In LTE Release 11, an advanced receiver that employs interference rejection combining (IRC) was investigated for user equipment(UE) with two receiver (Rx) antennas . Thus, further study on the IRC receiver with more Rx antennas (e.g., four or eight) will be a natural extension in LTE-B in order to utilize the increased degrees of freedom at the UE receiver for suppressing multiple interference resources, as shown in Fig. 3b1. CoMP technologies considering the IRC receiver (e.g., interference alignment ) may be a potential topic for future steps beyond LTE-B, although this might to some extent be achieved through eNB implementations.
