Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In the 5G technology, since the successful location of the base station LBT (Listen Before Talk) on the unlicensed spectrum is unpredictable, if the LBT fails, it is likely to cause the transmission failure of the SSB by the base station, and also likely to cause the reception failure of the SSB by the terminal device. In the NR-U, one SSB is transmitted at a candidate location, and one candidate location may be used for transmitting one SSB or may not be used for transmitting the SSB, so that a plurality of candidate locations transmitted by the SSB may be provided, and the number of the provided candidate locations is greater than the number of SSBs to be transmitted at most, so that after LBT succeeds, sufficient candidate locations may still be used for the base station to transmit the SSB, and accordingly, the influence of LBT failure on the reception of the SSB by the terminal device is avoided, as shown in fig. 1. For example, if the base station sends 8 SSBs at most in one transmission period, more than 8 candidate locations may be configured, for example, 20 candidate locations for SSB transmission are preconfigured, and 8 SSBs can be transmitted at most in the 20 candidate locations for SSB transmission. As shown in fig. 1, the candidate position is a position in the time domain.

Since some candidate locations may have SSB transmission and some candidate locations may not have SSB transmission, if all candidate locations are used as candidate locations for SSB transmission, the terminal device may not perform rate matching well and may waste available resources, so that the terminal device may determine which candidate locations do not have SSB transmission and which candidate locations may have SSB transmission, so as to facilitate the UE to perform rate matching on the candidate locations for which SSB transmission is possible, and to utilize the candidate locations without SSB transmission for transmitting other information, such as Physical Downlink Control CHannel (PDCCH), Physical Downlink Shared CHannel (PDSCH), or other Reference Signals (RS, Reference Signals), such as CHannel state information Reference Signals (CSI-RS, Channel-State Information Reference Signal), DeModulation Reference Signal (DMRS), Tracking Reference Signal (TRS), phase noise tracking Reference Signal (PTRS), and the like.

Therefore, the inventor proposes a method for determining a resource occupation location in an embodiment of the present application, which is used for a terminal device to determine candidate locations that may perform SSB transmission in an unlicensed frequency band, and correspondingly, may determine locations that do not perform SSB transmission in all the candidate locations at the same time.

First embodiment

Fig. 2 shows a method for determining a resource occupation location according to a first embodiment of the present application. The method can be applied to terminal equipment. Specifically, the method comprises the following steps:

step S110: and acquiring position configuration information, wherein the position configuration information comprises the configuration situation of the candidate position of the transmission synchronization signal block by the base station.

The base station may transmit location configuration information, which may be indication information (index), to the terminal device, so as to inform the terminal device of the base station's configuration of the candidate locations for transmitting the synchronization signal block. The terminal device may obtain the location configuration information, so as to determine the transmission condition of the synchronization signal block at each candidate location, that is, determine which candidate location base stations may send the synchronization signal block to the terminal device, and determine which candidate location base stations may not send the synchronization signal block to the terminal device. The terminal device may receive the synchronization signal block at a candidate position where the base station may transmit the synchronization signal block, and the terminal device may not receive the synchronization signal block at a candidate position where the base station may not transmit the synchronization signal block.

Step S120: and determining resource occupation positions in all candidate positions in a synchronous signal block transmission window according to the position configuration information, wherein the candidate positions are positions for transmitting the synchronous signal block.

According to the position configuration information, the candidate positions which are possible to send the synchronous signal block in all the candidate positions in each transmission window of the synchronous signal block can be determined, and the candidate positions which are possible to send the synchronous signal block are taken as the resource occupation positions. It is understood that the candidate position is a position for transmitting the synchronization signal block, and for the base station, a position for transmitting the synchronization signal block, and for the terminal device, a position for receiving the synchronization signal block.

In the embodiment of the present application, a candidate position at which a synchronization signal block may be transmitted in a transmission window may be determined as a determined resource occupation position according to position configuration information that reflects a candidate position configuration situation and is sent by a base station.

Second embodiment

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

step S210: receiving location configuration information, the location configuration information comprising: the base station is used for transmitting the arrangement relation between the candidate position of the synchronous signal block and the candidate position of the synchronous signal block which can not be transmitted in a group of candidate positions of the synchronous signal block.

