    Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems operating in unlicensed or shared radio frequency spectrum band may use different modes to manage hybrid automatic repeat request (HARQ) feedback. HARQ feedback may be transmitted autonomously or, in some cases, HARQ feedback may be solicited from a user equipment (UE) for one or several HARQ processes. Solicited feedback may be referred to as polled feedback and autonomous feedback may be referred to as unpolled feedback. Polled and unpolled feedback may be transmitted using different physical channels, and may be grant-based or triggered without an express grant. Buffers for polled and unpolled feedback may be separately maintained and managed. In a multicarrier configuration, uplink control information (UCI) for one or more carriers may be transmitted on a subset of configured uplink carriers. A number of carriers used for UCI may depend on operating conditions of a UE.

    Abstract: Methods, systems, and devices for wireless communication are described. A downlink control message type used for triggering uplink transmissions may convey additional information, including timing for uplink transmissions. The type or format of the control channel (e.g., physical downlink control channel (PDCCH) type or format) used to trigger an uplink transmission may also indicate a starting time or a time period, or both for the uplink transmission. In some cases, downlink control information (DCI) may indicate the function of a downlink control message that includes the DCI. Additionally, system information identified in a downlink control message may be used to determine a subframe length which, in some examples, may be used to determine whether or how long to monitor a discovery reference signal (DRS) subframe.

    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

    Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

    Abstract: A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UEs having different bandwidths, e.g., between a narrowband UE and a wideband eNB. A UE apparatus transmits uplink transmissions in a plurality of transmission units and hops frequency bands in a first pattern across frames based on a base station hopping pattern. The apparatus may transmit uplink transmissions based on dual hopping patterns, and may hop in a second pattern across transmission units within the base station's channel occupancy within a frame. A base station apparatus may hop frequency bands in a first pattern across frames based on a base station hopping pattern, and may receive uplink transmissions in a narrowband from a UE in a plurality of transmission units within the frequency bands based on the base station hopping pattern.

    Abstract: Methods, systems, and devices for wireless communication are described. Resources for narrowband communication in an unlicensed radio frequency spectrum band may be configured and allocated based on resource availability, regulatory constraints, and device capability or category. A narrowband wireless device, such as a machine type communication device or other relatively low complexity device, may communicate using one or more narrowband carriers, which may occupy between one tone and multiple resource blocks in an unlicensed spectrum band (e.g., any number of resources between one (1) tone and multiple resource blocks (RBs)). Different device types may thus be configured differently as they move between geographic regions. The base station may then communicate with the narrowband mobile device based on the resource allocation and the carrier configuration.
