Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a time domain resource configuration method, a terminal, a network device and a storage medium. Background Art

[0002] In the long-delay network of the prior art, such as the time division duplex (TDD) network of the air-to-ground communication system (ATG), it is necessary to configure sufficient guard period (GP) to prevent uplink and downlink interference. According to the relevant GP calculation formula, when the cell diameter reaches 300km, the GP needs to be more than 2ms. Usually, the GP length of the ground cell is much less than 0.5ms. Too large GP will cause a great loss in system throughput.

[0003] A solution to the problem of system throughput being affected by an excessively large GP is: Assume that the GP is 2ms, the round-trip time (RTT) between the terminal (UE) and the network is 2ms, and one time slot is 0.5ms; the configuration of the TDD pattern without terminal assistance is as follows: Figure 1 As shown, Figure 1 Each small square in the figure represents a time slot, D represents a downlink time slot, G represents a GP time slot, and U represents an uplink time slot. The frame structure of the TDD pattern configuration includes 10 time slots, which are 4 downlink time slots (D), 4 GP (G) and 2 uplink time slots (U). In this scheme, the terminal reports the propagation delay RTT = 2ms, and the auxiliary base station performs TDD pattern configuration. The terminal-assisted TDD pattern) configuration is as follows Figure 2 As shown, the base station (gNB) will Figure 1 The last two GP time slots of the four GP time slots are set as downlink time slots, thereby reducing the number of GP time slots and improving system throughput.

[0004] Among them, the scheme for the base station to obtain the propagation delay between the base station and the terminal is:

[0005] 1. When the terminal does not perform uplink delay pre-compensation, the propagation delay can be obtained based on the TA;

[0006] 2. When the terminal performs uplink delay pre-compensation, the propagation delay can be obtained based on the first TA (TA sent by the network) + the second TA (TA reported by the terminal), or based on the total TA reported by the UE.

[0007] Currently, the trigger conditions for UE to report TA are:

[0008] 1. TA reporting during the random access channel (RACH) access process is enabled / disabled by system information (SI); the RACH access process for reconstruction controlled by the target cell's SI and the handover process controlled by the handover command (HO command) are considered separately.

[0009] 2. When the terminal is in a connected state, reporting is performed based on event triggering, and the triggering event is: whether the change between the current TA and the TA reported last time by the terminal exceeds the threshold.

[0010] The reporting method is as follows: if the UE-specific TA pre-compensation is reported, it is reported through a new Medium Access Control Control Element (MACCE).

[0011] The specific content of TA reporting (TAR) is: reporting Full TA, occupying 2 bytes of MAC CE.

[0012] In order to obtain a higher system throughput, the base station needs to configure different TDD patterns according to the different propagation delays between the terminal and the base station. A possible TDD pattern is as follows: Figure 3 However, the current TDD pattern configuration scheme does not support configuring a flexible symbol first and then configuring the flexible symbol as a downlink symbol in a time slot (such as Figure 3 Therefore, it is difficult to improve the system throughput.

In addition, features described with reference to certain examples may be combined in other examples.

[0141] As described in the background technology, the TDD pattern configuration scheme in the related art does not support configuring flexible symbols first and then configuring downlink symbols within a time slot, which is not conducive to improving the system throughput.

[0142] In addition, if the TDD pattern of the terminal is not updated in time due to the propagation delay between the terminal and the base station, uplink and downlink conflicts may occur, such as Figure 4 If the existing TA reporting mechanism is adopted, each report needs to consume 16 bits, resulting in a large uplink overhead.

[0143] Furthermore, if different TDD patterns are configured for different terminals, interference may occur between the terminals, such as Figure 5 As shown, the uplink of terminal 2 will interfere with the downlink of terminal 1.

[0144] To solve at least one of the above problems, an embodiment of the present application provides a time domain resource configuration method, which can improve the flexibility of time domain resource configuration and thereby improve system throughput.

[0145] Please refer to Figure 6 , a time domain resource configuration method provided in an embodiment of the present application, when applied to a network device side, the network device may specifically be a ground base station, a transceiver point (TRP), a satellite or other device, and the method includes:

[0146] Step 61: Send a first message, where the first message includes:

[0147] At least one set of time domain resource configurations and a propagation delay offset range indicator value corresponding to each set of time domain resource configurations, wherein the time domain resource configuration is a TDD flexible time slot configuration or a first scheduling restriction configuration, and each propagation delay offset range indicator value corresponds to a signal propagation delay offset range;

[0148] or,

[0149] The second scheduling restriction configuration.

