The deployment of small cells (Small Cell) and the addition of new frequency points are ways to increase wireless network data traffic. With its rich bandwidth resources (3400-3600MHz, LTE Band42/43), the 3.5GHz band has become a hot spot worldwide.

Long Term Evolution (LTE) system introduces key transmission technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input & Multi-Output), which significantly increases spectrum efficiency and data. The transmission rate, and support for a variety of bandwidth allocation, also supports the global mainstream 2G/3G frequency band and some new frequency bands, so the spectrum allocation is more flexible, and the system capacity and coverage are also significantly improved.

In order to meet the requirements of single-user peak rate and system capacity increase, one of the most direct methods is to increase the system transmission bandwidth. Therefore, the Long Term Evolution Advanced (LTE-Advanced) system introduces a technology for increasing transmission bandwidth, that is, CA (Carrier Aggregation).

detailed description

The embodiment of the present invention provides a method for configuring carrier aggregation, a first device, and a second device, where the first device determines the first multi-carrier frequency band according to the information of the carrier frequency band and the available frequency band information of the usage right in advance. Therefore, the carrier configuration of the base station is adjusted to the first carrier frequency band, and the available frequency band is effectively utilized, that is, the utilization of the spectrum resource is improved.

The Spectrum Access System (SAS) is a centralized management center for 3.5 GHz spectrum. SAS directly or indirectly controls the Citizens Broadband Radio Service Device (CBSD) using the 3.5 GHz spectrum. As shown in FIG. 1 , a schematic diagram of an application scenario of a spectrum access system may include a SAS, a CBSD, a database, a primary user, an Environment Sensing Capability (ESC), a domain proxy (Domain Proxy), and a unit management system ( Other devices such as Element Management System, EMS). It should be noted that the number of CBSDs is not limited. Here is a brief description of the concepts that have emerged above:

SAS is mainly used to collect channel occupancy information of geographical locations; provide a list of available channels for geographic locations; CBSD authentication, registration, etc.;

CBSD mainly refers to devices that use the 3.5 GHz band in spectrum sharing mode;

Database, generally referred to as the Federal Communications Commission (FCC) The database is mainly used for storing information of a Priority Access Layer (PAL) user/device and a General Authorized Access (GAA) user/device;

The main user mainly includes the existing main user information; the exclusive area information;

The ESC is mainly used to listen to the primary user signal; it is determined that the primary user reaches the affected area;

The domain agent is an intermediate management entity that selects the channel used for CBSD or transmits information to the EMS for calculation by the EMS;

The EMS can also be an NMS (Network Management System) network management system, which is an operator network management system. It mainly uses channel and power information for CBSD configuration.

The usage of the Layer 3 channel spectrum resources defined by SAS is as follows:

The user of the Incumbent Access (IA) has the highest priority channel spectrum resource usage right at the first layer, and the other priority access layer users and the general authorized access users cannot interfere with the primary user;

Priority Access (PA) users or Priority Access Layer (PAL) users. At the second level, the channel spectrum resource usage rights of one or more census tracts are obtained through auction, and channel spectrum resources are used. The priority is lower than that of the primary user but higher than that of the GAA user. The channel spectrum resources being used need to exit the spectrum occupation when the primary user arrives, and will not be interfered by the GAA user;

General Authorized Access (GAA) users, at the lowest level, have no interference protection. When an IA user or a PAL user needs to use channel spectrum resources, the GAA needs to give up the channel spectrum resources being used.

As shown in FIG. 2, the application scenario of the technical solution of the present invention includes a user equipment, a base station, and a spectrum access system. The first device mentioned in the embodiment of the present invention may be a network management system (NMS) or a unit management system (EMS). It may be a device such as a base station. In the following embodiments, the first device is described by taking a base station as an example, and the second device may be described by taking a spectrum access system as an example.

In order to meet the requirements of single-user peak rate and system capacity increase, one of the most direct methods is to increase the system transmission bandwidth. Therefore, the LTE-Advanced system introduces a technology for increasing the transmission bandwidth, that is, CA (Carrier Aggregation). Among them, CA is to aggregate 2 or more Component Carriers (CCs) to support a larger transmission bandwidth (up to 100MHz). The maximum bandwidth of each CC is 20MHz. LTE supports in-band continuous CA, in-band non-continuous CA, and out-of-band non-continuous CA, as shown in Figure 3.

