Description

Access processing method, information processing method, configuration sending method and device

Technical Field

The present application belongs to the field of communication technology, and specifically relates to an access processing method, an information processing method, a configuration sending method and a device.

Background Art

With the development of communication technology, more and more terminals are connected to the communication system, and multiple types of terminals can be supported, such as some new terminals or legacy terminals (legacy UE). In some related technologies, when a terminal accesses the network, the main technical means used is that different types of terminals are directly selected for access. In practice, it is found that if all spectrum resources are directly selected for access by the terminal, some spectrum resources may not be successfully accessed, or some spectrum resources only allow specific terminals to access. Therefore, if all spectrum resources are directly selected for access by the terminal, the terminal access performance will be relatively poor.

The access processing method, information processing method, configuration sending method and device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

Please refer to FIG. 2, which is a flow chart of an access processing method provided in an embodiment of the present application. As shown in FIG. 2, the method includes the following steps:

Step 201: A first terminal obtains target information, where the target information is associated with a target spectrum resource, and a spectrum resource bandwidth of the target spectrum resource satisfies a first preset condition.

The first terminal may be a common terminal, or may be a traditional terminal (legacy UE), a legacy terminal, an old version terminal, etc., and there is no specific limitation on this.

The above-mentioned target information may be information sent by the receiving network side, or the above-mentioned target information may be information generated or determined by the first terminal.

The target information may be associated with the target spectrum resource in such a way that the target information is information received from the target spectrum resource, or the target information is information related to a frequency domain parameter of the target spectrum information.

The target spectrum resource may be a dedicated spectrum resource, or the target spectrum resource may be a narrowband spectrum resource, such as a spectrum resource with a bandwidth within 3-5 MHz (such as 3 MHz or 3.6 MHz).

The first preset condition mentioned above may be a condition defined by a protocol or configured on the network side.

The spectrum resource bandwidth of the target spectrum resource satisfies the first preset condition, which may be that the spectrum resource bandwidth of the target spectrum resource is within a preset bandwidth range, or that the spectrum resource bandwidth of the target spectrum resource is a preset bandwidth size.

Step 202: The first terminal determines, based on the target information, whether the first terminal accesses or is allowed to access a cell that uses the target spectrum resources.

Step 202 may include at least one of the following:

The first terminal determines, according to the target information, whether the first terminal accesses a cell that uses the target spectrum resources;

The first terminal determines, according to the target information, whether the first terminal is allowed to access a cell that uses the target spectrum resources;

The first terminal determines, based on the target information, whether the first terminal is allowed to access a cell that uses the target spectrum resources, and determines whether the first terminal accesses a cell that uses the target spectrum resources.

In step 202, it may be determined whether the first terminal accesses or is allowed to access a cell using the target spectrum resources according to the indication content of the target information or the fields included in the target information.

The above-mentioned determining whether the first terminal is allowed to access the cell using the target spectrum resources may be determining whether the cell using the target spectrum resources allows the first terminal to access and establish a wireless resource connection.

The above-mentioned determining whether the first terminal accesses the cell adopting the target spectrum resources may be determining whether the first terminal accesses the cell adopting the target spectrum resources and establishes a wireless resource connection.

The cell using the target spectrum resources may also be referred to as a cell or network deployed on the target spectrum resources.

In an embodiment of the present application, since whether the first terminal accesses or is allowed to access a cell that uses the target spectrum resources is determined based on the target information, it can be achieved that when it is determined that the first terminal does not access or is not allowed to access a cell that uses the target spectrum resources, access is not performed, thereby reducing network congestion of the target spectrum resources, or reducing interference with the target spectrum resources, or reducing power consumption of the terminal, thereby improving the access performance of the terminal.

As an optional implementation manner, the first preset condition includes at least one of the following:

The spectrum resource bandwidth is less than or equal to the first preset bandwidth;

The spectrum resource bandwidth is greater than or equal to a second preset bandwidth, and the second preset bandwidth is less than the first preset bandwidth;

The spectrum resource bandwidth is different from the multiple bandwidth sizes defined in the protocol;

The spectrum resource bandwidth is different from the bandwidth combination size. The bandwidth combination size is a bandwidth size obtained by adding any N bandwidth sizes among multiple bandwidth sizes defined in the protocol, where N is an integer greater than 1.

The first preset bandwidth may include: a channel bandwidth of 5 MHz, or a transmission bandwidth of 5 MHz.

It should be noted that, in the embodiments of the present application, the first preset bandwidth is not limited to 5 MHz. For example, in some embodiments, the first preset bandwidth is other bandwidth sizes defined by the protocol, such as 10 MHz.

The second preset bandwidth may include: a channel bandwidth of 3 MHz, or a transmission bandwidth of 3 MHz.

It should be noted that in the embodiments of the present application, the second preset bandwidth is not limited to 3 MHz. For example, in some embodiments, the first preset bandwidth is other bandwidth sizes defined by the protocol, such as 2.5 MHz or 2 MHz.

The multiple bandwidth sizes defined in the above-mentioned protocol may be multiple bandwidth sizes currently defined in the protocol, and the spectrum resource bandwidth of the above-mentioned target spectrum resource may be a bandwidth newly defined in the protocol.

In some embodiments, the multiple bandwidth sizes defined in the above-mentioned protocol may be multiple bandwidth sizes that have been defined before the preset condition is defined in the protocol; or, the multiple bandwidth sizes defined in the protocol may be multiple bandwidth sizes supported by the first terminal defined in the protocol; or, the multiple bandwidth sizes defined in the protocol may be multiples of 5 MHz.

