Description

Information sending method, receiving method and device

Technical Field

The present disclosure relates to communications technologies, and in particular, to an information sending method, an information receiving method, and an information sending device.

Background

With the continuous progress of radio technology, various radio services emerge in large quantities, and the spectrum resources supported by the radio services are limited, so that the spectrum resources between 300MHz and 3GHz mainly used by the traditional commercial communication show a very tight situation in the face of the continuous increase of the bandwidth requirements of people, and the requirements of the future wireless communication cannot be met.

In future wireless communication, a carrier frequency higher than that used by a fourth generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, 70GHz, and the like, and such a high-frequency channel has the disadvantages of large free propagation loss, easy absorption by oxygen, large influence by rain attenuation, and the like, and seriously affects the coverage performance of the high-frequency communication system. However, since the carrier frequency corresponding to the high-frequency communication has a shorter wavelength, it can be ensured that more antenna elements can be accommodated in a unit area, and the more antenna elements mean that the antenna gain can be increased by adopting a beamforming method, thereby ensuring the coverage performance of the high-frequency communication.

After the beam forming method is adopted, the transmitting end can concentrate the transmitting energy in a certain direction, and the energy in other directions is little or none, that is, each beam has own directivity, each beam can only cover the terminal in a certain direction, and the transmitting end, that is, the base station, needs to transmit the beam in dozens or even hundreds of directions to complete the all-round coverage. In the prior art, a preliminary beam direction measurement and identification is performed during an initial network access process of a terminal, and with a structure as shown in fig. 1, each grid is defined as a synchronization signal block (SS block), and in each beam scanning time block, synchronization signals, system information, and optionally a beam/port measurement reference signal may be transmitted on a plurality of beams or ports according to the number of radio frequency chains of a base station. The terminal identifies the preferred downlink transmitting beam or port by measuring the synchronous signal, acquiring the system information and measuring the optional measurement reference signal, acquires the cell basic information and accesses the configuration information, thereby accessing the network. One or more synchronous signal blocks form a synchronous signal window (SS burst), one or more synchronous signal windows form a synchronous signal window group (SS burst set), and the transmitting beam at the base station side is polled once in the period of the SS burst set, so that the terminal can measure and identify the preferred beam or port and realize the downlink synchronization with the network.

In such a process, as the operating frequency band of the system increases, the required beamforming gain also increases, which means that a more "narrow" beam is required to cover the expected range, the number of beams may reach tens or even hundreds, and further, the number of the synchronization signal blocks also needs to be correspondingly increased, and the total length occupied by the synchronization signal blocks will be very long. Because the polling of the full beam is required to be realized according to a certain rule in the synchronization signal block, for the transmission of the conventional data, the transmission of the data is limited by the number of radio frequency chains, and the data transmission cannot be flexibly scheduled according to the requirement during the transmission of the synchronization signal block. Therefore, it is considered to map SS blocks into a discontinuous manner. The method has the advantages that the limitation of data flexibility is reduced, and meanwhile, a new problem is introduced, namely due to the irregular mapping of the SS block, a terminal in a link state or an idle state in the prior art cannot know the position of actually transmitting the SS block, so that on one hand, each SS block cannot be accurately found by the terminal in the link state or the idle state, and when the terminal measures by using a synchronous signal or a reference signal carried in the SS block, the measurement overhead of the terminal is increased, and the measurement accuracy is influenced; on the other hand, for the SS block which is not occupied, the terminal needs to receive potential control and data, and the number of times of blind detection of the downlink control information by the terminal is increased because the actual position of the SS block cannot be obtained.

The synchronization signal block resource is used for mapping one or more of a synchronization signal block, a mini time slot, an uplink control symbol, a downlink control symbol, a data symbol and a guard interval. That is, the synchronization signal block resource can be considered as a potential synchronization signal block, namely: possibly for transmitting synchronization signal blocks, and possibly also for transmitting other symbols.

Wherein the synchronization signal block may include: synchronization signals, system information, and optionally beam/port measurement reference signals.

