[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410395853.3 filed in China on April 2, 2024, the entire contents of which are incorporated herein by reference. Technical Field

Background Art

[0004] During the process of data transmission between User Equipment (UE) and the network, System Information (SI) can provide the UE with the necessary information for connecting to the network. Among them, SI can include Master Information Block (MIB) and System Information Block (SIB). Unlike the MIB broadcasted in the Physical Broadcast Channel (PBCH), all SIBs are broadcasted in the Physical Downlink Shared Channel (PDSCH). Among these SIBs, System Information Block Type 1 (SIB1) can include scheduling information of other SIBs, so the reception of SIB1 is very important for the UE.

[0005] Currently, to minimize data transmission power consumption, UEs can receive SIB1 via a Network Energy Savings (NES) cell in the on-demand SIB1 state. That is, NES cells do not actively send SIB1, but only send SIB1 after being triggered by an uplink wake-up signal (UL-WUS), thereby reducing power consumption.

[0006] However, the UE needs to determine the location of the common search space set of the NES cell before it can obtain the SIB scheduling information and receive SIB 1. Therefore, how the UE determines the location of the common search space set of the NES cell is an urgent problem to be solved. Summary of the Invention

[0041] Some terms and nouns involved in the embodiments of this application are explained below.

[0042] 1. Cell-defining SSB (CD-SSB) and non-cell-defining SSB (NCD-SSB)

[0043] In New Radio (NR) systems, the CD-SSB is defined as the SSB associated with SIB1, also known as the Remaining Minimum System Information (RMSI). SIB1 defines the scheduling information for other SIBs and contains information for initial UE access. The frequency location of the CD-SSB must be on the system synchronization grid.

[0044] The NCD-SSB is correspondingly defined as an SSB that is not associated with SIB1. The NCD-SSB can be used for secondary cell synchronization and can also be used as a measurement signal configured for the UE. The NCD-SSB is not necessarily located on the system synchronization grid. If the NCD-SSB is located on the system synchronization grid, the information it carries can indicate the Global Synchronization Channel Number (GSFN) of the CD-SSB, as follows:

[0045] The PBCH channel data consists of 32 bits in total, of which bits 0 to 23 come from the Radio Resource Control (RRC) layer and bits 24 to 31 come from the Physical (PHY) layer.

[0046] The information carried in the RRC layer includes PDCCH-ConfigSIB1, and PDCCH-ConfigSIB1 carries information of CORESET 0 and search space 0.

[0047] The information carried by the PHY layer is: the lower 4 bits of the system frame number, a total of 4 bits; the 5ms half-frame number, a total of 1 bit; the beam identification number, or the highest bit of kSSB (1 bit) + the beam identification number (2 bits), a total of 3 bits.

[0048] kSSB is the subcarrier offset between the SSB and CORESET 0, which can be indicated by the SSB's subcarrier offset information field ssb-SubcarrierOffset. The subcarrier offset ranges include 0-23 and 0-11 subcarriers, respectively, using 5 bits (4 bits indicated by ssb-SubcarrierOffset and the 1 most significant bit indicated by the PBCH PHY layer) and 4 bits, corresponding to frequency range (FR) 1 and FR2. 4 bits can represent 16 values, while FR2's kSSB uses only 12 values ​​(0-11). 5 bits can represent 32 values, while FR1's kSSB uses only 24 values ​​(0-23). ​​Therefore, the remaining values ​​are completely unused, resulting in waste. To this end, the 3rd Generation Partnership Project (3GPP) divides kSSB into two parts: normal kSSB and abnormal kSSB. Among them, in FR1, the normal kSSB is 0 to 23; in FR2, the normal kSSB is 0 to 11.

[0049] It can be understood that in FR1, if kSSB>23, or in FR2, if kSSB>11, they are all abnormal kSSBs, indicating that the SSB does not have Type 0 common search space (CSS). That is, the current SSB is not associated with SIB1. However, the role of abnormal kSSB is not limited to this. In order to allow the UE to find the CD-SSB quickly, the abnormal kSSB can also be used as an index, combined with the RMSI PDCCH configuration (Config) to indicate the GSCN of the next SSB. That is, the abnormal kSSB can be used as an index, combined with the MIB's PDCCH Config SIB1 to indirectly indicate the GSCN of the next SSB.

[0050] In FR1, the correspondence between kSSB indicating the GSCN of the next SSB can be shown in Table 1 below:

[0051] Table 1

[0052] In FR2, k SSB The corresponding relationship of the GSCN indicating the next SSB can be shown in Table 2 below:

[0053] Table 2

[0054] When in FR1, k SSB =31, or in FR2, k SSB =15, the UE may assume that there is no CD-SSB within a certain GSCN range. Furthermore, the GSCN range may be [N_Reference_GSCN–N_start_GSCN, N_Reference_GSCN+N_end_GSCN]. Wherein, N_start_GSCN may correspond to the upper four bits of PDCCH Config SIB1, and N_end_GSCN may correspond to the lower four bits of PDCCH Config SIB1.

[0055] 2. Type 0 PDCCH common search space set (CSS set)

[0056] The Type 0 PDCCH CSS set can be used to monitor SIB1 system messages, corresponding to downlink control information (DCI) scrambled with the system information-radio network temporary identifier (SI-RNTI) in the primary cell of the Master Cell Group (MCG), configured by IE: PDCCH-ConfigSIB1 in the signaling MIB or by IE: SerachSpaceZero in the signaling PDCCH-ConfigCommon, or by IE: SearchSpaceZero or SearchSpaceSIB1 in the signaling PDCCH-ConfigCommon. The control channel element (CCE) aggregation level supported by the Type 0 PDCCH CSS set and the number of PDCCH candidates in each CCE aggregation level are shown in Table 3 below.

[0057] Table 3

[0058] 3. SSB and CORESET 0

[0059] There are three SSB and CORESET 0 multiplexing patterns: Pattern 1 is time division multiplexing, while Patterns 2 and 3 are frequency division multiplexing. As shown in Figure 2, in Pattern 1, the frequency domain of CORESET 0 includes SSB. In Patterns 2 and 3, CORESET 0 and SSB are in the same system frame. Specifically, the difference between Pattern 2 and Pattern 3 is that in the time domain, CORESET 0 in Pattern 2 is slightly ahead of SSB.

[0060] After the UE decodes the SSB, it can know the specific time-frequency resource location, so that it can blindly detect the scheduling information of SIB1 at the time-frequency resource location.

[0061] 4. SIB1

[0062] After detecting the PBCH, the UE has completed downlink synchronization. Before performing uplink synchronization, the UE needs to further receive SIB1 to obtain configuration information related to uplink synchronization.

