Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application.

In 5G technology, because the successful location of the base station LBT (Listen Before Talk) on the unlicensed spectrum is unpredictable, and if the LBT fails, it is likely to cause the base station to fail to send the SSB, and it may also cause the terminal The device failed to receive the SSB. In NR-U, an SSB is sent at a candidate location. A candidate location may be used to send an SSB or may not send an SSB. Therefore, multiple candidate locations sent by the SSB can be provided, and the number of candidate locations provided It is greater than the maximum number of SSBs to be sent, so that after the LBT is successful, there are still enough candidate positions for the base station to send the SSB, and accordingly to avoid the impact of the LBT failure on the terminal equipment receiving the SSB, as shown in Figure 1. For example, if the base station sends a maximum of 8 SSBs in a transmission period, more than 8 candidate positions can be configured. For example, 20 candidate positions for SSB transmission can be pre-configured, and a maximum of 8 can be transmitted from these 20 candidate positions for SSB transmission. SSB. Among them, as shown in Figure 1, the candidate position is a position in the time domain.

As in the configured candidate positions, some candidate positions may be sent by SSB, and some candidate positions may not be sent by SSB. If all candidate positions are used as candidate positions for SSB transmission, the terminal equipment cannot perform rate matching well. , And also cause a waste of available resources. Therefore, the terminal device can determine which candidate positions will not be sent by SSB among all the candidate positions configured, and which candidate positions may be sent by SSB, so as to facilitate the UE to respond to those who may be sent by SSB. Candidate positions are rate-matched, and candidate positions that are not sent by SSB are used to transmit other information, such as physical downlink control channel (PDCCH, Physical Downlink Control CHannel), physical downlink shared channel (PDSCH, Physical Downlink Shared CHannel), or others Reference signals (RS, Reference Signals), such as channel state information reference signal (CSI-RS, Channel-State Information Reference Signal), demodulation reference signal (DMRS, DeModulation Reference Signal), tracking reference signal (TRS, tracking reference signal) , Phase tracking reference signal (PTRS, phase noise tracking RS), etc.

Therefore, the inventor proposes the method for determining the resource occupied position in the embodiment of the present application, which is used for the terminal device to determine the candidate positions for SSB transmission in the unlicensed frequency band, and correspondingly, it can simultaneously determine that all candidate positions are not. The location where the SSB is sent.

The first embodiment

Fig. 2 shows the method for determining the resource occupation position provided by the first embodiment of the present application. This method can be applied to terminal equipment. Specifically, the method includes:

Step S110: Obtain location configuration information, where the location configuration information includes the configuration of the base station for the candidate location for transmitting the synchronization signal block.

The base station may send location configuration information to the terminal device, and the location configuration information may be a kind of indication information (index) used to notify the terminal device of the configuration of the base station for the candidate location for transmitting the synchronization signal block. The terminal device can obtain the location configuration information to determine the transmission status of the synchronization signal block at each candidate location, that is, determine at which candidate locations the base station may send the synchronization signal block to the terminal device, and at which candidate locations the base station will not send the synchronization signal block to the terminal device Send the sync signal block. In the candidate locations where the base station may send the synchronization signal block, the terminal device may receive the synchronization signal block, and in the candidate location where the base station is impossible to send the synchronization signal block, the terminal device may not receive the synchronization signal block.

Step S120: According to the position configuration information, determine the resource occupied positions in all candidate positions in the synchronization signal block transmission window, where the candidate positions are the positions used to transmit the synchronization signal block.

According to the position configuration information, among all candidate positions in each transmission window of the synchronization signal block, candidate positions for the synchronization signal block may be determined, and the candidate positions for the synchronization signal block may be sent as the resource occupation position. It is understandable that the candidate position is the position used to transmit the synchronization signal block, for the base station, it is the position used to send the synchronization signal block, and for the terminal device, it is the position where the synchronization signal block is received.

In the embodiment of the present application, according to the location configuration information that reflects the configuration of the candidate location sent by the base station, the candidate location in the transmission window where the synchronization signal block may be transmitted may be determined as the determined resource occupation location.

Second embodiment

This application also provides an embodiment, which describes a specific way of determining the resource occupation location. In this embodiment, according to the arrangement relationship of a group of candidate positions, it can be determined that among all the candidate positions in the synchronization signal transmission window, the candidate position corresponding to the transmittable candidate position is the resource occupied position. Specifically, in this embodiment, as shown in FIG. 3, it may include:

Step S210: Receive location configuration information, where the location configuration information includes: among a set of candidate locations used by the base station to transmit synchronization signal blocks, the arrangement relationship between candidate locations that can transmit synchronization signal blocks and candidate locations that cannot transmit synchronization signal blocks .

