A method and apparatus for testing point-to-multipoint services and other
wireless communication services dependent on unidirectional radio bearers
and/or unacknowledged mode operations is described herein. A wireless
communication device activates a test module responsive to receiving a
test activation message. During a test mode, the test module receives RLC
data units from a test system via a unidirectional downlink radio bearer
or a control channel. In one embodiment, the test module includes a
metric evaluator that determines an error metric based on the received
RLC data units. The test module reports the error metric to the test
system. In another embodiment, the test module includes a loop-back
module that loops-back at least a portion of the received RLC data units
to the test system via a unidirectional uplink radio bearer.
