## Abstract

Embodiments herein provide techniques and requirements for radio resource management (RRM) measurements. For example, embodiments include techniques and requirements associated with: channel state information (CSI)-reference signal (RS) based inter-frequency RRM measurements when the CSI-RS bandwidth and the active downlink (DL) bandwidth part (BWP) are partially overlapped; adaptive RRM CSI-RS configuration and DL gap allocation by user equipment (UE) capability indication; and/or neighboring cell RRM CSI-RS measurement requirements when serving cell RRM CSI-RS is not configured. Other embodiments may be described and claimed.

## Claims

### Claim 1

One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to:
determine a resource block (RB) allocation for a radio resource management (RRM) channel state information reference signal (CSI-RS);
determine a bandwidth configuration for a serving cell in an active downlink (DL) bandwidth part (BWP), wherein the RB allocation for the RRM CSI-RS partially overlaps with the bandwidth configuration; and
select a measurement mode for performing an RRM measurement on the CSI-RS, wherein the measurement mode is a selected one of:
a first measurement mode in which reception of active DL BWP is interrupted for a measurement gap and the RRM CSI-RS is measured within the measurement gap; or
a second measurement mode in which only a portion of the RRM CSI-RS that overlaps with the bandwidth configuration of the active DL BWP is measured;
wherein the measurement mode is selected based on a number of RBs in the RB allocation that are overlapped with the bandwidth configuration.

### Claim 2 (depends on 1)

The one or more NTCRM of claim 1, wherein the first measurement mode is selected if the number of RBs is less than a threshold and the second measurement mode is selected if the number of RBs is greater than the threshold.

### Claim 3 (depends on 1)

The one or more NTCRM of claim 1, wherein the instructions, when executed, are further to cause the UE to perform the RRM measurement on the CSI-RS according to the selected measurement mode.

### Claim 4 (depends on 1)

The one or more NTCRM of claim 1, wherein the RRM measurement is performed on the entire RB allocation for the RRM CSI-RS in the first measurement mode.

### Claim 5 (depends on 1)

The one or more NTCRM of claim 1, wherein in the second measurement mode the active DL BWP is received in RBs of the active DL BWP that overlap with the RB allocation for the RRM CSI-RS.

### Claim 6 (depends on 1)

The one or more NTCRM of claim 1, wherein the RRM CSI-RS is transmitted on a different cell from the active DL BWP.

### Claim 7

One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to:
determine a resource block (RB) allocation for a radio resource management (RRM) channel state information reference signal (CSI-RS);
determine a bandwidth configuration for a serving cell in an active downlink (DL) bandwidth part (BWP), wherein the RB allocation for the RRM CSI-RS partially overlaps with the bandwidth configuration;
identify that a number of RBs in the RB allocation that are overlapped with the bandwidth configuration is greater than a threshold; and
based on the identification:
interrupt reception of the active DL BWP for a measurement gap; and
perform an RRM measurement on the RRM CSI-RS during the measurement gap.

### Claim 8 (depends on 7)

The one or more NTCRM of claim 7, wherein the RRM measurement is performed on the entire RB allocation for the RRM CSI-RS.

### Claim 9 (depends on 7)

The one or more NTCRM of claim 7, wherein the RRM CSI-RS is transmitted on a different cell from the active DL BWP.
