In the method given in Table 2, the number of streams of three users other than one user whose number of streams reaches the allocation threshold is represented by 6 bits (bl3-bl8), wherein the number of streams of each user is represented by 2 bits, for example Bl3, bl4 represents the number of streams of the first user (ie, the user with the lowest sequence number) other than one user whose flow number reaches the allocated threshold; assuming bl3, bl4 is 00, 01, 10, 11 respectively indicating that the number of streams of the user is 0, 1, 2, 3, and bl5, bl6 also represent the number of streams of a user according to the above rules. Then, the principle that the total number of user flows in the user set is not greater than the total allocation threshold is set, and the consecutive 4 bits (bl3-bl6) are set to the indication information that the number of users reaching the flow number allocation threshold is 2. 1111 indicates that the remaining 2 bits (bl7 and bl8) are set to the second user sequence number indication information that the number of streams reaches the distribution threshold. In this embodiment, the second user sequence indicator information is the second user sequence number.

In practice, the indication information that the number of users having reached the flow number allocation threshold is 2 may have other implementation manners. The consecutive 4 bits (bl3-bl6) are set to 1111 to indicate that the number of users reaching the stream number allocation threshold is 2, because bl3-bl6 indicates the number of streams of two STAs respectively according to the method shown in Table 2, 1111 is The bit sequence value that does not appear: 1111 indicates that the number of streams of both STAs is 3, and there is already one STA stream number of 4, then the total stream number exceeds the specified maximum value of 8. In practice, the bl3-bl6 indicating that the number of users reaching the flow number allocation threshold is 2 may be set to any bit sequence value that satisfies a specific condition, which is: respectively, indicating two STAs according to the method shown in Table 2. The bit sequence value does not appear when the number of streams is reached. E.g, In order to indicate that the number of users reaching the flow number distribution threshold is 2, it is also possible to specify that bl3-bl6 is set to 1110 or 1011. In addition, in order to indicate that the number of users reaching the flow number allocation threshold is 2, it is not necessary to use the 4 bits of bl3-M6, and any one of the two STA streams may not be indicated according to the method shown in Table 2. The bit sequence that appears can be, for example, bl3-bl5 of 111, or bl3, bl5, and bl6 of 111. In particular, in order to indicate that the number of users reaching the flow number distribution threshold is 2, a plurality of bit sequence values may be used, for example, bl3-bl6 is set to 1110, 1011 and 1111. In summary, the method in this embodiment is that, by using one or more bit sequence values satisfying a specific condition of the bit sequence, the number of users that reach the flow number allocation threshold is 2, and the specific condition is: determining that there is one arrival flow. Under the condition of a user who allocates a wide value, the bit sequence does not appear in the bit sequence when indicating the number of STA streams.

When the flag is 10, the number of streams is The number of users reaching the distribution threshold is 1. When the flag is 10, the number of users whose number of streams reaches the distribution threshold is 2; as shown in Table 5, when blO and bl l are 10, the number of streams arrives at the distribution. The user number indication information of the wide value is the user serial number, and each user serial number is represented by 2 bits, for example, the first user serial number is represented by bl2 and bl3, the second user serial number is represented by bl4 and bl5, and the remaining 4 digits in the flow number allocation information ( Bl6-bl9) is used to indicate the number of streams of the remaining 2 users in the user set.

As shown in FIG. 13 , the method for indicating the number of user flows provided by the embodiment of the present invention may include: Step 1301: Determine, according to the number of flows allocated to users in the user set, the number of users whose number of flows in the user set is non-zero, where The user collection includes 4 users;

Step 1302: Send the flow number allocation information to the communication peer according to the number of users whose number of flows is non-zero, wherein if the number of users whose number of streams is non-zero is less than 4, the flow number allocation information includes the first indication identifier and the flow number is not The number of streams corresponding to the zero user, the first indication identifier is used to indicate that the number of streams is non-zero. For example, as shown in Table 11, the stream number allocation information may be represented by 10 bits (bl0-bl9). Wherein, the first indicator is represented by a bitmap of 4 bits (bl0-bl3), and each bit of the bitma corresponds to one user. In this embodiment, the bit in the bitmap corresponding to the user whose stream number is non-zero is used. The method set to 1 sets the first indication identifier; if the number of users whose number of streams is non-zero is less than 4, the remaining 6 bits (bl4-bl9) are used to represent the number of streams corresponding to the user whose number of streams is non-zero, The number of streams (1-4) per user is represented by 2 bits. The number of users whose non-zero number of streams is less than 4 determines that the number of 1s in the first indicator is less than 4. At the same time, the number of 1s in the first indication flag must be greater than 1, because at least one user stream number is non-zero. However, in the case of the multi-user MIMO, the number of user streams must be non-zero, so that the number of 1s in the first indication identifier must be greater than 2. Note that if the number of users whose number of streams is non-zero is 2, then the number of streams corresponding to the third stream number represented by bl8 and bl9 is not meaningful. In practice, bl 8 and bl9 can also be specified in this case. Set to a fixed value, such as 00.

