Abstract  Abstract

Multi-carrier point-to-multipoint CDMA system implementations reduce hardware changes in conventional single-carrier systems. The number of common downlink channels, such as timing / synchronization and call channels, is reduced by storing an anchor carrier for transmitting the channels. Procedures for adding carriers and carrier acquisition are simplified by the common carrier timing, timing offsets by the network and signaling of the scrambling code selection to the user equipment (UE), and other measurements. Channel reuse is used to minimize changes in asymmetrical systems according to different numbers of uplink and downlink carriers. The Channel Quality Indicator (CQI) field is divided into a number of subfields to enable the transmission of multiple CQIs and ACK / NAK indicators on one uplink carrier. Common and separate scheduling schemes are shown for simultaneous scheduling of data stream transmissions to a UE over multiple downlink carriers.
