Maximum achievable data rate (uplink) for a single user for a single OFDMA Resource Block in LTE-A

I am reading a paper related to resource and power allocation and I come across the formula for said title. Now the question is I could not find any formula for the finding the data rate using SINR. The formula used in the paper is below 

R = ln(1 + SINR_ijk);

where SINR_x is the SINR for a user i associated with cell j on a Resource block k

Where is this formula derived from ?

Solution

  • This appears to be a form of Shannon's Theorem. See more at Wiki link

    As an aside, this does not take into consideration coding rate, modulation and many other factors that affect data rate.

    (I would have made this a comment instead of an answer, but I do not have sufficient rep yet.)
