Technical field

Background technique

In Long Term Evolution (LTE), fifth-generation mobile communication technology (5th-Generation, 5G), and the following wireless communication systems, User Equipment (UE) demands higher speed and stability. The higher. In many scenarios, a repeater transmission is introduced 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. . There are at least three types of network element nodes in the relay communication process, which are base stations, repeaters, and UEs (or other relays). The link between the base station and the repeater is called a backhaul link. , BH), the link between the repeater and the used UE is called an access link (AC). The synchronization signal needs to be transmitted on both the backhaul link and the access link. The following describes the transmission of the synchronization signal.

The synchronization signal is carried on the synchronization signal block, and the time domain resource of one synchronization signal block includes 4 symbols, wherein the first symbol is used for transmitting the primary synchronization signal, and the third symbol is used for transmitting the secondary synchronization signal, the second symbol and The fourth symbol is used to transmit a physical broadcast channel (PBCH), and a part of the resource elements (Resource Element, RE) in the third symbol can also be used to transmit the PBCH. There are at most 2 sync signal blocks in each time slot. As shown in FIG. 1A, each square filled with oblique lines represents a sync signal block, and the squares of two adjacent filled oblique lines are represented in one time slot. 2 sync signal blocks. In addition, the transmission of the synchronization signal block has a period, which is called a synchronization signal block period, and one or more synchronization signal blocks can be transmitted in each synchronization signal block period, and the synchronization signal blocks in any one of the synchronization signal block periods are It is located in a time unit of any one of the sync signal block periods (the time unit is half a radio frame, for example, 5 milliseconds). In the current protocol, the synchronization signal block that can be transmitted in the one time unit has an upper limit. For example, when the subcarrier spacing of the link is 15 kHz, the upper limit of the synchronization signal block that can be transmitted in the time unit is 4 or 8 When the subcarrier spacing of the link is 120 kHz, the upper limit of the sync signal block that can be transmitted in the time unit is 64. However, for the repeater, the repeater needs to receive both the synchronization signal block sent by the backhaul link and the synchronization signal block through the access link, so the number of synchronization signal blocks that the repeater needs to transmit is relatively higher. Many, how to configure the resources for the relay to transmit the sync signal block is a technical problem that those skilled in the art are studying.

For example, assume 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 120 KHz, if the number of synchronization signal blocks that the second device needs to transmit 40 and the number of sync signal blocks that the first device needs to transmit is 30, then the sum of the two is 70 (greater than the upper limit 64 of the sync signal block that can be transmitted in the field), and therefore cannot be transmitted in one sync signal block period. After the 70 sync signal blocks are completed, but the two sync signal block periods can transmit the 70 sync signal blocks, so the second device needs to send the number of sync signal blocks according to the second device and the needs of the device. The at least two sync signal block periods determined by the sum of the number of transmitted sync signal blocks may be specifically two sync signal block periods.

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

In the second optional solution, the at least two synchronization signal block periods are specifically pre-defined in the protocol for several synchronization signal block periods, and the second device is not required to additionally determine according to some information.

Step S402: The second device sends the 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 in the at least two synchronization signal block periods.

Specifically, the first device determines, according to the first synchronization signal block configuration information, the at least two synchronization signal block periods, and a time domain position for transmitting the synchronization signal block on the at least two synchronization signal block periods, and then The synchronization signal block transmitted by the second device is received on at least two synchronization signal block periods. Optionally, the first device may further send the synchronization signal block to the third device on the at least two synchronization signal block periods.

Optionally, there is no quasi co-located (QCL) relationship between the synchronization signal blocks transmitted in the at least two synchronization signal block periods (or “the user does not assume synchronization on the at least two periods” There is a quasi-co-located QCL relationship between signal blocks"). In this way, each synchronization signal block transmitted on the at least two synchronization signal block periods can be recognized by the receiving side as an independent synchronization signal block, and different independent synchronization signal blocks can be transmitted by using different beams. In addition, it is possible that the synchronization signal blocks transmitted in the at least two synchronization signal block periods are not defined to have a quasi co-located (QCL) relationship; or the first synchronization signal block configuration information indication Having no quasi co-located (QCL) relationship between the synchronization signal blocks transmitted in the at least two synchronization signal block periods; or the second device may send the first indication information to the first device, correspondingly The first device receives the first indication information, where the first indication information indicates that there is no quasi-co-located QCL relationship between the synchronization signal blocks transmitted in the at least two synchronization signal block periods.

