Abstract: Presented herein are techniques for detecting establishment of a bearer associated with a communication session offloaded from a mobile carrier network to a wireless local area network, such as a Wi-Fi® network, and sending, from the mobile carrier network to the wireless local area network, an indication of a level of quality of service (QoS) to be applied to a segment of the communication session that is conveyed by the wireless local area network. The indication of the level of QoS may be passed via a network controller.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for uplink and downlink communications that defines subframe configuration options for each subframe of a frame. For example, the configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device may determine a constraint for a subframe of the frame based on the configuration and determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may communicate during the subframe according to the adaptive subframe configuration rather than the original configuration. The adaptive subframe may be constrained by the identified uplink and downlink configuration, which may avoid disruption to UEs.

Abstract: A base station (BS) operated in an unlicensed band configures a first energy detection threshold for a discovery signal and a second energy detection threshold for data, and performs energy detection. The BS transmits the discovery signal to a user equipment in the unlicensed band if a detected energy based on the energy detection is less than the first energy detection threshold. Further, the BS transmits the data to the user equipment in the unlicensed band if the detected energy based on the energy detection is less than the second energy detection threshold. The first energy detection threshold for the discovery signal is higher than the second energy detection threshold for the data.

Abstract: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit in base station sets a first resource candidate group, which enables terminal capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

Abstract: Among other things, flow rates of traffic among endpoints in a network are controlled. Notifications are received about flowlets originating or received at the endpoints. Each of the flowlets includes one or more packets that are in a queue associated with a corresponding flowlet. In response to the received notifications, updated flow rates are computed for the flowlets. The updated flow rates are sent to devices for use in controlling flow rates for the flowlets in accordance with the computed updated flow rates.
