PREEMPTION TECHNIQUES FOR TRANSMITTING HIGH PRIORITY PACKETS

This abstract first appeared for US patent application 20250081239 titled 'PREEMPTION TECHNIQUES FOR TRANSMITTING HIGH PRIORITY PACKETS

Original Abstract Submitted

a method for transmitting a high priority (hp) packet from a first wireless device to a second wireless device is described. the method includes determining the presence of an hp packet for uplink transmission; determining that a communications link that uses a wireless medium for transmitting the hp packet is busy; generating a preemption request message in a frame; and transmitting the frame with the preemption request message to the second wireless device. the first wireless device can receive from the second wireless device an indication that the preemption request was accepted, such as by receiving a trigger frame with resource allocation for transmitting the hp packet or an indication of the end of a contention free period, to allow the first wireless device to contend for channel access to transmit the hp packet.
