TRANSMITTING STATION AND RECEIVING STATION
A transmitting station includes a first wireless signal processing unit, a second wireless signal processing unit, and a link management unit. The first and second wireless signal processing units are configured to transmit wireless signals using different channels. The link management unit manages link states of the first and second wireless signal processing units. The link management unit is configured to: generate, when first data input is of a specific type, second data that is a duplicate of the first data; attach, first identification information indicating that the first data is original data, to the first data and attach, second identification information indicating that the second data is replicated data, to the second data; and output the first data with the first identification information attached to the first wireless signal processing unit and output the second data with the second identification information attached to the second wireless signal processing unit.
1 . A transmitting station that transmits wireless signals, the station comprising:
a first wireless signal processing circuit configured to transmit a wireless signal using a first channel;
a second wireless signal processing circuit configured to transmit a wireless signal using a second channel different from the first channel;
a processor; and
a storage medium having computer program instructions stored therein that, when executed by the processor, perform to:
manage a link state between the first wireless signal processing circuit and a receiving station that receives wireless signals, and a link state between the second wireless signal processing circuit and the receiving station,
generate, when first data input is of a specific type, second data that is a duplicate of the first data;
attach, first identification information indicating that the first data is original data, to the first data and attach, second identification information indicating that the second data is replicated data, to the second data; and
output the first data with the first identification information attached to the first wireless signal processing circuit and output the second data with the second identification information attached to the second wireless signal processing circuit.
2 . The transmitting station according to claim 1 , wherein
the first identification information indicates that corresponding data is not retransmitted data, and the second identification information indicates that corresponding data is retransmitted data.
3 . The transmitting station according to claim 1 , wherein the first data and the second data are associated with a same sequence number.
4 . The transmitting station according to claim 1 , wherein
the computer program instructions, when executed, perform to set up a primary link using the first wireless signal processing circuit as a main link in a multi-link, and set up a secondary link using the second wireless signal processing circuit as an auxiliary link in the multi-link.
5 . The transmitting station according to claim 1 , wherein a type of the first data is identified based on a traffic type of the data.
6 . The transmitting station according to claim 1 , wherein the specific type of data includes data corresponding to real-time traffic having absolute delay conditions.
7 . A receiving station that receives wireless signals, the station comprising:
a first wireless signal processing circuit configured to receive a wireless signal using a first channel;
a second wireless signal processing circuit configured to receive a wireless signal using a second channel different from the first channel;
a processor; and
a storage medium having computer program instructions stored therein that, when executed by the processor, perform to:
manage a link state between the first wireless signal processing circuit and a transmitting station that transmits wireless signals, and a link state between the second wireless signal processing circuit and the transmitting station,
when first data included in a wireless signal received by the first wireless signal processing circuit is the same as second data included in a wireless signal received by the second wireless signal processing circuit, select the original data out of the first data and the second data referring to identification information respectively attached to the first data and the second data, and discard replicated data.
8 . The receiving station according to claim 7 , wherein the computer program instructions, when executed, perform to, when the original data is not correctly received, select the replicated data and discard the original data.
