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 an auxiliary base station.

Background

According to the latest published international spectrum white paper by FCC (Federal Communications Commission ), unlicensed spectrum resources are larger than licensed spectrum resources. Therefore, the unlicensed spectrum can be effectively utilized to spread the spectrum, and the LTE (Long-term Evolution) device can be applied to the unlicensed spectrum, so that not only can the unlicensed spectrum resource be effectively utilized, but also more effective wireless access can be provided, and the requirement of increasingly mobile broadband service can be met.

Because the existing LTE technology is designed for licensed spectrum, the licensed spectrum has the advantages of being unique to operators and relatively pure. Interference or collision may exist for communications using unlicensed spectrum, including inter-interference with other technologies (e.g., with WiFi) and base stations between different operators.

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

Detailed Description

In order to solve the technical problem that non-ideal backhaul connection cannot use unlicensed spectrum resources, the present embodiment provides a spectrum resource allocation method, a primary base station and an auxiliary base station.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

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

The embodiment of the invention provides a spectrum resource allocation method, which is applied to an SeNB side in a system shown in fig. 1, and in particular, the technical scheme in the embodiment of the invention can be applied to an ideal backhaul connection structure such as CA and the like, and can also be applied to a non-ideal backhaul connection structure such as MSA and the like, so that the invention is not particularly limited to the structure used in the embodiment of the invention. Referring to fig. 2, fig. 2 is a flowchart of an SeNB side in an embodiment of the present invention, where the flow of the method includes:

s101: the SeNB determines a first spectral configuration.

Specifically, before the SeNB determines the first spectrum configuration, a process of acquiring available spectrum resources is further included. In the implementation process, the available spectrum resource is unoccupied spectrum resource, and specifically includes available frequency bands and an available period of each available frequency band. Specifically, the available spectrum resources are available U-LTE spectrum resources, and the U-LTE spectrum resources are unlicensed spectrum resources which are not occupied and used in the LTE technology. Of course, in the specific implementation process, the available spectrum resources not limited to the process in the embodiment of the present invention must be available U-LTE spectrum resources, and other spectrum resources may also be used in the process in the embodiment of the present invention.

In the implementation process, the available spectrum resources may be obtained by the MeNB or may be obtained by the SeNB, which are described below. If the available spectrum resources are acquired by the MeNB, the MeNB scans the cells covered by its own signals to determine the available spectrum resources. Specifically, the determined available spectrum resources may be spectrum resources that are not used in the cell covered by the MeNB, i.e. frequency bands that are not scanned; or may be a frequency band in which the scanned signal strength is less than a signal strength threshold. The MeNB may also determine the available spectrum resources here 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 to the signal, that is, frequency bands that are not scanned; or may be a frequency band in which the scanned signal strength is less than a signal strength threshold. Or information obtained from the core network determines available spectrum resources.

Specifically, according to the aforementioned difference between the network side devices for acquiring the available spectrum resources, S101 in the embodiment of the present invention includes at least three embodiments, and the following description will be given respectively.

The available modes of the available spectrum resources comprise a TDD (Time Division Duplexing, time division duplex) mode and an FDD (Frequency Division Duplexing, frequency division duplex) mode, so that the U-LTE spectrum resources can be used in the TDD mode or the U-LTE spectrum resources can be used in the FDD mode according to actual conditions in the specific implementation process;

4. maximum transmit power of available spectrum resources;

5. the UE identification is configured on the available spectrum resources, and specifically, the UE identification is the UE identification of the UE, which is used as the auxiliary carrier, of the available spectrum resources;

6. RB (Radio bearer) identity configured to the UE on the available spectrum resources.

For example, if 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, according to the available spectrum resources, that the available frequency band in the second spectrum configuration meets the F1 frequency band, and that the available time period meets the F1 frequency band, must be within the T1 time period, and that the F2 frequency band must be within the T2 time period, specifically, determines the available frequency band and the available time period according to the transmission traffic load. For example, the spectrum configuration item in the second spectrum configuration may be set to be that the available frequency band of the available spectrum resource is the F2 frequency band, and the available period of the available spectrum resource is the period of T3 (T3 < T2). Further, other types of spectrum configuration items are further determined according to other information. For example, the available system of the available spectrum resources may be determined according to the service requirement of the UE, and the maximum transmitting power of the U-LTE spectrum resources may be determined by calculation according to the scheduling algorithm of the MeNB.

S22: the SeNB determines the first spectrum configuration from 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.

And S24, the SeNB sends a first configuration confirmation message to the MeNB, wherein the first configuration confirmation message is used for confirming that the SeNB determines to use the second spectrum configuration as the first spectrum configuration. Thereby, the MeNB can learn the spectrum configuration used by the SeNB.

