Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a signal transmission method, apparatus, and storage medium. Background Technology

[0002] In a communication system, network devices and terminal devices can receive or transmit periodic signals according to a certain period. Non-periodic signals or semi-continuous signals usually need to be triggered or activated before they can be received or transmitted by the terminal device.

[0003] In related technologies, network devices send trigger or activation signals to terminal devices. After receiving the signal, the terminal device determines the signal reception time or transmission time based on the predefined timing relationship between the signal trigger time and the signal transmission time.

[0191] The following explanations are provided to clarify some of the terms used in this application, so that those skilled in the art can understand them:

[0192] Reference Signaling (RS): A known signal provided by the transmitter to the receiver that serves functions such as channel estimation, channel sounding, and beam management. Reference signals include uplink reference signals and downlink reference signals. Uplink reference signals are those sent from the terminal device to the network device, while downlink reference signals are those sent from the network device to the terminal device. Types of reference signals include Sounding Reference Signals (SRS), Channel State Information-Reference Signals (CSI-RS), Tracking Reference Signals (TRS), and Positioning Reference Signals (PRS), among others.

[0193] Figure 1 A schematic diagram illustrating the application scenarios provided in the embodiments of this application, such as... Figure 1 As shown, as Figure 1 As shown, this embodiment provides a communication system 100, which includes a network device 110 and multiple terminal devices 120. This embodiment uses three of the terminal devices 120 as an example. Figure 1 In the communication system shown, for periodic signals, the network device and the terminal device can transmit the signal according to a certain period. For non-periodic and semi-continuous signals, the network device needs to send a trigger signal or activation signal to the terminal device to trigger or activate the terminal device to receive / transmit non-periodic and / or semi-continuous signals.

[0194] For example, in a scenario where terminal device 120 communicates with network device 110, network device 110 can send aperiodic downlink reference signals to terminal device 120 as needed for channel state acquisition, beam management, synchronization, and channel estimation of the downlink channel between network device 110 and terminal device 120. Alternatively, terminal device 120 can send aperiodic uplink reference signals to network device 110 for channel state acquisition, beam management, synchronization, and channel estimation of the uplink channel between network device 110 and terminal device 120.

[0195] In related technologies, taking aperiodic or semi-persistent reference signals as an example, the network device configures reference signal resources to the terminal device and sends a trigger signal or activation signal to the terminal device. After receiving the trigger signal or activation signal, the terminal device determines the reception / transmission time of the reference signal according to the timing relationship between the predefined or configured signal trigger time and the signal reception / transmission time. The reference signal is then received / transmitted during its designated reception / transmission time.

[0196] Taking the Sounding Reference Signal (SRS) as an example, in the New Radio (NR) system of a third-generation mobile communication system, network equipment configures an aperiodic SRS resource set and the transmission time offset of the SRS resources in the aperiodic SRS resource set for terminal equipment through Radio Resource Control (RRC) signals, and triggers the transmission of aperiodic SRS resources through Downlink Control Information (DCI) signals.

[0197] For example, a network device triggers an SSR signal for an aperiodic SRS resource set to a terminal device via a DCI signal in slot n. All SRS resources within this resource set are in the slot. Send. Where K is the transmission slot offset (or transmission time offset), μ SRS and μ PDCCH These represent the subcarrier spacing values ​​of the triggered SSR signal and the Physical Downlink Control Channel (PDCCH) carrying the trigger signal, respectively. In this embodiment of the invention, for ease of description, we assume μ... SRS and μ PDCCH Same. It should be understood that if μ SRS and μ PDCCH Unlike other factors, this may need to be taken into account when determining the actual transmission location of SRS.

[0198] In the above method, RRC signaling is semi-static signaling, and the timing relationship between the signal triggering time and the signal reception / transmission time configured by RRC signaling is singular, resulting in an inflexible signal triggering and transmission process. For example, in Time Division Duplexing (TDD) mode, if the signal transmission time slot (or signal transmission time) is n+n... offset For downlink time slots, then in signal transmission time slot n+n offset Uplink reference signal transmission is not possible if signal transmission time slot n+n offset If it is the uplink time slot, then in the signal transmission time slot n+n offset Downlink reference signal transmission is not possible. Where n offset This is the transmission time slot offset.

