    Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink common burst symbol waveform selection and configuration. A waveform for the uplink common burst symbol may be selected to be a single-carrier frequency division multiplexing (SC-FDM) waveform, an orthogonal frequency division multiplexing (OFDM) waveform, or combinations thereof, based at least in part on information that is to be transmitted. A pattern for SC-FDM sequences may be selected to provide enhanced channel estimation through common pilot tones across different sequences, wideband or narrowband sequences may be selected based at least in part on information to be transmitted, and acknowledgment feedback may be transmitted in an end portion of the uplink common burst symbol in some cases to provide additional processing time for determining the acknowledgment feedback.

    Abstract: Wireless communication devices, such as a scheduled entity, are adapted to facilitate uplink transmissions on multiple physical uplink control channels (PUCCHs) of a regular burst period. According to one example, a scheduled entity may obtain a payload for an uplink transmission on a PUCCH. The scheduled entity may subsequently send the uplink transmission utilizing two or more physical uplink control channels (PUCCH) of a regular burst period, where each PUCCH is associated with a different frequency band of the regular burst period. According to one example, a scheduling entity may receive an uplink transmission, where the uplink transmission utilizes a first PUCCH of a regular burst period, and at least a second PUCCH of the regular burst period, each of the first and second PUCCHs being associated with respectively different frequency bands of the regular burst period. Other aspects, embodiments, and features are also included.

    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.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that may be configured to receive a downlink control message, to determine a beta offset value for transmitting UCI based at least in part on the downlink control message, and to transmit the UCI on an uplink shared channel interleaved with data based on the determined beta offset value. The apparatus may identify the beta offset from a set of values based on the downlink control message. An apparatus may identify resources allocated for PUSCH and may map UCI to the identified resources for PUSCH in a frequency interleaved manner over a bandwidth of the identified resources. The apparatus may map data to the identified resources in a time-first or frequency-first manner, and may transmit a signal comprising UCI and data on the identified resources of the PUSCH in accordance with the mapping.

    Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support flexible symbol configurations for uplink channels. In one example a method includes performing transmitting first uplink information from a subordinate entity to a scheduling entity in a long burst portion of one or more slots, and transmitting second uplink information from the subordinate entity to the scheduling entity in a combination of long burst and short burst portions of the one or more slots. Each of the one or more slots includes a portion that carries a physical downlink control channel. The second uplink information is transmitted in a physical uplink control channel.

    Abstract: Adjacent channel leakage-power ratio (ACLR) can be reduced at a transmitter of a device. A modulated signal can be mapped into a plurality of tone sets in a frequency domain, wherein the plurality of tone sets include a first, a second, and a third set of tones. The first and the third set of tones can be converted in the frequency domain to a fourth and a fifth set of tones, respectively, in a time domain. A zero padding of one or more symbols associated with the fourth and the fifth set of tones can be performed to output a sixth and a seventh set of tones, respectively. The sixth and the seventh set of tones can be converted to an eighth and a ninth set of tones, respectively, in the frequency domain. The eighth and the ninth set of tones can be processed for transmitting to another wireless device.
