A base station includes a transmit path circuitry to transmit an uplink grant in a DCI format to a subscriber station. The base station also includes a receive path circuitry to receive only UCI on a PUSCH from a subscriber station when the uplink grant includes a MCS of an enabled transport block (TB) with a value of 29, or a redundancy version of the PUSCH with a value of 1; a CSI request field with a non-zero value; and a total number of physical resource blocks allocated for the subscriber station, NPRB, with a value less than or equal to a threshold number of physical resource blocks, TPRB. TPRB is based at least partly upon one of a total number of CSI information bits to be transmitted on the PUSCH, Ntotal, and a number of DL CCs reported in a current CSI reporting, NCCs.
