Abstract
Disclosed are a method and a device for sending and detecting an enhanced physical downlink control channel (E-PDCCH), relating to the field of wireless communications, and used for solving the problem of how to send downlink control information through the E-PDCCH. In the method, when a current subframe needs to send downlink control information to a terminal by adopting a frequency domain distributed transmission mode, a base station selects, according to the current aggregation level, at least one available distributed E-CCE in a distributed E-PDCCH time frequency resource area of the current subframe, and uses the selected distributed E-CCE to send the downlink control information to the terminal. The present application solves the problem of how to transmit downlink control information through the E-PDCCH.