For the first type of synchronization signal block resource, the synchronization signal block is mapped on the first type of synchronization signal block resource in a continuous or discontinuous manner, so the position of the synchronization signal block can be flexibly configured, for example, configured as required.

In this embodiment, a bitmap (bitmap) mode is adopted for the flexibly configurable synchronization signal blocks, and a number of synchronization signal blocks is adopted for the sequentially mapped synchronization signal blocks. Therefore, the position of the currently transmitted synchronous signal block can be effectively indicated, and compared with a full bitmap mode (namely, 1-bit information indication is used for each synchronous signal block), the overhead of information indication is effectively reduced.

The present disclosure is illustrated by the following examples.

Example one

The configuration structure of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 6, and is specifically described below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 4 SS bursts (one for every 5 ms), the duration is 0.5ms, and within one SS burst, the SS block resource mapping manner from the SS block to the SS block in the data transmission slot is as follows: the mapping of a part of SS blocks comprises control symbols, such as SS blocks 0, 3, 6, 7, 10, 13, and the like, and the structure of a Slot can be flexibly configured or predefined, for example, Slot0 is a pure downlink Slot and is used for downlink control and downlink data transmission; the slot is a self-contained time slot, and includes downlink control, downlink data, and uplink control, where the uplink control is used for uplink feedback of the terminal, and a guard interval (GP) of a certain length needs to be reserved between the downlink data and an uplink control symbol.

The number of potential SS blocks (namely SS block resources) in one SS burst is 14, the potential SS blocks are mapped on 4 data transmission time slots (slot0-slot3), and the internal structures of the 4 SS bursts are consistent. Thus, the total number of potential SS blocks in the SS burst set range is 56. The potential SS block here refers to the resource that may be used to transmit the SS block, whether actually transmitted is determined by the network side.

In the configuration illustrated in fig. 6, SS bursts are evenly distributed within SS burst set, i.e. one SS burst every 5 ms. The SS bursts may also be configured non-uniformly within the SS burst set, for example, 4 SS bursts are concentrated on a part of resources of the SS burst set, for example, transmission is configured in the first 10ms, and then no SS burst is configured in the last 10 ms. Alternatively, all SS bursts within an SS burst set are configured consecutively.

The potential SS blocks are numbered uniformly within the SS burst set, SS blocks 0-13 being shown, SS blocks 14-55 not being shown.

When the SS block is mapped to the data transmission time slot, the SS block resources are divided into two types according to the type of the symbol corresponding to each SS block:

first type (type a): the symbols corresponding to SS block include control symbols, and type a includes: such as SS block0, 3, 6, 7, 10, 13), similarly, the last three SS bursts also contain 6 type a SS block resources, respectively, and there are 24 type a SS block resources in a SS burst set.

Second type (type B): in SS block resources other than the first type, symbols corresponding to SS blocks only include data symbols (gray is a data symbol in the figure), and type B includes:

SS block

1, 2, 4, 5, 8, 9, 11, 12. Similarly, the last three SS bursts also contain 8 type B SS block resources, respectively, and there are 32 type B SS block resources in a SS burst set.

Since type a SS block resources may be used to transmit control information as needed, such as scheduling of subsequent data transmission resources, or feedback on previous data reception, these requirements typically have a fixed timing relationship, and when such requirements are met, the resources cannot be actually used to transmit SS blocks. Therefore, the type a SS block resource can be flexibly configured whether to transmit the SS block. Indicating whether the resource of each SS block is actually transmitted by a synchronization signal block or not in a bitmap mode, wherein the bitmap mode means that each bit indicates the resource occupation state of one SS block, and can be predefined as 0 for not transmitting the SS block and 1 for transmitting the SS block;

for example, the resource states of the 24 type A SS blocks are: 010000101010000000000110. as described above, the numbers of the 24 type a SS blocks are well known to the base station and the terminal, and therefore, the SS block numbers corresponding to each bit are also well known to both sides. E.g., the first bit corresponds to SS block0, the second bit corresponds to SS block3, and so on.

the type B SS blocks are data transmission resources, whether these resources are scheduled is determined by the base station, and whether these resources are transmitted has no limitation in timing relationship. Thus, the class of SS blocks may be predefined to be mapped onto the class of resources sequentially in an order, e.g., from front to back. This only indicates the number of actual transmissions of this type of SS block, which SS blocks are actually transmitted. For example, since 32 type B SS blocks are present in the current SS burst set, the indication information occupies 5 bits, and the number of the current type B SS blocks is 16, the indication information of the type B SS block is 10000.

