Abstract

A method for addressing groups of stations in a wireless communication system begins by assigning the stations in the system into a number of groups. A group identifier is signaled to each station andthe group identifier is indicated in a frame for each group that has data in the frame. The addressing method can be applied to power savings for the station, wherein the station enters a power savin g mode if the group identifier for the station is not present in the frame.

Description

Efficient addressing and power saving method and system in the wireless system
Technical field
The present invention relates to wireless communication system.More especially, the present invention relates to through enhanced dedicated channel (E-DCH) control transmission method and device.
Background technology
Frame is integrated and the frame burst is proposed mechanism for strengthening two of WLAN (WLAN) system effectiveness.The 802.11n that is considered of this mechanism is extended for the 802.11 WLAN standards that can facilitate than the high production Wireless LAN device.TGnSync and WWISE propose all to consider that all kinds of frames are integrated and frame burst scheme.
Fig. 1 shows TGnSync, and the dissimilar frames that WwiSE or both propose are integrated and frame burst scheme.Integrated scheme roughly can be done differentiation according to the grouping part of its integration.
Medium access control (MAC) service data unit (MSDUs) is integrated (100) can integrate one or more medium access control service data units 102 to form an integration medium access control service data unit (A-MSDU) 104, and each medium access control service data unit is separated by sub-frame header 106.Medium access control header 108 is added into integrates medium access control service data unit to form single medium access control protocol data cell (MPDU) 110.
Medium access control protocol data cell is integrated (120) can integrate one or more medium access control protocol data cells 122 to form single medium access control protocol data cell (A-MPDU) 124 of integrating, and each medium access control protocol data cell is separated by medium access control protocol data cell delimiter 126.Entity (PHY) header 128 that comprises an intrinsic training and signal (SIGNAL) field 130 and HT training and signal field 132 is added into and integrates medium access control protocol data cell 124 to form an entity protocol Data Unit (PPDU) 134.
The entity protocol Data Unit is integrated (140) can integrate one or more entity protocol Data Units 142, and each entity protocol Data Unit comprises an entity header 144 and a medium access control protocol data cell 146.Comprise the entity header 148 of an intrinsic training and signal field 150 and HT training and signal field 152, be added to form a single integral entity protocol Data Unit (A-PPDU) 154.
The entity protocol Data Unit burst (160) that also is known as high yield (HTP) burst transfer relates to by single high yield platform (STA) with single medium access transmission frame 162 sequences.Each frame 162 comprises an entity header 164, has an intrinsic training and signal field 166 and HT training and signal field 168, and a medium access control protocol data cell 170.Frame 162 can be transmitted as part integral entity protocol Data Unit, or tool attenuating frame border interval (RIFS) 172 comes amplified medium efficient.
Integration or burst scheme can be supported the scheduled integration frame that is sent to single collector (just single WLAN destination), the scheduled integration frame that is sent to multiple collector (many WLAN destination just), or both.SRA is used to call single collector and integrates, and MRA is used to call the multiple collector integration.For example, but because medium access control service data unit integrated scheme only comprises a media access control address of identification form WLAN receiver address, integrate so it is normally used for single collector.On the other hand, because each the medium access control protocol data cell in integration or the burst comprises the media access control address that can discern different wireless local area network network receiver address, so medium access control protocol data cell is integrated, the burst scheme of integration of entity protocol Data Unit and entity protocol Data Unit can be used to single collector integration or multiple collector and integrate.
Frame is integrated and the burst scheme has the benefit that increases WLAN system efficient and total output.The most of frame of shortcoming is integrated and the burst scheme is not supported/friendliness saving power/battery.Subject matter is quite long duration of integrating frame and burst.So do not provided in advance if the data of relevant what platform (what WLAN destination-address just) are contained in the knowledge of integrating in frame and the burst, then each platform in the WLAN must receive Ji Xie Code and all integrate frame or burst to check whether frame or burst comprise by with some data that is sent to platform surely.
The action that receives and separate this tediously long grouping information of Code consumes the big energy of receiver of this platform, it should not listen attentively to (receiving and separate Code) if also the specific integration frame of unexpected receiver or the prior knowledge of burst then can obviously be saved power/battery if this receptions platform has some signs.
