Method for transmitting and receiving downlink pre-emption indication information using bitmap in new radio networks and apparatus thereof

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.

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.
