[0083] The embodiments in this application are not exhaustive, but merely illustrative of some embodiments, and are not intended to limit the scope of protection of this application. Unless otherwise specified, each step in a particular embodiment can be implemented as an independent embodiment, and the steps can be arbitrarily combined. For example, a solution after removing some steps in a particular embodiment can also be implemented as an independent embodiment, and the order of the steps in a particular embodiment can be arbitrarily interchanged. Furthermore, the optional implementation methods in a particular embodiment can be arbitrarily combined; moreover, the embodiments can be arbitrarily combined, for example, some or all steps of different embodiments can be arbitrarily combined, and a particular embodiment can be arbitrarily combined with the optional implementation methods of other embodiments. In the embodiments of this application, unless otherwise specified or logically conflicting, the terminology and / or descriptions between the embodiments are consistent and can be mutually referenced. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.
[0084] The terminology used in the embodiments of this application is for the purpose of describing specific embodiments only and is not intended to limit the scope of this application.
[0085] In the embodiments of this application, unless otherwise stated, elements expressed in the singular form, such as "a," "an," "the," "the," "the," "the," "the," "the," "this," etc., can mean "one and only one," or "one or more," "at least one," etc. For example, when using articles such as "a," "an," "the," etc. in translation, the noun after the article can be understood as either a singular expression or a plural expression.
[0086] In the embodiments of this application, "multiple" refers to two or more.
[0087] In some embodiments, the terms “at least one of A or B, at least one of A and B”, “one or more”, “a plurality of”, “multiple”, etc., may be used interchangeably.

The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.
[0091] In some embodiments, “including A,” “containing A,” “for indicating A,” and “carrying A” can be interpreted as directly carrying A or indirectly indicating A.

[0099] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, various embodiments of this application can also be applied to structures that replace communication between access network devices, core network devices, or network devices and terminals with communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the structure can also be configured such that the terminal has all or part of the functions of the access network device. Furthermore, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminals (e.g., "sidelink"). For example, uplink channel, downlink channel, etc., can be replaced with sidelink channel, uplink link, downlink link, etc., can be replaced with sidelink link.
[0100] In some embodiments, the terminal may be replaced by an access network device, a core network device, or a network device. In this case, the access network device, core network device, or network device may also be configured to have all or some of the functions of the terminal.

Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G / 6G).
[0113] In some embodiments, the terminal can use the cell synchronization signal to synchronize downlink time and frequency and obtain the Physical Cell Identity (PCID). In New Radio (NR), the Synchronization Signal Block (SSB) includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH).
[0114] In some embodiments, the structure of an SSB can be as shown in Figure 1B. An SSB consists of three parts: PSS, SSS, and PBCH, where the PBCH contains the demodulation reference signal (DM-RS). An SSB has the following characteristics in the time-frequency domain:
[0115] In the time domain: the time domain occupies 4 consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, with PSS in OFDM symbol #0, SSS in symbol #2, and PBCH in symbols #1, #2, and #3, where PBCH contains DM-RS.
[0116] In the frequency domain: an SSB occupies 20 consecutive Physical Resource Blocks (PRBs) in the frequency domain.
[0117] In this system, the PSS and SSS are mapped onto 127 Resource Elements (REs) in the center of PRBs #4 to #15 (a total of 12 PRBs) within their respective OFDM symbols. The 17 REs in these 12 PRBs that are not mapped to PSS or SSS are all mapped to 0. The mappings of PBCH and DM-RS in OFDM symbols #1 and #3 respectively occupy all 240 REs of 20 PRBs, and the mapping in OFDM symbol #2 occupies all 96 REs of the first and last 8 PRBs. Therefore, the total number of REs occupied by the PBCH mapping in an SSB is 576. The center frequencies of PSS / SSS and PBCH are aligned, and they all use the same subcarrier spacing.
