    Abstract: A node for wireless communication identifies a number of actually transmitted reference signals. The node identifies a number of available PRACH time-frequency resources and preamble indices in a time period. The node identifies a number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node determines that the available number of PRACH time-frequency resources or PRACH preamble indices within the time period is not an integer multiple of the product of the number of actually transmitted reference signals and the number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node maps the actually transmitted reference signals to the available PRACH time-frequency resources and preamble indices based on the identified information and determination.

    Abstract: To synchronize an apparatus during wireless communication, an apparatus may transmit a Random Access Channel (RACH) preamble sequence to a base station. However, care must be taken to prevent the RACH preamble sequence from causing inadequate levels of interference in other uplink resources. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine, based on a RACH subcarrier spacing and a data tone subcarrier spacing, a number of RACH tones allocated for a transmission of a RACH preamble sequence. In this manner, the apparatus may ensure that adequate uplink resources are allocated to prevent interference.

    Abstract: Aspects of the present disclosure provide a scheduling and transmission scheme to manage multiple uplink control information (UCI) resource grants for periodic and aperiodic UCI for a particular user equipment (UE). Grant selection rules may be defined to enable the UE to select one or more of the UCI resource grants allocated within a particular period of time. In addition, the grant selection rules may further enable the UE to combine both periodic and aperiodic UCI within a particular UCI resource grant. The grant selection rules may further enable the UE to multiplex UCI over multiple UCI resource grants. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Disclosed in this application are techniques to enabling and employing bandwidth agnostic tone mapping. Certain aspects of the present disclosure relate to methods and apparatus for mapping coded bits of a broadcast channel to tones of a symbol. Certain aspects of the present disclosure relate to methods and apparatus for mapping bits of a beamformed reference signal (BRS) signal to tones of a symbol. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system operating in millimeter wave (mmW) spectrum may utilize synchronization signals for beam tracking. A synchronization signal (e.g., primary synchronization signals (PSS), secondary synchronization signals (SSS), etc.), beam reference signal, and/or control signal may be designed to facilitate beam tracking. A synchronization signal structure based on a repeated sequence in the time domain may facilitate searching for different beams in a timely manner. In some cases, the repeated synchronization signal structure may be achieved by using a larger tone spacing, and hence having shorter symbol duration and repeating the short symbols in the time domain. The repeated structure may be further used to encode additional information (e.g., facilitated by the resulting additional degrees of freedom). Additionally or alternatively, a synchronization signal (e.g., SSS) may be discrete Fourier transform (DFT) pre-coded to achieve better peak-to-average-power-ratio (PAPR).