By providing what platform to have to integrate the relevant prior knowledge of data in frame or the burst, all do not have the platform of integrating the data in frame or the burst all can be sunk into sleep by integrate frame or burst the duration (just do not listen attentively to or Bu Xie Code all divides into groups) save power.On the other hand, if some more eventful first information is provided, then has the platform of integrating the data in frame or the burst and can save power.This prior information is the relevant transfer of data time point of integrating the platform in frame or the burst.To be this platform use during integration frame that comprises its data or burst partly basic conception when prior that dot information wakes (listen attentively to and decipher) up and be sunk into sleep during the residue that does not comprise its data partly, reduces its power consumption by this.
In the prior art, has the proposal that some support power/battery is saved.As shown in Figure 2, the integration medium access control protocol data cell integrated scheme 200 of TgnSync motion proposes to use multiple collector integration descriptor (MRAD) to be used as the scheduled interior first medium access control protocol data cell (integrating medium access control protocol data cell) of integration frame that is sent to multiple collector.Entity protocol Data Unit 202 comprises an entity header 204 and and integrates medium access control protocol data cell 206.Entity header 204 comprises an intrinsic training and signal field 208 and HT training and signal field 210.Integrate medium access control protocol data cell 206 and comprise the plural medium access control protocol data cell 214 that a multiple collector is integrated descriptor medium access control protocol data cell 212 and respectively separated by medium access control protocol data cell delimiter 216.
Multiple collector is integrated descriptor medium access control protocol data cell 212 and is used to following mode.Do not have the platform of integrating the data in frame or the burst and will receive and separate Code till multiple collector is integrated 212 end of descriptor medium access control protocol data cell, and platform can learn that its receiver address is not contained in multiple collector and integrates in the descriptor, and it can be sunk into sleep (its receiver just deenergizes) till integrating frame end.Because TgnSync requires the scheduled medium access control protocol data cell that is sent to identical receiver address to be positioned in the integration medium access control protocol data cell by that neighbours each other, so have that the platform of integrating the data in the frame will receive and decoding data till it receives all its medium access control protocol data cells and detects different receivers address in next medium access control protocol data cell, it can be in being sunk into sleep (its receiver just deenergizes) on this aspect till the integration frame end.
Even providing, multiple collector integration descriptor mechanism reaches medium access control protocol data cell is integrated saving power in the example for the multiple collector on basis the method for integrating, but multiple collector is integrated descriptor mechanism and is applicable to the integration of single-rate multiple collector, and be not enough to be applicable to that many speed multiple collector integrates (wherein integrating medium access control protocol data cell is transmitted with different rates), be used for the entity protocol Data Unit and integrate, be not suitable for the burst of entity protocol Data Unit.
One motion illustrates many speed (or many MCS) multiple collector integration (MMRA), and its relevant many speed multiple collector is integrated and supported power-saving when being used.This motion comprises uses the many speed multiple collector with platform identifier (receiver address just) information and time point offset information to integrate descriptor (MMRAD), and it can be used to power-saving.Many speed multiple collector integration descriptor is defined in the medium access control part of frame, and the single-bit in the entity part of frame (in the bright HT-SIG of the being positioned field) is used to indicate the appearance that many speed multiple collector is integrated descriptor.
Many shortcomings are born in the prior art motion, integrate descriptor or the very big and inefficiency of many speed multiple collector integration descriptor length as multiple collector, and it is a variable length, and only can be simplified by using fixed length packets.Also because of this big field, power-saving information can't be embedded into and should be kept in the undersized physical layer.Because power-saving information is transmitted so that medium access control position is accurate, so it integrates descriptor by very not strong to be not all decodable speed transmission of all platforms because of multiple collector.It also is a medium access control medium access control protocol data cell, so if its loss or if platform can not Zheng Que Xie Code it, then can not save power.Dot information was not provided with efficient manner when another shortcoming was.The medium of motion most applications integration at present access control protocol data cell is integrated, and can't integrate with the integral entity protocol Data Unit, the burst of entity protocol Data Unit, and many speed multiple collector is integrated or and strongly is operated with oppositely interrogating affair efficient.
Summary of the invention
This method can be applied to the frame integrated scheme, frame burst scheme, and the frame that is not integrated (just as be transferred into the single collector person).The invention is not restricted to power and battery and save, also can be used to other purpose,, be used for packet scheduler design or enforcement, or be used for various radio resource manager functionality as providing the addressing metrizability via simplifying group addresing.

Embodiment
After this, " platform " (STA) noun is including but not limited to user's equipment, and wireless transmission/receive unit is fixed or moving user unit, and calling set maybe can operate in any other type component in the wireless environment.After this be called as " access point (AP) " person is including but not limited to the B node, base station, address control unit, or any other in the wireless environment connects Jie's device.
