The rule divided in wlan system about resource block size are as follows: the smallest resource block includes 26 subcarriers.In addition to this, including 52 subcarriers, 106 subcarriers, 242 subcarriers, 484 subcarriers, the resource block of 996 subcarriers.Correspondingly, biggish resource block is considered as 2 times of the least resource block of 26 subcarriers, 4 times, 9 times, 19 times, 38 times.

Whole bandwidth is divided into multiple resource units (subband), is carried out data transmission using multiple resource units to multiple STA by a kind of possible data structure of 802.11ax as shown in Figure 3, AP.In order to allow STA Learn whether oneself is purpose STA, and, the physical layer parameter of resource block location and reception data where allowing purpose STA to obtain primary data, AP needs to carry out the instruction of resource scheduling information before transmitting the data.In general, indicating that multiple STA carry out the reception of data comprising the resource scheduling information of multi-user STA in HE-SIG-B.

Fig. 4 is a kind of possible structure of HE-SIG-B comprising public domain (common part) and one by one website domain (dedicated part).Wherein public domain includes that all purposes STA requires some public informations read; such as protection interval (the Guard Interval of data portion; GI); the location information of resource block or resource unit allocation; the OFDM symbol number etc. for the HE-LTF (High Efficient Long Training Field, efficient long training sequence) for needing to send；And in the information that website domain one by one contains each STA or one group of STA needs to read in the same resource block, it wherein include site identity (STA Identifier, STA ID), modulation and coding strategy (Modulation and Coding Scheme；Referred to as: MCS) it is used to indicate modulation and coding strategy, empty time stream number (Number of Space-Time Stream；Referred to as: NSTS) it is used to indicate the empty time stream number used, low density parity check code (Low Density Parity Check；Abbreviation LDPC) it is used to indicate whether using LDPC coding mode；Space-time block code (Space Time Block Coding；It referred to as: STBC) is whether to be used to refer to using STBC；Beam forming (Beamforming, BF) is used to indicate whether to use beam forming technique.In addition to this it is possible to include Cyclic Redundancy Code (Cyclic Redundancy Code；Referred to as: CRC) it is used to save CRC check bit；Tail bits (Tail) are used to store binary cyclic convolutional code (Binary Convolution Code；The tail portion of 6 bits referred to as: BCC).

Such as Fig. 4, resource block location information can also indicate respectively the position of its resource block other than it can be placed in public domain for each STA.That is, can only include resource block location information in public domain, or only in the position that website domain part includes resource block, alternatively, can public domain and website domain all include resource block the relevant information in position.Its specific indicating mode is herein with no restrictions.

Embodiment one

It is currently, there are the indicating mode there are many resource block location, the case where a kind of more efficient mode is that all possible combination is existed in a table, and each resource block of index of reference instruction distributes.In 802.11ax, the size of multiple resources block is defined at present, is divided into 26,52,106,242,484,996 etc. according to the number of subcarrier.Wherein 26 subcarriers correspond approximately to 2MHz, and 52 subcarriers correspond approximately to 4MHz, and 106 subcarriers correspond approximately to 10MHz, and 242 subcarriers correspond approximately to 20MHz, and 484 sons carry Wave corresponds approximately to 40MHz, and 996 subcarriers correspond approximately to 80MHz.But simultaneously non-fully correspond to, for example, when bandwidth is 80MHz, there can be the large resource block of 4 242 subcarriers, in addition to this, can also there is the small resource block of 26 subcarriers in middle section.

Fig. 5 is the combination for the possible OFDMA resource block of the total bandwidth of 20MHz, for 20MHz, the size of resource block may be 26,52,106 (due to being represented 106) using in 102, Fig. 3 by 102 before, one shares 25 kinds of situations, then corresponding 25 sequence index only need to carry ceil (log in common portion₂25)=5 bit can carry all possible situation of 20MHz, and wherein ceil expression rounds up.It is 40MHz for total bandwidth, the case where 80MHz, 160MHz, can equally enumerates all possible situation, list index be carried out, finally by all possible situation of several bit indications.Certainly, it is 40MHz for total bandwidth, the case where 80MHz, 160MHz, list index can also be carried out respectively to each 20MHz, be indicated respectively.

