Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a signaling information transmission method, apparatus, network-side equipment, and terminal. Background Technology

[0002] In the New Radio Terrestrial Network (NR TN), the Synchronization Signal and Physical Broadcast Channel Block (SSB) are transmitted via beam scanning, while the Physical Downlink Shared Channel (PDSCH), which carries System Information Block (SIB) information, is transmitted via broadcast. The two are linked by signaling indication.

[0003] However, in some scenarios, there is a relatively high beam gain requirement, which further highlights the conflict between link budget and beam coverage. In order to ensure the link budget requirement, the beam coverage becomes narrower. Therefore, the number of beams required is more than in the general scenario of terrestrial network (TN), which further leads to less available time and frequency resources. At the same time, the method of using SSB scanning transmission and PDSCH channel broadcast transmission will cause an imbalance in the link budget of the two channels.

[0004] Furthermore, in these scenarios with high beam gain requirements, a larger number of beams are needed, which consumes more time and frequency resources. This means that it takes longer for the base station to complete a scanning cycle. If the terminal fails to complete the signaling interaction in time during this scanning cycle, such as initial access, it will have to wait for a long time until the next scanning cycle.

[0005] In summary, the existing technology has several drawbacks. First, the transmission methods of SSB and PDSCH are different. Second, when there is a high beam gain requirement, the available time and frequency resources become less, and the method of using SSB scanning transmission and PDSCH channel broadcast transmission will cause an imbalance in the link budget of the two channels. Third, when there is a high beam gain requirement, the number of beams is large, and the time for the base station to complete a scanning cycle becomes longer. Summary of the Invention

[0088] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0089] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0090] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0091] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0092] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0093] It should be noted that in NR, as the number of synchronization signal blocks (SSBs) increases, their resource consumption increases and the SSB scanning cycle lengthens. In order to complete fast beam scanning and timely random access, it is necessary to simplify the design of SSB, PDCCH, and SIBx information of terrestrial and non-terrestrial networks, and simplify the configuration parameters related to random access, so that the base station can complete beam scanning in a shorter time period and the terminal can complete cell selection in a shorter time period.

[0094] This invention addresses the shortcomings of existing technologies, such as the different transmission formats of SSB and PDSCH, the imbalance of the two-channel link budget when there are high beam gain requirements, and the increased time for the base station to complete a scanning cycle. It proposes a signaling information transmission method, apparatus, network-side equipment, and terminal, including necessary channels for cell search and random access in NR and TN, such as the Synchronization Signal Block (SSB), PDCCH, and the corresponding PDSCH carrying SIBx information. This resource set is transmitted under the same scanning beam. Furthermore, this invention simplifies the channel carrying information: the design of MIB information, DCI information carried by PDCCH, and SIBx information is simplified to reduce the resource consumption of initial synchronization and cell search information. Further, this invention simplifies the channel configuration indication process: the initial synchronization, cell search process, and related information are simplified to complete initial synchronization within a shorter time period and initiate uplink random access promptly.

[0095] like Figure 1 As shown, an embodiment of the present invention provides a signaling information transmission method applied to a network-side device, comprising:

[0096] Step 100: During the dwell time of one wavelength of the first beam, N first resource sets are transmitted; the dwell time of the wavelength is the time required for any wavelength in the first beam to dwell.

[0097] Wherein, N is an integer greater than or equal to 0; the first resource set includes: the minimum combination of channels and signals required for any terminal to complete cell search.

[0098] It should be noted that, normally, N equals 1, but can also be greater than 1; in special cases, N can equal 0. Because the content carried by the first beam is not limited to the first resource set, when the first beam is used for other purposes, except for initial access, the content carried by the first beam does not include the first resource set, in which case N = 0.

[0099] It should also be noted that the scanning characteristics of the first beam include: during beam scanning, the network-side equipment (base station) periodically scans all positions within the coverage area of ​​the first beam in a certain order; the beam used is called the first beam; wherein, the number of positions is M. The time difference between the start of one round of scanning and the start of the next round of scanning is called the scanning period T of the first beam. s Wherein, the wave position residence time T b The time required for any position in the first beam to remain; the T b For an integer number of time slots, i.e. (T) b *2 μ slots (time slots) or (T) b *2 μ*X)symbols, where X is the number of symbols in each slot, typically 12 or 14, depending on actual needs; μ∈{0,1,2,3,4,5} is the configuration parameter for the subcarrier spacing. Additionally, T s A blank period T may exist within it. w (T w ≥0), in T w Within this network, the network-side equipment (base stations) can be flexibly configured. w T s and T b The relationship is: T s -M*T b =T w .

[0100] The technical solution of the present invention transmits the first resource set of necessary channels involved in cell search and random access under the same scanning beam, and can shorten the scanning cycle of network-side equipment in scenarios with high beam gain requirements.

[0101] Optionally, the first resource set includes:

[0102] Synchronization signal and physical broadcast channel block (SSB);

[0103] or,

[0104] SSB and Physical Downlink Shared Channel (PDSCH);

[0105] or,

[0106] SSB, PDSCH, and Physical Downlink Control Channel (PDCCH).

