FIELD: radio engineering, communication.
SUBSTANCE: procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signalling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimise changes in asymmetric systems with different numbers of uplink and downlink carriers. The 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 UE via multiple downlink carriers.
EFFECT: number of common downlink channels, such as timing, synchronisation and paging channels, is reduced by designating a reference carrier for transmitting these channels.
