Method and apparatus for transmitting and receiving downlink pre-emption indication data in next generation wireless network
Provided is a method for transmitting and receiving downlink pre-emption indication data in a next generation/5G wireless access network. The method for a terminal for receiving downlink pre-emption indication data may include: receiving monitoring configuration data for downlink pre-emption indication data from a base station; and, on the basis of the monitoring configuration data, monitoring the downlink pre-emption indication data, wherein the monitoring configuration data comprises data for whether to monitor the downlink pre-emption indication data.
1. A method of a user equipment (UE) for receiving downlink (DL) preemption indication information, the method comprising:
receiving monitoring configuration information on the DL preemption indication information from a base station; and
monitoring the DL preemption indication information based on the monitoring configuration information,
wherein the monitoring configuration information includes information on whether to monitor the DL preemption indication information, and
wherein the DL preemption indication information is indicated through group-common DL control information (DCI), and the group-common DCI is received through a resource after the preempted resource indicated by the DL preemption indication information.
2. The method according to claim 1 , wherein the monitoring configuration information is indicated through UE-specific radio resource control (RRC) signaling.
3. The method according to claim 1 , wherein the monitoring configuration information includes threshold time-domain scheduling interval information for determining whether the monitor the DL preemption indication information.
4. A method of a base station for transmitting downlink (DL) preemption indication information, the method comprising:
configuring monitoring configuration information on the DL preemption indication information;
transmitting the monitoring configuration information to a user equipment (UE); and
when DL is preempted, transmitting the DL preemption indication information to the user equipment,
wherein the monitoring configuration information includes information on whether to monitor the DL preemption indication information and
wherein the DL preemption indication information is indicated through group-common DL control information (DCI), and the group-common DCI is received through a resource after the preempted resource indicated by the DL preemption indication information.
5. The method according to claim 4 , wherein the monitoring configuration information is transmitted to the user equipment through UE-specific radio resource control (RRC) signaling.
6. The method according to claim 4 , wherein the monitoring configuration information includes threshold time-domain scheduling interval information for determining whether to monitor the DL preemption indication information.
7. A user equipment (UE) receiving downlink (DL) preemption indication information, the user equipment comprising:
a receiver receiving monitoring configuration information on the DL preemption indication information from a base station; and
a controller monitoring the DL preemption indication information based on the monitoring configuration information,
wherein the monitoring configuration information includes information on whether to monitor the DL preemption indication information, and
wherein the DL preemption indication information is indicated through group-common DL control information (DCI), and the group-common DCI is received through a resource after the preempted resource indicated by the DL preemption indication information.
8. The user equipment according to claim 7 , wherein the monitoring configuration information is indicated through UE-specific radio resource control (RRC) signaling.
9. The user equipment according to claim 7 , wherein the monitoring configuration information includes threshold time-domain scheduling interval information for determining whether to monitor the DL preemption indication information.
