Contribution to resource management in cellular access networks with limited backhaul capacity
Galeana Zapién, Hiram (Universitat Politècnica de Catalunya, 2011-02-25)
Tesi
Accés obertLa interfaz radio de los sistemas de comunicaciones móviles es normalmente considerada como la única limitación de capacidad en la red de acceso radio. Sin embargo, a medida que se van desplegando nuevas y más eficientes ... -
Enhanced base station assignment approach for coping with backhaul constraints in OFDMA-based cellular networks
Galeana Zapién, Hiram; Ferrús Ferré, Ramón Antonio (2010-04)
Text en actes de congrés
Accés obertIn this paper we extend the base station (BS) assignment problem to incorporate backhaul related constraints into the assignment decision. This is motivated by the fact that the deployment of more spectral efficient ... -
Spectrum availability in indoor locations for opportunistic spectrum access in dense urban scenarios
Novillo Parales, Francisco Vicente; Galeana Zapién, Hiram; Ferrús Ferré, Ramón Antonio; Agustí Comes, Ramon (2009-04)
Comunicació de congrés
Accés obertThis paper analyses the possibility to exploit opportunistic spectrum access (OSA) for short-range radio communication systems within indoor locations in dense urban areas. In particular, considering the service area of ... -
User allocation algorithm with rate guarantees for multi-rate mobile networks with Backhaul Constraints
Galeana Zapién, Hiram; Lainz, Anna; Ferrús Ferré, Ramón Antonio (2009-04)
Text en actes de congrés
Accés obertThe optimization of the base station (BS) assignment problem in mobile access networks is a primary task towards enabling efficient utilization of network resources. So far, this problem has been mainly studied in terms ...
