27. A method of wireless communication at a first network entity, comprising:
receiving, from a second network entity, downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission, wherein the PUSCH transmission comprises a first portion associated with a first subset of layers within a set of layers for transmission on a first beam based on a first set of parameters and a second portion associated with a second subset of layers within the set of layers for transmission on a second beam based on a second set of parameters;
mapping at least one transport block (TB) or at least one codeword (CW) to the first portion or the second portion based on the DCI or a radio resource control (RRC) configuration, wherein the DCI or the RRC configuration indicates between:
a first mode in which one TB or one CW is mapped to the first portion for transmission on the first beam and the second portion for transmission on the second beam, and
a second mode in which a first TB or a first CW is mapped to the first portion for transmission on the first beam and a second TB or a second CW is mapped to the second portion for transmission on the second beam; and
transmitting the at least one TB or the at least one CW to the second network entity, wherein when the DCI or the RRC configuration indicates the first mode, the one TB or the one CW is transmitted on both the first beam and the second beam, and when the DCI or the RRC configuration indicates the second mode, the first TB or the first CW is transmitted on the first beam and the second TB or the second CW is transmitted on the second beam.
