Abstract

A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action, management, control or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.

Description of the Invention: [Technical Field] The present invention relates to a wireless area network (WLAN). More specifically, the present invention relates to a method for A method and system for improving the responsiveness of exchange management, control, or data frames. [Prior Art] Among IEEE 802.11 WLANs, an access point (AP) or a station (STA) uses a management frame to guide certain management functions. Examples of such management frames are , Connection request (Ass〇ciati〇n Request) 'Association Response, Reassociation Request, Reconnect Response (Reass〇dati〇n

Response)，探針請求（pr〇beRequest)，以及探針回應（pr〇be Ruponse)等訊框。 IEEE 802.lie乃是利用新的管理訊框來延伸正EE 標準，這些新的管理訊框中的一些被稱之為動作訊框（acti〇n frame)，而5亥荨動作訊框則是被用於引導某些功能，例如，服務品質（QoS)業務流（traffic stream)建立，直接連結建立，區塊確認（ACK)建立，或是類似者，該等動作訊框的實例包括’增加業務流量請求（Add Traffic Stream ( ADDTS ) Request) ’ ADDTS回應，直接連結建立請求（DLS)，DLS回應，增加區塊確認（ADDBA)請求，增加區塊ACK回應，刪除區塊確認（DELBA)請求，或是類似者。 201004224 曰目前，IEEE 8〇2.iin延伸已經被建議用於達成較高的輸慣量 Oiigher throughput，HT)。在 IEEE 802.11η 的提案中，新的動作訊框被導人’以用於提供傳輸模式以及通道資訊回饋，其中’傳輸模式回饋係使得一接收站自能夠通知處於對目前之通，條件而言為較賴式的—傳輸站台，而雜職式的選擇則是由該接收站台所加以決定，不過，該傳輸站台係可以、或是可以不使用該特別的模式，一切都取決於其能力，並且，一接 ^ 料台也是可_域供—較健式，糾，通道資訊回饋係提供了 -讓-傳輸站台㈣學習在該接㈣台所見之該精痛通道的機制，而此資訊則是可以被使用作為一校準 (calibration)的一部分，進而用於採用通道相互作用（channel reciprocity)的系統，或是被直接使用作為通道回饋，至於一接收站台則是可能會提供一完整的通道評估、或是一空回應 (null response)。該等IEEE 8〇211n動作訊框的實例有^模式請求（Mode Request) ’ 模式回應（M〇de Resp〇nse)，多輸入 (multiple - input multiple - output (ΜΙΜΟ) I Channel Reiluest)，以及 ΜΙΜΟ 通道回應（MIM〇 ChanndResponse), probe request (pr〇beRequest), and probe response (pr〇be Ruponse) and other frames. IEEE 802.lie uses the new management frame to extend the EE standard. Some of these new management frames are called acti〇n frames, while the 5 荨 action frame is Used to guide certain functions, such as quality of service (QoS) traffic flow establishment, direct link establishment, block acknowledgment (ACK) establishment, or the like, examples of such action frames include 'increase Add Traffic Stream (ADDTS) Request ADDTS Response, Direct Link Setup Request (DLS), DLS Response, Add Block Confirmation (ADDBA) Request, Add Block ACK Response, Delete Block Confirmation (DELBA) Request Or similar. 201004224 曰 Currently, the IEEE 8〇2.iin extension has been suggested for achieving higher inertia (Oiigher throughput, HT). In the IEEE 802.11n proposal, a new action frame is used to provide a transmission mode and channel information feedback, where the 'transmission mode feedback system enables a receiving station to be notified that it is in the current state, in terms of conditions. For the more efficient transmission station, the choice of miscellaneous is determined by the receiving station. However, the transmission station can or cannot use this special mode, and everything depends on its capabilities. Moreover, a receiving station is also available for _ domain supply - a more robust, corrective, channel information feedback system provides a - let-transmission platform (four) to learn the mechanism of the painful channel seen in the (four) station, and this information is Can be used as part of a calibration, used in systems with channel reciprocity, or used directly as channel feedback, as a receiving station may provide a complete channel evaluation Or a null response. Examples of such IEEE 8〇211n motion frames are Mode Request 'Mode Response' (M〇de Resp〇nse), Multiple Input - Output (ΜΙΜΟ) I Channel Reiluest, and ΜΙΜΟ Channel response (MIM〇Channd

