    Abstract: This application provides example sidelink control information sending methods and example communications devices. One example method includes sending, by a first communications device, first sub control information to a second communications device and a third communications device, where the first sub control information is scrambled by using a common scrambling sequence, the first communications device and the second communications device belong to a first communications device group, and the third communications device does not belong to the first communications device group. The first communications device can then send second sub control information to the second communications device, where the second sub control information is scrambled by using a scrambling sequence generated by using a user equipment identifier of the second communications device or a scrambling sequence generated by using a group identifier of the first communications device group.

    Abstract: The present disclosure discloses example power control methods and apparatuses. One example method includes determining a transmit power of a control channel and a first data subchannel, where the control channel and the first data subchannel completely overlap in time domain and do not overlap in frequency domain. A transmit power of a second data subchannel is determined to be the same as the transmit power of the control channel and the first data subchannel, where the second data subchannel and the control channel overlap in frequency domain and do not overlap in time domain. The control channel and the first data subchannel are sent to a second terminal apparatus at the transmit power of the control channel and the first data subchannel. The second data subchannel is sent to the second terminal apparatus at the transmit power of the control channel and the first data subchannel.

    Abstract: The present patent application discloses a handover method, a base station, and a terminal device. The handover method includes: sending, by a source base station, a handover request to a target base station, where the handover request includes information about a first service of a terminal device; receiving, by the source base station, a handover response sent by the target base station, where if the first service is supported by the target base station, the handover response includes information about a handover instruction for the first service, and the handover instruction is used to instruct the terminal device to hand over the first service from the source base station to the target base station; and sending, by the source base station, a handover response to the terminal device.

    Abstract: The present disclosure provide a data transmission method, including: receiving, by a central processing node, downlink user data from a first gateway GW; sending, by the central processing node, the downlink user data to a corresponding base station; and when it is determined that an interface between the central processing node and the first GW is congested, sending, by the central processing node, a first bearer switching request message to the first GW, where the first bearer switching request message is used to instruct the first GW to bypass the central processing node when transmitting data. In the embodiments of the present invention, when determining that an interface between a central processing node and a first GW is congested, the central processing node sends a first bearer switching request message to the first GW, so that the first GW transmits downlink user data with the central processing node bypassed.

    Abstract: A method for obtaining feedback delay includes: obtaining a target time elapsed in a process from when a remote radio end receives uplink data sent from a user end to when the remote radio end sends out feedback information responsive to the uplink data to the user end, wherein the feedback information responsive to the uplink data is fed back by a processing node to the remote radio end; calculating a feedback delay by adding the target time and an air interface transmission propagation delay, wherein the air interface transmission propagation delay is a transmission time of the uplink data from the user end to the remote radio end; and configuring, by the processing node, an uplink hybrid automatic repeat request (HARQ) ACK/NACK feedback interval to be the feedback delay.
