Description

Resource position determining method and device

Technical Field

The present application relates to the field of network technologies, and in particular, to a method and an apparatus for determining a resource location.

Background

As technology evolves, the available frequency bands continue to increase. The New Radio (NR) access technology divides the frequency band into two parts, namely a frequency domain range 1 (FR 1) and FR2, wherein FR2 mainly refers to a bandwidth of 450 MHz-6 GHz and FR2 mainly refers to a bandwidth of 24.25 GHz-52.6 GHz. In addition, the frequency band of 52.6GHz to 70GHz (abbreviated as above 52.6 GHz) is also being incorporated into the application range of the next generation mobile communication system (beyond 5.5G system). The definition of subcarrier spacing (SCS) or numerical value (numerology) of different frequency bands is different, the corresponding frame structure length is also different, and different numerical value settings realize that NR supports the requirements of multiple services at the same time. At present, SCS supportable by FR1 frequency band is 15KHz and 30KHz. SCS supportable by FR2 frequency band are 60KHz,120KHz and 240KHz. For the above 52.6GHz band, according to the latest conference result of RAN1_103 times, 2 SCSs are supported in minimum among {240kHz,480kHz,960kHz } in addition to the SCS of 120kHz being forcedly supported, but the SCS supported in total is not more than 3.

Since after introducing a new SCS, in the SCS combining manner of different synchronization signal blocks (synchronization signal block, SSB) and common resource blocks (common resource block, CRB), the value of the offset Kssb of the lowest frequency domain position of the SSB relative to the starting position of the first subcarrier in the CRB will change, so that the User Equipment (UE) cannot accurately detect the SSB.

Detailed Description

Embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

As shown in fig. 1, fig. 1 is a schematic architecture diagram of a communication system 100 according to an embodiment of the present application. The communication system 100 may include a network device 110 and terminal devices 101-106.

In the communication system 100, the network device 110 may transmit downlink data to the terminal devices 101 to 106. Of course, the terminal devices 101 to 106 may transmit uplink data to the network device 110. Terminal devices 101-106 may be UEs, car communicators, cellular telephones, smartphones, laptops, handheld communicators, handheld computing devices, satellite radios, global positioning systems, palm top computers (personal digital assistant, PDAs), and/or any other suitable device for communicating over wireless communication system 100, etc. The communication system 100 may employ a public land mobile network (public land mobile network, PLMN), an internet of vehicles (vehicle to everything, V2X), a device-to-device (D2D) network, a machine-to-machine (machine to machine, M2M) network, an internet of things (internet of things, ioT), or other network. In addition, the terminal devices 104 to 106 may constitute a communication system. In the communication system, the terminal device 105 can transmit downlink data to the terminal device 104 or the terminal device 106. The method in the embodiment of the present application may be applied to the communication system 100 shown in fig. 1.

The application is mainly applied to a mobile communication system working in a shared frequency band, and is mainly oriented to an above 52.6GHz frequency band, such as a 60GHz shared frequency band.

For the above 52.6GHz frequency band, both an authorized frequency band and an unauthorized frequency band exist. Unlicensed bands may also be referred to as shared bands. In the background framework of the fifth generation mobile communication technology, technologies deployed in the shared frequency band are collectively referred to as wireless unlicensed frequency band technologies (new radio unlicensed, NRU). On the shared frequency band, other systems such as radar (radar), wireless-fidelity (wifi), bluetooth and other heterogeneous operator access systems are included in addition to the NR system, so it is specified that the system operating on the shared frequency band needs to support all or part of the following key technologies: listen-before-talk (listen before talk, LBT), transmit power control (transmit power control, TPC) and dynamic spectrum selection (dynamic frequency selection, DFS). The LBT mechanism refers to that various access devices need to acquire interference conditions on a frequency band where a target channel is located before using the channel, and only when the interference level on the target channel is not greater than a preset threshold value, the target channel can be used. The TPC mechanism refers to that in order not to affect the normal communication situation of other access devices, the transmitting device operating on the shared grant cannot raise its own transmit power without limitation. The DFS mechanism is used for dynamically switching to a frequency band with lower interference to work when the system needs to timely avoid the frequency band where the high priority system is located when working on the shared authorization.

However, for receiving devices accessing different types of frequency bands, such as User Equipment (UE), the synchronization information block pattern (synchronization signal block pattern, SS/PBCH Block Pattern/SSB) transmitted from the base station (gNB, gndeb) is first detected. As shown in fig. 2, fig. 2 is a schematic diagram of an SSB. SSB may consist of a synchronization signal primary synchronization signal (primary synchronization signal, PSS), a secondary synchronization signal (secondary synchronization signal, SSS) and a physical broadcast channel (physical broadcast channel, PBCH), consisting of a two-dimensional region of 4 orthogonal frequency division multiplexing symbols (orthogonal frequency division multiplexing, OFDM) in the time domain and 20 Resource Blocks (RBs) in the frequency domain. The UE can accomplish cell synchronization and coarse symbol-level timing synchronization by demodulating PSS and SSS. The PBCH carries main information block (master information block, MIB) information from higher layer configuration, timing synchronization of system frame level can be completed by demodulating MIB information, relevant configuration information of system information block 1/residual minimum system information (system information block/remaining minimum system information, SIB 1/RMSI) is obtained, namely, type 0-physical downlink control channel (physical downlink control channel, type 0-PDCCH) and physical downlink shared channel (physical downlink shared channel, PDSCH) of SIB1/RMSI is demodulated through a field (PDCCH-ConfigSIB 1), and a control resource set (control resource set, COESET) #0 is located in the Type 0-PDCCH.

The MIB is carried in the PBCH channel in the SSB, which may include a "systemFrameNumber" field, representing the lower 6 bits of the system frame; the "subclrierspacengcommon" field, which indicates the subcarriers of SIB1, message (Msg) 2/4 and other system information (other system information, OSI); the "SSB-subbrieroffset" field indicates the offset between SSB and subcarrier #0 in the common resource block (common resource block, CRB); a "DMRS-type a-Position" field, indicating the Position of the first demodulation reference signal (demodulation reference signal, DMRS); the "PDCCH-ConfigSIB1" field, which indicates the parameter configuration of CORESET, search space and related PDCCH; a "cellBarred" field, indicating whether the UE is allowed to access the cell; an "intra freqreselection" field, indicating cell selection or reselection by the UE within an intra-frequency measurement (intra-frequency); the "spare" field is a temporarily unused legacy bit.