[0118] In some embodiments, the synchronization signal of the NR SSB includes a primary synchronization signal PSS and a secondary synchronization signal SSS. The PSS has three sequences, corresponding to three IDs. One PSS corresponds to 336 SSS sequences, and the ID of the SSS is... NR supports a total of 1008 cell identifiers (PCIDs). The ID of each cell is determined by a combination of the PSS sequence and the SSS sequence.
[0119] In some embodiments, the NR PSS sequence is obtained by modulating a 127-length m-sequence with binary phase shift keying (BPSK), and the three PSS sequences are obtained by different cyclic shifts.
[0120] Alternatively, the PSS sequence can be obtained by the following formula: d PSS (n) = 1 - 2x(m). Where, 0 ≤ n < 127.
[0121] Based on the above formula, the cyclic shift positions corresponding to the three PSS sequences are 0, 43, and 86, respectively. The intervals between these three cyclic shifts are relatively large, thus allowing for better differentiation of different PSSs. Since searching for a PSS is the first signal the UE uses in cell search and has no prior information, the number of PSSs is small.
[0122] In some embodiments, the NR SSS sequence is obtained by BPSK modulation of a 127-length Gold sequence, and 336 SSS sequences are obtained by different cyclic shifts.
[0123] Understandably, Gold sequences possess excellent autocorrelation and cross-correlation properties, with the cross-correlation properties being similar to those of m sequences, but their autocorrelation properties are not as good. When using generator polynomials of the same order, the number of Gold sequences generated far exceeds the number of m sequences; therefore, Gold sequences can be used in SSS (Sequential Summarization and Execution System).
[0124] Optionally, the cyclic shift of the SSS sequence and and The correlation can be obtained using the following formula: d SSS (n) = [1 - 2x0((n + m0) mod 127)][1 - 2x1((n + m1) mod 127)], where,
[0125] Based on the above formula, it can be seen that SSS is generated by the cascading of two generator polynomials. Regardless of and As for the value, m0 can only take 9 values: {0, 5, 10, 15, 20, 25, 30, 35, 40}.
[0126] In some embodiments, the SSB is transmitted as a whole each time it is sent. A transmission cycle contains one SSB burst set. Depending on the frequency band deployment and the corresponding sub-carrier spacing (SCS), the number of SSBs in a burst set can be 4, 8, or 64. In actual network deployments, the PSS / SSS is mainly used by the UE to complete time-frequency synchronization, obtain the cell's PCID, and complete some measurements, while the PBCH contains the Master Information Block (MIB) and the physical timing information of the SSB burst sets.
[0127] SSB burst sets are a method of transmitting SSBs using beamforming and beam scanning technologies. A group of multiple SSBs transmitted by a cell in one beam scan (i.e., one round-robin) is called an SSB burst set. SSB burst sets are transmitted periodically. SSB beam scanning and SSB burst sets can be illustrated in Figure 1C.
[0128] In some embodiments, after initial access is completed, the UE only needs to periodically receive PSS / SSS to ensure its time and frequency accuracy and perform simple measurement operations, without the need for network access. Therefore, the UE does not need to frequently receive / decode PBCH. If the SSB sends PSS / SSS and PBCH as a whole each time, it will consume more resources and waste resources and energy.
[0129] Therefore, in some embodiments, the synchronization signals PSS / SSS and PBCH can be semi-decoupled. That is, the PSS / SSS is mapped and transmitted independently, without needing to include the PBCH in the mapping and transmission; this is called a light function SSB. When the PBCH is mapped and transmitted, an associated PSS / SSS must be transmitted, and the UE needs to receive / decode both the PSS / SSS and the PBCH; this is called a full function SSB. In this case, the periods of both the full function SSB and the light function SSB can be extended accordingly, thereby saving resources and energy. However, when both the full function SSB and the light function SSB are transmitted in the same cell, it is necessary to consider how to distinguish between them so that the UE can perform subsequent corresponding steps after detection. For example, for an initial access UE, upon detecting a light function SSB, PBCH decoding may not be required.
[0130] As an example, the transmission of a lightweight SSB that is semi-decoupled from PSS / SSS and PBCH can be shown in Figure 1D. The transmission period of PSS / SSS is T1 (=640ms) and the transmission period of PBCH is T2 (=1280ms).

