Embodiment

To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the present invention Accompanying drawing in embodiment, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that Described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based in the present invention Embodiment, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its His embodiment, belongs to the scope of protection of the invention.

The embodiment of the present invention is described in further detail with reference to Figure of description.

First, the situation for occurring BSS Color conflicts is illustrated.According to OBSS pairs clashed The difference of this BSS annoyance level, the situation for occurring BSS Color conflicts can be divided into following four situation：

1) AP in the AP and OBSS in this BSS can mutually hear, i.e.,：AP in this BSS Transceiving data is interfered with the AP transceiving datas in OBSS；

2) STA in the AP and OBSS in this BSS can mutually hear, i.e.,：In this BSS AP transceiving datas are interfered with the STA transceiving datas in OBSS；

3) AP in the STA and OBSS in this BSS can mutually hear, i.e.,：In this BSS STA transceiving datas are interfered with the AP transceiving datas in OBSS；

4) STA in the STA and OBSS in this BSS can mutually hear, i.e.,：In this BSS STA transceiving datas are interfered with the STA transceiving datas in OBSS.

For example, it is assumed that the wireless signal of the AP transmittings in BSS can be received by STA or other AP Scope be：Using the AP as the center of circle, the region covered using r by the circle of radius, and the STA in BSS The wireless signal of transmitting can be by AP or other STA scope received：Using the STA as the center of circle, with r The region covered by the circle of radius.I.e.：The maximum communication distance of AP or STA in BSS (communication distance) is r.

The wireless signal that refer to the AP1 transmittings in Fig. 1-Fig. 4, Fig. 1-Fig. 4 in this BSS can be by STA Or the scope that other AP are received is：Using AP1 as the center of circle, the region covered by the circle of radius using r is (i.e. The region that solid line circle is covered in Fig. 1-Fig. 4), OBSS and this BSS overlaps, in OBSS The wireless signals of wireless signal transmission of AP2 transmittings can be by STA or other AP scope received： Using AP2 as the center of circle, (i.e. dashed circle is covered in Fig. 1-Fig. 4 in the region covered using r by the circle of radius Region).

As shown in figure 1, because the AP2 in OBSS is located at using the AP1 in this BSS as the center of circle, with r The region ((i.e. the region that solid line circle is covered in Fig. 1)) covered by the circle of radius, and this BSS In AP1 be located at using the AP2 in OBSS as the center of circle, the region covered by the circle of radius using r is (i.e. The region that dashed circle is covered in Fig. 1), so the AP2 in AP1 and OBSS in this BSS can Mutually to hear.

As shown in Fig. 2 because the STA in OBSS is located at using the AP1 in this BSS as the center of circle, with r The region (i.e. the region that solid line circle is covered in Fig. 2) covered by the circle of radius, and in this BSS AP1 is located at using the STA in OBSS as the center of circle, region (the i.e. Fig. 2 covered using r by the circle of radius The region that middle dotted line circle is covered), so STA in AP1 and OBSS in this BSS can be with Mutually hear.

As shown in figure 3, because the AP2 in OBSS is located at using the STA in this BSS as the center of circle, with r The region (i.e. the region that two-dot chain line circle is covered in Fig. 3) covered by the circle of radius, and this BSS In STA be located at using the AP2 in OBSS as the center of circle, the region covered by the circle of radius using r is (i.e. The region that dashed circle is covered in Fig. 3), so the AP2 in STA and OBSS in this BSS can Mutually to hear.

As shown in figure 4, because the STA2 in OBSS is located at using the STA1 in this BSS as the center of circle, with The region (i.e. the region that dotted line circle is covered in Fig. 4) that r is covered by the circle of radius, and this BSS In STA1 be located at using the STA2 in OBSS as the center of circle, the region covered by the circle of radius using r is (i.e. The region that two-dot chain line circle is covered in Fig. 4), so in STA1 and OBSS in this BSS STA2 can mutually hear.

Separately below to how determining whether that occurring BSS Color conflicts in the case of above-mentioned four kinds, and how The BSS Color conflicts for solving to occur are illustrated.

The basic conception in the embodiment of the present invention is illustrated first.

1) PPDU (Chinese：PLCP protocol Data Units；English：PLCP Protocol Data Unit), Wherein, PLCP (Chinese：Physical layer convergence process；English：Physical Layer Convergence Procedure).The data mutually transmitted between AP and STA in BSS are encapsulated in PPDU.

PPDU structure is as shown in figure 5, PPDU includes three fields：Leading (the PLCP of PLCP Preamble), PLCP (PLCP Header) and MPDU (Chinese：Media access control protocol Data cell；English：MAC protocol data unit) or PSDU (Chinese：PLCP business datum lists Member；English：PLCP Service Data Unit).

Wherein, PLCP include：HE-SIG-A fields and HE-SIG-B fields.HE-SIG-A fields The BSS Color of BSS where AP or STA including sending PPDU.

