<p>The present invention provides a method and device for scheduling a physical downlink shared channel. The method comprises: acquiring a modulation and coding scheme (MCS) pre-used for scheduling and the size TBsize of a transport block (TB) required to be allocated to a user equipment; according to the MCS and an allocation situation of an RB resource allocated by the downlink, acquiring the maximum number of bits that the RB resource allocated by the system downlink is capable of providing; determining whether the TBsize is greater than the maximum number of bits, and if not, performing scheduling by using the MCS; otherwise, adjusting the RB, so that the TBsize after the adjustment is not greater than the maximum number of bits that the RB resource allocated by the downlink is capable of providing after the adjustment, and performing scheduling by using the MCS and the adjusted RB; or, adjusting the MCS, so that the TBsize after the adjustment is not greater than the maximum number of bits that the RB resource allocated by the downlink is capable of providing, and performing scheduling by using the adjusted MCS. Through the present invention, the coding rate of a PDSCH channel may be adjusted, and an effective coding rate of the PDSCH channel is reasonably selected to bear downlink user data, thereby improving the overall performance of an LTE system.</p> |
