摘要： System and method for reducing signaling overhead related to scheduling of uplink and downlink radio resources to wireless devices (e.g., sensors or Machine-to-Machine (M2M) devices) that are primarily stationary in a cellular network. Because these wireless devices are non-moving, time-frequency channel conditions have a much lower variance for them 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 then instructed to stop reporting uplink and/or downlink channel condition related information to the network until further notice. When performance degradation is noticed by the base station, the scheduler may instruct the device to resume its channel condition reporting. As a byproduct of this solution, the energy consumed within such stationary terminals is reduced due to significant reductions in the number of channel measurements, their processing, and reporting.

摘要： The dynamic determination of a handover trigger for triggering handover of a mobile terminal in a wireless network from a source base station to a target base station is based on one or more Key Performance Indicators (KPIs). Each KPI indicates a quality of wireless services provided by the wireless network responsive to a particular handover trigger. If an obtained parameter that indirectly or directly impacts handover performance passes a corresponding performance test, the mobile terminal selects the handover trigger based on the KPIs. If the parameter fails the corresponding performance test, the source base station selects the handover trigger based on the KPIs.

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 in a cellular communications network depending on mode of operation. In one embodiment, a node in the cellular communications network determines whether a wireless device (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 then applies different values for at least one parameter depending on whether the wireless device 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 when operating in the long range extension mode is substantially reduced.

摘要： Systems and methods for detecting a Line of Sight (LOS) in a cellular communications network are provided. In one embodiment, a network node in the cellular communications network determines whether a wireless device is within LOS of a base station. In order do so, the network node compares a Ricean factor of a wireless communications channel between the base station and the wireless device and a predetermined Ricean factor threshold for LOS detection. In addition, the network node compares a Root Mean Squared Error (RMSE) between a Rayleigh probability density function and samples of received signal strength for radio signals transmitted between the base station and the wireless device and a predetermined RMSE threshold for LOS detection. The network node then determines whether the wireless device is within LOS of the base station based on results of the comparisons.
