Abstract
A method of providing a relaxed UE processing time for uplink transmission in NR is proposed. The UE processing time of uplink transmission is required for HARQ-ACK after the reception of downlink data over physical data shared channel (PDSCH). The UE processing time is also required for physical uplink share channel (PUSCH) transmission after the reception of an uplink grant. Under non-co-located carrier aggregation, the timing difference between the signals received at the UE in different cells could be up to 30.26 us, which increases the UE processing time for uplink transmission. In accordance with one novel aspect, the UE processing time requirement is relaxed according to the timing difference requirement for carrier aggregation, when CA is operated. In addition, the UE processing time requirement also depends on the applied subcarrier spacing (SCS) in NR systems.
