A system for determining a communication mode utilized by a transmitting node to transmit a data packet in a mesh network is provided. For example, a receiving node operates in a base communication mode to detect a pilot p of a data packet. The pilot prefix contains a signal with a predetermined frequency. In response to determining that the pilot prefix is detected, the receiving node detects a communication mode used to transmit the data packet based on preamble signals that are contained in a preamble of the data packet and are received after the detected pilot prefix. Once the communication mode is detected, the receiving node receives and processes the remaining portion of the data packet using the detected communication mode.

Proposed is a method for a first device performing wireless communication. The method may comprise the steps of: determining a first time domain and a second time domain with respect to a physical sidelink feedback channel (PSFCH) resource; performing sidelink data transmission to a second device through a resource on the first time domain; receiving, from the second device, hybrid automatic repeat request (HARQ) feedback associated with the sidelink data transmission; and on the basis of the HARQ feedback, performing sidelink data retransmission to the second device through a resource on the second time domain. For example, the first time domain may precede the PSFCH resource. For example, the second time domain may follow the PSFCH resource.
