Abstract: This disclosure relates to methods for transmission preemption in a wireless local area network. A downlink transmission may be performed by an access point device on a first wireless link. Signaling requesting or indicating preemption of the downlink transmission may be provided from a non-access point device to the access point device on a second wireless link. The downlink transmission may be preempted based at least in part on the signaling requesting or indicating preemption of the downlink transmission.

Abstract: A data optical transmission apparatus utilizing multiplexer/demultiplexer mode for multiplexing and transmitting 24 channels of 51.84 Mbps frame, and for demultiplexing the frame data for realigning as twenty four pieces of frame data of 51.84 Mbps. The data optical transmission apparatus of the present invention utilizes a synchronous transmission apparatus of which transmission basic unit is 51 Mbps. The synchronous transmission apparatus has a convenience transmission means of simple bit interleaving mode and eight application software IC (ASIC) each of which has three 51 Mbps framers/reframers. By using the framers/reframers, twenty four channels of 51 Mbps frame data are produced, which are multiplexed for being transmitted as 1.2 Gbps data. At the receiving section, data of 1.2 Gbps is demultiplexed by 24 to 1, thus extracting twenty four pieces of frame data of 51 Mbps. The extracted 51 Mbps frame data is produced in the order reverse to the order of transmission.
