As shown in fig. 2, an embodiment of the present disclosure provides an access control information processing method, including:

s110: determining access control information of a first type of UE, wherein the access control information indicates at least one of the following:

forbidding the first type UE to access the cell;

allowing the first type of UE to access the cell;

The method can be applied to a base station or a UE.

The first class of UEs may include, but is not limited to: redcap UE.

The prohibiting the first type of UE from accessing the local cell and the allowing the first type of UE to access the local cell may be indicated by different bit values of the same bit.

For example, different bit values of the cell barring identity of the first type UE indicate that the first type UE is allowed to access the cell or the first type UE is prohibited from accessing the cell. For example, the cell barring identity may be 1 bit, and the bit has two values of "0" and "1". Two values of the bit can respectively indicate that the first type UE is allowed to access the cell and the first type UE is forbidden to access the cell.

In an embodiment, the prohibiting the UE of the first type from reselecting to the co-frequency neighboring cell of the local cell and the allowing the UE of the first type to reselect to the co-frequency neighboring cell of the local cell may be indicated by different bit values of the same bit. For example, the first type of UE has an intra-frequency reselection flag, which has at least 1 bit, and the bit also has two values, i.e., "0" and "1". Two values of the bit can respectively indicate that the first-class UE is allowed to reselect the same-frequency adjacent cell of the cell and prohibit the first-class UE from reselecting the same-frequency adjacent cell of the cell.

Of course, in some embodiments, the 4 kinds of information may share the same or be indicated by using different bits respectively, and the specific examples are not limited to the above.

In the embodiment of the present disclosure, for the first type of UE, the access control information is configured, so that the access of the first type of UE in the local cell and the co-frequency neighboring cell of the local cell can be well controlled, and the first type of UE has a characteristic of good access control.

In one embodiment, the S110 may include: access control information provided to the first type of UE is transmitted.

For a base station, the transmitting access control information of the first type of UE includes: issuing access control information of first-class UE; and/or, for a base station, the transmitting access control information of the first type of UE includes: and receiving access control information of the first type of UE.

In some embodiments, as shown in fig. 3, the transmitting the access control information provided to the first type of user equipment UE includes:

and transmitting a Master Information Block (MIB) carrying the access control Information of the first type of UE.

The MIB is generally a system message block sent on a Broadcast Channel (BCH), and carries the most basic and commonly used information for wireless communication between the UE and the base station. The access control information of the first type UE is carried in the MIB for sending, so that the first type UE can receive the MIB on the BCH without a request-based mode, and access control is carried out on the first type UE based on the access control information carried in the MIB.

In some embodiments, the MIB comprises:

the cell forbidden identifier of the first type UE indicates that the first type UE is allowed or forbidden to access the cell;

and/or the presence of a gas in the gas,

and the same-frequency reselection identification of the first type UE indicates that the first type UE is allowed or forbidden to reselect the adjacent cell of the cell.

Before the MIB introduces the access control information of the first type of UE, the MIB does not contain the cell forbidden identifier and/or the same-frequency reselection identifier of the first type of UE. After the MIB introduces the access control information of the first type of UE, equivalently introducing the cell forbidden identifier and/or the same-frequency reselection identifier into the MIB.

The first-class UE cell forbidden identifier and/or the same-frequency reselection identifier introduced in the MIB may be 1 bit, and two bit values of this bit respectively indicate whether to allow the first-class UE to access the cell and whether to allow the first-class UE to reselect to a same-frequency neighboring cell.

In one embodiment, the cell forbidden identifier of the first type UE is a reserved bit of the MIB, and the co-frequency reselection identifier of the first type UE is an extended bit of the MIB;

or,

the cell forbidden identifier of the first type UE is an extension bit of the MIB, and the same-frequency reselection identifier of the first type UE is a reserved bit of the MIB.

There are reserved bits for the entire MIB, which may not be divided into any defined information fields of the MIB and which temporarily do not indicate a meaning.

Because two bits are needed when the first-class cell forbidden identifier and/or the same-frequency reselection identifier are introduced into the MIB, on one hand, the adjustment of the format of the MIB is reduced as much as possible, and on the other hand, an extension bit is introduced into the MIB, so that the bits contained in the MIB are increased, and therefore the first-class UE and the second-class UE can adopt different bits to respectively indicate whether to allow access to the cell and reselect to the same-frequency neighboring cell.

The reserved bit and the extended bit can be respectively used as a cell forbidden identifier and the same-frequency reselection identifier of the first type of UE. For example, the original reserved bits of the MIB are used as the cell barring identity of the first type of UE, and the extension bits are used as the co-frequency reselection identity of the first type of UE; or, the original reserved bit of the MIB is used as the co-frequency reselection identification of the first type of UE, and the extended bit is used as the cell forbidden identification of the first type of UE.

In one embodiment, the MIB further comprises: access control information of a second type of UE; and the bandwidth supported by the second type of UE is greater than the bandwidth supported by the first type of UE.

The second type of UE may be understood as any UE other than the first type of UE. For example, the second type of UE may be any UE proposed previously in the first type of UE. For example, assuming the first type of UE is a Redcap UE, the second type of UE may be an NR UE including, but not limited to: enhanced Mobile bandwidth (eMBB) UE.

The MIB is originally configured with access control information for the second type of UE. The bandwidth supported by the second type of UE is larger than the bandwidth supported by the first type of UE; and/or the power consumption of the second type of UE is greater than the power consumption of the first type.

In some embodiments, the MIB comprises:

jointly encoding the bits;

wherein different bit values of the joint coding bit respectively indicate whether the first type of UE and the second type of UE allow access to the cell; and whether the first type of UE and the second type of UE allow to reselect the same-frequency neighbor cell of the local cell or not.

Since the MIB originally has the cell barring identity and/or the same frequency reselection identity of the second type UE, it is intended to indicate the access control information of the first type UE and the second type UE at the same time. In the embodiment of the present disclosure, joint coding indication may be performed by combining the cell forbidden identifier of the second type of UE and/or the co-frequency reselection cell originally existing in the MIB, and adding one or more of the reserved bits, the extended bits, or the reserved bits of the specific information field of the entire MIB.

