[0057] To facilitate a clearer understanding of the technical solutions provided by the embodiments of this application, some relevant background knowledge is introduced as follows.

[0058] (1) Synchronization signal and Physical Broadcast Channel (PBCH);

[0059] To enable a User Equipment (UE) to search for a reasonable cell and synchronize with the selected cell, the network usually needs to broadcast synchronization signals and provide certain primary information about the cell. The synchronization signals mainly include the primary synchronization signal and the secondary synchronization signal. The Physical Broadcast Channel (PBCH) carries the most important system information, also known as the Master Information Block (MIB).

[0060] Figure 2 is a schematic diagram of the structure of the Synchronization Signal Block (SSB) in the related art. In 5G, the structure of the SSB is as Figure 2 shown.

[0061] (2) The mapping rule of the SSB to the Physical Random Access Channel Transmission Opportunity (PRACH Occasion, RO) in 5G NR;

[0062] The Physical Random Access Channel (PRACH) resources and the configuration parameters of the SSB-RO are configured in System Information Block (SIB) 1. In NR, a cell can configure multiple Frequency Division Multiplexing (FDM) PRACH Transmission Occasions (i.e., ROs) at a time domain position for transmitting the PRACH. At a certain moment, the number of ROs that can perform FDM can be: {1, 2, 4, 8}, which is configured and determined by the higher layer parameter Msg1-FDM.

[0063] The Random Access Preamble can only be transmitted on the time domain resources configured by the parameter Physical Random Access Channel Configuration Index (PRACHConfigurationIndex) and the frequency domain resources configured by the parameter Msg1-FDM. The PRACH frequency domain resource n RA ∈ {0, 1,..., M - 1}, where M is equal to the higher layer parameter Msg1-FDM. At the initial access, the PRACH frequency domain resource n RA is numbered in ascending order starting from the RO resource with the lowest frequency in the initial active uplink bandwidth part, otherwise, the PRACH frequency domain resource n RA is numbered in ascending order starting from the RO resource with the lowest frequency in the active uplink bandwidth part. Figure 3 is one of the schematic diagrams of the SSB and RO in the time domain and frequency domain in the related art. For example, in Figure 3Among them, the number of ROs for a moment of FDM is 8 (Msg1-FDM = 8), and the RO resources are numbered RO#0 to RO#7 in ascending order of frequency.

[0064] In NR, there is an association relationship between RO and the actually transmitted SSB. ROs are associated with SSBs in the order of frequency domain (from low frequency to high frequency) first and then time domain. One SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with one RO (in this case, different SSBs correspond to different Preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB: for example, oneEighth means that one SSB is associated with 8 consecutive ROs, eight means that 8 SSBs are associated with one RO, and {n4, n8, n12,...} represents the number of Preambles associated with each SSB on one RO. For example, when the value is n4, it means that the number of Preambles associated with each SSB on one RO is 4, and n8 means that the number of Preambles associated with each SSB on one RO is 4.

[0065] After all SSBs are associated with ROs in one round, it forms an SSB-RO mapping cycle. The association period from one SSB to ROs may contain one or more SSB-RO mapping cycles. The association pattern period from one SSB to ROs may contain one or more SSB-RO association periods, and the mapping from SSB to RO is repeated in the association pattern period, and the maximum association pattern period is 160 ms.

[0066] Generally, the base station can use different beams to transmit different SSBs, and the number of SSBs is configured through the ssb-PositionsInBurst parameter. For Frequency Range (FR) 2, the maximum number of SSBs is 64. The UE selects the RO / "RO and Preamble combination" associated with the SSB with good signal according to the intensity of the received downlink beam / SSB to send Msg1. In this way, the network can determine the SSB selected by the UE according to the RO / "RO and Preamble combination" of the received Preamble, and send Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0067] With Figure 3For example, the number of ROs of FDM at a moment is 8, and the number of actually transmitted SSBs is 4, namely SSB#0, SSB#1, SSB#2, SSB#3, and each SSB is associated with 2 ROs. If the UE determines to send a PRACH / Msg1 on the RO corresponding to SSB#0, then the UE selects one of RO#0 and RO#1 to send the PRACH.

[0068] Figure 4 It is a schematic diagram of the mapping from SSB to RO in the frequency domain in the related art. The following Figure 4 For example, the number of ROs of FDM at a moment is 2, and the number of actually transmitted SSBs is 8, namely SSB#0, SSB#1, ……, SSB#7, and every 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the Preamble sets associated with these multiple SSBs are different, that is, the same Preamble cannot belong to the Preamble sets associated with different SSBs at the same time: Taking Figure 4 RO#0 in it as an example, RO#0 has a total of 60 Preambles, among which the Preambles with indexes from 0 to 29 are associated with SSB#0, and the Preambles with indexes from 30 to 59 are associated with SSB#1.

[0069] It should be noted that Figure 4 each square in it represents an RO, rather than an SSB. The marked SSB refers to which SSB or SSBs this RO is associated with.

[0070] Before the UE sends a PRACH, it first selects the SSB with an RSRP (Reference Signal Received Power) higher than the threshold according to the received reference signal received power of the beam (SSB); if the RSRPs of multiple SSBs are higher than the threshold, the UE can select any SSB with an RSRP higher than the threshold; when there is no SSB with an RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0071] Based on the configuration of the network (NW), the UE obtains the corresponding relationship between the SSB and the RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending the PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of them to send the PRACH / Preamble / Msg1.

[0072] In Figure 3 In the example shown, assuming the UE selects SSB#1, the UE can select one of RO#2 and RO#3 to send the PRACH / Msg1; inFigure 4 In the example shown, if the UE selects SSB#1, the UE can select the available RO (RO#0 or 4) associated with SSB#1 that is closest to the current time for PRACH / Msg1 transmission. Among the selected ROs, the UE selects a preamble from the preamble set associated with the selected SSB for PRACH transmission. As Figure 4 shown, if one RO is associated with 2 SSBs, then in the available preamble set associated with the SSBs in one RO, the preambles are divided into two subsets, each subset corresponding to one SSB. The UE will select a certain preamble sequence from the preamble subset corresponding to the selected SSB for PRACH / Msg1 transmission.

