Background

Currently, there are multiple duplexing methods in a wireless communication system, and the most common of them are Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD).

In a new generation of wireless (NR) communication systems, the concept of unknown (unknown) resources is introduced. In order to make the device compatible with different duplex modes, communication modes in different duplex modes are configured on the network device and the terminal device in the prior art. In order to enable the terminal device to realize normal communication with the network device, which duplex mode is indicated to the terminal device by adding the indication information, the terminal device determines to adopt the communication mode in the corresponding duplex mode to determine the unknown time domain resource, so that data transmission between the network device and the terminal device is realized, and signaling overhead and network device configuration complexity are increased.

Disclosure of Invention

The embodiment of the application provides a method, a device and a system for indicating and determining time domain resources, which are beneficial to reducing the signaling overhead and the complexity of network equipment configuration.

In a first aspect, an embodiment of the present application provides a method for determining time domain resources, including:

and the terminal equipment receives the indication information sent by the network equipment and determines the unknown time domain resources in the time slot according to the indication information and the frequency domain resource configuration information, wherein the indication information is used for indicating the format of the time slot.

In the embodiment of the application, because the terminal device can determine the unknown time domain resource in the time slot according to the indication information and the frequency domain resource configuration information, compared with the prior art in which the duplex mode is indicated by adding the indication information, the method and the device are beneficial to reducing the signaling overhead and the complexity of network device configuration.

In one possible design, the format of the timeslot is used to indicate the number of uplink symbols and the number of downlink symbols; or, the format of the time slot is used for indicating the number and the position of the uplink symbols and the number and the position of the downlink symbols; alternatively, the format of the slot may be used to indicate the number and/or location of unknown symbols. The method is beneficial to reducing the signaling overhead of the indication information.

In one possible design, the indication information is an index number, and the index number corresponds to a format of the time slot.

In one possible design, the terminal device may determine the unknown time domain resource according to the indication information and the frequency domain resource configuration information in the following manner:

when the frequency domain resource configuration information indicates that the central frequency point of the uplink frequency domain resource is superposed with the central frequency point of the downlink frequency domain resource, the terminal equipment determines that the unknown time domain resource is a symbol in the time slot except the uplink symbol and the downlink symbol;

the uplink frequency domain resource is a frequency domain resource which is allocated to the terminal equipment by the network equipment and is used for transmitting uplink data, and the downlink frequency domain resource is a frequency domain resource which is allocated to the terminal equipment by the network equipment and is used for transmitting downlink data.

It should be noted that, the coincidence of the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource means that the central frequency point of the uplink frequency domain resource is the same as the central frequency point of the downlink frequency domain resource.

In one possible design, the terminal device determines that the unknown frequency domain resource is a frequency domain resource with a larger bandwidth in the uplink frequency domain resource and the downlink frequency domain resource.

In a possible design, the terminal device may further determine the unknown time domain resource according to the indication information and the frequency domain resource configuration information in the following manner:

when the frequency domain resource configuration information indicates that the central frequency point of the uplink frequency domain resource is not coincident with the central frequency point of the downlink frequency domain resource, the terminal equipment determines that the unknown time domain resource is a symbol obtained by merging symbols except the uplink symbol in the time slot and symbols except the downlink symbol in the time slot;

It should be noted that, the non-coincidence of the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource means that the central frequency point of the uplink frequency domain resource is different from the central frequency point of the downlink frequency domain resource.

In one possible design, the terminal device determines that the unknown frequency domain resources include uplink frequency domain resources corresponding to symbols other than the uplink symbol in the time slot and/or downlink frequency domain resources corresponding to symbols other than the downlink symbol in the time slot.

For example, when the symbols other than the uplink symbol and the downlink symbol are unknown time domain resources, the terminal device determines that the unknown frequency domain resources are frequency domain resources obtained by a union of the uplink frequency domain resources and the downlink frequency domain resources; when the uplink symbol is an unknown time domain resource, the terminal equipment determines that the unknown frequency domain resource is a downlink frequency domain resource; and when the downlink symbol is the unknown time domain resource, the terminal equipment determines that the unknown frequency domain resource is the uplink frequency domain resource.

