Assessment of access selection and transmit diversity in (non) cosited multi-access networks
conference paper
Multi-access networks integrate a number of radio accesses (RAS) over which a data flow may be transmitted. Considering the possibility of multi-radio transmit diversity (MRTD), where a given flow may be assigned multiple RAS either in parallel or in a switched mode, we investigate mechanisms for joint RA selection and scheduling of data flows onto the selected RAS. We introduce the active set concept for multi-access networks, consisting of a subset of the available RAS that are chosen by a user for potential handling of its data flow and establish the latitude for access selection. The performance impact of distinct access selection schemes is assessed in multi-access networks, considering different scenarios in terms of the degree of non cositing, the traffic load and the number of available RAS. Among the key results, we demonstrate that a significant degree of non cositing is beneficial and that the use of MRTD is fruitful in pursuing performance targets of operational relevance. © 2007 IEEE.
