[0104] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0105] In the related art, RedCap terminals (also referred to as NR RedCap terminals) may face the following problems:

[0106] (1) RedCap terminals may support narrower bandwidths, which may result in RedCap terminals being unable to access the network. Consider the initial bandwidth configured for control channel capacity and coverage. For example, eMBB is configured for 20MHz bandwidth, while NR RedCap terminals only support 10MHz bandwidth.

[0107] (2) RedCap terminals support reduced latency processing capabilities, but the default time domain resource allocation table (TDRA table) in the related art is defined according to the user equipment (UE) processing capability 1, which may cause RedCap terminals to be unable to access;

[0108] (3) RedCap terminals may face the problem of high deployment density, which will bring challenges to network capacity. If all RedCap terminals access through the same initial bandwidth part (BWP) at the same time or access through the same initial BWP as eMBB or URLLC terminals, access congestion may occur.

[0109] (4) RedCap terminals have fewer receiving antennas, so the network needs to adopt a more conservative scheduling strategy when serving such terminals. If the network follows the scheduling strategy of ordinary terminals, such as the modulation and coding order of the service channel and the aggregation level of the control channel, and schedules them according to the coverage of ordinary terminals, then RedCap terminals in the same location may not be able to demodulate correctly.

[0110] It should be noted that in the embodiments of the present application, the name RedCap or NR light terminal is for the convenience of description and represents a terminal with reduced terminal capabilities; in actual applications, the name of such terminal may not be clearly defined.

[0111] In order to better support the low bandwidth capability, lower processing delay capability, and / or fewer receiving antennas of RedCap terminals, a BWP-based RedCap service architecture is proposed. Specifically, it supports sending multiple cell defining synchronization signal blocks (cell defining SSB) in a cell, allowing different terminals to access through different SSBs and thus work on different initial BWP bandwidths. In this way, RedCap terminals and eMMBs are accessed through different SSBs and thus work on different initial BWPs. Specifically, Figure 1As shown, the cell access method includes: the terminal performs SSB search, at this time, different types of terminals use different SSBs to obtain cell synchronization; after obtaining cell synchronization, according to CORESET#0 indicated by PBCH in the SSB, that is, the initial BWP, further obtains the system message, and performs the corresponding random access operation on the corresponding initial ULBWP; that is, different types of terminals can receive system messages through different initial BWPs, thereby accessing through different initial uplink BWPs (initial UL BWPs).

[0112] Among them, in the related technology, the following two mechanisms can be used by operators to perform cell reservation and access restriction:

[0113] The first mechanism uses cell status indication or special reservation to control the cell selection and reselection process; for example, the Bar indication in the Master Information Block (MIB) message;

[0114] The second mechanism is the Unified Access Control (UAC) mechanism, which can prevent terminals of certain access categories or access identities from initiating random access to achieve purposes such as load control.

[0115] In addition, closed access group (CAG) technology can also be used to perform cell reservation and access restriction; specifically, the cell will broadcast its CAG ID, and the user determines whether to access the current cell based on his or her CAG list (CAG list).

[0116] From the above description, it can be seen that under the BWP architecture that sends multiple SSBs, if the terminal follows the existing cell search process, both the RedCap terminal and the ordinary terminal may access the cell from the SSB reserved for the other party, and then the initial BWP. On the other hand, from the perspective of terminal capabilities, the capabilities of ordinary terminals such as eMBB terminals are higher than those of RedCap terminals. Therefore, under normal circumstances, if no special treatment is made, ordinary terminals can access the BWP of RedCap terminals. However, for terminals that access the BWP of RedCap terminals, the operation of allowing them to work on a smaller bandwidth (that is, these terminals support 20M bandwidth, but access to 10M bandwidth) has not been fully tested, so problems may occur after these terminals are allowed to access the BWP of RedCap terminals. In addition, for RedCap terminals, the network scheduling strategy will also be different from that of ordinary terminals. For example, due to the reduced terminal capabilities, a more conservative scheduling strategy may be used under the same channel conditions. In this way, it is not very friendly to ordinary terminals, so when accessing the BWP of RedCap terminals, the transmission efficiency will also be reduced. In addition, in some cases, if the network knows that the terminal capabilities in the current area can coexist with ordinary terminals, only one public SSB can be used for terminal access, thereby reducing network overhead.