In the location configuration information, a group of candidate locations for transmitting the synchronization signal block may be included, and an arrangement relationship between the candidate locations for transmitting the synchronization signal block and the candidate locations for not transmitting the synchronization signal block may be included. The candidate position where the synchronization signal block can be transmitted is a candidate position where the synchronization signal block can be transmitted, and the candidate position where the synchronization signal block cannot be transmitted is a candidate position where the synchronization signal block cannot be transmitted. Each candidate position in the set of candidate positions is adjacent in the time domain. The candidate position where the synchronization signal block may be sent indicates that, in a transmission period, if the LBT is successful and the synchronization signal block corresponding to the candidate position is not transmitted, the base station transmits the corresponding synchronization signal block at the candidate position.

The base station may use a bitmap (bitmap) as the location configuration information, and send the configuration status of a group of candidate locations in the form of the bitmap, where each bit (bit) in the bitmap represents one candidate location, and the effective bit number in the bitmap is the number of candidate locations in the group of candidate locations, or the length of the bitmap is the number of candidate locations in the group of candidate locations. Also, in the bitmap, a candidate position where a synchronization signal block may be transmitted may be represented by one of 0 or 1, and the other represents a candidate position where a synchronization signal block may not be transmitted. The arrangement of 0 and 1 represents the arrangement relationship between the candidate positions where the synchronization signal block can be transmitted and the candidate positions where the synchronization signal block cannot be transmitted among the set of candidate positions. For example, a candidate position where a synchronization signal block is actually likely to be transmitted is represented by 1 in the bitmap, and 0 represents a candidate position where a synchronization signal block is not likely to be transmitted, the arrangement relationship between the candidate position of a transmittable synchronization signal block and the candidate position of an untransmittable synchronization signal block can be determined according to the arrangement of 1 and 0.

For example, the bitmap indicating the configuration of a group of candidate locations in the configuration information is 1101, which indicates that, in a group of candidate locations, the first, second, and fourth candidate locations may have corresponding SSBs to transmit, and there is no corresponding SSB to transmit in the third candidate location.

Optionally, in this embodiment of the present application, valid configuration information in the location configuration information may also be determined. After the valid configuration information is determined, when the resource occupation positions in all the candidate positions in the synchronization signal block transmission window are determined according to the position configuration information, the resource occupation positions in all the candidate positions in the synchronization signal block transmission window can be determined according to the valid configuration information. 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 to be relied on is the determined valid configuration information.

In the embodiment of the present application, in the received location configuration information, if the number of a group of candidate locations is greater than the value Q of the quasi-co-location parameter, the first Q candidate locations in the location configuration information may be used as effective location configuration information; or, the last Q candidate positions in the position configuration information are taken as effective position configuration information; or just to use the location configuration information as valid configuration information. The quasi co-location parameter is used for determining a quasi co-location relation between candidate positions in a transmission window, and the quasi co-location parameter Q is a positive integer.

For example, the position 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 effective configuration information; or taking the first Q bit of the bitmap as effective configuration information; or taking the last Q bit of the bitmap as effective configuration information.

Step S220: and circularly expanding the arrangement relation to all candidate positions in the transmission window.

Step S230: and determining candidate positions of one or more transmittable synchronous signal blocks in all the expanded candidate positions as the resource occupation positions.

In the embodiment of the present application, a transmittable candidate position in all candidate positions in the transmission window may be determined according to the extension of the arrangement relationship in a group of candidate positions, where the transmittable candidate position is a candidate position where the synchronization signal block may be transmitted.

Specifically, K represents the number of all candidate positions in the transmission window, and if K is a positive integer, the cyclic extension is to cyclically extend the arrangement relationship of a group of candidate positions in the position configuration information among the K candidate positions, so as to realize that each candidate position in the K candidate positions corresponds to a candidate position where a synchronization signal block may be transmitted or a position where a synchronization signal block may not be transmitted, and thus one or more transferable candidate positions in the K candidate positions after extension can be determined as the resource occupation position.

For example, the position configuration information is represented by a bitmap, 1 corresponds to a candidate position where a synchronization signal block may be transmitted, 0 corresponds to a candidate position where a synchronization signal block may not be transmitted, the effective length of the bitmap is L bits, and when there are K candidate positions in the transmission window, the position configuration information of L bits is extended to the K candidate positions. Or, the L bit is expanded into the K bit, and the candidate position corresponding to the expanded 1 is determined as the resource occupation position.

