Abstract: An access network determines to transmit multicast messages on a downlink shared channel. The access network receives a multicast registration message and a traffic channel request from at least one access terminal. The access network assigns a traffic channel to the at least one access terminal, and transmits the multicast messages on the downlink shared channel. In another example, the access network can determine a channel type upon which the support a multicast session, can indicate the channel type selection to the at least one access terminal in an announce message and can then transmit the multicast messages for the multicast session on the selected channel type. The at least one access terminal receives the announce message, requests a traffic channel and receives a traffic channel assignment, registers to the multicast session and monitors the downlink shared channel for multicast messages.

Abstract: In an embodiment, an access terminal sends a multicast session registration request to an access network. The access network determines whether to assign a unicast traffic channel (e.g., media access control (MAC) identifier (ID)) to the access terminal, for the access terminal to provide feedback (e.g., channel quality indicators (CQIs) associated with the multicast session, based on a number of access terminals that have been assigned unicast traffic channels for the multicast session and/or for applications other than the multicast session. The access network configures a traffic channel assignment message to include an identifier for the multicast session, and to further include an assignment of the unicast traffic channel if the determining step determines to assign the unicast traffic channel to the access terminal. The access network sends the traffic channel assignment message to the access terminal including at least the multicast session identifier.

Abstract: Methods in a multiple-cell cellular network that implements iterative coordinated beamforming (I-CBF) algorithms with limited cooperation from adjacent nodes (base stations and/or mobile stations) may jointly determine transmit beamforming vectors and receive combining vectors to increase sum throughput. The transmit beamforming vectors and receive combining vectors can be determined based on a performance metric, such as by maximizing SINR (signal-to-interference-and-noise ratio) for each mobile station in the network, maximizing SLNR (signal-to-leakage-and-noise ratio) for each base station in the network, or minimizing SMSE (sum mean square error). The algorithms may be performed to update vectors synchronously. In other cases, the algorithms may be performed to update vectors asynchronously.

Abstract: Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message.

Abstract: An access network (AN) receives a call announcement message for transmission to an access terminal (AT). The AN initiates, in response to the received call announcement message, a physical-layer synchronization procedure for at least one channel between the AN and the AT, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state. The AN performs the initiation by sending a message to the AT. In response to the message, the AT monitors a downlink channel for receipt of the call announcement message. The AN then transmits the call announcement message on the downlink channel to the access terminal, and the AT receives the call announcement message due to the monitoring. The call announcement message is transmitted either (i) before the physical layer synchronization procedure completes or (ii) before a transmission of a reconfiguration complete message indicating completion of dedicated channel state transition.
