A method for providing improved reverse link transmission timing in an access terminal is provided. The method includes processing automatic repeat request (ARQ) bits from a MAC bit processing unit for a previous sub-frame. The ARQ bits comprise a hybrid ARQ (H-ARQ) bit, a last ARQ (L-ARQ) bit, and a packet ARQ (P-ARQ) bit. The method also includes calculating the maximum allowed reverse rate and grant size for a MAC flow. The method further includes distributing grants to each application in the MAC flow. The method also includes storing a stored read pointer in an application transmit queue, for each application in the MAC flow. The method also includes preparing data for transmission, in response to storing the stored read pointer for each application in the MAC flow, based on the ARQ bits. The method also includes transmitting the data.

Apparatus and method for reverse link transmission in an access terminal

A mobile communication device for providing QoS of packet transmission is provided. The packet transmission from and to the mobile communication device is performed by repeating a predetermined number of interlaces by a predetermined cycle. In the mobile communication device, a wireless module transmits a first sub-packet of a first packet and a first sub-packet of a second packet to a mobile communication network, and receives a response message corresponding to the first sub-packet of the first packet from the mobile communication network, wherein the first sub-packet of the first packet is transmitted in a first interlace prior to a second interlace in which the first sub-packet of the second packet is transmitted. Also, a controller module calculates a plurality of QoS parameters for a second sub-packet of the second packet in response to the response message, prepares the second sub-packet of the second packet with the QoS parameters, and transmits the second sub-packet of the second packet in the second interlace to the mobile communication network via the wireless module.
