    Abstract: A method of determining priority rules for periodic CSI reporting in carrier aggregation is proposed. A UE obtains channel state information (CSI) feedback for multiple downlink component carriers (CCs) in a multi-carrier wireless communication network. Each downlink CC is associated with a feedback mode, and each feedback mode comprises a set of feedback types to be reported to a base station at time slots configured by an upper layer. The UE then determines a prioritized downlink CC for CSI reporting based on priority levels of the feedback types to be transmitted for each downlink CC at a given time slot. The UE then transmits the corresponding CSI feedback for the prioritized downlink CC at the given time slot via a feedback channel over a primary uplink CC. In one embodiment, different feedback types are prioritized by groups, and each group has several feedback types sharing the same priority.

    Abstract translation: 提出了一种确定载波聚合中周期性CSI报告优先权规则的方法。 UE在多载波无线通信网络中获得多个下行链路分量载波（CC）的信道状态信息（CSI）反馈。 每个下行链路CC与反馈模式相关联，并且每个反馈模式包括将由上层配置的时隙向基站报告的一组反馈类型。 然后，UE基于在给定时隙处针对每个下行链路CC发送的反馈类型的优先级来确定用于CSI报告的优先级下行链路CC。 然后，UE经由主上行链路CC上的反馈信道在给定时隙上为优先化的下行链路CC发送相应的CSI反馈。 在一个实施例中，不同的反馈类型由组优先，并且每个组具有共享相同优先级的多个反馈类型。

    Abstract: Sounding mechanism for LTE-A systems under carrier aggregation is provided. A UE receives an uplink or downlink grant transmitted from an eNB over a primary carrier in a multi-carrier LTE-A system. The UE determines indicated carrier(s) and detects a triggering condition for aperiodic sounding transmission in the grant. The UE then selects UE-specific sounding reference signal (SRS) parameters. Finally, the UE transmits an aperiodic SRS (ap-SRS) over the indicated carrier(s) using the selected UE-specific SRS parameters. In one embodiment, the uplink or downlink grant is transmitted via a PDCCH carrying various DCI formats. Each DCI format contains a carrier indicator field (CIF) that indicates which carrier is used for ap-SRS transmission if cross-carrier scheduling is enabled. In another embodiment, DCI format 3/3A is transmitted via a PDCCH carrying a plurality of information fields, each field indicates if the UE should enable ap-SRS in a particular carrier.
