Description

Technical Field

[0001] The present application relates to a wireless communication network, for example, to a resource set configuration, a detection method, a service node, a terminal and a storage medium. Background Art

[0002] The New Radio (NR) system has high configuration flexibility and a larger bandwidth range, and also puts forward higher requirements on the capabilities of the terminal (User Equipment, UE). However, among the various scenarios supported by the NR system, not all scenarios require such high UE capabilities. For example, for scenarios such as smart wearable devices (Wearable), video surveillance (Video Surveillance), and industrial wireless sensors (Industrial Wireless Sensors), the capabilities of the UE can be simplified, such as making the UE have a smaller bandwidth capability and a smaller number of antennas, thereby reducing the production cost and complexity of the UE, and also reducing the energy consumption of the UE during operation. Since the configuration mode of the control resource set (Control-Resource Set, CORESET) is fixed, and the receiving performance of this type of reduced capability terminal (RedCap UE) is weaker than that of the non-simplified capability UE in the NR system, based on the same configuration as the non-simplified capability UE, it is impossible to ensure that the RedCap UE correctly detects the control information of the downlink channel by decoding the control resource set, thereby affecting the initial access process.

[0029] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0030] During the initial access process of the NR system, the terminal first receives the Synchronization Signal Block / Physical Broadcast Channel (SSB or SS / PBCH Block), which includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS) and the Physical Broadcast Channel (PBCH), wherein the Master Information Block (MIB) carried in the PBCH contains the configuration information of the Control Resource Set zero (CORESET0). CORESET0 includes at least one resource sent by a PDCCH, and the PDCCH is used to carry the scheduling information of the System Information Block 1 (SIB1). After receiving the SSB, the terminal obtains the configuration information of CORESET0 by decoding the MIB, and then obtains the scheduling information of SIB1 by decoding the PDCCH in CORESET0. Finally, the corresponding SIB1 information can be decoded to determine the Physical Downlink Shared Channel (PDSCH). For RedCap UE, since its receiving performance is weaker than that of NR UE, during the process of RedCap UE decoding PDCCH in CORESET0, PDCCH may not be correctly detected, which may cause RedCap UE to be unable to complete the initial access process. The method provided in the embodiment of the present application is applicable to the scenario of detecting PDCCH in the control resource set.

[0031] The protocol stipulates that there are three multiplexing patterns for control resource sets and SSBs. For pattern 1, the period of CORESET0 defaults to 20ms and will not change due to changes in the period of SSB. The CORESET0 resources corresponding to different SSBs can use frequency division multiplexing (FDM) in the frequency domain. The physical resource blocks (PRBs) occupied by the CORESET0 corresponding to each SSB in the frequency domain can be configured by the service node. In some scenarios, the CORESET0 corresponding to each SSB occupies 2 time slots and does not share the same time slot with the CORESET0 corresponding to other SSBs.

[0032] In an embodiment of the present application, a resource set configuration method is provided to configure a corresponding control resource set for a target type terminal, thereby improving the flexibility and reliability of the control resource set configuration, enabling the target type terminal to effectively detect the corresponding control resource set and accurately obtain the control information of the downlink channel, thereby completing the initial access process.

[0033] Figure 1 FIG. 1 is a flow chart of a resource set configuration method provided by an embodiment. The method can be applied to a service node. Figure 1 As shown, the method provided in this embodiment includes step 110 and step 120.

[0034] In step 110, at least one control resource set corresponding to a target type terminal is configured within a cycle or a time period.

[0035] In step 120, a physical downlink control channel PDCCH is sent in the control resource set.

