In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in related technologies are described:

In one embodiment, the Master Information Block (MIB) already has a cell bar (cellbar) identifier to control whether the terminal is banned in the cell; at the same time, there is also a same-frequency reselection identifier in the MIB to control whether the terminal is banned in the cell. Controls whether the terminal is allowed to reselect co-frequency neighboring cells if the cell bar is configured in the MIB. If allowed, reselection to other cells with the same frequency is allowed. Otherwise, reselection to other cells with the same frequency is not allowed.

In one embodiment, the main technical features of the RedCap terminal are bandwidth reduction and reduction of receiving antennas. Among them, the maximum bandwidth is as follows:

The first frequency range (FR1, Frequency Range1): 20MHz (uplink or downlink);

Among them, the number of antennas is as follows:

FR1 frequency division multiplexing: 1RX;

FR1 time division multiplexing: 2RX or 1RX;

FR2:2RX.

It should be noted that operators are generally opposed to cells dedicated to RedCap terminals. Therefore, in the end, RedCap terminals need to read the original MIB Cell bar as the first step. Afterwards, the RedCap cellbar in the system information block SIB1 is used to determine whether to reside in the cell. At this time, there is a cellbar identifier specific to the RedCap terminal in SIB1, and 1RX and 2RX are distinguished. There is also an intra-frequency cell reselection indicator (IFRI, Intra-Frequency Cell Reselection Indicator) dedicated to RedCap terminals.

After the introduction of version R18 RedCap terminal, the bandwidth was further reduced, see Table 1, and was reduced to 5MHz or 20MHz.

In one embodiment, for R18 RedCap terminals, the baseband bandwidth and radio frequency band of the R18 RedCap terminal are reduced to 5M, and for Coreset#0 configured in the master information block (MIB, Master Information Block), most of None of the configurations are supported. Only the configuration of the control resource set CORESET#0 (SCS=15kHz and 24PRB) can be within the bandwidth range of 5Mhz; other configurations are not supported. Therefore, it is necessary to consider the solution for admission control after the introduction of R18 Redcap terminal.

For example, if the index value is a predetermined value, it indicates that SIB1-bis is not scheduled or Coreset#0bis used to schedule SIB1-bis does not exist.

For example, in one embodiment, an ordinary terminal obtains the type0 CSS information by receiving the fields carried by the MIB, and obtains the user equipment corresponding to different type0 CSS values through a predetermined mapping relationship to monitor the parameters of the PDCCH on CORESET0, such as the initial symbol position and time domain slot. The position and the number of search spaces in a slot, etc. Similarly, by newly adding a second predetermined mapping relationship, the relationship between the index value (Index), the number of search space sets in each time slot and/or the first symbol index (First symbol Index) is obtained. At this time, the second predetermined mapping relationship is different from the existing mapping relationship in which ordinary users obtain type0 CSS information through the fields carried in the MIB.

The index value can be obtained by interpreting the information bits carried in the MIB or the information bits carried by the PBCH, for example, by interpreting the low 4 positions of pdcch-ConfigSIB1 carried in the MIB.

For example, if the index value is a predetermined value, it indicates that SIB1-bis is not scheduled or the type0 CSS bis used to schedule SIB1-bis does not exist.

In one embodiment, the second predetermined system message indicates: resource information for scheduling the SIB1-bis message. 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. Exemplarily, the predetermined protocol interprets the information bits carried in the MIB or the information bits carried in the PBCH to obtain resource information indicating the SIB1-bis. In one embodiment, it is obtained through protocol predefined rules, for example, by reinterpreting the high 4 positions and low 4 bits of pdcch-ConfigSIB1. This field jointly encodes the time/frequency domain information of the SIB1-bis message. At this time, the information bits carried in the MIB or the information bits carried by the PBCH will directly carry the scheduling information of the scheduling SIB1-bis, that is, SIB1-bis uses the PDCCH less method to directly obtain the scheduling information at this time; compared with the terminal obtaining the scheduling SIB1 first The method of resource information of the physical downlink control channel PDCCH in the -bis message is faster.

Among them, after interpreting the information bit carried in the MIB or the information bit carried by the PBCH, if it is obtained as a predetermined code point or a predetermined value, it means that SIB1-bis has not been scheduled.

In one embodiment, for the scenario where the resource information of the physical downlink control channel PDCCH for scheduling the SIB1-bis message is still provided by the third resource information and the fourth resource information, the terminal interprets the information bit carried in the MIB or the information carried by the PBCH. The bit acquisition indicates whether the SIB1-bis is scheduled; for example, the PBCH carries an indication bit: when it is "0", SIB1-bis is not scheduled; when it is "1", SIB1-bis is scheduled. At this time, two types of SIB1, namely SIB1 and SIB1-Bis, will be scheduled by Coreset#0 and Type0 CSS.

