For example, the base station may include various forms of macro base stations, micro base stations, relay stations, access points, transmission and receiver points (TRPs), and the like. The transceiver node may be a different base station, or may be a different antenna panel of the same base station, and is not limited herein. In systems with different wireless access technologies, the names of devices with base station functionality may vary. For convenience of description, in the embodiment of the present application, the foregoing apparatus for providing a wireless communication function for a terminal is collectively referred to as a base station. It should be noted that the name of the base station and the terminal may change when the solution of the embodiment of the present application is applied to the 5G system or other systems that may occur in the future, but this does not affect the implementation of the solution in the embodiment of the present application.

In a wireless communication system, a base station and a terminal can utilize air interface resources for wireless communication. For example, in a 5G system, the air interface resource includes a frequency resource, and the frequency resource may be located in a set frequency range. The frequency range can also be referred to as a band or a frequency band. In the frequency domain, the center point of the frequency resource may be referred to as a center frequency point, and the width of the frequency domain resource may be referred to as a bandwidth (BW). Illustratively, Figure 1 shows a schematic diagram of the location of a frequency resource. As shown in FIG. 1, the frequency resource may be part or all of the resources in the frequency band, the bandwidth of the frequency resource is W, and the frequency of the center frequency point is F. The frequency of the boundary point of the frequency resource is FW/2 and F+W/2, respectively, and can also be described as the frequency of the highest frequency point in the frequency resource is F+W/2, and the frequency of the lowest frequency point in the frequency resource. For FW/2. In the wireless communication system, the frequency resource for performing downlink communication and the frequency resource for performing uplink communication may be the same or different, and the present application is not limited thereto.

When the base station and the terminal use the frequency resource for wireless communication, the base station manages the system frequency resource, and allocates the frequency resource to the terminal from the system frequency resource, so that the base station and the terminal can use the allocated frequency resource for communication. The system frequency resource may be a frequency resource that the base station can manage and allocate, and may also be a frequency resource that can be used for performing communication between the base station and the terminal.

In the frequency domain, the width of the system frequency resource may be referred to as the bandwidth of the system frequency resource, and may also be referred to as the system bandwidth or the transmission bandwidth.

In a wireless communication system, in an orthogonal frequency division multiplexing (OFDM)-based communication system, in a frequency domain, a resource that can be used for data transmission includes a plurality of resource cells, and one resource cell corresponds to one resource cell. A subcarrier, a physical resource block (PRB) has X1 resource cells, and X1 is an integer greater than or equal to 1. Illustratively, X1 is 12. The resources that can be used for data transmission may be some or all of the resources in the system resources, and the application does not limit the application. The bandwidth of resources available for data transmission may be referred to as X2 PRBs, and X2 is an integer greater than or equal to 1. For the PRBs in the resources that can be used for data transmission, the PRBs may be sequentially numbered from 0 to X2-1 based on the direction of frequency increase, and the number values of the respective PRBs are obtained. In the embodiment of the present application, the term "number value" may also be referred to as "identification" or "index". In the time domain, one PRB may include X3 symbols, and X3 is an integer greater than or equal to 1. Illustratively, X3 is 1 or 7 or 14. Taking a PRB frequency domain including 12 resource cells, the time domain includes 7 symbols as an example, as shown in FIG. 2 is a schematic structural diagram of bandwidth of resources available for data transmission, as shown in the figure, which can be used for data transmission. The bandwidth of the resource includes a total of X2 PRBs from PRB 0 to PRB X2-1.

In a 5G system, the base station allocates a frequency resource to the terminal. The base station configures the bandwidth resource for the terminal from the system frequency resource, and the base station schedules the terminal in the configured bandwidth resource. It can also be described that the base station configures the bandwidth resource for the terminal from the system frequency resource, so that the base station can allocate some or all of the configured bandwidth resources to the terminal, and perform communication between the base station and the terminal. The bandwidth resource is included in the system frequency resource, and may be a continuous or discontinuous part of the system frequency resource, or may be all resources in the system frequency resource. The bandwidth resource may also be referred to as a bandwidth part (BP), a frequency resource part, a partial frequency resource, a carrier bandwidth part or other names, which is not limited in this application. When the bandwidth resource is a contiguous resource in the system frequency resource, the bandwidth resource may also be referred to as a subband, a narrowband, or other name, which is not limited in this application. Exemplarily, as shown in FIG. 3 is a schematic structural diagram of a bandwidth resource in a system frequency resource, where the system frequency resource includes a bandwidth resource 0, that is, a subband 0, a bandwidth resource 1, that is, a subband 1 and a bandwidth resource 2, that is, a subroutine With 2 a total of 3 different bandwidth resources.

