BACKGROUND OF THE INVENTION With the increasing number of users of the Global System for Mobile communications (GSM) system communication system, the frequency of the GSM system communication system can be used to carry the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) system communication system. However, when the GSM cell and the UMTS cell center point spacing width is less than 5 MHz, mutual interference between the GSM and UMTS standard communication systems may occur. Due to the large GSM power density and frequency hopping, the interference to UMTS is disordered and bursty.

The invention is described in a clear and complete manner, and it is understood that the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention.

When the GSM system communication system and the UMTS system communication system coexist, or the GSM system communication system and the Long Term Evolution (LTE) system communication system coexist, if the coexistence of each system communication system uses a center frequency interval smaller than the standard spectrum Bandwidth can cause interference between different standard communication systems. The embodiment of the present invention can be used in the scenario where the interference between the GSM standard communication system and the UMTS standard communication system causes interference, and can also be applied to the scenario where the GSM standard communication system and the LTE standard communication system coexist to cause interference. For convenience of description, in the specific embodiment of the present invention, the coexistence of the GSM standard communication system and the UMTS standard communication system is taken as an example. It can be understood that the embodiment of the present invention is not limited to the coexistence of the communication systems of the two standards. It is also possible to coexist with any other two types of communication systems. For example, the solution is also applicable to the case where the GSM system communication system and the LTE system communication system coexist. This embodiment of the present invention does not limit this. With the method and apparatus of this embodiment, the cell traffic throughput rate can be improved.

The method and apparatus of the embodiments of the present invention may be implemented by a radio access network device, where the radio access network device includes, without limitation, any one or more of the following, such as a base station, or a base station controller, or other coordinated control device. .

The base station may be a single-system base station, for example, a base station (NodeB) in the UMTS, and may also be an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in LTE, or may be a multi-standard base station. For example, a multi-standard base station including GSM and UMTS, or a multi-standard base station including GSM and LTE, or a multi-standard base station including GSM, UMTS, and LTE.

The base station controller may be a GSM base station controller (BSC), a radio network controller (RNC) in the UMTS, or a base station controller supporting multiple standard communication systems. Other cooperative control devices may be devices that are connected to and perform cooperative control with a plurality of base stations or a plurality of base station controllers or a plurality of base stations and base station controllers.

FIG. 1 is a schematic structural diagram of a method for data scheduling according to an embodiment of the present invention. In the embodiment of the present invention, the first system communication system and the second system communication system coexist, and the bandwidth interval between the spectrum resources used by the first system communication system and the second system communication system is smaller than the standard spectrum bandwidth. The first system communication system and the second system communication system have different network standards, for example, the first system communication system is a GSM system communication system, the second system communication system is a UMTS system communication system, or the first system communication system is a GSM system. The communication system and the second system communication system are LTE system communication systems, and do not affect the implementation of the embodiment. As shown in FIG. 1, the data scheduling method may include:

Step 101: Acquire service information of at least one interference frequency point of the first standard communication system of the previous data scheduling period and the current data scheduling period.

The data scheduling period is equal to the data scheduling period of the second-standard communication system, and the second-standard communication system is the UMTS standard communication system. The data scheduling period may be a scheduling period of the HSDPA service, for example, a 2 millisecond ΤΉ.

It can be understood that the first standard communication system herein may refer to a communication system different from at least one system of the second standard communication system, and the service information for acquiring at least one interference frequency of the first standard communication system may be separately acquired. Service information of the interference frequency of each standard communication system.

