Abstract: A base station may configure a user equipment (UE) with a subset of reference signal (RS) configurations among a set of RS configurations, and transmit a plurality of RSs based on the subset of RS configurations. The RS may be a demodulation RS (DMRS). The plurality of RSs may be configured to span each of the plurality of resource elements (REs) in the active bandwidth part (BWP). The UE may receive the plurality of RSs based on the subset of RS configurations and perform a spur detection based on the plurality of RSs received based on the subset of RS configurations. Each RS configuration of the set of RS configurations may be associated with at least one of the subset of RS configurations that is associated with the plurality of RSs spanning each of the plurality of REs in the active BWP.

Abstract: Aspects presented herein may enable a transmitting device, such as a base station, to compress tone reservation signaling for PAPR reduction, such that the transmitting device may indicate to a receiving device the location of reserved tones and data tones of a transmission with a small payload. In one aspect, a base station estimates an UL channel based on one or more SRSs from a UE, the estimated UL channel corresponding to a DL channel. The base station selects a plurality of TR locations associated with at least one of the DL channel or the UL channel. The base station transmits, to the UE, an indication of the plurality of TR locations associated with at least one of the DL channel or the UL channel.

Abstract: Methods, systems, and devices for wireless communications are described that provide for application of a tone reservation signal for orthogonal time-frequency space (OTFS) waveform communications. A tone reservation signal may use a first subset of resources of a set of resources associated with an OTFS frame, which may mitigate relatively large PAPR associated with transmission of the OTFS frame. A tone reservation signal may use in-frame resources (e.g., as delay-Doppler locations within a delay-Doppler resource grid) of the OTFS frame, or may use tone reservation resources may correspond subcarriers that are out-of-band with subcarriers of an OTFS frame. Signaling may be provided by a transmitting device that indicates the tone reservation resources, and a receiving device may decode a received communication in accordance with remaining resources other than the tone reservation resources.

Abstract: A method includes cellular vehicle-to-everything (CV2X) allocation collision detection and reporting. An allocation collision detection module detects control channel allocations from transmitting user equipments (UEs) in each time period of a group of time periods. A quantity of detected control channel allocations is determined in each time period. A report is then built and transmitted to at least one of the transmitting UEs. The report indicates collisions in each time period, based on the quantity and a location of the detected control channels in each time period, as well as based on a type of UE interface.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive, via a first frequency band, a first one or more signals of a communication that is associated with a multiple hop link, wherein the first one or more signals are associated with a first one or more communication parameters that result in a data capacity for the first one or more signals. The repeater may perform an action to adjust the first one or more communication parameters to a second one or more communication parameters for transmission via a second frequency band, the second one or more communication parameters causing the data capacity to be maintained. The repeater may transmit, via the second frequency band, a second one or more signals of the communication using the second one or more communication parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) and a base station implement reference signal modulation for conveying feedback information. In some examples, the UE may receive, from the base station, control signaling indicating to the UE to convey feedback information by modulating an uplink reference signal. The UE may receive, from the base station, a set of downlink messages. In some cases, the UE may transmit, to the base station, a set of uplink reference signals in response to receiving the downlink messages, where the set of uplink reference signals may be modulated by the UE to convey the feedback information. In some cases, the uplink reference signal may be a sounding reference signal (SRS) with embedded feedback information.

Abstract: A method of wireless communication by a user equipment (UE) includes reporting, to a base station, a requested downlink code block mapping, which has a defined duration. The method also includes receiving a first code block from the base station during the defined period of time. The method further includes receiving a second code block from the base station during the period of time. The method further includes decoding the first code block with a first demodulator according to the code block mapping. The method still further includes decoding the second code block with a second demodulator, which is different from the first demodulator, according to the code block mapping.

Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: A user equipment (UE) may transmit, to a network node, an indication of support for a decoder success prediction capability. The network node may obtain the indication of support by the UE for the decoder success prediction probability. The network node may output a transmission for the UE including one or more parameters based on the indication of support by the UE for the decoder success prediction capability. The UE may receive the transmission including one or more code blocks based on the indication of support for the decoder success prediction capability. The network node may optimize a multiple incremental redundancy scheme (MIRS) schedule for at least one of transmitting the transmission or retransmitting the transmission based on the indication of support by the UE for the decoder success prediction capability. The transmission may include the MIRS schedule.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for equalization domain selection at a wireless device. A wireless device may be configured to support a selection between time domain equalization and frequency domain equalization for receiving RF signals, which may be performed in accordance with detected channel conditions. For example, if a wireless device detects conditions associated with a relatively dispersive channel, the wireless device may select a frequency domain equalization and, if the wireless device detects conditions associated with a relatively flat channel, the wireless device may select a time domain equalization. In some implementations, performing a time domain equalization may include changing a sampling rate into a symbol rate, such as performing a resampling using a Farrow resampler. Such techniques may include a wireless device selecting an equalization scheme associated with a relatively lowest power consumption for detected channel conditions.
