Detailed Description

In order to make the technical problems, technical solutions and advantageous effects solved by the embodiments of the present invention more clearly apparent, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, a flowchart illustrating a first step of a data processing method of a base station according to an embodiment of the present invention is shown, where the base station is connected to a UE, and the method specifically includes the following steps:

step 101, the base station acquires CQI information reported by UE; the base station acquires voice data;

in the embodiment of the present invention, the types of the Base stations may include a macro Base station, a micro Base station, a pico Base station, a distributed Base station, and the like, and the embodiments of the present invention do not specifically limit this, and the Base stations may mainly include a baseband processing Unit (Building Base band Unit), a Radio Remote Unit (Radio Remote Unit), and an antenna feed system;

the baseband processing unit mainly completes the functions of channel coding and decoding, modulation and demodulation of baseband signals, protocol processing and the like, and simultaneously needs to provide an interface function with an upper network element.

The remote radio unit mainly performs D/a (Digital to Analog) conversion of Digital signals, a/D (Analog to Digital) conversion of Analog signals, Digital up/down conversion and radio frequency signal modulation and demodulation on Digital/Analog signals received from/transmitted to the baseband processing unit, then performs power amplification/low noise amplification on the radio frequency Analog signals to be transmitted/received, and finally transmits the radio frequency Analog signals to the antenna feed system through the filter element for transmission. The remote radio unit needs to provide interfaces with the baseband processing unit and the antenna feed system;

the antenna feed system mainly comprises a feeder line and an antenna, and aims to centralize wireless signals received to the remote radio unit and then radiate the wireless signals out, and also centralize signals sent by user equipment and transmit the signals to the remote radio unit for processing.

Further, the base station is connected to a UE (User Equipment), and in 3G/4G systems such as LTE, the terminal is referred to as a UE. The user device may be a cell phone, tablet, laptop, or other device. The operating system of the UE may include Android (Android), IOS, Windows Phone, Windows, and the like, which is not limited in this embodiment of the present invention.

Specifically, the base station acquires CQI (Channel Quality Indicator) information reported by the UE; the CQI information is used to reflect the Channel quality of the PDSCH (Physical Downlink Shared Channel), which represents the quality of the current Channel, and the Channel quality is worse when the value is smaller, corresponding to the signal-to-noise ratio of the Channel, for example, the Channel quality of the PDSCH is represented by 0 to 15. 0 indicates the worst channel quality and 15 indicates the best channel quality.

In practical application to the embodiment of the present invention, the base station obtains the voice data, it should be noted that the voice data may include voice data that other UEs need to forward to the UE reporting the CQI information through the base station, that is, in an application scenario of the embodiment of the present invention, the base station sends data to an information transmission direction of the UE in a downlink transmission direction of the base station.

102, the base station corrects the CQI information to obtain corrected CQI information;

in a preferred embodiment of the present invention, after the base station obtains the CQI information, the base station may correct the CQI information to obtain corrected CQI information;

specifically, the base station may modify the CQI information in a manner of CQI filtering or outer loop rate control; the CQI filtering is to perform smoothing processing on CQI information according to the historical reported CQI information and the current CQI information. The outer loop rate control, i.e., outer loop link adaptation, adjusts CQI using a decoding result of ACK (Acknowledgement)/NACK (Negative Acknowledgement). Increasing the decoding result of the ACK/NACK can alleviate the measurement error of the CQI.

Step 103, the base station queries an initial Modulation and Coding Scheme (initial Modulation and Coding strategy) index value according to the corrected CQI information and a first preset mapping relation;

practically applied to the embodiment of the present invention, the configuration of the physical transmission rate in LTE (Long Term Evolution) is realized by the MCS index value. The MCS forms a rate table with the MCS index values as rows and the columns of the table as the factors that affect the communication rate concerned. Therefore, each MCS index value actually corresponds to a physical transmission rate under a set of parameters.

