Abstract:
1. A method of dynamically configuring a hybrid automatic repeat request (H-ARQ) memory in a receiving node for a plurality of H-ARQ processes, the method comprising: the receiving node reserving an H-ARQ memory for the plurality of H-ARQ processes; the receiving node signaling at least one of an H-ARQ memory sharing capability or a H-ARQ memory capacity to a transmitting node; and the receiving node receiving a memory configuration indication from the transmitting node based on the H-ARQ memory sharing capability and H-ARQ memory capacity for dynamically configuring the H-ARQ memory for at least each new H-ARQ transmission; the receiving node, transmitting a false ACK to the transmitting node when there is insufficient H-ARQ memory to prevent the transmitting node from sending a H-ARQ retransmission; the receiving node utilizing an automatic repeat request (ARQ) scheme to recover a transmission lost due to the false ACK transmission; and the receiving node is unable to inform the transmitting mode that there is insufficient H-ARQ memory.
