Abstract
Presented is a method for detecting link quality and a terminal device. The method includes that: a terminal device receives a first event reported by a first protocol layer in a second protocol layer, the first event being configured to indicate that quality of a signal in a first signal set is poor enough to meet a first condition; and the terminal device determines that a second event occurs in the second protocol layer based on the first event, the second event being configured to indicate that quality of a link corresponding to the signal in the first signal set is poor enough to meet a second condition. The method and terminal device are favorable for improving signal transmission performance.
Claims14
A method for detecting link quality, comprising:
- receiving in a second protocol layer, by a terminal device, a first event reported by a first protocol layer, wherein the first event indicates that qualities of one or more signals in a first signal set meet a first condition, and the one or more signals in the first signal set comprise a channel state information reference signal (CSI-RS);
- wherein the qualities of the one or more signals in the first signal set meet the first condition, in case that a block error rate of each signal in the first signal set is greater than or equal to a second value;
- starting or restarting, by the terminal device, a second timer, whenever the first event is received in the second protocol layer, and receiving in the second protocol layer, by the terminal device, the first event within a duration of the second timer;
- adding, by the terminal device, 1 to a counter, when the terminal device receives the first event in the second protocol layer within the duration of the second timer;
- clearing, by the terminal device, the counter, when the terminal device does not receive the first event in the second protocol layer within the duration of the second timer;
- and
- determining in the second protocol layer, by the terminal device, based on a counting condition of the counter, that a second event occurs, wherein the second event indicates that qualities of one or more links for the one or more signals in the first signal set meet a second condition.
A terminal device, comprising:
- an input interface, configured to receive a first event reported by a first protocol layer in a second protocol layer, wherein the first event indicates that qualities of one or more signals in a first signal set meet a first condition, and the one or more signals in the first signal set comprise a channel state information reference signal (CSI-RS);
- wherein the qualities of the one or more signals in the first signal set meet the first condition, in case that a block error rate of each signal in the first signal set is greater than or equal to a second value;
- a processor, configured to:
- start or restart a second timer, whenever the first event is received in the second protocol layer, wherein the terminal device receives the first event in the second protocol layer within a duration of the second timer;
- add 1 to a counter when the first event is received in the second protocol layer within the duration of the second timer;
- clear the counter, when the first event is not received in the second protocol layer within the duration of the second timer;
- and
- determine in the second protocol layer, based on a counting condition of the counter, that a second event occurs, wherein the second event indicates that qualities of one or more links for the one or more signals in the first signal set meet a second condition.
