Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Aiming at the problem that misjudgment of the beam state is easy to occur when judging the channel quality without combining the actual sending situation of the reference signal, the present invention provides a beam state detection method and a terminal.
[0021] Such as figure 1 As shown, the embodiment of the present invention provides a beam state detection method applied to a terminal, including:
[0022] Step 101, monitor the indication information;
[0023] Wherein, the indication information is generated by the terminal when no reference signal for beam failure detection is detected; The terminal will detect the reference signal used for beam failure detection. When the reference signal is not detected, it will generate the indicati...

The invention provides a beam state detection method and a terminal, and relates to the technical field of communication. The beam state detection method is applied to a terminal, and includes: monitoring indication information, the indication information is generated by the terminal when no reference signal for beam failure detection is detected; if the indication information is monitored, according to the The above instruction information is used to detect the beam status. In the above solution, by introducing the feature of generating indication information when no reference signal for beam failure detection is detected, the beam state detection is performed according to the indication information, so that the terminal can judge the channel quality according to the actual transmission situation of the reference signal , which ensures the accuracy of beam state detection.
Description
technical field [0001] The invention relates to the field of communication technologies, in particular to a beam state detection method and a terminal. Background technique [0002] A medium access control (Medium Access Control, MAC) entity of a user equipment (User Equipment, UE, also called a terminal) receives a beam failure instance indication (beam failure instance indication) from the physical layer. Each time the MAC entity receives the beam failure indication, it starts or restarts the beam failure detection timer (beamFailureDetectionTimer), and accumulates the beam failure detection counter (BFI_COUNTER). If the beam failure detection timer expires, the beam failure counter is reset (eg, set to "0" value). When the beam failure counter reaches the threshold value configured by the network (eg, beamFailureInstanceMaxCount), the MAC entity considers that a beam failure has occurred, thereby triggering a beam failure recovery process (eg, beam recovery by triggering...
