A first type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion of a transmission resource, transmitting broadcast traffic on at least one first antenna of a plurality of antennas in the first traffic portion using a first sub-channelization, transmitting multicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, in the first traffic portion using a second sub-channelization, and transmitting unicast traffic on at least one antenna of the plurality of antennas in the second traffic portion using a third sub-channelization.

Abstract: 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.

Abstract: A controller having access to channel information associated with a neighboring access point (AP) may communicate a mask to a served user equipment (UE). The mask may specify transmission parameters for an uplink transmission between the served UE and a serving AP such that a successful decoding probability of the uplink transmission at the neighboring AP exceeds a threshold. The mask may specify a maximum MCS level for the uplink transmission, a minimum transmit power level for the uplink transmission, and/or a precoder constraint for the uplink transmission that produces constructive interference at a spatial location of the neighboring AP. This may enable the neighboring AP to isolate the uplink transmission from uplink wireless signals using an interference cancellation technique, e.g., successive interference cancellation (SIC) techniques.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments are provided for assessing radio resource requirements using virtual bin virtualization. An embodiment method includes receiving a service request from a user equipment (UE) in a geographical bin. Resource requirements are then obtained, from a lookup table (LUT), for a serving radio node and neighbor radio nodes associated with the geographic bin of the UE. The LUT comprises a plurality of entries that map combinations of path losses of wireless links for the serving radio node and neighbor radio nodes to corresponding combinations of resource requirements. The entries of the path losses further include one or more service specific and network node parameters for the serving radio nodes and neighbor radio nodes, which are also mapped to the resource requirements. The obtained resource requirements are then assessed, including deciding whether to serve the UE according to the resource requirements and to resource availability.

Abstract: Embodiments are provided for traffic scheduling based on user equipment (UE) in wireless networks. A location prediction-based network scheduler (NS) interfaces with a traffic engineering (TE) function to enable location-prediction-based routing for UE traffic. The NS obtains location prediction information for a UE for a next time window comprising a plurality of next time slots, and obtains available network resource prediction for the next time slots. The NS then determines, for each of the next time slots, a weight value as a priority parameter for forwarding data to the UE, in accordance with the location prediction information and the available network resource prediction. The result for the first time slot is then forwarded from the NS to the TE function, which optimizes, for the first time slot, the weight value with a route and data for forwarding the data to the UE.

Abstract: Forward Error Correction (FEC) techniques that generate independently decodable resource blocks are beneficial for Successive Interference Cancellation (SIC) demodulation. One FEC technique for generating independently decodable resource blocks includes mapping locally decodable FEC codeblocks into unique resource blocks such that substantially all of the bits of the FEC codeblock are carried within a single resource block. The locally decodable FEC codeblocks can be generated from different FEC encoding modules or from a common FEC encoding module. Another technique for generating independently decodable resource blocks includes encoding a stream of information bits into low-density parity-check (LDPC) codeblocks having high ratios of inward peering parity bits. These high ratios of inward peering parity bits allow substantial portions of each LDPC codeblock to be decoded independently from information carried by other LDPC codeblocks.

The out-of-cluster utility component is computed in accordance with the coarse scheduling information.