[0117] Therefore, how to control the access of different terminal types according to network needs is a problem that needs to be solved urgently.

[0118] In order to solve the above problems, the most direct implementation method is to use the bar information indication in the MIB message in the PBCH, and then add some additional indications, so that ordinary terminals can only recognize the Bar information, and RedCap terminals need to look at the content of the additional indication information after recognizing the bar, so as to determine whether to prohibit this type of special terminal. However, the design of the Bar information indication is to directly prohibit all terminals from the perspective of the cell. If this method is only opened for RedCap terminals, this method does not meet the original intention of the design.

[0119] Based on this, in various embodiments of the present application, by indicating the scrambling parameters, interleaving parameters, and time-frequency domain resource determination method when the terminal accesses the cell, the network side can reasonably adjust the indication information according to the terminal capabilities and network load conditions, etc., to achieve the coexistence of RedCap terminals and ordinary terminals or the independent access of the two terminals.

[0120] The present application embodiment provides an information determination method, which is applied to a terminal, such as Figure 2 As shown, the method includes:

[0121] Step 201: Receive first information, where the first information indicates at least one of the following information:

[0122] Interleaving parameters of CORESET#0;

[0123] The scrambling parameter value when the network is not configured with the PDCCH scrambling parameter pdcch-DMRS-ScramblingID;

[0124] Method for determining time domain resources;

[0125] Frequency domain resource determination method;

[0126] Step 202: Using the first information, determine the second information required by the terminal to receive information and / or transmit information; the second information includes at least one of the following:

[0127] Interleaving functions;

[0128] scrambling sequence;

[0129] Time domain resources;

[0130] Frequency domain resources.

[0131] Among them, in actual application, for RedCap terminals, when the network side allows RedCap terminals to access independently, the RedCap terminal-specific interleaving method can be used. In this way, ordinary terminals cannot obtain SIBs and cannot access the initial BWP reserved for RedCap terminals.

[0132] In actual application, each control resource set (CORESET) corresponds to a mapping method of control channel element (CCE, ControlChannel Element) to resource element group (REG, Resource Element Group). CCE is the unit of PDCCH, and the interleaving unit is REG bundle. Each REG bundle includes L REGs. The number of REG bundles contained in CORESET is in, Indicates the number of REGs contained in each CORESET, which is the product of the number of RBs and the number of symbols contained in the CORESET, that is,

[0133] The REG bundle contained in CCE j is {f(6j / L),f(6j / L+1),...,f(6j / L+6 / L-1)}, and the f(·) function depends on the CCE to REG mapping mode of CORESET. For the non-interleaved mode, that is, the mapping of non-interleaved CCE to REG, L=6, f(x)=x; for the interleaved mode, that is, the mapping of interleaved CCE to REG, Where x = cR + r, r = 0, 1..., R-1, c = 0, 1..., C-1, n shift Represents an offset parameter, R is given by the high-level parameter interleaverSize, and mod represents the remainder.

[0134] In actual application, when the high-level parameter shift index (shiftIndex) is configured, n shift Given by the high-level parameter shiftIndex; when the high-level parameter shiftIndex is not configured,

[0135] From the above description, it can be seen that in the mapping method of interleaving CCE to REG, all REGbundles of a CCE are written in rows and read out in columns, only an offset parameter n is added. shift .

[0136] For CORESET#0 (also called CORESET 0), its size is configured through PBCH, and the interleaving mode is adopted by default. The values ​​of the relevant parameters in the interleaving mode include:

[0137] L = 6;

[0138] R = 2;

[0139]

[0140] in, Indicates the physical layer cell ID.

[0141] Therefore, different n can be defined for RedCap terminals and normal terminals. shift value to implement access control.

