    Abstract: Aspects of the present disclosure provide techniques for a user equipment (UE) to set uplink power control for a long uplink burst and a short uplink burst. The UE receives uplink power control information including a first set of power control parameters for a long uplink burst and a second set of power control parameters for a short uplink burst with the sets of power control parameters being different from each other. The UE configures uplink power control for the long uplink burst based at least on the first set of power control parameters and the short uplink burst based at least on the second set of power control parameters. The UE sends at least one of a long uplink burst and a short uplink burst based on the corresponding uplink power control and sends at least one uplink power-headroom report for the long uplink burst and short uplink burst.

    Abstract: At times a UE may have a data transmission that needs to extend beyond a resource grant in an ULRB portion of a slot. The UE may receive resource region reservation information from a base station and determine when to extend an UL transmission from the ULRB portion of a slot into the ULCB portion of the slot based resource region reservation information. The resource region reservation information may indicate ULCB resources which are reserved for PUCCH, PRACH, PUSCH, SRS, or other transmissions. The UE may determine to refrain from extending the data transmission into the ULCB when at least a portion of the data transmission would overlap reserved resources as indicated by the resource region reservation information.

    Abstract: Certain aspects of the present disclosure provide techniques for processing reference and data signals for uplink transmission. A method is provided for wireless communications. The method generally includes obtaining different sets of samples for at least one of: a data signal or a reference signal; spreading the different sets of samples for the at least one data signal or reference signal using separate discrete Fourier transform (DFT) processing blocks; interlacing the spreaded sets of samples by assigning the spreaded sets of samples from each of the separate DFT processing blocks to equally spaced tones; and transmitting the at least one data signal or reference signal on the assigned tones in an orthogonal frequency division multiplexed (OFDM) symbol.

    Abstract: A wireless communications of a contention-based access procedure that reduces collision of reference signals (e.g., when multiple devices select a same reference signal) may support a relatively high user capacity. For a contention-based access procedure, a user equipment may select at least two reference signals and transmit those at least two reference signals in association with a payload to a base station . The payload may be demodulated using each of the at least two reference signals. Thus, if collision occurs with a first reference signal of the at least two reference signals, the payload may still be demodulated using a second reference signal of the at least two reference signals. A base station may demodulate the payload using either first reference signal or the second reference signal. The base station may transmit, to the wireless communications device, a response based on the demodulated payload.

    Abstract: A new design for an uplink control channel is provided. A User Equipment (UE) determines, based on a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, resources for transmitting the uplink control channel, and transmits the uplink control channel using the determined resources. A Base Station (BS) determines a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, and transmits information regarding the determined tone mapping pattern to at least one UE. The BS receives the uplink control channel based on the tone mapping pattern.

At a user equipment (UE), a method and apparatus may include receiving, from a network entity, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the network entity on the channel in accordance with the DMRS pattern. At a network entity, a method and apparatus may include transmitting, to a UE, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the UE on the channel in accordance with the DMRS pattern.
