no quasi co-located (QCL) relationship between the blocks of synchronization signals transmitted in the first time unit and the second time unit; it is also possible that the first synchronization signal block configuration information indicates that there is no quasi co-located (QCL) relationship between the synchronization signal blocks transmitted in the first time unit and the second time unit; it is also possible that the second device sends first indication information to the first device, and accordingly the first device receives the first indication information, the first indication information indicating that there is no quasi co-located QCL relationship between the synchronization signal blocks transmitted in the first time unit and the second time unit.

Optionally, all the synchronization signal blocks transmitted in the first time unit and the second time unit are jointly numbered, that is, the identifiers (or called time domain identifiers) of any two synchronization signal blocks transmitted in the first time unit and the second time unit are different. For example, if the first time unit is time unit 1, the second time unit is time unit 2, and there are 64 sync signal blocks transmitted on time unit 1 and 64 sync signal blocks transmitted on time unit 2, i.e. there are 128 sync signal blocks transmitted on the first time unit and the second time unit, then their numbers may be 0 to 127 in sequence. Optionally, the number L of the second time units satisfies the following relationship:

wherein, S is the time length of the synchronization signal block period, and x is the time length of half a radio frame. For example, if S is 80 ms and x is 5 ms, then L is less than or equal to 16.

Optionally, the second time unit is subsequent to the first time unit.

In the method described in fig. 5, the second device sends the second synchronization signal block configuration information to the first device, and the first device determines the time domain resources for transmitting the synchronization signal block in the first time unit of one synchronization signal block period and the second time unit of the one synchronization signal block period according to the second synchronization signal block configuration information.

Referring to fig. 6A, fig. 6A is a synchronization signal configuration method according to an embodiment of the present invention, which may be implemented based on the architecture shown in fig. 2, or based on other architectures, where the method includes, but is not limited to, the following steps:

step S601: the first device receives the synchronization signal block in a third time unit within the synchronization signal block period of the first link.

Specifically, the first link is a link between the first device and the second device. In addition, the time length of each time unit within the synchronization signal block period, which is a time period for intensively transmitting the synchronization signal, may be half a radio frame (half of a radio frame), for example, 5 milliseconds (ms).

Step S602: the first device transmits the synchronization signal block in a fourth time unit within a synchronization signal block period of a second link.

Specifically, the second link is a link between the first device and a third device. The time unit in the synchronization signal block period of the first link is a third time unit, the time unit in the synchronization signal block period of the second link is a fourth time unit, and the third time unit and the fourth time unit are not overlapped in time domain. The non-overlapping here may include several possible cases as follows:

the first condition is as follows: the synchronization signal block period of the first link is synchronized with the synchronization signal block period of the second link. The first link is synchronized with the synchronization signal block period of the second link but the third time unit and the fourth time unit are staggered in time domain. Optionally, an offset between the third time unit and the fourth time unit is predefined on the first device.

Case two: an offset exists between the synchronization signal block period of the first link and the synchronization signal block period of the second link, and the offset is an integral multiple of half a radio frame. Because the synchronization signal block period of the first link and the synchronization signal block period of the second link have offset, the third time unit naturally has offset with the fourth time unit, so that the first device receives the synchronization signal block from the first link without being interfered by the synchronization signal block transmitted on the second link; when the synchronization signal block is transmitted on the second link, the interference of the synchronization signal block transmitted on the first link is avoided. For example, if the link between the first device and the second device is a backhaul link (BH) and the link between the first device and the third device is an access link (AC), the first device may receive the synchronization signal block from the backhaul link or may transmit the synchronization signal block on the access link, and the process of receiving the synchronization signal block and the process of transmitting the synchronization signal block do not generate interference. Fig. 6B illustrates a synchronization signal block period of the first link and a synchronization signal block period of the second link, and a time unit (each time unit is illustrated by 5 ms) in each synchronization signal block period, wherein each hatched square represents a time domain resource for transmitting a synchronization signal block.

