A solution for radio access in a code division multiple access (CDMA)-based telecommunication system, in which orthogonal spreading codes are used for separating data of a plurality of user entities, is provided. According to the solution, a different pilot symbol sequence is allocated to each user entity, and the pilot symbol sequences of user entities are selected by allocating different frequencies for pilot symbol sequences of different user entities according to a frequency division multiple access (FDMA) technique in order to mitigate the effect of multiple access interference.
