摘要： A base station (110) in a wireless communications network (100) counts mobile stations (114) receiving broadcast content via multi-user channel. The base station broadcasts (608) a repeating message identifying at least one broadcast content stream and, for each stream, a REGISTER (R) or DO NOT REGISTER (DNR) indicator. Mobile stations periodically re-examine (722) contents of this message. When the indicator is R for a broadcast content stream, mobile stations whose users have elected to receive it send (714) the base station a registration message for that stream. When the number of registered mobile stations reaches (612) a prescribed number, the base station changes (614) the indicator to DNR. When the indicator is DNR for a broadcast content stream, mobile stations refrain (712/716) from sending any registration message for that broadcast content stream. The base station may institute a recount (618) by resetting the indicator to R.

摘要： Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

摘要： Feedback from user stations to the base station for a multicast/broadcast transmission is performed by decoding multicast/broadcast data received from a transmitter on a downlink resource, forming a feedback message corresponding to the reception of the multicast/broadcast data, and queuing the feedback message for transmission to the transmitter on an uplink resource. The uplink resource used corresponds to the downlink resource used for the multicast/broadcast transmission. For unicast transmissions the uplink resource is dedicated to an uplink transmission corresponding to a downlink transmission on the downlink resource.

摘要： Methods and apparatus are described for broadcasting content. Encoding the content to be multicast/broadcast into multiple streams, wherein at least one stream provides a base portion of the content, and additional streams provide enhancements to the content. A wireless communication device receives the broadcast and decodes streams in accordance with the reception capabilities of the wireless device. The configuration of the wireless device can be determined based on the wireless device's capability to decode multiple streams. In addition, the configuration of the wireless device can be determined based on a subscriber level of the wireless device.

摘要： An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.
