The MCS grades of MAC layer subframe requirement in the embodiment of the present invention refer to the MCS grades that ensure that the MAC layer sub-frame transmission requirement.The transmission requirement of MAC layer subframe includes following any：The qos requirement of the MAC layer subframe, the number of retransmissions requirement of the MAC layer subframe or MAC layer subframe MCS requirements set in advance.The qos requirement of the MAC layer subframe is higher, then requires letter
Breath transmission rate is lower, and corresponding MCS lower grades；The number of retransmissions of the MAC layer subframe is more, then require information transmission rate is lower, and corresponding MCS lower grades.The MCS grades of other frame requirements are also similar with the definition of the MCS grades of MAC layer subframe requirement, in addition, the MAC layer subframe being accumulated in the present invention is properly termed as converging subframe, so the MCS grades of convergence subframe requirement are also similar with the definition of the MCS grades of MAC layer subframe requirement.
RB in the embodiment of the present invention refers to the time/frequency source block or Physical Resource Block for transmitting data.For example：RB can be 12 continuous carrier waves on frequency domain, be the resource block of a time slot in time domain.The corresponding MCS grades of RB refer to the MCS grades used during RB transmission.
The MAC layer convergence frame format that the embodiment of the present invention is defined
A kind of aggregated frames converged by two or more MAC layer subframe are defined in embodiments of the present invention.
Specifically, Fig. 2 is the MAC layer convergence frame format that the embodiment of the present invention is defined, as shown in Figure 2, the MAC layer subframe that will be aggregated is referred to as converging subframe, then aggregated frames include a convergence frame head and two or more convergence subframe, wherein, convergence frame head includes convergence digital section and skew list field.
Further, convergence frame head also includes reserved field, signature field and check field.Each field is described as follows：
Convergence digital section：Number for indicating convergence subframe, the scope of the number is 0 to 2M- 1, wherein, M is the bit number of convergence number subfield；
Reserved field：For making the convergence frame head in addition to list field is offset be defined length, for example：When the length of convergence frame head of the regulation in addition to list field is offset is 32 bit, reserved subfield will then ensure that it is 32 bits；
Signature field：The aggregated frames are recognized for receiving the website or AP of aggregated frames, that is, receiving the website or AP of aggregated frames can judge whether the aggregated frames are aggregated frames that the embodiment of the present invention is defined with signature field, for example：Provide that the frame is that the embodiment of the present invention is defined when the value of signature field is 1
MAC layer aggregated frames, when the value of signature field is 0, the frame is not the MAC layer aggregated frames that the embodiment of the present invention is defined；
Check field：For being verified to the convergence frame head in addition to list field is offset, for example, verification subfield is filled according to the CRC check to demarcation head, so as to improve the success rate and serious forgiveness of convergence preamble transmission；
Offset list field：For indicating convergence subframe to the offset of convergence frame start position；
Further, skew list field includes n skew subfield, wherein, n is converges the number of subframe, and skew subfield is corresponded with convergence subframe, for example：As shown in Fig. 2 the correspondence convergence subframe 1 of skew 1, the correspondence convergence subframe 2 of skew 2, by that analogy, skew n correspondence convergence subframes n.Skew subfield indicates offset of the corresponding convergence subframe of the skew subfield in aggregated frames, that is to say, that skew subfield indicates the corresponding convergence subframe of the skew subfield to the offset of convergence frame start position.The position of corresponding convergence subframe can be directly positioned by inquiring about skew subfield.
Alternatively, the length of n skew subfield is consistent, wherein, each skew subfield indicates the end position of corresponding convergence subframe.According to one convergence subframe end position can obtain with the convergence subframe end position close to convergence subframe starting position.For example, as shown in Fig. 2 skew 1 subfield indicate convergence subframe 1 end position, with convergence the end position of subframe 1 close to convergence subframe 2 starting position can also according to convergence subframe 1 end position acquisition.Further, skew i subfields correspondence convergence subframe i end position, skew i-1 subfield correspondence convergence subframes i-1 end position, it is possible thereby to obtain convergence subframe i original position and end position.As long as that is, two adjacent skew subfields are correct, it is possible to determine a convergence subframe, such as offseting subfield i-1 and skew subfield i being correct, corresponding convergence subframe i can be determined by just having, wherein, i is 2 any one integer for arriving n.In addition, the original position of convergence subframe 1 can be calculated according to convergence frame head.Further, according to convergence subframe i original position and end position, convergence subframe i length can also be obtained.
