  • Publication number: 20240147524
    Abstract: To manage communications from a UE during a state transition, a central unit (CU) of a base station performs, by processing hardware, an early data transmission procedure with the UE while the UE is in an inactive state, including transmitting at least one data packet of a sequence of data packets to the UE (802). The CU determines to transition the UE from the inactive state to a connected state (808). In response to transitioning the UE to the connected state, the CU transmits, by the processing hardware, a next data packet in the sequence of data packets to the UE, or retransmits, by the processing hardware, the at least one data packet to the UE in response to determining the at least one data packet has not been received (812).

  • Patent number: 11950307
    Abstract: This document describes techniques and devices for efficient handling of a resource control state change and multi-node connectivity. Instead of performing multiple radio resource control (RRC) procedures to change a resource control state of a user equipment (UE) and establish, modify, or release a connection with multi-node connectivity, the techniques described herein combine the multiple RRC procedures into a single RRC procedure that supports both a resource control state change and multi-node connectivity. In particular, a master node sends a resource control state and multi-node connectivity message that includes both state change information and multi-node connectivity information. With this single message, timing and power resources of the UE can be conserved and failures resulting from asynchronous communication of the state change information and the multi-node connectivity information can be avoided.
