Under spaced antenna base station, HSUPA user's E-PUCH is carried out to space division multiplexing, in different antenna coverage areas, use the identical different upstream data of E-PUCH resource transmission, can significantly promote the higher uplink bit rate of base station, but can bring as mentioned above, the up co-channel interference at E-PUCH place time slot between the antenna of space division multiplexing in base station.
Under non-space division multiplexing scene, PRRI can be limited by reference to the SNPL of HSUPA reporting of user in base station, thereby the transmitting power of constraint user uplink E-PUCH, and then control the interference to adjacent base station, but the scene of E-PUCH space division multiplexing in spaced antenna base station, how to control the interference between adjacent antenna, in existing standard, do not provide corresponding solution.

Embodiment
After space division multiplexing, there is no the problem of time slot up co-channel interference in E-PUCH place between corresponding mechanism control space division multiplexing antenna for the E-PUCH of HSUPA in spaced antenna base station, as shown in Figure 1, the method of carrying out the mandate of physical uplink channel power for space division multiplexing user that the present invention proposes, comprise: while distributing physical uplink channel authorization power for the space division multiplexing user of use high speed uplink data access business, determine space division multiplexing authorization power with described space division multiplexing user to the difference of the path loss of service antenna respectively according to described space division multiplexing user to the path loss of adjacent vacant point multiplex antenna.
Concrete, be that a space division multiplexing user (taking user ay as example) meets the following conditions at the space division multiplexing authorization power of the physical uplink channel of current time distribution:
AGP(n)≤Threshold(n)+ISO(n)-Pebase(n)-α(n) (1)
Wherein, AGP (n) represents that current time is the space division multiplexing authorization power of the physical uplink channel of space division multiplexing user a distribution, and unit is dBm;
The uplink interference controlling elements of the physical uplink channel of the enhancing dedicated channel of space division multiplexing user a described in Threshold (n) expression current time; This value is dynamic adjustable value, is provided with initial value Threshold
0, maximum of T hreshold
maxwith minimum value Threshold
min, arranging of initial value, maximum and minimum value is all relevant to the receiving demodulation ability of base station, according to the empirical value setting of base station equipment.Initial value is all identical to each user in base station.
The space division multiplexing user a that ISO (n) represents current time divides the path loss of multiplex antenna and the described space division multiplexing user difference to the path loss of service antenna to adjacent vacant.As shown in Figure 2, show the schematic diagram of two spaced antennas in a base station, the service antenna (or claiming optimal antenna) of user a, b belongs to antenna A and antenna B, and the adjacent antenna that B is a, the adjacent antenna that A is b.When a, b carry out space division multiplexing, what solid line represented is the useful signal of relative users, and what dotted line represented is interference signal.Under this scene, while distributing power mandate for user a, ISO (n) represents that the user a of current time is to the path loss PL of antenna B
a, B(n) with the path loss PL of user a to antenna A
a, A(n) difference; PL
a, Band PL (n)
a, A(n) be all on the occasion of, and PL
a, B(n) > PL
a, A(n), unit is dB.
When the service antenna of space division multiplexing user has multiple adjacent vacant point multiplex antenna, ISO (n) represents the minimum value during described space division multiplexing user is to the path loss of each adjacent vacant point multiplex antenna and described space division multiplexing user to the difference of the path loss of service antenna.
Pebase (n) represents that the base station, space division multiplexing user a place of current time receives space division multiplexing user a by strengthening the required minimal detectable power of minimum data piece of dedicated channel transmitting; This parameter is the parameter in existing standard, can change along with the upstream noise of E-PUCH place time slot and interference variations, and unit is dBm.
α (n) represents that the spreading factor of the physical uplink channel of described enhancing dedicated channel is SF
e-PUCHlogarithm value, this parameter is the parameter in existing standard, uses as correction value.As shown in the table, the function of use is 10*Log (16/SF
e-PUCH).
| SF E-PUCH | α e(dB) |
| 1 | 12 |
| 2 | 9 |
| 4 | 6 |
| 8 | 3 |
| 16 | 0 |
Pebase (n) and α (n) are all the parameters that define in existing standard, the object of introducing these two parameters in above-mentioned formula (1) makes the standard compliant definition of power mandate, and ISO (n) and Threshold (n) are the new arguments that the present invention introduces.
According to formula (1), as shown in Figure 2, if current time n, base station equals AGP to the authorization power of user a
a(n), and user a is according to this power emission E-PUCH, is simplified illustration, does not consider both time delay relations, and transmitting power is:
Pow_E-PUCH
a(n)＝AGP
a(n)+PL
a，A(n)+Pebase
a，A(n)+α
e(n) (2)
Antenna B receives the uplink interference Interference of user a on the time slot of E-PUCH place
b, a(n) be
Interference
B，a(n)＝Pow_E-PUCH
a(n)-PL
a，B(n) (3)
In conjunction with formula (3) and (1), can obtain
Interference
B，a(n)≤Threshold(n) (4)
From above formula, can control Interference by Threshold (n)
b, a(n).So the method that the present invention proposes can effectively be controlled the interference that space division multiplexing brings.
