Description

Spectrum resource allocation method, main base station and auxiliary base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a spectrum resource allocation method, a primary base station, and a secondary base station.

Background

According to the international white spectrum paper released recently by FCC (Federal Communications Commission), unlicensed (unlicensed) spectrum resources are larger than licensed spectrum resources. Therefore, the spectrum can be spread by effectively utilizing the unlicensed spectrum, and the LTE (Long-term Evolution) device is applied to the unlicensed spectrum, so that not only can the unlicensed spectrum resources be effectively utilized, but also more effective wireless access can be provided, and the increasing demand for mobile broadband services can be met.

Because the existing LTE technology is designed for licensed spectrum, the licensed spectrum has the advantage that operators can share the licensed spectrum independently and the licensed spectrum is relatively pure. Interference or collisions may exist with communicating using the unlikensed spectrum, including in particular with other technologies (e.g., mutual interference with WiFi) as well as with base stations between different operators.

The feasible scheme of the prior art is as follows: in a CA (carrier aggregation) architecture, an LTE base station device configures an unlicensed spectrum as a Scell (Secondary Cell) of an LTE UE (User Equipment) to the UE, so that the LTE base station device can perform data communication with the UE using the unlicensed spectrum, but since a primary Cell and a Secondary Cell in the CA architecture are connected by an ideal Backhaul (Backhaul), the scheme is applicable, but an MSA (multi stream aggregation) architecture in the current LTE system provides a multi-stream transmission service for the UE through a MeNB (master eNB, main base station) and the SeNB (Secondary eNB, Secondary base station), wherein the serving MeNB and the serving micro base station are connected by the non-ideal Backhaul (Backhaul), and the unlicensed spectrum cannot be used by the prior art scheme. It can be seen that a non-ideal backhaul connection cannot use spectrum resources such as unlicensed spectrum resources through the prior art schemes.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

As shown in fig. 1, fig. 1 is a system architecture for implementing a spectrum resource allocation method in the embodiment of the present invention, where the system architecture includes: a main base station 10, a secondary base station 20, and a user equipment 30.

The embodiment of the present invention provides a spectrum resource allocation method, which is applied to an SeNB side in a system as shown in fig. 1, and specifically, the technical solution in the embodiment of the present invention may be applied to an architecture of an ideal backhaul connection such as CA, and may also be applied to an architecture of a non-ideal backhaul connection such as MSA, and therefore, the present invention does not specifically limit the architecture used in the embodiment of the present invention. Referring to fig. 2, fig. 2 is a flowchart of an SeNB side in an embodiment of the present invention, where the method includes:

s101: the SeNB determines a first spectrum configuration.

Specifically, the process of acquiring available spectrum resources is further included before the SeNB determines the first spectrum configuration. In a specific implementation process, the available spectrum resources are spectrum resources that are not occupied, and specifically include available frequency bands and available time periods of each available frequency band.

The MeNB may also determine the available spectrum resources by other means, such as a message acquired from the core network.

If the resource information is acquired by the SeNB, the SeNB scans the covered cell to determine available spectrum resources, and similarly, the available spectrum resources may be spectrum resources that are not used in the cell covered by the SeNB for its own signal, that is, frequency bands that are not scanned; it may also be a frequency band with a scanned signal strength less than a signal strength threshold. Or determine available spectrum resources from information obtained from the core network.

Specifically, the second spectrum resource includes at least one of the following spectrum configuration items:

1. available frequency bands of the available spectrum resources, wherein the available frequency bands can be frequency point information or frequency band information which can be used;

2. the available time of the available spectrum resource may specifically be a time when the available spectrum resource is not occupied.

3. The available systems of the available spectrum resources comprise a TDD (Time Division duplex) system and an FDD (Frequency Division duplex) system, so that the U-LTE spectrum resources can be selected to be used in the TDD system or the U-LTE spectrum resources can be selected to be used in the FDD system according to actual conditions in the specific implementation process;

4. a maximum transmit power of available spectrum resources;

5. a UE identity configured on an available spectrum resource, specifically, the UE identity is a UE identity of a UE for which the available spectrum resource is used as an auxiliary carrier;

