Abstract
LTE is marketed as 4G standard for wireless communication services. LTE network technologies provide a high speed triple play services like data, voice, and video with QoS provision. The resource allocation techniques primary concerns are the QoS support that aims to sat
Highlights
Among the versatile scenarios supported by future 5th Generation mobile communication (5G), high mobility is one of the most important and extreme use cases, which attracts much interests [1, 3]
It is presented to compete with Broadband Wireless Access (BWA) such as Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access (CDMA) and High-Speed Uplink/Downlink Packet Access (HSU/DPA)
The concept of multiuser diversity has attracted a significant consideration, as well as recognised as a key principle in developing wellorganized adaptive resource allocation algorithms for wireless communication systems [58]. This survey has provided the fundamental information about the design of traffic scheduling algorithms for BWA networks
Summary
Among the versatile scenarios supported by future 5th Generation mobile communication (5G), high mobility is one of the most important and extreme use cases, which attracts much interests [1, 3]. The standard of IEEE 802.16 defines Medium Access Control (MAC) and Physical (PHY) layers of the air interface for a Broadband Wireless Access (BWA). This paper considers the PMP mode with frame-base’s precedence of DL sub-frame over the UL sub-frame for the Downlink (DL) and Uplink (UL) transmission In this mode, BS is responsible to transmit the service to multiple Subscriber Stations (SSs) within its range as a one-hop structure. OFDMA has been adopted for various standards such as IEEE 802.11n [5] and 4G generation cellular systems such as IEEE 802.16m and 3GPP Long Term Evolution (LTE) [6]. Scheduling is the problem of determining bandwidth priority that will be given to the users This survey focuses on bandwidth scheduling algorithms for QoS provisioning in LTE networks especially in the MAC and Physical layers. In order to answer the need of QoS provisioning, this paper describes categorization of LTE QoS provisioning procedures that operate on physical and MAC layers
