How to determine the transmission signal of the user of first moment access, it is as detailed below in second example.
In the first instance, if first moment is initial time at the rear moment, above-mentioned steps 101 can be with
Including following sub-steps 1011, sub-step 1012 and sub-step 1013.
Sub-step 1011, the second target user for determining the access of third moment and first moment maintenance access, it is described
The third moment is the previous moment at first moment.
Continue to use above for example, if the first moment be the t-1 moment, the second moment be t moment, then when third

Determine the access of third moment and first moment maintain access the second target user mode, and hereinafter
The access of the first moment is determined in (step 102) and the second moment maintained the mode of the first object user of access identical, specifically really
It is as detailed below to determine mode, wouldn't repeat herein.
Sub-step 1012, the Eigen Structure by second target user when accessing at the third moment, are determined as institute
State Eigen Structure of second target user when accessing at second moment.
That is, since the second target user accesses at the t-2 moment and maintains access at the t-1 moment, and it is same in the short time
The Eigen Structure of user will not change, therefore, can be by Eigen Structure of second target user when accessing at the t-2 moment
Pk(0)(t-2), the Eigen Structure P as second target user when accessing at the t-1 momentk(0)(t-1)。
Sub-step 1013, the channel state information that the first moment new access user is determined according to predetermined manner, and root
According to the channel state information of the first moment new access user, the Eigen Structure of the first moment new access user is determined.
Wherein, determined according to predetermined manner the mode of the channel state information of the first moment new access user with hereafter
In (sub-step 1014) channel state information of the user of the first moment access determined according to the predetermined manner
Mode it is identical, wouldn't also repeat herein, it is as detailed below.
In second example, if first moment is initial time (such as 0ms), above-mentioned steps 101 can be with
Including following sub-steps 1014 and sub-step 1015.
Sub-step 1014, according to the predetermined manner, determine the channel status of the user of the first moment access
Information.
In more detail, sub-step 1014 may include following sub-steps 141, sub-step 142 and sub-step 143.
Sub-step 141, the total number of users for determining the first moment access.
At each access moment, the user of access sends signal to the network equipment (base station), due to requiring different use in PDMA
The average signal-to-noise ratio (Signal to Noise Ratio, SNR) that family reaches base station is equal, therefore, in one example, can be with
The total number of users that each moment access is estimated by the total power signal that base station receives, can specifically be estimated by following formula：
Wherein, K (t) indicates the total number of users of t moment access, and W indicates the total power signal that base station receives,It indicates to use
Family signal reaches the mean power of base station, andIt is system preset parameter.
In this way, for example, if the first moment be 0ms where, the first moment total number of users of access can be with
It is expressed as K (0).
It should also be noted that, the total number of users in a user group of hypothesis system is K, base station is distributed total to user
Bandwidth is N number of PRB, has unique Eigen Structure to meet each user in K user, the number N of the PRB of distribution needs
Meet following conditions：
Wherein, symbolIt is rounded in expression；K >=K (t), namely in t moment, the total number of users of access base station may not be
All users in the user group of system belonging to the base station.
In order to meet the condition, in one example, base station can be pre-designed K group orthogonal guide frequency on N number of PRB, and
Distribute to K user.
Sub-step 142, the total number of users be equal to 1 in the case where, according to first moment access user hair
It send pilot frequency information and receives pilot frequency information, determine the channel state information of the user of the first moment access.
For example, indicating that the total number of users of access base station is 1 in the case where K (0)=1, user 1 being denoted as, and can
To determine the channel state information of the user of the first moment access according to the following formula：
Wherein, ys1(0) indicate that (namely base station connects in 0ms for the reception pilot frequency information of the user 1 of the first moment (0ms) access
The pilot frequency information of the user 1 received), s1(0) the transmission pilot frequency information of the user 1 of the first moment (0ms) access is indicated,Table
Show the channel state information of the user 1 of the first moment (0ms) access.
Correspondingly, determining the letter of the user 1 of the first moment (0ms) access in K (0)=1 and above-mentioned sub-step 142
Channel state informationIn the case where, the reception signal of the above user according to first moment access, and
The channel state information of the user of the first moment access determines the transmission signal of the user of the first moment access, tool
Body can be acquired by following relational expressions：
Wherein, y1(0) the reception signal of the user 1 of the first moment access, x are indicated1(0) use of the first moment access is indicated
The transmission signal at family.
Sub-step 143, the total number of users be greater than 1 in the case where, according to serial interference elimination (Successive
Interference Cancellation, SIC) detect the channel state information for determining the user of the first moment access.
For example, indicating that the total number of users of access base station is greater than 1, in K (0) a user in the case where K (0) is greater than 1
Kth (0) a user can be denoted as user k (0), wherein (0)=1 k, 2 ..., K (0), and can be detected according to SIC technology true
The channel state information of the user k (0) of fixed first moment (0ms) access.