In one possible design, the frequency domain resource configuration information indicates that a center frequency point of an uplink frequency domain resource coincides with a center frequency point of a downlink frequency domain resource, where the uplink frequency domain resource is a frequency domain resource allocated by the network device to the terminal device for transmitting uplink data, and the downlink frequency domain resource is a frequency domain resource allocated by the network device to the terminal device for transmitting downlink data.

Detailed Description

Currently, different communication modes are designed for different duplex modes, for example, for FDD, a network device configures an uplink frequency domain resource and a downlink frequency domain resource for a terminal device, and for a paired spectrum (paired spectrum), the terminal device may transmit data on the uplink frequency domain resource and the downlink frequency domain resource at the same time without indicating a time domain resource transmission state, where a specific time domain resource transmission state refers to transmitting uplink data or downlink data on the time domain resource, or not transmitting data such as for uplink and downlink switching, and in this case, the terminal device uses the time domain resource in which the uplink frequency domain resource or the downlink frequency domain resource is not used for transmitting data as an unknown time domain resource; for TDD, a network device allocates a frequency domain resource to a terminal device, and allocates an unpaired spectrum (unpaired spectrum), where the frequency domain resource may be used to transmit uplink data, and may also be used to transmit downlink data, and specifically, whether to transmit uplink data or downlink data, or not to transmit data, and the like, are related to a transmission state on a time domain resource, and specifically, in TDD, the transmission state on the time domain resource is indicated by an uplink and downlink configuration table shown in table 1, where D denotes a subframe for transmitting downlink data, U denotes a subframe for transmitting uplink data, and S denotes a special subframe.

TABLE 1

Taking the uplink and downlink configuration index in table 1 as 4 as an example, the terminal device may receive downlink data in the 0 th subframe, send uplink data in the 2 nd subframe, and perform uplink and downlink switching on the 1 st subframe on the frequency domain resource allocated by the network device, and in TDD, the terminal device determines a special subframe according to the uplink and downlink configuration index indicated by the network device, where a Guard Period (GP) in the special subframe may be equivalent to one use of an unknown time domain resource.

Therefore, in different duplexing modes, the frequency domain resources configured for the terminal device by the network device are different in mode, which results in different modes for determining the unknown time domain resources by the terminal device, and when the terminal device and the network device support both TDD and FDD, in general, in order to enable normal communication between the terminal device and the network device, the network device enables the terminal device to determine which duplexing mode is adopted for communication by sending additional indication information to the terminal device, so that the terminal device further determines the unknown time domain resources on the time domain resources in the determined corresponding duplexing mode, thereby implementing data transmission between the network device and the terminal device, but the above technical scheme increases signaling overhead and complexity of network device configuration.

In order to solve the above technical problem, an embodiment of the present application provides a method for determining time domain resources, so that a terminal device can determine unknown frequency domain resources according to indication information and frequency domain resource configuration information, where the indication information is used to indicate a format of a timeslot.

Some terms of the embodiments of the present application are explained below.

The frequency domain resource is a part of a frequency band (band) allocated to the terminal device by the network device for data transmission, and specifically, the frequency domain resource may be a Component Carrier (CC), a bandwidth part (BWP), or a carrier band (carrier band), which is not limited in this embodiment of the present invention. The BWP may be a continuous frequency domain resource or a discontinuous frequency domain resource.

The frequency domain resources include uplink frequency domain resources and downlink frequency domain resources, specifically, the uplink frequency domain resources are frequency domain resources configured by the network device to the terminal device for transmitting uplink data, and the downlink frequency domain resources are frequency domain resources configured by the network device to the terminal device for transmitting downlink data.

