CPC Class H04W

An apparatus is provided for estimating one or more quality of experience (QoE) parameters associated with a specific terminal. The apparatus includes a traffic processor configured to acquire a plurality of transactions for providing multimedia content to a specific terminal. At least one of such transactions is a secured transaction. The apparatus further includes a QoE parameter estimator configured to detect a quality level variation event based on the transactions and the sizes of the transactions, and to estimate one or more QoE parameters based on the detection of the quality level variation event.

Embodiments herein achieve systems and methods for managing communication in a Mission Critical data (MCData) communication system. The proposed method and system provides file distribution and data streaming in the MCData communication system. The proposed method and system provides a functional model and mechanisms to support mission critical data services. The functional model to support file distribution and data streaming, and associated procedures including one-to-one, one-to-many, and group data communications. Further, the proposed method and system provides mechanisms for optimizing radio resource utilization and backhaul link utilization in the MCData communication system. The proposed method and system provides radio resource utilization of the PC5 interface for the MC service, when multiple group members are under a relay node. Further, the proposed method and system can be used to reduce number of unicast transmissions between the MCData server and the MCData UEs by local routing at the relay node.

A method and apparatus for establishing peer-to-peer communication in a wireless network is described. A wireless transmit/receive unit (WTRU) may receive configuration information comprising periodic resources comprising time and subcarrier resources from a base station of a wireless network. The time and subcarrier resources may be used in discovery of other WTRUs. The WTRU is further configured to transmit an identification in the allocated resources and to transmit a synchronization signal to a peer WTRU for timing synchronization of the peer WTRU.
