Method and apparatus for transmitting/receiving channel state information (CSI) on nonoverlapping physical uplink control channel (PUCCH) resources

A communication device configured to operate in a wireless communication system, the communication device comprising:

• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• determining a first channel state information (CSI) report with a first highest priority among a plurality of CSI reports, wherein the plurality of CSI reports corresponds to a plurality of non-overlapped Physical Uplink Control Channel (PUCCH) resources in a same time interval, wherein the first CSI report corresponds to a first PUCCH resource among the plurality of non-overlapped PUCCH resources;
• determining a second CSI report with a second highest priority among the plurality of CSI reports, based on which format the first PUCCH resource having, wherein the second CSI report corresponds to a second PUCCH resource among the plurality of non-overlapped PUCCH resources;
• and
• transmitting the first CSI report and the second CSI report using the first PUCCH resource and the second PUCCH resource, respectively,
• wherein, based on (i) the first PUCCH resource having a first format, and (ii) one or more remaining PUCCH resources, other than the first PUCCH resource among the plurality of non-overlapped PUCCH resources, having a second format:
• the second CSI report is determined as a CSI report with a highest priority among CSI reports corresponding to the one or more remaining PUCCH resources having the second format,
• wherein, based on the first PUCCH resource having the second format:
• the second CSI report is determined as a CSI report with a highest priority among CSI reports corresponding to all remaining PUCCH resources, other than the first PUCCH resource, and
• wherein the first PUCCH resource of the first format has at least a first number of symbols, the second PUCCH resource of the second format has at most a second number of symbols, and the first number is greater than the second number.

A method of receiving control information by a communication device in a wireless communication system, the method comprising:

• determining a first channel state information (CSI) report with a first highest priority among a plurality of CSI reports, wherein the plurality of CSI reports corresponds to a plurality of non-overlapped Physical Uplink Control Channel (PUCCH) resources in a same time interval, wherein the first CSI report corresponds to a first PUCCH resource among the plurality of non-overlapped PUCCH resources;
• determining a second CSI report with a second highest priority among the plurality of CSI reports, based on which format the first PUCCH resource having, wherein the second CSI report corresponds to a second PUCCH resource among the plurality of non-overlapped PUCCH resources;
• and
• receiving the first CSI report and the second CSI report using the first PUCCH resource and the second PUCCH resource, respectively,
• wherein, based on (i) the first PUCCH resource having a first format, and (ii) one or more remaining PUCCH resources, other than the first PUCCH resource among the plurality of non-overlapped PUCCH resources, having a second format:
• the second CSI report is determined as a CSI report with a highest priority among CSI reports corresponding to the one or more remaining PUCCH resources having the second format,
• wherein, based on the first PUCCH resource having the second format:
• the second CSI report is determined as a CSI report with a highest priority among CSI reports corresponding to all remaining PUCCH resources, other than the first PUCCH resource, and
• wherein the first PUCCH resource of the first format has at least a first number of symbols, the second PUCCH resource of the second format has at most a second number of symbols, and the first number is greater than the second number.
