    摘要: Methods, systems, and devices are described to support multiple timing advance groups for multi-carrier user equipment. Some embodiments provide for utilizing timing advance group synchronization information across multiple timing advance groups. Some embodiments provide support for performing random access procedures in relation to timing advance groups that may not include a primary component carrier. Some embodiments utilize timing advance group indexes to enable cross-carrier random access procedure management. Other embodiments support parallel random access procedures across multiple timing advance groups. Some embodiments provide for a reference downlink component carrier for timing within a timing advance group.

    摘要: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.
