摘要： The present invention and its embodiments are made to provide for a feasible solution for determining transport block size in a wireless communication system. The method comprising of selecting plurality of transport block sizes near to the queue size of the user data and calculating the code rate for the plurality of selected transport block sizes and calculating code rate derived from Channel Quality Information (CQI) index. The method further comprising of comparing the code rates of the plurality of selected transport block sizes with the code rate derived from CQI index and filtering the selected transport block sizes having number of zero padding below a threshold value and having code rates equal or less than the code rate derived from CQI index and selecting one transport block for each modulation order from among the filtered transport block sizes which require lower number of Physical Resource Blocks (PRBs) to transmit. The method further comprising of determining one transport block size from among each modulation order by calculating the modulation order derived from CQI index to be used, such that the PRBs of the determined transport block size is less than a threshold value on comparison with the PRBs of other filtered transport block sizes having lower PRBs. The method further comprising of indicating the physical layer to transmit the user data with higher power if the modulation order of the determined transport block size is greater than the modulation order of the calculated modulation order derived from CQI.
