Packet channel feedback
First Claim
1. A method for transmitting packet data information over a packet data channel in a communication system, comprising the steps of:
- providing a packet data channel over which a plurality of terminals can transmit said packet data information in an interleaved manner, said packet data information being addressed so that packets transmitted by different terminals can be routed to different destinations;
granting access of the packet data channel to a first communication device based on packet channel feedback information broadcast by said system, such that the first communication device transmits first packet data information on the packet data channel;
broadcasting, from said system, said packet channel feedback information associated with an interrupt status of said packet data channel;
interrupting the first packet data transmission from the first communication device for an interruption period in response to said broadcast interrupt status; and
granting access of the packet data channel to a second communication device, wherein the second transmits second packet data information during the interruption period.

Abstract
A method is disclosed for improving the efficiency of the packet data channel by providing means for interrupting tranmsissions so as to allow a communication system to send a short message to a different mobile station. The packet channel feedback information includes several flags: Busy-Reserved/Idle (BRI); Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.

3. A method for temporarily interrupting transmission of data packets by a first communication device on a packet data channel in a communication system, comprising the steps of:
-
inserting control information into a control message generated by the system, said control information including packet channel feedback information associated with (1) granting access to said packet data channel and (2) interruption of transmission on said packet data channel; transmitting the control message to the first communication device; and interrupting packet data transmission of the first communication device in response to receiving the control information for an interruption period as selectively indicated by said interruption information included in said packet channel feedback information. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
