    摘要: A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network.

    摘要: A method and apparatus for improving handover in an IEEE 802.21 compliant communication network. A query is transmitted from a wireless transmit/receive unit (WTRU) to a media independent handover (MIH) server (MIHS). The WTRU includes a target point of attachment (PoA) and/or a preferred mobile inter protocol (MIP) method. The WTRU receives a response from the MIHS indicating the MIP method supported by the target PoA. Based on the received response, the WTRU may make an informed decision regarding handover.

    摘要: A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of user terminals. Each user terminal includes a receiver and a controller that receives a first orthogonal frequency division multiplexing (OFDM) signal on a first carrier frequency that has assignment information indicating a second carrier frequency to transmit uplink data and beam forming information. In response to the assignment information, a transmitter of the user terminal transmits a second OFDM signal on the second carrier frequency using a beam indicated in the beam forming information.

    摘要: A wireless transmit/receive unit (WTRU) may include a media application that receives data from a media server via a link on a downlink (DL) -only radio access network. The link on the DL-only radio access network may be handed over to a second DL-only radio access network. A mobility management server, such as a Media Independent Handover (MIH) server, may communicate with the WTRU via a second radio access network that is a bidirectional radio access network to facilitate the handover. MIH messages may include fields that relate to DL-only radio access technologies may be used to facilitate handover of a DL-only link. Further, MIH broadcast or multicast messages may be used to facilitate the handover of a DL-only link.
