Abstract: Techniques are disclosed relating to acknowledgements and preemption indicators in the context of multiplexing different services on wireless physical layer frames. In some embodiments, transport blocks for a transmission are divided into code blocks and code block groups. Information indicating the division may be communicated between a base station and mobile device. In some embodiments, a preemption indicator is transmitted which indicates a portion of the transport block preempted by another data service, and the preemption indicator is specified at a different granularity than a code block group. In some embodiments, acknowledgement information is transmitted that indicates, for each code block group included in the transport block, whether the code block group was successfully decoded by the user device. In various embodiments, the disclosed techniques may facilitate preemption by a low-latency, high-reliability data service.

Abstract: A system and methods that are performed by a macro cell and a user equipment (UE) to implement a carrier aggregation mode in a network. The system includes a macrocell including a first coverage area and a plurality of small cells, each of the small cells including a second coverage area wherein the plurality of second coverage areas substantially cover the first coverage area. The macro cell operates a first component carrier as a primary component carrier in a carrier aggregation enabled network and one of the small cells operates a second component carrier as a secondary component carrier in the carrier aggregation enabled network.

Abstract: Apparatuses, systems, and methods for a wireless device to detect intermodulation issues and configure a transmission scheme to remedy detected intermodulation issues. The wireless device may perform measurements on a downlink carrier while one uplink carrier is scheduled for the wireless device. The wireless device may also perform measurements on the downlink carrier while two uplink carriers are scheduled for the wireless device. The wireless device may provide information based on those measurements to a serving base station. The base station may determine that an intermodulation issue is occurring at the wireless device based on the information provided, and may configure the wireless device to use a single uplink carrier at a time based at least in part on the intermodulation issue.

Abstract: Apparatuses, systems, and methods for transmitting a preamble. The UE may transmit a preamble to a base station in a random access channel (RACH). The RACH may be located in unlicensed spectrum. The bandwidth of the preamble may cover a majority of a nominal channel bandwidth of the RACH. The UE may receive a random access response and establish a connection with the base station in response to receiving the random access response.

Abstract: This disclosure relates to aggregation of radio resources provided according to multiple radio interfaces. According to some embodiments, a base station may establish a radio bearer with a wireless user equipment (UE) device. The radio bearer may initially utilize a first radio interface between the base station and the UE. The base station may receive an indication to aggregate radio resources of an access point that utilizes a second radio interface for the UE. Based on the indication to aggregate radio resources for the UE, the base station may redirect at least a portion of data of the radio bearer by way of the access point to be exchanged with the UE using the second radio interface.

Abstract: Apparatuses, systems, and methods for a wireless device and base station using a first radio access technology to monitor traffic load on a second radio access technology. A wireless device may monitor traffic of the second radio access technology and may transmit one or more traffic load reports to the base station. The base station may, based on the report(s) and its own observations, determine whether a hidden network of the second radio access technology is present at the wireless device.

Abstract: This disclosure relates to techniques for managing and monitoring access to a cellular network using unlicensed spectrum. According to some embodiments, policy information indicating permissible and/or non-permissible uses of unlicensed spectrum to access a radio access network of the cellular network may be distributed to elements of the radio access network, such as base stations. A base station establishing a radio bearer with a wireless device may receive information regarding a service type associated with the radio bearer and may determine radio bearer characteristics, potentially including whether to establish the radio bearer using unlicensed or licensed spectrum, based at least in part on the service type associated with the radio bearer and the network policy information. The base station and/or the user device may also report information regarding unlicensed (and possibly also licensed) network access by the user device to a core network of the cellular network.