In the existing carrier aggregation scheme, the spectrum resources of the carrier aggregation used by the user equipment (User Equipment, UE) are provided by the user equipment according to the static configuration of the spectrum owned by the operator, that is, the user equipment is used in advance according to the operator. The carrier resources of the carrier frequency band of the right carrier band are communicated. The operator cannot adjust the carrier configuration of the carrier according to the dynamic changes in the carrier frequency band at 3.5 GHz, and cannot effectively utilize the spectrum resources of the carrier frequency band at 3.5 GHz. Further, the operator cannot select the multi-carrier frequency band suitable for the user equipment for the user equipment to communicate according to the frequency band information, service parameters, and willingness of the carrier aggregation supported by the user equipment.

In the technical solution of the present invention, the operator can adjust the carrier configuration of the carrier according to the dynamic change of the carrier frequency band at 3.5 GHz, and effectively utilize the spectrum resource, and further, can also be aggregated according to the carrier supported by the user equipment.

After the first device sends the spectrum query request to the second device, the second device receives the spectrum query request sent by the first device, that is, the SAS receives the spectrum query request sent by the eNB. The spectrum query request may include information such as geographic location information, device type, and registration type (PAL, GAA, or Both).

402. The second device determines information about available frequency bands according to the spectrum query request.

In the embodiment of the present invention, the second device determines information about available frequency bands according to the spectrum query request. Specifically, the second device may determine information about the available frequency bands according to the spectrum query request, the currently available spectrum, and the interference situation. That is, the SAS can determine the information of the available frequency bands according to the geographical location information, the device type, the registration type (PAL, GAA, or Both) carried in the spectrum query request, the available spectrum, and the interference situation. The information of the available frequency bands includes at least one of the priority access carrier frequency band PA and the general authorized access carrier frequency band GAA. Here PA and PAL actually mean the same meaning.

Exemplarily, the information of the available frequency band may be information of the PAL frequency band, information of the GAA frequency band, information of the PAL frequency band, and information of the GAA frequency band.

403. The second device sends a spectrum query response to the first device.

In the embodiment of the present invention, step 403 may include two steps c and d, as follows:

c. The second device sends a spectrum query response to the first device, where the spectrum query response includes information about available frequency bands;

In the embodiment of the present invention, after determining the information of the available frequency band, the second device sends a spectrum query to the first device. In response, the spectrum query response includes information of the available channels.

Exemplarily, the information of the available frequency band may be information of the PAL frequency band, information of the GAA frequency band, information of the PAL frequency band, and information of the GAA frequency band.

It can be information of the PAL band, or the information of the GAA band, or the information of the PAL band and the information of the GAA band.

It should be noted that steps 401, 402 and 403 can be summarized as a whole to obtain information of available frequency bands. If it is summarized as obtaining information on the available frequency bands, then steps 401, 402 and 403 are optional steps.

404. The first device determines the first multi-carrier frequency band according to the information of the carrier frequency band and the available frequency band information, and the first multi-carrier frequency band is used by the first device to perform carrier aggregation on the user equipment.

In the embodiment of the present invention, after acquiring the information of the available frequency band, the first device determines the first multi-carrier frequency band according to the information of the access carrier frequency band and the available carrier frequency band obtained in advance, and the first multi-carrier frequency band is used. Carrier aggregation is performed on the user equipment by the first device. The information of the available frequency band includes at least one of a priority access carrier frequency band PA and a general authorized access carrier frequency band GAA.

In an actual application, determining the first multi-carrier frequency band may be: the first device determines the first multi-carrier frequency band according to the information of the available frequency bands, and then the first multi-carrier frequency band includes the preferential access carrier frequency band PA and the general authorized access carrier. Band GAA.

Specifically, the first multi-carrier frequency band includes the following possibilities:

a: the carrier frequency band and the priority access carrier frequency band of the usage right are obtained in advance, as shown in FIG. 5a; or

b: the carrier frequency band in which the usage right is obtained in advance and the general authorized access carrier frequency band, as shown in FIG. 5b;

d: Priority access to the carrier frequency band PA and the general authorized access carrier frequency band GAA, as shown in Figure 5d.

It should be noted that, in FIG. 5a, 5b, and 5c, it is assumed that the information of the access carrier frequency band in which the usage right is obtained in advance may be: in addition to the carrier frequency band of any frequency of 3.5 GHz, the priority access layer user PAL And the general authorized access user GAA usually uses a carrier frequency band of 3.5 GHz. The first multi-carrier frequency band determined here is essentially the carrier configuration of the operator, that is, the base station.

405. The first device acquires frequency band information that the user equipment supports carrier aggregation.

In the embodiment of the present invention, the first device acquires the frequency band information of the carrier aggregation supported by the user equipment, that is, after the user equipment sends the frequency band information of the carrier aggregation supported by the user equipment to the first device, the first device acquires the carrier aggregation supported by the user equipment. The frequency band information of the carrier aggregation supported by the user equipment may include, but is not limited to, information about the capability of the user equipment to support carrier aggregation and service parameters.