The frequency domain resource configuration information is used to indicate uplink frequency domain resources and downlink frequency domain resources used when data is transmitted between the terminal device and the network device, and the specific frequency domain resource configuration information may include information such as subcarrier width (SCS) parameters, bandwidth parameters, and frequency domain position parameters. For example, when the frequency-domain resource is BWP, the frequency-domain resource configuration information may also be referred to as BWP configuration information (BWP configuration information). Optionally, the frequency domain resource configuration information may indicate whether the center frequency point of the uplink frequency domain resource and the center frequency point of the downlink frequency domain resource coincide, and the terminal device may determine the unknown time domain resource by combining the information. Specific indications are discussed in detail in the following examples. It should be noted that the uplink frequency domain resource here is a frequency domain resource allocated by the network device to the terminal device for transmitting uplink data, and the downlink frequency domain resource is a frequency domain resource allocated by the network device to the terminal device for transmitting downlink data.

A slot (slot), which is a unit of a resource for transmitting data in a time domain, generally includes a plurality of symbols/chips, and each symbol/chip may have the same or different transmission directions.

A slot format, also called slot format (slot format), is used to indicate a transmission state of a terminal device on a time domain resource, for example, a slot includes 14 symbols, and the slot format specifies content carried by each symbol, for example, a first symbol is used to carry uplink data, and a second symbol is an unknown time domain resource.

The unknown time domain resource, also called an unknown time domain resource, is not used for transmitting and receiving data for the indicated terminal device, and may be used for internal processing time of the terminal device, including for uplink and downlink switching. For the base station, the unknown time domain resource may be used for uplink and downlink handover, and may also be used for communication with a terminal device or a base station other than the indicated terminal device, for example, the unknown time domain resource may be used for inter-base station measurement or other services. Specifically, the unknown time domain resource may include unknown symbols, which may also be referred to as unknown symbols.

It should be noted that, in the following description of the embodiments of the present application, an unknown time domain resource is referred to as an unknown time domain resource, an unknown symbol is referred to as an unknown symbol, an unknown frequency domain resource is referred to as an unknown frequency domain resource, and an unknown time-frequency resource is referred to as an unknown time-frequency resource. The unknown time domain resource is a resource of the unknown time frequency resource in a time domain dimension, the unknown frequency domain resource is a resource of the unknown time frequency resource in a frequency domain dimension, and the unknown frequency domain resource corresponds to the unknown time domain resource.

Fig. 1 is a schematic diagram of a possible network architecture applicable to the embodiment of the present application. The network architecture is the 5th Generation mobile communication technology (5G) network architecture. The 5G architecture may include a terminal device, a Radio Access Network (RAN), an access and mobility management function (AMF) entity, a Session Management Function (SMF) entity, a User Plane Function (UPF) entity, an independent data management (UDM) entity, an authentication service function (AUSF) entity, and a Data Network (DN). Furthermore, the 5G network architecture may include an Authentication credentialing and Processing Function (ARPF) entity, a security anchor Function (SEAF) entity, and the like, in addition to the network elements shown in fig. 1.

The main function of the RAN is to control the access of the terminal devices to the mobile communication network via radio. The RAN is part of a mobile communication system. It implements a wireless access technology. Conceptually, it resides between certain devices (e.g., a mobile phone, a computer, or any remote control machine) and provides connectivity to its core network. Included in the RAN, but not limited to, are the following devices: (G nodeB, gNB) in 5G, a home evolved nodeB (e.g., home nodeB, HNB), a baseband unit (BBU), etc.

The AMF entity is responsible for access management and mobility management of the terminal equipment. The SMF entity is responsible for session management, such as session establishment for the user. The UPF entity is a functional network element of the user plane and is mainly responsible for connecting with an external network. The DNs are responsible for networks providing services for the terminal devices, for example, some DNs provide internet access functions for the terminal devices, and other DNs provide short message functions for the terminal devices. The AUSF entity has an authentication service function for terminating the authentication function of the SEAF request. The UDM entity may store subscription information for the terminal device. The ARPF entity has an authentication certificate storage and processing function and is used for storing long-term authentication certificates of the UE, such as a permanent key K and the like. In 5G, the functions of ARPF can be incorporated into the UDM entity. The SEAF entity is used to complete the authentication process for the terminal device, and in 5G, the functions of SEAF may be incorporated into the AMF entity.

