[0018] Mobile communication continues the development rule of a generation of technology every ten years, and has experienced the development of the first generation mobile communication standard (1th Generation Mobile Communication Technology, 1G), the second generation mobile communication standard (2th Generation Mobile Communication Technology, 2G), the third generation mobile communication standard (3th Generation Mobile Communication Technology, 3G), the fourth generation mobile communication standard (4th Generation Mobile Communication Technology, 4G), and the fifth generation mobile communication standard (5th Generation Mobile Communication Technology, 5G). Each time the intergenerational leap and each time the technological progress greatly promotes the industrial upgrading and the economic and social development. From 1G to 2G, the transition from analog communication to digital communication is realized, and mobile communication enters millions of households; from 2G to 3G, 4G and 5G, the transformation from voice service to data service is realized, the transmission rate is hundreds of times higher, and the popularization and prosperity of mobile Internet applications are promoted. With the rapid development of mobile Internet, new services, new businesses, new technologies and new equipment are emerging, and 5G mobile communication system is difficult to meet the needs of future flexible and diverse businesses, and the next generation mobile communication system, i.e. the sixth generation mobile communication standard (6th Generation Mobile Communication Technology, 6G), is urgently needed.

[0019] 6G, i.e. the sixth generation mobile communication standard, is a conceptual wireless network mobile communication technology, also known as the sixth generation mobile communication technology. 6G will support higher speed, the number of bits corresponding to a transmission block will be larger, a transmission block will include more code blocks, and the ACK / NACK flexibility of the downlink transmission block and the corresponding code block will have higher requirements to obtain higher transmission efficiency.

[0020] In 5G New Radio (5G NR), the Synchronization Signal Block (SSB) beam index is used to identify and indicate a specific SSB beam, which is crucial for beam management and beam training processes. The definition of SSB beam index allows User Equipment (UE) and the next generation NodeB (gNB) to identify the best beam pair, thereby optimizing the reception and transmission of signals.

[0021] Time-frequency resource of SSB: SSB beam index is related to the allocation of SSB on time-frequency resource, including OFDM symbol index and subcarrier spacing (SCS) of SSB.

[0022] Transmission mode of SSB: 5G NR defines at least five different SSB transmission modes (Case A, B, C, D, E), each with different time slot and symbol index of SSB, which affects the definition of beam index.

[0023] Periodicity of SSB: The transmission periodicity of SSB (e.g. 5ms, 10ms, 20ms, 40ms, 80ms, 160ms) also affects the definition of beam index, as the number of SSB transmissions and time interval will be different under different periodicity. SSB index is transmitted according to the standard defined position within a half frame (5ms), which is periodically transmitted according to the above-mentioned period.

[0024] Beamforming: SSB beam index is related to the beamforming technology of base station antenna array, and the base station generates a beam with a certain directivity by adjusting the phase and amplitude of antenna elements.

[0025] Beam training process: In the beam training process, the UE measures the performance of different SSB beams and reports these measurements to the base station, and the base station determines the best beam index according to these reports.

[0026] Beam management strategy: Network operators may define specific beam management strategies according to the specific situation and optimization target of the network, which will affect the selection and allocation of SSB beam index.

[0027] SSB is a key signal for cell search, synchronization and beam management. The following are the specific definitions of the five SSB transmission modes (Case A, B, C, D, E):

[0028] Case A:

[0029] Applicable scenario: Applicable to subcarrier spacing (SCS) of 15KHz.

[0030] Time domain distribution: The orthogonal frequency division multiplexing (OFDM) symbol index of SSB on a 5ms half frame is {2, 8} + 14n, where n is the time slot number.

[0031] Frequency domain distribution: SSB can be configured at any location of the carrier, not necessarily at the center frequency.

[0032] Maximal transmission number: n = 0,1, maximal transmission number is 4 when Fc≤3GHz; n = 0,1,2,3, maximal transmission number is 8 when 3GHz < Fc≤6GHz.

[0033] Feature: SSB is discontinuous in time domain, which can be used for downlink control channel information.

[0034] Case B:

[0035] Applicable scenario: applicable to SCS of 30KHz.

[0036] Time domain distribution: SSB is in OFDM symbol index {4,8,16,20}+28n on 5ms half frame.

[0037] Maximal transmission number: n = 0, SSB occupies 2 slots, maximal transmission number is 4 when Fc≤3GHz; n = 0,1, SSB occupies 4 slots, maximal transmission number is 8 when 3GHz < Fc≤6GHz.

[0038] Feature: SSB is asymmetrically distributed in different slots to ensure coexistence with 15kHz subcarrier control / data channel.

[0039] Case C:

[0040] Applicable scenario: also applicable to SCS of 30KHz, but slightly different from Case B.

[0041] Time domain distribution: SSB is in OFDM symbol index {2,8}+14n on 5ms half frame.

[0042] Maximal transmission number: similar to Case B, but #6, #7 slots are not mapped to ensure coexistence with 60KHz SCS configuration.

[0043] Case D:

[0044] Applicable scenario: applicable to SCS of 120KHz, mainly used in high frequency band (Frequency Range 2, FR2).

[0045] Time domain distribution: SSB is in OFDM symbol index {4,8,16,20}+28n on 5ms half frame.

[0046] Maximal transmission number: n is an integer set from 0 to 18, excluding 4, 9, 14, maximal transmission number is 64 when Fc>6GHz.

[0047] Case E:

[0048] Applicable scenario: applicable to SCS of 240KHz, mainly used in FR2.

[0049] Time-domain distribution: SSB is in OFDM symbol indices {8, 12, 16, 20, 32, 36, 40, 44} + 56n over a 5ms half-frame.

