Memory management method and apparatus for receiving multi channel hybrid automatic repeat request (HARQ) packet

摘要

A memory management method for receiving a multi channel hybrid automatic repeat request (HARQ) packet may enable smooth communication and reduce costs by maintaining a small memory size of a receiver in a communication system using a HARQ including a plurality of channels.

主权项

1. A memory management method, the method comprising:
generating state information for indicating memory state of a receiver; and transmitting HARQ(Hybrid Automatic Retransmit Request) feedback packet including the state information to a transmitter, wherein the state information includes (i) first state in which space to store a new erroneous packet in a memory of the receiver is enough, (ii) second state in which space to store a new erroneous packet in the memory of the receiver is not enough, (iii) third state in which an erroneous packet corresponding to the HARQ feedback packet is not stored in a memory of the receiver, and (iv) fourth state in which an erroneous packet corresponding to the HARQ feedback packet is needed to retransmit from an initial transmission.
