Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person skilled in the art without creative work fall within the protection scope of the present disclosure.

[0040] Unless otherwise required by context, the term “comprise” and other forms such as “comprises”, “comprises”, and “comprising” are to be construed as open, inclusive, meaning that “comprising” means “including, but not limited to”. In the description of the specification, the terms “one embodiment”, “some embodiments”, “exemplary embodiments”, “example”, “specific example” or “some examples” and the like are intended to mean that the specific features, structures, materials or characteristics related to that embodiment or example are included in at least one embodiment or example of the present disclosure. The illustrative representation of the above terms does not necessarily mean the same embodiment or example. In addition, the specific features, structures, materials or characteristics described can be included in any one or more embodiments or examples in any appropriate manner.

[0041] The terms “first”, “second”, and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, the meaning of “a plurality of” is two or more than two of the corresponding objects.

[0042] In the embodiments of the present disclosure, the words "exemplary" or "for example" are used to mean serving as an example or illustration. Any embodiment or design presented as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or advantageous than other embodiments or designs in the present disclosure. In fact, the use of the words "exemplary" or "for example" is intended to present concepts in a particular manner.

[0043] In the embodiments of the present disclosure, "or" means one of the corresponding objects, or a plurality of the corresponding objects.

[0044] In addition, the use of "based on" means the openness and inclusiveness of the conditions, because the process, step, calculation or other action "based on" one or more said conditions or values can be based on additional conditions or beyond the said values in practice.

[0045] Before describing the technical solutions of the present disclosure, some technical terms are first explained.

[0046] The synchronization broadcast signal block, which can also be referred to as a synchronization broadcast block, is composed of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), data of a physical broadcast channel (PBCH), and a demodulation reference signal (DMRS). The SSB is mainly used for cell search, beam measurement, beam selection, beam recovery, etc., and is one of the key signals for user equipment (UE) to access a cell. The PSS provides a preliminary synchronization result in advance, and a preliminary synchronization is completed with a small number of sequences. The SSS is later, and further synchronization is performed according to the SSS.

[0047] In the 5th generation mobile communication technology (5G) system, if a terminal accessing the network in 5M is considered, the reception of the synchronization broadcast signal block (SSB), system information block (SIB), etc. of the channel has obvious performance loss. Therefore, for 6G or future wireless systems, a unified air interface access mechanism is considered to be designed, including at least one of a synchronization signal block, a control channel, a shared channel or a data channel, to adapt to terminals accessing the network in different scenarios or capabilities.

[0048] FIG. 1 is a structural diagram of an SSB according to an embodiment of the present disclosure. Referring to FIG. 1, the SSB includes an SSS, a PSS, and a PBCH.

[0049] In a long term evolution (LTE) system, the time-frequency domain resource of the SSS is fixed. For example, the time-frequency domain resource of the SSS can refer to the following content.

[0050] For the frequency domain resource, the SSS occupies a frequency domain resource of 62 subcarriers. The subcarrier spacing of the LTE system is 15 kHz, so in the frequency domain, the bandwidth occupied by the SSS is 62*15 kHz = 930 kHz.

[0051] For the time domain resource, the SSS is located in the last orthogonal frequency division multiplexing (OFDM) symbol of the 0th and 10th slots of a subframe. In some embodiments, the SSS occupies one OFDM symbol in each of two subframes (subframe 0 and subframe 5) in a 10 ms radio frame. Therefore, the SSS occupies 1 OFDM symbol and is repeated in the radio frame.

[0052] In summary, for the PSS and SSS design of the LTE: in the time domain, the SSS occupies a total of 1 OFDM symbol; in the frequency domain, the SSS occupies a total of 62 subcarriers (a bandwidth of 930 kHz).

[0053] For a control resource set (CORESET), it is defined as follows: a control resource set consists of resource blocks in the frequency domain and symbols in the time domain.

Compared with the original SSB, its structure is simplified, or optimized according to the super cell of 6G or the cell-free scenario, to adapt to terminals with different bandwidth capabilities to access the network.

[0093] The synchronization signal block provided by the embodiments of the present disclosure can have other names, such as a virtual cell information block or a sub-cell synchronization information block, and the embodiments of the present disclosure do not limit this.

[0094] Taking the synchronization signal block provided by the embodiments of the present disclosure including SSS and PBCH and the control channel being PDCCH as an example, the synchronization signal block and the PDCCH satisfy the following relationship in the time domain and the frequency domain. Time domain:

[0095] FIG. 4 shows a position relationship diagram of a synchronization signal block and a PDCCH provided by an embodiment of the present disclosure. Referring to FIG. 4, there is a certain offset between the synchronization signal block and the PDCCH in the time domain.

[0096] In some embodiments, the center frequency point or the specific subcarrier of the CORESET of the PDCCH has a certain offset with the center frequency point or the specific subcarrier of the PBCH or the synchronization signal block. The offset has a positive or negative value, for example, the offset value includes at least one of the offset values shown in Table 1 below.

[0097] Table 1

[0098] In some embodiments, the boundary subcarrier or the boundary RB of the CORESET of the PDCCH has a certain offset with the boundary subcarrier or the boundary RB of the PBCH or the synchronization signal block. The offset has a positive or negative value.

[0099] FIG. 5 shows another position relationship diagram of a synchronization signal block and a PDCCH provided by an embodiment of the present disclosure. Referring to FIG. 5, there is a certain interval between the synchronization signal block and the PDCCH in the frequency domain.