The reserved bits of the MIB are: the information belongs to idle bits which are not used in the whole MIB and does not belong to a specific information domain in the MIB. And the reserved bits for a particular information field are: the idle bits which are not used in the specific information domain belong to the specific information domain.

In one embodiment, the jointly coded bits comprise 3 bits, each comprising: and configuring a cell forbidden identifier of the second type UE, a same frequency reselection identifier of the second type UE and a reserved bit of the MIB in the MIB.

The joint coding bits for joint coding in the embodiment of the present disclosure are cell forbidden identifiers configured for the second type of UE in the MIB, co-frequency reselection identifiers of the second type of UE, and reserved bits of the MIB. In this way, even if new bits are not introduced into the MIB, the number of bits contained in the MIB and the information format of the MIB are not changed, and therefore compatibility with the MIB in the related art is high.

In one embodiment, the 8 bit values of the 3 bits may respectively indicate:

forbidding a second type of UE to access the local cell, allowing the second type of UE to reselect a same-frequency adjacent cell of the local cell and allowing the first type of UE to access the local cell;

forbidding the second type UE to access the local cell, forbidding the second type UE to reselect the same-frequency adjacent cell of the local cell and allowing the first type UE to access the local cell;

allowing the second type of UE to access the local cell, forbidding the first type of UE to access the local cell and allowing the first type of UE to reselect the same-frequency adjacent cell of the local cell;

allowing the second type of UE to access the local cell, forbidding the first type of UE to access the local cell and forbidding the first type of UE to reselect the same-frequency adjacent cell of the local cell;

prohibiting a second type of UE from accessing the local cell, permitting the second type of UE to reselect the same-frequency adjacent cell of the local cell, prohibiting a first type of UE from accessing the local cell and permitting the first type of UE to reselect the same-frequency adjacent cell of the local cell;

prohibiting a second type of UE from accessing the local cell, permitting the second type of UE to reselect the same-frequency adjacent cell of the local cell, prohibiting the first type of UE from accessing the local cell and prohibiting the first type of UE from reselecting the same-frequency adjacent cell of the local cell;

forbidding a second type of UE to access the local cell, forbidding the second type of UE to reselect to a same-frequency adjacent cell of the local cell, forbidding the first type of UE to access the local cell and allowing the first type of UE to reselect to the same-frequency adjacent cell of the local cell;

and prohibiting the second type of UE from accessing the local cell, prohibiting the second type of UE from reselecting the same-frequency adjacent cell of the local cell, prohibiting the first type of UE from accessing the local cell and prohibiting the first type of UE from reselecting the same-frequency adjacent cell of the local cell.

If the UE allows access to the local cell, the UE of either the first type or the second type gives priority to access to the local cell. If the UE accesses the MIB of the local cell, it indicates that the UE is located within the coverage area of the local cell, so that the communication quality of the wireless communication link between the UE and the local cell is good. In view of this, if at least one of the first type of UE and the second type of UE allows access to the cell, it is not so important, or even not indicated, whether the UE supports reselection to the co-frequency neighboring cell. For example, the cell barring identity of the second type of UE indicates that the second type of UE is allowed to access the local cell, and it is less important whether the second type of UE supports reselection to the same-frequency neighboring cell, so the same-frequency reselection identity of the second type of UE may be multiplexed to indicate whether the first type of UE is allowed to access the local cell or whether the first type of UE supports reselection to the same-frequency neighboring cell.

Therefore, considering the above situation, whether the first type UE and the second type UE allow to support accessing the local cell and whether to support reselection to the co-frequency neighboring cell has 9 optional scenarios, and each scenario is as follows:

scene 1: NR UE is allowed to access the cell, and Redecapap UE is allowed to access the cell;

scene 2: NR UE is forbidden to access the cell, supports NR UE to reselect to the same-frequency neighbor cell and allows the Redcap UE to access the cell;

scene 3: NR UE is forbidden to access the cell, NR UE is not supported to be reselected to a same-frequency neighbor cell, and Redcap UE is allowed to access the cell;

scene 4: NR UE is allowed to access the local cell, Redcap UE is supported to reselect to the same-frequency neighbor cell, and the Redcap UE is allowed to access the local cell;

scene 5: NR UE is allowed to access the local cell, does not support the Redcap UE to reselect to the same-frequency adjacent cell, and the Redcap UE is forbidden to access the local cell;

scene 6: NR UE is forbidden to access the local cell, NR UE is supported to reselect to a same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is supported to reselect to the same-frequency adjacent cell;

scene 7: NR UE is forbidden to access the local cell, NR UE is supported to reselect to a same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is not supported to reselect to the same-frequency adjacent cell;

scene 8: NR UE is forbidden to access the cell, NR UE is not supported to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the cell, and Redcap UE is not supported to reselect to the same-frequency adjacent cell;

scene 9: NR UE is forbidden to access the cell, NR UE is not supported to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the cell, and Redcap UE is not supported to reselect to the same-frequency adjacent cell.

3 joint coding bits, having 8 values, can indicate any 8 kinds of them, and the rest may not indicate.

In the embodiment of the present disclosure, scene 1 may be a scene that is not indicated by the above-mentioned 3 joint coding bits.

Scenario 1 may not be indicated in one embodiment.

In one embodiment, when at least one bit of the 3 bits is missing in the MIB, the MIB indicates: whether the first type of UE and the second type of UE allow to access the local cell and reselect to at least one scene in the same-frequency adjacent cell. Illustratively, the MIB lacking at least one of the 3 bits may indicate, but is not limited to, the following scenarios: and allowing the first type of UE to access the local cell and allowing the second type of UE to access the local cell.

