Abstract: This document discloses a solution for a link negotiation procedure in a wireless network. According to an aspect, the solution comprises in a first node (100) of a wireless network: determining (300) that a target node of the wireless network is not reachable with a point-to-point transmission; transmitting (302) broadcast transmission requesting a relay connection to the target node; receiving (304) on a given frequency a response from a second node of the wireless network, the response indicating capability to relay transmissions to the target node; transmitting (306) data to the second node, the being data intended to the target node and receiving (308) an acknowledgement from the second node that the data has been successfully transmitted to the target node.

Abstract: The invention concerns a system for transmitting information in a digital radio network system (12) between at least two modes of operation, which may be—a direct mode operation (DMO) between two terminal devices (10.1, 10.2) operating independently of the physical radio network system (21) and—a trunked mode operation (TMO) supporting distribution of network resources and operating in the physical radio network system (21). The transmission takes place with the aid of a special gateway unit (22), wherein the gateway unit (22)—listens to each or to a chosen mode of operation (DMO, TMO),—receives the transmission occurring in one mode of operation (TMO, DMO), and—transmits the received transmission to the other mode of operation (DMO, TMO). The gateway unit (22) is formed of two terminal devices (12.1, 12.2) supporting each mode of operation, and whose data transfer interface (23.3*, 23.
