[0002] Sounding Reference Signal (SRS) is an important reference signal in communication systems and is widely used in various functions in communication systems. For example, SRS can be used for non-codebook based transmission, where the network device can configure a non-codebook based physical downlink shared channel (PDSCH) transmission mode, in which the network device performs uplink channel estimation based on the SRS sent by the terminal device and determines the precoding of the downlink transmission based on the channel reciprocity.

[0003] Then, when the wireless channel changes rapidly, especially in the case of high-speed movement, the precoding obtained based on the uplink channel estimation result and the PDSCH may be mismatched, thereby affecting the transmission performance of the PDSCH. Summary of the invention

[0082] In order to facilitate a better understanding of the embodiments of the present application, the relevant knowledge of the embodiments of the present application will be explained below.

[0083] 1. Introduction to SRS Resources

[0084] In the NR system, SRS can be used for beam management, codebook-based transmission, non-codebook-based transmission, and antenna switching. The network device can configure one or more SRS resource sets (SRS Resource set) to the terminal device through high-level signaling. Each SRS resource set can include one or more SRS resources (SRS resource). The configuration of each SRS resource set includes: the purpose of the SRS resource set, periodic characteristics (periodic, semi-persistent, and non-periodic) and other configurations.

[0085] 2. Time Domain Resources and Antenna Ports of SRS Resources

[0086] In NR Release-15 or 16, within a time slot, the SRS resource can occupy the last 6 symbols, and the number of SRS symbols Ns configurable by high-level signaling is {1, 2, 4}, and supports comb-2 and comb-4 structures in the frequency domain, where the number of repetitions R supported is {1, 2, 4}. In Release-17, within a time slot, the symbol starting position of the SRS resource can be on any symbol within a time slot, and the number of symbols Ns that SRS can occupy is increased to {1, 2, 4, 8, 10, 12, 14} symbols, and the comb-8 structure is also supported. In addition, the number of repetitions R supported is also increased to {1, 2, 4, 5, 6, 7, 8, 10, 12, 14}.

[0087] Currently, each SRS resource can have 1, 2 or 4 antenna ports, and each antenna port occupies the same SRS resource. The SRSs of multiple terminal devices can be time division multiplexed (Time Division Multiplex and Multiplexer, TDM) in one slot, or frequency division multiplexed (FDM) through a comb structure.

[0088] 3. SRS Sequence

[0089] The base sequence of the SRS resource is the Zadoff-Chu (ZC) sequence, which is distinguished from each other by the orthogonality of the ZC sequence. The concept of cyclic shift (CS) is introduced when generating the SRS sequence. For the comb-2 structure, the maximum number of cyclic shifts is defined as 8; for the comb-4 structure, the maximum number of cyclic shifts is defined as 12; for the comb-8 structure, the maximum number of cyclic shifts is defined as 6.

[0090] According to the protocol TS38.211, the antenna port p i The SRS sequence sent is as follows:

[0091]

[0092]

[0093]

[0094] in, is the length of the SRS sequence;

[0095] is an SRS sequence, which is generated based on a ZC sequence;

[0096] is the number of consecutive symbols of SRS;

[0097] δ=log2(K TC ), K TC ∈{2,4,8}, K TC is the frequency comb value corresponding to the comb structure;

[0098] α i is the antenna port p i Circular shift of

[0099] The SRS sequence is divided into 30 sequence groups, each of which contains 2 sequences. u is the index or identifier of the sequence group, and the value of u is 0 to 29. v is the index or identifier of the two sequences in the sequence group, and the value is 0 or 1.

[0100] 4. Cycle Characteristics of SRS Resources

[0101] There are three types of periodic characteristics of SRS resources: periodic, semi-persistent and non-periodic. Based on this, SRS resources are divided into: periodic SRS resources, semi-persistent SRS resources and non-periodic SRS resources.

[0102] Periodic SRS resources refer to SRS resources that are transmitted periodically, and their period and slot offset are configured by Radio Resource Control (RRC) signaling. Once the terminal device receives the corresponding configuration parameters, it sends SRS resources at a certain period until the RRC configuration becomes invalid.