[0100] In some embodiments, the center frequency point / specific subcarrier / specific RB of the CORESET of the PDCCH is different from the center frequency point / specific subcarrier / specific RB of the PBCH or the synchronization signal block in terms of band, frequency band or frequency point. The specific subcarrier includes the subcarrier of the center frequency point, the subcarrier adjacent to the center frequency point, the subcarrier of the upper boundary or the lower boundary, etc. The specific RB includes the RB of the center frequency point, the RB adjacent to the center frequency point, the RB of the upper boundary or the lower boundary, etc.

[0101] In some embodiments, the PBCH is used to indicate the band number or the band quantity of the PDCCH. The frequency location of the PDCCH monitoring is pre-configured, for example, the default monitoring location is at the center frequency point.

[0102] In some embodiments, the frequency domain location of the PDCCH is above and / or below the synchronization signal block.

[0103] For example, FIG. 6 is a schematic diagram of the location relationship between the synchronization signal block and the PDCCH according to an embodiment of the present disclosure, where the frequency domain location of the PDCCH is above the synchronization signal block.

[0104] For another example, FIG. 7 is another schematic diagram of the location relationship between the synchronization signal block and the PDCCH according to an embodiment of the present disclosure, where the frequency domain location of the PDCCH is below the synchronization signal block.

[0105] For another example, FIG. 8 is another schematic diagram of the location relationship between the synchronization signal block and the PDCCH according to an embodiment of the present disclosure, where the frequency domain location of the PDCCH is above and below the synchronization signal block.

[0106] In some embodiments, the time domain location of the PDCCH overlaps or is the same as the time domain location of the synchronization signal block. For example, the synchronization signal block occupies symbols 0, 1, 2 and 3, and the PDCCH occupies symbols 0, 1, 2 and 3.

[0107] FIG. 9 is another schematic diagram of the location relationship between the synchronization signal block and the PDCCH according to an embodiment of the present disclosure. Referring to FIG. 9, there is an overlap between the synchronization signal block and the PDCCH in the time domain and the frequency domain.

[0108] In some embodiments, the location relationship between the PBCH and the PDCCH is determined according to the PDCCH type, the bandwidth and the format.

[0109] For example, for a PDCCH with a smaller bandwidth, the PDCCH is time-divisioned with the synchronization signal or the PBCH. For a PDCCH with a larger bandwidth, the PDCCH is time-divisioned and frequency-divisioned with the synchronization signal, or frequency-divisioned, or time-divisioned.

[0110] In some embodiments, the location relationship between the PDCCH and the synchronization signal is determined in the following manner:

[0111] Way 1: Customized location relationship, i.e. the location relationship of PDCCH is not associated with PSS, SSS, PBCH. The location relationship of PDCCH is defined based on system frame number (SFN), symbol, slot, period, offset.

[0112] Way 2: Associated with PBCH, i.e. the location of PDCCH is indicated by PBCH, including the time domain location and frequency domain location of PDCCH.

[0113] Way 3: Associated with PSS / SSS, when PDCCH and PSS / SSS are in the same radio frame, PDCCH and PSS / SSS are both in a specific time domain location. Alternatively, PDCCH and PSS / SSS have the same center frequency point.

[0114] In some embodiments, the synchronization signal block, the synchronization signal and the monitoring occasion of PDCCH are associated.

[0115] As an example, the synchronization signal block, the synchronization signal and the monitoring occasion of PDCCH are associated in the frequency domain, and the control channel is determined according to the synchronization signal block, including that the monitoring occasion of the control channel is determined according to the index of the synchronization signal block.

[0116] FIG. 10 is a schematic diagram of the association of the synchronization signal block, the synchronization signal and the monitoring occasion of PDCCH in the frequency domain according to an embodiment of the present disclosure.

[0117] Taking PDCCH as an example, the location of PDCCH occasion is determined according to the index of the synchronization signal block, the index of the frequency domain location, the index of the time domain location, the index of the beam, and the category of the synchronization signal block.

[0118] The category of the synchronization signal block includes: a single-beam synchronization signal block, a cluster-beam synchronization signal block, a wide-beam synchronization signal block, a narrow-beam synchronization signal block, and a synchronization signal block with different numbers of beams.

[0119] In some embodiments, the index of the synchronization signal block corresponds to the PDCCH occasion, and the location of the PDCCH occasion can be determined according to the index value, or the bandwidth or the number of time domain symbols of the PDCCH is determined according to the index value.

[0120] In some embodiments, the frequency domain location index of the synchronization signal block corresponds to the PDCCH occasion, for example, the synchronization signal block with index = 0 in the frequency domain location corresponds to the PDCCH occasion in the same frequency band location. Alternatively, the bandwidth or the number of time domain symbols of the PDCCH is determined according to the frequency domain location index of the synchronization signal block.

[0121] In some embodiments, the time domain location index of the synchronization signal block, such as slot number, is used to determine the location of the starting PDCCH occasion, and the PDCCH occasion can also be time-division, i.e., in different time domain locations. Alternatively, the bandwidth or the number of time domain symbols of the PDCCH is determined according to the time domain location index of the synchronization signal block, and in different time domain locations, there are different PDCCH bandwidths or different numbers of time domain resources.

[0122] In some embodiments, the beam index of the synchronization signal block implicitly corresponds to the time-frequency domain location of the synchronization signal block, and each beam index corresponds to a PDCCH occasion. Alternatively, the number of frequency domain resources or the number of time domain resources of the PDCCH is determined according to the beam index of the synchronization signal block.