The position configuration information may include an arrangement relationship between the candidate positions of the transmittable synchronization signal block and the candidate positions of the untransmissible synchronization signal block among a set of candidate positions for transmitting the synchronization signal block. Among them, the candidate positions where the synchronization signal block can be transmitted are the candidate positions where the synchronization signal block may be transmitted, and the candidate position where the synchronization signal block cannot be transmitted is the candidate position where the synchronization signal block will not be transmitted. Each candidate position in the set of candidate positions is adjacent in the time domain. Among them, the candidate position where the synchronization signal block may be sent indicates that within a transmission period, if the LBT is successful and the synchronization signal block corresponding to the candidate position has not been transmitted, the base station will transmit the corresponding synchronization signal block at the candidate position.

Among them, the base station can use a bitmap as the location configuration information, and send the configuration of a group of candidate locations in the form of a bitmap. Each bit in the bitmap represents a candidate location, and the number of valid bits in the bitmap It is the number of candidate positions in a group of candidate positions, or the length of the bitmap is expressed as the number of candidate positions in a group of candidate positions. In addition, in the bitmap, one of 0 or 1 may be used to indicate a candidate position of a synchronization signal block that may be transmitted, and the other may indicate a candidate position of a synchronization signal block that will not be transmitted. The arrangement of 0 and 1 represents the arrangement relationship between the candidate positions of a group of candidate positions that can transmit a synchronization signal block and the candidate positions that cannot transmit a synchronization signal block. For example, in the bitmap, 1 represents the candidate position of the synchronization signal block that may actually be sent, and 0 represents the candidate position of the synchronization signal block that will not be sent. The candidate position of the synchronization signal block that can be transmitted and the position of the synchronization signal block can be determined according to the arrangement of 1 and 0. The arrangement relationship between the candidate positions of the non-transmissible sync signal block.

For example, the bitmap indicating the configuration of a group of candidate positions in the configuration information is 1101, which means that in a group of candidate positions, the first, second, and fourth candidate positions may have corresponding SSB transmissions. The candidate position will not have the corresponding SSB sent.

Optionally, in this embodiment of the present application, valid configuration information in the location configuration information may also be determined. After the effective configuration information is determined, when determining the resource occupation positions in all candidate positions in the synchronization signal block transmission window according to the location configuration information, all candidates in the synchronization signal block transmission window may be determined according to the effective configuration information The resources in the location occupy the location. That is to say, in the manner of determining the resource occupation location described in the embodiment of the present application, the location configuration information on which it is based is the determined effective configuration information.

In the embodiment of the present application, in the received location configuration information, if the number of candidate locations in a group is greater than the value Q of the quasi co-location parameter, the first Q candidate locations in the location configuration information can be used as valid location configuration information ; Or, use the last Q candidate positions in the position configuration information as valid position configuration information; or use the position configuration information as valid configuration information. The quasi co-location parameter is used to determine the quasi co-location relationship between candidate positions in the transmission window, and the quasi co-location parameter Q is a positive integer.

For example, the location configuration information is a bitmap, and if the length of the bitmap is greater than the value Q of the quasi co-location parameter, the bitmap is used as the effective configuration information; or the first Q bits of the bitmap are used as the effective configuration information ; Or use the last Q bits of the bitmap as valid configuration information.

Step S220: cyclically expand the arrangement relationship to all candidate positions in the transmission window.

Step S230: Determine one or more candidate positions that can transmit synchronization signal blocks among all the expanded candidate positions as the resource occupied positions.

In the embodiment of the present application, the transmittable candidate positions among all the candidate positions in the transmission window can be determined according to the expansion of the arrangement relationship in a set of candidate positions, and the transmittable candidate positions are candidate positions where the synchronization signal block may be transmitted.

Specifically, K represents the number of all candidate positions in the transmission window, and K is a positive integer, then the cyclic expansion is that the arrangement relationship of a group of candidate positions in the position configuration information is cyclically expanded among the K candidate positions, so as to realize K Each of the candidate positions corresponds to a candidate position where a synchronization signal block is likely to be transmitted or a position where it is impossible to transmit a synchronization signal block, so that one or more transmittable candidates among the K candidate positions after expansion can be determined Location is the location occupied by the resource.