So far, indication information of actual transmission conditions of the two types of SS blocks is obtained. The information is concatenated to obtain 29 bits of complete indication information, for example: 010000101010000000000110 (for type A)10000 (for type B). The network side can inform the terminal in a certain way. The notification may be performed in any of the following ways: 1. the indication information is contained in a system broadcast message, where the system broadcast message may be primary system information carried in a Physical Broadcast Channel (PBCH), or remaining minimum system information (remaining minimum SI) carried in a physical downlink shared channel, or other system information (other SI); the minimum system information refers to system information necessary for a terminal initial access process, and comprises main system information and residual minimum system information; the main system information refers to system information carried in a physical broadcast channel; the residual minimized information refers to residual system information except the main system information in the minimized system information; the other system information refers to system information other than the initial access-related parameters. 2. After the terminal accesses the network, the network side notifies the terminal through a Radio Resource Control (RRC) dedicated message.

The meaning of each bit in the indication information is predefined, so that the terminal can obtain the position of the actual transmission SS block after successfully decoding the indication information.

In this embodiment, a synchronization signal block resource capable of carrying a control symbol is determined as an SS block resource of a first type (type a); a synchronization signal block resource that can carry data symbols is determined as an SS block resource of a second type (type B). The first type (type a) and the second type (type B) of synchronization signal block resources may also be defined in other principles, for example, the network side predefines even number SS block resources as type a SS block resources, and the classification rule is predefined (i.e., the network side is well known to the terminal), or the network side determines and notifies the terminal. Other classification rules are not excluded.

Example two

The configuration structure of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 7, and is specifically described below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 4 SS bursts (one for every 5 ms), the duration is 0.5ms, and within one SS burst, the mapping manner of the SS block to the data transmission slot is as follows: fixedly reserving a front part symbol of each Slot, for example, reserving two symbols, wherein the reserved symbols can be used as downlink control symbols or configured as mini slots (used for scheduling and transmitting data); the potential SS blocks are mapped continuously from the reserved symbols, 3 SS blocks are mapped continuously under the slot configuration of 14 symbols, and for the last SS block of the three SS blocks, the symbols where the control is located, such as SS blocks 2, 5, 8 and 11, are included. These SS block resources containing control symbols may also be reserved, and if reserved, may be configured as a guard interval and uplink control, or as mini-slots. In the mapping mode, the mapping modes of the SS blocks in the slots are the same, the structures are relatively uniform, and the mapping across the slots is not involved.

In one SS burst, the number of potential SS blocks (i.e., SS block resources) is 12, and the potential SS blocks are mapped on 4 data transmission slots (slot0-slot3), and the internal structures of the 4 SS bursts are consistent. Thus, the total number of potential SS blocks in the SS burst set range is 48. The potential SS block here refers to the resource that may be used to transmit the SS block, whether actually transmitted is determined by the network side.

In the configuration illustrated in fig. 7, SS bursts are evenly distributed within SS burst set, i.e. one SS burst every 5 ms. The SS bursts may also be configured non-uniformly within the SS burst set, for example, 4 SS bursts are concentrated on a part of resources of the SS burst set, for example, transmission is configured in the first 10ms, and then no SS burst is configured in the last 10 ms. Alternatively, all SS bursts within an SS burst set are configured consecutively.

The potential SS blocks are numbered uniformly within the SS burst set, SS blocks 0-23 being shown, SS blocks 24-47 not being shown.

When the SS block is mapped to a data transmission time slot, the SS block resources are divided into two types according to the type of the symbol corresponding to each SS block:

first type (type a): the symbol corresponding to the SS block resource includes a control symbol, and type a includes: such as SS block2, 5, 8, 11), similarly, the last three SS bursts also contain 4 type a SS block resources, respectively, and there are 16 type a SS block resources in a SS burst set.

