FIELD: information technology.
SUBSTANCE: techniques for signalling power information to facilitate channel quality indicator (CQI) reporting are described. A Node B may send power information which may be used by UE to determine a power per channelisation code (Posvf) In one design, the power information includes a power offset between the power of a data channel (Phspdsch), and the power of a pilot channel. The Node B may determine Phspdsch based on the power available for the data channel, the number of available channelisation codes, and a designated number of channelisation codes. The UE may determine Povsf based on the power information from the Node B and the designated number of channelisation codes. The UE may estimate at least one SINR of at least one transport block based on Povsf, determine CQI information for the transport block(s) based on the SINR, and send the CQI information to the Node B.
EFFECT: easy accurate determination and transmission.