In addition, with reference to Fig. 6, when the position OFDMA is distributed, it is also possible to while considering that multiuser MIMO (Multiple-user MIMO, MU-MIMO) is transmitted, i.e., multi-user's distribution in some subband on further progress spatial flow.For example, when such as 106 or 242, can allow further to be transmitted using MU MIMO in the subband when resource block is sufficiently large.In addition, the case where there are also do not occupy all resource blocks, i.e., some resource blocks are empty, do not carry out the transmission of data.Both the above situation is considered simultaneously, has a kind of table index comprising the more comprehensive method of salary distribution, compared with former, more bits is needed to be indicated.The case where indicating the resource block of 1-8 wherein to meet transmission MU-MIMO can respectively correspond an index for the every case of 1 user to 8 users.

Certainly, it is similar with the scheme mentioned in Fig. 5, for scheme shown in fig. 6, it is 40MHz for total bandwidth, the case where 80MHz, 160MHz, all possible situation can equally be enumerated, list index is carried out, list index can also be carried out to each 20MHz in the total bandwidth respectively, indicated respectively.

In embodiment provided by the invention, the instruction of default resource allocation information is carried out by way of list index.Resource allocation information can be in such a way that reference table indexes, such as shown in Fig. 5, Fig. 6 of front, the index of default resource allocation information is used to indicate including one or more.

Aforementioned default resource allocation information includes:

1), the case where the division of default resource block.For example, the division of resource block as defined in AP and STA agreement or agreement is, if bandwidth is 40MHz, whole bandwidth to be divided into the resource block of two 242 subcarriers；If bandwidth is 80MHz, whole bandwidth is divided into four 242 subcarriers Resource block and 26 subcarrier resource block.Or, according to the dividing condition of the resource block of preamble transmission, determine the dividing condition of the resource block of current transmission, such as preamble uplink when 20MHz point be 9 26 subcarriers resource block, identical resource block division mode, is similarly the resource block of 9 26 subcarriers when then in downlink transfer using with preamble uplink.Alternatively,

2), the purpose STA (STA distributed on resource block) of default resource block.That is, participate in the STA of preamble transmission receive in the resource block according to prespecified mode/send data.For example, for taking part in the STA of preamble transmission, can according to transmitted in this transmission with preamble in identical resource block or the resource block of preamble transmission belonging to inscribed transmit/receive of resource block of 242 subcarriers send data.In addition to this, data can also be sent in inscribed transmit/receive of which resource block by beacon (Beacon) frame or which pre-specified STA of certain management frame before.Alternatively,

3), as a kind of special circumstances, the reply mode of default acknowledgement frame.How to be distributed including resource block, acknowledgement frame is sent on which resource block, and which STA to send acknowledgement frame by.1) and 2) wherein, 3) contain the content for needing to default instruction in, in addition to this, 3) in what mode can also reply the acknowledgement frame of what mac frame type, such as O-BA, M-BA, OFDMA M-BA and BA including the use of.

Specifically, the case where index in embodiment one not merely indicates the division of resource block, but the case where include the division of resource block and the information of the purpose STA of resource block.Specifically, including two kinds, the first is: for total bandwidth to be allocated, which is used for while indicating the division of resource block and whether the purpose STA of each resource block is the STA defaulted；Second is: the case where resource block divides uses certain known or other mode to be indicated, which is used to indicate whether the purpose STA distributed in each resource block is the STA defaulted.

A special case for the first is that the index is used to indicate default validation testing, i.e., what is carried in restriction resource block is the acknowledgement frame of certain MAC type.

In addition to this, it is sending except the instruction about default resource allocation information, can also first indicate to show unicast frame or multicast frame, further indicating the purpose STA of multicast frame.

Default resource allocation information can be a certain kind in above several default allocation modes；It can also be indicated respectively for each, establish index respectively.During specific implementation, each index and its corresponding resource allocation conditions and situations such as targeted sites can be stored respectively in transmitting terminal and perhaps receiving end or others modes use to know altogether for transmitting terminal and receiving end.

