Methods for accessing to base station that uses sack mechanism and apparatuses using the same

摘要

A method for mobile station accessing to a base station in a wireless communication system that uses selective acknowledgement mechanism, comprising: transmitting, an access probe from the mobile station to the base station;
receiving, a message from the base station, wherein the message indicates parts of the plurality of data frames are not decoded by the base station; passing, an instruction from a MAC layer to a PHY layer of the mobile station, wherein the instruction is used to send a selective acknowledgement header; sending, the parts of data frames that are not decoded by the base station from the MAC layer to the PHY layer according to the message; and retransmitting the parts of the plurality of data frames.

1. A method of a mobile station to access to a base station in a wireless communication system that uses selective acknowledgement mechanism, comprising:
transmitting, a first access probe from the mobile station to the base station, wherein the first access probe includes a plurality of data frames; receiving, a message sent from the base station, wherein the message indicates that parts of the plurality of data frames in the first access probe are not decoded by the base station; before sending a selective acknowledgement header from a MAC layer of the mobile station to a PHY layer of the mobile station, sending an instruction from the MAC layer of the mobile station to the PHY layer of the mobile station, wherein the instruction indicates to the PHY layer that the MAC layer will send the selective acknowledgement header, sending the selective acknowledgement header from the MAC layer of the mobile station to the PHY layer of the mobile station; sending the parts of the plurality of data frames that are not decoded by the base station from the MAC layer to the PHY layer according to the message; and retransmitting, by the mobile station to the base station, the parts of the plurality of data frames that are not decoded by the base station.
