Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a wireless communication method, wireless communication node, wireless communication device, electronic device, computer-readable storage medium, and computer program product. Background Technology

[0002] A reference signal is a pre-defined signal used by both communicating parties in a wireless communication system for various measurements and estimations. The receiving party can obtain at least one of the following from the reference signal: channel state, synchronization reference, and interference information. These play crucial roles in the communication system. For example, the Sounding Reference Signal (SRS) is a signal used for uplink channel measurement in cellular communication systems, such as 5G New Radio (NR) systems. It helps the base station obtain channel state information. The base station can schedule uplink signals based on the obtained channel state information, or further utilize the reciprocity between uplink and downlink channels to obtain downlink channel measurements based on the uplink channel measurement results, and then schedule downlink signals accordingly.

[0003] In related technologies, a reference signal is restricted to transmission within a single time slot. Since a single-time-slot reference signal only reflects the instantaneous channel state, it is difficult to characterize the dynamic changes in subsequent time slots. It is also unfavorable for scenarios with power constraints or low signal-to-noise ratios, where repeated transmission across multiple time-domain symbols or frequency hopping is possible. Problems exist such as inaccurate and untimely channel estimation, limited scheduling flexibility, and inability to adapt to changing channel conditions. Not only the reference signal, but also the channel signal itself, although it can be transmitted across multiple time slots, suffers from inflexible parameter configuration, leading to inflexible base station scheduling and failing to effectively reduce power consumption at both the base station and terminal sides.

[0004] Therefore, how to transmit signals so that the receiver can obtain channel information more timely and accurately, and how to improve the reception performance of signals that are continuously retransmitted or frequency-hopping in scenarios where the transmitter's power is limited or the signal-to-noise ratio is low, are urgent problems to be solved. Summary of the Invention

[0005] This application provides a wireless communication method, wireless communication node, wireless communication device, electronic device, computer-readable storage medium, and computer program product. By configuring a reference signal to occupy multiple time domain symbols in multiple time slots through parameter configuration, the signal can be transmitted on multiple time domain symbols in at least two time slots. The transmission includes at least one of the following: sending and receiving. That is, a signal can be sent across time slots, which can improve the receiving performance of the receiver, reduce the power consumption of both parties in communication, and improve the scheduling flexibility of the signal.

[0006] In a first aspect, embodiments of this application provide a wireless communication method applied to a first communication node, comprising: the first communication node transmitting a signal in a signal unit on multiple time-domain symbols in at least two time slots, wherein the signal unit is a signal resource or a group of signal resources; the group of signal resources includes at least one signal resource, and the signal resource includes at least one signal port.

[0007] Secondly, embodiments of this application provide a wireless communication method applied to a second communication node, comprising: the second communication node receiving a signal in a signal unit on multiple time-domain symbols in at least two time slots; wherein the signal unit is a signal resource or a group of signal resources; the group of signal resources includes at least one signal resource, and the signal resource includes at least one signal port.

[0008] Thirdly, embodiments of this application provide a communication node that performs communication with another communication node by executing the communication method described in the first aspect, or performs communication with another communication node by executing the communication method described in the second aspect.

[0009] Fourthly, embodiments of this application provide an electronic device, including: one or more processors; and a memory storing one or more programs thereon, which, when executed by the one or more processors, cause the one or more processors to implement the wireless communication method as described in the first or second aspect.

[0010] Fifthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the wireless communication method as described in the first or second aspect.

[0011] In a sixth aspect, embodiments of this application provide a computer program product, including a computer program or computer instructions, characterized in that the computer program or computer instructions are stored in a computer-readable storage medium, a processor of a computer device reads the computer program or computer instructions from the computer-readable storage medium, and the processor executes the computer program or computer instructions to cause the computer device to perform the wireless communication method as described in the first or second aspect.

[0012] This application transmits signals from a single signal unit across multiple time-domain symbols in at least two time slots. Firstly, this effectively improves the receiver's signal reception performance, enabling more timely and accurate acquisition of channel information. It also enhances the reception performance of continuously repetitive or frequency-hopping signals in scenarios with limited transmitter power or low signal-to-noise ratios. Secondly, it concentrates the active time of both communicating parties, allowing them to remain in a sleep state for longer periods, thus saving power consumption. Thirdly, the flexibility of parameter configuration effectively improves the flexibility of base station signal scheduling, increases the utilization of fragmented resources, enhances spectrum efficiency, reduces communication latency, and supports more services. Fourthly, by establishing correlations between signals in multiple time slots, the transmitter's transmission parameters meet agreed-upon conditions across multiple time slots, allowing the receiver to perform joint reception based on signals from multiple time slots, thereby improving reception performance.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] In this application, the terms "exemplarily" and "preferredly" are used to indicate that they are examples, illustrations, or descriptions, and should not be construed as being more preferred or advantageous than other embodiments or designs. The use of terms such as "exemplarily" and "preferredly" is intended to present the relevant concepts in a specific manner.

[0027] The technical solutions of this application can be applied to various communication systems, such as 5th Generation (5G) systems, New Radio Access Technology (NR), sidelink, and future communication systems, such as 6G systems.

[0028] The technical solutions of this application can be applied to various communication technologies, such as microwave communication, optical communication, and millimeter-wave communication. This application does not limit the specific technologies or equipment used.

[0029] The technical solutions of this application embodiment can be applied to various signals, including reference signals and / or channel signals. The reference signals include at least one of the following: SRS, demodulation reference signal (DMRS), phase-tracking reference signal (PT-RS), downlink channel state information reference signal (CSI-RS), preamble signal in the uplink physical random access channel (PRACH), and downlink synchronization signal. The channel signals include at least one of the following: data channel signal, control channel signal, and signals in the uplink physical random access channel (PRACH).

[0030] To facilitate understanding of the embodiments and parameters of this application, the above signals and related parameters are explained below.

[0031] SRS is an uplink physical signal sent by the terminal (UE) to the base station (gNB) in a 5G NR system. It is primarily used for acquiring uplink channel state information and optimizing network performance. SRS configuration information is sent from the gNB to the UE. The gNB transmits the SRS resource configuration information to the UE via Radio Resource Control (RRC) signaling. Based on this configuration information, the UE determines at least two time slots and transmits the SRS signal within those time slots.

[0032] DMRS is primarily used for wireless channel estimation to correctly demodulate the uplink and downlink physical channels. During communication, signals are distorted due to channel influences. DMRS allows the receiver to understand the channel characteristics and compensate for the received signal to correctly recover the original data.

[0033] PT-RS is primarily used as a reference signal for tracking and compensating for signal phase changes, especially in high-frequency communication scenarios such as the millimeter-wave band. The phase of a signal is easily affected by various factors, such as phase noise. By strategically distributing PT-RS in the time and frequency domain, the receiver can track phase changes in real time and correct the phase during demodulation, thereby improving demodulation accuracy.

[0034] CSI-RS is primarily used to acquire downlink channel state information, assisting base stations in resource allocation and scheduling. The base station transmits CSI-RS data, which the terminal receives and measures to obtain channel state information such as Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and Rank Indicator (RI). The terminal feeds this information back to the base station, which then uses the fed-back CSI data to optimize downlink transmission resource allocation, beamforming, and modulation / coding scheme selection to improve system performance and data transmission efficiency.

[0035] PRACH is the uplink channel used by a terminal to initiate a random access procedure. When a terminal is powered on, undergoing a handover operation, or needs to re-access the network, it sends an access request (such as a preamble) via PRACH. After receiving the request, the base station allocates resources to the terminal to complete the synchronization and connection establishment process.

[0036] The downlink synchronization signal consists of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). It is mainly used to achieve time and frequency synchronization between the terminal and the base station, and can also be used for cell identification.

[0037] The relevant parameters of the reference signal, such as configuration parameters, can be determined based on the signaling information. Specific configuration parameters include time-domain related parameters, frequency-domain related parameters, sequence and port parameters, power, beam parameters, time-domain behavior parameters, triggering parameters, and more.

