Method and apparatus for reducing communication latency in a wireless group call
First Claim
1. A method in a wireless handheld communication device for reducing a communication delay at a proximate wireless communication device comprising:
- communicating a first communication on first link to a proximate wireless communication device; and
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.

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.

18. A method in a communication device for reducing the audio latency at a proximate communication device comprising:
-
transmitting a first communication over a first direct link to a proximate communication device; and
transmitting, simultaneously with transmitting said first communication, a second communication to a base station over a second link, different from said first link, wherein said first communication and said second communication are substantially the same.

19. A method in a wireless handheld communication device for reducing a communication delay at a proximate wireless communication device comprising:
-
communicating a first communication on first link to a proximate wireless communication device; and
communicating simultaneously with communicating said first communication, a second communication on a second link, wherein said first communication and said second communication are substantially the same, and wherein communicating said second communication further comprises communicating said second communication to a remote device by relaying said second communication through a base station to said remote device, and wherein a first communication delay associated with said first communication to said proximate wireless communication device is less than a second communication delay associated with said second communication to said remote device relayed through said base station.