Management frames (including action frames) can be broadcast, or multicast to multiple responders (for example, via a beacon frame), or, alternatively, can be unicast (unicast) ) to a special (single) responder (eg, ADDBA request, ADDBA response, mode request, mode response, channel request, and MIM0 channel response), where a management, or action frame is unicast to A special responder, the ^ee 5 201004224 802.11 standard would require the responder to acknowledge receipt of such a frame by sending an ack packet. On the other hand, if the management or action frame is broadcast, Or when the multicast is a plurality of responders, the pressure does not require the responders to acknowledge receipt of such a frame. The ...fi map is - used for the conventional program between the first starter 1〇2 and the responder 1〇4, the line g or the action 3 cans of the father - the signal transmission pattern = the initiator 1 ( 2) will need to respond to the mEE黯u standard t, condition (ecmtentiGn), or access delay - some delay of the wireless media dice 'and' will send a motion frame (for example, a mode Request frame) to the response 104 (step 112), and after correctly receiving the action frame, the responder 104 will access the same delay - for example, corresponding to a short interval (cutting framespng, measured) delay = and will send a woven packet to the initiator to withdraw the wireless media (step), the receiver, the responder 1 〇 4 will prepare a motion frame (for example, - box i' Included, the data requested by the initiator 102, and then again, the delay or delay of the wireless media, and the action frame to the initiator (step 116). The delay may be = the upper wire, because it is possible that the other _ station is also carrying out the packet transfer at the same time. Can not access the media as desired, after the 12 1G4 receives the _ frame, the starting café also needs some delay (typically, corresponding to the crying ΓΜ / 曰 muscle) of the wireless media, and send An ACK packet is sent to the back library (step 118). In the "Hai K know program K) ' 'Because the responder 1〇4 must first send the 201004224 - ACK packet (step 114), and then in order to access The wireless medium sends the response frame at step 116, which must be in a state of competition, or access delay. Therefore, the exchange of such management, or the motion frame response is relatively slow, and so slow. Management, action frame response may reduce the performance of the WLAN, because the information may not be valid or timely when it is delivered. For example, 'the responder' can be enabled by the transmission mode feedback.

This kind of information should be exchanged as quickly as possible. However, under the planning of the prior art, the exchange of such information may be considerably delayed. Therefore, there is a need for a very A mechanism for performing such management or exchange of action frames in a short period of time. SUMMARY OF THE INVENTION The present invention is directed to a method and system for improving the management of a WLAN and controlling the exchange responsiveness of a pivot. The system sends a frame (action, management, control, or data frame) to a responder, and after receiving the frame correctly, the responder sends a response frame to the initiator to Instead of sending an acknowledgment (ACK) packet directly, and preferably, the responder accesses the wireless medium to transmit the response frame within a short inter-frame interval (SIFS). By this planning, a long delay system that must compete for the wireless medium in order to transmit the response frame can be avoided, and therefore, the feedback frame 7 201004224 can be carried together. The reactivity and timeliness of the system can be simply taken care of, and the package is above or combined with another package. [Embodiment] and "Responder