6. RB (Radio bearer) identification of the UE configured to available spectrum resources.

For example, suppose that the available spectrum resources acquired by the MeNB include: an F1 band with an available period of T1, and an F2 band with an available period of T2. The MeNB sets the available frequency band in the second spectrum configuration according to the available spectrum resources to be in the F1 frequency band, and in the F2 frequency band, the available time period satisfies that the time period using the F1 frequency band must be in the T1 time period, and the time period using the F2 frequency band must be in the T2 time period, specifically, the available frequency band and the available time period are determined according to the transmission traffic load. For example, the spectrum configuration items in the second spectrum configuration may be set to have an available frequency band of the available spectrum resources as an F2 frequency band, and an available time period of the available spectrum resources as a T3(T3< T2) time period. Further, other types of spectrum configuration items are further determined according to other information. For example, the available systems of the available spectrum resources may be determined according to the service requirements of the UE, and the maximum transmission power of the U-LTE spectrum resources may be calculated and determined according to the scheduling algorithm of the MeNB.

S22: the SeNB determines the first spectrum configuration according to the second spectrum configuration.

Preferably, after S22, the technical solution in the first embodiment further includes two different embodiments, and the first embodiment continues to execute S23 to S24 after S22:

s23: the SeNB determines to use the second spectrum configuration as the first spectrum configuration.

S24, the SeNB sends a first configuration confirmation message to the MeNB, the first configuration confirmation message for confirming that the SeNB determines to use the second spectrum configuration as the first spectrum configuration. Thereby enabling the MeNB to know the spectrum configuration used by the SeNB.

Specifically, the first embodiment accepts all configuration items in the second spectrum configuration of the MeNB for the SeNB. For example, the spectrum configuration items of the second spectrum configuration set by the MeNB according to the available spectrum resources include: the available frequency bands comprise F1, F2 and F1, the available time period is T1, and the available time period of F2 is T2. The SeNB accepts all configuration items in the second spectrum configuration, then the first spectrum configuration is that the SeNB will use frequency bands F1, F2, the time period that will use F1 is TI, and the time period that will use F2 is T2.

It can be seen from the first embodiment that the SeNB directly uses all configuration items in the second spectrum configuration as the first spectrum configuration, and the SeNB sends the first configuration confirmation message to the MeNB to complete the SeNB determining the first spectrum configuration, which is more convenient.

Referring to FIG. 3B, the second embodiment is to continue executing S25-S26 after S22.

S25: the SeNB determines to use a partial spectrum configuration item carried in the second spectrum configuration as the first spectrum configuration;

s26: the SeNB sends a second configuration confirmation message to the MeNB, wherein the second configuration confirmation message is used for indicating the first spectrum configuration.

Specifically, for example, the available frequency bands of the available spectrum resources configured by the second spectrum are F1 and F2, and the available time periods are: the available period of F1 is T1, the available period of F2 is T1, and the available scheme is TDD. The SeNB uses the available frequency bands of the available spectrum resources in the second spectrum configuration item as F1 and F2, and the available format is TDD format as the first spectrum configuration. The SeNB sends a second configuration confirmation message to the MeNB indicating that the first spectrum configuration is: the SeNB will use frequency bands F1, F2, and the SeNB will use the TDD scheme.

Further, in order to make the spectrum configuration more reasonable, while the SeNB determines to use a part of spectrum configuration items carried by the first spectrum configuration, the SeNB may set other spectrum configuration items in the first spectrum configuration based on the second spectrum configuration according to actual needs.

For example, the available frequency band of the available spectrum resource configured by the second spectrum is F1, F2, and the available time period is: the available period of F1 is T1, the available period of F2 is T1, and the available scheme is TDD.

Then the SeNB accepts that the available frequency band of the available spectrum resource is F1, F2, and the available system is a spectrum configuration item of TDD system, and meanwhile, according to the self requirement of the SeNB, for example, the requirement of service, the available time period of F1 is T1, the available time period of F2 is T1, the time period in which the SeNB will use F1 is T3, and the time period in which the SeNB will use F2 is T4. The spectrum configuration items included in the first spectrum configuration determined by the SeNB according to the second spectrum configuration include: the frequency bands to be used by the SeNB include F1 and F2, the standard to be used is a TDD standard, the time period using F1 is T3, and the time period using F2 is T4. The second configuration confirm message sent by the SeNB to the MeNB indicates that the first spectrum configuration is: the frequency bands to be used by the SeNB include F1 and F2, the standard to be used is TDD, the period during which the SeNB will use F1 is T3, and the period during which the SeNB will use F2 is T4.

