In this way, when the first type of terminal and the second type of terminal coexist in the network, the first type of terminal can still obtain CORESET0 according to the configuration information, and then can correctly access the network, thereby achieving the premise of not affecting the access performance of the second type of terminal to the network, and also ensuring that the first type of terminal can smoothly access the network according to the configuration information.

Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information acquisition and configuration method, device, terminal, base station and storage medium. Background Art

[0002] In the New Radio (NR) system, existing conventional terminals (e.g., mobile phones, etc.) need to first receive the synchronization signal / physical broadcast channel block (Synchronization Signal / Physical Broadcast CHannel Block, SSB) during the initial access process, where SSB is used to carry the synchronization signal, physical broadcast channel (PBCH) and the corresponding demodulation reference signal (DMRS) and other access-related signal channel time-frequency domain resources. The Master Information Block (MIB) carried in the PBCH contains the reception configuration information of the control resource set zero (CORESET0). CORESET0 is used to carry the Type 0 physical downlink control channel (PDCCH), and further, it can carry the reception configuration information of the system information block 1 (SIB1). After receiving the SSB, the existing conventional terminal can obtain the corresponding CORESET0 configuration information according to the indication information in the MIB, for example, the time domain position of CORESET0 and the size of the resources occupied.

[0003] However, compared with conventional terminals, low-capability terminal devices such as smart wearable devices and industrial sensors have smaller bandwidth capabilities, fewer antennas, etc. After receiving SSB, due to the bandwidth configuration of CORESET0 exceeding the bandwidth range of such low-capability terminal devices, or the multiplexing method of CORESET0 and SSB is not supported by such low-capability terminal devices, such low-capability terminal devices cannot further receive CORESET0 and thus cannot access the network, or such low-capability terminal devices can access the network but cannot coexist with existing terminal devices in the network.

[0037] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0038] In addition, in the embodiments of the present application, words such as "optionally" or "exemplarily" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "optionally" or "exemplarily" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "optionally" or "exemplarily" is intended to present related concepts in a specific way. Moreover, the "first" and "second" involved in the embodiments of the present application are only used to distinguish different concepts, messages, etc., and are not used to limit the order.

[0039] In an embodiment of the present application, terminals such as smart wearable devices and industrial sensors whose bandwidth capabilities are smaller than those of existing conventional terminals, such as terminals whose maximum bandwidth supports 10 MHz, 20 MHz or 40 MHz in frequency range 1 (ie, FR1) and 50 MHz or 100 MHz in frequency range 2 (ie, FR2), and terminals that cannot support all configurations of the existing CORESET0 are collectively referred to as first type terminals, and terminals in the conventional sense, such as terminals defined in Release 15 and Release 16, such as mobile phones, are collectively referred to as second type terminals.

[0040] In the NR network, the second type of terminal obtains the corresponding CORESET0 configuration information and search space 0 configuration information according to the PDCCH configuration signaling corresponding to SIB1 in the MIB. A set of tables are defined in the prior art, some of which are shown in Table 1, which are used to indicate the CORESET0 configuration information. The specific indication method is: 4 bits of information are used to indicate indexes 0 to 15, and each index indicates 4 contents, which are the multiplexing pattern between SSB and CORESET0, the number of resource blocks (RB) of CORESET0 Number of symbols in CORESET0 The frequency domain offset between CORESET0 and SSB is, where Figure 1 As shown, a multiplexing pattern of 1 indicates that CORESET0 and SSB occupy different symbols in the time domain, and CORESET0 includes SSB in the frequency domain. A multiplexing pattern of 2 indicates that CORESET0 and SSB occupy different resources in the frequency domain and SSB occupies the symbol before CORESET0 in the time domain. A multiplexing pattern of 3 indicates that CORESET0 and SSB occupy different resources in the frequency domain and occupy the same symbol in the time domain. The search space 0 configuration information is also used to indicate indexes 0 to 15. The configuration information corresponding to the index can be used to determine the time domain position of the search space 0, which is also the time domain position of CORESET0.

[0041] Exemplarily, the content of Table 1 is used to indicate the case where the {SS / PBCH block, PDCCH} subcarrier spacing combination is {15kHz, 15kHz} and the minimum channel bandwidth (minimum channel bandwidth) is 5MHz or 10MHz.

[0042] Table 1

[0043]

[0044]

[0045] However, the bandwidth capability of the first type of terminal cannot fully support the CORESET0 configuration shown in Table 1. For example, assuming that the bandwidth capability of the first type of terminal is 10 MHz, when CORESET0 is configured as 96 RBs, the occupied bandwidth is 17.28 MHz, and the first type of terminal cannot support the CORESET0. In the NR system, in order to be compatible with the access of the first type of terminal, the network side needs to configure a lower bandwidth for CORESET0 when configuring the initial access-related signal channel, such as 24 or 48 RBs, so that the CORESET0 configuration of indexes 12 to 14 will be restricted, thereby affecting the performance of the second type of terminal accessing the network.

[0046] Based on the defects in the above scenarios, Figure 2 A flowchart of an information acquisition method is provided, which can be applied to a first type of terminal, such as Figure 2 As shown, the method specifically includes:

[0047] S201. A first type terminal determines configuration information of a first CORESET0 corresponding to the first type terminal according to a PDCCH configuration signaling corresponding to SIB1 in MIB sent by a base station.

[0048] Among them, the CORESET0 corresponding to the PDCCH configuration signaling corresponding to SIB1 in the above MIB is the second CORESET0 corresponding to the second type of terminal.

[0049] Optionally, the second type of terminal is different from the first type of terminal in at least one of bandwidth, cost, complexity, processing capability, energy consumption, and device size.

[0050] If the first type terminal and the second type terminal receive the same SSB, they will receive the same 4-bit CORESET0 indication information, which indicates an index value. The first type terminal and the second type terminal can respectively obtain corresponding CORESET0 configuration information according to the same obtained index value.

[0051] Exemplarily, when the second CORESET0 corresponding to the above-mentioned second type terminal is applicable to the first type terminal, it means that the second CORESET0 is the same as the first CORESET0; conversely, if the second CORESET0 is not applicable to the first type terminal, the first type terminal obtains the first CORESET0 configuration information according to the PDCCH configuration signaling corresponding to SIB1 in the master information block MIB.

[0052] In the above manner, regardless of whether the CORESET0 configuration corresponding to the index sent by the base station exceeds the access capability of the first type of terminal, the first type of terminal can obtain the configuration information of the first CORESET0. In this way, when the first type of terminal and the second type of terminal coexist in the network, the first type of terminal can still correctly access the network according to the configuration information, thereby achieving the premise of not affecting the access performance of the second type of terminal to the network, and also ensuring that the first type of terminal can smoothly access the network according to the configuration information.

[0053] In the embodiment of the present application, the configuration information of the first CORESET0 is similar to the configuration information of the second CORESET0, and also includes the position relationship between the SSB and CORESET0, the number of resource blocks (RB) of CORESET0, Number of symbols in CORESET0 Four aspects of the frequency domain offset between CORESET0 and SSB.

[0054] In an example, when the frequency range of the carrier frequency is FR1, that is, 410 MHz to 7125 MHz, the configuration information corresponding to each index value of the first CORESET0 may be as shown in Table 2.

[0055] Table 2

[0056]

[0057]

[0058] It can be seen from Tables 1 and 2 that when the index sent by the base station is 0 to 11, the first type of terminal and the second type of terminal obtain the same configuration information, that is, obtain the same CORESET0, and when the first type of terminal cannot obtain the configuration information of CORESET0 corresponding to the index 12 to 14 in the prior art (that is, the second type of terminal) due to bandwidth limitations (for example, 10MHz), through the solution provided in the embodiment of the present application, the first type of terminal can correctly obtain the configuration information of CORESET0 corresponding to the index based on the first CORESET0 configuration information (that is, Table 2), thereby coexisting with the second type of terminal in the network.

[0059] It should be noted that the content of Table 2 above is only an exemplary presentation of the configuration information of the first CORESET0 when the subcarrier spacing combination of {SS / PBCH block, PDCCH} is {15kHz, 15kHz}, and does not limit the specific configuration information of the first CORESET0.

[0060] For example, it is assumed that the configuration information of indexes 12 to 14 in Table 2 is as shown in Table 3:

[0061] Table 3

[0062]

[0063] That is, when the number of RBs of the first CORESET0 is 48 RBs, in all RB number configuration situations (24, 48, 96) of the first CORESET0, it can not only meet the access conditions of the first type of terminal, but also provide a larger CORESET0 bandwidth relative to 24 RBs, and the configuration of 3 symbol numbers can also provide more time domain resources compared to 1 or 2 symbol numbers. In addition, the two different configurations of 2 and 3 symbol numbers can provide a certain flexibility in time domain configuration, and the frequency domain offset provides three different configurations of 12, 14, and 16, which can provide a certain flexibility in configuration, and the frequency domain position configuration of the first CORESET0 meets the principle of aligning the first CORESET0 and the SSB frequency center position as much as possible. Figure 3 In the example of Table 3, two possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are provided.

[0064] Optionally, the configuration information of indexes 12 to 14 in Table 2 above may also be as shown in Table 4 and Table 5:

[0065] Table 4

[0066]

[0067] Table 5

[0068]

[0069] Among them, the parameter k in Table 4 and Table 5 SSB Indicates subcarrier 0 of SSB and common resource block (CRB) The carrier offset of subcarrier 0 in the frequency domain, Indicates the CRB with the lowest frequency domain position among all CRBs that overlap with the SSB in the frequency domain.

[0070] In the case where the first CORESET0 multiplexing patterns provided in Tables 4 and 5 are configured as 2 and 3, the frequency division multiplexing of SSB and the first CORESET0 can make the first CORESET0 occupy less time domain resources and can effectively reduce the synchronization delay. The configuration of multiplexing patterns 2 and 3 not only provides flexibility in the time domain position of the first CORESET0, but also multiplexing pattern 3 can reserve more resources for the Physical Downlink Shared Channel (PDSCH); the positive and negative configurations of the frequency domain offset between SSB and the first CORESET0 also provide flexibility in the frequency domain position of the first CORESET0. Figure 4 In the examples of Table 4 and Table 5, several possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are shown.

[0071] In an example, when the frequency range of the carrier frequency is FR2, that is, 24250 MHz to 52600 MHz, and the {SS / PBCHblock, PDCCH} subcarrier spacing combination is {120 kHz, 60 kHz}, the configuration information of the first CORESET0 can be as shown in Table 6.