[0038] Time-domain related parameters may include, but are not limited to, starting slot index, symbol index in time domain, starting position in time domain, position in time domain, number of symbols, number of slots, time domain offset, and other parameters.

[0039] Frequency domain related parameters may include physical resource blocks (PRBs), comb structures, and other parameters.

[0040] Sequence and port parameters can include cyclic shift (CS), number of SRS ports (nrofSRS-Ports), and group / sequence homing, such as group number u, group number v, etc.

[0041] Power can include transmission power (Power Control). Power-related parameters can include parameters such as spatial relation and transmit filter. For example, configuring the relationship between a signal and a first signal, where the transmission beam of the first signal is determined based on the transmission beam of the first signal when the two signals have the same transmission direction, and the transmission beam of the second signal is determined based on the reception beam of the first signal when the two signals have different transmission directions. The transmission directions include: a first direction where the first communication node transmits and the second communication node receives, and a second direction where the first communication node receives and the second communication node transmits.

[0042] The time-domain behavior parameters include: periodicity, non-periodicity, semi-persistent, periodic signals, or semi-persistent signals. The parameters also include period offset, frame index, and time slot index.

[0043] In related technologies, the signal in a reference signal unit can only be transmitted in one time slot. Since a single-time-slot reference signal only reflects the instantaneous channel state, it is difficult to characterize the dynamic changes in subsequent time slots. This is also unfavorable in at least one of the following scenarios: scenarios with limited transmitter power; scenarios with a low signal-to-noise ratio between the transmitter and receiver; and scenarios with high requirements for signal reliability and timeliness. These scenarios involve repeatedly transmitting signals in a single signal unit using multiple time-domain symbols or frequency hopping. Problems include inaccurate and untimely channel estimation, limited scheduling flexibility, and inability to adapt to changing channel conditions. Not only the reference signal, but also the channel signal itself, although it can be transmitted in multiple time slots, suffers from inflexible parameter configuration, leading to inflexible base station scheduling and an inability to effectively reduce power consumption at the base station and terminal sides, thus failing to guarantee signal reliability and timeliness.

[0044] Taking SRS as an example, according to the configuration information, the UE can only transmit signals in one designated time slot within an SRS resource. This makes it impossible for the base station to obtain timely and accurate information about rapid channel changes based on the SRS. Furthermore, it is unfavorable in at least one of the following scenarios: scenarios with limited transmitting power; scenarios with a low signal-to-noise ratio between the transmitting and receiving ends; and scenarios with high requirements for signal reliability and timeliness, where multiple time-domain symbols are repeatedly transmitted or frequency hopping is used. This results in inaccurate and untimely channel estimation, limited scheduling flexibility, and an inability to adapt to changing channel conditions. Not only reference signals, but although channel signals can be transmitted in multiple time slots, the parameter configuration is inflexible, and signals in multiple time slots are not correlated, leading to inflexible base station scheduling and an inability to effectively reduce power consumption on both the base station and terminal sides. This prevents the base station from performing joint channel estimation using signals from multiple time slots.

[0045] Based on this, embodiments of this application provide a wireless communication method, a wireless communication node, a wireless communication device, an electronic device, a computer-readable storage medium, and a computer program product. The wireless communication method is applied in a communication node, configuring a reference signal to occupy multiple time-domain symbols in multiple time slots according to signaling information.

[0046] The method described in this application can effectively improve the signal reception performance of the receiver, enabling it to obtain channel information more timely and accurately. It also enhances the reception performance of continuously repetitive or frequency-hopping signals in scenarios where the transmitter's power is limited or the signal-to-noise ratio (SNR) is low. Furthermore, it concentrates the active time of both communicating parties, allowing them to remain in a sleep state for longer periods, thus saving power consumption. Thirdly, the flexibility of parameter configuration effectively improves the flexibility of base station signal scheduling, increases the utilization of fragmented resources, enhances spectrum efficiency, reduces communication latency, and supports more services. Fourthly, by establishing the correlation between signals in multiple time slots, the transmitter's transmission parameters meet agreed-upon conditions across multiple time slots, allowing the receiver to perform joint reception based on signals from multiple time slots, thereby improving reception performance. Fifthly, transmitting signals under more time-domain symbols effectively improves signal reliability and timeliness, especially in scenarios with at least one of the following: limited transmitter power, low SNR between the transmitter and receiver, or high requirements for signal reliability and timeliness.

[0047] This application also provides various methods for configuring reference signal parameters, which can not only realize the transmission of signals across time slots in a signal unit, but also realize the transmission of signal unit sets, signal units, signal groups, etc. across time slots, and are suitable for a variety of different communication scenarios and needs.

[0048] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0049] Figure 1 This is a schematic diagram of a communication system provided in an embodiment of this application, as shown below. Figure 1 As shown in the embodiment, exemplarily, the communication system includes a base station 110 and multiple terminals, with the base station 110 communicating with a first terminal 121 and a second terminal 122 respectively.

[0050] It is understood that the number of devices and the communication relationships between devices in the communication system of this embodiment can be expanded and changed according to actual needs, and no specific limitations are made here.

[0051] The base station 110 in this application embodiment can be an evolved NodeB (eNB), a Transmission Reception Point (TRP), a Next Generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (Wi-Fi) system, etc. This application embodiment does not limit the specific technology or device form used in the network equipment.

[0052] The terminal in this application embodiment is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) device, an augmented reality (AR) device, a communication device in industrial control, a communication device in self-driving, a communication device in remote medical surgery, a communication device in a smart grid, a communication device in transportation safety, a communication device in a smart city, a communication device in a smart home, etc. This application embodiment does not limit the specific technology or form of the device.

[0053] The following example illustrates in detail the communication method of this application embodiment. Figure 1 Applications in the communication system shown:

[0054] For example, if the coverage of base station 110 includes a first terminal 121 and a second terminal 122, base station 110 sends a first signal to the first terminal 121 or receives a second signal sent by the second terminal 122.

[0055] In one example, base station 110 transmits a first signal to first terminal 121 over multiple time-domain symbols in at least two time slots.

[0056] In another example, the second terminal 122 transmits a second signal to the base station 110 over multiple time-domain symbols in at least two time slots.

[0057] For example, the first signal or the second signal may occupy two time slots, three time slots, four time slots, or multiple time slots.

[0058] In particular, in at least one of the following scenarios, such as when the signal-to-noise ratio of the base station and terminal channels is relatively low, when the reliability and timeliness requirements of the signal are relatively high, or when the transmission power of the transmitter is limited, the signal reception performance can be effectively improved by transmitting the signal on multiple time-domain symbols in at least two time slots for the same port.

[0059] In another example scenario, base station 110 sends a first signal unit to first terminal 121, or receives a second signal unit sent by second terminal 122, wherein the signal in one of the signal units includes the signal on each port of at least one reference signal port corresponding to the signal unit.

[0060] In another example scenario, base station 110 sends a first set of signal units to a first terminal 121, or receives a second set of signal units sent by a second terminal 122, wherein the signal in one of the signal units includes the signal on each port of at least one reference signal port corresponding to the signal unit.

[0061] The signals in the embodiments of this application may include reference signals, such as a sounding reference signal (SRS); a demodulation reference signal (DMRS); a phase tracking reference signal (PT-RS); a downlink channel state information reference signal (CSI-RS); a downlink synchronization signal; and a preamble signal in the uplink physical random access channel. They may also include channel signals, such as the uplink physical random access channel (PRACH) signal; control channel signals; and data channel signals, which are not limited herein. The following description uses reference signals as an example.

[0062] In another embodiment, the signal in this application can be a periodic signal or a semi-continuous signal. When the signal can be a periodic signal or a semi-continuous signal, at least two time slots are at least two time slots corresponding to the signal unit within one period.

[0063] The signal in the embodiments of this application can also be an aperiodic signal. When the signal can be an aperiodic signal, at least two time slots are the at least two time slots corresponding to one aperiodic transmission of the signal unit.

