摘要: Fields such as sequence numbers and length indicators of protocol layers are extended in extended headers so as to be backwards compatible with corresponding legacy headers. The existing fields of the legacy headers are not directly extended. Instead, existing fields are logically concatenated with other fields of the extended header. Whether the extended fields or legacy fields will be used can be determined dynamically based on current transport block size or semi-statically by higher layers.

摘要: Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.
