Abstract
A method in a wireless device for reporting Channel State Information (CSI). The wireless device is comprised in a wireless communications system. The method includes receiving a CSI process configuration and a request for CSI information from a network node. The method further includes reporting CSI for one or more CSI processes. The CSI reflects the state of the channel for a CSI reference resource. According to the method, the CSI reference resource is determined based on the number of configured CSI processes. Related devices are also disclosed.
Claims18
A method, in a wireless device, for reporting Channel State Information (CSI), the wireless device being comprised in a wireless communications system, the method comprising:
- receiving a CSI process configuration and a request for CSI from a network node;
- determining a CSI reference resource based on a numerical indicator indicating a total number of configured CSI processes;
- and reporting CSI for one or more CSI processes, wherein the CSI reflects a state of a channel for the CSI reference resource;
- wherein determining the CSI reference resource comprises determining, as a function of how many CSI processes are configured for the wireless device, a location of the CSI reference resource in the time domain.
A wireless device for reporting Channel State Information (CSI), the wireless device comprising:
- memory comprising instructions;
- processing circuitry operatively connected to the memory and configured, when executing the instructions, to cause the wireless device to:
- receive, from a network node, a CSI process configuration and a request for CSI;
- determine a CSI reference resource based on a numerical indicator indicating a total number of configured CSI processes;
- and report CSI for one or more CSI processes, wherein the CSI reflects a state of a channel for the CSI reference resource;
- wherein the processing circuitry is operatively connected to the memory and is configured, when executing the instructions, to cause the wireless device to determine, as a function of how many CSI processes are configured for the wireless device, a location of the CSI reference resource in the time domain.
A computer program product stored on a non-transitory computer readable medium and comprising program instructions, which when executed by at least one processor, causes the at least one processor to:
- receive, from a network node, a CSI process configuration and a request for CSI;
- determine a CSI reference resource based on a numerical indicator indicating a total number of configured CSI processes;
- and
- report CSI for one or more CSI processes, wherein the CSI reflects a state of a channel for the CSI reference resource;
- wherein the at least one processor is configured, when executing the instructions, to cause a wireless device to determine, as a function of how many CSI processes are configured for the wireless device, a location of the CSI reference resource in the time domain.
