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

Improve switching frame reactive methods/approaches and system in the WLAN

Technical field

(wireless local area network WLAN), more particularly, the present invention relates to a kind of reactive method and system that are used for improving at this WLAN exchange of management, control or Frame to the present invention relates to a kind of WLAN.

Background technology

Among IEEE 802.11WLANs, one access point (access point, AP) or a platform (STA) be can use and management frame guide some management function, the example of those management frames has, connection request (Association Request), connection response (Association Response), reconnect request (Reassociation Request), reconnect response (ReassociationResponse), probe request (Probe Request), and probe is responded frames such as (Probe Response).

IEEE 802.11e utilizes new management frames to extend IEEE 802.11 standards, what some in these new management frames were claimed is action action frame (action frame), those action action frame then are to be used to guide some function, for example, service quality (QoS) Business Stream (traffic stream) is set up, directly link and set up, block confirms that (ACK) sets up, or fellow, the example of those action action frame comprises, increases service traffics requests (Add Traffic Stream (ADDTS) Request), the ADDTS response, directly link the request of setting up (DLS), the DLS response increases block and confirms (ADDBA) request, increases block ACK and responds, the deletion block is confirmed (DELBA) request, or the fellow.

At present, IEEE 802.11n extend be proposed to be used in reach higher defeated inertia (higherthroughput, HT).In the motion of IEEE 802.11n, new action action frame is imported into, to be used to provide transmission mode and channel information feedback, wherein, the transmission mode feedback makes a reception platform to notify and is in transmits platform for present channel condition for one of better model, the selection of this special pattern is determined by this reception platform, but, this transmission platform can, or can not use this special pattern, all all depend on its ability, and, one reception platform also is can refuse politely a better model is provided, in addition, the channel information feedback provides one to allow a transmission platform can learn mechanism at being seen this accurate passage of this reception platform, this information then is the part that can be used as a calibration (calibration), and then be used to adopt the interact system of (channel reciprocity) of passage, or directly used as the passage feedback, receiving platform as for one then is that a complete passage assessment may be provided, an or null response (null response).The example of those IEEE 802.11n action action frame has, mode request (Mode Request), mode response (Mode Response), multi-input multi-output channel request (multiple-input multiple-output (MIMO) Channel Request), and MIMO channel response frames such as (MIMO Channel Response).

Management frames (comprising action action frame) can be broadcasted, or multicast (multicast) is to a plurality of responsors, (for example, via a beacon frame), perhaps, alternatively, can broadcast (unicast) to one special (single) responsor by single-point, (for example, the ADDBA request, the ADDBA response, mode request, mode response, the mimo channel request, and mimo channel response), wherein, when a management, or action action frame is when being broadcast to a specific response device by single-point, these IEEE 802.11 standards are to need this responsor to confirm that by sending an ACK package it receives so frame, on the other hand, if should manage, or action action frame is broadcasted, or multicast is when being a plurality of responsor, and these IEEE 802.11 standards do not need those responsors to confirm to receive so frame.

Fig. 1 one is used for beginning managing between a device 102 and the responsor 104 or accompanying drawing that a signal of the known procedure 100 of action action frame exchange sends together.This initiator 102 is can be to needs corresponding to those IEEE 802.11 substandard race conditions (contention), or the wireless medium of some delays of access delay carries out access, and, can (for example send an action action frame, one mode request frame) to this responsor 104 (step 112), and after correctly receiving this action action frame, 104 of this responsors be can access this (for example need some delays equally, corresponding to a short interFrameGap (short inter-framespacing, SIFS) delay) also can send the wireless medium (step 114) of an ACK package to this initiator 102, then, this responsor 104 can (for example be prepared an action action frame, one mode response frame), comprise the data that this initiator 102 is asked, and then the ground access should be because competition, or access delay and need the wireless medium of some delays, and send this action action frame to this initiator 102 (step 116), at this moment, this delay may in fact can be very long, because might other platform also carry out packet-switched between at the same time, therefore, this responsor 104 just may be willing to these medium of ground access as it, then, correctly after this responsor 104 receives this action action frame, this initiator 102 will access this need some delays equally (typically, one time durations) wireless medium corresponding to this SIFS, and send an ACK package to this response device 104 (step 118).

