Description

Small data configuration method, device, equipment and storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for configuring small data.

Background

In the RRC (radio resource control ) Inactive state, the following features are mainly:

UE (User Equipment) will configure a dedicated paging cycle;

Mobility controlled by UE configured on the network side;

the UE stores the context of the UE AS (Access Stratum) layer;

a RAN (radio access network ) based notification domain of RRC configuration;

The UE does not perform data transmission in an inactive state.

CG (Configured Grant) Configured under Inactive is that in small data (SMALL DATA) transmission, the network side configures CG resources for the UE in the Inactive state, where the resources are consistent with the connection state configuration CG type 1.

SMALL DATA refers to: in the RRC IDLE state or the inactive state, the data size is smaller than a preset threshold value configured by a network side, or the number of data packets is smaller than the preset number of the network side. For example, the packet size is less than 30 bytes, or the number of packets is less than or equal to 5. Since the amount of transmission data is small, power consumption and data are caused if the RRC connected state is entered at this time.

The network side configures CG of the UE in RRC RELEASE information according to the content reported by the UE, wherein the CG comprises CG resource positions such as period, TBS and frequency domain time domain position; and (3) a transmission mode: such as MCS.

Detailed Description

The inventors noted during the course of the invention that:

In the process that UE performs SMALL DATA transmission in the inactive state, if the UE wants to modify the SMALL DATA transmission configuration of the UE after sending UL SMALL DATA, the network side needs to:

send RRC RELEASE a message, or;

the UE is instructed to enter the RRC connected state, and is instructed through an RRC resume or RRC reconfiguration (RRC reconfiguration) message.

It can be seen that when the small data of the UE changes, such as the data size, or the channel condition changes, the network side cannot configure the configuration authorization of the UE in the inactive state, and only can enter the RRC connection state, or send RRC RELEASE a message again to reconfigure the CG. But this introduces the problem of greater delay and signaling overhead.

Based on this, in the embodiment of the present invention, a SMALL DATA configuration scheme is provided, after the base station determines SMALL DATA resource information used by the UE, the base station sends an activated part or all of the SMALL DATA resources to the UE after receiving the data or the data request of the UE SMALL DATA; or information to reconfigure some or all of the SMALL DATA resources. Further, the UE is configured with N sets of configuration grants and/or SPS resource information in RRC RELEASE messages, where N >1. When the UE has small data transmission in the inactive state, the UE selects or informs the available configuration authorization information of the network side, and the network side indicates/activates the configuration authorization resource to transmit the small data. The following describes specific embodiments of the present invention with reference to the drawings.

And (3) a step of: after receiving the first indication information of the UE, the network side judges CG configuration of the UE in an inactive state and activates CG of the terminal.

And II: the network side sends second indication information to the UE, wherein the second indication information is used for indicating the activated CG.

The second indication information may be MAC CE, or RRC signaling, or DCI information;

the second indication information may include CG index;

Thirdly,: and after receiving the second indication information, the terminal sends feedback information to a network side, wherein the feedback information is used for feeding back that the configuration authorization has been successfully activated. The feedback information may be MAC CE or RRC signaling.

Example six:

in this example, the implementation of releasing configuration resources is described.

Whether the UE configures resources when the following condition is satisfied:

1. The timer time is satisfied;

When the network side configures configuration authorization, the UE opens a first timer, the length of the first timer is configured by the network side, and when the first timer is overtime, the UE selects RACH (Random access channel) process to execute SMALL DATA transmission or executes normal RRC establishment process to complete data transmission;

2. More than M times resources have no data transmission;

after the network side configures the configuration grant, if the UE does not send UL (uplink) data on consecutive M configuration grant resources, the UE will release the configuration grant, M being configured by the network side.

3. After K times of transmission;

After the UE completes K configuration grant transmissions, K may be configured by the network side, and when the UE still has UL data to transmit after K transmissions are reached, the UE enters a normal RRC establishment procedure to complete subsequent data.
