Abstract: The present disclosure relates to an equalizer training unit for deriving equalization parameters for compensating data-dependent distortion in received samples by use of a training sequence including a sequence p>1 times and cyclically comprising N sub-sequences of respective combinations of L time-domain symbols of a modulation scheme, wherein the N sub-sequences are cyclically arranged in a selected order and such that L−1 symbols of a respective sub-sequence overlap with symbols in the preceding and following sub-sequences. The present disclosure further relates to a training sequence generator unit for generative the training sequence and an equalizer employing the equalizer training unit.

Abstract: Systems, methods, apparatuses, and computer program products for packet latency reduction in mobile radio access networks. One method may include, when a buffer of a first sublayer of a wireless access link is empty and there is a new data unit in the first sublayer or when the first sublayer buffer is not empty and a data unit leaves a second sublayer buffer, comparing the number of data units currently stored in the second sublayer buffer with a queue length threshold that defines a total amount of space in the second sublayer buffer. When the number of data units currently stored in the second sublayer buffer is less than the queue length threshold, the method may also include transferring the data unit from the first sublayer to the second sublayer.

Abstract: Cognitive functions in a network, each comprising a learning module adapted to observe characteristics of the network and an inference module adapted to conclude, from the characteristics observed by the learning module, on a behavior of the network resulting from the observed characteristics, are controlled by halting and/or restarting operation of the learning module of a cognitive function of the cognitive functions, where operation of the inference module of the cognitive function is controlled independently from the halting and/or restarting the operation of the learning module of the cognitive function.

Abstract: A method, apparatus and computer program product are provided disable one or more antennas of an antenna array in order to achieve a predefined objective while selectively utilizing the remainder of the antennas of the antenna array. The one or more antennas to be disabled are selected in a manner to avoid appreciable impact to the fidelity of the resulting array radiation pattern. For example, the method, apparatus and computer program product may disable certain antenna elements based upon the distance of the antenna elements from a predefined location relative to the antenna array, such as the distance from the center of the antenna array, and may selectively utilize the remainder of the antenna elements such that an active portion of the antenna array approximates a circular array which results in an array radiation pattern for which the fidelity is maintained.

Abstract: An OVNA system employing an array of reference delays to estimate distance-variant phase distortion in probe light during an optical-frequency sweep thereof. The estimated distance-variant phase distortion is then used to perform a phase correction for the digital electrical signals generated in response to the probe light being passed through a device under test (DUT) during the same optical-frequency sweep. Advantageously, the performed phase correction enables the OVNA system to provide a more-accurate determination of certain optical characteristics of the DUT than that achievable without such phase correction.

Abstract: Systems and methods for sharing radio resources on an air interface. One embodiment comprises an access network element (e.g., base station) that stores a plurality of sharing patterns each comprising a different mapping of the radio resources on a physical layer of the air interface between Machine-Type Communications (MTC) and non-MTC. The access network element identifies a resource sharing window, receives input indicating conditions in the access network, selects a sharing pattern from the plurality of sharing patterns in the pattern database for the resource sharing window based on the conditions in the access network, schedules MTC transmissions on the air interface at a beginning of the resource sharing window based on the sharing pattern, and schedules non-MTC transmissions on the air interface at the beginning of the resource sharing window based on the sharing pattern.

Abstract: The method includes receiving, at a first optical communication device, feedback information on training of a neural network from at least one second optical communication device, the neural network configured to process a signal received from the first optical communication device, the feedback information at least including a training performance indication for training of the neural network conducted at the at least one second optical communication device; updating, based on the feedback information, a first initial parameter value set for the neural network maintained at the first optical communication device, to obtain a second initial parameter value set for the neural network; and transmitting the second initial parameter value set to at least one further second optical communication device, for training of the neural network to be conducted at the at least one further second optical communication device based on the second initial parameter value set.

Abstract: Various communication systems may benefit from an improved signaling protocol. For example, machine-to-machine communications in a network may benefit from improved signaling and security. A method includes establishing a secure data transmission path for an application. The secure data transmission path is used to transmit data between a user equipment and a network element. The network entity includes a gateway or an application server. The method also includes transmitting data for the application over the secure data transmission path using a pre-configured radio bearer. The radio bearer is pre-configured for data transmission between the user equipment and an access node located between the user equipment and the network element. In addition, the method includes receiving a response message at the user equipment from the network element through the secure data transmission path.
