METHOD FOR TRANSMITTING RETRANSMISSION REQUEST INFORMATION FOR AN ERROR PACKET IN A MULTIMEDIA BROADCAST/MULTICAST SERVICE, AND METHOD FOR RETRANSMITTING A PACKET IN RESPONSE TO THE RETRANSMISSION REQUEST

摘要

Disclosed is a method in which a terminal transmits retransmission request information for an error packet of a multimedia broadcast/multicast service (MBMS), and a base station retransmits a packet in the multimedia broadcast/multicast service. The method in which the terminal transmits retransmission request information for an error packet comprises: a step of receiving an MBMS packet from the base station; a step of checking whether or not an error exists in the received MBMS packet; and a step of transmitting retransmission request information for the error packet using at least one of PUSCH, PUCCH and a random access preamble for a random access process if an error exists in the received MBMS packet. The present invention achieves improved service satisfaction among terminals located on an intercell boundary, an MBSFN boundary, and regions with a poor wireless environment.
