Power control in wireless networks

An apparatus for wireless communication, comprising:

• means for measuring an energy level of a transmission channel;
• means for comparing the measured energy level to a first threshold energy level, wherein the first threshold energy level corresponds to a first state of the transmission channel and to an energy detection threshold level associated with a clear channel assessment;
• and
• means for determining whether to transmit data in the transmission channel based on the comparison, wherein the measured energy level is greater than the first threshold energy level, and wherein the means for determining is configured to:
• reduce a transmission power of the apparatus;
• and
• transmit the data in the transmission channel at the reduced transmission power.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• measure an energy level of a transmission channel;
• compare the measured energy level to a first threshold energy level, wherein the first threshold energy level corresponds to a first state of the transmission channel and to an energy detection threshold level associated with a clear channel assessment;
• and
• determine whether to transmit data in the transmission channel based on the comparison, wherein the measured energy level is greater than the first threshold energy level, and wherein the at least one processor is configured to:
• reduce a transmission power of the apparatus;
• and
• transmit the data in the transmission channel at the reduced transmission power.