In the present invention, can also adjust in real time Threshold (n).On the adjacent vacant of user a point multiplex antenna (taking antenna B in Fig. 2 as example) E-PUCH place time slot, also may receive even adjacent base station user's uplink interference of other space division multiplexing users in base station, so actual interference may be larger, here { IntF is set,
b, i(n) be } the actual interference set of measurements of all E-PUCH time slots under current time n antenna B, unit is dBm, and i represents timeslot number.For the actual uplink of controlling each antenna in base station is disturbed, then an antenna uplink is set disturbs with reference to thresholding IntF
0(this thresholding is relevant with base station demodulation ability, and is empirical value), unit is dBm.In different situations, Threshold (n) is carried out to different disposal.
Situation one: in the interference value in the physical uplink channel of the enhancing dedicated channel of adjacent vacant point multiplex antenna on each time slot, maximum and uplink interference are more than or equal to default thresholding T1 (nonnegative value with reference to the difference of thresholding, for example 1dB) time, while meeting following formula, the uplink interference controlling elements in next moment are reduced to one and lower step-length.
MAX{IntF
B，i(n)}-IntF
0≥T1 (5)
Lower step-length and be more than or equal to 1 and be less than or equal in the physical uplink channel of enhancing dedicated channel of adjacent vacant point multiplex antenna maximum and uplink interference in the interference value on each time slot and, with reference to the difference of thresholding, meet formula (6).
Step_down(n)∈[1，MAX{IntF
B，i(n)}-IntF
0] (6)
Can further reduce thus Interference
b, a(n), reduce { IntF
b, i(n) }.If when Threshold (n) has reached Threshold
min, still can not meet the requirement of formula (5), stop the space division multiplexing under this antenna.
And the value of the uplink interference controlling elements in next moment is according to the value after aforesaid way adjustment and the higher value in minimum uplink interference controlling elements value, as shown in formula (7).
Threshold(n+1)＝max(Threshold
min，Threshold(n)-Step_down(n))。。。。。(7)
Situation two: in the interference value in the physical uplink channel of the enhancing dedicated channel of adjacent vacant point multiplex antenna on each time slot maximum and uplink interference with reference to the difference of thresholding be less than or equal to default thresholding T2 (non-on the occasion of, for example-1dB) time, while meeting following formula, the uplink interference controlling elements in next moment are increased to one and raise step-length.
MAX{IntF
B，i(n)}-IntF
0≤T2 (8)
Raise step-length and be more than or equal to 1 and be less than or equal to uplink interference with reference to peaked difference in the interference value on each time slot in the physical uplink channel of the enhancing dedicated channel of thresholding and described adjacent vacant point multiplex antenna, meet formula (9).
Step_up(n)∈[1，IntFx-MAX{IntF
B，i(n)}] (9)
Like this, in the situation that ensureing that uplink interference is controlled, can improve the performance number of mandate, thereby promote the transfer rate of upstream data.
And the value of the uplink interference controlling elements in next moment is according to smaller value in the value after aforesaid way adjustment and minimum uplink interference controlling elements value.When Threshold (n) has reached Threshold
max, no longer raise.As shown in formula (10).
Threshold(n+1)＝min(Threshold
max，Threshold(n)+Step_down(n))。。。。。(10)
Situation three: other situations except above-mentioned two kinds of situations, Threshold (n) does not adjust.
For the system that space division multiplexing user carries out the mandate of physical uplink channel power, the device that is included as space division multiplexing user and carries out the mandate of physical uplink channel power, this device is arranged in base station, and this device can complete the execution of said method, is no longer repeated in this description herein.

a,, to the power mandate index value of user a, send to user a by E-AGCH.Wherein, it is the method in prior art that non-NULL divides power authorization method under multiplex mode, for example, according to the UPH in SI, and SNPL, in TEBS, one or more calculation of parameter obtain the method that non-NULL divides multiplex mode authorization power.
In sum, the present invention brings the user who carries out HSUPA space division multiplexing under spaced antenna base station in the power mandate calculating of E-PUCH to the space isolation ISO between service antenna and adjacent vacant point multiplex antenna, space isolation is less, power mandate is less, and introduces uplink interference controlling elements Threshold and uplink interference with reference to thresholding IntF
0, by real-time actual interference measurement, to power, mandate is optimized adjustment, finally reaches and is rationally controlling under the prerequisite of E-PUCH place time slot uplink interference of space division multiplexing antenna, the lifting base station HSUPA higher uplink bit rate of maximum possible.