The present invention can be applied to various different technologies, comprises the integration frame, the nonconformity frame, and inversion scheme is integrated the multiple response device scheme of (MRMRA) as the multiple response multiple collector, and oppositely news are engaged in, and many wheels are inquired about the multiple response multiple collector and are integrated many polls (MMP).Therefore, the defined power-saving scope of the present invention can contain separately, be not integrated, or the frame of single collector integration, all are integrated frame or outburst type, and all schemes that have the multiple response device or use many polls.
The platform group addresing
The invention provides the method for efficient addressing platform group.Because the finite size header as the physical layer header needs many bit groups, so the present technical scheme of addressing WLAN platform is not effective to them.Basically, at present WLAN system and method can not the efficient addressing physical layers or even the platform at medium access control layer place.
But proposition group addresing platform of the present invention, and can be used to the new Efficiency Scheme of the WLAN header of finite size.This group addresing can be used by various usefulness enhancement function, as power-saving, and RRM, improvement service quality (QoS), and packet scheduling (packet scheduler design and enforcement).When enough hour of platform number, it also can be used to unique identification and interrogate affair destination (as receiving the WLAN platform) at last.In the WLAN, the platform that efficient addressing can be by organizing access point to serve (as by and these platforms of linking of access point) be different groups, each group can comprise the multistation platform and reach." power-saving group ", " platform group ", or " address group " noun can be used to call this group.
Though the WLAN platform passes through its media access control address usually by unique identification, imitating strong enhancing and power-saving also can not need bright whole media access control address or the part media access control address of deciding platform to be reached.In addition, " group address ", " group identifier ", " group's marking device " or " group's group number " can be used to promote power-saving.As Fig. 3 example, suppose that it is four groups that access point 300 may be organized six platforms (302-312) of serving.One possibility is that access point 300 is assigned platform #1 (302) and #6 (312) to group 1, and platform #2 (304) is to group 2, and (310 to group 3, and platform #3 (306) is to group 4 for platform #4 (308) and #5.Access point 300 also can be put into the multigroup group with a platform.Among Fig. 3, both are deployed on group 1 and group 3 platform #5 (310) and #6 (312).
In case access point 300 decision is assigned platforms to one or more groups, then it can use any message pattern to send this to be assigned group or group's signal to this platform.For example, as platform #6 (312) in case linked with access point 300 and access point has been determined to assign or classification platform #6 when being group's 1 part, but access point use and management frame, action action frame, control frame or Frame indicate platform #6 it have been assigned to group 1.This signaling can be directed in every way, as by introducing newer field in linking or linking in the frame again; Management or action action frame (as be used to intercept to confirm that (ACK) sets up, news affair stream is set up, or directly interlinkage agreement (DLP) creator) had both been deposited; Confirm that as confirming, intercept to confirm to require (BAR) and intercepting (BA), starter integrate control (IAC)/responsor and integrate control (RAC), modulation encoding scheme (MCS) requires and the modulation encoding scheme is feedback; And Frame.
Some class confirms that (back coupling) can be used, and platform can confirm that it correctly receives its new group and assigns by this.Group assigns and confirms that subsequently (via feedbacking or affirmation) can be transmitted message in any both having deposited in the WLAN frame or by defining new frame.Access point can be relied on oneself and will itself be classified as special group part, and no group part can comprise any group part of other platform or every group part.Access point also can be assigned it group and is bonded platform and communicate by letter.
Access point can belong to the default group (as fixed value) that all platforms all are careful (as by the group of all 0 and 1 identifications; Among Fig. 3, access point belongs to group 0.Be not access in as yet an assignment go into the platform of group can suppose its be predetermined to be institute might group partly (belonging to every group till it is assigned particular demographic) as platform.Simultaneously, direct link setup or directly in the specific train of thought of interlinkage agreement (DLS or DLP), access point can transmit its group identifier that should use when directly talking with another platform (just how the person should be other platform by assign into group) or the substituting default group that can be used at this purpose to platform.
Group's assignment is assigned again or signaling can be directed at access point or platform is considered as necessary any time point place, and is not limited to the moment as agreement or binding.Also can be used static the assignment, and operator or user are configurable or to organize this platform or access point be necessary group by this, and this information is imported this platform or access point.Simultaneously, can be designed to assign by dispatching algorithm, by this platform can use do not have or a little clearly communicate by letter/signaling relies on oneself itself assigned to go into a group.