Systems operating in the licensed band and the shared band, the same fields in the MIB represent different contents. Specifically, for systems operating on a shared frequency band, the base station cannot transmit a specified SSB at a specified location in view of the existence of the LBT mechanism. Thus newly defining a Q value, i.e Represented by 2 bits, take the values 1,2,4, 8. The UE may calculate and obtain multiple candidate locations for transmitting the same SSB index by demodulating the Q value and according to the DMRS sequence, where the multiple candidate locations are interpreted by the UE as having the same quasi co-location (QCL) relationship, e.g., corresponding to the same downlink beam direction.

After acquiring the target frequency point, the UE initially accessing the cell searches for SSBs in units of a synchronization fence (sync timer) on the frequency domain. After searching for a suitable SSB in the frequency domain, the UE obtains Kssb by demodulating SSB calculation. Where Kssb denotes a space between the lowest frequency domain position of the SSB in the RB overlapping with the CRB and the subcarrier index #0 in the CRB.

As shown in fig. 3, fig. 3 is a schematic diagram of SSB-CRB spacing. The "absoltatfrequencypinta" field 3, the "offsettopoiinta" field 1, and the "absoltatfrequencyssb" field 2 are all stored in SIB 1. The "absoltatfrequencypinta" field 3 indicates an absolute frequency domain position of the reference RB (crb#0), the "absoltatfrequencypssb" field 2 indicates an absolute frequency domain position of the SSB, the "offsettopinta" field 1 indicates a frequency domain deviation between the data channel and the poiinta, which is a position of the subcarrier #0 on crb#0.

The system operating in FR1 has a Kssb value of 0 to 31, by means of the "ssb-subsearrieroffset" field of 4-bits+1-bit (PBCH payload:) Indicating, a total of 5-bits.The system operating in FR2 has Kssb values of 0-15, indicated by the "ssb-SubcarrierOffset" field, expressed in total 4-bits. The Kssb values are related to SCS between SSB and CRB, and are shown in table 1 for different frequency bands.

TABLE 1

It should be noted that, for the UE, the default demodulated SSB is a cell-defined SSB (CD-SSB). The CD-SSB contains necessary information for the UE for initial access, e.g. related configuration information indicating the transmission of SIB 1/remaining minimum system information (remaining minimum system information, RMSI). Contrary to CD-SSB, non-CD SSB is mainly used for radio resource management (radio resource management, RRM), the PBCH in Non-CD SSB does not directly indicate RMSI PDCCH the search space, i.e. the UE cannot camp on or access the target cell through such SSB. The primary consideration of the present application is to determine the location of the CD-SSB.

As also shown in Table 1, for the FR1 system, when the SCS of the SSB is 15kHz and the SCS of the CRB is 30kHz, the value of Kssb is larger, and the value range of Kssb is 0-23. In the case where SCS of SSB and SCS of CRB are (30 kHz,15 kHz), kssb has a value range of only 0-5. For the FR2 system, because SCS of SSB is larger than SCS of CRB, kssb has the largest value range of 0-11, namely when SCS of SSB and SCS of CRB meet (120 kHz ). For a system operating in the shared band (NRU system), the low order bits (LSB of SSB-subsearrier offset) in the "SSB-subsearrier offset" field and the "subsearrier spacing comm" field are used to indicate the Q value, so the placement of SSB or the calculation formula of Kssb is: As shown in the table 2 below,and K is equal to _SSB Is a relationship of (3).

TABLE 2

Wherein,the value range of (2) is 0-23, K _SSB The value of (2) is an even number in the range of 0-22.

R17 is standardizing the above 52.6GHz band, and SCS, which determines SSB and CRB are also one of the main discussion points at present. The SCS of 120kHz will also select two of the {240kHz,480kHz,960kHz } as optional subcarriers, in addition to the mandatory. Since after introducing a new SCS, in the SCS combination of different SSBs and CRBs, the value of the offset Kssb of the lowest frequency domain position of the SSB relative to the starting position of the first subcarrier in the CRB is changed, so that the UE cannot accurately detect the SSB. In order to solve the technical problems, the embodiment of the application provides the following solutions.

Fig. 4 is a flow chart of a method for determining a resource location according to an embodiment of the present application, as shown in fig. 4. The steps in the embodiment of the application at least comprise:

s401, a first subcarrier spacing SCS of the synchronization signal block SSB and a second subcarrier spacing SCS of the common resource block CRB are acquired.

Wherein the first subcarrier spacing SCS may be 120kHz, 240kHz,480kHz or 960kHz. The second subcarrier spacing SCS may be 120kHz, 240kHz,480kHz or 960kHz. The different SCS combinations of SSB and CRB may include: when the first SCS is 120kHz and the second SCS is 480kHz, or the first SCS is 240kHz and the second SCS is 960kHz, or the first SCS is 120kHz and the second SCS is 960kHz. Alternatively, the first SCS is 480kHz and the second SCS is 120kHz, or the first SCS is 960kHz and the second SCS is 240kHz, or the first SCS is 960kHz and the second SCS is 120kHz. But are not limited to, the combinations described above.

It should be noted that for the above 52.6GHz band, SSB and CRB may support at least 2 SCSs among 240kHz, 480kHz and 960kHz in addition to 120 kHz.

S402, determining, according to the first SCS and the second SCS, a value of an offset Kssb of a lowest frequency domain position of the SSB with respect to a start position of a first subcarrier (subcarrier # 0) in the CRB, where the value of Kssb is used to determine a resource position of the SSB, and the value of Kssb is indicated by a subcarrier offset (SSB-subcarrier offset) field in the SSB and a system frame number (system frame number, SFN) field in a physical broadcast channel PBCH load (payload), or by a subcarrier offset (SSB-subcarrier offset) field in the SSB and a PDCCH configuration system information block1 (system information block, SIB 1) (PDCCH-ConfigSIB 1) field in the SSB, or by 1 bit or 2 bit in a subcarrier offset (SSB-subcarrier offset) field in the SSB.

The fields in the embodiments of the present application may also be referred to as parameters, such as "ssb-subsuccrierOffset" parameters, "pdcch-ConfigSIB1" parameters, and so on.

