Abstract
A mobile terminal in a wireless communications system estimates channel characteristics from transmissions of a base station comprising reference symbols arranged in a first density and distribution. In the event of an impairment in accuracy of channel estimation, the mobile terminal first applies a checking function to determine whether a base station identity conflict is present. If such a conflict is detected, it transmits a report to the base station to initiate a network channel reallocation process to remove the conflict. If no conflict is detected, the base station is instructed to initiate a function to change the density and distribution of the reference symbols. This allows a dynamic system to distinguish between different causes of poor channel quality, allowing adaptation of the transmissions of the base stations in a manner appropriate to the cause identified.