[0169] In some embodiments, the first information can be sent based on a first period, and the second information can be sent based on a second period; the two can be independent. As an example, as shown in Figure 2B, the first period and the second period can be the same or different.
[0170] In some embodiments, the number of the aforementioned second candidate frequency domain locations may be one or more.
[0171] In some embodiments, the number of the second candidate frequency domain positions may be the same as or different from the number of the first candidate frequency domain positions. It may be that the number of the second candidate frequency domain positions is greater, the number of the first candidate frequency domain positions is greater, or the number of both candidate frequency domain positions is the same; no limitation is made here.
[0172] In some embodiments, the plurality of second candidate frequency domain locations may refer to locations where the aforementioned second information may be transmitted.
[0173] In some embodiments, actual second information may be transmitted at one or more of the plurality of second candidate frequency domain locations.
[0174] In some embodiments, terminal 101 can perform detection and monitoring at multiple second candidate frequency domain locations.
[0175] In some embodiments, the terminal 101 may sequentially detect at multiple second candidate frequency domain positions. If the terminal 101 stays at a second candidate frequency domain position for more than a preset time and still does not detect the second information, the terminal 101 may continue to detect the second information at the next second candidate frequency domain position.
[0176] In some embodiments, the second candidate frequency domain position is different from the first candidate frequency domain position, that is, the second candidate frequency domain position and the first candidate frequency domain position do not overlap in the frequency domain.
[0177] In some embodiments, the first candidate frequency domain position and the second candidate frequency domain position may be defined independently.
[0178] In some embodiments, the first candidate frequency domain location is one or more of the first reference frequency domain location set.
[0179] In some embodiments, the second candidate frequency domain location is one or more of the second reference frequency domain location set.
[0180] Optionally, the aforementioned first reference frequency domain position set can be agreed upon by a protocol. The protocol can specify the granularity / step size of the first reference frequency domain positions in the first reference frequency domain position set, as well as the start and end points of the frequency domain positions in the first reference frequency domain position set (i.e., the first and last first reference frequency domain positions in the set, where the first first reference frequency domain position may refer to the first reference frequency domain position with the lowest frequency in the set, and the last first reference frequency domain position may refer to the first reference frequency domain position with the highest frequency in the set).
[0181] Optionally, the granularity / step size of the first reference frequency domain location set can be different in different frequency bands.
[0182] Optionally, the multiple frequency domain locations in the aforementioned first reference frequency domain location set may be uniformly distributed or non-uniformly distributed.
[0183] Optionally, similar to the first set of reference frequency domain positions described above, the second set of reference frequency domain positions can also be agreed upon by a protocol. The protocol can specify the granularity / step size of the second reference frequency domain positions in the second set of reference frequency domain positions, as well as the start and end points of the frequency domain positions in the second set of reference frequency domain positions (i.e., the first and last second reference frequency domain positions in the set, where the first second reference frequency domain position may refer to the second reference frequency domain position with the lowest frequency in the set, and the last second reference frequency domain position may refer to the second reference frequency domain position with the highest frequency in the set).
[0184] Optionally, the granularity / step size of the second reference frequency domain location set can be different in different frequency bands.
[0185] Optionally, within the same frequency band, the granularity / step size of the first reference frequency domain location set can be the same as or different from the granularity / step size of the second reference frequency domain location set.
[0186] Optionally, the multiple frequency domain locations in the second reference frequency domain location set mentioned above can be uniformly distributed or non-uniformly distributed.
[0187] Optionally, the first reference frequency domain location set and the second reference frequency domain location set can be determined based on different formulas.
[0188] As an example, this can be illustrated in Figures 2C(a)-(d). A first set of candidate frequency domain locations and a second set of candidate frequency domain locations can be defined independently. The first and second candidate frequency domain locations do not overlap in the frequency domain.