In one example, as Figure 11 a, multiple STA have carried out the transmission of uplink multi-users transmission frame according to the scheduling of trigger frame；When AP carries out the reply of downlink acknowledgement frame, resource block distribution instruction index is 26 The distribution of (be only for example and can be other value), the resource block will be allocated according to shown in Fig. 7, be divided into the resource block of two 242 subcarriers.Then the STA for transmitting upstream data in 242 Subcarrier ranges to preamble using the resource block of 242 subcarriers carries out the confirmation of M-BA frame.

Such as Figure 11 b, in another example, if resource block distribution instruction index is 27 (are only for example and can be other value), resource block distribution will be allocated according to the situation in Fig. 8 a, the distribution of resource block is identical as the resource block distribution of preamble transmitting uplink data, if the data that some subband of preamble is single STA are transmitted, O-BA is replied；If the data transmission that some subband of preamble is the MU MIMO of multiple STA, replys M-BA.

In another example, it is 28 (are only for example and can be other value) that resource block, which distributes and indicates to index, then such as Figure 10 a, defaulting website one by one to indicate to come in the middle included in the resource block of k-th resource instruction is M-BA frame.Resource block distribution instruction index is 29 (are only for example and can be other value), and such as Fig. 9, then the mode for defaulting reply carries out the mean allocation of resource block for the STA number for needing to reply acknowledgement frame, then replys O-BA in each resource block.

For this implementation method, it is equally applicable to the instruction that uplink scheduling information resource block distributes in trigger frame, the purpose STA that acknowledgement frame immediately is asked in indicating downlink frame distributes the transmission that uplink acknowledgement frame is carried out on corresponding resource block according to the resource block of default.

Two kinds of situations shown in Figure 11 a, Figure 11 b are the method that default resource allocation information instruction is carried out for whole bandwidth, that is, the value indexed be used to indicate and meanwhile contain resource block division and purpose STA whether the default resource allocation information for being default STA.

In addition, as shown in fig. 11c, can be indicated respectively for each resource block.For example, just for the larger situation of resource block (greater than threshold value 106 or the resource block of 242 subcarriers) ability multicast data transmission, wherein distribute an index value for the every case for the MU MIMO number of users that the resource block is propagated.Wherein Figure 11 c show simplified expression, what the 1st row was effectively equivalent to concentrate illustrates 81 rows, corresponding 81 index values, respectively N1-N81, the resource block that wherein left and right two 106 (1~9) respectively indicates that the size of the position is 106 distributes to the user of any one quantity in 1~8, the purpose STA that 9th kind of situation is used to indicate the resource block is the STA of default, alternatively, being used to indicate transmission group broadcasting frame on the resource block.It can see from Figure 11 c, on the one hand index value indicates the distribution condition of resource block: 106 resource block, 26 resource block, 106 resource block, whether the purpose STA on the other hand indicating some particular resource block is the STA defaulted.

Figure 11 d gives a kind of identification method of expansion of Figure 11 c, wherein index N90 indicates that 20MHz is divided into 106,26,52,52 four resource blocks, the purpose for the resource block that first size is 106 in order STA is the STA of default, and index N99 expression 20MHz is by the resource block as 1 complete 242 subcarrier, and its purpose STA is the STA of default.

MU MIMO number of users is that any one value in 1~8 can also include in the present embodiment another index value, it is equivalent to, such as the 9th kind of situation of larger resource block, the purpose STA for being used to indicate the resource block is the STA of default, for example, preamble sends the website of uplink information.

