Description

Technical Field

[0001] This application relates to the field of network technology, and in particular to a method and apparatus for determining resource location. Background Technology

[0002] With technological advancements, the available frequency bands have continuously increased. New Radio (NR) access technology divides frequency bands into two main parts: Frequency Range 1 (FR1) and FR2. FR2 primarily refers to the 450MHz–6GHz bandwidth, while FR2 primarily refers to the 24.25GHz–52.6GHz bandwidth. In addition, the 52.6GHz–70GHz band (above 52.6GHz) is also included in the usage scope of the next 5G mobile communication system. The sub-carrier spacing (SCS) or its numerical value differs across frequency bands, resulting in different frame structure lengths. These different numerical settings enable NR to simultaneously support multiple services. Currently, the FR1 band supports SCS of 15kHz and 30kHz, while the FR2 band supports SCS of 60kHz, 120kHz, and 240kHz. For the above 52.6GHz band, according to the results of the latest RAN1_103 meeting, in addition to the mandatory support for 120kHz SCS, at least two SCSs will be supported among {240kHz, 480kHz, 960kHz}, but the total number of supported SCSs will not exceed three.

[0003] Because the introduction of the new SCS changes 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 under different SCS combination methods of synchronization signal block (SSB) and common resource block (CRB), the user equipment (UE) cannot accurately detect the SSB. Summary of the Invention

[0004] This application provides a method and apparatus for determining resource locations, which can improve the accuracy of SSB detection.

[0005] In a first aspect, embodiments of this application provide a resource location determination method, which can be applied to terminal devices or network devices, or components within terminal devices or network devices, such as chips, processors, etc. The method includes: obtaining the first subcarrier spacing (SCS) of a Synchronization Signal Block (SSB) and the second subcarrier spacing (SCS) of a Common Resource Block (CRB); and determining, based on the first and second SCSs, the offset Kssb of the lowest frequency domain position of the SSB relative to the starting position of the first subcarrier in the CRB. The value of Kssb is used to determine the resource location of the SSB. The value of Kssb is indicated by the subcarrier offset field in the SSB and the system frame number field in the Physical Broadcast Channel (PBCH) payload, or by the subcarrier offset field in the SSB and the Configuration System Information Block (SIB1) field in the Physical Downlink Control Channel (PDCCH), or by 1 bit or 2 bits in the subcarrier offset field of the SSB. By introducing a new SCS, under different SSB and CRB SCS combinations, the value of Kssb is indicated by the above indication methods, improving the accuracy of the terminal device in detecting the SSB.

[0006] In one possible design, the value of Kssb is determined based on the configuration unit of the SSB in the CRB, where the configuration unit is N times the first SCS, and N is a number greater than 0. The value of Kssb varies depending on the configuration unit of the SSB.

[0007] In another possible design, the SSB is configured as N times the first SCS, or the SSB is searched as N times the first SCS.

The two high-order bits in the system frame number field of the BCH payload indicate that the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47] or [0, 63]; or the value of Kssb is the same as the value of the 4 bits in the subcarrier offset field of the SSB and the three high-order bits in the system frame number field of the physical broadcast channel PBCH payload, indicating that the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

[0013] In another possible design, the value of Kssb is indicated by M bits in the system frame number field of the physical broadcast channel PBCH payload. M bits are added to the system frame number field of the main information block MIB in the PBCH. The added M bits are represented by bits in the control resource set - zero field and / or search space - zero field of the PDCCH configuration SIB1 field in the main information block MIB. M is 1, 2 or 3.

[0014] In another possible design, 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 units of 40ms; 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 20ms.

[0015] In another possible design, the value of Kssb is indicated by 4 bits in the subcarrier offset field, with a value of [0, 15]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field and 1 bit in the PDCCH configuration SIB1 field, with a value of [0, 15], [0, 23], or [0, 31]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field and 2 bits in the PDCCH configuration SIB1 field, with a value of [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 and 3 bits in the PDCCH configuration SIB1 field, with a value of [0, 15], [0, 23], [0, 31], [0, 47], [0, 63], or [0, 97].

[0017] In another possible design, multiple SSBs are configured within the CRB using frequency division multiplexing. These multiple SSBs include a first SSB and a second SSB. The first SSB is the first SSB within the CRB, and the second SSB is located at a higher frequency position within the CRB relative to the first SSB. The Kssb corresponding to the first SSB is k. ssb_1 The Kssb corresponding to the second SSB is k. ssb_m k ssb_1 and k ssb_m satisfy:

[0018]

[0019] Where u1 is the second carrier spacing, u2 is the first subcarrier spacing, and N is the number of equal parts into which the frequency domain of the CRB is divided. When configuring the SSB using frequency division multiplexing, determining the value of Kssb not only improves resource utilization but also enhances the accuracy of SSB detection.

[0020] In another possible design, 1 bit in the subcarrier offset field is either 1 high-order bit or 1 low-order bit in the subcarrier offset field; or 2 bits in the subcarrier offset field are either 2 high-order bits or 2 low-order bits in the subcarrier offset field.

[0021] In another possible design, the remaining bits in the subcarrier offset field of the SSB are used to represent the Q value, which indicates 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 between the Master Information Block (MIB) of licensed frequency bands and the MIB of unlicensed frequency bands; or the remaining bits in the subcarrier offset field of the SSB are used to indicate the interval between multiple PDCCHs carrying control resource sets that have a quasi-co-location relationship with the SSB, or to indicate that the terminal device listens to the PDCCH at one or more listening times. Using the remaining bits in the subcarrier offset field to indicate other information improves resource utilization.

[0022] In another possible design, the Q value is 1, 2, 4, 8, 16, 32, or 64.

[0044] The embodiments of this application are described below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, Figure 1This is a schematic diagram of the architecture of a communication system 100 provided in an embodiment of this application.

Furthermore, terminal devices 104 to 106 can also form a communication system. In this communication system, terminal device 105 can send downlink data to terminal device 104 or terminal device 106. The method described in this embodiment can be applied to... Figure 1 In the communication system 100 shown.

[0046] This application is mainly applied to mobile communication systems operating in shared frequency bands, primarily targeting the above 52.6GHz frequency band, such as the 60GHz shared frequency band.

[0047] The above 52.6 GHz frequency band includes both licensed and unlicensed bands. Unlicensed bands are also known as shared bands. Within the framework of 5G mobile communication technology, technologies deployed in shared bands are collectively referred to as new radio unlicensed (NRU) technology. Besides NR systems, shared bands also include other systems such as radar, wireless-fidelity (Wi-Fi), Bluetooth, and other inter-carrier access systems. Therefore, systems operating in shared bands are required to support all or some of the following key technologies: Listen Before Talk (LBT), Transmit Power Control (TPC), and Dynamic Frequency Selection (DFS). The LBT mechanism requires all access devices to obtain information about interference in the target channel's frequency band before using it. Only when the interference level on the target channel does not exceed a preset threshold can the target channel be used. The TPC mechanism refers to the restriction that transmitting devices operating on shared licenses cannot increase their transmit power indefinitely in order to avoid affecting the normal communication of other access devices. The DFS mechanism refers to the requirement that systems operating on shared licenses should promptly avoid the frequency bands occupied by high-priority systems and dynamically switch to frequency bands with lower interference.

[0048] However, for receiving devices accessing different frequency bands, such as user equipment (UE), they will first detect the synchronization signal block pattern (SS / PBCH Block Pattern / SSB) sent by the base station (gNB, gNodeB). Figure 2 As shown, Figure 2This is a schematic diagram of an SSB. An SSB can consist of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). It comprises a two-dimensional region of four orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 20 resource blocks (RBs) in the frequency domain. The UE can achieve cell synchronization and coarse symbol-level timing synchronization by demodulating the PSS and SSS. The PBCH carries master information block (MIB) information from higher layers. By demodulating the MIB information, system frame-level timed synchronization can be completed, and relevant configuration information of system information block 1 / remaining minimum system information (SIB1 / RMSI) can be obtained. That is, the type 0 of SIB1 / RMSI, physical downlink control channel (Type0-PDCCH) and physical downlink shared channel (PDSCH), are demodulated through the field (pdcch-ConfigSIB1). Control resource set (CORESET) #0 is located in Type0-PDCCH.

[0049] The MIB is carried in the PBCH channel within the SSB. The MIB may include the following fields: "systemFrameNumber" field, representing the lower 6 bits of the system frame; "subCarrierSpacingCommon" field, representing the subcarriers of SIB1, message (Msg) 2 / 4, and other system information (OSI); "ssb-SubcarrierOffset" field, representing the offset between the SSB and subcarrier #0 in the common resource block (CRB); "dmrs-TypeA-Position" field, representing the position of the first demodulation reference signal (DMRS); "pdcch-ConfigSIB1" field, representing the parameter configuration of CORESET, search space, and related PDCCH; "cellBarred" field, indicating whether the UE is allowed to access the cell; "intraFreqReselection" field, representing the UE's cell selection or reselection within the intra-frequency measurement; and "spare" field, which are temporarily unused legacy bits.

[0050] For systems operating in licensed and shared frequency bands, the same fields in the MIB represent different contents. Specifically, for systems operating in shared frequency bands, considering the LBT mechanism, the base station cannot transmit a specific SSB at a specified location. Therefore, a new Q value is defined, namely... It is represented by 2 bits, taking four values ​​{1, 2, 4, 8}. The UE can calculate and obtain multiple candidate locations that transmit the same SSB index by demodulating the Q value and according to the DMRS sequence. The multiple candidate locations are understood by the UE as having the same quasi co-location (QCL) relationship, such as corresponding to the same downlink beam direction.

[0051] Upon initial access to the cell, the UE, after acquiring the target frequency, searches for a Synchronization Boundary Signal (SSB) in the frequency domain, using a sync raster as the unit. After finding a suitable SSB in the frequency domain, the UE calculates and obtains the Kssb by demodulating the SSB. Here, Kssb represents the interval between the lowest frequency domain position of the SSB in the RB overlapping with the CRB and the subcarrier index #0 in that CRB.

[0052] like Figure 3 As shown, Figure 3This is a schematic diagram of the distance between the SSB and CRB. Fields “absoluteFrequencyPointA” (3), “offsetToPointA” (1), and “absoluteFrequencySSB” (2) are all stored in SIB1. Field “absoluteFrequencyPointA” (3) represents the absolute frequency domain position of the reference RB (CRB#0), field “absoluteFrequencySSB” (2) represents the absolute frequency domain position of the SSB, and field “offsetToPointA” (1) represents the frequency domain offset between the data channel and point A, where point A is the position of subcarrier #0 on CRB#0.

[0053] For systems operating on FR1, Kssb values ​​range from 0 to 31, determined by a 4-bit "ssb-SubcarrierOffset" field plus a 1-bit (PBCH payload). The Kssb value is indicated by a total of 5 bits. For systems operating at FR2, the Kssb value ranges from 0 to 15, indicated by the "ssb-SubcarrierOffset" field, which is represented by a total of 4 bits. The Kssb value is related to the SCS between the SSB and CRB. The Kssb values ​​for different frequency bands are shown in Table 1.

[0054]

[0055] Table 1

[0056] It should be noted that for the UE, the default demodulated SSB is the cell-define SSB (CD-SSB). The CD-SSB contains the necessary information for the UE's initial access, such as configuration information indicating the transmission of SIB1 / remaining minimum system information (RMSI). In contrast to the CD-SSB is the Non-CD SSB, which is primarily used for radio resource management (RRM). The PBCH in a Non-CDSSB does not directly indicate the RMSI PDCCH search space; that is, the UE cannot camp or access the target cell through this type of SSB. This application primarily focuses on determining the location of the CD-SSB.

[0057] As 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 relatively large, ranging from 0 to 23. However, when the SCS of the SSB and the SCS of the CRB are (30kHz, 15kHz), the value of Kssb ranges only from 0 to 5. For the FR2 system, because the SCS of the SSB is greater than the SCS of the CRB, the value of Kssb has the largest range, ranging from 0 to 11, i.e., when the SCS of the SSB and the SCS of the CRB satisfy (120kHz, 120kHz). For systems operating in the shared frequency band (NRU system), the low-order bit (LSB of ssb-SubcarrierOffset) and the "SubCarrierSpacingComm" field in the "ssb-SubcarrierOffset" field are used to indicate the Q value. Therefore, the placement of the SSB or the formula for calculating Kssb is: As shown in Table 2 With K SSB The relationship.

[0058]

[0059] Table 2

[0060] in, The value range of K is 0-23. SSB The value of is an even number between 0 and 22.

[0061] Release 17 is standardizing the above 52.6 GHz band, and determining the SCS (Super Subcarrier Classification) for the SSB (Secondary Subcarrier) and CRB (Crown Subcarrier) has become one of the main points of discussion. Besides the mandatory 120 kHz SCS, two subcarriers will be selected from {240 kHz, 480 kHz, 960 kHz} as optional subcarriers. Because the introduction of the new SCS changes the offset Kssb (the position of the lowest frequency domain of the SSB relative to the starting position of the first subcarrier in the CRB) under different SSB and CRB SCS combinations, the UE may be unable to accurately detect the SSB. To solve the above technical problem, this application provides the following solution.

[0062] like Figure 4 As shown, Figure 4 This is a flowchart illustrating a method for determining resource location provided in an embodiment of this application. The steps in this embodiment include at least:

[0063] S401, obtain the first subcarrier spacing SCS of the synchronization signal block SSB and the second subcarrier spacing SCS of the common resource block CRB.

[0064] The first subcarrier spacing (SCS) can be 120kHz, 240kHz, 480kHz, or 960kHz. The second subcarrier spacing (SCS) can also be 120kHz, 240kHz, 480kHz, or 960kHz. Different combinations of SCS for the SSB and CRB can include: the first SCS being 120kHz and the second SCS being 480kHz; the first SCS being 240kHz and the second SCS being 960kHz; or the first SCS being 120kHz and the second SCS being 960kHz. Alternatively, the first SCS being 480kHz and the second SCS being 120kHz; or the first SCS being 960kHz and the second SCS being 240kHz; or the first SCS being 960kHz and the second SCS being 120kHz. However, these combinations are not limited to the above.

