Embodiment Construction

[0059] The following embodiments of the present invention provide a control channel transmission method, device, and equipment.

[0060] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0061] 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, the downlink multiple access method usually adopts Orthogonal Frequency Division Multiple Access Access (Orthogonal Frequency Division Multiple Access, OFDMA) mode. The downlink resources of the system are divided into Orthogonal...

Abstract

A control channel transmission method, an apparatus and a device are disclosed. The method comprises generating at least one eCCE and transmitting the control channel by the at least one eCCE. A process generating every eCCE concretely comprises determining at least two physical resource blocks PRB pairs and a plurality of enhancement resource unit sets eREG, the plurality of enhancement resource unit sets eREG are provided with incompletely-same eREG attribute information, selecting one eREG from the plurality of enhancement resource unit sets eREG, and the selected eREG is provided with different eREG attribute information and is combined an eCCE. By applying the embodiment of the invention, the eCCE is generated based on the eREG, so that the control channel is enhanced by eCCE transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method, device and equipment of a control channel. 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, the downlink multiple access method usually adopts Orthogonal Frequency Division Multiple Access Access (Orthogonal Frequency Division Multiple Access, OFDMA) mode. The downlink resources of the system are divided into Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiple, OFDM) symbols in terms of time, and are divided into subcarriers in terms of frequency. In the LTE system, a complete physical downlink control channel (Physical Downlink Control Channel, PDCCH) can be mapped to one or several control channel elements (Control Channel Element, CCE). According to LTE Release8 / 9...