The part of the frequency resource or all the frequency resources included in the bandwidth resource A are not included in the bandwidth resource B, or the bandwidth resource. Part of the frequency resource or all frequency resources included in B is not included in the bandwidth resource A. Illustratively, in an OFDM-based communication system, the bandwidth resource A and the bandwidth resource B may be different: at least one subcarrier included in the bandwidth resource A is not included in the bandwidth resource B, or at least one subcarrier included in the bandwidth resource B Not included in bandwidth resource A.

Exemplarily, the difference between the bandwidth resource A and the bandwidth resource B may also mean that the frequency domain resources are identical, but the frame structure parameters are different, for example, the subcarrier spacing and/or the CP length may be different.

Time domain resources can be symbols. The symbol may also be referred to as a time domain symbol, which is not limited in this application. The allocated time domain symbols for data channel transmission may be dynamically changed, ie data may be transmitted at any symbol in the subframe. Exemplarily, the starting position of the time domain of the data channel may be the first symbol in the time slot or the subframe or may not be the first symbol, and the ending symbol position may be the last symbol in the time slot or the subframe. It may not be the last symbol in a time slot or a sub-frame, as shown in FIG. In a 5G system, there are multiple possibilities for the time-frequency resource location of the data channel, and the time-frequency resource location of the data channel can be indicated by the control information. In order to indicate that the data channel can be transmitted on any symbol, it is necessary to indicate the transmission condition of various data by using a plurality of bit information in the control information, thereby causing a large signaling overhead.

The downlink data channel may also be referred to as a physical downlink shared channel (PDSCH) or other name. If it is a scenario in which various data transmissions are considered, for example, slot-based data transmission, mini-slot based data transmission, and slot aggregation as a scheduling unit. (Slot aggregation or multi-slot based) data transmission, if the control information is uniformly designed, the control information signaling overhead is relatively large, because various possibilities of data channel transmission in various scenarios need to be considered. The time slot aggregation indicates that data channel transmission is performed on time domain resources of one or more slots, wherein the slot is a unit of measurement of data scheduling in the time domain. The unit of measure for data scheduling on the time domain can be called a time unit or a time schedule unit. The time scheduling unit or time unit may be a radio frame, a subframe, a slot, a mini-slot, or the like. The time scheduling unit or time unit can also be one or more symbols, etc., where the symbol is a basic unit in the time domain.

The single cell indicates that the base station and the terminal perform data transmission in only one cell, and the CoMP indicates that the base station and the terminal cooperate to perform data transmission in multiple cells. The plurality of cells may correspond to at least one base station. The CoMP has no limitation on the transmission point, and may be a coordinated multi-point transmission between the macro base station and the macro base station, the micro base station and the micro base station, and the macro base station and the micro base station. Other scenarios may include: scenarios and frequency divisions of the homogeneous network and the heterogeneous network. Frequency division duplex (FDD)/time division duplex (TDD) system, low frequency scene (sub 6G), and high frequency scene (6G or higher).

Optionally, the base station notifies the transmission status of the data channel of the terminal by using the signaling A, and then the base station notifies the transmission of the data channel of the terminal by the signaling B to one of a plurality of cases. Exemplarily, when the detection period of the control channel is less than or equal to 1 slot, the base station notifies the transmission condition of the data channel of the terminal to case 1 and case 2 through the signaling A, and the base station notifies the transmission condition of the data channel of the terminal through the signaling B. Case 1 is still case 2. Illustratively, signaling A is high layer signaling and signaling B is physical layer signaling.

Optionally, the foregoing multiple solutions for determining the transmission of the data channel may also be combined, and are not limited herein.

First, a specific example of mode 1 is given in case 1:

In the first method, the number of bits of the time domain indication information in the control information is determined according to the detection period of the control channel.

The number of bits of the time domain indication information in the control information may be determined by the detection period of the different control channels, and the number of bits of the time domain indication information in the control information determined by the detection period of the different control channels may be the same. It is different.

Optionally, the number of bits of the time domain indication information may refer to the number of bits in the control information used to indicate the time domain resource.