[0123] It should be noted that when the categories of the synchronization signal blocks are different, the locations of the corresponding PDCCH occasions are different, the number of frequency domain resources of the PDCCH is different, or the number of time domain resources of the PDCCH is different.

[0124] FIG. 11 shows a beam type diagram provided by an embodiment of the present disclosure. In some embodiments, one beam of the PBCH can correspond to at least one beam of the PDCCH. Alternatively, at least one beam of the PBCH can correspond to one beam of the PDCCH.

[0125] In some embodiments, the time-frequency domain resources of the PDCCH or the PDCCH monitoring occasion location is determined according to the time domain interval or the frequency domain interval between the synchronization signal blocks.

[0126] For example, when the frequency domain interval between the synchronization signal blocks is large, the PDCCH has more frequency domain resources or more time domain resources. When the frequency domain interval between the synchronization signal blocks is small, the PDCCH has fewer frequency domain resources or fewer time domain resources.

[0127] For another example, when the time domain interval between the synchronization signal blocks is large, the PDCCH has more time domain resources and fewer frequency domain resources. When the time domain interval between the synchronization signal blocks is small, the PDCCH has fewer time domain resources and more frequency domain resources. The time domain interval is embodied as a period or a time interval between two synchronization signal blocks.

[0128] FIG. 12 is a schematic diagram illustrating a method of determining the location of PDCCH time-frequency domain resources or monitoring occasions according to time domain intervals, according to an embodiment of the present disclosure.

[0129] In some embodiments, the location of PDCCH occasions can be determined according to time domain intervals or frequency domain intervals between synchronization signal blocks, for example, the location of half of a period is the location of PDCCH occasions, in which case the location of PDCCH occasions varies according to the size of the period.

[0130] In some embodiments, multiple sets of PDCCH / SIBs can be transmitted within a super cell, for example, one set of PDCCH / SIBs is transmitted under each sub cell (cell) in the super cell. This means that the scrambling of PDCCH, radio network temporary identifier (RNTI) is based on the ID or index of the super cell. When each sub cell transmits PDCCH or SIB1, it can be considered whether the scrambling of PDCCH is based on the super cell ID or the cell ID of the sub cell, or both. For example, it can be determined by PBCH indication.

[0131] According to the indication or payload of the synchronization signal block, the time-frequency domain resources of the control channel are determined, including determining the time-frequency domain resources of the control channel according to the indication or payload of the PBCH in the synchronization signal block.

[0132] For example, the PBCH indicates at least one of the starting position of the PDCCH frequency domain resources, the number of frequency domain resources (such as the number of RBs, the number of CCEs), etc.

[0133] For another example, the PBCH indicates the starting position of the PDCCH time domain resources, the number of time domain resources (such as the number of symbols 2, 3, 4), etc.

[0134] For another example, the PBCH indicates the coefficient of the PDCCH time domain or frequency domain resources, 1 / 2, 1 / 4, 1, 2, 4, etc., different coefficients will scale the default PDCCH time-frequency domain resources. For example, when the coefficient is 2, the time domain or frequency domain resources will be doubled.

[0135] For example, the PBCH indicates the PDCCH time-frequency domain resource candidate according to the location in the frequency domain. For example, at frequency point 1, the PDCCH time domain resource is 1, 2, 3, 4 symbols, and the PBCH indicates one of 1, 2, 3, 4 symbols. At frequency point 2, the PDCCH time domain resource is 1, 2, 3, 4 slots, and the PBCH indicates one of 1, 2, 3, 4 slots. At frequency point 3, the PDCCH time domain resource is 2, 4 symbols, 1, 2 slots; the PBCH indicates one of these information.

[0136] In some embodiments, the synchronization signal block or the PBCH in the synchronization signal block is used to indicate whether the control channel has an associated control channel or search space, for example, the synchronization signal block or the PBCH in the synchronization signal block is used to indicate whether the first control channel has the second control channel or the search space, and the first control channel or the search space is a default configuration. For example, the following indication mode can exist.

[0137] Mode 1, the synchronization signal block is used to indicate the first time-frequency domain resource or the second time-frequency domain resource of the control channel.

[0138] The first time-frequency domain resource and the second time-frequency domain resource satisfy at least one of the following: the first time-frequency domain resource and the second time-frequency domain resource have the same reference location; the resource elements of the first time-frequency domain resource are a subset of the resource elements of the second time-frequency domain resource; the bandwidth of the first time-frequency domain resource and the bandwidth of the second time-frequency domain resource satisfy a certain proportion; the number of symbols of the first time-frequency domain resource and the number of symbols of the second time-frequency domain resource satisfy a certain proportion; the first time-frequency domain resource and the second time-frequency domain resource are continuous in the time domain; the first time-frequency domain resource and the second time-frequency domain resource have a certain offset in the time domain; the first time-frequency domain resource and the second time-frequency domain resource are located in the same time slot, subframe, radio frame or time unit in the time domain; the first time-frequency domain resource and the second time-frequency domain resource are in different frequency ranges, frequency band numbers, carriers or cells; the first time-frequency domain resource and the second time-frequency domain resource have the same starting time domain location; the first time-frequency domain resource and the second time-frequency domain resource determine the corresponding time-frequency domain resource according to the frequency range, frequency band number, carrier or cell where they are located.