[0189] As an example, first and second candidate frequency domain position sets can be defined independently, as shown in Figure 2C(a). The starting point, ending point, and step size of the first and second candidate frequency domain position sets can be defined independently, respectively. The highest frequency candidate position in the first candidate frequency domain position set is lower than the lowest frequency candidate position in the second candidate frequency domain position set. For example, the frequency of the starting point of the second candidate frequency domain position set can be defined as higher than the frequency of the ending point of the first candidate frequency domain position set.
[0190] As another example, the first and second candidate frequency domain position sets can also be defined independently, as shown in Figure 2C(b). The starting point, ending point, and step size of the first and second candidate frequency domain position sets can be defined independently, respectively. The first and second candidate frequency domain positions in the figure are spaced apart in the frequency domain, with one second candidate frequency domain position between every two adjacent first candidate frequency domain positions. For example, the step size of the first and second candidate frequency domain position sets can be defined to be the same, and the frequency interval between the starting points of the first and second candidate frequency domain position sets can be equal to half of this step size.
[0191] As another example, the first and second candidate frequency domain position sets can also be defined independently, as shown in Figure 2C(c). The starting point, ending point, and step size of the first and second candidate frequency domain position sets can be defined independently, respectively. The first and second candidate frequency domain positions in the figure are distributed at intervals in the frequency domain, with one second candidate frequency domain position between every two adjacent first candidate frequency domain positions. For example, the step size of the first candidate frequency domain position set can be defined to be the same as the step size of the second candidate frequency domain position set, and the frequency interval between the starting points of the first and second candidate frequency domain position sets can be less than half of this step size.
[0192] As another example, the first and second candidate frequency domain position sets can also be defined independently, as shown in Figure 2C(d). The first and second candidate frequency domain positions in the figure are distributed in the frequency domain according to their own patterns and do not overlap.
[0193] In some embodiments, the first candidate frequency domain position and the second candidate frequency domain position may be defined based on a set of reference frequency domain positions.
[0194] In some embodiments, the first candidate frequency domain position is a first subset of the third reference frequency domain position set, and the second candidate frequency domain position is a second subset of the third reference frequency domain position set. Neither the first nor the second subset contains the same third reference frequency domain position. It is understood that the first and second subsets combined can be equal to a subset of the third reference frequency domain position set.
[0195] That is, in the above embodiments, a portion of the reference frequency domain locations can be selected as the first candidate frequency domain locations from the third reference frequency domain location set, and another portion can be selected as the second candidate frequency domain locations, with the two portions not overlapping. It is also possible that a portion of the third reference frequency domain locations are neither selected as the first candidate frequency domain locations nor as the second candidate frequency domain locations.
[0196] Optionally, the aforementioned set of third reference frequency domain positions can be agreed upon by a protocol. The protocol can specify the granularity / step size of the third reference frequency domain positions in the set, as well as the start and end points of the frequency domain positions in the set (i.e., the first and last third reference frequency domain positions in the set, where the first third reference frequency domain position may refer to the third reference frequency domain position with the lowest frequency in the set, and the last third reference frequency domain position may refer to the third reference frequency domain position with the highest frequency in the set).
[0197] Optionally, the aforementioned third reference frequency domain location set can be determined based on the Global Synchronization Channel Number (GSCN) or the Global Channel Grid (also known as the Absolute Radio Frequency Channel Number, ARFCN).
[0198] Optionally, the granularity / step size of the third reference frequency domain location set can be different in different frequency bands.
[0199] In some embodiments, the lowest frequency position in the first subset may be higher than the highest frequency position in the second subset. Alternatively, the highest frequency position in the first subset may be lower than the lowest frequency position in the second subset. As an example, this can be shown in Figure 2D(a).
[0200] In some embodiments, the first candidate frequency domain position and the second candidate frequency domain position may have the same step size, which may be a positive integer multiple of the step size of the third reference frequency domain position.
[0201] Optionally, a second candidate frequency domain position may be included between two adjacent first candidate frequency domain positions. As an example, this can be shown in Figure 2D(b). That is, the step size of both the first and second candidate frequency domain positions is equal to twice the step size of the third reference frequency domain position.
