Exemplary, illustrated by taking a 2*2MIMO downlink data block as an example.Assuming that 2*2MIMO is antenna a and day
Line b, antenna a and b modulation system MCS5 (EDGE (and EnhanceData rates for Global Evolution, it is enhanced
The global evolution of data transfer) code modulation mode 5).The corresponding antennas of TSC that terminal is used are antenna a.BURST
Data structure in (burst), as shown in Figure 2.MCS5 is 8PSK (Phase ShiftKeying, phase offset modulation)
Modulation system.Wherein, in 8PSK modulation system, 3 bit maps are into a symbol.There are 116 symbols on a BURST
Number, comprising 348 bits, the Tu2Zhong the superiors 0,1,47......144,145 be the sequence number that each symbol is placed on BURST,
Three layers are the corresponding bit sequences of each symbol below.Due to for one is not supported MIMO terminal, one can only be utilized
The data that individual TSC parsings antenna is sent, it is assumed that the corresponding antennas of TSC that this terminal can be used are antenna a, are, this terminal
The data of antenna a transmissions can be parsed, and this terminal can not parse the first packet of antenna b transmissions.Base station need to pass through antenna a
USF in effective data packets is sent to terminal, the USF positions in the first packet that now base station sends antenna b are determined
For the position of the first data.
103rd, corresponding first data in position to the first data described in first packet carry out reduction transmitting work(
The processing of rate, obtains the second packet.
It should be noted that in embodiments of the present invention, to the position pair of the first data described in first packet
The processing for the first data progress reduction transmission power answered refers to the position pair to the first data in the first packet after coding
The first data answered carry out the processing of reduction transmission power, wherein, first packet is the packet after coding.
Specifically, base station is behind the position of the first data in determining the first packet, by the position pair of the first data
The first data answered carry out the processing of reduction transmission power, and then obtain the second packet.Wherein, base station is by the position of the first data
Putting the method for the processing that corresponding first data carry out reduction transmission power has following several.
Mode one, base station can be set corresponding first data in the position of the first data described in first packet
For invalid data, second packet is obtained.
Wherein, the invalid data refers to that transmission power is not more than the data of the first threshold value.Further, described first
Threshold value can be 0.
Pre-set it should be noted that the first threshold value is base station, when the first threshold value is 0 milliwatt, invalid number
According to the data for referring to that transmission power is 0 milliwatt.Certainly, the first threshold value can be other values, and such as the first threshold value is 3 millis
Watt, now invalid data refers to that transmission power is not more than the data of 3 milliwatts.The present invention is not limited the occurrence of the first threshold value
System.
For example, it is assumed that 2*2MIMO is antenna a and antenna b, antenna a and b modulation system MCS5.Use USF pairs of terminal
The antenna answered is antenna a, then terminal can not parse the first packet of antenna b transmissions.Determine first that antenna b is sent in base station
Behind USF positions in packet, the corresponding data in USF positions in the first packet are set to invalid data, second is obtained
Packet.Default first threshold value in base station is 0 milliwatt, if the corresponding transmission powers of data c are 0 milliwatt, can be made data c
For invalid data, the corresponding data in USF positions in the packet that now base station can send antenna b are set to c, so that
To the second packet, as shown in Figure 3.
Mode two, base station can be carried out corresponding first data in the position of the first data described in first packet
Soft slicing processing, obtains second packet.
Wherein, soft slicing processing is to be filtered the signal that amplitude is more than certain threshold value, then uses primary signal
Subtract filtered signal and obtain one group of new signal.
It should be noted that the frequency spectrum of new signal is identical with the frequency spectrum of primary signal.
Specifically, by width in the corresponding signal of the first data described in first packet at the position of the first data
Degree is filtered processing more than the signal of the second threshold value, obtains the first signal；By the first number described in first packet
According to position at the corresponding signal of the first data and first signal subtraction, obtain secondary signal；According to the described second letter
Number, obtain second packet.
It should be noted that the second threshold value pre-sets or is configured by user interface
's.
As above described in example, the antenna b data sent are modulated into 8PSK by base station, carry out after pulse shaping, antenna b is sent
The first packet in USF positions be defined as the positions of the first data, the corresponding data in USF positions in the first packet are carried out
Soft slicing processing, so as to reduce the transmission power of the corresponding data in USF positions in the first packet, obtains the second packet.
That is, the signal that amplitude in corresponding signal at the USF positions in the first packet is more than the second threshold value is filtered
Processing, and then the first signal is obtained, as carry out corresponding letter at the USF positions in the first packet after filtering process
Number.By corresponding signal and the first signal subtraction at the USF positions in the first packet, secondary signal is obtained；As by first
Corresponding original signal is subtracted at the USF positions carried out in the first packet after filtering process at USF positions in packet
Corresponding signal, obtains corresponding secondary signal at the USF positions in the first packet.According to the secondary signal, institute is obtained
State the second packet；As, the packet of the secondary signal by corresponding signal at the USF positions in packet to obtain is determined
For the second packet.
Further, when the position of USF in the first packet being defined as into the position of the first data, base station can be by first
The corresponding data in part USF positions carry out soft slicing processing in packet, obtain second packet.
It should be noted that USF positions in part refer to that position is continuous USF in the first packet in the first packet
Put.
As above described in example, it is assumed that 2*2MIMO is antenna a and antenna b, antenna a and b modulation system MCS5.Terminal is used
The corresponding antennas of USF be antenna a, then terminal can not parse antenna b transmission the first packet.First that antenna b is sent
USF position is defined as the position of the first data in packet, and the corresponding data in part USF positions can be carried out at soft slicing
Reason, is that the continuous data in USF positions are carried out into soft slicing processing, that is to say, that by serial number 56,57,58,59 corresponding numbers
According to soft slicing processing is carried out, the second packet is obtained, as shown in Figure 4.