In addition, as shown in fig. 11c, for each resource block, also can indicate that resource block propagation is multicast frame.It about the purpose STA of multicast frame, can allow to transmit a multicast MAC frames by limiting only, and participate in the STA of unicast reception without receiving multicast frame to complete.When STA learns that oneself is not engaged in unicast transmission in this way, the reading of multicast frame can be carried out, identified by reading the STA ID of MAC Address or mac frame body oneself whether be the multicast purpose STA.It can also be by carrying special multicast ID, to indicate the being multicast frame for thering is the fixed multicast frame being grouped either temporarily to be grouped.Or, biggish resource block can be directed to, 10th kind of situation, the mac frame that corresponding index value is used to indicate resource block transmission is the mac frame (being temporarily grouped) for participating in the STA of preamble uplink and just needing to read, correspondingly, being used to indicate the multicast transmission of fixed grouping for the corresponding index value of the 9th kind of situation.

In the above-mentioned multicast transmission being temporarily grouped, multiple purpose STA (the whole STA being not necessarily in cell) uncommon multicast mac address (non-broadcasting MAC Address) identifies this group of STA.For example, the STA for the multiple participation uplink multi-users transmission arbitrarily dispatched replys these STA according to M-BA mode, then often there is no common multicast mac address by multiple purpose STA of M-BA.In the multicast transmission of fixed grouping, the common multicast mac address for having MAC layer or more to distribute can be used for identifying the purpose STA of the multicast transmission of fixed grouping.

In embodiment one, carried out by the value of the index of more default resource allocation informations the instruction of unicast/multicast packet and or default validation testing instruction.It, can also be for the instruction of each STA or the scheduling of resource parameter for carrying out physical layer respectively for the STA group (MU MIMO user group or multicast transmission user group) in each resource block after the instruction for having carried out common portion.Due in common portion it has been found that the mac frame of each resource block transmission is unicast/multicast, if unicast data, it is single STA or MU MIMO user group, so website domain can be specifically designed the mode of resource instruction for the difference of each transmitted within resource blocks mode one by one.It for example, can be without the instruction of the STA ID of the website distributed on its resource block for the resource block of default resource allocation information instruction.For multicast transmission, due to the received robustness of edge customer to be guaranteed, lower MCS is often used And individual traffic, therefore the transmission of multicast packet can be carried out using default resource allocation information, without indicating relevant physical layer parameter, such as MCS, NSTS, LDPC, STBC, BF etc..Therefore a kind of possible mode is the multicast packet for default transport, uses default resource allocation information completely without carrying out the instruction in website domain one by one.If the default resource allocation information indicated is that subsequent all resource blocks are all made of default resource allocation information, the instruction of public domain can be only carried out without the instruction in website domain one by one.

For the side STA, when STA reads resource distribution instruction, the index of the resource distribution instruction of reading is a kind of default resource allocation information, and oneself takes part in the transmission of preamble, then reading/transmission of resource block is carried out according to default resource allocation information；If being not engaged in the transmission of preamble, reading/transmission is not continued.

About default validation testing

One special case of the default resource allocation information mentioned in aforementioned embodiments is default validation testing.There are many default validation testings, each embodiment to it with no restrictions.

For example, a kind of acknowledgement frame of default replys mode 1, the reply mode for the default being illustrated in fig. 7 shown below.The STA of uplink is carried out for (242 subcarriers provide subband) in the 20MHz of place, AP is aligned reply in corresponding subband in the way of M-BA.And for the M-BA on different 20MHz, the transmission of M-BA is carried out by way of OFDMA.

In another example a kind of acknowledgement frame of default replys mode 2, it is resource allocation OFDMA BA (O-BA) transmission identical with preamble resource block.In addition, can reply M-BA on corresponding resource block if some resource block is MU-MIMO transmission or continue the progress O-BA transmission of the mean allocation resource block, as shown in Figure 9.

In another example a kind of acknowledgement frame of default replys mode 3, it is that the O-BA of mean allocation whole bandwidth replys mode.In order to balance the expense that each subband replys acknowledgement frame, whole bandwidth is divided equally according to the number of STA, carries out the reply of O-BA, as shown in Figure 9.

