Embodiment
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.The present invention taking in multi-user's multiple-input and multiple-output (Multi-input Multi-output, MIMO) system as example, access point AP need to and multiple STA between while communicating, AP is STA distributing user data fluxions.In actual applications, AP also can think a special STA, Correspondent Node AP and STA each other under some scenes.In an embodiment, think that the total maximum antenna number 8 of common STA can not increase, thereby total maximum fluxion is 8.
Each user's fluxion is not more than 8, and total fluxion is to be also not more than 8, so, when MU-MIMO, if there is certain user's fluxion to be greater than 4, should only have 1 user's fluxion to be greater than 4, and other user's fluxion must be less than or equal to 3 simultaneously; And in other user, only have at most 1 user's fluxion to be more than or equal to 2, and remaining user's fluxion must be less than 2.
In the first embodiment, carrying out the method can be AP.AP uses the fluxion assignment information indicating user fluxion of 11 bit compositions, consult table 1, bit b00-b19 totally 11 bit indicating user fluxions for the method, wherein b00 is the first sign, the first sign comprises 1 bit, and whether the first sign is used to indicate has user's fluxion to be greater than 4.If the first sign is 1, be illustrated in this group user and have user's fluxion to be greater than 4, if the first sign is 0, is illustrated in this group user and does not have user's fluxion to be greater than 4.Certainly in practical application, can arranging the first sign b00 and be 0 fluxion that indicates user, to be greater than 4, b00 be that 1 expression does not have user's fluxion to be greater than 4.
Table 1
Consult table 2, in fluxion assignment information, also comprise that the second sign, the second sign comprise 2 bit b10, b11.Other a fluxion indication bit group of every 2 bits composition of 8 bits, each fluxion indication bit group is used to indicate a user's fluxion.Such as bit group 1 is for fluxion of the 1st user etc.If the first sign is 1 in the present embodiment, is illustrated in this group user and has user's fluxion to be greater than 4.
Table 2
If the first sign b00 is 0, do not have user's fluxion to be greater than 4.In the time not having user's fluxion to be greater than 4, whether the fluxion that equals 3 user by the second sign instruction fluxion is 4.
The second sign comprises 2 indication bit (being bit b10 and b11).In addition also have 8 fluxion indication bit (b12-b19), a fluxion indication bit group of every 2 bits composition in these 8 fluxion indication bit, 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 represented numerical value of bit sequence constituting jointly with the bit in this fluxion indication bit group according to 1 indication bit in described the second sign is the fluxion of STA corresponding to this fluxion indication bit group.Concrete combination is as the instantiation providing in table 3.
The first indicated value of the value of concrete fluxion indication bit group can be that 00 or 01 or 10, the second indicated values are 11.If the value of fluxion indication bit group is the second indicated value, the fluxion of STA corresponding to this fluxion indication bit group is 3 or 4.If the value of fluxion indication bit group is the second indicated value, the represented numerical value of bit sequence constituting jointly with the bit in this fluxion indication bit group according to 1 indication bit in the second sign is the fluxion of STA corresponding to this fluxion indication bit group: if the value of fluxion indication bit group is the second indicated value, and this fluxion indication bit group is first fluxion indication bit group of getting described the second indicated value, combine according to the 1st sign (i.e. the 1st indication bit in the second sign) fluxion of determining this STA with described fluxion indication bit group, if the value of fluxion indication bit group is the second indicated value, and this fluxion indication bit group is second fluxion indication bit group of getting described the second indicated value, combine according to the 2nd sign (i.e. the 2nd indication bit in the second sign) fluxion of determining this STA with described fluxion indication bit group.1 bit of sign described in the bit sequence that bit in 1 corresponding 1 bit and this fluxion indication bit group in 2 signs constitutes jointly is for high-order, and the bit in fluxion indication bit group is low level.
