摘要： A buffer information report can be sent to a system station from a node for relaying communications between at least one user station and the system station. The report is generated based on a report format used for uplink reporting by a user station. An indication is also sent to the system station that the node for relaying has different buffering capabilities than the user station. At the system station the buffering capabilities of the node for relaying can be determined based on the buffer information report and the indication. Communications between the system station and the node for relaying can then be controlled accordingly.

摘要： Methods and apparatuses for controlling a handover of a device communicating via coexisting radios separated in time. It is determined whether to continue the communications via the coexisting radios during the handover and information is signaled to the device regarding communications via the coexisting radios based on the determination. The determination can include negotiations between a source and a target station. The source and/or the target station may determine whether to continue the communications via the coexisting radios during the handover, and selectively signaling information regarding communications during the handover via the coexisting radios based on the determination. The device, upon receiving signaling containing information whether to continue the communications via the coexisting radios during handover, processes the handover and selectively communicates via at least one of the coexisting radios during the handover based on the information.
