摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing do, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要： The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

摘要： A node (100; 300) of a mobile network is responsible for scheduling transmissions of data blocks between the mobile network and a terminal device (200, 200′). The node (100; 300) may for example be a base station (100) or a control node (300) of the mobile network. The node (100; 300) determines a processing time required by the terminal device (200; 200′) for processing signals for transmission of one of the data blocks. The processing time is determined from a plurality of supported processing times. On the basis of the determined processing time, the node (100; 300) schedules the transmission of the data block. The terminal device (200, 200′) may provide control data for determining the processing time to the node (100; 300).

摘要： Systems and methods are disclosed for providing energy efficient operation for wireless access nodes in a dense deployment of wireless access nodes in a cellular communication network. In one particular embodiment, wireless access nodes form a super dense network. In one embodiment, a wireless access node in a dense deployment of wireless access nodes in a cellular communication network includes a transmitter and a receiver that are operated according to a discontinuous transmit and a discontinuous receive mode of operation. The wireless access node controls one or more duty cycles for the discontinuous transmit and discontinuous receive mode of operation based on an alertness state of the wireless access node. In one embodiment, the one or more duty cycles increase as the alertness state of the wireless access node increases. In this manner, the wireless access node is operated in an energy efficient manner.

摘要： Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller (210) and radio resource manager (220). A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.
