Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The field of technology to which the invention relates

[0001] The present invention relates to the field of communication technologies and, in particular, to a method for specifying a block of synchronization signals, a method for determining a block of synchronization signals, a network device, and a terminal device.

State of the art

[0002] The synchronization signal block is a signal structure defined in the New Radio (NR) standard and includes a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, SSS), and physical broadcast channel ((Physical Broadcast Channel, PBCH). The main functions of the PSS and SSS are to help the user equipment (User Equipment, UE) identify the cell and synchronize with the cell. The PBCH includes the most basic system information, for example, the number system frame or intra-frame synchronization information The UE cannot access the cell until the UE successfully receives the block of synchronization signals.

[0003] In order to support the NR multipath property, a Synchronization Signal Burst Set (SS burst set) is defined in NR. The burst sync set includes one or more blocks of sync signals. The maximum number L of sync blocks that can be included in a burst sync set varies across different frequency bands. In particular, when the frequency does not exceed 3 GHz, L=4. When the frequency falls between 3 GHz and 6 GHz, L=8. When the frequency falls between 6GHz and 52.6GHz, L=64.

[0004] In the actual transmission process, the number of actually transmitted sync blocks in the burst sync set is not always equal to L, and may be less than L. In a time slot in which a sync block is not transmitted, the base station may send other information or schedule the UE to complete the transfer. Thus, the base station must notify the UE of the actually transmitted sync blocks so that the UE successfully receives the sync blocks.

Description of Embodiments

[0055] Embodiments of the present invention are described in further detail with reference to the accompanying drawings.

[0056] FIG. 1 is a schematic diagram of a system used in one embodiment of the present invention. As shown in FIG. 1, system 100 may include a network device 102 and terminal devices 104, 106, 108, 110, 112, and 114. The network device and the terminal devices are connected wirelessly. It should be understood that in FIG. 1 is described simply by using an example in which the system includes one network device. However, this embodiment of the present invention is not limited thereto. For example, the system may alternatively include more network devices. Likewise, the system may also include more terminal devices. It should also be understood that a system may also be referred to as a network. This is not limited in this embodiment of the present invention.

[0057] Embodiments are described with reference to a terminal device in this specification. A terminal device may refer to a User Equipment (UE), an access terminal, a user equipment, a subscriber station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a portable device, having a wireless communication function, a computing device, another processing device connected to a wireless modem, a device in a vehicle, a wearable device, a terminal device in the future 5G network, a terminal device in the future Public Land Mobile Network (PLMN) ) or the like.

[0058] By way of example, and not limitation, in this embodiment of the present invention, the terminal device may also be a wearable device. A wearable device may also be referred to as a wearable smart device and is a general term for wearable devices such as glasses, gloves, watches, clothes and shoes that are designed using wearable technology in everyday wear smart designs. A wearable device is a portable device that can be worn directly on the body or embedded in the wearer's clothing or accessory. A wearable device is not just a hardware device, it is used to realize a powerful function through software support, data interaction, and cloud interaction. Universal smart wearable devices include full-featured and large-sized devices that can implement all or part of the functions independently of smartphones, such as smart watches or smart glasses, and devices that focus on only one type of application and must work with other devices, such as smartphones, in particular, various smart bracelets or smart jewelry for monitoring physical signs.

[0059] Embodiments are described with reference to the network device in this specification. The network device may be a device for communicating with a terminal device. The network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA) system, or may be a Node B (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system or may be an evolved NodeB (Evolved Node B, eNB or eNodeB) in a Long Term Evolution (LTE) system or may be a radio controller in a Cloud Radio Access Network (CRAN) scenario. Alternatively, the network device may be a relay node, an access point, an in-vehicle device, a wearable device, a network device in a future 5G network, a network device in a future evolved PLMN, or the like.

