Description
Execution command returns received signal quality parameters. If the current serving cell is not a GERAN cell, <rxlev> and <ber> are set to value 99. If the current serving cell is not a UTRA FDD or UTRA TDD cell, <rscp> is set to 255. If the current serving cell is not a UTRA FDD cell, <ecno> is set to 255. If the current serving cell is not an E-UTRA cell, <rsrq> and <rsrp> are set to 255. If the current serving cell is not an NR cell, <ss_rsrq>, <ss_rsrp> and <ss_sinr> are set to 255.
Refer clause 9.2 for possible <err> values.
Test command returns values supported as compound values.
