Abstract

A number of techniques to enhance the spectral efficiency of GSM/EDGE networks are currently being developed to meet the rapid growth in the use of mobile communications. Adoption of such features could render even one-reuse configurations blocking limited. To allow future networks to maximize spectral efficiency by remaining interference limited, the channel allocation tiering (CHAT) concept has been devised. With CHAT, methods to create and manage intracell interference are introduced. The CHAT concept is presented and its components evaluated by means of link and system simulations. Introduction of a CHAT configuration in a simulated GSM full-rate speech network is shown to lead to a 4-fold increase in downlink capacity and the effects of intracell interference are strongly mitigated
