PDSCH PROCESSING TIME ENHANCEMENT TO SUPPORT UPLINK TRANSMIT SWITCHING

Abstract

Systems and methods for physical downlink shared channel (PDSCH) processing time enhancement to support uplink (UL) transmit (Tx) switching are described. In some embodiments, a PDSCH processing time, Tproc,1, is determined using an UL Tx switch processing time, Tswitch, corresponding to a physical uplink shared channel (PUSCH) preparation time, Tproc,2, used at a UE. In some embodiments, a Tproc,1 is determined using a PDSCH UL Tx switch processing time, Tswitch,PDSCH, that is determined using a Tswitch corresponding to a Tproc,2 used at a UE. In some embodiments, a Tproc,2 is compared to a time between an end of a downlink control information (DCI) scheduling a PDSCH and a beginning of a physical uplink control channel (PUCCH) having hybrid automatic repeat request acknowledgement (HARQ-ACK) signaling for a PDSCH to determine treatment of the PUCCH. In some embodiments, a d1,1 component of Tproc,1 is relaxed based on a Tswitch.
