Abstract: Certain aspects of the present disclosure generally relate to downlink (DL) based and uplink (UL) based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as narrowband Internet of Things (NB-IoT) devices. An exemplary method that may be performed by a node includes monitoring for positioning reference signals (PRS) transmitted from one or more base stations within a narrowband region of a wider system bandwidth, wherein tones of the PRS are repeated across at least one of multiple symbols within a same subframe, or multiple consecutive subframes, and estimating timing from the one or more base stations based on the PRS.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to design principles for extending Internet of Things (IoT) (e.g., narrowband IoT (NB-IoT), machine type communication(s) (MTC), etc.) into an unlicensed radio frequency (RF) band spectrum. In certain aspects, the method generally includes determining an interlace structure of tones, within an unlicensed radio frequency (RF) spectrum, available to a wireless node for communication, and communicating based on the interlace structure. In some aspects, the communicating involves hopping between tones within the interlace structure during different communication intervals.

Abstract: Systems and methodologies are described that facilitate indicating a type of waveform utilized for uplink transmission in a wireless communication environment. An access terminal can select a type of waveform from a set of possible waveform types. Moreover, a reference signal can be generated based upon the selected type of waveform. For instance, a sequence employed to yield the reference signal can be generated and/or chosen as a function of the selected type of waveform. According to another illustration, a tone location and/or a symbol location of the reference signal can be based upon the selected type of waveform. Further, the reference signal can be sent as part of the uplink transmission to the base station from the access terminal. The base station can detect the selected type of waveform utilized by the access terminal for the uplink transmission based upon parameter(s) recognized from the reference signal.

Abstract: The apparatus improves HD-FDD data transmission rates, e.g., for eMTC by using a self subframe scheduling PDSCH that overlaps a M-PDCCH transmission in time. The apparatus may communicate using ACK(s)/NACK(s) for multiple HARQs that are bundled and/or multiplexed within a subframe in order to increase a number of HARQs.

Abstract: Various aspects described herein relate to communicating using a configurable bandwidth. A user equipment (UE) can receive a control channel from a serving evolved Node B (eNB), where the control channel includes a resource grant for an uplink shared data channel including a number of resource block groups starting from a starting resource block group in an allocation space, and where the allocation space includes a plurality of resource block groups in a frequency domain over a plurality of symbols in a time domain. The UE can transmit data in the uplink shared data channel starting from the starting resource block group in the allocation space and continuing through the number of resource block groups in the allocation space over the frequency domain first and over the time domain second.

Abstract: Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).

Abstract translation: 公开了用于发送控制信息以支持多分量载波（CC）上的操作的技术。 用户设备（UE）可以配置有多个用于载波聚合的CC。 多个CC可以与不同的上行链路 - 下行链路配置相关联，并且可以具有不同的下行链路子帧和上行链路子帧。 在一个方面，可以基于用于PCC的UCI传输时间线（而不是基于SCC的UCI传输时间线）在主CC（PCC）上发送用于辅助CC（SCC）的上行链路控制信息（UCI）。 例如，可以基于PCC的下行链路许可传输时间线来发送用于SCC的下行链路许可。 在另一方面，可以基于PCC的上行链路授权传输时间线（而不是基于SCC的上行链路许可传输时间线）在PCC上发送用于SCC的上行链路许可。
