[0002] This application relates to the field of communication technology, and in particular to a method, apparatus, medium, product and chip for acquiring parameter information. Background Technology

[0003] Because multiple communication versions exist, adjusting terminal device parameters requires tailoring the settings for users with different versions. However, current parameter adjustment schemes suffer from poor compatibility and numerous constraints during the adjustment process, limiting usability and hindering timely parameter adjustments. Therefore, how to adjust terminal device parameters promptly has become a critical technical problem to be solved. Summary of the Invention

[0004] This application provides a method, apparatus, medium, product, and chip for acquiring parameter information, with the aim of solving the problem of how to adjust the parameters of terminal devices in a timely manner.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] The first aspect of this application provides a method for obtaining parameter information. This method can be executed by a terminal device, or by a component (such as a circuit, chip, or chip system) configured in the terminal device, or by a logic module or software capable of implementing all or part of the terminal device's functions. For example, the method is applied to a first terminal device, but this application does not limit its application. The following description uses a terminal device as an example. The method includes:

[0007] Acquire first information of the primary synchronization signal (PSS) and / or second information of the secondary synchronization signal (SSS); the first information and / or the second information are used to indicate third information; the third information is the parameter information of the terminal device;

[0008] The third information is determined based on the first information and / or the second information.

[0009] In the above scheme, the terminal device determines its parameter information through the first information in the primary synchronization signal and / or the second information in the secondary synchronization signal, so as to adjust the parameter information of the terminal device based on the primary synchronization signal and / or the secondary synchronization signal. Furthermore, since different versions of the terminal device need to search for the primary synchronization signal and / or the secondary synchronization signal when accessing the cell, the parameters of any version of the terminal device can be adjusted, thereby enabling timely adjustment of the parameter information of the terminal device.

[0010] In some possible implementations, the third information includes at least one of the following: the period of the synchronization signal block, the subcarrier spacing, the transmission time interval, the cyclic prefix length, the frame structure, and the waveform. The cyclic prefix (CP) length is used to eliminate inter-symbol interference caused by multipath propagation; different CP lengths affect the system's resistance to multipath fading and its spectral efficiency. The waveform can be a waveform indicator, such as waveform indicators for cyclic prefix orthogonal frequency division multiplexing (CP-OFDM), discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), orthogonal time-frequency-space (OTFS).

[0011] In some possible implementations, the first information is used to indicate the frequency domain position of the synchronization signal block in the synchronization grid of the primary synchronization signal; and / or the second information is used to indicate the frequency domain position of the synchronization signal block in the synchronization grid of the secondary synchronization signal.

[0012] In some possible implementations, determining the third information based on the first information and / or the second information includes:

[0013] The third information is determined based on the first rule and the frequency domain positions of the synchronization signal blocks in the synchronization grid of the main synchronization signal and / or the synchronization signal blocks in the synchronization grid of the auxiliary synchronization signal; the first rule is used to indicate the correspondence between the frequency domain positions of the synchronization signal blocks in the synchronization grid of the main synchronization signal and / or the synchronization signal blocks in the synchronization grid of the auxiliary synchronization signal and the third information.

[0014] In the above scheme, by establishing a first rule, the terminal device can determine the third information based on the first rule, the first information, and / or the second information, so as to realize the timely adjustment of the parameter information of the terminal device.

[0015] In some possible implementations, the first rule includes:

[0016] The first remainder corresponds to the third information; the first remainder is the remainder of the ratio of the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal to the integer number of values ​​of the third information.

[0017] In some possible implementations, the first rule includes:

[0018] The correspondence between the value of the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal and the third information.

[0019] In some possible implementations, the first rule includes:

[0020] The second remainder corresponds to the first sub-information; the second remainder is at least one of the remainders of the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal and the integer ratio of the number of values ​​of the third information.

[0021] The correspondence between the value of the second parameter in the frequency domain position of the synchronization signal block and the second sub-information; the third information includes the first sub-information and the second sub-information.

[0022] In some possible implementations, the first information is used to indicate the sequence of the primary synchronization signal; and / or the second information is used to indicate the sequence of the secondary synchronization signal.

[0023] In some possible implementations, determining the third information based on the first information and / or the second information includes:

[0024] The third information is determined based on the correspondence between the first offset value and the third information, and the first offset value, and / or the correspondence between the second offset value and the third information, and the second offset value; the first offset value is the offset value of the sequence of the main synchronization signal relative to the initial sequence of the main synchronization signal; the second offset value is the offset value of the sequence of the auxiliary synchronization signal relative to the initial sequence of the auxiliary synchronization signal.

[0025] In the above scheme, by establishing a correspondence between the offset values ​​of the sequences of the primary synchronization signal and / or the secondary synchronization signal and the third information, the terminal device can determine the third information based on the correspondence, the first offset value and / or the second offset value, so as to realize timely adjustment of the parameter information of the terminal device.

[0026] In some possible implementations, determining the third information based on the first information or the second information includes:

[0028] In the above scheme, by establishing a correspondence between the sequence group to which the sequence of the main synchronization signal and / or the auxiliary synchronization signal is located and the third information, the terminal device can determine the third information based on the correspondence, the first sequence group and / or the second sequence group, so as to realize timely adjustment of the parameter information of the terminal device.

[0029] In some possible implementations, the first information is used to indicate the location of the resource element of the primary synchronization signal; the second information is used to indicate the location of the resource element of the secondary synchronization signal.

[0030] In some possible implementations, determining the third information based on the first information and the second information includes:

[0031] The third information is determined based on the resource element difference and the correspondence between the resource element difference and the third information; the resource element difference is the amount of resource elements that differ between the resource element position of the primary synchronization signal and the resource element position of the secondary synchronization signal.

[0032] In the above scheme, by establishing a correspondence between the resource element difference between the primary synchronization signal and the secondary synchronization signal and the third information, the terminal device can determine the third information based on the correspondence and the resource element difference, so as to realize timely adjustment of the parameter information of the terminal device.

[0033] In some possible implementations, the first information is used to indicate the transmission time of the primary synchronization signal; the second information is used to indicate the transmission time of the secondary synchronization signal.

[0034] In some possible implementations, determining the third information based on the first information and the second information includes:

[0035] The third information is determined based on the signal transmission interval and the correspondence between the signal transmission interval and the third information; the signal transmission interval is the transmission interval between the primary synchronization signal and the secondary synchronization signal.

[0036] In the above scheme, by establishing a correspondence between the signal transmission intervals of the primary synchronization signal and the secondary synchronization signal and the third information, the terminal device can determine the third information based on the correspondence and the signal transmission interval, so as to realize timely adjustment of the parameter information of the terminal device.

[0037] The second aspect of this application provides a method for obtaining parameter information.

Furthermore, since different versions of terminal devices need to search for the primary synchronization signal and / or secondary synchronization signal when accessing a cell to adjust the parameters of any version of the terminal device, the parameter information of the terminal device can be adjusted in a timely manner.

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0081] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0082] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0083] The embodiments of this application are applied to communication systems, which can be second-generation (2G) communication systems, third-generation (3G) communication systems, LTE systems, fifth-generation (5G) communication systems, LTE and 5G hybrid architectures, 5G new radio (5G NR) systems, and new communication systems that will emerge in the future development of communication.

[0084] The communication system includes a first device and a second device. The first device can be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. Network devices are typically base stations (including functional units of base stations, or combinations of functional units of base stations) or core network units. Core network units can be functional units within the core network, including but not limited to access and mobility management function (AMF) units, session management function (SMF) units, and user plane function (UPF) units. The second device can be a device accessing the network, typically a terminal. An example of a communication system is shown in Figure 1. Figure 1 includes server 1, server 2, and base stations 1, 2, 3, and 4. Server 1 and server 2 have AMF and UPF units. Base stations 1 and 2 are base stations in a new radio architecture, and base stations 3 and 4 are evolved terrestrial base stations. Base stations communicate and transmit data through the Xn interface, and the server and base stations are connected through the NG interface.

[0085] In the embodiments provided in this application, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can include one or more co-located or non-co-located transmission reception points (TRPs). The base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with the terminal, or it can communicate with the terminal through a relay station. The terminal can communicate with multiple base stations using different technologies. For example, the terminal can communicate with base stations that support LTE networks, base stations that support 5G networks, and can also establish dual connections with both LTE and 5G base stations.

[0086] In the embodiments provided in this application, the terminal can take various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The terminal may also be referred to as terminal equipment, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, terminal equipment, wireless communication equipment, UE agent, or UE device, etc. The terminal can also be a fixed terminal or a mobile terminal.

[0087] Since most of the energy consumption of mobile networks comes from the radio access network (RAN), one possible approach to reduce RAN energy consumption is to employ a time-domain dynamic adjustment energy-saving scheme in 3G scenarios. However, this scheme suffers from the problem that the cell-defining-synchronization signal block (CD-SSB) is at the cell level. This means that even if there are no users in the cell, the network still needs to send the synchronization signal block (SSB), thus hindering energy conservation.

[0088] Because 5G network energy saving needs to consider compatibility with existing users, restrictions need to be placed on CD-SSBs and users currently in idle state to avoid affecting their network access. This prevents the time-domain adjustment of the primary cell (PCELL) from taking effect and thus fails to generate energy-saving gains. Therefore, this application provides a parameter information acquisition method, apparatus, medium, product, and chip to acquire parameter information and dynamically adjust the period of the synchronization signal block based on the parameter information, thereby improving the network's energy-saving gains.

[0089] To make the technical solution of this application clearer and easier to understand, the parameter information acquisition method of the embodiments of this application will be described below with reference to the accompanying drawings.

[0090] Referring to Figure 2, a flowchart of a parameter information acquisition method is shown. The method includes:

[0091] S201: Determine the primary synchronization signal and / or the secondary synchronization signal, wherein the primary synchronization signal includes first information; the secondary synchronization signal includes second information; the first information and / or the second information are used to indicate third information; the third information is parameter information of the terminal device.

[0092] Specifically, the network device determines the first information included in the primary synchronization signal and / or the second information included in the secondary synchronization signal based on a pre-established correspondence between the first information and / or the second information and the third information. For example, if the correspondence between the first information and the third information is such that when the first information is a1, the corresponding third information is b1, and when the first information is a2, the corresponding third information is b2, then when the third information is b2, the primary synchronization signal sent by the network device includes the first information with content a2.

[0093] S202: Obtain the first information of the primary synchronization signal and / or the second information of the secondary synchronization signal; the first information and / or the second information are used to indicate the third information; the third information is the parameter information of the terminal device. Accordingly, the network device sends the primary synchronization signal and / or the secondary synchronization signal.

[0094] Specifically, the terminal device receives a primary synchronization signal and / or a secondary synchronization signal sent by the network device to obtain first information and / or second information. The primary synchronization signal carries the first information, which may specifically be information related to the primary synchronization signal. The secondary synchronization signal carries the second information, which may specifically be information related to the secondary synchronization signal. For example, the first information may be any one or more of the following information related to the primary synchronization signal: the frequency domain position of the synchronization signal block in the synchronization grid of the primary synchronization signal, the sequence of the primary synchronization signal, the position of the resource element of the primary synchronization signal, and the transmission time of the primary synchronization signal. The second information may be any one or more of the following information related to the secondary synchronization signal: the frequency domain position of the synchronization signal block in the synchronization grid of the secondary synchronization signal, the sequence of the secondary synchronization signal, the position of the resource element of the secondary synchronization signal, and the transmission time of the secondary synchronization signal.

[0095] The first and / or second information are used to indicate the third information, which is the parameter information of the terminal device. For example, the third information can be at least one of the parameter information of the terminal device, such as the period of the synchronization signal block, the subcarrier spacing, the transmission time interval, the cyclic prefix length, the frame structure, and the waveform.

[0096] Furthermore, this application pre-establishes a correspondence between information related to the primary synchronization signal and / or information related to the secondary synchronization signal and the third information, so as to indicate the third information by making the first information include information related to the primary synchronization signal and / or making the second information include information related to the secondary synchronization signal.

[0097] To facilitate understanding, the following example illustrates how the first piece of information is used to indicate the third piece of information:

[0098] If the correspondence between the information related to the main synchronization signal and the third information is as follows: when the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal is within the first frequency domain position range, it corresponds to the third information A; when the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal is within the second frequency domain position range, it corresponds to the third information B; then when the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal included in the first information is within the first frequency domain position range, the first information is used to indicate the third information A.

[0099] S203: Determine the third information based on the first information and / or the second information.

[0100] Specifically, the specific content of the third information indicated by the first and / or second information is determined, and the specific content indicated by the first and / or second information is used as the third information. For example, when the third information is the period of the synchronization signal block, the third information can be the value of the period; when the third information is a waveform, the third information can be the type of waveform, etc.

[0101] In an optional embodiment, when the first information is used to indicate the frequency domain position of the synchronization signal block in the synchronization grid of the primary synchronization signal, and / or the second information is used to indicate the frequency domain position of the synchronization signal block in the synchronization grid of the secondary synchronization signal, the third information is determined based on the first information and / or the second information, including:

[0102] Based on the first rule and the frequency domain positions of the synchronization signal blocks in the synchronization grid of the main synchronization signal and / or the synchronization signal blocks in the synchronization grid of the auxiliary synchronization signal, the third information is determined; the first rule is used to indicate the correspondence between the frequency domain positions of the synchronization signal blocks in the synchronization grid of the main synchronization signal and / or the synchronization signal blocks in the synchronization grid of the auxiliary synchronization signal and the third information.

[0103] When the information related to the primary synchronization signal is the frequency domain position of the synchronization signal block in the primary synchronization signal grid, and / or the information related to the secondary synchronization signal is the frequency domain position of the synchronization signal block in the secondary synchronization signal grid, the correspondence between the information related to the secondary synchronization signal and / or the information related to the secondary synchronization signal and the third information can specifically be a first rule. The first rule is used to indicate the correspondence between the frequency domain position of the synchronization signal block and the third information, so that the terminal device can determine the third information based on the first rule, the first information and / or the second information.

[0104] Since the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal is the same as that of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal, the third information can be determined based on either the first or the second information, or the third information can be determined based on the first and the second information respectively. The third information determined based on the first information is then compared with the third information determined based on the second information to determine whether the determined third information is consistent. If they are inconsistent, the third information is re-determined based on the first and the second information to improve the accuracy of the determined third information.

[0105] Specifically, the first rule includes:

[0106] The correspondence between the value of the first parameter and the third information in the frequency domain position of the synchronization signal block in the synchronization grid.

[0107] The frequency domain position of the synchronization signal block includes a first parameter, which can be parameter N in the frequency domain position of the synchronization signal block. The first parameter in the frequency domain position of the synchronization signal block in the synchronization grid can be the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal, or the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal.

[0108] The correspondence between the values ​​of the first parameter and the third information is established as follows: based on the number t values ​​of the third information, the number y values ​​of the first parameter are divided equally into t sets. A correspondence is established between these sets and the values ​​of the third information, such that all values ​​of the first parameter in a set correspond to one value of the third information, and each set corresponds to a different value of the third information. The number of values ​​of the third information is the total number of possible values ​​for the third information, and the number of values ​​of the first parameter is the total number of possible values ​​for the first parameter.

[0109] For example, when the number of possible values ​​for the third information is 5 and the number of possible values ​​for the first parameter is 20, the 20 possible values ​​for the first parameter are evenly divided into five sets: the first set, the second set, the third set, the fourth set, and the fifth set. Each set includes four possible values ​​for the first parameter. A correspondence is established between the five sets and the five possible values ​​for the third information, so that each set corresponds to a different possible value for the third information.

[0110] It should be noted that this application can employ any of several partitioning methods to divide the number of values ​​for the first parameter into t equal parts, such that each part of the value resides in one set, resulting in t sets. For example, the values ​​for the first parameter can be arranged in ascending order, and consecutive y values ​​of the first parameter can be assigned to one set, resulting in t sets. Alternatively, the values ​​for the first parameter can be divided into y / t parts, each consisting of t consecutive values ​​in ascending order, and then the t values ​​in each part can be assigned to t sets in ascending order, until all values ​​for the first parameter are assigned to sets. This cyclic partitioning method effectively divides the values ​​of the first parameter into t sets.

[0111] For ease of understanding, this application will use the example of dividing the value of the first parameter into t sets in a cyclical manner to establish the correspondence between the value of the first parameter and the third information for subsequent explanation.

[0112] When establishing the correspondence between the value of the first parameter and the third information using a cyclic partitioning method, the first rule includes:

[0113] The correspondence between the first remainder and the third information; the first remainder is the remainder of the integer ratio of the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal to the number of values ​​of the third information.

[0114] Since this application uses a cyclic partitioning method to establish the correspondence between the value of the first parameter and the third information, the third information indicated by the first information or the second information can be determined based on the first remainder.

[0115] Taking the period of the synchronization signal block as the third information as an example, obtaining the number of values ​​for the third information is equivalent to obtaining the number of values ​​for the period of the synchronization signal block. If the number of values ​​for the period of the synchronization signal block is four, and they are 20 milliseconds, 40 milliseconds, 80 milliseconds, and 160 milliseconds in ascending order, then when the value of the first parameter is divisible by 4 (i.e., the first remainder is 0), the value of the third information corresponding to the first remainder is 20 milliseconds. When the first remainder is 1, the value of the third information corresponding to the first remainder is 40 milliseconds. When the first remainder is 2, the value of the third information corresponding to the first remainder is 80 milliseconds. When the first remainder is 3, the value of the third information corresponding to the first remainder is 160 milliseconds.

[0116] Furthermore, in addition to establishing a correspondence between the values ​​of the first parameter and the third information, this application can also establish a correspondence between the values ​​of the second parameter and the third information. The first rule includes:

[0117] The correspondence between the value of the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid and the third information.

[0118] The frequency domain position of the synchronization signal block in the synchronization grid also includes a second parameter M. The second parameter in the frequency domain position of the synchronization signal block in the synchronization grid can be the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal, or the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal.

[0119] Specifically, the first rule includes:

[0120] The correspondence between the values ​​of the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal and the third information.

[0121] Since the number of possible values ​​for the second parameter is relatively small, establishing a correspondence between the values ​​of the second parameter and the third information is only applicable when the number of possible values ​​for the third information is less than or equal to the number of possible values ​​for the second parameter. A correspondence is established between each possible value of the second parameter and each possible value of the third information, such that each value of the second parameter corresponds to one value of the third information, and each value of the third information has at least one corresponding value of the second parameter.

[0122] For example, if the synchronization grid is as shown in Table 1, then in the frequency range of 0-3000MHz, the second parameter can be selected as 1, 3, or 5, thus the number of possible values ​​for the second parameter is 3. If the third information is the frequency domain position of the synchronization signal block, and the number of possible values ​​is 3, specifically 20 milliseconds, 40 milliseconds, and 80 milliseconds, then when the second parameter is 1, the corresponding value of the third information is 20 milliseconds. When the second parameter is 3, the corresponding value of the third information is 40 milliseconds. When the second parameter is 5, the corresponding value of the third information is 80 milliseconds. If the number of possible values ​​for the third information is 2, specifically 20 milliseconds and 40 milliseconds, then when the second parameter is 1, the corresponding value of the third information is 20 milliseconds. When the second parameter is 3 or 5, the corresponding value of the third information is 40 milliseconds.

[0123] Table 1

[0124] Furthermore, this application can simultaneously establish a correspondence between the value of the first parameter and the third information, as well as a correspondence between the value of the second parameter and the third information. The first rule includes:

[0125] The correspondence between the value of the first parameter and the first sub-information in the frequency domain position of the synchronization signal block in the synchronization grid;

[0126] The correspondence between the value of the second parameter in the frequency domain position of the synchronization signal block in the synchronization grid and the second sub-information; the third information includes the first sub-information and the second sub-information.

[0127] The third information is divided into two sub-information segments: the first sub-information and the second sub-information. The first sub-information includes some of the values ​​of the third information, and the second sub-information includes the remaining values ​​of the third information. A correspondence is established between the values ​​of the first parameter and each value in the first sub-information, and between the values ​​of the second parameter and each value in the second sub-information, so that the value of the third information can be determined using the first and second parameters.

[0128] To facilitate understanding, the following examples illustrate the correspondence between the values ​​of the first parameter and the first sub-information, as well as the correspondence between the values ​​of the second parameter and the second sub-information. The first rule specifically includes:

[0129] The correspondence between the second remainder and the first sub-information; the second remainder is at least one of the remainders of the ratio of the first parameter in the frequency domain position of the synchronization signal block in the synchronization grid of the main synchronization signal and / or the frequency domain position of the synchronization signal block in the synchronization grid of the auxiliary synchronization signal to the integer number of values ​​of the third information.

[0130] The frequency domain position of the synchronization signal block also includes a second parameter, and the value of the second parameter corresponds to the second sub-information; the third information includes the first sub-information and the second sub-information.

[0131] A cyclic partitioning method is used to establish a correspondence between the value of the first parameter and a portion of the third information, and a correspondence between the value of the second parameter and the remaining portion of the third information. When the value of the third information cannot be determined based on the correspondence between the value of the first parameter and a portion of the third information, the value of the third information is determined based on the correspondence between the value of the second parameter and the remaining portion of the third information. Since the remainder of the integer ratio of the number of values ​​of the first parameter and the third information can be any number from 0 to 9, the number of values ​​of the second remainder is within the range of greater than or equal to 1 and less than or equal to 9. This allows the terminal device to determine the value of the third information based on the correspondence between the value of the second parameter and the remaining portion of the third information when the remainder of the integer ratio of the number of values ​​of the first parameter and the third information is a value other than the second remainder.

