Techniques for limiting blind decoding for multi-dci based multi-transmit-receive points

A method of wireless communication, comprising:

• receiving, by a user equipment (UE), a configuration of serving cells indicating a number of configured downlink serving cells without control resource set (CORESET) grouping or with one CORESET group and a number of configured downlink serving cells with two CORESET groups;
• determining, by the UE, a number of serving cells based on the configuration and a multiplication factor for serving cells with two CORESET groups, for signaling a number representing physical downlink control channel (PDCCH) monitoring capability across all downlink serving cells;
• determining, by the UE, a limit of a number of serving cells based on one of:
• (i) the configuration and the multiplication factor in response to the number representing PDCCH monitoring capability not to be signaled, or (ii) the number representing PDCCH monitoring capability in response to the number representing PDCCH monitoring capability to be signaled;
• determining, by the UE, a total limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group and a per cell limit of PDCCH candidates and non-overlapped CCEs to monitor in a slot per scheduled cell for cells without CORESET grouping or with one CORESET group and for cells with two CORESET groups based on the limit of the number of serving cells;
• and
• receiving a downlink control channel within a slot by performing blind decoding operations on CCEs up to the total limit and up to the per cell limit.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive a configuration of serving cells indicating a number of configured downlink serving cells without control resource set (CORESET) grouping or with one CORESET group and a number of configured downlink serving cells with two CORESET groups;
• determine a number of serving cells based on the configuration and a multiplication factor for serving cells with two CORESET groups, for signaling a number representing physical downlink control channel (PDCCH) monitoring capability across all downlink serving cells;
• determine a limit of a number of serving cells based on one of:
• (i) the configuration and the multiplication factor in response to the number representing PDCCH monitoring capability not to be signaled, or (ii) the number representing PDCCH monitoring capability in response to the number representing PDCCH monitoring capability to be signaled;
• determine a total limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group and a per cell limit of PDCCH candidates and non-overlapped CCEs to monitor in a slot per scheduled cell for cells without CORESET grouping or with one CORESET group and for cells with two CORESET groups based on the limit of the number of serving cells;
• and
• receive a downlink control channel within a slot by performing blind decoding operations on CCEs up to the total limit and up to the per cell limit.
