## Abstract

A wireless communication transceiver comprising circuitry configured to send or receive, via a wire-less link, an indicator indicating a Non-Uniform Constellation pattern out of a plurality of Non-Uniform Constellation patterns.

## Claims

### Claim 1

A wireless communication transceiver comprising circuitry configured to send or receive, via a wireless link, an indicator indicating a Non-Uniform Constellation pattern out of a plurality of Non-Uniform Constellation patterns.

### Claim 2 (depends on 1)

The wireless communication transceiver of claim 1, wherein the circuitry is further configured to exchange, via the wireless link, information being modulated using the Non-Uniform Constellation pattern indicated by the indicator.

### Claim 3 (depends on 1)

The wireless communication transceiver of claim 1, wherein the indicator is contained in a Downlink Control Information.

### Claim 4 (depends on 3)

The wireless communication transceiver of claim 3, wherein the indicator is an index to an entry of a reference lookup table, the reference lookup table providing Non-Uniform Constellation patterns for respective indices.

### Claim 5 (depends on 4)

The wireless communication transceiver of claim 4, wherein the index is a Modulation and Coding Scheme index.

### Claim 6 (depends on 4)

The wireless communication transceiver of claim 4, wherein the reference lookup table provides a first set of Non-Uniform Constellation patterns for a New Data Indicator being set and a second set of Non-Uniform Constellation patterns for the New Data Indicator being not set.

### Claim 7 (depends on 3)

The wireless communication transceiver of claim 3, wherein the indicator is an indicator indicating a redundancy version for a Hybrid Automatic Repeat Request retransmission.

### Claim 8 (depends on 1)

The wireless communication transceiver of claim 1, wherein the circuitry is further configured to send or receive, via the wireless link, information indicating a capability of encoding and decoding Non-Uniform Constellation patterns.

### Claim 9 (depends on 8)

The wireless communication transceiver of claim 8, wherein the circuitry is further configured to send or receive the information indicating a capability of encoding and decoding Non-Uniform Constellation patterns using Radio Resource Control signaling.

### Claim 10 (depends on 8)

The wireless communication transceiver of claim 8, wherein the information indicating a capability of encoding and decoding Non-Uniform Constellation patterns is contained in a System Information Block.

### Claim 11 (depends on 1)

The wireless communication transceiver of claim 1, wherein the indicator is contained in an Uplink Control Information.

### Claim 12 (depends on 1)

The wireless communication transceiver of claim 1, wherein the indicator is an indicator indicating a group of Resource Blocks used for exchanging the information, and wherein a Non-Uniform Constellation pattern is assigned to a respective group of Resource Blocks.

### Claim 13 (depends on 1)

The wireless communication transceiver of claim 1, wherein the indicator is included in a Channel State Information.

### Claim 14 (depends on 1)

The wireless communication transceiver of claim 1, wherein the wireless communication transceiver is a base station or a user equipment.

### Claim 15

A wireless communication method comprising signaling, via a wireless link, from a first transceiver of the wireless link to a second transceiver of the wireless link, an indicator indicating a Non-Uniform Constellation pattern out of a plurality of Non-Uniform Constellation patterns.