Optionally, in the first or second case, a second offset exists between the third time unit and the fourth time unit, and the second offset is an integer multiple of half of a radio frame, so that an effect that the third time unit and the fourth time unit do not overlap can be achieved. Further, the second offset may be determined according to second offset information, which may be predefined in a protocol or sent to the first device by the second device. Several schemes for implementing the second offset of the third time unit and the fourth time unit according to the second offset information are listed below:

a first possible solution: the information of the second offset includes a start position of each of the synchronization signal block periods of the first link and a start position indicating each of the synchronization signal block periods of the second link, which are staggered, so that the synchronization signal block periods of the first link and the synchronization signal block periods of the second link are staggered, for example, a synchronization signal block period a, a synchronization signal block period B … …, a synchronization signal block period a, and a synchronization signal block period B are sequentially arranged in time. The synchronization signal block period a is a synchronization signal block period of the first link, and the synchronization signal block period B is a synchronization signal block period of the second link.

In a second possible scenario, the information of the second offset includes a first offset between a synchronization signal block period on the first link and a synchronization signal block period on the second link, for example, if the sync signal block period on the first link is sequentially arranged as sync signal block period 11, sync signal block period 12, and sync signal block period 13, the sync signal block periods on the second link are sequentially arranged as sync signal block periods 21, sync signal block periods 22, sync signal block periods 23, then the offset between the sync signal block periods 11 and the sync signal block periods 21 is equal to the first offset, the offset between the synchronization signal block period 12 and the synchronization signal block period 22 is equal to the first offset mentioned above, the offset between the sync signal block period 13 and the sync signal block period 23 is equal to the first offset. It is understood that the first device may obtain the synchronization signal block period on the link between the first device and the second device in the manner of the prior art, and then determine the synchronization signal block period on the link between the first device and the third device by combining the second offset. In the embodiment of the present application, the offset may ensure that the synchronization signal block periods of the first link are staggered with the synchronization signal block periods of the second link, so that no interference occurs between the synchronization signal blocks transmitted on the first link and the synchronization signal blocks transmitted on the second link.

In a third possible scheme, the information of the second offset includes a start position (e.g., a position of 0 frame) of a frame period of the second link, so that the start position of the frame period of the second link is offset from the start position of the frame period of the first link, and the subsequent first device performs data transmission on the second link based on the start position of the frame period of the second link indicated by the information of the second offset; because there is an offset between the start frame of the first link and the start frame of the second link, there is naturally an offset between the synchronization signal block period of the first link and the synchronization signal block period of the second link, and the offset can ensure that the synchronization signal block period of the first link and the synchronization signal block period of the second link are staggered, for example, the synchronization signal block period a, the synchronization signal block period B … …, the synchronization signal block period a, and the synchronization signal block period B are sequentially in sequence. The synchronization signal block period a is a synchronization signal block period of the first link, and the synchronization signal block period B is a synchronization signal block period of the second link.

In a fourth possible scheme, the information of the second offset includes an offset between a starting position of a frame period of the first link and a starting position of a frame period of the second link, the first device determines the starting position of the frame period of the first link according to the prior art, and then determines the starting position of the frame period of the second link by combining the offset, and then the first device performs data transmission on the second link with the starting position of the frame period of the second link as a reference. Because there is an offset between the start frame of the first link and the start frame of the second link, there is naturally an offset between the synchronization signal block period of the first link and the synchronization signal block period of the second link, and the offset can ensure that the synchronization signal block period of the first link and the synchronization signal block period of the second link are staggered, for example, the synchronization signal block period a, the synchronization signal block period B … …, the synchronization signal block period a, and the synchronization signal block period B are sequentially in sequence. The synchronization signal block period a is a synchronization signal block period of the first link, and the synchronization signal block period B is a synchronization signal block period of the second link.

In the method depicted in fig. 6A, the third time unit for transmitting the synchronization signal block of the first link is staggered from the fourth time unit for transmitting the synchronization signal block of the second link, so that the time unit for transmitting the synchronization signal block is doubled compared with the prior art, the time domain resource for transmitting the synchronization signal block is greatly increased, and the capability of transmitting the synchronization signal block in the communication system is significantly improved.
