摘要： Apparatuses and methods for indicating and performing interference measurements. A method for performing interference measurements includes identifying a CSI-IM configuration for the UE to perform interference measurement. The method includes determining whether the CSI-IM configuration includes a subset of a total number of frequency resources configured for CSI-IM in the wireless communication system. The method includes measuring interference based on the identified CSI-IM configuration. Additionally, the method includes sending feedback based on the measured interference. The method for performing interference measurements may also include determining whether to perform interference measurements based on all downlink subframes or only a portion of the downlink subframes. Additionally, the method may include performing interference measurement based on the subframe determination.

摘要： A method for CSI report transmission includes detecting a collision in a subframe, between a first PUCCH CSI report of one serving cell with which a UE is configured in one of transmission modes 1 to 9, and a second PUCCH CSI report of another serving cell with which the UE is configured in transmission mode 10. Upon the reporting types of the collided PUCCH CSI reports having a same priority, the method transmits the first PUCCH CSI report if the CSI process index of the second PUCCH CSI report has a positive value other than 1. A method for CSI report transmission includes configuring, via a higher layer, a UE configured in transmission mode 10 whether to create a respective CSI report(s) for each aperiodic CSI process or not, using an information element including at least three one-bit variables.

摘要： Coordinate multi-point (CoMP) transmission is facilitated by resolving collisions between feedback reporting. Based upon the conditions within the network, collision resolution may be by dropping a channel report during a subframe, multiplexing channel reports from a plurality of user equipment, compressing channel reports a plurality of user equipment, and combined reporting, either through joint reports or by using carrier aggregation, for conditions between a user equipment and a plurality of transmission points. New signaling and reporting formats facilitate selection of a collision resolution suitable for current network conditions.