[0060] Further, in embodiments of the present invention, a network device provides service to a cell, and a terminal device communicates with the network device by using a transmission resource (eg, frequency domain resource or spectrum resource) used by the cell. The cell may be a cell corresponding to a network device (eg, a base station). The cell may belong to a macro base station or may belong to a base station corresponding to a small cell. The small cell herein may include: a Metro cell, a Micro cell, a Pico cell, a Femto cell, and the like. These small cells have the characteristics of low coverage and low transmission power, and are suitable for providing high-speed data services. Moreover, the cell may alternatively be a Hypercell.

[0061] According to the network device, which is used as an example, and not a limitation in this application, one network device can be divided into one centralized unit (Centralized Unit, CU) and a plurality of transmission reception points (Transmission Reception Point, TRP) / distributed blocks (Distributed Unit, DU). In other words, the Bandwidth Based Unit (BBU) of the network device is rebuilt into a DU and CU functionality. It should be noted that the shapes and numbers of centralized units and TRP/DUs are not limiting for embodiments of the present invention.

[0062] The CU can handle a high-level wireless protocol stack function such as a Radio Resource Control (RRC) layer or a Packet Data Convergence Protocol (PDCP) layer, and can even support some core network functions while immersed. to the access network. The access network is called the edge computing network and can meet the higher network latency requirements of the future communication network for new services such as video, online shopping and virtual/augmented reality.

[0063] The DU can basically process the physical layer function and the layer 2 function with higher requirements in real time. Considering the Radio Remote Unit (RRU) and the transmission resource of the DU, some of the physical layer functions of the DU can be moved to the RRU with the miniaturization of the RRU, and even more radically, the DU can be combined with the RRU.

[0064] The CU may be centrally deployed. Deployment of DU depends on the actual network environment. In the central urban area with high traffic density and short distance between stations, in a region with limited computer room resources, such as a university or a large-scale workplace, DU can also be deployed centrally. In an area with limited traffic and a relatively large distance between stations, such as a suburban area or a mountainous area, the DU can be deployed in a distributed manner.

[0065] In embodiments of the present invention, a Synchronization Signal block (SS block, SSB) is a signal structure defined in an NR wireless network. The block of synchronization signals will be briefly described below with reference to FIG. 2.

[0066] As shown in FIG. 2, each synchronization block includes a Primary Synchronization Signal (PSS) of one Orthogonal Frequency Division Multiplexing (OFDM) symbol, a Secondary Synchronization Signal (SSS) of one symbol, and a Physical Broadcast Channel (PBCH) of two symbols. The locations of the PSS, SSS, and PBCH in the sync block are shown in FIG. 2. The length of the PSS/SSS sequence is 127, occupying 127 subcarriers (Subcarrier, SC) in the frequency domain. PBCH occupies 288 subcarriers in the frequency domain.

[0067] It should be understood that in various embodiments of the present invention, a symbol and a subcarrier, respectively, represent a unit of granularity in the time and frequency domains of a time-frequency resource for signal transmission, and may have a value in a current communication system, or may have a value in a future system. connections. In addition, if the symbol and subcarrier names in the future communication system change, the symbol and subcarrier may also be changed to other names in the future communication system.

[0068] In various embodiments of the present invention, a group of synchronization signal blocks may also be referred to as a synchronization signal burst (Synchronization Signal Burst, SS burst). If the name of the sync block group in the future communication system is changed, then the sync block group can also be renamed in the future communication system.

[0069] In various embodiments of the present invention, the maximum number of synchronization signal block(s) that can be sent by a network device during a synchronization transmission period is a certain value. In other words, the maximum number of sync block(s) included in the burst sync set is determined. For brevity, the maximum number of sync block(s) included(s) in a burst sync set is denoted by L. For example, when the frequency falls between 6 GHz and 52.6 GHz, L=64. In an actual communication process, the number of sync blocks sent by the network device may be less than the maximum number, such as less than 64. The network device may transmit other data by using a time-frequency resource that is not used to transmit the sync block, or schedule to the terminal device was transmitting. When the number of block(s) of synchronization signals sent(s) by the network device is less than the maximum number, the network device must notify the terminal device of the block(s) of synchronization signals sent(s) by the network device so that the terminal device can receive the block(s) synchronization signals in a specific time-frequency resource.

