Abstract: Methods and apparatuses for improving uplink transmissions in a wireless communication system are disclosed herein. In one method, a user equipment receives an indication indicating a type of data that can be transmitted using a cooperation mode. A first data is transmitted using the cooperation mode, in which the first data belongs to the type of data using the cooperation mode based on the indication. A second data is transmitted without using the cooperation mode, in which the second data does not belong to the type of data using the cooperation mode based on the indication. The cooperation mode is enabled when transmitting the first and second data.

Abstract: Methods and apparatuses for recovering a Radio Resource Control (RRC) connection in a wireless communication system are disclosed herein. In one method, a user equipment (UE) performs a procedure used to re-establish a RRC connection between the UE and a network node. The UE enters a RRC_INACTIVE state when the procedure is failed and if the UE has at least one parameter of the RRC_INACTIVE state. The UE enters a RRC_IDLE state when the procedure is failed and if the UE does not have the at least one parameter of the RRC_INACTIVE state.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE maintains a first counter and a second counter, wherein the first counter and the second counter are associated with a Special Cell (SpCell) and are for counting beam failure instance indications. The UE initiates a first beam failure recovery (BFR) procedure based on the first counter being equal to or larger than a value, wherein the first BFR procedure includes initiating a random access procedure for SpCell BFR associated with the SpCell. The UE sets the first counter and the second counter to a defined value in response to completion of the first BFR procedure.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives an uplink (UL) grant. The UL grant is indicative of a first Physical Uplink Shared Channel (PUSCH) transmission on a first Transmission/Reception Point (TRP) of a first cell. The UL grant is indicative of a second PUSCH transmission on a second TRP of the first cell. The UE transmits a Power Headroom Reporting (PHR) Medium Access Control (MAC) Control Element (CE). Based on the UL grant, the PHR MAC CE is indicative of a first power headroom (PH), associated with the first TRP, based on a real PUSCH transmission, and is indicative of a second PH, associated with the second TRP, based on a reference PUSCH transmission. The second PUSCH transmission is performed after transmitting the PHR MAC CE.
