In some examples, the transmitting device may indicate a peak to average power ratio (PAPR) in the PSIM, such as a PAPR of a maximum peak in the data signal. Based on the indicated PAPR, the receiving device may perform a calculation to determine the amplitude offset for reconstructing the data message.

  • Guard-space timestamp point for precision synchronization in 5G and 6G
    Patent number: 11722980
    Abstract: High-frequency communications in 5G and especially 6G will require precise synchronization of user devices with the base station, including setting the user device clock time and clock rate. The base station can assist user devices by periodically providing a guard-space timestamp point, at which a phase or amplitude of the timing signal abruptly changes in the middle of the guard-space of a particular resource element or a particular OFDM symbol. A receiver can determine precisely the time of arrival of the timestamp point, and correct its clock setting to agree with the time of the timestamp point. The receiver can then provide uplink messages aligned with the base station's clock, by adding a previously determined timing advance to each uplink transmission. In addition, the user device can measure two guard-space timing signals with a predetermined separation, thereby adjusting the clock rate.

  • System and method for bandwidth utilization
    Patent number: 11690060
    Abstract: Methods of bandwidth utilization are provided. Within a scheduling bandwidth, which may be an entire carrier bandwidth or a sub-band, scheduling is used to reserve a guard zone at the edge of the scheduled bandwidth. This can be based on the frequency localization capabilities of a transmitter that is to be scheduled. The guard zone may be defined to a resolution that is the same as the scheduling resolution in which case the guard zone is defined entirely through scheduling. Alternatively, the guard zone may be defined to a resolution smaller than the scheduling resolution in which case scheduling and further signaling may be employed to define the guard zone.

  • Synchronization channel and system acquisition for internet of things communications in a shared spectrum
    Patent number: 11683770
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a first synchronization sequence and generate a second synchronization sequence based at least in part on the first synchronization sequence. The base station may map the first synchronization sequence to a first resource block of a synchronization channel associated with a first frequency sub-band of a shared radio frequency spectrum band and the second synchronization sequence to a second resource block associated with a second frequency sub-band of the synchronization channel. The base station may then transmit the first synchronization sequence and the second synchronization sequence concurrently over the synchronization channel using the first resource block and the second resource block according to the mapping. In some cases, the second synchronization sequence may be generated by applying a first phase shift to the first synchronization sequence.

  • Methods of data communication in multipath channels
    Patent number: 11646913
    Abstract: Fiber, cable, and wireless data channels are typically impaired by reflectors and other imperfections, producing a channel state with echoes and frequency shifts in data waveforms. Here, methods of using pilot symbol waveform bursts to automatically produce a detailed 2D model of the channel state are presented. This 2D channel state can then be used to optimize data transmission. For wireless data channels, an even more detailed 2D model of channel state can be produced by using polarization and multiple antennas in the process. Once 2D channel states are known, the system turns imperfect data channels from a liability to an advantage by using channel imperfections to boost data transmission rates. The methods can be used to improve legacy data transmission modes in multiple types of media, and are particularly useful for producing new types of robust and high capacity wireless communications using non-legacy data transmission methods as well.