A terminal device, which is a device with wireless transceiving functionality, may be a device for providing voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. Wherein the terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). Specifically, the terminal device may be a User Equipment (UE), a mobile phone (mobile phone), a tablet (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and the like.

The network device in the embodiment of the present application may be a device in a RAN in a network architecture shown in fig. 1, such as a gNB, and the terminal device in the embodiment of the present application may be a terminal device in the network architecture shown in fig. 1.

The method for determining time domain resources according to the embodiment of the present application is specifically described below based on the communication architecture shown in fig. 1.

As shown in fig. 2, a method for determining time domain resources in an embodiment of the present application includes:

step 201, the network device sends indication information to the terminal device, wherein the indication information is used for the format of the time slot.

The indication information in this embodiment may be sent to the terminal device through physical layer signaling, for example, layer 1(layer 1, L1) signaling, or may be sent to the terminal device through layer 2(layer 2, L2) signaling, for example, Medium Access Control (MAC) signaling, or layer 3(layer 3, L3) signaling, for example, Radio Resource Control (RRC) signaling, or may be sent to the terminal device through other signaling existing in a communication process between the network device and the terminal device, which is not limited in this respect.

It should be noted that the format indicated by the indication information in this embodiment may be a format of N time slots in a certain time period, or may also be a format of a time slot used by the current terminal device for data transmission, which is not limited to this, and the specific format of the time slot indicated by the indication information may be determined by the terminal device according to a preconfigured policy, where the preconfigured policy may be sent to the terminal device by the network device, or may be configured when the terminal device leaves a factory.

Specifically, the indication information in this embodiment may be Slot Format Information (SFI), for example, the slot format information includes state information transmitted on each symbol in a slot.

In order to save signaling overhead of the indication information, optionally, the indication information in the embodiment of the present application may be an index number, where the index number corresponds to a format of the timeslot, or optionally, the indication information directly indicates the format of the timeslot.

For example, the format of the timeslot includes the number of uplink symbols and the number of downlink symbols, where the positions of the uplink symbols and the positions of the downlink symbols are pre-configured, or the determination rules of the positions of the uplink symbols and the positions of the downlink symbols are pre-configured; for another example, the format of the timeslot includes the number and position of uplink symbols and the number and position of downlink symbols; as another example, the format of the slot may include the location and/or number of unknown symbols; for example, the format of the timeslot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols, where the positions of the uplink symbols, the downlink symbols, and the unknown symbols are pre-configured, or the determination rules of the positions of the uplink symbols, the positions of the downlink symbols, and the unknown symbols are pre-configured; the uplink symbol is used for carrying uplink data, the downlink symbol is used for carrying downlink data, and the unknown may be an unknown time domain resource.

For example, when the indication information is an index number, one possible implementation manner is: the indication information indicates an index number in a corresponding relationship table of the index number and the format of the slot, where the format of the slot includes the number of uplink symbols and the number of downlink symbols, for example, the corresponding relationship table of the index number and the format of the slot may be as shown in table 2.

TABLE 2

As an example, the determination rule of the positions of the uplink symbols and the positions of the downlink symbols may be pre-configured such that the positions of the downlink symbols are consecutive by a number N1 backward from the position of the first symbol in the slot, and the positions of the uplink symbols are consecutive by a number N2 forward from the position of the last symbol in the slot, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot. In the case that the rule for determining the positions of the uplink symbols and the positions of the downlink symbols can be configured as the rule in advance, if a slot includes 14 symbols, when the indication information is the index number 1, the format of the slot is as shown in fig. 3a, the first 12 symbols are downlink symbols, and the 14 th symbol is an uplink symbol.