[0073] (3) Determination of the RO set during PRACH retransmission;

[0074] PRACH retransmission is introduced in Rel-18 to enhance uplink coverage. For PRACH retransmission, the UE needs to retransmit the preamble on multiple ROs at different time domain positions associated with the same SSB, and the number of retransmissions can be {2, 4, 8}. After the UE determines the PRACH retransmission count, it needs to determine the RO set, and the number of valid ROs in the RO set is equal to the PRACH retransmission count. Assume the PRACH retransmission count is N1, and the determination rule for the RO group is: First, determine the starting RO of the RO group, and then determine the remaining N1 - 1 ROs of the RO group. The remaining N1 - 1 ROs of each RO group are the ROs that are associated with the same SSB as the starting RO, at the same frequency position, and have the same associated preamble set. For example, Figure 5 is the second schematic diagram of SSB and RO in the time domain and frequency domain in the related art. Next, Figure 5 in the following, assume the PRACH retransmission count is 2. For SSB#0, the RO group can be determined as the four groups of RO groups marked by the shaded part in the figure.

[0075] Next, in combination with the accompanying drawings, the resource mapping method, terminal, and network-side device provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0076] The resource mapping method provided by the embodiments of the present application can be applied to a terminal, and the terminal determines the mapping between the reference object and the access resource and performs corresponding transmission.

[0077] Figure 6 is the first flowchart of the resource mapping method provided by the embodiments of the present application. AsFigure 6 As shown in Figure 6 , the method includes step 601 and step 602; where:

[0078] Step 601, the terminal determines the mapping between the reference object and the access resource; where the mapping is related to the resource mapping information of at least one of the reference object and the access resource, and the resource mapping information includes at least one of a mapping period, an association period, a time period, and a mapping number.

[0079] Step 602, the terminal performs the transmission of at least one of the reference object and the access resource based on the mapping.

[0080] It should be noted that the embodiments of the present application can be applied to scenarios where resource mapping operations of reference objects and access resources are performed. The terminal includes, but is not limited to, the types of the above-listed terminal 11, and the network-side device includes, but is not limited to, the types of the above-listed network-side device 12. The embodiments of the present application are not limited thereto.

[0081] In the related art, in a 5G network, the SSB configuration is configured by system messages, and the resource configuration of the SSB can only be changed through radio resource control (RRC) reconfiguration. In addition, for each SSB index, the period and power of the SSB are the same, and if an SSB index does not send in a certain period, it cannot send in other periods either, unless the system message is updated, then whether an SSB index sends can be changed.

[0082] It should be noted that for different SSB indexes or SSB index groups, the load of the system may not be the same, the corresponding RO configuration does not necessarily need to be the same, and at the same time, the ratio of the mapping from the corresponding SSB to the RO does not necessarily need to be kept consistent. From another aspect, for different RO resource groups, the corresponding SSB resource configuration does not necessarily need to be kept consistent.

[0083] In view of the above problems, the embodiments of the present application provide a resource mapping method, which focuses on how to flexibly map a reference object (such as an SSB) and an access resource (RO) to each other.

[0084] Optionally, the reference object may include at least one of the following:

[0085] <1> Synchronization signal;

[0086] <2> Broadcast channel;

[0087] <3> SSB;

[0088] <4> SSB group, including at least two SSBs;

[0089] <5>Channel State Information Reference Signal (CSI-RS);

[0090] <6>CSI-RS group, including at least two CSI-RSs;

[0091] <7>Physical Uplink Shared Channel (PUSCH);

[0092] <8>PUSCH group, including at least two PUSCHs.

[0093] Optionally, the access resources may include at least one of the following:

[0094] <1>PUSCH;

[0095] <2>PUSCH group, including at least two PUSCHs;

[0098] <5>MIB;

[0099] <6>MIB group, including at least two MIBs;

[0100] <7>RO;

[0104] <11>Paging frame (PF);

[0105] <12>PF group, including at least two PFs;

[0107] <14>Carrier group, including at least two carriers;

[0108] <15>Search space;

[0109] <16>Search space set, including at least two search spaces.

[0110] Taking the reference object as the SSB / SSB set and the access resource as the RO / RO set as an example for specific illustration, the present application is not limited thereto.

[0111] Specifically, the terminal determines the mapping between the reference object and the access resource, and the mapping is related to the resource mapping information of at least one of the reference object and the access resource, where the resource mapping information may include at least one of a mapping period, an association period, a time period, and a number of mappings. Furthermore, the terminal can perform the transmission of at least one of the reference object and the access resource based on the determined mapping.

[0112] It can be understood that the resource mapping information corresponding to different reference objects and access resources may be the same or different. Furthermore, the terminal can flexibly set the corresponding mapping according to specific circumstances.

[0113] It should be noted that the mapping period, the association period, and the time period may be the same or different. Specifically:

[0114] In one embodiment, the mapping period can be interpreted as the time or period corresponding to the mapping or required between the reference object and the access resource. The association period is the time or period corresponding to the mapping cycle of an integer number of reference objects mapped to the access resource. The association pattern period includes one or more association periods.

[0115] In the resource mapping method provided by the embodiments of the present application, the terminal determines the mapping between the reference object and the access resource, and the mapping is related to the resource mapping information of at least one of the reference object and the access resource, where the resource mapping information includes at least one of a mapping period, an association period, a time period, and a number of mappings. The terminal can perform the transmission of at least one of the reference object and the access resource based on the determined mapping; compared with the related art where the mapping configurations such as the period and power of the SSB configured through system messages are all the same and the SSB configuration can only be changed by updating the system message, in the embodiments of the present application, the mapping determined by the terminal is related to flexible resource mapping information. Therefore, based on the mapping, the transmission of at least one of the reference object and the access resource can be flexibly realized, improving the flexibility of resource mapping.

[0116] Optionally, the resource mapping information is determined based on at least one of the following:

[0117] a. Configuration information, which configures at least part of the resource mapping information;

[0118] b. First information, which indicates at least part of the resource mapping information;

[0119] Among them, at least part of the information, such as a subset of the resource mapping information.

[0120] In some embodiments, the first information may be included in the configuration information or used as indication information; for example, at least part of the resource mapping information can be configured through the configuration information, and then the first information included in the configuration information indicates to actually use a certain one or a subset thereof.

[0121] Optionally, the configuration information specifically configures at least one of the following, or the first information indicates at least one of the following:

[0122] 1) At least one first mapping information respectively corresponding to at least one reference object;

[0123] Specifically, for each / some / certain SSB / SSB group, its corresponding mapping period, association period or time period can be respectively configured or indicated as the first mapping information.

[0124] If multiple mapping periods, association periods or time periods are configured for each / some / certain SSB / SSB group, a certain one or a subset thereof can be indicated to be actually used through additional signaling.

[0125] 2) At least one second mapping information corresponding to all reference objects;

[0126] Specifically, for all SSB / SSB groups, one or more mapping periods, association periods or time periods can be configured or indicated as the second mapping information.

