Method and system for securing wireless communications

A wireless communication system for securing wireless communications, the system comprising:

• a wireless transmit/receive unit (WTRU);
• a first access point (AP) for transmitting a first portion of a bit stream to the WTRU;
• and
• a second AP for transmitting a second portion of the bit stream to the WTRU, wherein the WTRU is located in an area where a transmission pattern radiated from each of the first and second APs intersect, and the WTRU reassembles the first and second portions into the bit stream.

A wireless communication system for securing wireless communications, the system comprising:

• a wireless transmit/receive unit (WTRU);
• a first access point (AP) for transmitting a first packet data unit (PDU) to the WTRU;
• and
• a second AP for transmitting a second PDU to the WTRU, wherein the WTRU is located in an area where a transmission pattern radiated from each of the first and second APs intersect, and the WTRU performs a function on the first and second PDUs to derive a service data unit (SDU).

In a wireless communication system in which a transmitter sends wireless communications to a receiver, wherein the wireless communications include a sequence of symbols represented by a plurality of primary modulation points of a modulation constellation, a method for securing the wireless communications comprising:

• (a) replacing each primary modulation point with a cluster of secondary modulation points located in close proximity to one another;
• (b) the receiver discriminating between the secondary modulation points in the cluster;
• and
• (c) the receiver demodulating the secondary modulation points to decipher the symbols.

In a wireless communication system including a transmitter and a receiver, the transmitter being configured to transmit wireless communications to the receiver, a method for securing the wireless communications comprising:

• (a) the transmitter transmitting a main waveform which overlays a quadrature phase shift keying (QPSK) signal with hierarchical modulation (HM);
• (b) the transmitter modulating scrambled data in the main waveform;
• (c) the transmitter encoding descrambling information in the HM;
• and
• (d) the receiver extracting the descrambling information in the HM and demodulating the scrambled data when the distance between the receiver and the transmitter does not exceed a particular threshold.