As another example, the determination rule of the positions of the uplink symbols and the positions of the downlink symbols may be pre-configured such that the positions of the downlink symbols are consecutive N1 backward from the first symbol position in the slot, and the positions of the uplink symbols are consecutive N2 backward from the position of the next symbol to the position where the downlink symbols end, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot. In the case that the rule for determining the positions of the uplink symbols and the positions of the downlink symbols can be configured in advance as the rule, if a slot includes 14 symbols, when the indication information is the index number 1, the format of the slot is as shown in fig. 3b, the first 12 symbols are downlink symbols, and the 13 th symbol is an uplink symbol.

In one embodiment, the rule for determining the positions of the uplink symbols and the positions of the downlink symbols may be further preconfigured to be that the positions of the downlink symbols are sequentially a number N1 backward from the first symbol position in the slot, and the start position of the uplink symbol is separated from the end position of the downlink symbol by one symbol, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot. In the case that the rule for determining the positions of the uplink symbols and the positions of the downlink symbols can be configured as the rule in advance, if a slot includes 14 symbols, when the indication information is the index number 1, the format of the slot is as shown in fig. 3a, the first 12 symbols are downlink symbols, the 14 th symbol is an uplink symbol, and the end position of the downlink symbol is separated from the start position of the uplink symbol by one symbol.

In addition, the table of the correspondence between the index number and the format of the slot may also be as shown in table 3, where the format of the slot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols.

TABLE 3

When the table of correspondence between the index number and the slot format is table 3, the configuration manner of the rule for determining the position of the uplink symbol and the position of the downlink symbol is similar to the configuration manner of the rule for determining the position of the uplink symbol and the position of the downlink symbol in table 2, and is not described herein again.

In addition, the table of the correspondence between the index number and the format of the slot may also be as shown in table 4, where the format of the slot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols.

TABLE 4

When the table of correspondence between the index number and the slot format is table 4, the configuration manner of the rule for determining the position of the uplink symbol and the position of the downlink symbol is similar to the configuration manner of the rule for determining the position of the uplink symbol and the position of the downlink symbol in table 2, and is not described herein again.

In addition, the table of correspondence between the index number and the format of the slot may also be as shown in table 5, where the format of the slot includes the position of the uplink symbol and the position of the downlink symbol.

TABLE 5

Illustratively, the 0 th to 11 th positions in the format of the slot corresponding to the index number 1 are downlink symbols, and the 13 th position is an uplink symbol.

It should be understood that, when the format of the time slot includes the number of unknown symbols, or the format of the time slot includes the position of the unknown symbols, or the format of the time slot includes the number and the position of the unknown symbols, or the format of the time slot includes the position of the uplink symbols and the position of the downlink symbols, etc., the specific implementation manner is similar to the format of the time slot including the number of the uplink symbols and the number of the downlink symbols, and will not be described herein again.

Step 202, the terminal device determines an unknown time domain resource in the time slot according to the indication information and the frequency domain resource configuration information.

The frequency domain resource configuration information may be sent to the terminal device by the network device, and in a specific implementation, the network device may send to the terminal device by a high-level signaling, such as an RRC signaling.

As an example, when the frequency domain resource configuration information indicates that the center frequency point of the uplink frequency domain resource and the center frequency point of the downlink frequency domain resource coincide, the terminal device determines the unknown time domain resource as a symbol in the time slot, except for the uplink symbol and the downlink symbol.

Optionally, the frequency domain resource configuration information may directly indicate that the center frequency point of the uplink frequency domain resource coincides with the center frequency point of the downlink frequency domain resource, or the frequency domain resource configuration information includes configuration parameters, such as SCS, bandwidth parameters (such as a bandwidth of the uplink frequency domain resource and a bandwidth of the downlink frequency domain resource), frequency domain position parameters, and the like, when the network device configures the frequency domain resource for the terminal device, the terminal device may determine that the frequency domain resource configuration information indicates that the center frequency point of the uplink frequency domain resource coincides with the center frequency point of the downlink frequency domain resource according to the parameters. Specifically, taking the frequency domain resource as BWP as an example, as shown in fig. 4, the terminal device may determine a lowest frequency position f1 of the uplink BWP according to the frequency domain position parameter of the uplink BWP, obtain an absolute bandwidth value BW1 of the uplink BWP according to the bandwidth parameter of the uplink BWP in combination with the SCS of the uplink BWP, and then determine that the center frequency of the uplink BWP is (f1+ BW 1/2); the terminal device determines the center frequency of the downlink BWP to be (f2+ BW2/2) based on the same manner, where f2 is the lowest frequency position of the downlink BWP, and BW2 is the absolute bandwidth value of the downlink BWP. If (f1+ BW1/2) — (f2+ BW2/2), the center frequency of the upstream BWP and the center frequency of the downstream BWP coincide.