Various dimensions group can be defined, and it can be interpreted as having the inferior group in the group.For example, platform can be assigned to group 1 and subgroup 2.The subgroup notion is useful on the differentiation of the multistation interstation that belongs to same group.For example, if group 1 comprises three platforms, and have four available subgroup in the group 1, then this three platform respectively can be placed into different subgroup, provides by this between the platform in the group and further distinguishes.Therefore, more general example is to assign one or more the value to platform, and each value is represented a group, the subgroup in the group, and the sub-subgroup in the subgroup.More general example is to have a N dimension group, its can pass through N repeated order unit (g1, g2 ..., gN) be identified, and platform will be assigned the N value, a value is used for each N dimension (group's combination just).
Group also can be defined by considering other characteristic.For example, whether a group can discern broadcasting news and be engaged in being contained in the frame and effectively comprise all platforms in the access point coverage area.If access point wants to transmit the integration frame of the news affair that comprises the affair of broadcasting news and belong to group 2, then it can use group 0 to indicate to have the scheduled broadcasting news that are sent to all platforms to be engaged in, and can use group 2 to indicate to have the news that are used for group's 2 at least one platforms and be engaged in.This notion is particularly useful in when integrating the interior data of frame by the ordering of news affair type; For example, broadcasting news are engaged in and/or multiple spot transmission news are engaged in is placed before single-point transmission news are engaged in integrating frame.It is that the scheduled broadcasting news that are sent to all platforms are engaged in that broadcasting group can be used to represent data type.
Similar notion can be applicable to multiple spot transmission news and is engaged in, and has to indicate the one or more groups that multiple spot transmission news are engaged in.It is while or arbitrary frame interior (just the simple group group presents broadcasting or multiple spot transmission) that comes across that signable broadcasting of one group and multiple spot transmission news are engaged in.Frame type information can be used to define this group.For example, a group can be used to the management of frame, action or control types.When in addition, the service quality relevant information can be used to define group.
Have and to be used to organize platform and/or difference to interrogate many possibility algorithms that the affair type is an available groups.One algorithm uses storage list pointer bit group (as inserting storage list at random), and this inlet that comprises the media access control address of this platform is placed wherein.Because access point may be kept the look-up table of the media access control address of its relevant platform, so access point can use the media access control address of platform wherein to be stored in the minimum influence bit of the list index that inserts at random in the storage list.The second algorithm application hash function is in the media access control address (and if the platform of expection and other characteristic of news affair) of platform.Algorithm is that each group (or its platform) is monitored (measurement) load (just interrogating the usefulness of make suring), and dynamically changes this group's assignment in the mode that produces approximate equal even load between all groups.The 4th algorithm selects the minimum group's (with news usefulness of make suring) that uses to be assigned to up-to-date relevant platform.Other algorithm comprises to be attempted cutting apart/load/use between all groups of balance, and other factor of consideration, have similar frame as encapsulation/grouping and integrate requirement, use similar data rate or power level, or have these interior platforms of same group of similar service quality or RRM requirement.
Transmit group's assignment information
As above-mentioned, management, action, control or Frame can be used to transmit is assigned group's signal to platform, the group of another platform or the group of access point.For example, starter is integrated control/responsor and is integrated control, RTS/CTS, and the modulation encoding scheme requires and feedbacks, intercepts to confirm that requirements/obstructs confirm, binding/again binding requirement and response frame, or CF poll or service quality poll can be used to this signaling purpose.This signaling can comprise group's assignment message, and it comprises signable this and is a flag of group's assignment message, and up-to-date value (being encoded as bitmap or other pattern) of being assigned group.Assignment message also can comprise the information of being assigned group's scope, for example should quilt assignment group whether can be applicable to this platform, access point or another platform (as direct interlinkage agreement time).
In case platform correctly receives group's assignment message, it is up-to-date by assignment group that it can confirm that it has correctly been received via group's acknowledge message of getting back to access point.Alternatively be that platform can non-request mode be regularly confirmed group, and it can transmit group at variant communication range and confirms or acknowledge message.
Assign platform again to different groups
If do not satisfy the group that is assigned at present, then platform also can require group to assign again.For example, platform is measured its battery position standard, and if its power outage (just when specific door is intersected), it can tell access point via the very low message of power supply, and it may require group to assign again.Platform can comprise its battery position standard clearly in this requirement.When receiving message, access point can determine to deny or accept the requirement of platform and can assign this platform to new group.Because management, action, control or Frame indicate the access point design or organize its group useful, so platform can be in agreement, set up or whether have the ability of using the power-saving group information to save power via this of access point indicated it during any signaling stage.
