摘要

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, CoMP (Coordinated multiple point transmission and reception) and CA (carrier aggregation) are two new features. CoMP is used to improve 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. CA is used to improve the peak rate in LTE-A. It has been widely discussed in 3GPP RAN1. Generally, three kinds of CA are involved, namely the aggregations for continuous carriers, non-continuous intra-band carriers and non-continuous inter-band carriers respectively. In this thesis, under the case of CA, the problem of power allocation for eNBs in the CoMP cooperating set for downlink transmission is discussed, and we propose a power allocation algorithm. Based on the system simulation, the unite rate (bit/sec/Hz) and the corresponding SINR are compared. The possible method of the implementation for this scheme is discussed too.
