Definitions
- the 1-bit control signals for different transmitting sides are multiplexed in a plurality of the time-frequency domains by the code division multiple access, respectively.
- a plurality of the 1- bit control signals for the specific transmitting side are multiplexed by different orthogonal or pseudo-orthogonal codes .
- FIG. 2 is a diagram for explaining a method of transmitting ACK/NACK signals by carrying out multiplexing side by side with CDMA and FDMA according to one embodiment of the present invention
- FIG. 4 is a diagram for explaining a method of transmitting ACK/NACK signals by carrying out multiplexing side by side with CDMA and FDMA according to one embodiment of the present invention, in which a plurality of ACK/NACK signals transmitted by a specific transmitting side among a plurality of ACK/NACK signals are transmitted through a plurality of frequency domains;
- FJG. 9 is a diagram to explain a principle that power allocation flexibility is increased in case of transmitting ACK/NACK signals by the embodiment shown in FIG. 8.
- FIG. 3 is a diagram for explaining a method of transmitting ACK/NACK signals by carrying out multiplexing side by side with CDMA, TDMA and FDMA according to one embodiment of the present invention.
- one preferred embodiment of the present invention proposes that more ACK/NACK signals can be simultaneously transmitted in a manner of specifying orthogonal codes in accordance with the size of the entire domains instead of specifying an orthogonal code in accordance with in the size of each the time-frequency domain and then transmitting a plurality of ACK/NACK signals correspondingly.
- FIG. 5 shows an example that a time-frequency diversity gain is obtained in a manner that ACK/NACK signals for a specific UE are transmitted across two different time-frequency domains.
- the method of transmitting ACK/NACK signals repeatedly in a plurality of time-frequency domains to secure the transmission diversity gain can be diversified in accordance with a number of available OFDM symbol zones.
- a method of transmitting ACK/NACK efficiently in accordance with a number of OFDM symbols used for the ACK/NACK signal transmission is described.
- FIG. 8 is a diagram for explaining a method of transmitting ACK/NACK in case of using at least 2 OFDM symbol zones for ACK/NACK transmission according to one preferred embodiment of the present invention.
- FIG. 8 shows an example that resources are more efficiently utilized by decrementing a frequency axis repetition count of ACK/NACK signals multiplexed by CDMA in case that the number of OFDM symbols for ACK/NACK signal transmission are incremented into two.
- ACK/NACK signals are repeated twice compared to four times in FIG. 6, as the number of OFDM symbols used for the ACK/NACK signal transmission is incremented, the use of four time-frequency resource domains is the same as the case of using a single OFDM symbol. Compared to FIG.
- frequency and/or time diversity can be obtained by carrying out FDMA and/or TDMA on the 1-bit control signal transmission side by side and by distributing to transmit a plurality of control signals for a specific UE on each time-frequency domain.
