A plurality of data streams may be arranged in a specified order, so that joint encoding without feeding back information can be implemented, and transmission close to a channel capacity can be implemented.
Modulation Schemes for Recovering Collided States in 5G/6G
When two different messages are transmitted at the same time in 5G or 6G, the message is “collided”. The resulting interference causes a message fault, necessitating a costly retransmission. Disclosed is a modulation scheme in which the modulation states are configured so that a message element can be collided by an intruder message, yet the receiver can still recover the original message element. In other cases, depending on the colliding states, the receiver can narrow the possible values of each faulted message element to just two or three possibilities, thereby greatly reducing the amount of time required for testing each combination against an error-detection code. Especially under high-noise conditions, the collision-proof modulation scheme may enable enhanced throughput by identifying and mitigating the faulted message element, and may thereby avoid unnecessary retransmissions.

MITIGATION OF COMMUNICATION SIGNAL INTERFERENCE USING ADAPTIVE TRANSMIT POWER
In some embodiments, a method for mitigating interference in a channel having multiple users includes: transmitting, by a transmitter, a signal of interest (SOI) to a sequential interference cancellation (SIC) receiver at a transmit power; determining a packet drop rate as seen by the receiver; and decreasing the transmit power in response to determining the packet drop rate exceeds a predetermined maximum packet drop rate. The transmitter's coding rate and/or modulation level may also be lowered based on the decrease in transmit power.

In some embodiments, a method for mitigating interference in a channel having multiple users includes: receiving a plurality of signals from a plurality of antenna elements, the received signals comprised of one or more interfering signals and a signal of interest (SOI); for each of the one or more interfering signals, beamforming the received signals to enhance the interfering signal, generating an estimate of the interfering signal, and adjusting the estimated interfering signal to undo the effects of beamforming; and subtracting each of the estimated interfering signals from each of the received signals to generate a plurality of interference-mitigated received signals.
HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK FOR OUTER LOOP ADAPTATION FOR 5G OR OTHER NEXT GENERATION NETWORK
Intelligent hybrid automatic repeat request (HARQ) feedback can better support link adaption. Thus, in addition to the traditional HARQ feedback, which is to relay acknowledgement (ACK) and negative acknowledgement (NAK) data based on a decoding result, a new state for the HARQ feedback can be represented as “ACK+”. Consequently, ACK+ can be used to indicate to the network that a modulation and coding scheme (MCS) of a current data packet is too conservative, and the user equipment (UE) is capable of supporting a more aggressive MCS.
