Abstract: In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes, by a relay node, including additional information in a failure occurrence notification indicating occurrence of a failure in a first backhaul link between a first parent node and the relay node, and transmitting the additional information to a child node. The communication control method includes receiving, by the child node, the failure occurrence notification including the additional information. Here, the additional information includes a first BAP routing ID unavailable due to the failure and/or a first destination BAP address included in the first BAP routing ID, and includes identification information indicating that the additional information includes the BAP routing ID and/or the first destination BAP address.

Abstract: Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. A power management component in a system may be configured to obtain measurements associated with a signal path used for communication by the system via a communication port, and manage power use in the system based on the obtained measurement. Managing the power use may include determining, based on the obtained measurements, connectivity related information associated with connectivity of the system via the communication port, and applying based on the information one or more power use reduction measures, with the one or more power use reduction measures including at least transitioning between different power related states.

Abstract: An EVM measurement value is appropriately determined while CPE/ICI correction is taken into account. In a measurement apparatus (300), an EVM measurer (305) measures a modulation quality of a signal transmitted from a transmission apparatus. An EVM determiner (306) determines whether or not the measurement value of the modulation quality is equal to or less than a first requirement value, in a case where correction relating to a phase noise of the transmission apparatus is necessary in a reception apparatus. The first requirement value herein is higher than a second requirement value used in the determination of the measurement value in a case where the correction relating to the phase noise of the transmission apparatus is unnecessary in the reception apparatus.

Abstract: An apparatus and method: access repeated copies of an OFDM output signal produced by a device in response to corresponding repeated copies of an OFDM input signal; for each copy of the OFDM output signal, time align the OFDM output symbols to the OFDM input symbols, and de-rotate a phase of the OFDM output signal with respect to the OFDM input signal; coherently sum and average the copies of the OFDM output signal; determine a variance of each copy of the OFDM output signal, and an ensemble variance of all of the copies of the OFDM output signal; discard copies of the OFDM output signal whose variance differs from the ensemble variance by more than a threshold amount to produce a qualified set of copies; determine a mean value of the qualified set of copies; and determine a total noise power of the qualified set of copies from the mean value.

Abstract: Accordingly, there is provided an IMS node, comprising a transmission module and a processor. The transmission module is arranged to send SIP messages to a plurality of other IMS nodes. The processor arranged to detect an error in a particular other IMS node, the error indicating that the particular other IMS node is not available to receive traffic. In response to detection of such an error, the processor causes the particular other IMS node not to be used for a period of time. The transmission module is further arranged to send at least one test message to the particular other IMS node when the period of time expires. The processor is further arranged to determine if the at least one test message is successfully processed by the particular other IMS node, and in response to a positive determination then returning the particular other IMS node to use.

Abstract: A method is disclosed for detecting ground faults in a communications system. The method includes measuring a predetermined number of voltage points; determining if the measured voltage points represent recessive or dominant bits; identifying which of the predetermined number of voltage points represent inter-frame bits and which represent frame data bits based on whether the measured voltage points are recessive or dominant; calculating a maximum average voltage for the inter-frame bits; calculating an average frame voltage for all dominant bits within a frame; determining a high average dominant voltage count based on a number of frames for which the average frame voltage is greater than a high voltage threshold; and determining if a ground fault exists based on the average frame voltage and the high average dominant voltage count.
