Abstract: Disclosed are a signaling optimization method and device, to resolve a problem of heavy signaling overheads and long data transmission delay when a user equipment (UE) accesses a network side. The method includes: receiving, by the UE, configuration information sent by a first network side device, where the configuration information includes a list, and the list is a cell list or a base station list; and entering, by the UE, an intermediate state according to the configuration information, where the intermediate state means that: when the UE stores context information of the UE, if the UE moves and a cell movement range falls within a coverage area of a cell or a base station included in the list, the UE performs cell reselection according to the list. Embodiments of the present disclosure are applicable to optimization of signaling transmission between the UE and a network side.

Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.

Abstract: The present application discloses methods and apparatus for resuming a radio access network (RAN) connection by an inactive terminal device. An example method disclosed herein includes the step of sending, by a terminal device, connection resumption request information to a first RAN element, where the first RAN element corresponds to the cell on which the terminal device currently camps and is a RAN element indicated by configuration information of a master cell used by the terminal device when in a connected state. The terminal device receives acknowledgement information sent by the first RAN element and resumes a connection to a second RAN element based on the acknowledgement information, where the second RAN element is a RAN element indicated by the configuration information of the secondary cell.

Abstract: Embodiments of this application disclose example data transmission methods and example devices. One example method includes receiving, by a first network device, resource configuration assistance information, where the resource configuration assistance information is used to indicate a communication pattern of user equipment. The first network device can then send dedicated resource configuration information to the user equipment based on the resource configuration assistance information, where the dedicated resource configuration information is used by the user equipment in a radio resource control (RRC) non-connected state to access the first network device, and where the RRC non-connected state is an RRC idle state or an RRC inactive state. The first network device can then perform data transmission with the user equipment by using the dedicated resource configuration information.

Abstract: The present invention relates to a scheduling request transmission method, so as to effectively transmit a scheduling request when scheduling request resources are configured on multiple carriers. The terminal receives a configuration parameter for a scheduling request from a base station; when the scheduling request is triggered, the terminal sends the scheduling request on a selected one carrier of multiple carriers according to the configuration parameter. Scheduling request resources are assigned to the terminal on multiple carriers by sending the configuration parameter, so that the terminal can send the scheduling request on the selected one carrier of the multiple carriers according to the configuration parameter. This provides a solution to effectively transmitting the scheduling request.

Abstract: A semi-persistent scheduling method includes: determining a semi-persistent scheduling (SPS) configuration parameter, where the SPS configuration parameter includes an SPS period length, symbol information, and an SPS activation command, where the SPS activation command is used to indicate a system frame number and a subframe number of a first time-frequency resource available for sending or receiving SPS data, and the symbol information is used to indicate a location of a symbol that is in a subframe and that is occupied by the first time-frequency resource; determining resource locations of time-frequency resources available for sending or receiving the SPS data based on the SPS period length, the symbol information, and the SPS activation command; and sending, by the network device, the SPS configuration parameter to a terminal device. Resource utilization of semi-persistent scheduling can be improved, and a transmission delay of the SPS data can be reduced.
