Abstract
Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.

transmitting at least one downlink anchor carrier with full 3GPP Release 99 capability; and
transmitting at least one downlink non-anchor carrier with partial 3GPP Release 99 capability, the step of transmitting at least one downlink non-anchor carrier overlapping in time with the step of transmitting at least one downlink anchor carrier.
-
-
122. A machine-readable medium comprising instructions, the instructions, when executed by at least one processor of a base transceiver station in a radio network, cause the base transceiver station to perform operations comprising:
-
transmitting a first downlink anchor carrier with a first common channel;
receiving a first signal from a user equipment device, the first signal notifying the base transceiver station that the user equipment device has acquired radio network system to which the base transceiver station belongs using the first downlink anchor carrier;
transmitting a second downlink anchor carrier with the first common channel, the step of transmitting the second downlink anchor carrier overlapping in time with the step of transmitting the first downlink anchor carrier; and
after receiving the first signal, sending to the user equipment device a second signal, the second signal notifying the user equipment device to acquire the radio network system using the second downlink anchor carrier.
