Feedback messaging

摘要

The disclosure relates to methods and apparatuses for feedback messaging in a communication system. A station can include into a scheduling information entity an indication of aperiodic feedback messaging on a physical uplink control channel and dynamically send the scheduling information entity with the indication to a communication device configured for periodic feedback messaging to trigger aperiodic feedback messaging by the communication device on the physical uplink control channel. Upon receiving the scheduling information entity the device can determine that it includes the indication and in response to the determining send at least one aperiodic feedback message on the physical uplink control channel.

1. A method comprising:
determining a need to trigger aperiodic feedback messaging on a physical uplink control channel from a communication device configured for periodic feedback messaging; including in a scheduling information entity an indication to provide aperiodic feedback messaging on the physical uplink control channel; sending the scheduling information entity with the indication to the communication device to trigger the aperiodic feedback messaging by the communication device on the physical uplink control channel; dynamically controlling content of the aperiodic feedback messaging with the sent indication, wherein the controlling causes the communication device to send feedback information content in the aperiodic feedback messaging different from that reserved for use in a preconfigured manner in the periodic feedback messaging, whereby the need for a separate uplink grant message on a physical downlink control channel to trigger the aperiodic feedback messaging on the physical uplink control channel is avoided.