In another example, a kind of acknowledgement frame reply mode 4 of default, what it is for (Dedicated part) k-th of website domain one by one instruction biography is the multicast frame defaulted, and purpose STA is the STA that preamble takes part in UL MU transmission, other resource blocks are continued to provide, can transmit unicast frame or have the fixed multicast frames being grouped by further part.Preferably, this situation is suitable for the case where common portion and one by one website part combination coding.As shown in Figure 10 a, that default first instruction biography is the multicast frame M-BA of default, and the position of resource block can indicate, can also default.

It is to contain the default resource allocation information of resource block division, while containing the purpose STA in each resource block as default STA that the acknowledgement frame of above several defaults, which replys mode,.It certainly, in other implementations, can also only include the division of resource block, for example the division of instruction resource block is according to the division methods of above 4 kinds of modes, but the purpose STA of each resource block is individually indicated again；The division of resource block can also be first carried out, then whether indicative purpose STA defaults STA in each resource block.

Purpose STA (STA for participating in preamble transmission) about default resource block

The purpose STA for being previously noted default (default) resource block can be the STA for participating in preamble transmission, alternatively, the STA appointed in advance based on beacon frame and management frame.

In addition to descending multi-user transmits, multi-user's uplink is also introduced in 802.11ax, as shown in figure 12.AP sends trigger frame, which includes the resource scheduling information of multi-user's uplink for triggering multi-user transmission.After multiple STA receive trigger frame, according to the resource scheduling information in trigger frame, uplink frame almost is sent within the same time.The uplink frame that AP receives multi-user is multiple STA while sending multi-user's acknowledgement frame later.

Specifically, AP sends trigger frame, STA is needed to transmit uplink frame immediately after X frame pitch (X Inter-frame Space), and setting check is regular (Acknowledge Policy), if setting confirmation rule to feed back immediately, it is required that AP responds immediately to acknowledgement frame after being properly received data XIFS.For acknowledgement frame, " STA for taking part in preamble transmission " takes part in the STA of uplink frame transmission.Which in addition to this, need subchannel to receive the case where data depend on the resource allocation of default in for taking part in the STA of preamble transmission.

If AP sends descending multi-user frame to multiple STA, and setting check rule is to feed back immediately, then STA needs to respond immediately to acknowledgement frame after being properly received data XIFS.And AP can send trigger frame while sending downlink data, transmit the scheduling information for triggering acknowledgement frame, how instruction STA replys acknowledgement frame.It is to say the purpose STA that the downlink frame responded immediately to is asked in current downlink transmission, as shown in fig. lob then for " STA for taking part in preamble transmission " signified in the scheduling information in trigger frame.

If the AP/STA for having demanded acknowledgement frame does not receive/is properly received corresponding acknowledgement frame within one section of set time, then it is assumed that data are not properly received, or without solution to acknowledgement frame, then no longer assert oneself to be the STA for taking part in preamble transmission.

Embodiment two

It is indicated using the resource that special STA ID is defaulted

With reference to Figure 13, on the basis of the resource allocation information for shown in Fig. 4, in addition to the instruction (concrete mode is without limitation) of resource block location information, special STA ID is used to indicate that one or more purpose STA of the mac frame in some resource block participate in the STA of uplink for preamble.STA without participating in preamble uplink is then not necessarily to read the resource block.Wherein special STA ID can be the full 0 STA ID that perhaps complete 1 STA ID or AP and the STA of participation preamble transmission are appointed in advance.

STA reads STA ID, if STA ID is special STA ID, and the STA has participated in the uplink on preamble corresponding resource block, then reads the mac frame in the resource block；If the STA is not engaged in the uplink on preamble corresponding resource block, without reading the resource block.Wherein corresponding resource block for uplink resource block identical with the resource block or can belong to identical 20MHz (resource block of 242 subcarriers).

In addition it is also possible to go to indicate that the mac frame in this resource block is multicast MAC frames or unicast mac frame using special STA ID.

Certainly, further, with reference to Figure 14, two kinds of special STA ID can be reserved, when STA reads special STA ID 1, then it is assumed that be that the STA of the uplink for taking part in preamble corresponding resource block just needs to read；And special STA ID 2 is read, then it is assumed that the frame is the multicast frame of a fixed grouping, and the reading of selectivity is carried out according to certain rules., according to whether there is the unicast frame for issuing oneself, decide whether to be read out if regulation takes part in the STA of unicast frame without reading multicast frame if not two kinds of special STA ID.If STA supports to receive while unicast data and multicast packet, can be read out jointly.