[0103] The spatial relationship (Spatial Relation) information of the periodic SRS resources is also configured by RRC signaling. The spatial relationship information can indicate a Channel State Information Reference Signal (CSI-RS), a synchronization signal / physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) or a reference SRS. For example, the transmit beam of the periodic SRS resource can be indicated in an implicit manner. For example, the terminal device determines the transmit beam of the periodic SRS resource based on the indicated CSI-RS / SSB. For another example, the terminal device can determine the transmit beam used to transmit the SRS on the SRS resource through the spatial relationship information of the SRS resource.

[0104] In the embodiment of the present application, spatial relationship information is also referred to as spatial relationship or spatial related information.

[0105] Semi-persistent SRS resources are also periodically transmitted SRS resources. Their period and time slot offset are configured by RRC signaling, but their activation and deactivation signaling are carried by the media access layer control element (MAC Control Element, MAC CE). The terminal device starts to transmit SRS after receiving the activation signaling until it receives the deactivation signaling. The spatial relationship information of the semi-persistent SRS can be carried together with the MAC CE that activates the SRS.

[0106] Aperiodic SRS resources refer to SRS resources triggered by downlink control information (DCI). The bandwidth, frequency domain position, comb structure, etc. of aperiodic SRS resources can also be configured in advance through RRC signaling.

[0107] The DCI used to trigger non-periodic SRS resources can be carried by the DCI used to schedule the physical uplink shared channel (PUSCH) / PDSCH in the dedicated search space of the terminal device or the common search space (Common Search Space), or by DCI format 2_3 in the common search space.

[0108] After receiving the DCI for triggering the non-periodic SRS resource, the terminal device transmits the SRS on the SRS resource group indicated by the DCI. The slot offset between the DCI and the non-periodic SRS resource can be configured by high-level signaling, such as RRC signaling. In addition, for the non-periodic SRS resource, the terminal device can also determine the transmit beam used to transmit the SRS on the resource through the spatial relationship information of the resource.

[0109] In the related technology, since the current uplink channel estimation result is obtained based on the SRS resources transmitted at the time of SRS resource transmission, and then the downlink transmission precoding is performed based on the uplink channel estimation result, when the wireless channel changes rapidly, especially in the case of high-speed movement, the precoding and PDSCH will be mismatched. In other words, the wireless channel when transmitting PDSCH may have undergone a significant change compared to the wireless channel when transmitting SRS. If the precoding obtained based on the channel estimation result at the previous SRS resource transmission time is still used, it will affect the transmission performance of PDSCH.

[0110] An embodiment of the present application proposes that a terminal device sends SRS resources at multiple sending opportunities, and some or all of these sending opportunities are associated with each other. The sending opportunities with the associated relationship can be jointly used for channel prediction, and then the precoding calculation of subsequent downlink transmission is performed based on the channel prediction result. Since the channel prediction is a prediction of the wireless channel in a subsequent time, even if the wireless channel changes rapidly, the precoding of the downlink transmission based on the channel prediction result will be more matched with the wireless channel at the subsequent PDSCH transmission moment, thereby improving the transmission performance of the PDSCH.

[0111] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0112] Figure 2 An interactive flow chart of a method for transmitting a sounding reference signal provided in an embodiment of the present application, the method can be executed by a terminal device or a network device, such as Figure 2 As shown, the method may include:

[0113] S210: The terminal device sends SRS resources to the network device at P sending opportunities, and the P sending opportunities include: at least one of a first associated opportunity group and a second associated opportunity group, and P is an integer greater than 1; wherein, a first associated relationship exists among multiple sending opportunities in the first associated opportunity group, and the multiple sending opportunities in the first associated opportunity group correspond to one or more SRS resources; a second associated relationship exists among multiple sending opportunities in the second associated opportunity group, and the multiple sending opportunities in the second associated opportunity group correspond to one SRS resource.

[0114] In some implementations, SRS resources may also be referred to as SRS, which is not limited in the embodiments of the present application.

