  • Patent number: 9917621
    Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

  • Patent number: 9838944
    Abstract: A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.

  • Patent number: 9781736
    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.

  • Patent number: 9730153
    Abstract: Embodiments are provided for a multi-objective scheme for solving a cell switch-off problem. The multi-objective solution seeks to minimize or reduce network energy consumption by switching off some of the cells in the network while allowing enough capacity according to traffic needs and quality of service requirement. An embodiment method includes determining, for each one of a plurality of established traffic profiles, a set of solutions with respect to a number of active cells from a plurality of cells in the network and an aggregate network capacity. The method further includes matching a given traffic profile to one of the established traffic profiles, and evaluating performances of the solutions corresponding to that traffic profile. A solution from the solutions is then selected in accordance with the evaluation. The selected solution indicates which of the cells in the wireless network to be switched off.

  • Patent number: 9723572
    Abstract: Methods and systems for facilitating uplink power control (PC) and scheduling in a wireless network are provided. In one example, common interference patterns are obtained from long term channel statistics, and used to perform local PC and scheduling by distributed base stations (eNBs). In some implementations, the common interference patterns are obtained through statistical narrowing techniques that identify common ones out of a plurality of potential interference patterns. The common interference patterns may specify maximum interference thresholds and/or individual eNB-to-eNB interference thresholds which may govern the local PC and scheduling decisions of the distributed eNBs.
