摘要:
A method of transmitting data in a wireless access system and a packet retransmitting method therein are disclosed. The present invention includes receiving an initial control message including information required for a packet retransmission from a base station, transmitting the packet to be provided with a service from the base station, and if a NACK (non-acknowledgement) signal is received from the base station, retransmitting the packet corresponding to the NACK signal to the base station using the information required for the packet retransmission and included in the initial control message. Therefore, since a separate control message needs not to be transmitted in case of packet retransmission, it is able to save radio resources and reduce an overhead by retransmitting a packet via a previously allocated retransmission region without the separate control message.

A method for releasing resources allocated by persistent scheduling is described. A base station (BS) inserts a persistent allocation release indication message into a control channel, wherein the persistent allocation release indication message includes at least one resource index indicating persistent allocation resources to a mobile station (MS), broadcasts the control channel, and releases the persistent allocation resources corresponding to the resource index. Since a release message for persistent allocation, a channel quality indicator channel, feedback polling allocation, etc. is inserted for transmission into a control channel which can be received by all MSs, overhead which occurs during resource release can be minimized irrespective of transmission rates varying with MSs.

A random access method in a wireless communication system is disclosed. The present invention includes transmitting a bandwidth request indicator and a quick access message from a mobile station to a base station and starting a timer having a timer value determined according to an acknowledgement from the base station.

A method of transmitting and receiving Automatic Repeat reQuest (ARQ) feedback information in a wireless communication system is disclosed. The method of transmitting ARQ feedback information in a wireless communication system includes, at a transmitter, transmitting a Protocol Data Unit (PDU) including an extended header including an ARQ feedback Polling Request (APR) field indicating whether or not the transmitter makes a request for ARQ feedback polling, and receiving an Acknowledgement (ACK) from a receiver if the APR field indicates that the transmitter makes the request for ARQ feedback polling to the receiver.
摘要:
The present invention relates to a method for requesting an uplink resource in a wireless communication system. In the method according to one aspect of the invention, a terminal transmits a quick access message to a base station and receives a resource from the base station. The quick access message includes a first field that shows the attributes of the data that is supposed to be transmitted by the terminal, and a field that is determined by the first field.
摘要:
A method of allocating a paging carrier in a multi-carrier environment is disclosed. The method of allocating the paging carrier includes receiving a first message including first allocation information of the paging carrier, transmitting a second message for requesting entry into an idle mode to a base station; and receiving a third message including second allocation information of a changed paging carrier from the base station. At this time, the paging carrier includes a paging channel out of multiple carriers including one or more carriers.