It should be understood that, when the center frequency of the uplink frequency domain resource coincides with the center frequency of the downlink frequency domain resource, the frequency domain resource configured for the terminal device by the network device is an unpaired spectrum. Optionally, the terminal device may further determine that the unknown frequency domain resource is a frequency domain resource with a larger bandwidth in the uplink frequency domain resource and the downlink frequency domain resource.

Taking the indication information as index number 1 in table 2 as an example, since the number of downlink symbols corresponding to index number 1 is 12, and the number of uplink symbols is 1, for example, it is assumed that the format of the timeslot is as shown in fig. 3a, if the bandwidth of the downlink frequency domain resource is greater than the bandwidth of the uplink frequency domain resource, the unknown frequency domain resource is the downlink frequency domain resource, and further, the unknown time-frequency resource may include a time-frequency resource composed of the 13 th symbol and the downlink frequency domain resource as shown in fig. 5 a.

In addition, in this embodiment of the present application, the unknown time-frequency resource may include, as shown in a shaded area in fig. 5b, a time-frequency resource composed of the 13 th symbol and a downlink frequency-domain resource, and a time-frequency resource composed of the 14 th symbol and other frequency-domain resources, where the other frequency-domain resources are part of the downlink frequency-domain resources excluding the uplink frequency-domain resources. In this case, the unknown time domain resources are the 13 th symbol and the 14 th symbol, and the unknown frequency domain resources are the downlink frequency domain resources and other frequency domain resources.

It should be understood that, when the bandwidth of the downlink frequency domain resource is equal to the bandwidth of the uplink frequency domain resource, the unknown frequency domain resource may be the uplink frequency domain resource or the downlink frequency domain resource.

As another example, when the frequency domain resource configuration information indicates that the center frequency point of the uplink frequency domain resource and the center frequency point of the downlink frequency domain resource do not coincide, the terminal device determines that the unknown time domain resource is a symbol obtained by merging a symbol in the time slot except for the uplink symbol and a symbol in the time slot except for the downlink symbol. Taking the format of the slot shown in fig. 3a as an example, the symbols in the slot except the uplink symbol are the 1 st symbol to the 13 th symbol, and the symbols in the slot except the downlink symbol are the 13 th and 14 th symbols.

It should be noted that, in the embodiment of the present application, a manner in which the frequency domain resource configuration information indicates that the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource are not overlapped is similar to a manner in which the frequency domain resource configuration information indicates that the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource are overlapped, and details are not repeated here. It should be understood that, when the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource do not coincide, taking fig. 4 as an example, (f1+ BW1/2) ≠ (f2+ BW 2/2).

It should be understood that, when the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource do not coincide, the frequency domain resource configured by the network device for the terminal device is a paired spectrum (paired spectrum). Optionally, the terminal device determines that the unknown frequency domain resources include the uplink frequency domain resources corresponding to symbols in the time slot other than the uplink symbols and/or the downlink frequency domain resources corresponding to symbols in the time slot other than the downlink symbols.

In specific implementation, when symbols except an uplink symbol and a downlink symbol in a time slot are unknown time domain resources, the terminal equipment determines that the unknown frequency domain resources are frequency domain resources obtained by a union set of the uplink frequency domain resources and the downlink frequency domain resources; when the uplink symbol in the time slot is an unknown time domain resource, the terminal equipment determines the unknown frequency domain resource as a downlink frequency domain resource; and when the downlink symbol in the time slot is an unknown frequency domain resource, the terminal equipment determines the unknown frequency domain resource as an uplink frequency domain resource.