[0202] Optionally, between two adjacent first candidate frequency domain positions, there may also be a second candidate frequency domain position and at least one third reference frequency domain position that does not belong to the first subset or the second subset. As an example, as shown in Figure 2D(c), the step size of both the first candidate frequency domain position and the second candidate frequency domain position is equal to 3 times the step size of the third reference frequency domain position.
[0203] In some embodiments, the first candidate frequency domain position and the second candidate frequency domain position are selected from the third reference signal set according to their respective rules. As an example, this can be shown in (d) of Figure 2D.
[0204] Optionally, between two adjacent first candidate frequency domain positions, there are multiple second candidate frequency domain positions.
[0205] Optionally, between two adjacent first candidate frequency domain locations, there are multiple second candidate frequency domain locations, and at least one third reference frequency domain location that does not belong to the first subset or the second subset.
[0206] Optionally, between two adjacent second candidate frequency domain locations, there are multiple first candidate frequency domain locations.
[0207] Optionally, between two adjacent second candidate frequency domain positions, there are multiple first candidate frequency domain positions and at least one third reference frequency domain position that does not belong to the first subset or the second subset.
[0208] In some embodiments, one of the aforementioned first candidate frequency domain position and the aforementioned second candidate frequency domain position may be defined based on the other of the two and an offset. The other candidate frequency domain position may be one or more from a set of reference frequency domain positions.
[0209] That is, the first candidate frequency domain position can be defined based on the second candidate frequency domain position and offset. Alternatively, the second candidate frequency domain position can be defined based on the first candidate frequency domain position and offset.
[0210] It is understood that the aforementioned reference frequency domain location set can be any one of the first reference frequency domain location set, the second reference frequency domain location set, and the third reference frequency domain location set in the foregoing embodiments, or it can be a reference frequency domain location set defined based on other rules, which is not limited here.
[0211] It is understood that in various embodiments of this application, the reference frequency domain location set is a set of multiple frequency domain locations predefined based on certain rules, and one or more of them can be selected as candidate frequency domain locations in various embodiments of this application.
[0212] In some embodiments, one or more frequency domain locations from the above-mentioned set of reference frequency domain locations may be selected as the first candidate frequency domain location or the second candidate frequency domain location.
[0213] Optionally, the aforementioned offset can be used to indicate the frequency interval between the first candidate frequency domain position and the second candidate frequency domain position within each candidate frequency domain position group.
[0214] Optionally, each candidate frequency domain location group may include a first candidate frequency domain location and a second candidate frequency domain location. As an example, this can be shown in Figure 2E(a).
[0215] Alternatively, each candidate frequency domain location group may include one first candidate frequency domain location and two second candidate frequency domain locations. As an example, this can be illustrated in Figure 2E(b).
[0216] Alternatively, each candidate frequency domain location group may include two first candidate frequency domain locations and one second candidate frequency domain location. As an example, this can be shown in Figure 2E(c).
[0217] Understandably, for each candidate frequency domain position group, which includes a first candidate frequency domain position and a second candidate frequency domain position, the offset can be either the offset of the first candidate frequency domain position relative to the second candidate frequency domain position within each group, or the offset of the first candidate frequency domain position relative to the second candidate frequency domain position within each group. This offset can be towards higher frequencies (e.g., the offset value is positive) or towards lower frequencies (e.g., the offset value is negative).
[0218] For each candidate frequency domain location group, which includes one first candidate frequency domain location and two second candidate frequency domain locations, the offset is the shift of the first candidate frequency domain location within each group relative to the second candidate frequency domain locations. This offset includes shifts towards higher and lower frequencies (e.g., the offset is the absolute value of the frequency difference between the two).
[0219] For each candidate frequency domain location group comprising two first candidate frequency domain locations and one second candidate frequency domain location, the offset is the shift of the first candidate frequency domain location within each group relative to the second candidate frequency domain location. This offset includes shifts towards higher and lower frequencies (e.g., the offset is the absolute value of the frequency difference between the two).
