US 2017/0366303 A1 · TRANSMISSION CONTROL METHOD FOR HARQ IN MOBILE COMMUNICATION SYSTEM

Abstract

A transmission control method for HARQ is provided for improving HARQ performance in a mobile communication system. The transmission control method for Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system according to the present invention includes receiving an downlink resource assignment message; determining whether configured downlink assignment has been indicated to an HARQ entity since a previously received downlink assignment for a User Equipment's (UE's) Cell-Radio Network Temporary Identifier (C-RNTI) for the same HARQ process; maintaining, if the configured downlink assignment has not been indicated to the HARQ entity, the HARQ process; and processing, if the configured downlink assignment has been indicated to the HARQ entity, the downlink resource assignment message as a resource assignment message for initial transmission.

Claims8

Dependent claims

A method by a terminal, the method comprising:

receiving a transport block (TB) based on downlink control information;
determining, if a reset of a medium access control (MAC) entity is requested, whether the TB received after the reset of the MAC entity is for a cell-radio network temporary identifier (C-RNTI) of the terminal;
and
determining, if the received TB is for the C-RNTI, a new data indicator (NDI) of the downlink control information to have been toggled regardless of a value of the NDI.
