Abstract: Aspects of the disclosure relate to selection and use of peak reduction tones (PRTs) including obtaining a predetermined sequence of PRTs corresponding to a set of granted resources including a plurality of tones, mapping a set of data to a first subset of the plurality of tones outside of the predetermined sequence of PRTs and mapping a set of PRTs to a second subset of the plurality of tones within the predetermined sequence of PRTs. At least one peak of a time domain representation of the first subset of the plurality of tones is canceled using a time domain representation of the second subset of the plurality of tones. A transmitted waveform comprising the first subset of the plurality of tones and the second subset of the plurality of tones is transmitted.

Abstract: Aspects presented herein may enable a wireless device to use periodic reserved resources to serve aperiodic traffic over sidelink. In one aspect, a wireless device reserves a set of periodic resources for sidelink transmission, where the reserved set of periodic resources include reserved resources for SCI and reserved resources for data. The wireless device transmits SCI without a data transmission in a periodic resource for the period. In another aspect, a first wireless device receives a reservation from a second wireless device for a set of periodic resources for sidelink transmission. The first wireless device receives, from the second wireless device, SCI in a period of the periodic resources, the SCI including an indication that the SCI is not associated with a data transmission.

Abstract: A transmitting device communicates with a receiving device an indication to apply PAPR reduction for a data transmission. The transmitting device applies a first PAPR reduction signal and a second PAPR reduction signal to the data transmission to reduce at least one signal peak of the data transmission to yield a transmission signal, where the first PAPR reduction signal includes a first set of PRTs that does not overlap with data tones and the second PAPR reduction includes a second set of PRTs that overlaps with the data tones and does not overlap with reserved tones. The transmitting device transmits the transmission signal to the receiving device.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described According to one or more aspects of the present disclosure, a user equipment (UE) may receive an uplink grant of an uplink transmission from the UE to the base station. The UE may identify a packet transmission mode indicated in the uplink grant. The indication may specify whether the UE is to transmit the uplink transmission using a default mode, such as a first-in first-out mode, or a packet-group transmission mode. The UE may determine packets for inclusion in a transmission payload for the uplink transmission based on the identified transmission mode and transmit the uplink transmission in accordance with the packet transmission mode and the uplink grant.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may associate a first and second port with a set of antenna elements based on a first and second linear precoding vector. The base station may generate coefficients indicating a first combination and a second combination of a first data set for a first user equipment (UE) and a second data set for a second UE. The base station may apply the first and second linear precoding vectors to the first and second combinations, respectively, transmit a first demodulation reference signal (DMRS) and a second DMRS using a first comb corresponding to the first and second ports, and transmit at least a third DMRS indicating the coefficients using a second comb. The UEs may extract data from the precoded combinations by applying the coefficients and estimating channels associated with the first and second DMRS.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.