[0072] Table 6

[0073]

[0074]

[0075] Table 6 compares the different configuration information of the first CORESET0 and the second CORESET0. When the index sent by the base station is 0 to 9, the first type terminal and the second type terminal can obtain the same configuration information. When the index sent by the base station is 10 to 11, for the existing (or in the second CORESET0 configuration table) configuration information corresponding to indexes 10 and 11 that the first type terminal cannot obtain, the first type terminal can obtain the correct CORESET0 configuration information corresponding to indexes 10 and 11 based on Table 6 to ensure the smooth progress of subsequent steps. The second type terminal can obtain the CORESET0 configuration information corresponding to indexes 10 and 11 based on the second CORESET0 configuration table stored by itself, that is, the marked configuration information in Table 6. In this way, the coexistence of the first type terminal and the second type terminal in the network can be achieved.

[0076] It should be noted that the configuration information of the first CORESET0 in Table 6 is only presented for example, and does not limit the specific content of the configuration information of the first CORESET0.

[0077] For example, it is assumed that the configuration information of indexes 10 to 11 in Table 6 is as shown in Table 7:

[0078] Table 7

[0079]

[0080] In the example of Table 7, when SSB and the first CORESET0 are multiplexing pattern 1, the bandwidth satisfies the first CORESET0 configuration of 96 RB, which can provide a first CORESET0 with a larger bandwidth, and the configurations of 1 and 2 symbol numbers can achieve configuration flexibility. In addition, the frequency domain offset configuration of 28 RB can make the frequency domain position configuration of the first CORESET0 meet the principle of aligning the frequency center positions of the first CORESET0 and SSB as much as possible.

[0081] Figure 5 In the example of Table 7, two possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are provided.

[0082] Optionally, the configuration information of indexes 10 to 11 in Table 6 above may also be as shown in Table 8, Table 9, and Table 10:

[0083] Table 8

[0084]

[0085] Table 9

[0086]

[0087] Table 10

[0088]

[0089] When the multiplexing pattern of the first CORESET0 and SSB provided in Tables 8 to 10 is configured as 2 or 3, less time domain resources can be occupied, and such a configuration can make the synchronization delay lower. In addition, the frequency domain offset configuration of the first CORESET0 and SSB can also ensure that the first CORESET0 and the second CORESET0 do not affect each other. Figure 6 In the examples of Tables 8 to 10, several possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are provided.

[0090] In an example, when the frequency range of the carrier frequency is FR2 and the subcarrier spacing combination of {SS / PBCH block, PDCCH} is {120 kHz, 120 kHz}, the configuration information of the first CORESET0 can be as shown in Table 11.

[0091] Table 11

[0092]

[0093] Table 11 compares the different configuration information of the first CORESET0 and the second CORESET0. When the index sent by the base station is 6 to 7, the first type of terminal cannot obtain the existing (or second CORESET0) configuration information corresponding to indexes 6 and 7 due to bandwidth limitations (for example, 100 MHz). The first type of terminal can obtain the correct CORESET0 configuration information corresponding to indexes 6 and 7 based on Table 11 to ensure smooth access to the network. The second type of terminal can obtain the CORESET0 configuration information corresponding to indexes 6 and 7 based on the second CORESET0 configuration table stored in itself, that is, the marked configuration information in Table 11. In this way, when the base station sends the index, both the first type of terminal and the second type of terminal can obtain the configuration information corresponding to the index.

[0094] It should be noted that the configuration information of the first CORESET0 in the above Table 11 is only presented for example, and does not limit the specific content of the configuration information of the first CORESET0.

[0095] Exemplarily, it is assumed that the configuration information of indexes 6 to 7 in Table 11 is as shown in Table 12:

[0096] Table 12

[0097]

[0098] In the example of Table 12, SSB and the first CORESET0 are multiplexing pattern 1, and the bandwidth satisfies the configuration of the first CORESET0 of 48 RB, so the configuration of 48 RB can provide a first CORESET0 with a larger bandwidth than 24 RB, and the configuration of two symbol numbers of 1 and 2 realizes the flexibility of configuration. In addition, the frequency domain offset configuration of 14 RB can make the frequency domain position configuration of the first CORESET0 meet the principle of aligning the frequency center positions of the first CORESET0 and SSB as much as possible. Figure 7 In the example of Table 12, two possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are provided.

[0099] Optionally, the configuration information of indexes 6 to 7 in Table 11 above may also be as shown in Table 13, Table 14, and Table 15:

[0100] Table 13

[0101]

[0102]

[0103] Table 14

[0104]

[0105] Table 15

[0106]

[0107] In the examples provided in Tables 13 to 15, the first CORESET0 and SSB are configured with multiplexing pattern 2 or 3, which can occupy less time domain resources and reduce the synchronization delay. At the same time, the frequency domain offset configuration of the first CORESET0 and SSB can ensure that the first CORESET0 and the second CORESET0 do not affect each other. Figure 8 Several possible relative position relationships between SSB and the first CORESET0 and the second CORESET0 are provided in the examples of Tables 13 to 15.

[0108] In addition, the time-frequency resource blocks for the terminal to detect PDCCH are defined in CORESET0, and the time domain position of PDCCH detection (also known as Monitoring Occasion (MO)) is indicated by the search space configuration information. The search space of Type0 PDCCH, also known as Search Space Zero (SS0), can be indicated by the 4-bit indication field in MIB. As shown in Table 16, it is a schematic table of indication of search space 0 when the SSB and CORESET0 multiplexing pattern is 1.