Optionally, determining the value of the Kssb according to a configuration unit of the SSB in the CRB, where the configuration unit is N times of the first SCS, and the N is a number greater than 0. The base station may configure SSB in the CRB according to the N-times of the first SCS, and the UE may search SSB according to the N-times of the first SCS.

Alternatively, when the first SCS is 120kHz and the second SCS is 480kHz, or the first SCS is 240kHz and the second SCS is 960kHz, or the first SCS is 120kHz and the second SCS is 960kHz, the value of Kssb may be [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

First alternative: the manner of indicating the value of Kssb through the subcarrier offset (SSB-subcarrier offset) field in the SSB and the system frame number (system frame number, SFN) field in the physical broadcast channel PBCH load (payload) may specifically include:

the value of Kssb is indicated by 4 bits in a subcarrier offset field of the SSB, and the value of Kssb is [0, 15]; or the value of the Kssb is indicated by 4 bits in a subcarrier offset field of the SSB and 1 bit high-order bit in a system frame number field in a physical broadcast channel PBCH load, and the value of the Kssb is [0, 15], [0, 23] or [0, 31]; or the value of the Kssb is indicated by 4 bits in a subcarrier offset field of the SSB and 2 bits in a system frame number field in a physical broadcast channel PBCH load, and the value of the Kssb is [0, 15], [0, 23], [0, 31], [0, 47] or [0, 63]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field of the SSB and 3 bits higher order bits in the system frame number field in the physical broadcast channel PBCH payload, the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

The value of Kssb is indicated by M bits in a system frame number field in the physical broadcast channel PBCH payload, the system frame number is represented by newly adding the M bits in the system frame number field in a master information block MIB in the PBCH, and the newly added M bits are represented by bits in a control resource set-zero (control resource zero) field and/or a search space-zero (search space zero) field in a PDCCH configuration SIB1 field in the master information block MIB, that is, M bits are removed from the PDCCH configuration SIB1 field (total 8 bits) to represent the system frame number. Wherein M is 1, 2 or 3.

For example, when m=1, the system frame number field in the MIB is extended from 6 bits to 7 bits, when m=2, the system frame number field in the MIB is extended from 6 bits to 8 bits, and when m=3, the system frame number field in the MIB is extended from 6 bits to 9 bits. When the system frame number field in the MIB is extended from 6 bits to 7 bits, the data in the PBCH arrives at the coding unit in 80ms, and when the system frame number field in the MIB is extended from 6 bits to 8 bits, the data in the PBCH arrives at the coding unit in 40 ms; or when the system frame number field in the MIB is extended from 6 bits to 9 bits, the data in the PBCH arrives at the coding unit in units of 20 ms.

The second alternative: the manner of indicating the value of Kssb through the subcarrier offset (SSB-subcarrier offset) field and the PDCCH configuration system information block1 (system information block, SIB 1) (PDCCH-ConfigSIB 1) field in the SSB may specifically include:

the value of the Kssb is indicated by 4 bits in the subcarrier offset field, and the value of the Kssb is [0, 15]; or the value of the Kssb is indicated by 4 bits in the subcarrier offset field and 1 bit in the PDCCH configuration SIB1 field, and the value of the Kssb is [0, 15], [0, 23] or [0, 31]; or the value of the Kssb is indicated by 2 bits in the PDCCH configuration SIB1 field with 4 bits in the subcarrier offset field, and the value of the Kssb is [0, 15], [0, 23], [0, 31], [0, 47] or [0, 63]; or the value of the Kssb is indicated by 4 bits in the subcarrier offset field and 3 bits in the PDCCH configuration SIB1 field, and the value of the Kssb is [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

The value of Kssb may be indicated by configuring a control resource set-zero field or/and a span-zero field in the SIB1 field through the PDCCH. Comprising the following steps:

First, the value of Kssb is indicated by controlling 1-bit high-order bit or 1-bit low-order bit of the resource set-zero field, or 1-bit high-order bit or 1-bit low-order bit in the search space-zero field.

Second, the value of Kssb is indicated by a 2-bit high-order bit or a 2-bit low-order bit of the control resource set-zero field, or a 2-bit high-order bit or a 2-bit low-order bit of the search space-zero field, or a total of 2 bits in the control resource set-zero field and the search space-zero field. Wherein the total of 2 bits may consist of a 1-bit high order bit of the control resource set-zero field and a 1-bit low order bit of the search space-zero field, or may consist of a 1-bit low order bit of the control resource set-zero field and a 1-bit high order bit of the search space-zero field.

Third, the value of Kssb is indicated by a 3-bit high-order bit or a 3-bit low-order bit of the control resource set-zero field, or a 3-bit high-order bit or a 3-bit low-order bit of the search space-zero field, or a total of 3 bits in the control resource set-zero field and the search space-zero field. Wherein the total of 3 bits may consist of 2-bit high order bits of the control resource set-zero field and 1-bit low order bits of the search space-zero field, or may also consist of 2-bit low order bits of the control resource set-zero field and 1-bit high order bits of the search space-zero field.

The analysis is carried out by taking as an example the determination of the value of Kssb for the SCS combination of (SSB, CRB) at (120 kHz,480 kHz) or (240 kHz, 460 kHz), respectively. Wherein, SCS of CRB is 4 times of SCS of SSB.

For example, in the case where SCS combinations of (SSB, CRB) are (120 khz,480 khz) or (240 khz, 460 khz), respectively, SSB is configured in CRB in a unit of configuration of SCS of single SSB.

As shown in fig. 5, fig. 5 is a schematic diagram of movement of Kssb. In the case where SSB is 120kHz and CRB is 480kHz, one CRB includes 12 subcarriers, SCS of one subcarrier is 480kHz, the configuration unit (also referred to as moving unit or calculation unit) of SSB is 120kHz, moving SSB from 0kHz to 480kHz in one subcarrier in CRB needs to be performed 4 times, 48 times are required for 12 subcarriers, and the value of Kssb increases by 1 every time of moving, so that the value of Kssb is [0, 47]. In the case where SSB is 240kHz and CRB is 960kHz, one CRB includes 12 subcarriers, SCS of one subcarrier is 960kHz, the configuration unit of SSB is 240kHz, moving SSB from 0kHz to 960kHz is required 4 times in one subcarrier in CRB, 48 times are required for 12 subcarriers, and the value of Kssb is increased by 1 every time of moving, so that the value of Kssb is [0, 47].