The channel that the user k (0) for determining the first moment (0ms) access is detected using SIC technology is briefly described below
The substantially process of status information.
As described above, since the customer service packet of average arrival simultaneously is less than 1.5/ms, and the feature of each user
Pattern is constant in a short time, therefore the case where user individually occupies certain PRB can occurs to maximum probability, in this way, base station
The user information that the PRB of detection coverlet user occupancy can be first passed through, demodulates multiple user signals, and acquire the first moment (example
Such as 0ms) access user k (0) channel state informationAnd Eigen Structure Pk(0)(0)。
Wherein, the resource block of coverlet user occupancy is determined according to the pattern matrix estimated.
When SIC technology determines multiple user signals, the transmission signal for individually occupying the user of a resource block is first determined, then really
Determine the transmission signal of other users.Specifically, determine multi-user occupy PRB subscriber signal (the transmission signal of user) it
Before, the subscriber signal for individually occupying a PRB is first subtracted according to pattern matrix, then determines the subscriber signal of remaining users again.
For example, (n-1)th PRB be only by a user occupancy (such as user 1), then the transmission signal of user 1 can be first found out, n-th
A PRB by two users simultaneously occupy (such as user 1 and user 2), then can before determining the transmission signal of user 2,
It needs first to subtract the signal of user 1, then determines the transmission signal of user 2.
For example, at the first moment (0ms), there are following relationships for base station：
ys(0)=H (0) s1(0)
Wherein, ys(0)=[ys1(0),ys2(0) ..., ysK(0)(0)], with above, ys1(0) indicate that the first moment (0ms) connects
The reception pilot frequency information of the user 1 entered, others and so on；It is same above,Indicate the channel state information of the user 1 of the first moment (0ms) access, others and so on.
It can be in the hope of the channel state information of (0) user k based on above-mentioned relation
Correspondingly, K (0) is greater than 1 and above-mentioned sub-step 143 determines the user k (0) of the first moment (0ms) access
Channel state informationIn the case where, the reception of the above user according to first moment access is believed
Number and first moment access user channel state information, determine the transmission of the user of first moment access
Signal, it is specific as follows：
Assuming that only one user on the 1st PRB, and be denoted as user 1, then the access of the first moment can be acquired based on following formula
User 1 transmission signal x1(0)：
Then according to pattern matrix P (0), the PRB by two users while occupancy is found, for example the 2nd PRB, then
The transmission signal x of the user 2 of the first moment access can be acquired according to following two relational expressions2(0)：
And
Wherein, ys2(0) total reception signal that the 2nd PRB is received, y are indicateds2,2(0) indicate what the 2nd PRB was received
The reception signal of user 2,Indicate the channel state information of user 2,Indicate the channel state information of user 1.
And so on, it can be in the hope of the transmission signal for the other users that the first moment was accessed.
Sub-step 1015, according to first moment access user channel state information, determine first moment
The Eigen Structure of the user of access.
The example in sub-step 1014 is continued to use, specifically can use the use that the first moment (0ms) access is calculated in following formula
The Eigen Structure at family：
Wherein,hk,n(0) channel coefficients, Rayleigh distributed are indicated；K (0) indicates that K (0) is a
Kth (0) a user in user, n=1,2 ..., N；Indicate the channel of the user k (0) of the first moment (0ms) access
Status information；Pk(0)(0) Eigen Structure of the user k (0) of the first moment (0ms) access is indicated.
Fig. 2 schematically illustrate it is above-mentioned detected using SIC technology determine the user of each moment access Eigen Structure,
Channel state information and the process for sending signal.
Above by two examples, the process for dividing briefing to determine the Eigen Structure of the user of the first moment access,
In practical applications, those skilled in the art can also determine that the embodiment of the present application is not limited this using other modes.
Step 102, the first object user for determining the first moment access and the maintenance access of the second moment.
Wherein, second moment is the later moment in time at first moment.
With in step 101, it is assumed that the first moment was t-1 moment (such as 0ms), then the second moment can be t moment
(such as 1ms).
Below with reference to an example to determining that the process of first object user is illustrated in step 102, it is based on and this mistake
Process as journey class can also determine the second target user in sub-step 1011 above.
Specifically, as an example, above-mentioned steps 102 may include：User in first set is recycled and is executed
User in second set is determined as the first object until having traversed the user in the first set by given step
User；Wherein, the first set is the set of user's composition of first moment access；The specified step is executed in circulation
Before rapid, the second set is sky.
Since the first moment can indicate that the second moment can be indicated with t with t-1, therefore, the user in first set is total
Number can indicate that after circulation has executed above-mentioned given step, the total number of users in second set can be indicated with R with K (t-1).
