Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.

Abstract: A station that performs a method to coordinate transmissions of scheduling requests (SR) with OnDurations of a connected discontinuous reception (C-DRX) cycle. The station receives a packet at a packet arrival time relative to a schedule indicating the SR opportunities and onDurations, the SR opportunities occurring at a first interval, the onDurations occurring at a second interval, the first interval being less than the second interval. The station determines an SR opportunity subsequent to the packet arrival time that precedes an entirety of a subsequent onDuration, such that a transmission duration to transmit the SR and the packet maximally overlaps with the selected onDuration. A sleep mode of the processor of the station is used until a time associated with the selected SR opportunity. An active mode of the processor is used to transmit the SR and receive control channel information during the onDuration.

Abstract: A method for adaptively disabling receiver diversity is provided. The method can include a wireless communication device determining an active data traffic pattern; defining a threshold channel quality metric based at least in part on a threshold channel quality needed to support a threshold quality of service for the active data traffic pattern; comparing a measured channel quality to the threshold channel quality metric; and disabling receiver diversity in an instance in which the measured channel quality metric satisfies the threshold channel quality metric.

Abstract: Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1X operation), a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the LTE and CDMA 1X networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1X paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1X pages, overall LTE network performance is minimally affected.

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.
