Abstract: A method performed by a method performed by a network node for performing admission control in a wireless communications network is provided. The network node serves a first and one or more second UEs. The network node receives (201) from the first UE, an access request for a radio resource for communication between the first UE and the network node. The network node further estimates (203) a first prediction of a requirement of the radio resource related to the access request, based on a measured initial data traffic between the network node and the first UE. The network node determines (205) a first threshold related to the first prediction, as a function of a measured data traffic load between the network node and the one or more second UEs. The network node then performs (206) admission control by deciding whether or not to admit the radio resource to the first UE, based on whether or not the first prediction exceeds the first threshold.

Abstract: A framework for transfer learning for radio resource management-related tasks in radio access networks is defined in terms of functional entities of the network operator and associated signaling. A source learner (110) provides parameters or policies that incorporate knowledge related to another context than the actual context in which the RRM-related task is to be executed. A target learner (120) converts the source policies and parameters into models or target policies relevant to the actual context of the RRM-related task. An actor (130) receiving target learner's output is enabled to determine an RRM-related action for accomplishing the RRM-related task.

Abstract: A method performed by a network node for performing Congestion Control in a wireless communications network is provided. The network node serves a number of User Equipments, UEs, comprising a first and one or more second UEs. The first UE has a radio resource allocated for communication between the first UE and the network node. The network node estimates (203) a first prediction of a forthcoming usage of the allocated radio resource, based on a measured data traffic between the network node and the first UE. The network node further determines (205) a first threshold related to the first prediction, as a function of a measured data traffic load between the network node and the number of UEs. The network node then performs (206) congestion control by deciding whether or not to initiate a removal of the radio resource allocated to the first UE, based on whether or not the first prediction exceeds the first threshold.

Abstract: A framework for inductive tasks in RANs includes a source learner, a target learner and an inference entity that can be merged into existing or future RAN functions. The signaling mechanism between different framework entities may also be merged into existing or future network interfaces. The framework can be reused by multiple inductive tasks to perform a variety of tasks such as prediction of some network phenomena or to improve certain KPIs in the network.

Abstract: A method performed by a network node for managing a radio resource between the network node and a first User Equipment, in a wireless communications network is provided. The network node serves a number of UEs, comprising the first UE and one or more second UEs. The first UE has a radio resource allocated for communication between the first UE and the network node. The network node estimates (203) a prediction of a forthcoming empty data flow related to the allocated radio resource, based on a measured data flow between the network node and the first UE. The network node further determines (205) a threshold related to the prediction, based on a measured data flow between the network node and the number of UEs. The network node then decides (206) whether or not to initiate a removal of the radio resource allocated to the first UE based on whether or not the prediction exceeds the threshold.

Abstract: The embodiments herein relate to a method in a network node (101) for handling states associated with a wireless device (105) in a communications network (100). The network node (101) is connected to the wireless device (105) over a communications link (110). The communications link (110) is in a current state. The network node (101) receives, from the wireless device (105) information related to a data activity in the wireless device (105). The received information comprises at least information other than a current amount of data associated with the data activity. Based on the received information, the network node (101) determines a change associated with the current state.

Abstract: A wireless communication network improves reverse link communication performance by changing one or more Automatic Repeat Request (ARQ) control settings as a function of measured or estimated reverse link loading. Control settings can be changed on a per-sector basis, allowing consideration of different loading conditions in different radio sectors of the network. Further, control settings can be changed for individual mobile stations, or selected groups of mobile stations, allowing different ARQ controls to be used for different mobile stations. By way of non-limiting example, a control circuit in a base station controller can be configured to take advantage of light reverse link loading conditions in a given radio sector by changing the ARQ control parameter(s) used for one or more mobile stations operating in that sector so that fewer ARQ retransmissions are required for those mobile stations to transmit reverse link data to the network.

Abstract: A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

Abstract: An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

Abstract: A wireless communication network reduces its signaling overhead by recognizing when a mobile station transitions from an inactive state, such as Control Hold or quasi-active, back to an active state. Based on such recognition by the network, the mobile station begins sending desired traffic data without need for explicitly negotiating its return to active state, thereby reducing or eliminating higher-layer signaling, e.g., Layer 3 and above, that is otherwise required for return to active state operations. The network might further avoid explicit signaling by, for example, using transmitted reverse link Power Control Bits to indicate that an inactive mobile station should remain inactive. In this manner, inactive mobile stations may be allowed to return to active state without explicit signaling where appropriate, or held in the inactive state if needed, all without need for explicit network signaling.

Abstract: The present invention relates to the reuse of a control channel in a distributed cellular radio communication system. At least one physical channel, the so called physical control channel, in the radio communication system is used for transferring logical control channels. According to the present invention the physical uplink control channel can be reused with respect to logical control channels comprising an access request. The physical downlink control channel can be reused with respect to logical control channels comprising a message that access is granted to a mobile station or a message that someone requests contact with a mobile station. According to the invention the physical uplink control channel and/or the physical downlink control channel is reused. This means that more connections per time unit may be established in the radio communication system.

Abstract: In a radiotelephone network, processing steps previously applied to digital voice transmissions received by a regional radio transmitter/receiver but not applied to analog voice transmissions received by the transmitter/receiver are applied to such analog voice transmissions at the transmitter/receiver itself such that analog voice transmissions and digital voice transmissions may be transmitted identically between the regional radio transmitter/receiver and a regional switching center. In particular, a digital speech encoder/compressor and a corresponding digital speech decoder/decompressor (together referred to as a codec) provided at remote transmitter/receivers and the regional switching center are also provided at the regional radio transmitter/receiver so as to apply the same processing to analog voice transmissions received from the remote transmitter/receivers as is applied to digital voice transmissions at the remote transmitter/receivers.
