1. A method of performing a reception of a physical downlink control channel (PDCCH) consisting of one or more control channel elements (CCEs) by a device for wireless communication, the method comprising:
receiving, through higher layer signaling, information including a resource element group (REG) bundle size for bundling REGs; and
performing, based on the higher layer signaling, a PDCCH reception in a control resource set, CORESET,
wherein each REG occupies 1 resource block (RB) in a frequency domain during 1 orthogonal frequency divisional multiplexing (OFDM) symbol in a time domain,
wherein the device is configured to assume that same precoding is used for REGs in a same REG bundle,
wherein an interleaved CCE-to-REG mapping is configured in the CORESET, and the REG bundle size is configured as one of a plurality of REG bundle sizes including i) REG bundle size=2 for bundling 2 REGs into 1 REG bundle and ii) REG bundle size=3 for bundling 3 REGs into 1 REG bundle, and
wherein, based on a CORESET duration configured for the CORESET being a 2-OFDM symbol length or a 3 OFDM symbol length in the time domain:
i) the REG bundle size=2 is configured, only for a CORESET duration with the 2-OFDM symbol length and
ii) the REG bundle size=3 is configured, only for a CORESET duration with the 3-OFDM symbol length.
