Problems solved by technology
[0008] (1) Since each allocation of resources requires the transmission of multiple price increase messages, the overhead of the network is increased and the utilization rate of idle TV channels is reduced;
[0009] (2) In this auction method, the resource leasing site has to decide its own bidding strategy according to the duration of the auction process notified by the resource leasing site, so it has considerable complexity

Embodiment
[0101] The resource allocation process of the present invention is further described below through a specific embodiment.
[0102] 1. The rental site sends a resource advertisement message
[0103] refer to figure 1 , the rental site BS1 sends out a CBP packet with a resource advertisement message, that is, the RO-ADV information unit shown in Table 2 is loaded into the MAC payload of the CBP packet, such as Figure 7 shown. Figure 7 Each minimum resource unit BIN that can be leased in is a time slot * a subcarrier, so the values of the SB field and the SCB field in the RO-ADV information element are both 1, and the RST field and the RET field indicate the channel that BS1 will lease resource start time T 开始 and end time T 结束 . The NBR field in the RO-ADV information element = 1, indicating that the number of discontinuous subcarrier blocks to be leased is 1, and the RSS[1] field and RES[1] field respectively indicate Figure 7 The starting subcarrier frequency f in t...

The invention discloses a CBP packet framing structure based on IEEE 802.22 protocol draft and the auction resource distribution method. The invention acquires the channel resource sharing between wireless local area networks. The CBP packet framing structure fills the information unit used for the resource renting and hire in a MAC load and facilitates the transmission of the CBP packet to complete the renting and hire of the channel between the wireless local area networks. When the CBP packet implements the auction resource distribution, the renting site first of all transmits resource advertisement information to the adjacent renting site. The renting site of the corresponding channel resource is needed to transmit the resource request of the renting site and the bid price of the renting site. After receiving all the resource requests and the bid prices, the renting site implements the resource distribution, finally reach a deal price and informs all the renting sites. The conformation of all the renting sites is received and the borrowing token transmits the resource authorization information, and then the auction resource distribution is completed. The invention has the advantages of short auction time and small transmitting times of the CBP packet. The invention can be used for the resource distribution of the wireless local area network.
Description
technical field [0001] The invention belongs to the technical field of communication, and relates to channel resource allocation, specifically a CBP packet frame structure and an auction resource allocation method based on the IEEE 802.22 protocol, which are used for channel resource sharing between wireless area network cells. Background technique [0002] With the development of cognitive radio technology, various standardization organizations and industry alliances have also carried out relevant research, and started to formulate standards and protocols for cognitive radio. The Institute of Electrical and Electronics Engineers IEEE formally established the IEEE802.22 working group in November 2004, which is the first worldwide air interface standardization organization based on cognitive radio technology. Subsequently, the working group carried out a series of work, and released the first draft agreement in May 2006. The protocol IEEE802.22 is also called wireless area n...