[0127] 3) At least one third mapping information respectively corresponding to at least one access resource;

[0128] Specifically, for each / some / certain RO / RO group, its corresponding mapping period, association period or time period can be respectively configured or indicated as the third mapping information.

[0129] If multiple mapping periods, association periods or time periods are configured for each / some / certain RO / RO group, a certain one or a subset thereof can be indicated to be actually used through additional signaling.

[0130] 4) At least one fourth mapping information corresponding to all access resources.

[0131] Specifically, for all RO / RO groups, one or more mapping periods, association periods or time periods can be respectively configured or indicated as the fourth mapping information.

[0132] Optionally, the terminal can also receive second information; among them, the second information indicates at least one of the following:

[0133] 1) At least part of at least one first mapping information;

[0134] 2) Use at least part of at least one first mapping information as resource mapping information;

[0135] 3) At least part of at least one second mapping information;

[0136] 4) Use at least part of at least one second mapping information as resource mapping information;

[0137] 5) At least part of at least one third mapping information;

[0138] 6) Use at least part of at least one third mapping information as resource mapping information;

[0139] 7) At least part of at least one fourth mapping information;

[0140] 8) Use at least part of at least one fourth mapping information as resource mapping information;

[0141] 9) Fifth mapping information;

[0142] 10) The fifth mapping information covers at least part of at least one first mapping information;

[0143] 11) The fifth mapping information covers at least part of at least one second mapping information;

[0144] 12) The fifth mapping information covers at least part of at least one third mapping information;

[0145] 13) The fifth mapping information covers at least part of at least one fourth mapping information;

[0146] 14) Ignore at least part of at least one first mapping information;

[0147] 15) Ignore at least part of at least one second mapping information;

[0148] 16) Ignore at least part of at least one third mapping information;

[0149] 17) Ignore at least part of at least one fourth mapping information.

[0150] Specifically, if the configuration information configures one or more mapping periods, association periods, or time periods, additional signaling can also be used, for example, a second information is used to indicate a mapping period, an association period, or a time period. The indicated period may or may not belong to the configured one or more periods, or the indicated period may cover the configured one or more periods, or ignore the configured one or more periods.

[0151] For example, the configuration information configures the mapping period, association period, or time period corresponding to SSB1 to be 10 ms, and the mapping period, association period, or time period corresponding to SSB2 to be 20 ms.

[0152] For another example, the configuration information configures the mapping period, association period, or time period corresponding to SSB1 to be 10 ms and 20 ms, and the base station additionally indicates (for example, by the first information or the second information) to use 20 ms.

[0153] If multiple mapping periods, association periods, or time periods are configured, a certain one or a subset thereof can be indicated for actual use through additional signaling.

[0154] If one or more mapping periods, association periods, or time periods are configured, a mapping period, association period, or time period can also be indicated through additional signaling, for example, by the second information. The indicated period may or may not belong to the configured one or more periods, or the indicated period may cover the configured one or more periods, or the configured one or more periods may be ignored.

[0155] For example, the configuration information configures the mapping period, association period, or time period corresponding to all SSBs to be 80 ms.

[0156] For another example, the configuration information configures the mapping period, association period, or time period corresponding to all SSBs to be 80 ms and 160 ms, and the base station additionally indicates (for example, by the first information or the second information) to use 160 ms.

[0157] c. Predefined first rule.

[0158] Optionally, in the resource mapping information determined based on the first rule, the mapping period, association period, or time period satisfies at least one of the following:

[0159] 1) The first time required after at least one reference object is mapped to the access resource at least N1 times;

[0160] 2) The second time required after at least one access resource is mapped to the reference object at least N2 times;

[0161] Specifically, the mapping period, association period, or time period can satisfy: the time required after mapping a certain or certain SSBs / SSB groups to RO / RO groups N or N' times or at least N or N' times, or the time required after mapping a certain or certain RO / RO groups to SSBs / SSB groups N or N' times or at least N or N' times.

[0162] 3) The third time required after all reference objects are mapped to the access resource at least N3 times;

[0163] 4) The fourth time required after all access resources are mapped to the reference object at least N4 times;

[0165] It should be noted that here N may include N1 and N3, representing the number of times of mapping the reference object to the access resource; N' may include N2 and N4, representing the number of times of mapping the access resource to the reference object, where N1, N2, N3, and N4 are integers greater than 0, and N1, N2, N3, and N4 may be set to be the same or different, and no limitation is made here.

[0166] Optionally, if N1, N2, N3, and N4 are not configured, or N and / or N' are not configured, it may be defaulted to once or at least once.

[0167] 5) The first time, second time, third time, or fourth time not less than the first value;

[0168] 6) The first time, second time, third time, or fourth time not greater than the second value;

[0169] 7) Not less than the third value;

[0170] 8) Not greater than the fourth value;

[0171] 9) An integer multiple of the fifth value;

[0172] For example, the minimum time corresponding when a certain or certain SSBs are mapped to the RO at least N times, or when a certain or certain SSB groups are mapped to the RO at least N times and is an integer multiple of the fifth value.

[0173] 10) A time greater than or equal to the first time and an integer multiple of the sixth value;

[0174] 11) A time greater than or equal to the second time and an integer multiple of the seventh value;

[0175] 12) A time greater than or equal to the third time and an integer multiple of the eighth value;

[0176] 13) A time greater than or equal to the fourth time and an integer multiple of the ninth value.

[0177] It should be noted that the first value to the ninth value may be set to be the same or different, and no limitation is made here.

[0178] Optionally, the first rule may include at least one of the following:

[0179] 1) At least one sixth mapping information corresponding to at least one reference object;

[0180] 2) At least one seventh mapping information corresponding to all reference objects;

[0181] 3) At least one eighth mapping information corresponding to at least one access resource;

[0182] 4) At least one ninth mapping information corresponding to all access resources;

[0199] 21) Ignore at least part of at least one ninth mapping information.

[0200] Specifically, the above-mentioned configuration information, at least one of the first information or the second information configuration or indication can also be implemented through a predefined first rule, which will not be elaborated here.

[0201] Optionally, the mapping period, association period or time period is determined based on at least one of the following (when based on multiple items, it is for the case where different SSB groups may have different mapping periods, association periods or time periods); or, the mapping period, association period or time period is determined based on at least two of the following:

[0202] 1) The period of the target reference object;

[0203] Specifically, for example, it is the period of a specific SSB / SSB group.

[0204] Optionally, the specific SSB / SSB group can be the SSB / SSB group corresponding to the period determined by this method.

[0205] 2) The mapping period, association period or time period corresponding to the target reference object;

[0206] For example, if the mapping period, association period or time period corresponding to SSB1 is 10ms and the mapping period, association period or time period corresponding to SSB2 is 20ms, then the mapping period, association period or time period is 10ms.