Second type (type B): symbols corresponding to SS block resources only include data symbols (gray in the figure is data symbols), and type B includes: SS block0, 1, 3, 4, 6, 7, 9 and 10. Similarly, the last three SS bursts also contain 8 type B SS block resources respectively, and there are 32 type B SS block resources in a SS burst set.

Since the type a SS block resource may be used to transmit uplink control information as needed, for example, for feedback on previous downlink data reception, these requirements usually have a fixed timing relationship, and when the above-mentioned similar requirements exist, the resource cannot be used to actually transmit the SS block. Therefore, the type a SS block resource can be flexibly configured whether to transmit the SS block. Indicating whether the resource of each SS block is actually transmitted by a synchronization signal block or not in a bitmap mode, wherein the bitmap mode means that each bit indicates the resource occupation state of one SS block, and can be predefined as 0 for not transmitting the SS block and 1 for transmitting the SS block;

for example, the resource states of 16 type a SS blocks are: 0100001010100000. as described above, the numbers of 16 type a SS blocks are known to the base station and the terminal, and therefore, the SS block numbers corresponding to each bit are also known to both sides. E.g., the first bit corresponds to SS block2, the second bit corresponds to SS block5, and so on.

the type B SS block resources are data transmission resources, whether these resources are scheduled is determined by the base station, and there is no limitation on whether these resources are transmitted in a timing relationship. Thus, the class of SS blocks may be predefined to be mapped onto the class of resources sequentially in an order, e.g., from front to back. This only indicates the number of actual transmissions of this type of SS block, which SS blocks are actually transmitted. For example, since 32 type B SS blocks are present in the current SS burst set, the indication information occupies 5 bits, and the number of the current type B SS blocks is 16, the indication information of the type B SS block is 10000.

So far, indication information of actual transmission conditions of the two types of SS blocks is obtained. The information is concatenated to obtain 21 bits of complete indication information, for example: 0100001010100000 (for type A)10000 (for type B). The network side will inform the terminal in a certain way. The notification may be performed in any of the following ways: 1. the indication information is contained in a system broadcast message, where the system broadcast message may be primary system information carried in a physical broadcast channel PBCH, or remaining minimized system information carried in a physical downlink shared channel, or other system information; 2. after the terminal accesses the network, the network side notifies the terminal through the RRC dedicated message.

EXAMPLE III

The configuration structure of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 8, and is specifically described below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 4 SS bursts (one for every 5 ms), the duration is 0.5ms, and within one SS burst, the mapping manner of the SS block to the data transmission slot is as follows: fixedly reserving a front part symbol of each Slot, for example, reserving two symbols, wherein the reserved symbols can be used as downlink control symbols or configured as mini slots (used for scheduling and transmitting data); the potential SS blocks are mapped continuously from the reserved symbols, and 3 SS blocks are mapped continuously under the slot configuration of 14 symbols, and for the last SS block of the three SS blocks, control symbols such as SS blocks 2, 5, 8 and 11 are included. These SS block resources containing control symbols may also be reserved, and if reserved, may be configured as a guard interval and uplink control, or as mini-slots. In the mapping mode, the mapping modes of the SS blocks in the slots are the same, the structures are relatively uniform, and the mapping across the slots is not involved.

In the configuration illustrated in fig. 8, SS bursts are evenly distributed within SS burst set, i.e. one SS burst every 5 ms. The SS bursts may also be configured non-uniformly within the SS burst set, for example, 4 SS bursts are concentrated on a part of resources of the SS burst set, for example, transmission is configured in the first 10ms, and then no SS burst is configured in the last 10 ms. Alternatively, all SS bursts within an SS burst set are configured consecutively.

The difference from the second embodiment is that SS block resources are not uniformly numbered in SS burst set, but uniformly numbered in SS burst range, and SS bursts are uniformly numbered in SS burst set (namely SS burst 0, 1, 2, 3), under the numbering rule, SS block index/number in SS burst set needs to be uniquely indicated by a combination of SS burst index and SS block index in SS burst, SS burst 0-11 in SS burst 0 and SS burst 1 are shown in the figure, SS block of SS burst 2, SS burst 3 is the same as the first two SS bursts, and is not shown in the figure.