[0064] Figure 2 This is a wireless communication method provided in one embodiment of this application. For example... Figure 2 As shown, the first communication node 210 sends a signal from a signal element to the second communication node 220, such as sending a reference signal or a message carrying a reference signal. The wireless communication method applied to the first communication node 210 includes step S100.

[0065] S100: Transmit a signal in a signal unit on multiple time domain symbols in at least two time slots, for example, transmit a reference signal in a reference signal unit on multiple time domain symbols in at least two time slots.

[0066] In one example, a reference signal element is a reference signal resource or a group of reference signal resources. A group of reference signal resources may include one or more reference signal resources, and a reference signal resource may include one or more reference signal ports.

[0067] In one example, the signals in a signal unit include the signals on each of at least one reference signal port corresponding to the signal unit. The signals include at least one of the following: a reference signal and a channel signal. The reference signal carries no information, or only a small amount of information, primarily to allow the receiver to obtain the channel characteristics based on the reference signal. The channel signal carries information sent from the transmitter to the receiver, and is generally demodulated using a demodulation reference signal.

[0068] In one example, the signal can be either an uplink or downlink signal. The communication node can be a terminal device or a base station device. For example, if the signal is an uplink reference signal, the first communication node 210 can be a terminal device, and the second communication node 220 can be a base station device or other network device. If the signal is a downlink reference signal, the first communication node 210 can be a base station device or other network device, and the second communication node 220 can be a terminal device. Alternatively, in a Sidelink scenario, the first communication node 210 and the second communication node 220 can be two different terminal devices.

[0069] The reference signal transmitted in the embodiments of this application can be in at least two consecutive time slots or in at least two non-consecutive time slots. That is, at least two time slots can be two consecutive time slots, three consecutive time slots, or multiple consecutive time slots, or they can be two non-consecutive time slots or multiple non-consecutive time slots.

[0070] The following section uses SRS as an example to further illustrate the embodiments of this application. It should be emphasized that the solutions of the embodiments of this application are applicable to various signals and are not limited to SRS. Those skilled in the art will understand that they can be applied to different signals, or that simple modifications, substitutions, or conversions based on this solution are also within the scope of this application. For example, when using the solution of the embodiments of this application for other uplink signals, it is only necessary to replace the example SRS with the name of another uplink signal. Similarly, when using the solution of the embodiments of this application for other downlink signals, it is only necessary to replace the example SRS with the name of another downlink signal, and replace the terminal with a base station, and the base station with a terminal, or replace the transmitting end with a receiving end, and the receiving end with a transmitting end.

[0071] Figure 3 and Figure 4 This is a schematic diagram of a time slot provided in an embodiment of this application. For example... Figure 3 As shown in Figure 4, in this embodiment, at least two time slots can be two consecutive time slots, slot n and slot n+1. At least two time slots can also be three consecutive time slots, slot n, slot n+1 and slot n+2, or multiple consecutive time slots, slot n, slot n+1...slot n+m.

[0072] Figure 5 This is a schematic diagram of a time slot provided in an embodiment of this application. For example... Figure 5 As shown, in this embodiment, at least two time slots can be two non-contiguous time slots, slot n and slot n+3. At least two time slots can also be multiple non-contiguous time slots.

[0073] Figures 3 to 5 In the diagram, each rectangle D, F, U represents one or more time-domain symbols.

[0074] like Figure 3 As shown, multiple time-domain symbols occupied by an SRS resource can be located in two consecutive time slots, slot n and slot n+1, and are located in consecutive time-domain symbols. That is, the multiple time-domain symbols are F and U located in slot n, and F located in slot n+1. In this embodiment, the number of consecutive time-domain symbols can be an integer multiple of a preset value.

[0075] like Figure 4As shown, multiple time-domain symbols occupied by an SRS resource can be located in two consecutive time slots, slot n and slot n+1, and are not contiguous time-domain symbols. That is, the multiple time-domain symbols are F and U located in slot n, and U located in slot n+1.

[0076] like Figure 5 As shown, multiple time-domain symbols occupied by an SRS resource can be located in two discontinuous time slots, slot n and slot n+3, and these discontinuous time-domain symbols are F and U located in slot n, and U located in slot n+3.

[0077] In one embodiment, the reference signal can be transmitted in a frequency-hopping manner or in a non-frequency-hopping manner. For example, the signal in a signal unit can be transmitted in a frequency-hopping or non-frequency-hopping manner on consecutive time-domain symbols in a plurality of time-domain symbols, or the signal in a signal unit can be transmitted in a frequency-hopping manner on discontinuous time-domain symbols in a plurality of time-domain symbols.

[0078] In one embodiment, candidate values ​​for frequency hopping intervals on consecutive time-domain symbols constitute a first frequency hopping interval candidate set, and candidate values ​​for frequency hopping intervals on non-consecutive time-domain symbols constitute a second frequency hopping interval candidate set. The first and second frequency hopping interval candidate sets are different sets. For example, the first frequency hopping interval candidate set includes a first value, and the second frequency hopping interval candidate set includes a second value, wherein the first value is less than the second value, and / or the maximum value in the first frequency hopping interval candidate set is less than the maximum value in the second frequency hopping interval candidate set.

[0079] Figure 6 This is a wireless communication method provided in one embodiment of this application. For example... Figure 6 As shown, the first communication node 210 sends a signal from a signal unit to the second communication node 220. It should be noted that the signal in a signal unit represents the signal on each of the at least one reference signal port corresponding to the signal unit. For example, if the signal is a reference signal and the signal unit is a reference signal resource, a reference signal resource includes one or more reference signal ports, and the signal in a signal unit includes the reference signal on one or more reference signal ports included in the reference signal resource. The reference signal is transmitted on a time-frequency resource determined according to the parameters configured in the reference signal unit. The wireless communication method applied to the first communication node 210 includes steps S10 and S100.

[0080] S10: Receive signaling information.

[0081] S100: Transmit a signal in a signal unit on multiple time-domain symbols in at least two time slots.

[0082] In one example, the signaling information is first signaling information. The first signaling information includes at least one of the following parameters: determining the starting time slot index in at least two time slots corresponding to the signal unit, the number of time slots included in the at least two time slots, the starting time domain symbol position of multiple time domain symbols in the starting time slot of the at least two time slots, the number of time domain symbols included in the multiple time domain symbols, and the starting time domain symbol position of multiple time domain symbols in the time domain symbol set included in the at least two time slots.

[0083] In one example, the signaling information is second signaling information. The second signaling information includes parameters for determining at least one of the following: the starting time slot index in at least two time slots, the number of time slots included in the at least two time slots, and the time-domain symbol position of the signal in each of the at least two time slots. In some cases, the relative indices of the time-domain symbols occupied by multiple time-domain symbols in each of the at least two time slots may be different. For example, time-domain symbols 2 and 3 may be occupied in time slot 1, and time-domain symbols 12 and 13 may be occupied in time slot 2. When the relative indices are different, independent signaling notification is required. Alternatively, only the time-domain symbol position in one reference time slot may be notified, followed by the offset relative to the reference time slot in the other time slots. If the relative indices of the time-domain symbols occupied in different time slots are different, the number of time-domain symbols occupied in different time slots may be required to meet a convention or preset condition. For example, the number may be an integer multiple of a convention value, such as R in the example. The reference signal changes its PRB set position once every R time-domain symbols it occupies, while the frequency domain position occupied by the reference signal remains unchanged across the R time-domain symbols. In other cases, multiple time-domain symbols may have the same relative index in each of at least two time slots.

