    摘要： Embodiments are provided for header compression with online network codes. A header formulation is used in accordance with the network codes to reduce the header overhead. An agent node between a source of packets and a user equipment (UE) adds to a header in the packets block labels corresponding to blocks of data in the packets. The agent node further adds, to a payload portion of the packets, start and end times for transmitting the blocks. The blocks of data are encoded using an online network coding scheme and the packets are sent to an access node serving the UE. The access node receives the packets, compresses the header by compressing bits of the block labels based on a pre-defined finite number of paths between the agent node and a plurality of access nodes components serving the UE, and sends the compressed header in the packets to the UE.

    摘要： Inter-cell interference can be reduced by re-assigning uplink scheduling responsibilities for a user equipment (UE) from a controller associated with a serving access point (AP) to a controller associated with a neighboring AP, as the controller associated with the neighboring AP may have better access to channel information corresponding to interference experienced by the neighboring AP as a result of uplink transmissions from the UE. After the re-assignment, the controller associated with the neighboring AP may independently schedule an uplink transmission parameter (e.g., a transmit power level, a modulation coding scheme level and/or a precoder) of the UE in a manner that mitigates inter-cell-interference in the neighboring cell.

    摘要： It is possible to improve backhaul resource utilization efficiency during dynamic point selection (DPS) transmissions by unicasting different portions of a traffic flow to different access points participating in the DPS transmission. Specifically, a traffic flow may be encoded to obtain forward error correction (FEC) packets, and different subsets of the FEC packets may be unicast to different access points participating in the DPS transmission. The subsets of FEC packets may have partial (or no) redundancy such that the amount of duplicative data communicated over the backhaul network is reduced when compared to multicasting the entire traffic flow to each access point participating in the DPS transmission. There may be different degrees of redundancy between subsets of FEC packets to achieve different traffic engineering (TE) objectives.

    摘要翻译： 通过将业务流的不同部分单播到参与DPS传输的不同接入点，可以提高动态点选择（DPS）传输期间的回程资源利用效率。 具体地说，业务流可以被编码以获得前向纠错（FEC）分组，并且FEC分组的不同子集可以单播到参与DPS传输的不同接入点。 FEC分组的子集可以具有部分（或否）冗余，使得当将整个业务流组播到参与DPS传输的每个接入点时，通过回程网络传送的重复数据的数量减少。 在FEC分组子集之间可能存在不同程度的冗余，以实现不同的流量工程（TE）目标。

    摘要： 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.
