Method and apparatus for transmitting and receiving data multiple times in consecutive subframes
First Claim
Patent Images
1. A method for transmitting data by a transmitting device, the method comprising:
- applying, by the transmitting device, a redundancy version (RV) to the data;
scrambling, by the transmitting device, the data; and
transmitting, by the transmitting device, the data multiple times in N consecutive subframes, where N is a positive integer greater than 1,wherein the data is transmitted more than once over R consecutive subframes in the N consecutive subframes, and the RV applied to the data is same over the R consecutive subframes, where R is a predefined positive integer greater than 1,wherein the RV applied to the data is changed every R consecutive subframes in the N consecutive subframes, where N is greater than R, andwherein the data is scrambled with a same scrambling sequence over the R consecutive subframes for which the RV applied to the data stays the same.

Abstract
The present invention provides a method and apparatus for transmitting data and a method and apparatus for receiving data, wherein said methods transmit/receive a reference signal in sub-frames bundled for data transmission/reception using at least an identical precoding matrix, an identical reference signal sequence, an identical reference signal generating identifier, or an identical reference signal scrambling sequence.

3. A method for receiving data by a receiving device, the method comprising:
-
receiving, by the receiving device, the data multiple times in N consecutive subframes, where N is a positive integer greater than 1; and decoding, by the receiving device, the multiple times received data based on one or more redundancy versions (RVs) for the data and one or more scrambling sequences for the data, wherein the data is received more than once over R consecutive subframes in the N consecutive subframes, and the data is decoded using a same RV over the R consecutive subframes, where R is a predefined positive integer greater than 1, wherein the RV used for the data is changed every R consecutive subframes in the N consecutive subframes, where N is greater than R, and wherein the data is decoded using a same scrambling sequence over the R consecutive subframes for which the RV used for the data stays the same. - View Dependent Claims (4, 12, 13, 14)

5. A transmitting device for transmitting data, the transmitting device comprising:
-
a radio frequency (RF) unit; and a processor configured to; apply a redundancy version (RV) to the data; scramble the data; and control the RF unit to transmit the data multiple times in N consecutive subframes, where N is a positive integer greater than 1, wherein the data is transmitted more than once over R consecutive subframes in the N consecutive subframes, and the RV applied to the data is same over the R consecutive subframes, where R is a predefined positive integer greater than 1, and wherein the RV applied to the data is changed every R consecutive subframes in the N consecutive subframes, where N is greater than R, and wherein the processor is configured to scramble the data with a same scrambling sequence over the R consecutive subframes for which the RV applied to the data stays the same. - View Dependent Claims (6, 15, 16, 17)

7. A receiving device for receiving data, the receiving device comprising:
-
a radio frequency (RF) unit; and a processor configured to; control the RF unit to receive the data multiple times in N consecutive subframes, where N is a positive integer greater than 1, and decode the multiple times received data based on one or more redundancy versions (RVs) for the data and one or more scrambling sequences for the data, wherein the data is received more than once over R consecutive subframes in the N consecutive subframes, and the data is decoded using a same RV over the R consecutive subframes, where R is a predefined positive integer greater than 1, wherein the RV used for the data is changed every R consecutive subframes in the N consecutive subframes, where N is greater than R, and wherein the data is decoded using a same scrambling sequence over the R consecutive subframes for which the RV used for the data stays the same. - View Dependent Claims (8, 18, 19, 20)