[0107] In this embodiment, N first resource sets are transmitted within one wavelength dwell time of the first beam. When N is greater than or equal to 1, the first resource set includes, but is not limited to, the following three forms: SSB; SSB+PDSCH; and SSB+PDCCH+PDSCH. The first resource set in this invention provides necessary information for the terminal to perform cell search and initiate random access. Transmitting the first resource set under the same scanning beam changes the different transmission forms of SSB and PDSCH in the prior art, simplifying the information interaction between the base station and the terminal.

[0108] Optionally, the SSB includes a primary synchronization signal PSS, a secondary synchronization signal SSS, a physical broadcast channel PBCH, and a demodulation reference signal DMRS;

[0109] Among them, PSS and SSS are used for downlink time-frequency synchronization and to carry cell ID information; PBCH scrambling code can carry MIB type information, and PBCH payload carries MIB information; DMRS is used to provide estimation and equalization of the PBCH channel, and to carry index information of the SSB;

[0110] Here, PSS and SSS are used together for downlink time-frequency synchronization and to carry cell ID information; PBCH mainly carries MIB information, and also contains timing-added information. PBCH scrambling code can also carry some information; there are various types of MIB, which can be indicated by PBCH scrambling code; DMRS is used to provide a reference for the terminal to perform downlink demodulation, that is, to provide the estimation and equalization of the PBCH channel, and to carry the index information of the SSB.

[0111] Optionally, the PBCH in the SSB carries key information, such as the PBCH scrambling code carrying MIB type information, and the PBCH payload carrying MIB information. This invention indicates the MIB type by using different scrambling sequences for the bits of the PBCH, for example, by employing different cyclic shifts in the scrambling sequence; of course, a fixed configuration method can also be used to select one type. For example, the 2 bits of information carried by the scrambling sequence indicate four MIB types. A MIB type indication table designed in this scheme is shown in Table 1 below:

[0112] Table 1: MIB Type Indicator Table

[0113] Bit 1 Bit 2 MIB type 0 0 1 0 1 2 1 0 3 1 1 4

[0114] Specifically, when the 2-bit information is 00, the MIB is of the fourth type; when the 2-bit information is 01, the MIB is of the first type; when the 2-bit information is 10, the MIB is of the second type; and when the 2-bit information is 11, the MIB is of the third type.

[0115] Optionally, the PDCCH carries downlink control information (DCI) indicating the channel configuration information of the PDSCH;

[0116] The PDSCH carries the System Information Block (SIBx) information, which includes the necessary information for the terminal to initiate random access.

[0117] In this embodiment, SIBx is a newly defined SIB. Of course, the content of SIBx can be the same as or similar to some of the content in SIB1 of NR. In actual needs, SIBx can be represented as SIB1, SIB2, etc., depending on the different content represented by the SIB.

[0118] It should be noted that the aforementioned SSB consists of PSS, SSS, PBCH channel, and DMRS symbols. The PBCH channel carries MIB information, which includes various field designs, and the PBCH channel itself also has various designs, differing from the existing NR standard. The PDCCH carries DCI information, which also includes various field designs, differing from the existing NR standard. The PDSCH carries SIBx information, which includes various field designs; this invention preferentially selects SIB1, defining it as a type of SIB information, also differing from the existing NR standard. This invention redefines the bearer information of the SSB, PDCCH, and PDSCH in the first resource set, simplifying the first resource set and reducing the resource consumption of initial synchronization and cell search information.

[0119] Optionally, the MIB type information is used to indicate the MIB type; when the MIB type is the first type, in the first resource set: MIB messages exist, but DCI messages and SIBx information do not exist; when the MIB type is the second type, in the first resource set, MIB messages and SIBx messages exist, but DCI messages do not exist; when the MIB type is the third type, MIB messages and SIBx messages exist, but DCI messages do not exist; when the MIB type is the fourth type, in the first resource set, MIB messages, DCI messages, and SIBx messages all exist.

[0120] Optionally, the MIB type information is used to indicate the MIB type;

[0121] When the MIB type is the first type, the corresponding MIB information includes: pre-set main field information and the first configuration parameter set of the Physical Random Access Channel (PRACH);

[0122] When the MIB type is the second type, the corresponding MIB information includes: preset main field information;

[0123] When the MIB type is the third type, the corresponding MIB information includes: pre-set main field information and PDSCH configuration parameters;

[0124] When the MIB type is the fourth type, the corresponding MIB information includes: pre-set main field information, control resource set CORESET#0 configuration, and search space corresponding information; the CORESET#0 and the search space determine the time-frequency range of the PDCCH;

[0125] The degree of simplicity of the first resource set corresponding to the four MIB types is as follows: MIB type is type 1 > MIB type is type 2 > MIB type is type 3 > MIB type is type 4.

[0126] In this embodiment, the pre-set main field information in the MIB information corresponding to the four MIB types can include: system frame number, common subcarrier spacing, SSB subcarrier offset, cell prohibition, co-frequency reselection, and DMRS configuration fields. Of course, in addition to these fields, other fields carried in the MIB information will differ depending on the MIB type. MIB information is highly versatile and can contain necessary information for the terminal to perform cell search, initiate random access, etc. The following is the design of other MIB fields changing with the MIB type:

[0127] When the MIB type is the first type, the corresponding MIB information includes: pre-set main field information and the first configuration parameter set of the Physical Random Access Channel (PRACH);

[0128] When the MIB type is the second type, the corresponding MIB information includes: preset main field information;

[0129] Here, when the MIB type is the second type, the corresponding MIB information has no other fields, indicating that the PDSCH configuration is a fixed configuration, that is, the PDSCH time and frequency position, interleaving mapping method, modulation and coding method and redundancy version number are all fixed configurations agreed upon in advance.

