Abstract: An access node in a wireless communication network receives a transmission that includes first and second signals. The first and second signals may be layers of a multiple-input multiple-output transmission and may also be from first and second terminal nodes. The access node derives first and second local reference signals from the transmission received using first and second antennas and estimates channel transfer functions associated with the channel through with the transmission is received. Estimating the channel transfer function can include correlating at least a portion of an expected reference signal associated with the first signal with a corresponding portion of the first local reference signal and correlating at least a portion of an expected reference signal associated with the second signal with a corresponding portion of the second local reference signal. The expected reference signal portions used to estimate the channel transfer functions may be non-orthogonal.

Abstract: Systems and methods generate corrected channel transfer functions by cross-correlation nulling. In an example system, a first receiver node (which may be a wireless base station) receives first expected reference signal information associated with an interfering transmitter node (which may be a wireless user equipment) and creates a correction matrix based on the first expected reference signal information associated with the interfering transmitter node and on second expected reference signal information associated with an intended transmitter node. The correction matrix can then be applied to an estimated channel transfer function associated with a received transmission from the intended transmitter node to generate a corrected channel transfer function associated with the received transmission from the intended transmitter node. The first receiver node can use the corrected channel transfer function in decoding received transmissions including, for example, use in performing interference resolution.

Abstract: Systems and methods preserve application identification information on handover in a communication network. End user quality of experience is improved by determining applications associated with communications to and from the end user. The applications may include application classes and specific applications. The application information is used to schedule packets such that the end user quality of experience is improved for that application. When the end user is handed over between wireless access nodes, the access nodes transfer application information so that the improved end user quality of experience is maintained.

The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions.

Some embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, other embodiments provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, others provide a proactive response by discarding packets based on predicted oversubscription, and others provide a combination thereof.

Abstract: A network node, and a method for operating a network node, such as a base station, may transmit multiple video streaming sessions from servers to clients in terminal nodes and can estimate client-side video buffer occupancy levels associated with the streaming sessions. To estimate a client-side video buffer occupancy level, the network node analyzes packets communicated with the terminal nodes to identify application layer messages and extract transaction information, determine payload types associated with objects conveyed in the packets identified with application layer messages, and associate the objects conveyed in the packets identified with application layer messages with one of the streaming sessions. The network node may use the estimated video buffer occupancy levels to determine scheduler parameters for use in scheduling packets for transmission to the terminal nodes.

Abstract: Systems and methods provide a parameterized scheduling system that incorporates end-user application awareness and can be used with scheduling groups that contain data streams from heterogeneous applications. Individual data queues within a scheduling group can be created based on application class, specific application, individual data streams or some combination thereof. Application information and Application Factors (AF) are used to modify scheduler parameters such as weights and credits to differentiate between data streams assigned to a scheduling group. Dynamic AF settings may adjust relative importance of user applications to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, application characteristics, protocol characteristics, device characteristics, service level agreements, or combinations thereof.

User features include wireless device location and velocity, services-in-use, time of day and day of week. Optionally, circumstantial feature values may be obtained and used to determine the predicted scores.

Abstract: A communication station, such as a base station or access point, has multiple backhaul options and distributes backhaul data between the available backhaul options. The communication station includes a transceiver for transmitting and receiving data with user equipments, multiple backhaul interface modules, and a backhaul distribution module arranged for monitoring demand for backhaul bandwidth and distributing data over the backhauls based on the demand for backhaul bandwidth. Additional modules for user data and control plane processing may be included with the user/control distinction used in distributing data over the backhauls. The backhaul options may include a preferred backhaul and an alternate backhaul. Distributing data over the backhauls may be based, for example, on applications associated with the data, financial cost, delay, robustness, computational resources, and/or additional security associated with using a particular backhaul.

Abstract: Access nodes and methods adjust a bit rate of a data stream in a communication network. The access nodes and methods have a packet inspection unit configured to inspect one or more of the data packets to determine that the data stream includes video data. A congestion unit is coupled to the packet inspection unit and is configured to determine a level of congestion in the communication network, the level of congestion associated with a capacity of the wireless channel, the level of congestion capable of varying over time, and the capacity of the wireless channel capable of varying with the level of congestion. A video scaling unit is configured to adjust the bit rate of the data stream responsive to the packet inspection unit and the congestion unit.
