Claim:
1. A method implemented by a base station configured to serve a cell in a wireless communication system, the method comprising: determining, for each of one or more mobile terminals or downlink carriers in the cell, a preference for whether the length of a scrambling code to be allocated to that mobile terminal or carrier should be short or long, based on whether uplink communications transmitted by the mobile terminal, or downlink communications transmitted over the carrier, are to be processed with a high-complexity receiver or a low-complexity receiver, wherein a high-complexity receiver is a receiver that is classified by the base station as being of greater complexity than a low-complexity receiver, wherein determining a preference for whether the length of a scrambling code to be allocated to a mobile terminal or downlink carrier should be short or long is directly or indirectly based on whether uplink communications transmitted by the mobile terminal, or downlink communications transmitted over the carrier, are to be: sending control signaling indicating said preferences to a radio network controller that is configured to take those preferences into account in order to allocate either a short scrambling code or a long scrambling code to each mobile terminal or downlink carrier, wherein a short scrambling code is shorter in length than a long scrambling code.
