摘要： A method of wireless communication is provided. The method includes performing a first Medium Access Control (MAC) procedure on a first radio access interface for a first Sidelink (SL) connection between the UE and a target UE of a first destination on a second radio access interface; and releasing or canceling the first MAC procedure in a case that the UE is indicated to perform an MAC reset operation associated with the first SL connection based on at least one triggering event associated with the target UE and the second radio access interface.

摘要： Methods, apparatuses, and computer-readable media are described for configuring Ultra Reliable Low Latency Communication (URLLC) simultaneous transmissions, which can be used to enhance network performance and/or to enhance procedures within the UE to achieve more efficient operations. For example, techniques are described for determining which modulation coding scheme (MCS) table to apply based on various factors. Different techniques are also described for configuring user equipment (UE) with an RNTI based on different considerations.

摘要： The embodiments of the disclosure provide a method for maintaining multi-SIM (Subscriber Identity Module) configuration and user equipment (UE). The method includes: receiving, by the UE, a first multi-SIM support information from a first cell, wherein the first multi-SIM support information is generated and transmitted from a second cell to the first cell via an inter-node signaling from the second cell to the first cell, and the first cell and the second cell belong to a first network; transmitting, by the UE, a multi-SIM assistance information message to the second cell, wherein the multi-SIM assistance information message is determined based on the first multi-SIM support information.

摘要： Some of the present implementations provide a method for a user equipment (UE) for performing a handover procedure with minimum mobility interruption. The method receives, at the UE, a reconfiguration message that has an indicator for performing a dual-connectivity based (DC-based) handover procedure. The method then performs the DC-based handover procedure without reestablishing a packet data convergence protocol (PDCP) entity of the UE during the DC-based handover procedure. The PDCP entity maintains a plurality of security keys to decipher PDCP packets received from at least one of a source base station and a target base station during the handover procedure and while the UE is transitioning from the source base station to the target base station.

摘要： A method for a user equipment (UE) performing a beam failure recovery (BFR) procedure is disclosed. The method comprises performing a first beam failure detection (BFD) procedure on a first cell, performing a second BFD procedure on a second cell, triggering a first BFR procedure for a first cell in response to a beam failure being detected on the first cell by the first BFD procedure, triggering a second BFR procedure for a second cell in response to a beam failure being detected on the second cell by the second BFD procedure, and canceling the triggered first BFR procedure for the first cell in response to a BFR report corresponding to at least one of the first and second BFR procedures being successfully transmitted to a base station (BS), wherein the BFR report includes BFR information of the first cell.

摘要： A method related to physical uplink control channel (PUCCH) cell switching and a user equipment (UE) are provided. The method includes: receiving a radio resource control (RRC) message from a base station; determining a PUCCH cell from the first cell and the second cell according to at least one PUCCH cell pattern; and transmitting the PUCCH transmission on the PUCCH cell during the time resource units. The RRC message includes at least one PUCCH cell pattern associated with multiple cell indexes and a first subcarrier spacing (SCS) associated with a first cell and a second SCS associated with a second cell. Each cell index corresponds to a cell, and the PUCCH cell pattern indicates which cell corresponds to one time resource unit used for PUCCH transmission.

摘要： A method for acquiring system information (SI) performed by a user equipment (UE) in a radio resource control (RRC)_CONNECTED state is provided. The method includes: performing a first set of operations after determining that the UE is not configured with a common search space (CSS) in an active bandwidth part (BWP); and performing a second set of operations after determining that the UE is configured with the CSS in the active BWP. The first set of operations includes: transmitting, to a cell, a first RRC message for requesting a required system information block (SIB) after determining that the required SIB is provided by the cell; and receiving, from the cell, a second RRC message including the required SIB. The second set of operations includes: transmitting, to the cell, a third RRC message for requesting the required SIB after determining that the required SIB is provided by the cell and the required SIB is not broadcast in the cell; and receiving, from the cell, the required SIB in the CSS.

摘要： A method of sidelink unicast service management in an access stratum layer for a first user equipment (UE) is disclosed. The method comprises receiving, by the first UE through a PC5 interface, a sidelink unicast configuration associated with a second UE, from the second UE, transmitting, by the first UE through a radio resource control, RRC, signaling of the PC5 interface, a sidelink unicast link problem report, to the second UE in responsive to that the first UE is unable to comply with all or part of the sidelink unicast configuration, and performing, by the first UE, a sidelink unicast fallback procedure with the second UE by continuously using a sidelink unicast configuration setting of the first UE with corresponding configurations in a sidelink unicast pre-configuration used prior to the received sidelink unicast configuration.
