Layer 1 and layer 3 measurement coordination
A user equipment (UE) may be configured to perform layer 1 (L1) measurement procedures and layer 3 (L3) measurement procedures. 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.
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.
2. The processor of claim 1 , wherein the CSI-RS L3 measurement window is configured with a predetermined fixed duration.
3. The processor of claim 2 , wherein the CSI-RS L3 measurement window is configured for intra-frequency measurements.
4. The processor of claim 2 , wherein the CSI-RS L3 measurement window is configured for inter-frequency measurements.
5. The processor of claim 1 , wherein the CSI-RS L3 measurement window is configured with an adaptive duration.
6. 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.
7. 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.
8. 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.
9. 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.
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.
11. The UE of claim 10 , wherein the CSI-RS L3 measurement window is configured for intra-frequency measurements.
12. The UE of claim 10 , wherein the CSI-RS L3 measurement window is configured for inter-frequency measurements.
13. 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.
14. 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.
15. 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.
16. 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.
