Information transmission method and device, first equipment and second equipment

Abstract

The invention provides an information transmission method and device, first equipment and second equipment, and the method comprises the steps: sending a beam failure recovery (BFR) request to the second equipment in a time slot N, and executing a preset receiving scheme for control information on a first control resource set CORESET from the time slot N + K; wherein N is an integer greater than or equal to 0, and K is an integer greater than or equal to 0. According to the scheme, a beam failure recovery (BFR) request is sent to second equipment in the time slot N, and a preset receiving scheme is executed on control information on a first control resource set CORESET from a time slot N + K, wherein N is an integer greater than or equal to 0, and K is an integer greater than or equal to 0. In this way, the situation that the system cannot work normally or the system performance is reduced due to behavior mismatching of the base station and the terminal UE can be avoided to a certain extent. The problem that the system performance is reduced due to the fact that the sending and receiving of the control information on the existing CORESET are not defined after the UE monitors the beam failure and reports the BFR request is solved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information transmission method, device, first device and second device. Background technique [0002] Currently, a wireless transmitter with multiple antennas (such as a base station gNB) can form a narrow wireless signal pointing in a specific direction (such as beamforming). The width and direction of the beam can be flexibly adjusted by applying appropriate weights at each antenna element. Beamforming can be in the digital or analog domain. For digital beamforming, each antenna element has a separate baseband module, and each antenna element can independently control the amplitude and phase of the signal transmitted on it, thus, the digital beam can be narrowband (e.g., with a higher frequency than the total narrower system bandwidth). Different digital beams can be multiplexed in time domain or frequency domain. For analog beamforming, multiple anten...

Problems solved by technology

[0008] The purpose of the present invention is to provide an information transmission method, device, first device, and second device to solve the problem of sending control information on the existing CORESET after the UE detects a beam failure and reports a BFR request in the prior art. Receive is not defined, leading to the problem of system performance degradation
