ENHANCED SCHEDULING IN WIRELESS NETWORKS WITH RELAY FUNCTION

Abstract

In cellular or other wireless networks, relay terminal devices can be introduced to support indirect network connections for remote terminal devices in out-of-coverage (OoC) areas to, thus, increase network coverage. Such relay terminal devices buffer upstream and downstream data from / to other indirectly connected terminal devices. However, relay terminal devices may have limited memory allocation for buffering. This limitation has a high impact on optimal resource scheduling performed by network access devices. Thus, it is proposed to have relay terminal devices report information regarding their maximum or available buffer capacity for their respective network access devices to enable optimal resource scheduling by the access devices.
