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: A user equipment (UE) is configured with a carrier aggregation (CA) functionality and UE connected to a network via a base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) to the UE. The UE determines a plurality of bands that are supported by the UE for use in the CA functionality, generates an individual band information element (IE) including band information for the bands, determines at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination forming a basis to extrapolate a plurality of CA combinations having the order based on the band information, generates a representative CA combination IE including the at least one representative CA combination and transmits the individual band IE and the representative CA combination IE to the base station.

Abstract: This disclosure relates to wireless connection management for an accessory device. A companion device and the accessory device may establish a wireless link. The companion device may associate with a Wi-Fi access point. The companion device may determine whether the Wi-Fi access point supports access by the accessory device to a wide area network. The companion device may determine whether to provide association information for the Wi-Fi access point to the accessory device based at least in part on whether the Wi-Fi access point supports access by the accessory device to the wide area network. The companion device may monitor whether the Wi-Fi access point continues to support access by the accessory device to the wide area network, and may indicate to the accessory device to disassociate with the Wi-Fi access point if the Wi-Fi access point no longer supports access by the accessory device to the wide area network.

Abstract: Method, device, and system being performed by a first station. The method includes receiving a first call identification of a first communication session between the first station and a second station. The method further includes receiving a request, from a third station, to allow the first communication session to be transferred from the first station to the third station. Following the receipt of the request, the method includes displaying a prompt on the first station for permission to allow the first communication session to be transferred to the third station and, when the permission is received, transmitting a response, to the third station, granting permission to transfer the first communication session from the first station to the third station. Additionally, upon the call being transferred, an advisory, such as an audio or visual message, may alert the second client station of the call transfer event.

Abstract: A method is disclosed where a user equipment (“UE”) is operating in a carrier aggregation mode and connected to a first cell operating on a licensed band and a second cell operating on an unlicensed band. The method may include the UE performing a carrier sensing operation on the unlicensed band, determining, from the carrier sensing operation, a duration that the unlicensed band will be occupied, refraining from transmitting data to the second cell on the unlicensed band for the duration that the unlicensed band will be occupied and setting a transmitter in communication with the second cell to a low power mode for the duration that the unlicensed band will be occupied.

Abstract: Described herein are systems and methods for prioritizing frequency selection of a user equipment (“UE”) having a transceiver configured to enable the UE to establish a connection with a network using at least two communication protocols. A method may comprise recording, at the UE, a camped frequency and a camped band with which the UE is communicating with the first network in the first protocol, disconnecting from the first network and connecting to the second network, and disconnecting from the second network and reconnecting to the first network, wherein the reconnecting to the first network includes determining whether one of the camped frequency or a different frequency within the camped band is available for reconnection to the first network, and reconnecting to the first network using the one of the camped frequency or the different frequency within the camped band.