It should be added that, for MAC (Media Access Control, media access control) frame transmission mode, there are unicast transmission (unicast), multicast transmission (multicast) and broadcast transmission (broadcast), wherein multicast transmission and broadcast transmission are referred to as multicast transmission (Groupcast) again.Unicast refers to package in the transmission of computer network, and destination address is a kind of transmission mode of simple target.It is that network today is most widely used, and commonly used network protocol or service mostly use greatly unicast transmission, such as all agreements based on TCP.In addition to unicast transmission mode, there are also broadcast and multicasts.The difference of they and unicast is that the destination address of broadcast is all targets in network, and the destination address of multicast is one group of target, and the member that the group is added is the destination of package.Here the number transmitted with single user above According to not identical with the data of multi-user transmission.Carrying out transmission of video/lecture contents transmission by multicast is a kind of important application scenarios in 802.11ax, will be widely applied in sports buildings, lecture theater.

Embodiment three

The instruction of default resource allocation information is carried out using special multicast ID

With reference to Figure 15, on the basis of the resource allocation information for shown in Fig. 4, in addition to the instruction (concrete mode is without limitation) of resource block location information, it further include unicast or the instruction of multicast, and, for multicast, the not common multicast frame for enjoying common multicast mac address of the multicast is indicated using special multicast ID, the STA defaulted is needed to remove the multicast frame read.

Wherein, unicast and the instruction of multicast packet can be indicated using the index using resource block location information mentioned in embodiment one, or other schemes are indicated that the present invention program is with no restriction.The scheme of others instruction unicasts and multicast by 1 bit for example, express or special STA ID implies mac frame on some resource block for multicast/broadcast mac frame (multicast) or unicast mac frame.Which if the mac frame for passing through 1 bit indication some resource block is multicast/broadcast mac frame, further can also indicate to be multicast group by multicast ID.

Wherein multicast ID can be mapped by way of hand shaking with multicast mac address by STA with AP.

Correspondingly, STA can be by reading the information received, and the mac frame for confirming that certain resource blocks are propagated is multicast MAC frames or unicast mac frame in receiving side.STA is distinguished after the mac frame in certain resource block is multicast frames, reads multicast ID, discovery multicast ID is special multicast ID, and the STA has participated in the uplink on preamble corresponding resource block, then according to default resource allocation information receiving multicast data, alternatively, reading the mac frame in the resource block；If the STA is not engaged in the uplink on preamble corresponding resource block, without reading the resource block.

For embodiment two and three, it may be noted that, STA ID or multicast ID can also implicitly be carried by way of scrambling or exclusive or, receiving end is by carrying out descrambling or anteiso- using special ID or identifying whether AP implicitly carries special ID, for such method still in the range of the present invention program considers.

Example IV

The instruction of default resource allocation information is carried out using single user packet configuration

There are three types of different packet configurations in 802.11ax, and for single user packet configuration, it is only necessary to the resource instruction for carrying out single STA there is no need to transmit HE-SIG-B, saves the expense of HE-SIG-B.Therefore example IV indicates that the packet configuration is single user packet configuration first, and wherein indicating mode can also be carried, the present invention program is with no restriction by showing instruction in HE-SIG-A by the way that the part L-SIG+RL-SIG is implicit.Then, the bandwidth that the packet configuration is indicated by special STA ID or special multicast ID is the resource block distribution carried out according to default resource allocation information, and the purpose STA of the mac frame in all resource blocks is default STA, that is, has participated in the STA of preamble uplink.Special multicast ID is the ID special when confirming that the address is multicast ID, such as full 0 or complete 1 or AP and STA pre-specified ID.

