Device and method for processing HARQ data selectively using internal and external memories
First Claim
1. A device for receiving and processing Hybrid Automatic Repeat reQuest (HARQ) burst data, the device comprising:
- a HARQ processor comprising;
a combiner configured to receive a first HARQ burst;
an internal memory positioned within the HARQ processor; and
a memory selector configured to compare a size of the first HARQ burst with a predetermined threshold to generate a first comparison result, to select the internal memory as a first selected memory when the size of the first HARQ burst does not exceed the threshold, to select an external memory positioned outside the HARQ processor as the first selected memory when the size of the first HARQ burst exceeds the threshold, and to store the first HARQ burst in the first selected memory,wherein at least one among a size of the internal memory and the threshold is determined based on a characteristic of a service type that has been predetermined.

Abstract
A device and method for selectively using an internal memory and an external memory when processing Hybrid Automatic Repeat reQuest (HARQ) data are provided. The device includes a combiner configured to receive a first HARQ burst; an internal memory positioned within the device; and a memory selector configured to compare a size of the first HARQ burst with a predetermined threshold, to select one of the internal memory and an external memory positioned outside the device according to a comparison result, and to store the first HARQ burst in a selected memory. At least one among a size of the internal memory and the threshold is determined based on a characteristic of a first service type that has been predetermined.

7. A method of receiving and processing Hybrid Automatic Repeat reQuest (HARQ) burst data in a communication device, which comprises a HARQ processor and an external memory, the method comprising:
-
receiving, by the HARQ processor, a first HARQ burst; comparing, by the HARQ processor, a size of the first HARQ burst with a predetermined threshold to generate a first comparison result; selecting, by the HARQ processor, an internal memory positioned within the HARQ processor as a first selected memory, when the size of the first HARQ burst does not exceed the threshold; selecting, by the HARQ processor, the external memory positioned outside the HARQ processor as the first selected memory, when the size of the first HARQ burst exceeds the threshold; and
storing, by the HARQ processor, the first HARQ burst in the first selected memory,wherein at least one among a size of the internal memory and the threshold is determined based on a characteristic of a service type that has been predetermined. - View Dependent Claims (8, 9, 10, 11)

12. A device for receiving and processing Hybrid Automatic Repeat reQuest (HARQ) burst data, the device comprising:
a HARQ processor comprising; a combiner configured to receive a first HARQ burst; an internal memory positioned within the HARQ processor; and a memory selector configured to select the internal memory when a service type of the first HARQ burst is a first service type and the internal memory has available space, to select an external memory positioned outside the HARQ processor when the service type is a second service type, different from the first service type, or when the internal memory has no available space, and to store the first HARQ burst in a selected memory. - View Dependent Claims (13, 14)

15. A wireless communication device comprising:
-
a demodulator configured to demodulate a received signal and generate a demodulated signal; a log likelihood ratio (LLR) demapper configured to remap the demodulated signal to an LLR signal of N bits, where N is a real number of at least 1; a Hybrid Automatic Repeat reQuest (HARQ) processor configured to receive the LLR signal, to determine whether the LLR signal is a new signal or a retransmitted signal, and to generate a composite signal by combining the LLR signal with a related signal that has been received and previously stored in a first memory when the LLR signal is the retransmitted signal; and a decoder configured to decode the composite signal of the HARQ processor, wherein the HARQ processor is further configured to select the first memory when a service type of the LLR signal is a first service type and when the first memory has available space, and the HARQ processor selects a second memory when the service type is a second service type, different from the first service type, or when the first memory has no available space. - View Dependent Claims (16, 17, 18)
