Method implemented by wireless transmitter / receiver (WTRU) and wireless transmitter / receiver (WTRU)

Abstract

The wireless transceiver unit (WTRU) can be configured to monitor the downlink physical control channel (PDCCH) candidates of the primary cell (PCell) and secondary cell (SCell). WTRU can be configured to determine the time interval for the PDCCH candidate group for the set of symbols based on the distance between the subcarriers associated with PCell and SCelL. WTRU can also be configured to determine the maximum number of PDCCH candidates to allocate for monitoring the search space of PCell and SCelL. The maximum number of PDCCH candidates can be based on the ratio per cell. WTRU can be configured to allocate PDCCH candidates to PCell's search space monitoring event and SCell's search space monitoring event based on a defined maximum number of PDCCH candidates. WTRU can also be configured to decode the allocated PDCCH candidates.