If the total number of users of the second moment access is K (t), then a user of this K (t) includes R the first moment accesses and the second moment
Maintain first object user and a new access users of K (t)-R of access.
As shown in Fig. 2, above-mentioned given step can specifically include following steps：
Step 201, the Eigen Structure according to active user when accessing at first moment, determine that the active user exists
Channel state information when second moment is accessed.
In one example, it can be connect according to active user k (0) is determined in above-mentioned steps 101 at first moment
The Eigen Structure P of fashionable Eigen Structurek(0)(0), Eigen Structure of the active user k (0) in the access of the second moment is determined
Pk(0)(1), it is assumed here that Pk(0)(1) it is equal to Pk(0)(0).Namely assume first that K (0) a user accessed at the first moment (0ms)
It is all accessed at the second moment, then according to the Eigen Structure P of the user of the first moment accessk(0)(0) and following steps
Whether 202-205 verifying k (0) actually accesses at the second moment, and when the judging result of step 205 is no, when determining first
The user k (0) of access is carved in the practical access of the second moment.
Optionally, in another example, step 201 may include：According to the network equipment to first moment
The demodulation sequence of the user of access, recycles the user in the first set and executes given step.For example, can be according to network
Equipment recycles the user in the first set and executes the given step, successively to the demodulation sequence of the 0ms user accessed
Determine whether the first moment K (0) a user of access all accesses at the second moment.
Step 202, the channel state information according to the active user when accessing at second moment, determine described in work as
Transmission signal of the preceding user when accessing at second moment.
For example, it is assumed that active user is the user 1 of 0ms access, user 1 can be solved according to the demodulation sequence of 0ms
It adjusts, demodulates transmission signal x of the user 1 when accessing at second moment1It (1), specifically can be according to following two relational expressions
Demodulate x1(1)：
And
Wherein, P1(1)=P1(0),hk,n(1) expression channel coefficients, Rayleigh distributed, n=1,
2,...,N；Indicate the channel state information of the user 1 of the second moment (1ms) access；P1(1) the second moment (1ms) is indicated
The Eigen Structure of the user 1 of access.
Step 203, the channel state information according to the active user when accessing at first moment, to described current
Transmission signal of the user when accessing at second moment is reconstructed, and obtains reconstruction signal.
For example, the channel state information according to user 1 when accessing at the first momentTo x1(1) it is reconstructed, obtains
Following reconstruction signal：
Step 204, the resultant signal arrived according to the reconstruction signal and the network equipment in second reception, really
Hair of remaining user when accessing at second moment in the user of the fixed second moment access in addition to the active user
The number of delivering letters.
Determine maintained in remaining user access user (other first objects user) second moment access when
The mode for sending signal, with above-mentioned determining x1(1) mode is identical, and details are not described herein again；Determine that newly access is used in remaining user
The mode of transmission signal of the family when accessing at second moment, with the user's of above determining initial time (0ms) access
The mode for sending signal is identical, also repeats no more herein.
Whether transmission signal of remaining the described user that step 205, judgement are determined when accessing at second moment goes out
It is wrong；If do not malfunctioned, 206 are thened follow the steps；Otherwise 201 are returned to step, until having traversed the use in the first set
Circulation is exited at family.
In one example, the mode that can use even-odd check judges the transmission signal of remaining the above-mentioned user determined
Whether malfunction, if do not malfunctioned, assert that active user accesses at the first moment and maintains to access at the second moment；Otherwise,
Determine that active user accesses at the first moment but there is no access at the second moment.
Under normal conditions, an even-odd check can be specially set in the signal (binary data) that user sends to base station
, the number of " 1 " is odd number or even number in the binary data for ensuring to send with it.Such as：Send one group of 8 binary system
Number, it is assumed that first is parity check bit, and latter seven are data bit, using odd, then：It is b'0000111 when sending data
When, 1 sent in data has 3, is odd number, check bit is then 0 at this time, and the data being actually sent out are exactly b'000000111；
When sending data is b'000110,1 sent in data has 2, is even number, check bit is then 1 at this time, is actually sent out
Data are exactly b'10000110.
Wherein, judge whether transmission signal of remaining the described user determined when accessing at second moment malfunctions,
It specifically can be and judge whether the transmission signal of whole users in remaining user malfunctions, be also possible to judge part in remaining user
Whether the transmission new signal of user malfunctions.
The active user is stored in the second set by step 206.
After exiting circulation, the user in second set can be determined as to first object user, and will be in second set
Total number of users be determined as the quantity of first object user.
The embodiment of the present application has been illustrated with the process of determining first object user, in practical applications, this field
Technical staff can also determine the access of the first moment by other means and the second moment maintained the first object user of access, this
Application embodiment does not limit this.
