Abstract: This disclosure is directed to UE measurements and measurement report of serving cells, and configuration for the cell measurement and report to effectuate a fast serving-cell change during UE mobility within lower network layers, such as layer-1 or layer-2 of the wireless communication protocol stack. This disclosure is further directed to signaling procedures associated with the fast serving-cell change for the UE as triggered by the network based on the cell measurement and report, and various lower layer configurations and operations for effectuating an actual fast serving-cell change at and for the UE.

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 transmission or retransmission on shared spectrum channel in a wireless communication network. In one implementation, the method may include determining if an uplink grant is deprioritized by a uplink shared channel transmission on a shared spectrum channel. The method may further include determining if a media access control (MAC) data packet has been generated for the deprioritized uplink grant. The method may further include, in response to the uplink grant being deprioritized and the MAC data packet being generated for the deprioritized uplink grant, performing a retransmission of the MAC data packet with an available uplink grant.

Abstract: The disclosed techniques enable communication nodes to perform rate adjustments. As an example, a communication node may receive a control information from a network node. Based on the received control information, the control node may determine that the network node supports codec adaptation or that the communication node is allowed to enable the codec adaptation.

Abstract: This disclosure relates to wireless radio link recovery methods. In various implementations, the method includes determining a beam failure event for a first cell, and transmitting a beam recovery request message on a shared uplink channel when available. In other implementations, the method includes determining that the shared uplink channel is not available for transmitting the beam recovery request message and transmitting a resource request to request allocation of the shared uplink channel via a second cell.

Abstract: A system and method for power headroom reporting (PHR) during a Dual Activity Protocol Structure (DAPS) handover procedure. The system and method include receiving, by a wireless communication device, a handover command to begin a dual activity protocol structure (DAPS) handover; detecting, by the wireless communication device during the DAPS handover, a condition for power headroom reporting (PHR); and performing, by the wireless communication device during the DAPS handover, the PHR.

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.
