Abstract: A method and apparatus for processing of signals in a point-to-multipoint (P2MP) network are provided. The processing includes obtaining link conditions, in a spectrum comprising multiple OFDM subcarriers, of a plurality of users at respective user nodes that are in communication with a central node of the network. The processing further includes inputting the link conditions to an entropy loading (EL) algorithm, thereby to determine a modulation format for each of the OFDM subcarriers; optimizing an allocation of OFDM subcarriers to users according to an OFDMA scheme; and for each user, loading data from a bitstream onto the allocated OFDM subcarriers in the respective determined modulation formats.

One method includes receiving a request, from one or more radio access network optimization services, that comprises a list of attributes corresponding to characteristics of a cell and a cell selection criterion for each of the attributes, receiving, from one or more radio access network cells, a data stream comprising metrics for at least one of the cell or users in the cell. The method may also include generating, based on the received request and the metrics, a list of zero or more cells that meet the selection criterion for one of the radio access network optimization services or for a group of the radio access network optimization services, and sending, to a respective one of said one or more radio access network optimization services, the generated list of said zero or more cells that meets the selection criterion for the respective one or more radio access network optimization services.

Abstract: According to an example embodiment, a radio transmitter includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the radio transmitter to obtain bits to be transmitted; map the bits into a symbol grid in time-frequency domain; modulate the symbol grid into a first time-domain waveform; input the first time-domain waveform into a machine learning model, producing a second time-domain waveform; power amplify the second time-domain waveform, producing an amplified time-domain waveform; and transmit the amplified time-domain waveform. A radio transmitter, a method and a computer program product are disclosed.

Abstract: A method and apparatus are provided for compensating incoming signals in a receiver of an optical fiber communication system for degradation due to nonlinear optical effects in the transmission channel. The compensation is performed, inter alia, in circuitry to compute perturbation terms that are representative of predicted optical nonlinearity of the transmission channel, and circuitry to combine the perturbation terms with soft data symbols obtained from an input signal stream. The computation of the perturbation terms involves circuitry for converting an input stream of soft data symbols to an input stream of hard data symbols, and then operating on the input stream of hard data symbols according to a model of nonlinear effects in the transmission channel.

Abstract: Embodiments of the present disclosure relate to cell selection in a multiple frequencies communication network. A network device receives, from terminal devices, signal reception quality measurements for a set of cells at serving frequencies of the network device. The network device updates, based on the measurements, serving cells in the set for the terminal devices in such a way that a total throughput of the network device is maximized and a cell edge throughput of the network device exceeds a threshold throughput. The network device transmits information about the updated serving cells to the terminal devices for access by the terminal devices.

Abstract: A first router determines a designated router (DR) from a set of routers that are interconnected by a network based on a border gateway protocol (BGP). The set includes the first router. In response to the first router being the DR, the first router forms adjacencies with non-DR routers from the set and distributes reachability advertisements from the set of routers to the non-DR routers in the set. In response to the first router not being the DR, the first router forms an adjacency with the DR. The first router then conveys reachability advertisements to the DR and receives reachability advertisements from the routers in the set via the DR. The DR is determined based on receiving information at the first router indicating an identity of the DR, e.g., configuration information received from a controller, or by electing a DR based on priority values assigned to the routers and advertised in messages transmitted by the routers.

Abstract: Various example embodiments relate to power saving in a wireless communication network and, in particular, an apparatus and a method to determine a threshold to establish whether a cell of a group of cells supporting network coverage in an area of a wireless communication network should enter or exit a power saving mode.
