    Abstract: A user equipment (UE), a base station, a baseband processor or other network device can determine a codebook subset configuration of a plurality of multiple-input multiple-output (MIMO) layers for antenna ports of a codebook. The codebook subset configuration can include a nested structure based on a codebook configured for a fully-coherent UE, or a codebook configured for a partially-coherent UE. Fully-coherent precoders, a set of partially-coherent precoders or a set of non-coherent precoders can be configured in the codebook subset configuration to reduce a number of precoders from the partially-coherent precoders or the non-coherent precoders.

    Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCHs) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).
