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 invention provides a method and equipment for transmitting information on an enhanced physical downlink control channel. The sending method comprises the following steps that: according to a first aggregation grade, which first alternative E-PDCCHs belong to, first eCCE or CCE resources mapped by the first alternative E-PDCCHs in a first PRB resource are obtained; the eCCE or CCE resources mapped by various alternative E-PDCCHs in the first aggregation grade in the first PRB resource are different from each other; the first PRB resource is composed of PRBs multiplexed by the alternative E-PDCCHs and PDSCHs in various aggregation grades in various sub-frames; a first DMRS port corresponding to a reference signal corresponding to the first alternative E-PDCCHs is determined; and a reference signal and a data part corresponding to the first alternative E-PDCCHs are sent on sub-carriers and the first eCCE or CCE resources corresponding to the first DMRS port respectively. By means of the technical scheme provided in the invention, the E-PDCCH transmission problem is solved.

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 an 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, resource blocks (Resource Block, RB) are defined. One RB contains 12 subcarriers in the frequency domain, and one time slot in the time domain, that...