[0050] Maximum number of transmissions: When Fc>6GHz, n ranges from 0 to 8, and the maximum number of transmissions is 64.

[0051] These patterns allow 5G NR networks to flexibly configure SSB transmissions based on different frequency ranges, subcarrier spacings, and center frequencies, to optimize the performance of cell search, synchronization, and beam management.

[0052] SSB index is used to identify a specific SSB beam in 5G NR. The maximum value of SSB index depends on the frequency band, subcarrier spacing (SCS), and transmission pattern (Case A, B, C, D, E) of 5G NR.

[0053] For Sub-3 GHz band: In the Sub-3 GHz band, i.e., frequencies below 3 GHz, a maximum of 4 SSB Blocks can be supported.

[0054] For Sub-6 GHz band: In the Sub-6 GHz band, i.e., frequencies between 2.4 GHz and 6 GHz, a maximum of 8 SSB Blocks can be supported.

[0055] For mmWave band: In the mmWave band, i.e., frequencies above 6 GHz, more SSB Blocks can be supported, up to a maximum of 64 SSB Blocks.

[0056] The specific range of SSB index values depends on the configuration of the network operator and the capabilities of the UE (User Equipment). The network can flexibly configure the values of SSB index based on different beam design and optimization requirements.

[0057] In the future network, distributed deployment can be adopted, each distributed node has a corresponding SSB index, the SSB indexes between different distributed nodes are independent of each other, but there is a correlation between the distributed nodes with adjacent deployment positions, including: there is an adjacent relationship (or there is a switching correlation), and the distributed nodes that are not adjacent are independent of each other, and for the distributed nodes that are far apart, not only are they independent of each other, but there is a repulsion relationship between them. When a terminal, such as a user equipment, moves, the terminal can switch between the SSB indexes (or beam indexes) corresponding to adjacent distributed nodes. However, due to the different positions, the terminal will not directly jump to the distributed nodes that are not adjacent (or the distributed nodes that are far apart / the distributed nodes with completely different position directions). Therefore, the terminal can perform SSB index detection or beam measurement or beam switching based on the correlation during movement, thereby reducing the search power consumption of the terminal. At the same time, for the distributed nodes without terminal residence, the network can also not send SSB or send SSB with a large period in the distributed nodes, thereby reducing the power consumption of the network for sending SSB and achieving network energy saving.

[0058] In the 5G NR system, these SSB indexes are independent and have no correlation, and the terminal cannot obtain the correlation between the SSB indexes, so it cannot reduce the SSB detection power consumption, and the network cannot dynamically close some SSB indexes to achieve network energy saving. Therefore, a method for representing the correlation between SSB indexes or synchronization channel indexes or beam indexes is needed to reduce the power consumption of the terminal for detecting SSB or synchronization channel in the idle or inactive state, and the power consumption of the network, so that the network can dynamically close or open SSB.

[0059] In this application, the synchronization signal block SSB is only a name defined for convenience of description. The SSB mentioned here can be applied to 5G NR, 6G system, and other systems. It represents a signal and / or channel (such as: SSB only includes a synchronization signal, or SSB only includes a physical broadcast channel, or SSB includes a synchronization signal and a physical broadcast channel, or SSB includes a measurement signal) detected by the terminal in the idle or inactive state, without limiting the specific form, specific structure, or name.

[0060] In addition, in a large-scale distributed Multiple Input Multiple Output (MIMO) scenario, antennas adopt a distributed architecture, and there is a correlation between beams generated by adjacent distributed antennas. Therefore, the same problems exist in the distributed MIMO scenario, and there is a need to indicate the correlation between beam indexes, especially for signals and / or channels transmitted in an idle or inactive state. The above correlation is different from the Quasi-Colocation (QCL) relationship in MIMO, which means that the beams or ports are the same or similar, and the premise of the correlation is different. Therefore, the adjacent relationship mentioned in the present application is not a QCL relationship.

[0061] The above correlation is different from the relationship between same-frequency cells or different-frequency cells. The relationship between same-frequency cells or different-frequency cells is for the relationship between different cells, and the present application is for the relationship between different SSB indexes under the same cell (or the relationship between different beam indexes under the same cell).

[0062] In the present application, the adjacent relationship can represent adjacency or correlation, which means that there is a connection, but the type or manner of the connection is not limited. The terminal measures or detects together, which is equivalent to defining a set range of terminal detection or measurement.

[0063] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0064] The steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer-executable instructions. Moreover, although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0065] In the present application, the terms "first", "second", etc. are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0066] Figure 1 An information transmission schematic diagram is provided for the embodiments of the present application. As shown in Figure 1 The first communication node 1 and the second communication node 2 are communicatively interconnected, and information interaction is performed to realize information transmission for synchronization signal block indexes. When the first communication node 1 is a terminal, the second communication node 2 is a base station.

[0067] In one exemplary embodiment, Figure 2A flowchart of a configuration method provided by an embodiment of the present application is shown. The method can be applied to transmitting the association relationship between synchronization signal block indexes to achieve the detection of synchronization signal blocks. The method can be performed by a first communication node provided by the present application, which covers any type of wireless user equipment.

[0068] As shown in Figure 2 , the present application provides an information transmission method, which includes S110-S120.

[0069] S110, obtain the association relationship between synchronization signal block indexes, which indicates the synchronization signal block indexes having the association relationship in a cell.

[0070] The synchronization signal block index can be understood as information indicating the synchronization signal block, and can also be referred to as SSB index or beam index. The present application represents the association relationship between the synchronization signal block indexes, which represents the association relationship between the synchronization signal blocks. The association relationship can be understood as an adjacent relationship or a switching association.