[0199] To avoid situations where the reference signal cannot be transmitted, the transmission time of the trigger signal needs to be limited, such as by restricting the time domain position of the DCI signal, which reduces the flexibility of trigger signal transmission. Table 1 shows examples of signal transmission with different transmission time slot offsets when the uplink and downlink time slots are configured such that every five time slots is DDFUU. Here, D represents the downlink time slot, in which only downlink signals can be transmitted; U represents the uplink time slot, in which only uplink signals can be transmitted; and F represents a special time slot, in which both uplink and downlink signals can be transmitted. In Table 1, the PDCCH carries the trigger signal, which is sent from the network device to the terminal device. Therefore, the trigger signal is a downlink signal and can only be transmitted in time slots D or F. The probe reference signal (SRS) is an uplink reference signal, and therefore can only be transmitted in time slots F or U. The transmission time slot offsets of 0, 1, 2, 3, and 4 represent the number of time slots between the trigger signal and the reference signal, respectively.

[0200] Table 1

[0201]

[0202] As shown in Table 1, to complete SRS triggering and transmission within 5 time slots, when the transmission time slot offset is 1, the PDCCH signal used to trigger SRS can be sent in the second downlink time slot or a special time slot; when the transmission time slot offset is 2, the PDCCH signal can be sent in the first downlink time slot, the second downlink time slot, or a special time slot; when the transmission time slot offset is 3, the PDCCH signal can be transmitted in the first downlink time slot or the second downlink time slot; and when the transmission time slot offset is 4, the PDCCH signal can be transmitted in the first downlink time slot. The relatively simple transmission time slot offset restricts the time slot location of the PDCCH signal, and the flexibility of PDCCH and SRS signal transmission needs to be improved.

[0203] To address the aforementioned problems, embodiments of this application provide a signal transmission method, apparatus, and storage medium. In the signal transmission method provided in this application, the first information sent by the network device to the terminal device not only triggers the terminal device to receive or transmit a target signal but is also associated with a first trigger state. Based on a predetermined correspondence between multiple trigger states and transmission time offsets, the terminal device can determine the target transmission time offset associated with the first trigger state, thereby determining the target transmission time of the target signal and receiving or transmitting the target signal according to the target transmission time. Therefore, by setting multiple trigger states and corresponding them to transmission time offsets, embodiments of this application allow the network device to select different transmission time offsets by triggering different trigger states, thereby flexibly controlling the target transmission time of the target signal and effectively improving the flexibility of signal transmission.

[0204] The methods and apparatus provided in the embodiments of this application are based on the same concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0205] Figure 2 This is a schematic flowchart of a signal transmission method provided in an embodiment of this application. The method in this embodiment can be executed by the aforementioned terminal device.

[0206] like Figure 2 As shown, the method in this embodiment may include:

[0207] S201, Receive the first information sent by the network device.

[0208] The first piece of information is used to trigger the terminal device to receive or send the target signal.

[0209] Optionally, the target signal can be any of the following signals: Physical Uplink Share Channel (PUSCH) signal, Physical Uplink Control Channel (PUCCH) signal, Physical Random Access Channel (PRACH) signal, Physical Downlink Share Channel (PDSCH) signal, or Physical Uplink Control Channel (Phase I).

[0210] Optionally, the first information is used to trigger the interrupt device to receive or transmit the target signal, and may include: the first information being used to trigger the terminal device to receive or transmit the signal resources of the target signal; or, the first information being used to receive or transmit the signal of the signal resource set to which the signal resources of the target signal reside. For example, for an uplink reference signal SRS, the first signal is used to trigger the terminal device to transmit the SRS, that is, to trigger the terminal device to transmit the SRS signal resources or the SRS signal resources. The signal resource set includes multiple signal resources, and the signal resources include parameters such as signal bandwidth and frequency domain.

[0211] The first information is associated with the first trigger state.

[0212] Optionally, the association between trigger information and trigger status can be pre-set, or the network device can pre-configure the association between trigger information and trigger status to the terminal device. Here, the first information is the trigger information, and the first trigger status is the trigger status. The first trigger status is the trigger status associated with the first information in the association between trigger information and trigger status.

[0213] Optionally, the association between trigger information and trigger state can be achieved through a mapping between trigger values ​​and trigger states. The trigger information includes one or more trigger values. The mapping between trigger values ​​and trigger states can be preset, or the network device can pre-configure the mapping between trigger values ​​and trigger states to the terminal device, with different trigger values ​​corresponding to different trigger states. In the mapping between trigger values ​​and trigger states, the trigger value in the first information corresponds to the first trigger state.

[0214] Multiple trigger states can be pre-configured with associations between aperiodic signals and / or semi-persistent signals, or the network device can pre-configure multiple trigger states with associations between aperiodic signals and / or semi-persistent signals to the terminal device.