Alternatively, skew list field need not can be verified.For example, for adjacent skew
Field i-1 and skew subfield i, it may be determined that the convergence subframe i gone out.It is MAC layer subframe to converge subframe i, so its afterbody includes 32 crc fields, carries out CRC detections to judge to converge whether subframe i is a legal MAC layer subframe using the crc field.The end position of subframe is accurately positioned it is possible to further carry out blind check using the crc field.So, even if some skew subfields receive mistake in multiple skew subfields, as long as two neighboring skew subfield is correct, it is possible to determine corresponding legal convergence subframe.Therefore skew list field need not verify protection, so as to reduce the expense of aggregated frames, save system resource.
It is possible to further reduce error probability during skew list field transmission by using the relatively low corresponding rate of information throughput Transmission Convergence frame head of MCS grades, so as to improve the success rate and serious forgiveness of aggregated frames transmission.
Alternatively, skew subfield indicates the offset of following any skew granularity：The offset of modulation symbol, the offset of bit, the offset of byte, offset of microsecond etc..For example, the length of skew subfield is 16 bits, can represent 0~216The offset of individual skew granularity, when some corresponding decimal integer value of skew subfield for 20 and indicate be modulation symbol offset, then it represents that the starting location offset offset of 20 modulation symbols of the skew subfield corresponding convergence subframe relative to aggregated frames.
Further, each convergence subframe is a MAC layer subframe, and the MAC layer subframe can be MPDU or A-MSDU or other customized mac layer frames or MAC layer aggregated frames.For example, as shown in Fig. 2 convergence subframe includes delimiter field, data field and filling field, wherein, data field can be MPDU or A-MSDU.
Alternatively, when being converged to each convergence subframe, directly end to end it can be converged, without filling up redundant data between each convergence subframe.Convergence frame overhead can be so saved, system resource is saved.For example, the delimiter field and filling field that the convergence subframe that is, shown in Fig. 2 includes can be omitted, and directly converge MPDU or A-MSDU, convergence frame overhead is saved with this.
Further, the MCS grades of convergence subframe requirement can be different, that is to say, that will can require
The different convergence subframe of MCS grades converge in an aggregated frames.
In IEEE 802.11n/ac, existing A-MPDU aggregated frames need to scan for by unit length of 4 bytes, quickly to orient each subframe, therefore when transmitting terminal carries out the convergence of subframe, each convergence subframe needs to carry out the registration process of 4 bytes, to ensure that the length of each convergence subframe is the positive integer times of 4 byte lengths, so that receiving terminal can carry out 4 byte search.Relative to existing A-MPDU aggregated frames, the MAC layer aggregated frames that the embodiment of the present invention is defined, convergence subframe is determined as a result of based on skew list field, namely utilize two adjacent skew subfields, the original position and end position of corresponding convergence subframe can be determined, and then each convergence subframe is also without 4 byte-aligned processing of progress, it is possible to reduce fill up redundant data, convergence frame overhead is saved.In addition, after convergence frame head verification is correct, the speed of solution convergence can be improved directly quickly to determine convergence subframe according to skew list field.
The downlink processing process of the embodiment of the present invention
Fig. 3 is the AP sides downlink processing process schematic of the embodiment of the present invention, as shown in figure 3, AP sides downlink processing process includes：
Step 301：The more than two MAC layer subframes for being sent to same STA are pooled aggregated frames by AP；
There is N number of MAC layer subframe to be destined to same STA in AP MAC layer subframe queue, wherein, N is the positive integer more than or equal to 2.N number of MAC layer subframe is carried out pooling aggregated frames, wherein MAC layer subframe can be referred to as converging subframe in aggregated frames, it is alternatively possible to which according to the qos requirement of each convergence subframe, number of retransmissions requirement or MCS set in advance requirements, the MCS grades of subframe requirement can must be converged；
As shown in figure 4, alternatively, can from low to high be converged according to MCS grades to the multiple convergence subframes for being sent to same STA, that is, converge subframe 1 and raised successively to the MCS grades of convergence subframe N requirements.Especially, when the MCS grades of more than two convergence subframe requirements are identical, these
It is required that MCS grades identical convergence subframe order can be arbitrary.
Alternatively, the multiple convergence subframes for being sent to same STA can also be converged in any order.
