Abstract:
Adaptation of measurement procedures for cell detection and association provide more accurate and frequent reports for use by the network, to enhance cell association. A user equipment receives, within a configured measurement bandwidth, orthogonal frequency division multiplexing symbols comprising discovery reference signals (DRS). For subframes in which the DRS are transmitted, a discovery reference signal received quality (D-RSRQ) is determined from the DRS within the received symbols as a ratio of discovery reference signal received power (D-RSRP) to carrier discovery received signal strength indicator (D-RSSI), where the D-RSRP is measured in symbols containing DRS resource elements and the D-RSSI is measured in all symbols in subframes containing the DRS. For a UE configured to also measure common reference signals, non-DRS measurements are suspended upon deactivation of a secondary cell, and measurement timing of the DRS during a deactivation period is based on a measurement timing parameter.
