Methods, Apparatus and Device-Readable Mediums Relating to Wireless Access in a Network Requiring a Carrier-Sense Mechanism - A simplified explanation of the abstract
This abstract first appeared for US patent application 18318069 titled 'Methods, Apparatus and Device-Readable Mediums Relating to Wireless Access in a Network Requiring a Carrier-Sense Mechanism
Simplified Explanation
The patent application is about wireless access in a network that requires a carrier-sense mechanism.
- The method involves transmitting from one device to another in a wireless communications network.
- The transmitting device has multiple antenna elements.
- The method includes performing a directional carrier-sense assessment for specific sub-bands used for transmissions between the devices.
- Beamforming is used to detect the level of wireless activity on each sub-band in a particular direction.
- Based on the detected level of wireless activity, a respective transmit power is selected for each sub-band.
- The transmitting device then transmits to the receiving device in the particular direction, using the selected transmit power for each sub-band.
Original Abstract Submitted
Methods, apparatus, and device-readable mediums are disclosed relating to wireless access in a network requiring a carrier-sense mechanism. One aspect provides a method performed by a transmitting device for transmitting to a receiving device in a wireless communications network. The transmitting device comprises a plurality of antenna elements. The method comprises: performing a directional carrier-sense assessment for one or more sub-bands configured for transmissions between the transmitting device and the receiving device, the directional carrier-sense assessment utilizing beamforming to detect a respective level of wireless activity on each of the sub-bands in a particular direction for transmissions to the receiving device; selecting a respective transmit power for each sub-band based on the determined level of wireless activity; and transmitting to the receiving device in the particular direction, using the respective selected transmit power for each sub-band.