Optionally, the number of bits of the time domain indication information is determined according to a detection period of the control channel and a correspondence between a detection period of the control channel and a number of bits of the time domain indication information. In this embodiment of the present application, the correspondence between the detection period of the control channel and the number of bits of the time domain indication information may be set. In the embodiment of the present application, the setting may be a pre-defined or a signaling configuration, and is not limited herein. For example, the correspondence between the detection period of the control channel and the number of bits of the time domain indication information is predefined, and the number of bits of the time domain indication information is determined according to the detection period of the control channel and the correspondence. Illustratively, the base station configures, by using the signaling, a correspondence between the detection period of the control channel and the number of bits of the time domain indication information, the terminal receives the signaling, and determines the time domain according to the detection period of the control channel and the corresponding relationship. Indicates the number of bits of information. The signaling may be physical layer signaling or high layer signaling, and is not limited.

Optionally, the manner of determining the number of bits of the time domain indication information by using a correspondence between the detection period of the control channel and the number of bits of the time domain indication information may be performed by the following implementation manner. The time domain indication information may indicate a time domain length of the data channel and a time domain start location of the data channel. The number of bits of the time domain indication information is X1, and the value of the specific X1 may be predefined, that is, the correspondence is predefined.

The first embodiment assumes that when the detection period of the control channel is 7 symbols, the number of bits of the time domain indication information in the control information may be set to X1, where X1 is an integer greater than or equal to 0, and optionally, for example, X1 is 4.

As shown in FIG. 8, it is assumed that when the detection period of the control channel is 7 symbols, there are 7 cases in which the time domain length (such as the symbol length) that can be used for data channel transmission, for example, the time domain length may be 1, 2, 3, 4, 5, 6, 7 symbols. Therefore, the time domain indication information in the control information may indicate the time domain length of the data channel by 3 bits. Illustratively, since the time domain length has 7 values, the minimum is 3 Bit binary representation. For example, when the length of the field is 1 symbol, the binary can be represented as 000. When the domain length is 2 symbols, the binary can be represented as 001, and so on. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, for example, high-level signaling indicates a specific time domain length value. Specifically, it is not limited herein.

Optionally, the time domain start position of the data channel can have two meanings.

The first meaning, the time domain start position of the data channel may refer to the time domain position of the time domain start position of the data channel in the first time unit. For example, the time domain starting position of the data channel is the symbol position in the slot. For example, when the detection period of the control channel is 7 symbols, there are two possible cases for the time domain start position of the data channel, for example, the first possible time domain start position is the first symbol of the slot, The two possible starting positions are the second symbol of the slot, so the time domain indication information in the control information may be 1 bit to indicate the time domain starting position of the data channel. Exemplarily, when the value of the 1 bit is t1, the time domain start position of the data channel is the first symbol in the slot; when the value of the 1 bit is t2 or not t1, the data is represented. The time domain start position of the channel is the second symbol in the slot. Where t1 and t2 are integers. Illustratively, t1 is 0 and t2 is 1. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, such as high-level signaling indicating a specific time domain starting position and the like. Specifically, it is not limited herein.

The second meaning, the time domain start position of the data channel may refer to the positional relationship between the time domain resource location of the data channel and the time domain resource detected by the control channel (such as the PDCCH), for example, the time domain start position of the data channel may be Controls a symbol (or other time unit) following the symbol (or other time unit) detected by the channel. For example, when the detection period of the control channel is 7 symbols, there are two possible cases for the time domain start position of the data channel, for example, the time domain start position of the data channel is the first after the symbol of the control channel detection. The symbol or the second symbol after the symbol detected by the control channel, so the time domain indication information in the control information needs to indicate the time domain start position of the data channel with 1 bit. Illustratively, when the value of the 1 bit is t1, the time domain start position of the data channel is the first symbol after the symbol detected by the control channel; when the value of the 1 bit is t2 or not t1 At the time, it indicates that the time domain start position of the data channel is the second symbol after the symbol detected by the control channel. Where t1 and t2 are integers. Illustratively, t1 is 0 and t2 is 1. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, such as high-level signaling indicating a specific time domain starting position and the like. Specifically, it is not limited herein.

Optionally, the time domain start position of the data channel may also be a symbol for control channel detection, that is, the time domain resource of the data channel may include a symbol for control channel detection. As shown in FIG. 8, the dark bar represents the symbol of the control channel detection, because the interval of the symbol detected by the control channel is 7 symbols, that is, the control channel is detected once every 7 symbols, that is, the detection period of the control channel is 7 symbols, The symbol of the detection of the control channel may also be other symbols in the slot, which is not limited in this application.

Based on the above example, the time domain indication information of the data channel may be used to indicate the time domain length of the data channel and the time domain start location of the data channel. Exemplarily, when the detection period of the control channel is 7 symbols, it indicates that the time domain length of the data channel needs to be 3 bits, indicating that the time domain starting position of the data channel needs to use 1 bit, that is, the total time domain indication. The information is 4 bits, that is, X1 takes the value 4.

The time domain starting position in the embodiment of the present application may also be simply referred to as a starting position. The time domain start position may also be simply referred to as a start time unit. For example, the time unit may be at least one of a radio frame, a subframe, a time slot, a minislot, a symbol, and the like. For example, the start position of the time domain may be a start symbol, or a start time slot, and the like.

Embodiment 2: It is assumed that when the detection period of the control channel is 14 symbols, the number of bits of the time domain indication information in the corresponding control information may be X2, where X2 is an integer greater than or equal to 0, optionally, for example, X2 is 6 or 4.

Illustratively, when X2 is 6, as shown in FIG. 9, it is assumed that when the detection period of the control channel is 14 symbols, the time domain length (such as the symbol length) that can be used for data channel transmission has 8 cases, such as time domain. The length is 1, 2, 4, 6, 8, 10, 12, 14 symbols, so the time domain indication information in the control information may indicate the time domain length of the data channel by 3 bits, exemplary, due to the time domain The length has 8 values, and the minimum is represented by 3 bits. For example, when the field length is 1 symbol, the binary can be expressed as 000. When the field length is 2 symbols, the binary can be represented as 001, and so on. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, for example, high-level signaling indicates a specific time domain length value. Specifically, it is not limited herein.

Optionally, the time domain start position of the data channel can have two meanings.

The first meaning, the time domain start position of the data channel may refer to the time domain position of the time domain start position of the data channel in the first time unit. For example, the time domain starting position of the data channel is the symbol position in the slot. For example, when the detection period of the control channel is 14 symbols, there are 8 possible cases for the time domain start position of the data channel, for example, 8 kinds of time domain start positions of the data channel may be the time domain of the data channel. The start position is the first symbol of the slot or the second symbol of the slot, or the third, fourth, fifth, sixth, seventh, or eighth symbol of the slot, so the time domain indication information in the control information It is possible to use 3 bits to indicate the time domain start position of the data channel.

The starting position is the second symbol in the slot, and so on. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, such as high-level signaling indicating a specific time domain starting position and the like. Specifically, it is not limited herein.

The second meaning, the time domain start position of the data channel may refer to the positional relationship between the time domain resource of the data channel and the time domain resource detected by the control channel (such as the PDCCH), for example, the time domain start position of the data channel may be controlled.

For example, when the detection period of the control channel is 14 symbols, there are 8 possible cases for the time domain start position of the data channel, for example, the time domain start position of the data channel is the first after the symbol of the control channel detection. The symbol or the second symbol after the symbol detected by the control channel, or the third, fourth, fifth, sixth, seventh, or eighth symbol after the symbol detected by the control channel, thus the time domain indication in the control information The information needs to indicate the time domain start position of the data channel with 3 bits. Exemplarily, when the value of the three bits is 000, the time domain start position of the data channel is the first symbol after the symbol detected by the control channel; when the value of the three bits is 001, the data is represented. The time domain start position of the channel is the second symbol after the symbol detected by the control channel; and so on. The correspondence between other bit meanings and indication information is not excluded.

Optionally, the time domain start position of the data channel may also be a symbol for control channel detection, that is, the time domain resource of the data channel may include a symbol for control channel detection. The dark bar in FIG. 9 represents the symbol of the control channel detection, because the interval of the symbols detected by the control channel is 14 symbols, that is, the control channel is detected once every 14 symbols, that is, the detection period of the control channel is 14 symbols, which is optional. The symbol of the detection of the control channel may also be other symbols in the slot, which is not limited in this application.

By way of example, when X2 is 4, as shown in FIG. 9, it is assumed that when the detection period of the control channel is 14 symbols, the time domain length (such as the symbol length) that can be used for data channel transmission has four cases, for example, The time domain length is 6, 8, 12, 14 symbols, so the time domain indication information in the control information may indicate the time domain length of the data channel by 2 bits. Illustratively, since the time domain length has 4 values, The minimum is represented by a 2-bit binary. For example, when the field length is 6 symbols, the binary can be represented as 00. When the domain length is 8 symbols, the binary can be represented as 01, and so on. The correspondence between other bit meanings and indication information is not excluded. In addition, other indication methods are not excluded, for example, high-level signaling indicates a specific time domain length value. Specifically, it is not limited herein.