[0207] 3) The period of the target access resource;

[0208] 4) The mapping period, association period or time period corresponding to the target access resource;

[0209] 5) The smallest period among the periods of at least one reference object;

[0210] Specifically, it can be the smallest period among the periods of some or all SSB / SSB groups;

[0211] 6) The smallest mapping period, association period or time period among the mapping periods, association periods or time periods corresponding to at least one reference object;

[0212] Specifically, it can be the smallest mapping period, association period or time period among the mapping periods, association periods or time periods corresponding to some or all SSB / SSB groups.

[0213] For example, if the mapping period, association period, or time period corresponding to SSB1 is 10 ms, and the mapping period, association period, or time period corresponding to SSB2 is 20 ms, then the mapping period, association period, or time period is 10 ms.

[0214] 7) The largest period among the periods of at least one reference object;

[0215] Specifically, it can be the largest period among the periods of some or all of the SSB / SSB groups.

[0216] 8) The largest mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to at least one reference object;

[0217] Specifically, it can be the largest mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to some or all of the SSB / SSB groups.

[0218] For example, if the mapping period, association period, or time period corresponding to SSB1 is 10 ms, and the mapping period, association period, or time period corresponding to SSB2 is 20 ms, then the mapping period, association period, or time period is 20 ms.

[0219] 9) The smallest period among the periods of at least one access resource;

[0220] Specifically, it can be the smallest period among the periods of some or all of the RO / RO groups.

[0221] 10) The smallest mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to at least one access resource;

[0222] Specifically, it can be the smallest mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to some or all of the RO / RO groups.

[0223] For example, if RO1 corresponds to SSB1 and the mapping period, association period, or time period corresponding to RO1 is 10 ms, and RO2 corresponds to SSB2 and the mapping period, association period, or time period corresponding to RO2 is 20 ms, then the mapping period, association period, or time period is 10 ms.

[0224] 11) The largest period among the periods of at least one access resource;

[0225] Specifically, it can be the largest period among the periods of some or all of the RO / RO groups.

[0226] 12) The largest mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to at least one access resource;

[0227] Specifically, it can be the maximum mapping period, association period, or time period among the mapping periods, association periods, or time periods corresponding to some or all of the RO / RO groups.

[0228] For example, RO1 corresponds to SSB1, and the mapping period, association period, or time period corresponding to RO1 is 10 ms. RO2 corresponds to SSB2, and the mapping period, association period, or time period corresponding to RO2 is 20 ms. Then the mapping period, association period, or time period is 20 ms.

[0229] 13) The tenth value;

[0230] Specifically, it can be a specific value, such as 160 ms.

[0231] 14) The period of the PRACH;

[0232] 15) The PRACH window;

[0233] 16) The period of the PRACH window.

[0234] Specifically, the PRACH window is used to send or detect the PRACH.

[0235] For example, in the case of non-terrestrial networks (NTN), the PRACH resources need to be configured more sparsely to match the TA ambiguity (inaccuracy or error in TA), so there may be a PRACH time window for the PRACH resources, which is one type of the PRACH windows.

[0236] Optionally, the implementation method for determining the mapping period, association period, or time period based on at least two of the following may include at least one of the following:

[0237] 1> The minimum value of at least two items;

[0238] 2> Determined based on the minimum value of at least two items and a first coefficient;

[0239] For example, the minimum value of at least two items and the first coefficient are determined by at least one of the operations of addition, subtraction, multiplication, and division.

[0240] 3> The maximum value of at least two items;

[0241] 4> Determined based on the maximum value of at least two items and a second coefficient;

[0242] 5> The greatest common divisor of at least two items;

[0243] 6>Determined based on the greatest common divisor of at least two terms and a third coefficient;

[0244] 7>The least common multiple of at least two terms;

[0245] 8>Determined based on the least common multiple of at least two terms and a fourth coefficient;

[0246] 9>Sum at least two terms;

[0247] 10>Determined based on the result of summing at least two terms and a fifth coefficient;

[0248] 11>Sum at least two terms with weights;

[0249] 12>Determined based on the result of summing at least two terms with weights and a sixth coefficient;

[0250] 13>Find the difference between at least two terms;

[0251] 14>Determined based on the result of finding the difference between at least two terms and a seventh coefficient;

[0252] 15>Find the weighted difference between at least two terms;

[0253] 16>Determined based on the result of finding the weighted difference between at least two terms and an eighth coefficient;

[0254] 17>Multiply at least two terms;

[0255] 18>Determined based on the result of multiplying at least two terms and a ninth coefficient;

[0256] 19>Multiply at least two terms with weights;

[0257] 20>Determined based on the result of multiplying at least two terms with weights and a tenth coefficient;

[0258] 21>Divide at least two terms;

[0259] 22>Determined based on the result of dividing at least two terms and an eleventh coefficient;

[0260] 23>Divide at least two terms with weights;

[0261] 24>Determined based on the result of dividing at least two terms with weights and a twelfth coefficient.

[0262] It should be noted that the above first coefficient to twelfth coefficient may be the same or different coefficients, and there is no restriction here.

[0263] For example, the mapping period, association period or time period can be determined based on at least two terms:

[0264] The mapping period, association period, or time period is the minimum / maximum / greatest common divisor / least common multiple / sum / difference / product / quotient of at least two terms. Optionally, the sum / difference / product / quotient can also be the weighted sum / difference / product / quotient of at least two terms.

[0265] The mapping period, association period, or time period is the calculation result of the minimum / maximum / greatest common divisor / least common multiple and coefficients (such as the first coefficient to the twelfth coefficient) of at least two terms. For example, the product of the sum coefficients, and the calculation method can include operations such as addition, subtraction, multiplication, and division.

[0266] Next, taking the reference object as the SSB / SSB group and the access resource as the RO / RO group as an example, the specific process of determining the mapping will be described.

[0267] Optionally, the mapping times include at least one of the following:

[0268] 1) The mapping times or the minimum mapping times N for mapping the access resource to the reference object;

[0269] 2) The mapping times or the minimum mapping times N' for mapping the reference object to the access resource.

[0270] Specifically, the determination of the mapping times N and N' of the SSB / SSB group can be based on at least one of the following:

[0271] a. Directly configured and / or indicated by the base station;

[0272] b. Derived according to specific rules. Specifically:

[0273] Determine the mapping times N and N' according to the corresponding mapping period P and the period R of the corresponding RO / RO group. Specifically:

[0274] 1> N' is related to the result of P / R, or, N is related to the result of P / R;

[0275] For example, it is the smallest integer not less than P / R;

[0276] 2> N is related to the Repetition times M, or, N' is related to the Repetition times M;

[0277] For example, it is P / (R * M).

[0278] In some embodiments, the mapping times in the embodiments of the present application can also be replaced or interpreted as the Repetition times.

[0279] Optionally, the implementation manner for the terminal to determine the mapping between the reference object and the access resource can include:

[0280] The terminal determines the mapping between the reference object and the access resource based on the resource mapping information.

[0281] Taking the reference object as the SSB / SSB group and the access object as the RO / RO group as an example, the following describes the specific implementation method for the terminal to map the access resource for the reference object based on the number of mappings in the resource mapping information.

[0282] Optionally, the implementation method for the terminal to determine the mapping between the reference object and the access resource based on the resource mapping information may include any of the following:

[0283] Method 1: The terminal maps the corresponding access resource once for each reference object in the reference object based on the number of mappings.

[0284] Specifically, the corresponding RO / RO group can be mapped once for the SSB / SSB group respectively in a certain order.

[0285] Optionally, the implementation method for mapping the corresponding access resource once for each reference object in the reference object may further include any of the following:

[0286] i. When the number of times of mapping the access resource for the first reference object in the reference object is less than or equal to the X1 value, the terminal maps the corresponding access resource for the first reference object.

[0287] Specifically, the terminal can first map the corresponding access resource once for each reference object in the reference object based on the number of mappings. If the number of times of mapping the access resource for the first reference object is less than or equal to the X1 value, it is considered that the corresponding access resource needs to be mapped for the first reference object continuously.

[0288] In some embodiments, the corresponding access resource needs to be mapped for the first reference object until the number of mappings is greater than or equal to the X1 value.

[0289] ii. When the number of times of mapping the access resource for the first reference object in the reference object is greater than or equal to the X1 value, the terminal does not map the corresponding access resource for the first reference object.

[0290] iii. When the number of times of mapping the access resource for the first reference object in the reference object is greater than or equal to the X1 value, the terminal maps the corresponding access resource for the second reference object; where the second reference object is other reference objects other than the first reference object.

[0291] Wherein, the X1 value is related to the number of mappings.

[0292] Specifically, if the number of times the first reference object maps to the access resource is greater than or equal to the X1 value, the terminal does not map the access resource corresponding to the first reference object, or maps for other reference objects other than the first reference object.

[0293] Optionally, the X1 value may satisfy at least one of the following:

[0294] 1) The number of mapping times;

[0295] 2) The number of mapping times corresponding to each reference object in the reference objects;

[0296] 3) The maximum or minimum value of the number of mapping times corresponding to at least two reference objects in the reference objects.

[0297] For example, the corresponding RO / RO group can be mapped to the SSB / SSB group once in a certain order, and then mapping starts again, and the cycle continues until all SSB / SSB groups have mapped their corresponding number of mapping times or the minimum number of mapping times.

[0298] For example, if it is necessary to map the corresponding RO / RO group to different SSB / SSB groups in a certain order (assuming the SSB / SSB group mapped first is i, and the SSB / SSB group mapped later is j), the mapping rule can be:

[0299] First, map the SSB / SSB group i and the SSB / SSB group j once respectively, and then continue to cycle and map the SSB / SSB group i and the SSB / SSB group. If after a certain traversal, the SSB / SSB group j reaches the corresponding number of mapping times, but the SSB / SSB group i has not, then in the next mapping, only the SSB / SSB group i is mapped until the SSB / SSB group i reaches the corresponding number of mapping times.

[0300] Optionally, the implementation method of mapping the corresponding access resource to each reference object in the reference objects may further include:

[0301] The terminal determines the first cumulative mapping times corresponding to the third reference object in the reference objects;

[0302] i. When the first cumulative mapping times is less than or equal to the eleventh value, the terminal continues to map the corresponding access resource to the third reference object, and / or updates the first cumulative mapping times;

[0303] Or,

[0304] ii. When the first cumulative mapping times is greater than or equal to the eleventh value, the terminal does not continue to map the corresponding access resource to the third reference object, and / or does not update the first cumulative mapping times.

[0305] Specifically, the first cumulative mapping count can be utilized to map corresponding access resources for the reference object.

[0306] Optionally, the mapping count for continuing to map corresponding access resources for the third reference object can be set to 1 time.

[0307] In some embodiments, when the first cumulative mapping count is less than or equal to the eleventh value, the terminal can continue to map corresponding access resources for the third reference object and update the first cumulative mapping count. For example, it can be incremented by 1 or A2 each time a mapping is performed until the first cumulative mapping count is greater than or equal to the eleventh value, at which point it stops mapping corresponding access resources for the third reference object and can also stop updating the first cumulative mapping count.

[0308] Optionally, a counter can be maintained for one or at least part or all of the SSB / SSB groups:

[0309] Corresponding cumulative mapping count: The counter is initially set to 0. After one or at least part or all of the SSB / SSB groups complete A1 mappings, the counter is incremented by A2; in some embodiments, A1 = A2 = 1.

[0310] In some embodiments, if the value of the counter is equal to or less than the mapping count or the minimum mapping count corresponding to one or at least part or all of the SSB / SSB groups, continue to map RO / RO groups for one or at least part or all of the SSB / SSB groups; if the value of the counter is equal to or greater than the mapping count or the minimum mapping count corresponding to one or at least part or all of the SSB / SSB groups, stop mapping RO / RO groups for one or at least part or all of the SSB / SSB groups, or do not consider one or at least part or all of the SSB / SSB groups during the next mapping.

[0311] Optionally, the eleventh value is set to at least one of the following:

[0312] 1) The mapping count corresponding to each reference object in the reference object;

[0313] 2) The maximum or minimum value among the mapping counts corresponding to at least two reference objects in the reference object.

[0314] Optionally, the first cumulative mapping count can be initially set to 0, i.e., starting from 0 for cumulative update, or it can be set to other values, which is not limited herein.

[0315] Optionally, if the mapping times of a certain / certain / all SSBs / SSB groups reach their corresponding mapping times or minimum mapping times, then the certain / certain / all SSBs / SSB groups will not be mapped during the next mapping; for all SSBs / SSB groups, the mapping times or minimum mapping times are the maximum or minimum values among multiple mapping times or minimum mapping times.

[0316] Optionally, the implementation manner of mapping the corresponding access resources once for each reference object in the reference object may further include:

[0317] The terminal determines the first remaining mapping times corresponding to the fourth reference object in the reference object;

[0318] i. When the first remaining mapping times are greater than or equal to the twelfth value, the terminal continues to map the corresponding access resources for the fourth reference object, and / or updates the first remaining mapping times;

[0319] Or,

[0320] ii. When the first remaining mapping times are less than or equal to the twelfth value, the terminal does not continue to map the corresponding access resources for the fourth reference object, and / or does not update the first remaining mapping times.