When the SS blocks are mapped to the data transmission time slots, the SS blocks are divided into two types according to the type of the symbol corresponding to each SS block:

first type (type a): the symbols corresponding to the SS block resource include control symbols, and type a includes: SS block2, 5, 8, 11 within each SS burst), and similarly, there are 16 type a SS block resources within one SS burst set.

Second type (type B): symbols corresponding to SS block resources only include data symbols (gray in the figure is data symbols), and type B includes: SS block0, 1, 3, 4, 6, 7, 9, 10 within each SS burst. There are 32 type B SS block resources within one SS burst set.

the resource states of the 16 type A SS blocks are as follows: 0100001010100000. as described above, the numbers of 16 type a SS blocks are known to the base station and the terminal, and therefore, the SS block numbers corresponding to each bit are also known to both sides. If the first bit corresponds to the SS block2 in SS burst 0, the second bit corresponds to the SS block5 in SS burst 0, and so on.

the type B SS block resources are data transmission resources, whether these resources are scheduled is determined by the base station, and whether these resources are transmitted or not has no limitation of timing relationship. Thus, the class of SS blocks may be predefined to be mapped onto the class of resources sequentially in an order, e.g., from front to back. This only indicates the number of actual transmissions of this type of SS block, which SS blocks are actually transmitted. For example, since there are 32 type B SS blocks in the current SS burst set, the indication information occupies 5 bits, and the current number of type B SS blocks is 16, the indication information of type B SS block is 10000.

So far, indication information of actual transmission conditions of the two types of SS block resources is obtained. The information is concatenated to obtain 21 bits of complete indication information, for example: 0100001010100000 (for type A)10000 (for type B). The network side will inform the terminal in a certain way. The notification may be performed in any of the following ways: 1. the indication information is contained in a system broadcast message, where the system broadcast message may be primary system information carried in a Physical Broadcast Channel (PBCH), or remaining minimized system information carried in a physical downlink shared channel (pdcch), or other system information; 2. after the terminal accesses the network, the network side notifies the terminal through the RRC dedicated message.

Example four

The configuration structure of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 9, and is specifically described below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 4 SS bursts (one for every 5 ms), the duration is 0.5ms, and within one SS burst, the mapping manner of the SS block to the data transmission slot is as follows: the beginning part symbol and the ending part symbol of each Slot are fixedly reserved. For example, the first 1 symbol of each slot is reserved (the reserved symbol may be used as a downlink control symbol or configured as a mini slot (used for scheduling and transmission of data)), and the last 1 symbol (the reserved symbol is configured as a guard interval and uplink control, or configured as a mini slot); and the potential SS blocks start to be mapped continuously after the symbols reserved in front of the slots are finished, and 3 SS blocks can be mapped continuously under the configuration of the slots with 14 symbols.

In the configuration illustrated in fig. 9, SS bursts are evenly distributed within SS burst set, i.e. one SS burst every 5 ms. The SS bursts may also be configured non-uniformly within the SS burst set, for example, 4 SS bursts are concentrated on a part of resources of the SS burst set, for example, transmission is configured in the first 10ms, and then no SS burst is configured in the last 10 ms. Alternatively, all SS bursts within an SS burst set are configured consecutively.

The potential SS blocks are numbered uniformly within the SS burst set, SS blocks 0-11 being shown, SS blocks 12-47 not being shown. Note: similar to the third embodiment, the SS block may also be numbered uniformly within the SS burst, and the SS burst is numbered uniformly within the SS burst set, and the SS block is uniquely indicated by the SS block number and the SS burst number.

SS block resources are divided into two categories according to a predefined manner: the system predefines the following rules (the rules given here indicate examples, other predefined rules also apply, e.g., the network side predefines even SS block resources as type a SS block resources, and the classification rules are predefined (i.e., the network side is well known to the terminal), or the network side determines and informs the terminal): the last SS block in each slot can flexibly configure whether the SS block is actually transmitted or not; the rest SS block resources need to be mapped with SS blocks in sequence from front to back. Then there are:

first type (type a): the SS block resources include: like SS block2, 5, 8 and 11, the last three SS bursts also respectively contain 4 type a SS block resources, and 16 type a SS block resources are shared in one SS burst set.

