Abstract
Embodiments of the present disclosure provide a data transmission method a base station and user equipment. The method includes: sending by a first base station first information to a second base station or receiving by the first base station the first information sent by the second base station wherein the first information is used for indicating that the second base station is to serve user equipment; sending by the first base station second information to the user equipment wherein the second information is used for instructing the user equipment to operate on a carrier corresponding to the second base station for enabling the user equipment to operate on the carrier corresponding to the second base station. By adopting the embodiments of the present disclosure the probability of wrong scheduling of high-capacity user equipment is reduced and the performance loss caused by wrong scheduling is avoided.

Claim
1. A base station, comprising:
a receiver, configured to receive first information from a second base station after the second base station determines that a downlink semi-persistent scheduling needs to be sent to a user equipment, wherein the first information indicates that the second base station is to serve the user equipment;
a processor, configured to process the first information; and
a transmitter, configured to send second information to the user equipment according to the first information, wherein the second information is configured to instruct the user equipment to operate on a second carrier, the second carrier corresponding to the second base station;
wherein the base station is configured to interact with the user equipment via a first carrier, and to provide different functionality with respect to the user equipment relative to the second base station;
wherein the transmitter is further configured to send third information to the user equipment, wherein the third information is configured to instruct the user equipment to operate on the first carrier on a particular sub-frame and to continue to operate on the first carrier after the third information is detected; and
wherein the transmitter is further configured to send information that indicates the particular sub-frame to the second base station such that the second base station does not send data to the user equipment on the particular sub-frame, and wherein the second base station is configured to send, after k sub-frames after the first information is sent, physical downlink control channel signaling for triggering a semi-persistent service of the user equipment to the user equipment, wherein k is not smaller than 8+t, and t is an integer greater than or equal to 5.
2. The base station according to claim 1, wherein the transmitter is further configured to send the second information to the second base station.
3. The base station according to claim 1, wherein the receiver is further configured to receive fourth information from the user equipment after the user equipment determines that an uplink semi-persistent scheduling service needs to be sent to the second base station, wherein the fourth information is configured for requesting operation on the second carrier; and
wherein the transmitter is further configured to send the first information to the second base station according to the fourth information received by the receiver.
4. The base station according to claim 1, wherein the transmitter is further configured to send information that indicates the particular sub-frame to the user equipment.
5. A second base station, comprising:
