Abstract:
A method and system is disclosed for dynamic adjustment of auxiliary pilot triggering based on latency. In an example embodiment, an AT that engages in a data communication that requires low latency will transmit its auxiliary pilot unconditionally and without regard to the payload sizes of the packets it transmits. Thus, the AT will not use a comparison of payload packet size with a threshold packet size when determining whether to transmit its auxiliary pilot. Rather, the AT will begin transmitting its auxiliary pilot upon a determination that it is engaged or will engage or has begun to engage in a communication that requires low latency. At the same time, an AT that engages in data communication that does not require low latency will advantageously trigger its auxiliary pilot less aggressively in response to an instruction from the base station to do so.