Alternatively, the aggregated frames that step 301 convergence is obtained can be the MAC layer aggregated frames that the embodiment of the present invention is defined.Specifically, convergence frame head as shown in Figure 4 can be the convergence frame head for the MAC layer aggregated frames that the embodiment of the present invention is defined, and convergence digital section indicates the number of the convergence subframe of the aggregated frames, and skew list field indicates the offset of each convergence subframe.
Alternatively, the obtained aggregated frames of step 301 convergence can be the MAC layer aggregated frames defined in existing protocol or standard.For example, the MAC layer aggregated frames can be the A-MPDU aggregated frames defined in IEEE 802.11.The MCS grades for the convergence subframe requirement converged in the embodiment of the present invention can be different, certainly, and the MCS grades for the convergence subframe requirement converged in embodiments of the present invention can also be identical.
Step 302：AP sends resource allocation message to STA, wherein, resource allocation message includes the information for indicating more than two resource block RB, more than two resource block RB at least two different codings of correspondence and modulation strategy MCS grades；
Specifically, AP carries out resource block RB distribution according to the aggregated frames for being sent to STA, and the object information for indicating distribution is included by resource allocation message, and resource allocation message is sent to STA by AP.
Further, the MCS grades that AP can be required according to the length and convergence subframe of aggregated frames, obtain the RB numbers of each MCS grade needed.To consider that RB carries the mode of aggregated frames when calculating RB numbers, which is to be carried on aggregated frames on RB successively from the beginning to the end.That is, when some converges subframe whole carrieds, and some RB for carrying the convergence subframe is not when being all used, convergence subframe close to the convergence subframe afterbody will continue to be carried on the RB, by that analogy, until the RB is all carried using the new RB of complete reselection or the aggregated frames are all carried on RB.
Alternatively, when convergence subframe is converged from low to high according to MCS grades, the corresponding MCS grades of convergence frame head can be calculated according to the MCS grades of the convergence subframe requirement close to convergence frame head.
Alternatively, when convergence subframe is converged in any order, the corresponding MCS grades of convergence frame head can be calculated according to the lowest class in the MCS grades of all convergence subframes requirements.
Further, resource allocation message can be medium access protocol MAP message or signaling SIG (English：Signal) message.
Alternatively, AP is to STA transmitting medium access protocol MAP messages, wherein, MAP message includes two or more allocation unit, and two or more allocation unit indicates two or more resource block RB information, and different allocation units indicates the RB information of different MCS grades；
Fig. 5 is MAP message structure chart, as shown in figure 5, MAP message includes site identity field, length field and one or more allocation units.Further, allocation unit includes RB startings subfield, RB skew subfields and MCS subfields.Wherein, each field and each subfield are described as follows：
Site identity field is used for the website for indicating to distribute to RB；
Length field is used for the number for indicating allocation unit；
The original position for the corresponding RB of allocation unit that RB starting subfields are used for where indicating it；
RB skew number subfields are used for the number for indicating the RB since RB originates the RB that subfield is indicated；
MCS subfields are used for the corresponding MCS grades of RB for indicating the allocation unit where it.
Alternatively, AP sends signaling SIG message to STA, wherein, SIG message includes more than two SIG subfields, and more than two SIG subfields indicate two or more resource block RB information, and different SIG subfields indicate the RB information of different MCS grades；
Fig. 6 is SIG message structure figures, as shown in fig. 6, SIG message includes site identity field and more than two SIG subfields, alternatively, SIG message also includes reserved field.Further, SIG subfields include MCS fields and RB digital section.Wherein, each field and each subfield are described as follows：
Site identity field is used for the website for indicating to distribute to RB；
Reserved field is used to indicate other additional information；
MCS fields are used for the corresponding MCS grades of RB for indicating distribution；
The number for the RB that the SIG subfields that RB digital section is used for where indicating it are distributed.
Step 303：Aggregated frames are carried on two or more RB and are transmitted by AP；
Wherein, STA RB, two or more RB at least two different MCS grades of correspondence are distributed to according to step 302.As shown in Figure 4, convergence frame head and convergence subframe 1 are carried with the RB with the MCS ratings match of the convergence requirement of subframe 1, when some RB of carrying convergence subframe 1 has not been used, convergence subframe 2 is continued to be carried on the RB, until the RB is all used, then continue carrying convergence subframe 2 with the RB with the MCS ratings match of the convergence requirement of subframe 2.The like, whole load bearing process seeks to fully use each RB, and the MCS grades of convergence subframe requirement will match with carrying the corresponding MCS grades of RB of the convergence subframe.