[0036] In this embodiment, the target type terminal refers to the RedCap UE, the capabilities of the target type terminal are simplified, and its receiving performance is weaker than that of the non-target type terminal in the NR system (which can be understood as NR UE, or Legacy UE). Based on the same configuration as the non-target type terminal, it cannot be guaranteed that the target type terminal can correctly obtain the control resource set (CORESET) and obtain the control information of the downlink channel. In this embodiment, the service node considers the capabilities of the target type terminal, configures the corresponding control resource set for the target type terminal, and sends the PDCCH through the configured control resource set. The target type terminal can obtain an accurate PDCCH by detecting the corresponding control resource set and decoding, wherein the control resource set corresponding to the target type terminal can be independently configured for the target type terminal, or it can be shared with the non-target type terminal.

[0037] In one embodiment, the control resource set includes at least one of the following: a first control resource set corresponding to at least one first SSB within the period or time period; and at least one second control resource set.

[0038] In this embodiment, the target type terminal control resource set may include a first control resource set corresponding to at least one first SSB in a period or time period, wherein the first SSB refers to the SSB corresponding to the non-target type terminal in the NR system. On the one hand, the first SSB can be used to indicate the corresponding first control resource set for the non-target type terminal, and the first control resource set includes the PDCCH corresponding to the non-target type terminal. On the other hand, the first control resource set indicated by at least one first SSB in a period or time period can also be used by the target type terminal, that is, it can be determined by the target type terminal as its corresponding control resource set.

[0039] Within a cycle or a time period, the number of first SSBs is at least 1. For example, the number of first SSBs is 4, and the index i of the first SSB is 0 or 1 or 2 or 3 respectively. The first control resource set corresponding to all first SSBs or part of the first SSBs (for example, the first SSB with index 0 and index 1) can be configured as the control resource set corresponding to the target type terminal. The target type terminal can accurately detect the PDCCH by detecting such corresponding control resource set.

[0040] In this embodiment, the control resource set corresponding to the target type terminal may also include at least one second control resource set, and the second control resource set refers to a control resource set independently configured for the target type terminal, and the non-target type terminal cannot identify the second control resource set. The second control resource set is a resource other than the first SSB and the first control resource set within the period or time period.

[0041] In one embodiment, it further includes:

[0042] Step 101: Within the period or time period, configure a second SSB corresponding to the target type terminal, and the second SSB is associated with a second control resource set.

[0043] In this embodiment, a second SSB (Additional SSB) is independently configured for the target type terminal. The second SSB is used to indicate the corresponding second control resource set for the target type terminal. The non-target type terminal cannot recognize the second SSB.

[0044] In the case where a second SSB is independently configured for a target type terminal, the control resource set corresponding to the target type terminal can be determined based on a first control resource set corresponding to at least one first SSB within the period or time period, or based on a second control resource set corresponding to the second SSB, or jointly determined based on a first control resource set corresponding to at least one first SSB within the period or time period and a second control resource set corresponding to an independently configured second SSB, and PDCCH can be further transmitted based on the control resource set corresponding to the target type terminal.

[0045] Figure 2 A schematic diagram of determining a control resource set corresponding to a target type terminal when configuring a second SSB is provided in an embodiment. The actual transmission period of the first SSB may be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms, but the terminal does not determine the transmission period of the first SSB during the initial access process. For pattern 1, as shown in FIG. Figure 2 As shown, the default period of the first SSB is 20ms, and the first SSB includes SSB0~SSB3. According to SSB0, the first control resource set (marked with the same horizontal line as SSB0) can be determined, and the first PDSCH (as shown in the black filled area) can be determined according to the first control resource set. The second SSB includes SSB a~SSB d, and the period of the second SSB can be configured to be relatively small, for example, 10ms, so that there are two second SSBs used by target type terminals within 20ms, and the second SSB resources of one of them are the same as the first SSB, and the other second SSB is specially configured for the target type terminal. For non-target type terminals, by detecting the first SSB (SSB0) or the second control resource set, the position of the first control resource set can be accurately determined, and then the remaining minimum system information (Remaining Minimum System Information, RMSI) corresponding to the non-target type terminal can be obtained by decoding the first control resource set, that is, the resources of SIB1. For the target type terminal, the position of the control resource set corresponding to the target type terminal can be obtained by detecting the first SSB or the second SSB, and the second PDSCH can be obtained by decoding (as shown in the bold area within the ellipse); it can also be achieved by merging the detected first control resource set and the second control resource set (as shown by the four black bold arrows).

