TRANSMISSION OF MEASUREMENT REPORTS IN A WIRELESS COMMUNICATION SYSTEM

摘要

A wireless telecommunications system including a base station and terminal device, supporting a virtual carrier mode with downlink communications made by the base station using a radio interface spanning a system frequency bandwidth while the terminal device can receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth providing a restricted bandwidth downlink. The terminal device can measure channel conditions across the system frequency bandwidth and transmit corresponding measurement reports to the base station. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be aperiodic while measurement reports for transmission resources including the restricted bandwidth downlink channel may be periodic. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be based on a subset of the channel condition measurements selected because they are associated with relatively poor channel conditions.

1. A method of operating a terminal device in a wireless telecommunications system in which downlink communications are made by a base station using a radio interface that spans a system frequency bandwidth and the terminal device is configured to receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth and comprising a restricted bandwidth downlink channel having a channel bandwidth which is smaller than the system frequency bandwidth, the method comprising:
measuring channel conditions across the system frequency bandwidth; and transmitting to the base station channel condition measurement reports for a plurality of frequencies across the system frequency bandwidth, wherein a resolution of the measurement reports for transmission resources not comprising the restricted bandwidth downlink channel is less than a resolution of the measurement reports for transmission resources comprising the restricted bandwidth downlink channel.