For example, the spectrum resource bandwidth of the target spectrum resource does not belong to the channel bandwidth size currently defined in the protocol, that is, the size of the target spectrum resource is not 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, or 100 MHz.

For another example, the spectrum resource bandwidth of the target spectrum resource cannot be obtained by adding any multiple values of the channel bandwidth sizes currently defined by the protocol, such as the size of the target spectrum resource is 6, 7, 11, 12, 13, 33 MHz.

In some implementations, the bandwidth size may include:

Channel bandwidth size, or transmission bandwidth size.

In the above implementation manner, the first terminal can execute a judgment on whether to access or be allowed to access a cell using the target spectrum resources for spectrum resources that meet at least one of the above items, thereby reducing network congestion of these spectrum resources, or reducing interference of these spectrum resources, or reducing power consumption of the terminal.

As an optional implementation manner, the channel bandwidth of the first terminal does not support the spectrum resource bandwidth of the target spectrum resource.

The channel bandwidth of the first terminal does not support the spectrum resource bandwidth of the target spectrum resource, which may be that the terminal channel bandwidth (UE channel bandwidth) of the first terminal does not support the spectrum resource bandwidth of the target spectrum resource for frequency range (FR) 1 or frequency range 2 (FR2).

In this implementation, it is possible to execute a judgment on whether the first terminal accesses or is allowed to access a cell that uses the target spectrum resources when the channel bandwidth of the first terminal does not support the spectrum resource bandwidth of the target spectrum resources, thereby reducing network congestion of the target spectrum resources, or reducing interference with the target spectrum resources, or reducing power consumption of the terminal.

As an optional implementation manner, the target information includes at least one of the following:

A Master Information Block (MIB) received at the target spectrum resource;

A system information block (SIB) received in the target spectrum resource, the SIB being a SIB carrying cell access related information;

The channel bandwidth size supported by the first terminal and the bandwidth information of the target spectrum resource, the bandwidth information includes at least one of the following: initial bandwidth, carrier bandwidth (carrierBandwidth), cell bandwidth.

The above-mentioned cell access related information may be related information of the terminal accessing the cell.

In some implementations, the above SIB may include SIB1.

It should be noted that, in the embodiment of the present application, the above SIB is not limited to SIB1. For example, in a subsequent protocol version, the cell access related information carried by SIB1 is carried by other SIBs, and the above SIB is carried by these other SIBs.

In this implementation, it is possible to determine whether the first terminal accesses or is allowed to access a cell that uses the target spectrum resources based on the above-mentioned MIB, SIB, channel bandwidth size, and bandwidth information of the target spectrum resources. This can improve the flexibility and compatibility of terminal access processing to meet the needs of more access scenarios.

Optionally, when a second preset condition is met, determining that the first terminal does not access or is not allowed to access a cell using the target spectrum resources;

The second preset condition includes at least one of the following:

The MIB includes a first preset indication content;

The SIB includes a second preset indication content;

The relationship between the channel bandwidth size supported by the first terminal and the bandwidth information of the target spectrum resource is a first preset relationship;

The relationship between the channel bandwidth size supported by the first terminal and the bandwidth information of the target spectrum resource is not a second preset relationship.

The second preset condition may be defined in the protocol or configured on the network side.

The first preset indication content, the second preset indication content, the first preset relationship, and the second preset relationship may be defined in the protocol or configured on the network side.

It should be noted that the second preset condition includes at least one of the following, which can be understood as, when any one or more of the above conditions are met, it is determined that the first terminal does not access or is not allowed to access the cell using the target spectrum resources.

In this implementation, it can be achieved based on at least one of the first preset indication content, the second preset indication content, the first preset relationship, and the second preset relationship to determine that the first terminal does not access or is not allowed to access the cell using the target spectrum resources.

Among them, the first terminal is prohibited or blocked from accessing the target spectrum resource through the MIB, so that the first terminal does not need to read the information of the SIB (such as SIB1) to determine whether the target spectrum resource is allowed to be accessed, or whether the first terminal accesses the target spectrum resource. Therefore, the first terminal can reduce the time it stays in the cell that does not allow access, so that the first terminal saves power and reduces the delay of accessing the cell that allows it to access.

By prohibiting or preventing the first terminal from accessing the target spectrum resources through SIB1, the compatibility with the first terminal can be improved.

The first terminal is prohibited or blocked from accessing the target spectrum resources by using the first preset relationship and the second preset relationship. This eliminates the need to adjust messages defined in the protocol, thereby reducing the complexity of prohibiting or blocking the first terminal from accessing the target spectrum resources.

As an optional implementation manner, the MIB includes the first preset indication content, which may include at least one of the following:

The cell barring indication field (cellBarred) in the MIB indicates barring;

A value of a subcarrier offset between a synchronization signal block (SSB) and a control resource set (CORESET) indicated by the MIB is greater than a first preset value, and the CORESET is a CORESET that schedules the SIB;

The value of the configuration field of the CORESET of the scheduling SIB in the MIB is a second preset value;

The value of the configuration field of the search space of the scheduling SIB in the MIB is a third preset value.

In some implementations, the CORESET may include: CORESET#0.

It should be noted that the embodiments of the present application do not limit the above CORESET to CORESET#0. For example, it may be other CORESETs defined in the protocol for scheduling the above SIB.

In some implementations, the search space includes search space #0.