For example, the position configuration information is represented by a bitmap, 1 corresponds to the candidate position that may transmit the synchronization signal block, 0 corresponds to the candidate position that does not transmit the synchronization signal block, the effective length of the bitmap is L bits, when there are K candidates in the transmission window In the position, the position configuration information of L bits is extended to K candidate positions. In other words, the L bits are expanded to K bits, and the candidate position corresponding to 1 after the expansion is determined as the resource occupation position.

As shown in Figure 4, assuming that the position configuration information is 11010101 and there are 20 candidate positions in the transmission window of the synchronization signal block, the position configuration information is cyclically expanded to 20 candidate positions, which is expanded to 11010101 11010101 1101. Among them, 1 corresponds to a candidate position where a synchronization signal block may be transmitted, and 0 corresponds to a candidate position where a synchronization signal block is not transmitted. Then, among the expanded 20 candidate positions, the candidate position corresponding to 1 can be determined as a resource-occupied position, and the candidate position corresponding to 0 is a non-resource-occupied position. There is no SSB transmission and can be used to transmit other information.

In the embodiment of the present application, the arrangement relationship of candidate positions in the location configuration information is cyclically extended to all candidate positions in the transmission window, so that the resource occupation positions in all candidate positions in the transmission window can be determined according to the arrangement relationship.

The third embodiment

When two reference signals (such as synchronization signal blocks) have a quasi co-located (QCL) relationship, it can be considered that the large-scale parameters of the two reference signals (such as Doppler delay, average delay, Spatial reception parameters, etc.) can be inferred from each other, or can be considered similar. Correspondingly, candidate locations with a quasi co-location relationship can transmit the same synchronization signal block. Therefore, this application also provides an embodiment for determining the synchronization signal transmission window based on the arrangement relationship of a group of candidate locations Among all candidate positions in, the candidate position corresponding to the transmittable candidate position is the resource occupied position. Specifically, in this embodiment, the resource occupation location can be determined according to the quasi co-location relationship. As shown in Figure 5, the method provided by the embodiment of the present application includes:

Step S310: Acquire location configuration information, where the location configuration information includes: among a set of candidate locations used by the base station to transmit synchronization signal blocks, the ranking between candidate locations that can transmit synchronization signal blocks and candidate locations that cannot transmit synchronization signal blocks Cloth relationship.

The configuration of the candidate positions of the synchronization signal block transmitted by the base station may include the arrangement relationship of the candidate positions therein, so that the arrangement relationship can be obtained according to the position configuration information. For the specific description of this step, please refer to the foregoing embodiment, which will not be repeated here.

Step S320: According to the arrangement relationship, among all candidate positions in the synchronization signal transmission window, a candidate position having a quasi co-location relationship with the transmittable candidate position is determined to be the resource occupation position, and the transmittable candidate position is The position of the sync signal block can be transmitted.

Among all the candidate positions in a transmission window, there may be candidate positions with a quasi co-location relationship. Therefore, it is possible to determine the candidate positions in which there is a quasi co-location relationship.

Wherein, the quasi-co-location relationship can be determined according to the quasi-co-location parameter, and the quasi-co-location parameter can be a positive integer, which is represented by Q in the embodiment of the present application. The terminal equipment can obtain the quasi co-location parameters from the base station.

In addition, all candidate positions in the transmission window can be correspondingly numbered, and the terminal device can obtain the number from the base station or in a manner predefined by the protocol.

If the number of the two candidate positions is the same as the value obtained by modulating Q, it can be determined that the two candidate positions have a quasi co-location relationship. For example, the numbers of the two candidate positions are M1 and M2 respectively. If M1 mod Q is equal to M2 mod Q, the two candidate positions are considered to have a quasi co-location relationship. Or, for example, as shown in Figure 6, the value of Q is 8, and the numbers corresponding to the SSBs with candidate positions of 0, 8, and 16 are all 0 after the modulus of Q. It can be determined that the candidate positions are 0, 8, and 16. The candidate locations have a quasi co-location relationship.

In the embodiment of this application, the candidate position that has a quasi co-location relationship with the transmissible candidate position may be, if the number of the candidate position is aligned with the value obtained after the modulus of the co-location parameter, it is compared with the transmissible candidate in a group of candidate positions. If the location corresponds to the location, it is determined that the candidate location is a candidate location that has a quasi co-location relationship with the transmittable candidate location.

