## Abstract

Methods performed by base stations and wireless devices for reducing RSRP and/or RSRQ measurements are disclosed. A method performed by a base station comprises indicating to a wireless device whether or not to perform cell selection and/or reselection measurements based on certain criteria. A method performed by a wireless device comprises determining whether or not to perform cell selection and/or reselection measurements based on certain criteria. Also disclosed are base stations and wireless devices configured to perform the methods.

## Claims

### Claim 1

A method performed by a wireless device for reducing Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) measurements, the method comprising:
determining, based on certain criteria indicating one or more non-measurement zones, that a measurement condition is satisfied; and
as a result of determining that the measurement condition is satisfied, refraining from performing a cell selection or reselection measurement for at least a first cell, wherein
the first cell is a spotbeam generated by a satellite, wherein
determining that the measurement condition is satisfied comprises determining that a geographical position of the wireless device is within one of the one or more non-measurement zones.

### Claim 2 (depends on 1)

The method of claim 1, wherein the one or more non-measurement zones are defined using one or more reference locations.

### Claim 3 (depends on 2)

The method of claim 2, wherein the one or more reference locations are earth fixed.

### Claim 4 (depends on 2)

The method of claim 2, wherein the one or more reference locations change with time.

### Claim 5 (depends on 2)

The method of claim 2, wherein the reference locations are defined relative to a satellite position.

### Claim 6 (depends on 2)

The method of claim 2, wherein the reference locations are defined relative to the satellite spotbeam.

### Claim 7 (depends on 2)

The method of claim 2, wherein the criteria comprise one or more intra-frequency measurement rules and/or one or more inter-frequency measurement rules.

### Claim 8 (depends on 7)

The method of claim 7, wherein the criteria comprise a geographical distance between the wireless device and a cell, and wherein the intra-frequency measurement rule and/or intra-frequency measurement rule to be applied to a given cell is dependent upon the geographical distance between the wireless device and the given cell.

### Claim 9 (depends on 8)

The method of claim 8, wherein different thresholds are used to determine whether or not RSRP and/or RSRQ measurements should be performed for the given cell, based on the geographical distance between the wireless device and the given cell.

### Claim 10 (depends on 1)

The method of claim 1, wherein the criteria comprise a list of cells identified by a wireless network.

### Claim 11 (depends on 10)

The method of claim 10, wherein a set of cells are selected for RSRP and/or RSRQ measurement activity, and the cells in the set of cells are close in geographical distance to the wireless device.

### Claim 12 (depends on 1)

The method of claim 1, wherein the criteria are indicated by one or more of the following:
a Radio Resource Control message;
a Medium Access Control Control Element;
a Radio Network Temporary Identifier;
Downlink Control Information; or
a Non-Access Stratum message.

### Claim 13 (depends on 1)

The method of claim 1, wherein the wireless device performs measurements to obtain the geographical position of the wireless device.

### Claim 14 (depends on 13)

The method of claim 13, wherein the geographical measurements use Global Navigation Satellite System signals.

### Claim 15 (depends on 1)

The method of claim 1, wherein the satellite is a Low Earth Orbit satellite, a Middle Earth Orbit satellite, or a Geostationary Orbit satellite.

### Claim 16 (depends on 1)

The method of claim 1, further comprising:
providing user data; and
forwarding the user data to a host computer via a transmission to a base station.

### Claim 17

A method for reducing Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) measurements, the method comprising:
a base station indicating to a wireless device whether or not to perform cell selection and/or reselection measurements based on certain criteria,
wherein at least one of the cells for which the wireless device may perform cell selection or reselection measurements is a spotbeam generated by a satellite, wherein
the criteria comprise one or more intra-frequency measurement rules and/or one or more inter-frequency measurement rules, and
the criteria comprise a geographical distance between the wireless device and a cell, and wherein the intra-frequency measurement rule and/or intra-frequency measurement rule to be applied to a given cell is dependent upon the geographical distance between the wireless device and the given cell.

### Claim 18 (depends on 17)

The method of claim 17, wherein the criteria comprises one or more non-measurement zones configured by the base station.

### Claim 19 (depends on 18)

The method of claim 18, wherein

iii) the one or more reference locations are defined relative to a satellite position, or
iv) the reference locations are defined relative to the spotbeam.

### Claim 20 (depends on 17)

The method of claim 17, wherein different thresholds are used to determine whether or not RSRP and/or RSRQ measurements should be performed for the given cell, based on the geographical distance between the wireless device and the given cell.

### Claim 21 (depends on 17)

The method of claim 17, wherein
the criteria comprise a list of cells identified by the base station,
a set of cells are selected for RSRP and/or RSRQ measurements, and
the cells in the set of cells are close in geographical distance to the wireless device.

### Claim 22

A wireless device for reducing Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) measurements, the wireless device comprising:
processing circuitry; and
power supply circuitry configured to supply power to the wireless device, wherein the processing circuitry is configured to cause the wireless device to perform a method comprising:
determining, based on certain criteria indicating one or more non-measurement zones, that a measurement condition is satisfied; and
as a result of determining that the measurement condition is satisfied, refraining from performing a cell selection or reselection measurement for at least a first cell, wherein
the first cell is a spotbeam generated by a satellite, and
determining that the measurement condition is satisfied comprises determining that a geographical position of the wireless device is within one of the one or more non-measurement zones.
