1. A method performed by an originator, the method comprising:
sending, to a receiver, a request for negotiating a size of a transmission window with the receiver for an acknowledged information transfer through reliable data service (RDS) protocol, wherein the request comprises a first parameter indicating a first size of the transmission window expected to be used by the originator; and
receiving, from the receiver, a response to the request, wherein the response to the request comprises a second parameter indicating a second size of the transmission window expected by the receiver, the second size of the transmission window being smaller than or equal to the first size of the transmission window,
wherein performing the acknowledged information transfer comprises:
when the second size of the transmission window is greater than 3, performing the acknowledged information transfer with at least one extended frame header format;
wherein the at least one extended frame header format is an extension of at least one normal frame header format used when the second size of the transmission window is smaller than or equal to 3.