[0139] The above bandwidth can be embodied as a certain number of frequency domain resources, such as the number of RBs, the number of subcarriers, the number of REs, etc. The time unit includes time units such as time slot, subframe, radio frame, ms (millisecond), us (microsecond), symbol, etc., but is not limited thereto, for example, the time unit can also be a time unit defined based on a certain frequency, sampling rate. In short, the time unit is a time length defined based on a certain rule, for example, a plurality of symbols, the symbol is an OFDM symbol, which is defined based on the subcarrier spacing of the OFDM system.

[0140] The first time-frequency domain resource and the second time-frequency domain resource have the same reference position, which can be that the first time-frequency domain resource and the second time-frequency domain resource have the same center frequency, the same upper boundary frequency, or the same lower boundary frequency.

[0141] The bandwidth of the first time-frequency domain resource and the bandwidth of the second time-frequency domain resource satisfy a certain proportion, which can be that the bandwidth of the first time-frequency domain resource is half of the bandwidth of the second time-frequency domain resource, that is, the certain proportion is fifty percent. The number of symbols of the first time-frequency domain resource and the number of symbols of the second time-frequency domain resource satisfy a certain proportion, which can be that the number of symbols of the first time-frequency domain resource is half of the number of symbols of the second time-frequency domain resource.

[0142] In some embodiments, the synchronization signal block is used to indicate the first time-frequency domain resource or the second time-frequency domain resource of the control channel, including that the PBCH in the synchronization signal block is used to indicate the first time-frequency domain resource or the second time-frequency domain resource of the control channel.

[0143] FIG. 13 is a schematic diagram of the PBCH indicating the first time-frequency domain resource or the second time-frequency domain resource of the control channel according to an embodiment of the present disclosure.

[0144] In mode 2, the synchronization signal block is used to indicate the first time-frequency domain resource and the second time-frequency domain resource of the control channel.

[0145] For the description of the relationship between the first time-frequency domain resource and the second time-frequency domain resource, reference can be made to the corresponding description in mode 1, which is not repeated here.

[0146] As an example, the PBCH in the synchronization signal block is used to indicate the first time-frequency domain resource and the second time-frequency domain resource of the control channel. FIG. 14 is a schematic diagram of the PBCH indicating the first time-frequency domain resource and the second time-frequency domain resource of the control channel according to an embodiment of the present disclosure.

[0147] In some embodiments, 1 bit in the PBCH, 0 / 1 indicates the first time-frequency domain resource of the control channel, and 1 / 0 indicates the second time-frequency domain resource of the control channel. 2 bits in the PBCH, 00 indicates the first time-frequency domain resource of the control channel, 11 indicates the second time-frequency domain resource of the control channel, 01 indicates no SIB1, and 10 indicates the first time-frequency domain resource and the second time-frequency domain resource respectively. When the PBCH is used to indicate the first time-frequency domain resource or the second time-frequency domain resource of the control channel, the indication state is as 2 bits, or can be other, such as 10, 11, 00, and 01. The first time-frequency domain resource and the second time-frequency domain resource are continuous in the time domain; or differ by a certain offset; or are in the same slot, subframe, or radio frame.

[0148] Based on the above embodiments, the terminal of the first scenario or the first type of capability can perform cell search or access or acquire information based on the first time-frequency domain resource of the control channel, or the terminal of the second scenario or the second type of capability can perform cell search or access or acquire information based on the second time-frequency domain resource of the control channel, thereby realizing access of terminals of different scenarios or capabilities to the network.

[0149] In the embodiments of the present disclosure, the structure of the synchronization signal block is improved, and the time-frequency domain resource of the control channel can be determined based on the synchronization signal block provided by the embodiments of the present disclosure, so as to adapt to the access of terminals of different scenarios or capabilities to the network.

[0150] In the above embodiments, the time-frequency domain resource of the control channel is determined based on the synchronization signal block as an example, and in some embodiments, the time-frequency domain resource of the control channel is determined according to at least one of the following: the type or format of the control channel; the demodulation reference signal of the control channel; the frequency point position, frequency range, frequency band number, carrier or cell of the control channel; the subcarrier spacing of the control channel.

[0151] As can be seen from the above, the time-frequency domain resource of the control channel can be determined based on some parameters of the control channel.

[0152] Through the type, format, frequency point position, frequency range, frequency band number, carrier, cell or subcarrier spacing of the control channel, the number of resources of the control channel can be determined, such as bandwidth, number of time domain symbols, etc.

[0153] As an example, the time-frequency domain resource of the control channel is determined according to the demodulation reference signal of the control channel, including at least one of the following cases:

[0154] According to the demodulation reference signal, the number of symbols or time slots of the control channel is determined to be at least one of {1, 2, 3, 4, 6, 8, 12, 14};

[0155] According to the demodulation reference signal, the bandwidth of the control channel is determined to be at least one of {1, 2, 4, 8} * N, N is a frequency domain resource, for example, N is 12 RBs, 6 RBs, etc.;

[0156] According to the demodulation reference signal, the time-frequency domain resource of the control channel is at least one of a first pattern, a second pattern, a third pattern or a fourth pattern, wherein the pattern is used to describe the resource in the time domain and the frequency domain, and different patterns correspond to different time domain resources or frequency domain resources.

[0157] In some embodiments, the "or" in "different patterns correspond to different time domain resources or frequency domain resources" can be replaced by "and / or", that is, different time domain resources or frequency domain resources can refer to three cases: different time domain resources, different frequency domain resources, and different time domain resources and frequency domain resources.

