Millimeter wave (mmWave) communication has been a promising technology of future fifth generation (5G) cellular networks. Due to the tremendous propagation loss of mmWave communication, device-to-device (D2D) communications are widely used over directional mmWave networks to improve the network throughput. In this paper, a new time resource sharing scheme is proposed based on Stackelberg game for...
With the increasing demand for higher performance wireless local area networks (WLANs), channel bonding was first proposed in the IEEE 802.11n protocol to offer a higher data rate by combining two 20 MHz channels into one 40 MHz channel. Although much has been understood about channel bonding management, hardly any of these innovations have made it into today's IEEE 802.11 WLANs in a distributed manner...
Previous work on 802.1 1x (Wi-Fi) power control have focused almost exclusively on the mitigation of interference from data frames. Since Wi-Fi wireless access points are increasingly ubiquitous, it is now common for an 802.1 1x client to be able to receive signals from more than 10 APs simultaneously in a modern urban operating environment. At such high densities, we found that the interference from...
This paper considers the problem of adjacent channel interference between two different operators using different duplexing methods. Focusing on the interference between two co-located base stations, which existing guard-band based methods still cannot solve efficiently, we propose a scheme that adjusts the downlink power of the aggressor system to maximize the downlink transmission capacity while...
This paper investigates the resource allocation problem in a relay-aided cognitive radio (CR) system under the orthogonal frequency division multiplexing (OFDM) transmission. Different from the conventional CR resource allocation problem, the relay node here is capable of performing subcarrier permutation over two hops such that the signal received over a particular subcarrier is forwarded on a different...
Multicast support is critical and a desirable feature of multi-radio wireless mesh networks. However, the nature of wireless network, i.e. broadcasting and interference, makes it a challenge to efficiently support multicast services. In this paper, we study how to build a multicast structure with maximum average throughput in terms of minimum transmission time and channel interference in a multi-radio...
In the relay-enhanced cellular network, the target user will receive uncertain interference due to orthogonal transmission between BS and RS, which would make the traditional mechanisms of link adaptation and channel-aware scheduling invalid. In this paper, a novel resource scheduling scheme is proposed with a semi-static mode, in which dominant interferences for a target user are identified and inter-cell...
Cognitive radio makes it possible for an unlicensed user to access a licensed spectrum opportunistically on the basis of non-interfering. This paper addresses the problem of resource allocation for multiaccess channel (MAC) of OFDMA-based cognitive radio networks, taking into account of the interference temperature constraints. The objective is to maximize the system utility, which is used to quantify...