[0215] In this embodiment, the terminal device receives the first information sent by the network device and can determine the first trigger state associated with the first information. Among the association relationships between multiple trigger states and aperiodic signals and / or semi-persistent signals, the terminal device determines the aperiodic signal and / or semi-persistent signal associated with the first trigger state. The aperiodic signal and / or semi-persistent signal associated with the first trigger state is the target signal, so that the terminal device can subsequently receive or send the target signal.

[0216] Optionally, the association between multiple trigger states and aperiodic signals and / or semi-persistent signals can be a correspondence between multiple trigger states and aperiodic signals and / or semi-persistent signals. The correspondence between multiple trigger states and aperiodic signals and / or semi-persistent signals can be preset, or the network device can configure the correspondence between multiple trigger states and aperiodic signals and / or semi-persistent signals to the terminal device.

[0217] Optionally, the association between multiple trigger states and aperiodic and / or semi-persistent signals can be achieved by pre-setting the correspondence between multiple trigger states and signal resources, or by the network device configuring the correspondence between multiple trigger states and signal resources to the terminal device. One trigger state can correspond to one or more signal resources. In other words, this is achieved by the network device setting corresponding trigger states for multiple signal resources, and the trigger state of each signal resource can be configured in the configuration information of each signal resource.

[0218] Optionally, the association between multiple trigger states and aperiodic and / or semi-persistent signals can be achieved by pre-setting the correspondence between multiple trigger states and signal resource sets, or by the network device configuring the correspondence between multiple trigger states and signal resource sets to the terminal device. One trigger state can correspond to one or more signal resource sets. In other words, this is achieved by the network device setting corresponding trigger states for multiple signal resource sets, and the trigger state of each signal resource set can be configured in the configuration information of each signal resource set.

[0219] Furthermore, network devices can configure multiple signal resource sets and set corresponding trigger states for terminal devices using one or more signals.

[0220] As an example, a network device can send configuration information of an SRS resource set to a terminal device. The configuration information of the SRS resource set includes a list of SRS resources, the trigger state corresponding to the SRS resource set, and the transmission slot offset corresponding to the trigger state.

[0221] S202. Based on the first information, determine the first trigger state associated with the first information.

[0222] In this embodiment, after receiving the first information, the first trigger state associated with the first information can be determined from the association relationship between trigger information and trigger state. The association relationship between trigger information and trigger state is as described above and will not be repeated here.

[0223] The number of first trigger states can be one or more. If there is only one trigger state associated with the first information in the association between trigger information and trigger states, then that single trigger state is determined as the first trigger state. If there are multiple trigger states associated with the first information in the association between trigger information and trigger states, then all of those trigger states are determined as the first trigger state.

[0224] S203. Based on the pre-determined correspondence between multiple trigger states and transmission time offsets, determine the target transmission time offset associated with the first trigger state.

[0225] In this embodiment, multiple trigger states correspond to transmission time offsets. Therefore, the network device can determine the first information to send to the terminal device based on the correspondence between multiple trigger states and transmission time offsets, and the association between trigger states and trigger information, rather than relying on a fixed single transmission time offset. Compared to a single transmission time offset, the correspondence between multiple trigger states and transmission time offsets provided in this embodiment offers richer transmission time offsets and trigger states for signal transmission between the network device and the terminal device, providing a more flexible method for selecting transmission time offsets.

[0226] Optionally, different trigger states correspond to different transmission time offsets, or at least two trigger states correspond to the same transmission time offset, which helps to improve the diversity of the correspondence between trigger states and transmission time offsets.

[0227] Optionally, multiple mappings between trigger states and transmission time offsets can be pre-configured, or the network device can pre-configure these mappings to the terminal device. Pre-configuring these mappings by the network device improves the flexibility of the mappings.

[0228] Optionally, the correspondence between multiple trigger states and transmission time offsets includes the following: the correspondence between multiple trigger states of the signal resource set containing the signal resource corresponding to the target signal and the transmission time offset; the correspondence between multiple trigger states of the signal resource corresponding to the target signal and the transmission time offset; and the correspondence between multiple trigger states of the target signal and the transmission time offset. Specifically, the multiple trigger states of the signal resource set containing the signal resource corresponding to the target signal are those that correspond to the signal resource set containing the target signal resource; the multiple trigger states of the signal resource corresponding to the target signal are those that correspond to the signal resource corresponding to the target signal, and this correspondence can be referred to the aforementioned content; and the trigger states of the target signal are those that correspond to the target signal. These correspondences can be referred to the aforementioned content and will not be repeated here.

[0229] As an example, when the target signal is SRS, the signal resources are SRS resources, and the signal resource set is the SRS resource set. When the target signal is CSI-RS, the signal resources are CSI-RS resources, and the signal resource set is the CSI-RS resource set.