[0046] In one embodiment, the period of the second SSB is smaller than the period of the first SSB to ensure that within each period of the first SSB, the target type terminal can detect at least one second SSB, thereby determining the second control resource set based on the second SSB, and further accurately detecting the PDCCH.

[0047] In one embodiment, the number of the second SSBs is less than or equal to the number of the first SSBs.

[0048] In this embodiment, the number of second SSBs may be equal to the number of first SSBs, that is, corresponding second SSBs are configured for target type terminals for all SSBs; the number of second SSBs may also be smaller than the number of first SSBs. For example, when time domain resources are insufficient, corresponding second SSBs may be configured for target type terminals for some SSBs.

[0049] In one embodiment, when the number of second SSBs is less than the number of first SSBs, the index of the second SSBs is 0 to N2-1, where N2 is the number of second SSBs.

[0050] For example, the number of first SSBs is N1, the number of second SSBs is N2, N2<N1, in this case, the index of the second SSB is 0 to N2-1.

[0051] In one embodiment, the time domain position of the second control resource set is obtained by adding a set offset value to the time domain position of the first control resource set.

[0052] This embodiment is aimed at pattern 1, that is, the scenario where the period of the first control resource set is 20ms by default, and the time domain position of the second control resource set is the time domain position of the first control resource set by adding a set offset value, and the set offset value is 5ms or 10ms. It should be noted that if the set offset value is small, resulting in a conflict between the first control resource set corresponding to the first SSB in the previous period and the first control resource set corresponding to the first SSB in the current period, the target type terminal needs to select one first control resource set from them as the basis for determining the corresponding control resource set, otherwise, the target type terminal will be unable to accurately obtain the PDCCH due to the degradation of detection performance caused by the first control resource set of the conflicting first SSB during the combined detection process. In some embodiments, the service node should be configured to set the offset value to be greater than a certain value to avoid conflicts between the first control resource sets in different periods.

[0053] In one embodiment, for the target type terminal, the number of repetitions of PDSCH is indicated by the first downlink control information (Downlink Control Information, DCI); or, the number of repetitions of PDSCH is indicated by the second DCI; or, the number of repetitions of PDSCH is the same as the number of first control resource set configurations within the period or time period; or, the number of repetitions of PDSCH is the same as the number of second control resource set configurations within the period or time period; or, the number of repetitions of PDSCH is the same as the sum of the number of first control resource set configurations and the number of second control resource set configurations within the period or time period; or, in the case where the corresponding second SSB is configured for the target type terminal, the number of repetitions of PDSCH is the same as the number of repetitions of the second SSB within the period or time period; or, in the case where the corresponding second SSB is configured for the target type terminal, the number of repetitions of PDSCH is the same as the sum of the number of repetitions of the first SSB and the second SSB within the period or time period.

[0054] In this embodiment, the first DCI is configured for a non-target type terminal, and the reserved bit in the first DCI can be used to indicate the number of repetitions of the PDSCH of the target type terminal; the second DCI is configured for the target type terminal, and can be used to indicate the number of repetitions of the PDSCH of the target type terminal, which cannot be interpreted by the non-target type terminal; the number of repetitions of the PDSCH of the target type terminal may also be the same as the number of the first control resource set configuration within the period or time period; it may also be the same as the sum of the number of the first control resource set configuration within the period or time period and the number of the second control resource set configuration; the PDSCH of the target type terminal The number of repetitions of the SCH may also be the same as the number configured for the second control resource set within the period or time period; if the second SSB is independently configured for the target type terminal, the number of repetitions of the PDSCH of the target type terminal may also be the same as the number of repetitions of the second SSB within the period or time period, wherein the number of repetitions of the second SSB refers to the number of repetitions of the second SSB with the same index; or, the same as the sum of the number of repetitions of the first SSB and the second SSB within the period or time period, wherein the number of repetitions of the first SSB refers to the number of repetitions of the first SSB with the same index, and the number of repetitions of the second SSB refers to the number of repetitions of the second SSB with the same index.