[0065] It should be noted that for the above 52.6GHz band, in addition to supporting 120kHz SCS, SSB and CRB can also support at least two of the following SCS: 240kHz, 480kHz and 960kHz.

[0066] S402, based on the first SCS and the second SCS, determine the value of the offset Kssb of the lowest frequency domain position of the SSB relative to the starting position of the first subcarrier (subcarrier #0) in the CRB. The value of Kssb is used to determine the resource position of the SSB. The value of Kssb is indicated by the subcarrier offset (ssb-SubcarrierOffset) field in the SSB and the system frame number (SFN) field in the physical broadcast channel PBCH payload, or by the subcarrier offset (ssb-SubcarrierOffset) field in the SSB and the system information block 1 (SIB1) (pdcch-ConfigSIB1) field in the PDCCH, or by 1 bit or 2 bits in the subcarrier offset (ssb-SubcarrierOffset) field in the SSB.

[0067] In this embodiment of the application, the fields can also be called parameters, such as the "ssb-SubcarrierOffset" parameter, the "pdcch-ConfigSIB1" parameter, etc.

[0068] Optionally, the value of Kssb is determined according to the configuration unit of the SSB in the CRB, wherein the configuration unit is N times the first SCS, and N is a number greater than 0. The base station can configure the SSB in the CRB according to the N times the first SCS, and the UE can search for the SSB according to the N times the first SCS.

[0069] Optionally, 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 can be [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

[0070] The first optional method: Indicating the value of Kssb through the subcarrier offset (ssb-SubcarrierOffset) field in the SSB and the system frame number (SFN) field in the physical broadcast channel PBCH payload can specifically include:

[0071] The value of Kssb is indicated by 4 bits in the subcarrier offset field of the SSB, and the value of Kssb is [0, 15]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field of the SSB and 1 high-order bit in the system frame number field of the physical broadcast channel PBCH payload, and the value of Kssb is [0, 15], [0, 23] or [0, 31 ... the physical broadcast channel PBCH payload PBCH payload PBCH payload, and the value of Kssb is [0, 15], [0, 23] or [0, 31]; The two high-order bits in the system frame number field of the BCH payload indicate that the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47] or [0, 63]; or the value of Kssb is indicated by the four bits in the subcarrier offset field of the SSB and the three high-order bits in the system frame number field of the physical broadcast channel PBCH payload, and the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

[0072] The value of Kssb is indicated by M bits in the system frame number field of the Physical Broadcast Channel (PBCH) payload. These M bits are added to the system frame number field of the Master Information Block (MIB) in the PBCH to represent the system frame number. The added M bits are represented by bits in the control resource set - zero (PDR - SIB1) field and / or the search space - zero (PDR - SIB1) field of the PDCCH configuration in the MIB, i.e., M bits are taken from the PDCCH configuration SIB1 field (a total of 8 bits) to represent the system frame number. M can be 1, 2, or 3.

[0073] For example, when M=1, the system frame number field in the MIB is expanded from 6 bits to 7 bits; when M=2, it is expanded from 6 bits to 8 bits; and when M=3, it is expanded from 6 bits to 9 bits. When the system frame number field in the MIB is expanded from 6 bits to 7 bits, the data in the PBCH arrives at the coding unit in 80ms increments; when it is expanded from 6 bits to 8 bits, the data in the PBCH arrives at the coding unit in 40ms increments; or when it is expanded from 6 bits to 9 bits, the data in the PBCH arrives at the coding unit in 20ms increments.

[0074] The second optional method: Specifically, the method of indicating the value of Kssb through the subcarrier offset (ssb-SubcarrierOffset) field and the PDCCH configuration system information block 1 (SIB1) (pdcch-ConfigSIB1) field in the SSB can include:

[0075] The value of Kssb is indicated by 4 bits in the subcarrier offset field, and the value of Kssb is [0, 15]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field and 1 bit in the PDCCH configuration SIB1 field, and the value of Kssb is [0, 15], [0, 23] or [0, 31]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field and 1 bit in the PDCCH configuration SIB1 field, and the value of Kssb is [0, 15], [0, 23] or [0, 31]; or the value of Kssb is indicated by 4 bits in the subcarrier offset field and the PDCCH configuration SIB1 field. The SIB1 field is configured with 2 bits indicating that the value of 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 and 3 bits in the PDCCH configuration SIB1 field, and the value of Kssb is [0, 15], [0, 23], [0, 31], [0, 47], [0, 63] or [0, 97].

[0076] The value of Kssb can be the Control Resource Set - Zero field or / and Index Space - Zero field indication in the SIB1 field configured via PDCCH. This includes:

[0077] First, the value of Kssb is indicated by controlling 1 high-order bit or 1 low-order bit in the resource set-zero field, or 1 high-order bit or 1 low-order bit in the search space-zero field.

[0078] Second, the value of Kssb is indicated by two high-order bits or two low-order bits in the control resource set-zero field, or two high-order bits or two low-order bits in the search space-zero field, or a total of two bits from both the control resource set-zero field and the search space-zero field. This total of two bits can consist of one high-order bit from the control resource set-zero field and one low-order bit from the search space-zero field, or it can consist of one low-order bit from the control resource set-zero field and one high-order bit from the search space-zero field.

[0079] Third, the value of Kssb is indicated by 3 high-order bits or 3 low-order bits in the control resource set-zero field, or 3 high-order bits or 3 low-order bits in the search space-zero field, or a total of 3 bits from both the control resource set-zero field and the search space-zero field. This total of 3 bits can consist of 2 high-order bits from the control resource set-zero field and 1 low-order bit from the search space-zero field, or it can consist of 2 low-order bits from the control resource set-zero field and 1 high-order bit from the search space-zero field.

[0080] The following analysis uses the example of determining the value of Kssb for the SCS combination of (SSB, CRB) as (120kHz, 480kHz) or (240kHz, 960kHz). The SCS of CRB is four times that of SSB.

[0081] For example, if the SCS combinations of (SSB, CRB) are (120kHz, 480kHz) or (240kHz, 960kHz), the SSB is configured in the CRB with one SCS of the SSB as the configuration unit.

[0082] like Figure 5 As shown, Figure 5 This is a schematic diagram of Kssb movement. With an SSB of 120kHz and a CRB of 480kHz, a CRB consists of 12 subcarriers, each with an SCS of 480kHz. The SSB's configuration unit (also called the movement unit or calculation unit) is 120kHz. Within a CRB subcarrier, the SSB needs to move 4 times to move from 0kHz to 480kHz, requiring 48 moves for 12 subcarriers. Each move increases the Kssb value by 1, therefore the Kssb value is [0, 47]. With an SSB of 240kHz and a CRB of 960kHz, a CRB consists of 12 subcarriers, each with an SCS of 960kHz. The SSB's configuration unit is 240kHz. Within a CRB subcarrier, the SSB needs to move 4 times to move from 0kHz to 960kHz, requiring 48 moves for 12 subcarriers. Each move increases the Kssb value by 1, therefore the Kssb value is [0, 47].

