Claim of US Patent No. 10,694,513

1. A method for receiving a downlink control signal by User Equipment (UE) in wireless communication that includes a Base Station (BS), the method comprising:receiving, by the UE from the BS, a first information related to an initial value of a first DeModulation Reference Signal (DMRS) scrambling sequence and a second information related to an initial value of a second DMRS scrambling sequence;
based on the first information, receiving, by the UE from the BS, a first Physical Downlink Control Channel (PDCCH) in a first PDCCH-related resource;
based on the second information, receiving, by the UE from the BS, a second PDCCH in a second PDCCH-related resource,
wherein the second PDCCH-related resource is different from the first PDCCH-related resource,
receiving, by the UE from the BS, a first Physical Downlink Shared CHannel (PDSCH) based on the first PDCCH; and
receiving, by the UE from the BS, a second PDSCH based on the second PDCCH,
wherein the initial value of the first DMRS scrambling sequence is configured to the first PDCCH-related resource and the initial value of the second DMRS scrambling sequence is configured to the second PDCCH-related resource.
