Abstract: Techniques for low power voice communications include determining a time between an arrival of data for uplink transmission by a device and a scheduling request (SR) occasion, the SR occasion occurring after the arrival of the data and within an on duration of a discontinuous reception (DRX) cycle, and delaying transmission of a SR by the device during a time period that begins at the arrival of the data for uplink transmission and continues for the determined time.

Abstract: This disclosure relates to techniques for customizing a data radio bearer re-establishment throttle timer for a wireless device. A data radio bearer (DRB) re-establishment throttle timer length may be determined for a first DRB, based at least in part on characteristics of the DRB, such as a packet delay budget for the DRB. It may be determined that radio link failure has occurred for the DRB. An unsuccessful attempt to re-establish the DRB may be performed. A DRB re-establishment throttle timer may be initiated. The determined DRB re-establishment throttle timer length may be used as the length of the DRB re-establishment throttle timer. A subsequent attempt to re-establish the DRB may be performed after expiration of the DRB re-establishment throttle timer.

Abstract: A mobile device collects received information and processes it. In some instances, the mobile device detects, based on the collected information, that a base station is likely not legitimate, i.e. , it is likely a fake base station, and the mobile device bars communication with the base station for a time. In some embodiments, the mobile device determines, based on the received information, that the base station is a genuine base station. When the mobile device determines that the base station is a genuine base station or the mobile device does not determine that it is likely the base station is a fake base station, the mobile device allows or continues communication with the base station.

Abstract: Systems and methods for reducing collisions of transmission data for a first subscriber (e.g., a voice subscriber) with transmission data for a second subscriber (e.g., a data subscriber) at a dual sim dual active (DSDA) user equipment (UE) are described herein. A DSDA UE may be configured to implement a modified skipUplinkTxDynamic feature that avoids collisions by buffering transmission data of the data subscriber and sending a (later) scheduling request (SR) for a grant for that data. A DSDA UE may regulate data subscriber transmissions to avoid a transmission duration for the voice subscriber. A DSDA UE may reduce certain transmissions for a voice subscriber (subject to a block error rate (BLER) threshold for the voice subscriber) to lower the probability of collision. A DSDA UE may operate a data subscriber and a voice subscriber in the same cell to avoid collisions due to RF tuning and/or relative slot overlap.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Abstract: This disclosure relates to techniques for reducing overhead associated with packet switched voice service registration. According to some embodiments, a cellular network entity associated with a cellular network may receive a request relating to packet switched voice service from a wireless device. It may be determined whether subscription information for the wireless device indicates that packet switched voice service from the cellular network is permitted to the wireless device. A response to the request indicating whether packet switched voice service from the cellular network is available to the wireless device may be provided to the wireless device. The response may be generated based at least in part on the subscription information.

Abstract: Performing a circuit-switched fallback, CSFB, call with improved reliability. A request to establish a CSFB call may be received by a UE (106) that is currently in a pool overlap area. The network resource controller (172), or the base station (102), transmits information to the UE which indicates the pools in which neighboring cells are operating. The UE uses this information to select a circuit-switched cell on which to operate for the CSFB operation, wherein the selected CS cell is in the same pool area as the current pool area. This prevents the UE from inadvertently camping on a CS cell in a different pool area, which could cause call failure on some networks. The information provided by the base station may comprise a pool area id, or may comprise mapping relation information that is useable by the UE to determine the current pool area.

Abstract translation: 执行电路交换后备，CSFB，提高可靠性。 建立CSFB呼叫的请求可以由当前在池重叠区域中的UE（106）接收。 网络资源控制器（172）或基站（102）向UE发送指示相邻小区正在操作的池的信息。 UE使用该信息来选择其上用于CSFB操作的电路交换小区，其中所选择的CS小区与当前池区域在同一池区域中。 这样可以防止UE在不同池区域的CS小区上无意中驻留，这可能导致某些网络的呼叫失败。 由基站提供的信息可以包括池区域id，或者可以包括可用于UE来确定当前池区域的映射关系信息。

Abstract: A method for returning to a first network from a second network after premature termination of a CSFB voice call is provided. The method can include a wireless communication device storing cell information for the first network while connected to the first network; participating in a CSFB procedure to transition to thesecond network in response to initiation of a voice call; and determining that the voice call has prematurely terminated. In response to premature termination of the voice call, the method can further include performing a scan for a first network cell based on stored cell information for up to a maximum scan time period; reselecting to a first network cell in an instance in which a first network cell is identified by the scan; and camping on the second network in an instance in which a first network cell is not identified by the scan.
