or when receiving a request sent by the serving eNodeB, the non-serving eNodeB returns the result information about the joint decoding performed by the non-serving eNodeB on the information sent by the UE to the serving eNodeB.

8. The method according to claim 1, further comprising:

sending a fourth indication message to the UE, where the fourth indication message is used to indicate whether multiple cells that currently receive the information sent by the UE are located in the same eNodeB.

9. The method according to claim 1, further comprising:

if returning the feedback message in response to the information sent by the UE to the UE is delayed, sending, by the serving eNodeB, delay indication to the UE, wherein the delay indication is used to instruct the UE to receive delay information about the feedback message, and the delay information comprises delay time for the UE receiving the feedback message.

10. An information processing method, comprising:

receiving, by a non-serving evolved NodeB (eNodeB), information sent by user equipment (UE) and performing joint decoding by the non-serving eNodeB on the information sent by the UE;

obtaining, by the non-serving eNodeB, result information about the joint decoding; and
