    Abstract: A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

    Abstract: Each of a plurality of packets in a particular flow is classified into one of a plurality of quality of service (QoS) classes based on information about each packet. Each packet is then adaptively processed based on the QoS class for each packet. The classification may be performed based on media information included in a session description protocol (SDP) messaging. The classification may also be performed based on a real-time transmit protocol (RTP) payload, an RTP header, a transmission control protocol (TCP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header. The packets may be transmitted using multiple system architecture evolution (SAE) radio bearers each of which is used to deliver differentiated QoS requirements. The packets may be mapped to eigen-modes based on the QoS class of each packet such that a packet requiring a higher level of QoS is mapped to a stronger eigen-mode. Packets may be segmented into a plurality of segments where each segment is classified into one of the QoS classes based on information about each segment.