[0130] When the MIB type is the third type, the corresponding MIB information includes: pre-set main field information and PDSCH configuration parameters;

[0131] In this embodiment, the PDSCH configuration parameters are as follows: Frequency domain resource assignment field: This field indicates the frequency domain resources of the PDSCH, i.e., the number of consecutive RBs (resource blocks) of the PDSCH; when this field is omitted, this parameter is a pre-agreed fixed configuration; Time domain resource assignment field: This field indicates the time domain resources of the PDSCH; when this field is omitted, this parameter is a pre-agreed fixed configuration; Modulation and coding scheme field: This field indicates the modulation and coding scheme of the PDSCH; when this field is omitted, this parameter is a pre-agreed fixed configuration; VRB-to-PRB mapping field: This field indicates the interleaving mapping scheme of the PDSCH; when this field is omitted, this parameter is a pre-agreed fixed configuration; Redundancy version field: This field indicates the redundancy version number of the PDSCH, which is related to coding; when this field is omitted, this parameter is a pre-agreed fixed configuration.

[0132] When the MIB type is the fourth type, the corresponding MIB information includes: CORESET#0 configuration and search space information. CORESET#0 and the search space determine the time-frequency range of the PDCCH. Here, the special feature of the PDCCH is that it carries DCI information, which indicates the channel configuration carrying SIBx information. CORESET#0 determines the time-frequency resource configuration of the PDCCH (including the number of symbols in the time domain, the starting position in the frequency domain, and the length of the continuous RB in the frequency domain). The search space determines the timing (specific time domain position) when the user monitors the PDCCH. Combining CORESET#0 and the search space determines a time-frequency range in which the PDCCH is carried.

[0133] This invention defines the simplification level of the first resource set corresponding to four MIB types as follows: MIB type is the first type > MIB type is the second type > MIB type is the third type > MIB type is the fourth type. It also defines the parameter settings of MIB information corresponding to each MIB type. This invention simplifies channel bearer information, that is, it simplifies the design of MIB information and reduces the resources occupied by initial synchronization and cell search information.

[0134] Optionally, when the MIB type is the fourth type, the corresponding DCI information includes:

[0135] The fields used to indicate the frequency domain resource assignment of PDSCH, the time domain resource assignment of PDSCH, the modulation and coding scheme of PDSCH, the VRB-to-PRB mapping of PDSCH, and the Redundancy version of PDSCH are used to indicate the redundancy version number of PDSCH.

[0136] The frequency domain resource allocation field, time domain resource allocation field, modulation and coding scheme field, VRB to PRB mapping field, and redundancy version field are all preset default fields. The preset default fields include default fields and non-default fields. The preset default fields are fixed configuration fields agreed upon in advance.

[0137] In this embodiment, the PDCCH carries DCI information, indicating that the configuration information of the PDSCH channel only contains DCI information when the MIB type is the fourth type. The fields carried by the DCI information are as follows: Frequency domain resource assignment field: This field is used to indicate the frequency domain resources of the PDSCH, that is, the number of consecutive resource blocks (RBs) of the PDSCH; Time domain resource assignment field: This field is used to indicate the time domain resources of the PDSCH; Modulation and coding scheme field: This field is used to indicate the modulation and coding scheme of the PDSCH; VRB-to-PRB mapping field: This field is used to indicate the interleaving mapping scheme of the PDSCH; Redundancy version field: This field is used to indicate the redundancy version number of the PDSCH, which is related to the coding.

[0138] It should be noted that these fields differ from existing technologies in the following ways: 1. Field length is different. The field length is a preset default field, that is, a fixed configuration field agreed upon in advance. The preset default field includes a default field and a non-default field, while the fields indicated by DCI information in existing technologies do not have a default field; 2. Field indication configuration is different. For example, in existing technologies, there is a 1-bit long field. When the value is 0, it indicates that the PDSCH length is 1. In this invention, a similar field, when the value is 0, can indicate that the PDSCH length is 2 (or other numbers, which can be changed according to requirements).

[0139] Optionally, when the MIB type is the second, third, or fourth type, the corresponding SIBx information includes: the second configuration parameter set of PRACH; both the first configuration parameter set of PRACH and the second configuration parameter set of PRACH include:

[0140] Generate the parameter root sequence index of the PRACH preamble, wherein the parameter root sequence index is indicated according to a first subset within a first preset range;

[0141] In this embodiment, for the parameter root sequence index prach-RootSequenceIndex that generates the PRACH preamble, in order to simplify signaling, a subset is selected from the first subset within the first preset range, i.e., from the configurable range, and indicated by a field; when the field is defaulted, the parameter is a pre-agreed fixed configuration.

[0142] In particular, in a satellite network scenario, one fixed configuration of the present invention is as follows: the terminal can obtain the satellite network topology based on ephemeris information and Global Navigation Satellite System (GNSS) positioning, and combined with the current time and space information, determine the root sequence index that should be used at the moment.

[0143] The parameter constraint set and zero correlation field index of the preamble of PRACH are generated, and the parameter root sequence index is indicated according to a second subset within a second preset range;

[0144] Here, for the parameter constraint set and zero-related field index for generating the PRACH preamble, a subset is selected from the configurable range according to the second subset indication within the second preset range, indicated by the field; when the field is defaulted, the parameter is a pre-agreed fixed configuration.