[0142] Based on this, in one embodiment, when the first information indicates the interleaving parameters of CORESET#0, that is, when the first information indicates the interleaving parameters of CORESET#0, the first information satisfies one of the following:

[0143] The interleaving parameter n indicated by the first information shift The value of is different from Or the first information indicates the interleaving parameter n shift Is the value different from

[0144] The interleaving parameter n indicated by the first information shift The value of The first offset value is introduced based on the first information indicating the interleaving parameter nshift The value of Whether to introduce the first offset value based on the

[0145] Exemplarily, for a common terminal, the interleaving parameter n shift The value of For RedCap terminals, the interleaving parameter n shift The value of is: On the basis of, add an offset value, expressed by the formula Wherein, A1 represents the first offset value. In this case, if the network only requires RedCap terminal access, when the interleaving parameter n indicated by the first information is shift The value of is different from Or the interleaving parameter n indicated by the first information shift The value of When the first offset value is introduced on the basis of the original CCE, the ordinary terminal cannot obtain the correct CCE in the original way, and thus cannot read the type0-PDCCH. Therefore, according to the implementation of the relevant technology, the SIB cannot be obtained. Then for these ordinary terminals, it will be considered that the cell corresponding to the current SSB is the barred cell, while the RedCap terminal can obtain the correct CCE. In this way, the ordinary terminal is controlled to be unable to access the initial BWP reserved for the RedCap terminal, that is, it cannot access the cell through the initial BWP reserved for the RedCap terminal.

[0146] In actual application, when the first information indicates the interleaving parameter n shift Is the value different from When a bit is set in PBCH, for example, when the bit is set to 1, it indicates that the interleaving parameter n shift The value of is different from This means that the interleaving method exclusive to the RedCap terminal is used. When this bit is set to 0 or default, it indicates that the interleaving parameter n shift The value of is This means that the interleaving method common to ordinary terminals is used; of course, this bit can also be set to 0 or default, indicating that the interleaving parameter n shift The value of is When this bit is set to 1, it indicates that the interleaving parameter n shift The value of is different from

[0147] When the first information indicates the interleaving parameter n shift The value of When the first offset value is introduced based on the value of n, a bit can be set in the PBCH. For example, when the bit is set to 1, it indicates that the interleaving parameter n shiftThe value of The first offset value is introduced on the basis of the RedCap terminal, which means that the interleaving method exclusive to the RedCap terminal is used. When this bit is set to 0 or default, it means that the interleaving parameter n shift The value of is not in The first offset value is introduced on the basis of This means that the interleaving method common to ordinary terminals is used; of course, the bit can also be set to 0 or default, indicating that the interleaving parameter n shift The value of The first offset value is introduced based on the bit. When this bit is set to 1, it indicates that the interleaving parameter n shift The value of is not in A first offset value is introduced based on .

[0148] When the first information indicates the interleaving parameter n shift The value of is different from When the terminal can adopt To determine the interleaving parameter n shift When the first information indicates the interleaving parameter n shift The value of When the first offset value is introduced based on To determine the interleaving parameter n shift The value of .

[0149] In actual application, for RedCap terminals, when the network side allows RedCap terminals to access independently, a different scrambling sequence from that of ordinary terminals can be used. In this way, ordinary terminals cannot obtain PDCCH and cannot access the initial BWP reserved for RedCap terminals.

[0150] The bits carried by the PDCCH are b(0),...,b(M bit -1) Before modulation, scrambling is required, that is,

[0151]

[0152] The sequence generator of the scrambling sequence c(i) is initialized using the following formula:

[0153] c init =(n RNTI 2 16 +n ID )mod2 31 ;

[0154] Among them, for the initial access phase, when the dedicated RRC parameters have not been configured, that is, when the PDCCH scrambling parameter pdcch-DMRS-ScramblingID is not configured,

[0155]

[0156] n RNTI =0.

[0157] When the PDCCH scrambling parameter pdcch-DMRS-ScramblingID is configured, n ID The value is PDCCH scrambling parameter pdcch-DMRS-ScramblingID, n RNTI The value is the Cell Radio Network Temporary Identifier (C-RNTI).

