摘要： This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

摘要： A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

摘要： Apparatuses, systems, and methods to perform attachment of a wireless device to a next generation gateway via either a base station of a next generation radio access network (RAN) or a mobility management entity of a legacy RAN. An apparatus may be configured to receive an attachment request from a wireless device, determine authentication information via communication with a home subscriber server, determine, based at least in part on the authentication information, whether the wireless device is capable of communicating via the next generation RAT, and send, in response to determining the wireless device is capable, a connection request to a gateway of the next generation RAN. The authentication information may include subscription information associated with the wireless device.

摘要： This disclosure relates to techniques for performing network initiated downlink data transmissions with a wireless device in a cellular network. According to some embodiments, a wireless device and a cellular network may perform an attach procedure. As part of the attach procedure, the wireless device may indicate to the cellular network to store context information associated with the wireless device after the attach procedure is completed and the wireless device transitions to idle mode. The wireless device may also store context information. The stored context information may be used in conjunction with a network initiated downlink data transaction between the cellular network and the wireless device.

摘要： Described herein are systems and methods for carrier aggregation deployment and organization in unlicensed bands. A method may comprise scanning, by a transceiver within a base station, channels in a band of interest, reporting, by the transceiver, signal measurement information to the base station, cell searching, by the transceiver, channels in the band of interest, determining channel information for neighboring each channel, and transmitting, by the transceiver, the channel information to the base station.

摘要： Methods and apparatus for using an unlicensed radio frequency band component carrier for uplink transmission are disclosed. A wireless communication device receives a carrier aggregation configuration, which can include at least one licensed radio frequency band component carrier and at least one unlicensed radio frequency band component carrier. The wireless communication device establishes a set of radio bearers and associates an unlicensed radio frequency band permission level with each of the radio bearers. The wireless communication device multiplexes uplink traffic for the radio bearers on the at least one licensed radio frequency band component carrier and the at least one unlicensed radio frequency band component carrier based at least in part on the unlicensed radio frequency band permission levels associated with the radio bearers.