[0145] The network-side device receives the time-domain configuration parameters of the uplink random access occasion (PRACH occasion), and the time-domain configuration parameters of the PRACH occasion are indicated according to a third subset within a third preset range.

[0146] It should be noted that for the time-domain configuration of PRACH occasions, a subset is selected from the configurable range according to the third preset range, indicated by a field. When this field is omitted, the parameter is a pre-defined fixed configuration. Different configuration methods exist depending on the use case. For example, when using uplink beam scanning, the configuration period for PRACH occasions is equal to the uplink beam scanning period.

[0147] The associated configuration parameters for SSB and PRACH occasions, wherein the associated configuration parameters are indicated according to a fourth subset within a fourth preset range;

[0148] In this embodiment, for the association configuration of SSB and PRACH occasion, the association configuration parameter is indicated by the fourth subset within the fourth preset range, that is, a subset is selected from the configurable range and indicated by a field; when the field is defaulted, the parameter is a pre-agreed fixed configuration.

[0149] Specifically, in the case of using uplink beam scanning, a fixed configuration of the present invention is as follows: the configuration period of PRACH Hoccasion is equal to the uplink beam scanning period, and also equal to the association period of SSB and PRACH occasion, as well as the association mode period. In the beam scanning scenario, the satellite coverage area is divided into several positions, and the satellite scans each position in a certain order using a scanning beam, with uplink and downlink signals transmitted within the beam. For example, in the case of using uplink beam scanning, there is an SSB for each downlink position dwell time, and there is a PRACH Hoccasion for each uplink position dwell time. At this time, each SSB corresponds to a PRACH occasion.

[0150] The resource frequency division multiplexing indication and frequency domain start indication parameters for the PRACH occasion are indicated according to the fifth subset within the fifth preset range.

[0151] It should be noted that for the PRACH occasion resource frequency division multiplexing indication and frequency domain start indication, a subset is selected from the configurable range according to the fifth subset indication within the fifth preset range, and indicated by the field; when the field is defaulted, the parameter is a pre-agreed fixed configuration. For example, when the parameter indication field is defaulted, the parameter can be fixedly configured as msg1-FDM=1 or msg1-FDM=4; here, msg1 is the process of transmitting the preamble in the PRACH channel.

[0152] The configuration parameters of PRACH mentioned above are constituted by the first subset, the second subset, the third subset, the fourth subset and the fifth subset. The first subset, the second subset, the third subset, the fourth subset and the fifth subset are all represented according to the corresponding preset fields. When any preset field is missing, the subset corresponding to the missing field is represented by the corresponding preset fixed parameter value.

[0153] In this embodiment, the first configuration parameter set of PRACH or the second configuration parameter set of PRACH are both configuration parameters that indicate PRACH, and their functions are the same. It should be noted that, however, there may be different designs depending on the different bearer message bodies, such as the selection of subsets.

[0154] The configuration parameters of PRACH mentioned above are constituted by the first subset, the second subset, the third subset, the fourth subset and the fifth subset. The first subset, the second subset, the third subset, the fourth subset and the fifth subset correspond to five fields. Each field corresponds to a part of the PRACH configuration. The configuration of PRACH needs to be determined by the five parts together.

[0155] The phrase "selecting a subset from the configurable range and indicating it via a field" for each subset mentioned above refers to the configuration range indicated by each field, which is a subset of the five configuration parts. For example, PRACH has five configuration parts, referred to as a, b, c, d, and e. The configurable range of part a is {0, 1, 2, 3}. This invention pre-defines a field indicating a subset of part a, {1, 3}, which can be set to 1 bit to indicate a number within this subset {1, 3}. When the pre-definement configuration subset is {1}, this field indication is not needed because the default value is 1.

[0156] In summary, the first resource set proposed in this invention includes the necessary channels involved in cell search and random access in NR and TN, such as the Synchronization Signal Block (SSB), PDCCH, and the corresponding PDSCH carrying SIBx information. This resource set is transmitted under the same scanning beam. In addition, this invention simplifies the channel carrying information by simplifying the design of MIB information, DCI information carried by PDCCH, and SIBx information, thereby reducing the resources occupied by initial synchronization and cell search information.

[0157] like Figure 2 As shown, an embodiment of the present invention provides a signaling information transmission method applied to a terminal, comprising:

[0158] Step 200: Receive N first resource sets transmitted by the network-side device within one wavelength dwell time of the first beam; where N is an integer greater than or equal to 0; the first resource set includes: the minimum channel and signal combination required for any terminal to complete cell search; the wavelength dwell time is the time required for any wavelength in the first beam to dwell;

[0159] Step 300: Based on the N first resource sets, perform cell search and initiate uplink random access.

[0160] This invention proposes a first resource set, which includes necessary channels for cell search and random access in NR and TN, such as the Synchronization Signal Block (SSB), PDCCH, and the corresponding PDSCH carrying SIBx information. This first resource set is transmitted under the same scanning beam. In addition, the channel carrying information is simplified: the design of MIB information, DCI information carried by PDCCH, and SIBx information is simplified to reduce the resources occupied by initial synchronization and cell search information. On this basis, the channel configuration indication process is further simplified: the initial synchronization, cell search process, and related information are simplified in order to complete the initial synchronization in a shorter time period and initiate uplink random access in a timely manner.

