 which can be deployed as small UTRA and E-UTRA cells respectively. New positioning methods for EPS have been proposed. These include Control Plane LCS solution for EPS and OMA SUPL, 6 UE assisted and UE based A-GNSS (Assisted Global Navigation Satellite System), and SO on. Rel-9 specifies the architecture and procedures or procedure enhancements to support MBMS over E UTRAN. LTE Release 8 already supports single-layer beamforming (for receivers with single receive antenna)7 while multi-layer beamforming (for receivers with multiple receive antennas) is proposed for LTE Rel-9. HSPA+ Enhancements: Rel-9 further increases peak data rates of HSPA- that is, 84 and 23 Mbps in downlink and uplink respectively. These are achieved by combining MIMO with Dual-Cell HSDPA in the downlink and with Dual-Cell HUSPA in the uplink. Dual-cell HSDPA operation on non-adjacent carriers is under investigation. Further evolution of multi carrier HSDPA considers the usage of three to four 5 MHz downlink carriers for HSDPA transmission to an UE. These carriers can reside either in one frequency band or in two frequency 6 OMA (Open Mobile Alliance) SUPL 2.0 in an LTE context allows positioning using cell ID, enhanced cell ID, A-GPS and A-GNSS (Rel-8), etc. 7 Beamforming uses antenna array and signal processing techniques to maximize signal strength for subscriber devices. Next Generation Mobile Communications Ecosystem bands, for example, two adjacent 5 MHz carriers in one frequency band can be combined with a third 5 MHz carrier in a second frequency band. Dual-Cell HSUPA operation is specified in Rel-9 to enhance user experience and provide efficient load balancing. EPC and IMS Enhancements: The study item "IMS Evolution" focuses on the feasibility of enhancing the IMS network architecture by investigating architectural improvements. The "CS Domain Services over EPS" advancement define an architecture that is capable of extending the traditional MSC-Server based set of CS voice, supplementary and value-adding services and business prin
