Discrete modulation in multiuser nonregenerative relay systems is less investigated in current resource allocation but is more commonly used in practical systems. In this paper, based on a set of discrete modulation levels, we formulate a joint optimization of relay selection and resource allocation under rate requirements to minimize the system transmitting power consumption and to improve energy...
Heterogeneous networks (HetNets) are expected to be one of the major performance enhancement enablers of LTE-Advanced. In order to protect pico-UEs from the strong macro interference, the macro eNBs need to reduce the transmission power during protected subframes instead of suspending data transmission introduced in 3GPP Release 10, scheduling strictly users in the vicinity of the macro eNBs. In this...
Ceramic ball grid array (CBGA) package is becoming increasingly popular as a high-density, high I/O count and highperformance packaging formation in the application of the aviation and spaceflight area. However, the undeveloped rework process restricts the development of the CBGA process and the application of the CBGA component. This paper made a research on the rework process of the CBGA package,...
This paper discusses the content and mechanism of strategic alliance and knowledge management in enterprise, focus on the transfer, sharing, integration, collision and protection of the knowledge; and with China's reality, it proposes a number of countermeasures and proposals about knowledge management when establish corporate strategic alliance, especially multinational strategic alliance. Ensure...
For UTRAN Long Term Evolution (LTE) systems, inter-cell interference is the most important interference source. Inter-cell interference coordination (IOC) is considered to improve coverage and increase data rate at cell edge. The current consensus of IOC scheme is towards semi-static soft frequency reuse (SFR). Due to the limitation of resource configuration way for semi-statci SFR, problems will...
