1、PUSCHPUSCHIn case of PUSCH available, control signaling is multiplexed with data on PUSCH. To cater for radio channel variation, link adaptation applies to data part Control signaling does not adopt adaptive modulation but the size of Res (resource elements) can change w.r.t varying radio conditionU
2、CI in PUSCHPDCCHThere is a fixed schedule relation between PDCCH in down link subFrame and PUSCH uplink subFrame (36.213 8 Physical uplink shared channel related procedures)For example configuration 1 : In subframe 1 ,the DCI will carry the UL grant for subframe 7 In subframe 4 ,the DCI will carry t