[0084] In one example, the signaling information is third signaling information. The third signaling information includes at least one parameter for determining the index of each of the at least two time slots, the period offset corresponding to each of the at least two time slots, the number of time slots included in the at least two time slots, and the time-domain symbol position of the signal in each of the at least two time slots. In some cases, the relative indices of multiple time-domain symbols in each of the at least two time slots may be different. For example, time-domain symbols 2 and 3 may be occupied in time slot 1, and time-domain symbols 12 and 13 may be occupied in time slot 2. When the relative indices are different, independent signaling notification is required. Alternatively, only the time-domain symbol position in one reference time slot can be notified, and then the offset relative to the reference time slot in the other time slots can be notified. If the relative indices of the time-domain symbols occupied in different time slots are different, it can be further required that the number of time-domain symbols occupied in different time slots meet a pre-defined or agreed-upon condition. For example, if the number is an integer multiple of a predetermined value, such as R, the reference signal changes its PRB set position once every R time-domain symbols it occupies, while its frequency domain position remains unchanged across the R time-domain symbols. In other cases, multiple time-domain symbols may have the same relative index in each of at least two time slots.

[0085] In one example, the signaling information is the fourth signaling information. The fourth signaling information includes first configuration parameters for the reference signal. These first configuration parameters are used to determine the parameters of the reference signal in each of at least two time slots. The configuration granularity of the first configuration parameters is a reference signal element or the set of signal elements to which the signal element belongs.

[0086] In one example, the signaling information is the fifth signaling information. The fifth signaling information includes second configuration parameters for a reference signal. The second configuration parameters include at least two sets of parameter values. Each set of values ​​in the at least two sets of parameter values ​​is used in at least one of at least two time slots, and each set of values ​​is used in a different time slot. The configuration granularity of the second configuration parameters is one time slot, one time slot group, or one time slot group, where two time slots include multiple time slots, or multiple time slot groups.

[0087] In one example, the first configuration parameter includes some or all of the parameters used to determine the reference signal in the reference signal unit.

[0088] In another example, the first configuration parameters include at least one of the following: determining the Physical Resource Block (PRB), the number of reference signal ports corresponding to the signal unit, the signal period, the transmit beam, the transmit power, sequence parameters, power parameters, transmit filter parameters, frequency hopping parameters, the start time slot of at least two time slots, the reference time slot, one of the at least two time slots, the number of time slots included in the at least two time slots, the number of time domain symbols included in the multiple time domain symbols, phase, timing advance, effective time slot, at least two time slots, and the offset between each of the at least two time slots and the reference time slot. The sequence parameters may include at least one of the following: sequence group number, sequence number, and cyclic shift parameters.

[0089] In one example, the second configuration parameter includes parameters for determining at least one of the following: a time-domain symbol index parameter, a cyclic shift parameter, a comb structure parameter, a power parameter, an effective time slot, and an offset between a reference time slot. The reference time slot may include at least one of the following: the time slot containing the downlink control information, one of at least two time slots, and the starting time slot of at least two time slots. The downlink control information may include information about a trigger signal unit.

[0090] In one example, the signaling information is the sixth signaling information. The sixth signaling information includes a third configuration parameter for determining the set of signal elements to which the signal element belongs, wherein the configuration granularity or determination granularity of the third configuration parameter is the set of signal elements.

[0091] The third configuration parameters include at least one of the following: the number of ports included in each signal unit, power parameters, time characteristic parameters, purpose parameters of the signal unit set, transmit filter parameters, the position of the reference time slot in the multiple time slots corresponding to all signal units in the signal unit set, and period. The time characteristic parameters include at least one of periodic, aperiodic, and semi-continuous.

[0092] In one example, the signaling information is the seventh signaling information. The seventh signaling information includes a fourth configuration parameter for determining each signal element in the set of signal elements to which the signal element belongs, wherein the configuration granularity or determination granularity of the fourth configuration parameter is the signal element.

[0093] The fourth configuration parameter includes at least one of the following parameters for determining the offset of every other time slot relative to a reference time slot in at least two time slots where the signal resides: one of the at least two time slots, the starting time slot of the at least two time slots, a period offset, and an effective time slot. The reference time slot includes the time slot where the downlink control information is located, and the downlink control information includes information about the trigger signal unit.

[0094] In one example, if at least two time slots are at least two valid time slots, then at least two valid time slots satisfy at least one of the following characteristics:

[0095] The relevant parameters for at least two valid time slots are determined based on the received eighth signaling information and / or agreed rules;

[0096] There is a one-to-one correspondence between at least two time slots and at least two valid time slots, wherein at least two valid time slots are different time slots;

[0097] Each of the at least two valid time slots satisfies at least one of the following characteristics: the transmission direction of the time domain symbol belonging to multiple time domain symbols included in the valid time slot is the direction of the signal sent by the first communication node; the interval between the valid time slot and the reference time slot is greater than or equal to a predetermined value; the time domain symbol belonging to the valid time slot included in the valid time slot is not occupied by the time domain symbol belonging to multiple time domain symbols in other time slots of the at least two time slots; wherein the time domain symbol belonging to the valid time slot belongs to multiple time domain symbols and is the time domain symbol index corresponding to one of the at least two time slots; and one of the time slots has a corresponding relationship with the valid time slot.

[0098] At least two valid time slots are associated with parameters used to determine the valid time slots;

[0099] At least two time slots are used to search for valid time slots in a pre-agreed order;

[0100] At least two valid time slots correspond to actual time spans that are less than or equal to a first predetermined value;

[0101] The relative time relationship between at least two valid time slots is determined based on the relative time relationship between the corresponding at least two time slots;

[0102] The time interval between different valid time slots in at least two valid time slots is determined based on the time interval between different time slots in at least two time slots.

[0103] In another example, when a signal element belongs to a set of signal elements, all signal elements in the set correspond to N time slots, where N is a positive integer greater than 1, and the N time slots include at least two time slots. Determining one or more valid time slots corresponding to each signal element in the set includes at least one of the following:

[0104] A set of signal units includes multiple signal units that search for valid time slots in a predetermined order;

[0105] The effective time slot corresponding to a signal unit satisfies the following characteristic: the time domain symbol of the corresponding signal unit in the effective time slot is not occupied by other signal units in the signal unit set whose effective time slots have been determined.

[0106] Determine the M effective time slots corresponding to the signal unit set, where M is less than or equal to N.

[0107] In one example, the M valid time slots satisfy at least one of the following characteristics:

[0108] M valid time slots are within a time range that is less than the second predetermined value;

[0109] M valid time slots are within a time range that is less than the second predetermined value;

[0110] The relevant parameters for the M valid time slots are determined based on the received ninth signaling information and / or agreed rules;

[0111] The M effective time slots are different effective time slots;

[0112] When M equals N, there is a one-to-one correspondence between the N time slots and the M effective time slots;

[0113] When M equals N, all signals in the signal unit set are transmitted in the M effective time slots;

[0114] Each of the M valid time slots is associated with a parameter used to determine the valid time slot;

[0115] The valid time slots among the N time slots are searched sequentially according to a pre-defined order;

[0116] The relative time relationship of M effective time slots is determined based on the relative time relationship of N two time slots;

[0117] The time interval between different effective time slots in M ​​effective time slots is determined based on the time interval between different time slots in at least N time slots;

[0118] When M is less than N, some of the N time slots do not have corresponding valid time slots, and signals belonging to the signal unit set are not transmitted on some of the time slots. The partial time slots include all the time slots corresponding to one or more signal units in the signal unit set.

[0119] When M is less than N, some of the N time slots do not have corresponding valid time slots, and signals belonging to the signal unit set are not transmitted on some of the time slots. The partial time slots include some of the time slots in at least two time slots corresponding to the signal unit.

[0120] When M is less than N, the M effective time slots include at least one or more first effective time slots, wherein each first effective time slot corresponds to more than one of the N time slots, and signals belonging to the signal unit set in more than one time slot are transmitted in the first effective time slot.

