Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured for carrier aggregation (CA) configuration with a primary cell (PCell) and a physical uplink control channel (PUCCH) enabled secondary cell (SCell). The UE may receive a message to activate a deactivated PUCCH-enabled SCell and may perform a PUCCH power initialization procedure, which may include adjusting or determining a transmission power for an initial PUCCH transmission on the activated SCell. The UE may then transmit an initial PUCCH message on the SCell based on the PUCCH power initialization procedure. The PUCCH power initialization procedure may, in various examples, include applying a power adjustment factor to a PUCCH power control setting, monitoring a control channel format for a power control command, or transmitting a power headroom report (PHR) for the SCell at or before activation of the SCell.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may select a coverage enhancement (CE) level based on a coverage limitation. The UE may then receive system information from a base station indicating an index of CE levels and corresponding physical random access channel (PRACH) configurations, and the UE may transmit a random access preamble using the PRACH configuration for the selected CE level. For example, the UE may transmit the preamble based on a frequency offset that corresponds to the selected CE level. In some cases, the UE and base station may also associate groups of preambles with downlink (DL) CE levels. The UE may select a preamble from a group corresponding to a desired DL CE level for a random access response message. The base station may determine the DL CE level based on the group the preamble was selected from and respond accordingly.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a semi-persistent scheduling (SPS) message indicating transmission of a first packet during a first period of a first hybrid automatic repeat request (HARQ) process, and a configuration for TTI-bundled transmission. The apparatus transmits a first TTI-bundled packet on the first resources during the first period of the first HARQ process. The apparatus identifies second resources for transmitting a second TTI-bundled packet during a second period of the first HARQ process based on the SPS message. The apparatus determines whether to offset transmission of the second TTI-bundled packet to a period of a second HARQ process when at least one of the second resources for transmitting the second TTI-bundled packet overlaps with at least one resource used for retransmitting the first TTI-bundled packet according to the first HARQ process.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate power utilization across component carriers (CCs) with different transmission time interval (TTI) configurations. For example, the UE may reserve a portion of the transmit power for a CC with a reduced TTI length (e.g., an enhanced CC (eCC)). In other examples, the UE may dynamically allocate power between CCs with overlapping uplink periods. That is, the UE may borrow power allocated to one CC to transmit on an eCC. The UE may use a prioritization scheme to determine the transmit power for each CC. In some cases, the UE may send a power headroom report based on the power level of the eCC. The power headroom may be a virtual power headroom based on predicted eCC transmission power, or an actual power headroom based on uplink scheduling.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 用户设备（UE）可以以不同的传输时间间隔（TTI）配置协调跨分量载波（CC）的功率利用。 例如，UE可以为具有减小的TTI长度的CC（例如，增强型CC（eCC））保留用于CC的发射功率的一部分。 在其他示例中，UE可以在具有重叠的上行链路周期的CC之间动态地分配功率。 也就是说，UE可以借用分配给一个CC的功率在eCC上进行发送。 UE可以使用优先化方案来确定每个CC的发射功率。 在某些情况下，UE可以基于eCC的功率电平发送功率余量报告。 功率余量可以是基于预测的eCC发送功率或基于上行链路调度的实际功率余量的虚拟功率余量。

Abstract: Methods, systems, and apparatuses for enabling and utilizing variable length transmission time intervals (TTI) are described. Latency for communications between base stations and user equipment (UEs) may be reduced by flexibly and dynamically adapting to data traffic needs. TTI for a given UE may be dynamically adjusted according to UE or system requirements and the configuration of uplink and downlink TTI. A base station may utilize dynamic grants to schedule resources within a system. A UE may receive a grant in a first portion of a variable TTI. The UE may determine a duration of the variable TTI based on the grant, and the UE may communicate accordingly. The UE may receive a subsequent grant in the variable TTI—either in the first portion or another portion—and may respond or alter its operation accordingly.

Abstract: Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message.

Abstract: Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.

Abstract translation: 时分复用（TDM）分区是在同频道部署中为异构网络（HetNet）ICIC考虑的小区间干扰协调（ICIC）机制之一。 例如，在预分配给演进节点B（eNB）的子帧中，相邻eNB可能不发送，因此可能减少被服务用户设备（UE）经历的干扰。 半静态调度（SPS）授权可能具有各种可用的周期性，这可能与TDM分区不兼容。 因此，UE可能错过针对UE不可用的子帧调度的SPS机会。 因此，在具有TDM分割的异构网络中使用具有小周期性的SPS授权可能需要改变，其可以包括调整SPS授权的周期性，基于资源划分信息（RPI）重新安排上行SPS消息，和/或基于 当前SPS赠款。