If the number of users whose number of non-zero flows is 4, and the number of flows corresponding to the non-zero number of users is less than 3 or there are two users whose flow number is 3, the flow number allocation information includes the first indication identifier. The second indication identifier and the number of flows corresponding to the non-zero user number of the flow number, and the second indication identifier is used to indicate that the number of flows corresponding to the user whose flow number is non-zero is less than 3 or has two users whose flow number is 3.

Specifically, for example, as shown in Table 12, the stream number allocation information can be expressed by 10 bits (bl0 - bl9 ). Wherein, the first indicator is represented by a bitmap of 4 bits (bl0-bl3), and each bit of the bitma corresponds to one user. In this embodiment, the bit in the bitmap corresponding to the user whose stream number is non-zero is used. The method set to 1 sets the first indication identifier; 设置 sets the second indication identifier with 2 bits (bl4 and bl 5 ). In this embodiment, when bl4bl5=00, the second indication identifier is used to indicate that the number of streams is non-zero. The number of streams corresponding to the user is less than 3. When bl4bl 5=ll, the second indicator is used to indicate that there are 2 users with a stream number of 3. When bl4bl5=00, the remaining 4 bits (bl6-bl9) are used. The number of streams corresponding to the user whose number of streams is non-zero, the number of streams per user (1 or 2) is represented by 1 bit; when bl4bl 5=ll, the remaining 4 bits (bl6-bl9) are used to represent the number of streams 3 The serial number is used to indicate the user serial number by using the bitmap method. For example, when bl6-bl9=0101, the number of streams of the second and fourth users is 3, of course, in actual use, The two users with the number of streams 3 are assigned 2 ratios respectively. Specifically, the two bits are used to identify the user serial number.

When the flow number allocation information is sent by using the second method, first, the method for indicating the number of user flows provided by this embodiment considers that the flow number allocation information is transmitted in the form shown in Table 26, and can be sent through the form of Table 26. 27+3=30 kinds of flow number distribution. Among them, 27 kinds of normal flow number distribution, including: (1,1,1,1), (1,1,1,2), (1,1,2,1), (1,1,2,2 ), (1, 2,1,1),

(1.2.1.2) , (1,2,2,1), (1,2,2,2), (2,1,1,1), (2,1,1,2), (2,1 ,2,1), (2,1,2,2), (2,2,1,1), (2,2,1,2), (2,2,2,1), (2,2 ,2,2), (3,1,1,1), (3,1,1,2), (3,1,2,1), (3,1,2,2), (3,2,1,1), (3,2,1,2), (3,2,2,1), (4,1,1,1), (4,1,1,2), (4,1,2,1),

(4.2.1.1) ; The transmitting end can transmit 3 kinds of abnormal flow number allocation, including: (4,1,2,2),

(4.2.1.2), (4, 2, 2, 1). The receiver converts (4, 1, 2, 2) to (1, 3, 1, 1), converts (4, 2, 1, 2) to (1, 1, 3, 1), ^1 ( 4, 2, 2, 1) is converted to (1, 1, 1, 3).

Secondly, the method for indicating the number of user flows provided by this embodiment considers that the flow number allocation information is transmitted in the form shown in Table 25, and the distribution of 21+3=24 flow numbers can be transmitted in the form of Table 25. Among them, 21 kinds of normal flow number distribution, including: (1,1,2,4), (1,1,3,3), (1,1,4,2), (1,2,1, 4 ), (1,2,2,3), (1,2,3,2), (1,2,4,1), (1,3,1,3), (1,3,2,2 ),

(1.3.3.1) , (1,4,1,2), (1,4,2,1), (2,1,1,4), (2,1,2,3), (2,1 ,3,2), (2,1,4,1), (2,2,1,3), (2,2,3,1), (2,3,1,2), (2,3 , 2,1), (2,4,1,1), note that the transmitting end only transmits the number of streams of the first three STAs, and the number of streams of the fourth STA is calculated by the receiving end; the transmitting end can also transmit three kinds of abnormalities. The number of streams is allocated, including: ( 1,3,4), ( 1,4,3), ( 1,4,4), which are processed by the receiving end and correspond to the number of streams (3, 3, 1 respectively) , 1), (3, 1, 3, 1 ), (3, 1, 1, 3 ).

Finally, the method for indicating the number of user flows provided in this embodiment considers that the flow number allocation information is transmitted in the form shown in Table 24, and the distribution of 9+3=13 flow numbers can be transmitted in the form of Table 24. Among them, 9 kinds of normal flow number distribution, including: (1,1,1,4), (1,1,2,3),

(1.1.3.2) , (1,1,4,1), (1,2,1,3), (1,2,3,1), (1,3,1,2), (1,3 , 2,1), (1,4,1,1); The transmitter can also transmit three kinds of abnormal flow number distribution, including: ( 2,4,4,3 ), ( 2,4,3,1 ) , ( 2,3,4,1 ), which are processed by the receiving end and correspond to the stream number assignment ( 2,1,1,3 ), ( 2,1,3,1 ), ( 2,3,1 ,1 ).