[0115] In some implementations, the first transmission opportunity may include: one or more orthogonal frequency division multiplexing (OFDM) symbols.

[0116] In some implementations, the second transmission opportunity may include: one or more OFDM symbols.

[0117] It should be understood that in the embodiment of the present application, OFDM symbols are also referred to as symbols for short, and the embodiment of the present application does not limit this.

[0118] In the embodiment of the present application, the first association opportunity group is divided into the following two situations:

[0119] Case 1: multiple transmission opportunities in the first associated opportunity group correspond to one SRS resource.

[0120] In other words, the SRS resources corresponding to the multiple transmission opportunities in the first associated opportunity group are the same, that is, the same SRS resource is transmitted on the multiple transmission opportunities in the first associated opportunity group.

[0121] Case 2: multiple transmission opportunities in the first associated opportunity group correspond to multiple SRS resources.

[0122] For example, a plurality of transmission opportunities in the first associated opportunity group correspond to different SRS resources respectively, that is, different SRS resources are transmitted at a plurality of transmission opportunities in the first associated opportunity group respectively.

[0123] The following will describe the first case of the first association timing group in detail:

[0124] In some implementations, when the multiple transmission opportunities in the first associated opportunity group correspond to one SRS resource, the multiple transmission opportunities in the first associated opportunity group include: a first transmission opportunity and at least one second transmission opportunity;

[0125] The first sending opportunity is any of the following:

[0126] A sending opportunity among periodic sending opportunities;

[0127] A sending opportunity in a semi-persistent sending opportunity;

[0128] Non-periodic sending timing;

[0129] The second sending opportunity is any of the following:

[0130] A sending opportunity among periodic sending opportunities;

[0131] A sending opportunity in a semi-persistent sending opportunity;

[0132] Aperiodic sending timing.

[0133] It should be understood that the periodic sending opportunity refers to the sending opportunity that occurs periodically; the semi-continuous sending opportunity refers to the sending opportunity that occurs periodically after activation based on MAC CE activation; the non-periodic sending opportunity refers to the sending opportunity that occurs based on DCI triggering.

[0134] In some possible implementations, when the SRS resource is a periodic SRS resource, the first sending opportunity is a periodic sending opportunity; when the SRS resource is a semi-persistent SRS resource, the first sending opportunity is a semi-persistent sending opportunity; when the SRS resource is a non-periodic SRS resource, the first sending opportunity is a non-periodic sending opportunity.

[0135] It should be understood that if there are multiple second sending opportunities, then for each second sending opportunity in the multiple second sending opportunities, the second sending opportunity may be any one of the following:

[0136] A sending opportunity among periodic sending opportunities;

[0137] A sending opportunity in a semi-persistent sending opportunity;

[0138] Aperiodic sending timing.

[0139] In some possible implementations, if the first sending opportunity is a sending opportunity among periodic sending opportunities or a sending opportunity among semi-continuous sending opportunities, and the second sending opportunity is a sending opportunity among periodic sending opportunities or a sending opportunity among semi-continuous sending opportunities, then the sending periods of the first sending opportunity and the second sending opportunity may be the same or different.

[0140] It should be understood that, assuming that the first transmission opportunity is regarded as the basic transmission opportunity, the second transmission opportunity can be understood as an additional transmission opportunity on top of the basic transmission opportunity. The basic transmission opportunity refers to the transmission opportunity of the SRS resource determined according to the occupied symbol position of the SRS resource and the RRC parameter SRS-PeriodicityAndOffset.

[0141] In some implementations, the second transmission timing is associated with the first transmission timing by default, that is, a first association. It can also be understood that the first transmission timing and the second transmission timing are used together by default to perform channel prediction, or as a basis for enabling a channel prediction function.

[0142] The first association timing group is exemplarily described below:

[0143] For example, Figure 3 A schematic diagram of a first association timing group provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the first sending opportunity is a sending opportunity in the periodic sending opportunities, the second sending opportunity is a non-periodic sending opportunity, and the first associated opportunity group includes: a second sending opportunity and a first sending opportunity closest to the second sending opportunity.