[0150] Here, the signal propagation delay offset range refers to the range to which the signal propagation delay between the terminal and the network device belongs. The signal propagation delay can be represented by any of the following methods: time advance (TA), propagation delay from the network device (such as a base station / TRP) to the terminal, round-trip delay (RTT) from the network device (such as a base station / TRP) to the terminal, etc. In the embodiment of the present application, the signal propagation delay can be divided into several continuous and non-overlapping signal propagation delay offset ranges, each of which corresponds to a propagation delay offset range indication value, so that the signal propagation delay offset range can be indicated by the propagation delay offset range indication value.

[0151] The first scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the time slots and / or symbols used for uplink and downlink transmission to be restricted. The second scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the number of symbols used for downlink transmission before and after the terminal uplink symbol to be restricted. The TDD common uplink and downlink resource configuration can be a TDD pattern configured by TDD-UL-DL-ConfigCommon.

[0152] The first message may be an RRC message or other signaling messages.

[0153] Through the above steps, in the embodiment of the present application, the network device can send at least one set of TDD flexible time slot configurations and the propagation delay offset range indication value corresponding to each set of TDD flexible time slot configurations to the terminal through a first message, or send at least one set of first scheduling restriction configurations and the propagation delay offset range indication value corresponding to each set of first scheduling restriction configurations to the terminal, or send a second scheduling restriction configuration to the terminal, so that the terminal can select the corresponding time domain resource configuration according to its own propagation delay, thereby improving the flexibility of the time domain resource configuration and facilitating improving the system throughput.

[0154] In order to facilitate the terminal to determine the signal propagation delay offset range to which its own signal propagation delay belongs, the first message may also include: a maximum propagation delay value and a propagation delay offset value, wherein: the maximum propagation delay value is the maximum value of the signal transmission delay between the terminal and the network device supported by the time domain resource configuration or the second scheduling restriction configuration, and the propagation delay offset value is the difference between the upper and lower limits of the signal propagation delay offset range supported by each set of time domain resource configuration or the second scheduling restriction configuration. In this way, the terminal can determine the upper and lower limits of the signal propagation delay offset range corresponding to the propagation delay offset range indicator value according to the maximum propagation delay value, the propagation delay offset value and the propagation delay offset range indicator value, that is, determine the signal propagation delay offset range corresponding to each propagation delay offset range indicator value.

[0155] The three situations of resource configuration included in the first message are described in detail below.

[0156] The first case: the first message includes: at least one set of TDD flexible time slot configurations and a propagation delay offset range indication value corresponding to each set of TDD flexible time slot configurations.

[0157] In the embodiment of the present application, the at least one set of time domain resource configuration included in the first message is at least one set of TDD flexible time slot configuration. Specifically, the TDD flexible time slot configuration includes:

[0158] (1) a time slot index of the TDD flexible time slot;

[0159] (2) a symbol index of the first downlink symbol in the TDD flexible time slot;

[0160] (3) A first number of consecutive downlink symbols starting from the first downlink symbol in the TDD flexible time slot, or a second number of consecutive downlink symbols starting from the next symbol after the first downlink symbol in the TDD flexible time slot.

[0161] Here, downlink symbols refer to symbols used for downlink transmission, and similarly, uplink symbols refer to symbols used for uplink transmission. In the embodiment of the present application, downlink symbols for downlink transmission are configured in TDD flexible time slots, and different TDD flexible time slot configurations may configure different downlink symbols.

[0162] The second case: the first message includes: at least one set of first scheduling restriction configurations and a propagation delay offset range indication value corresponding to each set of first scheduling restriction configurations.

[0163] In the embodiment of the present application, the at least one set of time domain resource configuration included in the first message is at least one set of first scheduling restriction configuration. The first scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures and restricts the time slots and / or symbols used for uplink and downlink transmission. Specifically, the first scheduling restriction configuration includes:

[0164] (1) Limit the time domain starting position of the time domain resources used for uplink and downlink transmission.

[0165] (2) Limiting the time domain end position or time domain length of the time domain resources used for uplink and downlink transmission.

[0166] For example, the time domain starting position may include: limiting the time slot index of the starting time slot for downlink transmission. The time domain ending position may include: limiting the time slot index of the ending time slot for downlink transmission. The time domain length may include: limiting the number of consecutive time slots for downlink transmission, and / or limiting the number of consecutive symbols for downlink transmission. Optionally, the time domain starting position may also include: limiting the symbol index corresponding to the starting symbol for downlink transmission; the time domain ending position also includes: limiting the symbol index corresponding to the ending symbol for downlink transmission.

