This application is based on a Chinese patent application with an application number of 201811290435.9 and an application date of October 31, 2018, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated into this application by way of introduction.

Technical field

This application relates to the field of wireless communication technology, and in particular to a data transmission method, network equipment, terminal, and storage medium.

Background technique

In the new radio (NR, New Radio) system, the sounding reference signal (SRS) used for uplink and downlink beam management has four purposes, which are used for codebook (CB, CodeBook) transmission and non-codebook (NCB, Non-CodeBook) transmission, beam management (BM, Beam Management) and antenna switching (AS, Antenna Switching). In terms of time domain behavior, it is divided into periodic SRS (P-SRS), semi-persistent SRS (SP-SRS) and aperiodic SRS (AP-SRS).

The network side configures the terminal with at most one SRS resource set for codebook transmission, which contains at most two SRS resources; for high frequencies, the two SRS resources can be configured to associate different beams. The high frequency is greatly affected by factors such as occlusion, and beam switching may occur frequently. When beam switching occurs, the network side needs to reconfigure the AP-SRS resource set for the terminal through radio resource configuration (RRC, Radio Resource Control) signaling, and then trigger the terminal to send the SRS resource set through downlink control information (DCI, Downlink Control Information) This will cause a large delay (on the order of one hundred milliseconds) during the beam switching process, and it is likely that the beam switching will occur when the reconfiguration is completed. Therefore, there is currently no effective solution for how to solve the rapid switching of high-frequency beams.

detailed description

Before describing the data transmission scheme of the embodiment of the present application in detail, first, the interaction process of the beam management and the data transmission method will be briefly described. Figure 1 is a schematic diagram of the interactive process of beam management; as shown in Figure 1, it includes:

Step 101: User equipment (UE, User Equipment) reports UE capabilities, and reports the UE capabilities to a base station (gNB).

For example, if the terminal is equipped with 2 antenna panels (panels), each panel has 8 beams, then the terminal reports this capability information to the base station.

Step 102: The base station performs BM SRS configuration.

For example, the base station configures 8 SRS resources (resources), and each SRS resource corresponds to 8 beams of panel 1 in 2 panels (recorded as beam1-1 to beam1-8), and 8 beams of panel 2 (recorded as beam2-1 to beam2-8).

Step 103: The UE sends a BM SRS set (BM SRS set) to the base station, where the BM SRS set includes the above 8 SRS resources.

Step 104: The base station performs CB AP-SRS set configuration.

For example, the base station determines that beam1-1 and beam2-1 are better, and configures one CB AP-SRS set, which includes two SRS resources; among them, SRS resource 1 uses beam1-1 and SRS resource 2 uses beam2-1.

Step 105: The base station sends an SRS request to trigger the UE to send a CB AP-SRS set. For example, the base station triggers the UE to send the CB AP-SRS set through the 2-bit SRS request of DCI.

Step 106: The UE sends a CB AP-SRS set.

Step 107: The base station sends a scheduling request indication (SRI, Scheduling Request Indication).

For example, if the base station judges that the SRS resource 1 has good performance, it indicates through the SRI.

It can be seen that the network side (for example, the base station) configures a CB SRS set for the UE at most, which contains a maximum of 2 SRS resources; then the DCI 2-bit (SRS) request triggers the UE to send the CB AP-SRS set, so it cannot To achieve rapid switching of high-frequency beams, the following embodiments of the present application are proposed based on this.

The present application will be described in further detail below with reference to the drawings and specific embodiments.

The embodiments of the present application provide a data transmission method. FIG. 2 is a schematic flowchart 1 of a data transmission method according to an embodiment of the present application; as shown in FIG. 2, the method includes:

Step 201: The network device configures the terminal with configuration information of at least two aperiodic SRS (AP-SRS) resource sets; the SRS resources in the at least two aperiodic SRS resource sets are used for codebook (CB) transmission.

In this embodiment, each of the at least two aperiodic SRS resource sets includes at least one SRS resource.

The embodiment of the present application configures at least two aperiodic SRS resource sets to the terminal through the network device, to avoid that when the beam is switched, the network side needs to reconfigure the terminal for codebook transmission through RRC signaling for the aperiodic SRS The non-periodic SRS realizes the rapid switching of high-frequency beams and guarantees the system performance.

In an optional embodiment of the present application, as shown in FIG. 3, the method further includes:

Step 202: The network device configures configuration information of the mapping relationship between the indication bit of DCI and the aperiodic SRS resource set to the terminal; wherein the aperiodic SRS resource set includes aperiodic used for codebook transmission SRS resource collection.

