In the
UMTS cellular communication system, received signal code power (RSCP) denotes the
power measured by a
receiver on a particular physical communication channel. It is used as an indication of
signal strength
In telecommunications, particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those us ...
, as a
handover criterion, in downlink
power control, and to calculate
path loss. In
CDMA systems, a physical channel corresponds to a particular
spreading code, hence the name (Received signal code power). RSCP is also called Receiver Side Call Power.
While RSCP can be defined generally for any CDMA system, it is more specifically used in UMTS. Also, while RSCP can be measured in principle on the
downlink as well as on the
uplink, it is only defined for the downlink and thus presumed to be measured by the
UE and reported to the
Node B.
