One wireless communication device includes a transmitter circuit and a control circuit, wherein the control circuit sets a request to send (RTS) frame, and controls the transmitter circuit to transmit the RTS frame via at least one channel excluding a preamble punctured channel. Another wireless communication device includes a transmitter circuit and a control circuit, wherein the control circuit sets an RTS frame, and controls the transmitter circuit to transmit the RTS frame via a plurality of channels including the preamble punctured channel.

Method and apparatus of setting protection frames for protecting transmission of preamble punctured physical layer protocol data unit

A rewritable phase change optical recording medium includes a substrate, a dielectric layer deposited on a surface of the substrate, and an optical recording layer deposited on the dielectric layer, wherein the dielectric layer may be omitted. The optical recording layer contains a composition of GeSbME, wherein 0.5&#x2266;x&#x2266;14.5; 0.5&#x2266;y&#x2266;14.5; 0&#x2266;z&#x2266;14.5; and M and E are different and are selected from the group consisting of Te, Cr, V, Ti, Ag, Sn, Si, Bi, Se, Al, Au, Ni, Fe, Cu, Mn, O, Ga, Cd, In, Pb and Hf, wherein M is not Te, when x is zero; and E is not Sn, when M is Te. The optical recording composition has a small crystal grain, a high ratio of reflectivity of the amorphous phase to that of the crystalline phase thereof, and a high crystallization rate, so that a blue light laser can be used to write/erase the recording medium.