[0121] In one example, the signaling information is the eighth signaling information. Based on the eighth signaling information, the relevant parameters of the effective time slots corresponding to at least two time slots are determined. Alternatively, the relevant parameters of the effective time slots corresponding to at least two time slots can be determined according to agreed-upon rules or preset rules. The signal unit corresponds to at least two valid time slots, wherein at least two time slots and at least two valid time slots correspond one-to-one, and the at least two valid time slots are different time slots; the at least two valid time slots corresponding to the signal unit satisfy the following characteristics: the transmission direction of the time domain symbol belonging to the valid time slot included in the valid time slot is the direction of the signal sent by the first communication node; the interval between the valid time slot and the reference time slot is greater than or equal to a predetermined value; the time domain symbol belonging to the valid time slot included in the valid time slot is not occupied by time domain symbols belonging to multiple time domain symbols in other time slots of the at least two time slots, wherein the time domain symbol belonging to the valid time slot is a signal belonging to multiple time domain symbols in one time slot of the corresponding valid time slot of the at least two time slots; the parameters of the valid time slots corresponding to the at least two time slots are different; the at least two valid time slots corresponding to the signal unit search for valid time slots in sequence according to an agreed order; the actual time span corresponding to the at least two valid time slots of the signal unit is less than or equal to a first predetermined value.

[0122] In another example, when a signal unit belongs to a set of signal units, the relevant parameters of the effective time slots corresponding to at least two time slots are determined according to the received eighth signaling information and / or agreed rules. This can be determined based on at least one of the following: multiple signal units included in a set of signal units sequentially search for effective time slots in a predetermined order; the effective time slots corresponding to a signal unit satisfy the following characteristics: the time domain symbol of the corresponding signal unit in the effective time slot is not occupied by other signal units preceding the signal unit; more than one effective time slot is determined corresponding to the set of signal units, and signals from all signal units in the set are transmitted in the more than one effective time slot, wherein the more than one effective time slot includes at least two effective time slots, and the at least two effective time slots correspond one-to-one with the at least two time slots, with different signal units occupying different or the same effective time slots; more than one effective time slot is determined corresponding to the set of signal units, wherein the actual time interval corresponding to the more than one effective time slot is less than a second predetermined value; the effective time slots corresponding to each signal unit in the set of signal units are determined respectively, and at least two effective time slots corresponding to each signal unit in the set of signal units are determined based on the index of the effective time slots.

[0123] In one example, a signal element belongs to a set of signal elements. Transmitting a signal in a signal element on multiple time-domain symbols in at least two time slots includes at least one of the following methods: transmitting all signal elements in the set of signal elements on multiple time-domain symbols in at least two valid time slots; transmitting all signals in at least one signal element in the set of signal elements on multiple time-domain symbols in at least two valid time slots; or transmitting at least one signal in at least one signal element in the set of signal elements on multiple time-domain symbols in at least two valid time slots.

[0124] Based on the received eighth signaling information and / or agreed rules, the relevant parameters of the effective time slots corresponding to at least two time slots are determined, which can be determined according to at least one of the following: multiple signal units included in a signal unit set search for effective time slots in a predetermined order; the effective time slots corresponding to the signal units satisfy the following characteristics: the time domain symbol of the corresponding signal unit in the effective time slot is not occupied by other signal units before the signal unit; more than one effective time slot is determined corresponding to the signal unit set, and the signals of all signal units in the signal unit set are transmitted in the more than one effective time slot, wherein the more than one effective time slot includes at least two effective time slots, the at least two effective time slots and the at least two time slots correspond one-to-one, and different signal units occupy different or the same effective time slots; more than one effective time slot is determined corresponding to the signal unit set, wherein the actual time interval corresponding to the more than one effective time slot is less than a second predetermined value; the effective time slots corresponding to each signal unit in the signal unit set are determined respectively, and at least two effective time slots corresponding to each signal unit in the signal unit set are determined according to the index of the effective time slots.

[0125] In one example, a signal element belongs to a set of signal elements. Transmitting a signal in a signal element on multiple time-domain symbols in at least two time slots includes at least one of the following methods: transmitting all signal elements in the set of signal elements on multiple time-domain symbols in at least two valid time slots; transmitting all signals in at least one signal element in the set of signal elements on multiple time-domain symbols in at least two valid time slots; or transmitting at least one signal in at least one signal element in the set of signal elements on multiple time-domain symbols in at least two valid time slots.

[0126] In another example, the parameters of the signal change over time. Exemplarily, multiple time-domain symbols correspond to the same transition formula, wherein the time slot index in the transition formula is the index of the starting time slot among at least two time slots, and / or the index of the time-domain symbol in the transition formula is the index of the time-domain symbol among multiple time-domain symbols.

[0127] In one example, the parameters of the signal can be at least one of the following: Physical Resource Block (PRB), Comb Structure (COM), Sequence Group Number (u), Sequence Group Number (v), and Cyclic Shift (CS).

[0128] In another example, the number of time-domain symbols included in the multiple time-domain symbols satisfies one of the following conditions: the number of time-domain symbols is less than or equal to a predetermined threshold; the number of time-domain symbols included in each of at least two time slots is the same or different; the number of multiple time-domain symbols is an integer multiple of a first value; or the number of time-domain symbols in each of at least two time slots is an integer multiple of the first value. The first value includes R, where the signal changes its occupied PRB set position once every R time-domain symbols it occupies, the frequency domain position occupied by the signal remains unchanged in the R time-domain symbols, and at least one of the following: the number of time-division multiplexed signal port groups included in the signal unit.

[0129] Figure 7 This is a wireless communication method provided in one embodiment of this application. For example... Figure 7 As shown, the second communication node 220 receives a signal from a signal unit sent by the first communication node 210. The wireless communication method applied to the second communication node 220 includes step S200.

[0130] S200: Receive a signal in a signal element across multiple time-domain symbols in at least two time slots, for example, receive a signal in a signal element across multiple time-domain symbols in at least two time slots. The signal in a signal element represents the signal on each of at least one reference signal port corresponding to the signal element. For example, if the signal is a reference signal and the signal element is a reference signal resource, a reference signal resource includes one or more reference signal ports, and the signal in a signal element includes the reference signal on one or more reference signal ports included in the reference signal resource. The reference signal is received on a time-frequency resource determined according to the parameters configured for the reference signal element.

[0131] The signals received in the embodiments of this application can be a series of consecutive time-domain symbols located in at least two consecutive time slots, or they can be located in two consecutive time slots and include discontinuous time-domain symbols among the multiple time-domain symbols, or they can be located in at least two discontinuous time slots and include discontinuous time-domain symbols among the multiple time-domain symbols.

[0132] It should be noted that the aforementioned examples applicable to the first communication node 210 also apply to the second communication node 220 in this embodiment, and will not be repeated here. The only difference is that the step of determining parameters based on received signaling information is changed from "sending" to "receiving," and then to "determining parameters" and "sending signaling information based on the determined parameters," whereby the signaling information includes information related to the parameters. The signaling information includes one or more of the first to ninth signaling information mentioned above, or other signaling information as described herein.

[0133] In this document, the first to ninth signaling information can be the same or different signaling information.

[0135] The transmitting module 310 is used to transmit a signal in a signal unit on multiple time domain symbols in at least two time slots.

[0136] The receiving module 320 is used to receive signaling information.

[0137] Figure 9 This application provides a wireless communication device 400 according to one embodiment. Figure 9 As shown, the wireless communication device includes a receiving module 4100.

[0138] The receiving module 410 is used to receive a signal in a signal unit on multiple time domain symbols in at least two time slots.

[0139] To enable those skilled in the art to better understand the technical solution of the present invention, the following description uses SRS as an example, combined with specific examples.

[0140] To enable a terminal to transmit SRS on multiple time-domain symbols located in multiple slots, one or more of the following methods can be used.

[0141] Example 1: Configure an SRS resource to occupy multiple time-domain symbols in multiple slots.

[0142] There are multiple slots, which are more than one slot. For the characteristics of multiple slots, any one of the following schemes A.1 to A.3 can be adopted.

