Tandem mass tag (TMT) mass spectrometry is a mainstream isobaric chemical labeling strategy for profiling proteomes. Here we present a 29‐plex TMT method to combine the 11‐plex and 18‐plex labeling strategies. The 29‐plex method was examined with a pooled sample composed of 1×, 3×, and 10× Escherichia coli peptides with 100× human background peptides, which generated two E. coli datasets (TMT11 and...
The dynamic TDD DL/UL configuration based on instantaneous asymmetric DL/UL traffics is an effective way to increase the radio resource utilization. However, free reconfiguration of each cell's TDD DL/UL configuration may result in significant co-channel co-subframe DL-UL interference. In this paper, we propose and evaluate a novel centralized cell clustering interference mitigation scheme for dynamic...
Dynamic inter-cell interference coordination (ICIC) is a multi-point cooperation technology that has attracted significant interest for inter-cell interference mitigation in wireless communication systems due to its potential performance gain, robustness and relatively low complexity. This paper describes mechanisms for implementation of dynamic ICIC as well as the standardized support that exists...
Coordinated multi-point transmission (CoMP) has been regarded as one of the key LTE-A technologies. Various CoMP schemes has been extensively investigated,and coherent joint transmission scheme (CJT) has been demonstrated to extract the largest CoMP gains in both cell average performance and cell edge performance. In CJT scheme, multiple coordinated cells constitute a supper cell adopting centralized...
As one of the key LTE-A technologies, coordinated multi-point transmission (CoMP) has been extensively investigated. Among various CoMP schemes, coherent joint transmission scheme (CJT) shows the largest CoMP gains in both cell average performance and cell edge performance. However, for pursuit of the upper bound of CoMP gains, centralized scheduling was adopted in those proposed CJT schemes. With...
In 3GPP LTE-Advanced Release-12, the feature of dual connectivity (DC) has been introduced to enhance small cell networks from the aspects of higher layer architecture and physical layer procedures, which can improve mobility robustness and per-user throughput as well as avoid frequent hard handover among small cells. To guarantee the UE maximum transmit power is not exceeded, the conventional power...
The multi-user eigen transmission (MET) scheme has been extensively investigated in multi-user multiple-input multiple-output (MU-MIMO) downlink transmission due to its remarkable performance at low computational complexity. Based on the existing solutions of MET discussed in open literatures, we propose an enhanced MET (eMET) scheme in this paper in order to further enhance the performance of cellular...
Coherent joint transmission (CJT) algorithm has been extensively investigated in multi-cell cooperative downlink transmission due to its huge potential performance gains. Comparing with the existing CJT algorithm based on the multi-user eign-mode transmission, an enhanced CJT (eCJT) algorithm is proposed in this paper to further enhance the performance of cellular network in terms of spectral efficiency,...
Coordinated multipoint (CoMP) processing is a key enabling technique in Long Term Evolution-Advanced (LTE-A) to improve the system spectral efficiency. Among the CoMP processing schemes, while joint transmission (JT) from multiple coordinated eNBs has high computing complexity due to the data sharing, coordinated scheduling/coordinated beamforming (CS/CB) lowers the backhaul requirement. In this paper,...
Heterogeneous deployment is a promising solution to enhance both system capacity and coverage, where the planned macro cell is overlaid with pico cells. However, higher transmit power of macro eNB (MeNB) results in small coverage for pico cell, which causes insufficient offloading from macro cell to pico cell and inefficient cell splitting gain exploration. Cell range expansion (CRE) is one of alternative...
This paper presents various methods of multi-beam laser interference lithography to form dense periodical nanostructures suitable for many optical functional materials or devices. Research results show that 2D and 3D inference patterns could be generated cheaply and easily by exposing the photosensitive materials using the periodically changed light intensity distributions of multi-beam interference...
Coordinated multipoint (CoMP) transmission is capable of significantly improving both the cell average and cell-edge performance in terms of spectral efficiency (SE). It is therefore regarded as a key enabling technique in the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE)-Advanced. Early research mainly concentrates on coordinated transmissions from several eNBs. Recently, coordination...
Designing transmit precoding vectors based on maximizing signal-to-leakage-and-noise ratio (SLNR) provides a practical solution to the coupling problem encountered in the conventional designing methodology by maximizing signal-to-interference-plus-noise ratio (SINR). In this contribution, a simple but sophisticated iterative algorithm is proposed to find the optimal power allocation for the sake of...
We propose a linear precoding technique, called multiuser generalized eigenmode transmission (MGET), based on the leakage-based precoding technique. A signal-to-leakage-plus-noise (SLNR) precoding scheme is one approach for linear precoding in the multiple-input multiple-output broadcast channel that sends multiple data streams to different users in the same cell. Unfortunately, SLNR-based scheme...
