Abstract
A method for scheduling wireless transmissions in a wireless communications network in the presence of pulsed interference includes receiving pulsed interference information, determining transmission opportunities based on the pulsed interference information, and when a transmission time interval (TTI) is less than a time of an opportunity of the transmission opportunities, transmitting a wireless signal during the opportunity.
Claims14
A method for scheduling wireless transmissions in a wireless communications network in the presence of pulsed interference, the method comprising:
- receiving pulsed interference information;
- determining transmission opportunities based on the pulsed interference information;
- and
- when a transmission time interval (TTI) is less than a time of an opportunity of the transmission opportunities, transmitting a wireless signal during the opportunity,
- wherein determining transmission opportunities includes identifying off-times between radar pulses and determining a buffer time between pulse times, and
- wherein the transmission opportunities are off times between pulses minus the buffer.
A communications system, the system comprising:
- a receiver that receives pulsed interference information;
- a scheduling module that determines transmission opportunities based on the pulsed interference information, and
- a transmitter that transmits a wireless signal during an opportunity of the transmission opportunities when a transmission time interval (TTI) is less than a time of the opportunity,
- wherein determining transmission opportunities includes identifying off-times between radar pulses and determining a buffer time between pulse times,
- wherein the transmission opportunities are off times between pulses minus the buffer.
A method for scheduling wireless transmissions in a wireless communications network in the presence of pulsed interference, the method comprising:
- receiving pulsed interference information;
- determining transmission opportunities based on the pulsed interference information;
- and
- when a transmission time interval (TTI) is less than a time of an opportunity of the transmission opportunities, transmitting a wireless signal during the opportunity,
- wherein determining transmission opportunities includes:
- comparing a TTI to an off time between pulses;
- when the TTI is less than the time between pulses, identifying the transmission opportunities in times between pulses;
- and
- when the TTI is greater than the time between pulses, determining whether a dwell time is present in a pulse pattern.
A communications system, the system comprising:
- a receiver that receives pulsed interference information;
- a scheduling module that determines transmission opportunities based on the pulsed interference information, and
- a transmitter that transmits a wireless signal during an opportunity of the transmission opportunities when a transmission time interval (TTI) is less than a time of the opportunity,
- wherein the scheduling module determines transmission opportunities by:
- comparing a TTI to an off time between pulses;
- when the TTI is less than the time between pulses, identifying a transmission opportunity in the time between pulses;
- and
- when the TTI is greater than the time between pulses, determining whether a dwell time is present in a pulse pattern.
