Abstract: A method in a first user equipment (UE 1) connectable to a second user equipment (UE 2) via a communication network or via a direct radio communication link, of using a direct radio communication link for communication between the UEs is initiated when one of the UEs receives probe signaling information comprising a first probe token via the communication network. The UEs exchange probe signaling messages including a second and/or the first probe token at least partly according to the probe signaling information, such that one of the UEs can compare the probe tokens, generate a probing report and provide the probing report to the communication network, or to the opposite UE for evaluation in case of a successful comparison and such that a direct radio communication link can be used for communication with UE 2 in response to receiving instructions to use the second direct radio communication link from the entity by which the probing report was evaluated.

Abstract: Methods and arrangements for use in a respective node and mobile terminal in a first system associated with a first frequency band for radio communication, for supporting avoiding or reducing interference in a second frequency band associated with a second system, which second frequency band is adjacent to the first frequency band. The method for use in the node comprises detecting activity of the second system in the second frequency band and adjusting the bandwidth used by the node for communication, based on characteristics of the detected current activity of the second system in the second frequency band, such that interference to the second frequency band, from radio communication associated with the node, is adapted to the second system activity in said second frequency band. The method further comprises providing information of said adjustment to at least one mobile terminal. Further, information of said adjustment could be provided to neighboring nodes.

Abstract: Systems and methods for providing efficient utilization of spectrum in a cellular communication network that applies Almost Blank Subframes (ABSs) are disclosed. In general, the network includes an access node that applies ABSs in the downlink. In one embodiment, the access node identifies UEs for which transmissions are to be scheduled for the uplink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs and subframes in the uplink that correspond to at least some of the ABSs in the downlink. In another embodiment, the access node identifies UEs for which transmissions are to be scheduled for the downlink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs for the downlink and at least a subset of the ABSs in the downlink.

Abstract: A system (120) and method (135, 145) for reducing signaling overhead related to scheduling of uplink and downlink radio resources to wireless devices such as sensors or Machine-to-Machine, M2M, devices (122) that are primarily stationary in a cellular network (124). Time-frequency channel conditions have a much lower variance for these stationary devices as compared to other mobile devices in the network. Hence, the (semi)stationary channel can be estimated over time with the help of statistical methods and machine learning techniques, and stationary devices can be instructed to stop reporting uplink and/or downlink channel-related information to the network until further notice. When performance degradation is noticed by the base station (126), the scheduler (239) may instruct the device to resume its channel condition reporting. This solution also reduces the energy consumed within the stationary devices due to significant reductions in the number of channel measurements, their processing, and reporting.