For example, when 1 bit, 2 bits, or 3 bits of the 3 jointly coded bits are missing in the MIB, scenario 1 above indicated by the 3 jointly coded bits may be considered. In short, if part or all of the three joint coded bits are missing in the MIB, it can be considered that scenario 1 indicated by the 3 joint coded bits is described above. For example, if the MIB lacks bits of the cell barring identity and/or the co-frequency reselection identity configured to the second type of UE, it may be considered that the base station indicates that both the first type of UE and the second type of UE are allowed to access the cell. Or, if the MIB lacks bits of the common-frequency reselection identifier configured for the second type UE and/or reserved bits of the MIB, the UE receives such MIB, and it may be considered that the base station indicates that both the first type UE and the second type UE are allowed to access the cell.

Therefore, by adopting the mode, the 9 kinds of access control information which are necessary to be indicated by the first-class UE and the second-class UE are indicated by using different bit values of the 3 joint coding bits and the state value of whether the 3 joint coding bits are missing in the MIB, and the method has the characteristics of simple implementation and strong compatibility with the related technology.

In one embodiment, the 8 different bit values of the 3 bits indicate restricted access control information of the first type of UE and the second type of UE. And the limited access control information of the first type of UE and the second type of UE indicates whether the first type of UE and the second type of UE are allowed to access the local cell and reselect partial scenes in the same-frequency adjacent cell.

For example, the restricted access control information of the first type of UE and the second type of UE at least excludes at least one scenario of whether the first type of UE and the second type of UE allow access to the local cell and reselect to the co-frequency neighboring cell.

In one embodiment, the restricted access control information is access control information excluding a restricted access scenario.

For example, the restricted access scenario may include: the second type of UE is forbidden to access the local cell and the first type of UE is allowed to access the local cell.

Here, the second type of UE is prohibited from accessing the local cell, and the first type of UE is allowed to access the local cell, which may be further divided into:

the second type of UE is forbidden to access the local cell, the second type of UE is allowed to reselect the same-frequency adjacent cell, and the first type of UE is allowed to access the local cell;

and/or the presence of a gas in the gas,

and the second type of UE is forbidden to access the local cell, the second type of UE is forbidden to reselect the same-frequency adjacent cell, and the first type of UE is allowed to access the local cell.

In another embodiment, the restricted access scenario may include: one of the first type of UE and the second type of UE supports the reselection to the same-frequency adjacent cell, and the other one does not support the reselection to the same-frequency adjacent cell.

One of the first type of UE and the second type of UE supports reselection to the same-frequency adjacent cell, and the other one does not support reselection to the same-frequency adjacent cell; and/or the first type of UE supports the reselection to the same-frequency adjacent cell, and the second type of UE does not support the reselection to the same-frequency adjacent cell.

In one embodiment, the joint coding of 3 bits, the 3 bits for the joint coding are respectively set as: the first bit, the second bit and the third bit are then jointly coded and indicated by the following rules:

when the first bit indicates that the first type of UE and the second type of UE are forbidden to access the cell, the remaining two bits are respectively used for indicating whether the first type of UE is allowed to reselect the same-frequency adjacent cell; and whether the second type of UE is allowed to reselect the same-frequency adjacent cell;

or,

when the first bit indicates that the second type of UE is allowed to access the local cell, one bit of the remaining two bits is used for indicating whether the first type of UE is allowed to access the local cell, and the other bit of the remaining two bits is used for indicating that the first type of UE is allowed to reselect the co-frequency neighbor cell.

Exemplarily, referring to fig. 4, the value of the first bit is "0", which is equivalent to indicating that both the first type UE and the second type UE are prohibited from accessing the cell; the second bit and the third bit are used to indicate whether the first type UE and the second type UE allow reselection to the same-frequency neighboring cell, respectively.

The value of the first bit is "1", which is equivalent to indicating that the second type of UE is allowed to access the cell, because the second type of UE is allowed to access the cell, the second type of UE will preferentially access the cell, and it is not necessary for the second type of UE to support the identifier of the co-frequency neighboring cell, so the second bit and the third bit can be used to indicate whether the first type of UE is allowed to access the cell and whether the first type of UE is allowed to reselect the co-frequency neighboring cell.

If the first type of UE is assumed to be a Redcap UE, the second type of UE is a non-Redcap UE, that is, the second type of UE is any UE other than the Redcap UE. In fig. 4, "0/1" indicates that the value of the corresponding bit may be "0" and "1", and specifically, "0" or "1" may be determined according to factors in the load ratios and/or radio conditions of the local cell and the co-frequency neighbor cells.

In one embodiment, the MIB comprises:

the cell barring identity of the second type of UE is configured to indicate that the second type of UE is allowed or barred to access the cell;

the co-frequency reselection identifier of the second type of UE is configured to indicate that the second type of UE is allowed or forbidden to reselect the co-frequency neighbor cell of the cell;

when the cell forbidden identifier of the second type UE indicates that the second type UE is allowed to access the cell, one bit of the same-frequency reselection identifier of the second type UE and the reserved bit of the MIB indicates whether the first type UE is allowed to access the cell; and the same-frequency reselection identifier of the second type UE and the other bit of the reserved bits of the MIB indicate whether the first type is allowed to reselect the same-frequency adjacent cell;

or,

when the cell forbidden identifier of the second type UE indicates that the second type UE is forbidden to access the cell, the reserved bit configured by the MIB indicates that the first type UE is allowed to access the cell; the same-frequency reselection identifier of the second type UE indicates whether the second type UE is allowed to reselect the same-frequency neighbor cell;

or,

when the cell forbidden identifier of the second type UE indicates that the second type UE is forbidden to access the cell, the reserved bit configured by the MIB indicates that the first type UE is forbidden to access the cell; the same-frequency reselection identifier of the second type UE indicates whether the second type UE is allowed to reselect the same-frequency neighbor cell; the MIB is configured to indicate at least one of information bits of preset information to indicate whether the first type of UE is allowed to reselect to a same-frequency neighbor cell;

or,

when the cell forbidden identifier of the second type of UE indicates that the second type of UE is forbidden to access the cell, the same-frequency reselection identifier of the second type of UE indicates whether the second type of UE is allowed to reselect the same-frequency adjacent cell; the MIB is configured to indicate at least one of information bits of preset information to indicate whether the first-class UE is allowed to access to the cell;

or,

when the cell forbidden identifier of the second type of UE indicates that the second type of UE is forbidden to access the cell, the same-frequency reselection identifier of the second type of UE indicates whether the second type of UE is allowed to reselect the same-frequency adjacent cell; the MIB is configured to indicate at least one of information bits of preset information, indicate whether the first-class UE is allowed to access to the local cell or not, and support the first-class UE to reselect to a same-frequency neighbor cell.

