Enabling coexistence of high-density and low-density transmissions

An apparatus to enable coexistence of high-density and low-density transmissions on a medium, the apparatus comprising:

• a transmitter to transmit on the medium comprising a transmit power control to adjust a transmission power to power levels;
• a memory comprising a buffer for storing a network allocation value and a buffer for storing a device associated with the network allocation value;
• and
• logic to determine whether a value of a network allocation vector indicates that the apparatus is blocked from transmitting on the medium;
• to transmit a first clear to send packet at a first power level in response to determining that the apparatus is not blocked from transmitting on the medium, the first clear to send packet comprising a flag or bit to indicate the Shading Transmission Starts (STS);
• to receive a second clear to send packet after transmitting the first clear to send;
• and to transmit a first data transmission at a second power level after receiving the second clear to send, the second power level being less than the first power level.

A computer program product to enable coexistence of high-density and low-density transmissions, the computer program product comprising:

• a computer useable storage medium having a computer useable program code embodied therewith, the computer useable program code comprising:
• computer useable program code configured to perform operations, the operations comprising:
• determining, by a first transmitter, whether a value of a network allocation vector maintained by the first transmitter indicates that the first transmitter is blocked from transmitting on a medium;
• transmitting, by the first transmitter, a first clear to send packet at a first power level in response to determining that the first transmitter is not blocked from transmitting on the medium, the first clear to send packet comprising a flag or bit to indicate the Shading Transmission Starts (STS);
• receiving, by the first transmitter, a second clear to send packet after transmitting the first clear to send;
• and
• transmitting, by the first transmitter after receiving the second clear to send, a first data transmission at a second power level, the second power level being less than the first power level.