[0321] Specifically, the first remaining mapping times can be used to map the corresponding access resources for the reference object.

[0322] Optionally, the mapping times of continuing to map the corresponding access resources for the fourth reference object can be set to 1 time.

[0323] In some embodiments, when the first remaining mapping times are greater than or equal to the twelfth value, the terminal can continue to map the corresponding access resources for the fourth reference object and update the first remaining mapping times. For example, after each mapping, it is cumulatively decreased by 1 or B2 until the first remaining mapping times are less than or equal to the twelfth value, and then it does not continue to map the corresponding access resources for the fourth reference object, nor does it update the first remaining mapping times anymore.

[0324] Optionally, a counter can be maintained for one or at least part or all SSBs / SSB groups:

[0325] Corresponding to counting the remaining mapping times: The counter is first initialized to the mapping times or minimum mapping times corresponding to one or at least part or all SSBs / SSB groups, or initialized to the mapping times or minimum mapping times corresponding to one or at least part or all SSBs / SSB groups - 1. After one or at least part or all SSBs / SSB groups complete B1 times of mapping, the counter - B2; in some embodiments, B1 = B2 = 1.

[0326] In some embodiments, if the value of the counter is equal to or greater than a negative number, 0, or the minimum mapping times, continue to map RO / RO groups for one or at least part or all of the SSBs / SSB groups; if the value of the counter is equal to or less than a negative number, 0, or the minimum mapping times or a preset value, stop mapping RO / RO groups for one or at least part or all of the SSBs / SSB groups, or do not consider this one or at least part or all of the SSBs / SSB groups during the next mapping.

[0327] Optionally, the first remaining mapping times is set to at least one of the following:

[0328] 1) The mapping times corresponding to each reference object in the reference objects;

[0329] 2) The maximum or minimum value among the mapping times corresponding to at least two reference objects in the reference objects.

[0330] Optionally, the twelfth value can be set to 0, or can be set to other values, which is not limited herein.

[0331] Optionally, if the mapping times of a certain / some / all of the SSBs / SSB groups reach 0 or are less than 0, then do not map this certain / some / all of the SSBs / SSB groups during the next mapping.

[0332] Method 2: The terminal maps the corresponding access resources M1 times for each reference object in the reference objects based on the mapping times;

[0333] Wherein, M1 is an integer greater than 0.

[0334] Specifically, the corresponding mapping times or the minimum mapping times of the SSBs / SSB groups can be continuously mapped in a certain order.

[0335] Optionally, M1 satisfies at least one of the following:

[0336] 1) The mapping times corresponding to each reference object in the reference objects;

[0337] 2) The maximum or minimum value among the mapping times corresponding to at least two reference objects in the reference objects.

[0338] Optionally, the implementation manner for the terminal to map the corresponding access resources M1 times for each reference object in the reference objects based on the mapping times can include:

[0339] The terminal determines the second cumulative mapping times corresponding to the fifth reference object in the reference objects;

[0340] i. When the second cumulative mapping times is less than or equal to the thirteenth value, the terminal continues to map the corresponding access resources for the fifth reference object, and / or updates the second cumulative mapping times;

[0341] Or,

[0342] ii. When the second cumulative mapping times is greater than or equal to the thirteenth value, the terminal does not continue to map the corresponding access resources for the fifth reference object, and / or does not update the second cumulative mapping times.

[0343] Specifically, the second cumulative mapping times can be used to map the corresponding access resources for the reference object.

[0344] Optionally, the mapping times for continuing to map the corresponding access resources for the fifth reference object can be set to 1 time.

[0345] In some embodiments, when the second cumulative mapping times is less than or equal to the thirteenth value, the terminal can continue to map the corresponding access resources for the fifth reference object and update the second cumulative mapping times. For example, after each mapping, it is cumulatively incremented by 1 or A4 until the second cumulative mapping times is greater than or equal to the thirteenth value, then it does not continue to map the corresponding access resources for the fifth reference object, and the second cumulative mapping times may no longer be updated.

[0346] Optionally, a counter can be maintained for one or at least part or all of the SSB / SSB groups:

[0347] Corresponding cumulative mapping times: The counter is initially set to 0, and then after one or at least part or all of the SSB / SSB groups complete A3 mappings, the counter + A4; in some embodiments, A3 = A4 = the mapping times or the minimum mapping times corresponding to one or at least part or all of the SSB / SSB groups, or A3 = A4 = 1.

[0348] In some embodiments, if the value of the counter is equal to or less than the mapping times or the minimum mapping times corresponding to one or at least part or all of the SSB / SSB groups, continue to map the RO / RO group for one or at least part or all of the SSB / SSB groups; if the value of the counter is equal to or greater than the mapping times or the minimum mapping times corresponding to one or at least part or all of the SSB / SSB groups, no longer map the RO / RO group for one or at least part or all of the SSB / SSB groups, and / or start to map the RO / RO group for the next SSB / SSB group.

[0349] Optionally, the thirteenth value is set to at least one of the following:

[0350] 1) The mapping times corresponding to each reference object in the reference object;

[0351] 2) The maximum or minimum value of the mapping times corresponding to at least two reference objects in the reference object.

[0352] Optionally, the second cumulative mapping count can be initially set to 0, for example, i.e., starting from 0 for cumulative update, or can be set to other values, which is not limited herein.

[0353] Optionally, the implementation manner in which the terminal maps the access resources corresponding to each reference object in the reference object M1 times based on the mapping count can include:

[0354] The terminal determines the second remaining mapping count corresponding to the sixth reference object in the reference object;

[0355] i. When the second remaining mapping count is greater than or equal to the fourteenth value, the terminal continues to map the corresponding access resources for the sixth reference object, and / or updates the second remaining mapping count;

[0356] Or,

[0357] ii. When the second remaining mapping count is less than or equal to the fourteenth value, the terminal does not continue to map the corresponding access resources for the sixth reference object, and / or does not update the second remaining mapping count.

[0358] Specifically, the second remaining mapping count can be used to map the corresponding access resources for the reference object.

[0359] Optionally, the mapping count for continuing to map the corresponding access resources for the sixth reference object can be set to 1 time.

[0360] In some embodiments, when the second remaining mapping count is greater than or equal to the fourteenth value, the terminal can continue to map the corresponding access resources for the sixth reference object and update the second remaining mapping count. For example, after each mapping, it is cumulatively decreased by 1 or B4 until the second remaining mapping count is less than or equal to the fourteenth value, and then it does not continue to map the corresponding access resources for the sixth reference object, nor does it update the second remaining mapping count anymore.

