Estimation of Number of Simultaneously Supported Interactive VoIP and Video Sessions in LTE-Advanced

Marko Porjazoski; Borislav Popovski

LTE-Advanced has engaged several techniques in order to enhance system performance enhancements compared to LTE. In this paper we evaluate LTE-Advanced capacity in the means of a number of simultaneously supported interactive VoIP and video sessions. Some new features that enable the capacity enhancements that are provided in LTE-Advanced like spatial multiplexing and Carrier Aggregation are overviewed. In order to calculate the number of supported users, we determine the number of resource elements available for user data transmission in downlink and uplink, taking in account all the resource elements used for redundant information. The maximal number of simultaneously supported interactive VoIP and video sessions is calculated assuming 64-QAM modulation with ¾ code rate for all transmissions. Finally the number of parallel VoIP and video sessions is calculated and compared for different LTE-A scenarios.
