Abstract

The invention disclosed a method of transmission control information, base stations and user equipment.This method includes: according to the enhancement of the feature parameter to generate DCI. Among them, when the coverage enhanced feature parameter is not greater than the predetermined threshold, the DCI includes the narrow band position indicator information, or when the coverage enhanced feature parameters are greater than the predetermined threshold, it should beDCI does not include the narrow -band position indicator information, the enhanced enhanced character parameters include the number of repetitions required by the cover or the enhancement of the coverage; the DCI is sent to the UE through the control channel, so that the UE includes the narrow belt location indicator information in the DCI in the DCI in the DCI.Determine the position of the UE's narrow band according to the narrow -band location indicator information, or, in the DCI does not include the narrow band position indicator information in the DCI, determine the position of the narrowband of the UE according to the scheduled narrow belt location information.The method of transmission control information of the embodiment of the present invention, base stations and user equipment can improve the flexibility of scheduling.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a method for transmitting control information, a base station and user equipment. Background technique [0002] In a Long Term Evolution (LTE) system, data transmission needs to occupy certain resources in the time-frequency domain. In the time domain, it refers to which time or which subframe to send; in the frequency domain, resources refer to which subcarrier to send. Generally speaking, a physical layer data channel for sending data such as a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) / physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) is controlled by a corresponding physical layer control channel, that is, a physical downlink control channel ( Physical Downlink Control Channel, PDCCH) / Enhanced Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, EPDCCH) scheduling, multiplexed in the sam...
