1. A method for wireless communication at a user equipment (UE), comprising:
transmitting capability information comprising a parameter value, wherein the parameter value is a single bit that indicates a capability of the UE to read, and subsequently use, a radio resource control parameter from an access network entity, the radio resource control parameter identifying a first maximum number of layers that the access network entity will use to transmit to the UE, on a downlink, in at least one bandwidth part of a radio frequency (RF) spectrum band, wherein the first maximum number of layers comprises a maximum number of data streams for downlink transmissions, wherein the capability information comprises the parameter value if the UE has the capability to read, and subsequently use, the radio resource control parameter or lacks the parameter value if the UE lacks the capability to read, and subsequently use, the radio resource control parameter;
receiving, from the access network entity in response to the transmitted capability information comprising the parameter value that indicates the capability of the UE to read, and subsequently use, the radio resource control parameter, the radio resource control parameter identifying the first maximum number of layers that the access network entity will use to transmit to the UE;
configuring, based at least in part on receiving the radio resource control parameter from the access network entity that identifies the first maximum number of layers, a size of a soft buffer at the UE; and
receiving, according to the identified first maximum number of layers, signals from the access network entity using the at least one bandwidth part.