For example, taking the format of the corresponding time slot when the index number is 1 in table 2 as an example, if the format of the corresponding time slot when the index number is 1 is shown in fig. 3a, under the condition that the uplink frequency domain resource and the downlink frequency domain resource are required spectra, and under the condition that the 1 st symbol to the 12 th symbol are unknown time-frequency resources, the uplink frequency domain resource is unknown frequency domain resource; when the 1 st symbol to the 12 th symbol are downlink symbols, the downlink frequency domain resources are used for transmitting downlink data; the 13 th symbol is neither an uplink symbol nor a downlink symbol, so that, in the case that the 13 th symbol is an unknown time-frequency resource, the frequency-domain resource obtained by the union of the uplink frequency-domain resource and the downlink frequency-domain resource is an unknown frequency-domain resource; for the 14 th symbol as an unknown time-frequency resource, the downlink frequency-domain resource is an unknown frequency-domain resource; and in the case that the 14 th symbol is an uplink symbol, the uplink frequency domain resource is used for transmitting uplink data. In the case that the format of the time slot is as shown in fig. 3a, the unknown time-frequency resources may include time-frequency resources composed of 13 th and 14 th symbols in the time slot and downlink frequency-domain resources, and time-frequency resources composed of 1 st to 13 th symbols in the time slot and uplink frequency-domain resources, as shown in fig. 6 in the shaded area.

It should be further noted that, in the embodiment of the present application, when the correspondence between the index numbers and the formats of the time slots is shown in table 2, the network device may select any one index number from table 2 and indicate the selected index number to the terminal device regardless of whether the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are a scheduled spectrum or an unpaired spectrum, and after receiving the index number sent by the network device, the terminal device further determines the unknown time domain resource and the unknown frequency domain resource according to the index number and the frequency domain resource configuration information, where a specific manner of determining the unknown time domain resource and the unknown frequency domain resource is similar to a manner of determining the unknown time domain resource and the unknown frequency domain resource in fig. 2, and details thereof are not repeated here.

In the embodiment of the present application, when the corresponding relationship between the index numbers and the formats of the slots is shown in table 3, if a slot includes 14 symbols, since the sum of the number of the downlink symbols, the number of the uplink symbols, and the number of the unknown symbols is not greater than the total number 14 of symbols included in a slot when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device by the network device are unpaired spectrum, when the network device selects an index number from table 3 when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are unpaired spectrum, the index number in the format of a slot in which the sum of the number of the downlink symbols, the number of the uplink symbols, and the number of the unknown symbols is not greater than the total number of symbols included in a slot needs to be selected, and when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device by the network device are paired spectrum, when the network device selects an index number from table 3 when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are scheduled spectrum, the network device needs to select an index number in a format of a slot in which the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols is not greater than twice the total number of symbols included in one slot.

In the embodiment of the present application, when the correspondence between the index number and the format of the time slot is shown in table 4, when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device by the network device are unpaired peaks, the uplink symbol corresponding to the downlink frequency domain resource and the uplink symbol corresponding to the uplink frequency domain resource are the same, and the sum of the number of downlink symbols, the number of uplink symbols, and the number of uplink symbols is not greater than the total number of symbols included in one time slot, so when the network device selects the index number from table 4 and indicates the index number to the terminal device when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are unpaired peaks, it is necessary to select a symbol that satisfies that the sum of the number of uplink symbols corresponding to the downlink frequency domain resource and the number of uplink symbols corresponding to the uplink frequency domain resource is equal to the sum of symbols included in one time slot, and the sum of the number of downlink symbols, the number of uplink symbols, and the number of uplink symbols corresponding to the downlink frequency domain resource is not greater than the total number of symbols included in one time slot The index number of the format of the slot in (1). For the case that the network device configures the uplink frequency domain resource and the downlink frequency domain resource for the terminal device as a paired spectrum, any index number may be selected from the index numbers shown in table 4 to indicate to the terminal device, and the terminal device determines the unknown time-frequency resource according to the index number and the frequency domain resource configuration information, and the determination method of the unknown time-frequency resource is similar to the determination method of the unknown time-frequency resource in fig. 2, and is not described herein.