Optionally, all synchronization signal blocks transmitted on the at least two synchronization signal block periods are jointly numbered, that is, an identifier of any two synchronization signal blocks transmitted during the at least two synchronization signal block periods (or referred to as time) Domain ID) is different. For example, if the at least two sync signal block periods include the sync signal block period 1 and the sync signal block period 2, and there are 64 sync signal blocks transmitted on the sync signal block period 1, on the sync signal block period 2 There are 64 sync signal blocks transmitted, that is, there are 128 sync signal blocks transmitted on the at least two sync signal block periods, and their numbers may be 0 to 127 in order.

Optionally, the synchronization signal block period may be 1/N of an existing synchronization signal block period, and the number of 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, In this way, the time domain resources occupied by the synchronization signal block period in the embodiment of the present application are not increased compared with the prior art, but the number of synchronization signal blocks that can be transmitted is increased a lot, and the transmission synchronization in the communication system is improved. The ability of the signal block.

In the method described in FIG. 4A, the second device directly indicates the time domain resources for transmitting the synchronization signal block on the at least two synchronization signal block periods by using the first synchronization signal block configuration information, which is only relative to the prior art. The manner of indicating the time domain resources for transmitting the synchronization signal block on a synchronization signal block period greatly increases the time domain resources for transmitting the synchronization signal block, and significantly improves the ability to transmit the synchronization signal block in the communication system.

Referring to FIG. 5A, FIG. 5A illustrates a synchronization signal configuration method according to an embodiment of the present invention. The method may be implemented based on the architecture shown in FIG. 2, or may be implemented based on other architectures, including but 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 half a half frame, for example, 5 milliseconds (ms), which is a time period in which the synchronization signal is collectively transmitted. The second synchronization signal block configuration information is used to indicate a time domain resource for transmitting a synchronization signal block on a first time unit in a synchronization signal block period, and a time domain resource for transmitting a synchronization signal block on the second time unit; The length of time of the first time unit and the second time unit may be half a radio frame. The second synchronization signal configuration information indicates that there are many specific manners for transmitting the time domain resource of the synchronization signal block on the second time unit. Optionally, the second synchronization signal configuration information is used to pass the number of the second time unit. And at least one of the number of the synchronization signal blocks and the information of the time domain resources transmitted in the second time unit, to indicate time domain resources for transmitting the synchronization signal block on the second time unit, as exemplified below An optional case is given as an example.

In case 1, the second synchronization signal block configuration information includes the number of second time units, that is, the second time unit is indicated by indicating the number of the second time units. Optionally, the location of the time domain resource used to transmit the synchronization signal block on the second time unit may not be additionally indicated, but the location of the time domain resource on the previous time unit is multiplexed. Optionally, the second device receives, by the first device, the synchronization signal block that is sent by the first device by using the three indication information, and then according to the number of synchronization signal blocks that the second device needs to send and the first device needs The number of the number of synchronization signal blocks transmitted is used to determine the number of the second time units. The general principle is that the larger the number and the larger the number of the second time units. For example, assume 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 120 KHz, if the number of synchronization signal blocks that the second device needs to transmit 40 and the number of sync signal blocks that the first device needs to transmit is 30, then the sum of the two is 70 (greater than the upper limit 64 of the sync signal block that can be transmitted in one time unit), and therefore cannot be transmitted in the first time unit. The 70 sync signal blocks are completed, but the 70 sync signal blocks can be transmitted after adding a second time unit, so it can be determined that the number of the second time units is 1. FIG. 5B illustrates a first time unit and a second time unit in a synchronization signal block period, a total of two time units (each time unit is illustrated by taking 5 milliseconds as an example), wherein each square filled with a diagonal line Represents a time domain resource used to transmit a sync block.