Through the above S25, the MeNB and the SeNB can jointly determine the spectrum configuration item in the first spectrum configuration, and the MeNB and the SeNB can know the spectrum configuration mutually, so that the determined spectrum configuration can be more reasonable.

Preferably, on the basis of the first embodiment, in order to ensure that the MeNB determines the spectrum configuration item according to the available U-LTE spectrum resources and better meets the actual requirements of the SeNB, the scheme in the embodiment of the present invention further includes the following procedures:

before the SeNB receives the second spectrum configuration sent by the MeNB, the SeNB sends the capability information of the SeNB to the MeNB. The capability information of the SeNB is used to indicate a spectrum configuration supported by the SeNB. Thereby enabling the SeNB to use the second spectrum configuration determined by the MeNB.

Specifically, there are two ways for the SeNB to send the self capability information of the SeNB to the MeNB, one way is that the MeNB sends a query message to the SeNB to actively query the capability information of the SeNB, and the other way is that the SeNB actively reports the capability information of the SeNB.

Specifically, the capability information of the SeNB may have the following two cases.

First, the capability information of the SeNB includes at least one of:

1. frequency bands of available spectrum resources supported by the SeNB;

2. maximum available power information of available spectrum resources supported by the SeNB, wherein the maximum available power information is maximum transmission power which can be used by the SeNB;

3. the system of available spectrum resources supported by the SeNB.

Second, the capability information of the SeNB is a capability level of the SeNB, and specifically, is defined as a plurality of capability levels, and each capability level sets a plurality of capabilities supported by the SeNB at the capability level, such as a frequency band including available spectrum resources supported by the SeNB at the capability level, maximum available power information of the available spectrum resources supported by the SeNB, a standard of the available spectrum resources supported by the SeNB, and so on.

For example, the second case is illustrated, for example, the SeNB capability levels can be divided into a, B, and C capability levels. The A capability level is: supporting F1 frequency band, F2 frequency band; and supporting the maximum available power of w1 in the frequency band of F1, and using the frequency band F1 by FDD; and supporting the maximum available power of w2 in the F2 frequency band, and supporting the use of F2 in TDD. The B capability level is: f3 is supported, the maximum available power in the F3 band is w3, and F3 is supported for FDD. The C capability level is: f4 is supported, the maximum available power in the F4 band is w4, and F4 is supported for FDD. Then, if it is determined that the SeNB supported capability level in the embodiment of the present invention is the C capability level. The SeNB reports its own capability level C.

And the MeNB determines the spectrum configuration items supported by the SeNB as a second spectrum configuration according to the capability information. Specifically, the MeNB may directly obtain, according to the capability information of the SeNB reported by the SeNB, the spectrum resource corresponding to the spectrum configuration supported by the SeNB. For example, the SeNB supports the F1 frequency band, the scanned U-LTE spectrum resources of other frequency bands are not used as the available U-LTE spectrum resources. Or after the MeNB acquires the available spectrum resources, the MeNB may determine the second spectrum configuration according to the spectrum configuration supported by the SeNB and the available spectrum resources.

As can be seen from the description of the first embodiment, when the MeNB acquires available spectrum resources, the SeNB can determine the first spectrum configuration of the SeNB according to the second spectrum configuration determined by the MeNB, so that spectrum resources such as unlicensed spectrum resources can be used in a non-ideal blackhaul connection.

The second embodiment:

referring to fig. 4, the second embodiment includes the following processes:

s31, the SeNB determines a third spectrum configuration according to the available spectrum resources. Specifically, the third spectrum configuration item determined by the SeNB includes at least one of the following spectrum configuration items:

1. available frequency bands of available spectrum resources;

2. an available time of an available spectrum resource;

3. available systems of available spectrum resources;

4. a maximum transmit power of available spectrum resources;

in a specific implementation process, the third spectrum configuration is the same as or similar to the configuration items in the second spectrum configuration, and for the sake of brevity of the description, please refer to the first spectrum configuration without explaining the spectrum configuration items in the third spectrum configuration.

S32: the SeNB sends the third spectral configuration to the MeNB.

S33: the SeNB receives a third configuration confirmation message sent by the MeNB, and the third configuration confirmation message is a message generated by the MeNB according to the third spectrum configuration and used for indicating the first spectrum configuration.