[0158] Taking determining the time-frequency domain resource of the control channel according to the frequency point position of the control channel as an example, for the control channel at a high frequency point, the control channel has more symbol quantities in a certain bandwidth, such as one slot. For the control channel at a low frequency point, the symbol quantity of the control channel in a certain bandwidth is less.

[0159] Different control channel types / formats have different symbol quantities or slot quantities. For example, a first control channel type / format corresponds to a symbol-level control channel, that is, the symbol quantity occupied by the control channel corresponding to the first control channel type / format is less than or equal to X, X is less than or equal to 14 or 13. A second control channel type / format is a slot-level control channel, that is, the resource occupied by the control channel corresponding to the second control channel type / format needs at least one slot, for example, the resource occupied by the control channel is in slot n and slot n+1.

[0160] FIG. 15 is a schematic diagram of a time-frequency domain resource of a control channel provided by an embodiment of the present disclosure. Referring to FIG. 15, in a frequency range 2, the control channel occupies 2 slots; in a frequency range 1, the control channel occupies 1 slot.

[0161] The above embodiments are described by taking some parameters of the control channel to determine the time-frequency domain resource of the control channel as an example. In some embodiments, the time-frequency domain resource of the control channel can be determined according to a preset table. For example, the RB quantity can be 6, 12, 24, and the symbol quantity can be at least one of {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}. The slot quantity is at least one of {1, 2, 3, 4, 5, 6, 7, 8}. The frequency range, frequency position, frequency band number, etc. of the control channel can be determined from Table 2 based on the frequency index.

[0162] Table 2

[0163] In some embodiments, the time-frequency domain resource of the control channel is determined according to the demodulated reference signal.

[0164] The above embodiments introduce the determination of the time-frequency domain resource of the control channel. In some embodiments, the time-frequency domain resource of the control channel can be as shown in FIG. 16. Referring to FIG. 16, the time-frequency domain resource of the control channel includes a first DMRS and a second DMRS. The REs in FIG. 16 are resource elements.

[0165] As can be seen from the above description, the time-frequency domain resource of the control channel can be determined based on the demodulation reference signal of the control channel.

[0166] Exemplarily, the number of symbols of the control channel is determined by the demodulation reference signal of the control channel. For example, the number of symbols of the control channel is determined by the first DMRS of the control channel, including being indicated by a plurality of DMRS sequences. When the first DMRS of the control channel indicates a plurality of symbols, the second DMRS of the control channel is mapped.

[0167] The first DMRS and the second DMRS have a nested relationship, or the second DMRS is obtained based on the first DMRS.

[0168] In some embodiments, the first DMRS indicates 1 bit information or 2 bit information.

[0169] Exemplarily, the number of RBs of the control channel, the frequency domain bandwidth is determined by the demodulation reference signal of the control channel. For example, the frequency domain bandwidth of the control channel includes 12 RBs, 24 RBs, 48 RBs, 96 RBs, and is indicated by the first DMRS of the control channel.

[0170] In some embodiments, the first DMRS indicates one of 12 RBs or 24 RBs.

[0171] As an example, based on 3 bits in the demodulation reference signal of the control channel or the PBCH in the synchronization signal block, the time-frequency domain resource of the control channel is indicated, and the corresponding relationship can be shown in Table 3 as follows:

[0172] Table 3

[0173] For example, in combination with Table 3 described above, the DMRS carries 2 bits of information, and there are 4 states in total. Based on 12 RBs and 2 symbols, the time-frequency domain resource occupied by the control channel is indicated. When it is indicated as 00, or index = 0, the resource is not expanded, and it is still 12 RBs and 2 symbols, and the control channel is also mapped based on these resources. When it is indicated as 01 or index = 1, the time domain resource is doubled, i.e. 4 symbols, 12 RBs. When it is indicated as 10 or index = 2, the frequency domain resource range is unchanged, i.e. the frequency domain is 24 RBs, and the time domain is 2 symbols. When it is indicated as 11 or index = 3, both the frequency domain resource and the time domain resource are increased, i.e. the frequency domain resource is 24 RBs, and the time domain resource is 4 symbols.

[0174] As an example, for a demodulation reference signal for a control channel scheduling SIB1, the generation of the demodulation reference signal sequence is determined according to ID information carried by the synchronization signal. The ID information includes first ID information of the first synchronization signal, or second ID information of the second synchronization signal. Or the ID information is determined by the first ID information and the second ID information.

[0175] For example, the ID information is determined by the first ID information and the second ID information, including N ID = M * X1+ X2.

[0176] Wherein, N ID Refers to ID information, M > 3, wherein the value range of X2 is 0 ~ M-1, and the first ID information is the first ID information. The value range of X1 is 0 ~ m, and m is at least 336, and the second ID information is the second ID information. Alternatively, X1 is the first ID information, and the value range is 0 ~ m, and the second ID information is the second ID information, and the value range is 0 ~ n. The value of M is n-1 or n or n+1.

[0177] For another example, the first ID information is the ID information of a large range cell (for example, super cell), and the second ID information is the ID information of a small range cell (for example, virtual cell).

[0178] As an example, for a demodulation reference signal for a control channel scheduling SIB1, the generation of the demodulation reference signal sequence is determined according to ID information carried by the synchronization signal. The ID information includes first ID information of the first synchronization signal, or second ID information of the second synchronization signal, or third ID information of the third synchronization signal. Or the ID information is determined by at least one of the first ID information, the second ID information, and the third ID information.