[0144] For example, Figure 4 A schematic diagram of another first association timing group provided in an embodiment of the present application, such as Figure 4 As shown, the first sending opportunity is a sending opportunity in the periodic sending opportunities, and the second sending opportunity is a sending opportunity in the periodic sending opportunities. In this case, there are multiple first associated opportunity groups, and each first associated opportunity group includes: a second sending opportunity and the first sending opportunity closest to the second sending opportunity.

[0145] For example, Figure 5 A schematic diagram of another first association timing group provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the first sending opportunity is a non-periodic sending opportunity, and the second sending opportunity is a non-periodic sending opportunity. In this case, the first associated machine group includes: the second sending opportunity and the first sending opportunity.

[0146] For example, Figure 6 A schematic diagram of another first association timing group provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the first transmission opportunity is a non-periodic transmission opportunity, and the second transmission opportunity is a transmission opportunity in the periodic transmission opportunity. In this case, the first associated machine group includes: the first transmission opportunity and the second transmission opportunity closest to the first transmission opportunity.

[0147] It should be understood that Figures 3 to 6 The first associated timing groups shown in the figure all include one second sending timing. In fact, the first associated timing group may include multiple second sending timings. This situation will be exemplarily described below by way of example:

[0148] For example, Figure 7 A schematic diagram of a first association timing group provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the first sending opportunity is a sending opportunity in the periodic sending opportunities, each second sending opportunity is a non-periodic sending opportunity, and the first associated opportunity group includes: two second sending opportunities and the first sending opportunity closest to the two second sending opportunities.

[0149] For example, Figure 8 A schematic diagram of another first association timing group provided in an embodiment of the present application, such as Figure 8 As shown, the first sending opportunity is a sending opportunity in the periodic sending opportunities, and each second sending opportunity is a sending opportunity in the periodic sending opportunities. In this case, there are multiple first associated opportunity groups, and each first associated opportunity group includes: two second sending opportunities and the first sending opportunity closest to the two second sending opportunities.

[0150] For example, Fig. 9 A schematic diagram of another first association timing group provided in an embodiment of the present application is shown in FIG. Fig. 9 As shown, the first transmission opportunity is a non-periodic transmission opportunity, and each second transmission opportunity is a non-periodic transmission opportunity. In this case, the first associated machine group includes: two second transmission opportunities and the first transmission opportunity.

[0151] For example, Fig.10 A schematic diagram of another first association timing group provided in an embodiment of the present application is shown in FIG. Fig.10 As shown, the first sending opportunity is a non-periodic sending opportunity, and each second sending opportunity is a sending opportunity in the periodic sending opportunity. In this case, the first associated machine group includes: the first sending opportunity and the two second sending opportunities closest to the first sending opportunity, wherein the two second sending opportunities belong to different periodic sending opportunities.

[0152] It should be understood that if the first association opportunity group includes multiple second transmission opportunities, the types of the multiple second transmission opportunities may be the same. Figures 6 to 10 In each example shown, the types of the two second transmission opportunities are the same. For example, they are either periodic transmission opportunities or non-periodic transmission opportunities. Of course, the types of the multiple second transmission opportunities may also be different.

[0153] For example, Fig.11A schematic diagram of a first association timing group provided in an embodiment of the present application is shown in FIG. Fig.11 As shown, the first sending opportunity is one of the periodic sending opportunities, and there are two second sending opportunities, wherein one second sending opportunity is a non-periodic sending opportunity and the other second sending opportunity is a periodic sending period. In this case, there are multiple first associated opportunity groups. Among them, the first first associated opportunity group includes: two second sending opportunities and the first sending opportunity closest to the two second sending opportunities, wherein one of the two second sending opportunities is a non-periodic sending opportunity and the other is one of the periodic sending opportunities. The remaining first associated opportunity groups except the first first associated opportunity group include: one second sending opportunity and the first sending opportunity closest to the second sending opportunity, wherein the second sending opportunity is one of the periodic sending opportunities.