And whether the second type of UE is allowed to access the local cell. If the second type of UE is allowed to access the cell, the access control information for indicating the first type of UE may be idle by using the bit corresponding to the co-frequency reselection identifier of the second type of UE. If the second type of UE is prohibited to access the local cell, other control information and/or resource configuration information and the like carried in the MIB for indicating that the first type of UE accesses the local cell are invalid, which is equivalent to bits indicating the preset information becoming invalid bits. In the embodiment of the disclosure, the conditions that the second type of UE is forbidden and allowed to access the cell are fully utilized, and the same-frequency reselection identifier and/or the invalid bit of the second type of UE are repeatedly utilized to skillfully indicate whether the first type of UE is allowed to access the cell and/or whether the first type of UE is allowed to reselect to a same-frequency neighboring cell.

According to the technical scheme provided by the embodiment of the disclosure, the access control information of the first type UE is successfully introduced into the MIB without introducing extension bits into the MIB and modifying the information format of the MIB, and the method has the characteristics of strong compatibility with related technologies and low bit overhead of the MIB.

In one embodiment, the preset information includes at least one of:

configuring configuration Information of a Physical Downlink Control Channel (PDCCH) of a System message Block (SIB 1), namely, PDCCH-ConfigSIB 1;

subcarrier spacing common configuration information, namely subcarriersspacingmmon;

demodulating reference signal DRMS type A Position information, namely dmrs-type A-Position;

the subcarrier spacing offset of the synchronization signal block, ssb-subarrieronoffset.

Of course, the above is only an example of the preset information, and in a specific implementation, the invalid bit is configured as the preset information to be indicated, which is not limited to any one of the above examples, and may be any information related to access in the MIB.

In some embodiments, the MIB comprises:

a sync signal block index and a sync signal block index-subcarrier interval information field, i.e., an ssb-subarrieraffset information field.

Wherein, the synchronizing signal block index and synchronizing signal block index-subcarrier interval information field has reserved bits when indicating subcarrier offset smaller than preset frequency;

the reserved bit is used for indicating whether the first type of UE is allowed to access the local cell and/or indicating whether the first type of UE is allowed to reselect the co-frequency neighbor cell.

The preset frequency may be 6 ghz. The SSB-subarrieronoffset information field may have 7 bits in total, wherein the SSB-subarrieronoffset information field requires only 5 bits to indicate the Kss when indicating the SSB index and the subcarrier offset (Kss), and thus 2 bits remain. In the embodiment of the present disclosure, the remaining 2 bits (i.e., the reserved bits in the ssb-subcarrieronoffset information field) may be respectively used as the cell barring identity and the intra-frequency reselection identity of the first type of UE, so as to respectively indicate whether to allow the first type of UE to access the local cell and whether to allow the first type of UE to reselect to an intra-frequency neighboring cell.

In one embodiment, the MIB comprises:

a sync signal block index and a sync signal block index-subcarrier spacing information field;

and when the synchronization signal block index and the synchronization signal block index-subcarrier interval information field indicate subcarrier offset not less than preset frequency, the value of the subcarrier offset has a corresponding relation with the access control information of the first type of UE.

If the ssb-subanticrierffset information field is indicating a carrier frequency greater than 6Ghz, 3 of the 7 bits need to indicate the index of the synchronization signal block (ssb); the remaining 4 bits need to indicate the subcarrier offset (Kss) of the broadcast synchronization signal block. Thus, in this scenario, the ssb-SubcarrierOffset information field is consumed.

In the embodiment of the present disclosure, an implicit indication manner is adopted at this time to establish a corresponding relationship between the Kss and the access control information of the first type UE. Therefore, by setting the Kss to a specific value, on one hand, the subcarrier offset of the UE is determined, and on the other hand, whether the first type UE is allowed to access the local cell or whether the first type UE supports reselection to the co-frequency neighboring cell is determined through the correspondence.

Exemplarily, the second UE prohibits access to the local cell;

the first value of the subcarrier offset indicates that the first type of UE is allowed to access the cell;

or,

and the second value of the subcarrier offset indicates that the first type of UE is forbidden to access the cell.

Here, the second value is different from the first value.

In the embodiment of the present disclosure, the second value and the first value are both 1 or more.

Illustratively, the first value may be {0, 1, 2, … 11}, i.e., the first value is 0 to 11; and the second value may be 12 or from 12 to 15.

In one embodiment, the MIB contains information bits indicating preset information;

at least one of the preset information bits indicates whether the first type of UE is allowed to reselect the co-frequency neighbor cell.

In another embodiment, the MIB ignores information whether the first type of UE is allowed to reselect to a co-frequency neighboring cell, i.e., the MIB does not indicate whether the first type of UE supports reselection to the co-frequency neighboring cell.

In one embodiment, a first portion of the second value of the subcarrier offset indicates that the first type of UE is allowed to reselect to the co-frequency neighboring cell;

or

A second portion of the second value of the subcarrier offset indicates that the first class of UE is allowed to reselect to the co-frequency neighbor cell.

For example, assume that the second value ranges from: 12 to 15; the second value of the first portion may comprise at least 12; the second value of the second portion may be 13 to 15; alternatively, the second value of the first portion may comprise: 12 and 13; the second value of the second portion may be 14 to 15.

In summary, in the embodiment of the present disclosure, the second value may include a plurality of values, and is divided into a first portion and a second portion. The first part and the second part have different corresponding second values.

The second value of the first part not only indicates that the first type UE is forbidden to access the cell, but also indicates whether the first type UE is allowed to reselect to the same-frequency adjacent cell, thus, the indicating bit corresponding to the Kss simultaneously realizes the composite indication of three information, namely subcarrier offset, the first type UE is forbidden to access the cell, and whether the first type UE supports the reselection to the same-frequency adjacent cell, and has the characteristic of small bit cost.