It should be noted that the embodiments of the present application do not limit the search space to search space #0. For example, it may be other search spaces defined in the protocol for scheduling the SIB.

In some implementations, k _SSB may be used to represent the subcarrier offset between the SSB indicated by the MIB and the CORESET.

The configuration field of the CORESET of the scheduling SIB in the above-mentioned MIB may be the control resource set zero (controlResourceSetZero) field in the MIB, and the configuration field of the search space of the scheduling SIB in the above-mentioned MIB may be the search space zero (searchSpaceZero) field in the MIB.

In addition, the configuration field of the CORESET of the scheduling SIB in the above-mentioned MIB and the configuration field of the search space of the scheduling SIB in the MIB can be two fields in the physical downlink control channel (PDCCH)-SIB configuration in the MIB, such as two fields in the physical downlink control channel-SIB1 configuration (pdcch-ConfigSIB1).

The first preset value, the second preset value and the third preset value may be values defined in the protocol or values configured on the network side.

In some implementations, the first preset value includes 24; or,

The second preset value includes reserved; or,

The third preset value includes reserved.

It should be noted that, in the embodiment of the present application, the first preset value is not limited to 24, for example, the first preset value may be other values defined in the protocol, such as 36, 48, etc. The second preset value and the third preset value are not limited to being reserved, for example, in some implementations, the second preset value may be a value defined in the protocol for indicating that the configuration field of the CORESET of the scheduling SIB in the MIB is for other purposes other than the CORESET configuration, and the third preset value and the third preset value may be a value defined in the protocol for indicating that the configuration field of the search space of the scheduling SIB in the MIB is for other purposes other than the search space configuration.

In the above implementation, it is possible to prohibit or block the first terminal from accessing the target spectrum resource through the MIB, so that the first terminal does not need to read the information of the SIB (such as SIB1) to determine whether the target spectrum resource is allowed to be accessed, or whether the first terminal accesses the target spectrum resource. This can reduce the time the first terminal stays in a cell that does not allow access, save power for the first terminal, and reduce the delay in accessing a cell that allows it to access.

As an optional implementation manner, the SIB includes a second preset indication content, including at least one of the following:

The value of the field (cellReservedForOperatorUse field) in the SIB used to indicate the reserved cell for the operator is reserved;

The SIB contains a field (cellReservedForOtherUse field) for indicating reserved cells for other purposes;

The SIB contains a field (cellReservedForFutureUse field) for indicating a reserved cell for future use.

In this implementation, the above field of the above SIB can be used to prohibit or prevent the first terminal from accessing the target spectrum resources, which improves the compatibility with the first terminal and enables the terminal to more reliably determine whether the first terminal accesses or is allowed to access the cell that uses the target spectrum resources.

As an optional implementation manner, the initial bandwidth includes at least one of the following:

The bandwidth of the initial uplink bandwidth part (Bandwidth Part, BWP), the carrier bandwidth indicated in the initial uplink BWP, the bandwidth of the initial downlink BWP, the carrier bandwidth indicated in the initial downlink BWP;

The channel bandwidth size supported by the first terminal includes at least one of the following:

an uplink channel bandwidth with a maximum transmission bandwidth configuration supported by the first terminal;

A downlink channel bandwidth with a maximum transmission bandwidth configuration supported by the first terminal.

The carrier bandwidth indicated in the initial uplink BWP may be the carrier bandwidth configured by the network in the uplink common configuration (uplinkConfigCommon) of the initial uplink BWP.

The carrier bandwidth indicated in the initial downlink BWP may be the carrier bandwidth configured by the network in the downlink common configuration (downlinkConfigCommon) of the initial downlink BWP.

In this implementation, it is possible to determine whether the first terminal accesses or is allowed to access a cell that uses the target spectrum resources based on the relationship between multiple bandwidths and channel bandwidth sizes. This can improve the compatibility of terminal access processing to meet the needs of more types of terminals or scenarios.

Optionally, the first preset relationship includes at least one of the following:

The uplink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is greater than the carrier bandwidth indicated in the initial uplink BWP;

The uplink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is smaller than the bandwidth of the initial uplink BWP;

The downlink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is greater than the carrier bandwidth indicated in the initial downlink BWP;

The downlink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is smaller than the bandwidth of the initial downlink BWP.

In this implementation manner, it is possible to determine, under at least one of the above-mentioned preset relationships, that the first terminal does not access or is not allowed to access a cell that uses the target spectrum resources, thereby avoiding terminal access failure, and further enabling the first terminal to reduce the time it stays in a cell that does not allow access, thereby saving power for the first terminal and reducing the delay in accessing a cell that is allowed to access.

For example: if the carrierBandwidth indicated by the network in the uplinkConfigCommon of the initial uplink BWP is smaller than the uplink channel bandwidth supported by the first terminal with the maximum transmission bandwidth configuration, or the carrierBandwidth indicated by the network in the downlinkConfigCommon of the initial downlink BWP is smaller than the downlink channel bandwidth supported by the first terminal with the maximum transmission bandwidth configuration, the first terminal believes that the network of the target spectrum resources does not allow it to access.

Optionally, the second preset relationship includes at least one of the following:

The uplink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is greater than or equal to the bandwidth of the initial uplink BWP;

The downlink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is less than or equal to the carrier bandwidth indicated in the initial downlink BWP;

The downlink channel bandwidth with the maximum transmission bandwidth configuration supported by the first terminal is greater than or equal to the bandwidth of the initial downlink BWP.