Particularly, when fluxion assignment information is as shown in table 3, first step 1702 resolves b12-b19, obtains the fluxion of each user in user's set, and user 1 fluxion is 1, and user 2 fluxion is 3, and user 3 fluxion is 0, and user 4 fluxion is 3; Then according to the first sign b10=0 and the second sign b11=1, determine that the actual fluxion of user that second fluxion is 3 is 4, therefore actual fluxion of the user 4 is 4, if this end subscriber is user 4, the fluxion that is defined as local terminal user assignment is 4.
Table 3:
Note, in reality, possible b12-b19 has only indicated 1 user that fluxion is 3, and now b11 is nonsensical; Also may b12-b19 not indicating any fluxion is 3 user, and now b10 and b11 are nonsensical.Nonsensical for above-mentioned b11, or all nonsensical situations of b10 and b11, these nonsensical bits are set to 0 conventionally.Because the fluxion of the STA that the fluxion that b10 or b11 are 0 expression correspondence is 3 remains unchanged, thereby receiving terminal is for the b10 or the b11 that are 0, certainly do not need to carry out the processing that possible corresponding STA fluxion changes at subsequent step, thereby can reduce the implementation complexity of receiving terminal.
The most further embodiment, if the first sign b00 is 1, indicates that user's fluxion is greater than 4.Which user's fluxion the second sign indicates be greater than 4, can be any one user in 1-4 in reality, but should only have 1.Consult table 4,
Table 4
In fluxion assignment information, the first sign b00 1 indicates to be greater than the user of 4 streams, and which user's fluxion the second sign (b10, b11) indicates be greater than 4.4 users' of 8 bit instructions of remaining 4-11 fluxion, a fluxion indication bit group of 8 every 2 bits compositions of bit, each fluxion indication bit group is used to indicate a user's fluxion.Such as bit group 1 is for recording fluxion of the 1st user etc.The user who is greater than 4 by the second sign instruction fluxion.For example, if the second sign is 00,01,10,11, represent respectively that the 1st, 2,3,4 users indicate fluxion to be greater than 4.Be not more than 4 user for fluxion, represent with 00,01,10,11 that respectively fluxion is 0,1,2,3, because total fluxion is not more than 8, so in the time existing fluxion to be greater than 4 user, other user's fluxion is 3 to the maximum.The user who is greater than 4 for the second sign instruction fluxion, 01,10,11 represent respectively fluxion 5,6,7, further also can arrange to indicate this user's fluxion with 00 is 8.
Fluxion assignment information in the invention process is by 2 grades of indication informations, fluxion situation to user is distinguished, the each user's fluxion of accurate recording in all cases, and reduce 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.
In second embodiment, consult table 5, use the fluxion assignment information indicating user fluxion of 10 bits (b00-b18) composition, identical with embodiment mono-, the 1st bit b00 is that the first sign still indicates whether there is the user who is greater than 4 streams.
Table 5
In the present embodiment, the first sign b00 is that 0 expression does not have user's fluxion to be greater than 4.B00 is 0 in this example, and representing does not have user's fluxion to be greater than 4.
In the time not having user's fluxion to be greater than 4, the first sign b00 is 0.Fluxion assignment information is consulted table 6.
Table 6
Associative list 6, to be first used to indicate and whether to have fluxion be 4 users to the second sign (b10), is called again fluxion 4 and has flag.In the time that this flag b10 is 0, representing not exist fluxion is 4 user; In the time that this flag b10 is 1, representing to exist fluxion is 4 user, that is to say, having at least one fluxion is 4 user.In this example, the second sign b10 is 0.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, fluxion 2 bits that have the each user of 4 users (user 1-user 4) represent, described 2 bits are called fluxion indication bit group.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.The second sign b10 is 1 o'clock, 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.
The second sign b10 is within 1 o'clock, to be situation one (exist and only exist 1 fluxion to be more than or equal to 3 user).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, fluxion 2 bits that have the each user of 4 users (user 1-user 4) represent, 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.Can 1 fluxion indication bit group be that 11 expression fluxions are 4 in this example.
Having flag b10 for fluxion 4 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, one of 4 users' that just provide fluxion does not have the combination of ordinal relation, 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.
