Performing multiple timing advance adjustments in a carrier aggregation communication system

摘要

Technology for performing multiple timing advances in a carrier aggregation communication system is disclosed. A method comprises communicating a random access preamble from a UE to an eNodeB via a PCell associated with a selected component carrier of the carrier aggregation. A Random Access Response (RAR) is received at the UE from the eNodeB for the PCell. The RAR contains a timing advance adjustment instructing the UE to adjust a timing of a PCell wireless communication. A request is received at the UE to adjust a timing of an SCell communication. A random access preamble is communicated to the UE via the SCell. An RAR is received at the UE from the eNodeB for the SCell to adjust a timing advance of the SCell wireless communication.

1. A method for adjusting a timing of a wireless communication in a wireless communication system configured for carrier aggregation, comprising:
communicating a random access preamble in an uplink from a user equipment (UE) to an eNodeB via a Primary Cell (PCell) associated with a selected component carrier of the carrier aggregation; receiving a Random Access Response (RAR) at the UE from the eNodeB for the PCell, wherein the RAR contains a timing advance adjustment instructing the UE to adjust a timing of a PCell wireless communication; receiving a request at the UE to adjust a timing of a Secondary Cell (SCell) wireless communication associated with a second component carrier of the carrier aggregation; communicating a random access preamble in an uplink from the UE to the eNodeB via the SCell; and receiving an RAR at the UE from the eNodeB for the SCell, wherein the RAR contains a timing advance adjustment instructing the UE to adjust a timing of the SCell wireless communication.
