Stands for
Reference Signal Received Quality
Defined in

Used in

In plain words

The TR 21.905 vocabulary entry expands RSRQ as Reference Signal Received Quality, while TS 36.214 clause 5.1.3 gives an RSRQ measurement rule. "If higher layers indicate all OFDM symbols for performing RSRQ measurements, then RSSI is measured from all OFDM symbols of the DL part of measurement subframes." TS 25.215 and TS 25.225 clauses 5.1.19 cover E-UTRA RSRQ, and both give the same RSSI rule.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