[0154] It should be understood that since the semi-continuous sending opportunity is similar to the periodic sending opportunity, based on this, the example of the first associated timing group when the first sending opportunity and / or the second sending opportunity is a sending opportunity of the semi-continuous sending opportunity is similar to the example of the first associated timing group when the first sending opportunity and / or the second sending opportunity is a sending opportunity of the periodic sending opportunity, and the embodiments of the present application will not repeat them.

[0155] The time domain relationship between the first sending opportunity and the second sending opportunity is described below:

[0156] In some implementations, at least one second sending opportunity and the first sending opportunity in the first associated opportunity group satisfy any of the following:

[0157] The at least one second transmission opportunity is located in the same time slot as the first transmission opportunity;

[0158] The at least one second sending opportunity is separated from the first sending opportunity by M1 time slots, where M1 is an integer.

[0159] For example, Fig.12 A time domain relationship diagram provided in an embodiment of the present application, such as Fig.12 As shown, the first transmission opportunity and the second transmission opportunity are located in the same time slot.

[0160] For example, Fig.13 Another time domain relationship diagram provided in an embodiment of the present application, wherein: Fig.13 and Fig.12 The difference is that Fig.13 The first sending opportunity includes two second sending opportunities, and the first sending opportunity and the two second sending opportunities are located in the same time slot.

[0161] Of course, if the first associated timing group includes a first transmission timing and multiple second transmission timings, the first transmission timing may be located in the same time slot as some of the multiple second transmission timings, and in a different time slot from the remaining second transmission timings.

[0162] It should be understood that the at least one second sending opportunity is separated from the first sending opportunity by M1 time slots, and M1=0, which means that the first sending opportunity is adjacent to the at least one second sending opportunity time slot.

[0163] For example, Fig.14 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.14 As shown, the time slot to which the first transmission opportunity belongs is adjacent to the time slot to which the second transmission opportunity belongs.

[0164] For example, Fig.15 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.15 As shown, the time slot to which the first transmission opportunity belongs and the time slot to which the second transmission opportunity belongs are separated by one time slot, that is, M1=1.

[0165] In some implementations, when the first associated timing group includes multiple second transmission timings, the multiple second transmission timings being separated from the first transmission timing by M1 time slots means that the first second transmission timing among the multiple second transmission timings is separated from the first transmission timing by M1 time slots.

[0166] For example, Fig.16 A time domain relationship diagram provided in an embodiment of the present application, such as Fig.16 As shown, there are two second transmission opportunities, and the time slot to which the first transmission opportunity belongs is adjacent to the time slot to which the first second transmission opportunity belongs.

[0167] For example, Fig.17 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.17 As shown, there are two second transmission opportunities, and the time slot to which the first transmission opportunity belongs and the time slot to which the first second transmission opportunity belongs are separated by one time slot, that is, M1=1.

[0168] In some implementations, when the first transmission opportunity is a transmission opportunity in the periodic transmission opportunities or a transmission opportunity in the semi-persistent transmission opportunities, M1 satisfies any of the following:

[0169] M1 is 1 / K of the transmission period of the first transmission opportunity, where K is an integer greater than 1;

[0170] M1 is the difference between the transmission period of the first transmission opportunity and X time slots, where X is a positive integer.

[0171] For example, the transmission period of the first transmission opportunity is 2 time slots, K=2, and then M1=1.

[0172] For example, the transmission period of the first transmission opportunity is 3 time slots, X=1, and then M1=2.

[0173] In some implementations, the at least one second sending opportunity and the first sending opportunity further satisfy:

[0174] The at least one second transmission opportunity is separated from the first transmission opportunity by N1 symbols, where N1 is an integer.

[0175] It should be understood that, if N1=0, then the at least one second transmission opportunity being N1 symbols apart from the first transmission opportunity means that the at least one second transmission opportunity is adjacent to the first transmission opportunity.

[0176] For example, Fig.18 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.18 As shown, the occupied symbol of the first transmission opportunity and the occupied symbol of the second transmission opportunity are adjacent.

