Description

 Method and base station for data processing

 The present invention relates to the field of communications, and in particular, to a data processing method and a base station. Background technique

 MIMO (Mul t iple-In ut Mul t iple-Out-put) is a structure in which multiple antenna transmissions and multiple antenna receptions are performed. Multiple antennas at the transmitting end can be used to independently transmit signals, and at the receiving end, multiple antennas can be used to receive and restore the original information. MIMO can dramatically increase system throughput and transmission distance without increasing bandwidth or total transmit power.

 Assignment in GERAN (GSM (Global System for Mobile Communications) / EDGE (Enhanced Data Rates for Global Evolution) Radio Access Network, GSM/EDGE wireless communication network) In the phase, the base station allocates the USF (Uplink State Flag) to the terminal, so that after the base station sends the data, the terminal receives the data for decoding, and when the USF information is parsed, the parsed USF information and the allocated The USF information is compared. If they are consistent, the terminal sends data in the next uplink block.

In the process of implementing the above MIMO receiving or transmitting data, the inventors have found that at least the following problems exist in the prior art: The base station can use MIMO to schedule different users on the same time frequency using multiple antennas. However, for a terminal that does not support the MIMO function, the received data can only be parsed by one TSC, and the USF information of the received data is obtained. Since each antenna has different TSC (Training Sequence Code, 1|Eastern sequence 歹'J) and is orthogonal to each other, therefore, when a terminal that does not support the MIMO function parses the received data using the TSC of one antenna system, The data on other antenna systems will form co-channel interference, which will interfere with the USF information of the terminal that does not support the MIMO function.

 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 An embodiment of the present invention provides a data processing method, as shown in FIG. 1 , including:

101. Determine an effective antenna and an interference antenna of the terminal.

The effective antenna refers to a TSC allocated by the base station to the terminal. Sequence Code, the corresponding antenna. The interference antenna refers to an antenna other than the effective antenna in the base station.

 Specifically, the base station allocates a TSC to the terminal. Since one antenna corresponds to one TSC, the base station can determine the effective antenna and the antenna of the terminal. The terminal can synchronize, estimate the channel, etc. through the TSC.

 It should be noted that the method for the base station to allocate the TSC to the terminal is the same as that in the prior art, and details are not described herein again.

 It should be noted that the terminal in the embodiment of the present invention may support the MIM0 function or the MIM0 function, which is not limited by the present invention.

 For a terminal that does not support the MIM0 function, the terminal can determine that the terminal can only use one TSC to parse the data. Therefore, the base station can determine that there is only one effective antenna corresponding to the terminal, that is, the antenna corresponding to the TSC allocated by the base station to the terminal.

 For a terminal that supports the MIM0 function, the terminal can parse the data through at least one TSC. Therefore, the base station can determine at least one TSC corresponding antenna of the terminal as a valid antenna.

 102. Determine a location of the first data in the first data packet.

 The first data packet refers to a data packet that is sent by the interference antenna and transmitted simultaneously with a valid data packet on the effective antenna. The location of the first data includes a location corresponding to a location of the first valid data in the valid data packet. The valid data packet refers to a data packet that is sent to the terminal through the effective antenna.

 It should be noted that the location of the first data may only include a location corresponding to the location of the first valid data in the valid data packet, where the location of the first data and the location of the first valid data in the valid data packet the same. The location of the first data may also include locations other than the location corresponding to the location of the first valid data in the valid data packet.

For example, if the location of the first valid data in the valid data packet is, the location of the first data of the first data packet may be determined to be a location corresponding to the location 55, 56, 57 of the first valid data in the valid data packet, if Also 55, 56, 57. It is also possible to determine that the location of the first data is a bit corresponding to the location 55, 56, 57 of the first valid data in the valid data packet. In addition to 55, 56, 57, it also includes a position adjacent to both sides, namely 54 and 58. At this time, the position of the first data is the position of 54, 55, 56, 57, 58 in the first data packet.

 It should be noted that, the location of the first data includes, in addition to the location corresponding to the location of the first valid data in the valid data packet, and includes other locations adjacent to each other, specifically including adjacent ones. The position may be determined according to the accuracy of obtaining the first valid data, which is not limited by the present invention.