When the SCS of CRB is 4 times that of SSB, i.e., (SSB, CRB): the manner of Kssb at (120 kHz,480 kHz) and (240 kHz,960 kHz) is shown in Table 3.

SSB	CRB	Kssb value	Using bits	Calculation unit
120kHz	480kHz	0:47	6-bits	120kHz(SSB)
240kHz	960kHz	0:47	6-bits	240kHz(SSB)

TABLE 3 Table 3

Since Kssb has a value of [0, 47], it requires 6 bits for representation. The 6 bits of the Kssb value may be indicated as follows.

(1) The value of Kssb is indicated by the system frame number (system frame number, SFN) (2-bits) in the ssb-subbearrieroffset (4-bits) +pbch payload. Further, it may be indicated by the 2-bit high order bit (most significant bit, MSB) of the SFN in the PBCH load.

At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in units of 40 ms. Since 2 bits in the system frame number field in the PBCH payload (payload) are used to represent the value of Kssb, 2 bits are newly added in the system frame number field in the master information block MIB in the PBCH to represent the system frame number, so that the system frame number field in the MIB is extended from 6 bits to 8 bits. Wherein, the newly added 2 bits can be represented by bits in a control resource set-zero (control resource zero) and/or a search space-zero (search space zero) in the SIB1 field configured by the PDCCH in the master information block MIB, that is, 2 bits are removed from the PDCCH configuration SIB1 field (total 8 bits). The method comprises the following steps:

First, any 2 bits in the "control resource zero" field or the "searchSpaceZero" field, such as 2 high order bits or 2 low order bits.

Second, the 1-bit high order bit in the "control ResourceEtzero" field + "SearchSpacezero" field.

Third, the 1-bit high order bit in the "control ResourceEtzero" field + "SearchSpacezero" field is the 1-bit low order bit.

Fourth, the 1 low order bits in the "control ResourceEtzero" field + "SearchSpacezero" field, the 1 high order bits in the "SearchSpacezero" field.

Fifth, the 1 low order bits in the "control ResourceEtzero" field + "SearchSpacezero" field and the 1 low order bits in the "SearchSpacezero" field.

(2) The value of Kssb is indicated by ssb-SubcarrierOffset (4-bits) +pdcch-ConfigSIB1 (2-bits). Wherein, the pdcch-ConfigSIB1 field may include a "control ResourceLetZero" field and a "searchSpaceZero" field. The 2 bits in the "pdcch-ConfigSIB1" field may be indicated as follows:

Second, the 1-bit high order bit in the "control resource zero" field + "searchSpaceZero" field.

Third, the 1-bit high-order bit in the "control resource zero" field + "searchSpaceZero" field;

fourth, 1 low order bit in the "control resource zero" field + "searchSpaceZero" field;

fifth, the 1-bit low-order bits in the "control resource zero" field + "searchSpaceZero" field.

For example, in the case where the SCS combinations of (SSB, CRB) are (120 kHz,480 kHz) or (240 kHz, 460 kHz), respectively, SSB is configured in the CRB in a configuration unit of SCS of SSB of 2 times.

As shown in fig. 6, fig. 6 is a schematic diagram of movement of Kssb. In the case where SSB is 120kHz and CRB is 480kHz, one CRB includes 12 subcarriers, SCS of one subcarrier is 480kHz, a configuration unit (also referred to as a moving unit or a calculating unit) of SSB is 240Hz, moving SSB from 0kHz to 480kHz in one subcarrier in CRB requires 2 times, and the 12 subcarriers require 24 times, and the value of Kssb increases by 1 every time of moving, so that the value of Kssb is [0, 23]. In the case where SSB is 240kHz and CRB is 960kHz, one CRB includes 12 subcarriers, SCS of one subcarrier is 960kHz, configuration unit of SSB is 480kHz, moving SSB from 0kHz to 960kHz is required 2 times in one subcarrier in CRB, and the value of Kssb is increased by 1 every time 12 subcarriers are moved, so that the value of Kssb is [0, 23].

When the SCS of CRB is 4 times that of SSB, i.e., (SSB, CRB): the modes of Kssb at (120 kHz,480 kHz) and (240 kHz,960 kHz) are shown in Table 4.

SSB	CRB	Range	Using bits	Calculation unit
120kHz	480kHz	0:23	5-bits	240kHz
240kHz	960kHz	0:23	5-bits	480kHz

TABLE 4 Table 4

Since Kssb has a value of [0, 23], 5 bits are required for representation. The 5 bits of the Kssb value may be indicated as follows.

(1) The value of Kssb is indicated by the system frame number (system frame number, SFN) (1-bits) in the ssb-subbearrieroffset (4-bits) +pbch payload (payload). Further, it may be indicated by the 1-bit high order bit (most significant bit, MSB) of the SFN in the PBCH load.

At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in units of 80 ms. Since 1 bit in the system frame number field in the PBCH payload (payload) is used to represent the value of Kssb, 1 bit needs to be added to the system frame number field in the master information block MIB in the PBCH to represent the system frame number, so that the system frame number field in the MIB is extended from 6 bits to 7 bits.

The newly added 1 bit may be represented by a bit in a control resource set-zero (control resource zero) or a search space-zero (search space zero) in the SIB1 field configured by the PDCCH in the master information block MIB, that is, a 1 bit representation is removed from the PDCCH configuration SIB1 field (total 8 bits). The newly added 1 bit may be any 1 bit of the "control resource zero" field and the "searchSpaceZero" field. Such as a 1-bit high order bit or a 1-bit low order bit in the "controllably resourcesetzero" field, or a 1-bit high order bit or a 1-bit low order bit in the "searchSpaceZero" field.

(2) The value of Kssb is indicated by ssb-SubcarrierOffset (4-bits) +pdcch-ConfigSIB1 (1-bits). Wherein, the pdcch-ConfigSIB1 field may include a "control ResourceLetZero" field and a "searchSpaceZero" field. Wherein, the 1 bit can be any 1 bit of the pdcch-ConfigSIB 1. Such as a 1-bit high order bit or a 1-bit low order bit in the "controllably resourcesetzero" field, or a 1-bit high order bit or a 1-bit low order bit in the "searchSpaceZero" field.

