SYSTEM AND METHODS FOR INTERFERENCE MITIGATION IN FEMTOCELL NETWORK

摘要

Disclosed are system and methods for interference mitigation in femtocell network by dynamically allocating the resource block (RB) to femto user equipment (FUE). The system comprises of at least a sensing module, at least a femto base station (FBS) module and at least a coordination module. The present invention involves a joint channel sensing and radio resource management (RRM) using the sensing module and the femto base station (FBS) module for dynamically allocating resource block (RB) to femto user equipment (FUE). The resource blocks (RBs) are allocated dynamically to femto user equipments (FUEs) by the femto base station (FBS) module based on the instructions of the coordination module.

1. A method for interference mitigation in a femtocell network, the method comprising:
sensing a wireless spectrum over at least a resource block (RB) at a femto base station (FBS) for procuring sensing measurement result (SMR), wherein at least said resource block (RB) is one of at least an allocated resource block (ARB) and at least an unallocated resource block (URB); collecting channel state information (CSI) from at least a Femto User Equipment (FUE); estimating a block error rate (BLER) for at least said resource block (RB); procuring information regarding at least an allocated resource block (ARB) which is already allocated to said at least a femto user equipment (FUE); analyzing at least one of said sensing measurement result (SMR), said collecting channel state information (CSI), said block error rate (BLER), said at least an allocated resource block information (ARBI) or any combination thereof for evaluating a Quality of Service (QoS) performance simultaneously in each of an uplink (UL) communication and a downlink (DL) communication; and dynamically allocating at least a resource block (RB) to at least said Femto User Equipment (FUE) based on said Quality of Service (QoS) performance in each of said uplink (UL) communication and said downlink (DL) communication.
