“…In [1], it is proposed to decompose the uplink cell throughput into the aggregated throughput of the D2I and D2D users within the cell. Therein, a scenario with stationary users was studied in which the radio link condition does not vary significantly, and thus the overhead due to the user radio link measurement, i.e., channel state information and positioning transmission, was ignored.…”

“…In equation 2,h k andh m are the overhead due to the subgranting signaling, the positioning information and radio link measurement reports transmitted by the D2I and D2D users. In [1], it has been manifested that the user throughput is proportional to qb over the transmission time, τ where q is the Modulation and Coding Scheme (MCS), and captures the bit error rate ε. Moreover, b stands for the number of allocated RBs.…”

“…Thus a higher spectral efficiency can be achieved when the sub-granting is granted to a full buffer beneficiary user with the highest modulation coding scheme. With this aim, a new DSGRR algorithm is suggested in [1]. Therein, the Base Station (BS) as a central controller chooses a beneficiary user for every D2D user, i.e., sub-grant provider, based on some criteria and accordingly informs the sub-grant provider about the candidate beneficiary users.…”

“…The eLA is a geographical area wherein the beneficiary user can decode the sub-granting signaling reliably. In [1], a scenario where all users are stationary is considered. However, to have a precise eLA in a dynamic scenario, every entity should transmit the measurement information, e.g., positioning and Channel State Information (CSI), more frequently, which results in incurring huge overhead on the cellular network.…”

“…In this paper, we further study a new OSGRR scheme where a sub-grant provider user openly broadcasts the sub-granting resources, and all beneficiary users become involved to select the beneficiary user candidate for a specific time interval in a cooperative manner. A short and preliminary version of this work was presented in the conference publication [1]. The main contributions of this study are summarized as follows:…”

Abstract Capacity, reliability, and latency are seen as key requirements of new emerging applications, namely Vehicleto- Everthings (V2X) and Machine Type Communication (MTC) in future cellular networks. Device-to-Device (D2D) communication is envisaged to be the enabler to accomplish the requirements for the aforementioned applications. Due to the scarcity of radio resources, hierarchical radio resource allocation, namely the sub-granting scheme, has been considered for the overlay D2D communication. In this paper, we investigate the assignment of un-utilized radio resources to Device-to-Infrastructure (D2I) users, i.e., beneficiary user, for moving users in a dynamic environment. The sub-granting assignment problem is mathematically cast as the uplink cell throughput maximization problem. To this end, two heuristics are proposed: 1) Dedicated Sub-Granting Radio Resource (DSGRR) in a centralized manner, and 2) Open Sub-Granting Radio Resource (OSGRR) in a distributed fashion. Simulation results show improved cell throughput for the OSGRR compared with the DSGRR yet less overhead while having reasonable tightness to the maximum achievable uplink throughput.

Capacity, reliability, and latency are seen as key requirements of new emerging applications, namely vehicle-to-everything (V2X) and machine-type communication in future cellular networks. D2D communication is envisaged to be the enabler to accomplish the requirements for the applications as mentioned earlier. Due to the scarcity of radio resources, a hierarchical radio resource allocation, namely the sub-granting scheme, has been considered for the overlay D2D communication. In this paper, we investigate the assignment of underutilized radio resources from D2D communication to device-to-infrastructure communication, which are moving in a dynamic environment. The sub-granting assignment problem is cast as a maximization problem of the uplink cell throughput. Firstly, we evaluate the sub-granting signaling overhead due to mobility in a centralized sub-granting resource algorithm, dedicated sub-granting radio resource (DSGRR), and then a distributed heuristics algorithm, open sub-granting radio resource (OSGRR), is proposed and compared with the DSGRR algorithm and no sub-granting case. Simulation results show improved cell throughput for the OSGRR compared with other algorithms. Besides, it is observed that the overhead incurred by the OSGRR is less than the DSGRR while the achieved cell throughput is yet close to the maximum achievable uplink cell throughput.
