Abstract:
1. A method of data transmission comprising: determining, in response to detecting an error in an original transmission in a wireless communication network, that latency sensitive data in the original transmission would be stale when transmitting a copy of the original transmission; transmitting the copy of the original transmission when a retransmission value function at least equals a predetermined threshold, the retransmission value function being less than the predetermined threshold when a smaller size of the new transmission compared with a size of the copy of the original transmission outweighs a combining gain that would be achieved by transmitting the copy of the original transmission; and transmitting a new transmission when the retransmission value function is less than the predetermined threshold, said new transmission comprising a copy of the data from the original transmission that is not stale when transmitting the new transmission.
