In the third generation wireless system UMTS, Radio Resource Management (RRM) functions should encompass scheduling algorithms. In particular, scheduling mechanisms play a key role in resource allocation for UMTS shared channels. These shared channels are mostly used in UMTS to support services such as web browsing and e-mail that work with the transport protocol TCP. So, performance achieved by TCP users in shared channels is closely related to RRM scheduling. In this paper the user studies the cross-layer interaction between TCP and two main sets of RRM scheduling strategies: rate-oriented and delay-oriented. Both strategies can be considered as the basic pillars behind more complex scheduling algorithms.