[0055] In one embodiment, the information carried in the first DCI for scheduling non-target type terminals and the information carried in the second DCI for scheduling target type terminals is the same.

[0056] In this embodiment, the first DCI carried by the PDCCH of the first control resource set carries the same information as the second DCI carried by the PDCCH of the second control resource set. In this case, the target type terminal can combine the detection of the PDCCH of the first control resource set and the PDCCH of the second control resource set to obtain the corresponding PDSCH.

[0057] In one embodiment, the number of repetitions used by the target type terminal to detect the corresponding control resource set, that is, the number of combined detections, may be a default value, for example, the number of control resource sets within 20 ms.

[0058] In one embodiment, the PDSCH start time slot of the target type terminal is the same as the time slot where the last control resource set is located when the first control resource set and the second control resource set are detected in combination.

[0059] In one embodiment, when a corresponding second SSB is configured for a target type terminal, the first master information block (MIB) information in the first SSB is consistent with the second MIB information in the second SSB.

[0060] In this embodiment, the resource configuration information of the first control resource set and the second control resource set are consistent, that is, the information carried by the first MIB and the second MIB is consistent. Therefore, when a non-target type terminal directly interprets the second SSB as the first SSB, after decoding the second SSB, the position of the first control resource set can be accurately determined.

[0061] Figure 3 A schematic diagram of determining a control resource set corresponding to a target type terminal when a second SSB is configured is provided for another embodiment. Figure 3 As shown, for non-target type terminals, the position of the first control resource set can only be determined by detecting the first SSB (SSB0), and then the RMSI (that is, SIB1) resources corresponding to the non-target type terminal can be obtained by decoding the first control resource set; while for target type terminals, the position of the control resource set corresponding to the target type terminal can only be obtained by detecting the first SSB or the second SSB, and the second PDSCH can be obtained by decoding the corresponding control resource set (as shown in the bold area within the ellipse).

[0062] In one embodiment, when a corresponding second SSB is configured for a target type terminal, the first SSB and the second SSB satisfy at least one of the following: a sequence used by the synchronization signal in the first SSB is different from a sequence used by the synchronization signal in the second SSB; a relative position between a primary synchronization signal and a secondary synchronization signal in the first SSB is different from a relative position between a primary synchronization signal and a secondary synchronization signal in the second SSB; and a physical broadcast channel in the second SSB is scrambled using a dedicated scrambling code for the target type terminal.

[0063] In this embodiment, the non-target terminal detects the PDCCH in the first control resource set according to the first SSB, and then determines the first RMSI corresponding to the non-target terminal; the target terminal determines whether to continue to detect the first control resource set or the second control resource set according to whether the detected SSB is the first SSB or the second SSB. In order to avoid misdetection of SSB by non-target terminals (interpreting the second SSB as the first SSB), the following centralized method can be used to distinguish the first SSB from the second SSB: 1) The sequence used by the synchronization signal in the first SSB is different from the sequence used by the synchronization signal in the second SSB; 2) The relative position between the primary synchronization signal and the secondary synchronization signal in the first SSB is different from the relative position between the primary synchronization signal and the secondary synchronization signal in the second SSB; 3) The physical broadcast channel in the second SSB is scrambled using the dedicated scrambling code of the target terminal. Improve the flexibility of the control resource set configuration and the reliability of detection of different types of terminals.

[0064] In one embodiment, for the target type terminal, the starting time slot index of PDSCH is: the index of the last time slot in the time slot where the second control resource set is located plus N, where N is an integer greater than or equal to 0; where the value of N is configured by the service node or is a default value.

