Abstract:
The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.