Hereinafter, the proper noun "initiator" includes, but is not limited to, the features of the present invention may be incorporated into an integrated circuit (IC) or constructed to include a plurality of mutual Connected to the circuit of the component. Figure 2 is for use in an initiator 2〇2 (also known as a 〇riginator) and a responder 2〇4 (also known as a recipient) in accordance with the present invention. A signal transmission pattern between the program 2 of the action frame exchange process, wherein the starting If 2G2 system is - will grasp the transmission opportunity (TX0P), and will include a polymer layer The communication entity of the first frame is transmitted by the aggregation physical layer protocol data units (A_PPDUs) or the frame exchange order of the aggregation control frame, and the responder 204 is included for one time. A_ ppDUs and the communication frame of the hydration control frame are returned to the communication entity of the initiator π]. The initiator 202 sends an action frame (usually a request frame, for example, 201004224, such as a request message) Block) to a responder 2〇4 (step 212), and after correctly receiving the action frame, instead of directly transmitting an ACK packet, the responder 204 will send a response action frame (eg, a mode) Responding to frame X, step 214). Hereinafter, the present invention will be described with reference to the motion frame, but it should be noted that the present invention is also applicable to any type of frame, for example, a management frame, a control frame, The data frame, or the like, and the request and the gamma should be shot in different types of frames. Preferably, the responder 204 accesses the wireless medium to correspond to a = FS. The response action frame is sent during the time period, and then the initiator 202 sends an ACK frame after a short delay, preferably for the SIFS (step 216). According to this (4), it is related to The long delay that must be competed for the wireless medium when the steps in the figure are called is avoided, so the feedback machine _ reactivity and timeliness will be strengthened. \ Or, alternatively, The response action frame of step 214 may also be carried on the -ACK packet, another management or control frame, or a number, packet, or may be associated with the ACK packet, another management or control , frame, or - data packet aggregation. When the general package is backed up, the cause should start the action frame (that is, the mode request frame) === The following signal transmission mechanism of the present invention can be used by the preset value. The starter 2〇2 and an established j shared by the responder, Tsukisaki, are executed. 'In this case, the extra_bit will be included in the action frame 9 201004224 (including a management frame, a control message) In the frame, a data frame, or the like, to indicate a preferred signaling mechanism, for example, the initiator 202 can send a request frame (eg, a mode request frame, A channel request frame, an MCS request (MRQ) frame, a channel state information (CSI) request frame, a calibration star frame, and a transmission antenna selection request A transmitter antenna selection sounding request frame, or a training request (TRQ) frame, or the like, and is provided in the request frame for indicating the responder 2〇 4 How is expected to return to the new position should be stopped requesting information box. The new fields include at least one of 'but not limited to, an ACK policy block, a request identification number block', a response time policy field, and an aggregation policy block, and wherein The ACK policy block will indicate whether the responder 204 needs to send an ACK packet. The request identification number block includes a request identification number, and a response frame uses a similar request identification number block, and the value corresponds to the request identification number in the request frame. Or, alternatively, if the response to the health may be issued by the hometown, the request identification number block in the coffee answer box can be set to a special value, which will be followed by There are detailed explanations. . The response to the B defensive delay policy field will indicate whether the responder is expected to be sent immediately - the response frame to the initiator 2〇2 (ie, chat), ^, to be The short delay is in the long specific time delay range, or at the time point selected by the responder 204 (ie, the active provider 10 201004224 (unsolicited)). The aggregated political table blocker indicates the response. Whether the device 204 is expected to send a response frame that is carried over the other packet or aggregated with other packets, for example, an ACK packet, a management or control packet, a data packet, or other type' % of the packets, and multiple management frames can be aggregated in one package. Here, when an MMPDU is transmitted independently (that is, not part of an aggregation), a simple ACK is used, and when one or more MMPDUs are transmitted as part of an aggregation, A block ACK (BA) can be used. § »Hai ACK Policy is selected to include an ACK to the response frame, then the next plan can be implemented. The MMpDUs system utilizes a separate counter that is not unique to each responder, and is assigned a sequence number (sequence dish she (10), SNs) by the initiator 202, and will also be used for broadcast/multipoint Broadcast frame, and for non _ Q 〇 S data subtype frames. According to the present invention, the management frame can be ordered by using a new different sn count 5| which is unique to the parent responder, or alternatively, the management frame can utilize the same SN counter. Sorting is just like the data that is aggregated with the management frame. Another option is that the same method used to assign the view to the management frame 802.11e method will be used 'and the responder will not rearrange the management frame, because the scale is connected (four) SNs The towel is separated and the benefit is responded to by H 204 to clearly identify the missing frame. Therefore, the copy only needs to store a copy of the ^ frame by placing it in the ACK policy block until They are confirmed or they expire. - 11 201004224 relates to the block ACK request ' BAR' for the management frame. The ACK of the new MMpDU can be interpreted as _ Bar. Alternatively, a different MAC protocol data unit (MPDU) for the management frame can be used as an aggregation (ie, an aggregation of 2 BAR frames: - Used for the development of the data frame 'another part of the management frame', or 'both-the ground'. The BARMPDU format can be extended ^include-extra part, about the management frame ( That is, the inclusion includes a polymerization of a BAR frame having a tool for the management of the § can and the two portions of the data frame. Regarding a BA packet, a different BAMpDU system for managing frames can be used as an -aggregation (that is, an aggregation of 2 BA packets: one for data betting - another - finer than management) Pure delivery, or, alternatively, a conventional BAMpDU format can be extended to include an additional portion of the rib-acquisition management miscellaneous (ie, the inclusion of one has separate for the management frame and data) The aggregation of the two parts of the frame BA.) Regarding the format of the BA and BAR packets supporting the management frame, the BA and BAR packets used for the official frame may be the same or similar The known frame format 'and can be explicitly identified by using a bit, or a special field assignment, and the BA and bar can be started with one of the bitmaps.