[0063] SIB1 is transmitted in PDSCH and scheduled through PDCCH, and the resource allocation range of PDSCH is within the frequency range of the initial bandwidth part (BandWidth Part, BWP).

[0064] The DCI information for scheduling SIB1 is carried in CORESET 0. The PDCCH time-frequency domain resource allocation for SIB1 can include the following three cases:

[0065] The PDCCH of SIB1 is mapped in the CCS of type 0 PDCCH;

[0066] In the frequency domain, the CSS of type 0 PDCCH is mapped in CORESET 0, and the frequency range of CORESET 0 is exactly the same as the initial BWP;

[0067] The lower 4 bits of the signaling PDCCH-ConfigSIB1 carried in the PBCH indicate the configuration of type 0 PDCCH CSS, and the upper 4 bits indicate the configuration of CORESET 0.

[0068] The PDSCH time-frequency domain resource allocation of SIB1 can include the following two cases:

[0069] Conventional PDSCH uses the Time Domain Resource Allocation (TDRA) table configured by RRC, and the PDCCH indicates the index in the table for time domain resource allocation. However, since the RRC connection has not been established when the UE receives the SIB1 PDSCH, a default TDRA needs to be defined;

[0070] The three multiplexing styles of CORESET 0 and SSB correspond to three default TDRA tables respectively. In the frequency domain, SIB1 performs frequency domain resource allocation within the initial access bandwidth and uses resource allocation type 1.

[0071] 5. Location of CORESET 0

[0072] During the NR downlink synchronization process, the UE first blindly detects the SSB, then finds the corresponding CORESET 0 based on the SSB, and then blindly detects the PDCCH within CORESET 0 to obtain the DCI information and thus find the PDSCH carrying SIB1. Specifically, the UE can find the corresponding CORESET 0 by using the offset of the SSB and the frequency lower boundary of CORESET 0 after the resource block (RB) is aligned as indicated by the MIB.

[0073] Since subcarrier 0 of SSB is not necessarily aligned with the position of subcarrier 0 of RB, kSSB (k_SSB) can be defined as the distance between the two, in units of subcarriers, and the subcarrier spacing depends on the subcarrier spacing of SSB. The position N_CRB^SSB of the resource block where the CD-SSB is located in the frequency domain is indicated by the offsetToPointA parameter in SIB1. Among them, the offsetToPointA parameter can be the frequency offset between the reference point A and the lowest subcarrier of the common resource block (CRB) that overlaps with the initial cell selection SSB.

[0074] The embodiments of the present application provide a downlink signal or downlink channel detection method, a downlink signal or downlink channel sending method, an apparatus, a UE, a network-side device, a medium, and a computer program product. The UE can determine the type 0 PDCCH of a cell that supports on-demand request for downlink signal or downlink channel adjustment through the first configuration information and at least one of the SSBs of the cell, thereby obtaining the scheduling information of the SIB through the type 0 PDCCH of the cell.

[0075] Below, in conjunction with the accompanying drawings, the downlink signal or downlink channel detection method, downlink signal or downlink channel sending method, device, UE, network-side equipment, medium and computer program product provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0076] FIG3 shows a flow chart of a downlink signal or downlink channel detection method provided in an embodiment of the present application. As shown in FIG3 , the downlink signal or downlink channel detection method may include the following steps 201 and 202 .

[0077] Step 201: The UE obtains first information, where the first information includes at least one of the following: first configuration information, and an SSB of a first cell.

[0078] Step 202: The UE determines a type 0 PDCCH of a first cell based on the first information, where the first cell is a cell that supports on-demand request for downlink signal or downlink channel adjustment.

[0079] In some embodiments of the present application, the above-mentioned downlink signal or downlink channel adjustment may include at least one of the following: SIB1 transmission, SIB1 adjustment, SSB transmission, and SSB adjustment.

[0080] In some embodiments of the present application, the above-mentioned SIB1 transmission may indicate that the first cell switches from a state of not transmitting SIB1 to a state of transmitting SIB1.

[0081] In some embodiments of the present application, the above-mentioned SSB transmission may indicate that the first cell switches from a state of not transmitting SSB to a state of transmitting SSB.

[0082] In some embodiments of the present application, the above-mentioned SIB1 adjustment may include but is not limited to: adjustment of the SIB1 sending period.

[0083] In some embodiments of the present application, the above-mentioned SSB adjustment may include but is not limited to: adjustment of the SSB transmission period and adjustment of the SSB beam.

[0084] In some embodiments of the present application, the above-mentioned first information may be information sent by a network-side device.

[0085] In some embodiments of the present application, the first configuration information may be configuration information of a wake-up signal (Wake-Up Signal) configuration associated with the first cell.

[0086] In some embodiments of the present application, the first configuration information may be carried by the SIB of the first cell, or carried by the SIB of cell A, or carried by the SIB of a normal cell.

[0087] It should be noted that both cell A and normal cell can indicate cells that normally request downlink signal or downlink channel adjustment. That is, both cell A and normal cell can normally send SIB1 and SSB. The two can be interchangeable.

[0088] In some embodiments of the present application, the cell supporting on-demand request for downlink signal or downlink channel adjustment may be referred to as an NES cell.

[0089] It is understandable that the NES cell can save energy by not actively sending SIB1. After being triggered by the target signal, it can adjust the downlink signal or downlink channel, that is, send SIB1.

[0090] In some embodiments of the present application, the UE may determine the location of the Type 0 PDCCH of the NES cell according to the above-mentioned first information, thereby determining the Type 0 PDCCH of the NES cell.

[0091] In some embodiments of the present application, the UE determining the type 0 PDCCH of the first cell based on the first information may include: the UE determining the type 0 PDCCH of the first cell based on the first configuration information and the SSB of the first cell, the UE determining the type 0 PDCCH of the first cell based on the first configuration information, and the UE determining the type 0 PDCCH of the first cell based on the SSB of the first cell.

[0092] In some embodiments of the present application, when the UE determines the Type 0 PDCCH of the first cell based on the SSB of the first cell, if the value of kSSB in the MIB carried by the SSB of the first cell falls within the range of CD-SSB, the UE can directly determine the Type 0 PDCCH of the first cell based on the SSB of the first cell. For example, the legacy UE can confirm the first cell through WUS configuration or cell A indication, then the legacy UE will not monitor the SIB1 of the first cell, while the R19 UE will directly determine the Type 0 PDCCH based on the MIB in the SSB, and further receive the SIB1.

[0093] It should be noted that the R19 UE may be a new UE, that is, a UE supporting R19 technology, or a UE supporting network energy saving features, or a UE supporting on-demand request for downlink signals or downlink channel adjustment, or a UE supporting sending uplink target signals.

