Embodiment 2

[0262] (1) Cell-level CQI correction decision module

[0263] For cell-level CQI correction, the reference is the HARQ A / N information fed back by all UEs in the cell. This correction is mainly to correct the problem affecting all UEs caused by the inaccuracy of the physical layer mapping table. Therefore, when judging whether correction is required, the MCS index value / repetition times used for each data transmission can be distinguished, and the initial transmission BLER values ​​of each MCS index value / repetition count can be counted separately, and then corrected. Specifically include:

[0264] 1. If the HARQ A / N feedback reported by the UE is received, the UE-level CQI correction amount Δ of this UE MCL_NPDSCH = 0, and is the HARQ A / N feedback of the initial transmission TB;

[0265] 2. Determine the MCS index value / number of repetitions corresponding to the initial TB transmission;

[0266] 3. Record this HARQ feedback result to the corresponding MCS index value / repe...

Abstract

Embodiments of the present invention provide a data processing method and device for a base station, the method comprising: the base station obtains HARQ information; the base station stores the NACK information in the OAM module list; the base station obtains Quantity information corresponding to the NACK information in the OAM module list; the base station obtains a NACK information proportion value according to the quantity information; the base station judges whether the NACK information proportion value is less than a preset proportion threshold; when the When the ratio of NACK information is greater than the preset ratio threshold, the base station adjusts communication quality evaluation parameters; wherein, the communication quality evaluation parameters include a minimum coupling loss MCL value; and the base station obtains scheduling information according to the adjusted MCL value; The base station communicates with the UE through the scheduling information; solves the problem of overestimation of the CQI of a specific UE in a small data volume business process, and improves data processing efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method of a base station and a data processing device of a base station. Background technique [0002] Narrow Band Internet of Things (NB-IoT, Narrow Band Internet of Things) is an important branch of low-power wide-coverage Internet of Things. NB-IoT has four major characteristics: First, wide coverage, which will provide improved indoor coverage. Under the same frequency band, NB-IoT has a gain of 20dB compared with GSM network, and 100 times larger than LTE coverage; second, strong link, with support With the ability of massive connections, one sector of NB-IoT can support 100,000 connections, and the number of terminal accesses is 50-100 times that of GSM; the third is lower power consumption, and the standby time of NB-IoT terminal modules can be as long as 10 years ; Fourth, lower terminal cost, the expected single connected module is no mo...
