SS-RSRQ SS reference signal received quality

SS-RSRQ stands for Serving Cell Reference Signal Received Quality. It is a parameter used in Long Term Evolution (LTE) and 5G wireless networks to measure the quality of the reference signals received from the serving cell. RSRQ stands for Reference Signal Received Quality, which is a more general term used to evaluate the quality of reference signals in a wireless network.

In LTE and 5G systems, reference signals are periodically transmitted by the base station (eNodeB in LTE, gNodeB in 5G) to allow the mobile devices (User Equipment) to estimate the channel conditions and perform various network measurements. These reference signals carry important information that helps the UE in determining the signal strength and quality of the serving cell, as well as neighboring cells.

SS-RSRQ specifically measures the quality of the serving cell reference signals. It is calculated by taking the ratio of the received power of the reference signals to the total received power, including the serving cell and interference from neighboring cells. The formula for SS-RSRQ is:

SS-RSRQ = (RSRP_serving_cell) / (RSRQ_interference + RSRQ_serving_cell)

Here, RSRP (Reference Signal Received Power) represents the received power of the serving cell, and RSRQ (Reference Signal Received Quality) represents the received power of the interfering cells.

RSRP is a measure of the signal strength of the serving cell, while RSRQ takes into account both the signal strength and the interference from neighboring cells. It provides an indication of the quality of the received signals in relation to the interference level.

SS-RSRQ is typically reported by the UE to the network for various purposes, such as handover decisions, cell selection, and resource allocation. A higher SS-RSRQ value indicates a stronger serving cell signal with lower interference, which is desirable for maintaining a stable and reliable connection. Conversely, a lower SS-RSRQ value suggests a weaker serving cell signal or higher interference, which may lead to degraded network performance or connectivity issues.

Network operators and engineers monitor SS-RSRQ values to assess the overall quality of the wireless network and make necessary adjustments to optimize network performance, coverage, and capacity.

In summary, SS-RSRQ (Serving Cell Reference Signal Received Quality) is a parameter used in LTE and 5G networks to measure the quality of reference signals received from the serving cell. It considers both the signal strength of the serving cell and the interference from neighboring cells, providing valuable information for network optimization and decision-making processes.
