Method and apparatus for transmitting information on an uplink channel
A PUCCH configuration including information of at least one PUCCH resource can be received ( 310 ) at a UE. An UL grant for at least one high-priority PUSCH can be received ( 320 ). The UL grant can indicate the UE to include a CSI report in the at least one high-priority PUSCH. A particular PUSCH of the at least one high-priority PUSCH can overlap with a PUCCH resource of the at least one PUCCH resource. A determination can be made ( 330 ) as to whether there is UCI to transmit on the PUCCH resource. The particular PUSCH can be transmitted ( 340 ) according to the UL grant by including the CSI report in the particular PUSCH when there is UCI to transmit on the PUCCH resource.

10. The method of claim 9 , wherein the UCI comprises at least one of the SR or hybrid automatic repeat request (HARQ) acknowledgement (ACK) information, or an additional CSI report, and wherein transmitting the at least one high-priority PUSCH comprises:
multiplexing the HARQ ACK information with the at least one high-priority PUSCH based at least in part on the UCI comprising the HARQ ACK information;
excluding the SR from the at least one high-priority PUSCH based at least in part on the UCI comprising the SR; and
excluding the additional CSI report from the at least one high-priority PUSCH based at least in part on the UCI comprising the additional CSI report.
11. The method of claim 1 , wherein the UCI comprises hybrid automatic repeat request (HARQ) acknowledgement (ACK) information, and wherein the at least one high-priority PUSCH comprises a low-priority uplink-shared channel and the HARQ ACK information of the UCI.
12. The method of claim 11 , further comprising indicating that the low-priority uplink-shared channel is transmitted on the at least one high-priority PUSCH.
13. The method of claim 12 , wherein the indicating comprises applying a scrambling sequence to the at least one high-priority PUSCH, where the scrambling sequence corresponds to the low-priority uplink-shared channel.
14.