Among this known procedure 100; because this responsor 104 at first must send an ACK package (step 114); then for this wireless medium of access to send this response frame when the step 116; must cause a competition; or access delay; therefore; exchange is management so; or the reactivity of action action frame will be slow comparatively speaking; and management so slowly; the action action frame response just may reduce the performance of this WLAN; because this information possibly can't be effective; or it is proper in its time of sending; for example; because the transmission mode feedback makes this responsor 104 specifically to state clearly; or point out and the relevant information of this initiator transmission; comprise a data transfer rate; one modulation and coding planning (modulation and coding scheme); spatial flow in MIMO (spatial stream) quantity; and guard interval (guard interval); therefore; so information should exchange as quickly as possible; yet; under the planning of known technology, so the exchange of information but may be subjected to postponing considerably.

Therefore, have and need one in order in a mechanism of carrying out the exchange of those management or action action frame in very between short-term.

Summary of the invention

The present invention is relevant to a kind of method and system that are used for improving the exchange reaction of WLAN management and control frame.One initiator can send a frame (action, management, control, or Frame) to a response device, and after correctly receiving this frame, this responsor is can send a response frame to this initiator, confirm (ACK) package to replace direct transmission one, and be preferably, this responsor can carry out access to this wireless medium, to send this Echo Frame in a short interFrameGap (SIFS).By this planning, one is relevant to the long delay system that must compete this wireless medium in order to send this response frame can be avoided, therefore, the reactivity of this feedback mechanism and promptness just can obtain to strengthen significantly, and wherein, this response frame can be born on another package or with another package and be condensed together.

After this, proper noun " initiator (initiator) " and " responding device (responder) " are to comprise, but be not limited to, one user's equipment (user equipment, UE), one wireless transmission/receive unit (wireless transmit/receive unit, WTRU), one moves platform, a fixing or moving user unit, a calling set, one Node B (Node-B), one base station, a positioner (site controller), an access point or any other kenel device that can in a wireless environment, operate.

Feature of the present invention can be incorporated among the integrated circuit (IC) or being established in one comprises among the circuit of many interconnecting components.

Fig. 2 is for responding device 204 and (also be known as a signal transmission figure of the program 200 of advancing to move the action action frame exchange between the recipient (recipient) according to of the present invention one device 202 (also being known as originator (originator)) and that is used for beginning together, wherein, this initiator 202 is for grasp a transmission opportunity (transmit opportunity for a moment, TXOP), and can comprise polymerization physical layer protocol data unit (aggregate physical layer protocol data units by one, A-PPDUs), or the frame exchange sequence of polymerization control frame and transmit the communication entity of one first frame, as for 204 of this responsors for comprise that with one the frame exchange sequence of A-PPDUs and polymerization control frame responds the communication entity of this initiator 202 for a moment.This initiator 202 can send an action action frame (claim frame normally, a mode request frame for example) to a responsor 204 (step 212), and after correctly receiving this action action frame, replace and directly send an ACK package, this responsor 204 is to send a response action action frame (for example, a mode response frame) (step 214).After this, the present invention will narrate as reference with action action frame, but, what should note then is, the present invention equally also is the frame that goes for any kenel, for example, management frames, control frame, Frame or fellow, and this claim frame and this response frame can be the frames of different kenels.

Be preferably, this responds device 204 these wireless mediums of meeting access, to send this response action action frame in during between a period of time corresponding to a SIFS, then, this initiator 202 can send an ACK frame after short the delay, be preferably, corresponding to this SIFS (step 216).According to the present invention, must compete this long delay of this wireless medium when closing the step 116 that is connected among Fig. 1 and can be avoided, therefore, the reactivity of this feedback mechanism and promptness will obtain to strengthen significantly.

