Abstract: Techniques are described for wireless communication. One method includes identifying a priority parameter associated with data to be transmitted on an uplink carrier; selecting, based at least in part on the identified priority parameter, between a first type of message for requesting uplink resources in a shared radio frequency spectrum band or a dedicated radio frequency spectrum band, or a second type of message for requesting uplink resources in the dedicated radio frequency spectrum band; and transmitting the selected type of message.

Abstract: The disclosure provides a method and system for requesting access to resources for uplink communications in unlicensed spectrum. In particular, a user equipment (UE) may detect one or more of a first type of data or a second type of data to be transmitted to a base station (BS). The UE may then determine if a first type of physical random access channel (PRACH) resource is available for transmitting one or more of the first type of data or the second type of data to the BS. If the first type of PRACH resource is available, then the UE may transmit one or more of the first type of data or the second type of data using the first type of PRACH resource. If the first type of PRACH resource is not available, then the UE may transmit the second type of data using a second type of PRACH resource.

Abstract: Techniques are described for managing QoS parameters of a bearer for which at least a portion of bearer data is served over a WLAN radio access technology. According to these techniques, a first device may identify a first set of one or more QoS parameters for serving a bearer over a wireless wide area network (WWAN). The first device may also determine a second set of one or more QoS parameters for serving the bearer over the WLAN based on an association between the first set of QoS parameters and the second set of one or more QoS parameters.

Abstract: Improvements to signaling procedures for use in physical random access channel (PRACH)-based proximity detection are disclosed. Signaling and signaling processes from a serving base station may trigger a more efficient and reliable transmission of PRACH from related user equipment (UE). At the dynamic power nodes (DPNs) monitoring for such PRACH-based proximity, features are disclosed which establish neighbor lists for more efficient management of detection and proximity activation.

Abstract: Mitigation of inter-base station resynchronization loss in wireless networks including contention-based shared frequency spectrum is discussed. Aspects of such mitigation provide for base stations entering into an idle mode when a transmission opportunity occurs in a radio frame of the next resynchronization occasion. Additional aspects provide for the base station to signal a flexible listen before talk (LBT) frame length to the user equipment (UE), either with or without explicit signaling of the downlink-uplink division. Further aspects provide for the base station to signal a reset indication to UEs that will prompt the UEs to monitor for downlink channel reserving signals prior to the current LBT frame ending by the resynchronization occasion.

Abstract: Wireless communications systems and methods related to determining scheduling and transmission timeline for communicating in a shared communication medium are provided. A first wireless communication device communicates, with a second wireless communication device, scheduling information during a first time period of a first transmission opportunity (TXOP) of a first network operating entity in a shared communication medium, the scheduling information indicating an offset time period relative to the first time period. The first wireless communication device communicates, with the second wireless communication device, a communication signal during a second TXOP subsequent to the first TXOP based on the offset time period.
