25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

The MAC-ehs shall be configured with "TSN field extension" only when all the following conditions are met:

1> The UE is in CELL_DCH state;

1> either one of the following conditions are met:

2> two or more entries in the variable SECONDARY_CELL_HS_DSCH_RECEPTION are set to TRUE; or

2> the variable MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_STATUS is set to TRUE, and "MIMO mode with four transmit antennas only with dual stream restriction" is not configured; or

2> both of the following conditions are met:

3> an entry in the variable SECONDARY_CELL_HS_DSCH_RECEPTION is set to TRUE;

3> and the variable MIMO_STATUS or an entry in the variable SECONDARY_CELL_MIMO_STATUS is set to TRUE or the variable MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_STATUS or an entry in the variable SECONDARY_CELL_MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_STATUS is set to TRUE.

If all of the above conditions are met and "TSN field extension" is not configured for the MAC-ehs entity, the UE shall:

1> configure the MAC-ehs entity with "TSN field extension";

1> reset the MAC-ehs entity [15].

If any of the above conditions is not met and "TSN field extension" is configured for the MAC-ehs entity, the UE shall:

1> configure the MAC-ehs entity without "TSN field extension";

1> reset the MAC-ehs entity [15].
