UPLINK TIMING ERROR REDUCTION METHOD AND APPARATUS |
摘要 |
The technology presented in this disclosure pertains to telecommunication. For example, there is presented a method of operating a wireless terminal 30. A timing advance command (TAC) control element (CE) is received over a radio interface (from a network node 28). Upon receipt of the TAC CE, the method continues by updating UL (uplink) transmission timing for cells in a timing advance (TA) group even when a TA timer for the associated TA group is not running. |

1. A wireless terminal comprising:
a communications interface configured to receive a timing advance command control element over a radio interface from a network node; and an uplink (UL) transmission timing update unit configured, upon receipt of the timing advance command control element, to update UL transmission timing for cells in a timing advance (TA) group even when a TA timer for the associated TA group is not running. |
