レイテンシ制御
Document Type and Number:
Japanese Patent JP7185060
Kind Code:
B2
Abstract:
Disclosed is a latency control method of a transmitter apparatus adapted for transmission of a plurality of packets under clear channel assessment requirements and latency requirements. The method comprises determining a maximum required time for clear channel assessment for the plurality of packets and determining a duration of time related to the determined maximum required time. For example, the duration of time may be determined as being equal to the determined maximum required time for clear channel assessment plus an offset. The offset may be equal to zero, or may be equal to a positive value. In some embodiments, the offset may be equal to, or larger than, a duration of another packet (which is not comprised in the plurality of packets). The method also comprises enforcing, for each packet of the plurality of packets, the determined duration of time to elapse after completion of transmission of the packet, before transmission of a subsequent packet of the plurality of packets is initiated. Corresponding latency control apparatus, transmitter apparatus, communication device and computer program product are also disclosed.