In the implementation process, the first case: the third configuration confirmation message is used for confirming that the MeNB determines to use the third spectrum configuration as the first spectrum configuration, and at this time, the third confirmation configuration message may be an ack (acknowledgement) message, which indicates that the MeNB accepts all spectrum configuration items determined by the SeNB according to the available spectrum resources. In case one, the spectral configuration items in the first spectral configuration are all the configuration items in the third spectral configuration. Case two: the third configuration confirm message is for indicating the first spectrum configuration. Specifically, the third configuration confirmation message is an indication to select one or more spectral configuration items from the third spectral configuration as the first spectral configuration.

Specifically, the first spectrum configuration in this embodiment includes at least one of the following spectrum configuration items:

1. a frequency band of available spectrum resources to be used by the SeNB;

2. a period of available spectrum resources to be used by the SeNB;

3. a system of available spectrum resources to be used by the SeNB;

4. maximum transmit power used by the SeNB for available spectrum resources;

5. a UE identity configured onto the available spectrum resources;

6. a radio bearer identification of the UE configured onto the available spectrum resources.

In the following, how the second configuration confirmation message indicates the first spectrum in case two is specifically illustrated, but not limiting the invention.

For example, the available frequency bands of the available spectrum resources configured by the third spectrum are F1 and F2, and the available time periods are: the available period of F1 is T1, the available period of F2 is T1, and the available scheme is TDD. The MeNB confirms the use of the spectrum configuration item: the available frequency bands of the available spectrum resources are F1 and F2, and the available mode is TDD mode. The third configuration confirm message sent by the MeNB to the SeNB indicates that the first spectrum configuration is: the SeNB will use frequency bands F1, F2, and the SeNB will use the TDD scheme.

Further, in order to make the spectrum configuration more reasonable, while the SeNB determines to use a part of the spectrum configuration items carried by the third spectrum configuration, the SeNB may also set other spectrum configuration items in the first spectrum configuration based on the third spectrum configuration according to actual needs.

For example, the third spectrum is configured as: the available frequency bands of the available spectrum resources are F1 and F2, and the available time periods are as follows: the available period of F1 is T1, the available period of F2 is T1, and the available scheme is TDD. Then, the MeNB accepts that the available frequency bands of the available spectrum resources are F1 and F2, and the available system is a spectrum configuration item of the TDD system, meanwhile, the MeNB sets the time period for the SeNB to use F1 as T3 and the time period for the SeNB to use F2 as T4 according to other information (for example, the requirements of service requirements and the like) and according to the "available time period of F1 as T1 and the available time period of F2 as T1". The spectrum configuration items included in the first spectrum configuration determined by the MeNB according to the second spectrum configuration include: the frequency bands to be used by the SeNB include F1 and F2, the standard to be used is a TDD standard, the time period using F1 is T3, and the time period using F2 is T4. The second configuration confirm message sent by the SeNB to the MeNB indicates that the first spectrum configuration is: the frequency bands to be used by the SeNB include F1 and F2, the standard to be used is a TDD standard, the time period using F1 is T3, and the time period using F2 is T4.

S34: the SeNB determines the first spectrum configuration according to the third configuration confirmation message. If the third configuration confirm message is the case one, indicating that the MeNB accepts all the spectrum configuration items in the third spectrum configuration determined by the SeNB according to the available spectrum resources, the SeNB uses all the spectrum configuration items in the third spectrum configuration as the first spectrum configuration. And if the third configuration confirms that the second configuration is the case two, the SeNB takes the spectrum configuration item indicated by the third configuration confirmation message as the first spectrum configuration.

In a specific implementation process, a specific configuration item of each spectrum configuration item in the first spectrum configuration in this embodiment refers to a specific description of the first spectrum configuration in the first implementation, and similarly, a configuration item description of the third spectrum configuration refers to a specific description of the second spectrum configuration in the first implementation, and is not repeated here for brevity of the description.

Further, in order to make the available spectrum resources acquired by the SeNB more reasonable, the technical solution in the embodiment of the present invention further includes the following procedures:

the SeNB receives an indication message sent by the MeNB, wherein the indication message is used for indicating the first spectrum resource. The first spectrum resource is a spectrum resource required by the SeNB to the MeNB, and specifically, a spectrum resource allocated by the MeNB to the SeNB in the embodiment of the present invention according to a competition result of multiple senbs, the SeNB in the embodiment of the present invention determines a third spectrum configuration according to the first spectrum resource, and specifically, the first spectrum resource includes frequency band information or frequency point information allocated to the SeNB, an available period, and other information.

