They claim to guarantee QoS support in terms of low delay and guaranteed throughput. However, with the availability of flat rate plans and bandwidth-hungry applications of future mobile devices the systems are facing a hard challenge in satisfying all demands at the same time in a traffic load situation which can best be characterized as total overload or full buffer. In this situation the basic voice service must still be operational to full Erlang capacity, no matter what load the data traffic offers. In this paper the hierarchical static priority scheduling scheme is used to accomplish the required separation. Candidate technologies like LTE-Advanced, WiMAX are based on OFDMA access which allows flexible radio resource allocation, but has an inherent near-far heterogeneity which leads to unfairness if it is optimized for spectral efficiency. Multi-hop relaying is one way to diminish the near-far problem, which is why it is an important part of the system concepts. The scheduling scheme is designed with this multihop capability in mind and results show that in heterogeneous scenarios a proportional fair substrategy achieves the desired fairness. To achieve QoS distinction a flow management must be provided in OSI layer two, so that flows of different classes can be treated separately. This paper treats the flow management concept for multi-hop mobile radio systems, a key enabling technology for QoS aware resource scheduling. It features the cross-layer signaling of QoS requirements by the Application Layer to the Data Link Layer.","PeriodicalId":417714,"journal":{"name":"2010 IEEE 72nd Vehicular Technology Conference - Fall","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130909267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An approximate analytical formulation of the saturated throughput of a cognitive IEEE 802.15.3c MAC in the directional contention access period (D-CAP) in the presence of contention time allocation period (CTAP) is presented in this paper. The analytical framework is formulated for N devices, including the pico-net controller (PNC). The state transition diagram is modeled by a two-dimensional discrete-time Markov chain. One dimension of the Markov chain is for the backoff stage and the second dimension is for the value of the backoff counter. The saturated throughput is approximated by the product of a weighted ratio of the throughput of the regular sub-CAP (RS-CAP) and the throughput of the RS-CAP minus the period necessary to transmit a packet before the end of the current RS-CAP, the probability of the number of devices in a beam sector, the number of beam sectors and the probability of false alarm. Numerical results of the saturated throughput corresponding to typical parameter values are presented. These results show the advantage of the cognitive IEEE 802.15.3c MAC in the D-CAP using the single carrier mode when the number of devices in the WPAN is large.","PeriodicalId":417714,"journal":{"name":"2010 IEEE 72nd Vehicular Technology Conference - Fall","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115675007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the performance loss caused by application of these suboptimal detectors in additive white Gaussian noise (AWGN) has not been well investigated yet. In this paper, we analyze the asymptotic bit error rate of general FS-Lp and SD-Lp detectors in independent identically distributed Rayleigh fading channels. Our results are valid for all types of noise with finite moments including AWGN. We show that both FS-Lp and SD-Lp detectors achieve a diversity gain equal to the number of receive antennas independent of the metric parameter p and the type of noise. However, except for the conventional L2 case, the performances of FS-Lp and SD-Lp detectors are not identical and the performance differences may be several dB for large numbers of receive antennas. Also, our results show that p=2 is not optimal in non-Gaussian noise and L1 and Linfty detectors may result in large performance gains or degradations compared to L2 detectors depending on the type of noise.","PeriodicalId":417714,"journal":{"name":"2010 IEEE 72nd Vehicular Technology Conference - Fall","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114314336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