Specifically, when determining the candidate positions that have a quasi co-location relationship with the transmittable candidate positions among all the candidate positions in the synchronization signal transmission window, the number of all candidate positions in the transmission window may be obtained. Calculate all the numbers, align the modulo values of the co-location parameters to obtain multiple modulus values. Among the multiple modulus values, the modulus value corresponding to the arrangement position of the transmittable candidate position in the arrangement relationship is determined, and the candidate position corresponding to the determined modulus value is used as a candidate having a quasi co-location relationship with the transmittable candidate position position. The transmittable candidate position is a candidate position where a synchronization signal block can be transmitted, that is, a candidate position where a synchronization signal block may be transmitted.

Among them, the correspondence between the modulus value and the arrangement position can be understood as the modulus value obtained by the number of the first candidate position among all the K candidate positions in the transmission window, including the 1st to Kth candidate positions, Correspond to the first candidate position in the arrangement relationship; the modulus value obtained by the number of the second candidate position corresponds to the second candidate position in the arrangement relationship, and so on, until the number of the Lth candidate position is obtained The modulus value corresponds to the Lth candidate position in the arrangement relationship. Among them, the arrangement relationship includes a group of L candidate positions.

For example, as shown in Figure 7, suppose the location configuration information is 1101 and the quasi co-location parameter is 4. The candidate position equal to 0 after the number and 4 modulo corresponds to the first 1 in the position configuration information; the candidate position equal to 1 after the number modulo 4 corresponds to the second 1 in the position configuration information; the number modulo 4 The candidate position that is equal to 3 corresponds to the fourth 1 in the position configuration information, and the terminal device can determine that the number and 4 are modulo 0 (

numbers

0, 4, 8, 12, 16 in Figure 7), number After modulo 4, it is equal to 1 (

numbers

1,5,9,13,17 in Figure 7) and number and 4 are modulo 3 (

numbers

3,7,11,15,19 in Figure 7) The candidate position of is the resource occupied position.

Optionally, in the transmission window, for the Xth candidate position, X is used as the ranking position of the candidate position in the transmission window in the time domain. The number corresponding to the Xth candidate position can be the last three digits of X. For example, X is 9 (decimal), which is 1001, then the number of the corresponding candidate position is 001, which is 1 in decimal. In addition, optionally, the number corresponding to the Xth candidate position may also be X, for example, if X is 9, then the corresponding number is 9. Optionally, as shown in FIG. 7, the candidate position in the transmission window may start from the 0th position, and X may start from 0 to (K-1).

In the embodiment of the present application, the ranking position X of the candidate position is mainly used as an example for illustration. Of course, if the candidate position numbers are in other forms, such as the last three digits of the sorted position X, then the sorted position is the candidate position of X. When Q is taken modulo Q, the latter three digits are taken modulo Q. For example, for the 9th candidate position in FIG. 7 (ie, the candidate position corresponding to the number 9 in FIG. 7), if the last three digits of 9 are used as the number, since the binary number of 9 is 0001, the next three digits 001 modulate Q.

In the embodiment of the present application, a candidate location that has a quasi co-location relationship with a transmissible candidate location can be determined as a resource-occupied location based on the quasi-co-location parameter, which improves the determination speed of the resource-occupied location.

Fourth embodiment

Since the base station has a higher possibility of transmitting the synchronization signal block when the channel is preempted, this application also provides an embodiment, which can determine from the candidate position in the transmission window when it is determined that the base station has preempted the channel The resource occupancy position, so that the determined resource occupancy position is more accurate. Specifically, referring to FIG. 8, the method of this embodiment includes:

Step S410: Obtain location configuration information, where the location configuration information includes the configuration of the base station for the candidate location for transmitting the synchronization signal block.

Step S420: In the transmission window, when the indication information sent by the base station is received, a reference position is determined according to the indication information, and the indication information indicates that the base station has seized the channel.

The indication information is information that can indicate that the base station has seized the channel, for example, it can be COT indication, DCI message (carried on PDCCH or GC-PDCCH), or other reference information (such as SSB, CSI-RS, TRS, DMRS), etc. . Optionally, in this embodiment of the application, any information sent from the base station can be used as the indication information.

After receiving the indication information, a reference position may be determined according to the indication information. The reference position is a time domain position for determining whether to confirm the resource occupation position for the candidate position after the reference position.

In an implementation manner, in this embodiment of the present application, the time at which the indication information is received may be directly used as the reference position.

In another implementation manner, the location where the synchronization signal block is sent may be set with certain preset conditions, such as sending at an even-numbered position, sending at a position that is a multiple of 4, and sending at a position that is a multiple of 8. Therefore, in the embodiment of the present application, the nearest candidate position that satisfies the preset condition after the time when the indication information is received may be obtained as the reference position.