Optionally, the number of the second time units may also be predefined in the protocol. Optionally, the number of synchronization signal blocks that the first device needs to send 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 the second time unit, that is, by indicating the number of the synchronization signal blocks that need to be transmitted in the second time unit Indicates the second time unit. Receiving, by the second device, the synchronization signal block that the first device needs to send by using the third indication information, and then according to the number of synchronization signal blocks to be sent by the second device and the synchronization that the first device needs to send The number of signal blocks is determined to determine the number of sync signal blocks that need to be indicated. The general principle is that the larger the number, the larger the number of sync signal blocks that need to be indicated. For example, assume 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 120 KHz, if the number of synchronization signal blocks that the second device needs to transmit 40 and the number of sync signal blocks that the first device needs to transmit is 30, then the sum of the two is 70 (greater than the upper limit 64 of the sync signal blocks that can be transmitted in the first time unit), so except in the first time unit In addition to the 64 sync signal blocks transmitted, there are 6 left, and the number of indicated sync signal blocks can be 6.

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

In the third case, the second synchronization signal block configuration information includes information of a time domain resource, that is, the second time unit is indicated by indicating a time domain resource for transmitting the synchronization signal block on the second time unit. Receiving, by the second device, the synchronization signal block that the first device needs to send by using the third indication information, and then according to the number of synchronization signal blocks to be sent by the second device and the synchronization that the first device needs to send The sum of the number of signal blocks determines the number of second time units. The general principle is that the larger the number and the larger the time domain resources indicated by the second synchronization signal block configuration information. For example, assume 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 120 KHz, if the number of synchronization signal blocks that the second device needs to transmit 40 and the number of synchronization signal blocks that the first device needs to transmit is 30, then the sum of the two is 70 (greater than the upper limit 64 of the synchronizable signal blocks that can be transmitted in the first time unit), so the second synchronization signal block indicates In addition to indicating the time domain resources used by the first time unit 64 to transmit the synchronization signal block, the information further indicates an additional 6 time domain resources for transmitting the synchronization signal block, that is, by indicating the additional 6 for transmission synchronization. The time domain resource of the signal block implements an indication of the second time unit.

Optionally, the number of time domain resources additionally used by the second synchronization signal block for transmitting the 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.

Case 4: the second synchronization signal block configuration information includes information about a quantity of a second time unit and a time domain resource, where the number of the second time unit is used by the first device to determine a corresponding number of second time units, the time domain The information of the resource is used by the first device to determine a time domain resource for transmitting a synchronization signal block on the second time unit.

Case 5, the second synchronization signal block configuration information includes information about the number of synchronization signal blocks and time domain resources transmitted in the second time unit, and the number of the synchronization signal blocks transmitted in the second time unit is used by The first device determines a corresponding number of second time units, the information of the time domain resource is used by the first device to determine a time domain resource for transmitting a synchronization signal block on the second time unit.

Wherein, scheme 4 and scheme 5 are a scheme in which the number of the second time unit, the number of the synchronization signal blocks transmitted in the second time unit, and the information of the time domain resource are combined, and other schemes in which the information is combined are not here. Let me repeat.

It can be understood that, in the prior art, one time unit is configured in one synchronization signal block period, and only one time unit is transmitted when transmitting different signal blocks, and the present invention is in addition to the one synchronization signal block period. In addition to configuring the one time unit, another second time unit is configured to subsequently transmit the synchronization signal block on the one time unit and the second time unit, which can improve the synchronization signal block transmission capability in one synchronization signal block period.

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

Step S503: The first device receives the second synchronization signal block configuration information sent by the second device.

Step S504: The first device receives the synchronization signal block on the first time unit and the second time unit.

Specifically, the first device parses the second synchronization signal block configuration information, thereby obtaining content indicated by the second synchronization signal block configuration information, and further determining the second time unit, and then in the first time unit and the first A sync signal block is received on the second time unit. The following example is combined with the above case to illustrate how to determine the other at least one time unit.

