Wireless communication transceiver and wireless communication method
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.
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,
wherein a first set of Non-Uniform Constellation patterns correspond to a New Data Indicator and a second set of Non-Uniform Constellation patterns correspond to a retransmission.
2. 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.
3. The wireless communication transceiver of claim 1 , wherein the indicator is contained in a Downlink Control Information.
4. 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.
5. The wireless communication transceiver of claim 4 , wherein the index is a Modulation and Coding Scheme index.
6. The wireless communication transceiver of claim 4 , wherein the reference lookup table provides the first set of Non-Uniform Constellation patterns and the second set of Non-Uniform Constellation patterns.
7. The wireless communication transceiver of claim 3 , wherein the indicator is an indicator indicating a redundancy version for a Hybrid Automatic Repeat Request retransmission.
8. 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.
9. 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.
10. 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.
11. The wireless communication transceiver of claim 1 , wherein the indicator is contained in an Uplink Control Information.
12. 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.
13. The wireless communication transceiver of claim 1 , wherein the indicator is included in a Channel State Information.
14. The wireless communication transceiver of claim 1 , wherein the wireless communication transceiver is a base station or a user equipment.
15. The wireless communication transceiver of claim 1 , wherein the circuitry is further configured to
in response to a transmission failure of a data packet due to a signal-to-noise ratio (SNR) radio condition at which the Non-Uniform Constellation patter is not targeted, use a Non-Uniform Constellation pattern that targets a lower SNR or a higher SNR.
16. 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,
wherein a first set of Non-Uniform Constellation patterns correspond to a New Data Indicator and a second set of Non-Uniform Constellation patterns correspond to a retransmission.