In the embodiment of the application, the unknown time domain resource in the time slot can be determined according to the indication information and the frequency domain resource configuration information, and compared with the prior art, the duplex mode used by the network equipment indicated to the terminal equipment is indicated without adding extra signaling, so that the signaling overhead is favorably reduced, and the complexity of the network equipment configuration is favorably reduced.

In addition, since the terminal device may have a situation that can only be used for transmitting uplink data or downlink data at a time point, in this case, the terminal device has uplink and downlink state switching, while the terminal device usually needs a transition time for state switching, which may be referred to as a time switching point, for switching from uplink to downlink or from downlink to uplink. Generally, one GP is usually set in the slot format, and since the GP is usually configured between the downlink symbol and the uplink symbol, as shown in fig. 7, for simplifying the implementation manner, in the embodiment of the present application, the GP may be configured within an unknown time domain resource between the downlink symbol and the uplink symbol, therefore, the unknown time domain resource in the embodiment of the present application needs to include the time domain resource between the downlink symbol and the uplink symbol, in the case of setting one GP in the slot format, optionally, when the slot format includes the number of downlink symbols and the number of uplink symbols, when the position of the downlink symbol and the position of the uplink symbol in the format of the slot indicated by the indication information are preconfigured, downlink symbols may be configured starting from the 1 st symbol position and uplink symbols may be configured starting from the last symbol position.

For example, in a case that a central frequency point of an uplink frequency domain resource and a central frequency point of a downlink frequency domain resource are overlapped, an unknown time-frequency resource shown in fig. 5a is taken as an example, where GP may be configured on a 13 th symbol; in the case that the central frequency point of the uplink frequency domain resource and the central frequency point of the downlink frequency domain resource are not coincident, take the unknown time-frequency resource shown in fig. 6 as an example, wherein GP is also generally configured on the 13 th symbol.

In addition, two GPs may be further set in the format of the time slot, at this time, in order to configure the two GPs in the unknown time domain resource between the downlink symbol and the uplink symbol, optionally, when the indication information indicates the format of the time slot, the time slot is divided into two parts, i.e., the first part and the second part, for indication, taking the indication information as an index number as an example, and assuming that the number of symbols included in the first part is the same as the number of symbols included in the second part, the corresponding relationship between the index number and the format of the time slot may be as shown in table 6.

TABLE 6

Taking an example that one slot includes 14 symbols, where the first portion includes 7 symbols, and the second portion includes 7 symbols, if the positions of the first portion and the second portion of the downlink symbols and the positions of the uplink symbols are preconfigured, the downlink symbols are configured backward from the 1 st symbol position of the portion, and the uplink symbols are configured forward from the last symbol of the portion, then the index number is 1, the corresponding slot format may be as shown in fig. 8a, and therefore, it can be seen from the slot format shown in fig. 8a that the positions of the first portion of the unknown symbols are located between the downlink symbols and the uplink symbols, and the positions of the second portion of the unknown symbols are located between the downlink symbols and the uplink symbols, so that the network device does not need to send an additional signaling indication GP to the terminal device in the above manner.

For example, when two GPs are set in the slot format, the correspondence between the index number and the slot format may also be as shown in table 7.

TABLE 7

For example, assuming that a slot includes 14 symbols, the corresponding slot format with index 1 may be as shown in fig. 8b, where an unknown symbol is divided into two parts, and it can be seen from the slot format shown in fig. 8b that the position of the unknown symbol in the first part is located between the downlink symbol and the uplink symbol, and the position of the unknown symbol in the second part is located between the downlink symbol and the uplink symbol.

It should be noted that three or more GPs may also be set in the slot format in the above manner, which is not described herein again.
