The method includes: obtaining a channel hardening (CH) parameter; changing a measurement parameter based on the obtained CH parameter; and adapting a measurement procedure in accordance with the changed parameter. A method performed by a network node, the method includes obtaining a channel hardening (CH) parameter corresponding to a user equipment (UE); and sending to the UE an indication that the UE is allowed to perform optimizations based on the obtained CH parameter. ## Claims ### Claim 1 A method, performed by a user equipment (UE), the method comprising: obtaining an indication that a channel hardening (CH) condition is present; based on the indication that the CH condition is present, obtaining a CH parameter; determining that the obtained CH parameter is less than a first CH threshold; in response to determining that the obtained CH parameter is less than the first CH threshold, changing a measurement parameter based on the obtained CH parameter; and adapting a measurement procedure in accordance with the changed measurement parameter. ### Claim 2 (depends on 1) The method of claim 1, wherein the measurement procedure is a radio resource management (RRM) measurement which involves measuring a quantity including one or more of a channel quality indicator (COI), a reference signal received power (RSRP), a reference signal received quality (RSRQ), and a carrier received signal strength indicator (RSSI). ### Claim 3 (depends on 1) The method of claim 1, wherein the measurement parameter is selected from the group consisting of a measurement period, a sample length, a length of coherent averaging, a measurement bandwidth, a set of reference signals, and a number of beams to average. ### Claim 4 (depends on 1) The method of claim 1, further comprising, as a result of obtaining the indication that the CH condition is present, periodically changing the measurement parameter based on the obtained CH parameter. ### Claim 5 (depends on 4) The method of claim 4, further comprising determining that the CH condition is not present and, as a result of determining that the CH condition is not present, ceasing to periodically change the measurement parameter based on the obtained CH parameter. ### Claim 6 (depends on 1) The method of claim 1, wherein changing a measurement parameter based on the obtained CH parameter comprises determining that a CH condition is not present and as a result of the CH condition not being present, changing the measurement parameter. ### Claim 7 (depends on 6) The method of claim 6, wherein determining that the CH condition is not present comprises determining that the CH parameter exceeds a second CH threshold. ### Claim 8 (depends on 1) The method of claim 1, further comprising receiving from a network node an indication that the UE is allowed to perform optimizations based on the CH parameter. ### Claim 9 A method performed by a network node, the method comprising: obtaining a channel hardening (CH) parameter corresponding to a user equipment (UE); and sending to the UE an indication that the UE is allowed to perform optimizations based on the obtained CH parameter. ### Claim 10 (depends on 9) The method of claim 9, further comprising collecting statistics regarding CH conditions at the UE. ### Claim 11 (depends on 9) The method of claim 9, further comprising signaling to the UE the CH parameter. ### Claim 12 (depends on 9) The method of claim 9, wherein obtaining the CH parameter comprises receiving the CH parameter from the UE. ### Claim 13 (depends on 9) The method of claim 9, further comprising adapting transmission of synchronization and reference signals based on the obtained CH parameter. ### Claim 14 (depends on 13) The method of claim 13, wherein adapting transmission of synchronization and reference signals based on the obtained CH parameter comprises reducing transmission of synchronization signal blocks (SSBs) and channel state information reference signals (CSI-RSs) based on the UE being in a CH condition. ### Claim 15 A user equipment (UE) configured to: obtain an indication that a channel hardening (CH) condition is present; based on the indication that the CH condition is present, obtain a CH parameter; determine that the obtained CH parameter is less than a first CH threshold; in response to the obtained CH parameter being less than the first CH threshold, change a measurement parameter based on the obtained CH parameter; and adapt a measurement procedure in accordance with the changed parameter. ### Claim 16 (depends on 15) The UE according to claim 15, wherein the measurement procedure is a radio resource management (RRM) measurement which involves measuring a quantity including one or more of a channel quality indicator (COI), a reference signal received power (RSRP), a reference signal received quality (RSRQ), and a carrier received signal strength indicator (RSSI). ### Claim 17 A network node configured to: obtain a channel hardening (CH) parameter corresponding to a user equipment (UE); and send to the UE an indication that the UE is allowed to perform optimizations based on the obtained CH parameter. ### Claim 18 (depends on 17) The network node according to claim 17, wherein the network node is further configured to collect statistics regarding CH conditions at the UE.