[0094] In some embodiments of the present application, when the value of kSSB in the MIB carried by the SSB of the first cell belongs to the range of NCD-SSB, the UE can determine the type 0 PDCCH of the first cell based on the SSB of the first cell and the first configuration information; or, when the value of kSSB in the MIB carried by the SSB of the first cell belongs to the range of NCD-SSB, the UE can determine the type 0 PDCCH of the first cell based on the first configuration information.

[0095] In some embodiments of the present application, for a detailed description of the UE determining the Type 0 PDCCH of the first cell based on the first configuration information and the SSB of the first cell and the UE determining the Type 0 PDCCH of the first cell based on the first configuration information, refer to the relevant description of steps 202a to 202b below. To avoid repetition, they are not described here.

[0096] In some embodiments of the present application, the first configuration information may include at least one of the following:

[0097] a first cell identifier (ID) or a cell ID list or a cell group ID;

[0098] SSB subcarrier offset ssb-SubcarrierOffset of the first cell;

[0099] Configuration information of CORESET 0 and SS 0 of the first cell, where the configuration information of CORESET 0 and SS 0 may include at least PDCCH-ConfigSIB1;

[0100] Related information of the SSB of the first cell;

[0101] The frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the first cell;

[0102] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell where the UE is currently camped;

[0103] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the UE's current serving cell;

[0104] a frequency domain offset between a frequency domain lower boundary of a frequency domain position of CORESET 0 of a first cell and a reference point A of a second cell, where the second cell is a cell for which the UE receives the first configuration information;

[0105] The frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the target common reference point A, where the target common reference point A is a reference point A configured by the network or agreed upon by the protocol;

[0106] An offset of the first cell relative to the reference point A, where the offset relative to the reference point A may include at least offsetToPointA;

[0107] The state of the first cell includes a state of supporting on-demand request for downlink signal or downlink channel adjustment and a state of normal request for downlink signal or downlink channel adjustment;

[0108] Request relevant configuration information of the downlink signal of the first cell or the target signal of downlink channel adjustment.

[0109] In some embodiments of the present application, the first cell ID or cell ID list or cell group ID associated with the first configuration information may indicate the cell ID that supports on-demand request for downlink signal or downlink channel adjustment, so that the UE can determine the first cell that supports on-demand request for downlink signal or downlink channel adjustment based on the cell ID of the cell.

[0110] In some embodiments of the present application, the second cell may be a cell that normally requests downlink signal or downlink channel adjustment. In other words, the second cell may normally send SIBs and SSBs without the need for target signal triggering.

[0111] For example, as shown in FIG4 , the second cell is a cell that normally requests a downlink signal or downlink channel adjustment, and the second cell normally sends SIB1; the first cell is a cell that supports on-demand request for a downlink signal or downlink channel adjustment, and the first cell sends SIB1 only after receiving the target signal.

[0112] In some embodiments of the present application, the ssb-SubcarrierOffset of the above-mentioned first cell may include: the number of subcarriers offset between subcarrier 0 of the SSB of the first cell and subcarrier 0 of the target CRB.

[0113] Among them, the above-mentioned target CRB can be the CRB that overlaps with the lowermost part of the SSB and has the smallest frequency.

[0114] In some embodiments of the present application, the SSB subcarrier offset ssb-SubcarrierOffset of the above-mentioned first cell may also be referred to as kSSB, or kssb, or kssb.

[0115] It should be noted that ssb-SubcarrierOffset, kSSB, kssb and kssb in this application can all represent SSB subcarrier offset, and the four can be interchangeable.

[0116] In some embodiments of the present application, the PDCCH-ConfigSIB1 of the first cell may be used to indicate at least one of the following:

[0117] The RB offset of the frequency domain lower boundary of the frequency domain position of subcarrier 0 and CORESET 0 of the SSB of the first cell;

[0118] CORESET 0 multiplexing style;

[0119] The number of symbols in CORESET 0;

[0120] The number of RBs in CORESET 0;

[0121] System Frame Number (SFN) of Type 0 PDCCH;

[0122] Type 0 PDCCH slot index;

[0123] Starting symbol of Type 0 PDCCH.

[0124] In some embodiments of the present application, the SSB-related information of the first cell may include at least one of the following:

[0125] GSCN of the SSB of the first cell;

[0126] The SSB frequency of the first cell;

[0127] Whether the information field indicated by the MIB of the first cell is valid.

[0128] In some embodiments of the present application, the information field indicated by the MIB of the first cell may include at least one of the following:

[0129] ssb-SubcarrierOffset of the first cell;

[0130] PDCCH-ConfigSIB1 information of the first cell;

[0131] Cell barring information of the first cell.

[0132] In some embodiments of the present application, when the first information includes first configuration information, and the first configuration information includes relevant information of the SSB of the first cell, the network side device can directly indicate whether the information field indicated by the MIB of the first cell is valid through the relevant information of the SSB of the first cell in the first configuration information, so that the UE can determine the type 0 PDCCH of the first cell based on the valid information field indicated by the network side device.

[0133] In some embodiments of the present application, when the first configuration information includes the kSSB of the first cell and the PDCCH-ConfigSIB1 of the first cell, the R19 UE can determine whether the kSSB and PDCCH-ConfigSIB1 indicated by the SSB of the first cell are valid by whether the first configuration information associated with the first cell contains the value of kSSB and the value of PDCCH-ConfigSIB1.

[0134] In some embodiments of the present application, if the first configuration information includes the value of kSSB and the value of PDCCH-ConfigSIB1 of the first cell, the R19 UE may use the value of kSSB and PDCCH-ConfigSIB1 in the first configuration information to determine the position of the type 0 PDCCH. If the first configuration information does not include the value of kSSB or the value of PDCCH-ConfigSIB1 of the first cell, the R19 UE may determine the position of the type 0 PDCCH of the first cell based on the value of kSSB in the MIB carried in the SSB of the first cell and the value of PDCCH-ConfigSIB1.

[0135] In some embodiments of the present application, when the positional relationship between the SSB of the first cell and CORESET 0 is specified in advance, the R19 UE can determine whether the kSSB of the first cell is valid by whether the first configuration information contains the value of the kSSB of the first cell.

[0136] In some embodiments of the present application, if the first configuration information includes the kSSB value of the first cell, the R19 UE can directly use the kSSB value in the first configuration information to determine the position of the type 0 PDCCH; if the first configuration information does not include the kSSB value of the first cell, the R19 UE can use the kSSB value in the MIB carried by the SSB of the first cell to determine the position of the type 0 PDCCH of the first cell.

