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: Cell re-selection in a device configured to operate according to multiple cellular communication protocols. The device may operate according to a first cellular communication protocol at a first time, which may include attaching to a first cell. The device may operate according to a second cellular communication protocol at a second time. Operations according to the first cellular communication protocol may be suspended while operating according to the second cellular communication protocol. The device may attempt to resume operating according to the first cellular communication protocol at a third time. This may include measuring one or more of signal strength or signal quality of the first cell. The wireless device may select a cell to which to attach at the third time based at least in part on the measured signal strength and signal quality of the first cell.

Abstract: Methods to control reconfiguration of multiple radio access bearers in a mobile wireless device connected to a wireless network are described. The mobile wireless device is connected to the wireless network through a voice connection and a data connection simultaneously. The data connection is concurrently active with the voice connection. Transmission of one or more signaling messages for the data connection is delayed until the voice connection terminates. Representative signaling messages include messages that reconfigure a radio access bearer supporting the data connection and messages estimated to exceed a pre-determined transmission time interval.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

Abstract: A UE in an RRC inactive state may determine an operational state mismatch between an actual RRC operational state for the UE and a stored RRC operational state for the UE maintained at a network node. To determine the mismatch, while the UE is in the RRC inactive state, the UE may monitor at least one of paging messages, serving cell power levels, or neighbor cell power levels. When an operational state mismatch is detected, the UE may initiate a state correction procedure rather than an RRC resume procedure.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.