The method for indicating the number of user flows provided by the embodiment of the present invention can reduce the number of bits occupied by the number of streams of each user according to the number of streams of non-zero users in the user set, and further reduce the number of bits occupied by the number of streams of each user. The number of bits occupied by the entire stream number allocation information saves bit resources of information transmission and network communication resources.

As shown in FIG. 19, an embodiment of the present invention further provides a method for obtaining a user flow number, including:

Step 1901: Receive flow allocation information sent by the communication peer end.

In step 1902, the number of flows allocated by the local user is obtained according to the indication information included in the flow number allocation information and the number of flows corresponding to the user whose flow number is non-zero, and the indication information is used to indicate The number of users whose number of streams is non-zero and the user number.

It should be noted that, if the flow number allocation information structure received in step 1901 is as shown in Table 24-26, step 1902 first determines whether the flow number allocation information is transmitted by the abnormal flow number allocation, and then obtains the current end according to the result. The number of streams assigned by the user.

Specifically, if the flow number allocation information structure received in step 1901 is as shown in Table 24, step 1902 may include: decoding bl 5-M 8 to obtain a flow number N2 corresponding to a user whose second flow number is non-zero The number of streams N3 corresponding to the third stream with a non-zero number of users, the number of streams corresponding to the user whose number of streams is non-zero, Nl = l, and the total number of streams is 7, and the user corresponding to the fourth stream is non-zero. The number of flows N4=7-( N1+N2+N3 ) =6- ( N2+N3 ); If N4<1 is equivalent to (N2+N3)>5, let Nl=2, if N2 is 4 then set N2 = 1 otherwise unchanged, if N3 is 4 then set N3 = 1 otherwise unchanged, and N4 = 5 - (N2 + N3).

Alternatively, if the stream number allocation information structure received in step 1901 is as shown in Table 25, step 1902 may include: decoding bl4-bl 8 to obtain the number of streams N1 corresponding to the first to third streams having a non-zero number of users. , N2, N3; according to Nl, N2, N3, the number of streams corresponding to the fourth stream with a non-zero number of users is N4 =8-( Ν1+Ν2+Ν3 ); if N4 = 8-(Ν1+Ν2+Ν3)< 1 Equivalent to (Nl+N2+N3)>7, then judge whether N1 is equal to 1; if N1 is not equal to 1, then the exception is due to the received bit sequence error; if N1 is equal to 1, then this exception It is also used to indicate the number of streams. Let Nl=3, if N2 is 4, then N2 = 1 otherwise, if N3 is 4, then N3 = 1 otherwise, then N4=8-(N1+ N2+N3).

Alternatively, if the flow number allocation information structure received in step 1901 is as shown in Table 26, step 1902 may include: decoding bl 5-bl 8 to obtain the number of streams corresponding to the first to fourth non-zero users. Nl, N2, N3, N4; If (N1+N2+N3+ N4)>8 occurs, let Nl = N1-3 or let Nl = l, the two are completely equivalent; for 1 bit of N2, N3 And N4, if any of them is b, then b is subtracted from b and then a binary 0 is added to obtain the value as the corresponding stream number.

The method for obtaining the number of user streams according to the embodiment of the present invention can reduce the number of bits occupied by the number of streams of each user according to the number of streams of non-zero users in the user set, and further reduce the number of bits occupied by the number of streams of each user. The number of bits occupied by the entire stream number allocation information saves bit resources of information transmission and network communication resources. The embodiment of the invention further provides a communication device, including:

a determining module, configured to determine, according to the number of flows allocated to users in the user set, the number of users whose number of flows in the user set is non-zero, wherein the user set includes four users; and a sending module, configured to Determining, by the module, the number of users whose number of flows is non-zero, and sending the flow number allocation information to the communication peer end, where the flow number allocation information includes the indication information and the number of flows corresponding to the user whose flow number is non-zero, The indication information is used to indicate that the number of streams is non-zero. It should be noted that, in actual use, multiple modules divided by the communication device provided by the embodiments of the present invention may also have similar functions with the multiple modules. The module or function module is implemented, and will not be described here.

The communication device provided by the embodiment of the present invention can reduce the number of bits occupied by the number of streams of each user according to the number of streams of non-zero users in the user set, and further reduce the number of streams. The number of bits occupied by the allocation information saves the bit resources of information transmission and network communication resources. The method and communication device for indicating and acquiring the number of user streams provided by the embodiments of the present invention may be applied to a system that needs to allocate a flow number to a user, such as a multi-user MIMO system or the like.

As mentioned earlier, an indicator is a bit.

The present invention further discloses a method for expressing stream number allocation information by 11 bits, and referring to Table 27, a method for expressing stream number allocation information by 11 bits (bOO, bl0-bl9). The first indicator, the second indicator, and the third indicator are respectively represented by the bitmaps of the three bits (bOO, blO, and bll). In this embodiment, the kth indicator is set to 1 to indicate the kth number of streams. The user whose value is 0 is the user whose distribution number reaches the distribution threshold, and the kth indication flag is set to 0, indicating that the user whose kth flow number is 0 is not the user whose flow number reaches the distribution threshold; the above k value may be 1 Or 2 or 3. It is generally considered that the left-to-right indication flag bits (bOO, blO, and bll) are sequentially referred to as the first, second, and third indicator flags. The remaining 8 bits (bl2-bl9) are used to indicate the number of streams of each user, wherein the 8 streams indicate that every 2 bits in the bits constitute a stream number indicating bit group, and the number of streams per user (0-3) A stream number is used to indicate a bit group, that is, 2 bits. The distribution threshold is 4. If there is a fourth user whose number of flows is 0, the first indication identifier, the second indication identifier, and the third indication identifier are modulo 2 added to obtain a fourth indication identifier, where the fourth indication identifier indicates that the fourth flow number is The user of 0 is the user whose number of streams reaches the assigned threshold (1 means reach, 0 means not reached).

Table 27:

Further, the indication identifier in the bit sequence formed by the combination of the indication identifier and the bit in the flow number indication bit group is a high bit, and the flow number indicates that the bit in the bit group is a low bit. In this paper, according to the general habit, the left and right of the table reflect the order of the bit sequence, that is, the left is high. Right in the low position〇

In the following, for the method described in Table 27, various more specific embodiments in various cases are given. In the respective embodiments, it is assumed that the usual binary is used.

A specific implementation is shown in Table 28. The number of streams of user 1 is 01, that is, 1 stream. The number of streams of the user 2 indicates that the bit group is 00, which is the first stream number indicating bit group with a value of 00. Therefore, the stream number indicates that the bit group indicates the number of streams of the user together with the first indication flag b00, and An indicator is placed in the upper position, and the number of streams indicates that the bit in the bit group is low; thus the number of streams of user 2 is 100, that is, 4 streams. The number of streams of user 3 is 10, that is, 2 streams. The number of streams of the user 4 indicates that the bit group is 00, which is a stream number indicating bit group with a second value of 00. Therefore, the stream number indicating bit group and the second indication flag blO together indicate the number of streams of the user, and the number of The two indication flags are placed in the upper position, and the stream number indicates that the bits in the bit group are low; thus the number of streams of the user 2 is 000, that is, 0 streams. It is easy to see that the third indicator flag bll is not used in this embodiment.

Table 28:

Another specific implementation is shown in Table 29a. It is easy to see that the number of streams of the users 1, 2, and 3 indicates that the bit groups are all 00, so the number of streams of the users 1, 2, and 3 indicates that the bit groups are respectively indicated with the first, second, and third indications (ie, b00, bl0, bll). ) — Indicates the number of streams for the corresponding user. Correspondingly, the number of streams of users 1, 2, 3 is 000, 100, 000, that is, the number of streams is 0, 4, 0. Since the number of streams of the user 4 indicates that the bit group is also 00, we need to modulate the first, 2, and 3 indications (ie, b00, bl0, bll) to obtain a fourth indicator, that is, b00+bl0=0+l= l, the result 1 is added with bll modulo 2, l+bll = l+0=l. All fourth indications are 1, and the corresponding user 4 has a flow number of 100, that is, a stream number of 4.

Table 29a:

A further embodiment is shown in Table 29b. It is easy to see that the number of streams of the users 1, 2, and 3 indicates that the bit group is 00, so the number of streams of the users 1, 2, 3 indicates that the bit groups are respectively indicated with the first, second, and third indicators (ie, b00, bl0, bll). ) — Indicates the number of streams for the corresponding user. Phase It should be noted that the number of streams of users 1, 2, and 3 is 000, 100, 100, that is, the number of streams is 0, 4, 4. Since the number of streams of user 4 indicates that the bit group is also 00, we need to modulo 2 the first, second, and third indication flags (ie, b00, bl0, bll) to obtain the fourth indication flag, that is, b00+bl0=0+l= l, the result 1 is added with bll modulo 2, 1 + 1=0. All fourth indicator identifiers are 0, and the corresponding user 4 has a stream number of 000, that is, a stream number of zero.

Table 29b:

The two indications in the embodiments described in Tables 14, 15 may in some cases be managed to be placed in the remaining bits of the stream indication bit group, correspondingly we get the following 9-bit embodiment, with 9 bits (M0-bl8) indicates the flow number assignment information. In the following embodiments, some of the methods of the embodiments described in Tables 1, 2, 3, and 4 are also used.

