Abstract: Systems and methods adapted to provide transmission of communication acknowledgments to facilitate effective delivery and processing of acknowledgments are disclosed. Embodiments may utilize one or more special definition of header and/or control bits (e.g., length indicator, extension field, etc.), special grants (e.g., a grant to carry control PDUs and/or data PDUs with one or more ACKs), and/or one or more special logical channel/radio bearer (e.g., a logical channel having higher priority than regular data bearer traffic) for delivery of acknowledgments, to expedite processing of the acknowledgments, etc. A device receiving such acknowledgments may identify a packet as including one or more acknowledgment upon decoding/deciphering the received packet, such as by detecting a header field containing special data or by receiving the acknowledgment via a special bearer channel, whereby the acknowledgments may be extracted and delivered to upper layers without waiting for all the in-sequence packets to be received or processed.

Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station. In some aspects, the mobile device may scramble the information associated with signals and transmit the information associated with signals to the base station prior to establishing a security context for a connection between the mobile device and the base station.

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may determine whether to configure the UE for a first type of resource sharing or a second type of resource sharing between a first radio access technology (RAT) and a second RAT, wherein one or more UE resources are configured for use with the first RAT. The UE may reconfigure the one or more UE resources for use with the second RAT based at least in part on determining whether to configure the UE for the first type of resource sharing or the second type of resource sharing.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for adjusting flow rate of transmissions received at a device. A user equipment (UE) determines, in response to detecting a trigger condition, a proposal to adjust feedback provided to a base station (BS) in order to adjust a flow rate of transmissions received at the UE from the BS. The UE adjusts the feedback based on the proposal and at least one additional condition and transmits the adjusted feedback to the BS.

Abstract: Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.

Abstract: Techniques are provided for efficient handover of a user equipment (UE) between base stations that operate using different radio access technologies (RATs). A handover message to a UE may indicate that the UE is to be handed over from a source base station operating according to a first RAT to a target base station operating according to a second RAT. The handover message may be configured to be transmitted using the first RAT and include embedded information, that is transparent to the first RAT, for the handover to the target base station using the second RAT.

Abstract: Aspects of the present disclosure generally relate to wireless communication and to mechanisms designed to help improve dynamic sharing of one or more receive chains among different radio access technologies (RATs). For example, the mechanisms may be used with LTE and other RATs where Carrier Aggregation is used for simultaneous voice and LTE (SV-LTE) applications.
