  • the highest TAG index value is allocated without explicit indication. That is, if the TAG index starts from 0, the TAG index of the PTAG including the primary carrier is 0.

  • the eNB provides the TAG index only in the configuration information of the SCell 1. If the configuration of the SCell 2 received from the eNB does not include a TAG index, then the TAG of the SCell 2 follows the TAG of the SCell 1 configured before the SCell. With this approach, it is possible to provide the information on the TAG to which each secondary carrier belongs without including the TAG index in the configurations of each respective secondary carrier.
  • the timing synchronization is performed using the TAC MAC CE on a per TAG basis. If the TAC MAC CE is transmitted per TAG, the number of TAC MAC CEs increases in proportional to the number of the TAG so as to be transmitted to the UE as distributed across MAC PDUs.

If it is possible to transmit the TAC MAC CEs of multiple TAGs in fewer extended TAC MAC CEs, this can improve the resource efficiency. For example, the resource efficiency may be improved if the TAC MAC CEs of multiple TAGs are transmitted in one extended TAC MAC CE.
