 Embodiment 1

 FIG. 1 is a flowchart of a data sending method according to Embodiment 1 of the present invention. The method of this embodiment is applicable to the case where two terminal devices in a wireless network transmit data to a base station on the same frequency simultaneous slot. The method can be performed by a first terminal device, which is usually implemented in hardware and software, and can be integrated in a memory of the first terminal device, for example integrated in a processor chip, for execution by a processor. The method of this embodiment includes the following steps:

 S110. The first terminal device receives a first rotation indication sent by the base station.

Generally, the data in the GERAN is transmitted, and the first terminal device that sends the data needs to receive the rotation indication sent by the base station to perform the angle rotation processing on the data to be sent before the first terminal device that sends the data is processed, and the second rotation instruction is not received. The terminal device does not need to perform angular rotation processing on the data to be sent. Generally, in the embodiment, the first terminal device performs angular rotation processing on the data to be sent, after receiving the first rotation indication sent by the base station, performing angle rotation using the first angle, and correspondingly, after receiving the data, the base station also receives The angle rotation processing may be performed by using the first angle. Therefore, the first terminal device performs angular rotation processing on the data symbols to be sent to the base station, and is based on the first rotation indication notified by the base station, so that the first terminal device can be configured according to With the base station The data to be sent to the base station should be angularly rotated by the angle rotation method to ensure the reliability of the angle rotation processing.

 S120, the first terminal device performs angular rotation processing on the data symbols to be sent to the base station by using a first angle according to the first rotation indication, to generate a first angle rotation data symbol;

 In the known GERAN, the data transmitted between the terminal device and the base station can be expressed in a plural form, that is, the data can be represented by the amplitude and the angle. Generally, the data in the GERAN is transmitted, and the data sent on the same frequency gap is different. In the transmission channel, different transmission channels will introduce different angular rotations, resulting in the same angle of data at the transmitting end passing through different channels, which will have an angle at the receiving end. When the angle between the received data is 90 degrees, that is, when the data is orthogonal, the co-channel interference is the smallest. However, the transmission channels in the actual situation are often not orthogonal. Therefore, the first terminal device performs angular rotation processing on the data symbols to be sent to the base station according to the received first rotation indication, so that the angle of the data symbols changes, and the generated The first data symbol is equal in amplitude to the original data symbol, and the angle is different; because the angle of the data symbol sent by the first terminal device changes, the angle between the data also changes, and the channel can be statistically brought after For better orthogonality, the first terminal device controls the angular rotation of the data symbols to be transmitted so that the angle between the data is as close as possible or orthogonal. In a specific implementation, the first terminal device may perform angular rotation processing on the first data symbol by using the first angle according to the first rotation indication sent by the base station, and correspondingly, the base station also receives the first angle according to the first rotation indication. The first modulated data symbol sent by the first terminal device is subjected to an angular rotation process to generate a first angular rotation data symbol.

 It should be noted that, in this embodiment, before the first terminal device performs the angle rotation processing on the first data symbol, the first data symbol needs to be processed normally. For example, the first terminal device may process the angle to be processed by using differential coding. The rotated first data symbol, the present invention does not limit the manner in which the first data symbol is processed prior to angular rotation.

 S130. The first terminal device performs modulation processing on the first angular rotation data symbol to generate a first modulated data symbol.

In the GERAN, before the terminal device transmits data, the data to be transmitted needs to be modulated. Therefore, the first terminal device performs modulation processing on the first angle rotated data symbol data that has undergone the angular rotation processing, and generates a packet to be transmitted to the base station. A modulated data symbol. Modulation processing in the GERAN, for example, Gaussian filtering minimum frequency shift keying based on the GSM system (Gaussian Filtered Minimum Shift Keying, abbreviated as: GMSK) modulation, GSMK modulated data spectrum is compact, and error characteristics are good.

 S140, the first terminal device sends the first modulated data symbol to the base station on a physical resource, so that the first modulation sent by the base station to the first terminal device on the physical resource The data symbol and the second modulated data symbol transmitted by the second terminal device on the physical resource are demodulated.

 The first terminal device sends the first modulated data symbol to the base station on the physical resource, where the physical resource refers to the time domain and the frequency domain of the data transmission, and the first terminal device and the second terminal device respectively send the GMSK modulated to the base station. Data, and the base station receives the first modulated data symbol sent by the first terminal device and the second modulated data symbol sent by the second terminal device on the same physical resource, that is, on the same time slot and the same frequency, The base station is caused to demodulate the received data.

 When the base station needs to simultaneously demodulate and acquire the data transmitted by the first terminal device and the data transmitted by the second terminal device for the received first modulated data symbol and the second modulated data symbol, a joint demodulation manner may be employed. The joint demodulation is a data separation method. The base station can use, for example, a data separation method to demodulate a plurality of data received on the same frequency at the same time slot, and obtain data transmitted by the first terminal device and data transmitted by the second terminal device.

 It should be noted that, in the foregoing embodiment, the number of the second terminal devices may be one, two or more, which is not limited in this embodiment.

 In the data sending method provided by the embodiment, the first terminal device may perform angular rotation processing on the data to be sent to the base station, and change the angle between the data sent by the second terminal device and the same frequency in the same time slot by the angle rotation. The angle between the data sent by the first terminal device transmitted on the channel and the data sent by the second terminal device is changed, and the data sent by the first terminal device and the data sent by the second terminal device are statistically obtained by probability statistics. The orthogonality between the two is better, so that the interference between the data transmitted on the same frequency simultaneous slot can be reduced to some extent, thereby improving the performance of the received signal of the base station.

In a specific implementation, the first angle may be carried in the first rotation indication, or may be preset in the first terminal device. Specifically, the first terminal device may preset a first angle in advance, and after receiving the first rotation indication sent by the base station, perform angle rotation processing on the first data symbol by using the first angle set before, and the preset The first angle is pre-agreed by the first terminal device and the base station; for example, the first terminal device pair is pre-defined to have certain training sequences (Training Sequence, referred to as: TSC) data, after the normal data processing, the data needs to be rotated according to the preset angle rotation rule. The data with other TSCs can be rotated without angle. The first terminal device can The first rotation is performed on the data with different TSCs according to different rules according to the type of the TSC. The first rotation is also included in the first rotation indication sent by the base station, so that the first terminal device receives the data according to the reception. The first angle included in the first rotation indication is subjected to angular rotation processing on the first data symbol by using the first angle sent by the base station before transmitting the data.

 Further, when the foregoing embodiment 120 is specifically implemented, the first terminal device may perform angular rotation processing on each symbol in the burst BURST of the first data symbol by using the first angle.

 In GERAN, the data symbol sent by the first terminal device to the base station is specifically a string of data.

(BURST), a BURST contains 156.25 symbols, each symbol is a complex number, and a complex triangle can be used to represent a symbol: z=r (cose+isine) , vector 0Z is the symbol in the complex plane Vector expression, where r is the modulus of the complex number, that is, the amplitude of the symbol, Θ is the beginning of the X-axis in the complex plane, and the angle of the end of the vector 0Z is called the argument of the complex number, that is, the The angle of the symbol. The data transmitting method provided in this embodiment specifically describes the form of the data symbols transmitted by the first terminal device, and performs the angular rotation processing on each symbol included in a BURST.

 Specifically, in the above embodiment, when the first terminal device performs angular rotation on the data symbol, the first terminal device performs angular rotation processing according to the first angle sent by the base station or preset by the first terminal, and therefore, the base station rotates at an angle. It is also known that the rotation angle of the first angle rotation data symbol after the angular rotation processing, that is, the first angle, can be subjected to the angular rotation processing of the data symbol, and the direction of the rotation is not limited to the clockwise direction or the inverse direction. The hour hand direction, or other rotation mode; for example, the first terminal device receives the first rotation direction sent by the base station, and the first angle included in the first rotation instruction is specifically 30°, and the data to be sent to the base station is rotated at an angle of 30°. Processing, when the base station performs the angular rotation processing on the data symbols sent by the first terminal device, it may be rotated by 30° in the reverse direction or 330° in the same direction, as long as the data symbol can be restored to the first terminal device. The angle before the angle rotation process can be.

Optionally, in S140, the second modulation symbol may be generated by the second terminal device directly performing modulation processing on the second data symbol. In a specific implementation, the second terminal device may also adopt the second rotation indication sent by the base station. The second angle performs an angular rotation process on the second data symbol, and accordingly, The second modulated data symbol may also be: the second terminal device performs angle rotation processing on the second data symbol by using the second angle according to the second rotation indication sent by the base station to generate a second angle rotation data symbol, and rotates the second angle Data symbols are generated by modulation processing.

 It should be noted that the first angle used by the first terminal device to perform angular rotation processing on the first data symbol and the second angle used by the second terminal device to perform angular rotation processing on the second data symbol are different, that is, The angles of rotation when the first terminal device and the second terminal device both need to perform angular rotation processing on the data symbols to be transmitted to the base station are different.

 In the data sending method provided by the embodiment, the first terminal device may perform angular rotation processing on the data to be sent to the base station, and change the angle between the data sent by the second terminal device and the same frequency in the same time slot by the angle rotation. The angle between the data sent by the first terminal device transmitted on the channel and the data sent by the second terminal device is changed, and the data sent by the first terminal device and the data sent by the second terminal device are statistically obtained by probability statistics. The orthogonality between the two is better, so that the interference between the data transmitted on the same frequency simultaneous slot can be reduced to some extent, thereby improving the performance of the received signal of the base station. In addition, for the second terminal device, it may also perform angular rotation according to the angle rotation indication notified by the base station, so that the interference between the data transmitted by the first terminal device and the data sent by the second terminal is small.
