The UE configures a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, identifies a collision between a layer 1 (L1) measurement operation and a L3 measurement operation and omits at least one L1 measurement in response to identifying the collision. ## Claims ### Claim 1 A processor of a user equipment (UE) configured to perform operations comprising: configuring a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, wherein a starting point of the CSI-RS L3 measurement window is a starting boundary of a slot in which a first configured CSI-RS resource is located; identifying a collision between a layer 1 (L1) measurement operation and a L3 measurement operation; and omitting at least one L1 measurement in response to identifying the collision. ### Claim 2 (depends on 1) The processor of claim 1, wherein the CSI-RS L3 measurement window is configured with a predetermined fixed duration. ### Claim 3 (depends on 2) The processor of claim 2, wherein the CSI-RS L3 measurement window is configured for intra-frequency measurements. ### Claim 4 (depends on 2) The processor of claim 2, wherein the CSI-RS L3 measurement window is configured for inter-frequency measurements. ### Claim 5 (depends on 1) The processor of claim 1, wherein the CSI-RS L3 measurement window is configured with an adaptive duration. ### Claim 6 (depends on 1) The processor of claim 1, wherein identifying the collision between the L1 and L3 measurement operations is based on identifying that a L1 measurement resource fully overlaps in time with the CSI-RS L3 measurement window. ### Claim 7 (depends on 1) The processor of claim 1, wherein identifying the collision between the L1 and L3 measurement operations is based on identifying that a L1 measurement resource partially overlaps in time with the CSI-RS L3 measurement window. ### Claim 8 (depends on 1) The processor of claim 1, wherein identifying the collision between the L1 and L3 measurement operations is based on identifying that a time gap between a L1 measurement resource and the CSI-RS L3 measurement resource is less than a predetermined threshold. ### Claim 9 (depends on 1) The processor of claim 1, wherein the operations further comprising one of: determining that a set of periodic or semi-persistent L1 measurement resources fully overlap with a set of multiple CSI-RS L3 measurement windows, or determining that a set of periodic or semi-persistent L1 measurement resources partially overlap with a set of multiple CSI-RS L3 measurement windows. ### Claim 10 A user equipment (UE), comprising: a transceiver configured to communicate with a network; and a processor communicatively coupled to the transceiver and configured to perform operations comprising: configuring a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, wherein the CSI-RS L3 measurement window is configured with an adaptive duration and a starting point of the CSI-RS L3 measurement window is a starting boundary of a slot in which a first configured CSI-RS resource is located; identifying a collision between a layer 1 (L1) measurement operation and a L3 measurement operation; and omitting at least one L1 measurement in response to identifying the collision. ### Claim 11 (depends on 10) The UE of claim 10, wherein the CSI-RS L3 measurement window is configured for intra-frequency measurements. ### Claim 12 (depends on 10) The UE of claim 10, wherein the CSI-RS L3 measurement window is configured for inter-frequency measurements. ### Claim 13 (depends on 10) The UE of claim 10, wherein an ending point of the CSI-RS L3 measurement window is an ending boundary of a slot in which a last configured CSI-RS resource is located. ### Claim 14 (depends on 10) The UE of claim 10, wherein an ending point of the CSI-RS L3 measurement window is an ending boundary a last configured CSI-RS resource. ### Claim 15 (depends on 10) The UE of claim 10, wherein an ending point of the CSI-RS L3 measurement window is an ending boundary of a slot that is a predetermined number of slots after a slot in which a last configured CSI-RS resource is located. ### Claim 16 (depends on 10) The UE of claim 10, wherein an ending point of the CSI-RS L3 measurement window is an ending boundary of a symbols that is a predetermined number of symbols after a last configured CSI-RS resource.
