No RB's are allocated for CQI and SR transmission, It uses the control channel which is PUCCH. PUCCH is control channel and no RB's allocated for this , entire ENB RB resource is assigned for PUSCH, But CQI/SR transmission used frequency domain resource index where in which symbol UE needs to send the CQI and SR information. These configuration is managed by two slots , because actual physical resource in 20Mhz is 200 RB's but ENB utilize only 100 RB's for PUSCH and remaining for these kind of control channels.
