Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.

Abstract: A method, a computer-readable medium, and an apparatus are disclosed. The apparatus may be a UE. The apparatus may transmit, to a base station, an indication of a UE capability for PDCCH monitoring. The apparatus may configure, based on the UE capability for PDCCH monitoring, first MOs of a USS set to align with second MOs of a CSS set. The apparatus may monitor, based on the configuration, for a plurality of PDCCHs during PDCCH MOs. The PDCCH MOs may correspond to the first MOs or the second MOs. The first MOs of the USS set may be adjusted dynamically to be in same slots as the second MOs of the CSS set or to be within a predefined range of the second MOs of the CSS set.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives an initial transmission of a common codeword and a private codeword. The common codeword is common to the UE and at least one other UE. The private codeword is directed to the UE. An acknowledgement is transmitted indicative of decoding results of the common codeword and the private codeword based on results of whether the common codeword was successfully decoded and whether the private codeword was successfully decoded. At a Network Entity (NE), an initial transmission of the common codeword and the private codeword is sent and an acknowledgement is received indicative of decoding results. At least one of the common codeword or the private codeword can be retransmitted depending on the acknowledgement.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device allocated two sets of non-contiguous frequency domain resources may divide a set of modulation symbols associated with a codeword into two subsets of modulation symbols. The wireless device may map the two subsets of modulation symbols into two sets of pre-discrete Fourier transform (DFT) resource elements (REs). The wireless device may pad the pre-DFT REs according to a block based scheme or a comb based scheme. The wireless device may perform a first DFT on the first set of pre-DFT REs and a second DFT on the second set of pre-DFT REs to generate first and second sets of frequency domain samples. The wireless device may perform an inverse fast Fourier transform on the first and second sets of frequency domain samples to generate a time domain waveform that may have a low peak to average power ratio.