[0137] In some embodiments of the present application, the multiple parameters required for the UE to confirm the location of the type 0 PDCCH may include at least one of kssb, PDCCH-ConfigSIB1, and offsetToPointA, and the multiple parameters may be directly carried by the first configuration information. If the first configuration information does not carry the multiple parameters, the UE may directly determine the location of the type 0 PDCCH according to the values ​​indicated in the MIB of the first cell.

[0138] In some embodiments of the present application, when the kSSB indication of the first cell is a specified value or a predetermined value, such as the kSSB indication of the first cell is FR1=30 (i.e., in the FR1 frequency band, the kssb value is 30), FR2=14 (in the FR2 frequency band, the kssb value is 14), or the kSSB indication of the first cell is a reverved value, the R19 UE can determine whether the kSSB of the first cell is valid by whether the first configuration information contains the value of the kSSB of the first cell.

[0139] In some embodiments of the present application, if the first configuration information includes the kSSB value of the first cell, the R19 UE can use the kSSB value in the first configuration information to determine the location of the type 0 PDCCH, or if the first configuration information configures kSSB for a physical cell identifier (PCI), the UE can determine the type 0 PDCCH corresponding to the cell of this PCI according to the kSSB in the first configuration information; if the first configuration information does not include the kSSB value of the first cell, the R19 UE can use the kSSB value in the MIB carried by the SSB of the first cell to determine the location of the type 0 PDCCH of the first cell.

[0140] In some embodiments of the present application, the frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the above-mentioned first cell and the reference point A of the first cell may include at least one of the following: an offset of RB granularity and an offset of subcarrier granularity.

[0141] In some embodiments of the present application, the frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the above-mentioned first cell and the reference reference point A of the cell where the UE is currently stationed may include at least one of the following: an offset of RB granularity and an offset of subcarrier granularity.

[0142] In some embodiments of the present application, the frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the above-mentioned first cell and the reference reference point A of the UE's current serving cell may include at least one of the following: an offset of RB granularity and an offset of subcarrier granularity.

[0143] In some embodiments of the present application, the frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the above-mentioned first cell and the reference point A of the second cell may include at least one of the following: an offset of RB granularity and an offset of subcarrier granularity.

[0144] In some embodiments of the present application, the frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the above-mentioned first cell and the target common reference point A may include at least one of the following: an offset of RB granularity, an offset of subcarrier granularity, and the target common reference point A is a reference point A configured on the network side or agreed upon by the protocol.

[0145] In some embodiments of the present application, the offsetToPointA of the above-mentioned first cell may indicate the frequency offset between the reference point A and the lowest subcarrier of the lowest resource block, and the lowest resource block overlaps with the SSB used by the UE for initial cell selection.

[0146] In some embodiments of the present application, the UE does not need to know the offsetToPointA of the first cell to determine the location of the type 0 PDCCH. After receiving the type 0 PDCCH and decoding SIB1, the UE refers to the offsetToPointA in SIB1. Therefore, the first configuration information may not carry offsetToPointA.

[0147] In some embodiments of the present application, the above-mentioned state of supporting on-demand request for downlink signal or downlink channel adjustment may indicate that the cell does not actively request downlink signal or downlink channel adjustment, and it may trigger a downlink signal or downlink channel adjustment request through a target signal.

[0148] Exemplarily, the UE triggering a downlink signal or a downlink channel adjustment request through a target signal may include the UE triggering the network side device to send SIB1 through a WUS.

[0149] In some embodiments of the present application, the state of normally requesting downlink signal or downlink channel adjustment may indicate that the cell normally requests downlink signal or downlink channel adjustment on demand. In other words, the state of the cell normally requesting downlink signal or downlink channel adjustment may indicate that the cell normally sends SIBs and SSBs.

[0150] In some embodiments of the present application, the configuration information related to the target signal for requesting adjustment of the downlink signal or downlink channel of the first cell includes at least one of the following:

[0151] Time-frequency resource allocation;

[0152] Power configuration;

[0153] Synchronize configuration.

[0154] In some embodiments of the present application, the target signal may be used to trigger adjustment of a downlink signal or downlink channel of the first cell.

[0155] The downlink signal or downlink channel detection method provided in the embodiment of the present application can enable the UE to determine the type 0 PDCCH of the cell that supports on-demand request for downlink signal or downlink channel adjustment through the first configuration information and at least one of the SSBs of the first cell, thereby obtaining the SIB scheduling information through the type 0 PDCCH of the cell.

[0156] In some embodiments of the present application, the above-mentioned step 202 may include any one of the following steps 202a, 202b, 202c and 202d.

[0157] Step 202a: In the case where the first information includes the first configuration information, if the first configuration information includes the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell.

[0158] In some embodiments of the present application, the offset of the first cell relative to the reference point A may not be configured, that is, the offsetToPointA of the first cell may not be configured. In other words, the UE may determine the type 0 PDCCH of the first cell based on the PDCCH-ConfigSIB1 of the first cell and the ssb-SubcarrierOffset of the first cell.

[0159] In some embodiments of the present application, if the value of kSSB in the SSB of the first cell is in the range of NCD-SSB, that is, in the FR1 frequency band, the range of kssb is 24 to 29, and in the FR2 frequency band, the range value of kssb is 12 to 13, then the value of kSSB cannot represent the offset between RB0 and SSB subcarrier 0, and the value of PDCCH-ConfigSIB1 cannot represent the true configuration of CORESET 0 and SS0, and even the network side does not directly indicate the value of PDCCH-ConfigSIB1 (or, there is no PDCCH-ConfigSIB1 domain in the MIB). At this time, the true kSSB and PDCCH-ConfigSIB1 need to be obtained through other means.

[0160] In some embodiments of the present application, when the first information includes first configuration information, the network side device can configure the position of type 0 PDCCH and the position of the SSB of the first cell to the UE through the first configuration information.

[0161] It is understandable that the network-side device can indicate the location of the type 0 PDCCH through PDCCH-ConfigSIB1, and the location of the SSB of the first cell can be determined through kSSB and offsetToPointA. That is, the first configuration information may include the PDCCH-ConfigSIB1 of the first cell, the offsetToPointA of the first cell, and the ssb-SubcarrierOffset of the first cell. The UE can determine the type 0 PDCCH of the first cell based on at least one of the PDCCH-ConfigSIB1 of the first cell, the offsetToPointA of the first cell, and the ssb-SubcarrierOffset of the first cell.

[0162] It can be understood that the first configuration information can configure the PDCCH-ConfigSIB1 of the first cell and the ssb-SubcarrierOffset of the first cell, and the UE can directly determine the Type 0 PDCCH based on the PDCCH-ConfigSIB1 of the first cell and the ssb-SubcarrierOffset of the first cell in the first configuration information.

[0163] It can be understood that, for R19 UE, the value of PDCCH-ConfigSIB1 can indicate the configuration of CORESET 0 and SS0.

[0164] Step 202b: In the case where the first information includes the first configuration information, if the first configuration information includes the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell, and the first offset information.

[0165] The first offset information is agreed upon by the protocol or configured by the network side device, and the first offset information is the offset information between the SSB of the first cell and CORESET 0. The PDCCH-ConfigSIB1 field in the configuration information of CORESET 0 and SS 0 does not need to be configured with the offset between the lower boundary of the SSB and the lower boundary of OCRESET0, and the offset between the lower boundary of the SSB and the lower boundary of OCRESET0 can be determined by the first offset.

[0166] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell based on the first configuration information, the relative position relationship between the SSB and CORESET 0 of the first cell can be specified in advance through protocol agreement or network side device configuration, without configuring the relative relationship between the SSB and CORESET0 in the first configuration information, and PDCCH-ConfigSIB1, offsetToPointA and kssb are configured to the UE through the first configuration information.

[0167] In some embodiments of the present application, although the relative relationship between the first cell SSB and CORESET 0 may not be configured through the first configuration information, information such as the frequency domain length of CORESET 0 still needs to be determined based on PDCCH-ConfigSIB1. Therefore, PDCCH-ConfigSIB1 can be configured to the UE through the first configuration information.

[0168] In some embodiments of the present application, the first offset information indicates at least one of the following:

[0169] The frequency domain lower boundary of CORESET 0 is aligned to the lower boundary of subcarrier 0 of the SSB of the first cell;

[0170] The frequency domain lower boundary of CORESET 0 and the lower boundary of subcarrier 0 of the SSB of the first cell are fixedly offset by X RBs, where X is not equal to 0.

[0171] The frequency domain lower boundary of CORESET 0 is aligned with the frequency domain upper boundary of the SSB of the first cell;

[0172] The frequency domain upper boundary of CORESET 0 is aligned with the frequency domain lower boundary of the SSB of the first cell.

[0173] In some embodiments of the present application, when X is a positive value, the frequency domain lower boundary of CORESET 0 is X RBs lower than the lower boundary of subcarrier 0 of the SSB of the first cell.

[0174] In some embodiments of the present application, when X is a negative value, the frequency domain lower boundary of CORESET 0 is X RBs higher than the lower boundary of subcarrier 0 of the SSB of the first cell.

[0175] In some embodiments of the present application, when X is a positive value, the subcarrier spacing (SCS) may be the SCS of CORESET 0, which may be obtained through the common subcarrier spacing (subCarrierSpacingCommon) in the MIB of the first cell.

[0176] In this way, when the first configuration information includes the PDCCH-ConfigSIB1 of the first cell, the offsetToPointA of the first cell and the ssb-SubcarrierOffset of the first cell, the UE can determine the type 0 PDCCH of the first cell according to the offset information between the SSB and CORESET 0 of the first cell agreed upon in the protocol or configured by the network side device, and at least one of the PDCCH-ConfigSIB1 of the first cell, the offsetToPointA of the first cell and the ssb-SubcarrierOffset of the first cell in the first configuration information, thereby ensuring that the UE can determine the type 0 PDCCH of the first cell.

[0177] Step 202c. When the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell and the offset of the first cell relative to the reference point A, and does not include the configuration information of CORESET 0 and SS 0 of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the ssb-SubcarrierOffset of the first cell and the offset of the first cell relative to the reference point A, and PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0178] In some embodiments, when the kssb indication in the MIB of the first cell is a specific value, such as 30 in FR1 and 14 in FR2, when the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on the ssb-SubcarrierOffset of the first cell and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0179] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell based on the first configuration information and the SSB of the first cell, if the kSSB indication of the first cell is a reserved value, that is, FR1=30, FR2=14, the UE may consider the PDCCH-ConfigSIB1 of the first cell to be valid. In this case, the network side device may configure the value of kSSB and offsetToPointA to the UE through the first configuration information, and the UE determines the type 0 PDCCH of the first cell based on the value of kSSB and offsetToPointA and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0180] Step 202d. When the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell and does not include the configuration information of CORESET 0 and SS 0 of the first cell, the UE determines the type 0 PDCCH of the first cell based on the ssb-SubcarrierOffset of the first cell and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0181] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell based on the first configuration information and the SSB of the first cell, the network side device may also configure the kSSB of the first cell to the UE through the first configuration information, and the UE may determine the type 0 PDCCH of the first cell based on the kSSB of the first cell and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0182] In some embodiments of the present application, when the first information includes first configuration information, if the first configuration information includes configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell.

[0183] In some embodiments of the present application, when the first information includes first configuration information, if the first configuration information includes configuration information of CORESET 0 and SS 0 of the first cell and ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the configuration information of CORESET 0 and SS 0 of the first cell and ssb-SubcarrierOffset of the first cell.

[0184] In some embodiments of the present application, when the first information includes the first configuration information, if the first configuration information includes the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on the configuration information of CORESET 0 and SS 0 of the first cell, the offset of the first cell relative to the reference point A, and at least one of the ssb-SubcarrierOffset of the first cell, and the first offset information; the first offset information is agreed upon by the protocol or configured by the network side device, and the first offset information is the offset information between the SSB and CORESET 0 of the first cell.

[0185] In some embodiments of the present application, when the first information includes the first configuration information, if the first configuration information includes the configuration information of CORESET 0 and SS 0 of the first cell and the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the configuration information of CORESET 0 and SS 0 of the first cell and the ssb-SubcarrierOffset of the first cell, and the first offset information; the first offset information is agreed upon by the protocol or configured by the network side device, and the first offset information is the offset information between the SSB and CORESET 0 of the first cell.

[0186] In some embodiments of the present application, when the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell and the offset of the first cell relative to the reference point A, and does not include the configuration information of CORESET 0 and SS 0 of the first cell, the UE determines the type 0 PDCCH of the first cell based on at least one of the ssb-SubcarrierOffset of the first cell and the offset of the first cell relative to the reference point A, and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0187] In some embodiments of the present application, when the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell, the UE determines the type 0 PDCCH of the first cell based on the ssb-SubcarrierOffset of the first cell and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0188] In some embodiments of the present application, when the first information includes the first configuration information and the SSB of the first cell, if the first configuration information includes the ssb-SubcarrierOffset of the first cell and does not include the configuration information of CORESET 0 and SS 0 of the first cell, the UE determines the type 0 PDCCH of the first cell based on the ssb-SubcarrierOffset of the first cell and the PDCCH-ConfigSIB1 in the MIB in the SSB of the first cell.

