Abstract
Embodiments described herein provide a method in a network node for configuring interference measurements for a wireless device. According to the method, the network node receives (804) information indicating whether a channel state information interference measurement, CSI-IM, resource configuration restriction applies for the wireless device. The network node further configures (806) CSI-IM resources for the wireless device based on the information.
Claims29
A method performed by a network node for configuring interference measurements for a wireless device, the method comprising:
- receiving, from the wireless device, information indicating whether a channel state information interference measurement (CSI-IM) resource configuration restriction applies for the wireless device, wherein the information indicates whether the wireless device is restricted to receiving CSI-IM resource configurations that are all completely overlapping with one zero-power channel-state information reference signal (CSI-RS) resource configuration which can be configured for the wireless device;
- and
- configuring CSI-IM resources for the wireless device based on the information.
A network node for configuring interference measurements for a wireless device, the network node comprising a processor and a memory, the memory containing instructions executable by the processor, whereby the network node is operable to:
- receive, from the wireless device, information indicating whether a channel state information interference measurement (CSI-IM) resource configuration restriction applies for the wireless device, wherein the information indicates whether the wireless device is restricted to receiving CSI-IM resource configurations that are all completely overlapping with one zero-power channel-state information reference signal (CSI-RS) resource configuration which can be configured for the wireless device;
- and
- configure CSI-IM resources for the wireless device based on the information.
A method performed by a wireless device for performing channel state information (CSI) measurements, the method comprising:
- transmitting, to a network node, information indicating whether a channel state information interference measurement (CSI-IM) resource configuration restriction applies for the wireless device, wherein the information indicates whether the wireless device is restricted to receiving CSI-IM resource configurations that are all completely overlapping with one zero-power channel-state information reference signal (CSI-RS) resource configuration which can be configured for the wireless device;
- receiving, from the network node, one or more CSI-IM resource configurations, wherein the configurations are dependent on whether the CSI-IM resource configuration restriction applies for the wireless device;
- and
- performing measurements in accordance with the received one or more configurations, and transmitting one or more CSI reports comprising the measurements to the network node.
A wireless device configured for performing channel state information (CSI) measurements, the wireless device comprising a processor and a memory, wherein the memory contains instructions executable by the processor, whereby the wireless device is operable to:
- transmit, to a network node, information indicating whether a CSI-IM resource configuration restriction applies for the wireless device, wherein the information indicates whether the wireless device is restricted to receiving CSI-IM resource configurations that are all completely overlapping with one zero-power channel-state information reference signal (CSI-RS) resource configuration which can be configured for the wireless device;
- receive, from the network node, one or more CSI-IM resource configurations, wherein the configurations are dependent on whether the CSI-IM resource configuration restriction applies for the wireless device;
- perform measurements in accordance with the received one or more configurations, and transmit one or more CSI reports comprising the measurements to the network node.
