AI Technical Summary

Technical Problem

Existing technologies lack effective MBMS data reception feedback schemes, especially after the introduction of ARQ mechanism at the RLC layer, which increases system complexity and RRC signaling overhead.

Method used

The introduction of the HARQ mechanism at the MAC layer enables feedback and retransmission of MBMS data through the HARQ process, which simplifies the protocol stack functions, reduces feedback latency, and reduces RRC signaling overhead.

Benefits of technology

It enables fast and efficient feedback of MBMS data, reduces system complexity and RRC signaling overhead, and ensures the accuracy and flexibility of feedback.

Abstract

The application discloses an information configuration method and device, a terminal, a network device and a storage medium. The method comprises the following steps: receiving radio resource control (RRC) signaling sent by a network side, wherein the RRC signaling carries at least one hybrid automatic repeat request (HARQ) process related information; at least one HARQ process in the at least one HARQ process is for a multicast channel (MCH); and the related information of the at least one HARQ process for the MCH comprises at least one of the following: the identification of the HARQ process; the identification of the HARQ process and the time offset of the uplink feedback corresponding to the HARQ process; the process mode of the HARQ process; the buffer size of the HARQ process; the feedback mode of the HARQ process; whether the function body of the HARQ process is an independent function body; and the resource used when the HARQ process transmits data and / or feedback.