[0065] In this embodiment, the last time slot where the second control resource set is located refers to: after the target type terminal successfully decodes an indexed SSB (which can be the first SSB or the second SSB), the position of the last time slot in at least one control resource set corresponding to the indexed SSB.

[0066] In one embodiment, the second control resource set is configured through the first SSB; the starting time slot of the second control resource set is determined according to a predetermined rule, or is indicated by the first SSB.

[0067] Figure 4 FIG. 1 is a schematic diagram of configuring a second control resource set provided by an embodiment. Figure 4As shown, the first SSB includes SSB0 to SSB7, and the second SSB is not independently configured for the target type terminal. The starting time slot of the second control resource set is determined according to a predetermined rule or indicated by the first SSB. For example, the first control resource set corresponds to 2 time slots, and the second control resource set is configured in the time slot before or after the 2 time slots. This situation is equivalent to increasing the number of repetitions of the control resource set corresponding to the target type terminal.

[0068] In one embodiment, the time slot where the second control resource set is located includes the time slots within the period or time period, but does not include at least one of the following time slots: the time slot occupied by the first SSB; the time slot occupied by the first SSB and the first control resource set exists in the time slot; the time slot where the first control resource set is located.

[0069] In this embodiment, the time slot where the second control resource set is located is determined according to the following principles: within a cycle or time period, the time slot where the second control resource set is located cannot be the time slot occupied by the first SSB, or cannot be the time slot occupied by the first SSB and where the first control resource set exists, or cannot be the time slot where the first control resource set is located, or cannot be multiple time slots among the above three time slots.

[0070] In one embodiment, preferably, the time slot where the second control resource set is located cannot be occupied by the first SSB and the time slot where the first control resource set exists, and cannot be the time slot where the first control resource set is located, so as to distinguish the first control resource set from the second control resource set.

[0071] In one embodiment, the time slots where the second control resource set is located include time slots within a cycle or time period, and the starting time slot index is the index of the last time slot in the time slots where the first control resource set is located plus G1 time slots, where G1 is greater than or equal to 0.

[0072] In this embodiment, the time slot where the second control resource set is located is determined according to the following principles: within a cycle or time period, the actual time slot of the time slot where the second control resource set is located is the last time slot + G1 time slots in the time slot where the first control resource set is located, wherein the time slot where the first control resource set is located refers to the time slot where all first control resource sets corresponding to all first SSBs are located.

[0073] In one embodiment, the time slots indexed from Offset+i*K(i) to Offset+(i+1)*K(i)-1 in the set of time slots where the second control resource set is located are the time slots where the second control resource set corresponding to the first SSB with index i is located; wherein, in the set of time slots where the second control resource set is located, the indexes of the time slots are numbered starting from 0, and K(i) is the number of time slots occupied by the second control resource set corresponding to the first SSB with index i; Offset is an offset, and the value of the offset is configured by the service node or is a default value.

[0074] For example, in the set of time slots where the second control resource set is located, the time slots where the second control resource set corresponding to the first SSB with an index of 0 (i.e., SSB0) are located are: time slot Offset to time slot Offset+K(1)-1; the time slots where the second control resource set corresponding to the first SSB with an index of 1 (i.e., SSB1) are located are: time slot Offset+K(1) to time slot Offset+2*K(2)-1.

[0075] In one embodiment, it further includes:

[0076] Step 102: configuring a time slot where a second control resource set corresponding to a first SSB with index i is located;

[0077] When the index of the configured time slot exceeds the index range of the time slots in the set of time slots where the second control resource set is located, the second control resource set is not configured for the first SSB with index i.

[0078] In this embodiment, if the time slot index of the time slot where the second control resource set corresponding to the first SSB with index i belongs to the time slot range where the second control resource set belongs, the second control resource set is not configured for the first SSB with index i, that is, the target type terminal cannot determine the second control resource set based on the first SSB with index i, but can only determine the second control resource set based on the first SSB with the corresponding time slot index within the time slot range.

[0079] In one embodiment, the number of time slots occupied by the second control resource set corresponding to the first SSB with index i in the second control resource set is the same as the number of time slots occupied by the first control resource set corresponding to the first SSB with the same index.

[0080] For example, in the second control resource set, the number of time slots occupied by the second control resource set corresponding to the first SSB with an index of 0, that is, SSB0, is the same as the number of time slots occupied by the first control resource set corresponding to SSB0.

[0081] In one embodiment, the method further includes: Step 103: indicating at least one of the following through the first SSB:

[0082] Whether the first SSB is configured with a second control resource set;

[0083] The number of time slots occupied by the second control resource set corresponding to the first SSB;

[0084] The time slot position occupied by the second control resource set corresponding to the first SSB.

[0085] In one embodiment, when the interval (Gap) between the frequency domain resource position of the first SSB and the frequency domain position of the first control resource set is greater than a set value, the frequency domain position of the second control resource set is located between the frequency domain resource position of the first SSB and the frequency domain position of the first control resource set.

[0086] In this embodiment, if the interval between the frequency domain position of the first SSB and the first control resource set is large enough, a second control resource set can be configured between the first SSB and the frequency domain position of the first control resource set to reduce interference between the independently configured second control resource set and the first SSB or the first control resource set.

[0087] In one embodiment, the setting value is determined by at least one of the following: configured by a service node; a default value; or determined according to a subcarrier spacing of the second control resource set.

[0088] For example, each subcarrier spacing corresponds to one or more Gap values. When each subcarrier spacing corresponds to one Gap value, the Gap can be determined directly by the subcarrier spacing; when each subcarrier spacing corresponds to multiple Gap values, the optional set of Gap can be first determined by the subcarrier spacing, and then the specific value of Gap in the optional set can be indicated by specific signaling.

[0089] In one embodiment, the subcarrier spacing of the second control resource set is the same as the subcarrier spacing of the first control resource set.

[0090] In one embodiment, the frequency domain position of the second control resource set is adjacent to the frequency domain position of the first control resource set.

[0091] In this embodiment, adjacent means that the frequency domain position of the second control resource set is connected end to end with the frequency domain position of the first control resource set, or, the second control resource set and the first control resource set both have protection bandwidth in the frequency domain resources, and the frequency domain resources occupied by the protection bandwidth of the second control resource set and the first control resource set are connected end to end.

[0092] In one embodiment, the size of the frequency domain resources occupied by the second control resource set is: the maximum value of the frequency domain resources that can be configured by the second control resource set that is less than or equal to the value of the interval.

[0093] In this embodiment, the frequency domain resources occupied by the second control resource set are less than or equal to the interval between the frequency domain resource position of the first SSB and the frequency domain position of the first control resource set, and its value is configured to be as large as possible so that the target type terminal can more effectively detect the second control resource set.

[0094] In one embodiment, the starting time slot (index) of the second control resource set may be indicated by the first SSB, or may be determined according to a default rule, such as the first time slot after the end of the resources of the first control resource set.

[0095] The time slot in which the second control resource set corresponding to each first SSB is located can be indicated by the first SSB, or can be jointly indicated in combination with the starting time slot index. Each first SSB can correspond to a default number of second control resource sets.

[0096] It should be noted that not every first SSB will have a corresponding second control resource set. For example, for a first SSB with an index, if the time slot where its corresponding second control resource set is located is more than a threshold (far away) away from the first control resource set corresponding to its corresponding first SSB, the first SSB with this index does not correspond to the second control resource set; for another example, the second control resource set is valid within a time window of 20ms starting from the first SSB, and the second control resource set is not configured beyond the time window.

[0097] In one embodiment, symbols corresponding to the second control resource set are located in the time slot where the first control resource set is located.

[0098] For example, some symbols are configured in two time slots where the first control resource set is located, for sending the second control resource set.

