in one embodiment, there is already a control in the master information block (MIB, master Information Block) whether the terminal is barred in the cell by a cell barring (cellbar) identity; meanwhile, the MIB also has the function of controlling whether the terminal allows the same-frequency neighbor cell reselection under the condition that the cell is configured with the cellbar in the MIB through the same-frequency reselection identifier. If so, then the reselection to other cells of the same frequency is allowed to continue, otherwise, the reselection to other cells of the same frequency is not allowed.

Also, by newly adding the second predetermined mapping relationship, a relationship among an Index value (Index), the number of search space sets per slot, and/or the first symbol Index (First symbol Index) is obtained. At this time, the second predetermined mapping relationship is different from the mapping relationship of the type0 CSS information obtained by the existing common user through the fields carried in the MIB

The index value may be obtained from an information bit carried in the interpretation MIB or an information bit carried in the PBCH, for example, from a low 4 position of the pdfch-ConfigSIB 1 carried in the interpretation MIB.

Illustratively, if the index value is a predetermined value, it indicates that SIB1-bis are not scheduled or that type0 CSS bis for scheduling SIB1-bis do not exist.

In one embodiment, the second predetermined system message indicates: scheduling resource information of the SIB1-bis message. The resource information includes time domain and/or frequency domain resource information.

In one embodiment, the resource information is determined based on a predetermined protocol of a predetermined type of terminal. Illustratively, the predetermined protocol interprets an information bit carried in the MIB or an information bit carried in the PBCH to obtain resource information indicating the SIB 1-bis. In one embodiment, the high 4 and low 4 bits of the pdcch-ConfigSIB1 are retrieved by protocol predefined rules, e.g., re-interpreted, which field jointly encodes the time/frequency domain information of the SIB1-bis message. At this time, the information bit carried in the MIB or the information bit carried in the PBCH directly carries the scheduling information of the scheduling SIB1-bis, namely the SIB1-bis directly obtains the scheduling information by adopting a PDCCH less mode at this time; compared with the mode that the terminal firstly acquires the resource information of the physical downlink control channel PDCCH for scheduling the SIB1-bis message, the method has the characteristic of rapidness.

And if the information bit carried in the MIB or the information bit carried in the PBCH is obtained as a preset code point or a preset value, the SIB1-bis is indicated not to be scheduled.

In one embodiment, for a scenario that resource information of a Physical Downlink Control Channel (PDCCH) for scheduling an SIB1-bis message is still provided by third resource information and fourth resource information, a terminal acquires an instruction whether the SIB1-bis is scheduled or not by reading an information bit carried in an MIB or an information bit carried in a PBCH; for example, the PBCH carries an indication bit: when "0", SIB1-bis are not scheduled; when "1", SIB1-bis is scheduled. At this time, two SIB1 s, SIB1 and SIB1-Bis, will be CSS scheduled by Coreset #0 and Type 0.

For a better understanding of the embodiments of the present disclosure, the following further describes the technical solution of the present disclosure by means of an exemplary embodiment:

in one embodiment, the predetermined type of terminal decides whether admission control is allowed or not based on the first predetermined system message.

In one embodiment, the predetermined type of terminal is an R18 recap terminal, an R18 recap 1RX terminal, or an R18 recap 2RX terminal.

In one embodiment, the first predetermined system message is a SIB1 message. Illustratively, the first predetermined system message is a SIB1-bis message. It should be noted that SIB1-bis may be distinguished according to different antennas, for example, if different antennas are distinguished, SIB1-bis may be classified into SIB1-bis1 and SIB1-bis2.

In one embodiment, a predetermined type of terminal will acquire the first predetermined system message based on information carried in a second predetermined system message (e.g., MIB message).

In one embodiment, the scheduled time domain or frequency domain information of the first predetermined system message is carried by a MIB message.

In one embodiment, the time or frequency domain information of the PDCCH scheduling the SIB1-bis message is Coreset#0bis or type0 CSS bis.

