The document summarizes highlights from RAN#64 that are relevant to RAN1. It notes that all CRs for HSPA and LTE Rel-12 were approved. It describes the status of work items and study items on HSPA enhancements, LTE Rel-12 features including further downlink MIMO enhancement and small cell enhancements, and a new Rel-13 study item on indoor positioning enhancements. Work items on DCH enhancement, UMTS heterogeneous networks, and various LTE Rel-12 features including device-to-device proximity services and small cell enhancements were extended with a targeted September completion date.

2. 2
HSPA
• All CRs approved
• Rel-12
– Study on Scalable UMTS by filtering
• SI is stopped with 85% completion level
• There is one Note in RAN report that “The study item resulting in TR 25.701 has been
closed but not all open issues have been addressed. Further details can be found in
this final status report of the SI.”
– DCH enhancement
• WI is extended with targeting September completion
• Updated WID (RP-140771) is approved
– UMTS Heterogeneous Networks
• WI is extended with September completion date

LTE: Rel-12 (1)
• All CRs approved
• Rel-12
– Further Downlink MIMO Enhancement for LTE-Advanced
• Core part completed
– Further Enhancements to LTE TDD for DL-UL Interference Management and Traffic
Adaptation
• Core part completed

4. 4
LTE: Rel-12 (2)
• Rel-12 (cont.)
– Small Cell Enhancements – Physical-layer Aspects
• WI is extended with targeting September completion
• Way forward related to small cell on/off (RP-141031) is approved with following contents
– Spend no more than 1 TU in RAN1#78 to discuss this open issue:
» “Investigate detailed solution(s) of new L1 procedure for activated Scell operating on/off that further
reduces transition time”
– If a consensus cannot be reached on a complete solution during this limited time, then there will be no new
L1 procedure for activated SCell operating on/off in Rel-12 due to time constraints.
– (RAN2-led) Dual connectivity for LTE
• WI is extended with targeting September completion
• Allocate RAN1 time unit in RAN1 #78 meeting
