Embodiment 1

[0068] Embodiment 1 of the present invention provides a carrier aggregation implementation method using an unlicensed frequency band, which is applied to the network side, such as figure 1 shown, including:

[0069] Step 101, the network side receives capability information reported by the terminal indicating whether the terminal supports carrier aggregation in licensed frequency bands and license-free frequency bands.

[0070] Step 102: When the capability information indicates that the terminal supports carrier aggregation of licensed frequency bands and license-free frequency bands, determine the currently available carriers in the license-free frequency bands supported by the terminal.

[0071] Wherein, the available carrier may be a carrier not used by other networks.

[0072] Step 103, for the terminal, configure the carrier in the licensed frequency band as the primary carrier, and configure the available carrier as the secondary carrier.

[0073] Step 104: Perform ca...

Embodiment 2

[0118] Based on the same inventive concept, according to the carrier aggregation implementation method using the license-free frequency band provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a carrier aggregation implementation device using the license-free frequency band, which is applied to the network side , whose structure is shown in the Figure 4 shown, including:

[0119] The receiving unit 401 is configured to receive capability information reported by the terminal indicating whether the terminal supports carrier aggregation of licensed frequency bands and license-free frequency bands;

[0120] An available carrier determination unit 402, configured to determine an available carrier in an unlicensed frequency band supported by the terminal and currently in an available state when the capability information indicates that the terminal supports carrier aggregation between a licensed ...

Embodiment 3

[0141] Based on the same inventive concept, according to the method for reporting capability information provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a device for reporting capability information, which is applied to a terminal, and its structural diagram is as follows Figure 5 shown, including:

[0142] The reporting unit 501 is configured to report capability information of whether the terminal supports carrier aggregation of licensed frequency bands and license-free frequency bands to the network side.

[0143] Wherein, the capability information may be used by the network side to perform carrier aggregation configuration on available carriers that the terminal uses the license-free frequency band supported by the terminal and is currently in an available state according to the capability information, where the available carriers are Carriers not used by other networks;

[0144] ...

Abstract

The invention discloses a method for realizing carrier aggregation, a method and a device for detecting carrier availability, comprising: receiving capability information reported by a terminal on a network side indicating whether the terminal supports carrier aggregation in authorized frequency bands and unlicensed frequency bands; and when the capability information indicates the When the terminal supports carrier aggregation of the licensed frequency band and the license-free frequency band, determine the available carrier in the license-free frequency band supported by the terminal and is currently available; and for the terminal, configure the carrier in the licensed frequency band as the main carrier, and configure the available carrier being a secondary carrier; and performing carrier aggregation using the primary carrier and the secondary carrier to communicate with the terminal. By adopting the solution provided by the embodiment of the present invention, when carrier aggregation is performed using the license-free frequency band, adverse effects on the performance of other network systems are avoided, and the performance of carrier aggregation communication performed by the network using the license-free frequency band is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for realizing carrier aggregation, a method and a device for detecting carrier availability. Background technique [0002] The existing Long Term Evolution (LTE, Long Term Evolution) system can only work in the authorized frequency band assigned to the cellular mobile communication system defined by the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) standardization organization, but with the mobile With the rapid development of Internet services, the traffic volume is increasing, and the existing licensed frequency bands are gradually unable to meet the frequency requirements of the LTE system. [0003] The existing LTE system can only work in the licensed frequency band (licensed, the frequency is allocated to fixed users, exclusive) allocated to the cellular mobile communication system. With the shortage of frequenc...
