Abstract

A system is disclosed in which a communication device provides measurement reports to a communication network. The communication device connects to a cell of the network and receives configuration data for at least one relay specific trigger event for triggering measurement reporting for at least one relay cell operated by a relay device for the base station. The communication device performs measurements and sends a measurement report to the communication network when the trigger event has occurred.

First claim

1 - 41 . (canceled)

42 . A communication device for providing measurement reports, the communication device comprising a controller and a transceiver, wherein the controller is configured to:
control the transceiver to receive a measurement configuration information element comprising configuration information; wherein the configuration information specifies criteria for triggering of measurement reporting, wherein the configuration information is configurable to specify any of a plurality of different trigger types for measurement reporting, the trigger types comprising a periodical trigger type and an event trigger type, wherein the configuration information is configurable, when the trigger type is set to event, to further specify any of a plurality of possible trigger events including a plurality of type A trigger events, a plurality of type B trigger events, and at least one further trigger event that is different to said type A and type B trigger events for triggering measurement reporting for measurements of channel state reference signals (CSI-RS), perform measurements based on the configuration data; and initiate a measurement reporting procedure when the trigger type is specified to be an event type trigger, when the trigger event is specified to be the at least one further trigger event that is different to said type A and type B trigger events, and when a condition applicable for the specified trigger event is fulfilled for said measurements.

43 . The communication device according to claim 42 wherein the at least one further trigger event for triggering measurement reporting that is different to said type A and type B trigger events is characterised by an entering condition that is met when a measurement result for the CSI-RS, plus an offset value, and minus a hysteresis value exceeds a predetermined value.

44 . The communication device according to claim 42 wherein the at least one further trigger event for triggering measurement reporting that is different to said type A and type B trigger events is characterised by a leaving condition that is met when a measurement result for the CSI-RS, plus an offset value, and plus a hysteresis value is less than the predetermined value.

45 . The communication device according to claim 43 , wherein the predetermined value comprises a threshold value provided in said configuration information.

46 . The communication device according to claim 44 , wherein comprises a threshold value provided in said configuration information.

47 . The communication device according to claim 43 , wherein said configuration information defines said hysteresis value.

48 . The communication device according to claim 44 , wherein said configuration information defines said hysteresis value.

49 . A method performed by a communication device for providing measurement reports, the method comprising:
receiving a measurement configuration information element comprising configuration information; wherein the configuration information specifies criteria for triggering of measurement reporting, wherein the configuration information is configurable to specify any of a plurality of different trigger types for measurement reporting, the trigger types comprising a periodical trigger type and an event trigger type, wherein the configuration information is configurable, when the trigger type is set to event, to further specify any of a plurality of possible trigger events including a plurality of type A trigger events, a plurality of type B trigger events, and at least one further trigger event that is different to said type A and type B trigger events for triggering measurement reporting for measurements of channel state reference signals (CSI-RS), performing measurements based on the configuration data; and initiating a measurement reporting procedure when the trigger type is specified to be an event type trigger, when the trigger event is specified to be the at least one further trigger event that is different to said type A and type B trigger events, and when a condition applicable for the specified trigger event is fulfilled for said measurements.
