Abstract
A communication device employs a method and apparatus for transmitting and receiving information in a time slot. When transmitting, the communication device generates user information symbols and positions the symbols in a first portion of the time slot. The first portion of the time slot occupies less time than the time slot. The communication device then transmits the user information symbols during the first portion of the time slot only. When receiving, a communication device decodes and then encodes a received time slot, presuming the received time slot is not a truncated time slot. The communication device determines an error metric for the encoded time slot and, based on the error metric, determines whether the encoded time slot is a truncated time slot. When the encoded time slot is a truncated time slot, the communication device processes the user information symbols in the received time slot.