[0070] In various embodiments of the present invention, the network device indicates the block(s) of synchronization signals sent(s) by the network device based on the group(s) of blocks of synchronization signals. The possible ways of grouping blocks of synchronization signals are briefly described below. For example, a burst sync block set includes a maximum number L of 64 sync blocks.

[0071] Option 1: 64 blocks of synchronization signals are divided into 16 groups of blocks of synchronization signals. Each sync block group includes four sync blocks. The sequence numbers of the 16 sync block groups are sequentially from 0 to 15 and can be represented by using 4-bit information. The sequence numbers of the four sync blocks included in each sync block group are sequentially from 0 to 3, and can be represented by using 2-bit information.

[0072] Option 2: The 64 sync blocks are divided into eight groups of sync blocks. Each sync block group includes eight sync blocks. The sequence numbers of the eight sync block groups are sequentially from 0 to 7 and can be represented by using 3-bit information. The sequence numbers of the eight sync blocks included in each sync block group are sequentially from 0 to 7, and can be represented by using 3-bit information.

[0073] Option 3: The 64 sync blocks are divided into four groups of sync blocks. Each sync block group includes 16 sync blocks. The sequence numbers of the four groups of synchronization signal blocks are sequentially from 0 to 3 and can be represented by using 2-bit information. The sequence numbers of the 16 sync blocks included in each sync block group are sequentially from 0 to 15, and can be represented by using 4-bit information.

[0074] It should be noted that the above grouping options are examples. Based on the above grouping principle, there may be another grouping option. For example, 64 blocks of synchronization signals are divided into 32 groups. In addition, the sequence number of each sync block in the burst sync block set can be determined based on the sequence number of the sync block group to which the sync signal block belongs and the sequence number of the sync signal block in the sync block group. By using the above grouping option 2 as an example, the sequence number of the sync block group 1 can be represented as 001, and the sequence number of the sync signal block 2 in the sync block group 1 can be represented as 010. In this case, the sequence number of the sync block 2 can be represented as 010. in sync block group 1 is 001010 (the binary value of the sync block sequence number is used as the higher order, and the binary value of the sync block sequence number is used as the lower order) in the sync burst. In other words, the sequence number of the sync block 2 in the sync block group 1 is 10 in the burst sync set. In another example, the sequence number of the sync signal group 7 can be represented as 111, and the sequence number of the sync signal block 2 in the sync signal block group 7 can be represented as 010. In this case, the sequence number of the sync signal block 2 in the sync signal block group 7 is 111010 in burst clock set. In other words, the sequence number of the sync block 2 in the sync block group 1 is 58 in the burst sync set. In other words, the higher order in the binary value of the sequence number of each sync block in the burst sync block set is the binary value of the sequence number of the sync block group to which the sync block belongs, and the lower order in the binary value of the sequence number of each sync block in a sync block burst set, is the binary value of the sync block sequence number in the sync block group.

[0075] In various embodiments of the present invention, the locations of the block of synchronization signals sent by the network device in the groups of blocks of synchronization signals sent by the network device are the same. However, the fact that the locations are the same may also mean that the sync block sequence numbers in the sync block groups sent by the network device are the same. By using the above grouping option 3 as an example, the sync block sequence numbers sent by the network device in sync block group 0 are 0, 1, 2, and 3, and the sync block sequence numbers sent by the network device in signal block group 1 sync are 0, 1, 2, and 3. In this case, the sync block locations sent by the network device in the two sync block groups are the same. In other words, the sync blocks sent by the network device in each of the two sync block groups are the first four sync blocks in the sent sync block group. In another example, the sync block sequence numbers sent by the network device in sync block group 0 are 0, 2, 4, and 6, and the sync block sequence numbers sent by the network device in sync block group 1 are 0, 2, 4 and 6. In this case, the locations of the sync block sent by the network device in the two sync block groups are also the same. It will be understood that the sequence numbers of the sync blocks sent by the network device in each sync block group sent by the network device may be sequential or non-sequential.