In one embodiment, the second type of UE is allowed to access the local cell; the MIB is configured with a same-frequency reselection identifier for indicating whether the second-type UE supports the reselection to the same-frequency adjacent cell or not, and indicating whether the first-type UE is allowed to access the cell or not.

Since the second type of UE is allowed to access the cell, only the cell forbidden identifier originally configured to the second type of UE by the MIB needs to be used, and the same-frequency reselection identifier originally configured to the second type of UE can be used to indicate whether to allow the first type of UE to access the cell.

In this scenario, whether the first type UE allows to reselect to the co-frequency neighbor cell may be determined by the first type UE, or determined according to a communication protocol, or by using a preset manner (including but not limited to hardcode, hard coding), and the like. See the following embodiments depending on the communication protocol decision. Therefore, whether the first-class UE is allowed to access the local cell or not and whether the first-class UE is allowed to reselect to the same-frequency neighbor cell or not is determined according to the communication protocol or by adopting a preset mode (for example, a hard coding mode), on one hand, the compatibility with the related technology is strong, and on the other hand, the bit overhead and the power consumption of the first-class UE, which are caused by the interaction of the first-class UE and the base station due to the access control information, are reduced.

In one embodiment, in this scenario, whether the first type of UE allows to reselect to the co-frequency neighboring cell may be determined according to a default configuration, for example, the first type of UE is allowed to reselect to the co-frequency neighboring cell by default, or the first type of UE is prohibited from reselecting to the co-frequency neighboring cell by default. In summary, whether the UE of the first type is allowed to reselect to the co-frequency neighbor cell at this time may not be indicated in the MIB.

In one embodiment, the 110 may include:

and determining whether the first-class UE supports reselection to the same-frequency adjacent cell or not according to a protocol.

In one embodiment, the determining whether the first type of UE supports reselection to a co-frequency neighbor cell according to a protocol includes: determining to forbid the first type of UE from the local cell according to a protocol, and allowing the first type of UE to reselect a co-frequency cell; and/or determining to prohibit the first type of UE from reselecting to a same frequency cell according to a protocol.

In one embodiment, the determining whether the first type of UE supports reselection to a co-frequency neighbor cell according to a protocol includes:

and determining whether to allow the first type of UE to reselect the same-frequency adjacent cell according to the protocol, wherein the first type of UE is forbidden to access the cell, and the second type of UE is forbidden to access the same-frequency adjacent cell according to the same-frequency reselection identifier of the second type of UE.

The determining, according to the co-frequency reselection identity of the second type of UE when the second type of UE is prohibited from accessing the local cell, that the first type of UE is allowed to reselect the co-frequency neighboring cell includes:

in response to the same-frequency reselection identification indication and the following strategy of the second type UE when the second type UE is forbidden to access the cell, determining that the same-frequency reselection identification of the first type UE and the same-frequency reselection identification of the second type UE have the same value;

or,

and in response to the same-frequency reselection identification indication and the reverse strategy of the second type UE when the second type UE is forbidden to access the cell, determining that the value of the same-frequency reselection identification of the first type UE is opposite to that of the same-frequency reselection identification of the second type UE.

If the following strategy is adopted, whether the first type of UE allows to reselect the same-frequency adjacent cell at the moment is consistent with the second type of UE, so that the first type of UE and the second type of UE are allowed to reselect the same-frequency cell possibly, and the following strategy is suitable for the condition that the cell load rate of the same-frequency adjacent cell is low.

If a reverse strategy is adopted, one UE of the first type UE and the second type UE is allowed to reselect to the same-frequency adjacent cell, and the reverse strategy is suitable for the condition that the load rate of the same-frequency adjacent cell is high.

By adopting the mode, the same as the same-frequency reselection identification originally configured for the second type of UE in the MIB, and whether the first type of UE and the second type of UE support the reselection to the same-frequency adjacent cells or not is indicated, so that the method has the characteristics of small bit overhead and strong indication capability.

As shown in fig. 5, an embodiment of the present disclosure provides an access control information processing apparatus, including:

a determining module 510 configured to determine access control information of a first type of user equipment UE;

wherein the access control information indicates at least one of:

forbidding the first type UE to access the cell;

allowing the first type of UE to access the cell;

In one embodiment, the determining module 510 may be a program module; the program module, when executed by the processor, determines access control information for a first type of UE. The access control information relates to contents including but not limited to: whether the first type UE is allowed to access to the local cell and/or whether the first type UE is allowed to reselect to a co-frequency adjacent cell of the local cell.

In another embodiment, the determining module 510 may be a soft-hard combining module; the soft and hard combining module includes but is not limited to: a programmable array; the programmable array includes, but is not limited to: complex programmable arrays and/or field programmable arrays.

In yet another embodiment, the determining module 510 includes, but is not limited to: a pure hardware module; including but not limited to application specific integrated circuits.

In one embodiment, the determining module 510 is configured to transmit a master information block, MIB, carrying access control information of the first type of UE.

In one embodiment, the MIB comprises:

the cell forbidden identifier of the first type UE is used for indicating that the first type UE is allowed or forbidden to access the cell;

and/or the presence of a gas in the gas,

and the same-frequency reselection identifier of the first type of UE is used for indicating that the first type of UE is allowed or forbidden to reselect the same-frequency neighbor cell.

In one embodiment, the cell forbidden identifier of the first type UE is a reserved bit of the MIB, and the co-frequency reselection identifier of the first type UE is an extended bit; or the cell forbidden identifier of the first type of UE is an extension bit of the MIB, and the same-frequency reselection identifier of the first type of UE is a reserved bit.

In one embodiment, the MIB comprises: jointly encoding the bits; wherein different bit values of the joint coding bit respectively indicate whether the first type of UE and the second type of UE allow access to the cell; and whether the first type of UE and the second type of UE allow to reselect the same-frequency neighbor cell of the local cell or not.