For the case 1: after the first device determines the number of time units in the second time unit according to the second synchronization signal block configuration information, it can determine that each time unit in the second time unit is used according to a rule defined in the protocol. The time domain resources of the synchronization signal block are transmitted, so that the synchronization signal block can be transmitted on the second time unit according to the time domain resources. For example, after the first device determines that the number of second time units is 3 according to the second synchronization signal block configuration information, the time domain resources of the three time units are further determined, and then the synchronization can be transmitted on the three time units. The signal block is gone.

For Case 2: After the first device determines the number of the synchronization signal blocks that need to be transmitted in the second time unit according to the second synchronization signal block configuration information, the number of required second time units can be determined. For example, the first device needs to further determine that two second time units are needed after determining that the number of synchronization signal blocks transmitted in the second time unit is 80 according to the second synchronization signal block configuration information. Further, the first device may determine, according to a rule defined in the protocol, a time domain resource for transmitting a synchronization signal block in each of the two second time units, and thus may be based on the time domain resources. A synchronization signal block is transmitted on the second time unit.

For the case 3, the first device determines, according to the second synchronization signal block configuration information, that the time domain resource for transmitting the synchronization signal block in the second time unit needs to be determined, and then according to the time domain resources in the second time unit. The sync signal block is transmitted on.

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

Optionally, there is no quasi-co-located QCL relationship between the respective synchronization signal blocks transmitted in the first time unit and the second time unit. In this way, each synchronization signal block transmitted on the first time unit and the second time unit can be recognized by the receiving side as an independent synchronization signal block, and different independent synchronization signal blocks can be transmitted by using different beams. . In addition, it is possible that the first time unit and the synchronization signal block transmitted in the second time unit are not defined to have a quasi co-located (QCL) relationship; and the first synchronization signal block may be The configuration information indicates that there is no quasi co-located (QCL) relationship between the first time unit and the synchronization signal block transmitted in the second time unit; or the second device may send the first device to the first device. An indication information, correspondingly, the first device receives the first indication information, where the first indication information indicates that there is no quasi-co-location QCL relationship between the synchronization signal blocks transmitted in the first time unit and the second time unit .

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

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

Optionally, the second time unit is after the first time unit.

In the method described in FIG. 5A, the second device sends second synchronization signal block configuration information to the first device, the first device according to the second synchronization signal block configuration information in a first time unit within a synchronization signal block period And determining a time domain resource for transmitting the synchronization signal block on the second time unit in the one synchronization signal block period, and determining the transmission synchronization signal block only in the first time unit within the synchronization signal block period compared to the prior art In terms of time domain resources, the time domain resources for transmitting synchronization signal blocks are greatly increased, and the ability to transmit synchronization signal blocks in the communication system is significantly improved.

Referring to FIG. 6A, FIG. 6A illustrates a synchronization signal configuration method according to an embodiment of the present invention. The method may be implemented based on the architecture shown in FIG. 2, or may be implemented based on other architectures, including but 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 in the synchronization signal block period may be half a half frame, for example, 5 milliseconds (ms), which is a time period in which the synchronization signal is collectively transmitted.

Step S602: The first device sends the synchronization signal block in a fourth time unit within a synchronization signal block period of the 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, and the time unit in the synchronization signal block period of the second link is a fourth time unit, a third time unit and a fourth time Units do not overlap in the time domain. The non-overlapping here can include the following possibilities:

Case 1: 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 sync signal block of the second link but the third time unit and the fourth time unit are staggered in the time domain. Optionally, an offset between the third time unit and the fourth time unit is predefined on the first device.

Case 2: There is 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 is an integer multiple of half of the radio frame. Since there is an offset between the synchronization signal block period of the first link and the synchronization signal block period of the second link, there is an offset between the third time unit naturally and the fourth time unit, so the first device receives the The synchronization signal block on the first link is not interfered by the synchronization signal block transmitted on the second link; when the synchronization signal block is transmitted on the second link, it is not synchronized by the transmission on the first link. Signal block interference. For example, if the link between the first device and the second device is a backhaul link (BH), the link between the first device and the third device is an access link (access link, AC). Then, the first device can receive the synchronization signal block from the backhaul link, and can also send 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 are not It will cause interference. 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 within each synchronization signal block period (each time unit is illustrated by taking 5 milliseconds as an example) , wherein each square filled with a diagonal line represents a time domain resource for transmitting a sync signal block.