[0177] For example, Fig.19 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.19 As shown, there is a gap of one symbol between the occupied symbol of the first transmission opportunity and the occupied symbol of the second transmission opportunity.

[0178] In some implementations, when the first associated timing group includes multiple second transmission timings, the multiple second transmission timings being N1 symbols apart from the first transmission timing means that the first second transmission timing among the multiple second transmission timings is N1 symbols apart from the first transmission timing.

[0179] For example, Fig. 20 A time domain relationship diagram provided in an embodiment of the present application, such as Fig. 20 As shown, there are two second transmission opportunities, and the symbol occupied by the first transmission opportunity is adjacent to the symbol occupied by the first second transmission opportunity.

[0180] For example, Fig.21 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.21 As shown, there are two second transmission opportunities, and the symbol occupied by the first transmission opportunity and the symbol occupied by the first second transmission opportunity are separated by 1 symbol, that is, N1=1 as mentioned above.

[0181] In some implementations, when the at least one second sending opportunity is a plurality of second sending opportunities, the plurality of second sending opportunities satisfy any of the following:

[0182] The time slots to which the multiple second transmission opportunities belong are the same;

[0183] Multiple second transmission opportunities are spaced apart by M2 time slots, where M2 is an integer.

[0184] For example, Fig.13 As shown, multiple second transmission opportunities belong to the same time slot.

[0185] It should be understood that Fig.13 The first sending opportunity and the two second sending opportunities are located in the same time slot. Of course, in an embodiment of the present application, multiple second sending opportunities are located in the same time slot, and the first sending opportunity can be located in a different time slot from the multiple second sending opportunities.

[0186] It should be understood that when M2=0, it means that the time slots to which the multiple second transmission opportunities belong are adjacent.

[0187] For example, Fig. 22 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig. 22 As shown, there are two second transmission opportunities, and the time slots to which the two second transmission opportunities belong are adjacent.

[0188] For example, Fig.23 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.23 As shown, there are two second sending opportunities, and the two second sending opportunities are separated by one time slot, that is, M2=1.

[0189] It should be understood that if M1=M2, it means that the time interval between the first transmission opportunity and the first second transmission opportunity among the multiple second transmission opportunities is the same as the time interval between the multiple second transmission opportunities. This is beneficial to the implementation of the channel prediction algorithm, including improving the performance of the channel prediction or reducing the complexity of the channel prediction.

[0190] For example, Fig.24 A time domain relationship diagram provided in an embodiment of the present application, such as Fig.24 As shown, there are two second transmission opportunities, the interval between the first transmission opportunity and the first second transmission opportunity is 1 time slot, and the interval between the two second transmission opportunities is 1 time slot.

[0191] In some implementations, the multiple second transmission opportunities further satisfy: the multiple second transmission opportunities are spaced apart by N2 symbols, where N2 is an integer.

[0192] It should be understood that if N2=0, it means that the symbols occupied by the multiple second transmission opportunities are adjacent.

[0193] For example, Fig.25Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.25 As shown, there are two second transmission opportunities, and the symbols occupied by the two second transmission opportunities are adjacent.

[0194] For example, Fig.26 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.26 As shown, there are two second transmission opportunities, and the symbol interval between the two second transmission opportunities is 1 symbol.

[0195] It should be understood that if N1=N2, it means that the time interval between the first transmission opportunity and the first second transmission opportunity among the multiple second transmission opportunities is the same as the time interval between the multiple second transmission opportunities. This is beneficial to the implementation of the channel prediction algorithm, including improving the performance of the channel prediction or reducing the complexity of the channel prediction.

[0196] For example, Fig. 27 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig. 27 As shown, there are two second transmission opportunities, the interval between the first transmission opportunity and the first second transmission opportunity is 1 symbol, and the interval between the two second transmission opportunities is 1 symbol.

[0197] In some implementations, for a second transmission opportunity among the at least one second transmission opportunity, a time interval between the second transmission opportunity and the first transmission opportunity closest to it before and a time interval between the second transmission opportunity and the first transmission opportunity closest to it after may be the same.

