System information processing method, system information acquisition method, system information processing device and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a system information processing method, an acquiring method, an apparatus, and a terminal.

Background

The traditional wireless communication adopts a cellular network communication mode, namely, a terminal and network side equipment transmit uplink and downlink data or control information through a Uu interface.

Direct communication refers to the manner in which nearby terminals can communicate data over a direct communication link (also known as a sidlink or PC 5) within a close range. The wireless interface to which the sidlink link corresponds is referred to as a direct communication interface (also referred to as a sidlink interface or PC5 interface).

To extend network coverage, L2 relay is introduced. The L2 relay itself may be a terminal having a relay function. For terminal-to-Network Relay (UE-to-Network Relay), the interface between the L2 Relay and the Network uses Uu interface, and the interface between the far-end terminals uses direct communication interface. The link between the L2 relay and the network may be referred to as a Backhaul link (Backhaul link) for the far-end terminal.

In an L2 relay scenario in a long term evolution (Long Term Evolution, LTE) system, the system information acquisition mode of the remote terminal is as follows:

the network may configure whether the relay terminal allows forwarding the system message to the remote terminal. If the relay terminal allows forwarding the system message to the remote terminal, the relay terminal may forward the main system information block (MasterInformationBlock, MIB), the system information block1 (SIB 1) and the SIB1 related to direct communication to the remote terminal through broadcasting or multicasting after receiving the system message at the Uu interface.

For 5G and future mobile communication systems, other system messages may be sent on-demand (on-demand) in addition to MIB or SIB 1. Therefore, the system message direct forwarding method of the existing LTE L2 relay system is not applicable to 5G and future relay communication systems.