[0361] Optionally, a counter can be maintained for one or at least part or all of the SSB / SSB groups:

[0362] Corresponding to counting the remaining mapping count: The counter is initially set to the mapping count or the minimum mapping count corresponding to one or at least part or all of the SSB / SSB groups, or is initially set to the mapping count or the minimum mapping count corresponding to one or at least part or all of the SSB / SSB groups - 1. After one or at least part or all of the SSB / SSB groups complete B3 mappings, the counter is decreased by B4; in some embodiments, B3 = B4 = the mapping count or the minimum mapping count corresponding to one or at least part or all of the SSB / SSB groups, or B3 = B4 = 1.

[0363] In some embodiments, if the value of the counter is equal to or greater than a negative number, 0, or the minimum mapping times, continue to map RO / RO groups for one or at least part or all of the SSB / SSB groups; if the value of the counter is equal to or less than a negative number, 0, or the minimum mapping times or a preset value, stop mapping RO / RO groups for one or at least part or all of the SSB / SSB groups, and / or, start mapping RO / RO groups for the next SSB / SSB group.

[0364] Optionally, the second remaining mapping times is set to at least one of the following:

[0365] 1) The mapping times corresponding to each reference object in the reference object;

[0366] 2) The maximum or minimum value among the mapping times corresponding to at least two reference objects in the reference object.

[0367] Specifically, the fourteenth value can be set to 0, or can be set to other values, which is not limited herein.

[0368] For example, if it is necessary to map the corresponding RO / RO groups for different SSB / SSB groups in a certain order (assuming the SSB / SSB group mapped first is i, and the SSB / SSB group mapped later is j), the mapping rule can be:

[0369] First map Ni or N’i times for the SSB / SSB group i, and then map Nj or N’j times for the SSB / SSB group j;

[0370] where Ni or N’i is the mapping times corresponding to the SSB / SSB group i, or the mapping times corresponding to all SSB / SSB groups; Nj or N’j is the mapping times corresponding to the SSB / SSB group j, or the mapping times corresponding to all SSB / SSB groups; Ni or N’i and Nj or N’j may be the same value or different, which is not limited herein.

[0372] Optionally, the implementation manner in which the terminal determines the mapping between the reference object and the access resource based on the resource mapping information may include any one of the following:

[0377] 1) The number of mappings corresponding to each access resource in the access resources;

[0378] 2) The maximum or minimum value among the number of mappings corresponding to at least two access resources in the access resources.

[0383] Or,

[0384] iii. When the number of times of mapping the reference object for the first access resource in the access resources is greater than or equal to the X2 value, the terminal maps the corresponding reference object for the second access resource; where the second access resource is other access resources except the first access resource;

[0385] Wherein, the X2 value is related to the number of mappings.

[0386] Specifically, if the number of times of mapping the reference object for the first access resource is greater than or equal to the X2 value, the terminal does not map the corresponding reference object for the first access resource, or maps other access resources except the first access resource.

[0404] Or,

[0405] ii. When the third remaining mapping times is less than or equal to the sixteenth value, the terminal does not continue to map the corresponding reference object for the fourth access resource, and / or does not update the third remaining mapping times.

[0406] Optionally, it can be implemented by maintaining a counter for one or at least part or all of the RO / RO groups.

[0407] Optionally, the third remaining mapping count is set to at least one of the following:

[0408] 1) The mapping count corresponding to each access resource in the access resources;

[0562] Figure 8It is a signaling interaction diagram of the resource mapping method provided by an embodiment of the present application. As Figure 8 shown, the method includes steps 801 to 803; where:

[0563] Step 801, the network side device sends resource mapping information to the terminal;

[0564] Specifically, the resource mapping information is used to assist in determining the mapping between the reference object and the access resource. The resource mapping information includes at least one of a mapping period, an association period, a time period, and a mapping number.

[0567] In an embodiment of the present application, the network side device sends the resource mapping information of at least one of the reference object and the access resource, which can assist the terminal in determining the mapping between the reference object and the access resource. The mapping is related to the resource mapping information, where the resource mapping information includes at least one of a mapping period, an association period, a time period, and a mapping number. The terminal can perform the transmission of at least one of the reference object and the access resource based on the determined mapping. Compared with the related art, the mapping configurations such as the period and power of the SSB configured through the system message are the same, and only by updating the system message can the configuration of the SSB be changed. In the embodiment of the present application, the network side device sends flexible resource mapping information, which can assist the terminal in flexibly determining the mapping between the reference object and the access resource, and then can flexibly implement the transmission of at least one of the reference object and the access resource based on the mapping, improving the flexibility of resource mapping.

[0568] The following is an example to illustrate the resource mapping method provided by an embodiment of the present application. Specifically, in the following example, the access resource is taken as an RO for example, and it can also be replaced with an RO group or other access resources or access resource groups, or multiple ROs are regarded as an RO group. The present application does not limit this.

[0569] Embodiment 1: The number of RO opportunities corresponding to each SSB is the same (same as legacy, even SSB-RO mapping);

[0570] Figure 9 It is one of the schematic diagrams of resource mapping in the resource mapping method provided by an embodiment of the present application. As Figure 9 shown:

[0571] Both SSB1 and SSB2 correspond to two ROs. The period of SSB1 is 20 ms, the period of SSB2 is 10 ms, and the RO resource period is 10 ms.

[0572] Assume that there are 4 ROs in each period. Then, the ROs in each period are respectively mapped to SSB1 / SSB2, and can be mapped once. The mapping period for SSB1 / SSB2 is 10 ms.

[0573] Embodiment 2: The RO opportunities and the number of mappings corresponding to each SSB may be different (uneven SSB-RO mapping);

[0574] Both SSB1 and SSB2 correspond to two ROs. The period of SSB1 is 20 ms, the period of SSB2 is 10 ms, and the RO resource period is 10 ms. Assume that there are 4 ROs in each period:

[0575] Case 1: Figure 10 It is the second schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 10 shown:

[0576] The ROs in each RO resource period are respectively mapped to the SSBs in the SSB period corresponding to this RO resource period, and are mapped once. The slant-shaded part is the RO that is not mapped to the SSB.

[0577] Then, the mapping period for SSB1 is 20 ms, and the mapping period for SSB2 is 10 ms.

[0578] Or, the mapping period for SSB1 / SSB2 is max(10 ms, 20 ms) = 20 ms;

[0579] In another implementation, the base station directly configures or indicates that the mapping period for SSB1 is 20 ms, and the mapping period for SSB2 is 10 ms.