In this implementation manner, it is possible to determine that the first terminal does not access or is not allowed to access the cell using the target spectrum resources without at least one of the above-mentioned preset relationships, thereby avoiding terminal access failure, and further allowing the first terminal to reduce the time it stays in the cell that does not allow access, thereby saving power for the first terminal and reducing the delay in accessing the cell that it is allowed to access.

Optionally, when the relationship between the channel bandwidth size supported by the first terminal and the bandwidth information of the target spectrum resource is the second preset relationship, it is determined that the first terminal accesses or is allowed to access a cell that uses the target spectrum resource.

In this implementation manner, it can be achieved that under the above-mentioned second preset relationship, it is determined that the first terminal accesses or is allowed to access a cell that uses the target spectrum resources, thereby reducing the terminal access delay.

For example, the first terminal determines that the first terminal accesses or is allowed to access a cell using the target spectrum resource under one of the following conditions:

The first terminal supports an uplink channel bandwidth with a maximum transmission bandwidth configuration that is less than or equal to carrierBandwidth (indicated by the network in uplinkConfigCommon of the initial uplink BWP) and greater than or equal to the bandwidth of the initial uplink BWP;

The first terminal supports a downlink channel bandwidth with a maximum transmission bandwidth configuration that is less than or equal to carrierBandwidth (indicated by the network in downlinkConfigCommon of the initial downlink BWP) and greater than or equal to the bandwidth of the initial downlink BWP.

In an embodiment of the present application, the first terminal obtains target information, the target information is associated with a target spectrum resource, and the spectrum resource bandwidth of the target spectrum resource satisfies a first preset condition; the first terminal determines whether the first terminal accesses or is allowed to access a cell using the target spectrum resource based on the target information. In this way, the first terminal determines whether the first terminal accesses or is allowed to access a cell using the target spectrum resource for the target spectrum resource, so compared with the terminal directly accessing the target spectrum resource, the embodiment of the present application can improve the access performance of the terminal.

Please refer to FIG. 3 , which is a flow chart of an information processing method provided in an embodiment of the present application. As shown in FIG. 3 , the method includes the following steps:

Step 301: A second terminal receives target information in a target spectrum resource, and a spectrum resource bandwidth of the target spectrum resource satisfies a first preset condition.

The second terminal and the first terminal in the above embodiment are terminals of different types or versions. For example, the first terminal is a traditional/legacy/old version terminal, and the second terminal is a new terminal (new UE) or a new version terminal.

In some implementations, the second terminal may be a terminal used for railway communications, smart grid control, or public safety, and this is not specifically limited.

In some implementations, the second terminal may support all or part of the functions of cross-commercial frequency bands and commercial roaming, or the second terminal may be directly connected to the power grid via a backup power supply.

The above-mentioned target spectrum resources refer to the corresponding description of the embodiment shown in FIG2 , which will not be described in detail here.

The target information may be information sent by the network side received by the second terminal in the target spectrum resource.

Step 302: The second terminal performs a target behavior, where the target behavior includes at least one of the following:

Ignore a preset indication field related to a cell in the target information;

Ignore the relationship between the channel bandwidth supported by the second terminal and the bandwidth information of the target spectrum resource;

Determine, based on the target information, whether the second terminal accesses or is allowed to access a cell that uses the target spectrum resources;

Determine configuration information of a control resource set CORESET indicated by the target information, where the CORESET is a CORESET that schedules a system information block SIB, and the SIB is a SIB that carries information related to cell access;

Determine the association information between the synchronization signal block SSB carrying the target information and the SIB.

The above-mentioned preset indication field related to the cell may be a field specified in the protocol.

The above-mentioned ignoring of the preset indication field related to the cell in the target information may be that the terminal ignores the preset indication field related to the cell in the target information when accessing the target spectrum resources, or before accessing the target spectrum resources, that is, the preset indication field related to the cell in the above-mentioned target information indicates that access is prohibited, and the second terminal also ignores it and accesses the above-mentioned access target spectrum resources.

The relationship between the channel bandwidth supported by the second terminal and the bandwidth information of the target spectrum resource can be found in the corresponding description of the embodiment shown in FIG. 2 , which will not be elaborated here.

The above-mentioned determination of whether the second terminal accesses or is allowed to access the cell using the target spectrum resources based on the target information may be, according to the indication content of the target information, or the fields contained in the target information, to determine whether the second terminal accesses or is allowed to access the cell using the target spectrum resources.

It should be noted that, in some implementations of this embodiment, the second terminal may not perform the above-mentioned determination of whether the second terminal accesses or is allowed to access the cell that uses the target spectrum resources, such as the second terminal accesses the cell that uses the target spectrum resources by default, or the cell that uses the target spectrum resources by default allows the second terminal to access.

It should be noted that, in this embodiment, the configuration information of CORESET may not be determined, or the association information between the SSB that does not carry the target information and the SIB may be determined. For example, the second terminal performs blind detection to obtain corresponding information for cell access.

Among them, the above-mentioned CORESET and SIB refer to the corresponding description of the embodiment shown in Figure 2, and will not be repeated here.

The above-mentioned determination of the configuration information of the CORESET indicated by the target information may be to determine the configuration information of the CORESET indicated by the target information according to the indication content of the target information, or the fields included in the target information, etc.

The above-mentioned determination of the association information between the SSB carrying the target information and the SIB may be to determine whether the SSB carrying the target information is associated with the above-mentioned SIB, and to determine whether the SSB carrying the target information is associated with SIB1.

