In order to facilitate the examiners to understand the technical features, content and advantages of the present invention and the effects that can be achieved, the present invention is hereby described in detail as follows in the form of embodiments with the accompanying drawings and accessories, and the drawings used therein , the purpose of which is only for illustration and auxiliary description, and may not necessarily be the real scale and precise configuration after the implementation of the present invention. Therefore, the proportion and configuration relationship of the attached drawings should not be interpreted or limited to the application of the present invention in actual implementation. Scope, to be described first.

In the research process, it was noticed that under the terminal access mechanism in the related art, all terminals in the cell must detect and receive the PDCCH of SIB1 according to the same frequency bandwidth and the same period, which means that the connection in the related art The access method cannot support the access of small-bandwidth terminals, and cannot broadcast different system information for different terminals.

However, low-capacity terminals will inevitably be introduced into the network. Such terminals are characterized by low hardware cost, long standby time, and a large number of terminals. Correspondingly, its transmission bandwidth is often very small, such as several MHz. When the terminal in the related art accesses the network, it needs to detect and receive the PDCCH that schedules the transmission of SIB1 in CORESET#0. CORESET#0 and the related configuration of the corresponding search space are indicated by the 8-bit information in the MIB.

However, considering that the bandwidth supported by low-capacity terminals is small, it may not be able to support the bandwidth of CORESET#0; the requirements for access delay are also different (for example, longer access time can be allowed); requirements for system information May also be different, meaning separate SIB1 information is required.

However, in the system in the related art, only one set of CORESET#0 and SS#0 configurations can be obtained by receiving the same SSB. There is no solution in the related art to solve this problem.

In the implementation, it may further include: based on the 1-bit indication information carried by the MIB, determining whether the MIB is used to indicate the configuration information of CORESET#0 and SS#0 of the first type terminal or the second type terminal.

In a specific implementation, the 1-bit indication information is a reserved bit (reserved bit) in the MIB.

In a specific implementation, the 1-bit indication information is indicated as follows: 0 or 1 indicates that the MIB is used to indicate the CORESET#0 and SS#0 related configurations of the first type terminal and the second type terminal; and/or, 1 or 0 Indicates that the MIB is only used to indicate the relevant configuration of CORESET#0 and SS#0 of the first type terminal or the second type terminal.

For the base station side, the base station sends the SSB, and the MIB carried on the PBCH carries the relevant configuration information of CORESET#0 and SS#0.

In the implementation, the base station sends PDCCHs corresponding to different types of terminals corresponding to the CORESET and the corresponding CSS detection period, including: the base station sends the downlink control of scheduling its corresponding SIB1 in the CORESET#0 and SS#0 corresponding to the first type of terminals. channel; and, The base station sends and schedules the downlink control channel of the corresponding SIB1 in the CORESET#0 and SS#0 corresponding to the second type of terminal.

Specifically, the base station sends and schedules the downlink control channel of the corresponding SIB1 in the CORESET#0 and SS#0 corresponding to the first type of terminal.

The base station sends and schedules the downlink control channel of the corresponding SIB1 in the CORESET#0 and SS#0 corresponding to the second type of terminal.

Examples are given below.

Example 1:

It is assumed that there are two types of terminals in the system, namely the first type of terminal and the second type of terminal. In this embodiment, the terminals of the first type are terminals with normal capabilities, and the terminals of the second type are terminals with low capabilities.

The terminals all access the network through the same SSB, that is, receive the same SSB. After receiving the same MIB information transmitted in the SSB, the terminal parses the CORESET#0 and SS#0 configuration information in the MIB. According to its type, determine the transmission position of CORESET#0 and SS#0 indicated by the information in the MIB.

For example, for the first type of terminal, which supports a larger transmission bandwidth, the CORESET#0 and SS corresponding to the first type of terminal are determined according to the combination of SSB and the sub-carrier spacing (SCS) of CORESET#0 Determine the table used to indicate CORESET#0 and SS#0 in the #0 configuration table set, and determine which row of parameters in the table is used to determine the resource configuration of CORESET#0 according to the corresponding bit (bit) information in the MIB. Time domain location of SS#0 transmission.

For the second type of terminal, the supported transmission bandwidth is small, or it is not sensitive to the access delay. After parsing the MIB information, the corresponding table is selected from the CORESET#0 and SS#0 configuration tables corresponding to the second type of terminal. The selection rule may be the same as the rule of the first type of terminal selection table, for example, selection is made according to the combination of the SSB and the subcarrier spacing of CORESET#0.

In this example, it is assumed that the SCS of SSB and CORESET#0 are both 15kHz. Assume that the indication bits in the MIB used to indicate the CORESET#0 resource and the SS#0 transmission time domain position are 00000001, of which the upper 4 bits are used to indicate the relevant configuration of CORESET#0, specifically, to indicate the configuration parameters in the CORESET#0 configuration table The low-order 4 bits are used to indicate the relevant configuration of SS#0, specifically, to indicate the number of rows of configuration parameters in the SS#0 configuration table. In this embodiment, CORESET#0 is determined by the combination of parameters in the first row of its configuration table, and SS#0 is determined by the combination of parameters in the second row of its configuration table.

For example, the table of CORESET#0 and SS#0 corresponding to the first type of terminal is as follows, in which the entry (record) indicated in bold represents the CORESET#0 and SS#0 configuration of the terminal:

For example, the table of CORESET#0 and SS#0 corresponding to the second type of terminal is as follows, where the bold entry represents the CORESET#0 and SS#0 configuration of the terminal:

FIG. 3 is a schematic diagram showing the configuration of CORESET#0 and SS#0 determined by different types of terminals through the same MIB information. The specific configuration of CORESET#0 and SS#0 determined by different types of terminals through the same MIB information is shown in the figure.

Example 2:

As shown in Embodiment 1, there may be more types of terminals, which are not limited in any way. For specific implementation, reference may be made to Embodiment 1.

For example, a terminal with more capability levels, such as a terminal with lower capability than an NR lite terminal. For example, for other types of terminals, such as the integrated space-terrestrial terminal, which need to detect and receive satellite signals, etc., refer to Embodiment 1 in the specific implementation.

Example 3:

For the table corresponding to the first type terminal and the table corresponding to the second terminal, it should be ensured that the PDCCH used by the first type terminal for scheduling SIB1 and the PDCCH used by the second type terminal for scheduling SIB1 do not overlap in resources.

Specifically, the two CORESET#0s do not overlap at all in resources, or the transmission time domain positions of SS#0 do not overlap at all, or the time domain positions of CORESET#0 and SS#0 transmissions do not overlap at all. The specific parameters of the second type of table need to meet the relevant requirements of the second type of terminal, such as bandwidth, such as transmission delay and so on.

It should be noted that, during implementation, there is no limitation on the specific parameter combinations of the CORESET#0 and SS#0 configuration tables corresponding to the first-type terminal and the second-type terminal. That is, the parameters of each row in the table corresponding to the terminal of the first type and the terminal of the second type may be the same or different.

Further, during implementation, the number of rows included in the configuration table corresponding to the first type of terminal and the configuration table corresponding to the second type of terminal is also not limited.

Example 4:
