In order to solve the shared more problem of bit resource of transmission fluxion assignment information, the embodiment of the present invention provides a kind of method and communicator of indicating and obtaining user's fluxion.

As shown in Figure 2, the method for the indicating user fluxion that the embodiment of the present invention provides, comprising:

Step 201, according to the fluxion of the user assignment in user set, determine user gather in fluxion arrive user's number of allocation threshold, wherein, user's set comprises 4 users, allocation threshold is 4;

Step 202, the user's number that arrives allocation threshold according to fluxion sends fluxion assignment information to Correspondent Node, wherein, if it is 0 that fluxion arrives user's number of allocation threshold, described fluxion assignment information comprises the fluxion of each user in the first sign and described user set, described the first sign is used to indicate in described user's set and does not comprise the user that fluxion arrives allocation threshold, if it is not 0 that fluxion arrives user's number of allocation threshold, described fluxion assignment information comprises the second sign, fluxion arrives user's sequence number indication information of allocation threshold, and all the other users' fluxion, described the second sign is used to indicate in described user's set and comprises the user that fluxion arrives allocation threshold.

In the present embodiment, user's number of fluxion arrival allocation threshold mostly is 2 most.When user's number of fluxion arrival allocation threshold is 1, user's sequence number indication information that fluxion arrives allocation threshold can be user's sequence number; When user's number of fluxion arrival allocation threshold is 2, user's sequence number indication information that fluxion arrives allocation threshold can comprise: the indication information that the number of users that arrives fluxion allocation threshold is 2, fluxion arrives the first user sequence number of allocation threshold and second user's sequence number indication that fluxion arrives allocation threshold, in the present embodiment, the indication information that the number of users that arrives fluxion allocation threshold is 2 can adopt user gather in total user's fluxion be not more than the principle setting of total allocation threshold value, wherein, described total allocation threshold value is 8.Alternatively, when user's number of fluxion arrival allocation threshold is 2, if the user's that indication comprises fluxion arrival allocation threshold the indication that is designated comprises the sign that fluxion arrives user's number of allocation threshold, user's sequence number indication information that fluxion arrives allocation threshold can also be respectively user's sequence number that fluxion arrives two users of allocation threshold.

Particularly, for example: can represent fluxion assignment information with 9 bits (b10-b18).Wherein, the 1st bit (b10) is flag, when this flag is 0, represents the first sign, when this flag bit is 1, represents the second sign;

As shown in table 1, b10 is 0 o'clock, remains 8 bits (b11-b18) and gather each user's fluxion for representing user in fluxion assignment information, and wherein, the fluxion that has each user of 4 users (user 1-user 4) represents with 2 bits;

Table 1:

As shown in table 2, b10 is 1 o'clock, if only comprise the user that 1 fluxion arrives allocation threshold, user's sequence number that user's sequence number indication information of fluxion arrival allocation threshold is this user, owing to having 4 users in user's set, so represent that with 2 bits (b11 and b12) fluxion arrives user's sequence number of allocation threshold, residue 6 bits are for representing other users' fluxion, wherein, each user's fluxion represents with 2 bits;

As shown in table 3, b10 is 1 o'clock, if comprise the user that 2 fluxions arrive allocation threshold, user's sequence number indication information that fluxion arrives allocation threshold can comprise: the indication information that the number of users that arrives fluxion allocation threshold is 2, fluxion arrives the first user sequence number of allocation threshold and second user's sequence number indication information that fluxion arrives allocation threshold.

In the present embodiment, in the indication information employing user set that the number of users that arrives fluxion allocation threshold is 2, total user's fluxion is not more than the principle setting of total allocation threshold value, and wherein, described total allocation threshold value is 8.

Particularly, as shown in table 3,2 bits (b11 and b12) are set to the first user sequence number that fluxion arrives allocation threshold; Fluxion is that 0 bit corresponding to user is set to arrive the indication information that the number of users of fluxion allocation threshold is 2, the present embodiment adopts principle that in user's set, total user's fluxion is not more than total allocation threshold value to arrange to arrive the indication information that the number of users of fluxion allocation threshold is 2, with 11 expressions; Bit corresponding to the second user that fluxion arrives allocation threshold is set to second user's sequence number indication information, and the present embodiment represents with other numerical value (as 00) except 11.

