1. A method of wireless communication of a base station of a cell including a plurality of transmission reception points (TRPs), comprising:
sending, to a user equipment (UE), information indicating physical downlink control channel (PDCCH) monitoring occasions for the plurality of TRPs;
sending, to the UE, information indicating whether feedback across the plurality of TRPs is allowed;
sending, to the UE, an indication whether the feedback is for:
transport blocks associated with the PDCCH monitoring occasions, or
ode block groups of the transport blocks; and
receiving the feedback across the plurality of TRPs, in response to data transmissions to the UE, wherein a codebook size of the feedback across the plurality of TRPs is based on the PDCCH monitoring occasions, wherein the feedback is associated with a plurality of DCIs sent by the plurality of TRPs.
