Abstract
Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.
Claims34
A method comprising:
- determining resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers;
- sending information indicative of the at least one component carrier and associated resources for configuration of a station for reference signalling;
- sending a trigger for reference signalling;
- and
- in response to the trigger, receiving at least one reference signal from the station on the indicated at least one component carrier, wherein the indicated at least one component carrier is determined by analyzing predefined bits of the information according to a pre-established protocol,
- wherein indication of the at least one component carrier and the trigger are communicated in the same message,
- and further comprising:
- determining that the message is only for assigning resources for signalling of aperiodic channel state information;
- checking the state of the trigger for reference signaling;
- determining, based on the message, that only reference signalling is to be transmitted;
- and
- determining at least one component carrier for reference signalling based on analysis of a predefined field of the message.