[0161] Furthermore, the first resource set includes:

[0162] Synchronization signal and physical broadcast channel block (SSB);

[0163] or,

[0164] SSB and Physical Downlink Shared Channel (PDSCH);

[0165] or,

[0166] SSB, PDSCH, and Physical Downlink Control Channel (PDCCH).

[0167] Specifically, the SSB includes the primary synchronization signal PSS, the secondary synchronization signal SSS, the physical broadcast channel PBCH, and the demodulation reference signal DMRS;

[0168] Among them, PSS and SSS are used for downlink time-frequency synchronization and to carry cell ID information; PBCH scrambling code can carry MIB type information, and PBCH payload carries MIB information; DMRS is used to provide estimation and equalization of the PBCH channel, and to carry index information of the SSB;

[0169] The PDCCH carries downlink control information (DCI) and indicates the channel configuration information of the PDSCH.

[0170] The PDSCH carries the System Information Block (SIBx) information, which includes the necessary information for the terminal to initiate random access.

[0171] In this embodiment of the invention, the MIB type information can be used to indicate the MIB type. When the MIB type is the first type, it indicates that the Physical Random Access Channel (PRACH) configuration parameters are carried in the MIB information. In this case, the MIB message exists, but the DCI message and SIBx information do not exist. When the MIB type is the second type, it indicates that the PDSCH configuration is fixed, and simultaneously indicates that the PRACH configuration parameters are carried in the SIBx information. In this case, the MIB message and SIBx message exist, but the DCI message does not exist. When the MIB type is the third type, it indicates that the PDSCH configuration parameters are carried in the MIB information, and simultaneously indicates that the PRACH configuration parameters are carried in the SIBx information. In this case, the MIB message and SIBx message exist, but the DCI message does not exist. When the MIB type is the fourth type, it indicates that the CORESET#0 configuration parameters and search space configuration parameters are carried in the MIB information. In this case, the MIB message, DCI message, and SIBx message all exist.

[0172] Furthermore, the MIB type information is used to indicate the MIB type;

[0173] When the MIB type is the first type, the corresponding MIB information includes: pre-set main field information and the first configuration parameter set of the Physical Random Access Channel (PRACH);

[0174] When the MIB type is the second type, the corresponding MIB information includes: preset main field information;

[0175] When the MIB type is the third type, the corresponding MIB information includes: pre-set main field information and PDSCH configuration parameters;

[0176] When the MIB type is the fourth type, the corresponding MIB information includes: pre-set main field information, control resource set CORESET#0 configuration, and search space corresponding information; the CORESET#0 and the search space determine the time-frequency range of the PDCCH;

[0177] The degree of simplicity of the first resource set corresponding to the four MIB types is as follows: MIB type is type 1 > MIB type is type 2 > MIB type is type 3 > MIB type is type 4.

[0178] Furthermore, when the MIB type is the second, third, or fourth type, the corresponding SIBx information includes: the second configuration parameter set of PRACH; both the first configuration parameter set of PRACH and the second configuration parameter set of PRACH include:

[0179] Generate the parameter root sequence index of the PRACH preamble, wherein the parameter root sequence index is indicated according to a first subset within a first preset range;

[0180] The parameter constraint set and zero correlation field index of the preamble of PRACH are generated, and the parameter root sequence index is indicated according to a second subset within a second preset range;

[0181] The network-side device receives the time-domain configuration parameters of the uplink random access occasion (PRACH occasion), and the time-domain configuration parameters of the PRACH occasion are indicated according to a third subset within a third preset range.

[0182] The associated configuration parameters for SSB and PRACH occasions, wherein the associated configuration parameters are indicated according to a fourth subset within a fourth preset range;

[0183] The resource frequency division multiplexing indication and frequency domain start indication parameters for the PRACH occasion are indicated according to the fifth subset within the fifth preset range.

[0184] The first configuration parameter set and the second configuration parameter set of PRACH are constituted by the first subset, the second subset, the third subset, the fourth subset and the fifth subset. The first subset, the second subset, the third subset, the fourth subset and the fifth subset are all represented according to the corresponding preset fields. When any preset field is missing, the subset corresponding to the missing field is represented by the corresponding preset fixed parameter value.

[0185] Furthermore, when the MIB type is the fourth type, the corresponding DCI information includes:

[0186] The PDSCH frequency domain resource allocation field is used to indicate the PDSCH frequency domain resources; the PDSCH time domain resource allocation field is used to indicate the PDSCH time domain resources; the PDSCH modulation and coding scheme field is used to indicate the PDSCH modulation and coding scheme; the PDSCH vrb to prb mapping field is used to indicate the PDSCH interleaving mapping scheme; and the PDSCH redundancy version field is used to indicate the PDSCH redundancy version number.

[0187] The frequency domain resource allocation field, time domain resource allocation field, modulation and coding scheme field, VRB to PRB mapping field, and redundancy version field are all preset default fields. The preset default fields include default fields and non-default fields. The preset default fields are fixed configuration fields agreed upon in advance.

[0188] It should be noted that the limitations regarding the MIB type information and the corresponding MIB information, the corresponding DCI information when the MIB type is the fourth type, and the corresponding SIBx information when the MIB type is the second, third, and fourth types are the same as the limitations of the network-side device. Therefore, they will not be explained here in the method section of the final version of the corresponding network-side device.