MPDU or PSDU includes two fields：MAC header (MAC Header) and MSDU (Chinese： MAC layer Service Data Unit；English：MAC Service Data Unit), MAC header field includes hair Send except up MU (Chinese：Multi-user；English：Multi User) other PPDU outside PPDU BSSID (the Chinese of BSS where AP or STA：Basic service set identifier；English：Basic Service Set Identity)。

At present, the structure of up MU PPDU and the HE-SIG-A fields in descending MU PPDU is as schemed Shown in 6, including：Form indicates (Format indication) field, BSS colors (BSS Color) word Section, TXOP duration (TXOP Duration) field, bandwidth (BW) field, HE-SIG-B Number of symbols (Number of HE-SIG-B symbols) field, HE-SIG-B modulation coding mode (MCS of HE-SIG-B) field, check code (CRC) field, afterbody supplement (Tail) field.

In view of related to HE-SIG-B fields in the HE-SIG-A fields in up MU PPDU Partly (i.e. Number of HE-SIG-B symbols domains and MCS of HE-SIG-B domains) be it is reserved, It is not used by, therefore, in the embodiment of the present invention, uses Number of HE-SIG-B symbols domains One or two carrying in MCS of HE-SIG-B domains is sent where up MU PPDU STA A BSS BSSID part, for distinguishing AP or STA in this BSS and the STA in OBSS Whether same BSS is come from.I.e.：The HE-SIG-A for the PLCP heads that the uplink multi-users PPDU is included Field carries a first BSSID part, including：

The field list reserved in the HE-SIG-A fields for the PLCP heads that the uplink multi-users PPDU is included Levy a part of the first BSSID.

Fig. 7 is refer to, Fig. 7 is the PLCP heads included of uplink multi-users PPDU in the embodiment of the present invention The structure of HE-SIG-A fields.Including：Format indication domains, BSS Color domains, TXOP Duration Domain, BW domains, part BSSID domains, CRC domains, Tail domains.Wherein, carried in part BSSID domains Send the BSSID of BSS where a up MU PPDU STA part.

Next, to how to determine the STA in AP or OBSS in the AP and OBSS in this BSS Generation BSS Color conflict, and how to solve the AP in AP and OBSS of the generation in this BSS Or the BSS Color conflicts between the STA in OBSS are illustrated.

Fig. 8 is refer to, the embodiments of the invention provide a kind of method of processing information, is comprised the following steps：

Step 81：First access point AP receives physical layer convergence process PLCP protocol Data Unit PPDU, BSS colors where first AP are first foundation services set BSS colors, the first AP places BSS identifier be first foundation service set identifier BSSID, the PLCP that the PPDU is included The HE-SIG-A fields of head include the 2nd BSS colors, the media access control MAC that the PPDU is included Head includes the 2nd BSSID；

Step 82：First AP determines that the first BSS colors are identical with the 2nd BSS colors, And the first BSSID is different from the 2nd BSSID；

Step 83：The currently used channels of first AP are replaced by other available letters by the first AP Road, or, the first AP by the first BSS color replacements be other BSS colors, it is described other Available channel is different from the channel that the first AP is currently used, other described BSS colors and described first BSS colors are different.

Wherein, step 81- steps 82 are used to determine the AP or OBSS in the AP and OBSS in this BSS In STA occur BSS Color conflict, step 83 is used to solve occur AP and OBSS in this BSS In AP or STA in OBSS between BSS Color conflicts.

Specifically, first, the first AP receives the physical layer convergence process PLCP that STA or other AP is sent Protocol Data Unit PPDU, the HE-SIG-A fields for the PLCP heads that the PPDU is included should comprising transmission The BSS Color of BSS where PPDU STA or AP, the MAC header that the PPDU is included is included Send the BSSID of the BSS where the STA or AP of the PPDU.

Then, the first AP by the BSS Color of the BSS where itself with send the PPDU STA Or the BSS Color of the BSS where AP compare, and the first AP is by the BSS's where itself BSSID is compared with the BSSID of the BSS where the STA or AP that send the PPDU.

If the BSS where STA or AP of the BSS where the first AP itself with sending the PPDU Compare, BSSID is different but BSS Color are identical, then illustrate the first AP with sending the STA of the PPDU Or AP is not in same BSS, but the first AP is with sending the STA or AP of the PPDU using identical BSS Color, therefore, the first AP determine the first AP with send the PPDU STA or AP send out Raw BSS Color conflicts.

If as this BSS the BSS where the first AP will be sent into the STA or AP of the PPDU The BSS at place then can consider the AP or OBSS in the AP and OBSS in this BSS as OBSS In STA occur BSS Color conflict.

Finally, the first AP between the AP in the first AP and OBSS or the STA in OBSS to occurring BSS Color conflict handled, have following two processing modes：

The first processing mode is：First AP by the currently used channels of the first AP be changed to it is currently used Different other channels of channel.

