Abstract
In a method and a system a good spread of users per code is obtained by providing a value related to the current load for each code in the system. The estimated load value can be used by the network to assign the HS-PDSCH code for users in HS-SCCH less operation, and may also be used in the dynamic transmission process, i.e. which codes are to be used by which user during this and future TTIs. If one code is over a given utilization threshold, where the threshold is set in order to avoid code blocking of VoIP users, enough users can be re-assigned to a different code. In the case that all of the current codes used in the HS-SCCH less operation model are over the utilization threshold, yet another code can be made available for HS-SCCH less operation.

17. A method of assigning codes for users in a cellular radio system operating in a High Speed Shared Control Channel (HS-SCCH) less mode of operation, the method comprising:
-
determining the system load generated by a user communicating with the system in a HS-SCCH less operation mode; and assigning a code for the user in response to said determined system load. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