Mode three, base station can be by the hairs of corresponding first data in the position of the first data described in first packet
Power setting most 0 is penetrated, second packet is obtained.
Specifically, base station is determined in the first packet behind the position of the first data, the position of the first data is corresponding
The transmission power of data is set to 0, obtains the second packet, so as to not launch the position pair of the first data in the second packet
The first data answered.
104th, the effective data packets are sent by effective antenna, second number is sent by the potato masher antenna
According to bag.
Specifically, base station sends effective data packets by effective antenna, the second packet is sent by potato masher antenna,
To cause terminal to receive effective data packets by effective antenna, the second packet is received by potato masher antenna, and by having
The TSC parsing effective data packets of antenna are imitated, so that data needed for obtaining are the first valid data.Due to the second number received
Carry out reducing the processing of transmission power in base station side according to the part of the first valid data of correspondence effective data packets in bag so that
Terminal is when it is to obtain the first valid data to parse data needed for effective data packets are obtained, correspondence significant figure in the second packet
According to the interference reduction of the part of the first valid data of bag so that terminal is received after packet, more accurately parsing needs
The data of acquisition.
As above described in example, the first valid data are USF data, and base station sends effective data packets by antenna a to terminal,
Second packet is sent to terminal by antenna b.Terminal receives effective data packets by antenna a, and is received by antenna b
Two packets.Terminal obtains the USF data in effective data packets using the corresponding TSC parsings effective data packets of antenna a.Due to day
Reduction transmission power processing has been carried out at USF Data Positions in the second packet that line b is sent, so antenna b is sent
The second packet to terminal parse effective data packets obtain effective data packets in USF data interference reductions so that terminal
Receive after packet, more accurately parse the data that need to be obtained.
The embodiments of the invention provide a kind of method of data processing, the potato masher antenna of terminal and effective antenna are being determined
Afterwards, the position of the first data in potato masher antenna the first packet to be sent is determined, and it is corresponding to the position of the first data
First data carry out the processing of reduction transmission power, obtain the second packet.So, base station counts first in the first packet
According to reduction transmission power processing is carried out, the second packet is obtained；And when sending effective data packets by effective antenna, by dry
Disturb antenna and send the second packet.Because the first data in the second packet have been carried out reducing transmission power processing, institute
The interference reduction for the packet that the packet sent with potato masher antenna is sent to effective antenna so that terminal receives significant figure
After bag, the data that need to be obtained more accurately are parsed, and then realize to reduce other antenna systems to terminal acquisition number
It is believed that the interference of breath.

If the 105, the position of first data is discontinuous in first packet, by first data and institute
Other data stated in the first packet are exchanged, to cause the position of first data to connect in first packet
It is continuous.
If specifically, in the first packet, the position for the first data that base station is determined is discontinuous, then base station is by part
Corresponding first data in the position data corresponding with other positions of first data are exchanged so that in the first packet
The position of one data is continuous.
As above described in example, it is assumed that 2*2MIMO is antenna a and antenna b, antenna a and b modulation system MCS5.Terminal is used
The corresponding antennas of USF be antenna a, then terminal can not parse antenna b transmission packet.Base station will send USF by antenna a
Data are to terminal, then base station determines the potato masher antenna that antenna b is terminal, and the position of USF in the first packet is defined as into the
The position of one data.Now, if the corresponding data in USF positions are discontinuous in the packet that antenna b is sent, as antenna b is sent
Packet in the corresponding data in USF positions under different sequence numbers.With reference to shown in Fig. 2, the packet that existing antenna b is sent
Middle USF data are respectively in the data row of serial number 50,56,57,59,65.USF during base station arranges the data of serial number 50
The number that the bit number of the USF data that data, as bit number are 150 and 151 and data in the data row of serial number 56 is 170
According to, and the bit number of data is exchanged for 173 data in the data row of serial number 57 so that the data of serial number 56 and 57
Corresponding data are USF data in row.The data of USF in the data row of serial number 65, as bit number are 195 by base station
The bit number of USF data and data in the data row of serial number 59 is exchanged for 179 header data so that serial number 59
Data in data row are USF data, as shown in Figure 6.
Now, step 103 is specially：By corresponding first data in the position of the first data described in first packet
Invalid data is set to, second packet is obtained.
As above described in example, in the case where data c reflection power is not more than the first threshold value, the invalid data can be with
For c.The whole USF data of serial number 56,57 and 58 that data are arranged in the packet that base station sends antenna b are set to invalid number
According to.Optionally, the whole USF data of serial number 56,57 and 58 that data are arranged in packet antenna b sent are set to invalid number
According to c, as shown in Figure 7.
The embodiments of the invention provide a kind of method of data processing, the potato masher antenna of terminal and effective antenna are being determined
Afterwards, the position of the first data in potato masher antenna the first packet to be sent is determined, if the position of the first data is in the first number
According to discontinuous in bag, then the first data are exchanged with other data, to cause the position of the first data in the first packet
In it is continuous, and corresponding first data in position of the first data are carried out reducing the processing of transmission power, obtain the second packet.
So, the first data in the first packet are carried out reduction transmission power processing by base station, obtain the second packet；And passing through
When effective antenna sends effective data packets, the second packet is sent by potato masher antenna.Due to the first number in the second packet
According to corresponding first data in position have been carried out reducing transmission power processing, so the packet that potato masher antenna is sent is to having
Imitate the interference reduction for the packet that antenna is sent so that terminal is received after packet, more accurately parses what need to be obtained