It should be noted that, if the fluxion assignment information structure that step 1901 receives is as shown in table 24-table 26, what first step 1902 judged whether fluxion assignment information transmit is abnormal fluxion distribution condition, then according to result, is retrieved as the fluxion of local terminal user assignment.

Particularly, if the fluxion assignment information structure that step 1901 receives is shown in table 24, step 1902 can comprise: b15-b18 is decoded, obtain fluxion N2 corresponding to the user of second fluxion non-zero and the fluxion N3 corresponding to user of the 3rd fluxion non-zero, the fluxion N1=1 corresponding according to the user of first fluxion non-zero, total fluxion is 7, obtains fluxion N4=7-(the N1+N2+N3)=6-(N2+N3) corresponding to user of the 4th fluxion non-zero; If N4 < 1 is equivalent to the situation of (N2+N3) > 5, occur, allow N1=2, if 4 of N2 put N2=1 otherwise be constant, if N3 is 4, put N3=1 otherwise constant, and N4=5-(N2+N3).

Or if the fluxion assignment information structure that step 1901 receives is as shown in Table 25, step 1902 can comprise: b14-b18 is decoded, obtain corresponding fluxion N1, N2, the N3 of user of first to the 3rd fluxion non-zero; According to N1, N2, N3, obtain the fluxion N4=8-(N1+N2+N3) corresponding to user of the 4th fluxion non-zero; If N4=8-(N1+N2+N3) < 1 is equivalent to the situation of (N1+N2+N3) > 7, occur, judge whether N1 equals 1; If N1 is not equal to 1, this is due to the bit sequence mistake receiving extremely; If N1 equals 1, this is extremely also used for representing fluxion distribution, and the corresponding N1=3 that allows, if 4 of N2 put N2=1 otherwise be constant, if 4 of N3 put N3=1 otherwise be constant, then calculates N4=8-(N1+N2+N3).

Or if the fluxion assignment information structure that step 1901 receives is shown in table 26, step 1902 can comprise: b15-b18 is decoded, obtain corresponding fluxion N1, N2, N3, the N4 of user of first to fourth fluxion non-zero; If (N1+N2+N3+N4) situation of > 8 occurs, allow N1=N1-3 or allow N1=1, the two is equivalence completely; For the N2 of 1 bit, N3 and N4, establishing arbitrary among them is b, b is got after non-and mends in the back a binary zero, obtains value as corresponding fluxion.

The communicator that the embodiment of the present invention provides, can be according to user's number transmission fluxion assignment information of fluxion non-zero in user's set, reduced to transmit each user's the shared bit number of fluxion information, further reduce the shared bit number of whole fluxion assignment information, saved bit resource and the network service resource of communication.

The indication that the embodiment of the present invention provides and obtain the method for user's fluxion and communicator can be applied in need to the system for user assignment fluxion in, as multi-user MIMO system etc.

As previously mentioned, a sign is a bit.

The invention process discloses a kind of method that use 11 bits represent fluxion assignment information again, consults table 27, represents the method for fluxion assignment information with 11 bits (b00, b10-b19).Wherein, with 3 bit (b00, b10 and b11) bitmap represent respectively first sign the second sign and the 3rd sign, in the present embodiment, it is the user that fluxion arrives allocation threshold that k sign is set to user that k fluxion of 1 expression is 0, and k sign to be set to the user that k fluxion of 0 expression is 0 be not the user of fluxion arrival allocation threshold; Above-mentioned k value can be 1 or 2 or 3.It is generally acknowledged that sign bit (b00, b10 and b11) is from left to right called the 1st, 2,3 signs successively.Adopt residue 8 bits (b12-b19) to represent each user's fluxion, in wherein said 8 fluxion indication bit, every 2 bits form a fluxion indication bit group, and each user's fluxion (0-3) is that 2 bits represent by a fluxion indication bit group.Described allocation threshold is 4.If there is the 4th user that fluxion is 0, first sign the second sign and the 3rd sign being carried out to mould 2 adds, obtain the 4th sign, the 4th sign represents that the 4th user that fluxion is 0 is user's (1 represents to reach, and 0 represents not reach) that fluxion arrives allocation threshold.