[0143] Option A.1: Restrict these multiple time-domain symbols to be consecutive time-domain symbols, such as... Figure 3As shown, this avoids the terminal's antenna going from off to on, thus reducing the random phase rotation introduced by the switching operation and preventing inaccurate channel measurements. Therefore, the base station configures multiple slots, including the starting slot index, the starting time-domain symbol position, the time-domain symbol index in the starting slot, and the number of time-domain symbols. For example, the starting slot index... According to the period T SRS and periodic bias T offset Obtain, and Satisfy the following formula:

[0144]

[0145] in n is the number of slots included in a frame. f Indicates the index of the frame. This is the index of the starting slot. For the starting time-domain symbol and the number of time-domain symbols, the position of the starting time-domain symbol, its index, and its number within the starting slot can be directly communicated. Alternatively, to save signaling overhead, the start and length indicator SLIV method can be used, where S is the starting time-domain symbol index, L is the number of time-domain symbols, and L is the number of time-domain symbols located in the aforementioned multiple slots. Of course, to ensure consistent signaling for symbols located in a single slot and those in multiple slots, L time-domain symbols can also be located in a single slot. The SLIV is obtained according to the following algorithm. Furthermore, the SLIV method can also be used for multiple consecutive slots.

[0146] if Then SLIV = L max ·(L-1)+S

[0147] Otherwise SLIV = L max ·(L max -L+1)+(L max -1-S)

[0148] Among them 1 <L≤L max -S,L max To maximize the number of time-domain symbols, in one implementation L max Also according to Get, for example S represents the number of time-domain symbols included in a slot. In this case, S is the index of the starting time-domain symbol in the set of time-domain symbols included in all slots across multiple slots. Alternatively, you can simply provide the number of slots and then obtain the position of the starting time-domain symbol using the SLIV method described above.

[0149] Option A.2: These time-domain symbols can be consecutive or non-consecutive, but located in consecutive slots. For example, configure the starting slot, the number of slots, and the position of the time-domain symbol within each slot. That is, configure the starting slot and the number of slots in the SRS within a period. The starting slot index... Satisfying formula (1), such as Figure 4 As shown. The configuration specifies the time-domain symbol index and number of time-domain symbols occupied by the SRS in each slot, or only one set of time-domain symbol index and number of time-domain symbols can be configured, where the SRS occupies the same time-domain symbol index and number of time-domain symbols in each slot. Furthermore, the SLIV method can be used for multiple consecutive slots.

[0150] Option A.3: These multiple time-domain symbols can be located in multiple non-contiguous slots. In this case, configure the slot index corresponding to the multiple slots occupied by the SRS in a period. and bias T offset,i ,like Figure 5 As shown, it satisfies the following formula

[0151]

[0152] N slot,SRS It represents the number of slots occupied by the SRS. T represents the index of the i-th time slot. offset,i This represents the period offset corresponding to the i-th time slot. It also configures the time-domain symbol index and the number of time-domain symbols occupied by the SRS in each slot, or configures only one set of time-domain symbol index and number of time-domain symbols, where the time-domain symbol index and number of time-domain symbols occupied by the SRS are the same in each slot. Alternatively, it can notify a reference slot of its corresponding slot index. and bias T offset,0 It also notifies the slot offsets of the other slots occupied by the SRS relative to the aforementioned reference slot. The period T corresponding to the SRS in multiple slots... SRS Same. A reference slot can be the starting slot for multiple slots.

[0153] In schemes A.1 to A.3, the number of time-domain symbols of an SRS resource in its occupied slots can be further restricted to meet the agreed conditions, wherein the agreed conditions include at least one of the following: the number of time-domain symbols is less than or equal to a predetermined threshold (for example, considering scheduling flexibility, channel coherence time length, the limited time for terminals to maintain certain parameters being the same or continuous, and the limited time for base stations to jointly receive signals at multiple times, so the number of time-domain symbols cannot be greater than the predetermined threshold, such as 24, 36, 18, etc.); the number of time-domain symbols of the signals included in each of at least two time slots is the same or different; the number of time-domain symbols is an integer multiple of a first value; the number of time-domain symbols in each of at least two time slots is an integer multiple of a first value; wherein the first value includes at least one of the following: R, an SRS resource changes the position of its occupied PRB set once every R time-domain symbols, and the frequency domain position occupied by an SRS resource remains unchanged in the R time-domain symbols; the number of time-division multiplexed signal port groups included in the signal unit.

[0154] Scheme A.1 is suitable for both non-frequency-hopping and frequency-hopping transmission of SRS across multiple time-domain symbols. If the terminal cannot maintain phase continuity or consistency across discontinuous time-domain symbols, then Schemes A.2 to A.3 are only suitable for frequency-hopping transmission of SRS across multiple time-domain symbols. Furthermore, the discontinuous time-domain symbols can be further limited to SRS located at different frequency domain positions, excluding SRS at the same frequency domain position, or at least when the slot changes, the frequency domain position also changes. Especially after a frequency domain position change, the terminal's transmission may introduce random phase rotation, such as when the frequency domain position interval is relatively large. Figure 4 In slot n+1, the frequency domain position occupied by the SRS changes at the beginning of the time domain symbol. For example... Figure 5 In the first time-domain symbol of slot n+3, the frequency domain position occupied by the SRS changes. If the terminal can maintain phase continuity or consistency across discontinuous time-domain symbols, then schemes A.2 to A.3 are also suitable for non-frequency-hopping transmission of the SRS across these multiple time-domain symbols. Alternatively, in schemes A.2 to A.3, if there are downlink time-domain symbols between discontinuous time-domain symbols, causing uplink-to-downlink switching and resulting in the inability to guarantee the phase continuity or consistency of the terminal, then the terminal must not receive downlink signals on discontinuous time-domain symbols.

[0155] The aforementioned period refers to the period corresponding to one SRS resource. For a non-periodic SRS resource, one trigger transmission corresponds to only one period. That is, when applying schemes A.1 to A.3 to a non-periodic SRS, the configuration of multiple slots in schemes A.1 to A.3 corresponds to multiple slots for one transmission of the non-periodic SRS resource. The above slot notification method does not require a period or period offset, but rather notifies the DCI that triggers the non-periodic SRS and the offset of the slot occupied by the SRS. For example, schemes A.1 and A.2 notify the offset corresponding to the starting slot occupied by the SRS and the number of slots, while scheme A.3 notifies the offset of each slot, or the offset of a reference slot, and the offset of other reference slots with the same slots.

[0156] For an SRS located in multiple slots, the configuration of the SRS parameters can adopt one or more of the following B.1 to B.3, wherein the SRS parameters include at least one of the following: time-domain symbol index, wherein the time-domain symbol index is the index of multiple time-domain symbols included in a slot by the time-domain symbol occupied by the SRS, cyclic shift parameter, occupied comb parameter, occupied PRB related parameters, sequence parameter, power parameter, and transmit filter related parameters.

[0157] Option B.1: Each SRS resource is configured with a set of parameters. This set of parameters is adapted to multiple slots corresponding to this SRS resource within a single period. For example, the parameters may be the same across multiple slots, or the parameters may change with time-domain symbols or frequency-domain transitions. The parameters for the initial time-domain symbol are obtained based on this set of parameters, and other parameters change according to agreed-upon rules. In other words, the parameter configuration is at the SRS resource level. This reduces signaling overhead but decreases the flexibility of SRS scheduling and allocation at the base station.

[0158] Option B.2. An SRS resource is configured with multiple parameters. Each set of parameters is suitable for one slot (or a group of slots, where one or more slots are included) from multiple slots. The difference from Option B.1 is that parameters are configured at the slot level. This allows for different parameters for a single SRS resource in different slots, enabling the base station to manage SRS resources based on slots. For example, in... Figure 3In this configuration, SRS resource 1 includes 4 SRS ports. In slot n, the base station schedules a total of 8 SRS ports in the time domain symbol occupied by SRS. Four of these SRS ports are from SRS resource 1 sent by UE1, and the other four are from SRS resource 3 sent by UE2. In slot n+1, the base station allocates only 4 SRS ports in the time domain symbol occupied by SRS; these 4 SRS ports are from SRS resource 1 of UE1. Thus, the SRS parameter configurations corresponding to SRS resource 1 can differ between the two slots. For example, in slot n+1, the cyclic shift interval occupied by the 4 SRS ports in SRS resource 1 can be larger than that in slot n. Furthermore, if the base station has already allocated other periodic or aperiodic SRSs in these two slots, and if a new SRS resource 1 needs to be allocated in slot n and slot n+1, but the parameters (i.e., the remaining parameters) of the unallocated SRSs in the two slots are different, then if scheme B.1 is used, this SRS resource 1 cannot be allocated, but if scheme B.2 is used, SRS resource 1 can be allocated.

