A user equipment (2) has an ability to operate according to one or more spectrum emission requirement capability values (14) in a wireless communications network having at least a first serving cell (4). A message (6) is received. at the user equipment (2) from the first serving cell (4) comprising a first indicator representing a first band designation (8), a second indicator representing a spectrum emission requirement value (10), and. at least one additional indicator representing at least one additional spectrum emission requirement value (12), both the first and. additional indicators relating to the First band designation_ The user equipment (2) performs a comparison of the first and. additional spectnun emission requirement values (10, 12) with the one or more spectrum emission requirement capability values (14) and determines a behaviour of the user equipment (2) 'in relation to the first serving cell (4) in dependence on the comparison. The capability values may be of different stringency, allowing a small number of roaming equipment to operate in a system even if they do not meet a first, less stringent requirement. |
