摘要： The disclosed subject matter relates to energy efficiency in mobile devices associated with a wireless communications environment. Power Saving Classes (PSCs) aim to reduce the power consumption of mobile devices based on the different types of traffic. Optimizing sleep mode selection schemes so as to maximize the energy efficiency while providing a QoS guarantee can be accomplished with optimization of a theoretical framework based on the semi-Markov Decision Process along with a performance evaluation on the sleep mode operation. A novel Policy Optimization algorithm is capable of finding optimized policies for a selection of different PSCs.

摘要： Providing for cooperative sensing in wireless communications that improves user terminal throughput and minimizes interference is described herein. According to some aspects, a network entity, such as a base station, can assign a set of SUTs to measure a subset of wireless channels in a target frequency according to a cooperative sensing arrangement. In particular aspects, this assignment can be implemented so as to increase or maximize potential traffic throughput of those SUTs within the target frequency, in a given wireless time slot. In this manner, cooperative sensing can be structured so as to provide more efficient traffic communications within the target frequency.

摘要： Systems, methods, and apparatus for optimizing a use, by a secondary terminal, of an idle wireless communication channel that is associated with a primary terminal are presented herein. A mapping component can receive: information including an indication that a communication channel assigned to a wireless device is idle; and one or more requests, from respective other wireless devices, to transmit information via the communication channel. Further, an allocation component can compute power allocations of the one or more requests; and grant a request of the one or more requests based on the power allocations. The allocation component can further be configured to iteratively compute a power allocation of the power allocations based on a bandwidth allocation of the bandwidth allocations; and iteratively compute a bandwidth allocation of the bandwidth allocations based on a power allocation of the power allocations.

摘要： Providing for a cross-layer spectrum sharing model incorporating implicit power control for cognitive radio wireless communication is described herein. By way of example, a binary integer linear programming problem is formulated to establish active wireless links among secondary user nodes in a cognitive radio, ad-hoc network. The formulation reuses wireless channels among multiple activated links within disclosed interference constraints, and assigns a power level for transmissions on respective links. Additionally, the formulation employs bi-directional wireless links for the ad-hoc network, improving communication within the ad-hoc network. Further, power level assignments can be predefined and implicitly embedded in the formulation to reduce complexity.
