Method for communicating data, a transmitting unit and a computer program product
The invention relates to a method for communicating data via a shared wifeless channel. The method comprises the steps of preparing a data packet for transmission via the shared wireless channel ( 10 ); detecting any signal presence in the channel ( 20 ); and transmitting the data packet if no signal has been detected in the detecting step C 60 ). Further, the method comprises the step of transmitting the data packet if transmission requirements related to the data packet are met, irrespective of any signal detection in the detecting step ( 30,26 ).
1. A method for communicating data via a shared wireless channel comprising the steps of:
preparing a data packet for transmission via the shared wireless channel;
detecting a signal presence in the shared wireless channel;
transmitting the data packet if no signal is detected in the detecting step; and
transmitting the data packet if transmission requirements related to the data packet are met, irrespective of any signal detection in the detecting step;
wherein the transmission requirements related to the data packet comprise a maximum latency constraint.
2. The method according to claim 1 , further comprising:
preparing a plurality of data packets for transmission via the shared wireless channel, and
wherein in the transmitting step the plurality of data packets is transmitted.
3. The method according to claim 1 , wherein after transmitting a data packet, a time slot is scheduled for transmitting an acknowledgement type signal by at least one device receiving the data packet.
4. The method according to claim 1 , wherein after transmitting the plurality of data packets, a plurality of time slots is scheduled for transmitting an acknowledgement type signal by a device receiving a data packet from the plurality of data packets.
5. The method according to claim 1 , wherein after transmitting one or more data packets a time slot is scheduled for repeated transmission of at least one data packet.
6. The method according to claim 1 , further comprising the steps of:
waiting a waiting time; and
repeating the detecting step if a signal is detected in the detecting step.
7. The method according to claim 1 , further comprising computing a waiting time, the waiting time depending on previous waiting times.
8. The method according to claim 1 , wherein the transmission requirements related to the data packet comprise a transmission priority depending on a data packet type.
9. The method according to claim 1 , wherein a detected signal that is detected in the detecting step is classified in a priority category, and
wherein the data packet is transmitted depending on a relative priority of the detected signal and the data packet, respectively.
10. The method according to claim 1 , further comprising the steps of:
preparing a multiple number of data packets for transmission via the shared wireless channel;
selecting a particular data packet from the multiple number of data packets based on transmission priorities assigned to each of the multiple number of data packets; and
transmitting the particular data packet selected during the selecting step.
11. A transmitting unit for communicating data via a shared wireless channel, the transmitting unit comprising:
a transmitting element arranged for transmitting a data packet via the shared wireless channel; and
a processor arranged for performing the steps of:
preparing a data packet for transmission via the shared wireless channel;
detecting a signal presence in the shared wireless channel;
causing the transmitting element to transmit the data packet if no signal is detected in the detecting step; and
causing the transmitting element to transmit the data packet if transmission requirements related to the data packet are met, irrespective of any signal detection in the detecting step;
wherein the transmission requirements related to the data packet comprise a maximum latency constraint.
12. A non-transitory computer-readable medium having computer-executable instructions for communicating data via a shared wireless channel stored thereon, the computer-executable instructions for causing a processor to perform the steps of:
preparing a data packet for transmission via the shared wireless channel;
detecting a signal presence in the shared wireless channel;
transmitting the data packet if no signal is detected in the detecting step; and
transmitting the data packet if transmission requirements related to the data packet are met, irrespective of any signal detection in the detecting step;
wherein the transmission requirements related to the data packet comprise a maximum latency constraint.
