Abstract
Apparatus and methods that mitigate interferences between two vehicle-to everything (V2X) communications channels to maintain a sufficient communication range for both channels. A method comprises, in a V2X communication unit, detecting energy of an adjacent channel, or current and future scheduled transmission in the adjacent channel, if available, the adjacent channel being adjacent to a main channel, and if adjacent channel transmission is detected, deferring transmission in the main channel to maintain a sufficient communication range for both the main channel and the adjacent channel.
Claims18
A vehicle-to everything (V2X) communication unit, comprising:
- a) a PHY module that includes an adjacent channel energy detection module operative to detect ongoing transmission in an adjacent channel based on energy, the adjacent channel being adjacent to a main channel;
- and
- b) a MAC module that includes a transmission deferral module operative to receive an adjacent channel energy value detected by the adjacent channel energy detection module, and, based on a comparison of the received adjacent channel energy value with a detection threshold, operative to defer transmission in the main channel to maintain a sufficient communication range for both the main channel and the adjacent channel.
A vehicle-to everything (V2X) communication unit, comprising:
- a MAC module that includes a transmission deferral module operative to receive and process an input related to an adjacent channel, wherein the input includes current and next C-V2X allocations and their past RSSI values, and, based on the input, operative to defer transmission in a main channel to maintain a sufficient communication range for both the main channel and the adjacent channel.
A method, comprising:
- in a vehicle-to everything (V2X) communication unit:
- a) detecting energy of an adjacent channel, the adjacent channel being adjacent to a main channel;
- and
- b) if adjacent channel energy is detected, deferring transmission in the main channel to maintain a sufficient communication range for both the main channel and the adjacent channel.
A method, comprising:
- in a vehicle-to everything (V2X) communication unit in which communications occur in a main channel and in an adjacent channel:
- a) receiving an input related to the adjacent channel, that includes current and next C-V2X allocations and their past RSSI values;
- b) processing the input;
- and
- c) deferring transmission in the main channel based on the processed input, to maintain a sufficient communication range for both the main channel and the adjacent channel.
