The highly dense scene to face the future, the proposed vertical a new generation's IEEE802.11 supplementary standard of IEEE, OFDMA (Orthogonal Frequency-Division Multiple Access) technology will be introduced, the use of the OFDMA technology can promote bandwidth resource utilization.Transmission bandwidth is divided a series of subcarrier collection not overlapped being orthogonal by OFDMA technology, and different subcarrier collection is distributed to different websites and is used, to realize that access point can while be communicated with multiple websites.Meanwhile OFDMA technology dynamically provides available bandwidth The website of needs is distributed in source, realizes the Optimum utilization of system resource.According to the difference of data transfer direction, can be divided into again access point to station transmission data be DL-OFDMA (Downlink-OFDMA, downlink OFDMA) technology, it is UL-OFDMA (Uplink-OFDMA, upgoing O FDMA) technology that website, which transmits data to access point,.DL-OFDMA technology can realize access point to multiple websites by occupying the subcarrier collection not overlapped while send data.Equally, UL-OFDMA can realize multiple websites to access point while send data.It is dynamically distributed since the link circuit resources such as subcarrier will be realized, so access point, which needs to inform in advance the resource information that website is distributed, just can be carried out communication before establishing the non-straight connected link based on OFDMA.Resource allocation information can be carried by physical header (PHY Header) and the media access control layer part (Media Access Control, MAC).

The proposed vertical IEEE802.11 supplementary standard of new generation of IEEE will enhance original direct connected link part, further to adapt to the following highly dense scene.A kind of enhanced scheme of direct connected link proposes to dispatch direct connected link simultaneously within the indirectly connected link scheduling period of DL-OFDMA or UL-OFDMA at present, realizes that direct connected link coexists with non-straight connected link, while reducing influence of the direct connected link to non-straight connected link as far as possible.And be also required to access point and send direct connected link resource allocation record in advance, so that direct connected link website can carry out direct-connected communication according to the resource of distribution.Resource allocation object is indicated using the mark of website (such as association identification) and the mark of direct connected link in resource allocation information.But, in order to reduce the length of resource allocation information, the mark of website and the mark of direct connected link can be indicated by truncated method in resource allocation information, such as in IEEE802.11ac standard resource allocation information only distribute the field of 8 bits indicate be originally 16 bits site identity, thus a resource allocation information belongs to an indirectly connected website or the website of direct-connected communication is easy for that ambiguity occurs, and increase additional field or information bit to indicate that this information potential must increase expense, it is disagreed with the length for reducing resource allocation information as far as possible.

Step 102 sends the resource allocation information to website, in order to which the website that the website that the site identity of the indirectly connected linkstation indicates carries out indirectly connected communication or direct connected link mark instruction carries out direct-connected communication.

One website can be direct connected link website or indirectly connected linkstation, and direct connected link website can record according to the resource allocation and carry out direct-connected communication and/or indirectly connected communication.Indirectly connected linkstation only carries out indirectly connected communication according to resource allocation record in the present embodiment scene.

So, the resource allocation of the direct connected link is recorded in the resource allocation record format that the non-straight connected link is multiplexed on format, by resource allocation record in Linktype identification information take the first value range or the second value range indicate resource allocation record be direct connected link resource allocation record or indirectly connected link circuit resource assignment record, the first value range of Linktype identification information is also used to indicate transmission rate information necessary to indirectly connected communication simultaneously, it avoids additionally increasing identification information of the field as Linktype, significantly reduce the length of resource allocation information, improve the utilization rate of bandwidth.

Step 201 receives the resource allocation information that access point is sent.

The resource allocation information is recorded comprising a plurality of resource allocation, and every resource allocation record includes Linktype identification information, link identification information and channel resource information.

Wherein, when the Linktype identification information in a resource allocation record takes the first value range, link identification information described in the resource allocation record includes the site identity of an indirectly connected linkstation, the value of Linktype identification information described in the resource allocation record is used to indicate message transmission rate when the indirectly connected linkstation is communicated with described access point, and channel resource information described in the resource allocation record is used to indicate the indirectly connected linkstation and communicates required channel resource with described access point foundation.

