Abstract: Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

Abstract: Techniques are provided for transmission of measurement reports from a UE to a base station. A method may include receiving a measurement configuration message from a serving cell. The method may include determining a report value from the measurement configuration message, the report value indicating a number of measurement reports to be transmitted to the serving cell. The method may include, based on the number of measurement reports indicated by the report value, determining whether to wait for a signal measurement result of at least one neighboring cell to become available prior to sending a measurement report to the serving cell.

Abstract: Techniques are provided for adaptively changing a periodicity of measuring signal characteristics for a UE in a relatively high speed environment based on one or more signal characteristics being outside of a threshold. Periodicity of measuring signal characteristics may be made directly by changing an interval at which measurements are taken. In certain examples, periodicity of measuring signal characteristics may be made indirectly by changing the length of a discontinuous reception (DRX) cycle. Some techniques provide one or more radio link monitoring (RLM) parameters may be modified based on a determination that a UE is in a high speed environment or measured signal characteristics are outside of a threshold.

Abstract: A delta configuration is transmitted to a UE requesting a handover wherein the delta configuration details changes that are required for the current UE configuration in order to execute the handover. The handover is initiated via a measurement report transmitted to a currently serving source eNode B from the UE. The measurement report can comprise one or more of current radio conditions, current UE configuration or a preferred target eNode B if the handover is a inter eNode B handover. In a inter eNB handover, the current UE configuration is forwarded to the preferred target eNode B by the source eNode B. The target eNode B generates the delta configuration and transmits it to the source eNode B in a transparent container which is subsequently forwarded to the UE.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.

Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.

Abstract translation: 用户设备（UE）可以在用于上行链路（UL）传输的缓冲器中具有数据。 UE可以发送指示数据量的缓冲器状态报告（BSR）。 BSR可能会失败，或者基站可能无法为数据传输提供足够的资源。 BSR故障条件可以基于数据的无线电链路控制（RLC）操作模式。 例如，数据可以是用于确认模式（AM）DL传输的确认（ACK）。 在这种情况下，UE可以发起BSR重传（Retx-BSR）定时器并且确定是否已经接收到任何重复的传输。 数据也可以与未确认模式（UM）相关联，并且BSR故障条件可以包括等待小于Retx-BSR时间间隔的时间间隔。 当满足BSR故障条件时，UE可以向基站发送调度请求。

Abstract: Methods and apparatuses for re-synchronizing Cell Radio Network Temporary Identifiers (C-RNTIs) in a wireless communication system are disclosed. In an aspect, a random access preamble is sent for random access by a user equipment (UE) and a random access response (RAR) is received that includes a temporary C-RNTI. If the UE already has a valid C-RNTI, a message is sent that includes the valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for the UE. In another aspect, a random access preamble for random access is received and a RAR is sent that includes a temporary C-RNTI. A message is received that includes a valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for a UE if the UE already has the valid C-RNTI.

Abstract: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

Abstract: Methods, systems, devices, and apparatuses are described for wireless communications in which a wireless device may identify a small cell (e.g., SCell) and establish an independent connection with the small cell based at least in part on selection parameters received from a macro cell (e.g., PCell). The selection parameters may include power and/or quality parameters, as wells as a set of candidate cells from which to make the selection. The macro and small cells may be in communication with each other but need not be associated with the same base station (i.e., are not collocated). Once the small cell connection is established, the device may communicate with both cells concurrently. Available uplink data and/or downlink data may trigger the need for the device to connect with the small cell. For example, the small cell connection may be used to communicate uplink/downlink data associated with certain quality-of-service (QoS) and/or bearer identifier.
