In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the embodiment of the present application, transmission of a Synchronization Signal Block (SSB) (SS/PBCH Block) is involved, and the following description will be made of the Synchronization Signal Block.

The SSB may include a Synchronization Signal (SS) and a Physical Broadcasting Channel (PBCH). The SSB may cover the entire cell in a multi-beam scanning manner, so as to facilitate UE reception in the cell. Multi-beam transmission of synchronization signal blocks is achieved by defining SS/PBCH cluster sets. An SS burst set (also referred to as an SS burst) contains one or more SSBs. One SSB is used to carry the synchronization signal and the broadcast channel of one beam. Thus, one SS/PBCH burst set may contain synchronization signals for the number of SSBs within the cell. The maximum number of SSBs may be related to the frequency band of the system.

For example, for frequency bands within the frequency range of 3GHZ, the maximum number is equal to 4. For frequency bands within the frequency range 3GHZ to 6GHZ, the maximum number is equal to 8. For frequency bands above the frequency range 6GHZ, the maximum number is equal to 64.

An SSB may contain a Primary Synchronization Signal (PSS) of one symbol, a Secondary Synchronization Signal (SSS) of one symbol, and a NR-PBCH (New Radio Access Technology-Physical broadcast channel) of two symbols, for example, as shown in fig. 2. Wherein, the PBCH may also be transmitted while the PSS is transmitted on the PSS symbol.

All SSBs in the SS/PBCH burst set may be transmitted within a time window of 5ms and repeatedly transmitted with a certain period, and the period is configured by parameters of higher layers (e.g., SSB-timing), including 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc.

The distribution of the time slots of the SSBs in different subcarrier spacings and frequency bands can be as shown in fig. 3, wherein in fig. 3, the dark gray filled portion can be the transmission position of the SSB. Taking the 15kHz subcarrier spacing and the maximum number of SSBs as 4 as an example, one slot (slot) contains 14 symbols (symbols), which can carry two SSBs. The 4 SSBs are distributed in the first two slots within the 5ms time window. Wherein L is the maximum number of SSBs, and the number of actually transmitted SSBs may be smaller than L. Wherein, the base station may notify the actually transmitted SSB in a bit mapping manner.

For example, in a frequency band below 6GHz of the licensed spectrum, there are at most 8 SSBs included in the SSB burst, and the base station may notify the UE of a specific SSB transmission position through 8 bits of information in a broadcast manner, where each bit represents whether one SSB is transmitted or not, so that the UE performs rate matching.

The method and the device can be used for the unlicensed spectrum. Unlicensed spectrum is a spectrum divided by countries and regions that can be used for communication by radio devices, and is generally considered to be a shared spectrum, i.e., a spectrum that can be used by communication devices in different communication systems as long as the regulatory requirements set on the spectrum by the country or region are met, and no proprietary spectrum license may be applied to the government. In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, in european regions, the communication device follows the principle of "listen-before-talk" (LBT), that is, before the communication device performs signal transmission on the channel of the unlicensed spectrum, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the unlicensed spectrum Channel cannot exceed the Maximum Channel Occupancy Time (MCOT).

In NR unlicensed (unilicensed) technology, transmission may be achieved using NR technology over an unlicensed spectrum. In the SSB transmission process, the SSB transmission time shown in fig. 3 may not be able to successfully transmit the SSB due to the possibility of LBT failure. Therefore, in the embodiment of the present application, the sending opportunity of the SSB may be increased, and the sending time of the new SSB may be defined.

Specifically, in consideration of uncertainty of obtaining the channel use right on the unlicensed spectrum, within a transmission window, the number Y of candidate transmission positions of the SSBs configured by the network device is greater than the maximum number L of SSBs that the network device can transmit within the transmission window.

That is, for each transmission window, the network device may determine to transmit L SSBs using available ones of the Y candidate transmission positions according to the detection result of LBT within the transmission window, and the used candidate transmission positions may be different within different transmission windows. Therefore, consideration needs to be given to how to indicate candidate transmission positions used within one transmission window.

in 220, the network device transmits second information indicating a first starting position, where the first starting position is a corresponding starting position of the M synchronization signal blocks within a transmission window, where the transmission window includes N candidate transmission positions, the M synchronization signal blocks correspond to M candidate transmission positions, and M is smaller than N.