It should be noted that step 405 can occur at any timing before step 405.

406. The first device determines a second multi-carrier frequency band according to the frequency band information of the carrier aggregation supported by the user equipment and the first multi-carrier frequency band, where the second multi-carrier frequency band is a frequency band used by the user equipment for communication;

In the embodiment of the present invention, the first device determines the second multi-carrier frequency band according to the frequency band information of the carrier aggregation supported by the user equipment and the first multi-carrier frequency band, and the second multi-carrier frequency band is a frequency band used by the user equipment for communication. The carrier aggregation band information supported by the user equipment may include the capability of the user equipment to support carrier aggregation or service parameters and other information.

The method may include: (1) determining that there is an intersection of the multi-carrier frequency band when the capability of the user equipment supporting the carrier aggregation and the first multi-carrier frequency band intersect, or the subset of the multi-carrier frequency band having the intersection is the second multi-carrier frequency band. . (2) The first device determines the second multi-carrier frequency band according to the service parameter and the first multi-carrier frequency band.

(1) It should be understood that, as described above, the first multi-carrier frequency band determined by the base station may be: a multi-carrier frequency band of 1Licensed carrier frequency band and PAL carrier frequency band; 2Licensed carrier frequency band and multi-carrier frequency band of GAA carrier frequency band; 3Licensed carrier Multi-carrier frequency band of frequency band, PAL carrier frequency band and GAA carrier frequency band; multi-carrier frequency band set by 4 PAL carrier frequency band and GAA carrier frequency band.

The carrier aggregation capability supported by the user equipment includes: 1 carrier frequency band supporting the pre-acquisition use frequency band and carrier aggregation capability of the preferential access carrier frequency band; or 2 carrier frequency band and general authorized access carrier frequency band supporting the pre-acquisition use right Carrier aggregation capability; or, 3 supports carrier aggregation frequency, priority access carrier frequency band, and carrier aggregation capability of the generally authorized access carrier frequency band; 4 may also support priority access carrier frequency band and general authorized access carrier Carrier aggregation capability of the frequency band.

Therefore, the second multi-carrier frequency band determined by the base station may be: 1Licensed carrier frequency band and PAL carrier frequency band carrier aggregation; 2Licensed carrier frequency band and GAA carrier configured carrier frequency band; 3Licensed carrier frequency band, PAL carrier frequency band and GAA carrier frequency band carrier Aggregation; carrier aggregation of the 4PAL carrier band and the GAA carrier band.

When the capability of the user equipment supporting carrier aggregation intersects with the first multi-carrier frequency band, it is determined that there is an intersection multi-carrier frequency band, or a subset of the intersection multi-carrier frequency bands is a second multi-carrier frequency band. Exemplarily, the intersection of the capability of the carrier aggregation supported by the user equipment and the first multi-carrier frequency band is {A, B, C}, then {A, B, C} can be regarded as the second multi-carrier frequency band, or {A The subsets of {B, C}, {B, C}, {A, C}, {A}, {B}, and {C} are all considered to be the second multi-carrier band. It should be noted that A, B, and C here represent the meaning of the carrier frequency band, so the writing is only for the sake of simplicity and convenience.

The second multi-carrier frequency band determined by the base station is determined by the capability of the carrier aggregation supported by the user equipment, that is, the capability of the user equipment to support the carrier aggregation is: carrier aggregation that supports the pre-acquisition of the use frequency and carrier aggregation of the preferential access carrier frequency band. Capability, then, the second multi-carrier frequency band determined by the base station for the user equipment is the carrier aggregation of the Licensed carrier frequency band and the PAL carrier frequency band, and the others are similar, and will not be described here.

(2) When the frequency band information of the carrier aggregation supported by the user equipment is a service parameter, the service parameter may include information such as the service type and the service priority. The following describes the service type and service priority.

1 service type, which may be indicated according to different charging standards of different services, and then determining that the first carrier aggregation may be: when the high-charged service is used, the base station selects the multi-carrier frequency band of the licensed carrier frequency band and the PAL carrier frequency band for the UE; For the charging service, the base station selects the licensed carrier frequency band and the multi-carrier frequency band of the GAA carrier frequency band for the UE.

2, service priority, if it is a high-priority service, the base station determines for the UE that the second carrier frequency band can be a multi-carrier frequency band of the Licensed carrier frequency band and the PAL carrier frequency band; if it is a medium/low priority service, the base station determines the second carrier Two carrier The frequency band can be a multi-carrier frequency band of the Licensed carrier frequency band and the PAL/GAA carrier frequency band.
