Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node (e.g., BS, RU, etc.) transmits, to a second network node (e.g., UE, RU, etc.), indicates of precoding matrixes associated with bandwidth region with intervening bandwidth section(s). The second network node generates interpolated precoding matrix(es) associated with the intervening bandwidth section(s) via interpolation. The second network node performs uplink precoding intervening bandwidth section(s) based on the interpolated precoding matrix(es). The first network node receives transmission based on the uplink precoding.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication device may receive control signaling that indicates a change in one or more radio frequency thresholds for wireless signaling. The wireless communication device may perform, as part of an in-band clipping procedure, noise repetition and noise shaping to reduce a peak-to-average power ratio (PAPR) associated with the wireless signaling. The noise repetition and the noise shaping may include generating a set of values with one or more first values and one or more second values. The one or more first values may be associated with an error margin between a sample of a wireless communication signal and a clipping threshold. The one or more second values may be inversions of the one or more first values. The wireless communication device may apply the set of values to the wireless communication signal to reduce PAPR.

Abstract: A method of wireless communication by a user equipment (UE) includes converting a block of hybrid automatic repeat request acknowledgment (HARQ-ACK) bits from an original HARQ-ACK codebook into a partition, a number of partitions for a number of blocks corresponding to quantized HARQ-ACK bits. The method also includes transforming the quantized HARQ-ACK bits into a two part HARQ-ACK payload. The method further includes separately encoding a first part and a second part of the two part HARQ-ACK payload. The method also includes transmitting, to a network node, the encoded first part and the encoded second part.

Abstract: A method for wireless communication at a first wireless device and related apparatus are provided. In the method, the first wireless device communicates a first reference signal with a second wireless device based on a first frequency-modulated continuous wave (FMCW). The first wireless device further communicates a second reference signal with the second wireless device. The second reference signal is based on a second FMCW and has a second frequency bandwidth. The second frequency bandwidth is smaller than the first frequency bandwidth of the first reference signal, and the second reference signal has a frequency location based on the first reference signal. The first wireless device further communicates data with the second wireless device based on a channel estimation for a channel between the first wireless device and the second wireless device based on the second reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication device may implement a low-density parity-check (LDPC) code to encode and/or decode bits of a signal. The LDPC code may be defined by a base graph and a lifting scheme. The base graph may include check nodes and variable nodes. The lifting scheme may define a quantity of copies of the base graph used to generate the LDPC code and respective cyclic shifts associated with connected variable nodes and check nodes. The respective cycle shifts may be defined such that one or more cycles associated with a minimum length of the LDPC code are associated with a restriction on second degree variable nodes, nodes associated with least significant bits, or a combination thereof. Additionally, or alternatively, the respective cycle shifts may be defined such that a weighted girth of the LDPC code satisfies a threshold.

Abstract: Aspects of the disclosure involve multiplexing the transmission of communications signals and sensing signals at the resource element level. A frequency modulated continuous wave (FMCW) signal and plurality of orthogonal frequency-division multiplexing (OFDM) signals may be transmitted within an air interface frame structure having a plurality of resource elements, each resource element defined over a symbol duration in a time domain and a subcarrier in a frequency domain. The FMCW signal occupies a first plurality of resource elements and comprises a FMCW waveform repeated in the time domain and transmitted during a first symbol, over a first plurality of subcarriers of the air interface frame structure. The plurality of OFDM signals occupy a second plurality of resource elements in the air interface frame structure and are transmitted during the first symbol, over a second plurality of subcarriers of the air interface frame structure.

Abstract: A network node of a first radio access technology (RAT) may configure, from a set of resources available for dynamic spectrum sharing between the first RAT and a second RAT, a first subset of resources on which to communicate with one of rate matching or spatial domain multiplexing associated with the second RAT. A UE may receive, from a network node associated with the first RAT, information indicating a first subset of resources from a set of resources available for dynamic spectrum sharing between the first RAT and a second RAT with one of rate matching or spatial domain multiplexing. The network node and the UE may communicate on the first subset of resources from the set of resources with the one of rate matching or spatial domain multiplexing.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a message indicating UE assistance information (UAI). In some examples, the UE may transmit a request for network assistance information (NAI) for candidate cells. The UE may receive a control message indicating the NAI and a set of candidate cells for a conditional serving cell change. The UE may perform the conditional serving cell change based on the NAI for one or more candidate cells. In some examples, the UE may select a target cell from the set of candidate cells, and the UE may receive a control message indicating one or more coverage enhancement schemes supported by the target cell. The UE may perform a random access procedure based on the one or more coverage enhancement schemes supported by the target cell.