Table 27:

Further, sign described in the bit sequence constituting jointly with the bit in sign and this fluxion indication bit group is high-order, and the bit in described fluxion indication bit group is low level.According to general custom, the order of bit sequence has been embodied in the left and right in table in this article, left in a high position, right at low level.

For the method described in table 27, provide the more detailed various specific embodiments in various situations below, in each embodiment, suppose and adopt common 2 systems.

A specific embodiment is shown in table 28.User 1 fluxion is 01, i.e. 1 stream.User 2 fluxion indication bit group is 00, it is that first value is 00 fluxion indication bit group, therefore the fluxion that this fluxion indication bit group is indicated this user together with the first sign b00, and the first sign is placed on a high position, and bit in fluxion indication bit group is low level; Thereby user 2 fluxion is 100, i.e. 4 streams.User 3 fluxion is 10, i.e. 2 streams.User 4 fluxion indication bit group is 00, it is the fluxion indication bit group that second value is 00, therefore the fluxion that this fluxion indication bit group is indicated this user together with the second sign b10, and the second sign is placed on a high position, and bit in fluxion indication bit group is low level; Thereby user 2 fluxion is 000, i.e. 0 stream.Easily see, the 3rd sign b11 does not use in this specific embodiment.

Table 28:

Another specific embodiment is as shown in table 29a.Easily see, user 1,2, and 3 fluxion indication bit group is all 00, so user 1,2,3 fluxion indication bit group is indicated respectively the fluxion of respective user together with the 1st, 2,3 signs (being b00, b10, b11).Accordingly, user 1,2, and 3 fluxion is respectively 000,100,000, and fluxion 0,4, and 0.Because user 4 fluxion indication bit group is also 00, we need to the 1st, 2,3 signs (be b00, b10, b11) carry out mould 2 and obtained the 4th sign, be b00+b10=0+1=1, its result 1 adds with b11 mould 2 again, 1+b11=1+0=1.All the 4th signs are 1, and corresponding user's 4 fluxion is 100, and fluxion 4.

Table 29a:

Another specific embodiment is as shown in table 29b.Easily see, user 1,2, and 3 fluxion indication bit group is all 00, so user 1,2,3 fluxion indication bit group is indicated respectively the fluxion of respective user together with the 1st, 2,3 signs (being b00, b10, b11).Accordingly, user 1,2, and 3 fluxion is respectively 000,100,100, and fluxion 0,4, and 4.Because user 4 fluxion indication bit group is also 00, we need to carry out mould 2 first, second and third sign (being b00, b10, b11) and be obtained the 4th sign, i.e. b00+b10=0+1=1, and its result 1 adds with b11 mould 2 again, 1+1=0.All the 4th signs are 0, and corresponding user's 4 fluxion is 000, and fluxion 0.

Table 29b:

Two signs in table 14,15 described embodiment, can manage to be in some cases placed in the remaining bits of fluxion indication bit group, corresponding we obtain obtaining 9 bit embodiment below, with 9 bits (b10-b18), represent fluxion assignment information.In the following examples, also used a part of method of table 1,2,3,4 described embodiments.

First, the 1st bit (b10) is 4 users' flag for whether there is fluxion, referred to as fluxion 4, has flag.When this flag b10 is 0, representing not exist fluxion is 4 user; When this flag b10 is 1, representing to exist fluxion is 4 user, that is to say, having at least one fluxion is 4 user.

It is that 0 embodiment is shown in table 30 that fluxion 4 exists flag b10.B10 is that not have fluxion be 4 user in 0 expression, in fluxion assignment information, remain 8 bits (b11-b18) and gather each user's fluxion for representing user, wherein, the fluxion that has each user of 4 users (user 1-user 4) represents with 2 bits, and described 2 bits are called fluxion indication bit group; Easily see that table 30 is identical with table 1.We provide details more specifically, suppose and adopt common 2 systems, and 1 fluxion indication bit group is 00,01,10,11 to represent that respectively fluxion is 0,1,2,3 so.Is attention arrived table at table 30? with and relevant narration in, the first sign is identical with the implication of the 1st sign, and the second sign is identical with the implication of the 2nd sign.