Specifically, the first embodiment is that the SeNB accepts all configuration items in the second spectrum configuration of the MeNB. 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 band comprises F1, F2, wherein the available time period of F1 is T1, and the available time period of F2 is T2. The SeNB accepts all configuration items in the second spectrum configuration, and the first spectrum configuration is such that the SeNB will use the frequency bands F1, F2, the period where F1 will be used is TI, and the period where F2 will be used 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 can complete the determination of the first spectrum configuration by sending the first configuration confirmation message to the MeNB, so that the method is more convenient.

Referring to fig. 3B, the second embodiment is to continue S25 to S26 after S22.

S25: the SeNB determines to use part of spectrum configuration items carried in the second spectrum configuration as the first spectrum configuration;

S26: and 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 band of the second spectrum configured as the available spectrum resource is F1 and F2, and the available period is: the available period of F1 is T1, the available period of F2 is T1, and the available system is TDD system. 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 standard is a TDD standard as the first spectrum configuration. The SeNB sends a second configuration confirm message to the MeNB indicating that the first spectrum configuration is: the frequency bands of the SeNB are F1 and F2, and the use mode of the SeNB is TDD mode.

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 second spectrum configured as the available spectrum resource is F1, F2, and the available period is: the available period of F1 is T1, the available period of F2 is T1, and the available system is TDD system.

The SeNB receives the spectrum configuration items of the available spectrum resources with the available frequency bands of F1 and F2 and the available standard of TDD, and simultaneously, according to the needs of the SeNB itself, for example, the needs of the service needs and the like, the period of time when the SeNB will use F1 is set to be T3 and the period of time when the SeNB uses F2 is set to be T4 from the available period of time of F1 to be T1 and the available period of time of F2 to be T1. The spectrum configuration items included in the first spectrum configuration determined by the SeNB according to the second spectrum configuration include: the frequency band to be used by the SeNB comprises F1 and F2, the system to be used is a TDD system, the period of time to use F1 is T3, and the period of time to use F2 is T4. The second configuration confirm message sent by the SeNB to the MeNB is an indication that the first spectrum configuration is: the frequency band to be used by the SeNB includes F1 and F2, the system to be used is a TDD system, the period of time during which the SeNB uses F1 is T3, and the period of time during which the SeNB uses F2 is T4.

Through the S25, the MeNB and the SeNB can determine the spectrum configuration item in the first spectrum configuration together, 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 that the spectrum configuration item better meets the actual requirement of the SeNB according to the available U-LTE spectrum resources, 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 the 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 capability information of the SeNB itself 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 be in two cases as follows.

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

1. the frequency band of the available spectrum resource supported by the SeNB;

2. the method comprises the steps that the available spectrum resources supported by an SeNB are provided with maximum available power information, wherein the maximum available power information is the maximum transmitting power which can be used by the SeNB;

3. The standard of the available spectrum resources supported by the SeNB.

The second type of capability information of the SeNB is a capability level of the SeNB, specifically, a plurality of capability levels are defined, and a plurality of capabilities supported by the SeNB under the capability level are set in each capability level, for example, a frequency band including available spectrum resources supported by the SeNB under 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 the like.

The second case is illustrated by way of example, for example, the capability levels of the SeNB may be divided into a, B, C capability levels. The A capability level is: supporting an F1 frequency band and an F2 frequency band; and supporting the maximum available power in the F1 frequency band as w1, and using the frequency band F1 by FDD; and supporting the maximum available power in the F2 frequency band as w2 and supporting the frequency band F2 used by TDD. The B capability level is: the frequency band F3 is supported, and the maximum available power in the frequency band F3 is supported as w3, and the frequency band F3 is supported to be used in FDD. The C capability level is: the frequency band F4 is supported, and the maximum available power in the frequency band F4 is supported as w4, and the frequency band F4 is supported to be used in FDD. Then if it is determined that the capability level supported by the SeNB in the embodiment of the present invention is the C capability level. The SeNB reports the SeNB's own capability level C.

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

As can be seen from the description of the first embodiment, in the case where the MeNB obtains the 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 under the non-ideal blackbul connection.

Embodiment two:

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

and 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 spectrum configuration item as follows:

1. an available frequency band of available spectrum resources;

2. the available time of available spectrum resources;

3. The available system of the available spectrum resources;

4. maximum transmit power of available spectrum resources;

in the implementation process, the third spectrum configuration is the same as or similar to the configuration items in the second spectrum configuration, and for brevity of description, the configuration items in the third spectrum configuration are not explained here, please refer to the first spectrum configuration.

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

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

In the specific implementation process, case one: 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 a 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 spectrum configuration items in the first spectrum configuration are all configuration items in the third spectrum configuration. And a second case: the third configuration confirmation message is used for indicating the first spectrum configuration. In particular, the third configuration confirmation message is indicative of selecting one or more spectrum configuration items from the third spectrum configuration as the first spectrum configuration.