The power-saving group information
Be suggested and be used to realize power-saving, simplify or mensurable addressing, scheduling frame (scheduler enforcement), any radio resource management function, or the information of any other usefulness enhancement function is called as generically " power-saving group information ".The use of this information is not limited to power-saving, and also can be used to other purpose, implements as the data scheduler; Require (just may be integrated these frames together) with the class paraconformity, similar data rate, similar power, or the platform that divides into groups of the similar service quality requirement in the same group; And various radio resource management functions.Spendable some or all frames of WLAN can comprise frame header (entity or medium access control header), frame main body, or any frame (as RTS/CTS, starter is integrated control/responsor and integrated control, CF poll or service quality poll) that before had been transmitted.The power-saving group information can comprise one or more following frag infos.
Occur or validity flag (PVF)
Field (or bit) is taken as flag (being referred to herein as flag) and indicates at least one fragment of power-saving group information and whether come across (in the frame header) in the frame.For example, appearance or validity flag can be used to indicate whether have power-saving information in the frame.Every frame is comprised by hypothesis in the example of power-saving information, and this flag may be unnecessary.Flag can be used to implement variable-length entity or medium access control header field or header.
For example, whether the signable header of flag extension occurs, and wherein this header extends and comprises all or some power-saving information.Bit can be used in the entity header signal field (as HT-SIG field or signal-N field) and indicate the additional orthogonal frequency multitask symbol of one (or more) and be provided in the HT-SIG field, and should additional orthogonal frequency multitask symbol comprises the field that all or some power-saving information can be provided.In another variation, flag can be used to indicate in general (pressure) orthogonal frequency multitask symbol that is contained in signal field, and does not need the power-saving information field availability or the validity of extra orthogonal frequency multitask symbol.Whether the signable power-saving group information of appearance or another use of validity flag (as by using another bit) is effective.
(or not occurring) marking device (GPI) appears in group
Frame comprises can discern the scheduled platform group that is sent to of frame.(or not occurring) marking device appears in group can be applied to individual frames, integrates frame, burst transfer or frame sequence.For example, a pattern of Ming Ding or coding group appearance (or not occurring) marking device information is reached by using bitmap (or curtain cover).Return previously described four groups of examples, group occur (or not occurring) marking device field can be defined as comprising four bits (b1, b2, b3, b4), 2 value indicates the data whether frame comprises at least one platform that is assigned to group 2 by this.In order to illustrate, when access point transmits data to as single platform of group's 2 parts the time, access point can use bitmap 0100 to indicate the platform that belongs to group 2 to have and come across some data that is transmitted in the frame, and this frame there is no and comprises the data that belong to other three groups.
Alternatively be that group can be defined service regeulations codings (as 10) and indicate this frame and comprise the scheduled data that are sent to the platform that belongs to group 2.
Another example, when using, access point integrates frame (as integrating when the use service data unit, medium access control protocol data cell is integrated, the entity protocol Data Unit is integrated burst, many speed multiple collector is integrated, when or many polls) transmitting data to platform, 0110 bitmap values indicates the data that frame comprises at least one platform of at least one platform of group 2 and group 3, and this frame does not comprise the data of group 1 or group 4.Even should note this example assumes four group group, but group's group number that any group of group number all can be used and bitmap is held to be used by expansion.Moreover employed group's group number can be rendered as dynamic variable.(or not occurring) marking device appears in group can be contained in the frame header, the entity header, medium access control header, the entity header, medium access control header, multiple collector is integrated descriptor, the multiple response multiple collector is integrated many polls, or the signal field of any many poll frames (intrinsic signal is in the HT-SIG, or signal-N).
Dot information during group (GTI)
Multiple collector is integrated in the example, and dot information can be saved higher-wattage to these platforms that are integrated in the frame when group was provided.Because dot information still can be reached power-saving by using group (or not occurring) marking device to occur during group, so the platform of nonconformity frame part does not need them.
How dot information is used when group is described, considers that bitmap values 0110 is used to indicate to integrate frame and comprise at least one platform in the group 2 and the data of at least one platform in the group 3.Those neighbours of data that suppose given group in integrating frame, then can discern time that is transmitted that the data of group 2 begin or near, and also discern time that is transmitted that the data of group 2 begin or near time dot information can be provided.