[0071] In one embodiment, the operation can obtain the association relationship between the synchronization signal block indexes transmitted by the second communication node, so as to detect the synchronization signal blocks in the cell based on the association relationship between the synchronization signal block indexes.

[0072] The synchronization signal block SSB is transmitted according to a predefined position in a time window, and the SSB in the time window is periodically transmitted; the time window can be 5ms or 10ms, and different time window sizes are defined for different frequency points or frequency bands (such as FR1, FR2, FR3, etc.), such as 5ms for FR1, 2ms for FR2, and 1ms for FR3, or 5ms for FR1 and FR2, and 1ms or 2ms for FR3, etc.; the period can be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.; assuming that the SSB index is numbered from 0, the total number of SSB indexes is m, the SSB index number is 0, 1, 2,..., n-1; the SSB indexes in the time window are sequentially numbered, and the adjacent relationship between the SSB indexes can be predefined and indicated by signaling.

[0073] In one example, the synchronization signal block indexes having the association relationship are located in the same regional association set, or the synchronization signal block indexes having the association relationship are located in the same spatial association set, or the synchronization signal block indexes having the association relationship are located in the same direction, or the synchronization signal block indexes having the association relationship have a specific binding relationship, or the synchronization signal block indexes having the association relationship are located in the same measurement association set, or the synchronization signal block indexes having the association relationship are located in the same synchronization association set.

[0074] The region-associated set can be understood as a set of synchronization signal blocks in a region (e.g., a cell, a region composed of multiple cells, a micro cell in a cell, or an associated transmission node). The spatial-associated set can be understood as a set of synchronization signal blocks in a divided space, such as a set of synchronization signal blocks in a divided space based on a beam direction or a set of synchronization signal blocks in a divided space based on a multi-Transmission Reception Point (multi-TRP). The measurement-associated set can be understood as a set of synchronization signal blocks to be measured. The synchronization-associated set can be understood as a set of synchronization signal blocks having an uplink synchronization relationship (e.g., a synchronization signal block number that can be used for uplink synchronization, or a synchronization signal block corresponding to a same uplink carrier set, or a synchronization signal block corresponding to a same uplink carrier, or a synchronization signal block corresponding to a same uplink cell, or a synchronization signal block corresponding to a same uplink cell set) or a downlink synchronization relationship (e.g., a synchronization signal block number that can be used for downlink synchronization, or a synchronization signal block corresponding to a same downlink carrier, or a synchronization signal block corresponding to a same downlink carrier set, or a synchronization signal block corresponding to a same downlink cell, or a synchronization signal block corresponding to a same downlink cell set).

[0075] The synchronization signal block indexes having the association relationship can be located in any relevant association set in a region, such as a region-associated set, a spatial-associated set, a measurement-associated set, and a synchronization-associated set. The synchronization signal block indexes having the association relationship can also be located in a same region, in a same direction, or have a specific binding relationship.

[0076] In an example, the association relationship between the synchronization signal block indexes includes:

[0077] The synchronization signal block group indexes have a first association relationship, and the first association relationship between the synchronization signal block group indexes includes at least one of the following: an association relationship between adjacent synchronization signal block group indexes, an association relationship between synchronization signal block group indexes configured by first signaling, or an association relationship between synchronization signal group indexes set at intervals.

[0078] In the region, a plurality of synchronization signal block groups can be included, and each synchronization signal block group corresponds to a synchronization signal block group index. In a synchronization signal block group, a plurality of synchronization signal blocks can be included, and each synchronization signal block corresponds to a synchronization signal block index. The synchronization signal block groups in a same region can have an association relationship, and the synchronization signal block group indexes have an association relationship accordingly. The synchronization signal blocks in a same synchronization signal block group can also have an association relationship, and the synchronization signal block indexes have an association relationship accordingly.

[0079] The first association relationship can be understood as an association relationship between synchronization signal block group indexes corresponding to a synchronization signal block group. The first signaling can be understood as indication signaling configured by the second communication node to generate, and the first signaling indicates that there is a synchronization signal block group index with an association relationship in the cell. For example, the first signaling includes: a synchronization signal block group index associated with a synchronization signal block group index; or, the first signaling includes: an association set index corresponding to a synchronization signal block group index; the synchronization signal block group index associated with the synchronization signal block group index (the synchronization signal block group index corresponding to the association set index) can be indicated in the form of a bitmap, each bit corresponding to a synchronization signal block group index, or in the form of a starting synchronization signal block group index and a number of consecutive synchronization signal block group indexes, or in the form of a list of synchronization signal block group indexes (for example, index #d0, index #d1, etc.).

[0080] In one embodiment, the association relationship between adjacent synchronization signal block group indexes can be understood as an association relationship determined based on the adjacent relationship between the synchronization signal block group indexes, and in this embodiment, the adjacent synchronization signal block group indexes have an association relationship.

[0081] The synchronization signal block indexes are divided into groups, the SSB groups have an association relationship, and the SSB indexes within a group can be independent or have a specific relationship, such as an adjacent relationship. The method of indicating the adjacent relationship is described in various methods mentioned in this application or other possible methods. Alternatively, the SSB indexes are divided into groups, and the SSB groups have an association relationship, and the SSB indexes between groups can be independent or have a specific relationship.

[0082] The SSB groups have an association relationship, specifically including: the adjacent SSB group indexes have an association relationship, such as: the SSB group index 0 and the SSB group index 1 have an association relationship, the SSB group index 1 and the SSB group index 2 have an association relationship, and so on, the SSB group index n-2 and the SSB group index n-1 have an association relationship, in addition, the SSB group index 0 and the SSB group index n-1 also have an association relationship, or they are independent.