In this embodiment, by ignoring the preset indication field related to the cell in the target information, it is possible to ignore the preset indication field related to the cell in the target information when performing access to the target spectrum, so as to avoid these fields affecting the second terminal's access to the target spectrum resources, thereby improving the access performance of the second terminal.

In this embodiment, by ignoring the relationship between the channel bandwidth size supported by the second terminal and the bandwidth information of the target spectrum resources, it is possible to ignore the relationship when performing access to the target spectrum, so as to avoid the relationship affecting the second terminal's access to the target spectrum resources, thereby improving the access performance of the second terminal.

In this embodiment, since whether the second terminal accesses or is allowed to access the cell using the target spectrum resources is determined based on the target information, when it is determined that the second terminal does not access or is not allowed to access the cell using the target spectrum resources, network congestion of the target spectrum resources can be reduced, or interference of the target spectrum resources can be reduced, or power consumption of the terminal can be reduced, thereby improving the access performance of the terminal.

In this embodiment, since the configuration information of the control resource set CORESET indicated by the target information is determined, when accessing the target spectrum resource, access can be performed based on the configuration information to reduce access delay and thereby improve access performance of the terminal.

In this embodiment, since the association information between the synchronization signal block SSB carrying the target information and the SIB is determined, when accessing the target spectrum resources, access can be performed based on the association information to reduce the access delay and thereby improve the access performance of the terminal.

The spectrum resource bandwidth is less than or equal to the first preset bandwidth;

The spectrum resource bandwidth is greater than or equal to a second preset bandwidth, and the second preset bandwidth is less than the first preset bandwidth;

The spectrum resource bandwidth is different from the bandwidth combination size. The bandwidth combination size is a bandwidth size obtained by adding any N bandwidth sizes among multiple bandwidth sizes defined in the protocol, where N is an integer greater than 1.

Optionally, the first preset bandwidth includes: a channel bandwidth of 5 MHz, or a transmission bandwidth of 5 MHz; or

The second preset bandwidth includes: a channel bandwidth of 3 MHz, or a transmission bandwidth of 3 MHz; or

As an optional implementation manner, the target information includes at least one of the following:

MIB;

The SIB.

In this implementation, the target behavior can be performed according to the MIB or SIB, which can improve the flexibility and compatibility of terminal access processing to meet the needs of more access scenarios.

The cell barred indication field (cellBarred) in the MIB;

A field in the SIB for indicating reserved cells for other purposes (cellReservedForOtherUse);

A field (cellReservedForFutureUse) in the SIB is used to indicate a reserved cell for future use.

In this implementation, at least one of the above fields may be ignored to prevent the above field from affecting the second terminal's access to the target spectrum resource, thereby improving the terminal's access performance. For example: a) when cellBarred in a cell MIB is set to barred, the field is ignored by the second terminal.

As an optional implementation manner, determining whether the second terminal accesses or is allowed to access a cell using the target spectrum resources based on the target information includes:

In a case where the first indication field included in the SIB indicates that access is allowed, determining that the second terminal accesses or is allowed to access the cell using the target spectrum resources; in a case where the first indication field indicates that access is not allowed, determining that the second terminal does not access or is not allowed to access the cell using the target spectrum resources; or

In a case where the SIB includes a third indication field, it is determined that the second terminal does not access or is not allowed to access a cell that uses the target spectrum resources. In a case where the SIB does not include the third indication field, it is determined that the second terminal accesses or is allowed to access a cell that uses the target spectrum resources. The third indication field is a field used to indicate that access is not allowed.

The first indication field, the second indication field and the third indication field may be fields newly defined in the SIB, such as a new information element (IE).

In some implementations, the first indication field may be referred to as a cell barred indication for less than 5 MH (cellBarredForLessThan5MH) or a cell barred indication for dedicated spectrum (cellBarredForDedicatedSpectrum).

In this implementation, it is possible to directly determine whether to access the target spectrum resource based on the first indication field, the second indication field or the third indication field to reduce complexity. For example, the first indication field in SIB1 is read. If the first indication field indicates that the second terminal is allowed to access, the second terminal considers that the cell allows it to access; otherwise, the second terminal considers that the cell does not allow it to access, that is, the cell status is prohibited.

In this way, there is no need to introduce additional protocol configurations, and the configuration defined in the protocol can be used to take specific values, so that the time-frequency domain resources of the CORESET match the target spectrum resources, thereby improving the transmission performance of the CORESET.

The time-frequency domain resource configurations in the second table that do not match the channel bandwidth of the second terminal may be, and these time-frequency domain resource configurations may be applied to the first terminal in the embodiment shown in FIG. 2 .

For example, the second table above can be shown as Table 2:

Table 2:

In this implementation, the configuration table of CORESET defined in the extended protocol can be used for the target spectrum resources. This reduces the complexity of enabling the terminal to access the target spectrum resources because no additional table needs to be introduced.

Optionally, the index corresponding to the configuration field or M bit of the CORESET of the scheduling SIB in the MIB in the second table is a preset index, and the time-frequency domain resource configuration indicated by the preset index in the second table matches the channel bandwidth of the second terminal.

The preset index may be a default index, an index defined by a protocol, or an index configured on the network side, for example, using the default 0 or 3, as shown in Table 3 below:

In this implementation, the above implementation can accurately determine whether the SSB carrying the MIB is associated with the SIB, which is beneficial to improving the terminal access performance.

As an optional implementation, the method further includes:

When it is determined that the SSB carrying the target information is not associated with the SIB, the frequency domain position of the SSB associated with the SIB is determined.