In one embodiment, when at least one bit of the 3 bits is missing in the MIB, the MIB indicates: whether the first type of UE and the second type of UE allow to access the local cell and reselect to at least one scene in the same-frequency adjacent cell. Illustratively, when at least one of the 3 bits is missing in the MIB, the MIB indicates a scenario that allows the first type UE to access the local cell and allows the second type UE to access the local cell.

In one embodiment, the 3 bits are a first bit, a second bit and a third bit; different bit values of the 3 bits are used for indicating the access control information of the first type of UE and the second type of UE after being limited; and the limited access control information of the first type of UE and the second type of UE indicates whether the first type of UE and the second type of UE are allowed to access the local cell and reselect partial scenes in the same-frequency adjacent cell. For example, the restricted access control information of the first type of UE and the second type of UE at least excludes a scenario in which whether the first type of UE and the second type of UE are allowed to access the local cell and reselect to the co-frequency neighboring cell.

In an embodiment, the restricted access control information of the first type of UE and the second type of UE excludes a scenario in which the second type of UE is prohibited from accessing the local cell and the first type of UE is allowed to access the local cell.

In another embodiment, the restricted access control information of the first type of UE and the second type of UE may exclude a scenario that neither the first type of UE nor the second type of UE supports reselection to the co-frequency neighboring cell. For example, the restricted access control information of the first type of UE and the second type of UE may exclude: the first type of UE and the second type of UE are forbidden to access the cell, and the first type of UE and the second type of UE do not support the scene of reselecting the same-frequency adjacent cell.

In one embodiment, the MIB comprises:

configured to indicate permission or prohibition of the second type of UE to reselect to a co-frequency neighbor cell of the local cell;

or,

In one embodiment, the preset information includes at least one of:

configuring the configuration information of a Physical Downlink Control Channel (PDCCH) of an SIB 1;

subcarrier spacing common configuration information;

demodulating reference signal DRMS type A position information;

the subcarrier spacing offset of the synchronization signal block.

In one embodiment, the MIB comprises: a sync signal block index and a sync signal block index-subcarrier spacing information field;

In one embodiment, the MIB comprises:

In one embodiment, the second UE prohibits access to the local cell;

or,

In one embodiment, the second UE prohibits access to the local cell;

a first portion of the second value of the subcarrier offset indicates that the first class of UE is allowed to reselect to the co-frequency neighbor cell;

or

In one embodiment, the second type of UE is allowed to access the local cell;

the MIB is configured with a same-frequency reselection identifier for indicating whether the second-type UE supports the reselection to the same-frequency adjacent cell or not, and indicating whether the first-type UE is allowed to access the cell or not.

In one embodiment, the determining module 510 is configured to determine whether the first type of UE supports reselection to co-frequency neighbor cells according to a protocol.

In an embodiment, the determining module 510 is configured to determine, according to a protocol, to prohibit the first type of UE from the local cell, and allow the first type of UE to reselect to an intra-frequency cell; or determining to prohibit the first type of UE from reselecting to the same-frequency cell according to a protocol.

In an embodiment, the determining module 510 is configured to determine to prohibit the first type of UE from accessing the local cell according to the protocol, and determine whether to allow the first type of UE to reselect the co-frequency neighboring cell according to a co-frequency reselection identity of the second type of UE when the second type of UE is prohibited from accessing the local cell.

In an embodiment, the determining module 510 is configured to determine that the value of the co-frequency reselection identity of the first type UE is the same as the value of the co-frequency reselection identity of the second type UE in response to the indication of the co-frequency reselection identity of the second type UE and a follow-up policy when the second type UE is prohibited from accessing the local cell; or, in response to the indication of the co-frequency reselection identifier of the second type of UE and a reverse policy when the second type of UE is prohibited from accessing the cell, determining that the value of the co-frequency reselection identifier of the first type of UE is opposite to that of the co-frequency reselection identifier of the second type of UE.

In the embodiment of the present disclosure, the MIB includes (i.e., carries) information for controlling UE access, and in the embodiment of the present disclosure, the information for controlling UE access may be referred to as access control information.

The access control information may include: and controlling the UE to access to the control information of the local cell and/or controlling the UE to access to the control information of the adjacent cell. Neighbor cells here include, but are not limited to: the same frequency adjacent cell of the cell and/or the different frequency adjacent cell of the cell.

For example, a cell barring (cellbar) identifier already exists in the MIB to control whether the user is barred from accessing the cell.

Meanwhile, there is also an intra freq reselection identifier (intra freq reselection) in the MIB, which is used to control whether the UE is allowed to perform inter-frequency neighbor cell reselection when the UE is prohibited from accessing the cell. The co-frequency neighbor cells here are: and the adjacent cells of the cell use the cells with the same frequency points as the cell.

That is, if the intra-frequency reselection flag indicates that the UE is allowed to reselect the neighboring cell of the local cell, the UE is allowed to continue reselecting another cell of the same frequency, otherwise, the UE is not allowed to reselect another cell of the same frequency.

The MIB has one reserved bit (bit).

With the development of wireless communication technology, Redcap UE proposes a Reduced capability (Redcap) UE with low power consumption, or simply an NR-lite terminal or a Redcap terminal. The equipment is similar to the equipment of the internet of things in Long Term Evolution (LTE). The Redcap UE may be referred to as a specific UE, which is one of the aforementioned UEs of the first type.

Redcap UE has one or more of the following characteristics: low cost, low complexity, support a degree of coverage enhancement and power savings.

After the introduction of the Redcap UE, the cell reselection processing function also needs to be considered for the cell access processing of the Redcap UE and after the Redcap UE is forbidden to enter the cell.

A Radio Access Network (RAN) provides a cell barring identity and/or an intra-frequency reselection identity specific to a specific UE.

As an embodiment, the specific UE is a UE other than a UE conventionally used for terminal, such as a Redcap UE.

For example, the RAN provides a specific UE with a cell barring identity and/or an on-frequency reselection identity provided in the MIB.

One embodiment is as follows: cell barring identity for a specific UE. For example, the cell barring identity of a particular UE may be referred to as: cellBarred _ Redcap identification. The cell barring identity of the specific UE may be used to indicate whether the specific UE is barred in the cell.