For example, when the detection period of the control channel is 14 symbols, there are two possible cases for the time domain start position of the data channel, for example, the time domain start position of the data channel is the first symbol after the symbol of the control channel detection. Or the second symbol after the symbol detected by the control channel, or the third symbol after the symbol detected by the control channel, or the fourth symbol after the symbol detected by the control channel, so the time domain indication information in the control information needs to be used 2 The bits indicate the start of the time domain of the data channel. Exemplarily, when the value of the 2 bits is 00, the time domain start position of the data channel is the first symbol after the symbol detected by the control channel; when the value of the 2 bits is 01, the data is indicated.

Example 1, when the detection period of the control channel is 14 symbols, the interpretation of the 3-bit time domain information is as follows: Since the detection period of the control channel is 14 symbols, the corresponding data packet is relatively large, and more symbols are needed to transmit data. At this time, the time domain resources (such as symbols) occupied by the data channel may be relatively large, for example, the position of the start symbol of the data channel may be at a relatively front position of the slot, and the position of the end symbol of the data channel may be relative to the slot. In the latter position, as shown in Table 1, the time domain information of the data channel may correspond to eight kinds of pattern and/or time domain resources and/or indication information combinations. The following is an example of pattern, time domain resources and/or combination of indication information. Similar, the specifics are not repeated here.

Take pattern as an example, that is, each identifier index corresponds to a pattern. Table 1 is only an example. The correspondence between other patterns and/or other identifiers and/or other patterns and identifiers is not excluded. Specifically, it is not limited herein.

For example, the pattern 1 is starting position 1 and the ending position is 0; pattern 2 is starting position 1 and ending position is -1; the meaning of the numbers 1, 0, -1 is the same as in the above embodiment. The same, and so on, where pattern can refer to the time-frequency resource location occupied by the data channel. For example, if the meaning of the starting position of the data channel is the location of the starting second time unit of the data channel in the first time unit, the meaning of the terminating position of the data channel is the termination of the data channel in the first time unit. The position of the second time unit, the pattern 1 is starting position 1 and the ending position is 0, which means that the data channel is transmitted from the first symbol of the slot until the last slot of the slot.

Example 2: When the detection period of the control channel is 7 symbols, the interpretation of the 3-bit correspondence is as follows. Since the detection period of the control channel is 7 symbols, the corresponding data packet is generally large, that is, a relatively small number of symbols are required to transmit data. . At this time, the time domain resource (such as a symbol) occupied by the data channel may be relatively small, for example, the position of the start symbol is in the middle of the slot, and the position of the termination symbol is in the middle of the slot. As shown in Table 2, there are eight kinds of pattern and/or time domain resources and/or combination of indication information. The following is illustrated by a pattern. The combination of time domain resources and/or indication information is similar, and details are not described herein.

Take pattern as an example, that is, each identifier index corresponds to a pattern. Table 2 is only an example. The correspondence between other patterns and/or other identifiers and/or other patterns and identifiers is not excluded. Specifically, it is not limited herein.

For example, the pattern 1 is starting position 1 and the ending position is 0; pattern 2 is starting position 1 and ending position is -1; the meaning of the numbers 1, 0, -1 is the same as in the above embodiment. The same, and so on, where pattern can refer to the time-frequency resource location occupied by the data channel. For example, if the meaning of the starting position of the data channel is the location of the starting second time unit of the data channel in the first time unit, the meaning of the terminating position of the data channel is the termination of the data channel in the first time unit. The position of the second time unit, the pattern 1 is starting position 1 and the ending position is 0, which means that the data channel is transmitted from the first symbol of the slot until the last slot of the slot.

Example 3: When the detection period of the control channel is 2 symbols, the interpretation of the 3-bit correspondence is as follows. Since the detection period of the control channel is 2 symbols, the corresponding data packet may be relatively small, that is, less symbol transmission data is required. At this time, the time domain resource (such as a symbol) occupied by the data channel may be relatively small, for example, the position of the start symbol may be in the middle of the slot, and the position of the terminating symbol may be in the middle of the slot. As shown in Table 3, there are 8 kinds of pattern and/or time domain resources and/or indication information combinations. The following is illustrated by a pattern. The time domain resources and/or the indication information combination are similar, and details are not described herein again.

Take pattern as an example, that is, each identifier index corresponds to a pattern. Table 3 is only an example. The correspondence between other patterns and/or other identifiers and/or other patterns and identifiers is not excluded. Specifically, it is not limited herein.