[0158] Therefore, for RedCap terminals and common terminals, different scrambling sequence initialization parameters can be introduced or different scrambling sequence initialization values ​​can be defined to implement access control.

[0159] Based on this, in one embodiment, when the first information indicates a scrambling parameter value when the network does not configure the PDCCH scrambling parameter, that is, when the first information indicates a scrambling parameter value when the network does not configure the PDCCH scrambling parameter, the first information indicates one of the following:

[0160] Indicates the introduction of division n when generating the initial value of the scrambling sequence RNTI and n ID A parameter other than n, or indicates whether to introduce a parameter other than n when generating the initial value of the scrambling sequence RNTI and n ID An additional parameter;

[0161] Indicates that the initial value of the scrambling sequence is different from c init =(n RNTI 2 16 +n ID )mod2 31 The value of, or indicates whether the initial value of the scrambling sequence is different from c init =(n RNTI 2 16 +n ID )mod2 31 The value of

[0162] Indicates the parameter n for generating the initial value of the scrambling sequence ID The value of A second offset value is introduced based on the value of the scrambling sequence, or a parameter n indicating the initial value of the scrambling sequence is generated. ID The value of Whether to introduce a second offset value based on

[0163] Indicates the parameter n for generating the initial value of the scrambling sequence ID The value is different from The value of, or the parameter n indicating the initial value of the generated scrambling sequence ID Is the value of different from The value of

[0164] Indicates the parameter n for generating the initial value of the scrambling sequence RNTI The value of is non-zero, or indicates the parameter n that generates the initial value of the scrambling sequence RNTI Is the value of is non-zero.

[0165] Exemplarily, for a common terminal, the above formula is used to generate the initial value of the scrambling sequence; for a RedCap terminal, a parameter for generating the initial value of the scrambling sequence different from that of a common terminal is used, such as ID ,exist On the basis of, add an offset value, expressed by the formula For example, for n RNTI , is a non-zero value (which can be determined as needed); for example, directly adding a variable X to the initial sequence generation formula. In this case, if the network only requires RedCap terminals to access, ordinary terminals use the original scrambling sequence of eMBB for descrambling, so they cannot obtain PDCCH, and thus the cell corresponding to the current SSB is considered to be a barred cell, while the RedCap terminal can obtain PDCCH. In this way, ordinary terminals are controlled to be unable to access the initial BWP reserved for RedCap terminals, that is, they cannot access the cell through the initial BWP reserved for RedCap terminals.

[0166] Wherein, when the first information indicates that the initial value of the scrambling sequence is different from c init =(n RNTI 2 16 +n ID )mod2 31 When the value of To determine n ID value, or n RNTI Use a non-zero value or introduce a division by n when determining the initial value of the scrambling sequence RNTI and n ID For example, the following formula is used to determine the initial value of the scrambling sequence:

[0167] c init =(n RNTI 2 16 +n ID +X)mod2 31 ;

[0168] Where X represents the number of n RNTI and nID The third parameter outside.

[0169] Here, in actual application, the embodiment of the present application does not limit the process of introducing the third parameter to determine the initial value of the scrambling sequence.

[0170] When the first information indicates parameter n ID The value is different from When taking the value of To determine the parameter n ID The value of .

[0171] When the first information indicates parameter n RNTI When the value of is non-zero, a non-zero value (such as an agreed value) is used to determine the parameter n RNTI The value of .

[0172] In actual application, when the first information indicates whether to introduce the division n when generating the initial value of the scrambling sequence RNTI and n ID When a parameter other than n is used, a bit can be set in the PBCH. For example, when the bit is set to 1, it indicates that the initial value of the scrambling sequence is generated by introducing a parameter other than n. RNTI and n ID A parameter other than n indicates that the RedCap terminal exclusive scrambling method is used. When this bit is set to 0 or default, it means that no scrambling sequence is introduced when generating the initial value of the scrambling sequence. RNTI and n ID Of course, this bit can also be set to 0 or default, indicating that the scrambling method other than n is introduced when generating the initial value of the scrambling sequence. RNTI and n ID When this bit is set to 1, it means that no parameters other than n are introduced when generating the initial value of the scrambling sequence. RNTI and n ID An additional parameter.

