摘要： Facilitating frequency selective scheduling in advanced networks (e.g., 4G, 5G, and beyond) with multiple transmission points is provided herein. Operations of a system can comprise facilitating an activation of a frequency selective scheduling based on identification of control channel elements used for a downlink control channel. The operations also can comprise instructing a user equipment device to report a subband channel quality indicator and a subband precoding matrix index based on a result of an evaluation of a metric determined based on channel conditions. Further, the operations can comprise scheduling the user equipment device with a subband based on the subband channel quality indicator and the subband precoding matrix index reported by the user equipment device.

摘要： Detection and prevention of heavy congestion in a wireless network is disclosed herein. Radio links are monitored and if the number of radio links reaches a first threshold level, one or more network parameters are modified in order shrink a cell footprint and/or to control cell reselection. The monitored radio links can be downlink circuit switched and packet switched radio links. Alternatively or additionally, an uplink noise level can be monitored and if the uplink noise level reaches a second threshold level, the one or more network parameters can be modified, even if the number of radio links are not at the threshold level.

摘要： A system that can detect a congested network node device that is overloaded due to number of user equipment (UE) devices connected to the network node device being determined to have exceeded a connection threshold; determine a second network node device that is available to establish connections with at least some of the UEs connected to the congested network node device; identify a third network node device that is transferring UE devices to the congested network node device to create additional connections; and transmit a cell individual offset (CIO) parameter and cell hysteresis offsets to the third network node device to reduce transferring UE devices to the congested network node device, and another CIO parameter and cell hysteresis offsets to the second network node device to increase establishment of the UE connection from the congested network node device.

摘要： Adjustment of a transmit power parameter, such as a ceiling level, is disclosed. Signal-to-noise type information and committed power information can be employed to determine the ceiling level adjustment. A ceiling level can be a predetermined cap on transmission power for downlink or uplink channels between a user equipment and a base station. Where there is sufficient headroom in total transmission power and a power level greater than the predetermined ceiling can be effective, the ceiling can be adjusted to greater values than the predetermined value. Where total transmission power is more committed, ceiling adjustment can be prevented. Further, where there is no adequate benefit from increasing the ceiling, the adjustment of the ceiling can be prevented. While some instances can result in optimized transmission levels below the ceiling, instances can also be accommodated where the ceiling is to be increased.
