The network node of a cellular network assigns a first part of a shared radio resource to a first User Equipment, UE, for uplink transmissions in the cell, and instructs the first UE to apply a first UE-specific Hybrid Automatic Repeat Request, HARQ, process for transmitting on the assigned first part. The network node also assigns a second part of the shared radio resource to a second UE for uplink transmissions in the cell, and instructs the second UE to apply a second UE-specific HARQ process for transmitting on the assigned second part, the second HARQ process being separate from the first HARQ process. The network node then receives data transmitted from the first UE on the assigned first part based on the first HARQ process and data transmitted from the second UE on the assigned second part based on the second HARQ process.

Techniques for presenting communication between two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for fast rate adaptation based on full duplex functionality, increasing link and network throughput. The present disclosure includes a method that provides a fast rate adaptation by leveraging full duplex in order to get immediate channel quality feedback.

A digital full-bandwidth direct-forwarding racon system and a working method adopt a direct forwarding architecture, which combines a digital broadband DRFM real-time forwarding technology and an encoding response architecture with dots replacing a line. A transmitting antenna and a receiving antenna operate independently and simultaneously, and directly and indiscriminately encode and forward all of the radar query signals in an operating frequency band, thus preserving complete waveform information while realizing a Morse encoding of the response information. The digital full bandwidth direct forwarding racon system is equivalent to a target with a special target characteristic, where when a radar signal within the operating frequency band irradiates the target, an echo signal with a specified Morse encoding modulation characteristic would be generated.
