Semi-Decentralized Interference Aware Scheduling in D2D-Enabled Cellular Networks

“…A series of works deal with interference management for D2D links [9]- [25], each of which targets a slightly different system model or problem target. For example, the works differ in whether downlink bands [11], [19] or uplink bands [9], [10], [12]- [18], [20]- [25] are considered, in whether fixed transmission powers are assumed [9], [12], [13], [22]- [24] or power control is part of the optimization [10], [11], [14]- [21], [25], whether frequency reuse is constrained to one-fold reuse by D2D links [9]- [11], [14], [18], [20], [25] or multiple D2D links may use the same frequency [12], [13], [15]- [17], [19], [21]- [24], or in the optimization target, which typically is assumed to be the sum-rate [9], [10], [12], [13], [16]- [23], [25] but can also be proportional fair rate [24], a general utility [11] or just the satisfaction of rate constraints [15]. Due to the complexity of the considered problem, various solutions have been proposed, each tailored to a...…”

Resource Allocation with a Rate Guarantee Constraint in Device-to-Device Underlaid Cellular Networks

“…In addition, a DU is allowed to be assigned to multiple channels in [15][16][17]. In addition to power control and resource allocation, mode selection for DUs and relay selections were considered in [18][19][20] and [21,22], respectively. In the above-mentioned studies, a fixed channel bandwidth is allocated to each channel and moreover, a channel is pre-assigned to a CU in advance, and hence, the remaining channel assignment problem is to choose the best DU for each CU.…”

“…In most previous sum rate or energy efficiency maximization schemes [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], even though SINR or minimum data rate per UE was considered as a constraint, the individual data rate may not be guaranteed with a fixed amount of channel bandwidth. When the received SINR is low due to high interference and maximum transmit power limitation, the fixed channel bandwidth may not be wide enough to guarantee the target rate.…”

A Novel Access Control and Energy-Saving Resource Allocation Scheme for D2D Communication in 5G Networks

“…e NP-hard joint resource allocation problem was formulated as a oneto-one matching problem, which also did not consider access control problem of D2D links [15]. A signal to interference plus noise ratio (SINR) aware mode selection, scheduling, and resource allocation scheme for D2D communications was put forward by Bithas et al [16]. However, scheduling and resource allocation were considered individually.…”

“…Although some current works [6,7,16,20,21] considered access control and resource allocation, access control and resource allocation were optimized individually. Firstly, they determined whether a D2D pair can be admitted under the SINR requirements of both D2D users and cellular users.…”
