Abstract: A user equipment (UE) has a cellular connection established by a cellular chip, the cellular connection including a secondary component carrier (SCC) of carrier aggregation (CA) in the unlicensed spectrum. The UE receives, by a WiFi chip of the UE, a message from the cellular chip indicating a first frequency band corresponding to the SCC, determines whether a hotspot service is enabled utilizing at least a portion of the first frequency band that the cellular chip has indicated corresponds to the SCC and when the hotspot service is enabled, switches, by the WiFi chip, the hotspot service from the first frequency band to a second frequency band.

Abstract: This disclosure relates to providing a reservation signal for cellular communication in unlicensed spectrum. A cellular base station may perform a listen-before-talk procedure on an unlicensed frequency channel. The cellular base station may transmit a reservation signal on the unlicensed frequency channel after successfully performing the listen-before-talk procedure. The cellular base station may perform carrier sensing on the unlicensed frequency channel at least once during the duration of the reservation signal. The cellular base station may perform cellular communication on the unlicensed frequency channel after ceasing transmitting the reservation signal.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

Abstract: A device and method for throttling carrier aggregation (CA) in a device connected to a CA enabled network. The method includes determining that a carrier aggregation state of the device is enabled by a network component of a CA enabled network to which the device is connected, determining at least one condition indicating that the carrier aggregation functionality is unnecessary, generating a throttling indication to indicate to the network that a secondary serving cell (SCell) providing a secondary component carrier (SCC) in the carrier aggregation functionality is to be disabled and transmitting the throttling indication to the network component.

Abstract: This disclosure relates to techniques for enabling a user equipment (UE) to determine which cell to attach to in a heterogeneous network (HetNet). The UE may determine, based on the quality of the downlink (DL) channel and/or on the type of traffic between the UE and a current base station, whether to attach to a small cell base station or an overlay macro base station in the cellular network. Particularly, the UE may determine whether to use a received mobility offset during cell reselection in response to a measured quality of the DL channel.

Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A method for resuming a voice call on a legacy network is provided. The method can include a wireless communication device establishing a voice call with a remote device over a first cellular network; determining that a connection quality of the first cellular network has dropped below a threshold connection quality; sending a notification that the wireless communication device is releasing the voice call to transition to a legacy cellular network and will resume the voice call on the legacy cellular network; releasing the voice call on the first cellular network; transitioning to the legacy cellular network; establishing a second voice call with the remote device on the legacy cellular network; and using the second voice call to resume the voice call with the remote device.