Among them, the above-mentioned determination that the SIB that the SSB carrying the MIB is not associated with may be to determine the global synchronization channel number (Global Synchronization Channel Number, GSCN) of the SSB associated with the above-mentioned SIB, or may be to determine the GSCN range of the SSB associated with the above-mentioned SIB.

In this implementation, since when it is determined that the SSB carrying the target information is not associated with the SIB, the frequency domain position of the SSB associated with the SIB is determined, the terminal can receive the above SSB based on the frequency domain position, which is beneficial to improving the terminal access performance.

As an optional implementation manner, the determining the configuration information of the CORESET indicated by the target information includes:

The configuration information of the CORESET is determined according to the position of the synchronization grid where the SSB carrying the MIB is located.

The above-mentioned determining the configuration information of the CORESET according to the position of the synchronization grid where the SSB carrying the MIB is located may be determining at least one of the following items of the CORESET:

Number of RBs, RB offset.

In some embodiments, when the position of the synchronization grid where the SSB carrying the MIB is located is the position of the first synchronization grid, the time-frequency domain resource configuration of the CORESET is determined according to the value of the control resource set field in the SIB configuration in the MIB, and the configuration information includes at least one of the following: the number of occupied RBs, and the RB offset.

In some implementations, when the position of the synchronization grid where the SSB carrying the MIB is located is the position of the second synchronization grid, the configuration information of the CORESET is determined to be a default time-frequency domain resource configuration, and the default time-frequency domain resource configuration matches the target spectrum resources.

The above-mentioned default time-frequency domain resource configuration may be a configuration defined in the protocol, or a configuration pre-specified by the network side.

The matching of the above-mentioned default time-frequency domain resource configuration and the target spectrum resource can refer to the matching of the time-frequency domain resources of CORESET and the target spectrum resource described in the above-mentioned implementation mode, which will not be repeated here.

In some implementations, the default time-frequency domain resource configuration includes at least one of the following:

RB offset of 0;

The number of resource blocks is less than 24 RBs.

For example: in the default time-frequency domain resource configuration, Offset(RBs)=0, Number of RBs<24, use Number of RBs=12, or 15, or 18, or 20.

The position of the first synchronization grid may be the position of a synchronization grid defined in the protocol, and the position of the second synchronization grid may be the position of a synchronization grid newly defined in the protocol, or the position of a synchronization grid not defined in the protocol. Specifically, the position of the first synchronization grid and the position of the second synchronization grid are defined by the protocol or configured on the network side.

In this implementation, the configuration information of the CORESET can be determined according to the position of the synchronization grid where the SSB carrying the MIB is located, and the determined configuration information of the CORESET can be matched with the above-mentioned target spectrum resources, thereby facilitating the second terminal to access the target spectrum resources.

For example, if the position of the synchronization grid where the current SSB is located is the position of the first synchronization grid (for example, the position of the synchronization grid of the existing or current version), the terminal uses the value of Number of RBs and/or Offset (RBs) in index;

If the synchronization grid position where the current SSB is located is the second synchronization grid position (for example, not the position of the existing or current version of the synchronization grid), that is, the channel bandwidth of the target frequency domain resource also includes the new synchronization grid position, the second terminal ignores the value of the Number of RBs and/or Offset (RBs) in the indicated index, and considers that the actual Offset (RBs) of CORESET#0 is 0, Number of RBs<24, and uses Number of RBs=12, or 15, or 18, or 20.

Optionally, after determining the time-frequency domain resource configuration of the CORESET according to the value of the control resource set field in the SIB configuration in the MIB, the method further includes:

In a case where the second terminal demodulates the PDCCH on the CORESET and reaches a preset failure condition, it is determined that the configuration information of the CORESET is the default time-frequency domain resource configuration.

The above-mentioned second terminal demodulating the PDCCH on the CORESET to reach a preset failure condition may be that the second terminal fails to demodulate the PDCCH on the CORESET for a preset number of times. For example: if the second terminal fails to demodulate the PDCCH transmitted on CORESET#0 N times, N>=1, and the value of N depends on the terminal implementation, then the second terminal ignores the value of Number of RBs and/or Offset(RBs) in the indicated index, and considers that the actual Offset(RBs) of CORESET#0 is 0, Number of RBs<24, and uses Number of RBs=12, or 15, or 18, or 20.

In this implementation, since the preset failure condition is reached, the configuration information of the CORESET is determined to be the default time-frequency domain resource configuration, so that the terminal can access based on the default time-frequency domain resource configuration, making it easier for the terminal to access the target spectrum resources.

As an optional implementation manner, the bandwidth information includes at least one of the following: initial bandwidth, carrier bandwidth, and cell bandwidth.

The bandwidth information mentioned above can be found in the corresponding description of the embodiment shown in FIG. 2 , and will not be elaborated here.

For general terminals (eg, the first terminal), at least one of the above relationships indicates that the target spectrum resources allow these terminals to access. In this implementation, the second terminal ignores these relationships, so that the second terminal can access the target spectrum resources to improve the access performance of the terminal.

For example, the relationship between the channel bandwidth supported by the second terminal and the cell bandwidth and initial bandwidth configured by the network is ignored, that is, even if the following situation occurs, the second terminal does not consider that the network does not allow access:

The relationship between a bandwidth different from the bandwidth combination size (ie, a bandwidth that cannot be obtained by adding any multiple values of the channel bandwidth size currently defined by the protocol) and the bandwidth information of the target spectrum resource.

