A transmit receive point in a first group of TRPs transmits with a first synchronization sequence. A TRP in a second group of TRPs transmits with a second synchronization sequence, the first and second synchronization sequences being different from each other. The TRPs of the first group share a common first characteristic and the TRPs of the second group share a common second characteristic. The transmission of the first synchronization sequence conveys the first common characteristic, and the transmission of the second synchronization sequence conveys the second common characteristic.

  • Patent number: 11050503
    Abstract: Different numerologies may be used to communicate orthogonal frequency division multiplexing (OFDM)-based signals over different frequency sub-bands of a given carrier. This may allow the OFDM-based signals to efficiently support diverse traffic types. In some embodiments, the numerology of OFDM-based signal depends on a bandwidth of the frequency sub-band over which the OFDM-based signals are transmitted. In some embodiments, the OFDM-based signals are filtered OFDM (f-OFDM) signals, and the pulse shaping digital filter used to generate the f-OFDM signals allows the receiver to mitigate interference between adjacent f-OFDM signals upon reception, thereby allowing f-OFDM signals to be communicated over consecutive carriers without relying on a guard band.

  • Patent number: 11051208
    Abstract: Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

  • Publication number: 20210185698
    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.

  • Patent number: 11039435
    Abstract: Methods and devices are provided for communicating data in a wireless channel. In one example, a method includes adapting the transmission time interval (TTI) length of transport container for transmitting data in accordance with a criteria. The criteria may include (but is not limited to) a latency requirement of the data, a buffer size associated with the data, a mobility characteristic of a device that will receive the data. The lengths may be manipulated for a variety of reasons; such as for reducing overhead, satisfy quality of service (QoS) requirements, maximize network throughput, etc. In some embodiments, TTIs having different TTI lengths may be carried in a common radio frame. In other embodiments, the wireless channel may partitioned into multiple bands each of which carrying (exclusively or otherwise) TTIs having a certain TTI length.
