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： Systems and methods can use client-side video buffer occupancy for enhanced quality of experience in a communication network. The systems and methods provided herein can drive changes in the communication system using control responses. Example control responses include responses for scheduling of packets under capacity constrained conditions. An access node, such as a base station, may transmit video from a server to a client in a user device. The access node can estimate client-side video buffer occupancy and predict video playback stalls. The client-side video buffer occupancy can be estimated by emulating behavior of the client. The buffer occupancy can be used to enhance quality of experience for the user. For example, when the buffer occupancy is low, the access node may increase scheduling priority of packets conveying the video.
