摘要： 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. Scheduling parameters may be dynamic and incorporate the notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to optimally manage video traffic during periods of congestion.

摘要： Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. 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. The systems and methods prioritize packets and make discard decisions based upon the prioritization. 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.

摘要： An access node in a wireless communication network conducts interference resolution to resolve decoding ambiguities in a received uplink transmission. The access node is assisted by receiving uplink transmission data from another, assisting access node. The received uplink transmission data may include, for example, frequency domain data elements as received by the assisting access node and received and expected reference signals. The access node uses the received uplink transmission data and related local uplink transmission data to estimate channel transfer functions which are then used to estimate and decode the received data. The access node may also improve estimated channel transfer functions by cross-correlation nulling.

摘要： 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.

摘要： 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.