[0076] The following describes in detail the method for specifying a block of synchronization signals provided in the embodiments of the present invention with reference to the accompanying drawings.

[0077] FIG. 3 is a flowchart of a method 300 for specifying a block of synchronization signals according to one embodiment of the present invention. The network device in Fig. 3 may be the network device 102 in the system shown in FIG. 1. The terminal device may be terminal devices 104, 106, 108, 110, 112, and 114 in the system shown in FIG. 1. In a specific implementation process, the number of network devices and terminal devices may not be limited to examples in this embodiment and another embodiment. No further details are given below.

[0078] 310. The network device generates a synchronization signal block indication message, wherein the synchronization signal block indication message includes synchronization signal block group indication information and synchronization signal block indication information, the synchronization signal block group indication information is used to indicate the synchronization signal block group sent by the network device, the sync block indication information is used to indicate the sync block sent by the network device in each sync block group sent by the network device, and the location of the sync block sent by the network device in the sync block groups sent by the network device, are the same.

[0079] In one exemplary embodiment, the sync block group indication information includes quantitative information and configuration information of the sync block group sent by the network device. The quantitative information is used to indicate the number m of the group(s) of synchronization signal blocks sent(s) by the network device. The configuration information is used to indicate whether the sync block group(s) sent(s) by the network device is the first(s) m sync block group(s) or the last(last) m sync block group(s) of all groups of blocks of synchronization signals. Accordingly, the synchronization signal block designation information may be bitmap information. The bitmap information is used to indicate a sync block sent by the network device in each sync block group sent by the network device. In a specific implementation process, since the locations of the sync block sent by the network device in the sync block groups sent by the network device are the same, the network device can indicate the sync block group sent by the network device by using the quantitative information and configuration information of the block group sync signal block and indicate, by using the sync block bitmap information, the sync signal block sent by the network device in each sync block group sent by the network device, thereby indicating to the terminal device all (all) of the sync block(s) sent ( sent) by the network device. By using the grouping option 2 described above as an example, the sync block group quantity information may be 3-bit information, for example, may be 100, and an example of sync block group configuration information may be described by using Table 1, and may be The 1-bit information may be 0, for example. In this case, the number of sync block groups sent by the network device is four, and the four sync block groups are the first four sync block groups, namely groups 0, 1, 2 and 3 sync blocks, from all sync block groups. Accordingly, the sync block bitmap information may be a bit sequence. The bit sequence has a length equal to the number of sync blocks in each sync block group, and each bit in the bit sequence corresponds to one sync block. If the bit value is 1, then this means that the corresponding block of synchronization signals is being sent. If the bit value is 0, it means that the corresponding block of synchronization signals is not sent. Specifically, the sync block bitmap information may be an 8-bit sequence, for example, may be 10100000. In this case, the sync blocks sent by the network device in each sync block group sent by the network device is the first sync block, and the third synchronization signal block, namely the synchronization signal block 0 and the synchronization signal block 2. It is understood that when the quantity information and configuration information of the sync block group sent by the network device received by the terminal device are 100 and 0, respectively, and the sync block bitmap information is 10100000, the terminal device can determine that the sync block groups, sent by the network device are the first four sync block groups, namely sync block groups 0, 1, 2, and 3 of all sync block groups. The sync blocks sent by the network device in each sync block group sent by the network device are the first sync block and the third sync block, namely sync block 0 and sync block 2. It should be noted that the number of synchronization block group(s) may not have a one-to-one correspondence with the binary value corresponding to the bit information. For example, in the above example, when the 3-bit information is 000, the corresponding number of sync block groups may be eight. In other words, all groups of sync blocks are sent. The correspondence between the number of synchronization block group(s) and the binary value corresponding to the bit information can be determined depending on the actual need. Here it is not limited.