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

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

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

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

4. the SeNB uses the maximum transmitting power of the available spectrum resources;

5. configuring UE identification on the available spectrum resources;

6. and configuring a radio bearer identification of the UE on the available spectrum resources.

The following specifically illustrates how the second configuration confirmation message in case two indicates the first spectrum, but is not intended to limit the present invention.

For example, the third spectrum is configured to be an available frequency band of the available spectrum resource, F1, F2, and the available period is: the available period of F1 is T1, the available period of F2 is T1, and the available system is TDD system. The MeNB acknowledges the use of the spectrum configuration item: the available frequency bands of the available spectrum resources are F1 and F2, and the available standard is a TDD standard as a first spectrum configuration. The third configuration confirm message sent by the MeNB to the SeNB indicates that the first spectrum configuration is: the frequency bands of the SeNB are F1 and F2, and the use mode of the SeNB is TDD mode.

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 third spectrum configuration, the SeNB may 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 to: the available frequency bands of the available spectrum resources are F1 and F2, and the available time period is as follows: the available period of F1 is T1, the available period of F2 is T1, and the available system is TDD system. The MeNB accepts the available frequency bands of the available spectrum resources as F1 and F2, the available standard is a spectrum configuration item of the TDD standard, and meanwhile, the MeNB sets a period of time during which the SeNB will use F1 as T3 and a period of time during which F2 is used as T4 according to other information (such as requirements of service requirements and the like) and according to the "available period of time of F1 as T1 and the available period of time 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 band to be used by the SeNB comprises F1 and F2, the system to be used is a TDD system, the period of time to use F1 is T3, and the period of time to use F2 is T4. The second configuration confirm message sent by the SeNB to the MeNB is an indication that the first spectrum configuration is: the frequency band to be used by the SeNB comprises F1 and F2, the system to be used is a TDD system, the period of time to use F1 is T3, and the period of time to use F2 is T4.

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

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

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

the SeNB receives indication information sent by the MeNB, wherein the indication information is used for indicating the first frequency spectrum resource. The first spectrum resource is a spectrum resource required by the SeNB to the MeNB, specifically, the spectrum resource allocated to the SeNB in the embodiment of the present invention by the MeNB according to the result of contention among the plurality of senbs, and then the SeNB in the embodiment of the present invention determines a third spectrum configuration according to the first spectrum resource, where the first spectrum resource specifically includes information such as frequency band information or frequency point information allocated to the SeNB, and an available time period.

As can be seen from the description of the second embodiment, in the case where the SeNB acquires the available spectrum resources, the SeNB can determine the first spectrum configuration from the available spectrum resources (case one) itself, and can optimize the first spectrum configuration from the third spectrum configuration message of the MeNB (case two). Thus, spectrum resources such as unlicensed spectrum resources can be used under a non-ideal blackbul connection.

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

Embodiment III

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

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 unoccupied in the unit time, and so on. The spectrum occupied by the SeNB in unit time is used for the MeNB to configure the radio bearer of the SeNB.

The foregoing embodiments one to three may implement that the SeNB determines the first spectrum configuration, and make the SeNB learn the first spectrum configuration determined by the SeNB determining the first spectrum configuration.

S102: the method comprises the steps 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 User Equipment (UE) according to a first frequency spectrum configuration, and the auxiliary carrier is used for carrying out data communication between the SeNB and the UE.

Specifically, S102 is specifically: and the SeNB determines the auxiliary carrier according to the first spectrum configuration. For example, if the available spectrum resources are obtained as the following table (for illustration only), the SeNB is configured to: and F3 frequency band is used in the period of T5 (T5 < T3), the using mode is TDD mode, and the maximum transmitting power is W5 (W5 < W3). Then determining the secondary carrier as an F3 frequency band for configuring a TDD system for the UE in the T5 period:

after the secondary carrier is determined, the SeNB sends a change request message to the MeNB, where the change request message is used to instruct the MeNB to send an RRC (Radio Resource Control ) connection reconfiguration message to the UE. Wherein, the modification request information carries the auxiliary carrier information of the auxiliary carrier.

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, whether the secondary carrier indicated in the change request information is changed to the secondary carrier indicated in the change request information or the secondary carrier indicated in the change request information is added is determined according to an actual RRC connection reconfiguration message.

Preferably, in order for the MeNB to control the modification or 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 procedures:

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

When receiving the auxiliary carrier change indication information sent by the MeNB, the SeNB responds to the auxiliary carrier change indication information to send auxiliary carrier change request information to the MeNB.

By the spectrum resource allocation method at 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 in non-ideal backhaul connection, the spectrum allocation corresponding to the available spectrum resources can be determined reasonably, so that the spectrum resources such as unlicensed spectrum resources can be allocated to the UE reasonably, and used as auxiliary carriers of the UE, so that the spectrum resources such as unlicensed spectrum resources can be used reasonably.
