Methods and systems for power savings using a message indication header

摘要

Techniques for signaling a mobile communications device in a special operating state that data bursts contain messages relevant to the special operating state. The signaling may be implemented using one or more bits in a frame control header (FCH). As a result, the mobile communication device may be decode the FCH first and decode data bursts only if there is an indication the data bursts contain a relevant message. Power savings may be achieved at the mobile communications device by avoiding decoding data bursts with no relevant messages.

1. A method for signaling a wireless communication device in a special operating state that a frame of data contains a message relevant to the special operating state, comprising:
generating a frame control header for a frame with a message indication field having one or more bits for indicating a message relevant to the special operating state of the wireless communications device is contained in corresponding data bursts of the frame, wherein the message indication field comprises a set of message indications bits which indicate a presence of a power save related message, wherein a first configuration of the set of message indication bits indicates the presence of a channel message identifying physical characteristics of the channel, wherein a second configuration of the set of message indication bits indicates the presence of a traffic message signifying the arrival of traffic destined for the device, and wherein a third configuration of the set of message indication bits indicates the presence of a update message signifying a need for the device to provide a location update to a base station; and transmitting the frame control header.
