Draft: this limits PUCCH payload to 11 bits, 7 CSI + 3 ACKNACK + 1 SR maximum.
hotfix for improving DL performance. It seems that decoding of more than 11-bits on PUCCH format 2 is not reliable and this limits DL throughput significantly on 100 MHz channels. This limits the PUCCH2 payload to 7 bits CSI + 3 ACKNACK + 1 SR bits maximum on PUCCH format 2.
