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.
摘要翻译：无线通信网络（100）中的基站（110）对通过多用户信道接收广播内容的移动台（114）进行计数。基站广播（608）识别至少一个广播内容流的重复消息，并且针对每个流，广播（608）REGISTER或者不注册（DNR）指示符。移动台定期重新检查（722）该消息的内容。当指示符为广播内容流的R时，其用户已经选择接收的移动台向基站发送（714）该流的注册消息。当登记的移动站的数量达到（612）规定数量时，基站将指示符改变（614）为DNR。当指示符是用于广播内容流的DNR时，移动台拒绝（712/716）发送用于该广播内容流的任何注册消息。基站可以通过将指示符重置为R来进行重新计数（618）。

摘要： Techniques for transmitting data and training sequence efficiently using new slot and block formats are described. A transmitter processes (e.g., encodes, interleaves, and partitions) a data block to obtain multiple output blocks. For each output block, the transmitter generates multiple bursts having a training sequence that is shared by these bursts. The transmitter sends the multiple bursts for each output block in multiple time slots, e.g., consecutive time slots in one frame. The multiple bursts for each output block may (1) include one or more short training sequences, (2) omit guard periods between adjacent bursts, (3) include a first tail bit field at the start of the first burst and a second tail bit field at the end of the last burst, (4) include at least one stealing flag field, or (5) have any combination of the above.

摘要： Techniques for reliable transmission of higher priority data within a frame are disclosed. In one aspect, an inner code is applied to one or more partial segments of a transmitted data frame in addition to any outer code applied to the entire frame. In another aspect, inner coded segments of a received frame are decoded when decoding of the outer code indicates one or more errors within the frame. The inner coded segment is retained when the inner decoding decodes without error. Various other aspects are also disclosed. These aspects have the benefits of reducing the number of retransmissions of higher priority data, as well as reducing delay for time-sensitive segments of the frame. The result is more efficient use of bandwidth, more responsiveness to higher priority segments, such as signaling traffic, and capacity, power, and other efficiencies associated therewith.
摘要翻译：公开了在帧内可靠传输较高优先级数据的技术。在一个方面，除了应用于整个帧的任何外部代码之外，还将内部代码应用于所发送的数据帧的一个或多个部分段。在另一方面，当外部码的解码指示帧内的一个或多个错误时，解码接收帧的内部编码段。当内部解码无错误地解码时，内部编码段被保留。还公开了各种其它方面。这些方面具有减少更高优先级数据的重传次数以及减少帧的时间敏感部分的延迟的好处。结果是更有效地使用带宽，对较高优先级段的响应更高，例如信令流量，以及与其相关联的容量，功率和其他效率。

摘要： Various method and apparatus provides for matching revision levels used by a mobile station (102-104) and a base station (101, 160) for establishing a communication link. The mobile station repeats, for a number of times, the transmission of a request for establishing a communication link between the mobile station and the base station. The mobile station detects failure of establishing the communication link with the first revision level based on repeating the request for the number of times. The mobile station changes the first revision level to the second revision level at the mobile station for establishing the communication link.

摘要： Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

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.
摘要翻译：提供了传输技术，其提高服务连续性并减少当用户设备（UE）从一个小区移动到另一个小区时发生的转换可能导致的内容传递中断，或者当内容的传递从点到 -Point（PTP）连接到同一服务小区中的点对多点（PTM）连接，反之亦然。这样的传输技术能够跨小区边界和/或不同传输方案（例如点对多点（PTM）和点对点（PTP））之间的无缝传递内容。还提供了用于在这种转换期间调整不同流并用于从每个数据块恢复内容的机制，使得数据在转换期间不会丢失。此外，还提供了在接收终端的解码期间重新对准数据的机制。
