Disclosed is a method to demodulate messages according to two different modulation schemes in 5G and 6G, and thereby identifying which message elements are likely faulted. The two modulation schemes are QAM in which the signal is a sum of two orthogonal amplitude-modulated “branch” signals, and classical amplitude-phase modulation in which each message element's raw signal is both amplitude and phase modulated. The two schemes have similar information density but different noise sensitivities. Therefore, a receiver can compare the demodulated message using one modulation scheme to the same message demodulated according to the other modulation scheme, and flag any message elements that demodulate differently. In addition, one modulation scheme may be more effective than the other depending on conditions.

A system for monitoring cellular communications including a passive sensor device, processors, and memory devices. The memory devices having instructions that cause the processors to identify active downlink channels using a first radio to monitor each channel in a cellular spectrum and store downlink channel information, including configuration data, for each of the identified active downlink channels. The processors identify active uplink channels using a second radio to monitor each channel in the cellular spectrum and store uplink channel information for each of the identified active uplink channels. The processors correlate one of the active uplink channels with a corresponding active downlink channel and tune a third radio to the active uplink channel using the configuration data for the corresponding active downlink channel. The processors also tune a fourth radio to the active downlink channel corresponding to the at least one active uplink channel using the corresponding configuration data.

In an example, a User Equipment (UE) receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier (G-RNTI) for a Hybrid Automatic Repeat Request (HARQ) process. In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time (RTT) timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier (C-RNTI) for the HARQ process. The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer. The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer. The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process. In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer.

Aspects of the subject disclosure may include, for example, a device in which a processing system detects installation of a subscriber identity module (SIM) on a communication device configured for connection to the network; the SIM includes a radio policy manager (RPM) provided by the network operator to manage network policies. The system also monitors connection of the communication device to the network and communications between the SIM and a processor of the communication device. The RPM determines whether the communication device is compliant with the network policies; if the communication device is not compliant with the network policies, the RPM causes the connection of the communication device to the network to be disabled. Other embodiments are disclosed.