 The first valid data may include an USF (Uplink State Flag) in the valid data packet, that is, for example, the location of the USF in the first data packet and the USF of the valid data packet. In the case where the locations are consistent, the base station may determine the USF location in the first data packet as the location of the first data. It is also possible to determine the USF location in the first packet and the location adjacent to the USF location as the location of the first data.

 In this case, the first valid data may include a data header (header) adjacent to the USF in the valid data packet, or a data adjacent to the USF in the valid data packet, in addition to the USF in the valid data packet. The ( data ) part is not limited here.

 Exemplarily, a downlink data block of 2*2MIM0 is taken as an example for description. 2*2MIM0 is the modulation mode of antenna a and antenna b, antennas a and b. MCS5 (EDGE (Enhanced Data Rates for Global Evolution) coding modulation method 5). The antenna corresponding to the TSC used by the terminal is antenna a. The data structure in BURST (burst), as shown in Figure 2. The MCS5 is a modulation method of 8PSK (Phase Shift Keying). Among them, in the 8PSK modulation scheme, 3 bits are mapped into one symbol. There are 116 symbols on a BURST, including 348 bits, and the top 0, 1, 47, 144 in Figure 2,

145 is the serial number of each symbol placed on the BURST, and the lower three layers are the bit numbers corresponding to each symbol. For a terminal that does not support MIM0, only one TSC can be used to analyze the data transmitted by the antenna. It is assumed that the antenna corresponding to the TSC that the terminal can use is the antenna a, that is, the terminal can parse the data sent by the antenna a, and This terminal cannot parse the first packet sent by antenna b. The base station needs to send the USF in the valid data packet to the terminal through the antenna a, and the base station sends the USF in the first data packet sent by the antenna b. The location is determined as the location of the first data.

 1 0. Perform a process of reducing transmit power on the first data corresponding to the location of the first data in the first data packet, to obtain a second data packet.

 It should be noted that, in the embodiment of the present invention, the process of reducing the transmit power of the first data corresponding to the location of the first data in the first data packet refers to the first data packet in the first data packet. The first data corresponding to the location of the data performs a process of reducing the transmit power, wherein the first data packet is an encoded data packet.

 Specifically, after determining the location of the first data in the first data packet, the base station performs a process of reducing the transmit power by using the first data corresponding to the location of the first data, to obtain a second data packet. The method for the base station to reduce the transmission power by using the first data corresponding to the location of the first data is as follows.

 Manner 1: The base station may set the first data corresponding to the location of the first data in the first data packet as invalid data, to obtain the second data packet.

 The invalid data refers to data whose transmit power is not greater than the first threshold. Further, the first threshold value may be 0.

 It should be noted that the first threshold is preset by the base station. When the first threshold is 0 milliwatts, the invalid data refers to data with a transmission power of 0 milliwatts. Of course, the first threshold value may be other values, for example, the first threshold value is 3 milliwatts, and the invalid data at this time refers to data whose transmission power is not more than 3 milliwatts. The present invention does not limit the specific value of the first threshold value.

 For example, 4 2 2 * 2M I M0 is antenna a and antenna b, and antennas a and b are modulated by MC S 5. The antenna corresponding to the US F used by the terminal is the antenna a, and the terminal cannot parse the first data packet sent by the antenna b. After determining the U S F position in the first data packet sent by the antenna b, the base station sets the data corresponding to the U S F position in the first data packet as invalid data to obtain the second data packet. The first threshold preset by the base station is 0 milliwatts. If the transmit power corresponding to the data c is 0 milliwatts, the data c can be regarded as invalid data, and the base station can use the U SF in the data packet sent by the antenna b. The data corresponding to the location is set to c, so that the second data packet is obtained, as shown in FIG.

Manner 2: The base station may set a location of the first data in the first data packet. The first data to be processed is subjected to soft clipping processing to obtain the second data packet.

 The soft clipping process filters the signal whose amplitude is greater than a certain threshold, and then subtracts the filtered signal from the original signal to obtain a new set of signals.

 It should be noted that the spectrum of the new signal is the same as the spectrum of the original signal.