Second type (type B): the method comprises the following steps: SS block0, 1, 3, 4, 6, 7, 9 and 10. Similarly, the last three SS bursts also contain 8 type B SS block resources, respectively, and there are 32 type B SS block resources in a SS burst set.

The SS block resource can be flexibly configured to the type A and whether the SS block resource is used for transmitting the SS block. Indicating whether the resource of each SS block is actually transmitted by a synchronization signal block or not in a bitmap mode, wherein the bitmap mode means that each bit indicates the resource occupation state of one SS block, and can be predefined as 0 for not transmitting the SS block and 1 for transmitting the SS block;

for example, the resource states of 16 type a SS blocks are: 0100001010100000. as mentioned earlier, the 16 type a SS block numbers are known to both the base station and the terminal, and therefore the SS block number for each bit is also known to both parties. E.g., the first bit corresponds to SS block2, the second bit corresponds to SS block5, and so on.

type B SS block resource: the SS blocks of the type are mapped to the resources of the type sequentially in a certain order, for example, from front to back. This only indicates the number of actual transmissions of this type of SS block, which SS blocks are actually transmitted. For example, since 32 type B SS block resources are shared in the current SS burst set, the indication information occupies 5 bits, and the number of the current type B SS block resources is 16, the indication information of the type B SS block is 10000.

So far, indication information of actual transmission conditions of the two types of SS block resources is obtained. The information is concatenated to obtain 21 bits of complete indication information, for example: 0100001010100000 (for type A)10000 (for type B). The network side will inform the terminal in a certain way. The notification may be performed in any of the following ways: 1. the indication information is contained in a system broadcast message, where the system broadcast message may be primary system information carried in a physical broadcast channel PBCH, or remaining minimized system information carried in a physical downlink shared channel, or other system information; 2. after the terminal accesses the network, the network side notifies the terminal through the RRC dedicated message.

EXAMPLE five

The configuration of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 10, and is specifically described below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 4 SS bursts (one for every 5 ms), the duration is 0.5ms, and within one SS burst, the mapping manner of the SS block to the data transmission slot is as follows: the fixed reserved SS burst begins symbol and ends symbol. For example, the first 2 symbols of each SS burst are reserved (the reserved symbols may be used as downlink control symbols or configured as mini slots (used for scheduling and transmission of data)), and the last 2 symbols (the reserved symbols are configured as guard interval and uplink control symbols or configured as mini slots); and the potential SS blocks start to be mapped continuously after the symbols reserved from the beginning of the SS burst are finished, and 13 SS blocks can be mapped continuously under the configuration of 4 continuous slots with 14 symbols.

That is, in each SS burst, the number of potential SS blocks (i.e., SS block resources) is 13, and the mapping is performed on 4 data transmission slots (slot0-slot3), and the internal structures of the 4 SS bursts are consistent. Thus, the total number of potential SS blocks in the SS burst set range is 52. The potential SS block here refers to the resource that may be used to transmit the SS block, whether actually transmitted is determined by the network side.

In the configuration illustrated in fig. 10, SS bursts are evenly distributed within SS burst set, i.e. one SS burst every 5 ms. The SS bursts may also be configured non-uniformly within the SS burst set, for example, 4 SS bursts are concentrated on a part of resources of the SS burst set, for example, transmission is configured in the first 10ms, and then no SS burst is configured in the last 10 ms. Alternatively, all SS bursts within an SS burst set are configured continuously.

The potential SS blocks are numbered uniformly within the SS burst set, SS blocks 0-12 are shown, and SS blocks 13-51 are not shown. Note: similar to embodiment 3, the SS block may also be numbered uniformly within the SS burst, and the SS burst is numbered uniformly within the SS burst set, and the SS block is uniquely indicated by the SS block number and the SS burst number.

