Problems solved by technology

[0004] In the prior art, after the E-PDCCH is sent, the user equipment uses DMRS to perform channel estimation and demodulates the E-PDCCH. At this time, the base station needs to dynamically notify the user equipment of the DMRS antenna port number to be used through the PDCCH. However, if the E-PDCCH is carried If there is no PDCCH in the subframe, the user equipment cannot obtain the DMRS antenna port number for demodulating and receiving E-PDCCH

Abstract

The embodiment of the invention provides a control channel resource transmission method, user equipment and a base station, which relate to the field of communication and can confirm an antenna port according to corresponding parameters, so that the user equipment is enabled to correctly demodulate and receive a control channel or a control channel unit sent by the user equipment. The control channel resource transmission method comprises the following steps: acquiring configuration parameters in a candidate control channel set through the user equipment according to a preset protocol and / or a high-level signaling sent by the base station, wherein the high-level signaling is used for informing the configuration parameters; confirming the antenna port according to the acquired configuration parameters; receiving a control channel or a control channel unit sent by the base station through the antenna port; confirming the antenna port through the base station according to the configuration parameters which are the same as the user equipment; and sending the control channel or the control channel unit to the user equipment through the antenna port. The embodiment of the invention is used for control channel resource transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a control channel resource transmission method, user equipment and a base station. Background technique [0002] In the downlink transmission of the Long Term Evolution (LTE for short) Rel-8 / 9 / 10 communication system, a base station, such as an eNB (evolved Node Base, evolved base station) provides each scheduled user equipment Send a PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) and a corresponding PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel). [0003] Wherein, the PDSCH carries the data sent by the eNB to the scheduling user equipment, and the PDCCH carries the scheduling information corresponding to the PDSCH. The scheduling information includes physical channel resources allocated to the UE, MCS (Modulation and Codec Scheme, modulation and coding scheme) information used specifically, and the like. In a subframe,...
