METHOD AND SYSTEM FOR FACILITATING TRANSMISSION OF TTI BUNDLES VIA A LTE DOWNLINK CHANNEL

摘要

A method and system for facilitating communication between an Evolved Node B (eNB) and a user equipment (UE) in a Long Term Evolution (LTE) network. In particular the technology addresses downlink transmission via potentially large TTI bundles. The eNB transmits a downlink grant message to the UE, indicating a pending TTI bundle for downlink transmission. The UE transmits an acknowledgement message to the eNB if the DL grant message is successfully received and decoded. The eNB aborts transmission of the TTI bundle if it fails to timely receive the acknowledgement and may reassign the network resources scheduled for use in the transmission. In some embodiments, the eNB may introduce a delay between the downlink grant message and the TTI bundle.

1. A method for facilitating communication between an Evolved Node B (eNB) and a user equipment (UE) in a Long Term Evolution (LTE) system, the method comprising:
a. transmitting a downlink (DL) grant message from the eNB to the UE, the DL grant message indicative of a pending TTI bundle for transmission from the eNB to the UE; b. transmitting an acknowledgement message from the UE to the eNB when the DL grant message is successfully received and decoded by the UE; and c. aborting transmission of the TTI bundle from the eNB to the UE when successful receipt by the eNB of the acknowledgement message fails to occur within an expected time interval.