[0230] In this embodiment, based on the correspondence between multiple trigger states and transmission time offsets, the transmission time offset corresponding to the first trigger state is obtained, the first transmission time offset corresponding to the first trigger state is obtained, and the target transmission time offset associated with the first trigger state is determined according to the first transmission time offset.

[0231] S204. Determine the target transmission time of the target signal based on the reception time of the first information and the target transmission time offset.

[0232] The target transmission time offset is the time interval between the reception time of the first information and the target transmission time of the target signal. The target transmission time of the target signal is also the transmission time of the target signal. For the terminal device, when the target signal is a downlink signal, the target transmission time of the target signal is the reception time of the target signal; when the target signal is an uplink signal, the target transmission time of the target signal is the transmission time of the target signal.

[0233] Optionally, both the transmission time offset and the target transmission time offset are in units of time slots. In other words, the transmission time offset is the transmission time slot offset, and the target transmission time offset is the target transmission time slot offset. Similarly, the reception time of the first information is the reception time slot of the first information, the target transmission time is the target transmission time slot, and the time interval between the reception time of the first information and the target transmission time is the number of time slots between the reception time slot of the first information and the target transmission time slot.

[0234] In this embodiment, since the target transmission time offset is the time interval between the reception time of the first information and the target transmission time of the target signal, the target transmission time of the target signal can be obtained by summing the reception time of the first information and the target transmission time offset.

[0235] S205. Receive or send the target signal according to the target transmission time.

[0236] In this embodiment, when the target signal is a downlink signal, the terminal device receives the target signal sent by the network device during the target transmission time. When the target signal is an uplink signal, the terminal device sends the target signal to the network device during the target transmission time.

[0237] Optionally, if there is a signal with higher priority than the target signal waiting to be sent or received between the network device and the terminal device, and the time for the target signal to be sent or received overlaps with the target transmission time, then the reception or transmission of the target signal is stopped; otherwise, the reception or transmission of the target signal is performed during the target transmission time, ensuring the transmission and reception of different signals between the network device and the terminal device.

[0238] In this embodiment, the network device sends first information to the terminal device to trigger the terminal device to receive / send a target signal. The terminal device determines the target transmission time offset based on the association between the first information and the first trigger state and the correspondence between multiple trigger states and transmission time gaps. Based on the target transmission time offset, the target transmission time is determined, and the target signal is received or sent during the target transmission time. This improves the flexibility of target signal triggering and transmission, thereby improving the transmission effect of the target signal.

[0239] In some embodiments, the target signal is a reference signal, which includes an uplink reference signal and / or a downlink reference signal. Both the uplink and / or downlink reference signals can include aperiodic and / or semi-continuous signals. Further, the reference signal includes one or more of the following: SRS, CSI-RS, TRS, and PRS. The reference signal may also include a Channel State Information (CIS-IM) signal.

[0240] In some embodiments, the target transmission time offset associated with the first trigger state may be the first transmission time offset corresponding to the first trigger state in a correspondence between multiple trigger states and transmission time offsets. Therefore, as Figure 3As shown, one possible implementation of S203 includes: S2031, obtaining the first transmission time offset corresponding to the first trigger state according to the predetermined correspondence between multiple trigger states and transmission time offsets; S2032, determining the first transmission time offset corresponding to the first trigger state as the target transmission time offset.

[0241] Specifically, in the correspondence between multiple trigger states and transmission time offsets, the first transmission time offset corresponding to the first trigger state is found, and this first transmission time offset is determined as the target transmission time offset. Therefore, the target transmission time can be determined directly based on the first time offset corresponding to the first trigger state and the reception time of the first information.

[0242] In some embodiments, the target transmission time offset associated with the first trigger state may include a first transmission time offset and a reference transmission time offset corresponding to the first trigger state in a correspondence between multiple trigger states and transmission time offsets. Therefore, as Figure 4 As shown, one possible implementation of S203 includes: S2033, obtaining a first transmission time offset corresponding to the first trigger state according to a predetermined correspondence between multiple trigger states and transmission time offsets; S2034, determining a target transmission time offset according to the first transmission time offset and a reference transmission time offset.

[0243] Specifically, when determining the target transmission time offset based on the first transmission time offset and the reference transmission time offset, the target transmission time offset can be calculated by summing or weighted summing the first and reference transmission time offsets. This divides the target transmission time offset into two parts: the transmission time offset and the reference transmission time offset, thus improving the flexibility of the target transmission time.

