Abstract
A method by a device of communicating with a wireless access point is disclosed. The method includes receiving information that characterizes intended future transmissions of one or more other devices. The method includes controlling transmission of a packet to the wireless access point based on the information. Related access points, methods by devices, and devices are disclosed.
Claims17
A method by a device of communicating with a wireless access point, the method comprising:
- receiving information from the wireless access point that characterizes intended future transmissions of one or more other devices other than the device and other than the wireless access point, wherein the information comprises an aggregated information set indicating time slots that will be used for future transmission by the one or more other devices;
- and
- controlling transmission of a packet by the device directly to the wireless access point based on the aggregated information set, wherein the controlling transmission comprises controlling timing of transmission of the packet on a same one of the channels indicated by the aggregated information set but in a time slot selected based on the time slots indicated by the aggregated information set.
A device for communicating with a wireless access point, the device comprising:
- a receiver configured to receive information from the wireless access point that characterizes intended future transmissions of one or more other devices other than the device and other than the wireless access point, wherein the information comprises an aggregated information set indicating time slots that will be used for future transmission by the one or more other devices;
- and
- a processor configured to control transmission of a packet by the device directly to the wireless access point based on the aggregated information set by controlling timing of transmission of the packet on a same one of the channels indicated by the aggregated information set but in a time slot selected based on the time slots indicated by the aggregated information set.
