Abstract

from arXiv · show

A constant need to increase the network capacity for meeting the growing demands of the subscribers has led to the evolution of cellular communication networks from the first generation (1G) to the fifth generation (5G). There will be billions of connected devices in the near future. Such a large number of connections are expected to be heterogeneous in nature, demanding higher data rates, lesser delays, enhanced system capacity and superior throughput. The available spectrum resources are limited and need to be flexibly used by the mobile network operators (MNOs) to cope with the rising demands. An emerging facilitator of the upcoming high data rate demanding next generation networks (NGNs) is device-to-device (D2D) communication. An extensive survey on device-to-device (D2D) communication has been presented in this paper, including the plus points it offers, the key open issues associated with it like peer discovery, resource allocation etc, demanding special attention of the research community, some of its integrant technologies like millimeter wave D2D (mmWave), ultra dense networks (UDNs), cognitive D2D, handover procedure in D2D and its numerous use cases. Architecture is suggested aiming to fulfill all the subscriber demands in an optimal manner. The Appendix mentions some ongoing standardization activities and research projects of D2D communication.

A. First Generation (1G) … E. Fifth Generation (5G)

Wireless generations progressed from insecure, low-rate analog 1G to digital 2G, higher-rate 3G, IP-based 4G, and technology-aggregating 5G. LTE-A introduced D2D, which can offload traffic from base stations by enabling direct device communication.

  • A. First Generation (1G): 1G, introduced in the early 1980s, used analog circuit-switched AMPS with FDM, supported up to 2.8Kbps, and had high power consumption, poor call quality, and no security.
  • B. Second Generation (2G): 2G introduced digital cellular networks such as GSM, CDMA, and IS-95, supporting up to 64kbps, email, and SMS with improved security but not complex video.

  • A. Millimeter wave D2D Communication: mmWave D2D can provide multigigabit-per-second communication across the 30GHz–300GHz band while enabling concurrent direct links and spatial reuse.Directional antennas enhance capacity and spectrum utilization, but resource sharing must account for directional interference and neighbor-discovery deafness.
  • B. Cooperative D2D Communication: Cooperative D2D communication supports distant pairs by improving data-offloading quality, reducing interference, and increasing network coverage.Cooperation is particularly relevant when the direct user link is insufficient.
  • B. Cooperative D2D Communication: Game-theoretic cooperation and cooperative multi-hop D2D can improve cooperation strategies and data rates, but the associated UE power consumption requires optimization.The survey also discusses cooperation based on social reciprocity and trust, and multi-hop cooperation.
  • C. Handover in Device-to-Device Communication: D2D mobility can require joint handover when paired devices remain nearby, half handover when only one device changes cells, or no handover.Joint handover moves all devices to the target cell, whereas half handover leaves one UE connected to the source cell.
  • C. Handover in Device-to-Device Communication: The handover decision method uses HOM, TTT, LTEth, D2Dth, and TTTD, with HOM based on the RSRP difference between source and target eNBs.The eNB makes the decision after the requisite conditions are satisfied, selecting joint, half, or no handover.

Resource allocation enables D2D links underlaying cellular communication by improving spectral efficiency, with centralized and distributed strategies offering different complexity tradeoffs. The survey reviews allocation algorithms, a throughput-maximization model, and a proposed architecture for meeting next-generation network requirements.

Power control in D2D-underlay cellular networks focuses on selecting transmission powers to mitigate near-far effects and co-channel interference, particularly for uplink transmissions. Allocating maximum power limits to D2D users helps preserve cellular-user QoS, while statistical and distributed schemes address different channel and network conditions.