[0083] In one embodiment, the association relationship between the synchronization signal block group indexes of the first signaling configuration is: for one SSB group index, its associated SSB group index is configured, such as: SSB group #b0{SSB group index c0, SSB index c1, SSB index c2,...}, SSB group #b1{SSB group index c3, SSB index c4, SSB index c5,...}; or, in the form of a list, for one SSB index, its corresponding SSB index is configured, SSB index #d0{SSB index d00, SSB index d01, SSB index d02,...}, SSB index #d1{SSB index d10, SSB index d11, SSB index d12,...}, SSB index #d2{SSB index d20, SSB index d21, SSB index d22,...}...; or, in the form of bitmap, each bit corresponds to an SSB index, and one SSB corresponding SSB index is configured.

[0084] In one embodiment, the association relationship between the synchronization signal group indexes of the set interval is: the association relationship is determined according to the pre-defined or signaling configured interval, such as: assuming that the interval is q, SSB group #0 and SSB group #q have an association relationship, SSB group #1 and SSB group #q+1 have an association relationship, SSB group #x and SSB group #x+q have an association relationship, etc.

[0085] In one example, the association relationship between the synchronization signal block indexes includes:

[0086] The synchronization signal block group index has a second association relationship between the synchronization signal block indexes in the group indicated by the synchronization signal block group index.

[0087] The second association relationship can be understood as the association relationship between the synchronization signal block indexes corresponding to the synchronization signal blocks in the synchronization signal block group.

[0088] It can be understood that the second association relationship is different from the first association relationship; or, the priority of the second association relationship is higher than that of the first association relationship, or the second association relationship and the first association relationship have a containing relationship;

[0089] For example, the second association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same second measurement set, and the first association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same first measurement set, wherein the first measurement set can be understood as a measurement association set corresponding to the synchronization signal block group index with the first association relationship, and the second measurement set can be understood as a measurement association set corresponding to the synchronization signal block index with the second association relationship; the first measurement set includes the second measurement set; or, when the terminal measures, the first measurement set is determined according to the second association relationship first, the second measurement set is determined according to the first association relationship when the condition is not met, and the third measurement set is determined when the condition is still not met, wherein the third measurement set can be understood as a measurement set corresponding to part or all of the remaining synchronization signal block indexes when the first measurement set and the second measurement set do not meet the condition;

[0090] Alternatively, the second association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same spatial association set, and the first association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same regional association set.

[0091] Alternatively, the second association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same synchronization association set (for example, having a downlink synchronization or uplink synchronization relationship), and the first association relationship indicates that the synchronization signal block indexes with the association relationship are located in the same regional association set.

[0092] In an example, the group indicated by the synchronization signal block group index is obtained in one or more of the following ways:

[0093] The synchronization signal block group is determined according to the interval of the synchronization signal block indexes in the group, the synchronization signal block group is determined according to the number of groups of the synchronization signal block indexes, the synchronization signal block group is obtained by dividing the synchronization signal blocks in sequence according to the synchronization signal block group index, and one synchronization signal block index corresponding to a synchronization signal block group index is obtained through the second signaling.

[0094] The synchronization signal block group can be understood as a set of synchronization signal blocks. The second signaling can be understood as signaling obtained through second signaling configured by the second communication node, and the signaling is used to obtain one synchronization signal block index corresponding to a synchronization signal block group index.

[0095] Specifically, the synchronization signal block group is determined according to the interval of the synchronization signal block indexes in the group in the following way: the grouping is determined according to the number N of SSB indexes and the size W of the group, for example: the interval is ceil(N / W), or floor(N / W); let the interval be T, SSB indexes 0, T, T*2,... form a group, SSB indexes 1, T+1, T*2+1,... form a group,..., and SSB indexes T-1, T+T-1, T*2+1,... form a group.

[0096] Specifically, the manner of determining the synchronization signal block group according to the number of groups of the synchronization signal block group index is as follows: let the number of groups be Y, SSB indexes 0, Y, Y*2,... form a group, SSB indexes 1, Y+1, Y*2+1,... form a group,..., SSB indexes Y-1, Y+Y-1, Y*2+1,... form a group, and the number of groups is equal to the interval; or, the signaling configures the interval, the number of groups, or the size of the group.

[0097] Specifically, the manner of dividing the synchronization signal blocks in sequence to obtain the synchronization signal block group according to the synchronization signal block group index is as follows: if a group includes J synchronization signal block indexes, SSB indexes 0, 1,..., J-1 form a group, SSB indexes J, J+1,..., J+J-1 form a group, and so on; if the remaining synchronization signal block indexes are insufficient for a group, the number of synchronization signal block indexes in the last group can be less than J; J is determined according to the number of synchronization signal block indexes N and the number of groups H, such as ceil(N / H) or floor(N / H); or, J is determined according to signaling indication.

[0098] Specifically, the manner of obtaining the synchronization signal block index corresponding to a synchronization signal block group index through the second signaling is as follows: a list is used to configure the synchronization signal block indexes corresponding to each SSB group, SSB group #a0{SSB index a00, SSB index a01, SSB index a02,...}, group #a1{SSB index a10, SSB index a11, SSB index a12,...}, SSB group #a2{SSB index a20, SSB index a21, SSB index a22,...},..., or a bitmap is used, each bit corresponds to a synchronization signal block index, and the synchronization signal block indexes corresponding to each SSB group are configured, or the start synchronization signal block index and the number of consecutive synchronization signal block indexes are used to indicate.