[0083] When the SCS of CRB is 4 times that of SSB, i.e. (SSB, CRB): (120kHz, 480kHz) and (240kHz, 960kHz), the representation of Kssb is shown in Table 3.

[0084] SSB CRB The value of Kssb Use bits Unit of Calculation 120kHz 480kHz 0:47 6-bits 120kHz (SSB) 240kHz 960kHz 0:47 6-bits 240kHz (SSB)

[0085] Table 3

[0086] Since Kssb has a value of [0, 47], it requires 6 bits to represent. The 6 bits of Kssb can be indicated as follows.

[0087] (1) The value of Kssb is indicated by the system frame number (SFN) (2 bits) in the ssb-SubcarrierOffset (4 bits) + PBCH payload. Furthermore, it can be indicated by the most significant bit (MSB) of the SFN in the PBCH payload.

[0088] At this point, for the broadcast channel, the data in the PBCH arrives at the coding unit in 40ms increments. Since 2 bits from the system frame number field in the PBCH payload are used to represent the Kssb value, 2 bits need to be added to the system frame number field in the main information block (MIB) of the PBCH to represent the system frame number, thus expanding the system frame number field in the MIB from 6 bits to 8 bits. These 2 added bits can be represented by bits in the control resource set - zero and / or search space - zero in the PDCCH configuration SIB1 field of the main information block (MIB), i.e., 2 bits are taken from the PDCCH configuration SIB1 field (a total of 8 bits). This includes the following methods:

[0089] The first option is any 2 bits from the "controlResourceSetZero" field or the "searchSpaceZero" field, such as 2 high-order bits or 2 low-order bits.

[0090] The second method uses one high-order bit from the "controlResourceSetZero" field plus one high-order bit from the "searchSpaceZero" field.

[0091] The third option is a combination of 1 high-order bit in the "controlResourceSetZero" field and 1 low-order bit in the "searchSpaceZero" field.

[0092] The fourth type consists of 1 low-order bit in the "controlResourceSetZero" field and 1 high-order bit in the "searchSpaceZero" field.

[0093] The fifth option is to use 1 low-order bit from the "controlResourceSetZero" field plus 1 low-order bit from the "searchSpaceZero" field.

[0094] (2) The value of Kssb is indicated by ssb-SubcarrierOffset (4 bits) + pdcch-ConfigSIB1 (2 bits). The pdcch-ConfigSIB1 field can include the "controlResourceSetZero" and "searchSpaceZero" fields. The 2 bits in the "pdcch-ConfigSIB1" field can be indicated as follows:

[0095] The first option is any 2 bits from the "controlResourceSetZero" field or the "searchSpaceZero" field, such as 2 high-order bits or 2 low-order bits.

[0096] The second method uses one high-order bit from the "controlResourceSetZero" field plus one high-order bit from the "searchSpaceZero" field.

[0097] The third option is a combination of 1 high-order bit from the "controlResourceSetZero" field and 1 low-order bit from the "searchSpaceZero" field.

[0098] The fourth type is composed of 1 low-order bit in the "controlResourceSetZero" field and 1 high-order bit in the "searchSpaceZero" field.

[0099] The fifth option is 1 low-order bit from the "controlResourceSetZero" field plus 1 low-order bit from the "searchSpaceZero" field.

[0100] Example 2: When the SCS combinations of (SSB, CRB) are (120kHz, 480kHz) or (240kHz, 960kHz), the SSB is configured in the CRB with twice the SCS of the SSB as the configuration unit.

[0101] like Figure 6 As shown, Figure 6This is a schematic diagram of Kssb movement. With an SSB of 120kHz and a CRB of 480kHz, a CRB consists of 12 subcarriers, each with an SCS of 480kHz. The SSB configuration unit (also called the movement unit or calculation unit) is 240Hz. Within a CRB subcarrier, the SSB needs to move twice to move from 0kHz to 480kHz; for 12 subcarriers, this requires 24 moves. Each move increases the Kssb value by 1, therefore the Kssb value is [0, 23]. Similarly, with an SSB of 240kHz and a CRB of 960kHz, a CRB consists of 12 subcarriers, each with an SCS of 960kHz. The SSB configuration unit is 480kHz. Within a CRB subcarrier, the SSB needs to move twice to move from 0kHz to 960kHz; for 12 subcarriers, this requires 24 moves. Each move increases the Kssb value by 1, therefore the Kssb value is [0, 23].

[0102] When the SCS of CRB is 4 times that of SSB, i.e. (SSB, CRB): (120kHz, 480kHz) and (240kHz, 960kHz), the representation of Kssb is shown in Table 4.

[0103] SSB CRB scope Use bits Unit of Calculation 120kHz 480kHz 0:23 5-bits 240kHz 240kHz 960kHz 0:23 5-bits 480kHz

[0104] Table 4

[0105] Since Kssb takes values ​​of [0, 23], it requires 5 bits to represent. The 5 bits of Kssb can be indicated as follows.

[0106] (1) The value of Kssb is indicated by the system frame number (SFN) (1-bit) in the ssb-SubcarrierOffset (4-bits) + PBCH payload. Furthermore, it can be indicated by the most significant bit (MSB) of the SFN in the PBCH payload.

[0107] At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in 80ms increments. Since 1 bit in the system frame number field of the PBCH payload is used to represent the value of Kssb, 1 bit needs to be added to the system frame number field in the main information block (MIB) of the PBCH to represent the system frame number, thus expanding the system frame number field in the MIB from 6 bits to 7 bits.

[0108] The newly added bit can be a bit representation from the control resource set - zero (controlResourceSetZero) or search space - zero (searchSpaceZero) in the PDCCH configuration SIB1 field of the main information block MIB. That is, one bit is taken from the PDCCH configuration SIB1 field (a total of 8 bits). The newly added bit can be any one bit from the "controlResourceSetZero" field or the "searchSpaceZero" field. For example, it could be one high-order bit or one low-order bit from the "controlResourceSetZero" field, or one high-order bit or one low-order bit from the "searchSpaceZero" field.

[0109] (2) The value of Kssb is indicated by ssb-SubcarrierOffset (4 bits) + pdcch-ConfigSIB1 (1 bit). The pdcch-ConfigSIB1 field can include the "controlResourceSetZero" field and the "searchSpaceZero" field. The 1 bit can be any 1 bit of pdcch-ConfigSIB1. For example, it can be either a high-order bit or a low-order bit in the "controlResourceSetZero" field, or either a high-order bit or a low-order bit in the "searchSpaceZero" field.

[0110] Example 3: The following analysis uses the SCS combination (SSB, CRB) of (120kHz, 960kHz) to determine the value of Kssb. The SCS of CRB is 8 times that of SSB.

[0111] When the SCS combination of (SSB, CRB) is (120kHz, 960kHz), the SSB is configured in the CRB according to the configuration unit of the SCS of a single SSB.

[0112] like Figure 7 As shown, Figure 7 This is a schematic diagram of Kssb movement. With SSB at 120kHz and CRB at 960kHz, a CRB consists of 12 subcarriers, and the SSB of a subcarrier is 960kHz. The configuration unit (also called the movement unit or calculation unit) of SSB is 120kHz. In a subcarrier of CRB, the SSB needs to move 8 times to move from 0kHz to 960kHz. For 12 subcarriers, it needs to move 96 times. Each time it moves, the value of Kssb increases by 1. Therefore, the value of Kssb is [0, 95].

