    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit a multi-cell scheduling downlink control information (DCI) associated with at least two component carriers (CCs) for multi-cell communication with a user equipment (UE), the multi-cell scheduling DCI including a hybrid automatic repeat request (HARQ) process identification field that is based at least in part on a merged HARQ process space associated with the at least two CCs. The network node may receive HARQ feedback associated with the multi-cell communication, the HARQ feedback being based at least in part on the merged HARQ process space. Numerous other aspects are described.

    Abstract: Disclosed is a method of wireless communication. The method is performed at a first wireless node. The method comprises: obtaining a sequence of bits to be encoded, selecting a puncturing pattern from a plurality of puncturing patterns, generating, based on the sequence of bits to be encoded, a sequence of parity bits in accordance with a binary linear block coding scheme, puncturing, based on the selected puncturing pattern, at least one of the sequence of bits to be encoded or the sequence of parity bits, generating a plurality of modulation symbols based on remaining bits in the sequence of bits to be encoded and based on remaining bits in the sequence of parity bits, and transmitting, to a second wireless node, the plurality of modulation symbols.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.