[0132] For example, when the third information is the period of a synchronization signal block, if the number of values ​​for the period of the synchronization signal block is four (20 milliseconds, 40 milliseconds, 80 milliseconds, and 160 milliseconds), then the sum of the number of values ​​for the first sub-information and the second sub-information is four. Taking the first sub-information values ​​as 20 milliseconds and 40 milliseconds, and the second sub-information values ​​as 80 milliseconds and 160 milliseconds as an example, if the second remainder ranges from 0 to 8, then the correspondence between the second remainder and the first sub-information is as follows: if the second remainder is 0-4, the first sub-information value is 20 milliseconds; if the second remainder is 5-8, the first sub-information value is 20 milliseconds. If the remainder of the integer ratio of the first parameter to the number of values ​​for the third information is 9, then the value of the third information is determined based on the correspondence between the second parameter and the second sub-information. If the second parameter can be 1, 3, or 5, then the correspondence between the value of the second parameter and the second sub-information is as follows: when the second parameter is 1 or 3, the value of the second sub-information is 80 milliseconds; when the second parameter is 5, the value of the second sub-information is 160 milliseconds.

[0133] In an optional embodiment, when the first information is used to indicate the sequence of the primary synchronization signal and / or the second information is used to indicate the sequence of the secondary synchronization signal, the third information is determined based on the first information and / or the second information, including:

[0134] Based on the correspondence between the first offset value and the third information, and the first offset value, and / or the correspondence between the second offset value and the third information, and the second offset value, the third information is determined; the first offset value is the offset value of the sequence of the main synchronization signal relative to the initial sequence of the main synchronization signal; the second offset value is the offset value of the sequence of the auxiliary synchronization signal relative to the initial sequence of the auxiliary synchronization signal.

[0135] Add a first offset value to the sequence of the primary synchronization signal, and / or add a second offset value to the sequence of the secondary synchronization signal. The first and second offset values ​​are integers, and the number of values ​​for the first parameter is the same as the number of values ​​for the second offset and the number of values ​​for the third information, respectively. The initial sequence of the primary synchronization signal is the sequence of the primary synchronization signal when the first offset value is 0, and the initial sequence of the secondary synchronization signal is the sequence of the secondary synchronization signal when the second offset value is 0. Establish a correspondence between the first offset value and the values ​​of the third information, and / or between the second offset value and the values ​​of the third information, so that each value of the first offset value corresponds to one value of the third information, and / or each value of the second offset value corresponds to one value of the third information.

[0136] The master synchronization signal sequence consists of three sequences, and the formula for generating the sequences can be d. OVERLAID (n) = 1 - 2x(m), Where offseti is the first offset value, n ranges from 0 to 126, mod127 indicates that the length of the primitive polynomial of the sequence is 127, x is a function, and 2x(m) takes the value 0 or 1. The primary synchronization signal carries the cell ID. The formula for generating the sequence of the secondary synchronization signal can be... Where offset1 is the second offset value. The cell ID carried by the auxiliary synchronization signal.

[0137] Taking the correspondence between the first offset value and the third information as an example, if the third information is the period of the synchronization signal block, and the period of the synchronization signal block includes 20 milliseconds, 40 milliseconds, 80 milliseconds, and 160 milliseconds, and the first offset value can range from 0 to 3, then the correspondence between the first offset value and the third information can be as follows: when the first offset value is 0, the third information is 20 milliseconds; when the first offset value is 1, the third information is 40 milliseconds; when the first offset value is 2, the third information is 80 milliseconds; and when the first offset value is 3, the third information is 160 milliseconds.

[0138] Specifically, based on the correspondence between the first offset value and the third information, and the first offset value, and / or the correspondence between the second offset value and the third information, and the second offset value, the third information is determined, including:

[0139] The terminal device demodulates the sequences of different primary synchronization signals and / or secondary synchronization signals, and uses the value of the third information corresponding to the first offset value of the demodulated sequence of primary synchronization signals and / or the value of the third information corresponding to the sequence of secondary synchronization signals as the value of the determined third information.

[0140] In this application, the demodulation order of the sequence of the main synchronization signal and / or the sequence of the auxiliary synchronization signal by the terminal device can be set based on actual needs. For example, when the third information is the period of the synchronization signal block, the sequence with the first offset value of 0 is demodulated first. If the demodulation fails, the sequence is demodulated in descending order of the period of the synchronization signal block corresponding to the sequence until the demodulation is successful.

[0141] It should be noted that when the third information is determined based on the correspondence between the first offset value and the third information, and the first offset value, and / or the correspondence between the second offset value and the third information, and the second offset value, the network device may send a primary synchronization signal and / or a secondary synchronization signal.

