2. doc.: IEEE 802.11-11/1017r1 July 2011 Huawei Submission Abstract This submission is a preliminary submission for discussions on the functional requirements for TGah, based on the smart meter use case. July 2011

3. doc.: IEEE 802.11-11/1017r1 July 2011 Huawei Submission Issues to be discussed (1) 802.11ah Network discovery –There may be many BSSs in the same area and each BSS may support multiple services. –STA should be able to find the proper AP easily 802.11 Association & Authentication –Collision is expected to become more serious with the increasing number of STAs compete for association & authentication –Contention-free period should be considered for Association & Authentication to reduce collision July 2011

4. doc.: IEEE 802.11-11/1017r1 July 2011 Huawei Submission Issues to be discussed (2) STA initial configuration –STA should report data periodically according to the service feature, for use case such as smart meter –STA need to be configured with duty cycle, server address and etc during initial link setup Data report –STA usually has very few data to report for each duty cycle –Non-IP solution should be considered to improve throughput efficiency and reduce the frame length to save power July 2011
