Problems solved by technology

[0005] Since the introduced E-PDCCH needs to meet the ever-changing system configuration and user configuration requirements during transmission and reception, the E-CCE (Extended-Control Channel Element) that carries it needs to maintain semi-static changes or dynamic However, the fixed E-CCE in the prior art cannot solve the transmission problem of changing available transmission resources introduced by E-PDCCH, so the transmission including E-PDCCH has the problems of low transmission efficiency and excessive transmission complexity

Abstract

An embodiment of the invention provides a control channel transmission and receiving method, a base station and user equipment, and relates to the field of communication. The control channel transmission and receiving method, the base station and the user equipment can resolve the transmission problem of changeable usable transmission resources led in by an extended-physical downlink control channel (E-PDCCH). A control channel resource configuration method includes the steps that the base station determines resource elements (REs) contained by extended-control channel elements (E-CCEs) according to system configuration and / or user configuration; the E-PDCCH is sent to the user equipment, and the E-PDCCH is borne by the E-CCEs; the user equipment receives the E-PDCCH and obtains the REs contained in the E-CCEs, and the E-PDCCH sent by the base station is received on the REs contained in the E-CCEs. The control channel transmission and receiving method, the base station and the user equipment are used for resource configuration and detection of the control channel.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a control channel transmission and reception method, a base station, and user equipment. Background technique [0002] In the downlink transmission of the Long Term Evolution (LTE for short) Rel-8 / 9 / 10 communication system, the evolved Node Base (eNB for short) sends a message for each scheduled user equipment according to the scheduling result. PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) and corresponding PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel). [0003] The PDCCH is used to transmit scheduling instruction signaling for user downlink or uplink data transmission, and the scheduling instruction signaling includes: resource allocation of data channels, modulation and coding methods, and the like. Each PDCCH is composed of 1 / 2 / 4 / 8 Control Channel Elements (Control Channel Elements, CCEs), which correspond...
