Systems and methods for supporting multiple allocations in UL/DL grant for a 5G NR UE and gNB

A base station apparatus comprising:

• a transmitting circuitry and a generating circuitry, wherein
• the transmitting circuitry is configured to:
• transmit, to a user equipment (UE), by a radio resource control message, first information used for configuring a monitoring occasion for a UE-specific search space where the UE monitors a physical downlink control channel (PDCCH) in the UE-specific search space;
• and
• transmit, to the UE, by the radio resource control message, second information used for configuring downlink control information (DCI) formats in accordance with which the UE monitors the PDCCH in the UE-specific search space,
• the generating circuitry is configured to generate the first information and the second information,
• the monitoring occasion for the UE-specific search space corresponds to a position of a slot and a position of a symbol, and
• the DCI formats comprise a DCI format used for scheduling of a physical uplink shared channel (PUSCH) in one cell and a DCI format used for scheduling of a physical downlink shared channel (PDSCH) in one cell
• the transmitting circuitry is further configured to:
• transmit, to the UE, by the radio resource control message, third information used for configuring a monitoring occasion for a common search space where the UE monitors a PDCCH in the common search space;
• and
• transmit, to the UE, by the radio resource control message, fourth information used for configuring a DCI format in accordance with which the UE monitors the PDCCH in the common search space, the DCI format being a DCI format with cyclic redundancy check scrambled by a temporary cell-radio network temporary identifier (Temporary C-RNTI), the DCI format being used for scheduling of a PUSCH, wherein
• the monitoring occasion for the common search space corresponds to a position of a slot and a position of a symbol.

A communication method of a user equipment (UE) comprising:

• receiving, by a radio resource control message, first information used for configuring a monitoring occasion for a UE-specific search space where the UE monitors a physical downlink control channel (PDCCH) in the UE-specific search space;
• and
• receiving, by the radio resource control message, second information used for configuring downlink control information (DCI) formats in accordance with which the UE monitors the PDCCH in the UE-specific search space, wherein
• the monitoring occasion for the UE-specific search space corresponds to a position of a slot and a position of a symbol, and
• the DCI formats comprise a DCI format used for scheduling of a physical uplink shared channel (PUSCH) in one cell and a DCI format used for scheduling of a physical downlink shared channel (PDSCH) in one cell,
• the method further comprising:
• receiving, by the radio resource control message, third information used for configuring a monitoring occasion for a common search space where the UE monitors a PDCCH in the common search space;
• and
• receiving, by the radio resource control message, fourth information used for configuring a DCI format in accordance with which the UE monitors the PDCCH in the common search space, the DCI format being a DCI format with cyclic redundancy check scrambled by a temporary cell-radio network temporary identifier (Temporary C-RNTI), the DCI format being used for scheduling of a PUSCH, wherein
