Embodiment 1

[0090] figure 2 This is a schematic flow chart of a control channel detection method provided in the first embodiment of the present disclosure, such as figure 2 As shown, the first embodiment provides a control channel detection method, which is applied to a transmitting end (terminal), and the method includes:

[0091] Step S101: Report the indication information of beam recovery.

[0092] Specifically, the transmitting end (terminal) monitors the beam. The monitoring process is mainly to judge the beam failure (beam failure) based on the reference signal. If beam recovery is required, the transmitting end (terminal) will report for beam recovery For example, the instruction information may be the instruction information of the transmitting end (terminal), beam instruction information, etc.

[0093] Step S102: After reporting the indication information, detect M control areas, where M> 1, M is an integer.

[0094] Specifically, after reporting the indication information, the sendi...

[0107] image 3 This is a schematic diagram of a control channel detection method provided in the second embodiment of this disclosure, such as image 3 As shown, in the second embodiment, according to the three procedures of beam recovery, assuming that M is 3, configure a first control area before beam recovery. The first control area is generally the receiving end (base station) through high-level signaling Configured, the CORESET(s) (collection of control resources) that need to be detected during normal communication can be one or more, the resources contained in each CORESET can be discontinuous in time and frequency, and resources contained in multiple CORESETs can exist Overlap; configure a second control area during beam recovery. The second control area is generally configured by the base station through high-level signaling. It is the CORESETs that need to be detected during beam recovery. It can be one or more. The resources contained in each CORESET It can be discon...

Abstract

The application provides a detection method, device and system for a control channel. The method comprises the following steps: reporting indication information; detecting M control regions, wherein Mis greater than 1, and M is an integer; and if a configuration change signal of a control region parameter is detected in any control region of the M control regions, detecting the control channel according to the configuration change signal. Through adoption of the detection method, device and system, the robustness of control channel detection can be enhanced, so that the link failure probability in a communication system is lowered.

Description

Technical field [0001] The present disclosure relates to the field of communications, and in particular to a method, device and system for detecting control channels. Background technique [0002] In a wireless communication system, the base station will use the beamforming capabilities of multiple antennas and use narrow beam transmission to effectively improve transmission efficiency. However, the use of narrow beam transmission is more sensitive to the movement of the user equipment (UE) and the blocking of the beam link, especially in high frequency, where the blocking phenomenon is more serious and often causes the failure of the beam link. Therefore, when the wireless channel changes due to the aforementioned reasons, the communication system needs to quickly switch and restore the beam link in order to provide a good user experience. [0003] Generally speaking, the beam recovery technology mainly includes the following steps: [0004] Beam monitoring: mainly to judge the be...
