Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a capability report indicating one or more capability parameters that are associated with wideband interference measurement of an orthogonal frequency division multiplexing (OFDM) channel and a supported subband size for the OFDM channel. The UE may receive, from the network node, configuration information indicating an interference measurement resource associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a greater number of frequency domain resources than the supported subband size. The UE may measure, based on the reception of the configuration information, the interference measurement resource to obtain interference measurement information associated with the OFDM channel. The UE may transmit, to the network node, a measurement report indicating the interference measurement information. Numerous other aspects are described.

Abstract: A method for wireless communication at a transmitting wireless device and related apparatus are provided. In the method, the device determines, based on the first parameter associated with a Forward Error Correction (FEC) process and a second parameter associated with a probabilistic shaping process, the transport block (TB) size for a TB associated with a signal to be transmitted, and performs the probabilistic shaping process on a first set of data bits of the signal on the TB to obtain a second set of transmit bits. The TB cyclic redundancy check (CRC) is inserted into the TB before or after the probabilistic shaping process, and the probabilistic shaping process is applied on the TB level across multiple code blocks (CBs) associated with the TB or on the CB level individually inside each CB of the multiple CBs. The device further transmits the signal using the second set of transmit bits.

Abstract: Apparatuses and methods for scrambling of FMCW for interference mitigation in JCS are described. An apparatus is configured to obtain a set of phase-coded FMCW signals that is phase-coded based on a scrambling ID for the first node and/or a second node. The apparatus is configured to descramble the set of phase-coded FMCW signals based on the scrambling ID. The set of phase-coded FMCW signals is descrambled to obtain a set of descrambled FMCW signals. The apparatus is configured to perform sensing, communication, and/or JCS functions based on the set of descrambled FMCW signals. Another apparatus is configured to configure a set of FMCW signals, and to scramble the set of FMCW signals based on a scrambling ID for the first node and/or a second node to obtain a set of phase-coded FMCW signals. The apparatus is configured to transmit, for the second node, the set of phase-coded FMCW signals.
