HSPA, located at the edge of the cell generally suffer from poor
channel conditions. Deploying intermediate relay nodes is seen
as a promising approach towards extending cell coverage and
increasing data rates. This paper focuses on the role of packet
scheduling in cellular networks with relay nodes. In particular,
two uplink scheduling schemes deploying the relay functionality
in different ways are compared in performance to a reference
scenario where relaying is not used. We derive expressions which
characterize for each of the two relay-enabled schedulers the
service area of a relay station as a function of the relay location
and transmit power. The results show that the service area is
significantly influenced by the type of scheduling. Examining
the impact on the effective data rates of mobile stations shows
that there is a combination of the relay’s position and transmit
power which optimizes uplink service. Furthermore, based on
calculations of flow throughput, we show that relaying improves
flow level performance of all users, including those who do not
use the relay. | Item Type: | Conference or Workshop Paper (Full Paper, Talk) |