[0167] For another example, the time domain starting position may include: limiting the time slot index of the starting time slot used for uplink transmission. The time domain ending position may include: limiting the time slot index of the ending time slot used for uplink transmission. The time domain length may include: limiting the number of consecutive time slots used for uplink transmission, and / or limiting the number of consecutive symbols used for uplink transmission. Optionally, the time domain starting position may also include: limiting the symbol index corresponding to the starting symbol used for uplink transmission; the time domain ending position also includes: limiting the symbol index corresponding to the ending symbol used for uplink transmission.

[0168] Through the above configuration, the time domain resources for uplink and downlink transmission can be flexibly configured. In addition, the time domain resources for uplink and downlink transmission configured by different first scheduling restriction configurations can be different.

[0169] For the first and second situations above, the network device sends the first message. Assuming that a certain terminal (for ease of description, referred to as the first terminal) receives the first message, it can determine the first propagation delay offset range indicator value corresponding to the first signal propagation delay offset range according to the first signal propagation delay offset range to which its own first signal propagation delay belongs, and send a second message to the network device, the second message including the first propagation delay offset range indicator value. Here, the first signal propagation delay belongs to the signal propagation delay offset range corresponding to the first propagation delay offset range indicator value. The network device receives the second message sent by the first terminal, thereby obtaining the first propagation delay offset range indicator value.

[0170] In this way, the network device can use the first time domain resource configuration corresponding to the first propagation delay offset range indicator value to schedule data for the first terminal, and the first terminal uses the first time domain resource configuration to send and receive data. For example, in the first case, the network device uses the TDD flexible time slot configuration corresponding to the first propagation delay offset range indicator value to schedule data for the first terminal, or uses the first scheduling restriction configuration corresponding to the first propagation delay offset range indicator value to schedule data for the first terminal.

[0171] In addition, in an embodiment of the present application, the network device may use the first time domain resource configuration to schedule data for the first terminal in the next scheduling period after receiving the second message. Alternatively, after receiving the second message, the network device sends a first HARQ feedback message to the first terminal, and the first HARQ feedback message is used to indicate that the second message has been received; in the next scheduling period after sending the first HARQ feedback message, the network device uses the first time domain resource configuration to schedule data for the first terminal, so that both the sender and the receiver have obtained the information of the first time domain resource configuration. Usually, the network device and the terminal side can pre-agree on the timing of using the first time domain resource configuration.

[0172] For the first and second situations above, considering that different terminals use different time domain resource configurations (such as different TDD flexible time slot configurations or different first scheduling restriction configurations), interference may occur between terminals. To solve the above interference problem, in an embodiment of the present application, the network device can determine whether there is interference between the time domain resource configurations of different terminals based on the propagation delay offset range indication values ​​fed back by different terminals, and perform relevant processing to avoid interference when there is interference.

[0173] For example, assume that after sending a first message, the network device receives a second message sent by a first terminal and a third message sent by a second terminal, wherein the second message includes: a first propagation delay offset range indication value corresponding to the first signal propagation delay, and the first signal propagation delay belongs to the signal propagation delay offset range corresponding to the first propagation delay offset range indication value; and the third message includes: a second propagation delay offset range indication value corresponding to the second signal propagation delay, and the second signal propagation delay belongs to the signal propagation delay offset range corresponding to the second propagation delay offset range indication value.

[0174] At this time, the network device determines the first time domain resource configuration corresponding to the first propagation delay offset range indicator value and the second time domain resource configuration corresponding to the second propagation delay offset range indicator value. Then, the network device can determine whether there is interference between the first time domain resource configuration and the second time domain resource configuration.

[0175] For example, in the case where the second time domain resource configuration generates uplink interference to the flexible time slot of the first time domain resource configuration, the network device may configure a downlink reference signal for interference measurement for the non-flexible time slot and the flexible time slot of the first time domain resource configuration, and send the downlink reference signal in the non-flexible time slot and the flexible time slot of the first time domain resource configuration. In this way, the first terminal can perform interference measurement according to the above configuration and feed back the measurement result to the network device.

[0176] If the network device receives a fourth message sent by the first terminal, and the fourth message is used to indicate that the difference in interference intensity between the flexible time slot and the non-flexible time slot exceeds a preset threshold, the network device can use the third time domain resource configuration to schedule data for the first terminal, wherein the third time domain resource configuration cancels the downlink transmission resources configured by the first time domain resource configuration in the TDD flexible time slot on the basis of the TDD common uplink and downlink resource configuration.

