Abstract: This disclosure is directed radio link control (RLC) and media access control (MAC) protocol data unit (PDU) transmission and retransmission in wireless networks, and is particularly directed to methods and systems for preventing inconsistency in RLC transmission status reports, and for resolving such inconsistency. The disclosed solutions either proactively prevent or reduce the likelihood of the occurrence of such inconsistency at the MAC layer or provide remedial measures at the RLC layer after an inconsistent RLC report is received. The disclosed methods and systems help improving network efficiency.

Abstract: The present disclosure relates to methods, systems, and devices for providing fast mobility. In one form, a processor of user equipment detects a trigger event associated with activating or switching to one or more transmission control indication (TCI) states of a TCI states set associated with a first physical cell ID (PCI) for uplink (UL) and downlink (DL) transmission when one or more TCI states for a TCI state set associated with a second PCI is used by the user equipment for at least one of UL or DL transmission in one serving cell. The processor of the user equipment may then perform a procedure of activating or switching to the one or more TCI states of a TCI state set associated with the first PCI for UL and DL transmission in one serving cell.

Abstract: The present disclosure relates to methods, systems, and devices for providing fast mobility. In one form, a processor of user equipment initiates a random access procedure in one serving cell. Further, the processor of the user equipment selects a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) associated with a transmission control indication (TCI) state associated with a first physical cell ID (PCI), the SSB or the CSI-RS having a reference signaling received power (SSB-RSRP or CSI RSRP) that is above a threshold value.

Abstract: Methods, apparatus, and systems for a beam failure recovery on one or more secondary cells are described. In one example aspect, a wireless communication method includes receiving, by a first device, parameters configured to carry out beam failure detection and beam failure recovery for secondary cells associated with the first device, determining, by the first device, whether a beam failure event has occurred on at least one of the secondary cells based on at least one of the parameters, performing, upon a determination that the beam failure event has occurred, a beam failure recovery procedure for the secondary cell with the beam failure event, and terminating the beam failure recovery procedure upon an occurrence of a termination event.

Abstract: The present disclosure relates to to methods, systems, and devices for performing a discontinuous reception operation for radio link failure and beam failure. In some forms, a method for wireless communication includes user equipment detecting a beam failure tendency for a serving cell of one discontinuous reception (DRX) group or a radio link failure tendency for the serving cell of one DRX group, and in response, either suspending the discontinuous reception operation at the user equipment or adjusting, with the processor, a duration of a subsequent discontinuous reception cycle for the DRX group that the serving cell belongs to. By aborting a currently configured DRX operation or shortening a duration of subsequent DRX cycles, the user equipment is able to more quickly recover from a beam failure or a radio link failure.

Abstract: Some techniques for efficiently indicating a mapping relationship from physical random access channel preambles and/or random access resource specific to one or more system information blocks in a wireless communication network are described. One example method includes transmitting, from a network node, a message that identifies a number of random access preambles that are reserved for transmissions of system information requests by mobile devices.

Abstract: In wireless communication, a device may change, add, or handover between cells of network access for inter-cell mobility. This may include Layer 1 and/or Layer 2 (L1/L2) signaling for a user equipment (UE) moving between cells in a network. The signaling can reduce the mobility interruption time and improve robustness of a handover. The movement may be triggered by the network or the UE. A Layer 1 and/or Layer 3 (L1/L3) measurement is used for the inter-cell mobility. The mobility may be coordinated based on interactions between a centralized unit (CU) and a distributed unit (DU). The procedures can reduce interruption time and improve reliability.

Abstract: This disclosure relates to methods and devices for managing measurement of quality of the radio link between the wireless network access node and the user equipment in a wireless communication system. In one implementation, the method may include obtaining, by a user equipment, an information on adjusting an indication period. The indication period may represent a time period during every which a radio link quality indication being sent to an upper layer of the user equipment. The radio link quality indication may indicate quality of a radio link between the user equipment and a wireless access network node. The method may further include determining, based on the information, whether to adjust the indication period.