[0189] In this way, the UE can flexibly obtain the ssb-SubcarrierOffset, PDCCH-ConfigSIB1 and offsetToPointA required to determine the type 0 PDCCH of the first cell based on the first configuration information and the SSB of the first cell, thereby ensuring that the UE can determine the type 0 PDCCH of the first cell.

[0190] In some embodiments of the present application, when the above-mentioned first information includes the first configuration information and the SSB of the first cell, the above-mentioned step 202 may further include the following step 202e.

[0191] Step 202e: When the ssb-SubcarrierOffset indicated by the SSB of the first cell is the second value, the UE determines the type 0 PDCCH of the first cell based on the PDCCH-ConfigSIB1 in the MIB of the SSB of the first cell and the ssb-SubcarrierOffset in the first configuration information.

[0192] In some embodiments of the present application, the second value may be agreed upon by a protocol or configured by a network-side device.

[0193] In some embodiments of the present application, the first value and the second value may be the same or different, which is not specifically limited in the embodiments of the present application.

[0194] In some embodiments of the present application, the second value may include: indicating that the ssb-SubcarrierOffset is 30 in FR1, and indicating that the ssb-SubcarrierOffset is 14 in FR2.

[0195] In this way, the UE can determine the type 0 PDCCH of the first cell based on the ssb-SubcarrierOffset in the first configuration information and the PDCCH-ConfigSIB1 in the MIB of the SSB of the first cell when the offset of the first cell relative to the reference point A is not configured in the first configuration information, thereby ensuring that the UE can determine the type 0 PDCCH of the first cell to receive SIB1.

[0196] In some embodiments of the present application, in combination with FIG3 , as shown in FIG5 , after the above step 201 , the downlink signal or downlink channel detection method provided in the embodiment of the present application may further include the following steps 203 and 204 .

[0197] Step 203: The UE sends a target signal to the first cell based on the first information.

[0198] Step 204: The UE receives SIB1 based on the type 0 PDCCH of the first cell.

[0199] In some embodiments of the present application, the target signal may be used to trigger a signal for the first cell to request a downlink signal or downlink channel adjustment.

[0200] In some embodiments of the present application, the UE may trigger the first cell to request a downlink signal or downlink channel adjustment by sending a target signal to the first cell, so that the UE may receive SIB1 based on the type 0 PDCCH of the first cell and obtain the SIB scheduling information.

[0201] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell based on the SSB of the first cell, if the value of kSSB in the MIB carried by the SSB of the first cell belongs to the range of CD-SSB, the UE can directly determine the type 0 PDCCH of the first cell based on the SSB of the first cell, and send a target signal to the first cell, triggering the first cell to request a downlink signal or downlink channel adjustment.

[0202] That is to say, in the MIB carried by the SSB sent by the first cell that is in a state of supporting on-demand request for downlink signals or downlink channel adjustment, if the value of kSSB belongs to the range of CD-SSB, the R19 UE can send a target signal to the first cell to wake up the first cell and trigger the sending of SIB1 of the first cell, on the premise that it determines that the first cell is in a state of supporting on-demand request for downlink signals or downlink channel adjustment.

[0203] In some embodiments of the present application, for a legacy UE, since the kSSB indication of the first cell is CD-SSB, the UE can blindly detect the SIB1 of the first cell. However, in fact, the first cell is in a state of supporting on-demand request for downlink signals or downlink channel adjustment, and the first cell does not send SIB1. Therefore, the legacy UE cannot detect the scheduling information of SIB1 at the position of CORESET 0, and the legacy UE will consider this to be a barred cell.

[0204] In some embodiments of the present application, for an R19 UE, before sending a target signal to the first cell to trigger a downlink signal or downlink channel adjustment of the first cell to receive the SIB1 of the first cell, it is necessary to first detect the scheduling information of the SIB1, that is, the UE needs to first confirm the location of the type 0 PDCCH, that is, the UE needs to determine the kSSB of the first cell and the PDCCH-ConfigSIB1 of the first cell. Since the kSSB value of the first cell falls within the range of CD-SSB and the PDCCH-ConfigSIB1 in the MIB is also valid, the R19 UE can directly determine the location of the type 0 PDCCH according to the legacy behavior.

[0205] In some embodiments of the present application, when the value of kSSB of the first cell belongs to the range of NCD-SSB, the UE can send a target signal to the first cell based on the first information, and the UE can determine the type 0 PDCCH of the first cell through the first configuration information, or the first configuration information and the SSB of the first cell, so that the UE can receive SIB1 based on the type 0 PDCCH of the first cell.

[0206] In some embodiments of the present application, the above step 203 may be performed after step 202, or may be performed simultaneously with step 202. FIG5 merely takes step 203 as an example, which is performed after step 202. The embodiments of the present application are not specifically limited.

[0207] In this way, the UE can send a target signal to the first cell through the first information, triggering the first cell to adjust the downlink signal or downlink channel, so that the UE can obtain the SIB scheduling information according to the type 0 PDCCH of the first cell.

[0208] In some embodiments of the present application, the above step 203 may include the following step 203a.

[0209] Step 203a: When the first condition is met, the UE sends a target signal to the first cell based on the first information.

[0210] The first condition mentioned above includes at least one of the following:

[0211] The SSB indication of the first cell is NCD-SSB;

[0212] The value of ssb-SubcarrierOffset of the first cell in the MIB of the first cell belongs to the first interval;

[0213] The value of ssb-SubcarrierOffset of the first cell in the MIB of the first cell is indicated as a first value;

[0214] A reference signal measurement result of the first cell is greater than or equal to a first threshold;

[0215] A reference signal measurement result of the cell where the UE resides is less than or equal to a second threshold;

[0216] The reference signal measurement result of the second cell is less than or equal to the second threshold;

[0217] The first configuration information includes target signal configuration information requesting adjustment of a downlink signal or downlink channel of the first cell;

[0218] The first cell is in a state of supporting on-demand request for downlink signal or downlink channel adjustment.

[0219] In some embodiments of the present application, the first interval may be a closed interval in the NCD-SSB range.

[0220] In some embodiments of the present application, the first interval may be a closed interval of FR1: 24-29 and FR2: 12-13.

[0221] In some embodiments of the present application, the first value may be a reverved value.

[0222] In some embodiments of the present application, the first value may be FR1:30, FR2:14.

[0223] In some embodiments of the present application, the first threshold value may be agreed upon by a protocol or configured by a network-side device.

