    摘要: Methods and a wireless communication device for carrying out beam failure recovery include, according to various implementations, using a beam failure recovery request media access control-control element (BFRR MAC CE) to transfer beam failure recovery information (e.g., from one node of a wireless network to another—such as from a mobile wireless communication device to a base station (BS)). The BFRR MAC CE may include one or more of: the reference signal (RS) type (i.e., the type of RS resource), the identity of the RS resource, the identity of a frequency location (e.g., the identity of a bandwidth part in cases where bandwidth part (BWP) is used), and the identity of the serving cell.

    摘要: A method for implementing access stratum security is provided. The method includes: performing end-to-end user plane access stratum security between a UE and a gateway node; and performing end-to-end control plane access stratum security between the UE and an initial access node when the UE only has a micro communication path; when the UE has the micro communication path and a macro communication path, performing end-to-end control plane access stratum security between the UE and a macro base station in the macro communication path. The micro communication path is a communication path in which the UE accesses a small radio access node via a radio access link and then accesses a core network finally. The macro communication path is a communication path in which the UE accesses the macro base station via the radio access link and then accesses the core network finally.

    摘要: Provided are a handover method and apparatus. The method includes following steps: a UE receives an RRC reconfiguration message sent by a source base station, where the RRC reconfiguration message includes a list of target cells for performing a conditional handover by the UE, information of each target cell in the list of the target cells for performing the conditional handover includes at least one of the following: frequency information of the target cell, a physical cell identifier of the target cell, a conditional handover command of the target cell generated by the target cell, or at least one piece of measurement configuration identifier information, and the at least one piece of measurement configuration identifier information is used for instructing an execution condition for the UE to perform a conditional handover in the target cell; and the UE performs a handover according to the RRC reconfiguration message.

    摘要: 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.