For example three, analysis was performed by taking the value of Kssb determined by SCS combination of (SSB, CRB) as (120 kHz,960 kHz). Wherein, SCS of CRB is 8 times of SCS of SSB.

In the case where the SCS combination of (SSB, CRB) is (120 kHz,960 kHz), SSB is configured in the CRB in a unit of configuration of SCS of single SSB.

As shown in fig. 7, fig. 7 is a schematic diagram of movement of Kssb. In the case where SSB is 120kHz and CRB is 960kHz, one CRB includes 12 subcarriers, SCS of one subcarrier is 960kHz, a configuration unit (also referred to as a moving unit or a calculating unit) of SSB is 120kHz, moving SSB from 0kHz to 960kHz in one subcarrier in CRB requires 8 times, 96 times for 12 subcarriers, and the value of Kssb increases by 1 every time of moving, so that the value of Kssb is [0, 95].

When the SCS of CRB is 8 times that of SSB, i.e., (SSB, CRB): the expression of Kssb at (120 kHz,960 kHz) is shown in Table 5.

SSB	CRB	Range	Using bits	Calculation unit
120kHz	960kHz	0:95	7-bits	120kHz(SSB)

TABLE 5

Since Kssb takes a value of 0, 95, 7 bits are required for representation. The 7 bits of the Kssb value may be indicated as follows.

(1) The value of Kssb is indicated by the system frame number (system frame number, SFN) (3-bits) in the ssb-subbearrieroffset (4-bits) +pbch payload. Further, it may be indicated by the 3-bit high order bit (most significant bit, MSB) of the SFN in the PBCH load.

At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in units of 20 ms. Since 3 bits in the system frame number field in the PBCH payload (payload) are used to represent the value of Kssb, 3 bits are newly added in the system frame number field in the master information block MIB in the PBCH to represent the system frame number, so that the system frame number field in the MIB is extended from 6 bits to 9 bits. Wherein, the newly added 3 bits can be represented by bits in a control resource set-zero (control resource zero) and/or a search space-zero (searchSpaceZero) in the SIB1 field configured by the PDCCH in the master information block MIB, that is, 3 bits are removed from the PDCCH configured SIB1 field (total 8 bits). The method comprises the following steps:

First, any 3 bits in the "control resource zero" field or the "searchSpaceZero" field, such as 3 high order bits or 3 low order bits.

Second, any 2 bits in the "control resource zero" field and any 1 bit in the "searchSpaceZero" field.

Third, any 1 bit in the "control resource zero" field and any 2 bits in the "searchSpaceZero" field.

(2) The value of Kssb is indicated by ssb-SubcarrierOffset (4-bits) +pdcch-ConfigSIB1 (3-bits). Wherein, the pdcch-ConfigSIB1 field may include a "control ResourceLetZero" field and a "searchSpaceZero" field. The 3 bits in the "pdcch-ConfigSIB1" field may be indicated as follows:

first, by any 3 bits in the "control ResourceLeetzero" field in the "pdcch-ConfigSIB1" field, such as 3 high order bits or 3 low order bits in the "control ResourceLeetzero" field.

Second, by any 3 bits in the "searchSpaceZero" field in the "pdcch-ConfigSIB1" field, for example, 3 high order bits or 3 low order bits in the "searchSpaceZero" field.

Third, using a total of 3-bit representation of the combination of the field "control resource zero" and the field "searchSpaceZero" in the field "pdcch-ConfigSIB1", comprising:

1. 2 high order bits in the "control resource zero" field + "searchSpaceZero" 1 high order bits in the "searchspaczero" field;

2. 2 high order bits in the "control resource zero" field + "searchSpaceZero" 1 low order bits in the "searchspaczero" field;

3. a 1-bit high-order bit in the "control resource zero" field + "searchSpaceZero" field, and a 2-bit high-order bit in the "searchspaczero" field;

4. the 1-bit high-order bit in the "control resource zero" field + "searchSpaceZero" field, the 2-bit low-order bit in the "searchspaczero" field;

5. the 1-bit low-order bit in the "control resource zero" field + "searchSpaceZero" field, and the 2-bit high-order bit in the "searchspaczero" field;

6. a 1-bit low-order bit in the "control resource zero" field + "searchSpaceZero" field, and a 2-bit low-order bit in the "searchspaczero" field;

7. 2 low order bits in the "control resource zero" field + "searchSpaceZero" 1 high order bits in the "searchspaczero" field;

8. the 2-bit low-order bits in the "control resource zero" field + the 1-bit low-order bits in the "searchspaczero" field.

For example, in the case where the SCS combination of (SSB, CRB) is (120 kHz,960 kHz), SSB is configured in the CRB in a configuration unit of SCS of SSB of 2 times or 4 times.

As shown in fig. 8, fig. 8 is a schematic diagram of movement of Kssb. In the case where the SSB is 120kHz and the CRB is 960kHz, one CRB includes 12 subcarriers and SCS of one subcarrier is 960kHz. In the case where the configuration unit of SSB is 240Hz, the SSB needs to be shifted 4 times from 0kHz to 960kHz in one subcarrier in CRB, and 48 times for 12 subcarriers, and the value of Kssb increases by 1 every shift, so that the value of Kssb is [0, 47]. In the case where the configuration unit of SSB is 480Hz, the SSB needs to be shifted 2 times from 0kHz to 960kHz in one subcarrier in CRB, and the number of 12 subcarriers needs to be 24 times, and the value of Kssb increases by 1 every shift, so that the value of Kssb is [0, 23]. It can be seen that when the SSB is placed in units of 480kHz, the SSB is more sparse in the frequency domain than when the SSB is placed in units of 240 kHz.

When the SCS of CRB is 8 times that of SSB, i.e., (SSB, CRB): the manner of Kssb at (120 kHz,960 kHz) is shown in Table 6.