The interference frequency point here is a frequency point that interferes with the second-standard communication system among the frequency hopping frequency points used when the first-standard communication system performs the service. The first standard communication system is a GSM standard communication system, and the second system is a UMTS standard communication system. For example, the standard spectrum bandwidth of the UMTS standard communication system is 5ΜΗζ, when the frequency used by the GSM standard communication system and the UMTS standard communication system are used. When the frequency interval bandwidth of the frequency point is less than 5 MHz, the GSM system communication system will cause greater interference to the UMTS standard communication system when performing services at these frequency points, that is, the first system communication system generates the second system communication system. The interference causes the data transmission of the user equipment in the second standard communication system to be interfered by the first standard communication system. Among them, the frequency used by the first standard communication system The frequency at which interference occurs in the second-standard communication system may be referred to as an interference frequency point. Since the spectrum range used by the first system communication system and the second system communication system can be preset, the interference frequency point can be determined according to the spectrum resources used by the two systems.

The service information of the interference frequency includes, without limitation, the average transmission power at the interference frequency, the duration of the transmission data at the interference frequency (also referred to as the service duration of the interference frequency), and the like, and the embodiment of the present invention is not limited thereto.

In the implementation, the service information of all the interference frequency points can be obtained, and the service information of some interference frequency points in all the interference frequency points can be obtained according to a certain rule, for example, obtaining a partial transmission frequency with a large transmission power or a long service duration. The service information of the point, or the service information of the selected N interference frequency points, where N is a positive integer greater than or equal to 1, and the value of N is set according to actual needs, and the foregoing N interference frequency points may be according to the transmission. The N interference frequency points with larger power selected by the power size. The above is only an example, and the embodiment of the present invention is not limited thereto.

Step 102: Determine, according to the previous data scheduling period acquired in step 101, the service information of the at least one interference frequency point of the first standard communication system of the current data scheduling period, the first data scheduling period and the current data scheduling period. Interference information generated by the system communication system to the first user equipment in the second system communication system.

The interference information generated by the first standard communication system on the first user equipment can be determined in various ways. For example, one of the modes may be determined by using an average transmit power of the interference frequency of the first-standard communication system and a maximum transmit power ratio of the serving cell of the first user equipment, and the following formula is taken as an example, and the embodiment of the present invention is not limited thereto.

Assuming that the current data scheduling period is the i-th data scheduling period, the previous data scheduling period is the i-1th data scheduling period, and the first-standard communication system interference information i indicates that the current data scheduling period is the first standard communication system. The interference information generated by the user equipment, ^^ indicates the ratio of the first user equipment to the signal of the first system communication system, and Se«iffi^tCe//73⁄4wer indicates the service of the first user equipment.

Step 103: The interference information generated by the first user equipment of the previous data scheduling period and the channel reported by the first user equipment received by the first user equipment according to the current data scheduling period. The quality indication CQI determines interference information generated by the second standard communication system on the first user equipment;

When the first-standard communication system and the second-standard communication system coexist, and the bandwidth interval between the spectrum resources used by the first-standard communication system and the second-standard communication system is smaller than the standard spectrum bandwidth, affecting the measurement by the first user equipment The interference information of the CQI includes interference information generated by the first standard communication system on the first user equipment and interference information generated by the second standard communication system on the first user equipment, and is received by the first user equipment due to the current data scheduling period. The reported channel quality indication CQI reflects the channel quality measurement of the first user equipment for the previous data scheduling period, and the interference information generated by the second system communication system for the first user equipment is relatively stable, so The first standard communication system of the previous data scheduling period determines the interference information generated by the first user equipment and the channel quality indicator CQI received by the first user equipment received by the current data scheduling period, and determines the second user equipment to the first user equipment. Interference information generated, for example: pilot transmit power ratio

Correction factor The interference information of the second-standard communication system indicates the interference information generated by the second-standard communication system on the first user equipment, "is a non-orthogonalization factor, which is a preset value, and the pilot transmission power ratio is the first. The ratio of the pilot transmit power of the serving cell of the user equipment to the maximum transmit power of the serving cell of the first user equipment, the pilot transmit power of the serving cell and the maximum transmit power of the serving cell may be obtained by using configuration data; Set the value, i indicates the current data scheduling period, i-1 indicates the previous data scheduling period, CQ indicates the CQI reported by the first user equipment received in the current data scheduling period, and the first system communication system interference information "represents the previous data. Interference information generated by the first-standard communication system of the scheduling period on the first user equipment.