[0099] The signaling mentioned in the above manner can be transmitted on a physical broadcast channel (Physical Hybrid Automatic Repeat Request Indicator Channel, PBCH), and / or carried by a demodulation reference signal (Demodulation Reference Signal, DMRS) of the PBCH, and / or transmitted by an information block (System Information Bblock, SIB), and / or transmitted by a physical layer downlink control channel (Downlink Control Information, DCI), and / or transmitted by a MAC control element (MAC Control Element, MAC CE), and / or transmitted by radio resource control (Radio Resource Control, RRC) signaling.

[0100] Whether the association relationship exists or not can be indicated by signaling, such as 1-bit indicating whether the association relationship exists or not, or whether the association relationship exists or not is determined by whether the signaling in the above manner exists, such as: if there is association relationship configuration signaling, there is association relationship, and if there is no association relationship configuration signaling, it can be considered that each SSB index is independent.

[0101] The specific manner of the adjacent relationship can also be indicated by signaling, as described in the above examples.

[0102] The synchronization signal block group mentioned above can be independently turned on or off; the signaling carried by the PBCH, the DMRS of the PBCH, the DCI, and the SIB can indicate the corresponding SSB group to be deactivated (silenced / off) or activated (turned on).

[0103] S120, detecting the synchronization signal block based on the association relationship, obtaining a synchronization signal block index that meets the condition.

[0104] The condition can be determined based on the scene, and the conditions corresponding to different scenes are different. For example, in a measurement scene, the condition can be a measurement-related condition, which is not limited here.

[0105] In one embodiment, based on the association relationship, a set of synchronization signal blocks associated with the current synchronization signal block is determined, each synchronization signal block in the associated set of synchronization signal blocks is detected, and it is determined whether there is a synchronization signal block that meets the condition in the set of synchronization signal blocks. If there is, the index corresponding to the synchronization signal block that meets the condition is the synchronization signal block index that meets the condition, and if there is not, other sets of synchronization signal blocks are selected for detection.

[0106] The current synchronization signal block can be considered as the currently detected synchronization signal block.

[0107] The information transmission method provided in the application is applied to the first communication node side, and in the first communication node, an association relationship between synchronization signal block indexes is acquired, the association relationship indicating synchronization signal block indexes having an association relationship in a cell; and based on the association relationship, detection of the synchronization signal block is performed to obtain synchronization signal block indexes meeting a condition. The detection based on the association relationship between the synchronization signal block indexes solves the problem of large detection power consumption caused by the blind detection method in the process of SSB detection of the terminal at present, and the application realizes detection of the synchronization signal block through the association relationship, reduces the detection power consumption, and improves the detection efficiency.

[0108] In an embodiment, the association relationship between the synchronization signal block indexes is acquired, including:

[0109] a1, acquiring second signaling.

[0110] b1, determining the association relationship between the synchronization signal block indexes according to the second signaling.

[0111] In the embodiment, the second signaling sent by the second communication node is acquired, and the second signaling indicates synchronization signal block indexes having an association relationship in a cell. Based on the synchronization signal block indexes having an association relationship in the cell indicated by the second signaling, the association relationship between the synchronization signal block indexes is determined.

[0112] In an embodiment, the association relationship between the synchronization signal block indexes is acquired, including:

[0113] a2, acquiring an association relationship between transmission node indexes associated with the synchronization signal block indexes.

[0114] In SSB transmission, a transmission node (Teleport, TP) and a transmission node index (TP index) are introduced, each TP has an associated group of SSB indexes, and the SSB of each TP is transmitted according to a predefined position in a time window, and the SSB in the time window is periodically transmitted; the time window can be 5ms or 10ms, and different time window sizes are defined for different frequency points or frequency bands (such as FR1, FR2, FR3, etc.), such as 5ms for FR1, 2ms for FR2, and 1ms for FR3, or 5ms for FR1 and FR2, and 1ms or 2ms for FR3, etc.; the period can be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, 320ms, etc.; for example, the SSB indexes are numbered from 0, and the total number of SSB indexes is m, then the SSB indexes are numbered as 0, 1, 2,..., n-1; it can be understood that the SSB indexes included in one TP can be independent or have an association relationship;

[0115] Specifically, there can be several transmission nodes under one cell, one transmission node can correspond to several synchronization signal blocks or several synchronization signal block groups, therefore, the transmission nodes and the synchronization signal blocks have an association relationship, and correspondingly, the transmission node indexes and the synchronization signal block indexes have an association relationship. The association relationship between the transmission node indexes is obtained.

[0116] b2, determining the association relationship between the associated synchronization signal block indexes according to the association relationship between the transmission node indexes.

[0117] Specifically, the transmission node indexes have an association relationship, and the transmission nodes are associated with several synchronization signal blocks, and correspondingly, the association relationship between the synchronization signal blocks associated with each transmission node is determined according to the association relationship between the transmission node indexes, and then the association relationship between the synchronization signal block indexes is determined.

[0118] The embodiment can determine the association relationship between the transmission node indexes as the association relationship between the synchronization signal block indexes associated with the transmission nodes.

[0119] In an example, the association relationship between the transmission node indexes associated with the synchronization signal block indexes includes one or more of the following: the association relationship between adjacent transmission node indexes; the association relationship between transmission node group indexes; and the association relationship between the transmission node indexes within the group indicated by the transmission node group index.

