Abstract: Interference mitigation solutions are disclosed for interference experienced based on asymmetric uplink (UL)/downlink (DL) slot configuration. The aggressor/victim network entities are identified using either measurement or static/semi-static means, such that the victim network entities that may be impacted by interference from aggressor network entity transmissions are identified. Inter Cell Interference Coordination (ICIC) mechanisms are extended to negotiate and address scheduling that intelligently mitigates interference that occurs in the colliding slots.

Abstract: Systems, methods, apparatuses, and media are provided for recovery of information from redundancy version packets in systematic encoding environments when a redundancy version packet containing primarily systematic information may be corrupted. A plurality of redundancy version packets may be received at a user equipment device from a transmission device. Each redundancy version packet of the plurality of redundancy version packets may be based on a same group of information bits. A first redundancy version packet of the plurality of redundancy version packets may contain more bits of the same group of information bits than do the other redundancy version packets of the plurality of redundancy version packets. The same group of information bits may be recovered based on one or more second redundancy version packets of the plurality of redundancy version packets but not based on the first redundancy version packet.

Abstract: Dynamic intra-cluster coordination for TDD UL-DL reconfiguration using distributed TDD UL-DL reconfiguration techniques and/or new physical layer signaling. Cell weighting techniques may be used so that distributed TDD UL-DL reconfiguration of the cell cluster can be weighted towards cells of the cluster with higher load. Cells within a cell cluster may independently determine their preferred TDD UL-DL reconfiguration and one or more cells of the cluster may be eligible cells for determining the TDD UL-DL reconfiguration for the cluster. Special subframes may be used for transmission of TDD UL-DL reconfiguration messages from the configuring cell and transmission of ACK messages from other cells of the cluster. The TDD UL-DL reconfiguration message may be an orthogonal sequence based on a signature determined by the cell ID of the configuring cell.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus groups subframes of a time division duplex (TDD) configuration of a serving cell into a set of anchor subframes and a set of non-anchor subframes. The apparatus also separately bundles positive acknowledgements (ACKs) and/or negative acknowledgements (NACKs) of the anchor subframes, and ACKs and/or NACKs of the non-anchor subframes.