[0189] In summary, the first resource set proposed in this invention includes the necessary channels involved in cell search and random access in NR and TN, such as the Synchronization Signal Block (SSB), PDCCH, and the corresponding PDSCH carrying SIBx information. This resource set is transmitted under the same scanning beam. In addition, this invention simplifies the channel carrying information by simplifying the design of MIB information, DCI information carried by PDCCH, and SIBx information, thereby reducing the resources occupied by initial synchronization and cell search information.

[0190] Optionally, step 300 includes:

[0191] Step 310: Based on the N first resource sets, determine the first SSB of the first resource set; the first SSB is the first SSB detected by the terminal or the SSB with the highest signal-to-noise ratio;

[0192] In this embodiment, during cell search, the terminal retrieves the first SSB block detected within the current dwell time of the current wave position, or the one with the highest signal-to-noise ratio, and completes downlink time-frequency synchronization through the synchronization signals PSS and SSS within the SSB block to obtain the cell ID.

[0193] Step 320: Determine the MIB type information transmitted by the PBCH corresponding to the first SSB and the configuration information of the first resource set based on the PBCH corresponding to the first SSB.

[0194] In this embodiment, the terminal demodulates the PBCH payload and selects the scrambling sequence of the descrambled PBCH payload through blind detection to obtain the 2-bit information carried by the scrambling sequence, thereby determining the MIB type. The classification of the MIB types can be referred to Table 1 above.

[0195] Wherein, the MIB type information is used to indicate the MIB type; when the MIB type is type 1, the terminal determines that the MIB message exists, but the DCI message and SIBx information do not exist; the MIB information carries PRACH channel configuration parameters. When the MIB type is type 2, the terminal determines that the MIB message and SIBx message exist, but the DCI message does not exist; the MIB information does not carry PDSCH channel configuration parameters, and the PDSCH channel configuration parameters use a fixed configuration; the SIBx carries PRACH channel configuration parameters. When the MIB type is type 3, the terminal determines that the MIB message and SIBx message exist, but the DCI message does not exist; the MIB information carries PDSCH channel configuration parameters; the SIBx carries PRACH channel configuration parameters. When the MIB type is type 4, the terminal determines that the MIB message, DCI message, and SIBx message all exist; the MIB information carries CORESET#0 configuration parameters and search space#0 configuration parameters; the DCI information carries PDSCH configuration parameters; the SIBx carries PRACH channel configuration parameters. Specifically, after descrambling the PBCH payload, and given the known MIB type, the MIB is decoded according to the pre-agreed MIB information bit size to obtain the MIB information.

[0196] Step 330: Based on the MIB type information and the configuration information of the first resource set, determine the random access timing of the terminal corresponding to the network-side device, perform cell search, and initiate uplink random access.

[0197] In this embodiment, based on the MIB type information and the configuration information of the first resource set, the MIB information, PDCCH configuration parameters, DCI information, PDSCH configuration parameters, and SIBx information corresponding to each MIB type are determined.

[0198] Specifically, when the MIB type is the fourth type, the terminal obtains the CORESET#0 configuration parameter and the search space#0 configuration parameter from the MIB information, and uses the two to determine the time and frequency resources where the PDCCH is located.

[0199] When the MIB type is the second type, the PDSCH configuration parameters are fixed configurations agreed upon in advance.

[0200] When the MIB type is the third type, the terminal obtains the PDSCH configuration parameters from the MIB.

[0201] When the MIB type is the fourth type, the terminal determines the time-frequency resource where the PDCCH is located. The time-frequency resource where the PDCCH is located is blindly detected using different CCE aggregation degrees to obtain DCI information, and the PDSCH configuration parameters are obtained from the DCI information.

[0202] When the MIB type is Type 1, the terminal explicitly or implicitly obtains the configuration parameters of the PRACH channel based on the MIB information. If PRACH configuration parameters exist in the MIB, the terminal will know the explicitly or implicitly indicated PRACH configuration parameter fields according to the pre-agreed MIB field format. For example, if prach-RootSequenceIndex exists in the MIB, the root sequence index of the parameters for generating the PRACH preamble is explicitly indicated; if PRACH occasion resource frequency division multiplexing parameters do not exist in the MIB, the terminal uses pre-agreed fixed PRACH occasion resource frequency division multiplexing parameters for uplink random access; if no PRACH configuration parameters exist in the MIB, all PRACH configuration parameters use pre-agreed fixed values.

[0203] When the MIB type is the second type, the terminal uses default parameters (time-frequency position, modulation coding method) to obtain the time-frequency position, modulation order, and code rate of the PDSCH, decodes the SIBx information, and obtains the configuration parameters of the PRACH channel from the SIBx.

[0204] When the MIB type is the third type, the terminal obtains the time-frequency position, modulation order, and code rate of the PDSCH according to the relevant parameters (time-frequency position, modulation coding method) indicated by the fields in the MIB, decodes the SIBx information, and obtains the configuration parameters of the PRACH channel from the SIBx.

[0205] When the MIB type is the fourth type, the terminal knows the time and frequency position of the SIBx information according to the PDSCH configuration parameters in the DCI information, decodes the SIBx codeword according to the interleaving mapping method and modulation coding method indicated by the DCI, and learns the PRACH configuration parameters from the SIBx information.