[0244] Optionally, the correspondence between multiple trigger states and transmission time offsets can be a predefined correspondence, such as a predefined correspondence in a communication protocol, where the reference transmission time offset is pre-sent by the network device to the terminal device. The network device can indicate the same reference transmission time offset for all trigger states, while different trigger states can correspond to different transmission time offsets. This simplifies the operation of the network device and improves the flexibility of setting the target transmission time offset by combining the transmission time offsets corresponding to multiple trigger states.

[0245] Conversely, the correspondence between multiple trigger states and reference transmission time offsets can be a predefined correspondence, where the network device sends the correspondence between multiple trigger states and transmission time offsets to the terminal device in advance, and multiple trigger states correspond to the same transmission time offset.

[0246] Optionally, the correspondences between multiple trigger states and transmission time offsets, and between multiple trigger states and reference transmission time offsets, can all be pre-sent to the terminal device by the network device (i.e., after determining the target transmission time offset). These can be sent using the same signal or different signals. Therefore, by configuring multiple trigger states to correspond to transmission time offsets in the terminal device, the network device specifies a portion of the target transmission time offset. By configuring multiple trigger states to correspond to reference transmission time offsets in the terminal device, it guides the determination of another portion of the target transmission time offset. Combining these two portions of the value to determine the target transmission time offset improves the flexibility of target transmission time offset determination, thereby enhancing the flexibility of signal transmission.

[0247] Optionally, before determining the target transmission time offset based on the first transmission time offset and the reference transmission time offset, a second piece of information sent by the network device can be received. This second piece of information indicates the reference transmission time offset or indicates the correspondence between multiple trigger states and the reference transmission time offset. Different trigger states correspond to different reference transmission time offsets, or at least two trigger states correspond to the same reference transmission time offset, meaning at least two trigger states can share a single reference transmission time offset.

[0248] Optionally, before determining the target transmission time offset based on the first transmission time offset, a fifth piece of information sent by the network device can be received. This fifth piece of information indicates the correspondence between multiple trigger states and transmission time offsets. Different trigger states correspond to different transmission time offsets, or at least two trigger states correspond to the same transmission time offset, meaning at least two trigger states can share a single transmission time offset.

[0249] For example, both the second and fifth information are transmitted using RRC signaling, such as using the same RRC signaling or using different RRC signaling; or, both the second and fifth information are transmitted using Medium Access Control-Control Element (MAC-CE) signaling, such as using the same MAC-CE signaling or using different MAC-CE signaling; or, one of the second and fifth information uses RRC signaling and the other uses MAC-CE signaling; or, one of the second and fifth information uses RRC signaling and the other uses DCI signaling; or, both the second and fifth information are transmitted using DCI signaling, such as using the same DCI signaling or using different DCI signaling.

[0250] Based on "before determining the target transmission time offset according to the first transmission time offset and the reference transmission time offset, second information can be received from the network device, the second information being used to indicate the reference transmission time offset or to indicate the correspondence between multiple trigger states and the reference transmission time offset", Figure 5 This is a schematic flowchart of a signal transmission method provided in another embodiment of this application.

[0251] like Figure 5 As shown, the method in this embodiment may include:

[0252] S501, The network device sends second information to the terminal device. The second information is used to indicate the reference transmission time offset or to indicate the correspondence between multiple trigger states and the reference transmission time offset.

[0253] S502, The network device sends first information to the terminal device, the first information being used to trigger the terminal device to receive or send the target signal.

[0254] The number of times S501 and S502 are executed can be interchanged.

[0255] S503. The terminal device determines the first trigger state associated with the first information based on the first information.

[0256] S504. The terminal device obtains the first transmission time offset corresponding to the first trigger state based on the correspondence between multiple trigger states and transmission time offsets.

[0258] S506. The terminal device determines the target transmission time of the target signal based on the reception time of the first information and the target transmission time offset.

[0259] Specifically, if the first information is used to trigger the terminal device to receive the target signal, then S507 is executed; if the first information is used to trigger the terminal device to send the target signal, then S508 is executed.

[0260] S507. The terminal device receives the target signal sent by the network device according to the target transmission time.

[0261] S508: The terminal device sends the target signal to the network device according to the target transmission time.

[0262] Specifically, the implementation process and technical effects of S501 to S508 can be referred to the content of the aforementioned embodiments, and will not be repeated here.

[0263] Based on "the fifth information sent by the network device before determining the target transmission time offset according to the first transmission time offset, the fifth information is used to indicate the correspondence between multiple trigger states and transmission time offsets", Figure 6 This is a schematic flowchart illustrating a signal transmission method provided in another embodiment of this application. Figure 6 As shown, the method in this embodiment may include:

[0264] S601. The network device sends the fifth information to the terminal device. The fifth information is used to indicate the correspondence between multiple trigger states and transmission time offsets.

