Wireless communication method and device

A first device, comprising:

• a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and execute the computer program stored in the memory to perform a wireless communication method comprising:
• transmitting, by the first device, first information to a second device,
• wherein the first information is used by the second device to determine at least one of:
• a message loss,
• a packet loss,
• a time cycle or time period or condition in which the message loss cannot be tolerated being reached,
• a time cycle or time period or condition in which the packet loss cannot be tolerated being reached,
• modification or reconfiguration or selection satisfying service transmission being triggered,
• reconfiguration or scheduling being triggered, reported survival time not being satisfied, or
• reconfiguration or modification of service transmission being requested towards a peer end;
• wherein said transmitting, by the first device, the first information to the second device comprises:
• transmitting, by the first device, the first information to the second device when a target event is triggered;
• wherein the target event comprises at least one of:
• target packet arrival, packet arrival, packet arrival time obtained, average packet arrival time obtained, maximum packet arrival time obtained, survival time reached, maximum error tolerance time reached, and maximum error reporting tolerance time reached.

A second device, comprising:

• a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and execute the computer program stored in the memory to perform a wireless communication method comprising:
• receiving, by a second device, first information transmitted by a first device,
• wherein the first information is used by the second device to determine at least one of:
• a message loss,
• a packet loss,
• a survival time not being satisfied,
• a time cycle or time period or condition in which the message loss cannot be tolerated being reached,
• a time cycle or time period or condition in which the packet loss cannot be tolerated being reached,
• modification or reconfiguration or selection satisfying service transmission being triggered,
• reconfiguration or scheduling being triggered,
• reported survival time not being satisfied, or
• reconfiguration or modification of service transmission being requested towards a peer end;
• wherein said receiving, by the second device, the first information transmitted by the first device comprises:
• receiving, by the second device, the first information, which is transmitted by the first device when a target event is triggered,
• wherein the target event comprises at least one of:
• target packet arrival, packet arrival, packet arrival time obtained, average packet arrival time obtained, maximum packet arrival time obtained, survival time reached, maximum error tolerance time reached, and maximum error reporting tolerance time reached.
