Abstract: The disclosure provides for control plane measurements in a wireless device. The wireless device may perform, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management (RRM) measurements of a cell. The wireless device may identify one or both of a first subset of the RRM measurements associated with a first subset of the sub-frames including opportunistic transmissions and a second subset of the RRM measurements associated with a second subset of the sub-frames including guaranteed transmissions. The wireless device may determine one or more RRM measurement values based on one or both of the first subset of the RRM measurements and the second subset of the RRM measurements. The wireless device may similarly perform radio link management (RLM) measurements and determine RLM measurement values based on the first and second subsets. The wireless device may also use timers for uplink transmissions to detect radio link failures.

Abstract: In the present disclosure, CSI and/or a plurality of ACK/NACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. When the DCI trigger is received, the UE may transmit the CSI and/or GACK. In this way, HARQ feedback and/or CSI may be reliably communicated even if a CCA does not clear and/or UL subframes are unavailable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In an aspect, the apparatus may be a UE. The apparatus monitors one or more subframes for a DCI trigger. In a further aspect, the apparatus receives the DCI trigger in a subframe. In another aspect, the apparatus transmits UCI using a subsequent subframe.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a second base station. The second base station receives a measurement report and a cell identifier, associated with a first base station, from a UE. The second base station determines, based on the cell identifier, that the first base station is in a dormant state. The second base station sends an activation request to the first base station, based on the measurement report, to prompt the first base station to transition from the dormant state to an active state. The second base station further includes handing off the UE to the first base station.

Abstract: Various aspects of the invention provide for determining data rate for a reverse link communication by determining packets of data for transmission for a number of communication services, determining a data rate for transmission of the packets of data based on an arrangement of the packets of data in a queue allowing for meeting the transmission deadline for each of the packets of data. The base station determines whether available resources allow for allocation at the base station for transmission from the mobile station at the determined data rate and duration. The mobile station drops at least a packet of data of the packets of data in the queue to determine a new queue of packets of data. The new queue of the packets of data is used to determine a new data rate for communication on the reverse link.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: Enhanced discontinuous reception (DRX) techniques are discussed for networks configured with some combination of contention-based spectrum. Various aspects provide common or separate DRX configurations across all carriers and cells. Durations may be adjusted to increase the probability of a user equipment (UE) remaining active for the base station to secure the shared channel. Physical layer commands may also be transmitted for UE to enter sleep mode dynamically in order to further save power. Additional triggering signals sent via the physical layer or layer 1 signaling, such as fast wake-up signals or fast sleep signals, may either wake the UE for monitoring the contention-based spectrum of the secondary carrier or cause the UE to enter a sleep mode after monitoring is over. Further aspects provide to initiate DRX procedures in contention-based spectrum in response to detected CUBS or other channel usage signals.

Abstract: Techniques are described for wireless communication. One method includes monitoring, by a first base station of a first operator, for clear channel assessment (CCA) exempt transmission (CET) timing information of a second base station of a second operator; identifying transmission timings of CETs of the second base station of the second operator based at least in part on the monitoring; and discontinuing transmissions of the first base station of the first operator during the transmission timings of the CETs of the second base station of the second operator. Transmissions of the second base station of the second operator may be asynchronous to transmissions of the first base station of the first operator.

Abstract: Techniques are described for wireless communication at a wireless device. One method includes identifying a priority of the wireless device for a transmission interval of a radio frequency spectrum band shared by a plurality of network operating entities; identifying an absence of a predetermined transmission type in each of a number of clear channel assessment (CCA) slots of the transmission interval, in which each of the number of CCA slots is associated with a higher priority than the identified priority of the wireless device; and communicating over the radio frequency spectrum band based at least in part on the identified absence of the predetermined transmission type in each of the number of CCA slots associated with the higher priority than the priority of the wireless device.

Abstract: Certain aspects of the present disclosure relate to techniques for configuring an adaptive frame structure for wireless communications systems using unlicensed radio frequency spectrum. A base station (BS) may determine whether another device is transmitting on a channel in the unlicensed radio frequency spectrum or one or more other network conditions pertaining to the channel, determine a frame structure from a plurality of frame structures used for data communications based at least in part on the one or more network conditions, wherein each of the plurality of frame structures has a different frame duration, and communicate with a user equipment (UE) using the determined frame structure. A UE may determine a frame structure from a plurality of frame structures used for data communications, wherein each of the plurality of frame structures has a different frame duration, and communicate with a BS using the determined frame structure.
