Claim 0:
1. A method performed by a user equipment for handling communication via a set of serving cells comprising a first serving cell and a second serving cell of a communication network, the method comprising:
receiving a first uplink grant on the first serving cell, wherein the first uplink grant comprises a first identifier identifying at least one semi-persistent Channel State Information Reference Signal (CSI-RS) resource of the first serving cell, the first uplink grant for the first serving cell including an indication triggering an aperiodic CSI report for CSI for the first serving cell and the second serving cell;
receiving, in the first serving cell, a first CSI-RS in a first CSI-RS semi-persistent resource identified by the first identifier;
calculating a first CSI report for the first serving cell based on the first CSI-RS received in the first using semi-persistent CSI-RS resource identified by the first identifier;
receiving, in the second serving cell, a second CSI-RS in a second semi-persistent CSI-RS resource identified by a second identifier, the second identifier being received previously in a second uplink grant on the second serving cell;
calculating a second CSI report for the second serving cell based on the second CSI-RS received in the second semi-persistent CSI-RS resource of the second serving cell identified by the second identifier; and
transmitting the first and second CSI reports to a network node serving the first serving cell.
