    Abstract: Methods, systems, and devices for wireless communication are described for defining uplink control channel resources and mapping uplink control channel resources to a user equipment (UE). Approaches described herein include identifying a physical uplink control channel (PUCCH) format to be used for a subsequent PUCCH transmission by the UE, identifying a PUCCH resource mapping rule based at least in part on the PUCCH format, and determining an uplink transmission resource to be used for the subsequent PUCCH transmission based at least in part on the PUCCH resource mapping rule. The PUCCH resource mapping rule may be explicit and/or implicit.

    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a power headroom report for multiple radio access technologies (RATs). A user equipment (UE) may support multiple RATs that correspond to different transmission time intervals (TTIs). A UE may determine a reporting schedule for power headroom reports (PHRs) for a first RAT and a second schedule for PHRs for a second RAT. The UE may generate a PHR for the first RAT and a companion PHR for the second RAT, and may transmit the PHR and companion PHR based at least in part on the first PHR schedule. In some examples, the UE may receive a PHR type from the base station, and may determine a joint PHR based on the type. The UE may determine a joint PHR schedule based on a granularity of supported RATs.

    Abstract: Transmit diversity schemes may be used for sending sequence-based signals over multiple antennas. For example, a user equipment (UE) may determine an uplink sequence to be transmitted to a base station using multiple antennas. The UE may utilize a transmit diversity scheme for the multiple-antenna transmission of the uplink sequence, where the transmit diversity scheme utilized may be based on a number of symbol periods during which the sequence is transmitted. In accordance with the transmit diversity scheme, the UE may use multiple transmit antennas to transmit different sequences from respective antennas. In other examples, the UE may transmit the uplink sequence using different time or frequency resources. Additionally, the UE may use some combination of different transmit diversity schemes for sequence-based signals. In some aspects, the base station may provide an indication of the transmit diversity scheme that the UE is to use for transmitting the uplink sequence.

    Abstract: Some techniques and apparatuses described herein may assign resource elements of a particular resource block for transmission by two or more different antennas in a fashion such that the symbols are interleaved in frequency and/or in time, which improves frequency diversity of the two or more different antennas, thereby improving uplink performance of the UE. In some aspects, when the two or more resource blocks are contiguous, then each antenna may produce an interleaved frequency division multiple access (IFDMA) waveform, which may maintain peak to average power ratio (PAPR) properties of a single channel FDMA transmission. Thus, some techniques and apparatuses described herein may achieve transmit diversity and/or frequency diversity of a stream of symbols on two or more antennas without significantly increasing the PAPR of the stream of symbols.

    Abstract: Methods, systems, and devices for wireless communications are described that support frequency and time domain multiplexing for low peak-to-average waveforms with multiple streams. A user equipment (UE) may identify sets of symbols associated with different streams (e.g., multiple single-carrier discrete Fourier transform (DFT)-spread waveforms), where each stream may be associated with a low peak-to-average power ratio (PAPR). In some cases, different waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM). The UE may further reduce the PAPR of the multiplexed waveforms by performing time division multiplexing (TDM) across the single-carrier streams, and sets of symbols that are not used by one waveform may be used by another waveform. Frequency domain phase ramps may be applied to align the multiplexed waveforms. Signals included in an uplink transmission according to these techniques may maintain properties similar to single-carrier waveforms, including a low PAPR.

    Abstract: Multiple-input, multiple-output (MIMO) devices and non-MIMO devices may implement a flexible comb-based design for transmission of reference signals, such as demodulation reference signals (DMRSs). User equipment (UEs) of different ranks may use the flexible comb-based design to transmit the reference signals in a common comb pattern within an allocated bandwidth. UEs using as many antenna ports as combs in the common comb pattern may transmit a different reference signal using a different antenna port over each comb, while UEs using fewer antenna ports than combs may concatenate combs, so that the UEs may transmit a reference signal using a single antenna port over multiple combs. Using the flexible comb-based design, a base station may be capable of better manage inter-cell interference and multiplexing of different rank UEs in shared resource blocks (RBs) may be supported.

    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.