As shown in fig. 4, assuming that the location configuration information is 11010101 and there are 20 candidate locations within the transmission window of the synchronization signal block, the location configuration information is cyclically extended to 20 candidate locations, which is 11010101110101011101. Where 1 corresponds to a candidate location where a sync signal block may be transmitted and 0 corresponds to a candidate location where a sync signal block may not be transmitted. Then, in the extended 20 candidate locations, it may be determined that the candidate location corresponding to 1 is the resource occupation location, and the candidate location corresponding to 0 is the non-resource occupation location, and there is no SSB transmission, which may be used for transmitting other information.

In the embodiment of the present application, the arrangement relationship of the candidate positions in the position 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.

Third embodiment

When two reference signals (e.g., synchronization signal blocks) have a quasi co-located (QCL) relationship, the large-scale parameters (e.g., doppler delay, average delay, spatial reception parameters, etc.) of the two reference signals can be considered to be mutually inferred, or can be considered to be similar. Correspondingly, the candidate positions with the quasi-co-location relation can transmit the same synchronization signal block, so the application also provides an embodiment for determining the candidate position corresponding to the transmittable candidate position in all the candidate positions of the synchronization signal transmission window according to the arrangement relation of a group of candidate positions, and the candidate position is the resource occupation position. Specifically, in this embodiment, the resource occupation position may be determined according to the quasi co-location relationship. As shown in fig. 5, the method provided in the embodiment of the present application includes:

step S310: acquiring position configuration information, wherein the position configuration information comprises: the base station is used for transmitting the arrangement relation between the candidate position of the synchronous signal block and the candidate position of the synchronous signal block which can not be transmitted in a group of candidate positions of the synchronous signal block.

The configuration of the candidate positions for transmitting the synchronization signal block by the base station may include the arrangement relationship of the candidate positions, so that the arrangement relationship may be obtained according to the position configuration information. For the detailed description of this step, reference may be made to the foregoing embodiments, which are not described herein again.

Step S320: and according to the arrangement relation, determining a candidate position which has a quasi-co-location relation with a transmittable candidate position in all candidate positions of the synchronous signal transmission window as the resource occupation position, wherein the transmittable candidate position is the position of a transmittable synchronous signal block.

Among all candidate positions in one transmission window, there may be candidate positions having a quasi-co-location relationship. Thus, candidate positions having a quasi-co-location relationship therein can be determined.

The quasi co-location relationship can be determined according to a quasi co-location parameter, the quasi co-location parameter can be a positive integer, and the embodiment of the application is represented by Q. The terminal device may obtain the quasi co-location parameter from the base station.

In addition, all candidate positions in the transmission window may correspond to a number, which the terminal device may obtain from a base station or a protocol predefined manner.

If the numbers of the two candidate positions are the same as the value obtained by taking the modulus of Q, the two candidate positions can be determined to have the quasi-co-location relation. For example, the numbers of two candidate positions are M1 and M2, respectively, and 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 fig. 6, if Q has a value of 8, and the numbers modulo Q corresponding to SSBs with candidate positions of 0, 8, and 16 are all 0, it can be determined that the candidate positions with candidate positions of 0, 8, and 16 have a quasi-co-location relationship.

In the embodiment of the present application, the candidate position having a quasi-co-location relationship with the transmittable candidate position may be determined as a candidate position having a quasi-co-location relationship with the transmittable candidate position if a value obtained by modulo alignment of a number of the candidate position with a co-location parameter corresponds to a position of the transmittable candidate position in a group of candidate positions.

Specifically, when determining a candidate position having a quasi-co-location relationship with a transmittable candidate position among all candidate positions in the synchronization signal transmission window, the numbers of all candidate positions in the transmission window may be obtained. And calculating the values after aligning the common address parameters in all the numbers and obtaining a plurality of module values. And determining a module value corresponding to the arrangement position of the candidate position capable of being transmitted in the arrangement relation in the plurality of module values, and taking the candidate position corresponding to the determined module value as a candidate position having a quasi-co-location relation with the candidate position capable of being transmitted. The transmittable candidate positions are candidate positions at which the synchronization signal block can be transmitted, that is, candidate positions at which the synchronization signal block can be transmitted.

The correspondence between the module value and the arrangement position may be understood as that, in all K candidate positions in the transmission window, including the 1 st to the K th candidate positions, the module value obtained by the number of the first candidate position corresponds to the first candidate position in the arrangement relationship; and the module value obtained by the serial number of the second candidate position corresponds to the second candidate position in the arrangement relation, and the like is repeated until the module value obtained by the serial number of the L-th candidate position corresponds to the L-th candidate position in the arrangement relation. Wherein the arrangement relationship comprises a group of L candidate positions.

For example, as shown in fig. 7, it is assumed that the location configuration information is 1101 and the quasi-co-location parameter is 4. The candidate position with the number modulo 4 and equal to 0 corresponds to the first 1 in the position configuration information; the candidate position with the number modulo 4 and equal to 1 corresponds to the second 1 in the position configuration information; the candidate position with the number modulo 4 equal to 3 corresponds to the fourth 1 in the location configuration information, and the terminal device may determine that the candidate position with the number modulo 4 equal to 0 (e.g., the

number

0, 4, 8, 12, 16 in fig. 7), the number modulo 4 equal to 1 (e.g., the

number

1, 5, 9, 13, 17 in fig. 7), and the number modulo 4 equal to 3 (e.g., the

number

3, 7, 11, 15, 19 in fig. 7) is the resource occupation location.

Optionally, in the transmission window, for the xth candidate position, X is taken as a ranking position of the candidate position in the transmission window in the time domain. The number corresponding to the xth candidate position may be the last three digits of X, for example, X is 9 (decimal), that is, 1001, and then the number corresponding to the candidate position is 001, that is, 1 in decimal. In addition, optionally, the number corresponding to the X-th candidate position may also be X, for example, X is 9, and then the corresponding number is 9. Alternatively, as shown in FIG. 7, the candidate positions in the transmission window may start from 0, 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 a number for illustration. Of course, if the number of the candidate position is in another form, for example, the last three bits of the ranking position X, the ranking position is the candidate position of X, and when taking the modulus for Q, the Q is taken modulo by the last three bits. If the last three bits of 9 are used as the number, as for the 9 th candidate position in fig. 7 (i.e., the candidate position corresponding to the number 9 in fig. 7), since the binary number of 9 is 0001, the last three bits 001 modulo Q.

In the embodiment of the application, the candidate position having the quasi-co-location relation with the transmittable candidate position can be determined as the resource occupation position according to the quasi-co-location parameter, so that the determination speed of the resource occupation position is improved.

Fourth embodiment

Because the base station has a higher possibility of sending the synchronization signal block under the condition of preempting the channel, the application also provides an embodiment, and the resource occupation position can be determined from the candidate position in the transmission window when the base station is determined to preempt the channel, so that the determined resource occupation position is more accurate. Specifically, referring to fig. 8, the method of this embodiment includes:

step S410: and acquiring position configuration information, wherein the position configuration information comprises the configuration situation of the candidate position of the transmission synchronization signal block by the base station.

Step S420: and in the transmission window, when receiving indication information sent by a base station, determining a reference position according to the indication information, wherein the indication information indicates that the base station has preempted a channel.

The indication information is information that may indicate that the base station has preempted the channel, and may be, for example, COT indication, DCI message (carried on PDCCH or GC-PDCCH), or other reference information (e.g., SSB, CSI-RS, TRS, DMRS), or the like. Optionally, in this embodiment, any information sent from the base station may be used as the indication information.

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

In one implementation, in the embodiment of the present application, the time when the indication information is received may be directly used as the reference position.

In another embodiment, the location where the sync signal block is transmitted may be set with some preset conditions, such as transmitting in even bits, transmitting in multiples of 4, and transmitting in multiples of 8. Therefore, in the embodiment of the present application, a candidate position that is closest to a time when the indication information is received and satisfies a preset condition may be obtained as the reference position.

In the transmission window, all candidate positions can be grouped, starting from the first candidate position, after every adjacent L groups of candidate positions in the transmission window, the last candidate positions which are less than L are grouped into a group, and the boundary between the two groups is defined as the group boundary. Where L is the number of a set of candidate locations indicated in the location configuration information. Optionally, in this embodiment of the present application, the candidate position meeting the preset condition may be a first candidate position after the group boundary.

In addition, optionally, in the embodiment of the present application, the candidate position meeting the preset condition may also be a candidate position numbered as an even number; or candidate locations numbered as multiples of 4; or candidate positions numbered as multiples of 8; or a candidate position closest to the indication information, etc., may be set as needed.