Fig. 5 is a schematic flow chart diagram of a wireless communication method 300 according to an embodiment of the application. The method 300 includes at least some of the following.

In 310, a terminal device receives first information, the first information indicating transmission information of M synchronization signal blocks, the transmission information indicating whether the synchronization signal blocks are transmitted or not;

in 320, the terminal device receives second information, where the second information indicates a first starting position, where the first starting position is a corresponding starting position of the M synchronization signal blocks within a transmission window, where the transmission window includes N candidate transmission positions, the M synchronization signal blocks correspond to M candidate transmission positions, and M is smaller than N.

Optionally, the terminal device may determine, according to the first information and the second information, a position of a synchronization signal block actually sent in the transmission window, so that rate matching for downlink data reception may be performed.

Specific implementations of

methods

200 and 300 are described in detail below to facilitate a clearer understanding of the present application.

Optionally, in this embodiment of the present application, the M synchronization signal blocks indicated by the first information may be the maximum synchronization signal block allowed to be transmitted within one transmission window. Each synchronization signal block corresponds to an SSB index, and different synchronization signal blocks correspond to different SSB indexes.

Alternatively, in this embodiment, the M synchronization signal blocks may be all synchronization signal blocks included in the SS burst.

It should be understood that, in the embodiment of the present application, M synchronization signal blocks may correspond to M candidate transmission positions,

alternatively, in this embodiment of the present application, the transmission window may be referred to as a Discovery Reference Signal (DRS) transmission window. The transmission window may include N candidate transmission positions, each of which may be used to transmit an SSB. The two adjacent candidate transmission positions included in the transmission window may be consecutive or non-consecutive in the time domain (e.g., may be separated by at least one symbol, at least one slot, etc.).

Optionally, in this embodiment of the present application, the SSB index corresponding to each candidate transmission position in the transmission window may not be fixed. At this time, from any one of the candidate transmission positions, the transmission of SSB may be performed at the candidate transmission position in the order of SSB index 0 to SSB index M-1. The M synchronization signal blocks may correspond to the M candidate transmission positions, and even if a certain synchronization signal block does not need to be transmitted, at this time, for a next synchronization signal block, the transmission position corresponding to the certain synchronization signal block may be skipped, and the next synchronization signal block is transmitted at the candidate transmission position corresponding to the next synchronization signal block, that is, the transmission position of the certain synchronization signal block is not occupied. Of course, the embodiments of the present application are not limited thereto, and for example, even if a certain synchronization signal block does not need to be transmitted, in this case, a next synchronization signal block may not need to skip one candidate transmission position.

In this embodiment of the present application, the SSB index corresponding to each candidate transmission position in the transmission window may also be fixed. That is, for a particular candidate transmission location, it corresponds to a particular SSB index. For a particular SSB index, its corresponding candidate transmission position within the transmission window may occur periodically.

For example, as shown in fig. 6, 64 candidate transmission positions may be included in one transmission window (the first row of numbers in fig. 6 represents the candidate transmission positions), M may be equal to 8, the SSB index may have a value from 0 to 7, each candidate transmission position may correspond to a specific SSB index (the second row of numbers represents the SSB index corresponding to each candidate transmission position), as can be seen from fig. 6, the candidate transmission position corresponding to each SSB index is periodic, and the number of the corresponding candidate transmission positions is 8.

Optionally, in this embodiment of the present application, the M candidate transmission positions are consecutive within the transmission window. For example, as shown in fig. 6, for 8 candidate transmission positions, the 8 candidate transmission positions are consecutive regardless of which candidate transmission position starts, and may correspond to 8 indexed synchronization signal blocks.

Optionally, in this embodiment of the present application, the transmission window includes P candidate starting positions, where the candidate starting position is one of the N candidate sending positions that can be used as starting positions of M candidate sending positions corresponding to the M synchronization signal blocks, the P candidate starting positions include the first starting position, and P is greater than 1 and less than or equal to N.

For example, as shown in fig. 6, one candidate start position may appear every 4 candidate transmission positions (only a part of the candidate start positions are shown in the figure), and from this candidate start position, transmission of 8-indexed synchronization signal blocks may be performed (only a part of the synchronization signal blocks may actually be transmitted).

If the embodiment of the present application is used for unlicensed spectrum, LBT operation may be performed before the candidate starting position, and if LBT operation is successful, SSB transmission may be started with the candidate starting position. If LBT fails, it is necessary to wait until the next candidate starting position and perform LBT operation before the next candidate starting position.

For example, as shown in fig. 6, if LBT operations performed at the first 5 candidate start positions fail, and LBT performed before the sixth candidate start position succeeds, then SSB transmission may be performed at the sixth candidate start position.

Optionally, in this embodiment of the application, the number of candidate transmission positions spaced between every two candidate starting positions in the P candidate starting positions is the same.

For example, as shown in fig. 6, the number of candidate transmission positions per interval between two candidate start positions is 4.

Optionally, in this embodiment of the application, the number of candidate transmission positions spaced between every two candidate starting positions in the P candidate starting positions is less than or equal to M.

For example, as shown in fig. 6, the number of candidate transmission positions spaced between every two candidate start positions is 4, and 4 is smaller than 8. In this implementation manner, the problem of wasted transmission positions due to the fact that the candidate transmission positions spaced between every two candidate start positions are larger than M can be avoided.

Optionally, in this embodiment of the present application, M is an integer multiple of the number of candidate transmission positions spaced between every two starting candidate positions.

For example, as shown in fig. 6, the number of candidate transmission positions spaced between every two candidate start positions is 4, and 8 is 2 times 4. In this implementation manner, it can be achieved that M candidate transmission positions corresponding to M synchronization signal blocks are equal to a candidate transmission position between two candidate transmission positions (which may be adjacent or non-adjacent). The candidate sending positions corresponding to the specific synchronous signal blocks can be repeatedly appeared, and the problem of waste of the candidate sending positions caused by the fact that the candidate sending positions do not correspond to any synchronous signal blocks can be avoided.

Optionally, in this embodiment of the application, the transmission window starts from the last candidate starting position of the P candidate starting positions, and includes a number of candidate transmission positions that is greater than the number of candidate transmission positions spaced between every two candidate starting positions of the P candidate starting positions.

Optionally, in this embodiment of the present application, the transmission window starts from a last candidate starting position in the P candidate starting positions, and includes a number of candidate transmission positions greater than or equal to M.

For example, as shown in fig. 6, the corresponding candidate transmission position at the candidate transmission position 56 may be taken as the last candidate start position within the transmission window. Thereby, all synchronization signal blocks of the M synchronization signal blocks to which the remaining candidate transmission positions at the last candidate start position cannot correspond can be avoided.

Optionally, the P candidate starting positions are uniformly or non-uniformly distributed within the transmission window.

In case of non-uniform distribution, it may be achieved that e.g. some candidate transmission positions need to be used as synchronization signal blocks for other scenes.

It should be understood that, in the embodiment of the present application, each candidate sending position in the transmission window may be taken as a candidate starting position, for example, as shown in fig. 6, when LBT performed before the sending time corresponding to SSB index 0 fails, channel sensing may be performed continuously, channel sensing may be performed at the sending time corresponding to SSB index 1, if LBT fails, LBT performed before the sending time corresponding to SSB index 2 succeeds, the remaining SSBs are sent from SSB index 2, and after SSB index 7 is sent,

SSB indexes

0 and 1 that have not been successfully sent before are sent next.

Optionally, in this embodiment of the present application, the first information indicates the transmission information of the M synchronization signal blocks in a bit mapping manner.

Specifically, the first information indicates the transmission information in an index order of the M synchronization signal blocks. At this time, the first information may be transmitted in a non-dynamic manner, for example, through an RRC message, system information, or a broadcast message.

