MTC UE AND METHOD FOR COVERAGE ENHANCEMENT USING RADIO LINK CONTROL CONFIGURATION

摘要

An eNodeB (eNB) and user equipment (UE) are provided that detect whether the UE is in coverage enhancement mode and if so uses a modified version of the Radio Link Control (RLC) configuration in communications between the eNB and UE. Detection mechanisms may differ between the eNB and UE and may include direct signaling between the eNB and UE, the ability to receive control signaling only through particular modified signaling procedures, low power of certain received control signals or lack of response to certain control signals within various predetermined time periods. The modified RLC configuration permits a smaller amount of data than a standard RLC configuration to be transmitted by a transmitting device before a receiving device is able to be polled for information regarding reception by the receiving device of the transmitted data.
