The invention discloses a resource multiplexing method and system based on URLLC service delay tolerance. The method comprises the following steps: a wireless access point sends SIB1 information to wireless communication equipment; when the wireless communication equipment generates the URLLC service requirement, scheduling information is generated, and the scheduling information is sent to the wireless access point; the wireless access point judges whether the URLLC service can tolerate the longest waiting delay under the slice frame structure; if not, the resource reuse scheme is configured to be based on an unlicensed mode; if yes, URLLC service type information is obtained, and whether the URLLC service of the wireless communication equipment is periodic or not is determined; if not, the resource reuse scheme is configured to be in an improved GB mode; if yes, the resource reuse scheme is configured to be in a GF mode. According to the invention, on the premise that the low-delay technical requirement of URLLC service is met, the occurrence probability that time-frequency domain resources of eMBB UE for transmitting data are preempted, punctured and punctured is reduced, and the throughput and the signal-to-noise ratio of the eMBB UE are further improved.
Description
technical field [0001] The present invention relates to the field of 5G communication technology, in particular to a resource multiplexing method based on URLLC service delay tolerance and a resource multiplexing system based on URLLC service delay tolerance. Background technique [0002] In related technologies, in order to maximize resource utilization and spectrum efficiency, the static resource reservation and multiplexing scheme of GB mode is often used; however, in the dynamic preemptive resource multiplexing scheme based on authorized GB; URLLC UE is allowed to , through gNB authorization to preempt, punch, and puncture the time-frequency domain resources originally used by eMBB UEs for data transmission, so that URLLC services can be immediately scheduled to meet the technical requirements of end-to-end low latency. However, due to the occurrence of preemption, puncturing, and puncture, demodulation failure and additional retransmission between the eMBB UE and gGB at...
