Problems solved by technology

[0005] However, for 5G NR V2X, the logical channel is configured by the network. If the correlation between the logical channel parameters corresponding to the two radio bearer RBs used for repeated transmission is still fixed, the allocation of logical channels will be less flexible. The interface must reserve a part of logical channels dedicated to repeated transmission, resulting in low utilization of logical channels

Embodiment 1

[0055] Embodiment 1. The method for repeated transmission of a direct communication interface provided in this embodiment can be applied to a system for repeated transmission of a direct communication interface. The system includes a terminal and a network-side device. The following direct communication is performed on the system The implementation steps of the terminal and the network side device when the interface is repeatedly transmitted are described:

[0056] like Figure 4 As shown, the system includes a terminal 400 and a network side device 401, wherein:

[0057] The network side device 401 is configured to configure repeated transmission configuration information of the direct communication interface for the terminal; send explicit indication information or implicit indication information to the terminal, and determine the direct communication interface through the explicit indication information or implicit indication information. The radio bearer of the communicat...

Embodiment 2

[0160] Embodiment 2, the first method for repeated transmission of the direct communication interface of the terminal in the RRC connection state.

[0161] like Figure 5 As shown, the implementation process is as follows:

[0162] In step 500, the terminal determines that the auxiliary information reporting condition for repeated transmission activation or repeated transmission deactivation is met.

[0163] Step 501, the terminal reports auxiliary information to the network side device to assist the network side device to determine whether to activate or deactivate the radio bearer.

[0164] Wherein, steps 500 and 501 are optional steps.

[0165] Step 502, the network side device receives the auxiliary information reported by the terminal to determine whether to activate or deactivate the radio bearer.

[0166] Optionally, the network side device may independently determine to activate or deactivate the radio bearer.

[0167] Step 503: For the terminal in the RRC connecti...

Embodiment 3

[0169] Embodiment 3, the second method for repeated transmission of the direct communication interface of the terminal in the RRC connection state.

[0170] like Image 6 As shown, the implementation process is as follows:

[0171] Step 600: For a terminal in the RRC connection state, the network side device configures the repeated transmission configuration information for the radio bearer of the direct communication interface of the terminal through RRC layer dedicated signaling.

[0172] In step 601, the terminal determines that the auxiliary information reporting condition for repeated transmission activation or repeated transmission deactivation is satisfied.

[0173] Step 602, the terminal reports auxiliary information to the network side device to assist the network side device to determine whether to activate or deactivate the radio bearer.

[0174] Wherein, steps 601 and 602 are optional steps.

[0175] Step 603, the network side device receives the auxiliary infor...

Abstract

The invention discloses a direct communication interface repeat transmission method, a terminal and network side equipment, which are used for providing a more flexible direct communication interfacerepeat transmission mechanism. The method comprises the following steps that a terminal acquires the repeated transmission configuration information of a direct communication interface; and the terminal receives the explicit indication information or implicit indication information sent by network side equipment, and determines whether the radio bearer of the direct communication interface is activated or deactivated for repeated transmission through the explicit indication information or the implicit indication information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for repeated transmission of a direct communication interface, a terminal and a network side device. Background technique [0002] The 5G New Radio (NR) system mainly supports three types of services: enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC), ultra-reliable and low-latency communications (Ultra-Reliable and Low Latency Communications, URLLC); [0003] In order to support vertical applications in the industry, NR Vehicle to Everything (V2X) is introduced. In order to improve the reliability of V2X message transmission and reduce the delay, it can support repeated transmission. For example, the current URLLC service introduces a repeated transmission mechanism, which transmits the same PDCP layer PDU through multiple paths, improves transmission reliability through multiple transmission gains, and reduces transmis...