First, the first bit (blO) is whether there is an identifier of 4 users, which is simply referred to as the number of streams. When the flag bit blO is 0, it means that there is no user with a stream number of 4. When the flag bit blO is 1, it indicates that there is a user with a stream number of 4, that is, there are at least one user with a stream number of 4. .

The implementation of the number of streams 4 with the flag bit blO being 0 is shown in Table 30. If blO is 0, there is no user with a stream number of 4. The remaining 8 bits in the stream number allocation information (bll-bl8) are used to represent the number of streams of each user in the user set, wherein there are 4 users (user 1 - user 4) The number of streams per user is represented by 2 bits, which are referred to as stream number indicating bit groups; it is easy to see that table 30 is identical to Table 1. We give more specific details, assuming that the usual binary is used, then one stream indicates that the bit group is 00, 01, 10, and 11, respectively, indicating that the number of streams is 0, 1, 2, 3. Note the table 30 to the table? And in the related description, the meanings of the first indication identifier and the first indication identifier are exactly the same, and the meanings of the second indication identifier and the second indication identifier are completely the same.

Table 30:

When the stream number 4 existence flag bit blO is 1, there is at least one user whose stream number is 4. There are two cases at this time. The first case is that there is only one stream with a number of streams greater than or equal to 3. Household, this is equivalent to the presence of a user with a flow number equal to 4 and no user with a flow number equal to 3; in the second case, there are 2 users with a flow number greater than or equal to 3, which is equivalent to the presence of 1 flow The number is equal to 4 users and there are users with the same number of streams equal to 3 or 4.

The flow number 4 has the case where the flag bit blO is 1 (i.e., the user who exists and only has 1 stream number greater than or equal to 3) is shown in Table 31. As shown in Table 31, a blO of 1 indicates that at least one user with a stream number of 4 exists, and the remaining 8 bits (bll-bl8) in the stream number allocation information are used to represent the number of streams of each user in the user set, wherein, there are 4 The number of streams per user (User 1 - User 4) is represented by 2 bits, and the 2 bits are referred to as stream number indicating bit groups. Assuming that the usual binary is used, then one stream indicates that the bit group is 00, 01, 10, and 11, respectively, indicating that the number of streams is 0, 1, 2, 4. Note that unlike Table 30 above, in Table 31, one stream number indicates that the bit group is 11 indicates that the stream number is 4.

Table 31:

For the flow number 4, there are case 2 when the identification bit blO is 1 (that is, there are 2 users whose flow number is greater than or equal to 3), and there are only 3 possible flow number distributions, that is, the flow number distribution 1 is recorded as (4, 3, 0, 0), indicating that the number of streams of four users is 4, 3, 0, 0; the distribution of stream number 2 is recorded as (4, 3, 1, 0), indicating that the number of streams of four users is 4 , 3, 1, 0; The flow number distribution 3 is recorded as (4, 4, 0, 0), indicating that the flow numbers of the four users are 4, 4, 0, 0, respectively. Note that each of the above-mentioned flow number distributions is only a combination of the order of the four users' flow numbers, and there are various differences between the four users and the four flow numbers of the one flow number distribution. - Correspondence, it is well known that the number of different - corresponding relationships is less than or equal to the number of all possible permutations of four elements, that is, 24.

For the above three possible flow number distributions (4, 3, 0, 0), (4, 3, 1, 0) and (4, 4, 0, 0), we notice that in addition to the number of streams greater than or equal to 3 The number of streams of two users other than users may only be 0 or 1, that is, the number of streams of two users with a stream number less than 3 may only be 0 or 1, but not 2. Thus, for each of the two users whose number of streams is less than 3, we can use the corresponding number of streams containing 2 bits to indicate that 1 bit in the bit group indicates the number of streams, ie 0 or 1, and the number of streams indicates The remaining 1 bit in the bit group, One of the first indicator and the second indicator in the embodiment of Tables 14, 15 can be placed. The number of streams of the two users whose number of streams is less than 3 indicates that the remaining 1 bit of the bit group can be placed in the indications in the embodiment of Tables 14 and 15, so that in the embodiments described in Tables 14, 15 The first indicator identifier and the second indicator identifier may be placed in the remaining 1 bit of the stream number indicating bit group of the two users whose number of streams is less than 3, for example, the first indicator identifier is placed in the stream number less than 3 The number of streams of the first user indicates one of the remaining bits of the bit group, and the second indicator is placed in the remaining one of the number of stream indication bits of the second user whose number of streams is less than three. In addition, if the first indication flag is 1, and the number of streams of the first user whose number of streams is less than 3 indicates that the number of streams of the bit group indicates that the bit is also 1, the receiver cannot receive the bit sequence 11 and cannot determine that it is It consists of 1 indicator and 1 stream number, or indicates that a user's stream is 3 or 4. Similarly, if the second indication flag is 1, and the number of streams of the second user whose number of streams is less than 3 indicates that the stream number of the bit group indicates that the bit is also 1, the receiving end cannot receive the bit sequence 11 and cannot judge it. Is it composed of 1 indicator and 1 stream number, or indicates that a user's stream is 3 or 4. Therefore, in view of the above situation, we need to make corresponding corrections to the embodiment, and only when the flow number distribution is (4, 3, 1, 0), it is necessary to do the above-mentioned correction.

