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.

12. The method according to claim 8 , wherein the CSI request field has a non-zero value when either carrier aggregation is not configured or a Downlink Control Information (DCI) is transmitted in a search space specific to a cell.
13. The method according to claim 8 , wherein the total number of physical resource blocks N PRB allocated for the subscriber station is less than or equal to 4 when the CSI request field has a non-zero, two bit value set for CSI reporting.
14. The method according to claim 8 , wherein the total number of physical resource blocks N PRB allocated for the subscriber station is less than or equal to 4 when the CSI request field has a non-zero, one bit value set for CSI reporting.
15. A subscriber station, comprising: a transmitter configured to transmit Uplink Control Information (UCI) on a Physical Uplink Shared CHannel (PUSCH) to a base station when an uplink grant to the subscriber station includes: a modulation and coding scheme (MCS) of an enabled transport block (TB) with a value of 29, a channel state information (CSI) request field with a non-zero value, and a total number of physical resource blocks N PRB allocated for the subscriber station with a value less than or equal to a threshold number of physical resource blocks T PRB , wherein the threshold number of physical resource blocks varies based at least partly upon a number of downlink component carriers (DL CCs) reported in current CSI reporting.
16. The subscriber station according to claim 15 , wherein the CSI request field has a non-zero value when carrier aggregation is configured.
17. The subscriber station according to claim 15 , wherein the CSI request field has a non-zero value when either carrier aggregation is not configured.
18. The subscriber station according to claim 15 , wherein the CSI request field has a non-zero value when carrier aggregation is configured and a Downlink Control Information (DCI) is transmitted in a search space specific to the subscriber station.
19. The subscriber station according to claim 15 , wherein the CSI request field has a non-zero value when either carrier aggregation is not configured or a Downlink Control Information (DCI) is transmitted in a search space specific to a cell.
20. The subscriber station according to claim 15 , wherein the total number of physical resource blocks N PRB allocated for the subscriber station is less than or equal to 4 when the CSI request field has a non-zero, two bit value set for CSI reporting.
