Claim Text:
1. A method for optimizing a cloud based radio access network (RAN), comprising: transmitting a first message from a base station to a user equipment (UE); determining that a second message from the user equipment (UE) in response to the first message from the base station is not received by a media access control (MAC) scheduler within a selected amount of time, the MAC scheduler residing remotely at a MAC layer in a cloud; delaying re-transmission of the first message or transmitting a third message from the base station to the UE in response to determining that the second message from the UE is not received by the MAC scheduler within the selected amount of time; and scheduling other hybrid automatic repeat request (HARQ) processes of the UE or other UEs in intervening sub-frames after delaying re-transmission of the first message or transmitting of the third message from the base station to the UE.
