Abstract: The present invention discloses a carrier configuration method and a device, and relates to the field of communications, to resolve a problem that dividing multiple component carriers into primary and secondary component carriers only is not conducive to management of an important secondary component carrier. In a specific solution, a carrier aggregation model is configured for UE, so that the UE performs data transmission with a network device according to the carrier aggregation model. The carrier aggregation model includes multiple component carriers, the multiple component carriers include at least one core carrier, and the at least one core carrier includes at least one primary core carrier. The core carrier has an uplink transmission function and a downlink transmission function. The present invention is applied to a carrier configuration process.

Abstract: The present disclosure provides a communication method, a network-side device, and user equipment. The method includes: receiving, by a network-side device, a radio resource control RRC connection reestablishment request message, where the RRC connection reestablishment request message is used to request to perform RRC connection reestablishment; and sending, by the network-side device, an RRC connection reestablishment indication message, where the RRC connection reestablishment indication message carries a configuration parameter, and the configuration parameter includes at least one of a signaling radio bearer SRB2 configuration parameter or a data radio bearer DRB configuration parameter. The network-side device sends only the RRC connection reestablishment indication message, thereby effectively reducing a reestablishment delay and physical resource overheads.

Abstract: Embodiments of the present invention disclose a random access method and an apparatus. According to the random access method disclosed in the embodiments, first downlink assignment information is obtained in a manner of a mapping relationship between first downlink assignment information and a preamble, where the first downlink assignment information is downlink assignment information used by a random access response message, and scheduling signaling of the random access response message does not need to be retransmitted by using the PDCCH channel, thereby resolving problems of a channel resource waste and an access delay in an existing random access method. The problems are caused because the PDCCH channel is used to retransmit the scheduling signaling of the random access response message.

Abstract: Embodiments of the present disclosure provide a method and a communications system for switching a transmission time interval, user equipment, and an evolved NodeB (eNB). User equipment (UE) calculates a transmission time interval (TTI) switching characteristic parameter, and the UE sends a TTI switching request message if the TTI switching characteristic parameter meets a switching condition. The eNB sends, to the UE, a TTI switching indication message that includes indication information of a second TTI, and the UE performs transmission by using the second TTI. By using the method for switching a TTI, the UE and the eNB described in the embodiments of the present disclosure, a TTI used for transmission can be adjusted in time according to a channel quality change of the UE, thereby remarkably shortening a service delay.

Abstract: A method, an apparatus, and a system for collecting information about a wireless local area network (WLAN) access point (AP). The method specifically includes: a user equipment (UE) receives WLAN AP request information from a base station in a Minimization of Drive Tests (MDT) measurement configuration process, collects WLAN AP information according to the WLAN AP request information, and sends the WLAN AP information to the base station, wherein the WLAN AP request information is used to request the UE to report WLAN AP information. By using an MDT measurement configuration process, a UE may collect and report WLAN AP information based on architecture of a mobile communications network. In this way, WLAN AP information can be conveniently collected.
