Abstract: Methods, systems, and devices are described for wireless communication within and for user equipment (UE), including lower-complexity devices, which may have intermittent communication needs, low data rates, hard-to-reach locations, and the like. Devices within a wireless communication system may utilize transmission time interval (TTI) bundling to identify and employ various encoding schemes according to particular channel, transmission, and/or environmental conditions. Devices may also monitor and/or decode control-based transmission, control-less transmission, or both. In some examples, devices may monitor various channels based on a TTI bundling length. Some or any of these techniques may allow for coverage enhancement of UEs, including low-complexity UEs.

Abstract: Systems and methodologies are described that facilitate simultaneous transmission of control information in a single sub-frame. For instance, simultaneous transmission can maintain single carrier waveforms for a control channel even when a plurality of information types is scheduled in concurrently. Channel quality indicators, scheduling requests and acknowledgement messages can be jointly coded. In addition, reference symbols in a sub-frame can be modulated to indicate values associated with a scheduling request or an acknowledgement message. Moreover, in situations where channel quality indicators, scheduling requests and or acknowledgement messages are simultaneously scheduled, one or more can be dropped. Further, a single carrier constraint can be relaxed to enable simultaneous transmission of information in the sub-frame at different frequencies.

Abstract: UE-assisted management of advanced radio link feature in a wireless communication network may include a network entity determining that a mobile entity is capable of communicating with one or more base stations using a set of radio link configurations, receiving a request from the mobile entity to restrict use of at least one of the radio link configurations, and restricting use of the at least one of the radio link configurations for communicating with the mobile entity, based on the request. The request may indicate a reason for the restriction, and the network entity may determine whether to restrict based on the reason. Once a radio link configuration is restricted, it may similarly be unrestricted based on a subsequent UE request, or based on expiration of a time period.

Abstract: Techniques are described for wireless communication. A first method may include transmitting a reference signal from an access point over a shared spectrum to a user equipment (UE), and receiving a measurement of the reference signal from the UE. A second method may include receiving at a UE over a shared spectrum a reference signal from an access point, and transmitting a measurement of the reference signal to the access point. In each of the first and second methods, the measurement may indicate interference with the shared spectrum from outside of a clear channel assessment (CCA) range of the access point. A third method may include receiving a plurality of reference signal measurements, where each reference signal measurement corresponds to one of a plurality of access points and indicates interference with a shared spectrum from outside of a CCA range of the corresponding access point, and performing channel selection for the plurality of access points based at least in part on the received reference signal measurements.

Abstract: A method, a computer program product, and an apparatus for separating a cell cluster to two or more cell clusters are provided. The cell cluster may be separated into two or more cell clusters in order to mitigate interference between cells while allowing for TDD subframe configuration flexibility. The method identifies at least one separating cell in a cell cluster, the cell cluster including at least two cells having a common TDD subframe configuration, where a coupling loss between one cell in the cell cluster and at least another cell in the cell cluster is lower than a predefined threshold. The method separates the cell cluster based on the at least one separating cell into at least a first cell cluster and a second cell cluster and sets a first TDD subframe configuration for the first cell cluster and a second TDD subframe configuration for the second cell cluster.