[0173] When the first information indicates whether the initial value of the scrambling sequence is different from c init =(n RNTI 2 16 +n ID )mod2 31 When the value of c is set, a bit can be set in PBCH. For example, when the bit is set to 1, it means that the initial value of the scrambling sequence is different from c. init =(n RNTI 2 16 +n ID )mod2 31 The value of indicates that the RedCap terminal exclusive scrambling method is used. When this bit is set to 0 or default, it means that the initial value of the scrambling sequence is cinit =(n RNTI 2 16 +n ID )mod2 31 , which means that the scrambling method common to ordinary terminals is used. Of course, this bit can also be set to 0 or default, indicating that the initial value of the scrambling sequence is different from c init =(n RNTI 2 16 +n ID )mod2 31 When this bit is set to 1, it indicates that the initial value of the scrambling sequence is c init =(n RNTI 2 16 +n ID )mod2 31 .

[0174] When the first information indicates the parameter n for generating the initial value of the scrambling sequence ID The value of When the second offset value is introduced based on the parameter n, a bit can be set in the PBCH. For example, when the bit is set to 1, it indicates that the parameter n ID The value of The second offset value is introduced on the basis of the RedCap terminal, which means that the RedCap terminal exclusive scrambling method is used. When this bit is set to 0 or default, it means that the parameter n ID The value of is not in The second offset value is introduced on the basis of , that is, the second offset value is not introduced, which means that the scrambling method common to ordinary terminals is used. Of course, it can also be that when this bit is set to 0 or default, it means that the parameter n ID The value of The second offset value is introduced based on the bit. When this bit is set to 1, it means that the parameter n ID The value of is not in A second offset value is introduced based on .

[0175] When the first information indicates the parameter n for generating the initial value of the scrambling sequence ID Is the value of different from When the value of parameter n is taken, a bit can be set in PBCH. For example, when the bit is set to 1, it means that the parameter n ID The value is different from The value of indicates that the RedCap terminal exclusive scrambling method is used. When this bit is set to 0 or default, it indicates that the parameter n ID The value of This means that the scrambling method used by ordinary terminals is used. Of course, this bit can also be set to 0 or default, indicating that the parameter n ID The value is different from When this bit is set to 1, it indicates that the parameter n ID The value of

[0176] When the first information indicates the parameter n for generating the initial value of the scrambling sequence RNTI When the value of is non-zero, a bit can be set in PBCH. For example, when the bit is set to 1, it indicates that the parameter n RNTI The value of is non-zero, which means that the RedCap terminal-specific scrambling method is used. When this bit is set to 0 or default, it means that the parameter n RNTI The value of is zero, which means that the scrambling method common to ordinary terminals is used. Of course, this bit can also be set to 0 or default, indicating that the parameter n RNTI The value is non-zero. When this bit is set to 1, it means that the parameter n RNTI The value of is zero.

[0177] In actual application, type0-PDCCH carries the time-frequency domain resource scheduling information for PDSCH carrying SIB messages. The time-domain resource scheduling information carries the offset value of the physical downlink shared channel (PDSCH) and / or physical uplink shared channel (PUSCH) time slots scheduled by PDCCH relative to PDCCH, which are the time slot offset value k0 of PDSCH and the time slot offset value k2 of PUSCH.

[0178] Therefore, for RedCap terminals and ordinary terminals, different interpretations can be made through the time-frequency domain resource scheduling of type0-PDCCH to achieve access control.

[0179] Based on this, in one embodiment, when the first information indicates a time domain resource determination method, that is, when the first information indicates a time domain resource determination method, the first information indicates one of the following:

[0180] Indicate whether to introduce a third offset value on the transmission time slot indicated by the time domain resource assignment (which can be expressed as Time domain resource assignment in English) field in the DCI, or indicate to introduce a third offset value on the transmission time slot indicated by the time domain resource assignment field in the DCI;

[0181] Indicates whether to use a specific default Time Domain Resource Allocation (TDRA) table to determine the transmission time slot, or indicates to use a specific default TDRA table to determine the transmission time slot.

