Method for transmitting and receiving downlink pre-emption indication information using bitmap in new radio networks and apparatus thereof
Provided is a method for transmitting and receiving downlink pre-emption indication information using a bitmap in a next-generation/5G radio access network. The method may include: receiving monitoring configuration information for downlink pre-emption indication information from a base station; monitoring downlink pre-emption indication information based on the monitoring configuration information; and receiving the downlink pre-emption indication information from the base station, wherein the downlink pre-emption indication information includes a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among reference downlink resources.
1. A method for receiving downlink pre-emption indication information by a user equipment, the method comprising:
receiving monitoring configuration information for downlink pre-emption indication information from a base station;
monitoring downlink pre-emption indication information based on the monitoring configuration information; and
receiving the downlink pre-emption indication information from the base station,
wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among reference downlink resources,
wherein respective bits of the bitmap are mapped with different resources to distinguish between resources and to indicate one of M different time-section resources and indicates one of N different frequency-section resources where M and N are a natural number equal to or greater than 1,
wherein the bitmap comprises 14 bits, and
wherein M and N have values such that M=14 and N=1 or M=7 and N=2.
2. The method of claim 1 , wherein the downlink pre-emption indication information is indicated through group-common downlink control indication (DCI).
3. The method of claim 1 , wherein the information for setting a unit of time-section resources and a unit of frequency-section resources is received from the base station through higher layer signaling.
4. A method for transmitting downlink pre-emption indication information by a base station, the method comprising:
configuring monitoring configuration information for downlink pre-emption indication information;
transmitting the monitoring configuration information to a user equipment; and
transmitting the downlink pre-emption indication information to the user equipment when downlink pre-emption occurs,
wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources a frequency-section resources in which pre-emption has occurred, among reference downlink resources,
wherein respective bits of the bitmap are mapped with different resources to distinguish between resources and to indicate one of M different time-section resources and indicate one of N different frequency-section resources, where M and N are a natural number equal to or greater than 1,
wherein the bitmap comprises 14 bits, and
wherein M and N have values such that M=14 and N=1 or M=7 and N=2.
5. The method of claim 4 , wherein the downlink pre-emption indication information is transmitted to the user equipment through group-common downlink control indication (DCI).
6. The method of claim 4 , wherein the information for setting a unit of time-section resources and a unit of frequency-section resources is transmitted to the user equipment through higher layer signaling.
7. A user equipment for receiving downlink pre-emption indication information, the user equipment comprising:
a receiver configured to receive monitoring configuration information for downlink pre-emption indication information from a base station and configured to receive the downlink pre-emption indication information from the base station; and
a controller configured to monitor the downlink pre-emption indication information based on the monitoring configuration information,
wherein the downlink pre-emption indication information comprises a bitmap indicating information on at least one of time-section resources and frequency-section resources in which pre-emption has occurred, among reference downlink resources,
wherein respective bits of the bitmap are mapped with different resources to distinguish between resources and to indicate one of M different time-section resources and indicate one of N different frequency-section resources, where M and N are a natural number equal to or greater than 1,
wherein the bitmap comprises 14 bits, and
wherein M and N have values such that M=14 and N=1 or M=7 and N=2.
8. The user equipment of claim 7 , wherein the downlink pre-emption indication information is indicated through group-common downlink control indication (DCI).
9. The user equipment of claim 7 , wherein the information for setting a unit of time-section resources and a unit of frequency-section resources is received from the base station through higher layer signaling.
