Title: A method of data transmitting for wll terminal
Inventor: CHOI JEONG HUI
IPC: H04B7/24
Filed: 2001-12-22
Abstract: PURPOSE: A data transmission method of a WLL(Wireless Local Loop) RIU(Radio Interface Unit) is provided to enhance a data up-rate by allowing an RIU to transfer the next frame unit data without waiting for a confirm signal from a base station after transmitting the former frame unit data to the base station. CONSTITUTION: A transmission buffer of an RIU is checked to know whether there is a data to be transmitted to a base station(S100). If there is a data to be transmitted, the RIU sets a most significant bit constituting an OH(overhead) of a frame unit to 0(S110) and transmits a data with the highest priority(S120). The RIU checks whether a data to be next transmitted is in a standby state in the transmission buffer(S130). If the data is in a standby state, the RIU sets the most significant bit constituting the OH of the next frame to 1(S140). The RIU transmits the data with the second highest priority to the base station(S150). The RIU judges whether a confirm signal, which confirms that the first data or the second data has been received without an error, has been received from the base station(S160). If the RIU has not received the confirm signal, the RIU re-transmits the data of the corresponding frame to the base station(S170).