 Specifically, the signal corresponding to the second threshold value in the signal corresponding to the first data at the location of the first data in the first data packet is filtered to obtain a first signal; A signal corresponding to the first data at the location of the first data in the data packet is subtracted from the first signal to obtain a second signal. According to the second signal, the second data packet is obtained.

 It should be noted that the second threshold value may be preset or may be set through a user interface.

 As described in the above example, the base station modulates the data transmitted by the antenna b into 8PSK, and after performing pulse shaping, determines the USF position in the first data packet sent by the antenna b as the position of the first data, and corresponds the USF position in the first data packet. The data is subjected to soft clipping processing, thereby reducing the transmission power of the data corresponding to the USF position in the first data packet, and obtaining the second data packet. That is, the signal corresponding to the second threshold value in the corresponding signal at the USF position in the first data packet is filtered, and then the first signal is obtained, that is, the first data packet after the filtering process is performed. The corresponding signal at the USF position. Subtracting the corresponding signal at the USF position in the first data packet with the first signal to obtain a second signal; that is, subtracting the original signal corresponding to the USF position in the first data packet and performing filtering processing A corresponding signal at the USF position in a data packet obtains a second signal corresponding to the USF position in the first data packet. And obtaining, according to the second signal, the second data packet; that is, determining, by using the second signal in the data packet, the data packet corresponding to the acquired second signal as the second data packet.

 Further, when determining the location of the USF in the first data packet as the location of the first data, the base station may perform soft clipping processing on the data corresponding to the partial location of the first data packet to obtain the second data packet.

It should be noted that a part of the USF location in the first data packet refers to a USF location that is consecutive in the first data packet. As described in the above example, 4*2MIM0 is the antenna a and the antenna b, and the modulation modes MCS5 of the antennas a and b. If the antenna corresponding to the USF used by the terminal is the antenna a, the terminal cannot parse the first data packet sent by the antenna b. Determining the position of the USF in the first data packet sent by the antenna b as the position of the first data, and performing soft clipping processing on the data corresponding to the part of the USF, that is, performing soft clipping processing on the data in which the USF position is continuous. That is to say, the data corresponding to the numbers 56, 57, 58, and 59 are subjected to soft clipping processing to obtain a second data packet, as shown in FIG.

 Manner 3: The base station may set a transmit power of the first data corresponding to the location of the first data in the first data packet to 0, to obtain the second data packet.

 Specifically, after determining the location of the first data in the first data packet, the base station sets the transmit power of the data corresponding to the location of the first data to 0, to obtain the second data packet, so that the second data packet may not be transmitted. The first data corresponding to the location of a data.

 104. Send the valid data packet by using the effective antenna, and send the second data packet by using the interference antenna.

 Specifically, the base station sends the valid data packet through the effective antenna, and sends the second data packet through the interference antenna, so that the terminal receives the valid data packet through the effective antenna, receives the second data packet through the interference antenna, and passes the effective antenna. The TSC parses the valid data packet, so that the required data is obtained as the first valid data. The part of the received second data packet corresponding to the first valid data of the valid data packet is processed by the base station side to reduce the transmission power, so that the terminal obtains the required data when parsing the valid data packet to obtain the first valid data. The interference of the portion of the second data packet corresponding to the first valid data of the valid data packet is reduced, so that the terminal can more accurately parse the data to be acquired after receiving the data packet.

As described in the above example, the first valid data is USF data, and the base station transmits a valid data packet to the terminal through the antenna a, and transmits the second data packet to the terminal through the antenna b. The terminal receives the valid data packet through the antenna a, and receives the second data packet through the antenna b. The terminal uses the TSC corresponding to the antenna a to parse the valid data packet to obtain the USF data in the valid data packet. Since the reduced transmit power processing has been performed at the USF data location in the second data packet transmitted by the antenna b, the second data packet sent by the antenna b is effective for terminal resolution. The interference of the USF data in the data packet obtaining valid data packet is reduced, so that the terminal can more accurately parse the data to be acquired after receiving the data packet.

 An embodiment of the present invention provides a data processing method, after determining an interference antenna and an effective antenna of a terminal, determining a location of the first data in the first data packet to be transmitted by the interference antenna, and determining a location of the first data. The corresponding first data performs a process of reducing the transmission power to obtain a second data packet. In this way, the base station performs the reduced transmit power processing on the first data in the first data packet to obtain the second data packet; and transmits the second data packet through the interference antenna when transmitting the valid data packet through the effective antenna. Since the first data in the second data packet has been reduced in transmission power processing, interference of the data packet transmitted by the interference antenna to the data packet transmitted by the effective antenna is reduced, so that the terminal is more accurate after receiving the valid data packet. The data to be obtained is parsed, and the interference of other antenna systems to obtain data information of the terminal is implemented.

 Further, if, in step 103, the base station performs the method for reducing the transmit power processing on the first data corresponding to the location of the first data in the first data packet, the base station sends the first data packet into the first data packet. The first data corresponding to the location of the first data is set to be invalid data, and the second data packet is obtained. Before step 103, as shown in FIG. 5, the method further includes:

 105. If the location of the first data is discontinuous in the first data packet, the first data is exchanged with other data in the first data packet, so that the first data is The location is continuous in the first data packet.

 Specifically, if the location of the first data determined by the base station is not continuous in the first data packet, the base station exchanges the first data corresponding to the location of the part of the first data with the data corresponding to the other location, so that the first data is used. The position of the first data in the packet is continuous.

As described in the above example, 4*2MIM0 is the antenna a and the antenna b, and the modulation modes MCS5 of the antennas a and b. If the antenna corresponding to the USF used by the terminal is the antenna a, the terminal cannot parse the data packet sent by the antenna b. The base station will transmit the USF data to the terminal through the antenna a, and then the base station determines that the antenna b is the interference antenna of the terminal, and determines the location of the USF in the first data packet as the location of the first data. At this time, if the data corresponding to the USF position in the data packet sent by the antenna b is discontinuous, that is, the USF position in the data packet sent by the antenna b corresponds. The data is under different serial numbers. Referring to FIG. 2, the data of the USF in the data packet transmitted by the existing antenna b is respectively in the data column of sequence numbers 50, 56, 57, 59, 65. The base station will use the data of the USF in the data column of sequence number 50, that is, the data of the USF data of the bit number 150 and 151 and the data of the data column of the sequence number of 56, and the data of the data column of the sequence number 57. The data of the bit number 173 is exchanged, so that the corresponding data in the data columns of the numbers 56 and 57 are USF data. The base station exchanges the data of the USF in the data column with the sequence number of 65, that is, the USF data with the bit number 195 and the data with the bit number 179 of the data sequence with the sequence number of 59, so that the data column with the sequence number of 59 The data in the data is USF data, as shown in Figure 6.

 At this time, the step 103 is specifically: setting the first data corresponding to the location of the first data in the first data packet as invalid data, to obtain the second data packet.

 As described in the above example, in the case where the reflected power of the data c is not greater than the first threshold, the invalid data may be c. The base station sets all the USF data of the data column in the data packet sent by the antenna b to 56, 57 and 58 as invalid data. Optionally, the number of the data columns in the data packet sent by the antenna b is 56, 57, and 58. All USF data is set to invalid data c, as shown in FIG. 7.

 An embodiment of the present invention provides a data processing method, after determining an interference antenna and an effective antenna of a terminal, determining a location of the first data in the first data packet to be transmitted by the interference antenna, if the location of the first data is If the first data packet is discontinuous, the first data is exchanged with other data, so that the location of the first data is continuous in the first data packet, and the first data corresponding to the location of the first data is reduced in transmit power. Processing, get the second data packet. In this way, the base station performs the reduced transmit power processing on the first data in the first data packet to obtain the second data packet; and when the valid data packet is sent through the effective antenna, the second data packet is sent through the interference antenna. Since the first data corresponding to the location of the first data in the second data packet has been reduced in transmission power processing, interference of the data packet transmitted by the interference antenna to the data packet sent by the effective antenna is reduced, so that the terminal receives After the data packet, the data to be acquired is parsed more accurately, and the interference of other antenna systems to obtain data information of the terminal is implemented.