[0179] For example, the first ID information is the ID information of a large range cell (for example, super cell), the second ID information is the ID information of a small range cell (for example, virtual cell), and the third ID information is the ID information of a smaller cell (for example, virtual cell) in the small range cell. The second ID information is carried by the primary synchronization signal, and the third ID information is carried by the secondary synchronization signal.

[0180] For another example, the ID information is determined by at least one of the first ID information, the second ID information, and the third ID information, including N ID = M * X1+ N * X2+ X3.

[0181] Wherein, N ID Refers to ID information, X1 is the first ID information, and the value range is 0 ~ m-1; X2 is the second ID information, and the value range is 0 ~ n-1; X3 is the third ID information, and the value range is 0 ~ p-1. The value of M is p*n, and the value of N is p.

[0182] In combination with the above examples, the demodulation reference signal of the control channel is determined based on at least one of the first synchronization signal, the second synchronization signal, or the third synchronization signal, including at least one of the following cases:

[0183] The demodulation reference signal of the control channel is determined based on the second synchronization signal and the third synchronization signal, wherein the second synchronization signal and the third synchronization signal are determined according to the first synchronization signal; or

[0184] The demodulation reference signal of the control channel is determined based on the first synchronization signal and the second synchronization signal, and the second synchronization signal is determined according to the first synchronization signal; or

[0185] The demodulation reference signal of the control channel is determined based on the third synchronization signal, and the third synchronization signal is determined according to the first synchronization signal and / or the second synchronization signal.

[0186] In some embodiments, the demodulation reference signal of the control channel is determined based on information, identification information, or index information carried by at least one of the first synchronization signal, the second synchronization signal, or the third synchronization signal.

[0187] In some embodiments, the beam of the control channel or the beam of the demodulation reference signal of the control channel is associated with the synchronization signal block, for example, associated with the first synchronization signal, the second synchronization signal, or the broadcast channel in the synchronization signal block.

[0188] Based on the first synchronization signal, the second synchronization signal, and the third synchronization signal, some terminals can access the cell based on the first synchronization signal, and some terminals can access the cell or obtain configuration information based on the second synchronization signal or the third synchronization signal.

[0189] Taking the association of the beam of the control channel with the broadcast channel as an example, the beam of the control channel is associated with the beam or the beam index of the broadcast channel. For example, assuming that the beam index of the broadcast channel is index i, the control channel is detected according to the index i, and the beam direction of the control channel is associated with the broadcast channel.

[0190] In some embodiments, at least one of the beam index index i of the broadcast channel, the subcarrier spacing of the broadcast channel, the starting symbol position, the slot number where it is located, and the SFN number is used to determine the position of the control channel.

[0191] Taking the association of the beam of the control channel with the first synchronization signal or the second synchronization signal as an example, the beam of the control channel is associated with the beam or the beam index of the first synchronization signal or the second synchronization signal. For example, assuming that the beam index of the second synchronization signal is index i, the control channel is detected according to the index i, and the beam direction of the control channel is associated with the second synchronization signal.

[0192] In some embodiments, at least one of the beam index index i of the synchronization signal (e.g., the first synchronization signal or the second synchronization signal), the subcarrier spacing of the synchronization signal, the starting symbol position, the slot number where the synchronization signal is located, and the SFN number is used to determine the detection position of the control channel.

[0193] The above embodiments are described by taking the determination of the detection position and the beam of the control channel according to some parameters of the synchronization signal or some parameters of the broadcast channel as an example. In some embodiments, the detection position of the control channel is specified, and the beam of the control channel is predefined. FIG. 17 is a schematic diagram of the beam association of a control channel according to an embodiment of the present disclosure. Referring to FIG. 17, in a certain slot n of each radio frame, the starting symbol is 0, and FIG. 17 shows the positions of the common search space of different beams, or the detection positions of the control channel.

[0194] In some embodiments, the monitoring period of the control channel is X ms, and in one period, the positions of the control channels of different beams transmitted in the time domain are slot-level continuous, or two control channels in one slot can be transmitted through different beams.

[0195] In some embodiments, the control channel has the same RE power as the synchronization signal, the broadcast channel, or the demodulation reference signal of the broadcast channel, or has a fixed offset.

[0196] In some embodiments, the demodulation reference signal of the control channel has the same RE power as the synchronization signal, the broadcast channel, or the demodulation reference signal of the broadcast channel, or has a fixed offset.

[0226] In some embodiments, the first shared channel and the second shared channel are associated with the same first frequency position, identifier, or index, and the second shared channel is further associated with a second frequency position, identifier, or index.

[0227] The first frequency position, identifier, or index corresponds to ID, index, or frequency position information of a super cell. The second frequency position, identifier, or index corresponds to frequency position, identifier, or index information of a virtual cell or a smaller cell.

[0228] For example, the control channel is used to indicate information of three shared channels, including a first shared channel, a second shared channel, and a third shared channel. The first shared channel is used to transmit a first SIB, the second shared channel is used to transmit a second SIB, and the third shared channel is used to transmit a third SIB. For example, refer to FIG. 18, which is a schematic diagram of a control channel scheduling multiple SIBs according to an embodiment of the present disclosure.

[0229] In some embodiments, the number of shared channels is 1, 2, 3, or 4.

[0230] In some embodiments, there is a fixed gap between the multiple shared channels. Downlink control information (DCI) in the control channel is used to indicate a starting offset, i.e., the time offset of the control channel to the first SIB.

