Embodiment Construction

[0105] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0106] like Figure 4 As shown, an embodiment of the present invention provides a method for activating / deactivating repeated transmission, which is applied to a first base station, where the first base station is connected to a terminal, and the method includes:

[0107] Step 41: Determine the correspondence between the bearer that allows repeated transmission under the first base station and the bits of the preset field of the medium access control layer control message MAC CE of the activation / deactivation of the first base station; the preset The field is used to indicate the activation / deactivation of repeated transmissions for bearers that allow repeated transmissions.

[0108] In this step, the preset field is specifically the...

Abstract

The present invention provides a repeated transmission activation / deactivation method, base station, terminal and device. The method includes: determining the bearer allowed for repeated transmission under the first base station and the activation / deactivation of the first base station for repeated transmission medium access Correspondence between the bits of the preset field of the control layer control message MAC CE; when it is necessary to activate / deactivate the repeated transmission of the bearer that allows repeated transmission under the first base station, the first base station will activate / deactivate the repeated transmission In the preset field of the MAC CE, the bits corresponding to the bearer are filled and set, and the activation / deactivation repeated transmission MAC CE is generated and sent to the terminal; in the embodiment of the present invention, when the terminal is connected to multiple base stations , can correctly receive and realize the repeated transmission activation / deactivation of different types of bearers, so as to effectively realize the repeated transmission, and avoid the problem of operation errors caused by misunderstandings on the network side and the terminal side.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, base station, terminal and device for activating / deactivating repeated transmission. Background technique [0002] The 5G NR (New Radio) system mainly supports three types of services: eMBB (enhanced MobileBroadband, enhanced broadband communications); mMTC (massive Machine Type Communications, massive machine type communications); URLLC (Ultra-Reliable and Low Latency Communications, high reliable low-latency communication). [0003] For URLLC, due to its relatively high requirements on delay and reliability, a solution provided by 3GPP is to introduce a repeated transmission mechanism, that is, to transmit the same PDCP (Packet Data Convergence Protocol) through multiple paths. Protocol) layer PDU (Protocol Data Unit, Protocol Data Unit), improve transmission reliability through multiplexing gain, and reduce transmission delay. After the introd...