[0109] Table 16

[0110]

[0111]

[0112] As shown in Table 16, the 4-bit indicator field in the MIB is used to indicate indexes 0 to 15. Different indexes correspond to a search space configuration. Each configuration includes the following four aspects: parameters O and M used to calculate the index of the time slot where the monitoring opportunity is located, the number P of search spaces in each time slot, and the starting symbol index S. Among them, parameters O and M are parameters well known in the art and are used to control the time slot used by the search space.

[0113] The second type of terminal can obtain the configuration information of search space 0 according to the indication of the 4-bit information. When the first CORESET0 and the second CORESET0 and the SSB occupy different symbols in the time domain and contain the SSB in the frequency domain, the first type of terminal can determine the time domain position of the search space of the first type of terminal according to the search space of the second type of terminal, and can also determine the time domain position of the search space of the first type of terminal according to the position of the SSB.

[0114] Optionally, the first type of terminal may determine the time domain position of the first type of terminal search space according to the position of the SSB, or according to the position of the SSB and an offset. The first type of terminal search space may be adjacent to the SSB in the time domain, for example, it may be in front of the SSB or behind the SSB. The offset may be a time slot level offset or a symbol level offset, and the offset may be positive or negative.

[0115] Optionally, the first type terminal may determine the time domain position of the second type terminal search space according to the search space configuration information of the second type terminal, and determine the time domain position of the first type terminal search space according to the time domain position of the second type terminal search space, or the time domain position and offset of the second type terminal search space. The search space of the first type terminal may be adjacent to the search space of the second type terminal, for example, in front of or behind the search space of the second type terminal. The offset may be an offset at a time slot level or an offset at a symbol level, and may be positive or negative.

[0116] Among them, in the above method, a time slot level offset can be understood as the offset between the time slot where the second type terminal search space corresponding to the SSB with index 0 is located and the time slot where the first type terminal search space is located within an SSB cycle.

[0117] Exemplarily, when the offset is a time slot level offset, for the SSB with index i, the time slot where the search space of the second type of terminal is located is the starting number Two consecutive time slots of Indicates the number of time slots contained in each frame for the subcarrier spacing configuration u. The value of u can be 0, 1, 2, or 3, corresponding to the subcarrier spacing of 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively. The first type of terminal can use the parameters O and M, as well as the maximum number of SSBs in a cycle L max , calculate the time slot resources that all search spaces of the second type of terminal need to occupy, and then perform a time slot level offset (offset_slot) based on the calculation result to determine the time domain position of the search space of the first type of terminal.

[0118] Furthermore, the time slot level offset also needs to satisfy at least the following conditions:

[0119]

[0120] On the basis of satisfying the above conditions, the time slot occupied by the search space of the first type of terminal can be adjacent to the time slot occupied by the search space of the second type of terminal, that is, within an SSB cycle, the starting time slot of the search space of the first type of terminal corresponding to the first SSB is adjacent to the last time slot occupied by the search space of the second type of terminal corresponding to the last SSB. Such a design not only does not affect the PDSCH configuration flexibility of the second type of terminal, but also can complete the synchronization of the first type of terminal as soon as possible.

[0121] In addition to the above method, the time slots occupied by the search space of the first type of terminals may also start from any time slot among the time slots not used by the second type of terminals.

[0122] In addition, except for the starting time slot, the rest of the first type of terminal search space configuration information parameters M L , the number of search spaces of the first type of terminals in each time slot P L and the first type terminal start symbol index S L It may be the same as or different from the configuration information of the second type terminal in the corresponding index. L The value can be 1 or 2. L The value of can be 1 or 1 / 2. L When the value of S is 1, L The value of can be any integer between 0 and 13, for example, 0, 1, 2, 7. L When the value of is 1 / 2, S L The value of can be {0, if i is an even number; if i is odd} or {0, if i is even; 7, if i is odd}, etc., i is the SSB index.

[0123] For example, when the maximum number of SSBs in one cycle is L max When the value of is 4, parameter O is 0, and M is 1, the time slots occupied by the second type terminal search space corresponding to the four SSBs in the cycle are slots 0 to 4. At this time, the first type terminal can start from slot 5 as the starting time slot of the first type terminal search space corresponding to the SSB with index 0, that is, offset_slot = 5. Let other parameters M L =1,P L =1, then the corresponding situation is Fig. 9 shown.

[0124] Optionally, when the parameter ML =1 / 2, P L =2, S L is {0, if i is even; 7, if i is odd} or {0, if i is even; If i is an odd number, the corresponding situation is as follows Fig.10 Or as shown in 11.

[0125] Exemplarily, when the offset is a symbol-level offset, the time slots where the search space of the first type of terminal and the search space of the second type of terminal are located will overlap. If the time slot where the search space of the first type of terminal is located is defined as the starting number The first type of terminal obtains the same parameter M as the second type of terminal, and the parameter O of the start time slot of the search space is determined. L It may be different from or the same as the second type terminal parameter O. This situation depends on the specific value of the second type terminal parameter O and the time domain position of the SSB, that is, O L The value of must ensure that the search space of the first type of terminal does not overlap with SSB, and then through the start symbol index S L Different implementations of symbol-level offsets from S, i.e., the search space starting symbol index S of the first type of terminal L There is an offset offset_symbol between the search space start symbol index S of the second type of terminal, and the offset satisfies the formula: S L =S+offset_symbol, and the offset needs to meet the conditions: in is the number of symbols occupied by the second CORESET0, that is, the offset is to ensure that the search spaces of the first type of terminal and the second type of terminal in the same time slot do not overlap. Of course, the search space of the first type of terminal in the same time slot can be adjacent to the search space of the second type of terminal, or it can occupy any symbol not occupied by the search space of the second type of terminal.

