Problems solved by technology

In LAA systems, such short periodic transmissions can cause interference to nearby WiFi and other LAA nodes
Moreover, due to the uncertainty of the occupancy of unlicensed carrier resources, the reference signal must be transmitted discontinuously

Embodiment Construction

[0078] In the embodiment of the present invention, the network side device determines the available channel of the unlicensed carrier according to the available status and availability of the unlicensed carrier channel, and instructs the user equipment UE to measure the available channel, and the UE measures the unlicensed carrier indicated by the network side device. The available channel is measured, and the measurement result is reported to the network side device. Here, the network side device may be a base station, a central base station or a network node.

[0079] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0080] The embodiment of the present invention implements a method for measuring an unlicensed carrier, such as figure 1 As shown, the method includes the following steps:

[0081] Step 101: The network side device determines the available channel of the unlicensed carrier ac...

Abstract

The present invention discloses an unauthorized carrier measurement method. The method comprises the steps of using a network-side device to determine an available channel of an unauthorized carrier according to the available state and the availability of an unauthorized carrier channel, indicating a user equipment (UE) to measure the available channel, using the UE to measure the available channel of the unauthorized carrier indicated by the network-side device, and reporting a measurement result to the network-side device. The present invention simultaneously discloses an unauthorized carrier measurement device.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method and device for measuring an unlicensed carrier. Background technique [0002] The Long Term Evolution / Long Term Advanced (LTE / LTE-A, Long Term Evolution Advanced) system is a fourth-generation mobile communication standard formulated by the 3GPP (The 3rd Generation Partnership Project) organization. LTE supports multiple bandwidth allocations: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, etc. Spectrum allocation is more flexible. LTE currently mainly works on authorized spectrum, and the frequency bands selected in different regions are also different. The North American network plans to use 700 / 800 and 1700 / 1900MHz; the European network plans to use 800, 1800, 2600MHz; the Asian network plans to use 1800MHz and 2600MHz; the Australian network plans to use 1800MHz. [0003] In order to support a wider frequency band, LTE-A introduces Carrier Aggregation (CA, Carrier...