[0080] It should be noted that in this case, when different synchronization signal block groupings are used, the network device overhead for indicating the synchronization signal block(s) sent(s) by the network device is different. Details in the following. The grouping options are the same as the grouping options described above.

[0081] Case 1: A network device requires 4 bits to indicate quantitative information, 1 bit is required to indicate configuration information, and 4 bits are required to indicate bitmap information. With this grouping option, the network device overhead for specifying blocks of synchronization signals sent by the network device is 9 bits.

[0082] Case 2: A network device requires 3 bits to indicate quantitative information, 1 bit is required to indicate configuration information, and 8 bits are required to indicate bitmap information. With this grouping option, the network device overhead for specifying blocks of synchronization signals sent by the network device is 12 bits.

[0083] Option 3: The network device requires 2 bits to indicate quantitative information, 1 bit is required to indicate configuration information, and 16 bits are required to indicate bitmap information. With this grouping option, the network device overhead for specifying blocks of synchronization signals sent by the network device is 19 bits.

Table 1 0 Sending the first m groups of sync signals one Sending the last m groups of sync signals

[0084] Optionally, the synchronization signal block group indication information includes quantitative information of the synchronization signal block group sent by the network device. Quantity information is used to indicate the group of blocks of synchronization signals sent by the network device. In this case, the configuration rule of the sync block group sent by the network device is predefined. For example, the configuration rule may be predefined in the communication protocol. For example, the rule may be that the sync block group(s) sent(s) by the network device is the first(s) m sync block group(s), or the sync block group(s) sent(s) ) by the network device is the last m sync block group(s), where m is the number of sync block group(s) sent by the network device. When the value of m is determined, the group(s) of synchronization signal blocks sent(s) by the network device can be determined.

[0085] In one exemplary embodiment, the sync block group indication information includes quantity information and configuration information of the sync block group sent by the network device. The quantitative information is used to indicate the number m of the group(s) of synchronization signal blocks sent(s) by the network device. The configuration information is used to indicate whether the sync block group(s) sent by the network device is the first (first) m sync block group(s) or the last (last) m sync block group(s) of of the entire (all) group (s) of blocks of synchronization signals. Accordingly, the timing signal block designation information includes quantity information and configuration information of the synchronization signal block sent by the network device. Quantity information is used to indicate the number n of block(s) of synchronization signals sent(s) by the network device in each group of blocks of synchronization signals sent by the network device. The configuration information is used to indicate whether the sync block(s) sent by the network device in each sync block group(s) sent by the network device is(are) the first(s) n sync block(s) or the last ( last) n sync block(s) in the sync block group. Unlike the above first possible embodiment, in this case, the block(s) of synchronization signals sent(s) by the network device in each block group of synchronization signals sent by the network device is(are) indicated by using quantitative information and configuration information. By using the grouping option 2 described above as an example, the sync block group quantity information may be 3-bit information, for example, may be 100, and an example of sync block group configuration information may be described by using Table 1, and may be The 1-bit information, for example, may be 1. In this case, the sync signal block quantity information may be 3-bit information, for example, may be 010, and an example of the sync signal block configuration information may be described by using Table 2, and may be 1 -bit information, for example, may be 0. In this case, the number of sync block groups sent by the network device is four, and the four sync block groups are the last four sync block groups, namely group 4, 5, 6, and 7 blocks of synchronization signals, from all groups pp synchronization signal blocks. The number of sync block sent by the network devices in each sync block group sent by the network device is two, and the two sync blocks are the first two sync blocks, namely sync block 0 and sync block 1, in the group blocks of synchronization signals. It is understood that when the quantity information and configuration information of the synchronization signal block groups sent by the network device received by the terminal device are 100 and 1, respectively, and the quantity information and configuration information of the synchronization signal block sent by the network device are 010 and 0, respectively, the terminal device can determine that the sync block groups sent by the network device are the last four sync block groups, namely, sync block groups 4, 5, 6, and 7 of all sync block groups, the number of sync blocks sent by the network device in each sync block group sent by the network device is two, and the two sync blocks are the first two sync blocks, namely sync block 0 and sync block 1, in the group ne blocks of synchronization signals. It should be noted that the number of the sync signal block group may not have a one-to-one correspondence with the binary value corresponding to the bit information. For example, in the above example, when the 3-bit information is 000, the corresponding number of sync block groups may be eight. In other words, all groups of sync blocks are sent. The correspondence between the number of synchronization block group(s) and the binary value corresponding to the bit information can be determined depending on the actual need. Here it is not limited. Similarly, the number of blocks of synchronization signals may not have a one-to-one correspondence to the binary value corresponding to the bit information. For example, in the above example, when the 3-bit information is 000, the corresponding number of synchronization signal blocks may be eight. In other words, all sync blocks in the sync block groups sent by the network device are sent. The correspondence between the number of block(s) of synchronization signals and the binary value corresponding to the bit information can also be determined depending on the actual need. Here it is not limited.