[0182] Here, when the first information indicates that a third offset value is introduced in the transmission time slot indicated by the time domain resource allocation field in the DCI, the first information does not indicate the value of the third offset value, that is, the first information does not indicate the transmission time slot corresponding to the terminal, that is, the first information only indicates whether an offset value is introduced in the transmission time slot indicated by the time domain resource allocation field in the DCI. At this time, in actual application, a new PDSCH TDRA table can be defined for RedCap terminals. When the first information indicates that an offset value is introduced in the transmission time slot indicated by the time domain resource allocation field in the DCI, the new TDRA table is used to determine the time domain resources required for the terminal to receive information and / or transmit information. Exemplarily, in the new TDRA table, on the basis of obtaining the k0 and / or k2 values ​​according to the transmission time slot indicated by the time domain resource allocation field in the DCI, an offset value X is added, such as k0=0 indicated in the DCI carried by the PDCCH, and for the RedCap terminal, k0 is defaulted to the indicated k0+1=1. In this case, if the network only requires RedCap terminals to access, when the first information indicates the introduction of an offset value on the transmission time slot indicated by the time domain resource allocation field in the DCI, the scheduling information for the RedCap terminal will not be received by the ordinary terminal. For these ordinary terminals, the access is considered to be Bar. In this way, the ordinary terminal is controlled to be unable to access the initial BWP reserved for the RedCap terminal, that is, it cannot access the cell through the initial BWP reserved for the RedCap terminal.

[0183] For the offset in the time domain, before the radio resource control (RRC) accesses, for example, before the uplink is not configured with a PUSCH time domain allocation table (which can be expressed as pusch-TimeDomainAllocationList in English) or before the PUSCH time domain resource allocation table that uses the configuration is not available, the terminal uses a predefined default TDRA table, as shown in Table 1, to confirm the values ​​of k0 and k2. Specifically, the terminal confirms the values ​​of k0 and k2 in combination with the index (index) indicated by the time domain resource allocation domain in the DCI and the default TDRA table.

[0184]

[0185]

[0186] Table 1

[0187] In actual application, an independent TDRA table can be defined for a certain type of terminal. In the related art, in the uplink, the values ​​shown in Table 1 are candidate values ​​for the time domain resource allocation of PUSCH in DCI. For the downlink, some cases where the default TDRA table is used are also defined. In this case, for ordinary terminals, the values ​​shown in Table 1 can be used, and for RedCap terminals (a specific type of terminal), another default TDRA table, i.e., a specific default TDRA table, can be defined in the uplink; in the downlink, a default TDRA table different from that of ordinary terminals can also be defined. In this case, if the network only requires RedCap terminals to access, that is, the first information indicates the use of a specific default TDRA table (that is, the default TDRA table corresponding to the RedCap terminal) to determine the transmission time slot, according to the index indicated by the DCI time domain resource allocation domain, the traditional terminal and the RedCap terminal will obtain different k0 and / or K2 values, and the scheduling information for the RedCap terminal will not be received by the ordinary terminal. For these ordinary terminals, the access is considered to be Bar. In this way, the ordinary terminal is controlled to be unable to access the initial BWP reserved for the RedCap terminal, that is, it cannot access the cell through the initial BWP reserved for the RedCap terminal.

[0188] In actual application, when scheduling through DCI format 1-0, continuous resource allocation mode and downlink resource allocation mode 1 are used. Therefore, the terminal determines the starting resource block (RB) position and continuous RB length of PDSCH through the frequency domain resource allocation (which can be expressed as Frequency domain resourceassignment) domain. Therefore, for frequency domain resource scheduling, access control for different types of terminals can be achieved by adding an RB offset value.

[0189] Based on this, in one embodiment, when the first information indicates a method for determining frequency domain resources, the first information indicates whether to introduce a fourth offset value at the frequency domain resource position indicated by the frequency domain resource allocation field in the DCI, or indicates to introduce a fourth offset value at the frequency domain resource position indicated by the frequency domain resource allocation field in the DCI.