[0220] Optionally, the aforementioned offset can be used to indicate the frequency interval between the first candidate frequency domain location set and the second candidate frequency domain location set. The first candidate frequency domain location set includes multiple first candidate frequency domain locations, and the second candidate frequency domain location set includes multiple second candidate frequency domain locations.
[0221] Optionally, the frequency interval between the first candidate frequency domain location set and the second candidate frequency domain location set can be any of the following:
[0222] The frequency interval between the lowest frequency position in the first candidate frequency position set and the lowest frequency position in the second candidate frequency position set; as an example, it can be shown in (d) of Figure 2E.
[0223] The frequency interval between the highest frequency position in the first candidate frequency position set and the highest frequency position in the second candidate frequency position set; as an example, it can be shown in (e) of Figure 2E.
[0224] The frequency interval between the lowest frequency position in the first candidate frequency position set and the highest frequency position in the second candidate frequency position set; as an example, it can be shown in (f) of Figure 2E.
[0225] The frequency interval between the highest frequency position in the first candidate frequency position set and the lowest frequency position in the second candidate frequency position set. As an example, it can be shown in (g) of Figure 2E.
[0226] In some embodiments, the offset may be defined based on absolute frequency or determined based on frequency domain resource units (e.g., subcarriers, resource blocks, physical resource blocks, etc. under a specific subcarrier spacing).
[0227] In various embodiments of this application, optionally, when there are multiple first candidate frequency domain positions, the interval between two adjacent first candidate frequency domain positions may be the same or different.
[0228] In various embodiments of this application, optionally, when there are multiple second candidate frequency domain positions, the interval between two adjacent second candidate frequency domain positions may be the same or different.
[0229] It is understandable that if the intervals between two adjacent frequency domain positions are the same, then these frequency domain positions can be considered to be uniformly distributed. If the intervals between two adjacent frequency domain positions are different, then these frequency domain positions can be considered to be non-uniformly distributed.
[0230] Additionally, it should be noted that in this embodiment, terminal 101 may receive only the first information, or only the second information, or both the first and second information, or neither the first nor the second information.
[0231] In some embodiments, the above "do not receive" can also be replaced with "do not expect to receive".
[0232] In some embodiments, network device 102 may send only the first information, only the second information, or both the first and second information.

[0297] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0298] The following is an exemplary description of the methods described in the above embodiments.
[0299] In some embodiments, the reference frequency domain location may include at least one of the following:
[0300] 1. Global Channel Grid
[0301] The global channel grid serves as the basic radio frequency reference location. Each frequency point is uniformly numbered using the global grid granularity / step size, corresponding to an NR-ARFCN (Absolute Frequency Channel Number). The global channel grid is the foundation for describing the NR channel grid. Relevant parameters are shown in Table 1 below.
[0302] Table 1. NR-ARFCN parameters of the global frequency raster.
[0303] 2. NR channel grid ΔF Raster
[0304] Based on the aforementioned global channel grid, the 5G NR channel grid specifies the granularity / step size, as well as the start and end points of the channel grid for each deployed frequency band. The 0–3000MHz band includes multiple LTE refarmed bands, requiring consideration of NR and LTE system compatibility. Except for band 41, the granularity / step size of the channel grid for all bands is 100kHz (20 ΔF). Global The frequency bands above 3000MHz are all NR system bands. The channel grid of each band is defined by an integer multiple of the subcarrier spacing, i.e., 2u times ΔF. Global .
[0305] The global channel grid is the NR channel grid ΔF Raster Granularity.
[0306] 3. Globally synchronized grid
[0307] 5G NR defines the "Global Synchronization Grid" as the basic frequency domain granularity for constructing the actual "NR Synchronization Grid". Each Global Synchronization Grid corresponds to a "Global Synchronization Grid Number (GSCN)" in the frequency domain. The parameters are shown in Table 2 below.