SS blocks are divided into two categories according to predefined ways:

illustratively, the system predefines the following rules: the network side predefines even SS block resources as type a SS block resources and the classification rules are either predefined (i.e. the network side is known to the terminal) or the network side determines and informs the terminal. The network side can flexibly configure whether the type A SS block resource actually transmits the SS block; the rest SS block resources need to be mapped with SS blocks in sequence from front to back. Then there are:

within the first SS burst, the type a SS block resource comprises: SS block0, 2, 4, 6, 7. Within the second SS burst, the type a SS block resource comprises: 6 SS blocks 14, 16, 18. Similarly, the third SS burst and the fourth SS burst respectively contain 7 and 6 type a SS block resources, and one SS burst set contains 26 type a SS block resources.

type B: the method comprises the following steps: the number of odd numbered SS block resources is 26.

Whether the resource can be flexibly configured for type A SS block is used for transmitting SS block. Indicating whether the resource of each SS block is actually transmitted by a synchronization signal block or not in a bitmap mode, wherein the bitmap mode means that each bit indicates the resource occupation state of one SS block, and can be predefined as 0 for not transmitting the SS block and 1 for transmitting the SS block;

for example, the resource states of the 26 type A SS blocks are: 01000010101000000010101000. as described above, the numbers of the 26 type a SS blocks are known to the base station and the terminal, and therefore, the SS block numbers corresponding to each bit are also known to both sides. If the first bit corresponds to SS block0, the second bit corresponds to SS block2, and so on.

type B SS block resource: the SS blocks of the type are mapped to the resources of the type sequentially in a certain order, for example, from front to back. This only indicates the number of actual transmissions of this type of SS block, which SS blocks are actually transmitted. For example, since 32 type B SS blocks are shared in the current SS burst set, the indication information occupies 5 bits, and the number of the current type B SS blocks is 20, the indication information of the type B SS block is 10100.

So far, indication information of actual transmission conditions of the two types of SS block resources is obtained. The information is concatenated to obtain the complete indication information of 31 bits, for example: 01000010101000000010101000 (for type A)10100 (for type B). The network side will inform the terminal in a certain way. The notification may be performed in any of the following ways: 1. the indication information is contained in a system broadcast message, where the system broadcast message may be primary system information carried in a Physical Broadcast Channel (PBCH), or remaining minimized system information carried in a physical downlink shared channel (pdcch), or other system information; 2. after the terminal accesses the network, the network side notifies the terminal through the RRC dedicated message.

EXAMPLE six

The configuration of the synchronization signal window set SS burst set described in this embodiment is shown in fig. 11, and will be described in detail below.

In this embodiment, the SS burst set period takes 20ms as an example, and includes 2 SS bursts (one for every 10 ms), the duration is 1ms, and within one SS burst, the mapping manner of the SS block to the data transmission slot is as follows: the fixed reserved SS burst beginning part symbol and ending part symbol. For example, the first 2 symbols of each SS burst are reserved (the reserved symbols may be used as downlink control symbols or configured as mini slots (used for scheduling and transmission of data)), and the last 2 symbols (the reserved symbols are configured as guard interval and uplink control symbols or configured as mini slots); and the potential SS blocks start to be mapped continuously after the symbols reserved from the beginning of the SS burst are finished, and 13 SS blocks can be mapped continuously under the configuration of 4 continuous slots with 14 symbols.

For Type B SS block resources, SS blocks are mapped to Type B SS block resources only according to a specific sequence, and the specific sequence can be predefined by a system, namely a known rule between a network side and a terminal, or can be determined by the network side and notified to the terminal. In the above embodiment, the mapping rule is defined as mapping from front to back in sequence. Other mapping schemes are not excluded, and a mapping scheme from back to front is adopted as shown in fig. 11. For example, if the number of currently configured type B SS block resources is 8, the 8 SS blocks are mapped from back to front, and occupy SS blocks 25, 23, 21, 19, 17, 15, 13, 11, and 9. (the current type B SS block resource is defined as an odd numbered SS block).

Other rules apply, for example, defining a mapping backwards starting from a third SS block: the 8 SS blocks are mapped from back to front, occupying SS blocks 5, 7, 9, 11, 13, 15, 17.
