Abstract
Embodiments of the present disclosure relates to beam failure detection. According to embodiments of the present disclosure, after a serving cell is activated from a deactivated state, a terminal device monitors a beam failure on a serving beam of the serving cell. If a beam failure instance indication is received within a short period after the activation, the terminal device determines that the beam failure is detected on the serving beam. In this way, a beam failure recovery can be quicker triggered to perform candidate beam search.
Claims21
1-52. (canceled)
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- perform an activation procedure on a serving cell which was deactivated;
- monitor a beam failure on a serving beam of the serving cell after activating the serving cell;
- in accordance with a determination that at least one beam failure instance indication is received within a predetermined period, determine that the beam failure is detected on the serving beam;
- and
- transmit a beam failure report to a network device.
A method, comprising:
- performing, at a terminal device, an activation procedure on a serving cell which was deactivated;
- monitoring a beam failure on a serving beam of the serving cell after activating the serving cell;
- in accordance with a determination that at least one beam failure instance indication is received within a predetermined period, determining that the beam failure is detected on the serving beam;
- and
- transmitting a beam failure report to a network device.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- in accordance with a determination that at least one beam failure instance indication on a serving beam of a serving cell is received at a terminal device within a predetermined period after activating the serving cell, receive a beam failure report from the terminal device.
