Abstract

The present invention relates to methods, devices and computer readable media for beam failure recovery for a secondary cell. A method implemented in a terminal device includes in response to a beam failure on the secondary cell (Scell), transmitting a scheduling request to a network device (220); receiving, from the network device and on a primary cell (Pcell), a response indicating a resource allocated to the terminal device (230); transmitting, to the network device and by using the allocated resource, a beam failure recovery request comprising a beam index of a beam selected from available beams on the Scell by the terminal device, to recover the communication between the terminal device and the network device via the selected beam on the Scell (240).

Description

technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and specifically relate to a method, a device, and a computer-readable medium for beam failure recovery for a secondary cell. Background technique [0002] New Radio Access System, also known as NR system or NR network, is a next generation communication system. It has been agreed that Carrier Aggregation (CA) used in Long Term Evolution (LTE)-Advanced will be supported in the NR system to increase bandwidth. Each aggregated carrier is called a component carrier (CC). When CA is used, there are multiple serving cells, one serving cell per CC. Generally, a primary cell (Pcell) corresponding to a primary CC and at least one secondary cell (Scell) corresponding to at least one secondary CC are provided. [0003] A beam failure may occur when the quality of the serving cell's beam pair(s) is sufficiently low (eg, compared to a threshold or an associated timer expires). B...
