Abstract
New multiplexing UL structures for supporting legacy system are provided. A 16m system of diversity mode can be multiplexed with 16e system in PUSC mode in FDM manner with the same tiles/permutation rules. A 16m system can be multiplexed with 16e system in AMC mode in FDM and/or TDM manner. The time length of multiplexed 16e PUSC packets and/or 16m packets can be extended to more than two sub-frames for UL coverage. A PRU for 16m system may consists of 16 sub-carriers by 6 OFDMA symbols, 18 sub-carriers by 6 OFDMA symbols, or 20 sub-carriers by 6 OFDMA symbols when FDM is used.