Among them, in the transmission window, all candidate positions can be grouped, starting from the first candidate position, after each adjacent L grouping of the candidate positions in the transmission window, the final candidate positions less than L are grouped into one group, two groups The boundary between is defined as the group boundary. Where L is the number of a group of candidate positions indicated in the position configuration information. Optionally, in this embodiment of the present application, the candidate position that meets the preset condition may be the first candidate position after the group boundary.

In addition, optionally, in the embodiment of the present application, the candidate positions that meet the preset conditions may also be candidate positions numbered even; or candidate positions numbered as multiples of 4; or candidate positions numbered as multiples of 8. Or the nearest candidate position after the indication information, etc., can be set as needed.

Among them, the candidate position numbered even; or the candidate position numbered as a multiple of 4; or the candidate position numbered as a multiple of 8 can be calculated according to the formula, which can be X mod G=0, which means in the transmission window, such as As mentioned above, the Xth candidate position represents the candidate position numbered X, and the value of G can be set according to a preset condition. For example, if the candidate position that meets the preset condition is a candidate position with an even number, then the value of G If the candidate position that meets the preset condition is a candidate position that is a multiple of 4, then the value of G is 4; if the candidate location that meets the preset condition is a candidate position that is a multiple of 8, then the value of G is The value is 8; if the candidate position that meets the preset condition is the nearest candidate position after the indication information, the value of G is 1. Among them, G can be determined in one of the following ways: broadcast messages, including MIB, SIB1 (RMSI), and SIB; RRC proprietary signaling; pre-arranged by the protocol.

Step S430: According to the position configuration information, determine the resource occupation position from the candidate position after the reference position.

In the embodiment of the present application, when determining the resource occupation positions in all candidate positions in the synchronization signal block transmission window according to the position configuration information, the position configuration information may be determined from the candidate positions after the reference position Resource occupation location. That is, after the reference position is determined, the resource occupation position is determined from the candidate position after the reference position.

In the embodiment of the present application, if the reference position itself is a candidate position, the candidate position after the reference position may include the reference position itself, and the candidate position between the reference position and the group boundary may include the reference position itself. Of course, if the reference position itself is a candidate position, the candidate position after the reference position may not include the reference position, and the candidate position between the reference position and the group boundary may not include the reference position itself, which can be specifically set according to requirements.

The embodiment of the present application mainly uses the time when the indication information is received as the reference position as an example to describe the determination of the resource occupation position.

In the embodiment of the present application, determining the resource occupation position from the candidate position after the reference position may be to use all candidate positions after the reference position as the resource occupation position; or, to use all the candidates for the synchronization signal block that may be transmitted after the reference position The positions are all taken as resource occupied positions; or, the resource occupied positions are determined from a designated number of candidate positions after the reference position, and the designated number can be determined according to the reference position and the number of a set of candidate positions.

The following describes the designated number of candidate positions after the reference position through different implementation manners to determine the resource-occupied position.

In the first implementation manner, the location configuration information may include the number L of a group of candidate locations used by the base station to transmit the synchronization signal block, where L is a positive integer. Among all candidate positions of the synchronization signal block in the transmission window, every adjacent L candidate positions may be grouped into a group, and finally, candidate positions that do not satisfy the number L are grouped into a group. Take the boundary between the two groups as the group boundary.

In this embodiment, when the resource occupation position is determined from the candidate position after the reference position according to the position configuration information, the group boundary closest to the reference position may be determined, and the group boundary is determined from the reference position and the group Among the candidate positions between the boundaries and the nearest L candidate positions after the group of boundaries, one or more candidate positions are determined as resource-occupied positions.

In this embodiment, a bitmap is used as an example of location configuration information to describe grouping. The effective length of the bitmap is L. If the value of L is 8, the grouping of every L candidate positions in the transmission window can be as shown in Fig. 9, because the last 4 candidate positions (that is, the numbered 16 to 19 in Fig. 9 Candidate positions) do not meet 8, then the 4 candidate positions are grouped into one group. In the grouping shown in FIG. 9, the group boundary is between 7 and 8, and the group boundary is between 16 and 16. Optionally, according to needs, in this embodiment of the application, before the first candidate position and after the last candidate position in the transmission window can also be used as group boundaries, as shown in Figure 8 before the candidate position numbered 0 and the candidate numbered 19 After the location. The first number information in FIG. 9 is the number of the candidate position.

After the reference position is determined, the group boundary closest to the reference position can be determined, that is, after the time of the reference position and the group boundary closest to the time of the reference position. As shown in FIG. 10, the time corresponding to the indication information is the reference position. With reference to FIG. 9, the group boundary with the closest reference position is between 7 and 8.