Second of processing mode be：First AP is selected where STA or AP with sending the PPDU Other different BSS BSS Color BSS Color, are used as the BSS of the BSS where the first AP itself Color。

For above-mentioned second of processing mode, the first BSS color replacements are other by the first AP BSS colors, including：

The first BSS color replacements are other BSS colors by the first AP, and notify described the The first BSS color replacements are other BSS colors by the STA in BSS where one AP.It is a kind of Possible mode is：First AP adds in Beacon frames, Probe Response frames or other frames Plus BSS Color Switch Announce fields, then the STA into the BSS where the first AP is wide BSS Color Switch Announce fields are broadcast, or, the first AP is into the BSS where the first AP STA broadcast BSS Color Switch Announce action action frames.Wherein, BSS Color Switch As shown in table 1, BSS Color Switch Announce actions frame definition is such as Announcement field definitions Shown in table 2.

The BSS Color Switch Announcement fields of table 1

The BSS Color Switch Announce action action frames of table 2

In table 1, Element ID are the exclusive identifiers of BSS Color Switch Announcement fields； Length is the length of BSS Color Switch Announcement fields, is worth for 3；BSS Color Switch Mode are used for the pattern for indicating BSS Color Switch；New BSS Color are new for indicating BSS Color；Switch Count are used to indicate the time that new BSS Color change.

BSS Color Switch Announce action action frames shown in table 2 are defined in HT action action frames.Using The basic framework of HT action action frames.Category is the mark of BSS Color Switch Announce action action frames Symbol, for HT action action frames, is worth for 7；HT Action are BSS Color Switch Announce The identifier of action action frame action, can show BSS Color using untapped field in HT Action Switch is acted；BSS Color Switch Announcement fields are with shown in table 1.

STA in BSS where first AP receives BSS Color Switch Announcement fields Or after BSS Color Switch Announce action action frames, according to BSS Color Switch Announce Field updates BSS Color.

Occur BSS Color for the AP in this BSS and the AP in OBSS to conflict, to what is occurred BSS Color conflict solution be：

First AP determines received signal strength according to the PPDU sent by other AP received Indicate RSSI；

If the RSSI is more than predetermined threshold, the first AP is by letter currently used the first AP Road is replaced by other available channels；

Wherein, predetermined threshold can be OBSS PD (Chinese：Detective is surveyed；English：Packet Detection) Value, i.e.,：The corresponding signal intensity of packet in OBSS is more than PD values, then it is assumed that detect packet.

Specifically, the AP in this BSS and OBSS AP can mutually hear, illustrate between the two Interfere serious.AP and OBSS AP in this BSS can realize that the probability of parallel transmission depends on this Relation between the receiving power of AP in BSS and OBSS PD values.

First AP receives the PPDU of other AP transmissions, determines the signal for the PPDU that other AP are sent The receiving power of intensity, as the first AP, then by where the first AP receiving power and other AP BSS PD values compare, if the first AP receiving power is more than the PD of the BSS where other AP Value, then currently used channel is replaced by other available channels by the first AP；If the first AP reception Power is not more than the PD values of the BSS where other AP, then the first AP is by the BSS where the first AP BSS color replacements be other BSS colors.

Occur BSS Color for the AP in this BSS and the STA in OBSS to conflict, to what is occurred BSS Color conflict solution be usually：

First AP selects different from the BSS Color of the BSS where the STA or AP for sending the PPDU Other BSS Color, be used as the BSS Color of the BSS where the first AP itself.

Occur BSS Color for the STA in this BSS and the AP in OBSS to conflict, or this BSS In STA occur BSS Color with the STA in OBSS and conflict, STA in this BSS is notified The AP of STA in BSS occurs after BSS Color conflicts, and the AP of the STA in this BSS is to having sent out The solution of raw BSS Color conflicts is usually：Change BSS Color.

Specifically, due to change BSS Color can be rapidly completed, and change channel be need compared with Long switching time, and 5GHz available channel does not have BSS Color quantity many, and selection space does not have There are BSS Color big, so it is the preferred scheme for solving BSS Color conflicts to change BSS Color.

First, rushed below to how to determine that BSS Color occur for the AP in the AP and OBSS in this BSS It is prominent to illustrate.

If one) AP, in OBSS sends descending single user PPDU, it is determined that in this BSS AP occurs BSS Color with the AP in OBSS and conflicted, including：

First AP determines that the first BSS colors are identical with the 2nd BSS colors, and described First AP determines transmission address TA in the first BSSID and the descending single user PPDU received not Together.

Specifically, on the one hand, the first AP can enter to the MAC header in the single user PPDU that receives Go and parse, obtain and send address, the transmission address of acquisition is the AP places for sending single user PPDU BSS BSSID, then by the BSSID for sending the BSS where address and the first AP itself of acquisition Compare, on the other hand, the first AP can be from the PLCP heads in the single user PPDU received The BSS colors of BSS in HE-SIG-A fields where AP of the acquisition to send single user PPDU, Then by the BSS colors of the BSS where the AP for sending single user PPDU and the first AP itself places BSS BSS colors compare.