[0177] In addition, the network device may use the third time domain resource configuration to schedule data for the first terminal in the next scheduling period after receiving the fourth message, or the network device may send a second HARQ feedback message to the first terminal after receiving the fourth message, and the second HARQ feedback message is used to indicate that the fourth message has been received; in the next scheduling period after sending the second HARQ feedback message, the third time domain resource configuration is used to schedule data for the first terminal. Usually, the network device and the terminal side may pre-agree on the timing of using the third time domain resource configuration.

[0178] Furthermore, the network device can also use a timer to decide when to stop using the third time domain resource configuration to schedule data for the first terminal. Specifically, the network device starts the first timer in the next scheduling period after receiving the fourth message, or in the next scheduling period after sending the second HARQ feedback message, and after the first timer times out, receives the fifth message sent by the first terminal, the fifth message including: a third propagation delay offset range indicator value corresponding to the third signal propagation delay, the third signal propagation delay is the signal propagation delay measured by the first terminal after the first timer times out, and belongs to the signal propagation delay offset range corresponding to the third propagation delay offset range indicator value; then, the network device can use the fourth time domain resource configuration corresponding to the third propagation delay offset range indicator value to schedule data for the first terminal. Usually, the network device and the terminal side can pre-agree on the timing of using the fourth time domain resource configuration.

[0179] Through the above methods, the embodiments of the present application can reduce interference between terminals, improve signal transmission quality, and increase system throughput.

[0180] The third situation: the first message includes: a second scheduling restriction configuration.

[0181] In an embodiment of the present application, at least one set of time domain resource configuration included in the first message is a second scheduling restriction. The second scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the number of symbols before and after the terminal uplink symbol to be restricted for downlink transmission. For example, the first n symbols adjacent to a certain uplink symbol are configured to be prohibited from being used for downlink transmission, and / or, the last m symbols adjacent to a certain uplink symbol are configured to be prohibited from being used for downlink transmission, where n and m are integers greater than or equal to 0, and n and m can be equal or unequal.

[0182] At this time, the first terminal can determine the fourth propagation delay offset range indicator value corresponding to the fourth signal propagation delay offset range according to the fourth signal propagation delay to which its own fourth signal propagation delay belongs, and then send a sixth message to the network device. The network device receives the sixth message sent by the first terminal, and the sixth message includes: the fourth propagation delay offset range indicator value corresponding to the fourth signal propagation delay, and the fourth signal propagation delay belongs to the signal propagation delay offset range corresponding to the fourth propagation delay offset range indicator value. Then, the network device determines the fifth time domain resource configuration according to the fourth signal propagation delay offset range and the second scheduling restriction configuration. For example, the network device determines the time domain position range where the uplink resource is located after the terminal performs TA compensation according to the fourth signal propagation delay offset range, and determines the fifth time domain resource configuration according to the second scheduling restriction configuration, that is, the number of symbols x before and after the time domain position range that are limited for downlink transmission, that is, the x symbols before and after the time domain position range are not scheduled for uplink and downlink time domain resources. Then, the fifth time domain resource configuration is used to schedule data for the first terminal.

[0183] In addition, in the case where the sixth message is the fourth signal propagation delay, in an embodiment of the present application, the network device may use the fifth time domain resource configuration to schedule data for the first terminal in the next scheduling period after receiving the sixth message; or, after receiving the sixth message, send a third HARQ feedback message to the first terminal, and the third HARQ feedback message is used to indicate that the sixth message has been received; in the next scheduling period after sending the third HARQ feedback message, use the fifth time domain resource configuration to schedule data for the first terminal.

[0184] In addition, the sixth message may also be: the fourth signal propagation delay. Then, the network device determines the sixth time domain resource configuration according to the fourth signal propagation delay and the second scheduling restriction configuration. For example, the network determines the time domain position range of the uplink resource after the terminal performs TA compensation at this time according to the fourth signal propagation delay, and determines the sixth time domain resource configuration according to the second scheduling restriction configuration, that is, the number of symbols x before and after the time domain position for downlink transmission, that is, the x symbols before and after the time domain position are not scheduled for uplink and downlink time domain resources. Then, the sixth time domain resource configuration is used to schedule data for the first terminal.

[0185] In addition, in an embodiment of the present application, the network device may use the sixth time domain resource configuration to schedule data for the first terminal in the next scheduling period after receiving the sixth message; or, after receiving the sixth message, send a third HARQ feedback message to the first terminal, and the third HARQ feedback message is used to indicate that the sixth message has been received; and use the sixth time domain resource configuration to schedule data for the first terminal in the next scheduling period after sending the third HARQ feedback message.