[0198] In some possible implementations, the time interval may be a time interval between time slots or a time interval between symbols, which is not limited in the embodiments of the present application.

[0199] For example, Fig.28 A time domain relationship diagram provided in an embodiment of the present application, such as Fig.28 As shown, the first associated timing group includes: a first sending timing and a second sending timing, wherein the interval between the second sending timing and the time slot to which the first sending timing belongs is 1 time slot, and the interval between the second sending timing and the time slot to which the next first sending timing belongs is also 1 time slot.

[0200] For example, Fig.29 Another time domain relationship diagram provided in the embodiment of the present application is as follows: Fig.29As shown, the first associated timing group includes: a first sending timing and a second sending timing, wherein the interval between the second sending timing and the symbol occupied by the first sending timing is 1 symbol, and the interval between the second sending timing and the symbol occupied by the nearest first sending timing thereafter is also 1 symbol.

[0201] It should be understood that the reason why the above-mentioned time relationship is satisfied between the first sending opportunity and the second sending opportunity and between the multiple second sending opportunities is to adapt to the channel prediction algorithm, thereby facilitating channel prediction.

[0202] In some implementations, for any second transmission opportunity in the first associated opportunity group, the number of occupied symbols of the second transmission opportunity is the same as or different from that of the first transmission opportunity.

[0203] For example, it is assumed that the first associated timing group includes: a first transmission timing and a second transmission timing, wherein the number of occupied symbols of the first transmission timing and the second transmission timing are both four.

[0204] For example, it is assumed that the first associated timing group includes: a first transmission timing and a second transmission timing, wherein the number of symbols occupied by the first transmission timing is 4, and the number of symbols occupied by the second transmission timing is 2.

[0205] It should be understood that if the first associated opportunity group includes multiple second transmission opportunities, the number of occupied symbols of the multiple second transmission opportunities may be the same or different.

[0206] For example, it is assumed that the first associated timing group includes two second transmission timings, wherein the number of occupied symbols of the two second transmission timings is four.

[0207] For example, it is assumed that the first associated timing group includes two second transmission timings, wherein one second transmission timing occupies four symbols, and the other second transmission timing occupies two symbols.

[0208] In some implementations, for any second transmission opportunity in the first associated opportunity group, when the number of occupied symbols of the second transmission opportunity is different from the number of occupied symbols of the first transmission opportunity, the number of occupied symbols of the second transmission opportunity is determined by the first signaling.

[0209] In some possible implementations, the first signaling may be RRC signaling, or DCI signaling, etc., which is not limited in the embodiments of the present application.

[0210] In some implementations, the first signaling may directly or indirectly indicate the number of occupied symbols of the second transmission opportunity. For example, the first signaling may carry the number of occupied symbols of the second transmission opportunity. For another example, the length of a certain field in the first signaling may indirectly indicate the number of occupied symbols of the second transmission opportunity.

[0211] In some implementations, for any second transmission opportunity in the first associated opportunity group, when the number of occupied symbols of the second transmission opportunity is different from the number of occupied symbols of the first transmission opportunity, the number of occupied symbols of the second transmission opportunity may also be determined by a default rule. For example, the default rule stipulates that the number of occupied symbols of the second transmission opportunity is the number of occupied symbols of the first transmission opportunity plus one.

[0212] In some possible implementations, for any second sending opportunity in the first associated opportunity group, when the number of occupied symbols of the second sending opportunity is the same as the number of occupied symbols of the first sending opportunity, the number of occupied symbols of the second sending opportunity is also determined by RRC signaling or DCI signaling.

[0213] In some implementations, for any second transmission opportunity in the first associated opportunity group, when the number of occupied symbols of the second transmission opportunity is the same as the number of occupied symbols of the first transmission opportunity, the number of occupied symbols of the second transmission opportunity may also be determined by a default rule. For example, the default rule stipulates that the number of occupied symbols of the second transmission opportunity is the same as that of the first transmission opportunity.

