 11.5 Mbps in the uplink. Evolved EDGE: It upgrades the existing EDGE technology to support peak date rates of 1 Mbps. Higher Modulation: Release 7 provides 64QAM in the downlink (HSDPA) and 16QAM in the uplink (HSUPA) in the FDD mode. MIMO: The Smart Antenna technique called MIMO (multiple input multiple output) functionality was integrated in UTRA (FDD and TDD) to improve capacity and spectral efficiency. RX Diversity and LMMSE Equalizer: The performance of higher code (10 code) capability UE classes (i.e., categories 7 and 8) was further improved with the introduction of reference receiver LMMSE4 chip-level equalizer and a reference receiver with receive diversity. The benefits of Rx diversity are applicable to all (Ior/Ioc) geometries while the LMMSE augments the benefits of Rx diversity when effectively operating at the higher (Ior/Ioc) geometries. The combined reference receiver can be based on the receiver structures that were used for defining HSDPA performance improvements in Rel-6. CS voice over HSPA: Rel-7 provides several improvements for running circuit switched voice service over HSPA to boost capacity and reduce battery consumption of the devices. Additional Spectrum: 3GPP has specified three additional bands namely Band III (UMTS 1800), Band IV (UMTS 1.7/2.1) and Band IX (UMTS 1700). 3GPP TDD mode was specified for operation in the band 2500-2690 MHz with 7.68 Mcps. UMTS900: Rel-7 also introduces UMTS in the 900 MHz and provides the necessary UMTS900 specifications. IMS Enhancements: The enhancements include global user agents URIs (universal resource identifier) in the IMS to support multiple UEs to register with the same Public User Identity, support for multimedia telephony service for IMS, and SO on. Location Services: Uplink TDOA (Time Difference of Arrival) location method has been included for UTRAN. Assisted-GALILEO has also been introduced in Rel-7. MBMS Enhancements: Although the basic MBMS functionality already exists in Rel-6 MBMS, additional requirements are added to enhance the curre
