Embodiments of the present application relate to the field of data transmission, and provide a data transmission method, a communications device, a terminal, and a base station. In at least one embodiment, different configuration parameters are configured for data packets having different importance, so that an important data packet is ensured at a high priority. In at least one embodiment, a communications device is configured to determine an attribute of a data packet to be transmitted, where the attribute of the data packet is used to indicate importance of the data packet. The communications device is configured to transmit the data packet by using a configuration parameter corresponding to the attribute of the data packet.
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:
Embodiments of the present invention provide an unlicensed spectrum scheduling method which includes: monitoring, by a scheduling device, a status of a channel, and if determining by means of monitoring that the channel is idle, sending a control frame on the channel so as to reserve the channel, where a frequency domain resource occupied by the channel is in an unlicensed spectrum; sending, by the scheduling device, first channel status information to user equipment UE, where the first channel status information indicates that the scheduling device has reserved the channel; and receiving, by the scheduling device, second channel status information fed back by the UE, and determining, according to the second channel status information, whether to schedule the UE, where the second channel status information is generated by the UE according to the channel status obtained by means of monitoring.
Abstract:
Embodiments of the present invention provide a communication method and a communications device. The method includes: obtaining, by a first access network device, a first data block; performing network coding on the first data block to generate a plurality of first encoded data blocks; and performing, by the first access network device, offload processing on at least one first encoded data block in the plurality of first encoded data blocks. The offload processing includes: sending a part of the at least one first encoded data block to a second access network device, and directly sending, by using an air interface, another part of the at least one first encoded data block to the terminal device.
Abstract:
A handover apparatus and method, where the handover method includes receiving, by a target primary base station, a handover request from a source primary base station, where the handover request includes first configuration information of a source secondary base station, and the source primary base station and the source secondary base station jointly provide services for user equipment, sending, by the target primary base station, a first indication to the source secondary base station, where the first indication instructs the source secondary base station to remain unchanged, and sending, by the target primary base station, a handover acknowledgement to the source primary base station.
Abstract:
The present invention discloses a method for configuring a relay node subframe, including: a relay node (RN) sends an RN subframe configuration request for at least one component carrier (CC) to a base station, where the RN subframe configuration request for one or more CCs is used to request for RN subframe configuration for at least one CC; the RN receives the RN subframe configuration information for the at least one CC sent by the base station; and the RN subframe configuration information for the at least one CC is obtained through configuration performed by the base station after the base station receives an RN subframe configuration request for the at least one CC. The present invention also discloses a corresponding apparatus. According to a solution of the present invention, an RN subframe may be configured for a CC when carrier aggregation and RN are deployed in an integrated manner.
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.
