Abstract

A method implemented by an access node includes transmitting, by the access node to a user equipment (UE), a rate matching indicator indicating a rate matching buffer mode to set a size of a rate matching buffer; encoding, by the access node, data thereby producing encoded data; rate matching, by the access node, the encoded data in accordance with the size of the rate matching buffer; and transmitting, by the access node to the UE, the rate matched data.