[0126] For example, assuming that the maximum number of SSBs in one cycle is L max The value of is 4, the values ​​of parameters O and M are 0 and 1 respectively, the second type terminal search space starting symbol index S = 0, Fig.12 Shown O L =2, This can avoid the overlap of the first CORESET0 and SSB and the second CORESET0, that is, in this case, the search spaces of the first type of terminal and the second type of terminal in the same time slot are in a close manner.

[0127] Optionally, when L maxThe value of is 4, the values ​​of parameters O and M are 2 and 1 respectively, and the starting symbol index S = 0. At this time, O L The value of is the same as the value of parameter O, such as Fig.13 As shown, it is O L =O=2, situation.

[0128] In addition, for the same SSB, the first CORESET0 may be before the second CORESET0, such as Fig.14 As shown, the maximum number of SSBs in one cycle is 4, parameters O = 2, M = 1, S = 0, O L =O-1, S L =S+offset_symbol=0+offset_symbol=12.

[0129] In another example, when the first CORESET0 and SSB occupy different symbols in the time domain and include SSB in the frequency domain, and the second CORESET0 and SSB occupy different resources in the frequency domain, the second CORESET0 has a fixed relative position with the SSB. At this time, the 4-bit indication field carried in the MIB for indicating the second type of terminal search space 0 configuration information is not used, and the indication field is used to indicate the first type of terminal search space 0 configuration information. The first type of terminal determines the position information of the first CORESET0 according to the search space 0 configuration information, and the search space 0 configuration information indicates the time domain position configuration parameters of the first CORESET0, for example, L 、M L , P L , S L , so that the first type of terminal obtains its own CORESET0 time domain position, the specific indication information can be in the form of a table to indicate the specific configuration of each index corresponding to the 4 bits, the table can be the same as the CORESET0 indication information schematic table of the second type of terminal, or a new table can be designed.

[0130] In one example, when the first CORESET0 and SSB occupy different resources in the frequency domain, the search space of the first type of terminal and the SSB have a fixed relative position and no signaling indication is required.

[0131] In addition, the first type of terminal may determine the time domain position of the first CORESET0 according to the second CORESET0 and the PDCCH configuration signaling in the following optional manners:

[0132] In the first way, when the PDCCH configuration signaling indicates that the relationship between the second CORESET0 and the SSB is that they occupy different symbols in the time domain, and the second CORESET0 includes the SSB in the frequency domain, then the relationship between the first CORESET0 and the SSB is that they occupy different symbols in the time domain, and the first CORESET0 includes the SSB in the frequency domain;

[0133] In the second manner, when the PDCCH configuration signaling indicates that the relationship between the second CORESET0 and the SSB is that they occupy different resources in the frequency domain, the relationship between the first CORESET0 and the SSB is that they occupy different resources in the frequency domain.

[0134] In an example, the first type of terminal determines whether the current cell supports access of the first type of terminal according to the first access indication information in the MIB. The first access indication information may be one of the following:

[0135] The first access indication information is the existing cell barring indication cellBarred in the MIB. In this case, both the first type terminal and the second type terminal determine whether they can access the current cell according to the cell barring indication;

[0136] Alternatively, the first access indication information occupies 1 bit of information reserved in the MIB, and is used to indicate whether a first type of terminal can access the current cell, and the cell prohibition indication is used to indicate whether a second type of terminal can access the current cell. For example, if the first access indication information is "1", it indicates that the first type of terminal is allowed to access, and if it is "0", it indicates that the first type of terminal is prohibited from accessing, or if the first access indication information is "0", it indicates that the first type of terminal is allowed to access, and if it is "1", it indicates that the first type of terminal is prohibited from accessing.

[0137] In one example, a first type of terminal determines whether the current cell supports access by the first type of terminal according to the access indication information field in DCI format 1_0, and the cell barring indication cellBarred in the MIB is only used to indicate whether the second type of terminal is allowed to access the current cell, that is, the first type of terminal can ignore the cell barring indication cellBarred in the MIB, and only determine whether it can access the current cell according to the access indication information field in DCI format 1_0.

[0138] Alternatively, the first type of terminal determines whether the current cell supports access by the first type of terminal according to whether the current cell is configured with the first CORESET0;

[0139] The access indication information corresponds to downlink control information transmitted in the first CORESET0, and the downlink control information is scrambled by SI-RNTI.

[0140] In one example, the access indication information field is used to indicate whether the current cell supports access by the first type of terminal. For example, when the network is configured so that the first CORESET0 and the second CORESET0 exist at the same time, if the first type of terminal can obtain the first CORESET0 according to the PDCCH configuration signaling in the MIB, the first type of terminal considers the cell to be an accessible cell; if only CORESET0 is configured in the network and the CORESET0 is not applicable to the first type of terminal, the first type of terminal considers the cell to be an inaccessible cell.

