FIELD: information technology.
SUBSTANCE: techniques for determining and reporting channel quality indicator (CQI) information are described. User equipment (UE) may determine a transmission power per channelisation code, POVSF, based on the available transmission power and a designated number of channelisation codes, e.g., by uniformly distributing the available transmission power across all transport blocks and all of the designated number of channelisation codes. The UE may estimate signal to interference plus noise ratios (SINR) of multiple transport blocks based on POVSF, determine CQI indices for the transport blocks based on the SINR, and send the CQI indices to a Node B. The Node B may send multiple transport blocks to the UE based on the CQI indices. The Node B may send the transport blocks (i) with the designated number of channelisation codes at POVSF or (ii) with a second number of channelisation codes at POVSF, with the transport block sizes being scaled based on the designated and second numbers of channelisation codes.
EFFECT: reduction of noise in wireless communication systems.