SSB	CRB	Range	Using bits	Calculation unit
120kHz	960kHz	0:47	6-bits	240kHz
120kHz	960kHz	0:23	5-bits	480kHz

TABLE 6

In the case where the SCS combination of (SSB, CRB) is (120 kHz,960 kHz), when the SSB is placed at the CRB in the configuration unit of 240kHz, the value of Kssb is [0, 47], that is, it is expressed with 6 bits. The 6 bits of the Kssb value may be indicated as follows:

At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in units of 40 ms. Since 2 bits in the system frame number field in the PBCH payload (payload) are used to represent the value of Kssb, 2 bits are newly added in the system frame number field in the master information block MIB in the PBCH to represent the system frame number, so that the system frame number field in the MIB is extended from 6 bits to 8 bits. Wherein, the newly added 2 bits can be represented by bits in a control resource set-zero (control resource zero) and/or a search space-zero (search space zero) in the SIB1 field configured by the PDCCH in the master information block MIB, that is, 2 bits are removed from the PDCCH configuration SIB1 field (total 8 bits). The newly added 2 bits may include the following indication:

In the case where the SCS combination of (SSB, CRB) is (120 kHz,960 kHz), when the SSB is placed at the CRB in the configuration unit of 480kHz, the value of Kssb is [0, 23], that is, expressed with 5 bits. The 5 bits of the Kssb value may be indicated as follows:

It should be noted that, in the case where the SSB is configured in the CRB by taking the first SCS with other multiple as the configuration unit, the foregoing is similar to the above case, and the description of the present application is omitted.

Alternatively, the SSB may be configured within the CRB in a frequency division multiplexed manner. I.e. one CRB includes a plurality of SSBs therein. Further, the SSBs include a first SSB and a second SSB, the first SSB is a first SSB in the CRB, the second SSB is located in a higher frequency domain position in the CRB relative to the first SSB, and Kssb corresponding to the first SSB is k _{ssb_1} Kssb corresponding to the second SSB is k _{ssb_m} The k is _{ssb_1} And said k _{ssb_m} The method meets the following conditions:

wherein u1 is the second carrier interval, u2 is the first subcarrier interval, and N is the number of parts of the CRB that are equally divided in the frequency domain.

For example, in the case where the SCS combinations of (SSB, CRB) are (120 kHz,480 kHz) or (240 kHz, 460 kHz), respectively, SSB is arranged in the CRB at 120 kHz. The SCS of CRB is 4 times that of SSB, one CRB includes 12 subcarriers, and Kssb has a value of 0, 47 without using frequency division multiplexing, and is expressed by 6 bits. In the case of frequency division multiplexing, the CRB is divided into N equal parts, each SSB is located in the CRB range of every 1/N, and the relationship between the offset Kssb and the number of bits used and N between each SSB and the CRB subcarrier #0 is shown in table 7 below.

N equal parts (N)	Number of bits
2	5
3	4

TABLE 7

When 5 bits are used to represent the value of Kssb, this is represented by one of the following two ways:

(a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

(b) ssb-SubcarrierOffset field (4-bits) +pdcch-ConfigSIB1 field (1-bits).

Wherein k of SSB coexisting with FDM mode of higher frequency domain position _{ssb_m} The calculation mode of (a) is as follows:

where "12" indicates that one CRB contains 12 subcarriers, u1 indicates the subcarrier spacing of the CRB, and u2 indicates the subcarrier spacing of the SSB.Representing one SCS used by CRB for SSB in frequency domainMultiple, k _{ssb_1} Is SSB in a lower frequency domain position.

For k _{ssb_1} And k _{ssb_m} One implementation is:

k configured by base station to UE _{ssb_1} And k _{ssb_m} Is the same as the bits of the (k) calculated by the UE _{ssb_1} And k _{ssb_m} The values are the same. The offset between SSB and CRB subcarrier #0 for the higher frequency domain position is calculated by the formulaAnd (5) calculating.

For example, as shown in FIG. 9, in the case where SCS of (SSB, CRB) is (120 kHz,480 kHz), SSB is placed in units of 120kHz,n=2, two SSBs of 120kHz are located in the upper half and lower half of the CRB of 480kHz, respectively. SSB#1 is located between subcarriers #0 to #5 in one CRB, and SSB#2 is located between subcarriers #6 to #11 in one CRB. When the bit of the base station configuration is "00111", k _{ssb_1} And k _{ssb_2} The values of (2) are 7, i.e., the lowest frequency domain position of SSB#1 is offset from subcarrier #0 in the CRB by 7 120kHz subcarriers, and the lowest frequency domain position of SSB#2 is offset from subcarrier #0 in the CRB by 31 (24+7) 120kHz subcarriers.

The above method is also applicable to the case where SCS combinations of (SSB, CRB) are (240 kHz,960 kHz), and will not be described here again.

In the case of configuring SSBs in a frequency division multiplexing manner, at least 1 SSB among SSBs of the plurality of FDMs is a cell-defined SSB (CD-SSB), and other SSBs may be NCD-SSB or CD-SSB.

When the offset between SSB and CRB subcarrier #0 of FDM satisfies the following two conditions:

(1)

(2) K of base station configuration _{ssb_1} And k _{ssb_m} The values of (2) are the same.

When the SSB first detected by the UE is NCD-SSB, the UE may determine that the SSB is the NCD-SSB based on Kssb (the Kssb may be k corresponding to the first SSB _{ssb_1} Or k corresponding to the last SSB _{ssb_m} ) And the frequency domain position of the other SSB is reversely deduced. Comprising the following steps:or alternativelyFor example, as shown in fig. 8, when m=2, u1=480 khz, u2=120 khz, n=2, the value of Kssb detected by the ue is "7" (the corresponding bit is "00111"), SSB can be searched for at the following two frequency domain positions:

(1) Assuming that the UE detects ssb#1, the frequency domain location of ssb#2 is:

(2) Assuming that the UE detects ssb#2, the frequency domain location of ssb#1 is

For example, in the case where SCS combinations of (SSB, CRB) are (120 kHz,960 kHz), SSB is arranged in the CRB at 120 kHz. The SCS of CRB is 8 times that of SSB, one CRB includes 12 subcarriers, and Kssb has a value of 0, 95 without using frequency division multiplexing, and is represented by 7 bits. In the case of frequency division multiplexing, the CRB is divided into N equal parts, each SSB is located in the CRB range of every 1/N, and the relationship between the offset Kssb and the number of bits used and N between each SSB and the CRB subcarrier #0 is shown in table 8 below.

N equal parts (N)	Number of bits

TABLE 8

First, when a value of Kssb is indicated by using 6 bits, only 2 SSBs can be placed in one CRB of 960kHz, each SSB being located in subcarriers #0 to #5 and subcarriers #6 to #11 of the CRB of 960kHz, and the corresponding subcarrier numbers of 120kHz being subcarriers #0 to #47 and subcarriers #48 to #95, respectively.

