It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0201] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1 are illustrative, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1. The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is illustrative, each subject can not be connected or can be connected, and the connection can be in any manner, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0202] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE u02.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0203] In some embodiments, in the 5G NR system, a plurality of slot structures and indication methods are defined for the TDD frequency band to indicate the time domain resource division of the operating frequency band in a certain time window through the slot structure.

[0204] By providing multiple time slot structures and indication methods for TDD frequency bands, the TDD frequency bands can provide strong support for multiple application scenarios in the 5G system, such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine type communications (mMTC), and the like.

[0205] In some embodiments, from the perspective of transmission direction, any time slot can be composed of at least one of a downlink (DL) orthogonal frequency division multiplexing (OFDM) symbol, an uplink (UL) OFDM symbol, and a flexible OFDM symbol.

[0206] Among them, the DL OFDM symbol can only perform downlink data transmission, the UL OFDM symbol can only perform uplink data transmission, and the transmission direction on the flexible OFDM symbol can depend on the configuration or scheduling of a network device (such as a base station).

[0207] In some embodiments, the time slot definition and indication in the 5G NR system can be performed according to the following rules:

[0208] Rule 1: Only a specific direction of transmission can be performed on a determined type of OFDM symbol;

[0209] Rule 2: The time slot format is applied to a carrier, that is, only one time slot format can be used for a carrier at the same time;

[0210] Rule 3: The time slot structure only considers the symbol type in the time domain, and does not consider the frequency domain resource and function.

[0211] In some embodiments, the network device can indicate the TDD uplink-downlink configuration (UL DL configuration) currently used by the terminal in a semi-static or dynamic manner.

[0212] In some embodiments, the network device (such as a base station) can configure a semi-static TDD UL DL configuration through a system information block (SIB) and / or radio resource control (RRC) signaling.

[0213] For example, the network device can configure the cell-level uplink and downlink structure through high-layer signaling. Within the period configured by the network device, the network device can configure the terminal with the position and quantity of downlink slots, the position and quantity of downlink symbols, the position and quantity of flexible slots, the position and quantity of flexible symbols, the position and quantity of uplink slots, and the position and quantity of uplink symbols.

[0214] In some embodiments, the network device can dynamically indicate the uplink and downlink structure of one or more slots through the subframe indication (SFI) carried by the DCI of format 2_0 (i.e., DCI format 2_0).

[0215] However, the slot format configured by the above method does not consider how to adapt to different functions and does not consider the possible different directions in the frequency domain, and cannot support more types of services in the communication system.

[0216] Therefore, the embodiments of the present disclosure expect to provide a new type of frame structure to fully consider the function division of different time domain resources and different frequency domain resources, and a more efficient indication method, so as to better support more types of services in the communication system.

[0217] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiments of the present disclosure relate to a communication method, and the method comprises:

[0218] In step S2101, the network device determines the time-frequency resource structure corresponding to the working carrier of the terminal based on a predefined rule.

[0219] In some embodiments, the network device can determine the second time-frequency resource structure from a plurality of first time-frequency resource structures based on a predefined rule, and the second time-frequency resource structure is the time-frequency resource structure corresponding to the working carrier of the terminal.

[0501] For example, the transmission direction of each resource block is determined by the indication in the time domain and the indication in the frequency domain. Specifically, assuming that the indication in the time domain is DDDSU and the indication in the frequency domain is DDDSU, the transmission direction on the corresponding time-frequency resource block is determined according to the mutual operation of the time domain indication and the frequency domain indication.

[0502] In some embodiments, the base station configures the terminal with multiple sets of time-frequency resource structures, each set of time-frequency resource structures corresponding to a specific frequency domain range.

[0503] For example, assuming that the base station configures the terminal with N sets of time-frequency resource structures, the N sets of time-frequency resource structures correspond to different frequency domain resources on the terminal working carrier respectively.