[0120] The transmission nodes TP can be independent or have an association relationship, the adjacent two transmission nodes have an association relationship, and correspondingly, the adjacent two transmission node indexes also have an association relationship; each transmission node in the cell is divided into a transmission node group, and there can be multiple transmission node groups in one cell, and the transmission node groups can have an association relationship, and correspondingly, the transmission node group indexes corresponding to the transmission node groups also have an association relationship; the transmission nodes in the transmission node group have an association relationship, and correspondingly, the transmission node indexes corresponding to the transmission nodes also have an association relationship. The adjacent transmission node indexes can be obtained through signaling configuration.

[0121] It can be understood that the adjacent relationship of the transmission node indexes, the grouping of the transmission nodes, the grouping of the transmission node indexes, and the way of signaling configuring the adjacent transmission node indexes of the transmission nodes are consistent with the configuration method of the synchronization signal block indexes in the above embodiments, and the synchronization signal block SSB index is replaced by the transmission node TP index. This embodiment will not be repeated here.

[0122] For example, a list is used to configure the corresponding TP index for a TP index, TP index #d0 {TP index d00, TP index d01, TP index d02,...}, TP index #d1 {TP index d10, TP index d11, TP index d12,...}, TP index #d2 {TP index d20, TP index d21, TP index d22,...}, or a bitmap is used, each bit corresponds to a TP index, and a TP corresponding TP index is configured; A SSB index and or period corresponding to a TP can be independently configured; A SSB of a TP can be independently activated or deactivated; The signaling carried by PBCH, DMRS of PBCH, DCI and SIB can be used to indicate the deactivation (silence / closure) or activation (opening) of the SSB corresponding to the TP; The information content carried by the PBCH corresponding to a TP can be the same or independently configured. The TP index can be indicated by at least one of the secondary synchronization signal sequence, the signaling carried by PBCH, and the DMRS sequence of PBCH.

[0123] In one embodiment, the transmission node index and the cell identity are carried in one sequence; or the transmission node index is carried in a separate sequence; or the transmission node index is transmitted through the transmission node signal.

[0124] Wherein, the cell identity can be understood as the identity of the cell where the transmission node is located, expressed in the form of N ID The transmission node signal can be understood as the information transmission signal specific to the transmission node. When the secondary synchronization signal sequence d SSS (n) carries TP index information, let the TP index be F, the value of which is 0 to Z-1, and the number of TP indexes be Z.

[0125] Specifically, when the transmission node index and the cell identity are carried in one sequence, if the transmission node TP index and the cell identity and are carried in one sequence, they are expressed by the following formula:

[0126] d SSS (n) = [1-2x0((n+m0)mod127)][1-2x1((n+m1)mod127)]

[0127]

[0128] 0≤n<127

[0129] Wherein, x0 and x1 both represent a subsequence of d SSS (n) sequence.

[0130] If the transmission node TP index information and the cell identity The transmission point index is carried in one sequence, expressed by the following formula:

[0131] d SSS (n) = [1 - 2x0((n + m0) mod 127)] [1 - 2x1((n + m1) mod 127)]

[0132]

[0133] 0≤n<127

[0134] In particular, the transmission point index is carried in a separate sequence, expressed by the following formula:

[0135] d SSS (n) = [1 - 2x0((n + m0) mod 127)] [1 - 2x1((n + m1) mod 127)] [1 - 2x2((n + m2) mod 127)]

[0136]

[0137] m2=F

[0138] 0≤n<127

[0139] In the formula, x2 represents a subsequence of the d SSS (n) sequence. Wherein,

[0140]

[0141] Wherein, the transmission mode of the transmission point index by the transmission point signal is: in addition to the primary synchronization signal and the secondary synchronization signal, define the transmission point signal, transmit TP index information through the transmission point signal; the sequence corresponding to the transmission point signal can be a ZC sequence or a Gold sequence or a m sequence, and the Gold sequence r(m) is generated in the following manner: In the formula, the pseudo-random sequence c(n) is generated by the following 31-long Gold sequence, and the output sequence length is MP N .

[0142] Wherein, n = 0, 1,..., M PN -1,N C = 1600,

[0143] Wherein, the initial value of x1(n) is x1(0) = 1, x1(n) = 0, n = 1, 2,..., 30, and x2(n) is defined by to define the initial value,

[0144] It can be understood that the period of the transmission node signal can be independently configured, or the transmission node signal and the SSB can be jointly transmitted, such as being located before the SSB or being located after the SSB, or the transmission node signal and the primary / secondary synchronization signal can be jointly transmitted.

[0145] In an example, the information transmission method further includes:

[0146] Obtaining first access resource configuration information corresponding to the synchronization signal block group index.

[0147] The first access resource configuration information can be understood as configuration information related to the resource corresponding to the synchronization signal block group index configured by the second communication node. The first access resource can be, for example, a PRACH resource.

[0148] Specifically, when the synchronization signal block indexes between the synchronization signal block groups have an adjacent relationship, the second communication node configures the PRACH resource corresponding to the synchronization signal block group index as the first access resource configuration information. The first communication node receives the second communication node configuration information, and establishes the association between the SSB and the first access resource configured by the first access resource configuration information.

[0149] In an example, the first access resource has a mapping relationship with the synchronization signal block index within the group indicated by the synchronization signal block group index according to a first set order.

[0150] The first set order can be understood as a pre-set index mapping order associated with the synchronization signal block corresponding to the synchronization signal block group. For example, it can be the order of time domain first, frequency domain second, and code domain last, or the order of frequency domain first, code domain second, and time domain last.