Optionally, in case 1 or case 2, a second offset exists between the third time unit and the fourth time unit, and the second offset is an integer multiple of a half of a radio frame. Therefore, the 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 the second offset information, where the second offset information may be predefined in the protocol, or may be sent by the second device to the first device. . The following is a scheme for implementing a second offset of the third time unit and the fourth time unit according to the second offset information:

A first possible solution: the information of the second offset includes a start position of each sync signal block period in the sync signal block period of the first link, and each of the sync signal block periods indicating the second link The starting position of the sync signal block period, the two starting positions are staggered, so that the sync signal block period of the first link can be staggered with the sync signal block period of the second link, for example, in timing The upper part is the sync signal block period A, the sync signal block period B, the sync signal block period A, the sync signal block period B, the sync signal block period A, and the sync signal block period B. The synchronization signal block period A is the synchronization signal block period of the first link, and the synchronization signal block period B is the synchronization signal block period of the second link.

In a second possible solution, 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 synchronization signal block period on the first link is in the order of the synchronization signal block period 11, the synchronization signal block period 12, and the synchronization signal block period 13, the synchronization signal block period on the second link is sequentially arranged in time series. For the synchronization signal block period 21, the synchronization signal block period 22, and the synchronization signal block period 23, the offset between the synchronization signal block period 11 and the synchronization signal block period 21 is equal to the first offset, the synchronization signal block period. The offset between the 12 and sync block period 22 is equal to the first offset described above, and the offset between the sync block period 13 and the sync block period 23 is equal to the first offset described above. It can be understood that the first device can obtain the synchronization signal block period on the link between the first device and the second device according to the prior art, and then determine the first combination by combining the second offset. A synchronization signal block period on the link between a device and a third device. In this embodiment, the offset can ensure that the synchronization signal block period of the first link is staggered with the synchronization signal block period of the second link, so the synchronization signal block transmitted on the first link is No interference occurs between the sync signal blocks transmitted on the second link.

In a third possible solution, the information of the second offset includes a start position of a frame period of the second link (such as a position of a 0 frame), so that a start position of the frame period of the second link is An offset exists at a start position of a frame period of a link, and the first device is based on a start position of a frame period of the second link indicated by the information of the second offset, on the second link. Performing data transmission; since there is an offset between the start frame of the first link and the start frame of the second link, the synchronization signal block period of the first link and the synchronization signal block period 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, for example, the timing of the synchronization signal block period A Synchronization signal block period B, synchronization signal block period A, synchronization signal block period B, ... synchronization signal block period A, synchronization signal block period B. The synchronization signal block period A is the synchronization signal block period of the first link, and the synchronization signal block period B is the synchronization signal block period of the second link.

In a fourth possible solution, the information of the second offset includes an offset between a start position of a frame period of the first link and a start position of a frame period of the second link, where the first After the device determines the start position of the frame period of the first link according to the prior art, the start position of the frame period of the second link may be determined by combining the offset, and then the first device uses the second link. The start of the frame period is the reference, and data transmission is performed on the second link. Since there is an offset between the start frame of the first link and the start frame of the second link, there is a natural bias between the synchronization signal block period of the first link and the synchronization signal block period of the second link. The shift amount can ensure that the synchronization signal block period of the first link is staggered with the synchronization signal block period of the second link, for example, the synchronization signal block period A and the synchronization signal block are sequentially sequenced. Period B, sync signal block period A, sync signal block period B, ... sync signal block period A, sync signal block period B. The synchronization signal block period A is the synchronization signal block period of the first link, and the synchronization signal block period B is the synchronization signal block period of the second link.

In the method described in FIG. 6A, the third time unit of the first link for transmitting the synchronization signal block is shifted from the fourth time unit of the second link for transmitting the synchronization signal block, and thus is used for transmission synchronization. The time unit of the signal block is equivalent to doubling with respect to the prior art, greatly increasing the time domain resources for transmitting the sync signal block, and significantly improving the ability to transmit the sync signal block in the communication system.