[0206] Furthermore, the terminal determines the time-frequency position of all PRACH occasions based on the time-domain configuration of the PRACH occasion, the PRACH occasion resource frequency division multiplexing indication, and the frequency domain start indication; then, it determines the corresponding PRACH occasion based on the association configuration of SSB and PRACH Hoccasion and the SSB index obtained by descrambling PBCH; the terminal sends the uplink random access channel PRACH to the corresponding PRACH occasion.

[0207] Based on the MIB type information and the configuration information of the first resource set, the present invention further simplifies the channel configuration indication process, namely, simplifies the initial synchronization, cell search process and related information, so as to complete the initial synchronization in a shorter time period and initiate uplink random access in a timely manner.

[0208] Scenario 1, a method for sending signaling information applied to a terminal, including:

[0209] When the MIB type is type 2:

[0210] (1) Downlink synchronization: The terminal retrieves the first or highest signal-to-noise ratio SSB block detected during the current waveform dwell time, and completes downlink time-frequency synchronization through the synchronization signals PSS and SSS in the SSB block to obtain the cell ID.

[0211] (2) Obtain information about the MIB type:

[0212] When the terminal descrambles the PBCH and learns that the MIB type is Type II, it indicates that the PDSCH is a fixed configuration. The corresponding MIB information includes: pre-set main field information, which may include: system frame number, common subcarrier spacing, SSB subcarrier offset, cell prohibition, and co-frequency reselection, etc. Table 2 shows the corresponding MIB information when the MIB type is Type II, as designed in this invention.

[0213] Table 2: MIB information corresponding to the second type:

[0214] name Number of bits system frame number 6 Common subcarrier spacing (subCarrierSpacingCommon) 1 SSB Subcarrier Offset 4 CellBarred is prohibited in the community 1 intraFreqReselection 1

[0215] As shown in the table above, the MIB information does not contain any fields for SIBx time-frequency resources or configuration indications. In this case, the time-frequency resource-related configurations for SIBx use pre-agreed fixed values.

[0216] like Figure 3 As shown, if N SSBs are supported during the current position dwell time, and the fixed time difference between the SSB and PDSCH is T1, and the duration of the PDSCH is T... PDSCH The fixed frequency domain difference between SSB and PDSCH is N. RB_offset The length of the PDSCH persistent resource block RB is L. RB The terminal determines the PDSCH time-frequency domain resources based on the time-frequency offset from the SSB.

[0217] (3) Obtain PRACH configuration information: After that, the terminal uses the default interleaving mapping method and modulation coding method to decode SIBx and obtain the configuration parameters of the PRACH channel.

[0218] (4) Initiating uplink random access: Finally, the terminal sends a PRACH channel on the corresponding random access occasion to perform cell search and initiate uplink random access.

[0219] Scenario 2, signaling information transmission methods applied to terminals, including:

[0220] When the MIB type is type 3:

[0221] (1) Downlink synchronization: The terminal retrieves the first or highest signal-to-noise ratio SSB block detected during the current waveform dwell time, and completes downlink time-frequency synchronization through the synchronization signals PSS and SSS in the SSB block to obtain the cell ID.

[0222] (2) Obtain information about the MIB type:

[0223] When the terminal descrambles the PBCH and learns that the MIB type is type three, the corresponding MIB information includes: pre-set main field information and PDSCH configuration parameters. The pre-set main field information can include: system frame number, common subcarrier spacing, SSB subcarrier offset, cell prohibition, and co-frequency reselection, etc. Table 3 shows the corresponding MIB information for type three designed in this invention:

[0224] Table 3: MIB information corresponding to the third type:

[0225] name Number of bits system frame number 6 Common subcarrier spacing (subCarrierSpacingCommon) 1 SSB Subcarrier Offset 4 CellBarred is prohibited in the community 1 intraFreqReselection 1 Frequency domain resource assignment 8 Time domain resource assignment 2 Modulation and coding scheme 2 total 26

[0226] As shown in Table 3, the MIB information contains fields indicating the PDSCH time and frequency resources and configuration. In this case, the indication process is as follows.

[0227] 1) PDSCH time-domain resource indication:

[0228] Based on the configuration in Table 4, the user terminal uses the Time domain resource assignment field in the MIB as the row index to indicate the length of the PDSCH time domain resource symbol in the following table.

[0229] Table 4: PDSCH Time Domain Resource Allocation

[0230] row index Symbol length L 0 7 1 6 2 4 3 3

[0231] It should be noted that the scenario diagram for the third type of MIB shows the following SSB time-domain distribution: starting from the first complete time slot after the current wave position dwell time begins, there is one SSB in every half time slot, and the duration of each half time slot is 2 seconds. -μ-1 ms. SSB n The duration is 4 symbols, which is The time difference T between SSB and the start time of half a time slot SSB_offset This is a pre-agreed, fixed configuration.