Dot information can make group allow data be sunk into sleep (just not receiving or separate Code) till the time point that data first fragment of this group is transmitted during group, thereby reaches power-saving therebetween.Can be sunk into sleep because receive platform, so in case it receives its data and detects and integrate the receiver address modification in next fragment data in the frame, power-saving can be reached.
Dot information when group is provided is respectively organized the time started (as the time migration pattern) to be provided in the frame.This information be belong to time point that data first fragment of any platform in the group begins to be transmitted or near.Dot information when providing group for efficient, except bright fully fixed (coding) each group's time started (or shift time), all group bases duration (base period just) can be used, and the different fractional values of identification time started (as time migration) can be used to each group.For example, suppose that the basis duration is 16 time quantums, then group's time started can be mark 3/4 by using dibit to be encoded and communicating by letter, and it means group's time started (as group's time migration) and is arbitrary (3/4 * 16=) 12 time quantum that comes the self-reference time point.
Basis duration information can be derived from the field of both depositing in the WLAN frame header.For example: speed (RATE) and length (LENGTH) field in the entity header intrinsic signal field; HTLENGTH and modulation encoding scheme field in the HT-SIG (signal) of TgnSync frame header; Or interior length and the Config field of signal-N (signal) field of WWiSE frame header can be used to derive basis duration information.The basis continues to be same as from what physical layer information was derived deceives the duration (SD).Using this to deceive the duration (maybe can from its any variation of being derived) is used as the basis duration efficiency method of coding and time point (as skew) information can be provided.Alternative is that the duration/identifier field of medium access control header can be used to derive this basis duration information.
Use time dot information example of dot information when deceiving duration and group is shown among Fig. 4.When the signable platform of dot information should begin to listen attentively to medium during group, and among Fig. 4, and dot information is given 1/4 and deceives the duration spacing when being encoded group.Dot information coding when table 1 has illustrated in Fig. 4 employed group.Though it should be noted that table 1 dot information when deceiving that the duration, mode illustrated group, dot information when any kind frame duration all can be used to encode group.
Dot information coding example during table 1. group
Group's time point value of information When platform begins is listened attentively to
00 Deceive the duration when beginning
01 Deceive duration 1/4 place
10 Deceive duration 1/2 place
11 Deceive 3/4 o'clock duration
Newer field can be added into the entity or the medium access control header of WLAN frame, is clearly used as the bright fixed basis duration.The basis duration can corresponding frame the full duration or the part duration of frame.Burst of entity protocol Data Unit or entity protocol Data Unit are integrated in the example, except defining the basis duration is single entity protocol Data Unit (or frame) duration, and the basis duration also can be defined as the burst of entity protocol Data Unit (the basic duration of just containing multiframe) or integral entity protocol data unit frame.Similarly, many speed multiple collector is integrated, and oppositely news are engaged in, many polls, or in many speed multiple collector integrated scheme, the basis duration can be contained the frame sequence full duration that is exchanged.
Except the duration of basis, each group's fractional value must be by bright fixed.Fractional value is multiplied by the basis duration to obtain group's actual transmission time started (as the skew of group's delivery time).Suppose the fixed reference denominator, then only denominator value must be by Ming Ding and communication.For example, suppose four denominators, dot information when then dibit can be used to group is provided.
(or not occurring) marking device occurring with 0110 groups that indicate group 2 and 3 appearance once more is example, and one of dot information may mode be that every group has dibit during coding group, so group's time point information comprises eight bit (b1, b2, b3, b4, b5, b6, b7, b8), bit b1 and b2 value can provide the numerator value of group 1 (not occur because group's appearance (or not occurring) marking device indicates group 1 by this, so it may not need in this example), and b3 and b4 provide numerator value of group 2 or the like.For example, transmit and will begin to locate or near time migration information in order to obtain group 2, we must be multiplied by the basis duration ' b3b4 ' value and divided by four.When this frame comprises the data that are used for this platform (just when the group of platform comes across in the frame), time migration information roughly is interpreted as platform will listen attentively to frame place or near time.
Dot information can be contained in the frame header during group; The entity header; Medium access control header; Or the entity header, medium access control header, multiple collector are integrated descriptor, and the multiple response multiple collector is integrated the signal field of many polls or any many poll frames, and (intrinsic signal is in the HT-SIG, or signal-N).Dot information needn't be contained in and be same as the position that (or not occurring) marking device appears in group during group.For example, group (or not occurring) marking device occurs and can be contained in the entity header, and dot information can be contained in medium access control header (integrating descriptor or the multiple response multiple collector is integrated in many polls as multiple collector) during group.