One embodiment is as follows: intra freqreselection (intra reselection) identification for a particular UE. For example, the intra-frequency reselection identity of a specific UE may be referred to as: intrafeqReselection _ Redcap identification. The intrafreq reselection _ Redcap id may be configured to indicate whether the UE is allowed to perform intra-frequency cell reselection when the UE is prohibited from accessing the local cell.

In one embodiment, one bit is added to the MIB. The RAN provides a cell forbidden identifier and/or an intra-frequency reselection identifier for a specific UE in the MIB, and indicates whether the general UE and the specific UE allow access to the local cell and/or allow reselection to an intra-frequency neighboring cell respectively by using a cell reselection identifier of the general UE (including but not limited to NR UE), the intra-frequency reselection identifier, and a reserved bit currently contained in the MIB to perform joint coding.

One embodiment may be as follows:

the reserved bit and the newly added bit are used for determining whether the specific UE is allowed to access the local cell or not and whether the specific UE is allowed to be reselected to the same-frequency adjacent cell of the local cell or not. The newly added bit is the extension bit.

Another embodiment may be as follows:

3 bits are jointly coded, and these 3 bits can be called joint coded bits, and have 8 bit values, and 8 cases can be identified, for example but not limited to the following examples:

that is, the bit values "000" to "111" of these 3 bits indicate the following scenarios, respectively:

NR UE is forbidden to access the cell, NR UE is allowed to reselect to a same-frequency neighbor cell, and Redcap UE is allowed to access the cell;

NR UE is forbidden to access the cell, NR UE is forbidden to reselect to a same-frequency neighbor cell, and Redcap UE is allowed to access the cell;

NR UE allows access to the cell, Redcap UE prohibits access to the cell, and the Redcap UE is allowed to reselect to the same-frequency adjacent cell;

NR UE allows access to the cell, Redcap UE prohibits access to the cell, and Redcap UE is prohibited to reselect to the same-frequency adjacent cell;

NR UE is forbidden to access the local cell, NR UE is allowed to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is allowed to reselect to the same-frequency adjacent cell;

NR UE is forbidden to access the local cell, NR UE is allowed to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is forbidden to reselect to the same-frequency adjacent cell;

NR UE is forbidden to access the local cell, NR UE is forbidden to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is allowed to reselect to the same-frequency adjacent cell;

NR UE is forbidden to access the local cell, NR UE is forbidden to reselect to the same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is forbidden to reselect to the same-frequency adjacent cell.

Additionally, for NR UEs allowed to access the own cell and/or Redcap UEs allowed to access the own cell, a state where at least one bit does not exist in the MIB is used for indication. That is, if the bit does not exist, the RAN UE is instructed to allow access to the local cell and/or the Redcap UE is allowed to access the local cell. The unconfigured or non-existent bits are: one of the aforementioned 3 jointly coded bits. For example, reserved bits in the MIB are configured as optional bits. The optional bit is used to indicate that Redcap is allowed to access the local cell (i.e. not bar), i.e. if the reserved bit is not present in the MIB, the identifier NR UE is allowed to access the local cell and/or the Redcap UE is allowed to access the local cell.

For another example, the cell barring identity and the reserved bit configuration existing in the MIB are both optional bits. The optional bits are respectively used for allowing the NR UE to access the cell and allowing the Redcap UE to access the cell, namely, the two bits do not exist in the MIB, and the identifier is that the NR UE allows the NR UE to access the cell and/or the Redcap UE is allowed to access the cell.

In one embodiment, the RAN provides a specific cell barring (cellbar) identifier and/or intra-frequency reselection identifier for a specific UE in the MIB by jointly encoding the cell barring (cellbar) identifier, the intra-frequency reselection identifier and/or reserved bits of the MIB of a normal (e.g., NR UE) UE.

In the joint coding process, part of the configuration is restricted, for example, the situation that the eMB UE and the Redcap UE are prohibited to access the cell at the same time is restricted. The eMBB UE is one of the NR UEs described above. Thus, there are 3 bits in the MIB for joint coding.

When joint coding is performed using these 3 bits, two cases can be distinguished.

When one bit of the 3 bits has a value indicating that the cell forbids the access of the Redcap UE and the NR UE, the remaining two bits are respectively used for indicating whether the Redcap UE is allowed to reselect the same-frequency neighbor cell; and whether the NR UE is allowed to reselect to the co-frequency neighbor cell; or, when one bit of the 3 bits has a bit indicating that the NR UE is allowed to access the local cell, one bit of the remaining two bits is used to indicate whether the first type UE is allowed to access the local cell, and the other bit of the remaining two bits is used to indicate that the Redcap UE is allowed to reselect to the co-frequency neighbor cell.

In table 1: "0" indicates that the access to the cell is forbidden, and "1" indicates that the access to the cell is allowed; "1" indicates support for reselection to co-frequency neighbor cells; the "0" identification does not support reselection to co-frequency neighbor cells.

TABLE 1

In the above table "-" means no attention or that the indication is not present in the MIB.

For the access situation of NR UE and Redcap UE in the local cell and the situation of whether or not reselection to the co-frequency neighboring cell is supported, the following scenarios may be included:

scene 5: NR UE is allowed to access the local cell, no Redcap UE is supported to reselect to the same-frequency neighbor cell, and Redcap UE is prohibited to access the local cell scenario 6: NR UE is forbidden to access the local cell, NR UE is supported to reselect to a same-frequency adjacent cell, Redcap UE is forbidden to access the local cell, and Redcap UE is supported to reselect to the same-frequency adjacent cell;

In the scenario 9, considering that the usage of the scenario 2 and the scenario 3 is little or none, when the joint coding indication is performed by using 3 bits, the scenarios of the scenario 2 and the scenario 3 can be ignored. Namely, the limitation of the access control configuration of the two types of UE is performed, the reasonable combination of the expression is reduced, and the purpose of sufficient indication by using 3 bits is achieved.