[0141] In an example, the SI-RNTI scrambled DCI format 1_0 includes access indication information of the first type of terminal and the second type of terminal. The information field in the SI-RNTI scrambled DCI format 1_0 includes at least one of the following:

[0142] Frequency domain resource assignment;

[0143] Time domain resource assignment;

[0144] Virtual resource block to physical resource block mapping (VRB-to-PRB mapping);

[0145] Modulation and coding scheme;

[0146] Redundancy version;

[0147] System information indicator;

[0148] Reserve bits.

[0149] The reserved bits occupy 15 bits. If only CORESET0 is configured in the network, and the CORESET0 can be applied to both the first type of terminal and the second type of terminal, the DCI format 1_0 corresponding to the access indication information is included in the CORESET0, and the information included in the SI-RNTI scrambled DCI format1_0 applicable to both the first type of terminal and the second type of terminal is at least one of the following:

[0150] Frequency domain resource assignment;

[0151] Time domain resource assignment;

[0152] Virtual resource block to physical resource block mapping (VRB-to-PRB mapping);

[0153] Modulation and coding scheme;

[0154] Redundancy version;

[0155] System information indicator;

[0156] First type terminal access indication information;

[0157] Reserve bits.

[0158] Both the first type of terminal and the second type of terminal can receive DCI format 1_0 encrypted with SI-RNTI, but the first type of terminal access indication is only valid for the first type of terminal, and the second type of terminal does not interpret the information field. The first type of terminal access indication information occupies the originally reserved bits, which can be 1 bit of signaling overhead. For example, "1" represents support for access of the first type of terminal, and "0" represents support for access of the first type of terminal; or "0" represents support for access of the first type of terminal, and "1" represents support for access of the first type of terminal. Of course, the existence of the access indication information field can also be used to indicate whether the access of the first type of terminal is supported. For example, if it exists, it means that the access of the first type of terminal is supported, and if it does not exist, it means that the access of the first type of terminal is not supported. In this case, the reserved bits occupy 14 bits. The access indication information field may also occupy 2 bits of signaling overhead to apply to the case where the first type of terminal is further divided into terminal types. The specific indication methods include but are not limited to the following cases: for example, "11" represents support for access of all first type terminals, "01" represents support for access of type A terminals in the first type of terminals, "10" represents support for access of type B terminals in the first type of terminals, and "00" represents no support for access of any first type of terminal. In this case, the reserved bits occupy 13 bits. The above-mentioned type A and type B represent different types of terminals in the first type of terminals that are further divided according to terminal capabilities.

[0159] In an example, the SI-RNTI scrambled DCI format 1_0 includes access indication information of the first type of terminal. The DCI format 1_0 corresponding to the access indication information is included in the first CORESET0 or the second CORESET0, and the DCI format 1_0 including the access indication information includes at least one of the following information:

[0160] Frequency domain resource assignment;

[0161] Time domain resource assignment;

[0162] Virtual resource block to physical resource block mapping (VRB-to-PRB mapping);

[0163] Modulation and coding scheme;

[0164] Redundancy version;

[0165] System information indicator;

[0166] First type terminal access indication information;

[0167] Reserve bits.

[0168] The first type of terminal access indication information occupies the originally reserved bits, which can be 1 bit of signaling overhead, for example, "1" represents support for access of the first type of terminal, "0" represents support for access of the first type of terminal; or "0" represents support for access of the first type of terminal, "1" represents support for access of the first type of terminal. Of course, the presence of the access indication information field can also be used to indicate whether the access of the first type of terminal is supported. For example, if it exists, it means that the access of the first type of terminal is supported, and if it does not exist, it means that the access of the first type of terminal is not supported. In this case, the reserved bits occupy 14 bits. The access indication information field can also occupy 2 bits of signaling overhead to apply to the situation where the first type of terminal is further divided into terminal types. The specific indication method includes but is not limited to the following situations: for example, "11" represents support for access of all first type terminals, "01" represents support for access of type A terminals in the first type of terminals, "10" represents support for access of type B terminals in the first type of terminals, and "00" represents support for access of any first type of terminal. The reserved bits occupy 13 bits. The above-mentioned type A and type B represent different types of terminals in the first type of terminals that are further divided according to terminal capabilities.

[0169] In one example, a first type of terminal determines whether the current cell supports access by the first type of terminal according to the first access indication information in the MIB, and the first access indication information is the cell barring indication cellBarred already in the MIB. At this time, the SI-RNTI-scrambled DCI format 1_0 also contains the first type of terminal access indication information. If the first access indication information in the MIB prohibits the first type of terminal from accessing the current cell, the first type of terminal does not access the current cell. If the first access indication information allows the first type of terminal to access the current cell, the first type of terminal determines whether to access the current cell according to the first type of terminal access indication information in the DCI format 1_0.

[0170] In an example, the first type of terminal determines the situation of the system message corresponding to the first type of terminal according to the first short information field in the DCI format 1_0.

[0171] The first short message corresponds to downlink control information transmitted in the first CORESET0, and the downlink control information is scrambled by the P-RNTI;

[0172] Alternatively, the first short message corresponds to downlink control information transmitted in the first CORESET0, the downlink control information is scrambled by P-RNTI, and the first short message and the second short message are transmitted in the same downlink control information, wherein the second short message is used to determine the system message corresponding to the second type of terminal.