When the Linktype identification information in a resource allocation record takes the second value range, link identification information described in the resource allocation record includes the link identification of a direct connected link, it is the resource allocation record that direct connected link website carries out direct-connected communication that the value of Linktype identification information described in the resource allocation record, which is used to indicate the resource allocation record, and channel resource information described in the resource allocation record is used to indicate channel resource needed for the direct connected link website carries out direct-connected communication.

Second value range can be a value.

Step 202, the processing resource allocation information.

It should be noted that lookup Linktype identification information takes the first value range in the resource allocation information and the link identification information takes after receiving the resource allocation information Value is the resource allocation record of the site identity of the direct connected link website, if finding the resource allocation record that Linktype identification information takes the first value range and the link identification information value as the site identity of the direct connected link website, the channel resource information and access point in resource allocation record is used to carry out indirectly connected communication.And, after receiving the resource allocation information, Linktype identification information is searched in the resource allocation information takes the second value range and the link identification information value to record for the resource allocation of the link identification of direct connected link where the direct connected link website, if finding, Linktype identification information takes the second value range and the link identification information value is the resource allocation record of the link identification of direct connected link where the direct connected link website, direct-connected communication is carried out using the direct connected link distance station point of the direct connected link mark instruction of the channel resource information and the direct connected link in resource allocation record.

So, the resource allocation of the direct connected link is recorded in the resource allocation record format that the non-straight connected link is multiplexed on format, by resource allocation record in Linktype identification information take the first value range or the second value range indicate resource allocation record be direct connected link resource allocation record or indirectly connected link circuit resource assignment record, the first value range of Linktype identification information is also used to indicate transmission rate information necessary to indirectly connected communication simultaneously, it avoids additionally increasing identification information of the field as Linktype, significantly reduce the length of resource allocation information, improve the utilization rate of bandwidth.

Particularly, the present invention is not concerned with website after receiving resource allocation information, not only it had searched direct connected link resource allocation record but also had searched the resource allocation record of two kinds of Linktypes of indirectly connected link circuit resource assignment record, and still looked only for a kind of resource allocation record of Linktype in direct connected link resource allocation record and indirectly connected link circuit resource assignment record.Such as website be known in advance the website this it is scheduled be a kind of resource allocation record that direct-connected communication or indirectly connected communication can look only for Linktype.If website can not find relevant to website resource allocation record, illustrate the direct connected link and non-straight connected link where this received resource allocation information of institute is not related to this website.

The embodiment of the present invention provides a kind of data processing method, it is assumed that applied to WiFi scene as shown in Figure 1, website and access point in the WiFi scene use OFDMA technology, as shown in Figure 5, comprising:

Step 301, access point generate resource allocation information.

To initiate indirectly connected communication and direct-connected communication based on OFDMA simultaneously, access point generates resource allocation information.The resource allocation information be used to indicate direct connected link carry out it is direct-connected communication or non-straight connected link carry out indirectly connected communication needed for physical layer resources, may include direct connected link resource allocation record and indirectly connected link circuit resource assignment record.

Non-straight connected link refers to the accession to a little communication link between website.Non-straight connected link based on OFDMA refers to the communication link carried out data transmission simultaneously with multiple websites using OFDMA mechanism access point.

Indirectly connected link circuit resource assignment record is used to indicate described access point and is carried out indirectly connected communicating the resource distributed by the non-straight connected link between indirectly connected linkstation and described access point.The indirectly connected link circuit resource assignment record includes link identification information, message transmission rate information and channel resource information etc..

Wherein, the link identification information includes the site identity of an indirectly connected linkstation.The message transmission rate information, which is used to indicate between the indirectly connected linkstation and access point, communicates used message transmission rate.The channel resource information is used to indicate the indirectly connected linkstation and communicates required channel resource with described access point.