Table 30:

It is 1 o'clock that fluxion 4 exists flag b10, has at least 1 user that fluxion is 4.Now have two kinds of situations, situation one is, exists and only exists 1 fluxion to be more than or equal to 3 user, and this is equivalent to and has 1 user that fluxion equals 4 user and do not exist fluxion to equal 3; The 2nd kind of situation be, exists 2 fluxions to be more than or equal to 3 user, and this is equivalent to and exists 1 fluxion to equal 4 user and have another user who equals 3 or 4 of fluxion.

It is that the embodiment of situation one (exist and only exist 1 fluxion to be more than or equal to 3 user) of 1 o'clock is shown in table 31 that fluxion 4 exists flag b10.Shown in table 31, b10 is that 1 expression at least exists the user that 1 fluxion is 4, in fluxion assignment information, remain 8 bits (b11-b18) and gather each user's fluxion for representing user, wherein, the fluxion that has each user of 4 users (user 1-user 4) represents with 2 bits, and described 2 bits are called fluxion indication bit group.Suppose and adopt common 2 systems, 1 fluxion indication bit group is 00,01,10,11 to represent that respectively fluxion is 0,1,2,4 so.Note differently from aforesaid table 30, in table 31,1 fluxion indication bit group is that 11 expression fluxions are 4.

Table 31:

For fluxion 4, having flag b10 is the situation two (existing 2 fluxions to be more than or equal to 3 user) of 1 o'clock, has and only have 3 possible fluxions to distribute, that is: fluxion distributes and 1 is designated as (4,3,0,0), 4 users' of expression fluxion is respectively 4,3,0,0; Fluxion distribution 2 is designated as (4,3,1,0), represents that 4 users' fluxion is respectively 4,3,1,0; Fluxion distribution 3 is designated as (4,4,0,0), represents that 4 users' fluxion is respectively 4,4,0,0.Notice that each above-mentioned fluxion distributes, a combination that there is no ordinal relation of 4 users' that just provide fluxion, between 4 fluxions that 4 users and a described fluxion distribute, can there is various one-to-one relationship, as everyone knows, the number that the number of described various one-to-one relationship is less than or equal to 4 all possible arrangements of element 24.

For above-mentioned 3 possible fluxions, distribute (4,3,0,0), (4,3,1,0) and (4,4,0,0), we notice that the fluxion of two users except fluxion is more than or equal to two users of 3 may be only 0 or 1, that is to say, the fluxion that fluxion is less than two users of 3 may be only 0 or 1, and can not be 2.Thereby, for described fluxion, be less than each of two users of 3, we can use 1 bit in the fluxion indication bit group that comprises 2 bits of its correspondence to represent its fluxion 0 or 1, and remaining 1 bit in fluxion indication bit group can be used for 1 in the first sign in embodiment and the second sign described in placement table 14,15.The fluxion indication bit group that described fluxion is less than two users of 3 all exists 1 remaining bit can placement table 14, sign described in 15 in embodiment, so table 14, the first sign in 15 described embodiment and the second sign can be placed in 1 bit of fluxion indication bit group remainder that described fluxion is less than two users of 3, for example, the first sign is placed in 1 bit of fluxion indication bit group remainder that described fluxion is less than 3 the 1st user, and the second sign is placed in 1 bit of fluxion indication bit group remainder that described fluxion is less than 3 the 2nd user.In addition, if the first sign is 1, and being less than the above-mentioned fluxion of 3 the 1st user's fluxion indication bit group, fluxion represents that bit is also 1, receiving terminal is received after this bit sequence 11 so, cannot judge that it represents that by 1 sign and 1 fluxion bit forms, the fluxion of still indicating a user is 3 or 4.In like manner, if the second sign is 1, and being less than the above-mentioned fluxion of 3 the 2nd user's fluxion indication bit group, fluxion represents that bit is also 1, receiving terminal is received after this bit sequence 11 so, cannot judge that it represents that by 1 sign and 1 fluxion bit forms, the fluxion of still indicating a user is 3 or 4.So for above-mentioned situation, we need to do corresponding correction to embodiment, and are only distributed as the situation of (4,3,1,0) in fluxion, just may need to do above-mentioned correction.