[0086] It should be noted that in this case, when different synchronization signal block groupings are used, the network device overhead for indicating the synchronization signal block sent by the network device is different. Details in the following. The grouping methods are the same as the grouping methods described above.

[0087] Case 1: 4 bits are required to indicate the quantitative information of the synchronization signal block group sent by the network device, the network device, and 1 bit is required to indicate the configuration information. In each sync block group sent by the network device, 2 bits are required to indicate quantitative sync block information sent by the network device, and 1 bit is required to indicate configuration information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 8 bits.

[0088] Option 2: 3 bits are required to indicate the quantitative information of the synchronization signal block group sent by the network device, and 1 bit is required to indicate the configuration information. In each sync block group sent by the network device, 3 bits are required to indicate the quantitative information of the sync signal block sent by the network device, and 1 bit is required to indicate the configuration information. With this grouping option, the network device overhead for indicating the block of synchronization signals sent by the network device is 8 bits.

[0089] Option 3: It takes 2 bits to indicate the quantitative information of the synchronization signal block group sent by the network device, and 1 bit to indicate the configuration information. In each sync block group sent by the network device, 4 bits are required to indicate the quantitative information of the sync signal block sent by the network device, and 1 bit is required to indicate the configuration information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 8 bits.

table 2 0 Sending the first n blocks of sync signals one Sending the last n blocks of sync signals

[0090] In one exemplary embodiment, the synchronization signal block group indication information is bitmap information. The sync block group bitmap information is used to indicate the sync block group sent by the network device. Accordingly, the timing signal block designation information may also be bitmap information. The sync block bitmap information is used to indicate the sync block sent by the network device in each sync block group sent by the network group. By using the grouping option 2 described above as an example, the bitmap information of the signal sync block group can be a bit sequence. The bit sequence has a length equal to the number of sync block group(s), and each bit in the bit sequence corresponds to one sync block group. If the value of the bit is 1, then this indicates that the corresponding group of synchronization signal blocks is being sent. If the bit value is 0, this indicates that the corresponding sync block group is not sent. Specifically, the sync block group bitmap information may be an 8-bit sequence, for example, may be 10100000. In this case, the sync block groups sent by the network device are the first sync block group and the third sync block group, namely sync block group 0 and sync block group 2. Like the sync block group bitmap information, the sync block bitmap information may also be an 8-bit sequence, for example, may be 110000000. In this case, the sync block sent by the network devices in each sync block group sent by the network device, is the first block of synchronization signals and the second block of synchronization signals, namely block 0 of the synchronization signals and block 1 of the synchronization signals. It can be understood that when the bitmap information of the sync block groups sent by the network device is 10100000 and the bitmap information of the sync block groups sent by the network device is 11000000, the terminal can determine that the sync block groups sent by the network device , are the first sync block group and the third sync block group, namely, sync block group 0 and sync block group 2, and the sync blocks sent by the network device in each sync block group sent by the network device are a first block of synchronization signals and a second block of synchronization signals, namely block 0 of the synchronization signals and block 1 of the synchronization signals.

