Abstract
A method for determining whether a connection event between a base station and a wireless transmit/receive unit (WTRU) should be accepted or rejected, comprises measuring the interference level I0 in a candidate timeslot; measuring the path loss L between the base station and the WTRU; measuring the total transmit power P0 of the base station; determining a thermal noise level θ; determining a fading average signal-to-interference ratio (SIR); and calculating a ratio R, wherein if the ratio R is above a certain threshold the connection event will be accepted and if the call is below the threshold it will be rejected.
Claims4
A base station for wireless communications comprising:
- a processor configured to determine a total transmission power P0 and reporting the total transmission power to a Radio Network Controller (RNC);
- a controller configured to determine whether a connection with a wireless transmit receive unit (WTRU) is to be added or deleted;
- and
- on a condition that a connection is to be added, adding a connection between with the WTRU on the condition that a predicted interference level does not exceed a predetermined maximum value, using measurements from the WTRU.
