Method and device for allocating persistent resource in mobile communication system

摘要

A method and a device for allocating a persistent resource in a mobile communication system are provided. In a broadband mobile communication system such as an IEEE 802.16m system, when allocating a persistent resource, because the terminal may transmit a Hybrid Automatic Repeat reQuest (HARQ) sub packet in a continuous frame without receiving the HARQ feedback from the base station, uplink coverage may be extended. When persistent resource allocation is used in uplink, the base station may transmit an HARQ sub packet without receiving the HARQ feedback during the persistent resource allocation period to improve uplink coverage of an allocated persistent resource.

1. A method for allocating a persistent resource in a mobile communication system, the method comprising:
determining an error rate of a received packet; transmitting a uplink persistent resource allocation Information Element (IE) including an N_frame which continuously transmits during a persistent allocation period when the error rate of the received packet exceeds a preset reference value; and receiving the same packets of the N_frame during the persistent resource allocation period and not transmitting Hybrid Automatic Repeat reQuest (HARQ) Feedback Allocation (HFA) feedback according to the reception of the packet.
