摘要： User equipment, a system and a method perform a predetermined data transmission in which the user equipment transmits uplink user data when the user equipment is in a radio resource control (RRC) inactive state. The user equipment, apparatus and method receive from a network node, a first timer value for a RRC connection resume procedure without the predetermined data transmission and a second timer value for a RRC connection resume procedure with the predetermined data transmission, transmit to the network node during a random access procedure, a random access preamble, start a timer configured with the second timer value in response to transmitting a RRC resume message together with the uplink user data, and in response to the timer being expired, determine that the predetermined data transmission is failed.

摘要： A communication control method includes: configuring, for a relay node, dual connectivity in which a first parent node managing a master cell group is a master node and a second parent node managing a secondary cell group is a secondary node; transmitting, by the relay node, a first notification to a child node when a radio link failure is detected in one of a first backhaul link between the relay node and the first parent node and a second backhaul link between the relay node and the second parent node, the first notification indicating detection of the radio link failure; and transmitting, by the relay node, a second notification to the child node when recovery from the radio link failure occurs after transmitting the first notification, the second notification being transmitted after transmitting the first notification and indicating recovery from the radio link failure.

摘要： The methods and systems discussed herein describe how a first wireless communication device forwards a reservation signal, which identifies one or more time-slots that have been reserved by a second wireless communication device, to avoid “merging collisions.” In some examples, the first wireless communication device determines that it should forward the reservation signal based on a determination that the first wireless communication device is located at the edge of a coverage area associated with the second wireless communication device. This determination can be based on location information associated with the second wireless communication device or whether a received power value of the reservation signal is within a pre-defined threshold range value. In other examples, the first wireless communication device transmits an updated forwarded reservation signal, which is an update of a previously forwarded reservation signal in which multiple time-slots were reserved.

摘要： A handover control method for performing a conditional handover of a user equipment from a source cell to a target cell, the source cell to which the user equipment connects. The handover control method comprises transmitting, by a source base station which manages the source cell to the user equipment, a RRC message including a list of candidate cells which are candidates for the target cell and a handover condition specified for each of the candidate cells in the list; and starting, by the source base station, transfer of a copy of downlink data of the user equipment to a candidate base station which manages the candidate cell in the list before the user equipment performs the handover.

摘要： A relay user equipment (UE) device transmits a Radio Resource Control (RRC) connection status indicator indicating the RRC connection status of the relay UE device to a serving base station. The RRC connection status indicator may be used by a remote UE device to manage relay communication to the base station. In one example, a remote UE device in direct communication with the base station transmits a measurement report to the base station where the measurement report includes measurements only for relay UE devices reporting a RRC connected (RRC CONN) status. The base station manages direct to indirect communication switching at least partially based on the measurement report. In another example, a remote UE device manages relay reselection using a relay candidate prioritization at least partially based on the connection status of candidate relay UE devices.

摘要： A user equipment comprises transceiver circuitry and processing circuitry operatively associated with the transceiver circuitry. The transceiver circuitry is configured to execute processes of receiving, from a network, a Radio Resource Control (RRC) message including an instruction to transition to a specific state where an RRC connection of the user equipment is suspended, the RRC message including information indicating a radio resource for uplink transmission; and performing the uplink transmission using the radio resource when the user equipment is in the specific state. A method for a user equipment comprises receiving, from a network, a Radio Resource Control (RRC) message including an instruction to transition to a specific state where an RRC connection of the user equipment is suspended, the RRC message including information indicating a radio resource for uplink transmission; and performing the uplink transmission using the radio resource when the user equipment is in the specific state.

摘要： The devices, systems, and methods discussed herein involve abase station (e.g., gNB) that employs a broadcast technology such as the Multimedia Broadcast Multicast Service (MBMS) to relay hidden-node information to the neighboring UE devices. In some examples, a base station receives at least one report based on data acquired by at least one non-communication sensor of a user equipment (UE) device. Based on the at least one report, the base station transmits a message to another UE device that results in the other UE device refraining from using communication resources that will interfere with transmissions by other UE devices.

摘要： A communication control method according to a first aspect is performed by a user equipment in a mobile communication system for providing a multicast service to the user equipment, the communication control method including monitoring a paging message transmitted from a base station. The monitoring includes: monitoring, when an early paging notification signal is received from the base station, a first paging message that calls one or more user equipments being targets of unicast communication; and monitoring, when the user equipment has joined or is interested in a multicast session, a second paging message that notifies that one or more multicast sessions have been activated even when the early paging notification signal has not been received.

摘要： A communication control method according to a first aspect is a method performed by a user equipment in a mobile communication system for providing a multicast broadcast service (MBS) from a base station to the user equipment. The communication control method includes receiving, from the base station, a PDCP packet encrypted by using a count value including a PDCP sequence number and a hyper frame number and transmitted in an MBS session; generating an inferred hyper frame number by inferring the hyper frame number; attempting decoding of the PDCP packet by using an inferred count value including the PDCP sequence number included in the PDCP packet received and the inferred hyper frame number; and determining the inferred hyper frame number as a valid hyper frame number when the decoding is successful.

摘要： In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes receiving, by a relay node involved between a parent node and a child node, a flow control feedback message from the parent node or the child node. The communication control method includes executing, by the relay node, local rerouting to transfer a data packet to an alternative path, which is different from a path to the parent node or the child node transmitting the flow control feedback message, in response to a certain period elapsing after receiving the flow control feedback message.
