Abstract: A wireless receiver in 5G and 6G can localize message faults by defining an “acceptance region” surrounding each of the predetermined allowed modulation states of a modulation scheme. Then, upon receiving a message, the receiver can measure (or calculate from the I and Q branches) the received amplitude and phase of the waveform signal in each message element. If the received amplitude and phase are within one of the acceptance regions, the message element according to the allowed state in that acceptance region. If the received amplitude and phase are not within the acceptance region of any of the allowed states, that message element is faulted. In addition, the receiver can increment an amplitude fault tally and a phase fault tally according to which parameter—amplitude or phase—is outside the acceptance regions, thereby greatly simplifying recovery of the message without a retransmission.

Abstract: 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.

Abstract: A method includes a first device that sends a spectrum sensing request frame to a second device, where the spectrum sensing request frame requests the second device to perform spectrum sensing. The second device sends a request acknowledgment frame which, is used to acknowledge that the spectrum sensing request frame is received. The second device performs spectrum sensing based on the at least one spectrum sensing parameter, to obtain a spectrum sensing result. The second device sends a spectrum sensing feedback frame to the first device, where the spectrum sensing feedback frame is used to feed back the spectrum sensing result. The first device sends the spectrum sensing request frame, so that the second device can perform spectrum sensing based on information carried in the spectrum sensing request frame, and the first device can obtain the accurate spectrum sensing result of the second device.

Abstract: A user equipment (UE) may obtain high-priority data (e.g., low latency data) to be transmitted to a base station. In some scenarios, the base station may be transmitting downlink transmissions to the UE or to a different UE, or may be receiving uplink transmissions from the UE or from the different UE. The described aspects enable the UE to timely transmit the high-priority data in these scenarios. In one example, the described aspects enable the UE to transmit, to the base station, while the base station performs one or more scheduled downlink transmissions to the UE or to the different UE, at least one of the high-priority data via a first uplink beam from a set of uplink beams for unscheduled uplink transmissions or an unscheduled data indication indicating that the high-priority data is to be transmitted without an uplink grant.

Abstract: 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.

Abstract: A repetition unit (212) performs a repetition for mapping a data signal and a demodulation reference signal (DMRS) repeatedly at a symbol level over a plurality of subframes. A signal allocation unit (213) maps, in the a plurality of subframes, the repeated DMRS to symbols other than symbols corresponding to an SRS resource candidate, which is a candidate for a resource to which a sounding reference signal (SRS) to be used to measure an uplink received signal quality is to be mapped. A transmission unit (216) transmits an uplink signal (PUSCH) including the DMRS and the data signal over the a plurality of subframes.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit semi-persistent scheduling (SPS) messages to a set of user equipments (UEs) using respective resources corresponding to each UE. The base station may receive, from each of a subset of UEs from the set of UEs, a negative acknowledgement (NACK) message associated with the SPS messages. The base station may transmit a group downlink control message including information associated with a downlink resource configuration for retransmission of the respective SPS messages to the subset of UEs. The base station may retransmit SPS messages to each of the subset of UEs using the downlink resource configuration.
