Abstract

A wireless handheld communication device (102) for reducing a communication delay at a proximate wireless communication device is disclosed. The wireless handheld communication device simultaneously transmits to a remote station (106) through a base station (108), and transmits to the proximate wireless communication device (104) directly. The method includes communicating a first communication on first link (116) to a proximate wireless communication device and communicating, simultaneously with communicating the first communication, a second communication on a second link (112) to a base station, wherein the first communication and the second communication are substantially the same.

Claims

1. A wireless communication device comprising:

a microprocessor;

a transmitter coupled to said microprocessor, said transmitter capable of transmitting on a first link and a second link simultaneously;

a proximate device communication module coupled to said microprocessor, said proximate device communication module communicating a first communication on first link to a proximate wireless communication device; and

a wide area network communication module coupled to said microprocessor, said wide area network module communicating, simultaneously with communicating said first communication, a second communication on a second link to a base station, wherein said first communication and said second communication are substantially the same.

2. The device of claim 1, wherein said wide area network communication module is configured to communication to a wireless local area network.

3. The device of claim 1, wherein said proximate device communication module is configured to communicate over a local area network.