[0265] S602. The network device sends first information to the terminal device, which is used to trigger the terminal device to receive or send the target signal.

[0266] The number of times S601 and S602 are executed can be interchanged.

[0267] S603. The terminal device determines the first trigger state associated with the first information based on the first information.

[0268] S604. The terminal device obtains the first transmission time offset corresponding to the first trigger state based on the correspondence between multiple trigger states and transmission time offsets.

[0269] S605. The terminal device determines the target transmission time offset based on the first transmission time offset and the reference transmission time offset.

[0270] S606. The terminal device determines the target transmission time of the target signal based on the reception time of the first information and the target transmission time offset.

[0271] Specifically, if the first information is used to trigger the terminal device to receive the target signal, then S607 is executed; if the first information is used to trigger the terminal device to send the target signal, then S608 is executed.

[0272] S607. The terminal device receives the target signal sent by the network device according to the target transmission time.

[0273] S608. The terminal device sends the target signal to the network device according to the target transmission time.

[0274] Specifically, the implementation process and technical effects of S601 to S608 can be referred to the content of the foregoing embodiments, and will not be repeated here.

[0275] Before determining the target transmission time offset based on the first transmission time offset and the reference transmission time offset, second information sent by the network device can be received. This second information is used to indicate the reference transmission time offset or to indicate the correspondence between multiple trigger states and the reference transmission time offset. This can be combined with the embodiment where "before determining the target transmission time offset based on the first transmission time offset, fifth information sent by the network device can be received. This fifth information is used to indicate the correspondence between multiple trigger states and the transmission time offset." Refer to the following example. Figure 5 , Figure 6 The combination of the embodiments shown is not described in detail.

[0276] In some embodiments, the predetermined correspondence between multiple trigger states and transmission time offsets includes multiple sets of correspondences, that is, multiple sets of correspondences between multiple trigger states and transmission time offsets. For example, in the first set of correspondences, the transmission time offset corresponding to trigger state 1 is a1, and the transmission time offset corresponding to trigger state 2 is a2. In the second set of correspondences, the transmission time offset corresponding to trigger state 1 is b1, and the transmission time offset corresponding to trigger state 2 is b2.

[0277] Based on the situation where there are multiple sets of multiple trigger states and transmission time offsets in the pre-determined correspondence between multiple trigger states and transmission time offsets, Figure 7 This is a schematic flowchart of a signal transmission method provided in another embodiment of this application.

[0278] like Figure 7 As shown, the method in this embodiment may include:

[0279] S701. The network device sends the fifth information to the terminal device. The fifth information is used to indicate the correspondence between multiple trigger states and transmission time offsets.

[0280] S702. The network device sends first information to the terminal device, which is used to trigger the terminal device to receive or send the target signal.

[0281] The execution order of S701 and S702 can be interchanged.

[0282] S703. The network device sends third information to the terminal device. The third information is used to select one set of multiple trigger states and transmission time offset correspondences from multiple pre-determined correspondences.

[0283] The execution order of S702 and S703 can be interchanged.

[0284] The third information is used to indicate the selected set of multiple trigger states and transmission time offsets from the multiple sets of correspondences between trigger states and transmission time offsets indicated by the fifth information. For example, if there are multiple sets of trigger states and transmission time offsets in groups A, B, and C, the third information can instruct the terminal device to select group A, group B, or group C.

[0285] Optionally, the fifth and third information can be DCI signals.

[0286] Optionally, the third information and the first information can be carried in the same DCI signal. The third information and the first information can be in the same information domain or different information domains.

[0287] Optionally, the third information can also be the MAC-CE signal.

[0288] S704. The terminal device determines the first trigger state associated with the first information based on the first information.

[0289] S705. The terminal device determines the target transmission time offset associated with the first trigger state based on the correspondence between the multiple trigger states selected by the third information and the transmission time offset.

[0290] S706. The terminal device determines the target transmission time of the target signal based on the reception time of the first information and the target transmission time offset.

[0291] Specifically, if the first information is used to trigger the terminal device to receive the target signal, then S707 is executed; if the first information is used to trigger the terminal device to send the target signal, then S708 is executed.

[0292] S707: The terminal device receives the target signal sent by the network device according to the target transmission time.

[0293] S708: The terminal device sends the target signal to the network device according to the target transmission time.

[0294] Specifically, the implementation process and technical effects of S701, S704 to S707 can be referred to the content of the foregoing embodiments, and will not be repeated here.

[0295] In this embodiment, the terminal device is triggered to receive or send the target signal by the first information, and a set is selected from multiple sets of correspondences between trigger states and transmission time offsets by the third information. This effectively improves the flexibility of determining the target transmission time offset, thereby improving the flexibility of the target transmission time and the flexibility of signal transmission.

