Abstract: Increasing capacity demands in emerging wireless technologies are expected to be met by network densification and spectrum bands open to multiple technologies. These will, in turn, increase the level of interference and also result in more complex inter-technology interactions, which will need to be managed through spectrum sharing mechanisms. Consequently, novel spectrum sharing mechanisms should be designed to allow spectrum access for multiple technologies, while efficiently utilizing the spectrum resources… Show more

“…The performance of the proposed scheme is compared with three other schemes, such as the conventional EFA and AFA schemes and the AFA2 scheme. Here, the AFA2 scheme adaptively allocates the feedback bits to PUs according to (12) in Section 2.3. Table 1 summarizes the feedback bits allocation strategy.…”

“…However, the work of [5,7] assumed the perfect CDI at the ST for using the transmit beamforming vector. Other researchers of [4,[9][10][11][12] have endeavored to increase the sum rate of SUs in the CR network with the limited number of feedback bits. However, they failed to provide the guaranteed bit rate (GBR) services for SUs.…”

“…Existing works on LTE/Wi-Fi coexistence mainly focus on optimizing LBT channel access [7], designing of collision detection schemes [8], [9], optimizing the resource allocation among MNOs [10]- [12], detecting misbehaving of LTE/Wi-Fi [13]. Detailed surveys are given in [14], [15], [16]. On the other side, several works focused on extending Wi-Fioriented Bianchi's approach into modeling LTE/Wi-Fi coexistence [17]- [24].…”

“…To deal with growing traffic demands, many studies have focused on the dynamic spectrum sharing (DSS) environment, where a spectrum is shared by various wireless technologies or multiple mobile network operators (MNO) [1]. For example, long-term evolution (LTE) and new radio (NR) standards have been proposed to operate in the 5-GHz unlicensed band, and the concept of licensed shared access (LSA) is currently being developed with the aim of enabling cellular operators to access further spectral resources on a licensed shared basis [2].…”

“…For example, long-term evolution (LTE) and new radio (NR) standards have been proposed to operate in the 5-GHz unlicensed band, and the concept of licensed shared access (LSA) is currently being developed with the aim of enabling cellular operators to access further spectral resources on a licensed shared basis [2]. One example is the 3.5-GHz Citizens Broadband Radio Service (CBRS) band under discussion [1]. As these trends eventually lead to extreme densification of various types of systems, a new DSS mechanism is needed to increase bandwidth efficiency even in extreme densification of multiple wireless technologies.…”
