Problems solved by technology

Specifically, the BS and the UE calculate the latest SI scheduling time according to the scheduling order respectively. In order to avoid the failure of the UE to obtain the SI, the BS cannot unilaterally change the time, resulting in the inability to flexibly use the idle time and causing the UE to obtain unnecessary system information. The delay increases
[0004] Furthermore, in the prior art, the UE may not be able to accurately determine the start time of the scheduling time of non-essential system messages, resulting in the inability to obtain complete non-essential system messages

Embodiment Construction

[0050] As mentioned above, in 5G new radio (5G new radio), non-essential system messages can be provided to UEs based on specific UE requirements. However, if the BS still sends instructions to the UE according to the fixed order in the SI list after the UE puts forward the request, the delay for the UE to obtain the non-essential system information may be longer, and it may not be possible to schedule the time for the non-essential system information. The start time is accurately judged, resulting in the inability to obtain complete non-essential system messages.

[0051] The inventors of the present invention have found through research that the key to the above problem is that the UE does not directly obtain the scheduling start information from the BS, but obtains it through calculation according to the scheduling order. The BS unilaterally changes the time and easily causes the UE to fail to obtain it. The non-essential system information may update the state, and differe...

Abstract

The invention discloses a scheduling method and device of an optional system message, and a base station. The method comprises the following steps: configuring scheduling initial information in scheduling information of the optional system message, wherein the scheduling initial information is used for indicating an initial position of the most recent scheduling of the optional system message; bearing the scheduling information of the optional system message through a necessary system message sent to a user terminal, so that the user terminal can receive the optional system message according to the scheduling information. The scheme disclosed by the invention can indicate when the optional system message starts the scheduling transmission for the user terminal, thereby effectively reducing the time delay of acquiring the optional system message by the user terminal, and the complete optional system message can be acquired.

Description

technical field [0001] The present invention relates to the communication field, in particular to a scheduling method, device and base station for unnecessary system messages. Background technique [0002] In 5G new radio (5G new radio), the necessary system information (Minimum SI) is transmitted from the base station (Base Station, BS) to the user terminal (User Equipment, UE) through periodic broadcast, and the non-essential system information (on- The demand SI) can be provided to the UE based on the requirements of the specific UE, and the network can decide whether to provide the non-essential system information to the UE in a manner based on UE-specific signaling or in a broadcast manner. If the network decides to send a non-essential system message in a broadcast manner, the scheduling information of the non-essential system message is carried by a necessary system message. [0003] In the prior art, 3GPP has not discussed the scheduling process of 5G new radio non-...
