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.

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： A method for accessing a hybrid network including a wide area network and a distributed network, a gateway apparatus, a wireless terminal and a gateway communication system are disclosed for reducing the power consumption of the wireless terminal which is an access gateway. The method comprises: sensing by a gateway apparatus a relay request slot on a downlink common control channel of the wide area network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, in the relay request slot on the downlink common control channel; and if the relay request signal from the wireless terminal is sensed in the relay request slot, establishing by the gateway apparatus a connection with the wireless terminal in a distributed network environment. As such, the gateway apparatus accesses the wireless distributed network only when the surrounding wireless terminals require data relay, without sensing signals on both networks simultaneously, in order to reduce the power consumption.
