Abstract
A novel and useful method and system for control channel signaling for use in multiple access wireless communication systems. The control message portion of the frame is divided into two portions: a first portion for transmitting a list of u-ID information and a second portion for transmitting all other remaining control information. All user identification information (u-ID information) is placed at the beginning of the control portion of a frame, typically in one or two symbols sent in the earliest part of the frame. The remaining control information (i.e. resource allocation and decoding information) is sent in the second portion of the control message. Users that do not have a resource assignment in a frame can skip the remainder of the frame, including the rest of the control message and data, and shutdown their receivers thus reducing power consumption. Only those UEs served in the current frame need to continue reception and decoding of the remainder of the control message and subsequent data.
