Dear all,
Hi, I have a question regarding macrodiversity. I have read that MBS can achieve macrodiversity by using the same symbol, modulation, subchannel etc in C80216e-04_275r1 & C80216e-04_359r3. My questions are:
1. I was confused about whether this macrodiversity is actually achieved by receiving the same burst from multiple base station (a.k.a single frequency network) on the same subchannel or is it achieved by receiving the same burst but on different subchannel (two synchronized stream) ?
2. Is single frequency network (SFN) possible in 802.16e ? By SFN I mean that an user can simultaneously receive the same burst from different base station on the same subchannel. Does the subchannelization like FUSC, PUSC impose any difficulty on it ?
Hope to hear from you guys shortly. Thanks in advance !
Regards,
Arthur.