[0159] Option B.3: Some parameters of an SRS resource are resource-level (i.e., there is only one set), while others are slot-level (i.e., configured independently for each slot). For example, at least one of the following parameters is required: COM parameters, cyclic shift (CS) parameters are configured at the slot level, and sequence parameters. At least one of the following parameters is configured at the resource level: frequency domain PRB-related parameters, occupied slots, number of SRS ports included, transmit power, transmit beam-related parameters, and sequence parameters. The frequency domain PRB-related parameters include at least one of the following: n shift (The initial deviation of the root relative to the system bandwidth in a multi-level structure), n RRC (Used to determine the initial SRS position and the deviation of the root start position in a multilevel structure), C SRS B SRS ,b hop These correspond to the selection of multi-level structures, the level of the largest multi-level structure (i.e., the level corresponding to the frequency band transmitted at each moment), and the level corresponding to the bandwidth range of the jump. Parameters for determining the frequency domain location (i.e., the offset used to determine the frequency hopping sequence for each terminal). Sequence parameters can be at the resource level or the slot level, and include at least one of the following: sequence group number u, sequence number v. Each has its advantages and disadvantages; the former can reduce signaling overhead, and is generally the same for a single cell. The latter is more flexible and can multiplex SRS for UEs in different slots and at different base stations. In one implementation, this SRS resource includes the same SRS ports in various slots across multiple slots; for example, this SRS resource includes 4 SRS ports, which are transmitted on each time-domain symbol occupied by this SRS. In another implementation, this SRS resource includes different SRS ports in various slots across multiple slots; for example, this SRS resource includes 8 SRS ports, with 4 of the 8 SRS ports included in slot n, and the remaining 4 of the 8 SRS ports included in the second slot.

[0160] When the parameter is configured or defined at the slot level, the slot index... Replace with This represents the i-th slot in a set of multiple slots. Replace with This represents the number of time-domain symbols occupied by the SRS in the i-th slot. In the case where different slots occupy the same number of time-domain symbols, ... The subscript 'i' can be omitted. Replace 'l' with 'l'. i i is the index of the time-domain symbol occupied by the SRS in the i-th slot among the multiple time-domain symbols in this slot.

[0161] For various time-varying parameters, such as existing time-varying parameters including PRB, com, u, v, and when an SRS resource occupies multiple time-domain symbols in a single period, enhancement is required. One or more of the following schemes C.1 to C.2 can be adopted:

[0162] Option C.1: The existing formula based on one SRS resource occupying one slot remains unchanged, but the slot index in the formula is declared. It is the starting slot index among a series of consecutive slots. It represents the number of consecutive time-domain symbols occupied by the SRS across multiple slots. l′ represents the number of consecutive time-domain symbols occupied by the SRS. Relative indexes within time-domain symbols. This approach is suitable for scenarios with multiple slots, such as A.1, where the jump parameters are configured at the resource level.

[0163] Specifically, when the transition parameter is PRB, the existing method for calculating the number of time-domain transitions, n... SRS The formula is as follows:

[0164]

[0165] Formula (2) is for periodic and semi-continuous SRS, and formula (3) is for non-periodic SRS.

[0166] For the jump parameter CS (cyclic shift), the formula is as follows:

[0167]

[0168] Where c(z) is the z-th value of the random sequence c. l0 is the index of the initial time-domain symbol occupied by the SRS in the initial slot, l0∈{0,1...13}. It is the number of elements included in the CS subset of the SRS transition. It is a subset of CS that jumps.

[0169] For the case where the jump parameter is comb, the formula is as follows:

[0170]

[0171] Or l″ = l′, It is a subset of the comb that jumps. yes The number of elements included It is a set The z-th element in.

[0172] For the case where the jump parameter is the sequence group number u, the formula is as follows:

[0173]

[0174] For the case where the jump parameter is the sequence number v, the formula is as follows:

[0175]

[0176] Scheme C.2, where each slot jumps independently, is suitable for any of Schemes A.1 to A.3, and is suitable for parameter configurations at the slot level. Furthermore, the jump parameter configuration is at the slot level, and the corresponding slot indexes in formulas (2) to (6) are... Replace with This represents the i-th slot in a set of multiple slots. Replace with This represents the number of time-domain symbols occupied by the SRS in the i-th slot. In the case where different slots occupy the same number of time-domain symbols, ... The subscript 'i' can be omitted. Replace 'l' with 'l'. i It is the index of the time domain symbol occupied by the SRS in the i-th slot among the multiple time domain symbols in this slot.

[0177] Scheme C.3: In the hopping parameters PRB, com, u, v, cs, some parameters are from Scheme C.1, and some are from Scheme C.2. In the existing protocol, an aperiodic SRS resource set includes one or more SRS resources, and these multiple SRS resource sets are in the same slot. The higher layer configures an offset k and an offset t of the available slot (i.e., the index of the effective slot) for the SRS resource set. When there are multiple configured t, one of the t is determined according to DCI. This SRS set is sent in the t-th available slot after the second reference slot (distinct from the reference slot in the multiple slots occupied by the SRS mentioned above; the reference slot in the multiple slots occupied by the SRS mentioned above can be called the first reference slot), where the reference slot is... or Where μ SRS ,μ PDCCH ,μ offset,PDCCH ,μ offset,SRS , The parameters are, in order: SRS subcarrier parameters, PDCCH subcarrier parameters, PDCCH parameters, SRS parameters, PDCCH parameters, and SRS parameters. The DCI that schedules this aperiodic SRS resource set is in slot n. Here, slot n is related to the slot where the DCI that triggers the aperiodic SRS resides. Figures 3-5 In this context, slot n can be different slots, such as those used in scheduling. Figure 3 The DCI of SRS resource1 can be in slot n, or in a slot before slot n, for example... Figure 11In slot nk, the existing available slot is determined based on the aperiodic SRS resource set, that is, all time-domain symbols in this available slot corresponding to this aperiodic SRS resource set are uplink symbols, and the interval between them and the DCI is greater than or equal to a predetermined value.

[0178] When an SRS in an SRS resource can transmit multiple time-domain symbols in more than one slot, k cannot be configured at the SRS resource set level; it should be configured at the SRS resource level. In some cases, multiple k values ​​may need to be configured for a single SRS resource, as in scheme A.3 above. That is, the k value is configured separately for each slot within the multiple slots occupied by an SRS resource. Alternatively, for multiple SRS resources in an SRS resource set, only one k value can be configured as an absolute value (similar to the reference slot in scheme A.3), while the others are offset values ​​relative to this absolute value, i.e., relative values.

[0179] The method for determining available slots in non-periodic SRS also needs to be changed, based on the SRS resource set. One or more of the following methods can be used:

[0180] Option D.1: Determine available slots at the SRS resource level. In this approach, some SRS resources in an SRS resource set can find available slots for transmission, while others cannot. Resources that find available slots are transmitted, while those that don't are not. Rules must be established to prevent multiple SRS resources from finding the same time domain symbol. For example, the search order can be specified, such as based on the first predetermined parameter of the SRS resource and / or signaling information notified by the base station. If a later-searched SRS resource 2 and an earlier SRS resource 1 find the same time domain symbol, then SRS resource 2 will continue searching for available slots. Alternatively, an additional constraint can be added to the available slots of the later-searched SRS resource 2: the time domain symbol index of SRS resource 2 in this slot cannot be a time domain symbol already occupied by an SRS resource that has found an available slot. In other words, either an SRS resource is not transmitted, or when transmission is required, it is transmitted in each of the multiple slots within this SRS resource. For example, the first predefined parameter includes at least one of the following: the SRS resource index, k configured in the SRS resource, and t configured in the SRS resource.