In this embodiment, one or more candidate positions can be determined as resource-occupied positions from candidate positions between the reference position and the nearest group boundary, and L candidate positions after the nearest group boundary.

Optionally, in this embodiment, the candidate positions between the reference position and the nearest group boundary, and the L candidate positions after the nearest group boundary may be used as resource occupation positions. For example, as shown in Figure 10, the candidate positions numbered 5 to 7 are the candidate positions between the reference position and the nearest group boundary, and the candidate positions numbered 8 to 15 are the L candidate positions after the nearest group boundary, and the number 5 to The candidate positions numbered 7 and numbered 8 to 15 are all determined to be resource-occupied positions.

Optionally, in this embodiment, the candidate positions between the reference position and the nearest group boundary, and among the L candidate positions after the nearest group boundary, candidate positions that may transmit synchronization signal blocks may be used as resource occupation positions .

The location configuration information may include the arrangement relationship between the candidate locations where the synchronization signal block can be transmitted and the candidate locations where the synchronization signal block cannot be transmitted in the set of candidate locations. Since the candidate positions where the synchronization signal block can be transmitted have a quasi co-location relationship, the synchronization signal block may be transmitted in a candidate position. In a sub-implementation of this embodiment, the specific method for determining the resource occupation position may be based on a set of candidate positions. Arrangement relationship, determining the candidate positions between the reference position and the group boundary and the nearest L candidate positions after the group boundary, which have a quasi co-location relationship with the candidate positions of the transmittable synchronization signal block The candidate position is used as the resource occupation position.

For the specific determination of the candidate location that has a quasi co-location relationship with the transmittable candidate location, reference may be made to the corresponding part in the foregoing embodiment, and details are not repeated here.

For example, as shown in Figure 10, the time when the indication information is received is the reference position, and the bitmap is used as the position configuration information. The bitmap is 11011101, that is, the effective length of the position configuration information is 8, which means that there are 8 candidate positions in a group. Candidate position. The quasi-co-location parameter used to determine the quasi-co-location relationship between candidate positions is Q=8, and the terminal device determines the number in the (3+8) candidate positions (that is, 5 to 15 in Figure 10) after the indication information After modulo Q, it is equal to 0 (corresponding to the first 1 in the bitmap), 1 (corresponding to the second 1 in the bitmap), 3 (corresponding to the fourth 1 in the bitmap), 4 (corresponding to the fifth in the bitmap The candidate positions of 1), 5 (corresponding to the sixth 1 in the bitmap), or 7 (corresponding to the eighth 1) are the resource occupied positions, as the PDCCH or PDSCH or other RS (such as CSI-RS, DMRS) cannot be transmitted ,TRS,PTRS) resources.

In another sub-implementation, the location configuration information may include an arrangement relationship between candidate locations where a synchronization signal block can be transmitted and candidate locations where a synchronization signal block cannot be transmitted in a set of candidate locations. According to the location configuration information, when one or more candidate locations are determined to be resource-occupied locations from the candidate locations between the reference location and the group boundary and the nearest L candidate locations after the group boundary, all candidate locations may be Among the L1 candidate positions between the reference position and the group boundary, the candidate position corresponding to the transmittable candidate position among the last L1 candidate positions in the arrangement relationship is used as the resource occupation position; and, Among the L nearest candidate positions after the group boundary, the candidate positions corresponding to the transmittable candidate positions in the arrangement relationship are used as the resource-occupied positions. It is understandable that the transmittable candidate position is a candidate position where the base station can transmit a synchronization signal block, that is, a candidate position where the base station may transmit a synchronization signal block. Among them, L1 represents the number of candidate positions from the reference position to the group boundary.

For example, as shown in FIG. 11, the position configuration information is 11011101, the length is 8, and the L1=3 candidate positions that indicate the information to the nearest group boundary thereafter are the candidate positions numbered 5-7 in the first part of FIG. 11. The resource occupied position is determined according to the last L1=3 bits of the position configuration information, that is, the candidate position corresponding to the transmittable candidate position among the last L1 candidate positions in the position configuration information. As shown in Figure 11, among the candidate positions numbered 5-7, number 5 corresponds to 1 in the 6th position in the position configuration information, number 6 corresponds to 0 in the 7th position in the position configuration information, and number 7 corresponds to the position configuration information 1 in the eighth position in the middle, it can be determined that among the 3 candidate positions between the indication information and the group boundary, the

numbers

5 and 7 are respectively the resource occupied positions.

