Abstract
Embodiments of the present disclosure provide a solution for CSI reporting. In a method for communication, a terminal device receives one or more configurations for at least one of a first Channel State Information (CSI), a second CSI or a third CSI in a CSI reporting setting. The one or more configurations in the CSI reporting setting include at least one of at least two rank restrictions or at least two codebook subset restrictions (CBSRs). The terminal device transmits, to a network device, at least one of the first CSI, the second CSI or the third CSI based on the one or more configurations.
Claims22
A method, performed by a terminal device, the method comprising:
- receiving a configuration comprising a first Rank Indicator (RI) restriction and a second RI restriction,
- wherein the first RI restriction indicates a restriction for RI for one or more resource pairs in a channel state information reference signal (CSI-RS) resource set,
- wherein a first CSI-RS resource indicator (CRI) corresponds to a resource pair among the one or more resource pairs,
- wherein a bit size of the second RI restriction is 8, and
- wherein the second RI restriction indicates a restriction for RI, which is applied to a third RI associated with one CSI-RS resource in the CSI-RS resource set;
- and
- transmitting a channel state information (CSI) report based on the configuration.
A method, performed by a network device, the method comprising:
- transmitting a configuration comprising a first Rank Indicator (RI) restriction and a second RI restriction,
- wherein the first RI restriction indicates a restriction for RI for one or more resource pairs in a channel state information reference signal (CSI-RS) resource set,
- wherein a first CSI-RS resource indicator (CRI) corresponds to a resource pair among the one or more resource pairs,
- wherein a bit size of the second RI restriction is 8, and
- wherein the second RI restriction indicates a restriction for RI, which is applied to a third RI associated with one CSI-RS resource in the CSI-RS resource set;
- and
- receiving a channel state information (CSI) report based on the configuration.
A terminal device, comprising a processor configured to cause the terminal device to:
- receive a configuration comprising a first Rank Indicator (RI) restriction and a second RI restriction,
- wherein the first RI restriction indicates a restriction for RI for one or more resource pairs in a channel state information reference signal (CSI-RS) resource set,
- wherein a first CSI-RS resource indicator (CRI) corresponds to a resource pair among the one or more resource pairs,
- wherein a bit size of the second RI restriction is 8, and
- wherein the second RI restriction indicates a restriction for RI, which is applied to a third RI associated with one CSI-RS resource in the CSI-RS resource set;
- and
- transmit a channel state information (CSI) report based on the configuration.
A network device comprising a processor configured to cause the network device to:
- transmit a configuration comprising a first Rank Indicator (RI) restriction and a second RI restriction,
- wherein, the first RI restriction indicates a restriction for RI for one or more resource pairs in a channel state information reference signal (CSI-RS) resource set,
- wherein a first CSI-RS resource indicator (CRI) corresponds to a resource pair among the one or more resource pairs,
- wherein a bit size of the second RI restriction is 8, and
- wherein the second RI restriction indicates a restriction for RI, which is applied to a third RI associated with one CSI-RS resource in the CSI-RS resource set;
- and
- receive a channel state information (CSI) report based on the configuration.
