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: A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

Abstract: A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.

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: A user equipment and a method performed by the user equipment that has a transceiver configured to enable the user equipment to establish a connection with a first network and a second network. The method including establishing a connection to each of the first network and the second network, tuning away from the first network to the second network, tuning back to the first network from the second network and determining whether to perform a network operation with the first network after tuning back to the first 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.