[0151] Specifically, the mapping relationship between the synchronization signal block index and the corresponding configured first access resource index is mapped according to the synchronization signal block index within the synchronization signal block group and the configured PRACH resource order. The synchronization signal block index within the synchronization signal block group and the configured first access resource can be mapped according to the order of PRACH resource time domain index first, PRACH frequency domain resource index second, and PRACH code domain resource index last. The mapping relationship can also be that the synchronization signal block index within the synchronization signal block group and the configured first access resource are mapped according to the order of PRACH frequency domain resource index first, PRACH code domain resource index second, and PRACH resource time domain index last. The synchronization signal block index within the synchronization signal block group and the configured first access resource can also be mapped in the mapping manner of 5G NR.

[0152] The mapping relationship between the first access resource and the synchronization signal block index can enable the second communication node to determine the SSB index associated with the first communication node based on the first access resource in the process of communication between the first communication node and the second communication node.

[0153] In an example, the information transmission method further includes:

[0154] Obtaining second access resource configuration information corresponding to the transmission node index.

[0155] The second access resource configuration information can be understood as configuration information associated with resources corresponding to the transmission node index configured by the second communication node. The second access resource can be, for example, a PRACH resource.

[0156] When the transmission node index has an adjacent relationship, the second communication node configures the PRACH resource corresponding to the transmission node index, i.e., the second access resource configuration information. The first communication node receives the second communication node configuration information and establishes the association between the SSB and the first access resource configured by the second access resource configuration information.

[0157] In an example, the second access resource has a mapping relationship with the synchronization signal block index corresponding to the transmission node index according to a second set order.

[0158] The second set order can be understood as a pre-set index mapping order associated with the synchronization signal block corresponding to the transmission node, for example, an order of first time domain, then frequency domain, and finally code domain, or an order of first frequency domain, then code domain, and finally time domain.

[0159] Specifically, the mapping relationship between the synchronization signal block index corresponding to the transmission node and the PRACH resource index corresponding to the transmission node is mapped according to the order of the synchronization signal block index corresponding to the transmission node and the configured PRACH resource. The synchronization signal block index corresponding to the transmission node and the configured second access resource can be mapped according to the order of first PRACH resource time domain index, then PRACH frequency domain resource index, and finally PRACH code domain resource index. The mapping relationship can also be that the synchronization signal block index corresponding to the transmission node and the configured second access resource are mapped according to the order of first PRACH frequency domain resource index, then PRACH code domain resource index, and finally PRACH resource time domain index. The synchronization signal block index corresponding to the transmission node and the configured PRACH resource can also be mapped in the mapping manner of 5GNR.

[0160] In an example, the detection of the synchronization signal block based on the association relationship obtains a synchronization signal block index that meets a condition, including:

[0161] a3, determine a synchronization signal block set associated with the current synchronization signal block based on the association relationship.

[0162] The current synchronization signal block can be understood as a currently detected synchronization signal block. The synchronization signal block set can be understood as a set of synchronization signal blocks, and there are a plurality of synchronization signal block sets in a cell. The synchronization signal blocks in the synchronization signal block set are to be detected.

[0163] Specifically, the first communication node determines the synchronization signal block set based on the definition of the association relationship between the synchronization signal block indexes or based on the association relationship between the synchronization signal block indexes configured by the signaling. For example, the first communication node measures all synchronization signal block indexes, finds one or more best synchronization signal block indexes, and performs measurement. The first access resource corresponding to the synchronization signal block index can be determined according to the synchronization signal block index. When the measurement determination condition is not met, the synchronization signal block set can be determined based on the association relationship, so as to detect the synchronization signal blocks in the synchronization signal block set.

[0164] In the process of determining the synchronization signal block set, the synchronization signal block set can be formed from the synchronization signal blocks with the second association relationship first, and then the synchronization signal block set can be formed from the synchronization signal blocks with the first association relationship (i.e., the intra-group detection is performed first, and then the inter-group detection is performed, and the association relationship exists in both the intra-group and the inter-group); when only the first association relationship exists between the synchronization signal blocks, the synchronization signal block set can be formed from the synchronization signal blocks with the first association relationship; when only the second association relationship exists between the synchronization signal blocks, the synchronization signal block set can be formed from the synchronization signal blocks with the second association relationship.

[0165] In the process of determining the synchronization signal block set, the operation can determine a set formed by the current synchronization signal block associated or adjacent synchronization signal block indexes, and determine the set as the synchronization signal block set for detection.

[0166] b3, detecting the synchronization signal blocks in the synchronization signal block set to obtain the synchronization signal block indexes in the synchronization signal block set that meet the condition.

[0167] According to the current synchronization signal block, the synchronization signal blocks in the synchronization signal block set are detected to determine the synchronization signal block indexes in the synchronization signal block set that meet the condition.

[0168] In an example, the method further includes:

[0169] When there is no synchronization signal block in the synchronization signal block set that meets the condition, other synchronization signal block sets are selected for detection.

[0170] When there is no synchronization signal block satisfying the condition in the synchronization signal block set associated with the current synchronization signal block, the first communication node determines other synchronization signal block sets associated with the synchronization signal block set and detects synchronization signal blocks in the other synchronization signal block sets to determine a synchronization signal block index satisfying the condition. If there is still no synchronization signal block index satisfying the condition in the other synchronization signal block sets, the first communication node can detect other synchronization signal block sets that are not associated or not adjacent, and determine whether there is a synchronization signal block index satisfying the condition; if no synchronization signal block index satisfying the condition is found in all synchronization signal block sets corresponding to the entire cell, the first communication node detects synchronization signal block indexes of the same frequency or adjacent frequency cells, finds a synchronization signal block index satisfying the condition, and performs measurement or synchronization or camping or access, etc.

