Aspects of a method and system for determining a limited soft buffer size on transport blocks for rate matching are provided. A data stream may be processed for transmission between a base station (eNodeB) and a UE via HARQ procedures. A two-stage rate-matching algorithm may be used in the HARQ procedures. A limited virtual soft buffer size at the UE in the two-stage rate-matching algorithm may be calculated on site based on channel condition information, available channel bandwidth, number of layers in spatial multiplexing, and the capacity of the UE, respectively. The data stream may be first rate-matched to the calculated limited soft buffer size available at the UE, and forwarded for second stage rate-matching to an actual physical channel size determined by the base station. The amount of bits forwarded for second stage rate-matching may equal to the calculated limited virtual soft buffer size of the virtual soft buffer.