In one embodiment, the RAN provides the specific UE with reserved bits (spare bits) and/or invalid bits in the MIB as the cell barring identity and/or the on-frequency reselection identity of the specific UE.

One useful embodiment: when the cell barring identity of the NR UE indicates that the NR UE is barred from accessing the cell, and when the specific UE is also barred from accessing the cell, the current MIB indicates that pdcch-ConfigSIB1, subcarriersspacingmon, dmrs-TypeA-Position, ssb-subcarrieronoffset, etc. are not actually used, and a bit indicating such preset information may be referred to as an invalid bit. Therefore, any bit in the invalid bits can be used as the cell forbidden identifier and/or the intra-frequency reselection identifier of the specific UE.

Another useful embodiment: when the cell forbidden identifier of the NR UE indicates that the NR UE is forbidden to access the cell and the specific UE is also indicated to be forbidden to access the cell, the pdcch-ConfigSIB1, subcarrirSpacingCommon, dmrs-TypeA-Position, ssb-subcarrierOffset and the like in the current MIB have no practical use, and any 1 bit can be defined as the specific same-frequency reselection identifier of the specific UE; and one reserved bit using the current MIB can be used as a cell barring identity for a particular UE.

Yet another useful embodiment: when the cell forbidden identifier of the NR UE indicates that the NR UE is allowed to access the cell, the RAN may be configured to serve as the cell forbidden identifier and/or the intra-frequency reselection identifier of the specific UE, by using the intra-frequency reselection identifier originally used for the NR UE in the MIB.

The cell forbidden identifier existing in the MIB is assumed to indicate whether NR and other non-specific UE are allowed to access the cell; the reserved bit is used as a cell barring identity of the specific UE to indicate whether the specific UE is allowed to access the cell, and the indication of the MIB on the access control information of the specific UE and the non-specific UE may be at least one of the following:

TABLE 2

In table 2, x is the invalid bit, where x1 and x2 are different values of the invalid bit.

In one embodiment, the RAN provides a specific UE with a bit already occupied in the MIB as a cell barring identity and/or an on-frequency reselection identity.

In one useful implementation: the use cases of the SSB index and the SSB-subanticrierffset information fields in the MIB can be shown in table 3:

TABLE 3

In view of this, when the carrier frequency f is less than 6GHz, 1 bit of the reserved 2 bits may be multiplexed as a cell barring identity of a Recap UE, and the other bit may be used as an intra-frequency reselection identity of the Recap UE.

And when the carrier frequency is greater than 6GHz, the original cell forbidden identifier in the MIB is used for indicating whether the UE which is not specified by the Redcap UE is forbidden to access the cell.

And if the non-specific UE is forbidden to access the cell, the original same-frequency reselection identification in the MIB is used for indicating whether the non-specific UE is allowed to reselect the same-frequency adjacent cell. Using the value range of Kss to indicate whether the Redcap UE is forbidden;

for example, when the Kss value range is {0, 1, 2, … 11}, it indicates that the Redcap UE is not prohibited to access the cell, i.e., the Redcap UE is allowed to access the cell;

when the value range of the Kss does not belong to {0, 1, 2, … 11}, the UE is prohibited from accessing the cell. At this time, the MIB may be used to indicate whether the Redcap UE supports reselection to the same-frequency neighbor cell, except for the cell barring identity, the same-frequency reselection identity, and Kss of the specific UE, e.g., a bit originally used for PDCCH-ConfigSIB1 to indicate whether the Redcap UE supports reselection to the same-frequency neighbor cell.

Implicitly, using the Kss value not belonging to {0, 1, 2, … 11} indicates that the Redcap UE is prohibited from being used by the cell, for example, after 12 Kss value is that the Redcap UE is prohibited from being used by the cell, the support is to make the Redcap UE be supported to reselect to the same-frequency neighbor cell, for example, Kss value of 13 may be considered to indicate that the Redcap UE is supported to reselect to the same-frequency neighbor cell.

Aiming at the permission of non-specific UE to access the cell, the original same-frequency reselection identification in the MIB is used for indicating whether the Redcap UE is forbidden to access the cell. And if the same-frequency reselection identifier is available, the identifier can be used for indicating that the Redcap UE is allowed to access the cell or is forbidden to access the cell.

Whether the reselection to the same-frequency neighbor cell is supported by the Redcap UE can be ignored.

In the embodiment of the present disclosure, the non-specific UE is the aforementioned second type UE.

In one embodiment, whether a specific UE supports reselection to a co-frequency neighbor cell may be agreed in advance according to a protocol;

the protocol can stipulate in advance that the same-frequency cell reselection is allowed under the condition that the specific UE is forbidden to be accessed by the cell;

as an example; the protocol can stipulate in advance that the common-frequency cell reselection is not allowed under the condition that the specific UE is forbidden to access the cell;

as an example; the protocol can stipulate in advance whether the specific UE allows the same-frequency cell reselection following under the condition that the specific UE is forbidden to access the cell and whether the common NR allows the same-frequency cell reselection under the condition that the common NR is accessed by the cell;

as an example; the protocol may stipulate in advance whether to allow intra-frequency cell reselection when the specific UE is accessed by the cell, which is contrary to the behavior of whether to allow intra-frequency cell reselection when the normal NR is bar.

The embodiment of the disclosure provides a communication device, which includes a processor, a transceiver, a memory, and an executable program stored on the memory and capable of being run by the processor, wherein the access control information processing method provided by any of the foregoing technical solutions is executed when the executable program is run by the processor.

The communication device may be the aforementioned base station or UE.

The processor may include, among other things, various types of storage media, which are non-transitory computer storage media capable of continuing to remember the information stored thereon after a power loss to the communication device. Here, the communication apparatus includes a base station or a user equipment.

The processor may be connected to the memory via a bus or the like for reading an executable program stored on the memory, e.g. at least one of the methods as shown in fig. 2 to 4.

The disclosed embodiments provide a computer storage medium having an executable program stored therein; the executable program, when executed by a processor, is capable of implementing the method of any of the aspects of the first or second aspects, for example, at least one of the methods shown in fig. 2 to 4.
