Sony patents way to skip channel checks for faster wireless links
Sony has been granted a patent for a method that lets a network node reserve extra radio space for a device in an unlicensed channel. Instead of the device checking if the channel is clear every time, the network node checks once and sends a signal to the device, allowing it to use the new space immediately.
In the filing’s own words
Disclosed is a method, performed by a network node, for radio resource pre-reservation for communication of a first wireless device in an unlicensed channel. The method comprises determining an additional spectrum resource allocable for communication based on a successful clear channel assessment procedure conducted by the network node. The additional spectrum resource is different from a first resource used for ongoing communication with the first wireless device. The method comprises transmitting, to the first wireless device, control signalling indicative of the additional spectrum resource.
What exactly they claim (claim 1)
1. A method, performed by a network node, for radio resource pre-reservation for communication of a first wireless device in an unlicensed channel, the method comprising: determining an additional spectrum resource allocable for communication associated with a successful clear channel assessment procedure initiated by the network node, wherein the additional spectrum resource is different from a first resource used for ongoing communication with the first wireless device; and transmitting, to the first wireless device, control signaling indicative of the additional spectrum resource to provide to the first wireless device the additional spectrum resource without a requirement of the wireless device initiating a clear channel assessment, wherein the additional spectrum resource is on an active bandwidth part or on a configured bandwidth part different from an active bandwidth part.