[0224] In some embodiments of the present application, the second threshold value may be agreed upon by a protocol or configured by a network-side device.

[0225] In some embodiments of the present application, the first threshold value and the second threshold value may be the same or different, which is not specifically limited in the embodiments of the present application.

[0226] In some embodiments of the present application, when the UE determines that the first cell is in a state of requesting a downlink signal or downlink channel adjustment on demand, the UE can wake up the first cell by sending a target signal to trigger SIB sending of the first cell.

[0227] In this way, when the first condition is met, the UE can send a target signal to the first cell to trigger the first cell to adjust the downlink signal or downlink channel, so that the UE can obtain the SIB scheduling information through the type 0 PDCCH of the cell.

[0228] In some embodiments of the present application, when the first cell meets the second condition, the first cell is in a state of supporting on-demand request for downlink signal or downlink channel adjustment.

[0229] The first cell meeting the second condition includes at least one of the following:

[0230] The target signal configuration includes a target signal configuration corresponding to the first cell;

[0231] The configuration of the target signal indicates a cell ID of the first cell;

[0232] The ssb-SubcarrierOffset indicated by the SSB of the first cell is a first value.

[0233] In some embodiments of the present application, the configuration of the above-mentioned target signal may be a configuration provided to the UE by the network side device through the first cell or the network side device through the second cell.

[0234] In some embodiments of the present application, the configuration of the above-mentioned target signal can be a configuration provided to the UE by the network side device through the first cell or the network side device through the second cell, and can be carried on the SIB of the first cell or the SIB of the second cell.

[0235] In some embodiments of the present application, when the target signal configuration includes the target signal configuration corresponding to the first cell, the UE may consider the first cell as a cell that supports on-demand request for downlink signal or downlink channel adjustment.

[0236] In some embodiments of the present application, the configuration of the target signal indicating the cell ID of the first cell can be understood as: the configuration of the target signal carries the cell ID of the first cell, or the cell ID list of the first cell, or the cell group ID of the first cell.

[0237] In some embodiments of the present application, when the cell ID of the first cell is indicated in the configuration of the target signal, the UE may consider the first cell corresponding to the cell ID as a cell supporting on-demand request for downlink signal or downlink channel adjustment.

[0238] In some embodiments of the present application, the network side device can configure the relevant configurations of all cells that support on-demand request for downlink signals or downlink channel adjustment through the second cell, and the UE can determine whether the first cell is a cell that supports on-demand request for downlink signals or downlink channel adjustment based on the ssb-SubcarrierOffset indicated by the SSB of the first cell being the first value.

[0239] Exemplarily, the first value may be a reserved value.

[0240] Exemplarily, the first value may be 30 in the FR1 frequency band and 14 in the FR2 frequency band.

[0241] It is understandable that the UE can determine whether the cell is in a state of supporting on-demand request for downlink signal or downlink channel adjustment or in a state of normal request for downlink signal or downlink channel adjustment through the change of ssb-SubcarrierOffset.

[0242] In some embodiments of the present application, the UE may not confirm whether the first cell has been triggered by other UEs to request downlink signal or downlink channel adjustment, that is, it may not confirm whether the first cell has started downlink signal or downlink channel adjustment. The UE may only determine whether the cell is a cell that supports on-demand request for downlink signal or downlink channel adjustment.

[0243] In some embodiments of the present application, if the first cell has been triggered by another UE to request a downlink signal or downlink channel adjustment, the UE may send the target signal to the first cell again. In other words, for the UE, this is just an extra step of sending the target signal and will not cause any other impact.

[0244] In some embodiments of the present application, if the first cell is not triggered by other UEs to request downlink signal or downlink channel adjustment, the UE may send a target signal to the first cell once to trigger the first cell to request downlink signal or downlink channel adjustment. In this case, no unnecessary actions are performed on either the network-side device or the UE.

[0245] In this way, since the UE can determine whether the first cell is in a state of supporting on-demand request for downlink signals or downlink channel adjustment based on the configuration of the target signal or the value of ssb-SubcarrierOffset indicated by the SSB of the first cell, it can ensure that the UE can go to the cell in a state of supporting on-demand request for downlink signals or downlink channel adjustment, thereby avoiding waste of resources.

[0246] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell through the first configuration information, as shown in Figure 6, the downlink signal or downlink channel detection method provided in the embodiment of the present application may include the following steps S11 to S16.

[0247] Step S11: The UE obtains the SSB of the first cell and determines that the value of kSSB in the MIB carried by the SSB of the first cell is within the NCD-SSB range.

[0248] Step S12: The second cell provides first configuration information to the UE.

[0249] The first configuration information may include at least one of the following:

[0250] offsetToPointA of the first cell;

[0251] kSSB of the first cell;

[0252] PDCCH-ConfigSIB1 of the first cell;

[0253] Related information of the SSB of the first cell;

[0254] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell where the UE is currently camped;

[0255] The frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell in which the UE currently receives the first configuration information;

[0256] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the UE's current serving cell;

[0257] The offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the target common reference point A.

[0258] In some embodiments of the present application, the target public reference point A may be a reference point A configured on the network side or agreed upon by a protocol.

[0259] In some embodiments of the present application, the UE receives the first configuration information and receives the SSB of the first cell in no particular order, that is, the UE can first receive the first configuration information and then detect the SSB of the first cell, or it can first detect the SSB of the first cell and then receive the first configuration information.

[0260] In some embodiments of the present application, the first configuration information may be provided to the UE by the first cell or by the second cell. The embodiment of the present application only takes the second cell providing the first configuration information to the UE as an example.

[0261] Step S13: The UE sends a target signal to the first cell based on the first information.

[0262] In some embodiments of the present application, since the value of kSSB falls within the range of NCD-SSB, the legacy UE may not process the first configuration information.

[0263] In some embodiments of the present application, the R19 UE may receive the type 0 PDCCH of the first cell based on the kSSB and PDCCH-ConfigSIB1 and offsetToPointA in the first configuration information, while ignoring the value of kSSB indicated by the MIB of the SSB of the first cell and the value of PDCCH-ConfigSIB1.

[0264] Step S14: The first cell sends a type 0 PDCCH to the UE.

[0265] Step S15: The UE monitors the Type 0 PDCCH according to the kSSB and PDCCH-ConfigSIB1 in the first configuration information.

[0266] Step S16: The UE receives SIB1 according to the Type 0 PDCCH.

[0267] In this way, the UE can determine the type 0 PDCCH of the cell that supports on-demand request for downlink signal or downlink channel adjustment through at least one item in the first configuration information, and thus can obtain the SIB scheduling information through the type 0 PDCCH of the cell.

