Abstract
Cells from which to receive information transmitted on a traffic channel that is not subject to power control in a cellular radio communications system are selected. Selection involves, for each of a plurality of candidate cells, using an offset value that indicates a relationship between a pilot channel transmission power and the traffic channel transmission power associated with the candidate cell to determine a value of quality indicative of power of a signal transmitted on the traffic channel associated with the candidate cell; and selecting, based on the values of quality indicative of power of a signal transmitted on the traffic channel, a number, N, of cells from the plurality of candidate cells.
Claims26
A method of selecting one or more cells from which to receive information transmitted on a traffic channel that is not subject to power control in a cellular radio communications system, the method comprising:
- for each of a plurality of candidate cells, using an offset value that indicates a relationship between a pilot channel transmission power and the traffic channel transmission power associated with the candidate cell to determine a value of quality indicative of power of a signal transmitted on the traffic channel associated with the candidate cell;
- and
- selecting, based on the values of quality indicative of power of a signal transmitted on the traffic channel, a number, N, of cells from the plurality of candidate cells.
An apparatus for selecting one or more cells from which to receive information transmitted on a traffic channel that is not subject to power control in a cellular radio communications system, the apparatus comprising:
- logic configured to, for each of a plurality of candidate cells, use an offset value that indicates a relationship between a pilot channel transmission power and the traffic channel transmission power associated with the candidate cell to determine a value of quality indicative of power of a signal transmitted on the traffic channel associated with the candidate cell;
- and
- logic configured to select, based on the values of quality indicative of power of a signal transmitted on the traffic channel, a number, N, of cells from the plurality of candidate cells.