[0171] In an example, in the connected state, the association relationship between the synchronization signal block indexes is in one or more of the following relationships:

[0172] Channel state information;

[0173] Phase tracking reference signal;

[0174] Physical downlink control channel.

[0175] In the connected state, the second communication node can configure the association relationship between the synchronization signal block indexes to be in any one or more of the channel state information, the phase tracking reference signal, and the physical downlink control channel.

[0176] Specifically, the base station can configure the QCL relationship between the synchronization signal block group or the transmission node and the connected terminal measurement channel state information (Channel State Information, CSI) set through RRC signaling or DCI;

[0177] The base station can configure the QCL relationship between the synchronization signal block group or the transmission node and the connected terminal measurement phase tracking reference signal (Phase-tracking reference signals, PTRS) through RRC signaling or DCI;

[0178] The base station can configure the QCL relationship between the synchronization signal block group or the transmission node and the connected terminal detected physical downlink control channel (Physical Downlink Control Channel, PDCCH) search space through RRC signaling or DCI.

[0179] In an example, the transmission power of the synchronization signal block indexes corresponding to the synchronization signal block indexes in the group indicated by the synchronization signal block group index is the same.

[0180] Specifically, the transmission power of each synchronization signal block corresponding to the synchronization signal block index in the synchronization signal block group indicated by the synchronization signal block group index is the same.

[0181] The information transmission method further includes:

[0182] Obtaining the transmission power configuration information corresponding to the synchronization signal block group index.

[0183] The transmission power configuration information can be understood as the configuration information of the transmission power corresponding to the synchronization signal block group index.

[0184] Specifically, the transmission power configuration information corresponding to the synchronization signal block group index transmitted by the second communication node is obtained, so as to perform synchronization signal block detection based on the transmission power.

[0185] On the basis of the above-mentioned embodiments, variant embodiments of the above-mentioned embodiments are proposed, and it should be noted that, in order to make the description brief, only the differences from the above-mentioned embodiments are described in the variant embodiments.

[0186] In one exemplary embodiment, the present application also provides an information transmission method, Figure 3 Another configuration method provided by the embodiments of the present application is shown in the flowchart. The method can be applied to the case of information transmission of the association relationship between synchronization signal block indexes.

[0188] S210, determining the association relationship between synchronization signal block indexes, the association relationship indicating the synchronization signal block indexes having the association relationship in the cell.

[0189] Specifically, there are a plurality of transmission nodes in the cell under the jurisdiction of the base station, and the transmission nodes can have an association relationship. Each transmission node includes a plurality of synchronization signal blocks, and the synchronization signal blocks can also have an association relationship. Therefore, the association relationship between the transmission nodes corresponding to the cell is first determined, and then the association relationship between the transmission node indexes is determined; according to the association relationship between the transmission node indexes, the association relationship between the synchronization signal block indexes associated with the transmission node indexes is determined.

[0190] S220, transmitting a synchronization signal block based on the association relationship between the synchronization signal block indexes.

[0191] Specifically, the terminal of the first communication node needs to perform synchronization signal block index detection based on the association relationship during movement, and therefore, at the second communication node side, synchronization signal blocks are transmitted to the first communication node based on the association relationship between synchronization signal block indexes in the same cell. In addition, for a distributed node without a terminal residing therein, the network can also not transmit synchronization signal blocks or transmit synchronization signal blocks with a large period at the distributed node.

[0192] The information transmission method provided in the present application is applied to the second communication node side, and at the second communication node, the association relationship between synchronization signal block indexes is determined, and the association relationship indicates synchronization signal block indexes in the cell that have the association relationship; and synchronization signal blocks are transmitted based on the association relationship between the synchronization signal block indexes. The transmission of the synchronization signal blocks based on the association relationship between the synchronization signal block indexes reduces the power consumption of the network in transmitting the synchronization signal blocks, and realizes network energy saving.

[0199] a5. generating first signaling indicating the synchronization signal block group indexes in the cell that have the association relationship based on the association relationship between the synchronization signal block group indexes.

[0200] Specifically, the first signaling indicating the synchronization signal block group indexes in the cell that have the association relationship is generated based on the association relationship between the synchronization signal block group indexes, and the synchronization signal block group indexes in the cell that have the association relationship are indicated through the first signaling.

[0201] b5. transmitting the first signaling.

[0202] Specifically, the first signaling is transmitted to the first communication node.

[0203] In an example, the association relationship between the synchronization signal block indexes includes:

[0207] Or,

[0208] The synchronization signal block indexes in the synchronization signal block group index have a second association relationship.

[0209] Specifically, a region can include a plurality of synchronization signal block groups, and the synchronization signal block groups have corresponding synchronization signal block group indexes; a synchronization signal block group can include a plurality of synchronization signal blocks, and the synchronization signal blocks have corresponding synchronization signal block indexes; the synchronization signal block groups in the same region can have an association relationship, and correspondingly, the synchronization signal block group indexes have a first association relationship. The first association relationship includes an association relationship between adjacent synchronization signal block group indexes, an association relationship between the synchronization signal block group indexes configured by the first signaling, and an association relationship between the synchronization signal group indexes with a set interval; the synchronization signal blocks in the same synchronization signal block group can also have an association relationship, and correspondingly, the synchronization signal block indexes have a second association relationship.

[0210] In an example, the synchronization signal block group indexes are obtained in one or more of the following ways:

[0217] Specifically, in a cell, there are a plurality of transmission nodes, and there can be a corresponding association between the transmission nodes. Based on the transmission node index adjacency relationship, transmission node grouping, transmission node index grouping, and content of signaling configuring the adjacent transmission node indexes of the transmission node described in the above embodiments, the association between the transmission node indexes is determined.
