same allocation id has another Allocation Block Duration Discussion: Allocation Block Duration field within TDD Slot Structure element TDD Slot Structure element is not necessarily sent together with Extended Schedule element since these two elements can be sent with different periodicity. Moreover, the main function of the Allocation Block Duration field within Extended Scehdule element is to notify legacy STAs that this period of time is for TDD devices. For TDD devices, this duration information in TDD Slot Structure elment can be shorter than or equal to the duration indicated in Extended Schedule element. As a result, we need to include the TDD SP duration information in TDD Slot Structure element in case a STA misses the Extended Schedule element and therefore not able to understand the timing structure included in TDD Slot Structure element. In order to avoid confusion, suggest to change the field name from Block Duration” to SP Block “Allocation “TDD Duration” Slot Structure Time field within TDD Slot Structure element This field is different with the Allocation Start field. The Slot Structure Start Time field indicates when the associated timing structure of a TDD SP takes effect. This time is not necessarily the same as the Alocation Start time. Allocation ID within TDD Slot Structure element The Allocation ID is needed here. When there are more than one TDD SPs allocated in the BI, the Allocation ID would be used to associate a TDD SP with its structure. Allocation Block Duration Validity field within TDD Slot Structure element Agree that this field can be removed. Proposed resolution: Revised.