For example, the pattern 1 is starting position 1 and the ending position is 0; pattern 2 is starting position 1 and ending position is -1; the meaning of the numbers 1, 0, -1 is the same as in the above embodiment. The same, and so on, where pattern can refer to the time-frequency resource location occupied by the data channel. For example, if the meaning of the starting position of the data channel is the location of the starting second time unit of the data channel in the first time unit, the meaning of the terminating position of the data channel is the termination of the data channel in the first time unit. The position of the second time unit, the pattern 1 is starting position 1 and the ending position is 0, which means that the data channel is transmitted from the first symbol of the slot until the last slot of the slot.

In a possible implementation manner, the method further includes determining an indication granularity of the time domain information according to the detection period of the control channel, where the implementation manner may be combined with at least one of the foregoing embodiments, or may be a separate embodiment. The specifics are not limited herein.

Optionally, the terminal and/or the base station determine the indication granularity of the time domain information according to the detection period of the control channel.

Optionally, the indication granularity may refer to the number of the third time units included in the first time unit and/or the second time unit.

For example, when indicating the start position of the time domain, such as indicating the start symbol, it may be indicated according to the number of symbols included in the start symbol.

For example, if the information indicated by the time domain information is the start of the time domain, the time domain granularity may refer to the number of time domain units or the granularity of the start time of the time domain included in the start position of the time domain.

Optionally, the indication granularity of the time domain information may refer to the number of time units included in the information indicated by the time domain information or the granularity of the information indicated by the time domain information.

Optionally, the indication granularity of the time domain information may be that the indication method of the time domain information is indicated by one or more third time units. The third time unit may be a match, a time slot, a micro time slot, a subframe, and the like. Specifically, the case of the case 2 data channel transmission is illustrated:

In the case of the first embodiment, as shown in FIG. 10 described above, when the detection period of the control channel is two symbols, it is possible to specify that the indication granularity of the time domain information is two symbols.

Under this scheme, the indication granularity of the time domain information of one symbol can reduce the bit overhead.

For example, if the indication granularity of the time domain information is 1 symbol, it is assumed that the symbol of the starting position of the time domain (starting) can be selected among the first four symbols in the slot (for example, numbers 0, 1, 2, 3) The symbol below, assuming that the symbol of the end of the time domain (ending) can be selected from the last four symbols in the slot (such as the symbols under the numbers 13, 12, 11, 10). In this way, in order to indicate the start of the time domain, 2 bits are needed in the control information, and 2 bits are needed to indicate the termination of the time domain, that is, the number of bits of the time domain information in the control information is 4 bits. If the indication granularity of the time domain information is 2 symbols, it is assumed that the symbol of the start of the time domain is the first four symbols in the slot, because the indication granularity is 2 symbols, that is, the front 2 can be The choice (the symbol under the 0, 2 number), assuming that the symbol of the end of the time domain is still the last four symbols in the slot, because the indication granularity is 2 symbols, that is, the latter 2 options can be selected at this time. (symbols under the number 11 and 13). That is, at this time, in order to indicate that the time domain start symbol starting is 1 bit in the control information, one bit is required to indicate the time domain termination symbol ending, that is, the number of bits of the time domain information in the control information is 2 bits. Therefore, the indication granularity is 2 symbols, and the bit overhead can be reduced compared to the indication granularity of 1 symbol.

In the example 2, when the detection period of the control channel is 7 symbols, the indication granularity of the time domain information can be specified as 7 symbols.

Under this scheme, the indication granularity of the time domain information of one symbol can reduce the bit overhead.

For example, for the start of the time domain, the indication that the indication granularity of the time domain information is 1 symbol may be the same, and the length of the time domain may be indicated by a multiple of the indication granularity of the time domain information, such as a multiple of 7 symbols. For example, up to 4 times, it is represented by 2 bits. For example, bit 00 represents a time domain length of 7 symbols, and the real-time domain length is 7 symbols. For example, bit 01 represents twice the time domain length of 7 symbols, and the real-time domain length is 14 symbols. For example, bit 10 represents The time domain is three times the length of 7 symbols, and the real-time domain length is 21 symbols. For example, bit 11 represents four times the time domain length of 7, and the real-time domain length is 28 symbols.

For example, with 7 symbols as the indication granularity, the indication method of the time domain information may be only indicating the time domain position of the first 7 symbols, and subsequently indicating the number of 7 symbols.

Optionally, the indication granularity of the time domain information in the detection period of each control channel may be specified.
