6 . The apparatus according to claim 1 , wherein the retransmission uplink grant corresponds to a hybrid automatic repeat request process identifier of the cancelled first physical uplink shared channel.

7 . The apparatus according to claim 1 , wherein the at least one processor is further configured to cause the apparatus to:

multiplex the at least part of the first set of uplink control information on the second physical uplink shared channel, if there are enough resources on the second physical uplink shared channel for the at least part of the first set of uplink control information.

8 . The apparatus according to claim 1 , wherein the at least one processor is further configured to cause the apparatus to:

reduce a payload size of the first set of uplink control information.

9 . The apparatus according to claim 1 , wherein the at least one processor is further configured to cause the apparatus to: multiplex at least a part of a second set of uplink control information on the second physical uplink shared channel.

10 . The apparatus according to claim 9 , wherein the at least one processor is further configured to cause the apparatus to:

reduce a payload size of the second set of uplink control information.

11 . The apparatus according to claim 9 , wherein the at least one processor is further configured to cause the apparatus to:

compare an importance of the first set of uplink control information and an importance of the second set of uplink control information;

wherein the at least one processor is further configured to cause the apparatus to multiplex the following:

the first set of uplink control information and the at least part of the second set of uplink control information on the second physical uplink shared channel, if the importance of the first set of uplink control information is higher than the importance of the second set of uplink control information, and if there are enough resources on the second physical uplink shared channel for the at least part of the second set of uplink control information in addition to the first set of uplink control information;

the first set of uplink control information on the second physical uplink shared channel, if the importance of the first set of uplink control information is higher than the importance of the second set of uplink control information, and if there are not enough resources on the second physical uplink shared channel for the at least part of the second set of uplink control information in addition to the first set of uplink control information;

the second set of uplink control information and the at least part of the first set of uplink control information on the second physical uplink shared channel, if the importance of the second set of uplink control information is higher than the importance of the first set of uplink control information, and if there are enough resources on the second physical uplink shared channel for the at least part of the first set of uplink control information in addition to the second set of uplink control information; and

the second set of uplink control information on the second physical uplink shared channel, if the importance of the second set of uplink control information is higher than the importance of the first set of uplink control information, and if there are not enough resources on the second physical uplink shared channel for the at least part of the first set of uplink control information in addition to the second set of uplink control information.

12 .
