Abstract
Abstract The present invention is a novel and improved method and system for communicating a frame of information according to a discontinuous transmit format. In particular, the present invention describes a method of transmitting eighth rate speech or data frames employing transmit gating and energy scaling which simultaneously reduces the battery usage of a variable rate wireless communication device, increases the capacity of the reverse link and provides reliable communication of the eighth rate frames. In the present invention, four methods are presented for transmitting an eighth rate data frame in which half of the frame is gated out and the remaining data is transmitted at nominal transmission energy to accomplish the aforementioned goals. In addition, a power control system in which identifies forward link power control bits that .1have been gated out by the remote station and inhibits adjustment of the transmission energy in response to that identification is disclosed.
