Abstract
A method for video multicast delivery for 4g wireless networks includes collecting client feedback and obtaining supportable modulation and coding scheme MCS for each client over a base station of wireless network, prioritizing video packets for said clients and setting a utility for each of the video packets; performing a radio resource allocation for determining a utility optimization for transmitted frames of the video packets; and assigning an MCS to each transmitted frame of the video packets, responsive to step performing a radio resource allocation
Claims8
A method for video multicast delivery for 4g wireless networks, said method comprising the steps of:
- collecting client feedback and obtaining supportable modulation and coding scheme MCS
- for each client over a base station of wireless network;
- prioritizing video packets for said clients and setting a utility for each of said video packets;
- performing a radio resource allocation for determining a utility optimization for transmitted frames of said video packets ;
- and
- assigning an MCS to each said transmitted frame of said video packets, responsive to said step of performing a radio resource allocation.
The method of claim 8, wherein once said MCS for each video frame is determined, video packets belonging each frame are marked with an assigned MCS index in a field of an IP header.
Dependencies are inferred from the claim text.
