Abstract: Embodiments of the present invention provide a power headroom report reporting method and an apparatus. The power headroom report reporting method in the present invention includes: receiving, by user equipment, power headroom report PHR level information sent by a base station; determining, by the user equipment based on the PHR level information, a PHR corresponding to the PHR level information; and sending, by the user equipment, the PHR corresponding to the PHR level information to the base station. In the embodiments of the present invention, the base station can obtain PH of the UE at a corresponding level based on a scheduling requirement, and further perform proper scheduling on the UE based on a PHR.

Abstract: A reference signal transmission method and a related device and system are disclosed. The method includes: determining, by a first base station, at least one target subframe on a target frequency band, where the target frequency band is a frequency band whose uplink and downlink transmission directions are configurable, and uplink-downlink timeslot configurations and/or transmission directions of the first base station and a neighboring second base station in the at least one target subframe are different; and sending, by the first base station, a first reference signal to first user equipment UE in the at least one target subframe, where the first UE is UE served by the first base station. When embodiments of the present invention are implemented, a reference signal can be transmitted on a flexible frequency band, thereby effectively reducing interference between reference signals between neighboring cells in a flexible duplex system.

Abstract: Example handover methods and devices in an ultra-dense network are disclosed. One example method includes the following operations. A source base station sends a first message to a target base station, where the first message carries an arrival time indication of a terminal, and the arrival time indication is used to indicate a time at which or a time range in which the terminal is to access the target base station. The source base station receives a second message fed back by the target base station, where the second message carries a granted resource that is allocated for the arrival time indication of the terminal. The source base station adds the granted resource to a command message, and sends the command message to the terminal.

Abstract: A sending node sends an RTS control packet carrying an identifier of a receiving node, so that the receiving node determines a power update value according to an initial transmit power of the RTS control packet and sends a CTS control packet by using the initial transmit power, where the CTS control packet carries an identifier of the sending node and the power update value, a first part of adjacent nodes other than the sending node, if determining that the first part of adjacent nodes are located beyond coverage of an updated power of the receiving node and the sending node, determine a first limited power and perform control packet transmission according to the first limited power; and receiving, by the sending node, the CTS control packet, and sending a data packet by using the updated power.
