Abstract: Certain aspects of the present disclosure relate to methods and apparatus for managing control and data transmissions for low cost UEs. In certain aspects, multiplexing of a control channel and data channel may be allowed in a Physical Resource Block (PRB) pair of a subframe. An indication may be provided to the UE regarding whether a portion of resources of the PRB pair not used to transmit the control channel is available for transmitting the data channel. In alternative aspects, control and data may be scheduled in different subframes, such that there is no need to multiplex them in a subframe or a PRB pair in a same subframe.

Abstract: Methods, systems, and devices for wireless communication are described. User equipment (UE) and base stations may support frequency hopping with fast retuning for enhanced machine type communication (eMTC). For example, a UE may need to retune portions of its receive or transmit chain to support operation on various frequency bands, and it may perform the retune within a few symbols. Both base station and UE may anticipate or account for the retuning delay and communicate accordingly. A base station may refrain from transmitting for a certain period of time, for example. A base station may also account for frequency hopping delays for uplink communications. Systems may employ other techniques to support eMTC. For example, UEs may leverage reference signal patterns in certain control channels for demodulation. In some cases, base stations may alter control channel transmissions to account for various types of UEs with in the system.

Abstract: A wireless device may determine a coverage enhancement (CE) level (or coverage extension) by attempting to decode a received broadcast signal. The wireless device may attempt to decode a portion of the broadcast signal using a CE level that is less than the CE level of the broadcast. If the decoding attempt is successfully, the CE level may be declared as an operating CE level. If decoding is unsuccessful, the CE level may be increased decoding retried. The wireless device may continue to test-decode the broadcast signal at new (e.g., increasing) CE levels until a CE level is sufficient for a decode and is declared the operating CE level of the wireless device. In some cases, the wireless device test-decodes a broadcast channel after selecting a CE level based on a path loss measurement of a downlink signal (e.g., reference signal).

Abstract translation: 无线设备可以通过尝试对所接收的广播信号进行解码来确定覆盖增强（CE）级别（或覆盖扩展）。 无线设备可以尝试使用小于广播的CE级别的CE级别来解码广播信号的一部分。 如果解码尝试成功，则CE级别可以被声明为操作的CE级别。 如果解码不成功，则CE级别可能会增加解码重试。 无线设备可以继续以新的（例如，增加）CE级别对广播信号进行测试解码，直到CE级别足以用于解码，并且被宣告为无线设备的操作CE级别。 在某些情况下，无线设备在基于下行链路信号的路径损耗测量（例如，参考信号）选择CE级别之后对广播信道进行测试解码。

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.

Abstract: Heterogeneous networks incorporate various small cells, such as femto cells and pico cells, in addition to a macro cell. Existing signals (e.g., PSS and SSS) configured as discovery reference signals (DRSs) may not be sufficient for a UE to discover different cells in a heterogeneous network. The disclosed aspects provide approaches for managing cell IDs for various DRS configurations to improve UE discovery of different cells in heterogeneous networks. In an aspect, a UE receives a first reference signal (e.g., based on a PCI) configured for performing a base station measurement by the UE. The UE further receives one or more second reference signals (e.g., based on a VCI which is associated with the PCI) configured for measurement by the UE. The UE performs the base station measurement based on the first reference signal and the one or more second reference signals.

Abstract: Cell selection techniques are provided for network access to cells that may employ one or more coverage enhancement techniques. A user equipment (UE), which may be a machine type communication (MTC) device, upon initial acquisition or upon wakeup may measure a reference signal received power (RSRP), reference signal received quality (RSRQ), or both, and determine a cell selection value based at least in part on the RSRP, RSRQ, or a combination thereof. The cell selection value may be determined based on an offset, which may be selected based on a measurement accuracy capability of the UE. UE sequential access attempts, neighbor cell list information that may include coverage enhancement of neighboring cells transmissions, and cell re-selection measurement frequency adjustments are also described.

Abstract: Techniques are provided for aggregating carriers with different carrier configurations. The carriers may include both time division duplex (TDD) and frequency division duplex (FDD) carriers which may be configured such that control information for both carrier types is conveyed by the TDD carrier. In one aspect, an association between a set of subframes, including both TDD and FDD subframes, is determined. The association may operate to distribute control information for the FDD carrier over uplink subframes of the TDD carrier to achieve a load balancing. Alternatively, the association may operate to minimize a hybrid automatic repeat request (HARQ) feedback delay. The TDD carrier may provide resource grants for the aggregated carriers and the association may be used to identify subframes from both carriers which may be scheduled in a given DL subframe.

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.
