Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] In the following embodiments of the present invention, similar to the PDCCH in the prior art, the transmission of the E-PDCCH consists of two parts, ie, a reference signal part and a data part. To solve the transmission problem of the E-PDCCH is to solve the problem of the DMRS port corresponding to the reference signal and the mapping prob...

Abstract

The present invention provides a method and a device for transmitting information on an enhanced physical downlink control channel (E-PDCCH). The sending method comprises: obtaining, according to a first aggregation level of a first candidate E-PDCCH, a first eCCE or CCE resource mapped by the first candidate E-PDCCH in a first PRB resource, in the first aggregation level, eCCE or CCE resources mapped by candidate E-PDCCHs in the first PRB resource being different, and the first PRB resource being formed of a PRB multiplexed by a candidate E-PDCCH and a PDSCH in each aggregation level of each sub-frame; determining a first DMRS port corresponding to a reference signal corresponding to the first candidate E-PDCCH; and respectively sending the reference signal corresponding to the first candidate E-PDCCH and a data part on a sub-carrier corresponding to the first DMRS port and the first eCCE or CCE resource. Technical solutions of the present invention solve an E-PDCCH transmission problem.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and equipment for transmitting information on an enhanced physical downlink control channel. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) long-term evolution (Long Term Evolution, LTE) or LTE-advanced evolution (LTE-advanced, LTE-A) system, the downlink multiple access method usually adopts orthogonal Frequency Division Multiple Access (Orthogonal Frequency Division Multiple Access, OFDMA) mode. The downlink resource of the system is divided into OFDM symbols in terms of time, and divided into subcarriers in terms of frequency. A certain subcarrier in a certain OFDM symbol is called a resource element (Resource Element, RE). In LTE version (Release) 8 / 9 / 10, a resource block (Resource Block, RB) is defined. An RB contains 12 subcarriers in the frequency domain, and a time slot in the time domain, which cont...
