Title: Method and apparatus for adjusting a reselection timer and cell ranking criteria, and reporting degraded signal measurement of a serving cell
Inventor: SOMASUNDARAM SHANKAR
IPC: H04W36/32
Filed: 2008-03-05
Abstract: Various methods for adjusting a reselection timer and cell ranking criteria are disclosed. The ranking criteria of a serving or neighbor cell, or a reselection timer in a wireless transmit/receive unit (WTRU), is adjusted based on how a serving cell signal measurement, (e.g., signal strength, signal quality), compares to a plurality of thresholds over a time interval. In another method, cell ranking criteria is adjusted based on a hysteresis value and a scaling factor when a maximum number of reselections is exceeded and a high mobility factor is detected. Furthermore, a method of reporting cell signal measurements is disclosed, whereby a time-to-trigger time (TTT) interval is started when the neighbor cell signal measurement rises above a reporting range threshold. If the serving cell signal measurement falls below a serving cell threshold, the TTT interval is adjusted and thereby a measurement report is transmitted during the TTT interval.
