Methods for retransmitting reverse link data and apparatuses using the same

摘要

A method for retransmitting reverse link data practiced by a media access control layer, the method comprising: buffering a plurality of data frames encapsulated in a first access probe in a memory; obtaining information regarding data frames encapsulated in the first access probe that are successfully decoded by a telecommunication network; selecting the buffered data frames that are required to be retransmitted, according to the obtained information; and passing down the selected data frames to a physical layer, to encapsulate the selected data frames into a second access probe and transmit the second access probe to the telecommunication network.

1. A method for retransmitting reverse link data practiced by a subscriber device, the method comprising:
receiving by a media access control (MAC) layer of a plurality of data frames of a first access probe from a link access control (LAC) layer, wherein the LAC layer indicates a selective acknowledgement (SACK) that is included on the plurality of data frames. buffering the plurality of data frames by the MAC layer; transmitting by a physical layer of the buffered plurality of data frames to a telecommunication network, wherein the transmitted plurality of data frames are encapsulated in a first access probe; in response to the transmission of the plurality of data frames, determining whether a SACK order corresponding to the first access probe is received by the MAC from an upper layer of the LAC layer; in response to receiving of the SACK order:
obtaining information regarding the plurality of data frames encapsulated in the first access probe that were successfully decoded by the telecommunication network;selecting at least one of the plurality of the buffered data frames that are required to be retransmitted, according to the obtained information, wherein the successfully decoded plurality of data frames are stored in a memory and taken out from the buffered plurality of data frames;passing down the selected at least one of the plurality of data frames to the physical layer, to encapsulate the selected at least one of the plurality of selected data frames into a second access probe and transmit the second access probe to the telecommunication network;storing the retransmitted at least one of the plurality of selected data frames in the memory; in response to non-receiving of the second SACK order:
passing down all of the buffered plurality of data frames to the physical layer for retransmission to the telecommunication network.
