Patent ID: 7619985

Claim:
A method of transmitting data in a mobile communications system having a radio interface protocol with an upper layer, a medium access control (MAC) layer including a buffer, and a physical layer, the method comprising: receiving data from the upper layer; receiving buffer status information from the buffer; receiving channel status information from the physical layer; obtaining scheduling control information indicating a data transmission delay or a latency of the data and indicating a priority of the data; scheduling the data in accordance with the buffer status information, the channel status information and the scheduling control information; and transmitting the data through the physical layer according to the scheduling, wherein the data transmission delay or the latency occurs within at least one network element or between at least two network elements, wherein the at least one network element is a radio link control (RLC) layer, a MAC layer, a radio network controller (RNC), or a base station (Node B), and the at least two network elements comprise a RNC and a base station (Node B) or comprise a RLC layer and a MAC layer, wherein the at least one network element or the at least two network elements support a high speed downlink packet access (HSDPA) system, wherein the information indicating the data transmission delay or the latency is transmitted through a frame protocol, and wherein the frame protocol comprises a delay field indicating the data transmission delay or the latency.
