We consider networks that use Cooperative Network Coding (CNC), which is a synergistic combination of Cooperative Communications and Network Coding. Our approach is to optimize and balance the use of forward error control, error detection, and retransmissions at the packet level for these networks. Additionally, we introduce Cooperative Diversity Coding (CDC), which is a novel means to code the information packets, with the aim of minimizing the energy consumed for coding operations. The performance of CDC is similar to CNC in terms of the probability of successful reception at the destination and expected number of correctly received information packets at the destination. However, CDC requires less energy at the source node because of its implementation simplicity. Achieving minimal energy consumption, with the required level of reliability is critical for the optimum functioning of many wireless sensor and body area networks. For representative applications, the optimized CDC or CNC network achieves ≥ 25% energy savings compared to the baseline CNC scheme.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125487302","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}

Voice services over Adaptive Multi-user channels on One Slot (VAMOS) is a feature introduced by 3GPP to efficiently utilize the available spectrum by multiplexing two voice users in the same radio resource. In VAMOS, the multiplexed users are assigned different transmit powers and allocated on either of the quadrature sub-channels. Neither the information about the sub-channel power imbalance ratio nor the sub-channel allocated is explicitly transmitted, making the design of a low-complexity single antenna VAMOS receiver to be a significant challenge. In this paper, we propose a low-complexity multi-user detection based VAMOS receiver for power constrained single antenna handsets which meets all the test requirements for both VAMOS levels I and II specified by 3GPP. We compare our algorithm with a Mono Interference Cancellation based VAMOS receiver and show that the performance of the proposed algorithm is up to >4dB higher at 3GPP specified Carrier-to-interference ratios. The work in this paper is of importance in the design of a low-complexity VAMOS receiver which is suitable for both VAMOS I and II.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"267 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114000722","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}

The device can return to a communication state without necessarily requiring RRC connection setup procedures. It is expected that with such an approach the sporadic higher level control plane signaling could be avoided when there are large amount of MTC devices which initiate packet transmissions periodically. Further it is expected that UE power consumption would be reduced. Simulation was done in a 3GPP Case 1 scenario. A simple intermittent traffic, 6 UEs per cell and a fixed long DRX parameter were in use in the evaluation. Different RRC release timer values were assumed to simulate different RRC connection states. The results show that with this approach both signaling load and energy consumption can be improved as it can avoid frequent transition in RRC-CONNECTED and RRC-IDLE states in device. For example, at a RRC release timer of 5 seconds, geometrically distribution of mean inter-burst arrival time of 30 seconds, the relative signaling load is 5.6 times less and the energy consumption in UE is about 3 times better with than without a RRC-SEMICONNECTED state.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114070182","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 optimization problem for the model described in the paper is formulated which turns out to be a Mixed Integer Non-Linear Program. Due to its high complexity, we use Lagrangian relaxation to dualize some constraint sets. The Lagrangian relaxed problem is then decomposed into two Lagrangian subproblems, one is a binary knapsack Lagrangian subproblem (BKLSP) and the other is continuous knapsack Lagrangian subproblem (CKLSP). The BKLSP is responsible for the assignment of the OFDMA subchannels and time slots to multicast sessions as well as user assignment to the multicast groups in a particular frame. The CKLSP is responsible for HAP power allocation to multicast sessions in the HAP service area. The two subproblems can be solved iteratively in search for a better solution, if there is any, for the Lagrangian problem. For the BKLSP we use two different solution algorithms, one based on dynamic programming and the other is a greedy algorithm. A greedy algorithm is also used for the CKLSP. The entire approach can be used to obtain bounds in a branch and bound algorithm for each of its nodes.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473974","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}