[0181] Option D.2: Available slots are determined at the slot level. This means that some SRS resources in the SRS resource set may only have some slots sent, not all of them. In other words, some SRS resources in the SRS resource set only send within a portion of the multiple slots corresponding to that SRS resource. Alternatively, although available slots are determined per slot, each slot within multiple slots of an SRS resource needs to find an available slot before sending. For example, multiple slots of this SRS resource might correspond to different k values, with k values ​​increasing sequentially, and the increment step can be a predefined or configured value. Similar to Option D.1, the order of available slots for each SRS resource in the SRS resource set needs to be determined. The order in which valid time slots corresponding to multiple time slots of an SRS resource are found also needs to be determined. For example, an SRS resource might correspond to multiple time slots, with each time slot corresponding to a valid time slot. The multiple time slots include time slot 1 and time slot 2. The effective time slot 2 of the later-found time slot 2 can be increased by at least one of the following: the time domain symbol index of time slot 2 in this slot that belongs to multiple time domain symbols cannot be the time domain symbol occupied by time slot 1 that has already found an available slot. The time domain symbol index of each time slot that belongs to multiple time domain symbols is determined according to scheme A.1 and scheme A.2 in the above scheme.

[0182] Option D.3: Determine available slots at the SRS resource set level. This means that an available slot is found only when all slots corresponding to all SRS resources in the SRS resource set are available slots. In other words, at this point, the SRS resource set either does not send any data or all SRS resources in the set need to be sent. This option also requires determining the search order for available slots of multiple SRS resources in the SRS resource set, just like Option D.1.

[0183] In the above schemes D.1 to D.3, the search order for available slots of multiple SRS resources in the SRS resource set needs to be specified. In another implementation, the starting slot's 'k' is configured in all slots corresponding to multiple SRS resources in this SRS resource set, and different slots in all slots correspond to different 't' values. This way, available slots are determined according to their respective 't' values, starting from the same reference slot. For example, 'k' is configured at the SRS resource set level, and each slot in all slots is configured with its own 't' value, or it is agreed that the 't' values ​​in all slots increase according to the second predetermined parameter of the SRS. In schemes D.1 to D.3, the reference signal is an aperiodic reference signal. This embodiment does not exclude the case where the periodic or semi-persistent reference signal determines at least two time slots where the reference signal is located based on the index of the effective time slot. In this case, any one of schemes D.1 to D.3 can be used to determine at least two time slots. In this case, the second reference time slot can be a time slot determined based on the period and the period offset. In schemes D.1 to D.3, at least one of the following limitations can be further imposed: the actual time-domain interval of multiple time slots corresponding to one SRS resource is less than or equal to a first predetermined value; the actual time-domain interval of multiple time slots corresponding to one SRS resource set is less than or equal to a second predetermined value. Preferably, the first predetermined value is less than or equal to the second predetermined value. This is because it is necessary to consider the limited time length for maintaining the consistency of certain parameters when the terminal transmits SRS, the time span of multiple time slots is limited when the receiving end performs joint reception of signals from multiple time slots, and the channel coherence time is also limited. The first and second predetermined values ​​can be determined based on the values ​​configured in the base station signaling information, or they can be determined based on the capability information reported by the terminal.

[0184] In the above scheme, an SRS resource maintains phase continuity or consistency across multiple time-domain symbols in its occupied slots, and / or transmit power consistency, and / or identical transmit beams, and / or identical timing advance parameters, and / or identical transmit power.

[0185] In the case of an SRS resource being a periodic or semi-persistent SRS resource, the multiple slots occupied by an SRS resource are the multiple slots occupied by the SRS within a period.

[0186] When an SRS resource is an aperiodic SRS resource, the multiple slots occupied by an SRS resource are the multiple slots occupied by the SRS in a single aperiodic trigger.

[0187] In the above scheme, an SRS resource occupies multiple time-domain symbols in multiple slots. In one embodiment, the multiple time-domain symbols meet the agreed conditions.

[0188] Example 2: Configure multiple SRS resources to form an SRS resource group. The SRS resources within an SRS resource group are interconnected. This achieves the characteristics of Example 1 (Scheme 1). In Example 2 (Scheme 2), one SRS resource group is equivalent to one SRS resource in Scheme 1. An SRS resource set includes one or more SRS resource groups. For example, parameters configured or determined at the resource level in Scheme 1 can be changed to resource group level configurations or determinations, and parameters configured or determined at the slot level can be changed to resource level configurations within a resource group. An SRS resource set includes one or more SRS resource groups, and each SRS resource group is always treated as a whole to achieve fast uplink channel scanning. For example, multiple SRS resources within an SRS resource group may share the same SRS port. Schemes 1 and 2 are two schemes, differing only in the logical structure of parameter configuration; the achieved results are equivalent.

[0189] In Scheme 2, an SRS resource group maintains phase continuity or consistency, and / or transmit power consistency, and / or transmit beam identical, and / or time advance parameter identical, and / or transmit power identical across multiple time-domain symbols in its occupied slots.

[0190] In the case of an SRS resource group being a periodic or semi-persistent SRS resource, the multiple slots occupied by an SRS resource group are the multiple slots occupied by the SRS within a period.

[0191] When an SRS resource is an aperiodic SRS resource, the multiple slots occupied by an SRS resource are the multiple slots occupied by the SRS resource in a single aperiodic trigger.

[0192] In this application, an SRS resource includes one or more SRS ports and is configured with time-domain resources, frequency-domain resources, and code-domain resources occupied by the SRS. It is an independent configuration logic unit of the SRS. Different SRS resources can be configured with different numbers of ports, time-domain resources, frequency-domain resources, and code-domain resources.

[0193] Examples one and two above describe the scenario where one SRS resource or one SRS resource group occupies multiple slots. The same approach can be used for scenarios where other signals occupy multiple slots, simply replacing the SRS with other signals. These other signals include at least one of the following: a reference signal, a channel signal, where the reference signal includes at least one of the following: downlink DMRS, uplink DMRS, uplink PRACH signal, downlink synchronization signal, downlink CSI-RS, uplink PT-RS, and downlink PT-RS. If it is a downlink reference signal, replace "transmit" with "receive," and "receive" with "transmit." Replace "terminal" with "base station," and "base station" with "terminal." The reference signal carries no information, or only a small amount of information, primarily to allow the receiver to obtain channel characteristics based on the reference signal. The channel signal carries information sent from the transmitter to the receiver, and is generally demodulated using a demodulation reference signal. When the signal is a reference signal, the signal in a reference signal unit includes the reference signal on each of the multiple reference signal ports included in that reference signal unit. When the signal is a channel signal, a signal unit is a channel signal on each demodulation reference signal port in one or more demodulation reference signal ports. One channel signal unit includes one transmission of the channel signal, one channel signal is scheduled by the same signaling, such as by the same DCI, and / or different channel signals in a channel signal unit carry part of the information of a message, or different channel signals in a channel signal unit are repeated transmissions of the same information.

[0194] In the above example, a time slot is just a time unit, but it can also be other names, or the time slot can be replaced with other future time units. One time slot includes 14 or 13 consecutive time domain symbols. A time slot can also be a resource scheduling unit or a parameter configuration unit. For example, other time units include more than 14 or less than 13 consecutive time domain symbols. Other future time units can also be a resource scheduling unit or a parameter configuration unit.

[0195] The above describes the signal transmission between the terminal and the base station. This embodiment does not exclude the possibility of two terminal devices transmitting signals in the same way. For example, in a sidelink scenario, the terminal described above can be replaced with the first terminal and the base station can be replaced with the second terminal.
