VI Adaptive Communications for Next Generation Broadband Wireless Access Systems VII Abstract In Broadband Wireless Access systems the efficient use of the resources is crucial from many points of views. From the operator point of view, the bandwidth is a scarce, valuable, and expensive resource which must be exploited in an efficient manner while the Quality of Service (QoS) provided to the users is guaranteed. On the other hand, a tight delay and link quality constraints are imposed on each data flow hence the user experiences the same quality as in fixed networks. During the last few years many techniques have been developed in order to increase the spectral efficiency and the throughput. Among them, the use of multiple antennas at the transmitter and the receiver (exploiting spatial multiplexing) with the joint optimization of the medium access control layer and the physical layer parameters. In this Ph.D. thesis, different adaptive techniques for B3G multicarrier wireless systems are developed and proposed focusing on the SS-MC-MA and the OFDM(A) (IEEE 802.16a/e/m standards) communication schemes. The research lines emphasize into the adaptation of the transmission having (Partial) knowledge of the Channel State Information for both; single antenna and multiple antenna links. For single antenna links, the implementation of a joint resource allocation and scheduling strategies by including adaptive modulation and coding is investigated. A low complexity resource allocation and scheduling algorithm is proposed with the objective to cope with real- and/or non-real- time requirements and constraints. A special attention is also devoted in reducing the required signalling both in the downlink and the uplink. Moreover, for multiple antenna links, the performance of a proposed adaptive transmit antenna selection scheme jointly with space-time block coding selection is investigated and compared with conventional structures. In this research line, mainly two optimizations criteria are proposed for spatial link adaptation, one based on the minimum error rate for fixed throughput, and the second focused on the maximisation of the rate for fixed error rate. Finally, some indications are given on how to include the spatial adaptation into the investigated and proposed resource allocation and scheduling process developed for single antenna transmission.

    Orthogonal Frequency Division Multiple Access : Is it the Multiple Access System of the Future? Srikanth S., Kumaran V. , Manikandan C., Murugesapandian AU-KBC Research center, Anna University, Chennai, India Email: [email protected] Abstract There is significant interest worldwide in the development of technologies for broadband cellular wireless (BCW) systems. One of the key technologies which is becoming the de- facto technology for use in BCW systems is the orthogonal frequency division multiple access (OFDMA) scheme. In this tutorial article, we discuss the reasons for the popularity of OFDMA and outline some of the important concepts which are used in OFDMA as applied to BCW systems. We shall use the IEEE 802.16 based WiMAX standards for highlighting some of the significant ideas in the practical use of OFDMA systems. 1. Introduction Broadband Cellular Wireless (BCW) systems are expected to be rolled out in the near future to satisfy demands from various segments. As demand for mobile services continuous to grow worldwide system vendors and cellular operators have noticed the enormous popularity of 2nd generation mobile cellular systems and are keen to extend this trend to BCW systems. Several challenges exist in the development and deployment of BCW systems and research work addressing these challenges is ongoing in several labs around the world. The orthogonal frequency division multiple access (OFDMA) based systems are being adopted for use in different flavors of BCW systems [1]. The IEEE 802.16d and 802.16e standards which are popularly known by the industry forum name WiMAX are being considered for BCW systems and are the first standards to use the OFDMA technique [2].

In short, deploying 802.11ax-based spectrum into time-frequency resource units (RUs). In this paper, we aim at designing an 802.11ax-based dense WiFi network dense WiFi network is both crucial and urgent. There are two to provide WiFi services to a large number of users within a main factors that affect the network performance. The first given area with the following objectives: (1) to minimize the one is the AP placement. The second one is resource (such as number of access points (APs); (2) to fulfil the users’ throughput power, channel, and RU, etc.) assignment for the APs/stations. requirement; and (3) to be resistant to AP failures. We formulate Furthermore, users demand continuous WiFi services even the above into a joint AP placement and power-channel-RU assignment optimization problem, which is NP-hard. To tackle under AP’s failures [4]. Unfortunately, there is little research this problem, we first derive an analytical model to estimate each on joint AP placement and resource assignment for 802.11ax- user’s throughput under the mechanism of OFDMA and a widely based dense WiFi network with quality of service (QoS) used interference model.

In industrial net- works, manufacturing processes require hard real-time communication where the latency is less than 1ms. Time-sensitive networking (TSN) technology over Ethernet already supports deterministic de- livery for real-time communication. However, TSN technologies over wireless networks are currently in their initial development stage. Therefore, this study presents an overview of TSN research trends in wireless communications. This paper focuses on 5G networks and IEEE 802.11. We summarize standardization trends for TSN in 5G networks and introduce the TSN technologies for 802.11-based WLAN. Then, we introduce the integration scenario of 5GS with WLAN. This study provides insights into wireless communication technologies for wireless TSN.

ABSTRACT A revolutionary effort to seek fundamental improvement of 802.11, known as IEEE 802.11ax, has been approved to deliver the next-generation wireless local area network (WLAN) technologies. In WLANs, medium access control protocol is the key component that enables efficient sharing the common radio channel while satisfying the quality of service (QoS) requirements for multimedia applications. With the new physical layer design and subsequent new medium access control functions under more demands on QoS and user experience, in this paper, we first survey the QoS support in legacy 802.11. Then, we summarize the IEEE 802.11ax standardization activities in progress and present an overview of current perspectives and expected features on medium access control protocol design to better support QoS and user experience in 802.11ax.
