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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a time domain resource allocation (TDRA), in a unit of a time domain resource block (RB) or in a unit of a time domain RB group, for a communication that is to use a time domain waveform. The unit of the time domain RB or the unit of the time domain RB group may be a sub-symbol unit. The UE may communicate with the base station, using the time domain waveform, based at least in part on the TDRA for the communication. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for wideband uplink control channel capability indication during initial access are disclosed herein. A user equipment (UE) may transmit an uplink message indicating an uplink resource bandwidth capability of a physical uplink control channel (PUCCH) of the UE based on a power spectral density (PSD) limitation and a maximum transmission power of the UE. The UE may receive a downlink message indicating an uplink resource allocation of the PUCCH corresponding to the uplink resource bandwidth capability. Alternatively, the UE may receive a downlink configuration that indicates a first set of uplink resources and a second set of uplink resources. The UE may transmit an acknowledgment message in response to a downlink message of a random access channel process. The acknowledgment message includes the uplink resource bandwidth capability that indicates a selection between the first set of uplink resources and the second set of uplink resources.

Abstract: Wireless communications systems and methods related to multiplexing uplink control channel signals from different users are provided. A first wireless communication device obtains an uplink control channel multiplex configuration indicating a first frequency spreading sequence and at least one of a second frequency spreading sequence or a first spatial direction. The first wireless communication device communicates, with a second wireless communication device, a first uplink control channel signal including a first reference signal and a first uplink control information signal in a frequency spectrum based on the uplink control channel multiplex configuration. The first reference signal is based on the first frequency spreading sequence and the first uplink control information signal is based on at least one of the second frequency spreading sequence or the first spatial direction.
