Abstract
Official abstract text for this publication.
Base stations (BSs) can remove inter-BS interference components from received uplink signals using downlink information communicated over a backhaul network. The downlink information is associated with downlink transmissions of neighboring base stations, and is used to remove the inter-BS interference in accordance with interference cancellation techniques, e.g., signal interference cancellation (SIC), etc. The downlink information includes information associated with downlink transmission of the interfering BSs, such as information bits (e.g., data), parity information, control information, modulation and coding scheme (MCS) parameters, forward error correction (FEC) parameters, and other information. Additionally, inter-BS interference can be suppressed using channel information of interference channels using interference suppression techniques, e.g., interference rejection combining (IRC), etc.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for removing interference from received signals, the method comprising: transmitting, by a base station, a serving downlink transmission to a first mobile device, the base station engaged in full-duplexed communications such that uplink and downlink signals are communicated over the same time-frequency resources; receiving, by the base station, an uplink signal comprising an uplink transmission from a second mobile device and interference attribut…
