Abstract (en)
[origin: WO2013112952A1] Introduction of a timing advance group concept into LTE TS 36.321 for release 11. A timing advance group (TA group) comprises up to five cells. For each TA group the UE only needs a single TA timer. The initial timing alignment is achieved by a base station initiated RACH pro¬ cedure. The configuration of multiple TA groups depends on the UE capabilities report which defines Multi-TA capability of the UE based on each supported band combination A base station receives radio capability parameters from a wireless device on a first signaling bearer on a primary cell. The radio capability parameters comprise a first sequence of radio configuration parameters. A first radio configuration parameter in the first sequence comprises a first parameter indicating whether multiple timing advance groups are supported for a first band combination. The first band combination is in a second sequence of band combinations. The index of the first radio configuration parameter in the first sequence determines the index of the first band combination in the second sequence.
