## Abstract

A method and apparatus are provided for encoding an information object. The method includes storing the information object in a buffer; generating a sampling set including bits selected from the buffer according to a predetermined rule and bits randomly selected from the buffer; generating control channel data including information on the sampling set; and modulating the sampling set and the control channel data.

## Claims

### Claim 1

A method for encoding an information object, the method comprising the steps of:
storing the information object in a precoder buffer;
generating a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer;
generating control channel data including size information on the information object; and
modulating the sampling set and the control channel data.

### Claim 2 (depends on 1)

The method of claim 1, wherein the control channel data further includes a sampling set number of the sampling set.

### Claim 3 (depends on 1)

The method of claim 1, further comprising repeating and interleaving bits of the information object, before storing the information object.

### Claim 4 (depends on 3)

The method of claim 3, further comprising encoding the repeated and interleaved bits of the information object by using a predefined code, before storing the information object.

### Claim 5

An apparatus for encoding an information object, the apparatus comprising:
a precoder buffer; and
an encoder configured to:
store the information object in the precoder buffer;
generate a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer;
generate control channel data including size information on the information object; and
modulate the sampling set and the control channel data.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the control channel data further includes a sampling set number of the sampling set.

### Claim 7 (depends on 5)

The apparatus of claim 5, wherein the encoder is configured to repeat and interleave bits of the information object, before storing the information object.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the encoder is configured to encode the repeated and interleaved bits of the information object by using a predefined code, before storing the information object.