[0296] In some embodiments, in the correspondence between multiple trigger states and transmission time offsets, a trigger state may correspond to one or more transmission time offsets. For example, one trigger state may correspond to transmission time offset a1 and transmission time offset a2. Further, a first trigger state may correspond to multiple transmission time offsets, or in other words, a first trigger state may correspond to multiple first transmission time offsets.

[0297] Based on the situation where the first trigger state corresponds to multiple transmission time offsets. Figure 8 This is a schematic flowchart of a signal transmission method provided in another embodiment of this application.

[0298] like Figure 8 As shown, the method in this embodiment may include:

[0299] S801. The network device sends first information to the terminal device, which is used to trigger the terminal device to receive or send the target signal.

[0300] S802, the network device sends fourth information to the terminal device, the fourth information being used to select a first transmission time offset from multiple transmission time offsets corresponding to the first trigger state associated with the first information.

[0301] The execution order of S801 and S802 can be interchanged.

[0302] The fourth piece of information is used to indicate the selection of a first transmission time offset from among multiple transmission time offsets corresponding to the first trigger state. For example, if the first trigger state corresponds to transmission time offsets b1 and b2, the third piece of information can instruct the terminal device to select either b1 or b2.

[0303] S803. The terminal device determines the first trigger state associated with the first information based on the first information.

[0304] S804. The terminal device determines the target transmission time offset based on the first transmission time offset corresponding to the first trigger state indicated by the fourth information.

[0305] S805. The terminal device determines the target transmission time of the target signal based on the reception time of the first information and the target transmission time offset.

[0306] Specifically, if the first information is used to trigger the terminal device to receive the target signal, then S806 is executed; if the first information is used to trigger the terminal device to send the target signal, then S807 is executed.

[0307] S806. The terminal device receives the target signal sent by the network device according to the target transmission time.

[0308] S807. The terminal device sends the target signal to the network device according to the target transmission time.

[0309] Specifically, the implementation process and technical effects of S801, S803, S804 to S807 can be referred to the content of the foregoing embodiments, and will not be repeated here.

[0310] In this embodiment, the terminal device is triggered to receive or send the target signal by the first information, and a transmission time offset is selected from multiple transmission time offsets corresponding to the first trigger state by the fourth information.

The first information is associated with a first trigger state. In a predetermined correspondence between multiple trigger states and transmission time offsets, the first trigger state is associated with the target transmission time offset.

[0314] In this embodiment, S901 can be referred to the content of the foregoing embodiment, and will not be repeated here.

[0315] S902, Obtain the target transmission time of the target signal;

[0316] In this embodiment, the network device can determine the target transmission time of the target signal and, based on the target transmission time and a predetermined correspondence between multiple trigger states and transmission time offsets, determine the transmission time of the first information. Therefore, the execution order of S902 and S901 can be interchanged.

[0317] S903. Send or receive the target signal according to the target transmission time.

[0318] In this embodiment, S903 can be referred to the content of the foregoing embodiment, and will not be repeated here.

[0319] Optionally, the network device sends a second piece of information to the terminal device. The second piece of information is used to indicate a reference transmission time offset, and the reference transmission time offset and the target transmission time offset are associated with the target transmission time of the target signal.

[0320] Optionally, the correspondence between multiple trigger states and transmission time offsets includes the following: the correspondence between multiple trigger states and transmission time offsets of the signal resource set where the signal resource corresponding to the target signal is located; the correspondence between multiple trigger states and transmission time offsets of the signal resource corresponding to the target signal; and the correspondence between multiple trigger states and transmission time offsets of the target signal.

[0321] Optionally, the predetermined correspondence between multiple trigger states and transmission time offsets includes multiple sets of correspondences between multiple trigger states and transmission time offsets; before transmitting the target signal according to the target transmission time, it further includes: sending third information to the terminal device, the third information being used to select one set of correspondences between multiple trigger states and transmission time offsets from the multiple sets of correspondences between multiple trigger states and transmission time offsets.

[0322] Optionally, the first trigger state corresponds to multiple transmission time offsets; before transmitting the target signal according to the target transmission time, the method further includes: sending fourth information to the terminal device, the fourth information being used to select the first transmission time offset from the multiple transmission time offsets corresponding to the first trigger state.

[0323] Optionally, before sending the first information to the terminal device, the method further includes sending a fifth piece of information to the terminal device, wherein the fifth piece of information is used to indicate the correspondence between multiple trigger states and transmission time offsets.

[0324] In this embodiment, the implementation details on the network device side can be referred to the description in the foregoing embodiments, and will not be repeated here.