Perhaps, alternatively, also can be born on an ACK package, another management or control frame or a data packet in this response action action frame of step 214, perhaps also can be and this ACK package, another management or control frame or a data packet phase-polymerization.When this ACK package is born or during polymerization, this is because of responding this origination action frame (that is, this mode request frame) and the ACK package that is sent out can't be eliminated, but can send with another frame.

This signal transmitter system of the present invention can be by default value, or according to both are shared for this initiator 202 and this responsor 204 one creation facilities program (CFP) carried out, under this situation, extra field is can be comprised in an action action frame (to comprise a management frames, one control frame, one Frame, or fellow) among, to indicate a preferable signal transmitter system, for example, this initiator 202 (for example can send a claim frame, one mode request frame, one MIMO channel request frame, one MCS asks (MCS request, MRQ) frame, one channel condition information (channel state information, CSI) claim frame, one calibration beginning (calibration star) frame, one transmit antenna is selected sounding claim frame (transmitantenna selection sounding request frame), an or train request (trainingrequest, TRQ) frame, or fellow), it then is to be provided with to be used to indicate this responsor 204 will how to be responded the newer field of this claim frame by expection in this claim frame.

Those new fields include, but not limited to an ACK policy field, one request identification number code field, a response time policy field, and a polymerization policy field, at least one of them, and wherein, this ACK policy field can indicate this responsor 204 whether to need to send an ACK package.

This request identification number code field comprises a request identification number, one response frame then is to use one similarly to ask the identification number code field, and its numerical value is can be corresponding to this request identification number in this claim frame, perhaps, alternatively, when if this response frame sends as much as possible, this request identification number code field in this response frame can be set at a special numerical value, this will in after detailed explanation is arranged.

This response time delay policy field can indicate this responsor 204 whether by expection to send immediately a response frame to this initiator 202 (that is, SIFS) or, will one than this short postpone for long special time delay scope among or during at these responsor 204 times selected points (that is, active supplier (unsolicited)).

This polymerization policy field system can indicate this responsor 204 whether by expection to send this born on another package or with the response frame of other package phase-polymerization, for example, one ACK package, one management or control package, one data packet, or the package of other kenel, and a plurality of management frames can be aggregated among the package.At this, when a MMPDU is sent independently (that is, be not the part of a polymerization), be to use a simple ACK, and when one or more MMPDUs system sends as the part of a polymerization, then just can use a block ACK (block ACK, BA).

When this ACK policy be chosen as can comprise one respond to this response frame ACK the time, then just can implement ensuing planning.MMPDUs can utilize one to be not that each responsor is all unique independent counter and is assigned with sequence numbering (sequence numbers by this initiator 202, SNs), and, also can be used to broadcasting/multicast frame, and be used for non-QoS data subtype attitude frame (non-QoS-datasubtype frames).According to the present invention, management frames is can utilize a pair of each responsor to be all unique new different SN counter and sort, perhaps, and alternatively, management frames can utilize identical SN counter to sort, and is the same as these data that condense together with management frames.Selection in addition is, this is identical be used to distribute SNs to the IEEE 802.11e method of management frames be to be used, and, this responsor 204 can not rearrange management frames, this is because interval among the S Ns that those received and the frame that can't be lost in order to identification clearly by this responsor 204, therefore, this initiator 202 only need store the copy of those management frames by stating clearly among this ACK policy field, obtains to confirm or till they expire up to their.

(block ACK request, BAR), this ACK policy field of the MMPDU that this is new can be explained to become a BAR to be relevant to the block ACK request that is used for management frames.Alternatively, a different BAR Medium Access Control (MAC) Protocol Data Unit (MAC protocol data un it who is used for management frames, MPDU) can be used as a polymerization (that is, this comprises the polymerization of 2 BAR frames: one is used for Frame, another is used for management frames) a part and sent, perhaps, alternatively, this BAR MPDU form can be extended to comprises that one is partly extra, to be used for management frames (that is this comprises a polymerization with the two-part BAR frame that is respectively applied for this management frames and Frame).

Relevant for a BA package, the one different BA MPDU system that is used for management frames can be used as a polymerization (that is, this comprises the polymerization of 2 BA packages: one is used for Frame, another is used for the part of management frames and is sent, perhaps, alternatively, a known BA MPDU form system can be extended to comprises that one is partly extra, with in order to confirm management frames (that is this comprises a polymerization with the two-part BA that is respectively applied for this management frames and Frame).

Relevant for this BA that supports management frames and the form of BAR package, those BA and the BAR package that are used for management frames can be identical, or be similar to known frame format, and, can utilize one, or special field distribution and identification in addition clearly, this BA and BAR then are (the starting sequence number of sequence numbering at the beginning that can use a bit mapped graphics (bitmap) to be followed, SSN) notion, wherein, if a position n of this BA bit mapped graphics is set at 1 o'clock, then it is to determine that one has the reception that a sequential control numerical value is equal to the MPDU of BA SSN+n, moreover, if a position of this BA bit mapped graphics is set at 0 o'clock, then it is indication, one has the MPDU that MPDU sequential control numerical value equals (BA SSN+n) is not successfully received as yet, typically, those cohesively managed frames probably can have the SNs of increase, when being in those cohesively managed frames and among SNs, having the situation of a large-spacing (for example, frame that polymerization is transmitted again and new frame), a plurality of BAs can be used, the management frames that each aggregate acknowledgements one is different, or a plurality of frames, for example, if this bit mapped graphics (for example has a predefined full-size, 16), and those cohesively managed frames have the different order number more than 15, then they also can't be confirmed among this identical bit mapped graphics, and, another BA frame is necessary that this BA and BAR system may simply be each management frames of considering and list this SN.

The MQR frame, the MCS feedback (MCS feedback, MFB) frame, and train request (Training Request, TRQ) frame comprise the field that those are new, narrate as an example at this.Yet, should be noted that any other management, control or Frame can comprise the frame that these are new, to strengthen the reactivity of those packages of exchange.

Those MRQ frames are the management frames of kind HT.This MRQ frame is in order to ask the MCS feedbacks from a responsor 204, and this MRQ frame, except a MCS request field, as shown in the table 1, then be to comprise an ACK policy field, one request identification number code field, one response time policy field, an and syndication format field, at least one of them, wherein, this ACK policy field be can be set at " non-ACK (No-ACK) " (that is, require a direct MFB frame response), or " ACK " (that is, require an ACK package), when if this MFB package is contemplated to one time, this request identification number code field can be set at a request identification number, when perhaps if this MFB package sends as much as possible, then be set at " 0 ", this response time policy field be set at " immediately " (that is, SIFS), " delay ", or " initiatively providing ", if should be when being set at " immediately " response time, this responsor 204 be can by the expection to send immediately a MFB frame (that is, among the SIFS scope), if should the response time policy be when being set at " delay ", this responsor 204 is can be expected to send this MFB frame in this time of delay of stating clearly, when if " initiatively providing " should the response time policy be provided, then this responsor 204 can send this response at the time point that this responsor 204 is selected, this syndication format field can be set at " polymerization Medium Access Control (MAC) Protocol Data Unit (A-MPDU) ", " RIFS-PPDU ", or " non-polymeric (No-Aggregation) ", when if this syndication format field is set at " A-MPDU ", this responsor 204 and this initiator 202 are will be sent an A-MPDU by expection, when if this syndication format field is set at " RIFS-PPDU ", this responsor 204 and this initiator 202 are will be utilized RIFS to send a plurality of MPDUs by expection, but may produce an A-MPDU, when if this syndication format field is set at " non-polymeric (No-Aggregation) ", this response device 204 and this initiator 202 be can be expected this MFB frame of not polymerization.As another selection, when if this syndication format field is not comprised among this MRQ frame or this MFB frame, then do not needing under the syndication format field thus and the situation of being indicated by its other party, this polymerization system can be carried out when this responsor 204 or initiator 202 independent decisions.