The flow number 4 has an indication that the case where the bl O is 1 (i.e., the case where there are two users whose number of streams is greater than or equal to 3) is as shown in Tables 32 and 33. In the embodiments shown in Tables 32 and 33, it is assumed that the normal binary is used, and each of the two users whose number of streams is less than 3 is indicated by the corresponding number of streams containing 2 bits. The lower 1 bit indicates that the number of streams is 0 or 1, and the normal binary is used, that is, bit 0 indicates the stream number 0, and bit 1 indicates the stream number 1.

In the embodiment described in Table 32, each of the two users whose number of streams is less than 3 is indicated by a corresponding one of the bit placement tables 14 and 15 indicating the upper bits of the bit group. The indication identifier in the embodiment; at the same time, the first indication identifier is placed in the remaining 1 bit of the stream number indicating bit group of the first user whose number of streams is less than 3, and the second indicator identifier is placed in the stream number The number of streams of the second user less than 3 indicates the remaining 1 bit of the bit group. When the embodiment described in Table 32 is used, any of the following cases and Case B does not occur. The situation is: the first indicator is 1 and the number of streams is less than 3. The number of streams of one user indicates one bit of the lower bit in the bit group, that is, the stream number indicates that the bit is also 1. In the case B, the second indication flag is 1, and the number of streams of the second user whose number of streams is less than 3 indicates the lower one of the bits in the bit group, that is, the stream number indicates that the bit is also 1. When the above-described situation or case B occurs in the embodiment described in Table 32, the embodiment described in Table 33 is used.

Greater than or equal to 3 As described above, the embodiment described in Table 33 is used to avoid the occurrence of the following, that is, if the embodiment described in Table 32 is used, the above situation or case B may occur, thereby The receiver cannot decode correctly. The implementation described in Table 33 is as follows. As is easy to see from Table 33, in the embodiment described in Table 33, the number of streams including 2 bits corresponding to the user whose first stream number is less than 3 indicates the lower one of the bits in the bit group, and not only the number of streams is 0. Or 1, indicating the first indication identifier; and the number of streams corresponding to the user whose first stream number is less than 3 indicates that the upper 1 bit of the bit group is always set to 0. Similarly, the number of streams including 2 bits corresponding to the user whose second stream number is less than 3 indicates the lower one of the bits in the bit group, not only indicating the number of streams, that is, 0 or 1, but also indicating the second indication flag; The number of streams corresponding to users whose stream number is less than 3 indicates that the upper 1 bit of the bit group is always set to 0.

The above Table 30, Table 31, Table 32, Table 33, that is, the embodiments described in Tables 30 to 33, the hardware implementation of the transmitting end and the receiving end are quite simple, and we will give an explanation below. The usual hardware is implemented in binary. We assume that the hardware of the transmitting end and the receiving end use the 12 bits shown in Table 34 to represent the flow information of four STAs. The 12 bits shown in Table 34 use the usual binary as much as possible, and the only difference from the usual binary is that it is represented by 111 instead of 100. Note that in the table, the three bits from the upper to the lower of the stream information of the i-th user are Ni[2], Ni[l] and Ni[0], where i is equal to 1, 2, 3 or 4.

Table 34:

First, a method of realizing the transmitting end, that is, a method of obtaining 9 bits actually transmitted by 12 bits shown in Table 34, is given. The four bits Nl[2], N2[2], N3[2], N4[2] are first summed, and the result of the summation is bl0 of the embodiment described in Tables 30 to 33. Said or known operation, usually, a number of bits are summed, as long as one of the bits is 1, the result is 1; only all bits are 0, the result is 0. If blO is 0, then the 9 bits actually transmitted by the transmitting end are as shown in Table 30, and the values of bll, bl2, bl3, bl4, bl5, bl6, bl7, and bl8 in Table 30 are respectively Nl[l], N1[ 0], N2[l], N2[0], N3[l], N3[0], N4[1], N4[0]. If blO is 1, the transmitting end indicates the bit group (Nl[l], N1[0]) for the number of streams, the stream number indicates the bit group (N2[l], N2[0]), and the stream number indicates the bit group (N3[ l], N3[0]), the stream number indicates the bit group (N4[l], N4[0]). The four stream numbers indicate the bit group, and the number of bit sequences 11 is determined. If the number of 11 is 1 Then, the 9 bits actually transmitted by the transmitting end are as shown in Table 31, and the values of bll, bl2, bl3, bl4, bl5, bl6, bl7, and bl8 in Table 31 are Nl[l], N1[0], respectively. N2[l], N2[0], N3[l], N3[0], N4[l], N4[0]; if the above four stream numbers indicate that the number of bit sequences 11 in the bit group is 2, transmit The 9 bits actually transmitted by the terminal are as shown in Table 32 or Table 33, and the method of obtaining the actually transmitted 9 bits is given in the next paragraph.