Wherein the candidate positions are numbered as even numbers; or candidate locations numbered as multiples of 4; or candidate positions numbered as multiples of 8, etc. may be calculated according to a formula, where X mod G is 0, and represents the transmission window, as described above, the xth candidate position represents the candidate position numbered as X, and the value of G may be set according to a preset condition, for example, if the candidate position satisfying the preset condition is the candidate position numbered as an even number, the value of G is 2; if the candidate position meeting the preset condition is a candidate position with the number being a multiple of 4, the value of G is 4; if the candidate position meeting the preset condition is a candidate position with the number being a multiple of 8, the value of G is 8; and if the candidate position meeting the preset condition is the nearest candidate position after the indication information, the value of G is 1. Wherein G can be determined in one of the following ways: broadcast messages, including MIB, SIB1(RMSI), SIB; RRC-specific signaling; the protocol is agreed in advance.

Step S430: and determining the resource occupation position from the candidate position after the reference position according to the position configuration information.

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

In this embodiment, 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, and may be specifically set according to the requirement.

In the embodiment of the application, the time when the indication information is received is mainly taken as a reference position for example, and the description of determining the resource occupation position is performed.

In the embodiment of the present application, determining the resource occupation position from the candidate position after the reference position may be that all candidate positions after the reference position are used as the resource occupation position; or, taking the candidate positions of all possible transmission synchronization signal blocks after the reference position as resource occupation positions; alternatively, the resource occupation location is determined from a specified number of candidate locations after the reference location, which specified number may be determined based on the reference location and the number of a set of candidate locations.

The following describes, in various embodiments, a number of candidate positions after the reference position is specified, and the resource occupation position is determined.

In the first embodiment, the location configuration information may include the number L of a set of candidate locations for transmitting the synchronization signal block by the base station, where L is a positive integer. Every adjacent L candidate positions in all the candidate positions of the synchronization signal block in the transmission window can be divided into a group, and finally the candidate positions which do not meet the quantity L are divided into a group. The boundary between two packets is taken as the group boundary.

In this embodiment, when determining the resource occupying position from the candidate position after the reference position according to the position configuration information, a group boundary closest to the reference position may be determined, and one or more candidate positions may be determined as the resource occupying position from among the candidate positions between the reference position and the group boundary and the L closest candidate positions after the group boundary.

In this embodiment, a packet will be described by taking a bitmap as position arrangement information as an example. The effective length of the bitmap is L, and if the value of L is 8, each packet of L candidate positions in the transmission window may be as shown in fig. 9, and since the last 4 candidate positions (i.e. candidate positions numbered 16 to 19 in fig. 9) do not satisfy 8, the 4 candidate positions are grouped into one group. In the grouping shown in fig. 9, there is a group boundary between 7 and 8 and a group boundary between 16 and 16. Optionally, in this embodiment of the present application, before the first candidate position and after the last candidate position in the transmission window may also be used as the group boundary, as shown in fig. 8 before the candidate position numbered 0 and after the candidate position numbered 19. The first number information in fig. 9 is the number of the candidate position.

After determining the reference position, the group boundary closest to the reference position may be determined, i.e. after the time instant of the reference position and closest to the time instant of the reference position. As shown in fig. 10, the time corresponding to the indication information is the reference position, and the closest group boundary of the reference position is between 7 and 8 in conjunction with fig. 9.

In this embodiment, one or more candidate positions may be determined as the resource occupying positions from the candidate positions between the reference position and the nearest group boundary, and the 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 L candidate positions after the nearest group boundary may be used as the resource occupation positions. For example, as shown in fig. 10, when the candidate positions numbered 5 to 7 are candidate positions between the reference position and the nearest group boundary, and the candidate positions numbered 8 to 15 are L candidate positions after the nearest group boundary, the candidate positions numbered 5 to 7 and 8 to 15 are determined as the resource occupying positions.

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

The position configuration information may include an arrangement relationship between candidate positions of the group of candidate positions at which the synchronization signal block may be transmitted and candidate positions at which the synchronization signal block may not be transmitted. Since the candidate positions where the candidate positions of the transmittable synchronization signal block have a quasi-co-location relationship may transmit the synchronization signal block, in a sub-implementation of this implementation, the resource occupying position may be specifically determined by determining, as the resource occupying position, a candidate position having a quasi-co-location relationship with the candidate position of the transmittable synchronization signal block, from among the candidate position between the reference position and the group boundary and the latest L candidate positions after the group boundary, according to the arrangement relationship of a group of candidate positions.