[0173] In an example, the P-RNTI-scrambled DCI format 1_0 includes a paging message indication of a first type terminal and a second type terminal, and the information field in the P-RNTI-scrambled DCI format 1_0 includes at least one of the following:

[0174] Short messages indicator;

[0175] Short messages;

[0176] Frequency domain resource assignment;

[0177] Time domain resource assignment;

[0178] Virtual resource block to physical resource block mapping (VRB-to-PRB mapping);

[0179] Modulation and coding scheme;

[0180] Transport block size (TB scaling);

[0181] Reserve bits.

[0182] The reserved bits occupy 6 bits. The short message includes an indication of system information modification (systemInfoModification), which indicates a BCCH modification (BCCH modification) of the second type of terminal except SIB6, SIB7 and SIB8.

[0183] If the network is configured with only CORESET0, and the CORESET0 can be applied to both the first type terminal and the second type terminal, the P-RNTI scrambled DCI format 1_0 in the CORESET0 also includes a system information change indication of the first type terminal, and the information field included in the P-RNTI scrambled DCI format1_0 applicable to both the first type terminal and the second type terminal is at least one of the following:

[0184] Short messages indicator;

[0185] Short messages;

[0186] A first type of terminal system information change indication;

[0187] Reserve bits;

[0188] Alternatively, the information field included in the DCI format 1_0 for P-RNTI scrambling of both the first type terminal and the second type terminal is at least one of the following:

[0189] Short messages indicator;

[0190] Second short messages (Short messages) (applied to the second type of terminals);

[0191] A first short message (applicable to a first type of terminal);

[0192] Reserve bits.

[0193] Alternatively, the information field included in the DCI format 1_0 for P-RNTI scrambling of both the first type terminal and the second type terminal is at least one of the following:

[0194] Short messages indicator;

[0195] Short messages;

[0196] Reserve bits;

[0197] At this time, the system information change indication of the first type of terminal is included in the short message, using the reserved bits in the short message.

[0198] If the network configures both the first CORESET0 and the second CORESET0, the system information change indication or the short message applied to the first type of terminal is included in the DCI format 1_0 scrambled by the P-RNTI in the first CORESET0 or the second CORESET0.

[0199] The first type of terminal system information change indication occupies the originally reserved bits in DCI format 1_0, or occupies the reserved bits in the short message applied to the second type of terminal, indicating the broadcast control channel modification (BCCH modification) other than SIB6, SIB7 and SIB8, or indicating the BCCH modification including SIB6, SIB7 and SIB8. The system information change indication is a 1-bit overhead, for example, a bit of "1" indicates a change, or a bit of "0" indicates a change, or the presence of the bit can also be used to indicate whether the change is made, for example, a bit of "presence" indicates a change, or a bit of "non-presence" indicates a change; or, the first type of terminal system information change indication is a 2-bit overhead, so as to be applicable to the case where the first type of terminal is further divided into terminal types, and the specific indication method includes but is not limited to the following cases: for example, "11" indicates a system information change of all first type terminals, "10" indicates a system information change of type A terminals in the first type of terminals, "01" indicates a system information change of type B terminals in the first type of terminals, and "00" indicates that the system information of all first type terminals is not changed. The above-mentioned type A and type B represent different types of terminals further divided according to terminal capabilities in the first type of terminals.

[0200] Optionally, the first short message can be used at least to indicate whether the system message corresponding to the first type of terminal has changed. The size of the first short message can be the same as that of the second short message, or can be smaller than the second short message. For example, it only includes whether the system message corresponding to the first type of terminal has changed, or the type of PDSCH carrying SIB indicated by the DCI, and whether the system message corresponding to the first type of terminal has changed.

[0201] Fig.15 A flowchart of an information configuration method is provided, which can be applied to a base station, such as Fig.15 As shown, the method specifically includes:

[0202] S1501. The base station sends a PDCCH configuration signaling corresponding to SIB1 in the MIB.

[0203] The above-mentioned PDCCH configuration signaling is used to indicate the configuration information of the first CORESET0 corresponding to the first type of terminal, wherein the CORESET0 corresponding to the PDCCH configuration signaling corresponding to SIB1 in the MIB is the second CORESET0 corresponding to the second type of terminal.

[0204] Among them, when the second CORESET0 is applicable to the first type of terminal, the second CORESET0 is the same as the first CORESET0; otherwise, if the second CORESET0 is not applicable to the first type of terminal, the first type of terminal obtains the first CORESET0 configuration information according to the PDCCH configuration signaling corresponding to SIB1 in the MIB.

[0205] Optionally, when the second CORESET0 and the SSB occupy different symbols in the time domain, and the second CORESET0 includes the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different symbols from the SSB in the time domain and include the SSB in the frequency domain, wherein the position relationship between the configured first CORESET0 and the second CORESET0 includes:

[0206] The first CORESET0 and the second CORESET0 are configured to be adjacent in the time domain, for example, the first CORESET0 is in front of or behind the second CORESET0;

[0207] Alternatively, the first CORESET0 and the second CORESET0 are configured to be non-adjacent in the time domain, and there is an offset between the first CORESET0 and the second CORESET0, and the offset can be positive or negative.

[0208] In another example, when the second CORESET0 and the SSB occupy different symbols in the time domain and the second CORESET0 includes the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different symbols from the SSB in the time domain and include the SSB in the frequency domain, wherein the configured time domain position relationship between the first CORESET0 and the SSB includes:

[0209] The first CORESET0 is adjacent to the SSB in the time domain. For example, the first CORESET0 may be in front of the SSB or behind the SSB.

[0210] Alternatively, there is an offset between the first CORESET0 and SSB, and the offset can be positive or negative.

[0211] In one example, when the second CORESET0 and the SSB occupy different symbols in the time domain and the second CORESET0 includes the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different resources from the SSB in the frequency domain and have a fixed relative position with the SSB.

[0212] In one example, when the second CORESET0 occupies different resources from the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different symbols from the SSB in the time domain and include the SSB in the frequency domain, and indicates the location information of the first CORESET0 through the search space 0 configuration information, and the search space 0 configuration information is part of the PDCCH configuration information corresponding to SIB1 in the MIB.

[0213] In an example, when the second CORESET0 occupies different resources from the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different resources from the SSB in the frequency domain, and the first CORESET0 and the SSB have a fixed relative position.

[0214] In addition, the base station may associate the first CORESET0 with the second CORESET0, and the configuration method includes the following two methods:

[0215] When the second CORESET0 occupies different symbols from the SSB time domain and includes the SSB in the frequency domain, the base station configures the first CORESET0 to occupy different symbols from the SSB time domain and include the SSB in the frequency domain;

[0216] Alternatively, when the second CORESET0 and the SSB occupy different resources in the frequency domain, the base station configures the first CORESET0 to occupy different resources in the frequency domain with the SSB.

[0217] Furthermore, the base station may also configure different parameters for the first CORESET0 and the second CORESET0, and the different configured parameters include at least one of the different relative positions of CORESET0 and SSB, the different resource blocks RB occupied by CORESET0, the different number of symbols occupied by CORESET0 in the time domain, and the different frequency domain offsets between CORESET0 and SSB, wherein the frequency domain offset represents the offset between the frequency domain lower boundary of CORESET0 and SSB, with the RB of CORESET0 as the unit, a downward offset is expressed as positive, and an upward offset is expressed as negative, and the bandwidth of the first CORESET0 configured by the base station meets the bandwidth capability of the first type of terminal.

[0218] Exemplarily, the parameters of the above configuration are different, including at least one of the following:

[0219] When the first type of terminal supports a 10 MHz bandwidth in frequency range 1, or supports a 50 MHz bandwidth in frequency range 2, the base station may configure the first CORESET0 as at least one of the following:

[0220] When the subcarrier spacing of the first CORESET0 and SSB is 15KHz, the first CORESET0 and SSB occupy different symbols in the time domain and the first CORESET0 includes SSB in the frequency domain. The first CORESET0 occupies 48RB, and the number of symbols occupied in the time domain is at least one of 1, 2, and 3, and the frequency domain offset with SSB is at least one of 12RB, 14RB, and 16RB; or, the first CORESET0 and SSB occupy different resources in the frequency domain, the first CORESET0 occupies 24RB, and the number of symbols occupied in the time domain is at least one of 2 and 3, and the frequency domain offset with SSB is at least one of 24RB, -20RB, and -21RB; or, it is configured as any combination of the above two situations, and the combination of different situations is realized by different index values ​​indicated by the CORESET0 configuration information;

[0221] Alternatively, when the subcarrier spacings of the first CORESET0 and SSB are 30 KHz and 15 KHz respectively, the first CORESET0 and SSB occupy different symbols in the time domain and the first CORESET0 includes SSB in the frequency domain, the first CORESET0 occupies 24 RBs, the number of symbols occupied in the time domain is at least one of 1, 2, and 3, and the frequency domain offset with SSB is at least one of 5 RB to 8 RB;

[0226] Alternatively, when the first type of terminal supports a 20 MHz bandwidth in frequency range 1, or supports a 100 MHz bandwidth in frequency range 2, the base station may configure the first CORESET0 as at least one of the following:

[0230] In addition, in this embodiment, the base station may also send a first access indication for a first type of terminal, wherein the first access indication is carried in the MIB and is used to indicate whether the current cell supports access by the first type of terminal. Optionally, the first access indication may be a cell barring indication cellBarred already in the MIB, or the first access indication may occupy 1 bit of information reserved in the MIB to indicate whether the first type of terminal can access the current cell. In the second case, the cell barring indication is used to indicate whether the second type of terminal can access the current cell.

[0231] In one example, the base station may also send access control information of a first type of terminal, where the access control information of the first type of terminal is used to indicate whether the current cell supports access of the first type of terminal, wherein the access control information of the first type of terminal is carried in the downlink control information transmitted in the first CORESET0, the downlink control information format is DCIformat 1_0, and the downlink control information is encrypted by SI-RNTI.

[0236] Among them, the determination module is used to determine the configuration information of the first CORESET0 corresponding to the information acquisition device according to the PDCCH configuration signaling corresponding to SIB1 in the MIB sent by the base station, wherein the CORESET0 corresponding to the PDCCH configuration signaling corresponding to SIB1 in the MIB is the second CORESET0 corresponding to the second type of terminal.

[0237] The information acquisition device is different from the second type terminal in at least one of bandwidth, cost, complexity, processing capability, energy consumption, and device size.

[0238] In one example, if the second CORESET0 is applicable to the above-mentioned information acquisition device, the second CORESET0 corresponding to the second type terminal is the same as the first CORESET0 corresponding to the information acquisition device; conversely, if the second CORESET0 is not applicable to the information acquisition device, the determination module in the information acquisition device obtains the first CORESET0 configuration information according to the PDCCH configuration signaling corresponding to SIB1 in the MIB.
