Hello. I have two questions In IEEE 802.16, Base Station
allocate Uplink bandwidth per Subscriber Station. I know that Subscriber Station recognize
through UL-MAP_IE for allocated uplink bandwidth. Does many UL-MAP_IEs for same
Subscriber Station exist in a uplink subframe? Does uplink bandwidth for a
subscriber station split into multiple UL-MAP_IE in a uplink subframe? Is this possible? I wonder how to transmit bandwidth
request packets when many connections exist in a subscriber station. Assume all
connection is BE (Best Effort) and bandwidth request is based on contention. Does bandwidth request packets transmit
per connection? What is criteria of selecting connection
for requesting bandwidth? Regards, Sang-Jin Kim |
