    Abstract: Embodiments of the present disclosure provide a method. According to the method, a mark is added to a data packet. After user equipment is handed over from an original device to a target device, and before a user plane network element receives a handover notification, the user plane network element sends, through a path used before handover, a data packet that carries a first mark to the original device. The original device modifies the first mark in the data packet to a second mark, and then forwards, to the target device, a data packet whose mark is modified and that carries the second mark. After receiving the handover notification, the user plane network element sends, to the target device, a data packet that carries a fourth mark. The target device can distinguish between sources of the received data packets based on different marks in the received data packets.

    Abstract: A signal sending method, a signal receiving method, and an apparatus are provided. The method includes: generating, by a terminal device, a first symbol group that carries a first preamble, where the first symbol group includes four groups of symbols; and sending, by the terminal device, the first symbol group to a network device in K groups of uplink subframes, where any two groups of uplink subframes in the K groups of uplink subframes are not adjacent, each group of uplink subframes in the K groups of uplink subframes include at least one uplink subframe, and uplink subframes included in the group of uplink subframes are continuous subframes, where K is a positive integer greater than 1 and less than or equal to 4.

    Abstract: Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

    Abstract: Embodiments of the present invention provide a reference signal sending method, a reference signal receiving method, and an apparatus. A reference signal sending method includes: obtaining a reference signal sequence, where the reference signal sequence includes multiple bits and exclusive OR of every two bits separated by one bit in the multiple bits is 1; performing Gaussian Minimum Shift Keying GMSK modulation on the reference signal sequence; and sending a modulated reference signal sequence. In the embodiments of the present invention, a reference signal sequence is designed as a sequence in which exclusive OR of every two bits separated by one bit is 1, GMSK modulation is performed on the reference signal sequence, and the same reference signal sequence is used to perform channel estimation during GMSK demodulation. Compared with a case in which a pseudo random sequence is used as a pilot symbol, channel estimation accuracy is improved.

    Abstract: Embodiments of the present application disclose a random access method, a base station, and a terminal device. The terminal device receives random access configuration information from a base station, and determines a random access channel, a base frequency, and at least two frequency hopping intervals according to the random access configuration information. The terminal device sends, over the random access channel, random access signals to the base station using frequencies determined according to the base frequency and the N frequency hopping intervals. The terminal device may send the random access signals over the random access channel to the base station according to the base frequency the frequency hopping intervals and a frequency hopping pattern.

    Abstract: Embodiments of the present invention provide an information sending method, including: determining, by a base station, first information indicating a first carrier frequency offset, where the first carrier frequency offset is a carrier frequency offset between an actual cell carrier center frequency and a cell carrier center frequency that is obtained by a terminal; and sending, by the base station, the first information to the terminal, where the first information is used to obtain the actual cell carrier center frequency. According to the technical solutions provided in the embodiments of the present invention, quality of communication between the terminal and the base station is effectively improved.
