A signal measurement method performed by a user equipment, UE, the method comprising: • receiving (Sioi) a measurement configuration message from a base station of a serving cell; and being characterized by further comprising: • determining a field length of the received measurement configuration message; • in case the field length of the received measurement configuration message is equal to 10 bits: ∘ determining to measure a reference signal received power, RSRP, or to measure a reference signal received quality, RSRQ, in the serving cell or in a neighboring cell neighboring the serving cell based on a common reference signal, CRS; ∘ performing the RSRP measurement or the RSRQ measurement based on the CRS, thereby determining a first measurement result; • in case the field length of the received measurement configuration message is 12 bits, ∘ determining that the measurement configuration message includes a field used to indicate a reference signal type, wherein the field is formed by the rear two bits of the 12 bits; ∘ determining, according to a value of the field, which reference signal type is to be used for the RSRP or the RSRQ; ∘ performing, according to the reference signal type indicated by the measurement configuration message, the RSRP or the RSRQ measurement in the serving cell or in the neighboring cell, thereby determining a second measurement result; • sending the first measurement result or the second measurement result to the base station. • receiving (Sioi) a measurement configuration message from a base station of a serving cell; and being characterized by further comprising: • determining a field length of the received measurement configuration message; • in case the field length of the received measurement configuration message is equal to 10 bits: ∘ determining to measure a reference signal received power, RSRP, or to measure a reference signal received quality, RSRQ, in the serving cell or in a neighboring cell neighboring the serving cell based on a common reference signal, CRS; ∘ performing the RSRP measurement or the RSRQ measurement based on the CRS, thereby determining a first measurement result; ∘ determining to measure a reference signal received power, RSRP, or to measure a reference signal received quality, RSRQ, in the serving cell or in a neighboring cell neighboring the serving cell based on a common reference signal, CRS; ∘ performing the RSRP measurement or the RSRQ measurement based on the CRS, thereby determining a first measurement result; • in case the field length of the received measurement configuration message is 12 bits, ∘ determining that the measurement configuration message includes a field used to indicate a reference signal type, wherein the field is formed by the rear two bits of the 12 bits; ∘ determining, according to a value of the field, which reference signal type is to be used for the RSRP or the RSRQ; ∘ performing, according to the reference signal type indicated by the measurement configuration message, the RSRP or the RSRQ measurement in the serving cell or in the neighboring cell, thereby determining a second measurement result; ∘ determining that the measurement configuration message includes a field used to indicate a reference signal type, wherein the field is formed by the rear two bits of the 12 bits; ∘ determining, according to a value of the field, which reference signal type is to be used for the RSRP or the RSRQ; ∘ performing, according to the reference signal type indicated by the measurement configuration message, the RSRP or the RSRQ measurement in the serving cell or in the neighboring cell, thereby determining a second measurement result; • sending the first measurement result or the second measurement result to the base station.
