In order 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 basic frame structure of NR takes time slots as the basic granularity. The symbols in each time slot are divided into three categories: downlink symbols, uplink symbols and flexible symbols. The configuration of the NR frame structure adopts a combination of semi-static configuration (that is, configuration achieved through radio resource control (Radio Resource Control, RRC) signaling) and dynamic configuration (that is, configuration achieved through DCI) for flexible configuration. In NR, both the configuration implemented through RRC signaling (belonging to the high-level configuration) and the configuration implemented through the DCI (being in the physical layer configuration) can modify the frame structure. When different configurations modify the frame structure, once a conflict occurs, it is necessary to determine the principle of mutual coverage of various configurations. In NR, the mutual coverage rules of semi-static configuration, semi-static measurement configuration, dynamic SFI and DCI are as follows:

◆The configuration of semi-statically configured uplink symbols and downlink symbols cannot be modified. The configuration of semi-statically configured flexible symbols can be modified by semi-static measurement configuration, dynamic SFI and DCI configuration.

◆The configuration of uplink symbols and downlink symbols in the semi-static measurement configuration can be changed by the dynamic SFI and DCI configuration. Once the change occurs, the behaviors related to the semi-static measurement will be terminated.

◆The data transmission of DCI configuration cannot conflict with the uplink and downlink of SFI configuration, but the flexible part of SFI configuration can be modified.

In the repeated transmission of PUSCH, a possible technical solution is that when the network is configured with dynamic SFI (hereinafter referred to as dynamic SFI), if the terminal device receives the dynamic SFI, when the dynamic SFI indicates the downlink symbol or the flexible symbol, the terminal The device cannot perform PUSCH transmission on downlink symbols or flexible symbols, so the terminal device needs to determine the symbols that can be used for repeated transmission based on the symbol direction indicated by the dynamic SFI. However, after the terminal device receives the dynamic SFI, the effective time of the dynamic SFI may be located anywhere in the repeated transmission. At this time, a clear point in time is required to determine the effective time of the dynamic SFI. To this end, the following technical solutions of the embodiments of the present application are proposed.

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

Step 201: The terminal device receives at least one piece of SFI information, and each piece of SFI information in the at least one piece of SFI information has an effective time.

In an optional implementation manner, the at least one piece of SFI information is periodically transmitted in the time domain. Based on the configuration of the SFI information by the network device, the terminal device can determine at which time domain location to receive the SFI information. Further, the network device may be a base station, such as a gNB.

For example, the terminal device receives the first SFI information in slot n-2k+m, and receives the second SFI information in slot n-k. Among them, the transmission period of SFI information is k-m slots.

In the embodiment of the present application, each SFI information in the at least one SFI information has an effective time. Further, the effective time of each SFI information is determined based on the receiving moment, the first time length, and the second time length of the SFI information; wherein, the effective time of the SFI information refers to the time from the first time domain position to the second time domain Position time, the first time domain position is obtained based on the receiving time of the SFI information plus the first time length, and the second time domain position is obtained based on the first time domain position plus the second time length .

For example: the terminal device receives the first SFI information at the first time (such as slot n-2k+m), and the effective time of the first SFI information is from "first time + T0" to "first time + T0 + T1" Time, where T0 is the first duration, and T1 is the second duration. The terminal device receives the second SFI information at the second time (such as slot nk), and the effective time of the second SFI information is the time from "the second time + T0" to "the second time + T0 + T1", where T0 is Is the first duration, and T1 is the second duration.

It should be noted that the first duration and/or second duration (that is, T0 and/or T1) of different SFI information may be the same or different. The SFI information is used to indicate the direction of the symbol that is semi-statically configured as a flexible symbol for a period of time in the future.

It should be noted that the SFI in the embodiments of the present application may also be referred to as a dynamic SFI (Dynamic SFI).

Specifically, the terminal device determines the fourth time domain position based on the starting time domain position of the time slot in which each transmission in the repeated transmission is located and the processing time required for this transmission; the fourth time domain position is based on the The starting time domain position of the transmission is obtained by subtracting the processing time required for this transmission; the terminal device determines that the fourth time domain position is located at the first effective time, and the first effective time is in the at least one SFI information The effective time of the first SFI information is determined based on the first SFI information and the actual available time domain resources corresponding to the transmission.

For example: referring to Figure 6, 1. The terminal device receives dynamic SFI1 in slot n-2k+m, and receives dynamic SFI2 in slot n-k. Among them, the period of the dynamic SFI is k-m slots, and the dynamic SFI1 and the dynamic SFI2 are used to indicate the symbol direction of the semi-static configuration as a flexible symbol for a period of time in the future. The dynamic SFI1 or SFI2 takes effect after adding T0 to the receiving time of the SFI1 or SFI2, and the effective time is T1. 2. The terminal device receives the first configuration information sent by the network device, and the first configuration information is used to configure repeated transmission, where The number of repetitions of repeated transmission is 3 times (ie, N=3), and the total time domain resources occupied by the 3 times start from symbol 2 of slot n and end to symbol 5 of slot n+1. 3.

For symbols 0 to symbol of slot n+1 3 The SFI corresponding to slot n+1 (that is, the SFI corresponding to the effective time at which the start symbol of slot n+1 is located) is used to determine the symbol direction of the flexible symbol.

In the embodiment of the present application, if the terminal device does not correctly receive the first SFI information, the terminal device determines the actual available time domain resources corresponding to all transmissions in the repeated transmission based on the semi-static configuration. Alternatively, if the terminal device does not correctly receive the first SFI information, the terminal device determines the actual available time domain resource corresponding to the transmission based on the semi-static configuration.

For example: referring to Figure 7, the terminal device may not receive dynamic SFI1 in slot n-2k+m, and/or not receive dynamic SFI2 in slot n-k. It should be noted that when the terminal device does not receive the SFI, it will only affect the symbol configuration within the effective time of the SFI.
