Patent number: 12389427Abstract: Methods for scheduling mixed type traffics via multiple Transmission/Reception Points (TRPs) are provided. In embodiments disclosed herein, a base station provides, and a wireless device receives, a scheduling information for scheduling the mixed type traffics with different Quality of Service (QoS) requirements via multiple TRPs. In a non-limiting example, the mixed type traffics include an enhanced Mobile Broadband (eMBB) service and an Ultra-Reliable and Low Latency Communication (URLLC) traffic service, and the scheduling information can be conveyed in a single Downlink Control Information (DCI) or a pair of DCIs. As such, it is possible to enable efficient scheduling of both eMBB traffic and URLLC traffics simultaneously. As a result, it is possible to satisfy a reliability requirement of the URLLC service without sacrificing spectral efficiency and/or throughput of the eMBB service.Type: GrantFiled: March 12, 2021Date of Patent: August 12, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ying Sun, Yutao Sui, Mattias Frenne, Mattias Andersson, Siva Muruganathan
