摘要： The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

摘要： Embodiments are directed to transmitting L1 pre-signaling information with predetermined modulation and code rate such that L1 pre-signaling information can be received without preliminary knowledge on the network. L1 pre-signaling information makes it possible to receive the L1 signaling information, data link layer information, and notification data that may have configurable code rates and modulation. Therefore, L1 pre-signaling information can be thought of as signaling metadata (i.e., information about other signaling information). L1 signaling is divided into pre-signaling and signaling parts. The pre-signaling part includes parameters used for receiving the L1 signaling information. L1 pre-signaling signaling enables the receiver to receive the signaling itself (L1 signaling and data link layer information) by informing the receiver about the type of modulation, coding, and the like, used to transmit the L1 signaling, data link layer, and notification information.
摘要翻译：实施例旨在以预定的调制和码率传输L1预信令信息，使得可以在没有网络的初步知识的情况下接收L1预信令信息。 L1预信令信息使得可以接收可能具有可配置码率和调制的L1信令信息，数据链路层信息和通知数据。因此，L1预信令信息可以被认为是信令元数据（即关于其他信令信息的信息）。 L1信令分为前置信令和信令部分。预信令部分包括用于接收L1信令信息的参数。通过向接收方通知用于发送L1信令，数据链路层和调制信号的调制类型，编码等，L1预信令信令使得接收机能够接收信令本身（L1信令和数据链路层信息）通知信息。

摘要： Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. In another aspect of the invention, at least two pilot symbols may be defined and used at the beginning of each frame. The at least two pilot symbols P1 and P2 may enable fast channel search and service discovery within the frame. Signaling may be realized as a combination of L1 and L2 signaling.
