Problems solved by technology

[0003] In the process of realizing the transmission of the above multi-subframe scheduling signaling, if the eNB wrongly detects the ACK / NAK sent by the UE, that is, wrongly detects the ACK as a NAK or wrongly detects the NAK as an ACK, which will cause all The process of receiving and processing by the UE is inconsistent with the process sent by the eNB, resulting in process error transmission, and if the eNB and the UE continue to communicate, the wrong process will continue to be transmitted, which will affect the correct transmission of scheduling information

Abstract

The invention discloses a method and a device for transmission of multiple subframe scheduling signaling and relates to the technical field of wireless communication. Correct transmission of the scheduling signaling is guaranteed. The method for the transmission of the multiple subframe scheduling signaling includes the steps: acquiring a first corresponding relationship and confirming a plurality of hybrid automatic repeat request (HARQ) processes according to the first corresponding relationship, wherein the first corresponding relationship is the corresponding relationship between process numbers of the plurality of HARQ processes and process fields of the HARQ processes; generating the scheduling signaling according to the first corresponding relationship and the plurality of HARQ processes; and enabling the scheduling signaling and data packages which corresponds with the plurality of HARQ processes scheduled by the scheduling signaling to be sent to devices of users. The method and the device for the transmission of multiple subframe scheduling signaling are mainly used in the process of the transmission of the multiple subframe scheduling signaling.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting multi-subframe scheduling signaling. Background technique [0002] Currently, in the LTE (Long Term Evolution, long-term evolution) system, the base station (eNB) uses one scheduling signaling to schedule the user equipment (UE) with a minimum time interval of one subframe, and one scheduling signaling can only schedule one subframe scheduling information. In the subsequent evolved version of the LTE system, one scheduling signaling can schedule the scheduling information of multiple subframes, and the eNB will feedback the HARQ (Hybrid Automatic Repeat reQuest, Hybrid Automatic Repeat Request) reception status fed back by the UE (when the reception is correct, feedback ACK (Acknowledgment, confirmation character); when receiving an error, feed back NAK (NegativeAcknowledgment, denial character)) and HPN (HARQ Process N...