In this embodiment, different values of the indication bits of DCI have different meanings. Taking the 2-bit indicator bit of DCI as an example, the corresponding four states include: 00-means not sending; 01-means sending SRS set; 10-means sending SRS set; 11-means sending SRS set; and the network equipment sends The terminal sends configuration information of the mapping relationship between the indication bit of DCI and the aperiodic SRS resource set.

In this embodiment, the configuration information that the network device configures the mapping relationship between the indication bit in the DCI and the aperiodic SRS resource set to the terminal includes: the network device sends the DCI to the terminal through MAC signaling Configuration information of the mapping relationship between the indicator bit of the and the aperiodic SRS resource set. Compared with RRC signaling, the use of MAC signaling can greatly reduce the delay.

In an optional embodiment of the present application, the method further includes: the network device determines the number of indication bits of the DCI through higher layer signaling.

In an optional embodiment of the present application, the number of indication bits of the DCI is 1 bit, 2 bits, or 3 bits.

In an optional embodiment of the present application, as shown in FIG. 4, the method further includes:

Step 203: The network device sends DCI to the terminal; wherein the value of the indicator bit in the DCI is determined based on the configuration information, or the value of the indicator bit in the DCI is based on a pre-agreed DCI The mapping relationship between the indicator bit and the aperiodic SRS resource set is determined.

It can be understood that the value of the indicator bit in the DCI sent by the network device to the terminal corresponds to the aperiodic SRS resource set; the value of the indicator bit in the DCI is determined based on the configuration information; or based on the pre-agreed DCI The mapping relationship between the indicator bit and the aperiodic SRS resource set is determined. For a method for determining the mapping relationship based on the pre-agreed DCI indicator bit and the aperiodic SRS resource set, it can be understood that the network device does not need to send configuration information of the mapping relationship between the DCI indicator bit and the aperiodic SRS resource set to the terminal, That is, it is not necessary to perform step 202; the mapping relationship between the indication bits of the DCI and the aperiodic SRS resource set is pre-agreed in the network device and the terminal.

The embodiments of the present application will be described below with reference to specific examples.

The network device can configure two BM SRS sets (BM SRS sets) for the terminal through RRC signaling, corresponding to the two panels of the terminal, where each BM SRS set includes 8 SRS resources; each BM SRS set corresponds to a panel The SRS resource in each BM SRS set corresponds to the beam in the panel, as shown in Table 1.

Table 1

The network device can configure 4 CB AP-SRS sets for the terminal through RRC signaling; among them, CB AP-SRS set 1 contains 2 SRS resources (SRS resource 1-1 and SRS resource 1-2, which are respectively associated with BM SRS resource 1 -1 and BM SRS resource 1-2), CB AP-SRS set 2 contains 2 SRS resources (SRS resource 2-1 and SRS resource 2-2, respectively associated with BM SRS resource 1-3 and BM SRS resource 1-4 ), CB AP-SRS set 3 contains 2 SRS resources (SRS resource 3-1 and SRS resource 3-2, respectively associated with BM SRS resource 2-1 and BM SRS resource 2-2), CB AP-SRS set 4 contains 2 A SRS resource (SRS resource 4-1 and SRS 4-2, respectively associated with BM SRS resource 2-3 and BM SRS resource 2-4), as shown in Table 2.

Table 2

Suppose that the AP-SRS set configured by the network device for the terminal has 1 NCB AP-SRS set, 1 BM AP-SRS set, and 1 AS AP-SRS set in addition to the above 4 CB AP-SRS sets. That is a total of 7 AP-SRS sets.

The network device configures the mapping relationship between the multiple states of the indication bits in the DCI and the 7 AP-SRS sets for the terminal through MAC signaling. For example, at a certain moment, the network device provides the terminal with information such as the feedback information and channel conditions of the terminal. Configure the mapping relationship shown in Figure 5a, that is, the network device can subsequently dynamically trigger the terminal to send CB AP-SRS set 1 and CB AP-SRS set 2 (with the four beams of terminal Panel 1/1 / 1-2 through DCI) / 1-3 / 1-4 association).

When the channel status information of the terminal changes, the network device configures the mapping relationship shown in Figure 5b for the UE according to the terminal's feedback information and channel conditions, that is, the network device can subsequently dynamically trigger the UE to send CB AP-SRS set through DCI1 And CB AP-SRS set 3 (associated with 2 beams of terminal Panel 1-1 / 1-2 and 2 beams of terminal Panel 2-1/2-2-2).