[0268] In some embodiments of the present application, when the UE determines the type 0 PDCCH of the first cell through the first configuration information, taking the first offset information as the offset information for aligning the CORESET 0 lower boundary and the SSB lower boundary of the NES cell specified by the protocol as an example, as shown in Figure 7, the downlink signal or downlink channel detection method provided in the embodiment of the present application may also include the following steps S21 to S26.

[0269] Step S21: The UE obtains the SSB of the first cell and determines that the value of kSSB in the MIB carried by the SSB of the first cell is within the NCD-SSB range.

[0270] Step S22: The second cell provides first configuration information to the UE.

[0271] In some embodiments of the present application, the first configuration information may be provided to the UE by the first cell or by the second cell. The embodiment of the present application only takes the second cell providing the first configuration information to the UE as an example.

[0272] In some embodiments of the present application, the first configuration information may include at least one of the following:

[0273] offsetToPointA of the first cell;

[0274] kssb of the first district;

[0275] PDCCH-ConfigSIB1 of the first cell;

[0276] Related information of the SSB of the first cell;

[0277] The relative offset relationship between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the SSB frequency domain of the first cell;

[0278] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell where the UE is currently camped;

[0279] The frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell in which the UE currently receives the first configuration information;

[0280] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the UE's current serving cell;

[0281] The offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the target common reference point A.

[0282] Step S23: The UE sends a target signal to the first cell based on the first information.

[0283] In some embodiments of the present application, since the value of kSSB belongs to the range of NCD-SSB, the legacy UE can find the position of the next CD-SSB based on the kSSB and PDCCH-ConfigSIB1 of the first cell.

[0284] In some embodiments of the present application, the R19 UE may send a target signal to the first cell upon confirming that the first cell is in a state supporting on-demand request for downlink signal or downlink channel adjustment (for example, the information is obtained through WUS configuration).

[0285] Step S24: The first cell sends a type 0 PDCCH to the UE.

[0286] Step S25: The UE monitors the Type 0 PDCCH according to PDCCH-ConfigSIB1 and offsetToPointA in the first configuration information.

[0287] In some embodiments of the present application, the UE may directly ignore the value of kSSB in the SSB of the first cell, and detect the type 0 PDCCH of the received NES cell according to PDCCH-ConfigSIB1, offsetToPointA and kssb and the first offset information included in the first configuration information.

[0288] Step S26: The UE receives SIB1 according to the type 0 PDCCH.

[0289] In this way, the UE can determine the type 0 PDCCH of the cell that supports on-demand request for downlink signal or downlink channel adjustment through the first configuration information and the predefined relative offset relationship between CORESET 0 and SSB, so that it can obtain the scheduling information of the SIB through the type 0 PDCCH of the cell.

[0290] In some embodiments of the present application, when the value of kSSB of the first cell belongs to the range of NCD-SSB, if the value of kSSB of the first cell is indicated as a reserved value, the UE can send a target signal to the first cell based on the first configuration information and the SSB of the first cell, and the UE can determine the type 0 PDCCH of the first cell through the first configuration information and the SSB of the first cell, so that the UE can receive SIB1 based on the type 0 PDCCH of the first cell.

[0291] In some embodiments of the present application, when the UE determines the type 0PDCCH of the first cell through the first configuration information and the SSB of the first cell, as shown in Figure 8, the downlink signal or downlink channel detection method provided in the embodiment of the present application may also include the following steps S31 to S36.

[0292] Step S31: The UE obtains the SSB of the first cell, and determines that the value of kSSB in the MIB carried by the SSB of the first cell is indicated as a reserved value.

[0293] Step S32: The second cell provides first configuration information to the UE.

[0294] In some embodiments of the present application, the first configuration information may be provided to the UE by the first cell or by the second cell. The embodiment of the present application only takes the second cell providing the first configuration information to the UE as an example.

[0295] In some embodiments of the present application, the first configuration information may include at least one of the following:

[0296] offsetToPointA of the first cell;

[0297] kSSB of the first cell;

[0298] Related information of the SSB of the first cell;

[0299] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell where the UE is currently camped;

[0300] The frequency domain offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the cell in which the UE currently receives the first configuration information;

[0301] The frequency domain offset between the lower frequency domain boundary of the frequency domain position of CORESET 0 of the first cell and the reference point A of the UE's current serving cell;

[0302] The offset between the frequency domain lower boundary of the frequency domain position of CORESET 0 of the first cell and the target common reference point A.

[0303] Step S33: The UE sends a target signal to the first cell based on the first configuration information and the SSB of the first cell.

[0304] In some embodiments of the present application, since the value of kSSB is a reserved value and there is no further indication of the location of the CD-SSB, the legacy UE can only search for the SSB on its own.

[0305] In some embodiments of the present application, for an R19 UE, the UE may determine that the first cell is in a state supporting on-demand request for downlink signal or downlink channel adjustment. At this time, the UE may consider that the PDCCH-ConfigSIB1 in the MIB of the SSB of the first cell is valid, and thus the UE may confirm the location of the Type 0 PDCCH based on the kSSB value and offsetToPointA in the first configuration information and the PDCCH-ConfigSIB1 in the MIB of the SSB of the first cell.

[0306] Step S34: The first cell sends a type 0 PDCCH to the UE.

[0307] Step S35: The UE monitors the Type 0 PDCCH according to the PDCCH-ConfigSIB1 in the MIB of the SSB of the first cell and the kSSB value in the first configuration information.

[0308] Step S36: The UE receives SIB1 according to the Type 0 PDCCH.

[0309] In this way, the UE can determine the type 0 PDCCH of the cell that supports on-demand request for downlink signal or downlink channel adjustment through the first configuration information and the SSB of the first cell, and thus can obtain the SIB scheduling information through the type 0 PDCCH of the cell.

[0310] FIG9 shows a flow chart of a method for sending a downlink signal or a downlink channel provided in an embodiment of the present application. As shown in FIG9 , the method for sending a downlink signal or a downlink channel may include the following step 301 .

[0312] In some embodiments of the present application, the above-mentioned downlink signal or downlink channel adjustment includes at least one of the following: system information block SIB1 transmission, SIB1 adjustment, SSB transmission, and SSB adjustment.

[0313] In some embodiments of the present application, the above-mentioned first configuration information and the SSB of the first cell can be provided to the UE through the same cell, or can be provided to the UE through different cells.

[0314] In some embodiments of the present application, after the above step 301, the downlink signal or downlink channel sending method provided by the embodiment of the present application may further include the following steps 302 and 303.

[0315] Step 302: The network-side device receives a target signal sent by the UE.
