Automatic retransmission request
First Claim
1. A method for communicating in a radiocommunication system comprising the step of:
- sending, from a base station, within the same downlink slot, a polling request and an access response mode indicator both carried as fields within an ARQ Mode BEGIN or an ARQ Mode CONTINUE layer 2 frame, along with shared channel feedback bits carried separately from the layer 2 frame, wherein said shared channel feedback bits are used to indicate that a next uplink slot associated with said downlink slot is reserved for mobile station transmission of requested status information.

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.
