Abstract

The invention discloses a downlink control channel detection method, a terminal and a base station. The method comprises the following steps: obtaining first auxiliary information and second auxiliaryinformation sent by the base station, wherein the first auxiliary information is used for indicating a time domain duration of a control resource set where a downlink control channel allocated by thebase station is located, and the second auxiliary information is used for indicating a resource mapping manner from a resource element group REG of the control resource set to a control channel element CCE; and performing blind detection on the downlink control channel according to the first auxiliary information and the second auxiliary information. The terminal disclosed by the invention determines a blind detection range of the downlink control channel in combination with the first auxiliary information that indicates the time domain duration of the control resource set where the downlinkcontrol channel is located and the second auxiliary information that indicates the resource mapping manner from the resource element group REG of the control resource set to the control channel element CCE, and performs the blind detection on the corresponding control resource set, in order to reduce the blind detection complexity of the downlink control channel by the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for detecting a downlink control channel, a terminal and a base station. Background technique [0002] In order to make the channel design more flexible, it is necessary for the terminal to perform blind detection on unknown control signaling. Various tentative detections are performed until the control signaling is decoded correctly. [0003] In the Long Term Evolution (LTE, Long Term Evolution) system, the Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) is used for the base station to send the downlink control instruction (DCI, Downlink Control Information), and the terminal (UE, User Equipment) except Received some system information and did not receive other information, so the UE does not know the number, size, location of the control channel element (CCE, Control Channel Element) occupied by the PDCCH, and the downlink c...
