Provided are a method and apparatus for determining a transport block size (TBS) when transmitting a transport block through a PUSCH by applying transport block processing over multiple slots (TBoMS) in a wireless communication system. The UE determines the TBS based on the number of resource elements (N.sub.RE) allocated for the PUSCH, in this case, considers the number of slots for the TBoMS.

A first resource assignment can be transmitted in a first TTI. First downlink user data corresponding to at least a first transport block in the first TTI in a first set of resources for receiving a first portion of a first downlink user data and second set of resources receiving a second portion of the first downlink user data can be transmitted. The second set of resources can be configured for DCI and can be used instead for downlink user data and the second set of resources may not overlap with the first set of resources. A second resource assignment in a second TTI can be transmitted. Second downlink user data corresponding to at least a second transport block can be transmitted. The second downlink user data can be transmitted in the second TTI in third and fourth sets of resources.
