Embodiment Construction

[0124] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0125]In related technologies, both the base station and the UE can support multi-carrier transmission. But no matter which carrier the base station transmits data on, the UE may fail to receive it. At this time, a hybrid automatic retransmission (HARQ) technology may be used, and the base station resends data that fails to be received to the UE. However, the base station retransmits on the or...

Abstract

The present invention relates to a method and apparatus for hybrid automatic retransmission. The method includes: after receiving the failure indication information indicating that the downlink data transmission fails, sent by the user equipment, on the first carrier of the multiple carrier, generating a retransmission scheduling instruction; sending the heavy weight to the UE on the second carrier And transmitting the scheduling instruction; the retransmission scheduling instruction includes retransmission indication information about retransmission on the third carrier; the first carrier andthe second carrier are the same carrier or different carriers; the second carrier and the third carrier Is the same carrier or different carriers; the first carrier and the third carrier are different carriers. In the present invention, the first transmission data and the retransmission data may not be on the same carrier, and the cross-carrier hybrid self-retransmission is realized by schedulingthe retransmission scheduling instruction.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a hybrid automatic retransmission method and device. Background technique [0002] In the related art, with the improvement of hardware performance of user equipment (UE), UE can support multi-carrier transmission. No matter on which carrier the base station transmits data, the UE may fail to receive it. At this time, a hybrid automatic retransmission (HARQ) technology may be used, and the base station resends data that fails to be received to the UE. However, at present, data transmission and retransmission are performed on the same carrier. There is currently no effective solution support for the cross-carrier retransmission mechanism. Contents of the invention [0003] Embodiments of the present invention provide a hybrid automatic retransmission method and device. Described technical scheme is as follows: [0004] According to the first aspect of the emb...
