Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.

Abstract: This disclosure relates to providing coexistence features for cellular communication in unlicensed spectrum. A wireless device may communicate with a cellular base station in accordance with an original communication configuration. The wireless device may determine that a communication activity is occurring at the wireless device that has a duration longer than a duration threshold. The wireless device may provide an indication to the cellular base station to modify the communication configuration with respect to operation in an unlicensed frequency band based at least in part on determining that a communication activity is occurring at the wireless device that has a duration longer than the duration threshold. The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

Abstract: A device, system, and method uses a camp only mode based on a connectivity status. The method is performed at a device that is configured to establish a first connection to a first network and configured to establish a second connection to a second network. The method includes determining the connectivity status of the device. When the connectivity status indicates that the device has established the first connection, the method includes utilizing a camp-only mode to monitor the second network, the camp-only mode reducing a frequency of at least one type of operation associated with the second network, the camp-only mode configured to retain a capability of determining whether an emergency message is being broadcast over the second network.

Abstract: This disclosure relates to broadcast information block assistance for a wireless device. The wireless device may obtain a first plurality of broadcast information blocks from a first base station. The wireless device may receive a second plurality of broadcast information blocks associated with the first base station from a source other than the first base station. The wireless device may determine if the second plurality of broadcast information blocks match the first plurality of broadcast information blocks based on version information specified in the first plurality of broadcast information blocks. When the broadcast information blocks match, the wireless device may use the first and second pluralities of broadcast information blocks to perform communication with the first base station without obtaining the second plurality of information blocks from the first base station.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.

Abstract translation: 描述用于执行数据服务请求延迟的用户设备（UE）设备的设备，系统和方法。 UE可以在小区重选期间检测数据服务请求失败，并且基于小区重新选择的状态推迟数据业务请求的重发。 该状态可以表示UE尝试驻留在小区上，或者UE正在监视与小区重选相关联的一个或多个度量。 为了推迟数据服务请求，UE可以延迟数据服务请求一段指定的时间，或者直到小区重选完成。 可以在协议栈的第一层上监视状态，并且数据服务请求可以由协议栈的第二层生成。 推迟可能是固定的或可变的时间段。

Abstract: Methods and apparatus for the automated altering of wireless device states in response to detected connection behaviors. In one embodiment, a mobile device receives network parameters, some of which are incorrectly configured, from a base station (or access point). To ensure the proper behavior of the mobile device, the device reviews the network provided parameters to determine if one or more of the parameters has been set incorrectly. If so, the device locally alters its own settings to mitigate the incorrect operation associated with the incorrect network provided parameters. In second exemplary embodiment, a number of tolerances are utilized to ensure the proper operation of the mobile device while maintaining an active link. Upon violation of one or more of these tolerances, the device breaks the active link to the wireless network.

Abstract: Techniques discussed herein can facilitate inactive state transmissions for a User Equipment (UE) via a 4-step or 2-step inactive state RACH process. One example aspect is a UE device, comprising: communication circuitry; and a processor configured to perform operations comprising: in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission: transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission; transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.
