  • Patent number: 9961695
    Abstract: There is provided embodiments relating to scheduling in mobile communications systems, and particularly to scheduling of delay tolerant data in mobile communications systems. A scheduling request relating to conditional data transfer of delay tolerant data is received. The delay tolerant data is scheduled for transmission such that the delay tolerant data is to be transmitted in conjunction with data already scheduled for transmission and utilizing available transmission resources non-utilized for transmission of the data already scheduled for transmission.

  • Patent number: 9918327
    Abstract: A first network node of a cellular system is configured for communication with a second network node over a twisted pair wire. The first network node includes a receiver for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also includes an up-converter for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal.

  • Patent number: 9661568
    Abstract: A method is presented for adjusting power consumption in a network node of a cellular communication system. The method is performed in a power adaption device and comprises the steps of aggregating bitrates for all traffic flows associated with a power amplifier of the network node to an aggregated bitrate, determining when to adjust power consumption by determining whether power consumption of the power amplifier can be reduced with acceptable effect on the traffic flows associated with the power amplifier, and adjusting power consumption by reducing power consumption of the power amplifier when it is determined that the power consumption of the power amplifier can be reduced with acceptable effect on the traffic flows associated with the power amplifier. A corresponding power adaptation device is also presented.

  • Patent number: 9572099
    Abstract: The embodiments herein relates to a method in a first network node for handling operation mode of a base station in a communications network. The communications network comprises a transport network. The first network node activates a Remote Unit-Main Unit, RU-MU, operation mode in the base station when data traffic load in the transport network is below a first threshold. The first network node activates a regular operation mode in the base station when the data traffic load in the transport network is above a second threshold.

  • Patent number: 9521615
    Abstract: A method in a first network node (215) for handling transport network data traffic in a first base station (201) is provided. The first base station (201) comprises a transport network transmission equipment (205) and the transport network transmission equipment (205) is a part of a transport network. When the first base station (201) is in a sleep mode, the first network node (215) determines (306, 801) that the transport network transmission equipment (205) should be bypassed by activating a relay (209) comprised in the first base station (201) such that data traffic from a second network node (217) is transmitted via the relay (209) to a third network node (220).