[0142] If the third information is the period of the synchronization signal block, the above method further includes: after determining the period of the synchronization signal block based on the first and second information, the terminal device obtains the transmission period of the physical broadcast channel (PBCH) so that the terminal device can perform demodulation. The transmission period of the physical broadcast channel may be the same as or different from the transmission period of the primary synchronization signal or the secondary synchronization signal. For example, as shown in Figure 3, taking a period of 20 milliseconds for both the primary and secondary synchronization signals and a period of 20 milliseconds for the physical broadcast channel, the network device demodulates the primary and secondary synchronization signals within the first 20 milliseconds and stores the data within the current period. After determining that the period of the physical broadcast channel is 20 milliseconds, the data of the physical broadcast channel is demodulated.

[0143] In an optional embodiment, when the first information is used to indicate the sequence of the primary synchronization signal and / or the second information is used to indicate the sequence of the secondary synchronization signal, the third information is determined based on the first information and / or the second information, including:

[0144] Based on the correspondence between the sequence group and the third information, as well as the first sequence group and / or the second sequence group, the third information is determined; the first sequence group is the sequence group in which the sequence of the main synchronization signal is located; the second sequence group is the sequence group in which the sequence of the auxiliary synchronization signal is located.

[0145] Based on the number t values ​​of the third information, generate sequences of 3×t primary synchronization signals and / or 3×t secondary synchronization signals. When generating sequences of 3×t primary synchronization signals or 3×t secondary synchronization signals, divide the sequences of primary or secondary synchronization signals into t groups, each group containing 3 sequences of primary or secondary synchronization signals. Similarly, when generating sequences of 3×t primary synchronization signals and 3×t secondary synchronization signals, divide the sequences of 3×t primary synchronization signals into t groups and the sequences of 3×t secondary synchronization signals into t groups, each group containing 3 sequences.

[0146] The formulas for generating the sequences of the primary synchronization signal and the secondary synchronization signal are d. OVERLAID (n) = 1 - 2x(m), Where n ranges from 0 to 126, mod127 indicates that the length of the sequence primitive polynomial is 127, 2x(m) takes the value of 0 or 1, N is the total number of sequences of the main synchronization signal, and INDEX is the sequence number.

[0147] It should be noted that other 127-length sequential primitive polynomials may be used in this application.

[0148] Dividing the total number of primary synchronization signals into two parts, N1 and N2, the formulas for generating the sequences of primary and secondary synchronization signals can also be:

[0149] Where m0 is the number of cyclic shifts of the sequence corresponding to N1, and m1 is the number of cyclic shifts of the sequence corresponding to N2.

[0150] The terminal device detects the sequence group in which the sequence of the primary synchronization signal and / or the sequence of the secondary synchronization signal are located, and determines the value of the third information based on the determined correspondence between the first sequence group and / or the second sequence group and the third information.

[0151] In an optional embodiment, when the first information is used to indicate the physical resource location of the primary synchronization signal and the second information is used to indicate the physical resource location of the secondary synchronization signal, the third information is determined based on the first information and / or the second information, including:

[0152] Based on the physical resource difference and the correspondence between the physical resource difference and the third information, the third information is determined; the physical resource difference is the amount of physical resource difference between the physical resource position of the main synchronization signal and the physical resource position of the auxiliary synchronization signal.

[0153] Physical resource locations include frequency-domain and time-domain resource locations, such as resource element (RE) locations and resource block (RB) locations. A resource block consists of Z resource elements, where Z is an integer and its value can be set based on actual needs, for example, it can be 12. A correspondence is established between physical resource differences and third-party information; for example, different physical resource differences correspond to different values ​​of third-party information, or every e consecutive physical resource differences correspond to one value of third-party information.

[0154] The terminal device detects the physical resource locations of the primary synchronization signal and the secondary synchronization signal to determine the physical resource difference, and then finds the value of the third information corresponding to the determined physical resource difference in the correspondence between the physical resource difference and the third information to determine the third information.

[0155] For ease of understanding, the following example uses physical resource location as the resource element location. When the first information is used to indicate the resource element location of the primary synchronization signal, and the second information is used to indicate the resource element location of the secondary synchronization signal, the third information is determined based on the first and / or second information, including:

[0156] The third information is determined based on the difference in resource elements and the correspondence between the difference in resource elements and the third information. The difference in resource elements is the amount of resource elements that differ between the resource element positions of the main synchronization signal and the resource element positions of the auxiliary synchronization signal.