In this embodiment, the second terminal ignores the relationship between the channel bandwidth size supported by the second terminal and the bandwidth information of the target spectrum resource to avoid these relationships affecting the second terminal's access to the target spectrum resource and improve the terminal's access performance. For example, these relationships indicate that the terminal is not allowed to access the target spectrum resource, and the second terminal also ignores these relationships and accesses the target spectrum resource. For example, these relationships prohibit the first terminal from accessing the target spectrum resource.

As an optional implementation, the method further includes at least one of the following:

In a case where it is determined that the second terminal accesses or is allowed to access the cell using the target spectrum resources, the second terminal accesses the cell using the target spectrum resources.

In this embodiment, the access performance of the terminal can be improved by the second terminal executing the above target behavior.

Please refer to FIG. 4, which is a flowchart of a configuration sending method provided in an embodiment of the present application. As shown in FIG. 4, the method includes the following steps:

Step 401: The network side device sends a SIB configuration to the terminal in the target spectrum resource, the configuration of the CORESET indicated by the SIB configuration matches the target spectrum resource, the spectrum resource bandwidth of the target spectrum resource meets the first preset condition, the CORESET is used to schedule the CORESET of the SIB, and the SIB is a SIB carrying cell access related information.

The terminal may be the first terminal in the embodiment shown in FIG. 2 , or the second terminal in the embodiment shown in FIG. 3 .

The configuration of the above CORESET may be the configuration of the CORESET for scheduling SIB in the embodiment shown in FIG. 2 , such as the control resource set zero (controlResourceSetZero) field.

The above SIB configuration may be pdcch-ConfigSIB (eg, pdcch-ConfigSIB1).

Among them, the above-mentioned target spectrum resources, the first preset condition, the above-mentioned CORESET, and the above-mentioned SIB can refer to the corresponding descriptions of the embodiments shown in Figures 2 and 3, and will not be repeated here.

In this embodiment, since the configuration of the CORESET matches the target spectrum resources, the terminal can access the target spectrum resources based on the configuration of the CORESET, thereby improving the access performance of the terminal.

Optionally, the first preset condition includes at least one of the following:

The spectrum resource bandwidth is less than or equal to the first preset bandwidth;

The spectrum resource bandwidth is greater than or equal to a second preset bandwidth, and the second preset bandwidth is less than the first preset bandwidth;

The spectrum resource bandwidth is different from the multiple bandwidth sizes defined in the protocol;

The spectrum resource bandwidth is different from the bandwidth combination size. The bandwidth combination size is a bandwidth size obtained by adding any N bandwidth sizes among multiple bandwidth sizes defined in the protocol, where N is an integer greater than 1.

Optionally, the first preset bandwidth includes: a channel bandwidth of 5 MHz, or a transmission bandwidth of 5 MHz; or

The number of symbols occupied by the CORESET indicated by the SIB configuration is greater than or equal to 2.

The number of RBs that can be configured by the CORESET may be the number of RBs shown in Table 2, such as 24, 48, 96, etc., which may be specifically defined by the protocol or configured by the network side. For example, the target number of RBs is 24.

In this implementation, since the number of RBs occupied by CORESET is the target number of RBs, or the number of symbols occupied by CORESET is greater than or equal to 2, the terminal can access the target spectrum resources based on the configuration of the CORESET, thereby improving the access performance of the terminal.

In this embodiment, since the configuration of the CORESET matches the target spectrum resources, the terminal can access the target spectrum resources based on the configuration of the CORESET, thereby improving the access performance of the terminal.

The following is an example of the method provided in the embodiment of the present application through multiple embodiments:

Embodiment 1:

This embodiment mainly uses two cases as examples:

Case 1: The second terminal reads a value of k _SSB greater than 24 in the MIB.

In case 1, the second terminal executes at least one of the following methods:

Method 1: The terminal determines whether the SSB carrying the MIB has an associated SIB1 based on the lower two bits corresponding to the SSB index in the PBCH, that is, whether the network schedules the transmission of CORESET#0 of SIB1. or or bits indicate, where is the number of bits generated by the higher layer, and the 8 bits of the physical layer are

Method 2: The terminal uses the MIB Instructions to determine whether the SSB carrying the MIB has an associated SIB1. The last bit that generates bits for the higher layer.

For example: Or when the spare bit is indicated as 0, it means that the first SSB carrying the MIB has no associated SIB1; if the value range of k _SSB is 24 to 30, the second terminal can determine the nearest (in the corresponding frequency direction) GSCN of the second SSB associated with SIB1, namely CORESET#0, and the second SSB in It is the GSCN of the first SSB, is the GSCN offset indicated by pdcch-ConfigSIB1; if k _SSB = 31, it is determined to be within the GSCN range There is no SS/PBCH block with an associated Type 0 PDCCH common search space set (Type0-PDCCH CSS set). and They are indicated by controlResourceSetZero IE (most significant bit (MSB)) and SearchSpaceZero IE in pdcch-ConfigSIB1 respectively.

Another example: Or when the spare bit indication is 1, it means that the SSB carrying the MIB has an associated SIB1, and the second terminal determines the configuration information of CORESET#0 that schedules the SIB1 according to pdcch-ConfigSIB1.