In the embodiment of the present disclosure, it is determined whether a predetermined type of terminal is allowed to access the cell according to the acquisition result of the first predetermined system message. Here, since the terminal can determine whether to allow or not allow the predetermined type of terminal to access the cell according to the acquisition result of the first system message, the predetermined terminal can determine whether the network allows or does not allow the predetermined type according to the indication of the acquisition result. The type of terminal accesses the cell, and accesses the cell when it is determined that the network allows the terminal of the predetermined type to access the cell.

In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

In one embodiment, the predetermined type terminal determines whether admission control is allowed based on the first predetermined system message.

In one embodiment, the predetermined type of terminal is an R18 Redcap terminal, an R18 Redcap1RX terminal, or an R18 Redcap 2RX terminal.

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

In one embodiment, the predetermined type of terminal will obtain the first predetermined system message according to the information carried in the second predetermined system message (for example, MIB message).

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

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

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

Among them, the R18 Redcap terminal can obtain Coreset#0bis or type0 CSS bis through the protocol predefined rules (reinterpret the high 4 positions and low 4 bits of pdcch-ConfigSIB1).

For example, the following table 1 is defined for the R18 RedCap terminal to obtain the corresponding time domain and/or frequency domain position of Coreset#0bis.

Table I:

In one embodiment, the multiplexing mode of SSB and coreset can be limited to pattern1 (i.e., divisional multiplexing mode).

In one embodiment, a specific Index can be defined to have a predetermined meaning. For example, Index is 0, indicating that SIB1-bis is not scheduled or Coreset#0bis used to schedule SIB-bis does not exist. At this time, the predetermined type of terminal The cell will be determined to be a cell that is prohibited from access.

In one embodiment, the following table 1 is defined for R18 RedCap terminals to obtain the corresponding time domain and/or frequency domain positions of type0 CSS bis.

In one embodiment, a specific index is defined as a predetermined meaning. For example, Index is 0, indicating that SIB1-bis has not been scheduled or the type0 CSS used to schedule SIB-bis does not exist. At this time, the predetermined type terminal will determine This cell is a cell that is prohibited from access.

In one embodiment, R18 Redcap can obtain the time domain or frequency domain information of the scheduled SIB1-bis message through protocol predefined rules (reinterpret the high 4 positions and low 4 bits of pdcch-ConfigSIB1. This field is important for the SIB1-bis message. The time domain or frequency domain information is jointly coded (can also be combined with PCI, etc.); for example, the role of PCI coding is to distinguish the time/frequency domain resources of different cells.

At this time, pdcch-ConfigSIB1 will directly carry the scheduling information for scheduling SIB1-bis, that is, SIB1-bis uses PDCCH less to directly obtain the scheduling information at this time; in one embodiment, specific code points can be limited to predetermined meanings. For example, code point = 0, indicating that SIB1-bis is not scheduled.

In one embodiment, if the acquisition of the first scheduled system message fails (SIB1-bis is not scheduled, or Coreset#0bis or type0 CSS bis used to schedule SIB-Bis does not exist), the terminal will perform at least one of the following operate:

The predetermined type of terminal determines the cell as a cell that is prohibited from access;

The cell reselection indicator IFRI can be determined according to the agreement to allow intra-frequency cell reselection or not to allow intra-frequency cell reselection; or it can be determined based on the IFRI in the MIB.

In one embodiment, if the first system message is successfully obtained, the predetermined type of terminal is allowed to access (at this time, there is no need to further determine the 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 obtained successfully, the first system message will carry the admission control parameters of the predetermined type of terminal.

In one embodiment, the parameter is a cell bar parameter of a predetermined type of terminal, for example, a parameter of the field cellBarredRedCap-r18. If this field does not exist, it means there is no prohibition (bar). If this field exists, the cellbar parameter is obtained according to its identification, for example, bar or not bar; (at this time, the terminal needs to ignore the cellbar operation in the MIB). If it is cellbar, The cell reselection parameters will be based on the following embodiments): or the parameters of Cellbar and cellBarredRedCap-r18 in the MIB will be combined and determined. For example, if the Cellbar in the MIB is allowed, then the parameter cellBarredRedCap-r18 is judged. If it is allowed, access is allowed; if it is not allowed, access is not allowed. If the Cellbar in the MIB is not allowed, access must not be allowed.

This parameter is the cell bar parameter of a predetermined type of terminal, for example, the parameter of the field intraFreqReselectionRedCap-r18. If this field does not exist, it means cell bar; at this time, the cell reselection indicator IFRI can be allowed to perform intra-frequency cell reselection according to the agreement, or not allowed to perform intra-frequency cell reselection, or determined according to the IFRI in the MIB.