The base station queries an MCS index value according to the corrected CQI information and a first preset mapping relation, wherein the first preset mapping relation exists in the first mapping table, and in the uplink and downlink transmission process of the base station, if a RoHC (Robust Header Compression) function is not started, the size of a VoLTE (Voice over LTE) voice data packet is 848bits, and when the RoHC function is started, the size of the VoLTE voice data packet is 576bits, according to the size of the data packet and the communication protocol: 36.213-Table7.1.7.2.1-1: Transport block size Table (Transport block size Table) can obtain a first mapping Table (i.e. selecting a TBS parameter that is greater than and closest to or equal to the size of the data packet), where the first mapping Table includes a mapping relationship between CQI information and MCS index value, and first may map the CQI information to I _ TBS parameter through an algorithm, so as to query a corresponding MCS index value (MCS level), and further, the first mapping Table further includes a mapping relationship between MCS level and TBS (Transport block size) parameter and PRB (physical resource block) number parameter in the downlink transmission process of the base station.

For example, the maximum MCS index value may be MCS 26 in the above table, and the initial MCS index value is MCS 9, because the initial MCS index value is smaller than the maximum MCS index value, it is determined that the MCS index value corresponding to the MCS 9 is the specific MCS index value.

Step 105, the base station obtains a TBS parameter and a PRB number parameter corresponding to the specific MCS index value;

in practical application to the embodiment of the present invention, the base station obtains the TBS parameter and the PRB number parameter corresponding to the specific MCS index value, that is, the base station queries the TBS parameter and the PRB number parameter corresponding to the specific MCS index value according to the first mapping table, for example, the TBS parameter of MCS 9 is: 616 and the PRB number parameter is: 4.

and 106, the base station sends the voice data to the UE according to the TBS parameter and the PRB quantity parameter.

further, the base station acquires the maximum MCS index value, that is, the base station acquires MCS 26 in the first mapping table.

Step 205, the base station determines whether the initial MCS index value is smaller than the maximum MCS index value;

step 1, in the process of selecting the downlink MCS level of a voice user, firstly correcting the reported CQI information, wherein the CQI information correction needs to follow a slow-rising and fast-down mode;

the user is more sensitive to time delay and quality in the VoLTE service, and when the MCS upward adjustment condition is met, the user needs to slowly adjust the frequency up, so that the influence caused by the rapid change of the wireless environment is avoided; when the voice quality is poor and the MCS needs to be adjusted downwards to meet the requirements of Bler (Block Error Ratio) and the like, the MCS should be quickly adjusted downwards in large step to meet the requirements of the voice quality; adjusting uplink CQI information by adopting SINR information measured by an SRS, wherein the mode of selecting MCS is consistent with the mode of selecting downlink;

Step 3, comparing the initial MCS index value with the maximum MCS index value limited by the downlink, and selecting the MCS with a smaller value as the specific MCS index value;

step 4, taking the TBS index corresponding to the specific MCS index value and the number of PRBs as selected resources and outputting the selected resources as the resource information of the scheduling;

it should be noted that, a payload of a typical VoLTE 23.85kbps data packet is 32 bytes, a header of IPv6 is 60 bytes, a header of IPv4(Internet Protocol Version 4, fourth Version of Internet Protocol) is 40 bytes, and the current network uses IPv4 for transmission and requires to start the RoHC function. And under the condition that the RoHC header compression algorithm is started, the size of the VoLTE activation period data packet is 576bits, and under the condition that the RoHC header compression algorithm is closed, the size of the VoLTE activation period data packet is 848 bits. According to the size of the VoLTE service data packet, in combination with the existing communication protocol 36.213 tablet 7.1.7.2.1-1, the minimum value larger than 576 in the TBS parameters is 584, the series values larger than and close to 576 are selected as the TBS parameters of the downlink resource, the minimum value larger than 848 in the TBS parameters is 872, the series values larger than and close to 848 are selected as the TBS parameters of the uplink resource, and a VoLTE uplink and downlink resource occupation selection table, i.e. a first mapping table and a second mapping table, is generated according to the above parameters.

In a preferred embodiment of the present invention, when the MCS level is MCS0, the number of PRBs occupied is obviously greater than other MCS levels; when the RoHC function is turned on, the number of PRBs is 22, and when the RoHC function is turned off, the number of PRBs is 32, and in general, when MCS0 appears in a user, the user is in a situation where the radio quality is poor, even if the scheduling perception is poor, so that the general base station system considers that the MCS level is MCS0, the user is in an abnormal situation, and performs special processing or does not perform scheduling this time.
