Problems solved by technology

[0003] However, in the actual large-scale network, limited by the network conditions, there may be an increase in the load of the primary cell due to excessive pre-scheduling, thereby affecting the Physical Downlink Control Channel (PDCCH) of the adjacent cell. It causes severe interference with the Physical Uplink Shared Channel (PUSCH), which leads to high utilization of PDCCH in the entire network and reduced throughput of edge users.

Abstract

The embodiment of the invention provides a self-adaptive pre-scheduling method and device. The method comprises the following steps: receiving first overload interference indication information sent by at least one neighbor cell base station; And adjusting the pre-scheduling mode of the main cell according to the interference noise level indicated by the first overload interference indication information. According to the embodiment of the invention, first overload interference indication information sent by at least one neighbor cell base station is received through a main cell; wherein the first overload interference indication information is used for indicating an interference noise level on a resource block corresponding to the adjacent cell; the main cell judges the interference noiselevel indicated by the first overload interference indication information; The pre-scheduling mode of the main cell is adjusted, the flexibility of the pre-scheduling mode of the main cell is improved, the situation that the load of the main cell is increased due to too many pre-scheduling degrees can be avoided, serious interference caused by the main cell to adjacent cells is avoided, the PDCCHutilization rate of the whole network is reduced, and the throughput of edge users is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an adaptive pre-scheduling method and device. Background technique [0002] In a Long Term Evolution (LTE for short) system, in order to shorten the transmission delay of uplink data, the base station usually uses a pre-scheduling method to make the terminal equipment send uplink data. In the prior art, pre-scheduling includes fixed-interval pre-scheduling and pre-scheduling based on downlink data packets. [0003] However, in the actual large-scale network, limited by the network conditions, there may be an increase in the load of the primary cell due to excessive pre-scheduling, thereby affecting the Physical Downlink Control Channel (PDCCH) of the adjacent cell. It causes serious interference with the Physical Uplink Shared Channel (PUSCH for short), which leads to an excessively high utilization rate of the PDCCH in the entire network and ...
