Abstract
A user equipment UE receives (302) from a serving cell indications of frequency bands supported by neighbor cells/frequencies, at least one individual neighbor cell/frequency supporting a plurality of frequency bands. The neighbor cells/frequencies are filtered (304) to retain only those that are indicated to support a frequency band or frequency bands which are also supported by the UE. Examples are given of various system information blocks for sending the frequency band indications to the UE. In one embodiment (310), they are arranged in an information element IE having an entry for each of the neighbor cells/frequencies and a list of frequency bands for each entry. In another (312), the IE has an index and an associated frequency band(s) where a value of the index indicates that one or more of the neighbor cells/frequencies referred to by the index belongs to the associated frequency band(s).