[0091] It should be noted that in this case, when using different options for grouping blocks of synchronization signals, the service data of the network device for indicating the block of signals sent by the network device may be different. The details are as follows. The grouping options are the same as the grouping options described above.

[0092] Case 1: The network device requires 16 bits to indicate the sync block group bitmap information, and 4 bits are required to indicate the sync block bitmap information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 20 bits.

[0093] Case 2: The network device requires 8 bits to indicate bitmap information of the sync signal block group, and 8 bits are required to indicate the bitmap information of the sync signal blocks. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 16 bits.

[0094] Case 3: The network device requires 4 bits to indicate the sync block group bitmap information, and 16 bits are required to indicate the sync block bitmap information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 20 bits.

[0095] In one exemplary embodiment, the synchronization signal block group indication information is bitmap information. The sync block group bitmap information is used to indicate the sync block group sent by the network device. Accordingly, the timing signal block designation information includes quantity information and configuration information of the synchronization signal block sent by the network device. Quantity information is used to indicate the number n of block(s) of synchronization signals sent(s) by the network device in each group of blocks of synchronization signals sent by the network device. The configuration information is used to indicate whether the sync block(s) sent by the network device in each sync block group sent by the network device is(are) the first(s) n sync block(s) or the last ( last) n sync block(s) in the sync block group. By using the grouping option 2 described above as an example, the sync block group bitmap information can be a bit sequence. The bit sequence has a length equal to the number of sync block group(s), and each bit in the bit sequence corresponds to one sync block group. If the bit value is 1, it means that the corresponding group of blocks of synchronization signals is being sent. If the bit value is 0, then this indicates that the corresponding sync block group is not sent. Specifically, the sync block group bitmap information may be an 8-bit sequence, for example, may be 11000000. In this case, the sync signal block quantity information sent by the network device may be 3-bit information, for example, may be 010, and an example of the sync block configuration information may be described by using Table 2, and may be 1-bit information, for example, may be 1. In this case, the sync block groups sent by the network device are the first sync block group and the second sync block group sync blocks, namely sync block group 0 and sync block group 1. The number of sync blocks sent by the network device in each sync block group sent by the network device is two, and the two sync blocks are the last two sync blocks, namely sync block 6 and sync block 7, in the group blocks of synchronization signals. It is understood that when the sync block group bitmap information received by the terminal device is 11000000, the sync block quantity information is 010, and the sync block configuration information is 1, the terminal device can determine that the sync block groups sent by the network device are the first sync block group and the second sync block group, namely sync block group 0 and sync block group 1, the number of sync blocks sent by the network device in each sync block group sent by the network device is two , and the two sync blocks are the last two sync blocks, namely the sync block 6 and the sync block 7, in the sync block group. It should be noted that the number of block(s) of synchronization signals may not have a one-to-one correspondence to the binary value corresponding to the bit information. For example, in the above example, when the 3-bit information is 000, the corresponding number of synchronization signal blocks may be eight. In other words, all sync blocks in the sync block groups sent by the network device are sent. The correspondence between the number of blocks of synchronization signals and the binary value corresponding to the bit information can be determined depending on the actual need. Here it is not limited.

[0096] It should be noted that in this case, when different synchronization signal block groupings are used, the network device overhead for indicating the synchronization signal block sent by the network device may be different. Details in the following. The grouping options are the same as the grouping options described above.

