摘要
Collision handling of channel state information (CSI) reports is described for enhanced inter cell interference coordination (elCIC) coordinated multipoint transmission (CoMP) and/or carrier aggregation (CA). Various aspects include prioritization schemes to resolve collisions between different CSI reporting sets in relation to the same component carrier (CC) used with transmission. Multiple stages of prioritization may identify CSI for a report based on various criteria. Tie breaker criteria may be defined for priority among CSI reports that changes for different subframes. In other aspects PUSCH is utilized to transmit CSI for prioritized reporting sets in a subframe. In yet other aspects if parallel PUCCH is supported colliding CSI may be handled on a per PUCCH basis. Other aspects may allow for prioritizing periodic CSI within each of multiple CCs and then prioritizing over different CCs to handle an interaction of CSI reports for CA elCIC and/or CoMP.
