    Abstract: A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.

    Abstract: The application relates to HetNet mobility improvements and in particular to reduce handover failures. When handing over from a source small cell to a target small cell, it is likely that a UE can end up on a cell that does not have a prepared UE context, because typical small cells are single sector in nature. Then, RRC reestablishment can fail and the UE will be required to perform an attach or service request procedure to recover from the radio frequency (RF) loss. The attach or service request procedure can adversely impact the performance of the UE. The application proposes, in an attempt to improve handover success rate for the UE in a HetNet deployment, the source eNB prepares the overlay macro eNodeB in addition to a target small cell as handover candidates during handover decision making. The UE is informed about the target small cell and eNodeB using RRC messaging. After receiving handover command or detecting RF loss, the UE can try to connect with the target small cell. If UE is unable to connect (RACH FAILURE) to the target small cell, the UE will connect to the macro eNodeB (PRACH RACH & MACH RACH Response)

    Abstract translation: 该应用涉及HetNet移动性改进,特别是减少切换失败。 当从源小小区移交到目标小小区时,由于典型的小小区本质上是单个扇区,所以UE很可能在没有准备好的UE上下文的小区上结束。 然后,RRC重建可能失败,并且UE将被要求执行附着或服务请求过程以从射频(RF)丢失中恢复。 附加或服务请求过程可能不利地影响UE的性能。 该应用提出,为了在HetNet部署中提高UE的切换成功率,源eNB在切换决策期间除了目标小小区之外还准备覆盖宏eNodeB,作为切换候选。 UE使用RRC消息通知目标小小区和eNodeB。 在接收到切换命令或检测RF丢失之后,UE可以尝试连接目标小小区。 如果UE不能连接(RACH FAILURE)到目标小小区,则UE将连接到宏eNodeB(PRACH RACH&MACH RACH Response)

    Abstract: A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This "partial packet decoding" relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

    Abstract translation: 用户设备从基站接收分组。 基于给定分组的不完整内容,用户设备可以在分组仍在接收时调用解码。 这种“部分分组解码”依赖于以冗余(码率小于1)对分组中的底层信息进行编码的事实。 如果链路质量差,则部分分组解码可能不成功,即在尝试恢复基础信息时失败。 为了避免浪费电力,用户设备可以被配置为在对当前分组调用部分分组解码之前应用一个或多个链路质量测试。

    Abstract: Manipulating modulation and coding scheme (MCS) allocation after a communication interruption. A UE device may resume communications with a BS after a communication interruption. First channel quality information may be generated and transmitted to the BS. A first MCS allocation, which may be based at least in part on the first channel quality information, may be received from the BS. Second channel quality information may be generated and transmitted to the BS, where the second channel quality information is modified by an offset configured to modify a second MCS allocation.

    Abstract: For paging user devices that are link budget limited (LBL), a base station transmits a special ID that is used by said devices to identify a paging frame and/or a paging occasion. When transmitting a paging message for an LBL device, the base station may use: (a) larger aggregation and larger CFI (than conventionally allowed) and (b) a larger number of resource blocks (than conventionally allowed) for paging payload. If paging messages for LBL devices saturate the paging frame capacity, the base station may allocate a plurality of special IDs. If paging messages for LBL devices and/or other data transfers saturate network capacity, at least a subset of the LBL devices may be directed to enter a connected-state discontinuous reception (DRX) mode, wherein those devices will remain in connected mode and periodically check for resource allocations. Paging payload information may be repeatedly transmitted in successive subframes, to support soft combining.

    Abstract: Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected "tune-away" period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

    Abstract: Apparatus and methods are disclosed for performing delayed hybrid automatic repeat request (HARQ) communications in the downlink (DL) to reduce power consumption for a user equipment (UE) during a connected mode discontinuous reception (C-DRX) cycle. An enhanced NodeB can be configured to monitor a physical uplink control channel (PUCCH) for DL HARQ information to determine when the PUCCH contains a negative acknowledgement (NACK) message, and in response to determining that the PUCCH contains a NACK message, the eNodeB can wait until a next C-DRX ON duration to transmit a HARQ DL retransmission. The eNodeB can also determine whether or not to bundle the HARQ DL retransmission in consecutive transmission time intervals, based on a signal to interference plus noise ratio (SINR) associated with the UE.
