Title: UPLINK INTERFERENCE RESOLUTION
Abstract:
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.