For the determination of the candidate position having the quasi-co-location relationship with the transmittable candidate position, reference may be made to the corresponding parts in the foregoing embodiments, and details are not described herein again.

For example, as shown in fig. 10, the time when the instruction information is received is used as a reference position, a bitmap is used as the position arrangement information, the bitmap is 11011101, that is, the effective length of the position arrangement information is 8, and it indicates that there are 8 candidate positions in a group of candidate positions. If the quasi-co-location parameter used for determining the quasi-co-location relationship between the candidate locations is Q8, the terminal device determines, among (3+8) candidate locations (i.e., 5 to 15 in fig. 10) after the indication information, that the candidate location whose number and Q are modulo 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 1 in the bitmap), 5 (corresponding to the sixth 1 in the bitmap), or 7 (corresponding to the eighth 1) is a resource occupation location, as a resource where the PDCCH or the PDSCH or other RSs (e.g., CSI-RS, DMRS, TRS, PTRS) may not be transmitted.

In another sub-embodiment, the position configuration information may include an arrangement relationship between candidate positions of a group of candidate positions where a synchronization signal block may be transmitted and candidate positions where a synchronization signal block may not be transmitted. When one or more candidate positions are determined to be resource occupation positions from the candidate positions between the reference position and the group boundary and the nearest L candidate positions after the group boundary according to the position configuration information, the candidate position corresponding to a transferable candidate position from among the L1 candidate positions between the reference position and the group boundary and the last L1 candidate positions in the arrangement relationship may be used as the resource occupation position; and taking the candidate position corresponding to the transferable candidate position in the arrangement relation in the L nearest candidate positions after the group boundary as the resource occupation position. It is understood that the transmittable candidate positions are candidate positions where the base station can transmit the synchronization signal block, i.e., candidate positions where the base station can transmit the synchronization signal block. Where L1 denotes the number of candidate positions between the reference position to the group boundary.

For example, as shown in fig. 11, the location configuration information is 11011101, the length is 8, and L1, which indicates that the information is closest to the group boundary after the location configuration information, is 3 candidate locations, which are numbered 5 to 7 in the first part of fig. 11. And determining the resource occupation position according to the last L1 ═ 3 bits of the position configuration information, namely the candidate position corresponding to the transmittable candidate position in the last L1 candidate positions in the position configuration information. As shown in fig. 11, of the candidate locations numbered 5-7, the candidate location numbered 5 corresponds to 1 of the 6 th location in the location configuration information, the candidate location numbered 6 corresponds to 0 of the 7 th location in the location configuration information, and the candidate location numbered 7 corresponds to 1 of the 8 th location in the location configuration information, so that of the 3 candidate locations between the indication information and the group boundary, the candidate locations numbered 5 and 7 are the resource occupation locations, respectively.

In the second part of fig. 11, the candidate positions corresponding to numbers 8 to 15 are 8 candidate positions after the nearest group boundary. Of the 8 candidate positions, the candidate positions sequentially corresponding to 1 in the positional arrangement information 11011101 are the candidate positions corresponding to the

numbers

8,9,11, 12, 13, and 15, respectively, and then the candidate positions corresponding to the

numbers

8,9,11, 12, 13, and 15 can be specified as the resource occupying positions.

The embodiment of the application also provides a second implementation mode. In this embodiment, the location configuration information may include the number L of a set of candidate locations for the base station to transmit the synchronization signal block, where L is a positive integer. According to the location configuration information, determining a resource occupation location from the candidate location after the reference location may be: and determining the resource occupation position from the latest L candidate positions after the reference position. For example, as shown in fig. 12, the location configuration information is a bitmap with an effective length of 8, the indication information is used as a reference location, and between the candidate location with the number 4 and the candidate location with the number 5 in fig. 12, the resource occupation location can be determined from the 8 candidate locations after the indication information, that is, the resource occupation location can be determined from the candidate locations with the numbers 5 to 12.

Optionally, in this embodiment, all the latest L candidate positions after the reference position may be determined as the resource occupation positions.

Optionally, in this embodiment, the candidate position, which may transmit the synchronization signal block, in the latest L candidate positions after the reference position may be used as the resource occupation position.