[0186] It can be seen from the above embodiments that the above method of the embodiment of the present application utilizes the pre-configured TDD pattern configuration scheme (such as TDD flexible time slot configuration, first scheduling restriction configuration, and second scheduling restriction configuration). On the one hand, it can improve the flexibility of time domain resource configuration and thus improve the system throughput. On the other hand, the terminal only needs to report the propagation delay offset range indication value, which can save the signaling overhead of the terminal reporting the propagation delay and align the TDD pattern effective time of the terminal and the base station.

[0187] The solution of the above-mentioned embodiment of the present application can support configuring flexible symbols first and then configuring the flexible symbols as downlink symbols within a time slot, so that through the TDD configuration of this solution, a suitable TDD pattern can be selected based on the propagation delay of the terminal, which is conducive to improving system throughput.

[0188] In addition, the embodiment of the present application also avoids the uplink and downlink interference problem caused by the untimely update of the TDD pattern as the terminal propagation delay report is not timely through the terminal reporting the indication value corresponding to the propagation delay range, and the base station configures the TDD pattern configuration within the range / a range larger than the range.

[0189] In addition, the embodiment of the present application also configures reference signal configuration, interference threshold indication and TDD flexible slot configuration invalid time window, so that when interference occurs, the throughput loss caused by interference can be avoided or reduced through system resource scheduling.

[0190] Please refer to Figure 7 A time domain resource configuration method provided in an embodiment of the present application, when applied to a terminal side (assuming it is a first terminal), includes:

[0191] Step 71: Receive a first message sent by a network device, where the first message includes:

[0192] At least one set of time domain resource configurations and a propagation delay offset range indicator value corresponding to each set of time domain resource configurations, wherein the time domain resource configuration is a TDD flexible time slot configuration or a first scheduling restriction configuration, and each propagation delay offset range indicator value corresponds to a signal propagation delay offset range;

[0193] or,

[0194] The second scheduling restriction configuration.

[0195] Here, the network device can send the above-mentioned first message to the first terminal through RRC and other messages. The first scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the time slots and / or symbols used for uplink and downlink transmission to be restricted. The second scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the number of symbols used for downlink transmission before and after the terminal uplink symbol to be restricted. The TDD common uplink and downlink resource configuration can be a TDD pattern configured by TDD-UL-DL-ConfigCommon.

[0196] Through the above steps, in the embodiment of the present application, the terminal can obtain at least one set of TDD flexible time slot configurations and the propagation delay offset range indication value corresponding to each set of TDD flexible time slot configurations through the first message, or obtain at least one set of first scheduling restriction configurations and the propagation delay offset range indication value corresponding to each set of first scheduling restriction configurations, or obtain the second scheduling restriction configuration, so that the terminal can select the corresponding time domain resource configuration according to its own propagation delay, thereby improving the flexibility of the time domain resource configuration and facilitating improving the system throughput.

[0197] In order to facilitate the terminal to determine the signal propagation delay offset range to which its own signal propagation delay belongs, the first message may also include: a maximum propagation delay value and a propagation delay offset value, wherein: the maximum propagation delay value is the maximum value of the signal transmission delay between the terminal and the network device supported by the time domain resource configuration or the second scheduling restriction configuration, and the propagation delay offset value is the difference between the upper and lower limits of the signal propagation delay offset range supported by each set of time domain resource configuration or the second scheduling restriction configuration.

[0198] The upper and lower limits of the signal propagation delay offset range may be determined according to the maximum propagation delay value, the propagation delay offset value, and the propagation delay offset range indication value. In this way, the terminal may determine the upper and lower limits of the signal propagation delay offset range corresponding to the propagation delay offset range indication value according to the maximum propagation delay value, the propagation delay offset value, and the propagation delay offset range indication value, that is, determine the signal propagation delay offset range corresponding to each propagation delay offset range indication value.

[0199] For example, a calculation method for determining the upper and lower limits of the signal propagation delay offset range corresponding to a certain propagation delay offset range indicator value is as follows:

[0200] The upper limit of the signal propagation delay offset range = the maximum propagation delay - R * propagation delay offset value The lower limit of the signal propagation delay offset range = the maximum propagation delay - (R + 1) * propagation delay offset value

[0201] The subsequent terminal can determine the propagation delay offset range indication value corresponding to the signal propagation delay offset range according to the signal propagation delay offset range to which its own signal propagation delay belongs, and send the indication value through the network device to indicate the signal propagation delay offset range to which the terminal's own signal propagation delay belongs, thereby reducing the signaling overhead of the terminal reporting the propagation delay. In addition, the terminal and the network can use the same TDD pattern for data transmission and reception / data scheduling based on the same indication value, thereby aligning the TDD pattern effectiveness time of the terminal and the base station.

