Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure multiple phase tracking reference signal (PTRS) patterns in a single time interval (e.g., a slot) to improve phase tracking and phase noise estimation. The base station may transmit control signaling indicating multiple PTRS patterns for the time interval, and a user equipment (UE) may monitor for PTRSs in the time interval according to the indicated patterns to estimate a phase for receiving a downlink message from the base station. In some examples, the UE may signal a list of preferred PTRS patterns for the base station to use based on channel conditions. For example, the UE may transmit a report indicating one or more preferred PTRS patterns and a respective quantity of symbols in which the base station is to use each pattern.

Abstract: A receiving device may identify a mutual information associated with a code block. The receiving device may identify whether the code block is decodable based on the mutual information. The receiving device may skip decoding the code block if the code block is identified as being not decodable. The receiving device may decode the code block if the code block is identified as being decodable. The code block may be identified as being not decodable if the mutual information is less than a second threshold. The code block may be identified as being decodable if the mutual information is greater than the second threshold. The receiving device may identify the second threshold based on an MCS associated with the code block or a code block length of the code block.

Abstract: Methods, systems, and devices for wireless communications are described. Cyclic redundancy check (CRC) bits may be appended to a set of information bits on a per-group basis prior to encoding using an error correcting code. The amount of CRC bits appended to each group of information bits may be based on the priority of the group of information bits. For example, the priority may be based on the type of information conveyed by the group of information bits. For example, for a video stream, information bits conveying low frequency information may have a higher priority than information bits conveying high frequency information, as the low frequency bits may be more important to user perception/experience of the video. The transmitting device and the receiving device may negotiate the CRC configuration (e.g., the CRC bits per-group and the locations of the groups) so that the receiving device can verify the information bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, in a communication, an indication of a shaping filter to be used with one or more subsequent communications. The receiving device may receive the one or more subsequent communications having the shaping filter applied. Numerous other aspects are described.

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: 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.