In addition, in the second part of FIG. 11, candidate positions corresponding to numbers 8 to 15 are L=8 candidate positions after the nearest group boundary. Among the 8 candidate positions, the candidate positions corresponding to 1 in the position configuration information 11011101 are the candidate positions corresponding to

numbers

8, 9, 11, 12, 13, and 15, respectively, and the

numbers

8, 9, 11, and 15 can be determined. The candidate positions corresponding to 12, 13, and 15 are resource-occupied positions.

The embodiments of the present application also provide a second implementation manner. In this embodiment, the location configuration information may include the number L of a set of candidate locations used by the base station to transmit the synchronization signal block, where L is a positive integer. According to the position configuration information, determining the resource occupation position from the candidate positions after the reference position may be: determining the resource occupation position from the last L candidate positions after the reference position. For example, as shown in Figure 12, the position configuration information is a bitmap with an effective length of 8, and the indication information is used as a reference position. Between the candidate position numbered 4 and the candidate position numbered 5 in Figure 12, you can start from 8 after the indication information. The resource-occupied location is determined from the candidate locations, that is, the resource-occupied location is determined from the candidate locations numbered 5 to 12.

Optionally, in this implementation manner, all the L nearest candidate positions after the reference position may be determined as resource-occupied positions.

Optionally, in this implementation manner, among the nearest L candidate positions after the reference position, candidate positions that may transmit synchronization signal blocks may be used as resource occupation positions.

The location configuration information may include the arrangement relationship between the candidate locations where the synchronization signal block can be transmitted and the candidate locations where the synchronization signal block cannot be transmitted in the set of candidate locations. Since the candidate positions where the synchronization signal block can be transmitted have a quasi co-location relationship, the synchronization signal block may be transmitted in a candidate position. In a sub-implementation of this embodiment, according to the position configuration information, from the nearest L candidates after the reference position The resource occupancy position is determined in the position, which may be, according to the arrangement relationship, the nearest L candidate positions after the reference position are determined, which have a quasi co-location relationship with the candidate positions that can transmit the synchronization signal block in the arrangement relationship The candidate position is used as the resource occupation position.

For example, as shown in Figure 12, the time when the instruction information is received is the reference position, and the bitmap is used as the location configuration information. The bitmap is 11011101, that is, the effective length of the location configuration information is 8, which means that there are 8 candidate positions in a group. Candidate position. The quasi co-location parameter used to determine the quasi co-location relationship between candidate positions is Q=8, and the terminal device determines the resource-occupied position among the eight candidate positions after the indication information. As shown in Figure 12, because in the candidate position, the number and Q are modulo 0 (corresponding to the first 1 in the bitmap), 1 (corresponding to the second 1 in the bitmap), and 3 (corresponding to the first 1 in the bitmap). Four 1), 4 (corresponding to the fifth 1 in the bitmap), 5 (corresponding to the sixth 1 in the bitmap), or 7 (corresponding to the eighth 1) candidate positions corresponding to 1 in the bitmap, then determine Among the 8 candidate positions after the indication information, the candidate positions numbered 5, 7, 8, 9, 11, and 12 are resource occupied positions.

In another sub-implementation, all candidate positions in the transmission window are grouped into a group for every adjacent L, and finally multiple candidate positions that do not satisfy the number L are grouped into a group. The location configuration information may include an arrangement relationship between candidate locations where a synchronization signal block can be transmitted and candidate locations where a synchronization signal block cannot be transmitted in a set of candidate locations.

In this sub-implementation, determining the resource occupation position from the nearest L candidate positions after the reference position according to the position configuration information may include: determining the nearest group boundary after the reference position; and determining the reference position to the Among the L2 candidate positions between the nearest group boundaries, the candidate position corresponding to the last L2 transmittable candidate positions in the arrangement relationship is used as the resource occupation position; and, after determining the nearest group boundary Among the L3 candidate positions, the candidate position corresponding to the transmittable candidate position among the first L3 candidate positions in the arrangement relationship is used as the resource occupation position, L2 and L3 are non-negative integers, and the sum of L2 and L3 Is L. It can be understood that L2 represents the number of candidate positions between the reference position and the group boundary. The transmittable candidate position is a candidate position where the base station can transmit a synchronization signal block, that is, a candidate position where the base station may transmit a synchronization signal block.