[0202] The three situations of resource configuration included in the first message are described in detail below.

[0203] The first case: the first message includes: at least one set of TDD flexible time slot configurations and a propagation delay offset range indication value corresponding to each set of TDD flexible time slot configurations.

[0204] In the embodiment of the present application, the at least one set of time domain resource configuration included in the first message sent by the network device is at least one set of TDD flexible time slot configuration. Specifically, the TDD flexible time slot configuration includes:

[0205] (1) a time slot index of the TDD flexible time slot;

[0206] (2) a symbol index of the first downlink symbol in the TDD flexible time slot;

[0207] (3) A first number of consecutive downlink symbols starting from the first downlink symbol in the TDD flexible time slot, or a second number of consecutive downlink symbols starting from the next symbol after the first downlink symbol in the TDD flexible time slot.

[0208] The second case: the first message includes: at least one set of first scheduling restriction configurations and a propagation delay offset range indication value corresponding to each set of first scheduling restriction configurations.

[0209] In the embodiment of the present application, at least one set of time domain resource configuration included in the first message sent by the network device is at least one set of first scheduling restriction configuration. The first scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures and restricts the time slots and / or symbols used for uplink and downlink transmission. Specifically, the first scheduling restriction configuration includes:

[0210] (1) Limit the time domain starting position of the time domain resources used for uplink and downlink transmission.

[0211] (2) Limiting the time domain end position or time domain length of the time domain resources used for uplink and downlink transmission.

[0212] For example, the time domain starting position may include: limiting the time slot index of the starting time slot for downlink transmission. The time domain ending position may include: limiting the time slot index of the ending time slot for downlink transmission. The time domain length may include: limiting the number of consecutive time slots for downlink transmission, and / or limiting the number of consecutive symbols for downlink transmission. Optionally, the time domain starting position may also include: limiting the symbol index corresponding to the starting symbol for downlink transmission; the time domain ending position also includes: limiting the symbol index corresponding to the ending symbol for downlink transmission.

[0213] For another example, the time domain starting position may include: limiting the time slot index of the starting time slot used for uplink transmission. The time domain ending position may include: limiting the time slot index of the ending time slot used for uplink transmission. The time domain length may include: limiting the number of consecutive time slots used for uplink transmission, and / or limiting the number of consecutive symbols used for uplink transmission. Optionally, the time domain starting position may also include: limiting the symbol index corresponding to the starting symbol used for uplink transmission; the time domain ending position also includes: limiting the symbol index corresponding to the ending symbol used for uplink transmission.

[0214] Through the above configuration, the time domain resources for uplink and downlink transmission can be flexibly configured. In addition, the time domain resources for uplink and downlink transmission configured by different first scheduling restriction configurations can be different.

[0215] For the first and second situations mentioned above, after receiving the first message sent by the network device, the first terminal can determine the first propagation delay offset range indicator value corresponding to the first signal propagation delay offset range according to the first signal propagation delay offset range to which its own first signal propagation delay belongs, and send a second message to the network device, wherein the second message includes the first propagation delay offset range indicator value. Here, the first signal propagation delay belongs to the signal propagation delay offset range corresponding to the first propagation delay offset range indicator value. In this way, the network device obtains the first propagation delay offset range indicator value when receiving the second message sent by the first terminal, and then uses the first time domain resource configuration corresponding to the first propagation delay offset range indicator value to schedule data for the first terminal, and the first terminal can use the first time domain resource configuration corresponding to the first propagation delay offset range indicator value to send and receive data.

[0216] In an embodiment of the present application, the first terminal may use the first time domain resource configuration to send and receive data in the next scheduling period after sending the second message; or, after sending the second message, the first terminal receives a first HARQ feedback message sent by the network device, and the first HARQ feedback message is used to indicate that the second message has been received; in the next scheduling period after receiving the first HARQ feedback message, the first time domain resource configuration is used to send and receive data.