Method 3: The terminal assumes that the first SSB carrying the MIB has an associated SIB1. The terminal determines the configuration information of CORESET#0 that schedules SIB1 based on pdcch-ConfigSIB1, and monitors the PDCCH transmitted on CORESET#0. If the terminal can successfully demodulate the PDCCH, it means that the first SSB carrying the MIB does have an associated SIB1; otherwise, the terminal determines that the first SSB carrying the MIB does not actually have an associated SIB1. The second terminal executes the above-mentioned content of determining GSCN and determines the frequency domain position of the second SSB carrying SIB1 based on the value of k _SSB .

Case 2: When the second terminal reads the value of controlResourceSetZero in pdcch-ConfigSIB1 in the MIB as at least one of the following:

When the first terminal considers it to be a reserved value, for example, the index in Table 2 above is 15;

The number of symbols occupied by CORESET#0 in the time domain as seen by the first terminal is 1;

The number of RBs occupied by CORESET#0 in the frequency domain as seen by the first terminal 48 or 96;

If the value is at least one of the above items, the second terminal determines that the SSB carrying the MIB is associated with the SIB1; otherwise, the second terminal determines that the SSB carrying the MIB is associated with the SIB1.

Embodiment 2:

In one implementation, a new CORESET#0 configuration table may be defined for the target frequency domain resource size. When the second terminal reads that the k _SSB value in the MIB is greater than 24, the second terminal uses the controlResourceSetZero or 2-bit in pdcch-ConfigSIB1 to or 3bit ( The indication of spare bit) determines the time domain and frequency domain resource configuration of CORESET#0.

The configuration table of the new CORESET#0 includes at least one of the following:

SS/PBCH block and CORESET multiplexing pattern

Number of Symbols occupied,

The number of RBs in the frequency domain.

REG bundle size, the value can be 2, 3, 6

Precoding granularity, the value can be REG bundle, allContiguousRBs

Offset(RBs)

Whether to use REG-to-CCE Interleaving.

The configuration table of the new CORESET#0 may be as shown in Table 1 in the above embodiment, which will not be described in detail here.

In one implementation, the configuration table of CORESET#0 defined in the protocol may be extended to be used for the 3 MHz channel bandwidth, as shown in Table 2 in the above embodiment, which will not be described in detail here.

When the second terminal reads that the value of controlResourceSetZero in pdcch-ConfigSIB1 in the MIB is at least one of the following, the second terminal uses a default value of an index to determine the time-frequency domain resource configuration of CORESET#0:

The number of symbols that CORESET#0 occupies in the time domain is 1, or

The number of RBs that CORESET#0 occupies in the frequency domain is 48 or 96, or

Index 15.

Among them, the default value of the above index can be as shown in Table 3 in the above embodiment, and will not be repeated here.

In some embodiments, the second terminal 2bit or ( The 3-bit indication of spare bit determines the time and frequency domain resource configuration of CORESET#0.

For example: 2 bits indicate the first 4 indexes of Table 13-1, namely index 0, 1, 2, 3

Another example: ( The spare bit) 3 bits indicate the first 6 indexes of table Table 13-1, namely index 0, 1, 2, 3, 4, 5

In some implementations, a new entry may be designed for index=15, and index15 is used as shown in Table 4 below:

Table 4:

Embodiment three:

In this embodiment, when the network is deployed in the first spectrum resource, that is, the number of RBs actually contained in the first frequency domain resource is greater than 15 RBs but less than 24 RBs, when the network uses Table 2 or Table 4 in the above embodiment to indicate the index of controlResourceSetZero, only index = 0, 1, 2, 3, 4, 5 or 15 can be used.

The second terminal determines the value of Number of RBs or Offset (RBs) in index according to the position of the synchronization grid where the first SSB is detected, which may be specifically as follows:

If the position of the synchronization grid where the first SSB is located is the position of the synchronization grid of the existing or current version, the terminal uses the value of Number of RBs and/or Offset (RBs) in index;

Optionally, if the second terminal fails to demodulate the PDCCH transmitted on CORESET#0 N times, N>=1, the value of N depends on the terminal implementation, then the second terminal ignores the value of Number of RBs and/or Offset(RBs) in the indicated index, and considers that the actual Offset(RBs) of CORESET#0 is 0, Number of RBs<24, and uses Number of RBs=12, or 15, or 18, or 20.

If the position of the synchronization grid where the first SSB is located is not the position of the existing or current version of the synchronization grid, that is, the channel bandwidth of the first frequency domain resource also includes the new synchronization grid position, the second terminal ignores the value of the Number of RBs and/or Offset (RBs) in the indicated index, and considers that the actual Offset (RBs) of CORESET#0 is 0, Number of RBs<24, and uses Number of RBs=12, or 15, or 18, or 20.

The embodiments of the present application can be implemented as follows:

Using the information in MIB/SIB1, or according to the relationship between the channel bandwidth supported by the terminal and the cell bandwidth configured by the network, the first terminal (eg, an old version terminal) is prevented from accessing the network deployed on the target spectrum resources.

For the second terminal (ie: the new version terminal):

Introduce a new cell barring (bar) IE in SIB1;

Ignore IEs of other bars in MIB and/or SIB1;

Determine the configuration information of CORESET#0;

When the network is deployed on the target spectrum resources, it indicates the restrictions on the configuration information of CORESET#0.

In this way, in the embodiment of the present application, it can be achieved that the target spectrum resources (for example, dedicated spectrum) can only be accessed by the second terminal, avoiding the second terminal from accessing the network deployed on the dedicated spectrum, avoiding network congestion and interference, and avoiding consuming the power of the second terminal, while allowing the second terminal to access the network and obtain the correct configuration information of CORESET#0.
