Claim of US Patent No. 9,491,721

1. A method of operating a Long Term Evolution (LTE) access node to dynamically modify power headroom (PHR) prohibit timers,
the method comprising:
receiving wireless signals from a plurality of wireless communication devices using a first PHR prohibit timer, wherein the
plurality of wireless communication devices comprises one or more device to device (D2D) communication groups;

determining a signaling load for the plurality of wireless communication devices;
determining whether the signaling load meets signaling criteria;
if the signaling load meets the signaling criteria, identifying a second PHR prohibit timer, wherein the second PHR prohibit
timer is higher than the first PHR prohibit timer; and

if the signaling load meets the signaling criteria, receiving network access requests from a second plurality of wireless
communication devices and providing the second plurality of wireless communication devices with the second PHR prohibit timer,
wherein the second plurality of wireless communication devices comprises one or more additional D2D communication groups.
