Claim of US Patent No. 11,032,808

19. An apparatus for wireless communication, comprising:a processor;
memory in electronic communication with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
receive, at a user equipment (UE), signaling identifying a configuration for a control resource set in a slot, wherein the control resource set is split into a first component control resource set that comprises a first portion of the control information and a second component control resource set that comprises a second portion of the control information within a supported bandwidth of the UE, the first component control resource set being frequency diverse and time diverse from the second component control resource set;
receive, during the slot, a first demodulation reference signal (DMRS) from a base station in the first component control resource set and receive during the slot a second DMRS in the second component control resource set according to the configuration;
identify a mapping of one or more control channel elements (CCEs) associated with the control information, the mapping comprising each CCE of the one or more CCEs being mapped into a first component CCE associated with the first component control resource set and a second component CCE associated with the second component control resource set;
wherein the mapping comprises each component CCE being indexed sequentially in time within each of the first component control resource set and the second component control resource set, the component CCEs within each of the first component control resource set and the second component control resource set being permutated using the component CCE index and a random seed, and each component CCE in the first component control resource set and the second component control resource set being mapped according to the permutated component CCE index
and
receive, during the slot, control information in the first component control resource set and the second component control resource set according to the configuration.
