RADIO MAC SCHEDULING BASED ON FRONT-HAUL TRANSPORT CAPACITY CONSTRAINTS

摘要

In certain embodiments, a 5G RAN network has a distributed unit (DU) connected to at least one remote unit (RU) via a transport network (TN) that handles both mobile front-haul (MFH) traffic between the DU and the RUs as well as non-MFH traffic with other end users. A radio scheduler in the DU is configured to perform medium access control (MAC) scheduling for the mobile user traffic, while a TN scheduler in the transport network is configured perform TN scheduling for both the MFH and non-MFH traffic. The TN scheduler is configured to transmit information (e.g., MFH data-rate limits) to the radio scheduler that the radio scheduler uses to perform its subsequent MAC scheduling.