In one embodiment, the time or frequency domain information of the PDCCH scheduling the SIB1-bis message is Coreset#0 or type0 CSS.

Wherein the R18 repap terminal can obtain Coreset #0bis or type0 CSS bis (re-interpret the upper 4 and lower 4 bits of the pdcch-ConfigSIB 1) through the protocol predefined rules.

For example, the following table is defined-corresponding time and/or frequency domain locations for the R18 RedCap terminal to acquire Coreset #0 bis.

Table one:

in one embodiment, the multiplexing mode that can define SSB and coreset is limited to pattern1 (i.e., time-division multiplexing mode) only.

In one embodiment, a specific Index may be defined as a predetermined meaning, illustratively, index is 0, indicating that SIB1-bis is not scheduled or Coreset #0bis for scheduling SIB-bis is not present, at which time a predetermined type of terminal may determine that the cell is a barred access cell.

In one embodiment, the following table is defined-corresponding time and/or frequency domain locations for the R18 RedCap terminal to acquire type0 CSS bis.

In one embodiment, defining a particular Index as a predetermined meaning, illustratively, index as 0, means that SIB1-bis is not scheduled or that type0 CSS for scheduling SIB-bis does not exist, at which point a predetermined type of terminal may determine that the cell is a cell for which access is prohibited.

In one embodiment, R18 Redcap may obtain time or frequency domain information of the scheduled SIB1-bis message through a protocol predefined rule (re-interpreting the upper 4 and lower 4 bits of the pdcch-ConfigSIB1, which field jointly encodes the time or frequency domain information of the SIB1-bis message (possibly in combination with PCI, etc.), e.g., with PCI encoding, which serves to distinguish time/frequency domain resources of different cells.

At this time, the PDCCH-ConfigSIB1 directly carries the scheduling information of the scheduling SIB1-bis, namely the SIB1-bis directly acquires the scheduling information by adopting a PDCCH less mode at this time; in one embodiment, a particular code point may be defined as a predetermined meaning. For example, code point=0, indicating that SIB1-bis is not scheduled.

In one embodiment, if the first predetermined system message acquisition fails (SIB 1-Bis is not scheduled, or Coreset #0Bis or type0 CSS Bis for scheduling SIB-Bis does not exist), the terminal will perform at least one of the following operations:

a terminal of a preset type determines the cell as a cell forbidden to be accessed;

the cell reselection identifier IFRI may be configured to allow or disallow the same-frequency cell reselection according to a protocol convention; or from an IFRI in the MIB.

In one embodiment, if the first system message acquisition is successful, the predetermined type of terminal access is allowed (at this point, no further decision is needed for SIB1-bis content). In one embodiment, the terminal needs to ignore the operation of prohibiting cell access in the MIB.

In one embodiment, if the first system message is successfully acquired, the first system message will carry admission control parameters of the terminal of the predetermined type.

In one embodiment, the parameter is a cell bar parameter of a predetermined type of terminal, e.g., a parameter of field cellBarredRedCap-r 18. If the field does not exist, it indicates that there is no prohibition (bar), and if the field exists, the cellbar parameter is acquired according to its identification, e.g., bar or not bar; (where the terminal needs to ignore the cellbar operation in MIB), the cell reselection parameters will be based on the following embodiment) if cellbar: or the parameters of Cellbar and cellBarredRedCAP-r18 in the MIB are combined and judged. If the Cellbar in the MIB is allowed, judging the parameters of the cellBarredRedCAP-r18, and if the parameters are allowed, allowing access; and if it is not, access is not allowed. In the case where Cellbar in MIB is not allowed, then access is necessarily not allowed.

The parameter is a cell bar parameter of a predetermined type of terminal, for example, a parameter of the field intrafreqresulectionredcap-r 18. The absence of this field indicates cell bar; at this time, the cell reselection identifier IFRI may be defined according to a protocol as allowing the same-frequency cell reselection, or not allowing the same-frequency cell reselection, or determined according to the IFRI in the MIB.
