  • Method and apparatus for communicating delivery of data packets to a user equipment in a wireless communication system
    Patent number: 9572072
    Abstract: In a communication system (100) where a wireless relay node (RN) (114) relays data packets between a Node B (112) and a user equipment (UE) (102), the RN receives (608) a data packet from the Node B via a first wireless link (115), conveys (614) the received data packet to the UE via a second wireless link (120), determines (616) whether the UE is likely to handoff, and in response to determining that the UE is likely to handoff, delays conveying (620, 622) an acknowledgment of the data packet to the Node B until an acknowledgment has been received from the UE. In another embodiment, the RN may use a status report (720) to inform the Node B of data packets that have not been transmitted to the UE or that have been transmitted to the UE but for which an acknowledgement has not been received from the UE.

  • Uplink buffer status reporting of relay stations in wireless networks
    Patent number: 9160662
    Abstract: The present disclosure is directed to a method for reporting uplink buffer status of a relay station to a base station in a wireless network. The method includes monitoring an uplink buffer of the relay station communicating with the base station, where the uplink buffer comprises data to be transmitted from one or more user terminals to the base station. The method further includes sending an uplink buffer status report from the relay station to the base station, where the uplink buffer status report includes occupancy status information of the monitored uplink buffer and a number of user terminals having data queued up at the relay station to be transmitted to the base station.
