Technical field

Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

A new RRC state is defined in the New Radio (NR) network: RRCINACTIVE (RRC inactive state). The network equipment in the radio access network can send an RRCelease message carrying the SuspendConfig IE to a user terminal (UE) in the RRC Connected state (RRC connected state) to indicate that it enters the RRC inactive state. If the small data transmission is allowed when the UE is in the RRC inactive state, the UE will be prevented from frequently entering the RRC connected state, and the signaling overhead can be reduced. However, for the small data transmission in the inactive state, in the prior art, competitive random access is used to realize the small data transmission in the RRC inactive state. However, due to the competition, there may be competition failures that do not meet the requirements of QoS. Therefore, each of the present disclosures The embodiment provides a solution for small data transmission in an RRC inactive state, by which a UE can implement small data transmission in an RRC inactive state using a non-contention random access process.

The core idea of each embodiment of the present disclosure is that the network sends instruction information to the terminal to instruct the terminal to enter the RRC inactive state, and the instruction information carries special configuration information for non-competitive random access. When the terminal has a small data transmission requirement in the inactive state, it can initiate random access based on the non-competitive random access dedicated configuration information, and transmit the small data through the non-competitive random access process. The present disclosure will be described in detail below in conjunction with a number of embodiments.

Fig. 1 is a schematic flow chart of a data transmission processing method provided by an embodiment of the present disclosure. As shown in Fig. 1, the method includes the following steps:

Step 100: Receive first indication information sent by the network, and enter the RRC inactive state according to the first indication information; wherein, the first indication information carries dedicated configuration information for non-competitive random access;

Specifically, in the embodiments of the present disclosure, when the terminal has no data transmission requirement on the Uu interface, the network device in the radio access network may send an indication message to the UE in the RRC connected state to instruct it to enter the RRC inactive state.

In the embodiment of the present disclosure, the network device may send the first indication information to the UE. After receiving the first indication information sent by the network device, the UE may enter the RRC inactive state according to the first indication information, for example, the UE The RRC connected state can be changed from the previous RRC connected state to the RRC inactive state. At the same time, the first indication information carries special configuration information for non-contention random access, which aims to prevent the UE in the RRC inactive state from entering the RRC connection state when there is a small data transmission requirement, thereby increasing signaling overhead.

Step 101: When there is a data transmission demand in the RRC inactive state, initiate a random access process based on the non-competitive random access dedicated configuration information, and transmit data through the random access process.

After the UE enters the RRC inactive state according to the first indication information sent by the network device, if the UE needs to send data, that is, when the UE has a data transmission requirement in the RRC inactive state, it can be based on the first indication information The carried non-competitive random access dedicated configuration information initiates a random access process to the network, and sends the data that needs to be sent to the network during the random access process.

The embodiments of the present disclosure are described by taking the UE's need to send small data as an example. Of course, those skilled in the art can know that the technical solutions of the embodiments of the present disclosure are not limited to small data sending scenarios, and other data types can also be sent. Be applicable. For the convenience of subsequent discussion, each embodiment of the present disclosure only uses small data as an example for introduction. The so-called small data, as the name implies, is data with a relatively small amount of data. For example, the data corresponds to only one IP packet, and the size of the IP packet is only a few bytes or more than a dozen bytes.

According to the data transmission processing method provided by the embodiments of the present disclosure, the terminal can enter the RRC inactive state after receiving the instruction information sent by the network, and in the RRC inactive state, the random access process initiated by the non-competitive random access dedicated configuration information Perform data transmission to prevent the terminal from entering the RRC connection state due to small data transmission, thereby reducing signaling overhead and better meeting service delay requirements.

Specifically, the resources used by the non-competitive random access may be two-step non-competitive random access resources and/or four-step non-competitive random access resources. Specifically, the non-competitive random access resources can be configured according to the non-competitive random access dedicated configuration. According to the information, the UE can obtain the two-step non-contention random access resource and/or the four-step non-competition random access resource according to the dedicated configuration information for the non-contention random access. The non-contention random access dedicated configuration information carried in the first indication information will specifically indicate the non-competition random access resources used by the UE for non-contention random access, such as PRACH (Physical Random Access Channel) resources . When the non-competitive random access dedicated configuration information only includes two-step non-competitive random access dedicated configuration information, the UE can initiate a two-step non-competitive random access procedure; when the non-competitive random access dedicated configuration information only includes Four-step non-contention random access dedicated configuration information, the UE can initiate a four-step non-contention random access process; when the non-contention random access dedicated configuration information includes two non-contention random access dedicated configuration information and four steps When non-contention random access dedicated configuration information, the UE can either initiate a two-step non-competition random access process or a four-step non-competition random access process, but it needs to choose one to proceed, and which random access process is specifically selected.

Principle 3: If the amount of data corresponding to the data is greater than the amount of data that can be carried by the two-step non-contention random access PUSCH, then a four-step non-competition random access process is initiated based on the dedicated configuration information for the four-step non-competition random access; Otherwise, a two-step non-contention random access procedure is initiated based on the two-step non-contention random access dedicated configuration information.

On the basis of the foregoing embodiments, the UE transmitting data through the random access procedure may include the following steps:
