Abstract
This disclosure relates to techniques for a wireless device to perform channel state information reporting. The wireless device may receive channel state information reporting configuration information. The channel state information reporting configuration information may include an indication to use a wideband precoding matrix indicator format for 3GPP release 16 type II channel state information reporting. The wireless device may perform channel state information reporting using a different reporting configuration than 3GPP release 16 type II channel state information reporting using a wideband precoding matrix indicator format based at least in part on the channel state information reporting configuration information. The wireless device may also or alternatively perform 3GPP type I channel state information reporting using a unified spatial basis selection framework for rank indicators of 3 and 4 for any number of channel state information reference signal ports.
