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.

Abstract: A measurement method, a cell measurement method, an apparatus, and a communications node are disclosed. A first communications node sends measurement information to a second communications node, where the measurement information includes measurement signal configuration information and/or configuration information of a measurement signal combination, the two pieces of configuration information are respectively used by the second communications node to determine a resource of a measurement signal corresponding to the measurement signal configuration information and a resource of a measurement signal corresponding to the configuration information of the measurement signal combination; and the first communications node receives a measurement report sent by the second communications node, where the measurement report carries a measurement result of measurement performed by the second communications node according to the measurement information. The examples of the present invention implement measurement on a radio link after introduction of a non-backward-compatible cell or carrier.

Abstract: The embodiments of the present invention provide a base station, a network controller, and a forward handover method. The base station includes a first base station to which a target cell of user equipment belongs and a second base station to which the user equipment belongs, where the second base station includes: a second processor and a second transceiver, the second processor generates a forward handover indication, and the second transceiver sends the forward handover indication to the first base station, so that when receiving an RRC re-establishment request message of the user equipment, the first base station acquires context information of the user equipment from the second base station according to the forward handover indication. In the foregoing manner, the user equipment can independently select a target cell, and overcomes a disadvantage of violating a basic criterion in the prior art that mobility management is determined and controlled by a network.

Abstract: Embodiments of the present disclosure disclose a message broadcast method, a base station, and user equipment. The message broadcast method includes: determining, by a base station, a piece of system subgroup information of system information of a first cell, where each piece of system subgroup information includes system information content that is applied to a user equipment group that corresponds to the system subgroup information. The method also includes broadcasting, to the user equipment group, the system subgroup information that corresponds to the user equipment group. In such a manner, system information that is generated due to a requirement of a new technology can be effectively reduced, and user equipment can be prevented from receiving information unrelated to the user equipment and triggering unnecessary behavior.

Abstract: The present invention provides a wireless access point control method, a related device, and a system. An activation signal sent by user equipment is received on a radio resource corresponding to a receiving pattern of a first wireless access point, so that the first wireless access point controls itself to leave a power-saving state according to the activation signal. Therefore, the user equipment may directly send the activation signal to the first wireless access point to switch a working state of the first wireless access point from the power-saving state to a normal communication state as soon as possible. In this manner, a power-saving objective of the wireless access point is achieved, and switching of the wireless access point from the power-saving state to the normal communication state as soon as possible can also be accelerated on a basis of achieving power saving of the wireless access point.

Abstract: In a cell handover method and system, after receiving a pre-handover instruction sent by a first eNB, a random access preamble is sent by the UE, and a radio bearer corresponding to a second eNB is established by the UE, according to configuration information in the pre-handover instruction. The UE receives a timing advance that is usable by the UE in performing uplink synchronization with the second eNB and an uplink indication message that indicates an uplink resource that is usable by the UE in communications with the second eNB.

Abstract: The present disclosure discloses a method, a device and a system for uplink resource allocation, relating to a wireless communication field and used for further reducing interference of service transmission between cell uplinks. The method for uplink resource allocation includes: a first base station determines uplink almost blank subframe (UL ABS) subframe(s) unused currently of a user equipment (UE) served by the first base station; and the first base station sends information of the determined UL ABS subframe(s) unused currently of the UE served by the first base station to a second base station, so that the second base station acquires available UL ABS subframe(s) and takes the available UL ABS subframe(s) as uplink subframe resource(s) of the second base station. The present disclosure is applied to a resource allocation scenario.