The 6 bits are represented by one of two ways:

(a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (2-bits).

(b) ssb-SubcarrierOffset field (4-bits) +pdcch-ConfigSIB1 field (2-bits).

Wherein, the SSB (such as SSB#2) with the FDM mode of the higher frequency domain position coexists, the spacing between the SSB and the subcarrier #0 in the current CRB is k _{ssb_2} The specific calculation mode of (a) is as follows:k _{ssb_1} representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

Second, when a value of Kssb is indicated using 5 bits, the 5 bits are represented by one of two ways:

(a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

(b) ssb-SubcarrierOffset field (4-bits) +pdcch-ConfigSIB1 field (1-bits).

Within a 960kHz CRB, 3 or 4 SSBs may be placed, including:

(1) When one CRB supports SSB coexistence of 3 FDMs, each SSB is located at subcarrier # 0-subcarrier #3, subcarrier # 4-subcarrier #7, and subcarrier # 8-subcarrier #11 of the CRB of 960kHz, and the corresponding subcarrier numbers of 120kHz are subcarrier # 0-subcarrier #31, subcarrier # 32-subcarrier #63, and subcarrier # 64-subcarrier #95, respectively. The specific calculation method of the interval Kssb between the SSB and the subcarrier #0 of the CRB is as follows:n=3, m=2 or 3.k (k) _{ssb_1} Representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

(2) When a CRB supportsWhen 4 SSBs of FDM coexist, each SSB is respectively positioned at subcarriers # 0-subcarriers #2, # 3-subcarriers #5, # 6-subcarriers #8 and # 9- #11 of CRBs of 960kHz, and the corresponding subcarrier numbers of 120kHz are respectively subcarriers # 0-subcarriers #23, # 24-subcarriers #47, # 48-subcarriers #71 and # 72-subcarriers #95. The specific calculation method of the interval Kssb between the SSB and the subcarrier #0 of the CRB is as follows: N=4, m=2, 3 or 4.k (k) _{ssb_1} Representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

Third, when a value of Kssb is indicated using 4 bits, it is indicated by a ssb-subbearrieroffset field (4-bits).

Within one 960kHz CRB, 6 SSBs may be placed. When one CRB supports SSB coexistence of 6 FDMs, each SSB is located in subcarriers #0 to #1, subcarriers #2 to #3, subcarriers #4 to #5, subcarriers #6 to #7, subcarriers #8 to #9, and subcarriers #10 to #11 of the CRB of 960kHz, and the corresponding 120kHz subcarriers are numbered as subcarriers #0 to #15, subcarriers #16 to #31, subcarriers #32 to #47, subcarriers #48 to #63, subcarriers #64 to #79, and subcarriers #80 to #95, respectively. The specific calculation method of the interval Kssb between the SSB and the subcarrier #0 of the CRB is as follows:n=6, m=1, 2, 3, 4 or 5.k (k) _{ssb_1} Representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

For k _{ssb_1} And k _{ssb_m} One implementation is: k (k) _{ssb_1} And k _{ssb_m} The values of (a) are the same, i.e. the base station is configured for the terminal to instruct the terminal to calculate k _{ssb_1} And k _{ssb_m} Is the same.

For the case of FDM placed SSBs, at least 1 SSB of the plurality of FDM SSBs is a CD-SSB, and the remaining SSBs are NCD-SSB or CD-SSB.

The offset between the different SSBs and CRB subcarrier #0 satisfies the following two conditions:

(1) (2) K of base station configuration _{ssb_1} And k _{ssb_m} The values of (2) are the same.

When the SSB first detected by the UE is NCD-SSB, the UE may determine that the SSB is the NCD-SSB based on Kssb (the Kssb may be k corresponding to the first SSB _{ssb_1} Or k corresponding to the last SSB _{ssb_m} ) And the frequency domain position of the other SSB is reversely deduced. Comprising the following steps:or alternatively

For example, in the case where SCS combinations of (SSB, CRB) are (120 kHz,960 kHz), respectively, SSB is arranged in the CRB at 240 kHz. One CRB includes 12 subcarriers, and Kssb has a value of 0, 47 in the case where frequency division multiplexing is not used, and is expressed by 6 bits. In the case of frequency division multiplexing, the CRB is divided into N equal parts, each SSB is located in the CRB range of every 1/N, and the value of the offset Kssb between each SSB and the CRB subcarrier #0 and the relationship between the number of bits used and N are shown in table 9.

N equal parts (N)	Number of bits

2	5

TABLE 9

When a 4-bit indication is used to indicate the value of Kssb, this is indicated by the ssb-subbearrieroffset field (4-bits). In one 960kHz CRB, only 3 SSBs can be placed, each SSB is respectively positioned in subcarriers #0 to #3, subcarriers #4 to #7 and subcarriers #8 to #11 of the 960kHz CRB, and the corresponding subcarrier numbers of 120kHz are subcarriers #0 to #15, subcarriers #16 to #31 and subcarriers #32 to #47.

The specific calculation method of the interval Kssb between the higher frequency SSB and the subcarrier #0 of the CRB is as follows:n=6, m=2 or 3.k (k) _{ssb_1} Representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

When a value of Kssb is indicated using 5 bits, the 5 bits are represented by one of two ways:

(a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

(b) ssb-SubcarrierOffset field (4-bits) +pdcch-ConfigSIB1 field (1-bits).

In one 960kHz CRB, only 2 SSBs can be placed, each SSB is respectively positioned in subcarriers #0 to #5 and subcarriers #6 to #11 of the 960kHz CRB, and the corresponding subcarrier numbers of 120kHz are respectively subcarrier #0 to subcarrier #47 and subcarrier #48 to subcarrier #95.

Wherein,the Kssb of the interval between the SSB of the higher frequency and the subcarrier #0 of the CRB is specifically calculated as follows:N＝2，m＝2。k _{ssb_1} representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

For k _{ssb_1} And k _{ssb_m} One implementation is:

k _{ssb_1} and k _{ssb_m} The values of (a) are the same, i.e. the base station is configured for the terminal to instruct the terminal to calculate k _{ssb_1} And k _{ssb_m} Is the same.

