Abstract

Embodiments of this application provide a control channel transmission method and apparatus. In the embodiments of this application, a control channel is mapped to an eREG, which corresponds to determined eREG information, among a designated number of eREGs in each unit physical resource block, where each eREG among the designated number of the eREGs is formed by a designated number of resource elements, the designated number of the resource elements are selected from corresponding resource elements at an S th position in each group, and S is a positive integer smaller than or equal to N, so that the control channel can be transmitted on the mapped eREG.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a control channel transmission method and device. Background technique [0002] In a wireless communication system such as a Long Term Evolution (LTE) system or an Advanced Long Term Evolution (Long Term Evolution Advanced, LTE-Advanced) system, a Physical Downlink Control Channel (Physical Downlink Control Channel) based on precoding transmission is introduced. , PDCCH), that is, an enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, ePDCCH). The ePDCCH enables a user equipment (User Equipment, UE) to perform demodulation based on a specific reference signal, that is, a demodulation reference signal (Demodulation Reference Signal, DMRS). The ePDCCH is transmitted in the area where the downlink data channel is transmitted in a subframe, and can be frequency-divided with a physical downlink shared channel (Physical Downlink Shared Cha...
