Abstract: An overmoded distributed interaction network is provided that generates high peak and average RF power amplification at high frequencies. A series of overmoded cavities are bounded by parallel or concentric grids that may be separated by metallic spacers adapted to function as a photonic bandgap circuit to suppress competing electromagnetic modes. The selected electromagnetic modes have wavelengths much shorter than the lateral dimension of the grids, allowing the beam-wave interaction to be distributed transversely for improved interaction efficiency. The grids may optionally be slotted and arranged to provide a serpentine traveling wave tube configuration.

Abstract: A computer estimates multiple angles of arrival of a target signal received by an array of commutated antenna elements. In one aspect, samples of a received target signal obtained from an array of communicated antenna elements and from an element in an array of reference antenna elements are processed to make maximum-likelihood-estimations of multiple angles of arrival at which signals are received by the array of commutated antenna elements; and a display is mapped over time and frequency of the estimations, with the angle of arrival for a particular sample being represented by a variable given display feature.

Abstract: A method in a first radio network node for testing a transmission parameter value in a wireless communication system is provided. The first radio network node is configured to, during operational mode thereof, perform transmissions using available resources divided in to resource blocks. The first radio network node allocates a test resource block, for test purposes, among the available resources. The first radio network node defines for the test resource block, a test value for the transmission parameter. The test value differs from the nominal value. The first radio network node performs, during operational mode, a test transmission using the resource block. During the test transmission, the transmission parameter is set to the test value. The test transmission is configured to form the basis for an evaluation of the test value.

Abstract: The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.

Abstract: The present invention relates to a method and an arrangement for the power management of a digital communication line such as a digital subscriber line DSL (2201). A problem addressed by the invention is that the transitioning of the digital subscriber line (2201) from a low transmission power state to a high transmission power state can cause disturbance to adjacent lines. This problem is solved by the current invention by an access node AN (2100) that is arranged to step-wise increase the power state until the high transmission power state has been reached. The invention also comprises embodiments of monitoring and detecting traffic events that serve as triggers of the transitioning.

Abstract: The present disclosure relates to compensation for Passive Intermodulation (PIM) distortion in a receiver. In one embodiment, a communication device includes a transmitter that is configured to receive a digital input signal and output a radio frequency transmit signal, a main receiver configured to receive a radio frequency receive signal and output a digital output signal, and a PIM compensation subsystem. The radio frequency receive signal includes PIM distortion that is a non-linear function of the radio frequency transmit signal output by the transmitter. In order to compensate for the PIM distortion, a PIM compensation subsystem receives the digital input signal of the transmitter, generates a digital PIM estimate signal that is an estimate of the PIM distortion in the digital output signal of the main receiver, and subtracts the digital PIM estimate signal from the digital output signal of the main receiver.

Abstract: A stopping criterion for a turbo-coding method. The criterion is based on states of a trellis determined by forward-backward recursion. If, for at least one elementary decoding stage, a transition ending state of a previous symbol is found identical to a transition starting state of a current symbol, for every symbol of the block but a first one and a last one, the decoding path is considered as consistent, a hard decision on the extrinsic information is made, and the turbo-decoding stops.

Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F—PUCCH(F)—are also provided for use with PUCCH format 3.

Abstract: A method and a radio node (RN) shared by operators of separate cellular networks having operator specific tracking area plans. The radio node (RN) broadcasts (1:1) system information with network identities of the cellular networks (PLMN IDs) and multiple operator specific tracking area codes (TACs) valid in respective tracking area plans of the cellular networks, each tracking area code being associated with a corresponding network identity in the system information. Thereby, the operators are enabled to use their own operator specific tracking area codes for their respective operator specific tracking areas that include a cell (100) covered by the radio node.
