Abstract
A method performed by a User Equipment (UE) is performed. The UE obtains (202) a beam reporting configuration. The beam reporting configuration defines a beam reporting procedure for determining an optimal beam for each of different sub-bands of a system bandwidth. The UE measures (204) different reference signals transmitted by the network node. The measured different reference signals correspond to each of the different sub-bands according to the beam reporting configuration. The UE then determines (206) a preferred beam for each of the different sub-bands based on the corresponding received reference signals.
Claims24
A method performed by a User Equipment (UE), the method comprising:
- obtaining a beam reporting configuration defining a beam reporting procedure for determining an optimal beam for each of different sub-bands of a system bandwidth;
- measuring, according to the beam reporting configuration, different reference signals transmitted by a network node corresponding to each of the different sub-bands;
- and
- determining a preferred beam for each of the different sub-bands based on the corresponding received reference signals.
A User Equipment (UE), comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the UE is operative to:
- obtain a beam reporting configuration defining a beam reporting procedure for determining an optimal beam for each of different sub-bands of a system bandwidth;
- measure, according to the beam reporting configuration, different reference signals transmitted by the network node corresponding to each of the different sub-bands;
- and
- determine a preferred beam for each of the different sub-bands based on the corresponding received reference signals.
A method performed by a network node, the method comprising:
- determining a beam reporting configuration defining a beam reporting procedure to be utilized by a User Equipment (UE) for determining an optimal beam for each of different sub-bands of a system bandwidth;
- signaling the beam reporting configuration to the UE;
- transmitting different reference signals to the UE according to the beam reporting configuration, the different reference signals corresponding to each of the different sub-bands;
- and
- receiving a beam reporting message from the UE, the beam reporting message indicating a preferred beam for each of the different sub-bands.
