Method and apparatus of controlling data delivery in a wireless communication system for digesting data units outside a reconfigured transmitting window and a reconfigured receiving window

Abstract

A method according to the present invention blocks a sender from processing SDUs required to be transmitted through a radio bearer when a memory block corresponding to the radio bearer is full, and guarantees that every PDUs received by a receiver can be accommodated in a memory block corresponding to a new radio bearer. With regard to data transmission, after a transmitting buffer is reconfigured, PDUs required to be transmitted through a previously established radio bearer are kept and gradually received by the receiver. A new radio bearer is guaranteed to gradually take control of these occupied storage space. With regard to data reception, the receiver outputs WINDOW SUFIs to the sender for dynamically tuning a transmission window size for the new radio bearer so that PDUs transmitted from the sender will never be discarded. To sum up, radio transmission efficiency is greatly improved, and data throughput is optimized.

Description

technical field [0001] The present invention relates to a method and device for controlling data transmission in a wireless communication system, and in particular to a method and device for controlling data transmission between two communication stations to digest data beyond the newly configured transmission window and reception window capacity. Background technique [0002] Please refer to figure 1 . figure 1 A simplified block diagram of a prior art wireless communication system 10 is shown, as defined in the known 3rd Generation Partnership Project (3GPP) standard. The wireless communication system 10 includes a first station 12 in wireless communication with a second station 14 . For example, the first station 12 is a mobile communication unit, such as a mobile phone, and the second station 14 is a base station. The first station 12 and the second station 14 each have a temporary memory 16a, 16b. The buffer memory 16a has a transmit register 17a and a receive regis...

However, for the newly established RB2, the PDUs within its receiving window may be discarded because the radio channel RB1 occupies its configuration space

In other words, this prior art cannot guarantee that the receiving register RW2 of the wireless channel RB2 can receive the PDU with the lowest sequence number in its receiving window, thus reducing the transmission efficiency