Since the first information is transmitted non-dynamically, the network device cannot predict the positions where the channel sensing is successful, for example, as shown in fig. 6, some starting positions are the starting positions corresponding to the index 4, and some starting positions are the positions corresponding to the index 0, so the network device cannot indicate whether to transmit the transmission information of each synchronization signal block in the order of the corresponding candidate transmission positions. The transmission information of the synchronization signal block can be indicated by the indexes of the M synchronization signal blocks.

For example, as shown in fig. 6, it is assumed that the starting position of LBT sensing success is 20, although the actual transmission sequence of SSB burst in the figure is 4, 5,6, 7, 0,1,2, 3. The 8-bit mapping scheme is indicated by the index order of SSBs, and for example, 11100110 indicates SSB transmission where the SSB index is 0,1,2,5, and 6, and SSB transmission where the SSB index is 3,4, and 7.

Optionally, in this embodiment of the present application, the first information indicates the transmission information through the number of actually transmitted synchronization signal blocks in the M synchronization signal blocks or an end position of the actually transmitted synchronization signal blocks in the M candidate transmission positions.

At this time, the candidate transmission positions occupied by the actually transmitted synchronization signal block include: at least one candidate transmission position in the M candidate transmission positions that is continuous with the first start position as a start point.

Specifically, the SSBs are transmitted on the unlicensed spectrum, and due to the limitation of the occupied time of the channel, the preferred transmission mode is to continuously transmit the SSBs, that is, the actually transmitted SSBs are sequentially and continuously transmitted in front of 8 positions in the SSB burst. Thus, the first information may include information on the number of SSBs actually transmitted, i.e., may indicate the actual transmission location of the SSBs. At this point, if M equals 8, the first message only needs 3 bits to indicate 1-8 actual sending SSBs.

Optionally, in this embodiment of the application, the second information indicates the first starting position by a position of the first starting position among the P candidate starting positions. For example, assuming that there are 16 candidate start positions, it may be indicated by 4 bits of information that the first start position is the fourth candidate start position among the 16 candidate start positions.

For example, as shown in fig. 6, there are 16 possible start positions of the SSB burst, and there are 4 bits of indication information indicating the start positions. Inside the SSB burst, the position of the actually transmitted SSB is indicated by means of 8-bit mapping. It is noted that the order of SSB indices indicated by the bitmap is still 0-7, although the actual order of SSB burst transmission is 4, 5,6, 7, 0,1,2, 3 in the figure. The 8-bit bitmap order may be an SSB index order, for example, 11100110 indicates that SSB transmission with SSB index of 0,1,2,5, and 6 and SSB transmission with SSB index of 3,4, and 7 do not. In combination with the SSB burst start position indication 0110, it indicates the 6 th position among the possible start positions defined within the DRS window, which is the start position of the actually transmitted SSB burst. Through these two indications, the actual transmission location of the SSB within the DRS window can be obtained.

Optionally, in this embodiment of the application, the second information is carried by a physical downlink control channel PDCCH sent in the search space associated with the first starting position, by a sequence associated with the first starting position, or by a reference signal associated with the first starting position.

Specifically, the start position indication information (second information) of the SSB burst is indicated by a channel or a signal associated with the start position, and the UE obtains the start position of the SSB burst by detecting the indication information or the signal itself carried by the channel. Specifically, each possible starting position in fig. 6 is associated with one PDCCH search space, and the UE obtains the DCI carried by the PDCCH by detecting the corresponding search space, and obtains whether the associated starting position is the actual starting position of the SSB burst. The PDCCH may be a group common PDCCH, and the search space is a common search space. The DCI carries 1-bit indication information, for example, 1 indicates that the associated start position is an actual start position, and 0 indicates that the associated start position is not an actual start position. The indication information may also be a signal associated with the start position, such as a sequence, a reference signal, etc., and the UE obtains the second information of the actual start position of the SSB burst according to the detection of the signal.

Optionally, in this embodiment of the present application, the first information is carried through a PDCCH, system information, a broadcast message, or Radio Resource Control (RRC) signaling.

Optionally, in this embodiment of the present application, the first information and the second information may be sent in the same Physical Downlink Control Channel (PDCCH) or different PDCCHs.
