METHODS, USER EQUIPMENT AND EVOLVED NODE B FOR INACTIVATING UPLINK TRANSMISSIONS

摘要

It is presented a method, performed in a user equipment, UE, for inactivating uplink transmissions to an indicated cell. The method comprises the steps of: receiving a grouping command comprising the indicated cell from an evolved Node B, eNB, to assign the indicated cell to an inactive timing advance, TA, group, the inactive TA group indicating the UE to refrain from performing uplink transmissions; disassociating the indicated cell from a normal TA group, the normal TA group being associated with a TA value; and refraining from uplink transmission to the indicated cell.
