METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK CONTROL INFORMATION

摘要

Examples of the present disclosure provide a method for transmitting downlink control information to effectively support the two transmission modes of the E-PDCCH. The base station configures the localized E-PDCCH resource and the distributed E-PDCCH resource. The user terminal detects the DCI in the search space corresponding to the localized E-PDCCH resource and the search space corresponding to the distributed E-PDCCH resource, so as to obtain the downlink control information transmitted by the base station.

主权项

1. A method for transmitting downlink control information, comprising:
configuring, by a base station, for a user terminal at least one of a localized enhanced physical downlink control channel (E-PDCCH) resource and a distributed E-PDCCH resource used for transmitting downlink control information; transmitting, by the base station, the downlink control information to the user terminal via the at least one of the localized E-PDCCH resource and the distributed E-PDCCH resource, such that the user terminal detects the downlink control information via a blind detection manner on the at least one of the localized E-PDCCH resource and the distributed E-PDCCH resource; wherein the localized E-PDCCH resource comprises resource elements which are continuous in a frequency domain, and the distributed E-PDCCH resource comprises resource elements which are discontinuous in the frequency domain.
