More Information
Summary:Techniques for signaling power information to facilitate channel quality indicator (CQI) reporting are described. A Node B may send power information that may be used by a UE to determine a power per channelization code, P OVSF . In one design, the power information includes a power offset between the power of a data channel, P HSPDSCH , and the power of a pilot channel. The Node B may determine P HSPDSCH based on the power available for the data channel, the number of available channelization codes, and a designated number of channelization codes. The UE may determine P OVSF based on the power information from the Node B and the designated number of channelization codes. The UE may estimate at least one SINR of at least one transport block based on P OVSF , determine CQI information for the transport block(s) based on the SINR, and send the CQI information to the Node B.