[0217] In an embodiment of the present application, the network device may also perform relevant processing for interference avoidance on the first terminal. Specifically, the first terminal sends a second message to the network device, and the second message includes: a first propagation delay offset range indicator value corresponding to the first signal propagation delay, and the first signal propagation delay belongs to the signal propagation delay offset range corresponding to the first propagation delay offset range indicator value. If the first terminal subsequently receives configuration information sent by the network, the configuration information is used to configure a non-flexible time slot for the first time domain resource configuration and a downlink reference signal for the flexible time slot configuration for interference measurement, and the first time domain resource configuration is the time domain resource configuration corresponding to the first propagation delay offset range indicator value. Then, the first terminal performs interference measurement on the non-flexible time slot and the flexible time slot configuration of the first time domain resource configuration according to the configuration information.

[0218] If the difference in interference intensity between the flexible time slot and the non-flexible time slot exceeds a preset threshold, the first terminal may send a fourth message to the network device and use the third time domain resource configuration for data transmission and reception. Here, the fourth message is used to indicate that the difference in interference intensity between the flexible time slot and the non-flexible time slot exceeds a preset threshold. The third time domain resource configuration cancels the downlink transmission resources configured in the TDD flexible time slot by the first time domain resource configuration on the basis of the TDD common uplink and downlink resource configuration.

[0219] Specifically, the first terminal may use the third time domain resource configuration to send and receive data in the next scheduling period after sending the fourth message, or, after sending the fourth message, receive a second HARQ feedback message sent by the network device, wherein the second HARQ feedback message is used to indicate that the fourth message has been received; and use the third time domain resource configuration to send and receive data in the next scheduling period after receiving the second HARQ feedback message.

[0220] Further, the first terminal starts a second timer in the next scheduling period after sending the fourth message, or in the next scheduling period after receiving the second HARQ feedback message, and sends a fifth message to the network device after the second timer times out, wherein the fifth message includes: a third propagation delay offset range indicator value corresponding to a third signal propagation delay, wherein the third signal propagation delay is the signal propagation delay measured by the first terminal after the second timer times out, and belongs to the signal propagation delay offset range corresponding to the third propagation delay offset range indicator value; and uses the fourth time domain resource configuration corresponding to the third propagation delay offset range indicator value for data transmission and reception. The second timer may be the same as or similar to the timeout period of the first timer on the network device side.

[0221] Through the above methods, the embodiments of the present application can reduce interference between terminals, improve signal transmission quality, and thus increase system throughput.

[0222] The third situation: the first message includes: a second scheduling restriction configuration.

[0223] In an embodiment of the present application, at least one set of time domain resource configuration included in the first message sent by the network device is a second scheduling restriction. The second scheduling restriction configuration is based on the TDD common uplink and downlink resource configuration, and configures the number of symbols before and after the terminal uplink symbol to be restricted for downlink transmission. For example, the first n symbols adjacent to a certain uplink symbol are configured to be prohibited from being used for downlink transmission, and / or, the last m symbols adjacent to a certain uplink symbol are configured to be prohibited from being used for downlink transmission, where n and m are integers greater than or equal to 0, and n and m can be equal or unequal.

[0224] At this time, the first terminal can determine the fourth propagation delay offset range indicator value corresponding to the fourth signal propagation delay offset range according to the fourth signal propagation delay offset range to which its own fourth signal propagation delay belongs, and then send a sixth message to the network device. The sixth message includes: the fourth propagation delay offset range indicator value corresponding to the fourth signal propagation delay, and the fourth signal propagation delay belongs to the signal propagation delay offset range corresponding to the fourth propagation delay offset range indicator value. Then, the terminal can determine the fifth time domain resource configuration according to the fourth signal propagation delay offset range and the second scheduling restriction configuration, and then use the fifth time domain resource configuration for data transmission and reception. After receiving the sixth message, the network device can determine the fifth time domain resource configuration according to the fourth signal propagation delay offset range and the second scheduling restriction configuration, and then use the fifth time domain resource configuration to schedule data for the first terminal. For example, the terminal determines the time domain position range where the uplink resource is located after the terminal performs TA compensation according to the fourth signal propagation delay offset range, and determines the fifth time domain resource configuration according to the second scheduling restriction configuration, that is, the number of symbols x before and after the time domain position range that are limited for downlink transmission, that is, the x symbols before and after the time domain position range are not scheduled for uplink and downlink time domain resources. Then, the fifth time domain resource configuration is used for data transmission and reception.

[0225] In addition, the first terminal may use the fifth time domain resource configuration to send and receive data in the next scheduling period after sending the sixth message; or, after sending the sixth message, receive a third HARQ feedback message sent by the network device, and the third HARQ feedback message is used to indicate that the sixth message has been received; and use the fifth time domain resource configuration to send and receive data in the next scheduling period after receiving the third HARQ feedback message.

