Abstract: A first access network device receives an addition request message from a second access network device. The first access network device determines a third uplink carrier used by a terminal to send a preamble to the first access network device, and sends an addition request acknowledgement message to the second access network device. The addition request acknowledgement message includes carrier indication information. The carrier indication information indicates the third uplink carrier. The third uplink carrier is at least one of the first uplink carrier or a second uplink carrier. The second uplink carrier and the first uplink carrier belong to a same cell of the first access network device and the second uplink carrier is a supplementary uplink carrier.

Abstract: The present invention provides a information processing method at a terminal or a base station. The method at the terminal includes: receiving scheduling information of a physical downlink shared channel (PDSCH) carrying system information, the scheduling information of the PDSCH carried in a master information block (MIB) or downlink control information on an enhanced physical downlink control channel (EPDCCH) sent from the base station, wherein the scheduling information of the PDSCH is used for determining at least one kind of transmission information of the PDSCH; determining the transmission information of the PDSCH according to the scheduling information of the PDSCH. In this way, an extra overhead of a control instruction when a PDCCH is used to schedule a SIB in the prior art is reduced.

Abstract: A mobility load balance processing method includes: sending, by a donor base station DBS, indication information to a relay node RN of the donor base station DBS, where the donor base station DBS uses the indication information to instruct the relay node RN to perform mobility load balance processing to hand over at least one user equipment UE in a cell of the relay node RN to a neighboring cell. A relay node, a donor base station, and a communication apparatus are also disclosed. Through UE handover, a cell to which a UE is attached can be adjusted, so that load balance between cells is achieved after an RN is introduced. In this way, network resource utilization is maximized, and system capacity and system performance are improved.
