    Abstract: A communications system in which information is transmitted in successive time slots grouped into a plurality of superframes which are, in turn, grouped into a plurality of hyperframes. A remote station is assigned to one of the time slots in each of the superframes for paging the remote station, each hyperframe including at least two superframes, and the information sent in the assigned time slot in one superframe in each hyperframe is repeated in the assigned time slot in the other superframe(s) in each hyperframe. Each superframe can include a plurality of time slots used for sending paging messages to remote stations, grouped into a plurality of successive paging frames, and the time slot to which the remote station is assigned is included once in every paging frame. Also, each superframe may include time slots comprising a logical channel for broadcast control information and time slots comprising a logical paging channel. Information sent in the assigned time slot may direct the remote station to read the broadcast control information, and the information may have been encoded according to an error correcting code and include a plurality of bits having polarities that are inverses of cyclic redundancy check bits produced by the encoding. Also, the broadcast control information may comprise special messages that are included in respective time slots comprising a logical special message channel, the time slots of the special message channel may be grouped in successive SMS frames, and the SMS frames may be synchronized to start with a start of a superframe.

    Abstract: A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.

    Abstract: Un nodo de red de acceso de radio (RAN), un dispositivo inalámbrico y diversos métodos se describen en el presente documento para el manejo de ancho de banda de búsqueda. En una modalidad, el nodo de RAN transmite un mensaje (por ejemplo, mensaje de búsqueda, mensaje de asignación) a los dispositivos inalámbricos, en donde el mensaje comprende al menos lo siguiente: (i) un campo de modo de página que incluye información que indica una o más clases de cobertura para la cual uno o más mensajes de búsqueda estaban disponibles para la transmisión durante un intervalo de tiempo pero no fueron transmitidos a una pluralidad de dispositivos inalámbricos; y (ii) un campo used_downlink_coverage_class que incluye información que indica una clase de cobertura asociada con el mensaje transmitido.