The position configuration information may include an arrangement relationship between candidate positions of the group of candidate positions at which the synchronization signal block may be transmitted and candidate positions at which the synchronization signal block may not be transmitted. Since the candidate positions at which the candidate positions of the transmittable synchronization signal block have a quasi-co-location relationship may transmit the synchronization signal block, in a sub-embodiment of this embodiment, the resource occupation position is determined from the latest L candidate positions after the reference position according to the position configuration information, and a candidate position having a quasi-co-location relationship with the candidate position at which the synchronization signal block is transmittable in the arrangement relationship, from among the latest L candidate positions after the reference position is determined according to the arrangement relationship, may be the resource occupation position.

For example, as shown in fig. 12, the time when the instruction information is received is used as a reference position, a bitmap is used as the position arrangement information, the bitmap is 11011101, that is, the effective length of the position arrangement information is 8, and it indicates that there are 8 candidate positions in a group of candidate positions. And if the quasi co-location parameter used for determining the quasi co-location relationship between the candidate positions is Q-8, the terminal device determines the resource occupation position in the 8 candidate positions after the indication information. As shown in fig. 12, since the candidate positions with numbers 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 1 in the bitmap), 5 (corresponding to the sixth 1 in the bitmap), or 7 (corresponding to the eighth 1) modulo the Q in the candidate positions correspond to 1 in the bitmap, the candidate positions with numbers of 5,7,8,9,11, and 12 in the 8 candidate positions after the indication information is determined are the resource occupation positions.

In another sub-embodiment, every adjacent L candidate positions in the transmission window are grouped into one group, and finally, a plurality of candidate positions which do not satisfy the number L are grouped into one group. The location configuration information may include an arrangement relationship between candidate locations where the synchronization signal block may be transmitted and candidate locations where the synchronization signal block may not be transmitted among the set of candidate locations.

In this sub embodiment, determining the resource occupation location from the latest L candidate locations after the reference location according to the location configuration information may include: determining a nearest group boundary after the reference location; determining, as the resource occupying positions, candidate positions corresponding to the last L2 transmittable candidate positions in the arranging relationship, from among L2 candidate positions between the reference position and the nearest group boundary; and determining a candidate position corresponding to a transmittable candidate position among the first L3 candidate positions in the arrangement relation among the L3 candidate positions after the nearest group boundary as the resource occupation position, wherein L2 and L3 are non-negative integers, and a sum of L2 and L3 is L. It will be appreciated that L2 represents the number of candidate locations between the reference location and the group boundary. The transmittable candidate position is a candidate position where the base station can transmit the synchronization signal block, that is, a candidate position where the base station can transmit the synchronization signal block.

For example, as shown in fig. 13, the time when the instruction information is received is used as a reference position, a bitmap is used as the position arrangement information, the bitmap is 11011101, that is, the effective length of the position arrangement information is 8, and it indicates that there are 8 candidate positions in a group of candidate positions. The L2-3 candidate positions between the pointer information to the nearest group boundary are the first part of fig. 13, numbered 5-7 candidate positions. And determining the resource occupation position according to the last L2-3 bits of the position configuration information, namely the candidate position corresponding to the transmittable candidate position in the last L2 candidate positions in the position configuration information. As shown in fig. 13, of the candidate locations numbered 5-7, the candidate location numbered 5 corresponds to 1 of the 6 th location in the location configuration information, the candidate location numbered 6 corresponds to 0 of the 7 th location in the location configuration information, and the candidate location numbered 7 corresponds to 1 of the 8 th location in the location configuration information, so that of the 3 candidate locations between the indication information and the group boundary, the candidate locations numbered 5 and 7 are the resource occupation locations, respectively.

In fig. 13, the candidate positions of nos. 8 to 12 are L3, which are the nearest group boundaries, are 5 candidate positions. Among the candidate positions numbered 8 to 12, the candidate position numbered 8 corresponds to 1 at the 1 st position in the position configuration information, the candidate position numbered 9 corresponds to 1 at the 2 nd position in the position configuration information, the candidate position numbered 10 corresponds to 0 at the 3 rd position in the position configuration information, the candidate position numbered 11 corresponds to 1 at the 4 th position in the position configuration information, and the candidate position numbered 12 corresponds to 1 at the 5th position in the position configuration information, so that the candidate positions numbered 8,9,11, and 12 can be resource occupation positions respectively in the 5 candidate positions following the nearest group boundary.

In the first embodiment, if the reference location is on the group boundary, the resource occupation location may be determined from the nearest L candidate locations after the reference location.

