Claim Text:
1. A method for reducing packet loss during a data transfer to a wireless communication client device over a connection, the method comprising the wireless communication client device: signaling a first receive window size for the data transfer; determining, before a connection interruption event, a time of the connection interruption event that results in an interruption of the connection, the connection interruption event including the wireless communication client device at least temporarily tuning from a first base station to a second base station; and in response to determining the time of the connection interruption event, signaling a second receive window size for the data transfer prior to the connection interruption event to trigger an adjustment of a data rate of the data transfer in preparation for the connection interruption event, wherein the second receive window size is based at least in part on a type of the connection interruption event, wherein types of connection interruption events comprise at least a tune-away event type, a registration event type, a circuit switched fallback (CSFB) event type, and an inter radio access technology (iRAT) transition event type, wherein signaling the second receive window size comprises signaling the second receive window size based at least in part on an indication provided by a physical layer to a higher layer in advance of the connection interruption event, wherein the indication communicates knowledge of a forthcoming interruption in a physical layer connection to a first network, and wherein the indication includes the type of connection interruption event, an event time at which the connection interruption event occurs, and a time duration of the connection interruption event.