[0226] In addition, the sixth message may also be: the fourth signal propagation delay. At this time, the terminal determines the sixth time domain resource configuration according to the fourth signal propagation delay and the second scheduling restriction configuration. For example, the terminal determines the time domain position range of the uplink resource after the terminal performs TA compensation at this time according to the fourth signal propagation delay, and determines the sixth time domain resource configuration according to the second scheduling restriction configuration, that is, the number of symbols x before and after the time domain position for downlink transmission, that is, the x symbols before and after the time domain position are not scheduled for uplink and downlink time domain resources. Then, the sixth time domain resource configuration is used for data transmission and reception.

[0227] In addition, the first terminal may use the sixth time domain resource configuration to send and receive data in the next scheduling period after sending the sixth message; or, after sending the sixth message, receive a third HARQ feedback message sent by the network device, and the third HARQ feedback message is used to indicate that the sixth message has been received; and use the sixth time domain resource configuration to send and receive data in the next scheduling period after receiving the third HARQ feedback message.

[0228] To help better understand the above method embodiments, the method of the present application is further illustrated below through several examples.

[0229] Example 1:

[0230] 1. The base station sends the time domain resource configuration and propagation delay reporting signaling to the terminal through the RRC message. The signaling includes the following information:

[0231] a) Propagation delay max

[0232] The maximum propagation delay value indicates the maximum time for signal transmission from the terminal to the network device (base station / TRP) that can be supported by the total number of flexible slots configured in the network. The maximum propagation delay value may be expressed in the following forms, but is not limited to: the maximum value of TA, the maximum value of propagation delay from the network device (base station / TRP) to the terminal, and the maximum value of round-trip delay (RTT) from the network device (base station / TRP) to the terminal.

[0233] b) Propagation delay offset

[0234] The propagation delay offset value indicates the absolute value of the difference between the maximum propagation delay and the minimum propagation delay that can be supported by the time domain resource configuration of the signaling configuration. The representation of the propagation delay offset value includes but is not limited to one of the following: the offset value of the TA, the offset value of the propagation delay from the network device (base station / TRP) to the terminal, and the offset value of the round-trip delay (RTT) from the network device (base station / TRP) to the terminal.

[0235] c) Time domain resource configuration, which can be expressed in the form of c1, c2 or c3 as follows. They are described below.

[0236] c1: one or more sets of TDD flexible time slots (TDD Flexible slot configuration) and the propagation delay offset range indicator value corresponding to each set of TDD flexible time slots. This representation corresponds to the first case above.

[0237] (i) A propagation delay offset range indicator value, which indicates the maximum propagation delay and the minimum propagation delay supported by this set of TDD Flexible slot configurations. The propagation delay offset range indicator value may be expressed as an integer R. Specifically,

[0238] The maximum propagation delay supported by this set of TDD Flexible slot configurations = maximum propagation delay – R*propagation delay offset value;

[0239] The minimum propagation delay supported by this set of TDD Flexible slot configurations = maximum propagation delay - (R+1) * propagation delay offset value;

[0240] (ii) TDD DL-ConfigDedicated represents a set of TDD Flexible slot downlink configurations corresponding to a certain propagation delay offset range (ie, the TDD flexible slot configuration mentioned above).

[0241] A TDD DL-ConfigDedicated representation is:

[0242]

[0243] in:

[0244] a) slotSpecificConfigurationsToAddModList indicates the Flexible slot configuration rewritten on the basis of TDDconfigcommon within the effective period of the TDD Flexible slot configuration;

[0245] b) startofDownlinksymbols means that in the slot corresponding to slotIndex, the first symbol index is the downlink symbol index;

[0246] c)nrofDownlinksymbols indicates the number of consecutive downlink symbols after the first downlink symbol index in the slot corresponding to slotIndex.

[0247] Another TDD DL-ConfigDedicated representation is:

[0248]

[0249] in:

[0250] a)nrofDownlinksymbols indicates the number of consecutive downlink symbols starting from the first downlink symbol in the slot corresponding to slotIndex.

[0251] c2: one or more scheduling restriction configurations. This representation corresponds to the second case above.

[0252] (i) A propagation delay offset range indicator value, which indicates the maximum propagation delay and the minimum propagation delay supported by this set of TDD Flexible slot configurations. The propagation delay offset range indicator value may be expressed as an integer R. Specifically,