[0231] For example, in the frequency domain, the second shared channel is distributed above and / or below the first shared channel. The first shared channel is used to transmit a first SIB, and the second shared channel is used to transmit a second SIB. The positional relationship between the first SIB and the second SIB can be as shown in FIG. 19.

[0232] For example, the second SIB is above the first SIB, i.e., the minimum frequency position of the second SIB is greater than or equal to the maximum frequency position of the first SIB, i.e., the minimum RB number of the second SIB is greater than or equal to the maximum RB number of the first SIB. Or the second SIB is below the first SIB, i.e., the maximum frequency position of the second SIB is less than or equal to the minimum frequency position of the first SIB, i.e., the maximum RB number of the second SIB is less than or equal to the minimum RB number of the first SIB.

[0233] Alternatively, the first SIB and the second SIB are continuous in the frequency domain, i.e., the RB numbers are continuous. Alternatively, the second SIB1 and the first SIB have the same time domain resources, such as the number of symbols and the number of slots.

[0234] Alternatively, refer to FIG. 19, the second SIB is distributed above and below the frequency domain of the first SIB, and at this time, the first SIB is at the middle position of the frequency domain of the second SIB. When the second SIB is mapped, the resources of the first SIB need to be skipped.

[0235] Alternatively, the first SIB and the second SIB have a time division relationship, i.e., the first SIB is before the second SIB, and the two can be continuous in the time domain or have a certain gap.

[0236] In some embodiments, the control channel is used to indicate the pattern of the SIBs. Referring to FIG. 20, a diagram illustrating the pattern of SIBs scheduled by a control channel according to an embodiment of the present disclosure is shown. It should be understood that one SIB corresponds to one shared channel, and the relative position relationship between the shared channels can be obtained by indicating the position relationship between the first SIB and the second SIB through the control channel.

[0237] The above embodiments are described by taking the example that the first shared channel is determined according to the control channel, and the second shared channel is determined according to the first shared channel. As another example, the first shared channel is determined according to the first control channel, and the second shared channel is determined according to the second control channel. In this way, the scheduling information of the second control channel is configured by the first shared channel, which facilitates flexible scheduling of the second shared channel according to the second control channel, and helps to reduce the load requirement of the first shared channel.

[0238] As shown in FIG. 21, the first control channel and the second control channel are common channels, which can be received by all different types of terminals. According to the indication of the first control channel, different types of terminals obtain the corresponding configuration related to the second control channel and detect at the related positions. In this way, different scenarios or capabilities of terminals can receive the control channel and the shared channel, so as to adapt to terminals of different scenarios or capabilities to access the network.

[0239] In some embodiments, the first shared channel is determined according to the first control channel, and the second shared channel is determined according to the second control channel, including at least one of the following cases:

[0240] The second control channel is determined according to the first shared channel or the first control channel;

[0241] The first control channel and the second control channel are determined according to the synchronization signal block, the broadcast channel or the synchronization signal;

[0242] The first shared channel and the second shared channel are determined according to the synchronization signal block, the broadcast channel or the synchronization signal;

[0243] The first control channel and the first shared channel are associated with a first frequency position, an identifier or an index, and the second control channel and the second shared channel are associated with a second frequency position, an identifier or an index.

[0244] For the mapping mode of the shared channel, the control channel or the synchronization signal block, the related technologies describe it as first in the frequency domain and then in the time domain. For example, some technologies record the following content: according to the standard, for the resource elements allocated by the PDSCH, the mapping to the resource element index (k', l) p,μWhen mapping a shared channel, a control channel, or a synchronization signal block, the mapping should be performed in the time domain first and then in the frequency domain, or the mapping of the shared channel, the control channel, or the synchronization signal block is determined according to the index of the time-frequency domain resource block.

[0245] Based on this, the embodiment of the present disclosure proposes that the mapping manner of the shared channel, the control channel, or the synchronization signal block is to perform mapping in the time domain first and then in the frequency domain, or the mapping manner of the shared channel, the control channel, or the synchronization signal block is determined according to the index of the time-frequency domain resource block.

[0246] Based on a certain time domain resource and a frequency domain resource, a time-frequency domain resource block is called, and each time-frequency domain resource block is numbered, that is, the index of each time-frequency domain resource block is obtained.

[0247] Taking the mapping manner of the shared channel as an example, the mapping manner is to perform mapping in the time domain first and then in the frequency domain, FIG. 22 is a mapping schematic diagram provided by an embodiment of the present disclosure. FIG. 22 shows three technical lines, wherein, the technical line 1 is a new mapping, the technical line 2 is a common mini SIB1, and the technical line 3 is a common control resource set 0 (common CORESET#0). It should be understood that 3000 bits are difficult to be mapped to 6 times 14 equal to 84 resource elements (REs), and at least 25 resource blocks (RBs) are required.

[0248] It should be noted that the common mini SIB1 in FIG. 22 is a SIB1 proposed by an embodiment of the present disclosure, and the common mini SIB1 is smaller than the current SIB1, and the number of bits is not more than 1000. The common mini SIB1 can indicate other SIB1.

[0249] In some embodiments, the common mini SIB1 is used to indicate some system information, including at least one of the following:

[0250] Other SIB1 related information;

[0251] Initiating an uplink reference signal, a physical random access channel (PRACH), a sounding reference signal (SRS), or other information (for example, time-frequency domain resources of an uplink wake-up signal, and location, access information);

[0252] Cell barring information, cell selection information, and cell access information.

