Abstract

This invention is in the field of self-organizing wire- less networks. It describes a routing protocol which, amongst other advantages, allows the joint exploitati- on of both, joint-detection (JD) and joint- transmission (JT). The main principle is that the same information is routed to mobile stations (MS) (prima- rily remotely located ones) via different paths. This routing protocol utilises the time-division duplex (TDD) mechanism (see fig. 1). The data on the mul- tiple transmission links is processed using the JT technique in order to achieve interference reduction at the receiver. In conventional systems that use JT several access points (AP) are connected via cables to a central unit (CU). This invention avoids extra cabling completely. The main idea is depicted below. fig. 1
