Abstract
Wireless communication techniques are described in which control and data are separated. In an implementation, a method is described which includes sending data packets on one or more wireless channels and sending control data relating to the data packets on at least one other wireless channel having a data rate that is lower than a data rate of the one or more wireless channels.
Claims17
A method comprising:
- sending data packets by a radio transceiver on one or more wireless channels having a first frequency band;
- sending control data by said radio transceiver or a second radio transceiver relating to the data packets on at least one other wireless channel having a second frequency band that is lower than the first frequency band, the second frequency band being noncontiguous with the first frequency band;
- receiving data from an application;
- forming data packets from the received data into a packet train;
- and configuring the packet train for communication over the one or more wireless channels during a period of time specified by a single reservation communicated on the other wireless channel.
2 more elements
A method comprising:
- sending a set of data packets via a radio transceiver on one or more wireless channels using a band having a first frequency;
- and
- sending control data via said radio transceiver or a second radio transceiver on at least one other wireless channel using a band having a second frequency, wherein the second frequency is lower than the first frequency and is non-contiguous with the second frequency, wherein the control data is configured to reserve a time on the one or more wireless channels to send another set of data packets
- forming the another set of data packets into a packet train that is configured for communication over the one or more wireless channels during the reserved time;
- and
- receiving a single acknowledgement indicating which of the data packets, if any, that were included in the packet train were not received.
3 more elements
A method comprising:
- receiving by a radio transceiver data from an application;
- forming, from the data that is received, first and second sets of data packets;
- sending the first set of data packets via said radio transceiver via a first frequency band on one or more wireless channels;
- sending contention control data by said radio transceiver or a second radio transceiver relating to the second set of data packets via a second frequency band on at least one other wireless channel simultaneously during the sending of the first set of data packets, wherein the second frequency band has a lower frequency than and is noncontiguous with the first frequency band;
- and
- forming the second set of data packets into a packet train that is configured for communication over the one or more wireless channels during a period of time specified by a single reservation communicated on the other wireless channel via the second frequency band.