Step 104: Determine, according to the current data scheduling period of the current data scheduling period, the interference information generated by the first user equipment, and the interference information generated by the second standard communication system obtained by the second user equipment in step 103. The CQI correction value for data scheduling.

In order to make the data scheduling of the first user equipment more accurate to the second user equipment, the CQI correction value can be determined in various ways. For example, one of the ways can be:

C3⁄4/correction value = guide difficulty ratio + correction factor,

Wherein, i represents a current data scheduling period, the interference information i of the first-standard communication system represents interference information generated by the first-standard communication system of the current data scheduling period, and the interference information of the second-standard communication system represents second Interference information generated by the system communication system to the first user equipment.

Of course, in another embodiment of the present invention, the interference information generated by the first user equipment of the current data scheduling period and the interference information generated by the second system of the first user equipment may be respectively By setting the interference factor, the CQI can be corrected more finely.

It should be noted that the foregoing is merely an example, and the embodiment of the present invention is not limited thereto.

According to the data scheduling method provided by the embodiment of the present invention, the CQI is adjusted according to the service information of the interference frequency of the first standard communication system of the previous data scheduling period and the current data scheduling period, so that the adjusted CQI correction value can be relatively accurate. Reflecting the channel quality of the current scheduling period, further The scheduling according to the adjusted CQI correction value can reduce the retransmission of HSDPA and improve the cell throughput rate. FIG. 2 is a flowchart of a method for data scheduling according to another embodiment of the present invention. In the embodiment of the present invention, the first system communication system and the second system communication system coexist, and the bandwidth interval between the spectrum resources used by the first system communication system and the second system communication system is smaller than the standard spectrum bandwidth. The first system communication system and the second system communication system have different network standards, for example, the first system communication system is a GSM system communication system, the second system communication system is a UMTS system communication system, or the first system communication system is a GSM system. The communication system and the second system communication system are LTE system communication systems, and do not affect the implementation of the embodiment. The method can be applied to a user equipment, as shown in FIG. 2, the method shown includes:

Step 201: Send, to the second standard communication system, a channel quality indicator CQI corresponding to the second standard communication system;

Step 202: Receive data transmitted by the second standard communication system, where the transmitted data is scheduled by the second standard communication system according to the CQI correction value, where the CQI correction value is determined by the second standard communication system according to the previous data. The service information of the at least one interference frequency point of the first-standard communication system of the scheduling period and the current data scheduling period obtains interference information generated by the first-standard communication system of the previous data scheduling period and the current data scheduling period on the user equipment, and Obtaining interference information generated by the second standard communication system on the user equipment according to the interference information generated by the first standard communication system of the previous data scheduling period and the CQI, further according to a current data scheduling period The interference information generated by the first-standard communication system on the user equipment and the interference information generated by the second-standard communication system on the user equipment are determined.

Using the first-standard communication system as the GSM system, The second system is UMTS as an example. Since the standard frequency bandwidth of UMTS is 5 MHz, when the frequency point used by the GSM system and the frequency interval used by the UMTS system are less than 5 MHz, the GSM standard communication system performs services at these frequencies. The UMTS system communication system causes a large interference, that is, the first system communication system interferes with the second system communication system, so that the data transmission of the user equipment in the second system communication system is interfered by the first system communication system. The frequency point of the frequency used by the first-standard communication system to interfere with the second-standard communication system may be referred to as an interference frequency point. Since the spectrum range used by the first system communication system and the second system communication system can be preset, the interference frequency point can be determined according to the spectrum resources used by the two systems.

The determination of the CQI correction value has been described in the foregoing method embodiment, and details are not described herein again. According to the data scheduling method provided by the embodiment of the present invention, the CQI is adjusted by receiving the service information of the interference frequency of the first standard communication system of the previous data scheduling period and the current data scheduling period by the radio access network side device, so that the CQI is adjusted.
