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, apparatuses, and devices are described for wireless communications. In one method, an opportunity may be identified for a first operator to perform a clear channel assessment (CCA) for a shared spectrum. The opportunity may be based on a priority of the first operator with respect to at least one other operator associated with the shared spectrum. The CCA may be performed for the shared spectrum during the identified opportunity to determine whether the shared spectrum is available for a transmission during a transmission interval.

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 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 devices for wireless communication are described. A wireless system utilizing one or more time-division duplexing (TDD) configured carriers may utilize a dual transmission time interval (TTI) structure (e.g., at the subframe level and symbol-level). The symbol level TTIs may be referred to as low latency (LL) TTIs, and may be organized within LL subframes. A LL subframe may be a subframe that is scheduled for transmissions in one direction (e.g., uplink or downlink, according to a TDD configuration) and may include multiple LL symbols scheduled for both uplink (UL) and downlink (DL) transmissions. Guard periods may be scheduled between adjacent LL symbols that have opposite directions of transmission to enable user equipment (UEs) to transition from receiving mode to transmit mode (or vice versa). The LL subframes may be transparent to receiving devices that do not support LL operations.

Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.
