transmits, through the GC-PDCCH in the time slot, control information related to the data in the previous time slot; and
transmits information of a downlink transmission termination position for an unlicensed spectrum through the GC-PDCCH in a third time slot that is different from than both the previous time slot and the time slot,
wherein the downlink transmission termination position either is indicated in the GC-PDCCH directly, or is determined according to slot format information included in the GC-PDCCH, and
wherein the processing circuit transmits the data in the previous time slot of the time slot where the GC-PDCCH is located according to a default time slot format.
2. The electronic device according to claim 1 , wherein the control information is used to indicate at least one of a modulation and coding scheme (MCS) level of the data or time slot format related information (SFI) of the data.
3. The electronic device according to claim 1 , wherein the processing circuit transmits, through the GC-PDCCH, time slot format related information (SFI) of the third slot indicating where the downlink transmission termination position is located.
4. The electronic device according to claim 1 , wherein the processing circuit transmits the control information related to the data in the previous time slot through the GC-PDCCH when the control information related to the data in the previous time slot is not transmitted in the previous time slot.
5. The electronic device according to claim 1 , wherein the processing circuit transmits a notification to a user equipment such that the user equipment receives the control information related to the data in the previous time slot through the GC-PDCCH.
6. The electronic device according to claim 5 , wherein the processing circuit transmits the notification to the user equipment through a licensed spectrum.
7. The electronic device according to claim 1 , wherein the processing circuit reconfigures a transmission period of the GC-PDCCH to a user equipment.
8. The electronic device according to claim 7 , wherein the processing circuit transmits the reconfigured transmission period of the GC-PDCCH to the user equipment through a licensed spectrum.
9. The electronic device according to claim 1 , wherein the electronic device is a network side device in a New Radio (NR) communication system.
10. An electronic device operating in a mobile device and comprising a processing circuit that:
receives, from a base station, data in a previous time slot of a time slot where a Group Common-Physical Downlink Control Channel (GC-PDCCH) is to be received;
receives, through the GC-PDCCH in the time slot, control information related to the data in the previous time slot; and
receives information of a downlink transmission termination position for an unlicensed spectrum through the GC-PDCCH in a third time slot that is different from than both the previous time slot and the time slot,
wherein the downlink transmission termination position either is indicated in the GC-PDCCH directly, or is determined according to slot format information included in the GC-PDCCH, and
wherein the processing circuit receives the data in the previous time slot of the time slot where the GC-PDCCH is located according to a default time slot format.
11. The electronic device according to claim 10 , wherein, based on the control information, the processing circuit determines at least one of a modulation and coding scheme (MCS) level of the data or time slot format related information (SFI) of the data.
12. The electronic device according to claim 10 , wherein the processing circuit:
stores data received in the previous time slot; and
demodulates the data in the previous time slot according to the control information.
13. The electronic device according to claim 10 , wherein the processing circuit receives, through the GC-PDCCH, time slot format related information (SFI) of the third slot where the downlink transmission termination position is located.
14. The electronic device according to claim 10 , wherein the processing circuit receives the control information related to the data in the previous time slot through the GC-PDCCH in response to a notification received from a network side device.
15. The electronic device according to claim 14 , wherein the processing circuit receives the notification from the network side device through a licensed spectrum.
16. The electronic device according to claim 10 , wherein the processing circuit receives a reconfigured transmission period of the GC-PDCCH from a network side device.
17. The electronic device according to claim 16 , wherein the processing circuit receives the reconfigured transmission period of the GC-PDCCH from the network side device through a licensed spectrum.
