Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a demodulation reference signal (DMRS) and perform a filtering procedure on frequency-domain symbols of the DMRS to obtain a frequency-domain noise signal associated with the frequency-domain symbols. The UE may perform a spur detection procedure on the frequency-domain noise signal to detect one or more frequency spurs associated with the frequency-domain symbols. In addition, the UE may estimate a frequency of the frequency spurs. In some implementations, the UE may transmit information indicating spur parameters associated with the frequency spurs (e.g., including the estimated frequency) to a network entity. The UE may receive a control message indicating a rate matching pattern for subsequent communications, the rate matching pattern based on the spur parameters. The UE and the network entity may communicate according to the rate matching pattern.

Spur detection, estimation, and mitigation

An apparatus may be configured to receive a polar-encoded transmission comprising at least one intermediate node associated with a first configuration of frozen leaf nodes and information leaf nodes. The apparatus may further be configured to apply an FHT to a first set of values associated with a first intermediate node of the at least one intermediate node to generate a second set of values associated with the first intermediate node. The apparatus may also be configured to select, based on the second set of values, one or more paths associated with the first intermediate node for a SSCL decoding. The apparatus may further be configured to calculate a path metric for each of the selected one or more paths associated with the first intermediate node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates a transmission parameter associated with a random access response (RAR) type; transmit a random access message associated with the RAR type; use the transmission parameter to obtain a physical downlink control channel (PDCCH) communication that schedules a physical downlink shared channel (PDSCH) communication that includes a RAR in a medium access control protocol data unit of the PDSCH communication; and obtain or refraining from obtaining the PDSCH communication based at least in part on whether the PDCCH communication is successfully obtained using the transmission parameter. Numerous other aspects are provided.
