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. 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.

Abstract: Techniques for performing listen before talk (LBT) channel contention procedures in a shared radio frequency spectrum band are provided. The LBT techniques may include a shortened LBT procedure that may be selected if a base station has reserved a shared channel for a duration of expected user equipment (UE) uplink transmissions, and a full LBT procedure that may be selected if the base station has not reserved the channel for the duration of expected UE uplink transmissions. The shortened LBT procedure may include detecting energy levels of the channel for a relatively short time period relative to the full LBT procedure. The shortened LBT procedure may be selected if a time period between a UE receiving a grant of uplink resources and the beginning of the uplink resources is less than a threshold time value.

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.