For example four, for the case where the SCS combinations of (SSB, CRB) are (120 kHz,960 kHz), respectively,SSBs are configured within CRBs at 480 kHz. Each SSB is atMoving within the range, n=2, i.e. the CRB is equally divided into N equal parts. The specific calculation method of the interval Kssb between the SSB and the subcarrier #0 of the CRB is as follows:N＝2，m＝2。k _{ssb_1} representing the spacing between the SSB and the subcarrier #0 of the CRB in the lower frequency band.

For k _{ssb_1} And k _{ssb_m} One implementation is: k (k) _{ssb_1} And k _{ssb_m} The values of (a) are the same, i.e. the base station configures the UE with a value indicating k _{ssb_1} And k _{ssb_m} Is the same.

For the case of FDM placed SSBs, at least 1 SSB of the plurality of FDM SSBs is a CD-SSB, and the remaining SSBs are NCD-SSB or CD-SSB. The offset between the different SSBs and CRB subcarrier #0 satisfies the following two conditions:

(1)

In a third alternative, the value of Kssb is indicated by 1 bit or 2 bits in a subcarrier offset (SSB-subcarrier offset) field in the SSB, where 1 bit in the subcarrier offset (SSB-subcarrier offset) field is a 1-higher order bit or a 1-lower order bit in the subcarrier offset field. Or the 2 bits in the subcarrier offset field are 2-bit high-order bits or 2-bit low-order bits in the subcarrier offset field.

Alternatively, when the first SCS is 480kHz and the second SCS is 120kHz, or the first SCS is 960kHz and the second SCS is 240kHz, or the first SCS is 960kHz and the second SCS is 120kHz, the Kssb takes on a value of [0,1] or [0,2].

Wherein the remaining bits in the subcarrier offset field of the SSB are used to represent a Q value, where the Q value is used to indicate SSBs with the same index at multiple candidate SSB locations; or the remaining bits in the subcarrier offset field of the SSB are used to distinguish the master information block MIB of the licensed band from the MIB of the unlicensed band; or the remaining bits in the subcarrier offset field of the SSB are used to indicate an interval between a plurality of PDCCHs carrying a set of control resources in quasi co-sited relation with the SSB, or to indicate to a terminal device to listen to the PDCCHs on one or more listening occasions. Optionally, the Q value is 1, 2, 4, 8, 16, 32, or 64.

For example, in the case where the SCS combination of (SSB, CRB) is (480 kHz,120 kHz), the SCS of the subcarrier of one CRB is 120kHz, the arrangement unit of SSB is 480Hz, and the SSB is moved 3 times from the 1 st subcarrier to the 12 th subcarrier in the CRB, and the value of Kssb is increased by 1 every time of the movement, so that the value of Kssb is [0,2]. Alternatively, in the case where the SCS combination of (SSB, CRB) is (960 khz,240 khz), the SCS of the subcarriers of one CRB is 240khz, the arrangement unit of SSB is 960Hz, and the SSB is moved 3 times from the 1 st subcarrier to the 12 th subcarrier in the CRB, and the value of Kssb is increased by 1 every time of the movement, so that the value of Kssb is [0,2]. Or alternatively. When the SSB is 960kHz and the CRB is 120kHz, the SCS of the subcarrier of one CRB is 120kHz, the configuration unit of the SSB is 960kHz, and the SSB needs to be moved 2 times from the 1 st subcarrier to the 12 th subcarrier in the CRB, and the value of Kssb increases by 1 every time of the movement, so that the value of Kssb is [0,1]. For the above three cases, the manner of expression of Kssb is shown in table 10.

SSB	CRB	Value taking	Using bits	Calculation unit
480kHz	120kHz	0:2	2-bits	480kHz(SSB)
960kHz	240kHz	0:2	2-bits	960kHz(SSB)
960kHz	120kHz	0:1	1-bits	960kHz(SSB)

Table 10

As shown in Table 10, in the case where SCS combinations of (SSB, CRB) are (480 kHz,120 kHz), SSB is placed in 480kHz units. In the case where the SCS combination of (SSB, CRB) is (960 kHz,240 kHz), the SSB is placed in 960kHz units. Thus, kssb takes a value of 0 to 2, using 2 bits, represented by any 2 bits in the "ssb-subsearrieroffset" field, such as 2 higher order bits or 2 lower order bits.

Wherein 2 bits in the "ssb-subbrierOffset" field are used to indicate the value of Kssb, and the remaining 2 bits in the "ssb-subbrierOffset" field may be used to indicate other information, including:

(1) The Q value is indicated using at least 1 bit, where the Q value is extended from (1, 2,4, 8) to (1, 2,4,8, 16, 32, 64) before.

(2) The MIB of the licensed band is distinguished from the MIB of the unlicensed band. The content of the MIB in the licensed band is different from that of the MIB in the unlicensed band. On the unlicensed band, the "subclrierspacengcommon" field and the "LSB of ssb-subclrieroffset" field in MIB jointly represent the Q value.

(3) An offset between multiple PDCCHs carrying coreset#0 indicating that a QCL relationship exists with a current SSB or a UE is instructed to monitor PDCCHs carrying coreset#0 on multiple listening positions where a QCL relationship exists with a certain SSB.

As shown in table 10, when the SCS combination of (SSB, CRB) is (120 kHz,960 kHz), SSB is placed in 960kHz, and hence Kssb has a value of 0 to 1, and 1 bit is used, and any 1 bit in the "SSB-subsearrier offset" field is used, for example, 1 higher order bit or 1 lower order bit.

Wherein 1 bit in the "ssb-subbrierOffset" field is used to indicate the value of Kssb, and the remaining 3 bits in the "ssb-subbrierOffset" field may be used to indicate other information, including:

(1) Using at least 1 bit to indicate the Q value, wherein the value of Q extends from (1, 2,4, 8) to (1, 2,4,8, 16, 32, 64);

(2) The MIB of the licensed band is distinguished from the MIB of the unlicensed band.

In the embodiment of the application, when a new SCS is introduced, under the SCS combination modes of different SSB and CRB, the value of Kssb is indicated by a subcarrier offset field in the SSB and a system frame number field in a Physical Broadcast Channel (PBCH) load, or the value of Kssb is indicated by a subcarrier offset field in the SSB and a PDCCH configuration system information block 1 field, or the value of Kssb is indicated by 1 bit or 2 bits in the subcarrier offset field in the SSB, and the rest bits are used for indicating other information. Thereby improving the accuracy of the terminal equipment to detect SSB.
