Abstract: Methods, systems, and apparatuses are provided for enhancing timing alignment for uplink (UL) multi-Transmission/Reception Point (TRP) (or mTRP) scenarios in a wireless communication system. A method for a UE in a wireless communication system can comprise receiving a signaling, wherein the signaling indicates activation for a first TRP and/or is a Physical Downlink Control Channel (PDCCH) signal, determining to perform a first random access procedure on the first TRP, based on the signaling, to obtain a first Time Alignment (TA) information associated with the first TRP, and performing multi-TRP operation on the first TRP associated with the first TA information and a second TRP associated with a second TA information.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives, from a first cell, a first signaling indicative of a configuration of a Physical Downlink Control Channel (PDCCH) of a second cell. The UE receives, from the first cell, a second signaling indicative of switching a Special Cell (SpCell) of the UE to the second cell, wherein the second signaling includes a PDCCH signaling and/or a Medium Access Control (MAC) Control Element (CE). The UE monitors the PDCCH of the second cell in response to receiving the second signaling.

A method for a UE comprises performing a SL communication associated with a destination Identity (ID), having a SL DRX configuration associated with the SL communication, wherein the SL DRX configuration comprises at least an on-duration timer and a DRX cycle, deriving a first offset associated with the SL communication based on the destination ID and the DRX cycle, deriving a second offset associated with the SL communication based on the destination ID and a number of slots per subframe, starting the on-duration timer after a time period determined based on the second offset from the beginning of a subframe, wherein the subframe is determined based on at least the first offset, and monitoring Sidelink Control Information (SCI) when the on-duration timer is running.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives a first Radio Resource Control (RRC) message indicative of switching a Primary Cell (PCell) of the UE to a first cell, wherein the first RRC message is indicative of a first configuration of the first cell. The UE resets a Medium Access Control (MAC) entity associated with the PCell of the UE in response to receiving the first RRC message. The UE receives a second RRC message indicative of a second configuration of a second cell. The UE receives a signaling indicative of initiating a mobility procedure to switch the PCell of the UE to the second cell. The signaling includes a Physical Downlink Control Channel (PDCCH) signaling and/or a MAC Control Element (CE). The UE does not reset the MAC entity associated with the PCell of the UE in response to the mobility procedure.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a first device configured to discontinuously monitor one or more sidelink control channels, the first device performs a first sidelink transmission to a second device. In response to the first sidelink transmission, the first device starts or restarts a timer. The first device monitors a first sidelink control channel, from at least the second device, when the timer is running.

Abstract: Methods and apparatuses are provided for ensuring, for a unified TCI framework, a MAC CE format for associating code-point of a TCI field, and a TCI state for DL/UL beam indications. A UE can receive a MAC CE for associating at least one TCI state with at least one code-point of a TCI field in a DCI, wherein the MAC CE comprises at least a first octet including a first TCI state ID field associated with a first TCI state and a first field indicating DL or UL for the first TCI state, a second octet including a second TCI state ID field associated with a second TCI state and a second field indicating DL or UL for the second TCI state, and a third octet including a third field for the UE to determine whether the first TCI state and the second TCI state are associated with a same code-point or different code-points of the TCI field.

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.

Abstract: A method and apparatus are disclosed. In an example, a first device receives first information and second information from a base station. The first device is configured with a configured grant for sidelink communication via the first information. The configured grant is indicative of first resources for sidelink communication. The second information is indicative of one or more timing offsets and an identity for second resources. The first device transmits sidelink data to a second device via a first resource of the first resources. The first device receives and/or detects a first signal, from the second device, indicative of a reception result associated with the sidelink data. The first device determines a second time and a frequency location based on the second information. The first device transmits a second signal to the base station via a second resource associated with the second time and the frequency location.
