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.
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.
Abstract:
A method to trigger aperiodic CSI reports in LTE TDD systems having dynamic uplink-downlink configurations is proposed. When uplink grants can be sent on any subframe, the method further defines how to indicate which measured subframe set is to be used in reporting the aperiodic CSI. The method is useful for homogeneous networks and networks employing enhanced interference management and traffic adaptation (eIMTA).

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.