As can be seen from the description of the second embodiment, when the SeNB acquires the available spectrum resources, the SeNB can determine the first spectrum configuration according to the available spectrum resources (case one), and can optimize the first spectrum configuration according to the third spectrum configuration message of the MeNB (case two). Therefore, the use of spectrum resources such as unlicensed spectrum resources under non-ideal blackhaul connection can be realized.

In a specific implementation process, in the first and second embodiments, there may be multiple manners for sending and indicating the first spectrum configuration, for example, a configuration item may be directly sent, an identifier or an indication of the first spectrum configuration may be sent, or an implicit notification may be sent, and similarly, there may also be multiple manners for sending other spectrum configurations.

Third embodiment

In a specific implementation process, if the U-LTE spectrum resources are occupied in an LBT (Listen Before Talk) manner, the time that the SeNB occupies the U-LTE available spectrum resources is short, and the SeNB cannot immediately notify the MeNB of the spectrum configuration of the SeNB through a "resource report", then S101 specifically is:

the SeNB sends average spectrum resource information to the MeNB, where the average spectrum resource information is used to indicate a spectrum occupied by the SeNB in a unit time, and specifically, the spectrum occupied by the SeNB in the unit time may be a time length of the spectrum occupied in the unit time, a ratio of the spectrum not occupied in the unit time, and the like. The spectrum occupied by the SeNB per unit time is used for the MeNB to configure the radio bearer of the SeNB.

The first spectrum configuration determined by the SeNB may be determined by the first to third embodiments, and the SeNB is made aware of the first spectrum configuration determined by the SeNB.

S102: the method comprises the step that the SeNB sends a request message to the MeNB, wherein the request message is used for indicating the MeNB to configure an auxiliary carrier of the UE according to a first spectrum configuration, and the auxiliary carrier is used for carrying out data communication between the SeNB and the UE.

Specifically, S102 specifically is: and the SeNB determines the secondary carrier according to the first spectrum configuration. For example, if the available spectrum resources are obtained as shown in the following table (for example only), the SeNB is configured to use the first spectrum determined according to the following table: in a T5(T5< T3) period, an F3 frequency band is used, the system is a TDD system, and the maximum transmission power is W5(W5< W3). Determining that the secondary carrier is an F3 frequency band for configuring the TDD system for the UE at the time period T5:

and the SeNB sends a change request message to the MeNB after determining the secondary carrier, wherein the change request message is used for instructing the MeNB to send a Radio Resource Control (RRC) connection reconfiguration message to the UE. Wherein, the change request information carries the auxiliary carrier information of the auxiliary carrier.

And after receiving the change request information, the MeNB sends an RRC connection reconfiguration message to the UE, wherein the RRC connection reconfiguration message is used for the UE to configure the auxiliary carrier or add the U-LTE auxiliary carrier. Specifically, the change to the secondary carrier indicated in the change request information or the addition of the secondary carrier indicated in the change request information is determined according to the actual RRC connection reconfiguration message.

Preferably, in order for the MeNB to control the change or the addition of the U-LTE secondary carrier, before the SeNB determines the secondary carrier according to the first spectrum configuration, the technical solution in the embodiment of the present invention further includes the following procedure:

and the MeNB sends the auxiliary carrier change indication information to the SeNB. Specifically, the secondary carrier change indication information includes at least one of a UE identifier configured to the secondary carrier, a service configured to the secondary carrier, and a radio bearer identifier configured to the secondary carrier; and the SeNB determines the first spectrum configuration according to the secondary carrier change indication information. Specifically, the MeNB generates secondary carrier change indication information according to the acquired available spectrum resources and the secondary carrier information that the UE has currently configured.

And when the SeNB receives the auxiliary carrier change indication information sent by the MeNB, responding to the auxiliary carrier change indication information and sending auxiliary carrier change request information to the MeNB.

By the spectrum resource allocation method on the SeNB side described in the first embodiment, the SeNB can determine the first spectrum allocation, and even if the SeNB and the MeNB are connected in a non-ideal backhaul manner, can determine a reasonable spectrum allocation corresponding to available spectrum resources, so as to reasonably allocate spectrum resources such as unlicensed spectrum resources to the UE, and use the spectrum resources as secondary carriers of the UE, so as to reasonably use the spectrum resources such as unlicensed spectrum resources.
