Abstract
The present invention relates to a method and apparatus for managing a backup channel in a multi-channel environment. According to an aspect of the present invention, the method of managing a backup channel in a multi-channel environment includes transmitting a control region of a super frame through a first channel constituting the multi-channel and transmitting a data region of the super frame to a destination terminal through a second channel constituting the multi-channel. A transmission quality of the first channel is acquired using the control region transmitted through the first channel.
Claims10
A method of a terminal managing a backup channel in a multi-channel environment, the method comprising:
- determining whether to operate in a backup channel use mode or a single channel use mode according to whether the backup channel exists;
- if the backup channel exists, switching to the backup channel use mode and determining a transmission channel and a backup channel;
- measuring a transmission quality of the backup channel;
- updating information about the backup channel by taking a result of the measurement of the transmission quality of the backup channel into consideration;
- and
- transmitting data to a destination terminal through the transmission channel;
- wherein the single channel use mode uses a single channel for transmitting both a control region and a data region;
- and
- wherein the backup channel use mode separates the data region from the control region through the use of multiple channels.
A terminal, comprising:
- a transceiver configured to transmit and receive a radio frame;
- and
- a processor functionally connected to the transceiver,
- wherein the processor is configured to:
- determine whether to operate the terminal in a backup channel use mode or a single channel use mode according to whether a backup channel exists,
- if the backup channel exists, switch to the backup channel use mode and determine a transmission channel and a backup channel,
- measure a transmission quality of the backup channel,
- update information about the backup channel by taking a result of the measurement of the transmission quality of the backup channel into consideration;
- and
- transmit data to a destination terminal through the transmission channel;
- wherein the single channel use mode uses a single channel for transmitting both a control region and a data region;
- and
- wherein the backup channel use mode separates the data region from the control region through the use of multiple channels.
