Delay, guaranteeing causality, is inevitable in cooperative communication systems. Traditionally, delay granularity has been limited to one symbol; however, channel delay is in fact governed by channel memory and can be shorter. For example, the delay requirement in orthogonal frequency-division multiplexing (OFDM), captured in the cyclic prefix, is typically much shorter than the OFDM symbol itself...
Sharing radio resources of multiple wireless networks with overlapped coverage areas has a potential of improving the transmission throughput. However, the improvement cannot be achieved in congestion scenarios using independent congestion control procedures among the end-to-end paths. Although various network characteristics make the congestion control complex, this variety can be useful for congestion...
The abundant bandwidth at 60 GHz band (around 7 GHz) offers the potential for multi-Gbps indoor wireless connections for bandwidth-intensive applications. However, 60 GHz millimeter wave (mmWave) links are highly susceptible to blockage since it is difficult to diffract around obstacles. In this paper, we propose multi-radio band integration framework to have 2.4/5 GHz band assist mmWave band to prevent...
