EMBMS BANDWIDTH AUTO-FITTING

摘要

A node in a Long-Term Evolution (LTE) network allocates sub-frames to an Evolved Multimedia Broadcast Multicast Service (eMBMS) service. The node calculates a sub-frame usage for transmitting the eMBMS service to users based on a Modulation and Coding Scheme (MCS) of the eMBMS service and a data count of the eMBMS service in a time period. Based on the calculated sub-frame usage, a configuration that specifies sub-frame allocation for the eMBMS service is adjusted when the configuration does not match the calculated sub-frame usage of the eMBMs service. The node then allocates the sub-frames to the eMBMS service according to the configuration. The calculating, adjusting and allocating operations are repeated during transmission of the eMBMS service to the users.