It is that the embodiment of situation two (existing 2 fluxions to be more than or equal to 3 user) of 1 o'clock is as shown in table 32 and 33 that fluxion 4 exists flag b10.In the embodiment shown in table 32 and 33, suppose and adopt common 2 systems, and described fluxion is less than two users of 3 each, all use 1 bit of low level in the corresponding fluxion indication bit group that comprises 2 bits to represent that its fluxion is 0 or 1, adopt common 2 systems, be that bit 0 represents fluxion 0, and bit 1 represent fluxion 1.

In the embodiment described in table 32, described fluxion is less than each of two users of 3, all uses the sign in embodiment described in 1 bit placement table 14,15 high-order in the corresponding fluxion indication bit group that comprises 2 bits; Meanwhile, the first sign is placed in 1 bit of fluxion indication bit group remainder that described fluxion is less than 3 the 1st user, and the second sign is placed in 1 bit of fluxion indication bit group remainder that described fluxion is less than 3 the 2nd user.When the embodiment described in adopting table 32, can there is not following situation first and any one in situation second.Described situation first is: the first sign is 1, and fluxion is less than 1 bit of low level in 3 the 1st user's fluxion indication bit group, and above-mentioned fluxion represents that bit is also 1.Described situation second is: the second sign is 1, and fluxion is less than 1 bit of low level in 3 the 2nd user's fluxion indication bit group, and above-mentioned fluxion represents that bit is also 1.When above-mentioned situation first or situation second appear in the embodiment described in employing table 32, adopt the embodiment described in table 33.

Table 32:

As previously mentioned, adopting the embodiment described in table 33, is the generation for fear of following thing, if that is: adopt the embodiment described in table 32, there will be above-mentioned situation first or situation second, thereby receiving terminal cannot be correctly decoded.Embodiment described in table 33 is as follows.By table 33, easily seen, in the embodiment described in table 33, the 1st fluxion is less than 1 bit of low level in the fluxion indication bit group that comprises 2 bits corresponding to 3 user, not only represents its fluxion 0 or 1, also represents the first sign; And the 1st fluxion is less than 1 high-order bit in fluxion indication bit group corresponding to 3 user and is always set to 0.Similarly, the 2nd fluxion is less than 1 bit of low level in the fluxion indication bit group that comprises 2 bits corresponding to 3 user, not only represents its fluxion 0 or 1, also represents the second sign; And the 2nd fluxion is less than 1 high-order bit in fluxion indication bit group corresponding to 3 user and is always set to 0.

Table 33:

Above table 30, table 31, table 32, table 33, table 30 is to embodiment described in 33, the hardware of its transmitting terminal and receiving terminal is realized all suitable simple, below we provide explanation.Common hardware is all to realize with 2 systems, and we suppose in the hardware of transmitting terminal and receiving terminal, all adopt 12 bits shown in table 34, represents the fluxion information of 4 STA.12 bits shown in table 34 adopt common 2 systems as far as possible, and are with the unique difference of common 2 systems, represent 4 with 111, rather than represent 4 with 100.Notice that in table, 3 bits from a high position to low level of i user's fluxion information are Ni[2 successively], Ni[1] and Ni[0], i equals 1,2 here, and 3 or 4.

Table 34:

The implementation method of given first transmitting terminal, is obtained the method for 9 bits of actual transmission by 12 bits shown in table 34.First to N1[2], N2[2], N3[2], N4[2] these 4 bits ask or, ask or result, be exactly that table 30 is to the b10 of embodiment described in 33.Described asks or known operation, common, several bits ask or, as long as wherein to have 1 bit be 1, result is 1 so; Only having all bits is all 0, and result is only 0.If b10 is 0,9 of transmitting terminal actual transmission bits are shown in table 30 so, the b11 in table 30, and b12, b13, b14, b15, b16, b17, the value of b18 is respectively N1[1], N1[0], N2[1], N2[0] and, N3[1], N3[0] and, N4[1], N4[0].If b10 is 1, transmitting terminal for fluxion indication bit group (N1[1], N1[0]), fluxion indication bit group (N2[1], N2[0]), fluxion indication bit group (N3[1], N3[0]), fluxion indication bit group (N4[1], N4[0]) these 4 fluxion indication bit groups, judge the wherein number of bit sequence 11, if 11 number is 1, 9 of transmitting terminal actual transmission bits are shown in table 31 so, and b11 in table 31, b12, b13, b14, b15, b16, b17, the value of b18 is respectively N1[1], N1[0], N2[1], N2[0], N3[1], N3[0], N4[1], N4[0], if the number of bit sequence 11 is 2 in above-mentioned 4 fluxion indication bit groups, 9 bits of transmitting terminal actual transmission are as shown in table 32 or table 33, and the method for trying to achieve 9 bits of actual transmission provides in next section.

