Automatic retransmission request
First Claim
1. A method for determining the status of Automatic Transmission Request (ARQ) Mode BEGIN and CONTINUE frames sent to a remote station, comprising the steps of:
- receiving, at the remote station, an Automatic Retransmission Request (ARQ) Mode BEGIN frame with a remote station identity associated with said remote station and storing partial echo and transaction identifier values contained in the Automatic Retransmission Request Mode BEGIN frame; and
receiving, at said remote station, at least one subsequent Automatic Retransmission Request Mode CONTINUE frame having partial echo and transaction identifier values that match the stored partial echo and transaction identifier values.

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.

4. A method for identifying to which mobile station a plurality of linked frames are being sent to in a cellular communication system, comprising the steps of:
-
receiving a begin frame at a mobile station; comparing said mobile station'"'"'s mobile station identification with a mobile station identification in said begin frame; storing partial echo and transaction identifier values contained in said begin frame with a matching mobile station identification; receiving at least one continuation frame, wherein said continuation frame contains partial echo and transaction identifier values that match the stored partial echo and transaction identifier values.

5. A method for transmitting a message in a radiocommunication system, comprising the steps of:
-
transmitting an Automatic Retransmission Request (ARQ) Mode BEGIN frame from a base station to a mobile station; polling said mobile station; transmitting an Automatic Retransmission Request status message to said base station in response to said polling; retransmitting said Automatic Retransmission Request Mode BEGIN frame when Automatic Retransmission Request status message is not received at said base station or if the Automatic Retransission Request status message is incorrect; and transmitting at least one Automatic Retransmission Request (ARQ) Mode CONTINUE frame when said message is too large to be transmitted by the Automatic Retransmission Request Mode BEGIN frame and when a correct Automatic Retransmission Request status message is received by the base station. - View Dependent Claims (6, 7, 8)
