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-ControlChannelElement, extended channel control element) carrying it needs to maintain semi-static changes or dynamic changes. 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

Embodiments of the present invention provide a control channel transmission and reception method, base station and user equipment, which relate to the communication field and can solve the transmission problem of changing available transmission resources introduced by E-PDCCH. A method for configuring control channel resources, comprising: a base station determines resource elements RE contained in an extended control channel element E-CCE according to system configuration and / or user configuration; and sends an extended physical downlink control channel E-PDCCH to user equipment, the The E-PDCCH is carried by the E-CCE; the user equipment receives the E-PDCCH, obtains the RE included in the E-CCE, and receives the E-PDCCH sent by the base station on the RE included in the E-CCE. The embodiment of the present invention is used for resource configuration and detection of a control channel.

Description

technical field [0001] The present invention relates to the communication field, 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 base station (evolvedNodeBase, eNB for short) sends a PDSCH (PhysicalDownlinkSharedChannel, PhysicalDownlinkSharedChannel, Physical Downlink Shared Channel) and the corresponding PDCCH (PhysicalDownlinkControlChannel, Physical Downlink Control Channel). [0003] Wherein, the PDCCH is used to transmit scheduling instruction signaling for user downlink or uplink data transmission, and the scheduling instruction signaling includes: data channel resource allocation, modulation and coding methods, and the like. Each PDCCH is composed of 1 / 2 / 4 / 8 control channel elements (ControlChannelElement, CCE), corresponding to different code rates, and each CCE i...