It should be noted that, the quantity of the message transmission rate for the non-straight connected link supported by system is usually less than the size of message transmission rate information valued space described in the indirectly connected link circuit resource assignment record, and there are the first value ranges and the second value range in the valued space of the message transmission rate information.First value range refers to the valued space that message transmission rate is used to indicate in the message transmission rate information, second value range can be the remaining valued space in the valued space of the message transmission rate information in addition to first value range, it is also possible to the subspace of the remaining valued space, a value being also possible in the remaining valued space.Such as, message transmission rate information field is that 4 bits can indicate 16 kinds of message transmission rates in IEEE802.11ac, its valued space is 0~15, but real system only supports 10 kinds of message transmission rates, therefore the valued space that message transmission rate information field is used only 0~9 in IEEE802.11ac is used to indicate message transmission rate, as described first value range, so described second value range can be the valued space of 10~15 compositions, it is also possible to the subspace of the valued space of 10~15 compositions, is also possible to 10~15 In any value.

Direct connected link resource allocation record is used to indicate the resource that access point is distributed by carrying out direct-connected communication between direct connected link website.The direct connected link resource allocation record includes link identification information, Linktype identification information and channel resource information.The direct connected link resource allocation, which is recorded on format, is multiplexed the indirectly connected link circuit resource assignment record.The direct connected link refers to the link of direct communication between website and website.

Wherein, the link identification information includes the direct connected link mark for identifying a direct connected link.In fact, the direct connected link identification information field is multiplexed link identification information field in indirectly connected link circuit resource assignment record format, it is collectively referred to as link identification information field.The direct connected link is identified, mark of the site identity of a website in the direct connected link as the direct connected link can be used, can also be in the valued space parallel with site identity by access point otherwise allocated, how the value present invention is not concerned with specific direct connected link identification information.Only individually from the point of view of the value of link identification, it will be unable to distinguish relevant resource allocation record and be allocated to a direct connected link or non-straight connected link, therefore the direct connected link resource allocation records and needs to be added the Linktype identification information.

Resource allocation record is the direct connected link resource allocation record or the indirectly connected link circuit resource assignment record to the Linktype identification information for identification.Such as, the Linktype identification information is multiplexed message transmission rate information field described in the indirectly connected link circuit resource assignment record, and it is the resource allocation record that direct connected link website carries out direct-connected communication that the second value range of the message transmission rate information field, which is used to indicate the resource allocation record,.

Due to the format of the indirectly connected link circuit resource distribution information of direct connected link resource allocation record reusable, therefore, resource allocation record has unified format, includes at least link identification information field 21 and message transmission rate/Linktype identification information field 22, as shown in Figure 6.Wherein, identify that resource allocation record is direct connected link resource allocation record or indirectly connected link circuit resource assignment record by the message transmission rate/Linktype identification information field.If message transmission rate/Linktype identification information value is in second value range, determine that the corresponding resource allocation information is the direct connected link resource allocation record；If message transmission rate/Linktype identification information value is in first value range, determine that the corresponding resource allocation information is the indirectly connected link circuit resource assignment record, and data pass Defeated rate/Linktype identification information is still used to indicate the message transmission rate of non-straight connected link.

Step 302, access point send the resource allocation information to website.

So that the website being related to described in the resource allocation information carries out direct-connected communication or indirectly connected communication according to resource allocation record.

Step 303, direct connected link website search the resource allocation record that Linktype identification information takes the first value range and the link identification information value as the site identity of the direct connected link website in the resource allocation information.

The direct connected link website refers to the website for having built up direct connected link, which can also establish non-straight connected link with access point simultaneously.

If finding the resource allocation record that Linktype identification information takes the first value range and the link identification information value as the site identity of the direct connected link website, step 304 is executed.

If not finding the resource allocation record that Linktype identification information takes the first value range and the link identification information value as the site identity of the direct connected link website, step 305 is executed.
