Title:
APPARATUS AND METHOD FOR SEMI-PERSISTENT SCHEDULING
Document Type and Number:
WIPO Patent Application WO/2020/204491
Kind Code:
A1
Abstract:
The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The disclosure provide a semi-persistent scheduling method, a base station device and a user equipment, wherein, the semi-persistent scheduling method comprises: transmitting a configuration information of semi-persistent scheduling parameters to a user equipment (UE), so that the UE performs a semi-persistent scheduling data transmission based on the configuration information; and performing the semi-persistent scheduling data transmission based on the configuration information of the semi-persistent scheduling parameters. By the method in the embodiments of the present application, the low-latency requirements of the URLLC(ultra-reliable low-latency communication) is satisfied, so that existing semi-persistent scheduling transmission mechanism can support higher low-latency requirements, and introduce multiple semi-persistent scheduling configuration at the same time and assign different time-frequency resources for each semi-persistent scheduling configuration, thus finally multiple types of services can be simultaneously supported.
