LI Delay Impact on ICIC in Type 1 Relay

3GPP LTE specification is stable now in release 8. To meet much higher requirements than release 8, 3GPP has initiated the LTE-A (LTE-Advanced) study item. In LTE-A, some new features are introduced in, such as relay, CoMP (Coordinated multiple point transmission and reception) and CA (carrier aggregation) . Relay is used to improve cell coverage and to increase cell-edge throughput. It is considered as an effective approach for ICIC (inter-cell interference coordination) in LTE-A due to inherent joint scheduling/processing at the coordinated cells.
