Abstract

According to some embodiments, a method performed by a wireless device includes monitoring a set of two or more strongest beams over a predefined time period, and based on an amount of change in the set of two or more strongest beams over the predefined time period, determining whether the wireless device is stationary or low-mobility. The method may further include relaxing a radio resource management (RRM) measurement configuration.

Claims (36)

1 . A method performed by a wireless device, the method comprising:

monitoring a set of two or more strongest beams over a predefined time period; and

based on an amount of change in the set of two or more strongest beams over the predefined time period,

determining whether the wireless device is stationary or low-mobility,

wherein the change in the set of two or more strongest beams referring to a change in the ordering of the strongest beams over the predetermined time period.

2 . The method of claim 1 , further comprising:

upon determining the wireless device is stationary or low-mobility, relaxing a radio resource management measurement configuration.

3 . The method of claim 1 , wherein the change in the set of two or more strongest beams refers to a change in the strongest beams over the predetermined time period.

4 . The method of claim 1 , wherein the change in the set of two or more strongest beams refers to a change in the signal strength of the strongest beams over the predetermined time period.

5 . The method of claim 1 , wherein the change in the set of two or more strongest beams refers to a change in antenna panels used by the wireless device over the predetermined time period.

6 . The method of claim 1 , wherein the wireless device comprises a reduced capacity wireless device.

7 . A wireless device comprising processing circuitry, the processing circuitry operable to:

monitor a set of two or more strongest beams over a predefined time period; and

based on an amount of change in the set of two or more strongest beams over the predefined time period,

determine whether the wireless device is stationary or low-mobility,

wherein the change in the set of two or more strongest beams referring to a change in the ordering of the strongest beams over the predetermined time period.

8 . The wireless device of claim 7 , the processing circuitry further operable to:

upon determining the wireless device is stationary or low-mobility, relax a radio resource management (RRM) measurement configuration.

9 . The wireless device of claim 7 , wherein the change in the set of two or more strongest beams refers to a change in the strongest beams over the predetermined time period.

10 . The wireless device of claim 7 , wherein the change in the set of two or more strongest beams refers to a change in the signal strength of the strongest beams over the predetermined time period.

11 . A method performed by a wireless device, the method comprising:

monitoring a set of two or more strongest neighbor cells over a predefined time period; and

based on an amount of change in the set of two or more strongest neighbor cells over the predefined time period,

determining whether the wireless device is stationary or low-mobility,

wherein the change in the set of two or more strongest neighbor cells referring to a change in the ordering of the strongest neighbor cells over the predetermined time period.

12 . The method of claim 11 , further comprising:

upon determining the wireless device is stationary or low-mobility, relaxing a radio resource management (RRM) measurement configuration.

13 . The method of claim 11 , wherein the change in the set of two or more strongest neighbor cells refers to a change in the strongest neighbor cells over the predetermined time period.

14 . The method of claim 11 , wherein the change in the set of two or more strongest neighbor cells refers to a change in the signal strength of the strongest neighbor cells over the predetermined time period.

15 . The method of claim 11 , wherein the change in the set of two or more strongest neighbor cells refers to a change in antenna panels used by the wireless device over the predetermined time period.

16 . The method of claim 11 , wherein the wireless device comprises a reduced capacity wireless device.

17 . A wireless device comprising processing circuitry, the processing circuitry operable to:

monitor a set of two or more strongest neighbor cells over a predefined time period; and

based on an amount of change in the set of two or more strongest neighbor cells over the predefined time period,

determine whether the wireless device is stationary or low-mobility,

wherein the change in the set of two or more strongest neighbor cells referring to a change in the ordering of the strongest neighbor cells over the predetermined time period.
