Method and device for activating configuration in LTE system

Abstract

The embodiment of the invention relates to a method for activating configuration in an LTE system in the field of communication, which comprises the following steps of: constructing activation or deactivation information and carrying the activation or deactivation information in downlink physical control channel (PDCCH) signaling; and sending the PDCCH signaling to user equipment through a PDCCH so as to make the user equipment correspondingly activate or deactivate the configuration according to the activation or deactivation information in the PDCCH signaling. The embodiment of the invention also provides a device for activating the configuration. In the embodiment of the invention, the user equipment is informed to activate or deactivate the corresponding configuration through the downlink physical control channel signaling, so that a network side and the user equipment can synchronously activate / deactivate the corresponding configuration, not only uplink resources can be saved, but also uplink interference among different user equipment can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for activating configuration in an LTE system. Background technique [0002] Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic Repeat Request) technology is an error correction method that combines automatic repeat request (ARQ, automatic repeat request) and forward error correction. The code sent by the sending end can not only detect errors, but also have certain error correction capabilities. After receiving the code word, the decoder at the receiving end first checks the error situation. If it is within the error correction capability of the code, it will automatically correct the error. If the number of errors exceeds the error correction capability, the receiving end will send a message to the sending end through the feedback channel. Judgment signal, requesting the sender to resend. [0003] The HARQ system is to introduce a for...

Problems solved by technology

[0010] Since the LTE system cannot specify the activation / deactivation time, the eNB cannot know exactly when the UE activates / deactivates the TTI Bundling configuration, that is, the TTI Bundling activation / deactivation of the eNB and the UE cannot be completely synchronized; and the TTI Bundling The timing of feedback and retransmission is different from that of ordinary uplink HARQ. If the activation / deactivation of TTI Bundling is not synchronized, it will not only cause the loss of uplink data frames or waste of uplink resources, but also may cause mutual interference between UEs, resulting in other The HARQ process transmission of multiple UEs fails
