Adaptation of the number of nr pdcch candidates

A user equipment (UE) for receiving downlink control information (DCI) on a physical downlink control channel (PDCCH) via wireless communication, comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the processor is configured to:
• receive a configuration of the PDCCH;
• determine a number of downlink PDCCH candidates and a number of uplink PDCCH candidates within a search space based on the configuration, wherein the number of downlink PDCCH candidates is different than the number of uplink PDCCH candidates, and a length of each downlink PDCCH candidate is different than a length of each uplink PDCCH candidate;
• and
• blindly decode the search space with each PDCCH candidate as a hypothesis to determine whether any of the downlink PDCCH candidates or uplink PDCCH candidates decode to a DCI format.

• means for receiving a configuration of the PDCCH;
• means for determining a number of downlink PDCCH candidates and a number of uplink PDCCH candidates within a search space based on the configuration, wherein the number of downlink PDCCH candidates is different than the number of uplink PDCCH candidates, and a length of each downlink PDCCH candidate is different than a length of each uplink PDCCH candidate;
• and
• means for blindly decoding the search space with each PDCCH candidate as a hypothesis to determine whether any of the downlink PDCCH candidates or uplink PDCCH candidates decode to a DCI format.

A non-transitory computer-readable medium storing computer code executable by a processor for receiving downlink control information (DCI) on a physical downlink control channel (PDCCH) via wireless communications, comprising code to:

• receive a configuration of the PDCCH;
• determine a number of downlink PDCCH candidates and a number of uplink PDCCH candidates within a search space based on the configuration, wherein the number of downlink PDCCH candidates is different than the number of uplink PDCCH candidates, and a length of each downlink PDCCH candidate is different than a length of each uplink PDCCH candidate;
• and
• blindly decode the search space with each PDCCH candidate as a hypothesis to determine whether any of the downlink PDCCH candidates or uplink PDCCH candidates decode to a DCI format.
