MULTI-USER DETECTOR AND METHOD FOR USE IN A COMMUNICATION SYSTEM

A multi-user detector (200) and method (300) for use in a cellular CDMA system (100) based on: estimating (210) spare code resource available in a first cell of the system; selecting (220) at least a second cell neighbouring the first cell; selecting (230) from codes associated with the second cell...

description	A multi-user detector (200) and method (300) for use in a cellular CDMA system (100) based on: estimating (210) spare code resource available in a first cell of the system; selecting (220) at least a second cell neighbouring the first cell; selecting (230) from codes associated with the second cell at least one additional code; and performing (240) multi-user detection processing in the first cell with the at least one additional code. On the downlink, codes from other users in the same cell may be treated with the same level of priority as those of users from neighbour cells, codes allocated to the UE having the highest priority; on the uplink, codes of all users in the same cell may have the same priority which is higher than that of neighbour cell users. This provides the advantage(s) that multi-user detector capacity arising from operating under high interference conditions is employed to accommodate users from neighbour cells, with the result that both intracell and intercell interference may be mitigated.
