To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

The pre-configured resources adopt a pre-configured or semi-persistent resource configuration method, and the terminal device can transmit services on the pre-configured resources according to service requirements. The pre-configured resources avoid the resource request (SR, Schedule request) and the buffer status report (Buffer Status Report, BSR) process, and increase the effective transmission time of the terminal device.

There are two ways to configure pre-configured resources, type 1 and type 2. Among them, type1 uses radio resource control (Radio Resource Control, RRC) signaling to configure pre-configured resources. Among them, RRC signaling is used for semi-static configuration, and the content of RRC signaling configuration includes at least time domain resources, frequency domain resources, and reference symbols Information, modulation and coding method and power control parameters. Type2 uses a combination of RRC signaling and physical layer signaling to configure pre-configured resources. Among them, RRC signaling is used for semi-static configuration, physical layer signaling is used for dynamic activation or deactivation, and the content of RRC signaling configuration includes at least time domain resources. , Period and power control parameters, and the content of the physical layer signaling configuration includes at least frequency domain resources, reference symbol information, and modulation and coding methods.

In the above-mentioned type 1 and type 2 resource configuration methods, the resources are configured semi-statically or semi-continuously, but service requirements (such as Transport Block Size (TBS), Modulation and Coding Scheme, MCS) ) Is dynamic. Therefore, multiple pre-configured resources need to be configured to adapt to different services.

In addition, in order to ensure the reliable transmission of services, repeated transmissions are also introduced. However, since the starting point of repeated transmission is flexible, the end point is certain. The above scheme cannot guarantee that the number of repetitions meets the preset value. Therefore, it is considered to configure multiple pre-configured resources to adapt to different starting points, so as to adapt to services that come at any time, and to ensure multiple repeated transmissions.

Configuring a pre-configured resource requires one DCI. Correspondingly, configuring multiple pre-configured resources requires multiple DCIs. The downlink control signaling overhead increases and may even cause PDCCH congestion. A resource configuration method suitable for semi-persistent transmission needs to be considered. Reduce signaling overhead. In addition, when multiple terminal devices multiplex pre-configured resources, if DCI format 0_0 is used to activate the pre-configured resources, since the high-level configuration signaling and DCI activation signaling of the pre-configured resources do not include demodulation pilot (Demodulation Reference Signal, DMRS) configuration information, the terminal device will use the default or preset DMRS configuration. When multiple terminal devices share the time-frequency resource of the pre-configured resource, the same DMRS configuration will cause demodulation failure, thereby affecting the reliability of data transmission. To this end, the following technical solutions of the embodiments of the present application are proposed.

FIG. 2 is a schematic flowchart of a resource configuration method provided by an embodiment of the application. As shown in FIG. 2, the resource configuration method includes the following steps:

Step 201: The terminal device receives the first signaling and the second signaling; where the first signaling includes configuration information of at least one pre-configured resource, wherein the configuration information of the at least one pre-configured resource includes at least demodulation Pilot information; the second signaling is used to activate or deactivate one or more pre-configured resources in the at least one pre-configured resource.

Specifically, the network device sends the first signaling and the second signaling, and correspondingly, the terminal device receives the first signaling and the second signaling sent by the network device. In an embodiment, the network device is a base station, such as a gNB.

In an optional implementation manner of the present application, the first signaling is high-layer signaling. For example: the first signaling is RRC signaling.

In an optional implementation manner of the present application, the second signaling is physical layer signaling. For example: the second signaling is DCI.

In the embodiment of the present application, the first signaling includes configuration information of at least one pre-configured resource. Here, the pre-configured resource may also be referred to as a configured grant. To configure the at least one pre-configured resource through the first signaling, any one of the following methods may be adopted:

Manner 1: The first signaling includes configuration information of the at least one pre-configured resource.

For example, the first signaling includes N pieces of configuration information corresponding to the N pieces of pre-configured resources, and N is a positive integer.

Further, the demodulation pilot information is configured in the following manner: the configuration information of each pre-configured resource in the at least one pre-configured resource includes information about one demodulation pilot.

Optionally, the demodulation pilot information is the offset information of the demodulation pilot; the offset information of the one demodulation pilot is used to determine that the demodulation pilot configuration of the pre-configured resource is relative to the first demodulation pilot configuration. A demodulation pilot configuration offset.

Manner 2: The first signaling includes configuration information of a pre-configured resource group, and the pre-configured resource group includes the at least one pre-configured resource.

For example, the first signaling includes configuration information of a pre-configured resource group.

Further, the demodulation pilot information may be configured in the following manner: the configuration information of the pre-configured resource group includes information of multiple demodulation pilots.

Optionally, the demodulation pilot information is the offset information of the demodulation pilot; the offset information of the multiple demodulation pilots is used to determine the solution of each pre-configured resource in the pre-configured resource group. The offset of the modulation pilot configuration relative to the first demodulation pilot configuration; or, the offset information of the multiple demodulation pilots is used to determine the pre-configured resource group except the first pre-configured resource The offset of the demodulation pilot configuration of each pre-configured resource relative to the second demodulation pilot configuration of the first pre-configured resource. Further, the second demodulation pilot configuration is indicated by physical layer signaling.

In an optional implementation manner, for the foregoing manner 1 and manner 2, the information of the demodulation pilot is absolute information of the demodulation pilot;

In the case that the second signaling does not contain demodulation pilot information, the demodulation pilot configuration of the pre-configured resource is determined based on the absolute information of the demodulation pilot; or,

In the case that the second signaling includes demodulation pilot information, the demodulation pilot configuration of the pre-configured resource is based on the absolute information of the demodulation pilot and/or the information in the second signaling The demodulation pilot information is determined. For example, the terminal device ignores the demodulation pilot information in the first signaling, and uses the demodulation pilot information in the second signaling to determine the demodulation pilot configuration of the pre-configured resource; or, the terminal device ignores the second signaling. The demodulation pilot information in the command uses the demodulation pilot information in the first signaling to determine the demodulation pilot configuration of the pre-configured resource; or the terminal equipment is based on the demodulation pilot in the first signaling The information (that is, absolute information) and the demodulation pilot information in the second signaling (for example, two pieces of information are superimposed and modulated) determine the demodulation pilot configuration of the pre-configured resource.

In an optional implementation manner, the first demodulation pilot configuration is indicated by physical layer signaling, and the physical layer signaling is, for example, DCI.

Further, optionally, when the physical layer signaling is the first DCI, the first demodulation pilot configuration includes default parameters. The default parameters are configured or preset by high-level signaling (that is, agreed upon by the protocol). Typically, the default parameter included in the first demodulation pilot configuration is 0.

Further, optionally, the first DCI is DCI format 0_0.

In an optional implementation manner, the first demodulation pilot configuration includes at least demodulation pilot port information.