This paragraph is 1 for blO and 4 streams indicate that the number of bit sequences 11 in the bit group is

In the case of 2, a method of obtaining 9 bits of actual transmission is given. The transmitting end finds the first stream number indicating bit group of bit sequence 11 (Ni[l], Ni[0] ), and its corresponding upper bit Ni[2] is used as the first indication flag, and then finds the second bit sequence. The stream number of 11 indicates the bit group (Nj[l], Nj[0]), and its corresponding upper bit Nj[2] is used as the second indication flag; note that i is equal to 1, 2, 3 or 4 and j is equal to 2, 3 or 4, while i is less than j. In addition, the transmitting end finds the first stream number indicating bit group (Nm[l], Nm[0]) which is not the bit sequence 11, and then judges the first indication flags Ni[2] and Nm[0]. Whether all is 1, if not, the value of Nm[l] is set to the first indication flag Ni[2]; if it is (ie, both Ni[2] and Nm[0] bits are 1), Nm The value of [l] is set to zero. The originator finds the second number of streams indicating the bit sequence 11 (Nk[l], Nk[0]), and determines whether the two bits of the second indication flags Nj[2] and Nk[0] are all 1. If not, set the value of Nk[l] to the second indication flag Nj[2]; if yes (ie, both bits Nj[2] and Nk[0] are 1), put Nk[l] The value is set to 0; it is easy to see that m is equal to 1, 2, 3 or 4, while m is not equal to i or j; and k is equal to 1, 2, 3 or 4, and k is not equal to i Or j, and k is less than m. Correspondingly, the actual transmitted 9 bits obtained by the transmitting end are as shown in Table 32 or Table 33, and the values of bll, bl2, bl3, bl4, bl5, bl6, bl7, and bl8 are respectively obtained in this paragraph. Nl[l], N1[0], N2[l], N2[0], N3[l], N3[0], N4[l], N4[0].

Note that in the step described in the previous paragraph, when the transmitting end determines whether the two bits of the first indication flag Ni[2] and Nm[0] are all 1, if the judgment result is yes, then the table 33 is inevitably used. The illustrated embodiment, so that it is actually possible to skip "judge the second indication flag Nj[2] And whether the two bits of Nk[0] are all 1", the value of direct 4 bar Nk[l] is set to 0. If the transmitting end judges the first indication signs Ni[2] and Nm[0] When all the bits are 1, the judgment result is no, and the transmitting end judges whether the two bits of the second indication flags Nj[2] and Nk[0] are all 1, and the judgment result is yes, then the table 33 is actually obtained. The embodiment shown is: when the transmitting end determines whether the two bits of the first indication signs Ni[2] and Nm[0] are all 1, the judgment result is no, and the transmitting end determines the second indication flag Nj[2] Whether or not the two bits of Nk[0] are all 1, and the result of the determination is also no, the embodiment shown in Table 32 is obtained.

Below we give the implementation of the receiver. The nine bits actually received by the receiving end are as shown in any of Table 30, Table 31, Table 32 and Table 33. For the sake of simplicity of the description, we show the 9 bits actually received by the receiving end as shown in Table 35. It is easy to see that bll, bl2, bl3, bl4, bl5, bl6, bl7, and bl8 in Table 30, Table 31, Table 32, and Table 33 are equivalent to Nl[l], N1[0] shown in Table 35, respectively. N2[l], N2[0], N3[l], N3[0], N4[l], N4[0].

Table 35:

The implementation of the receiving end can be regarded as 9 bits shown in Table 35, and 12 bits shown in Table 34 are obtained, thereby obtaining a binary representation of all four user streams. The receiving end first sets the four highest-order bits N1[2], N2[2], N3[2] and N4[2] in Table 34 to 0 as the default value; in the subsequent processing, the above-mentioned highest The default value of the bit bits may change.

The receiving end judges the value of blO. If blO is 0, the receiving end finds the 8th highest and lowest bits in Table 34, that is, Nl[l], N1[0], N2[l], N2[0], N3[l in Table 34 ], N3[0], N4[l], N4[0], respectively equal to Nl[l], N1[0], N2[l], N2[0], N3[l], N3[ in Table 35 0], N4[l], N4[0]. If blO is 1, the receiving end indicates the bit group (Nl[l], N1[0]) for the number of streams, the stream number indicates the bit group (N2[l], N2[0]), and the stream number indicates the bit group (N3) [l], N3[0]), the stream number indicates the bit group (N4[l], N4[0]). The four stream numbers indicate the bit group, and the number of the bit sequence 11 is determined, if the number of 11 is 1, the bit sequence of 11 is the same as the blO, indicating the number of streams of the corresponding STA, which is equivalent to the number of streams of the corresponding STA indicated by the 1 bit sequence of 11 is 4; , Let the number of streams indicating the bit sequence 11 indicate that the bit group is (Ni[l], Ni[0]), then correspondingly set Ni[2] in Table 34 to 1, and then, Nl in Table 34 [ l], N1[0], N2[l], N2[0], N3[l], N3[0], N4[l], N4[0], respectively equal to Nl[l], N1 in Table 35 [0], N2[l], N2[0], N3[l], N3[0], N4[l], N4[0]. If the above four stream numbers indicate that the number of bit sequences 11 in the bit group is 2, we need to use the steps described in the next paragraph.

In this case, the blO received by the receiving end is 0, and the received 4 stream numbers indicate that the number of bit sequences 11 in the bit group is 2, and the implementation steps are given. The first and second stream number indicating bit groups of the bit sequence 11 are respectively recorded as (Ni[l], Ni[0]) and (Nj[l], Nj[0]), which are easy to see, corresponding The first indication flag Ni[2] and the second indication flag Nj[2] are required to be indicated, respectively, which indicate whether the stream number of the bit sequence 11 indicates whether the bit group represents the stream number 3 or the stream number 4. The receiving end finds the first and second stream number indicating bit groups 11 (Nm[l], Nm[0]) and (Nk[l], Nk[0]), and then judges the two The number of streams indicates whether the higher bits Nm[l] and Nk[l] of the bit group are all 0. If not, the first and second streams that are not the bit sequence 11 indicate the higher bits of the bit group, ie, Nm. [l] and Nk[l], respectively, a first indication flag Ni[2] and a second indication flag Nj[2]; if so, the first and second stream number indication bits that are not the bit sequence 11 The lower bits of the group, Nm[0] and Nk[0], are the first indication flag Ni[2] and the second indication flag Nj[2], respectively. Thereafter, the first and second stream numbers not indicating the bit sequence 11 indicate that the upper bits of the bit group, i.e., Nm[l] and Nk[l], are set to zero. . Finally, let Nl[l], N1[0], N2[l], N2[0], N3[l], N3[0], N4[1], N4[0] in Table 34 to be sought. Nl[l], N1[0], N2[l], N2[0], N3[l], N3[0], N4[l], N4[0, respectively, in Table 35 after the above steps are processed. As can be seen from the above description, the two most significant bits in Table 34, namely the first indication flag Ni[2] and the second indication flag Nj[2], are also assigned in the processing step of the appeal.

Further describe the contents of Table 14 below:

The flow number allocation information includes: two indication identifiers (ie, bits blO and b11, one indication identifier is one bit as described above) and eight flow number indication bits (bl2-bl9), wherein eight flow number indication bits are each Two bits form a stream number indicating bit group, and each stream number indicates a bit group to indicate the number of streams of one STA.

If the number of the flow indicator indicates that the value of the bit group is the first indication value, the value corresponding to the first indication value is the number of flows of the STA corresponding to the bit group indicating the bit group; if the number of the flow indicator indicates the value of the bit group a second indication value, the value represented by the bit sequence formed by the combination of the 1 indicating identifier bit and the bit in the stream number indicating bit group is the STA corresponding to the bit number indicating the bit group Number of streams. Specifically, the specific examples given above are given in Table 15.

The first indication value of the value of the specific stream number indicating bit group may be 00 or 01 or 10, and the second indication value is 11. If the number of streams indicates that the value of the bit group is the second indication value, the number of streams indicates that the number of streams of the STA corresponding to the bit group is 3 or 4. If the number of the flow indicator indicates that the value of the bit group is the second indication value, the value represented by the bit sequence formed by combining one of the two indication identifiers with the bits in the stream number indication bit group is the stream number indication bit. The number of streams of the STA corresponding to the group: if the number of streams indicates that the value of the bit group is the second indication value, and the number of streams indicates that the bit group is the first stream indicating the bit group of the second indication value, Determining, by the indication identifier, the number of flows of the STA, the number of flows indicating that the value of the bit group is a second indication value, and the number of the flow indicating that the bit group is the second The number of streams indicating the value indicates a bit group, and the number of streams of the STA is determined according to the second indication identifier and the stream number indication bit group. A bit in the bit sequence corresponding to one of the two indicator identifiers and the bit sequence in the stream indicator group is a high bit, and the number of the stream indicates that the bit in the bit group is Low.

The method for indicating the number of user flows according to the embodiment of the present invention is capable of transmitting the number of streams by using the first indication identifier and the second indication identifier to indicate the number of streams reaching the user who allocates the threshold according to the number of streams of each user in the user set.
