Abstract	In a conventional organization of TDMA based cellular networks, the offered traffic is limited by both interference and radio resource management (RRM) issues. To overcome that limitation in very dense capacity areas (hot-spots), an original base station sub-system (BSS) organization with distributed coverage is proposed. In such a system, the base transceiver station (BTS) functionality is split between a central point, the BTS concentrator (BTSC) and several radiating elements (relays). For each communication, a set of relays connected to the same BTSC is assigned for both, synchronous broadcast of the same signal on the downlink, and demodulation of messages transmitted by the mobile station (MS) on the uplink. An optimization of the spectrum efficiency is achieved if one provides radio coverage only where needed, namely, in the vicinity of the MS. This however requires the addition of new RRM algorithm in the BSS as well as means to track the MS trajectory during its communication. This paper focuses on this last issue and several procedures performing best server-relay selection based on uplink signal measurements in an urban Manhattan-like environment are analyzed.
