  • Publication number: 20170366308
    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for uplink grants and hybrid automatic repeat requests (HARQ) in communications systems. Some embodiments operate to determine that an unlicensed first channel is idle based on a sensing of the first channel for a first period of time. Such an embodiment may then generate a reservation signal on the first channel and an uplink grant for a first user equipment (UE). After the uplink grant is communicated, the embodiment senses the first channel to detect a physical uplink shared channel (PUSCH) transmission associated with the uplink grant. A HARQ acknowledgment or negative acknowledgement may be sent in various embodiments following the sensing.

  • Patent number: 9800383
    Abstract: Power offset signaling techniques for network-assisted interference cancellation and suppression (NAICS) receivers are described. In one embodiment, for example, user equipment (UE) may comprise at least one radio frequency (RF) transceiver, at least one RF antenna, and logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) connection control message comprising a RadioResourceConfigDedicated field and perform a radio resource configuration procedure in response to receipt of the RRC connection control message, the RRC connection control message to comprise network-assisted interference cancellation and suppression (NAICS) assistance information that identifies a power offset value for one or more transmissions to the UE over a physical downlink shared channel (PDSCH) of a serving cell of the UE. Other embodiments are described and claimed.

  • Patent number: 9763210
    Abstract: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

  • Patent number: 9603140
    Abstract: Device, system and methods for flexible resource allocation are described. In particular, there is described a user receive a user equipment configured to receive higher-layer configuration of flexible resource allocation; receive dynamic information on the downlink resource allocation in a given downlink (DL) subframe; split the resource allocation into resource allocation sub-blocks; independently decode physical downlink shared channel (PDSCH) within each resource allocation sub-block; AND report ACK/NACK for the resource allocation.

  • Patent number: 9590713
    Abstract: In providing feedback to an eNB in an LTE network for downlink scheduling and link adaptation, a UE issues a channel state information (CSI) report that includes a channel quality index (CQI). The reported CQI should include all UE receiver processing capabilities, including NAICS (network assisted interference cancellation and suppression) capability to cancel and suppress interference. Described are measures that may be taken to provide more accurate reporting of CSI by a terminal with NAICS capability.

  • Patent number: 9577778
    Abstract: Technology for reducing signal interference is disclosed. Semi-static signaling can be received at a user equipment (UE) from a neighboring evolved node (eNB). The semi-static signaling can include potential configurations of signal parameters used at the neighboring eNB. The UE can receive dynamic signaling from the neighboring eNB that includes a subset of the potential configurations of signal parameters used at the neighboring eNB. Signal interference that is caused by the neighboring eNB can be reduced using the semi-static signaling and the dynamic signaling.

  • Publication number: 20160302174
    Abstract: Methods, systems, and storage media for monitoring enhanced physical downlink control channel (EPDCCH)-physical resource block (PRB) sets are described. In embodiments, an apparatus may determine a control channel configuration that indicates one or more EPDCCH-PRB sets to be monitored in a desired subframe. The apparatus may determine a control channel configuration that indicates an EPDCCH to be monitored for one or more EPDCCH transmissions in a non-UE-specific search space (SS) in one or more subframes. The apparatus may determine a control channel configuration that indicates a non-UE-specific search space (SS) to monitor for EPDCCH transmissions using one or more aggregation levels. The apparatus may monitor the EPDCCH according to one or more of the control channel configurations. Other embodiments may be described and/or claimed.