[0253] Other SIB1 related information includes at least one of the following:

[0254] Detection location of control channel scheduling other SIB1, time-frequency domain resource (number of symbols, symbol starting position, number of frequency domain resources, frequency domain starting position, etc.), periodicity, offset;

[0255] Maximum bandwidth (e.g., based on 15KHz, 5M, 20M, 100M) or number of RBs scheduling other SIB1;

[0256] Index used to determine bandwidth or UE bandwidth that can receive SIB1 or to determine bandwidth of other SIB1;

[0257] Initiate uplink reference signal, PRACH, SRS or other information (e.g., number of preambles, subcarrier spacing of msg1, time-frequency domain location, periodicity, etc.).

[0258] In some embodiments, when the shared channel, control channel or synchronization signal block is mapped, as shown in FIG. 23, another mapping diagram provided by the embodiments of the present disclosure can first increase in frequency domain and then in time domain according to a bandwidth, and then the next bandwidth. The frequency domain resource is assumed to be N RBs, the basic frequency domain resource is M RBs, N is an integer multiple of M, or based on N / M, the index based on the basic frequency domain resource is obtained. For example, N=24, M=12, N / M=2, and the index of the basic frequency domain resource can be 0, 1.

[0259] In some embodiments, the control channel is used to indicate at least one SIB1. Different SIB1s can facilitate terminal access to the cell in different scenarios or terminal access to the cell with different bandwidth capabilities.

[0260] As an example, the control channel is used to indicate one SIB1, and the control channel indicates a flexible bandwidth SIB1. For example, the RB number supported by the SIB1 can be at least one of 6, 12, 24, 48, etc.

[0261] As another example, the control channel is used to indicate an index, and the index points to different maximum bandwidth SIB1. For example, a 2-bit index corresponds to SIB1 maximum bandwidth including 6, 12, 24, 48 RBs. The control channel is also used to schedule the RB number of the specific SIB1.

[0262] As another example, the control channel is used to indicate time-frequency domain resources of the at least one SIB1. Taking an example in which the at least one SIB1 includes a first SIB1 and a second SIB1, the control channel is used to indicate time-frequency domain resources of the first SIB1 and time-frequency domain resources of the second SIB1, for example: the control channel DCI contains a first frequency domain resource allocation field, a first time domain resource allocation field, a second frequency domain resource allocation field, and a second time domain resource allocation field. The UE receives or intervenes according to its own bandwidth.

[0263] When the control channel schedules the SIB1, if it is cross-slot scheduling, the bandwidth can be greater than 5M. If the SIB1 is scheduled in the same slot, the bandwidth is limited to a specific bandwidth or X RBs.

[0264] As another example, the control channel is used to indicate at least one system message type or at least one SIB1 type, and different system message types or different SIB1 types correspond to different system messages, frequency domain resources, or time domain resources, and different frequency domain resources can be different bandwidths.

[0265] For example, system message type 1 or SIB1 type 1 has a maximum bandwidth of 12 RBs or 24 RBs, or a maximum time domain resource of 14 symbols or 1 slot. System message type 2 or SIB1 type 2 has a maximum bandwidth of X RBs or X MHz, and a maximum time domain resource of Y symbols or Y slots.

[0266] It should be noted that the above types can also be replaced by formats. For example, the control channel used to indicate at least one system message type or at least one SIB1 type can also be referred to as the control channel used to indicate at least one system message format or at least one SIB1 format.

[0267] In some embodiments, the relationship between the synchronization signal block and the control channel satisfies at least one of the following:

[0268] The synchronization signal block and the control channel have the same center frequency point, reference frequency point, or reference time point;

[0269] The synchronization signal block and the control channel have a specific offset in the time domain;

[0270] The synchronization signal block and the control channel have the same number of time domain resources or the same number of frequency domain resources;

[0271] The synchronization signal block and the control channel have a positive integer multiple relationship in the number of time domain resources or the number of frequency domain resources;

[0272] The synchronization signal block and the control channel have the same subcarrier spacing;

[0273] The synchronization signal block and the control channel have a specific offset in power.

[0274] The number of beams of the synchronization signal block and the control channel has a positive integer multiple relationship;

[0275] The synchronization signal block and the control channel correspond to the same index or index set;

[0276] The synchronization signal block and the control channel use the same scrambling initial value or are scrambled according to the same information.

[0277] The above index includes a cell index, a beam direction index, a carrier index, etc.

[0278] In some embodiments, the relationship between the control channel and the shared channel satisfies at least one of the following:

[0279] The bandwidths of the control channel and the shared channel do not exceed a certain threshold when they are in the same slot;

[0280] The bandwidth of the shared channel is greater than or equal to the bandwidth of the control channel when they are in different slots;

[0281] The shared channel is scheduled by the control channel, and the control channel and the shared channel have the same subcarrier spacing at a certain frequency location;

[0282] The shared channel is scheduled by the control channel, and the control channel and the shared channel have different subcarrier spacings at different frequency locations;

[0283] The control channel and the first shared channel are at the same frequency location, and the control channel and the second shared channel are at different frequency locations;

[0284] The control channel is associated with a first frequency location, an identifier or an index, and the shared channel is associated with a second frequency location, an identifier or an index.

[0285] The frequency location includes a frequency band number, a frequency range, a frequency point location, a carrier number, and a cell identifier.