[0097] Option 1: It takes 16 bits to indicate the bitmap information of the sync block group(s) by the network device, and 2 bits are required to indicate the amount of sync block information sent by the network device in each sync block group sent by the network device , and 1 bit is required to indicate the configuration information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network device is 19 bits.

[0098] Option 2: It takes 8 bits to indicate the bitmap information of the sync block group(s) by the network device, 3 bits are required to indicate the quantitative information of the sync signal block sent by the network device in each sync block group sent by the network device, and 1 bit is required to indicate the configuration information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network devices is 12 bits.

[0099] Option 3: It takes 4 bits to indicate the bitmap information of the sync block group(s) by the network device, 4 bits are required to indicate the quantity information of the sync signal block sent by the network device in each sync block group sent by the network device, and 1 bit is required to indicate the configuration information. With this grouping option, the service data of the network device to indicate the block of synchronization signals sent by the network devices is 9 bits.

[0100] Optionally, the sync block indication information includes timing signal block quantity information sent by the network device. Quantity information is used to indicate a block of synchronization signals sent by the network device in each group of blocks of synchronization signals sent by the network device. In this case, the sync block configuration rule is predefined. For example, the configuration rule may be predefined in the communication protocol. For example, the rule may be that the sync block(s) sent by the network device in each sync block group sent by the network device is (are) the first n sync block(s) or the last (last) n sync block(s) in the sync block group, where n is the number of sync block(s) sent by the network device in each sync block group sent by the network device. When the value of n is determined, the block(s) of synchronization signals sent(s) by the network device in each group of blocks of synchronization signals sent by the network device can be determined.

[0101] 320. The network device sends a synchronization block indication message.

[0102] The network device sends a synchronization block indication message. The synchronization signal block designation message includes synchronization signal block designation information and synchronization signal block designation information.

[0103] In one exemplary embodiment, the sync signal block group indication information is carried by using the MIB, and the sync signal block indication information is carried by using the RMSI. By using the above grouping option 2 as an example, when the sync signal block group designation information is bitmap information, and the sync signal block designation information is also bitmap information, 8-bit sync block group designation information is transferred by using MIB and 8- bit information of indication of blocks of synchronization signals is transferred by using RMSI.

[0104] Optionally, the sync signal block group indication information is carried by using the RMSI, and the sync signal block indication information is carried by using the MIB.

[0105] By using the above grouping option 2 as an example, when the sync signal block group designation information is bitmap information, and the sync signal block designation information is quantity information and configuration information, 8-bit sync signal block group designation information is transferred by using The RMSI and 4-bit sync block indication information is carried by using the MIB.

[0106] Optionally, synchronization signal block group indication information and synchronization signal block indication information are transferred by using the MIB.

[0107] Optionally, synchronization signal block group indication information and synchronization signal block indication information are transferred by using RMSI.

[0108] 330. The terminal device determines, based on the sync block indication message, a sync block group sent by the network device and a sync block sent by the network device in each sync block group sent by the network device.

[0109] After receiving the sync block indication message sent by the network device, the terminal device, based on the sync block indication message, determines the sync block group sent by the network device and the sync signal block sent by the network device in each sync block group sent by the network device. network device. In a particular implementation process, the terminal device can specifically, by parsing the sync block indication message, determine the sync block group sent by the network device and the sync block sent by the network device in each sync block group sent by the network device. The specific implementation process has already been described in detail at block 310. Again, the details are not described here.

[0110] It can be seen that the network device, through the sync block indication message, indicates the sync block group sent by the network device and the sync block sent by the network device in each sync block group sent by the network device. Since the locations of the sync block sent by the network device in the sync block groups sent by the network device are the same, the terminal device can determine, based on the sync block indication message, the entire sync block(s) sent(s) network device to successfully receive block(s) of synchronization signals.