[0580] In another implementation, the base station directly configures or indicates that the mapping period is 20 ms.

[0581] Case 2: Figure 11 It is the third schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 11 shown:

[0582] The ROs in each RO resource period are respectively mapped to the SSBs in the SSB period corresponding to this RO resource period, and are mapped at least once. Then, in the first and third RO resource periods, SSB1 / SSB2 and the RO can be respectively mapped once. In the second and fourth RO resource periods, SSB2 and the RO can be mapped twice.

[0583] Then, the mapping period for SSB1 is 20 ms, and the mapping period for SSB2 is 10 ms.

[0584] Alternatively, for the mapping period of SSB1 / SSB2, it is max(10 ms, 20 ms) = 20 ms.

[0585] In another implementation, the base station directly configures or indicates that the mapping period of SSB1 is 20 ms, and for SSB2, the mapping period is 10 ms.

[0586] In another implementation, the base station directly configures or indicates that the mapping period is 20 ms.

[0587] Case 3 Figure 12 is the fourth schematic diagram of resource mapping in the resource mapping method provided by the embodiments of the present application, as Figure 12 shown:

[0588] The mapping period of SSB1 is 10 ms, and for SSB2, the mapping period is 40 ms.

[0589] Then the mapping period of SSB1 is 40 ms, and for SSB2, the mapping period is 10 ms.

[0590] Alternatively, for the mapping period of SSB1 / SSB2, it is max(10 ms, 40 ms) = 40 ms.

[0591] In another implementation, the base station directly configures or indicates that the mapping period of SSB1 is 40 ms, and for SSB2, the mapping period is 10 ms.

[0592] In another implementation, the base station directly configures or indicates that the mapping period is 40 ms.

[0593] Embodiment 3: The base station directly configures the mapping period and / or the minimum mapping times;

[0594] Case 1 Figure 13 is the fifth schematic diagram of resource mapping in the resource mapping method provided by the embodiments of the present application, as Figure 13 shown:

[0595] Both SSB1 and SSB2 correspond to two ROs. The period of SSB1 is 20 ms, the period of SSB2 is 10 ms, and the period of RO resources is 20 ms.

[0596] Assume that there are 4 ROs in each period. The base station directly configures or indicates that the mapping period of SSB1 is 80 ms, and for SSB2, the mapping period is 20 ms.

[0597] Then in the first and fifth RO resource periods, SSB1 / SSB2 and RO can be mapped once respectively.

[0598] In the second, third, and fourth RO resource periods, SSB2 and RO can be mapped twice.

[0599] Case 2: Figure 14 It is the sixth schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 14 shown:

[0600] In another implementation, the base station directly configures or indicates that the minimum mapping times of SSB1 within the mapping period is 1, and the minimum mapping times of SSB2 within the mapping period is 6. Thus, the minimum value that meets the above requirements and is an integer multiple of the RO resource period can be determined as 80 ms, and thus the mapping period of SSB1 / SSB2 is determined as 80 ms. Or in another implementation, the base station directly configures or indicates that the mapping period of SSB1 / SSB2 is 80 ms;

[0601] Then within one mapping period, SSB1 / SSB2 and RO can be mapped once and seven times respectively.

[0602] Case 3: Figure 15 It is the seventh schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 15 shown:

[0603] In another implementation, the base station directly configures or indicates that the mapping times of SSB1 within the mapping period is 1, and the mapping times of SSB2 within the mapping period is 6.

[0604] Then within one mapping period, SSB1 / SSB2 and RO can be mapped once and six times respectively.

[0605] Thus, the minimum value that meets the above requirements and is an integer multiple of the RO resource period can be determined as 80 ms, and thus the mapping period of SSB1 / SSB2 is determined as 80 ms. Or in another implementation, the base station directly configures or indicates that the mapping period of SSB1 / SSB2 is 80 ms.

[0606] Embodiment 4: Mapping rules under uneven mapping;

[0607] Example of Method 1 Figure 16 It is the eighth schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 16 shown:

[0608] The mapping times N1 of SSB / SSB group 1 is 2, and the mapping times N2 of SSB / SSB group 2 is 6;

[0609] Then SSB / SSB group 1 and SSB / SSB group 2 are mapped once respectively first, and then SSB / SSB group 2 is mapped 5 times;

[0610] One implementation is to maintain a counter X and a counter Y for SSB / SSB group 1 and SSB / SSB group 2 respectively, and initialize X and Y to 0;

[0611] For SSB / SSB group 1:

[0612] 1) If X < N1, map SSB / SSB group 1. After one mapping, X = X + 1; and determine whether there are other SSB / SSB groups that need to be mapped. In the embodiment of the present application, there is still SSB / SSB group 2 that needs to be mapped.

[0613] For SSB / SSB group 2:

[0614] 2) If Y < N2, map SSB / SSB group 2. After one mapping, Y = Y + 1; and determine whether there are other SSB / SSB groups that need to be mapped.

[0615] If not, go back to 1) and determine whether to continue mapping; if X >= N1 and Y < N2, continue to perform the mapping of SSB / SSB group 2 until Y < N2 is no longer satisfied.

[0616] Example of Method 2 Figure 17 is the ninth schematic diagram of resource mapping in the resource mapping method provided by the embodiment of the present application, as Figure 17 shown:

[0617] The mapping times N1 of SSB / SSB group 1 is 2, and the mapping times N2 of SSB / SSB group 2 is 6;

[0618] Then SSB / SSB group 1 is mapped once first, and then SSB / SSB group 2 is mapped 6 times;

[0619] One implementation is to maintain a counter X and a counter Y for SSB / SSB group 1 and SSB / SSB group 2 respectively, and initialize X and Y to 0;

[0620] For SSB / SSB group 1:

[0621] 1) If X < N1, map SSB / SSB group 1. After one mapping, X = X + 1; if X is still < N1, continue mapping until X < N1 is no longer satisfied. Then check whether there are other SSB / SSB groups that need to be mapped. In the embodiment of the present application, there is still the SSB / SSB group for which SSB / SSB group 2 is mapped.

[0622] For SSB / SSB group 2:

[0623] 2) If Y < N2, map SSB / SSB group 2. After one mapping, Y = Y + 1; and determine whether to continue mapping. If Y < N2, continue to perform the mapping of SSB / SSB group 2 until Y < N2 is no longer satisfied.

[0624] Further, in the above embodiment, a gap between two mappings corresponding to an SSB / SSB group can also be obtained. The gap can be the number of RO / RO groups, duration, or frequency domain interval, so that the gap between two mappings can be controlled.