[0099] Figure 5 FIG. 1 is a schematic diagram of a symbol for configuring a second control resource set provided by an embodiment. Figure 5 As shown, in this embodiment, the second control resource set can be configured in an area outside the symbols occupied by the first control resource set. Figure 5The symbol distribution of two time slots is shown in the figure. The Time Domain Resource Allocation (TDRA) index is used to indicate a resource allocation scheme for PDSCH, which can be indicated by the DCI in the PDCCH in the control resource set; the Demodulation Reference Signal (DMRS) Type A position (DMRS-TypeA-Position) indicates the symbol position of the first DMRS (Front DMRS) in the TypeA PDSCH, which can be indicated by the MIB in the SSB; S0, S1, ... are the indexes of the symbols. The resource allocation scheme for Type A PDSCH can be determined by combining the TDRA index and DMRS-TypeA-Position.

[0100] In this embodiment, in this embodiment, the first control resource set configuration information exists in the first SSB, occupies 8 bits, and can be represented as PDCCH-configSIB1. By reusing the 8 bits of PDCCH-configSIB1, a region of a second control resource set can be mapped within 2 time slots for the target type terminal. The time domain region corresponding to the first control resource set does not overlap with the time domain region corresponding to the second control resource set; the time domain region of the PDSCH associated with the first control resource set does not overlap with the time domain region corresponding to the second control resource set, which can be achieved through scheduling of the service node.

[0101] In this embodiment, the reserved bits in the second MIB are used to independently configure the second control resource set for the target type terminal. For example, the default number of symbols and PRBs occupied by the second control resource set are configured to be consistent with the first control resource set, and the second MIB only needs to indicate the starting symbol of the second control resource set.

[0102] In one embodiment, the symbol corresponding to the second control resource set is indicated by the second control resource set configuration information in the first SSB;

[0103] The second control resource set configuration information in the first SSB is also used to indicate at least one of the following: whether the second control resource set is configured; starting symbol index information of at least one second control resource set; and when the number of time slots where the first control resource set is located is greater than 1, indicating the time slot where the second control resource set is located.

[0104] In this embodiment, the symbol corresponding to the second control resource set is indicated by the second control resource set configuration information (PDCCH-configSIB2) in the first SSB. The second control resource set configuration information can also be used to indicate whether the second control resource set is used for the target type terminal, indicate the index of the starting symbol of at least one second control resource set, indicate the time slot where the second control resource set is located, etc.

[0105] In one embodiment, when the number of symbols occupied by the first control resource set is 1, the starting symbol index of the second control resource set is one of the following: the symbol index occupied by the first control resource set plus 1; the symbol index occupied by the first control resource set plus 2.

[0106] In one embodiment, the second control resource set occupies 1 symbol.

[0107] In one embodiment, the starting symbol index of the second control resource set is: the number of symbols in the time slot minus the product of n and the number of symbols occupied by the second control resource set, minus an offset value; wherein the value of n is an integer greater than or equal to 1, and the value of the offset value is configured by the service node or is a default value.

Therefore, there can be a maximum of 3 reserved bits in the PBCH payload.

[0113] When the maximum number of SSBs supported by the NR system in a 20ms period is 64, the physical layer 8-bit information of the PBCH is occupied, so there can be at most 1 reserved bit in the PBCH payload. The maximum value of the number of SSBs (i.e., the sum of the number of SSBs with different indexes) can be selected from {4, 8, 64}.

[0114] When the target type terminal is supported in the NR system, up to 3 reserved bits in the PBCH of the first SSB can be used to indicate the corresponding control resource set configured for the target type terminal.

[0115] In one embodiment, the reserved bit in the PBCH payload may indicate at least one of the following:

[0116] Whether to configure a second control resource set for a target type terminal;

[0117] Whether to configure a second control resource set for a target type terminal on an adjacent symbol after a first control resource set configured for a non-target type terminal.
