A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) system may be configured for multi physical downlink shared channel (PDSCH) scheduling and may decode a first downlink control information (DCI) and a second DCI received from a gNodeB (gNB). The first DCI may schedule multiple PDSCHs and the second DCI may schedule one or more PDSCHs. The UE may check the timing relations of the scheduled PDSCHs for validity when the first DCI and the second DCI end at a same symbol. When the multiple PDSCHs scheduled by the first DCI and the one or more PDSCHs scheduled by the second DCI are determined to have overlapping time spans, the UE may identify all the PDSCHs scheduled by the first DCI the second DCI as invalid.

Method and apparatus for transmitting data

A generation-Node B (gNB) configured for unlicensed spectrum operation above 52.6 GHz in a fifth-generation new-radio (NR) system (5GS) may encode a parameter (e.g., ssb-PositionsInBurst) for transmission to a UE (e.g., in the SIB1 or UE specific RRC signalling). The parameter may indicate candidate positions of synchronization signal blocks (SSBs) within a discovery reference signal (DRS) measurement timing configuration (DMTC) transmission window within slots of a system frame (SFN). During the DMTC window, the gNB may perform a LBT procedure on an unlicensed carrier of the unlicensed spectrum to determine if the unlicensed carrier is available. When the LBT is successful (i.e., the unlicensed carrier is available), the gNB may encode a discovery reference signal (DRS) for transmission on the unlicensed carrier. The DRS may include one or more of the SSBs transmitted during the candidate positions that fall within the DRS. The gNB may perform rate matching around the SSBs for a scheduled PDSCH based on the indicated parameter and transmit the rate-matched PDSCH.