[0113] When the SCS of CRB is 8 times that of SSB, i.e. (SSB, CRB): (120kHz, 960kHz), the representation of Kssb is shown in Table 5.

[0114] SSB CRB scope Use bits Unit of Calculation 120kHz 960kHz 0:95 7-bits 120kHz (SSB)

[0115] Table 5

[0116] Since Kssb has a value of [0, 95], it requires 7 bits to represent. The 7 bits of Kssb can be indicated as follows.

[0117] (1) The value of Kssb is indicated by the system frame number (SFN) (3 bits) in the ssb-SubcarrierOffset (4 bits) + PBCH payload. Furthermore, it can be indicated by the 3 most significant bits (MSB) of the SFN in the PBCH payload.

[0118] At this point, for the broadcast channel, the data in the PBCH arrives at the coding unit in 20ms increments. Since the 3 bits in the system frame number field of the PBCH payload are used to represent the value of Kssb, 3 bits need to be added to the system frame number field in the main information block (MIB) of the PBCH to represent the system frame number, thus expanding the system frame number field in the MIB from 6 bits to 9 bits. These 3 added bits can be represented by bits in the control resource set - zero and / or search space - zero in the PDCCH configuration SIB1 field of the main information block (MIB), i.e., 3 bits are taken from the PDCCH configuration SIB1 field (a total of 8 bits). This includes the following methods:

[0119] The first option is any 3 bits from the "controlResourceSetZero" field or the "searchSpaceZero" field, such as 3 high-order bits or 3 low-order bits.

[0120] The second option is any 2 bits from the "controlResourceSetZero" field plus any 1 bit from the "searchSpaceZero" field.

[0121] The third option is any 1 bit from the "controlResourceSetZero" field plus any 2 bits from the "searchSpaceZero" field.

[0122] (2) The value of Kssb is indicated by ssb-SubcarrierOffset (4 bits) + pdcch-ConfigSIB1 (3 bits). The pdcch-ConfigSIB1 field can include the "controlResourceSetZero" and "searchSpaceZero" fields. The 3 bits in the "pdcch-ConfigSIB1" field can be indicated as follows:

[0123] The first method is to use any 3 bits from the "controlResourceSetZero" field within the "pdcch-ConfigSIB1" field, such as 3 high-order bits or 3 low-order bits in the "controlResourceSetZero" field.

[0124] The second method is to use any 3 bits in the "searchSpaceZero" field of the "pdcch-ConfigSIB1" field, such as 3 high-order bits or 3 low-order bits in the "searchSpaceZero" field.

[0125] The third method uses a combination of 3 bits from the fields "controlResourceSetZero" and "searchSpaceZero" in the field "pdcch-ConfigSIB1", including:

[0126] 1. Two high-order bits in the “controlResourceSetZero” field + one high-order bit in the “searchSpaceZero” field;

[0127] 2. Two high-order bits in the "controlResourceSetZero" field + one low-order bit in the "searchSpaceZero" field;

[0128] 3. One high-order bit in the “controlResourceSetZero” field + two high-order bits in the “searchSpaceZero” field;

[0129] 4. One high-order bit in the "controlResourceSetZero" field + two low-order bits in the "searchSpaceZero" field;

[0130] 5. One low-order bit in the "controlResourceSetZero" field + two high-order bits in the "searchSpaceZero" field;

[0131] 6. One low-order bit in the "controlResourceSetZero" field + two low-order bits in the "searchSpaceZero" field;

[0132] 7. Two low-order bits in the “controlResourceSetZero” field + one high-order bit in the “searchSpaceZero” field;

[0133] 8. Two low-order bits in the “controlResourceSetZero” field + one low-order bit in the “searchSpaceZero” field.

[0134] Example 4: When the SCS combination of (SSB, CRB) is (120kHz, 960kHz), configure the SSB in the CRB according to the configuration unit of 2 or 4 times the SCS of the SSB.

[0135] like Figure 8 As shown, Figure 8 This is a schematic diagram of Kssb movement. With an SSB of 120kHz and a CRB of 960kHz, one CRB consists of 12 subcarriers, and the SCS of one subcarrier is 960kHz. When the SSB configuration unit is 240Hz, moving the SSB from 0kHz to 960kHz within one subcarrier of the CRB requires 4 moves; for 12 subcarriers, this requires 48 moves. Each move increases the Kssb value by 1, resulting in a Kssb value of [0, 47]. When the SSB configuration unit is 480Hz, moving the SSB from 0kHz to 960kHz within one subcarrier of the CRB requires 2 moves; for 12 subcarriers, this requires 24 moves. Each move increases the Kssb value by 1, resulting in a Kssb value of [0, 23]. It can be seen that compared to the case where SSBs are placed in 240kHz units, when SSBs are placed in 480kHz units, the SSBs are more sparse in the frequency domain.

[0136] When the SCS of CRB is 8 times that of SSB, i.e. (SSB, CRB): (120kHz, 960kHz), the representation of Kssb is shown in Table 6.

[0137] SSB CRB scope Use bits Unit of Calculation 120kHz 960kHz 0:47 6-bits 240kHz 120kHz 960kHz 0:23 5-bits 480kHz

[0138] Table 6

[0139] When the SCS combination of (SSB, CRB) is (120kHz, 960kHz), and the SSB is placed in the CRB according to a configuration unit of 240kHz, the value of Kssb is [0, 47], which is represented by 6 bits. The 6 bits of the Kssb value can be indicated as follows:

[0140] (1) The value of Kssb is indicated by the system frame number (SFN) (2 bits) in the ssb-SubcarrierOffset (4 bits) + PBCH payload. Furthermore, it can be indicated by the most significant bit (MSB) of the SFN in the PBCH payload.

[0141] At this point, for the broadcast channel, the data in the PBCH arrives at the coding unit in 40ms increments. Since 2 bits from the system frame number field in the PBCH payload are used to represent the Kssb value, 2 bits need to be added to the system frame number field in the main information block (MIB) of the PBCH to represent the system frame number, thus expanding the system frame number field in the MIB from 6 bits to 8 bits. These 2 added bits can be represented by bits in the control resource set - zero and / or search space - zero in the PDCCH configuration SIB1 field of the main information block (MIB), i.e., 2 bits are taken from the PDCCH configuration SIB1 field (a total of 8 bits). The 2 added bits can include the following indication methods:

[0142] The first option is any 2 bits from the "controlResourceSetZero" field or the "searchSpaceZero" field, such as 2 high-order bits or 2 low-order bits.

[0143] The second method uses one high-order bit from the "controlResourceSetZero" field plus one high-order bit from the "searchSpaceZero" field.

[0144] The third option is a combination of 1 high-order bit in the "controlResourceSetZero" field and 1 low-order bit in the "searchSpaceZero" field.

[0145] The fourth type consists of 1 low-order bit in the "controlResourceSetZero" field and 1 high-order bit in the "searchSpaceZero" field.

[0146] The fifth option is to use 1 low-order bit from the "controlResourceSetZero" field plus 1 low-order bit from the "searchSpaceZero" field.

[0147] (2) The value of Kssb is indicated by ssb-SubcarrierOffset (4 bits) + pdcch-ConfigSIB1 (2 bits). The pdcch-ConfigSIB1 field can include the "controlResourceSetZero" and "searchSpaceZero" fields. The 2 bits in the "pdcch-ConfigSIB1" field can be indicated as follows:

[0148] The first option is any 2 bits from the "controlResourceSetZero" field or the "searchSpaceZero" field, such as 2 high-order bits or 2 low-order bits.

[0149] The second method uses one high-order bit from the "controlResourceSetZero" field plus one high-order bit from the "searchSpaceZero" field.

[0150] The third option is a combination of 1 high-order bit in the "controlResourceSetZero" field and 1 low-order bit in the "searchSpaceZero" field.

[0151] The fourth type consists of 1 low-order bit in the "controlResourceSetZero" field and 1 high-order bit in the "searchSpaceZero" field.

[0152] The fifth option is to use 1 low-order bit from the "controlResourceSetZero" field plus 1 low-order bit from the "searchSpaceZero" field.

[0153] When the SCS combination of (SSB, CRB) is (120kHz, 960kHz), and the SSB is placed in the CRB according to a configuration unit of 480kHz, the value of Kssb is [0, 23], which is represented by 5 bits. The 5 bits of the Kssb value can be indicated as follows:

[0154] (1) The value of Kssb is indicated by the system frame number (SFN) (1-bit) in the ssb-SubcarrierOffset (4-bits) + PBCH payload. Furthermore, it can be indicated by the most significant bit (MSB) of the SFN in the PBCH payload.

[0155] At this time, for the broadcast channel, the data in the PBCH arrives at the coding unit in 80ms increments. Since 1 bit in the system frame number field of the PBCH payload is used to represent the value of Kssb, 1 bit needs to be added to the system frame number field in the main information block (MIB) of the PBCH to represent the system frame number, thus expanding the system frame number field in the MIB from 6 bits to 7 bits.

[0156] The newly added bit can be a bit representation from the control resource set - zero (controlResourceSetZero) or search space - zero (searchSpaceZero) in the PDCCH configuration SIB1 field of the main information block MIB. That is, one bit is taken from the PDCCH configuration SIB1 field (a total of 8 bits). The newly added bit can be any one bit from the "controlResourceSetZero" field or the "searchSpaceZero" field. For example, it could be one high-order bit or one low-order bit from the "controlResourceSetZero" field, or one high-order bit or one low-order bit from the "searchSpaceZero" field.

[0157] (2) The value of Kssb is indicated by ssb-SubcarrierOffset (4 bits) + pdcch-ConfigSIB1 (1 bit). The pdcch-ConfigSIB1 field can include the "controlResourceSetZero" field and the "searchSpaceZero" field. The 1 bit can be any 1 bit of pdcch-ConfigSIB1. For example, it can be either a high-order bit or a low-order bit in the "controlResourceSetZero" field, or either a high-order bit or a low-order bit in the "searchSpaceZero" field.

[0158] It should be noted that for cases where the SSB is configured in the CRB using the first SCS as the configuration unit according to other multiples, the situation is similar to the above, and will not be described again in this application.

[0159] Optionally, SSBs can be configured within the CRB using frequency division multiplexing. That is, a CRB includes multiple SSBs. Further, the multiple SSBs include a first SSB and a second SSB, where the first SSB is the first SSB within the CRB, and the second SSB is located at a higher frequency position within the CRB relative to the first SSB. The Kssb corresponding to the first SSB is k. ssb_1 The Kssb corresponding to the second SSB is k ssb_m The k ssb_1 and the k ssb_m satisfy:

[0160]

[0161] Wherein, u1 is the second carrier spacing, u2 is the first subcarrier spacing, and N is the number of equal parts into which the frequency domain of the CRB is divided.

[0162] Example 1: When the SCS combinations of (SSB, CRB) are (120kHz, 480kHz) or (240kHz, 960kHz), the SSB is configured within the CRB at 120kHz. The SCS of the CRB is four times that of the SSB. A CRB includes 12 subcarriers. Without frequency division multiplexing, the Kssb value is [0, 47], represented by 6 bits. With frequency division multiplexing, the CRB is divided into N equal parts, with each SSB located within each 1 / N portion of the CRB. The relationship between the offset Kssb value and the number of bits used between each SSB and CRB subcarrier #0 and N is shown in Table 7 below.

[0163] N equal parts (N) Number of bits 2 5 3 4

[0164] 4 4

[0165] Table 7

[0166] When using 5 bits to represent the value of Kssb, it can be represented in one of the following two ways:

[0167] (a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

[0168] (b) ssb-SubcarrierOffset field (4-bits) + pdcch-ConfigSIB1 field (1-bits).

[0169] Among them, the k of the SSB coexisting with FDM at higher frequency domain positions ssb_m The calculation method is as follows:

[0170]

[0171] Wherein, "12" indicates that a CRB contains 12 subcarriers, u1 represents the subcarrier spacing of the CRB, and u2 represents the subcarrier spacing of the SSB. This indicates that an SCS used by the CRB is an SCS used by the SSB in the frequency domain. times, k ssb_1 This refers to the SSB located in a lower frequency domain.

[0172] For k ssb_1 and k ssb_m One way to achieve this relationship is:

[0173] The k configured by the base station for the UE ssb_1 and k ssb_m The bits are the same, and therefore the UE calculates k. ssb_1 and k ssb_m The values ​​are the same. The offset between the SSB and CRB subcarrier #0 at the higher frequency domain position is determined by the formula... calculate.

[0174] For example, such as Figure 9 As shown, with the SCS of (SSB, CRB) being (120kHz, 480kHz), the SSB is placed in units of 120kHz. With N=2, the two SSBs at 120kHz are located in the upper and lower halves of the 480kHz CRB, respectively. SSB#1 is located between subcarriers #0 and #5 in a CRB, and SSB#2 is located between subcarriers #6 and #11 in a CRB. When the base station is configured with bits "00111", k ssb_1 and k ssb_2 The values ​​are 7, meaning that the lowest frequency position of SSB#1 is offset from subcarrier #0 in CRB by 7 120kHz subcarriers, while the lowest frequency position of SSB#2 is offset from subcarrier #0 in CRB by 31 (24+7) 120kHz subcarriers.

[0175] The above method also applies to the case where the SCS combination of (SSB, CRB) is (240kHz, 960kHz), which will not be elaborated here.

[0176] When SSBs are configured in the frequency division multiplexing manner, at least one SSB among multiple FDM SSBs is a cell-define SSB (CD-SSB), and the other SSBs can be NCD-SSB or CD-SSB.

[0177] The offset between the SSB and CRB subcarrier #0 of the FDM satisfies the following two conditions:

[0178] (1)

[0179] (2) k configured in the base station ssb_1 and k ssb_m The values ​​are the same.

