Embodiment 1

[0084] Such as image 3 As shown, the resource allocation method of the wireless backhaul link in this embodiment is specifically described as follows:

[0085] Step 101: CCP obtains TVWS information in TVDB (that is, information on TV band spectrum resources not occupied by TV band authorized services), including but not limited to available channels (including working frequency and bandwidth), coverage, and possible duration and its maximum allowable transmit power; CCP maintains available TVWS information based on the TVWS information obtained and the system’s use of TVWS spectrum resources stored in the CCP (hereinafter also referred to as TVWS usage information), that is, not used by the system Information on TVWS spectrum resources used;

[0086] Wherein, the way for the CCP to obtain TVWS information may include one of the following ways or any combination thereof: the CCP periodically accesses the TVDB, or the CCP accesses the TVDB as needed, or the TVDB actively noti...

Embodiment 2

[0097] Such as Figure 4 As shown, the resource allocation method of the wireless backhaul link in this embodiment is specifically described as follows:

[0098] Step 201: The CCP obtains the TVWS information in the TVDB, and maintains the corresponding available TVWS information in combination with the information about the TVWS being occupied by the system stored in the CCP;

[0099] Wherein, the way for the CCP to obtain TVWS information may be that the CCP periodically accesses the TVDB, or the CCP accesses the TVDB as needed, or the TVDB proactively notifies the CCP, or a combination thereof.

[0100] Step 202: The AP is turned on and works in the original licensed spectrum;

[0101] Step 203: AP reports information, including but not limited to maximum transmit power, supported working frequency bands, location information, capabilities of access terminals, etc.;

[0102] Step 204: According to the information reported by the AP, if the BS has reserved TVWS spectrum re...

Abstract

The invention discloses an initial configuration method and an initial configuration device for a wireless backhaul link. The method comprises the following steps of: starting an access node, and reporting information to a base station by using an original authorized frequency spectrum; and reconfiguring a wireless backhaul link between the base station and the access point according to a TVWS (Television White Spectrum) resource distributed by a system by using the base station, and switching the wireless backhaul link onto the distributed TVWS resource. According to the method and the device, the resource distribution problem of the wireless backhaul link is solved, and the volume or service quality of a wireless access link is not influenced simultaneously.

Description

technical field [0001] The present invention relates to the technical field of wireless communication and cognitive radio, and more specifically, to a method and device for initial configuration of a wireless backhaul link. Background technique [0002] For LTE (Long Term Evolution, long-term evolution) technology or LTE-A (Long Term Evolution-advanced, evolved long-term evolution) technology, the current AP (Access Point, access node) mainly includes the following types: enhanced Macro cell base station (enhanced Node Base Station), relay (Relay), pico cell base station (Femto NB), micro cell base station (Pico NB) and home base station (home NB). Some of these access nodes can be directly connected, and the link between the access nodes that can be directly connected is called a backhaul link (backhaul link). [0003] The backhaul link may be wireless in LTE / LTE-A, such as the following scenarios: remote areas, coverage of temporary hotspot areas, disaster relief periods,...
