Abstract
A method includes: receiving symbols from antenna(s); calculating average-channel estimates of the symbols over a measurement period; forming a channel matrix from the average-channel estimates; calculating a power ratio between a closed-loop mode and an open-loop mode for each PCI using the channel matrix; calculating RSCP value(s) and ISCP value(s) corresponding to the antenna(s); averaging the RSCP value(s) and ISCP value(s) over the antenna(s) to provide averaged RSCP and ISCP; calculating open-loop SINR from the averaged RSCP and ISCP; calculating SINR for stream(s) for each PCI from the power ratio and the open-loop SINR; determining TBS for a single stream from a single-stream-CQI table using calculated SINR; determining TBS for all streams from a dual-stream-CQI table using calculated SINR; comparing the TBS of the single stream and TBS of the dual stream to determine whether to select single stream or dual stream; and determining PCI and CQI for the stream(s).