[0180] When the first SSB detected by the UE is NCD-SSB, the UE can use Kssb (where Kssb can be the k corresponding to the first SSB) as a reference. ssb_1 Or the k corresponding to the last SSB ssb_m The value of ) can be used to deduce the frequency domain location of another SSB. This includes: or For example, such as Figure 8 As shown, when m=2, u1=480kHz, u2=120kHz, N=2, and the value of Kssb detected by the UE is "7" (corresponding to bit "00111"), the SSB can be searched at the following two frequency domain locations:

[0181] (1) Assuming the UE detects SSB#1, the frequency domain location of SSB#2 is:

[0182] (2) Assuming the UE detects SSB#2, then the frequency domain location of SSB#1 is:

[0183] Example 2: When the SCS combinations of (SSB, CRB) are (120kHz, 960kHz), the SSB is configured within the CRB at 120kHz. The SCS of the CRB is 8 times that of the SSB. A CRB includes 12 subcarriers. Without frequency division multiplexing, the Kssb value is [0, 95], represented by 7 bits. With frequency division multiplexing, the CRB is divided into N equal parts, with each SSB located within each 1 / N portion of the CRB. The relationship between the offset Kssb value and the number of bits used between each SSB and CRB subcarrier #0 and N is shown in Table 8 below.

[0184] N equal parts (N) Number of bits 2 6 3，4 5 6 4

[0185] Table 8

[0186] First, when using 6 bits to indicate the value of Kssb, only 2 SSBs can be placed in a 960kHz CRB. Each SSB is located in subcarriers #0 to #5 and #6 to #11 of the 960kHz CRB, respectively, and the corresponding 120kHz subcarrier numbers are subcarriers #0 to #47 and #48 to #95.

[0187] The 6 bits are represented in one of the following two ways:

[0188] (a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (2-bits).

[0189] (b) ssb-SubcarrierOffset field (4-bits) + pdcch-ConfigSIB1 field (2-bits).

[0190] Among them, the distance between the SSB coexisting in the FDM mode at a higher frequency position (such as SSB#2) and the subcarrier #0 in the current CRB, i.e., k ssb_2 The specific calculation method is as follows: k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0191] Second, when using 5 bits to indicate the value of Kssb, these 5 bits are represented in one of the following two ways:

[0192] (a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

[0193] (b) ssb-SubcarrierOffset field (4-bits) + pdcch-ConfigSIB1 field (1-bits).

[0194] Within a 960kHz CRB, three or four SSBs can be placed, including:

[0195] (1) When a CRB supports the coexistence of 3 FDM SSBs, each SSB is located on subcarriers #0-#3, #4-#7, and #8-#11 of the 960kHz CRB, respectively. The corresponding 120kHz subcarrier numbers are subcarriers #0-#31, #32-#63, and #64-#95. The specific calculation method for the interval Kssb between the higher frequency SSB and subcarrier #0 of the CRB is as follows: N = 3, m = 2 or 3. k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0196] (2) When a CRB supports the coexistence of 4 FDM SSBs, each SSB is located on subcarriers #0-#2, #3-#5, #6-#8, and #9-#11 of the 960kHz CRB, respectively. The corresponding 120kHz subcarrier numbers are subcarriers #0-#23, #24-#47, #48-#71, and #72-#95. The specific calculation method for the interval Kssb between the higher frequency SSB and subcarrier #0 of the CRB is as follows: N = 4, m = 2, 3, or 4. k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0197] Third, when using 4 bits to indicate the value of Kssb, it is represented by the ssb-SubcarrierOffset field (4 bits).

[0198] Within a 960kHz CRB, six SSBs can be placed. When a CRB supports the coexistence of six FDM SSBs, each SSB is located on subcarriers #0 to #1, #2 to #3, #4 to #5, #6 to #7, #8 to #9, and #10 to #11 of the 960kHz CRB. The corresponding 120kHz subcarrier numbers are #0 to #15, #16 to #31, #32 to #47, #48 to #63, #64 to #79, and #80 to #95. The specific calculation method for the interval Kssb between the higher-frequency SSB and subcarrier #0 of the CRB is as follows: N = 6, m = 1, 2, 3, 4, or 5. k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0199] For k ssb_1 and k ssb_m One way to realize the relationship is: k ssb_1 and k ssb_m The values ​​are the same, meaning the base station configures the terminal to instruct the terminal to calculate k. ssb_1 and k ssb_m The bits are the same.

[0200] For the case of SSBs placed in FDM, at least one SSB among multiple FDMs is a CD-SSB, and the remaining SSBs are either NCD-SSBs or CD-SSBs.

[0201] When the offset between different SSBs and CRB subcarrier #0 satisfies the following two conditions:

[0202] (1) (2) k configured in the base station ssb_1 and k ssb_m The values ​​are the same.

[0203] When the first SSB detected by the UE is NCD-SSB, the UE can use Kssb (where Kssb can be the k corresponding to the first SSB) as a reference. ssb_1 Or the k corresponding to the last SSB ssb_m The value of ) can be used to deduce the frequency domain location of another SSB. This includes: or

[0204] Example 3: In the case where the SCS combinations of (SSB, CRB) are (120kHz, 960kHz), the SSB is configured within the CRB at 240kHz. A CRB consists of 12 subcarriers. Without frequency division multiplexing, the value of Kssb is [0, 47], represented by 6 bits. With frequency division multiplexing, the CRB is divided into N equal parts, with each SSB located within each 1 / N portion of the CRB. The relationship between the offset Kssb value and the number of bits used between each SSB and CRB subcarrier #0 and N is shown in Table 9.

[0205] N equal parts (N) Number of bits 3 4 2 5

[0206] Table 9

[0207] When using 4 bits to indicate the value of Kssb, it is represented by the ssb-SubcarrierOffset field (4 bits). Within a 960kHz CRB, only 3 SSBs can be placed. Each SSB is located in subcarriers #0 to #3, #4 to #7, and #8 to #11 of the 960kHz CRB. The corresponding 120kHz subcarrier numbers are subcarriers #0 to #15, #16 to #31, and #32 to #47, respectively.

[0208] The specific calculation method for 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 ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0209] When using 5 bits to indicate the value of Kssb, these 5 bits are represented in one of the following two ways:

[0210] (a) ssb-SubcarrierOffset field (4-bits) + SFN in PBCH payload field (1-bits).

[0211] (b) ssb-SubcarrierOffset field (4-bits) + pdcch-ConfigSIB1 field (1-bits).

[0212] Within a 960kHz CRB, only two SSBs can be placed. Each SSB is located in subcarriers #0 to #5 and #6 to #11 of the 960kHz CRB, respectively. The corresponding 120kHz subcarrier numbers are subcarriers #0 to #47 and #48 to #95.

[0213] The specific calculation method for Kssb, the interval between the higher-frequency SSB and the subcarrier #0 of the CRB, is as follows: N = 2, m = 2. k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0214] For k ssb_1 and k ssb_m One way to achieve this relationship is:

[0215] k ssb_1 and k ssb_m The values ​​are the same, that is, the base station configures the terminal to instruct the terminal to calculate k. ssb_1 and k ssb_m The bits are the same.

[0216] For the case of SSBs placed in FDM, at least one SSB among multiple FDMs is a CD-SSB, and the remaining SSBs are either NCD-SSBs or CD-SSBs.