In the embodiment of the present application, the above two implementation manners may be alternatively implemented. Or, when the reference position is at the group boundary, determining the resource occupation position in the second embodiment, that is, determining the resource occupation position from the nearest L candidate positions after the reference position; if the reference location is not at the group boundary, the resource occupation location may be determined in the first embodiment, that is, one or more candidate locations are determined as the resource occupation location from the candidate locations between the reference location and the group boundary and the L nearest candidate locations after the group boundary.

Therefore, optionally, in the embodiment of the present application, it may also be determined whether the reference position is at a group boundary. If yes, executing the second implementation mode, namely determining the resource occupation position from the latest L candidate positions after the reference position; if not, the second implementation manner is executed, that is, one or more candidate positions are determined as the resource occupation positions from the candidate positions between the reference position and the group boundary and the nearest L candidate positions after the group boundary.

That is, in the case where the indication information is not received, the above determination of the resource occupying position according to the second embodiment or the third embodiment may be performed.

In the transmission window, when receiving the indication information sent by the base station, the reference position may be determined according to the indication information, and according to the position configuration information, the resource occupation position may be determined from the candidate position after the reference position. That is, when the indication information is received, the resource occupation location is determined according to the embodiments corresponding to the above steps S410 to S430.

In another embodiment, the resource occupation location can be determined according to the indication of the base station according to which way. Specifically, the configuration information sent by the base station may be obtained, and the resource occupation mode may be determined according to the configuration information.

In addition, in this embodiment, the first information may be transmitted in any form, for example, the first information may be transmitted in one or more of the following manners: broadcast messages, including MIB, SIB1(RMSI), SIB; RRC-specific signaling; DCI messages (carried on PDCCH or GC-PDCCH); MAC CE messages, etc.

In this embodiment, the determination method of the resource occupation location may be determined according to the configuration information received from the base station, so that the determination method is more explicit.

In an embodiment of the present application, it may also be determined whether to determine the resource occupying position in the candidate positions according to an indication of the base station.

Specifically, in this embodiment, configuration information may be obtained, and whether to determine the resource occupation location is determined according to the configuration information. If it is determined that the resource occupying position is to be determined, the resource occupying positions in all candidate positions in the synchronization signal block transmission window may be determined according to the position configuration information, that is, the method for resource occupying positions in the foregoing embodiment may be performed.

In the embodiment of the present application, the configuration information related to different embodiments may be the same or different, and if the configuration information is the same, the information used in the configuration information may be different in different embodiments.

The application also provides an embodiment, which is applied to the base station side. Specifically, referring to fig. 14, the embodiment includes:

step S510: and sending the position configuration information to the terminal equipment. The location configuration information includes the configuration situation of the candidate location of the base station for transmitting the synchronization signal block, and is used for indicating the terminal device to determine the resource occupation location in all the candidate locations in the synchronization signal block transmission window according to the location configuration information, where the candidate location is the location for transmitting the synchronization signal block. For specific description of the location configuration information, reference may be made to the foregoing embodiments, which are not described herein again.

Step S520: and in the transmission window, when the listen before talk is successful (LBT is successful), corresponding unsuccessfully transmitted synchronization signal blocks are transmitted to the terminal equipment from the nearest candidate position.

At the candidate positions corresponding to the sending of the synchronous signal blocks, the wave velocity directions of the synchronous signal blocks sent by each candidate position are different, so that the same synchronous signal block can only be sent at the corresponding candidate position, and the candidate positions corresponding to the same synchronous signal block have quasi co-location parameters.

Therefore, when the base station LBT succeeds, indicating that the synchronization signal block can be transmitted, the synchronization signal block is transmitted from the nearest candidate position where the synchronization signal block needs to be transmitted. The candidate position of the nearest synchronization signal block needing to be transmitted corresponds to the synchronization signal block needing to be transmitted, and the synchronization signal block is not transmitted yet.

For example, as shown in fig. 1, the base station may not transmit the synchronization signal block in the candidate positions after LBT failure, and may transmit the synchronization signal block in the candidate positions after LBT success if the synchronization signal block needs to be transmitted. If fig. 1 shows candidate positions in a transmission window, the base station transmits at most 2 synchronization signal blocks in a window, and the configured synchronization signal block is transmitted only one corresponding position configuration information is 10, then the synchronization signal block may be transmitted at the nearest candidate position after the successful LBT in fig. 1.