[0190] Exemplarily, if the network only requires RedCap terminal access, that is, when the first information indicates the introduction of a fourth offset value at the frequency domain resource position indicated by the frequency domain resource allocation domain in the DCI, ordinary terminals cannot obtain system information, that is, cannot obtain the system information of the RedCap terminal. In this way, ordinary terminals are controlled to be unable to access the initial BWP reserved for the RedCap terminal, that is, they cannot access the cell through the initial BWP reserved for the RedCap terminal.

[0191] When the first information indicates whether to introduce a fourth offset value in the frequency domain resource position indicated by the frequency domain resource allocation field in the DCI, a bit can be set in the PBCH. For example, when the bit is set to 1, it indicates that the fourth offset value is introduced in the frequency domain resource position indicated by the frequency domain resource allocation field in the DCI. When the bit is set to 0 or default, it indicates that the fourth offset value is not introduced in the frequency domain resource position indicated by the frequency domain resource allocation field in the DCI, that is, the fourth offset value is not introduced.

[0192] In actual application, the first information may be carried in the PBCH, that is, the first information is received through the PBCH. Specifically, it may be implemented in the following ways:

[0193] First, there is a high-level reserved bit (in sparse state) in the MIB message carried by the PBCH, and the first information can be set through the reserve bit;

[0194] The second type is that for the upper three bits of the SSB index in the PBCH, these three bits are used to send indications of up to 64 SSBs in frequency range 2 (FR2) (i.e., millimeter wave frequency band); and since the SSB index is only up to 7 in frequency range 1 (FR1) (frequency band below 6GHz), it has been completely determined by the DMRS of the PBCH, and the upper three bits are not needed. Therefore, for FR1, these three bits are not needed, but one of them is used in combination with the subcarrier offset (ssb-SubcarrierOffset) parameter to indicate the subcarrier-level offset between the physical resource block (PRB) carrying the SSB and the carrier PRB, which has been used in low frequencies. Therefore, for FR1, there are still 2 bits that are not used; therefore, these 2 bits can be used for indication, that is, the first information is set by these 2 bits.

[0195] That is to say, all of the above bits can be used to achieve the purpose of indication, such as indicating through 1 bit of PBCH, that is, setting the first information.

[0196] From the above description, it can be seen that the solution provided in the embodiment of the present application realizes access control of the cell by establishing a relationship between the bit information in the PBCH and the scrambling parameters, interleaving parameters, and time-frequency domain resource determination method when the terminal accesses the cell, thereby enabling the RedCap terminal to coexist with ordinary terminals through independent BWP access or public BWP access.

[0197] In actual application, when the first information indicates the interleaving parameters of CORESET#0, the second information includes the interleaving function; when the first information indicates the scrambling parameter value when the network is not configured with the PDCCH scrambling parameter pdcch-DMRS-ScramblingID, the second information includes the scrambling sequence; when the first information indicates the time domain resource determination method, the second information includes the time domain resources; when the first information indicates the frequency domain resource determination method, the second information includes the frequency domain resources.

[0198] In actual application, in the embodiment of the present application, the network side may also enable the terminal so that the terminal implements the solution of the embodiment of the present application.

[0199] Based on this, in one embodiment, the method may further include:

[0200] Receive third information; the third information indicates whether the terminal uses the second information of a specific type of terminal.

[0201] Here, the second information of the specific type of terminal may also be referred to as the second information of the specific terminal type, which may be determined as needed, and may be a RedCap terminal or a common terminal.

[0202] When the third information indicates that the terminal uses the second information of a specific type of terminal, the terminal determines the second information by using the received first information.

[0203] Here, in actual application, the third information is carried in the PBCH. That is, the third information is received through the PBCH, that is, when the third information is received, the third information is obtained through the PBCH. Exemplarily, one bit can be set in the PBCH, and when the bit is set to 0 or default, it indicates that the second information of the specific type of terminal is not used; when the bit is set to 1, it indicates that the second information of the specific type of terminal is used.