[0325] based on Figures 2 to 9 The embodiments shown, taking SRS as an example, provide the following exemplary description of the signal transmission method provided in this application:

[0326] (1) During the information resource set configuration phase (including configuring the information resource set and the correspondence between multiple trigger states and transmission time offsets), the network device can use RRC signaling to configure one or more aperiodic SRS resource sets. In the NR system, the resource type in the RRC signaling (the SRS resource set with resourceType "aperiodic" is an aperiodic SRS resource set). Each SRS resource set includes one or more SRS resources. The network device configures one or more trigger states and the corresponding transmission time slot offsets for each SRS resource set.

[0327] (2) During the signal triggering phase (including the network device sending the first information to the terminal device), the network device triggers an aperiodic SRS resource set through the SRS request field in the DCI signal. The DCI is carried by the PDCCH and sent to the terminal device. The DCI format can be, for example, DCI format 0_1, DCI format 0_2, DCI format 1_1, DCI format 1_2, or DCI format 2_3. The value of the SRS request field indicates which SRS resources in the SRS resource set are configured with trigger states and are thus triggered; that is, the value of the SRS request field is the trigger value mentioned in the first information in the aforementioned embodiments. The values ​​of the SRS request field correspond one-to-one with the trigger states. For example, the correspondence between the values ​​of the SRS request field and the trigger states is shown in Table 2 below:

[0328] Table 2

[0329] Values ​​of the SRS request field State (Non-triggered state + Triggered state) 00 No aperiodic SRS resource set was triggered. 01 The SRS resource set with the trigger parameter configured to 1 is triggered. 10 The SRS resource set with the trigger parameter configured to 2 is triggered. 11 The SRS resource set with the trigger parameter configured as 3 is triggered.

[0330] In Table 2, the SRS request field has a bit width of 2 bits and four possible values. When the value is "00", it indicates that no non-periodic SRS resource has been triggered, and this state can be considered as a non-triggered state. The values ​​"01", "10", and "11" correspond to different triggering states and are used to trigger different sets of SRS resources.

[0331] (3) Assume an SRS resource set is configured with two trigger states: trigger state 1 and trigger state 2, where trigger state 1 corresponds to transmission time slot offset k1 and trigger state 2 corresponds to transmission time slot offset k2. If the network device sends a DCI to the terminal device in time slot n, and the SRS request field of the DCI is "01", then based on the correspondence shown in Table 2, the terminal device knows that the SRS resource set with trigger state configured as 1 is triggered for transmission in time slot n+k1. If the network device sends a DCI to the terminal device in time slot n, and the SRS request field of the DCI is "10", then based on the correspondence shown in Table 2, the terminal device knows that the SRS resource set with trigger state configured as 2 is triggered for transmission in time slot n+k2.

[0332] (4) Assuming that part of the transmission time slot offset corresponding to the trigger state of the SRS resource set is configured in the configuration information of the SRS resource set, and the other part is configured in other signals (such as RCC signal, MAC-CE signal, DCI signal, or a combination of one or more of these three signals), that is, in the above embodiment, the network device can send the reference transmission time offset to the terminal device through other signaling.

[0333] At this point, if the transmission slot offset in the configuration information of an SRS resource set is k, and the SRS resource set is configured with two trigger states: trigger state 1 and trigger state 2, the transmission slot offset corresponding to trigger state 1 is k1, and the transmission slot offset corresponding to trigger state 2 is k2. Assuming the network device sends a DCI to the terminal device in slot n, and the SRS request field of the DCI is "01", then based on the correspondence shown in Table 2, the terminal device knows that the SRS resource set with trigger state configured as 1 is triggered for transmission in slot n+k+k1. Assuming the network device sends a DCI to the terminal device in slot n, and the SRS request field of the DCI is "10", then based on the correspondence shown in Table 2, the terminal device knows that the SRS resource set with trigger state configured as 2 is triggered for transmission in slot n+k+k2.

[0334] (5) Assume that the trigger state 1 of an SRS resource set is configured with two time slot offsets, corresponding to transmission time slot offset k1 and transmission time slot offset k2 respectively. The correspondence between trigger state 1 and these two transmission time slot offsets is configured in the configuration information of the SRS resource set.

[0335] At this time, if the network device indicates the slot offset selection information of the SRS resource set to the terminal device through the MAC-CE signal, the slot offset selection information is the slot offset value selected by each trigger state of the SRS resource set. Assuming that trigger state 1 selects the transmission slot offset k1, the terminal device knows that the SRS resource set with trigger state configured as 1 is triggered to transmit in slot n+k1.