[0308] Within the 0–3000MHz range, the granularity of the global synchronization grid is 1.2MHz. An additional ±100kHz offset is added for NR refarming of LTE bands. The distance between the center frequency of the synchronization signal and the center frequency of the cell is an integer multiple of the SCS, which is beneficial for unified FFT processing of the synchronization signal and the data channels on its symbols.
[0309] Within the range of 3000MHz to 24250MHz, the granularity of the global synchronization grid is 1.44MHz.
[0310] Within the range of 24250MHz to 100000MHz, the granularity of the global synchronization grid is 17.28MHz.
[0311] Table 2. GSCN parameters of the global frequency raster.
[0312] 4. NR Synchronization Grid
[0313] Based on the global synchronization grid planning, the corresponding NR synchronization grid positions on each frequency band can be determined. For the vast majority of frequency bands, there is a one-to-one correspondence between the NR synchronization grid positions and the global synchronization grid positions within that band. In addition, for some frequency bands such as n41 and n79, in order to further reduce the complexity of cell search, the NR synchronization grid granularity of the band is multiplied on top of the global synchronization grid.
[0314] The sparsity of the synchronization grid depends primarily on two factors: the SSB bandwidth and the system minimum bandwidth. A larger minimum channel bandwidth or a smaller synchronization signal bandwidth allows for a more sparse synchronization grid design. The synchronization grid is determined by the following formula:
[0315] Synchronization channel grid = minimum channel bandwidth - SSB bandwidth + channel grid.
[0316] The Global Synchronization Grid (GSCN) is the granularity of the NR Synchronization Grid.
[0317] In some embodiments, the network side (base station) sends first information and second information. The first information and the second information correspond to different frequency domain positions.
[0318] In some embodiments, the first information described above possesses at least one of the following features:
[0319] a) The first information carries the synchronization signal and the first system message.
[0320] Optionally, the aforementioned synchronization signal includes at least one signal generated from a sequence, each signal being obtained by modulating and cyclically shifting a ZC sequence, m sequence, or Gold sequence of length N (N>0).
[0321] Optionally, the aforementioned first system message includes the most important basic information from the network side.
[0322] b) The first message is sent according to the first cycle.
[0323] Optionally, the first period is a positive integer, and its value includes, but is not limited to, {5, 10, 20, 40, 80, 160, 320, 640, 1280} milliseconds.
[0324] In some embodiments, the second information described above possesses at least one of the following features:
[0325] a) The second information carries at least one of a synchronization signal and a second system message;
[0326] Optionally, the payload of the second system message is less than or equal to the payload of the first system message.
[0327] b) The second information is sent according to the second period, which is a positive integer and includes, but is not limited to, {5, 10, 20, 40, 80, 160, 320, 640, 1280} milliseconds.
[0328] In some embodiments, when the network side sends the first information and the second information, it may perform at least one of the following actions:
[0329] a) The network side sends the first information and the second information, which are sent at different frequency domain locations.
[0330] Optionally, the first information and the second information can be used to calculate the frequency domain position of the transmitted information respectively:
[0331] One possible approach is to define a synchronization grid, where the frequency domain positions of the first and second information are located on different grids.
[0332] As another possible approach, two sets of grids are defined: a first information grid and a second information grid. These two grids do not overlap.
[0333] Optionally, the frequency domain position of the first information or the second information can be defined, and the frequency domain position of the second information or the first information can be obtained through the frequency domain position of the first information or the second information.
[0334] One possible approach is to define a first synchronization grid, on which the first / second information is located. The offset of the second synchronization grid from the first synchronization grid is defined by an offset, on which the other information is located.
[0335] Furthermore, Offset can be defined as (second synchronization grid - first synchronization grid) or (first synchronization grid - second synchronization grid), with the positive or negative sign indicating a position in a higher or lower frequency domain.
[0336] Alternatively, the Offset can be defined as |Second Synchronization Grid - First Synchronization Grid| (the absolute value of the frequency difference between the two), or |First Synchronization Grid - Second Synchronization Grid|. That is, there may be one second synchronization grid at a high frequency position and one at a low frequency position of the first synchronization grid.