For this kind of mode, the physical layer parameter that can use single website carries out unified instruction to the mac frame in multiple resource blocks, wherein physical layer parameter, may include MCS, NSTS, LDPC or STBC etc. as shown in figure 16；Also the physical layer parameter of default can be directly used and use 1 spatial flow without instruction, such as fixed fix using MCS0, NSTS of MCS, LDPC fixation is set as 0, i.e., by the way of BCC, STBC fixation is set as 0, i.e., not by the way of STBC.

STA reads the frame that the frame is SU, and STA ID/ multicast ID is special STA ID/ multicast ID, and the STA has participated in the uplink of preamble, then the mac frame in the resource block is read according to default resource allocation information；If the STA is not engaged in the uplink of preamble, without reading the resource block.Read the reading of the physical layer parameter of SU or the physical layer parameter progress mac frame according to default in HE-SIG-A.

Embodiment five

Default resource allocation information is carried out using information bit expresses instruction

The instruction of default resource allocation information is directly carried out using information bit by the bit implicitly carried in L-SIG and RL-SIG or in HE-SIG-A or HE-SIG-B.The instruction of 1 bit can be directly carried out for whole bandwidth, instruction uses certain default resource allocation information；A variety of default resource allocation informations can also be indicated respectively.In addition it is also possible to be utilized respectively 1 bit on the basis of the resource allocation information for shown in Fig. 4 for each resource block in addition to the instruction (concrete mode is without limitation) of resource block location information and indicated.It for example, is certain default resource allocation information by 1 bit indication validation testing, i.e., resource block is according to certain default resource allocation information Distribution, and purpose STA is the STA for taking part in preamble uplink.

For the side STA, STA reads the default resource allocation information bit indication in L-SIG and RL-SIG or HE-SIG-A or HE-SIG-B, if the default resource allocation information of indicating bit is read, and the STA has participated in the uplink of preamble, then the mac frame in the resource block is read according to default resource allocation information；If the STA is not engaged in corresponding uplink, without reading the resource block.

Embodiment six

The instruction of default resource allocation information is carried out by not transmitting STA ID

AP is not transmitting website domain one by one or carrying out in such a way that website domain one by one does not carry STA ID the instruction of default resource allocation information.And for the side STA, can extrapolate whether website domain part carries STA ID by comparing the symbolic number of HE-SIG-B whether comprising website domain one by one or one by one, to know whether to have carried out the resource instruction of default resource allocation information.

The symbolic number instruction of HE-SIG-B can be carried in HE-SIG-A.And in HE-SIG-B in general OFDM symbol number occupied by common portion is fixed.It can indicate that the part HE-SIG-B does not only include website part one by one comprising common portion by symbolic number, i.e. the symbolic number of the HE-SIG-B indicated in HE-SIG-A is equal to the symbolic number of common portion；Further, it is also possible to carry out the calculating of HE-SIG-B symbolic number, by the information of common portion to indicate that website field does not include STA ID one by one.For example, if:

, then illustrate one by one website domain do not include STA ID, do not include STA ID by way of come the purpose STA of the mac frame of implicit indication subsequent transmission be default STA, that is, take part in the STA of preamble uplink.

Other inventive embodiments

Furthermore, for some STA/MU MIMO user group/multicast user groups instruction combined coding of HE-SIG-B common portion and STA indicating section one by one, and the case where being scrambled using identification information, it can be by carrying bit in L-SIG and RL-SIG or HE-SIGA, there are multicast transmissions for designation date part, and the sequence of the resource instruction of multicast transmission can be the position (for example, it is assumed that being forever first of the instruction of website domain one by one) of default or further indicate that multicast transmission refers to by information bit The sequence (being designated as k-th) shown.When STA learn the instruction of all domains of website one by one which for multicast transmission when, then can use multicast ID or special multicast ID go to descramble, simplify the reception process of STA.When STA learns that the mac frame transmitted on some position is multicast frame, the purpose STA of multicast frame can be further further discriminated between using method described in embodiment one.

For such situation, the multicast information bit indication that STA is read in L-SIG and RL-SIG or HE-SIG-A is descrambled in the position of default or indicated position using special ID if there are muticast data transmissions for designation date part.