[0217] When the offset between different SSBs and CRB subcarrier #0 satisfies the following two conditions:

[0218] (1) (2) k configured in the base station ssb_1 and k ssb_m The values ​​are the same.

[0219] When the first SSB detected by the UE is NCD-SSB, the UE can use Kssb (where Kssb can be the k corresponding to the first SSB) as a reference. ssb_1 Or the k corresponding to the last SSB ssb_m The value of ) can be used to deduce the frequency domain location of another SSB. This includes: or

[0220] Example 4: For the SCS combination of (SSB, CRB) being (120kHz, 960kHz), the SSB is configured within the CRB at 480kHz. Each SSB in... The range is shifted, N=2, meaning the CRB is divided into N equal parts. The specific calculation method for the interval Kssb between the higher frequency SSB and the CRB subcarrier #0 is as follows: N = 2, m = 2. k ssb_1 This indicates the spacing between the SSB and CRB subcarrier #0, which are located in the lower frequency band.

[0221] For k ssb_1 and k ssb_mOne way to realize the relationship is: k ssb_1 and k ssb_m The values ​​are the same, meaning the base station configures the UE to indicate k. ssb_1 and k ssb_m The bits are the same.

[0222] For the case of SSBs placed in FDM, at least one SSB among multiple FDM SSBs must be a CD-SSB, and the remaining SSBs must be either NCD-SSBs or CD-SSBs. The offset between different SSBs and CRB subcarrier #0 must satisfy the following two conditions:

[0223] (1)

[0224] (2) k configured in the base station ssb_1 and k ssb_m The values ​​are the same.

[0225] When the first SSB detected by the UE is NCD-SSB, the UE can use Kssb (where Kssb can be the k corresponding to the first SSB) as a reference. ssb_1 Or the k corresponding to the last SSB ssb_m The value of ) can be used to deduce the frequency domain location of another SSB. This includes: or

[0226] A third option is to indicate the value of Kssb using 1 or 2 bits in the subcarrier offset (ssb-SubcarrierOffset) field of the SSB, where the 1 bit in the subcarrier offset (ssb-SubcarrierOffset) field is either 1 high-order bit or 1 low-order bit in the subcarrier offset field. Alternatively, the 2 bits in the subcarrier offset field are either 2 high-order bits or 2 low-order bits in the subcarrier offset field.

[0227] Optionally, 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 value of Kssb is [0, 1] or [0, 2].

[0228] The remaining bits in the subcarrier offset field of the SSB are used to represent the Q value, which 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 between the Master Information Block (MIB) of licensed frequency bands and the MIB of unlicensed frequency bands; or the remaining bits in the subcarrier offset field of the SSB are used to indicate the interval between multiple PDCCHs carrying control resource sets that have a quasi-co-location relationship with the SSB, or to indicate that the terminal device listens to the PDCCH at one or more listening times. Optionally, the Q value is 1, 2, 4, 8, 16, 32, or 64.

[0229] For example, in the case of an SCS combination of (SSB, CRB) of (480kHz, 120kHz), the SCS of a subcarrier of CRB is 120kHz, and the configuration unit of SSB is 480Hz. Within CRB, the SSB needs to move 3 times to move from the 1st subcarrier to the 12th subcarrier. Each time it moves, the value of Kssb increases by 1, so the value of Kssb is [0, 2]. Alternatively, in the case of an SCS combination of (SSB, CRB) of (960kHz, 240kHz), the SCS of a subcarrier of CRB is 240kHz, and the configuration unit of SSB is 960Hz. Within CRB, the SSB needs to move 3 times to move from the 1st subcarrier to the 12th subcarrier. Each time it moves, the value of Kssb increases by 1, so the value of Kssb is [0, 2]. With an SSB of 960kHz and a CRB of 120kHz, the SCS of a CRB subcarrier is 120kHz, and the configuration unit of the SSB is 960kHz. Within the CRB, the SSB needs to move twice to move from the 1st subcarrier to the 12th subcarrier. Each time it moves, the value of Kssb increases by 1, so the value of Kssb is [0, 1]. The representation of Kssb for the above three cases is shown in Table 10.

[0230] SSB CRB Value Use bits Unit of Calculation 480kHz 120kHz 0:2 2-bits 480kHz (SSB) 960kHz 240kHz 0:2 2-bits 960kHz (SSB) 960kHz 120kHz 0:1 1-bits 960kHz (SSB)

[0231] Table 10

[0232] As shown in Table 10, when the SCS combination of (SSB, CRB) is (480kHz, 120kHz), the SSB is placed in units of 480kHz. When the SCS combination of (SSB, CRB) is (960kHz, 240kHz), the SSB is placed in units of 960kHz. Therefore, the value of Kssb is 0 to 2, using 2 bits, represented by any 2 bits in the "ssb-SubcarrierOffset" field, such as 2 high-order bits or 2 low-order bits.

[0233] The “ssb-SubcarrierOffset” field contains 2 bits indicating the value of Kssb, and the remaining 2 bits can be used to indicate other information, including:

[0234] (1) Use at least 1 bit to indicate the Q value, where the Q value is expanded from (1, 2, 4, 8) to (1, 2, 4, 8, 16, 32, 64).

[0235] (2) Differentiate between licensed and unlicensed MIBs. The contents of licensed and unlicensed MIBs differ. In unlicensed bands, the "subCarrierSpacingCommon" and "LSB ofssb-SubcarrierOffset" fields in the MIB jointly represent the Q value.

[0236] (3) Indicate the offset between multiple PDCCHs carrying CORESET#0 that have a QCL relationship with the current SSB, or instruct the UE to listen to PDCCHs carrying CORESET#0 at multiple listening positions that have a QCL relationship with a certain SSB.

[0237] As shown in Table 10, when the SCS combination of (SSB, CRB) is (120kHz, 960kHz), the SSB is placed in units of 960kHz. Therefore, the value of Kssb is 0 to 1, using 1 bit, which is represented by any 1 bit in the "ssb-SubcarrierOffset" field, such as 1 high-order bit or 1 low-order bit.

[0238] The "ssb-SubcarrierOffset" field contains one bit indicating the value of Kssb, and the remaining three bits can be used to indicate other information, including:

[0239] (1) Use at least 1 bit to indicate the Q value, in which case the value of Q is expanded from (1, 2, 4, 8) to (1, 2, 4, 8, 16, 32, 64);

[0240] (2) Distinguish between licensed frequency bands and unlicensed frequency bands in MIB.

[0241] (3) Indicate the offset between multiple PDCCHs carrying CORESET#0 that have a QCL relationship with the current SSB, or instruct the UE to listen to PDCCHs carrying CORESET#0 at multiple listening positions that have a QCL relationship with a certain SSB.

[0242] In this embodiment, by introducing a new SCS, under different SCS combinations of SSB and CRB, the value of Kssb is indicated by the subcarrier offset field in the SSB and the system frame number field in the Physical Broadcast Channel (PBCH) payload; or by the subcarrier offset field in the SSB and the PDCCH configuration system information block 1 field; or by 1 or 2 bits in the subcarrier offset field of the SSB, with the remaining bits used to indicate other information. This improves the accuracy of SSB detection by the terminal device.
