Uplink buffer status reporting of relay stations in wireless networks

摘要

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.

1. A method comprising:
monitoring using one or more processors, an uplink buffer of a relay station communicating with a base station, wherein the uplink buffer comprises data to be transmitted from one or more user terminals to the base station; sending using the one or more processors,an uplink buffer status report from the relay station to the base station, the uplink buffer status report comprises occupancy status information of the monitored uplink buffer and a number of user terminals having data pending at the relay station for transmission to the base station; and reserving, using the one or more processors, a given amount of uplink resources from the uplink buffer on the occupancy status information, wherein the given amount of uplink resources is configured to optimize a current load of the uplink buffer when transmitting the data pending, wherein based on the occupancy status of the uplink buffer, the relay station decides for the base station either to schedule the user terminals to send more data or not without the BS knowing how many user terminals are currently coupled to the relay station.