For example, as shown in Figure 13, the time when the indication information is received is the reference position, and the bitmap is used as the location configuration information. The bitmap is 11011101, that is, the effective length of the location configuration information is 8, which means that there are 8 candidate positions in a group. Candidate position. The L2=3 candidate positions between the indication information and the nearest neighbor group boundary are the first part in FIG. 13, and the candidate positions numbered 5-7. The resource occupation position is determined according to the last L2=3 bits of the position configuration information, that is, the candidate position corresponding to the transmittable candidate position among the last L2 candidate positions in the position configuration information. As shown in Figure 13, among the candidate positions numbered 5-7, number 5 corresponds to 1 in the 6th position in the position configuration information, number 6 corresponds to 0 in the 7th position in the position configuration information, and number 7 corresponds to the position configuration information 1 in the eighth position in the middle, it can be determined that among the 3 candidate positions between the indication information and the group boundary, the

numbers

5 and 7 are respectively the resource occupied positions.

In addition, in FIG. 13, candidate positions numbered 8 to 12 are L3=5 candidate positions behind the nearest group boundary. Among the candidate positions numbered 8 to 12, the number 8 corresponds to the 1 in the first position in the position configuration information, the number 9 corresponds to the 1 in the second position in the position configuration information, and the number 10 corresponds to the third in the position configuration information. Position 0 and number 11 correspond to 1 in the 4th position in the position configuration information, and number 12 corresponds to 1 in the 5th position in the position configuration information. Then the 5 candidate positions after the nearest group boundary can be numbered 8, 9 , 11, and 12 are resource occupation positions respectively.

In the first implementation manner described above, if the reference position is at the group boundary, the resource occupation position may be determined from the nearest L candidate positions after the reference position.

In the embodiments of the present application, the above two implementation manners can be implemented alternatively. Or, when the reference position is at the group boundary, the resource occupation position is determined in the second embodiment described above, that is, the resource occupation position is determined from the nearest L candidate positions after the reference position; if the reference position is not at the group boundary, Then the resource occupation position can be determined in the above-mentioned first implementation manner, that is, one or more candidate positions can be determined from the candidate positions between the reference position and the group boundary and the nearest L candidate positions after the group boundary. The location is the resource occupied location.

Therefore, optionally, in this embodiment of the present application, it can also be determined whether the reference position is at the group boundary. If yes, execute the second implementation manner, that is, determine the resource-occupied location from the latest L candidate locations after the reference location; if not, execute the second implementation manner, that is, from the reference location and the location Among the candidate positions between the group boundaries and the nearest L candidate positions after the group boundary, one or more candidate positions are determined as resource-occupied positions.

That is to say, in the case that the indication information is not received, the above-mentioned determination of the resource occupation position according to the above-mentioned second embodiment or the third embodiment may be performed.

In the transmission window, when the instruction information sent by the base station is received, in the transmission window, when the instruction information sent by the base station is received, the reference position can be determined according to the instruction information, and the position configuration Information, the resource occupation position is determined from the candidate position after the reference position. That is, when the instruction information is received, the resource occupation position is determined according to the embodiment corresponding to the above step S410 to step S430.

In another embodiment, the method according to which the resource occupation position is determined can be determined according to the instruction of the base station. Specifically, the configuration information sent by the base station can be obtained, and the manner of resource occupation can be determined according to the configuration information.

If it is determined that the resource occupation position is to be determined, the resource occupation position among all candidate positions in the synchronization signal block transmission window can be determined according to the position configuration information, that is, the resource occupation position method in the foregoing embodiment can be performed.

In the embodiments of the present application, the configuration information involved in different embodiments may be the same or different. If the same, the information used in the configuration information may be different in different embodiments.

In the embodiment of the present application, the second information in the configuration information may be used to determine whether to determine the resource occupation location. If the second information indicates that the resource occupancy position is to be determined, then it is determined to determine the resource occupancy position; if the second information indicates that the resource occupancy position is uncertain, the resource occupancy position may be uncertain.

This application also provides an embodiment, which is applied to the base station side. Specifically, please refer to Figure 14. This embodiment includes:

Step S510: Send location configuration information to the terminal device.

Step S520: In the transmission window, when listening first and then speaking success (LBT success), starting from the nearest candidate position, send the corresponding and unsuccessful synchronization signal block to the terminal device.

In the candidate positions corresponding to the synchronization signal block, each candidate position transmits the synchronization signal block in a different direction of wave speed. Therefore, the same synchronization signal block can only be sent at its corresponding candidate position, and the corresponding synchronization signal block The candidate locations have quasi co-location parameters.

Therefore, when the base station LBT succeeds, indicating that the synchronization signal block can be sent, the synchronization signal block starts to be sent from the nearest candidate position where the synchronization signal block needs to be sent.