[0232] It should be noted that in this scenario, when OFDM (Orthogonal Frequency Division Multiplexing) symbols use a cyclic prefix (Normal CP), the SSB... n The duration is

[0233] like Figure 4 As shown, the starting time of the dwell time of the i-th wave position is i*T. b If the dwell time of this wave position supports N SSBs, then the start time of the nth SSB is i*T. b +n*2 -μ-1 +T SSB_offset , n∈{0,1,…,N-1}ms. Where,

[0234] Specifically, the channel layout diagram corresponding to the SIBx messages associated with each SSB is as follows: Figure 5 and Figure 6 As shown, Figure 5 For SSB and PDSCH frequency division multiplexing of MIB type 3, Figure 6 Time-division multiplexing of SSB and PDSCH for MIB type 3. For example... Figure 4 and Figure 5 As shown, during the i-th dwell time, if The PDSCH corresponding to the nth SSB is from i*T b +n*2 -μ-1 +T PDSCH_offset The process begins with n∈{0,1,…,N-1}ms. Where 1 / (2 μ *14) In this context, 14 represents 14 symbols per slot, and L is the symbol length. In this scenario, a first resource set is configured for every half slot, hence T SSB_offset T is the time difference between the start time of the SSB and the half-slot time interval. PDSCH_offset This is the time difference between PDSCH and the start time of half a time slot.

[0235] It should be noted that in this scenario, when the OFDM symbol uses Normal CP, one slot corresponds to 14 symbols, which is equivalent to half the length of one time slot. μ ms, 1 symbol length 1 / (2 μ *14)ms.

[0236] like Figure 4 and Figure 6 As shown, during the i-th dwell time, if The PDSCH corresponding to the nth SSB is from i*T b +n*2 -μ-1 The process begins with n∈{0,1,…,N-1}ms;

[0237] 2) PDSCH time-domain resource indication:

[0238] Its frequency domain starting resource block (RB) is the least common RB index of the last RE in the synchronization signal / physical broadcast channel (SS / PBCH) block plus one. The length of the frequency domain RB is indicated by the Frequency domain resource assignment field in the MIB. Here, RE (Resource Element) is the smallest resource unit in NR physical resources; it occupies 1 Symbol in the time domain and 1 subcarrier in the frequency domain. The symbols commonly referred to, i.e., the modulated data symbols, are mapped to RE.

[0239] 3) PDSCH time-domain resource indication:

[0240] After the terminal decodes and learns the Modulation and coding scheme field in the MIB, it uses it as a row index to indicate the code rate and modulation order of the PDSCH. The specific parameters are shown in Table 5.

[0241] Table 5. MCS Index Table of PDSCH

[0242]

[0243]

[0244] 4) PDSCH interleaving mapping method: The terminal determines the interleaving mapping method according to a pre-agreed fixed value.

[0245] (3) Obtain PRACH configuration information: After the terminal obtains the time and frequency position, code rate, modulation order, interleaving mapping method and other parameters of the PDSCH, the terminal demodulates the PDSCH channel to obtain SIBx information and obtains the configuration parameters of the PRACH channel.

[0246] (4) Initiating uplink random access: Finally, the terminal sends a PRACH channel on the corresponding random access occasion to perform cell search and initiate uplink random access.

[0247] like Figure 7 As shown, this embodiment of the invention also provides an information sending device, including:

[0248] The transmitting module 10 is used to transmit N first resource sets within one wavelength dwell time of the first beam; the wavelength dwell time is the time required for any wavelength in the first beam to dwell.

[0249] Wherein, N is an integer greater than or equal to 0; the first resource set includes: the minimum combination of channels and signals required for any terminal to complete cell search.

[0250] Optionally, the first resource set includes:

[0251] Synchronization signal and physical broadcast channel block (SSB);

[0252] or,

[0253] SSB and Physical Downlink Shared Channel (PDSCH);

[0254] or,

[0255] SSB, PDSCH, and Physical Downlink Control Channel (PDCCH).

[0256] Optionally, the SSB includes a primary synchronization signal PSS, a secondary synchronization signal SSS, a physical broadcast channel PBCH, and a demodulation reference signal DMRS;

[0257] Among them, PSS and SSS are used for downlink time-frequency synchronization and to carry cell ID information; PBCH scrambling code can carry MIB type information, and PBCH payload carries MIB information; DMRS is used to provide estimation and equalization of the PBCH channel, and to carry index information of the SSB;

[0258] The PDCCH carries downlink control information (DCI) and indicates the channel configuration information of the PDSCH.

[0259] The PDSCH carries the System Information Block (SIBx) information, which includes the necessary information for the terminal to initiate random access.

[0260] Optionally, the MIB type information is used to indicate the MIB type;

[0261] When the MIB type is the first type, the corresponding MIB information includes: pre-set main field information and the first configuration parameter set of the Physical Random Access Channel (PRACH);

[0262] When the MIB type is the second type, the corresponding MIB information includes: preset main field information;

[0263] When the MIB type is the third type, the corresponding MIB information includes: pre-set main field information and PDSCH configuration parameters;

[0264] When the MIB type is the fourth type, the corresponding MIB information includes: pre-set main field information, control resource set CORESET#0 configuration, and search space corresponding information; the CORESET#0 and the search space determine the time-frequency range of the PDCCH;

[0265] The degree of simplicity of the first resource set corresponding to the four MIB types is as follows: MIB type is type 1 > MIB type is type 2 > MIB type is type 3 > MIB type is type 4.

[0266] Optionally, when the MIB type is the second, third, or fourth type, the corresponding SIBx information includes: the second configuration parameter set of PRACH; both the first configuration parameter set of PRACH and the second configuration parameter set of PRACH include:
