摘要： In a non-limiting and exemplary embodiment, a method is provided for adapting a device set of one or more radio devices providing detection estimates for the presence of a primary radio resource user. A first detection estimate for the presence of the user is determined on the basis of spectrum sensing. At least one other detection estimate for the presence of the user is received from the device set. A detection value is generated on the basis of the first detection estimate and the at least one other detection estimate, and the device set is adapted on the basis of the detection value.

摘要： A method for unsynchronized signaling between nodes in a network is described. The method includes partitioning a message for asynchronous transmission in a network into a plurality of symbols. A symbol includes a cyclic prefix. Causing the plurality of symbols to be transmitted (for example, via a transmitter) on one or more subcarriers allocated for asynchronous transmissions is also included in the method. A given symbol is transmitted so as to reduce a discontinuity between a previous symbol and the given symbol. The method may also include applying a phase shift to one or more symbols of the plurality of symbols. Transmitting may include transmitting at a transmission frequency, where a length of a transmission cycle is determined by the transmission frequency, and where a length of the cyclic prefix is equal to an integer number of transmission cycles. Apparatus and computer readable media are also described.

摘要： Methods and systems can provide accurate synchronization of two nodes even when those nodes cannot communicate directly with one another. A method, for example, can include determining a first propagation delay estimate to a first node (910). The method can also include determining a second propagation delay estimate to a second node (920). The method can further include receiving a first synchronization message from the first node (930). The method can additionally include transmitting a second synchronization message to the second node (940). The second synchronization message depends on the first synchronization message, the first propagation delay estimate, and the second propagation delay estimate.

摘要： A method, apparatus, and computer program is presented for use in a radio transmitter using a polar transmitter structure in which a transmission signal is separated into an amplitude component and a phase component. The transmission signal includes transmission symbols distributed to a number of transmission resource blocks allocated to the radio transmitter for transmission. The amplitude component of the transmission signal is low-pass filtered in a low-pass filter configured by filtering parameters selected according to the number of transmission resource blocks allocated to the radio transmitter. Then, the low-pass filtered amplitude component is used in power supply of a power amplifier configured to power-amplify a phase component of the transmission signal.

摘要： An apparatus, method and system to control a transmitter power level to manage interference between communication nodes in a communication system. In one embodiment, an apparatus includes a processor (520) and memory (550) including computer program code. The memory (550) and the computer program code are configured to, with the processor (520), cause the apparatus to receive an interference message including a reported interference characteristic associated with a communication resource employed by an interfered communication node and a reported weighting factor indicating an importance of the communication resource to the interfered communication node. The memory (550) and the computer program code are also configured to, with the processor (520), cause the apparatus to generate a message for a receiving communication node employing the communication resource, and select a transmitter power level for the message as a function of the reported interference characteristic and the reported weighting factor.
