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: Certain aspects of the present disclosure generally relate to wireless communications and more specifically to transmission resource management for ordered physical random access channel (PRACH) signals. An example method performed by a base station generally includes providing an indication of a set of transmission resources, within a narrowband region of a wider system bandwidth, for transmitting scheduled physical random access channel (PRACH) signals by a first user equipment (UE) and transmitting a command to the first UE to transmit a scheduled PRACH.

The first and second resource sets may be configured with a common reference signal configuration. The apparatus also configures first rate-matching parameters for the first resource set and second rate-matching parameters for the second resource set. Then, the apparatus transmits the first rate-matching parameters and the second rate-matching parameters and transmits the control channel using the first resource set and the second resource set.

Abstract: In order to reduce ambiguity in NB-SSS and complexity of receiver processing, a transmitter apparatus generates an SSS, wherein the SSS signal comprises a sequence of OFDM symbols, wherein each symbol of the sequence of SSS symbols is mapped to a codeword symbol of an FEC code. Source symbols of the sequence of SSS symbols carry a PCID and frame timing information, and parity symbols of the sequence of SSS symbols introduce redundancy and coding gain. A receiver receives the NB-SSS over multiple OFDM symbols, each symbol of the SSS comprising a short ZC sequence with a combination of root index and cyclic shift. The apparatus derives path metrics using cross-correlation for each of the plurality of symbols, determines a candidate SSS source message based on the derived path metrics and coding constraints of FEC codewords, and identifies a PCID and timing information based on the candidate SSS source message.

Abstract: The described aspects include methods and apparatus providing MTC in a wireless network. In an aspect, a narrow bandwidth within a wide system bandwidth is allocated for communicating data related to MTC. MTC control data generated for communicating over one or more MTC control channels for an MTC UE within the narrow bandwidth is transmitted over the one or more MTC control channels. The one or more MTC channels are multiplexed with one or more legacy channels over the wide system bandwidth. Other aspects are provided for transmission mode and content of the MTC control data or other MTC data.

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: The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK
