Claim of US Patent No. 10,694,523

1. A method for communicating in a first wireless communication network, the method comprising:setting, at a communication device in the first wireless communication network, a power threshold level to a value from among a set of different values that includes at least a maximum value and a minimum value, the power threshold level for use in determining whether a communication channel is idle, the power threshold level being set to a value that is above the minimum value;
using, at the communication device, the power threshold level set to the value above the minimum value to determine whether the communication is idle;
determining, at the communication device and while using the power threshold level set to the value above the minimum value to determine whether the communication is idle, that a transmission is to be performed during a spatial reuse opportunity corresponding to a transmission in a second wireless communication network;
determining, at the communication device, a transmit power to use for transmission during the spatial reuse opportunity, the transmit power being determined using the power threshold level set to the value above the minimum value; and
transmitting, by the communication device, a packet during the spatial reuse opportunity at the transmit power that was determined using the power threshold level set to the value above the minimum value.