[0157] If the third piece of information is the period of the synchronization signal block, and the period of the synchronization signal block can be 20 milliseconds, 40 milliseconds, or 80 milliseconds, then the correspondence between the resource element difference and the period of the synchronization signal block is as follows: When the resource element position of the main synchronization signal is the same as the resource position of the auxiliary synchronization signal, that is, when the resource element difference is 0, the period of the synchronization signal block is 20 milliseconds. When the resource element difference is 1 resource element, the period of the synchronization signal block is 40 milliseconds. When the resource element difference is 2 resource elements, the period of the synchronization signal block is 80 milliseconds.

[0158] In an optional embodiment, when the first information is used to indicate the transmission time of the primary synchronization signal and the second information is used to indicate the transmission time of the secondary synchronization signal, the third information is determined based on the first information and / or the second information, including:

[0159] The third information is determined based on the signal transmission interval and the correspondence between the signal transmission interval and the third information; the signal transmission interval is the transmission interval between the main synchronization signal and the auxiliary synchronization signal.

[0160] The primary synchronization signal is transmitted at the same time as the network device, and the secondary synchronization signal is transmitted at the same time as the network device. One or more interval markers are set between the primary and secondary synchronization signals to control the interval length between their transmission times. These interval markers can be symbols or other identifiers capable of generating intervals. A correspondence is established between the signal transmission intervals and third-party information; for example, a correspondence is established between the interval length and the value of the third-party information, or a correspondence is established between the interval markers between the primary and secondary synchronization signals and the values ​​of the third-party information.

[0161] The terminal device detects the transmission interval between the primary synchronization signal and the secondary synchronization signal to determine the signal transmission interval. Then, it searches for the value of the third information corresponding to the determined signal transmission interval in the correspondence between the signal transmission interval and the value of the third information, thus determining the third information.

[0162] For ease of understanding, as shown in Figure 4, where the number of symbols implicitly indicates the interval, and the third information is the period of the synchronization signal block, if the period of the synchronization signal block can be 20 milliseconds or 40 milliseconds, then the correspondence between the signal transmission interval and the third information is as follows: when the signal transmission interval is 1 symbol, the period of the synchronization signal block is 20 milliseconds; when the signal transmission interval is 2 symbols, the period of the synchronization signal block is 40 milliseconds.

[0163] To make the technical solution of this application clearer and easier to understand, the parameter information acquisition method of this application will be explained in detail below in the specific scenario of obtaining the period of the synchronization signal block.

[0164] Referring to Figure 5, a flowchart of a method for obtaining parameter information in a scenario where the period of a synchronization signal block is obtained is shown. The method includes the following steps:

[0165] S501: Determine the primary synchronization signal and / or the secondary synchronization signal, wherein the primary synchronization signal includes first information; the secondary synchronization signal includes second information; the first information and / or the second information are used to indicate the period of the synchronization signal block.

[0166] S502: Obtain the first information of the primary synchronization signal and / or the second information of the secondary synchronization signal. Accordingly, the network device sends the primary synchronization signal and / or the secondary synchronization signal.

[0167] S503: Determine the period of the synchronization signal block based on the first information and / or the second information.

[0168] The terminal device acquires a primary synchronization signal and / or a secondary synchronization signal sent by the network device. The primary synchronization signal carries first information indicating the period of the synchronization signal block, and the secondary synchronization signal carries second information indicating the period of the synchronization signal block. The first information can be any one or more of the following information related to the primary synchronization signal: the frequency domain position of the synchronization signal block in the synchronization grid of the primary synchronization signal, the sequence of the primary synchronization signal, the position of the resource element of the primary synchronization signal, and the transmission time of the primary synchronization signal. The second information can be any one or more of the following information related to the secondary synchronization signal: the frequency domain position of the synchronization signal block in the synchronization grid of the secondary synchronization signal, the sequence of the secondary synchronization signal, the position of the resource element of the secondary synchronization signal, and the transmission time of the secondary synchronization signal.

[0169] Upon receiving the first and / or second information, based on the content indicated by the first and / or second information, the system searches for the period value of the synchronization signal block corresponding to the content indicated by the first and / or second information in the correspondence between the first and / or second information and the period value of the synchronization signal block. By utilizing the primary synchronization signal and / or the secondary synchronization signal, the period of the synchronization signal block is determined, enabling the terminal device to dynamically adjust the period of the synchronization signal block based on the primary synchronization signal and / or the secondary synchronization signal, thereby improving the network's energy-saving gain. The correspondence between the first and / or second information and the period value of the synchronization signal block can be referred to the description related to the correspondence in Figure 1 above.
