Abstract
Methods and apparatus, including computer program products, are provided for controlling measurements and, in particular, a type of load-sensitive measurement, such as received signal, received quality (RSRQ), performed by a user equipment. Related apparatus, systems, methods, and articles are also described.
Claims19
A method comprising:
- receiving, at a user equipment and from a base station, an indicator representative of whether a first type of reference signal received quality measurement or a second type of reference signal received quality measurement is to be used for reference signal received quality measurements;
- measuring, by the user equipment and in response to the indicator indicating the first type of reference signal received quality measurement associated with an offloading cell, over all orthogonal frequency division multiplexing symbols included in a bandwidth of a subframe to determine the first type of reference signal received quality measurement, the bandwidth including all the orthogonal frequency division multiplexing symbols including first symbols with a reference signal and second symbols without the reference signal;
- measuring, by the user equipment and in response to the indicator indicating the second type of reference signal received quality measurement, over a subset of all the orthogonal frequency division multiplexing symbols included in the bandwidth of the subframe to determine the second type of reference signal received quality measurement, the subset comprising only the first symbols with the reference signal;
- and
- reporting, by the user equipment and to the base station, information indicative of the first type or the second type of reference signal received quality measurement.

An apparatus comprising:
- at least one processor circuitry;
- and
- at least one memory circuitry including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
- receive, from a base station, an indicator representative of whether a first type reference signal received quality measurement or a second type of reference signal received quality measurement is to be used for reference signal received quality measurements;
- measure, when the indicator indicates the first type of reference signal received quality measurement associated with an offloading cell, over all orthogonal frequency division multiplexing symbols included in a bandwidth of a subframe to determine the first type of reference signal received quality measurement, the bandwidth including all the orthogonal frequency division multiplexing symbols including first symbols with a reference signal and second symbols without the reference signal;
- measure, when the indicator indicates the second type of reference signal received quality measurement, over a subset of all the orthogonal frequency division multiplexing symbols included in the bandwidth of the subframe to determine the second type of reference signal received quality measurement, the subset comprising the first symbols with the only reference signal;
- and
- report, to the base station, information indicative of the first type or the second type of reference signal received quality measurement.

A non-transitory computer-readable medium comprising instructions which, when executed by at least one processor circuitry, result in operations comprising:
- receiving, at a user equipment and from a base station, an indicator representative of whether a first type of reference signal received quality measurement or a second type of reference signal received quality measurement is to be used for reference signal received quality measurements;
- measuring, by the user equipment and in response to the indicator indicating the first type of reference signal received quality measurement associated with an offloading cell, over all orthogonal frequency division multiplexing symbols included in a bandwidth of a subframe to determine the first type of reference signal received quality measurement, the bandwidth including all the orthogonal frequency division multiplexing symbols including first symbols with a reference signal and second symbols without the reference signal;
- measuring, by the user equipment and in response to the indicator indicating the second type of reference signal received quality measurement, over a subset of all the orthogonal frequency division multiplexing symbols included in the bandwidth of the subframe to determine the second type of reference signal received quality measurement, the subset comprising only the first symbols with the reference signal;
- and
- reporting, by the user equipment and to the base station, information indicative of the first type or the second type of reference signal received quality measurement.
