Scheduling on a cell from different cells

A user equipment (UE) comprising:

• a transceiver configured to receive:
• first information for first and second scheduling cells of a scheduled cell, and
• second information for receptions of physical downlink control channels (PDCCHs) from the first and second scheduling cells, wherein:
• the PDCCHs provide downlink control information (DCI) formats with cyclic redundancy checks (CRCs) scrambled by:
• a cell radio network temporary identifier (C-RNTI), a configured scheduling RNTI (CS-RNTI), or a modulation and coding scheme C-RNTI (MCS-C-RNTI), and
• the DCI formats schedule physical uplink shared channel (PUSCH) transmissions, or physical downlink shared channel (PDSCH) receptions, on the scheduled cell;
• and
• a processor operably coupled to the transceiver, the processor configured to determine whether reception of the PDCCHs is either only from the first scheduling cell or only from the second scheduling cell within a time unit based on the second information,
• wherein the transceiver is further configured to receive the PDCCHs either only from the first scheduling cell or only from the second scheduling cell within the time unit.

A base station comprising:

• a transceiver configured to transmit:
• first information for first and second scheduling cells of a scheduled cell, and
• second information for receptions of physical downlink control channels (PDCCHs) from the first and second scheduling cells, wherein:
• the PDCCHs provide downlink control information (DCI) formats with cyclic redundancy check (CRC) scrambled by:
• a cell radio network temporary identifier (C-RNTI), a configured scheduling RNTI (CS-RNTI), or a modulation and coding scheme C-RNTI (MCS-C-RNTI), and
• the DCI formats schedule physical uplink shared channel (PUSCH) transmissions, or physical downlink shared channel (PDSCH) receptions, on the scheduled cell;
• and
• a processor operably coupled to the transceiver, the processor configured to determine whether transmission of the PDCCHs is either only from the first scheduling cell or only from the second scheduling cell within a time unit according to the second information,
• wherein the transceiver is further configured to transmit the PDCCHs either only from the first scheduling cell or only from the second scheduling cell within the time unit.