[0337] In some embodiments, the terminal can receive first information and / or second information at various possible frequency domain locations based on frequency domain location information.
[0338] Optionally, the terminal can calculate the frequency domain positions of the first information and the second information respectively.
[0339] Optionally, the terminal can also calculate the frequency domain position of one type of information and deduce the frequency domain position of the other type of information.
[0340] In some embodiments, when the terminal receives the first information and the second information, it performs at least one of the following actions:
[0341] The terminal receives the first information and the second information;
[0342] The terminal only receives the first piece of information and does not receive the second piece of information;
[0343] The terminal does not receive the first information, but directly receives the second information;
[0344] The terminal does not receive the first information, nor does it receive the second information.
[0345] As an example, as shown in Figure 2B, the network sends first information and second information. The first information is sent according to a first cycle, and the second information is sent according to a second cycle.
[0346] As an example, as shown in Figure 2D, a synchronization grid (the third reference frequency domain location set in the foregoing embodiments of this application) can be defined in the frequency domain, and its frequency domain location is shown by the horizontal line in the figure.
[0347] As shown in Figure 2D(a), the synchronization grid consists of a first signal synchronization grid and a second signal synchronization grid. The first and second signal synchronization grids are divided into groups. Each group contains one type of synchronization signal grid.
[0348] As shown in Figure 2D(b) and (c), the first / second signal synchronization grids can be evenly distributed on the synchronization grid. In (b), the step of the first / second information synchronization grid is 2. As shown in the figure, the black first signal synchronization grid (i.e., the first candidate frequency domain position in the aforementioned embodiment of this application) is taken one every other grid on the synchronization grid, and the gray second signal synchronization grid (i.e., the second candidate frequency domain position in the aforementioned embodiment of this application) is also taken one every other grid. The first signal synchronization grid and the second signal synchronization grid do not overlap. In (c), the step of the first / second signal synchronization grid is 3, so not all synchronization grids are ultimately mapped to the first / second signal synchronization grid. As shown in Figure (c), the dotted horizontal line represents the synchronization grid that was not mapped to the first / second signal synchronization grid.
[0349] As shown in Figure 2D(d), the first signal synchronization grid and the second signal synchronization grid can also be distributed on the synchronization grid according to their respective rules.
[0350] As an example, it can be shown in Figures 2C(a)-(d). The difference between the embodiment in Figure 2C and the embodiment in Figure 2D is that the embodiment in Figure 2C does not define a synchronization grid, but directly defines a first information synchronization grid and a second information synchronization grid. The first and second information synchronization grids do not overlap in the frequency domain.
[0351] Optionally, the first / second information synchronization grid can be uniform or non-uniform.
[0352] As an example, it can be shown in Figure 2E. First, the channel synchronization grid of one signal is determined, and then the synchronization grid position of another signal is obtained through offset. The figure takes the determination of the synchronization grid of the first signal as an example (the synchronization grid of the second signal can also be determined first).
[0353] In (a), the second signal synchronization grid is offset from the first signal synchronization grid, and the frequency of the second signal synchronization grid is lower than that of the first signal synchronization grid, or vice versa.
[0354] In (b), the second signal synchronization grid is offset from the first signal synchronization grid, and the frequency of the second signal synchronization grid includes grids that are higher and lower than the first signal synchronization grid, as shown by the green grid.
[0355] In (c), the first signal synchronization grid is defined in the form of a group, and the difference between the second signal synchronization grid group and the first signal synchronization grid group is the group offset. This offset can be defined as the difference between the lowest and highest grid positions within the group.
[0356] Optionally, the value of offset can be defined by absolute frequency.
[0357] In some embodiments, unless contradictory, the optional implementations in this embodiment can be implemented as independent embodiments, and the optional implementations in this embodiment can also be combined arbitrarily. The technical features of different feasible implementations in this embodiment can be combined to form new optional implementations based on their inherent logical relationships.
[0358] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0359] This application also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed, which includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0360] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0361] In this application embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
