Abstract: A system and method for improving mobility performance. The system and method include receiving, by a target master wireless communication node (MN) from a source master wireless communication node (MN), a handover request to begin a handover procedure; and transmitting, by the target MN to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, wherein the first message causes the target SN to send a second message to the target MN to inform the target MN of one or more configured primary secondary (PSCells).

Abstract: A method includes receiving a first radio resource control (RRC) message including at least one of a conditional handover (CHO) configuration and a conditional primary secondary cell addition or change (CPAC) configuration. The CHO configuration includes a CHO configuration index, a CHO candidate cell configuration, and a CHO execution condition. The CPAC configuration includes a CPAC configuration index, a CPAC candidate cell configuration, and a CPAC execution condition. The method includes selecting, responsive to receiving the first RRC message and based on at least one of the CHO execution condition and the CPAC execution condition, a special cell (SpCell) of a wireless communication node to perform a random access procedure (RAP); and transmitting, to the wireless communication node, a second RRC message to inform the wireless communication node that the wireless communication device selected the SpCell to perform the RAP.

Abstract: Presented are systems and methods for transmission of preamble and payload messages in random access procedures. A wireless communication device may transmit, in a random access (RA) procedure, a RA preamble and a corresponding uplink channel payload to a wireless communication node. The wireless communication device may retransmit, to the wireless communication node, the corresponding uplink channel payload through an uplink grant, responsive to a failure of the transmitted uplink channel payload for the wireless communication node.

Abstract: User equipment may request to communicate with a basestation over a contention-based wireless communication channel. The basestation and the user equipment may perform a multiple-step random access protocol to determine whether the user equipment may communicate over the wireless communication channel. The architecture, e.g., the fields and structure of the messages sent by the basestation may indicate the content and type of those same messages.

Abstract: Methods, apparatus, and systems for wireless communication are described. In one example aspect, a method includes performing, by a communication node, a handover procedure from a source base station to a target base station based on information associated with a Protocol Data Unit (PDU) session. The information indicates that at least one tunnel in a list of tunnels that carry user data has a one-to-one correspondence with a Quality of Service (QoS) flow. The method also includes transmitting, for the handover procedure, downlink data to both the source base station and the target base station by the communication node.

Abstract: Methods and devices for data and control messaging in wireless communication systems. In one implementation, the method includes obtaining, by a user equipment, a channel restriction information associated with a control message in response to an uplink grant. The method may also include determining, by the user equipment, whether to transmit the control message based on the channel restriction information. In another implementation, the method may include configuring, by a user equipment, a priority information for a control message in response to an uplink grant. The method may further include allocating resources to the control message and the data message for transmission based on the priority information.
