Link recovery method, terminal device, and network device

A link recovery method, comprising:

• transmitting, by a network device, a first signaling and a second signaling to a terminal device, wherein the first signaling indicates one or more reference signals for detecting channel quality information, the second signaling indicates quasi co-location (QCL) information of a physical downlink control channel (PDCCH) and QCL information of the one or more reference signal.

A terminal device, comprising:

• a receiver, configured to receive a first signaling and a second signaling sent by a network device, wherein the first signaling indicates one or more reference signals for detecting channel quality information, the second signaling indicates quasi co-location (QCL) information of a physical downlink control channel (PDCCH) and QCL information of the one or more reference signals.

A network device, comprising:

• a transmitter, configured to transmit a first signaling and a second signaling to a terminal device, wherein the first signaling indicates one or more reference signals for detecting channel quality information, the second signaling indicates quasi co-location (QCL) information of a physical downlink control channel (PDCCH) and QCL information of the one or more reference signals.

A non-transitory, computer-readable medium, storing one or more instructions executable by a terminal device to perform operations comprising:

• receiving, by the terminal device from a network device, a first signaling and a second signaling, wherein the first signaling indicates one or more reference signals for detecting channel quality information, the second signaling indicates quasi co-location (QCL) information of a physical downlink control channel (PDCCH) and QCL information of the one or more reference signals.

A non-transitory, computer-readable medium, storing one or more instructions executable by a network device to perform operations comprising:
