Abstract: DRS subframes can be configured, generated, or processed with IoT devices that operate in unlicensed and unanchored bands for co-existence according to various aspects. Downlink (DL) communications can be generated that comprise a discovery reference signal (DRS) that configures an Internet of Things (IoT) device to determine a measurement in an unlicensed carrier and enable a cell detection and synchronization for unlicensed narrowband (U-NB) IoT communications. The DL communication can be transmitted via a radio frequency front-end module, or received / processed at the IoT device. DRS symbols of the DRS can be repeated within a subframe of the DL communication to configure at least two Primary Synchronization Signal (PSS) symbols and at least two Secondary Synchronization Signal (SSS) symbols within the subframe of the DL communication, for example.

A network device (e.g., an evolved NodeB, user equipment, or other network device) can enable sPUCCH and ePUCCH carrying HARQ-ACK feedback. Resource allocations for sPUCCH and ePUCCH can be configured by one or more of: a higher layer signaling, an acknowledgement resource indicator (ARI), a control channel element (CCE) index, or a combination thereof.

Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable scheduling UL transmissions on transmission opportunities outside of the UL grants or for multi-carrier UL scheduling. A communication component of the device can operate to process or generate communications on an unlicensed band or a licensed band in response to UL grants and indications provided via a DL transmission for scheduling. An eNB can provide indications to a UE for processing that indicate whether a transmission opportunity is on the same transmission opportunity as the UL grants or an external / outside transmission opportunity. The indications can further trigger an listen-before-talk (LBT) protocol, which can vary between a category 4 LBT or a single LBT interval that is shorter than the category 4 LBT, depending on the indication.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for hybrid automatic repeat request bundling and timing in communication systems. In one example embodiment, a UE receives a first plurality of subframes, each subframe having an associated hybrid automatic repeat request acknowledgement (HARQ-ACK) process. The UE analyses each subframe of the plurality of subframes to generate a HARQ-ACK message associated with each subframe, and aggregates the HARQ-ACK messages associated with each subframe as a first plurality of HARQ-ACK messages in a first uplink subframe. The first uplink subframe is then transmitted to the eNB. In various other embodiments, subframes received at the UE that have not satisfied a processing delay threshold are delayed until a next available uplink subframe after the first uplink subframe.

Abstract: Technology for a user equipment (UE) operable to perform channel state information (CSI) measurements in a License Assisted Access (LAA) system is disclosed. The UE can process information received from a base station in the LAA system. The information can be received within a downlink (DL) transmission burst from the base station. The information can indicate one of: a cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS) transmission power offset value for the DL transmission burst, one or more subframes in the DL transmission burst for which the UE is to perform CSI measurements, or a subframe boundary of the DL transmission burst. The UE can perform a CSI measurement for the DL transmission burst based on the information received from the base station. Subframes of the DL transmission burst can be associated with a substantially similar transmission power.

Abstract: Licensed assisted access (LAA) uplink (UL) transmissions can be performed using UL scheduling, enhanced node B (eNB) listen before talk (LBT), and user equipment (UE) LBT. A scheduling of a UE for UL transmission can include different procedures for a UE to perform LBT before UL transmission. These procedures can be classified as: i) a scheduled UE performing no LBT for UL transmission, ii) a scheduled UE performing fast LBT (as compared to the eNB) with a more aggressive choice of parameters than the eNB and iii) a scheduled UE performing LBT using parameters as used by the eNB for LBT. In some embodiments, the UL grant transmission by the eNB occurs in the unlicensed band after a successful LBT procedure at the eNB.
