Abstract
A method for allocating orthogonal codes, whereby the product of a number of active users in the system and the average number of sectors servicing each user is determined, and sufficient orthogonal codes are allocated to service the product of F and the optimal number of active users in the system. At least one message is transmitted for reception by at least one mobile station, the message indicating the number of allocated orthogonal codes.
Claims27
A method for allocating orthogonal codes to users of mobile stations in a telecommunication system, the method comprising:
- determining an effective number of mobile station users equal to the product of a number of active users in the system and a value relating to F, wherein F represents the average number of sectors that a mobile station may obtain service from concurrently;
- allocating sufficient orthogonal codes to service the effective number of users;
- and transmitting for reception by at least one mobile station at least one message indicating the number of allocated orthogonal codes.
A base station configured for allocating orthogonal codes, the base station comprising:
- means for determining an effective number of users equal to the product of a number of active users in a system and a value relating to F, wherein F represents the average number of sectors that a mobile station may obtain service from concurrently;
- means for allocating sufficient orthogonal codes to service the effective number of users;
- and
- means for transmitting for reception by at least one mobile station at least one message indicating the number of allocated orthogonal codes.
A telecommunications system utilizing a computer program product having a medium with a computer program code for allocating orthogonal codes embodied thereon, the telecommunications system comprising:
- a digital processor for executing the computer program code stored on the medium for determining an effective number users equal to the product of a number of active users in the telecommunications system, and a value relating to F, wherein F represents the average number of sectors that a mobile station may obtain service from concurrently;
- allocating sufficient orthogonal codes to service the effective number of users;
- and
- transmitting one or more messages indicating the number of allocated orthogonal codes to one or more mobile stations from a base station.