Timely dot information (GPTI) appears in group
Even dot information and group appearance (or not occurring) marking device information is defined as two independent field during group, it also can be merged to reach together by using predetermined reflection coding timely dot information to occur defines two interior category informations of a field (timely dot information appears in group).Shown in Fig. 4 and table 2, has the method for various two frag infos of encoding together.
Timely dot information coding example appears in table 2. group
Timely dot information value appears in group When platform begins is listened attentively to
00 Deceive the duration when beginning
01 Deceive duration 1/4 place
10 Deceive duration 1/2 place
11 Deceive the duration when finishing
Value 01,10 and 11 have been arranged, and platform can be sunk into sleep till listening attentively to the medium time, saves power by this.Because platform will be in deceiving that the duration begins to listen attentively to when finishing and being sunk into sleep during transmitting in frame is all, so the signable group of 11 particular example does not occur.Timely dot information appears in group can be contained in the frame header, in entity header or the medium access control header.Timely dot information appears in group can be contained in the entity header, and medium access control header, multiple collector are integrated descriptor, and the multiple response multiple collector is integrated the signal field of many polls or any many poll frames, and (intrinsic signal is in the HT-SIG, or signal-N).
Access point color (APC), sub-district color, or access point coverage area color
Have in the multiple access dot system that uses the same frequency channel, the platform in given sub-district (access point coverage area just) can be listened attentively to and betide near another or the transmission of the frame in the adjacent cell.In order to capture preferable power-saving usefulness in this example, the WLAN frame can comprise access point identification, and it can be called as " the access point color " or " groups of access points " or " the sub-district color " or " cell identification ".The access point color differs and is decided to be the unique identification of access point.For example, if access point 1, access point 2 and access point 3 closer to each other and use same frequency channels, then by using dibit to discern the access point color, access point 1 can be assigned 11 colors, and access point 2 can be assigned 01 color, and access point 3 can be assigned 00 color.The access point color can be contained in the frame header, entity header, medium access control header, the entity header, medium access control header, multiple collector is integrated descriptor, the multiple response multiple collector is integrated the signal field of many polls or any many poll frames, and (intrinsic signal is in the HT-SIG, or signal-N).
The platform that is access in a little 1 service can comprise in the frame of diverse access point color in the frame header further information by Bu Xie Code and save power ( comprise 00,01 or 10 frames of being used as its access point color and save power by not listening attentively to Huo Xie Code as platform and access point 1 binding).The access point color can multiple access dot system position standard further be saved power, even but do not have it, also can use said method to save power.
Listen attentively to direction or indication (LDI)
Listen attentively to direction or indication and illustrate that what person must be read ， Xie Code or explanation.In some example, the WLAN platform of non-frame expection receiver (just its data are not to be contained in the frame) still must read Ji Xie Code frame with the acquisition customizing messages.For example, platform need upgrade its part and be stored the NAV duration value, and it needs the duration/identifying information in the medium access control header of Xie Code frame at least.Alternative is that the responsible entity header information of platform (as length and speed, modulation encoding scheme or Config field) upgrades its NAV duration value.
Even receiving platform is not the expection receiver of frame, the frame conveyer can use still that field in the header (as bit or a little bit) is bright to read and separate Code all or some medium access control header informations surely and whether need receive platform.Whether conveyer also can use the bright platform that receives surely of another field should be to be contained in intrinsic entity header (as the intrinsic signal field), high production (802.11n just) entity header, or the information in the medium access control header (as the duration/identification field of medium access control header) is that the basis is upgraded its part and is stored the NAV duration value.
Whether duration/identification field (or being roughly whole medium access control header) that some recessive criterion can be used to derive medium access control header need be read.One criterion is comparable use intrinsic physical signalling field deceive the duration and use high production entity HT-SIG that (or signal-N) field deceives the duration.If have the particular differences amount between the two, then this difference can be interpreted as further reading and separating the indication that is released into medium access control header.
Simultaneously, whether the field (as a bit) in the entity header can be used as clearly listens attentively to direction or indication and indicates platform and can be sunk into sleep immediately, or should not be sunk into sleep and keep listening attentively to up to Qi Xie Code first medium access control header (or the some fragments of medium access control information) and then be sunk into sleep.Relevant listen attentively to how dark this of frame clearly indicate can further be enlarged where provide/when (how incident/field or when) stop immediately listening attentively to: after ASAP such as the Xie Code medium access control header, decipher after the first medium access control protocol data cell, after the decoding multiple collector integration descriptor or the like.