This section of number that is bit sequence 11 in 1 and 4 fluxion indication bit group for b10 is 2 situation, provides the method for 9 bits of trying to achieve actual transmission.Transmitting terminal find the 1st for the fluxion indication bit group of bit sequence 11 (Ni[1], Ni[0]), the high-order Ni[2 of its correspondence] as the first sign, find again the 2nd for the fluxion indication bit group of bit sequence 11 (Nj[1], Nj[0]), the high-order Nj[2 of its correspondence] as the 2nd sign; Notice that above-mentioned i equals 1,2,3 or 4 and j equal 2,3 or 4, simultaneously i is less than j.In addition, transmitting terminal finds the 1st to be not the fluxion indication bit group of bit sequence 11 (Nm[1], Nm[0]), then judges the first sign Ni[2] and Nm[0] whether these two bits be all 1, if not, Nm[1] value be made as the first sign Ni[2]; If (be Ni[2] and Nm[0] these two bits are all 1), Nm[1] value be made as 0.Make a start and find the 2nd to be not the fluxion indication bit group of bit sequence 11 (Nk[1], Nk[0]), then judge the 2nd sign Nj[2] and Nk[0] whether these two bits be all 1, if not, Nk[1] value be made as the 2nd sign Nj[2]; If (be Nj[2] and Nk[0] these two bits are all 1), Nk[1] value be made as 0; Easily see, described m equals 1,2, and 3 or 4, m is not equal to i or j simultaneously; And described k equals 1,2,3 or 4, k is not equal to i or j simultaneously, and k is less than m.Accordingly, 9 bits of the actual transmission that transmitting terminal is tried to achieve as shown in table 32 or table 33, b11 wherein, b12, b13, b14, b15, b16, b17, the value of b18 is respectively the N1[1 trying to achieve at this section], N1[0], N2[1], N2[0], N3[1], N3[0] and, N4[1], N4[0].

Note, in the step described in the preceding paragraph, transmitting terminal judges the first sign Ni[2] and Nm[0] whether these two bits be all 1 o'clock, if judgment result is that, be, must adopt the embodiment shown in table 33 so, thereby in fact can skip " judge the 2nd sign Nj[2] and Nk[0] whether these two bits be all 1 " this step, directly Nk[1] value be made as 0.And if transmitting terminal judges the first sign Ni[2] and Nm[0] whether these two bits be all 1 o'clock, the determination result is NO, and transmitting terminal judges the 2nd sign Nj[2] and Nk[0] whether these two bits be all 1, judgment result is that to be, so in fact obtains the embodiment shown in table 33.Only have transmitting terminal to judge the first sign Ni[2] and Nm[0] whether these two bits be all 1 o'clock, the determination result is NO, simultaneously transmitting terminal judges the 2nd sign Nj[2] and Nk[0] whether these two bits be all 1, judged result is also no, just obtains the embodiment shown in table 32.

Below we provide the implementation method of receiving terminal.Actual 9 bits that receive of receiving terminal are as table 30, and table 31, shown in arbitrary in table 32 and table 33.Simple and clear for what explain, we represent actual 9 bits that receive of receiving terminal shown in table 35.Easily see, table 30, table 31, the b11 in table 32 and table 33, b12, b13, b14, b15, b16, b17, b18 is equal to respectively the N1[1 shown in table 35], N1[0], N2[1], N2[0] and, N3[1], N3[0] and, N4[1], N4[0].

Table 35:

The realization of receiving terminal, can regard as by 9 bits shown in table 35, obtains 12 bits shown in table 34, thereby 2 systems that obtain all 4 user's fluxions represent.Receiving terminal is first 4 most significant bit N1[2 in table 34], N2[2], N3[2] and N4[2] be set to 0, as default value; In follow-up processing, the default value of above-mentioned most significant bit may change.

The value of receiving terminal judgement b10.If b10 is 0, receiving terminal is tried to achieve in table 34 8 high positions and lowest order, that is, the N1[1 in table 34], N1[0], N2[1] and, N2[0], N3[1], N3[0], N4[1] and, N4[0], equal respectively the N1[1 in table 35] and, N1[0], N2[1], N2[0], N3[1] and, N3[0], N4[1] and, N4[0].If b10 is 1, receiving terminal again for fluxion indication bit group (N1[1], N1[0]), fluxion indication bit group (N2[1], N2[0]), fluxion indication bit group (N3[1], N3[0]), fluxion indication bit group (N4[1], N4[0]) these 4 fluxion indication bit groups, judge the wherein number of bit sequence 11, if 11 number is 1, the fluxion that so described 1 bit sequence that is 11 is indicated corresponding STA together with b10, this is equivalent to, and the fluxion of the corresponding STA of described 1 bit sequence indication that is 11 is 4; Accordingly, establishing is that 1 fluxion indication bit group of bit sequence 11 is (Ni[1], Ni[0]), so accordingly the Ni[2 in table 34] be set to 1, then, the N1[1 in table 34], N1[0] and, N2[1], N2[0], N3[1], N3[0] and, N4[1], N4[0], equal respectively the N1[1 in table 35], N1[0], N2[1], N2[0], N3[1], N3[0], N4[1], N4[0].If the number of bit sequence 11 is 2 in above-mentioned 4 fluxion indication bit groups, we need to adopt the step described in next section.

This section of b10 receiving for receiving terminal is 0, and in 4 fluxion indication bit groups receiving, the number of bit sequence 11 is situations of 2, provides implementation step.The 1st and the 2nd for the fluxion indication bit group of bit sequence 11 be designated as respectively (Ni[1], Ni[0]) and (Nj[1], Nj[0]), easily see, the first corresponding sign Ni[2] and the 2nd sign Nj[2] need to try to achieve, the fluxion indication bit group that they are designated as respectively bit sequence 11 represents that fluxion 3 also means fluxion 4.Receiving terminal find the 1st and the 2nd not for the fluxion indication bit group of bit sequence 11 (Nm[1], Nm[0]) and (Nk[1], Nk[0]), judge again the high bit Nm[1 of these two fluxion indication bit groups] and Nk[1] whether be all 0, if not, the 1st and the 2nd is not the high bit of the fluxion indication bit group of bit sequence 11, i.e. Nm[1] and Nk[1], be respectively the first sign Ni[2] and the 2nd sign Nj[2]; If so, the 1st and the 2nd be not bit sequence 11 fluxion indication bit group compared with low level, i.e. Nm[0] and Nk[0], be respectively the first sign Ni[2] and the 2nd sign Nj[2].After this, the 1st and the 2nd, be not a high position for the fluxion indication bit group of bit sequence 11, i.e. Nm[1] and Nk[1], be all set to 0.。Finally, allow N1[1 in table 34 to be asked], N1[0], N2[1], N2[0], N3[1], N3[0] and, N4[1], N4[0], equal respectively the N1[1 in the table 35 after above-mentioned steps is processed], N1[0], N2[1], N2[0], N3[1], N3[0], N4[1], N4[0], and can be known by narration above, two most significant bits in table 34, i.e. the first sign Ni[2] and the 2nd sign Nj[2], also appeal treatment step in by assignment.

Below further the content of his-and-hers watches 14 describe again one time:

Fluxion assignment information comprises: 2 signs (are bit b10 and b11, a sign is a bit as previously mentioned) and 8 fluxion indication bit (b12-b19), wherein in 8 fluxion indication bit, every 2 bits form a fluxion indication bit group, and each fluxion indication bit group is in order to indicate the fluxion of a STA.

If the value of fluxion indication bit group is the first indicated value, numerical value corresponding to this first indicated value is the fluxion of STA corresponding to this fluxion indication bit group; If the value of described fluxion indication bit group is the second indicated value, the fluxion that the represented numerical value of bit sequence constituting jointly with bit in this fluxion indication bit group according to the 1 sign bit in described 2 signs is STA corresponding to this fluxion indication bit group.Specifically in conjunction with aforementioned as the instantiation providing in table 15.
