Abstract
A packet data transmission method of the HSDPA system includes collecting information on the quality of physical channels, a status of the MAC buffer, the priority level of data, the delay of data, and the like, determining the transmission order of data and the size of a data block to be transmitted based on the collected information, and transmitting the data block through the physical layer according to the order of transmissions. Since the HSDPA scheduler takes into account the delay of data, the quality of real-time services can be improved.
Claims18
A method of transmitting data in a High Speed Downlink Packet Access (HSDPA) system, the method comprising:
- receiving data and scheduling control information related to the data;
- scheduling the data in accordance with the scheduling control information;
- and
- transmitting the data according to the scheduling,
- wherein the scheduling control information comprises priority information indicating a priority of the data, and delay information indicating a data transmission delay or a latency of the data,
- wherein the data transmission delay or the latency of the data occurs within at least one network element or between at least two network elements, and
- wherein the at least one network element is a radio link control (RLC) layer, a medium access control (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.
An apparatus of transmitting data in a High Speed Downlink Packet Access (HSDPA) system, comprising:
- a receiver to receive data and scheduling control information related to the data;
- a scheduler to schedule the data in accordance with the scheduling control information;
- and
- a transmitter to transmit the data according to the scheduling of the scheduler, wherein the scheduling control information comprises priority information indicating a priority of the data, and delay information indicating a data transmission delay or a latency of the data,
- wherein the data transmission delay or the latency of the data occurs within at least one network element or between at least two network elements, and
- wherein the at least one network element is a radio link control (RLC) layer, a medium access control (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.