News affair direction
Also can save power by knowing news affair direction.For example, if transmitting news, given platform is engaged in, then the scheduled access point that is sent to of signable data in the frame header to access point.Because platform can be sunk into sleep during other platform is sent to access point, so they can be by watching this attentively " news affair direction " (TD) field or bit use this information to save power.In the medium access control header, and more clearly in the frame control field of medium access control header, have " to the DS " that can be used to discern news affair direction and reach " from DS " field.This information also can be used to save power.In addition, newly interrogating the affair direction can be placed in the entity header of frame at identification news affair direction specific purpose.News affair direction field can be placed on signal field (intrinsic signal, HT-SIG, or the signal-N) of entity header.This simple scheme advantage does not need specific new signal to send to set up group's (group comprises access point and is used as receiver, and other group comprises all platforms and is used as receiver) for it.
Withdraw from and integrate and the burst scheme
It is not to make the specified scheme signal partly of the too many power of platform consumption to access point that platform can transmit its preference, as specific integration or burst scheme, saves the power of platform by this.For example, platform can use and not want to make the scheduled data that are sent to it to become integration frame frame (management, action, control or Frame) partly.If access point agrees this requirement and confirm to agree to be back to platform, then this platform can be when detecting frame and utilize specified scheme be saved power by being sunk into sleep.For example, when the detection frame is integrated (by using signal field, as the information in the HT-SIG field), platform can be sunk into sleep in integrating image duration.
Platform can use does not want to make the scheduled data that are sent to it to become the particular type integration, as the frame of multiple collector integrated part.In this example, platform can be sunk into sleep the image duration that comprises the multiple collector integration.Similarly, platform can require it not want to make scheduled medium access control protocol data cell or the entity protocol Data Unit data integrated part that is sent to it, but it is with meaning the service data unit integrated part.Field in the frame header (in signal field) can be used to indicate the accurate type of integrated scheme that frame comprises.In case platform detects when not supposing to listen attentively to frame, because frame does not comprise the data of platform, so platform can be sunk into sleep in frame duration.But whether the platform agreement it support or preference integration frame reception (destination or single destination at the most).Platform can move by through management, and control or Frame transmission information are the feature tabular, menu bar, or the preference tabular partly comes agreement.Platform can be before linking, after linking immediately, certain time or any this frame that transmits At All Other Times after a while after linking.
Message also can dynamically be produced, as by making platform monitor that its battery position is accurate and crossing over specific door and transmission is excluded from requiring to access point of the scheme of power hungry (as the specific integration scheme) more.Dump power amount in the also signable message of platform, and preference is excluded certainly or alternative being incorporated into.
Frame type indicators
The flag that also can not be taken as the transmission of identification extrinsic frame with the use of reservation bit in the intrinsic physical signalling field (L-SIG) is as the 802.11n frame.Because platform can be sunk into sleep between the frame transmission period of these extrinsics (as the transmission of 802.11n frame), so this field can be used to save the power that intrinsic device is newly implemented (newly sending).
The timer of being sunk into sleep
In order to prevent that platform from keeping the fast knot situation of being sunk into sleep segment length period because of error situation, when platform enters when being sunk into sleep pattern, timer mechanism implements in the platform place.If platform is sunk into sleep above scheduled time interval (configurable parameter), then because it is in the fast knot situation, so it will wake up when timer stops and begin to listen attentively to once more medium.
Power-saving group information position
Any power-saving group information (PSGI) fragment all can be contained in any kind WLAN frame and any part WLAN frame.The power-saving group information can be contained in the entity header (as signal field), medium access control header, frame main body or postamble portion.Some fragment of power-saving group information can be contained in ad-hoc location in the frame (in the entity header), and some other fragment of power-saving group information can be placed somewhere in the frame (in medium access control header).
At integrating as the entity protocol Data Unit or entity protocol Data Unit burst frame partly, the power-saving group information can involved integration frame or burst in the middle of, for example in the physical signalling of intermediate frame (header), medium incoming control signal (header), midamble, or delimiter.Simultaneously, at integrating as the multiple response multiple collector, oppositely news are engaged in, and many wheels are inquired about the multiple response multiple collector and integrated many polls, and some power-saving group information fragment can be contained in the WLAN frame and multiple collector is integrated descriptor or the multiple response multiple collector is integrated in many polls.Add some power-saving group informations that are suggested and in this scheme, can increase its efficient (for example via time point information efficiency coding) and its usefulness of potential improvement.