Wherein, the MCS grades MCS grades corresponding with RB of convergence subframe requirement, which match, refers to, in all MCS grades for meeting convergence subframe requirement, grade highest MCS grades are the corresponding MCS grades of RB.At this moment, the corresponding MCS grades of RB and the MCS grades of convergence subframe requirement match.
Further, if a RB carrying two or more converges all or part of subframe, and when the MCS grades difference of subframe requirement is converged more than the two, the corresponding MCS grades of the RB MCS grade minimum with the MCS grade middle grades that subframe requirement is converged more than the two matches.
For example, there are the aggregated frames for being sent to website 1, it is that the convergence frame head and 3 length of 80 bits are the convergence subframe of 1000 bits including a length, 3 convergence subframes are respectively convergence subframe 1, convergence subframe 2 and convergence subframe 3 according to from convergence frame head to the order of convergence tail, the MCS grades for converging the requirement of subframe 1 are MCS1, the MCS grades for converging the requirement of subframe 2 are MCS2, and the MCS grades of the convergence requirement of subframe 3 are MCS3, and the wherein order of MCS grades from low to high is：
MCS1、MCS2、MCS3.Convergence frame head is calculated according to the MCS grades of the convergence requirement of subframe 1, that is, the MCS grades for converging frame head requirement are MCS1.Assuming that when a MCS grade can carry 100 for MCS1 RB, it is 1080 bits to converge frame head and convergence subframe total length, so at least needing the RB that 11 MCS grades are MCS1, there is a RB to carry 20 bits in this 11 RB, then for 20 bits of the close convergence subframe 1 for carrying convergence subframe 2；Assuming that when a MCS grade can carry 200 for MCS2 RB, remaining convergence subframe 2 at least needs have a RB to carry 20 bits in the RB that 5 MCS grades are MCS2, this 5 RB, then for 20 bits of the close convergence subframe 2 for carrying convergence subframe 3；Assuming that when a MCS grade can carry 300 for MCS3 RB, remaining convergence subframe 3 at least needs the RB that 4 MCS grades are MCS3.It follows that the aggregated frames need the RB that RB and 4 MCS grade that the RB that 11 MCS grades of distribution are MCS1,5 MCS grades are MCS2 is MCS3.Then by the allocation result, website 1 is sent to by MAP message, wherein, STA ID at least websites 1 in MAP message, 3 allocation units of Length Indication, allocation unit 1 indicates the RB that 11 MCS grades are MCS1, and allocation unit 2 indicates the RB that 5 MCS grades are MCS2, and allocation unit 3 indicates the RB that 4 MCS grades are MCS3.
Further, the MCS grades of convergence subframe requirement are determined according to service quality QoS, number of retransmissions or the MCS grades set in advance of convergence subframe.
Alternatively, when the MCS grades of each convergence subframe requirement are MCS grades set in advance, the corresponding MCS grades of RB are needed to match with MCS grades set in advance, that is to say, that the corresponding MCS grades of RB are determined according to MCS grades set in advance.If all or part of the one or more convergence subframes of RB carryings, the corresponding MCS grades of the RB preset the minimum MCS grades of MCS grade middle grades with the subframe of convergence more than the two and matched.
Alternatively, when the MCS grades of each convergence subframe requirement are determined according to QoS, the MCS grades that QoS grades highest convergence subframe is required in the two or more convergence subframe that the corresponding MCS of each RB is carried with it match.
Alternatively, when the MCS grades of each convergence subframe requirement are determined according to number of retransmissions, often
MCS grades of the convergence subframe requirement of number of retransmissions at most match in the two or more convergence subframe that the corresponding MCS of one RB are carried with it.
Aggregated frames are carried on the RB of different MCS grades and sent, namely pass through multi -rate transmission aggregated frames, so that transmission rate and the MCS ratings match of the convergence subframe of its carrying requirement, the RB of the different MCS grades for transmitting is determined according to the MCS grades of different convergence subframe requirements, so, RB can be more fully used, so as to improve system transmission capacity and system efficiency of transmission.
Further, when the RB of carrying convergence subframe N afterbodys has not been used, it can be carried on redundant data on the RB, for example, can be with zero padding.
Further, after aggregated frames are carried on RB, it is sent to STA；