[0214] In some implementations, for any second sending opportunity in the first associated opportunity group, when the second sending opportunity is a non-periodic sending opportunity, the second sending opportunity is triggered by DCI.

[0215] In some implementations, the reference time of the second sending opportunity is any one of the following: the transmission time of the DCI used to trigger the second sending opportunity; the first sending opportunity in the first associated opportunity group.

[0216] In some implementations, the transmission time of the DCI may be the reception time or the sending time of the DCI.

[0217] In some possible implementations, the reference time of the second sending opportunity may be the end time or the start time of the transmission time of the DCI, that is, the first symbol or the last symbol of the physical downlink control channel (PDCCH) carrying the DCI, or when the PDCCH carrying the DCI occupies multiple symbols, the reference time of the second sending opportunity may be one of the multiple symbols, and the embodiments of the present application do not impose any restrictions on this.

[0218] In some implementations, the time offset of the second sending opportunity relative to the reference time may be the time offset of the start time of the second sending opportunity relative to the reference time, but is not limited thereto.

[0219] For example, Fig.30 A reference time diagram provided in an embodiment of the present application, such as Fig.30 As shown, the reference time of the second sending opportunity is the transmission time of the DCI used to trigger the second sending opportunity, wherein the reference time of the second sending opportunity can specifically be the end time of the transmission time of the DCI, and the time slot offset X of the second sending opportunity relative to the reference time is the time slot offset of the start time of the second sending opportunity relative to the reference time.

[0220] In some possible implementations, when the reference time of the second sending opportunity is the first sending opportunity in the first associated opportunity group, the reference time of the second sending opportunity may be the end time or the start time of the first sending opportunity in the first associated opportunity group, that is, the first symbol or the last symbol in the first sending opportunity, or when the first sending opportunity includes multiple symbols, the reference time of the second sending opportunity may be one of the multiple symbols, and the embodiments of the present application do not impose any restrictions on this.

[0221] In some implementations, the time offset of the second sending opportunity relative to the reference time may be the time offset of the start time of the second sending opportunity relative to the reference time, but is not limited thereto.

[0222] For example, Fig.31 Another reference time schematic diagram provided in the embodiment of the present application is as follows: Fig.31 As shown, the reference time of the second transmission opportunity is the end time of the first transmission opportunity, and the time slot offset X of the second transmission opportunity relative to the reference time is the time slot offset of the start time of the second transmission opportunity relative to the reference time.

[0223] In some implementations, when the at least one second transmission opportunity includes multiple non-periodic transmission opportunities, the DCIs used to trigger the multiple non-periodic transmission opportunities are the same or different.

[0224] In some implementations, the same DCI of multiple non-periodic transmission opportunities may be understood as multiple non-periodic transmission opportunities being triggered by the same DCI.

[0225] For example, it is assumed that the first associated timing group includes: two non-periodic second transmission timings, and the two non-periodic second transmission timings are both triggered by DCI 1.

[0226] In some implementations, the different DCIs of the multiple non-periodic transmission opportunities may be understood as the multiple non-periodic transmission opportunities being triggered by multiple DCIs.

[0227] In some implementations, the different DCIs of the multiple non-periodic transmission opportunities may also be referred to as the DCIs of the multiple non-periodic transmission opportunities being not completely the same.

[0228] For example, it is assumed that the first associated timing group includes: two non-periodic second transmission timings, wherein one non-periodic second transmission timing is triggered by DCI 1 , and the other non-periodic second transmission timing is triggered by DCI 2 .

[0229] For example, it is assumed that the first associated timing group includes: three non-periodic second transmission timings, wherein one non-periodic second transmission timing is triggered by DCI 1, and the other two non-periodic second transmission timings are triggered by DCI 2.

[0230] In some implementations, time offsets of the plurality of non-periodic transmission opportunities relative to corresponding reference times are configured individually or jointly.

[0231] For example, assuming that the first associated timing group includes: two non-periodic second sending timings, the network device can configure the time offsets of the two non-periodic second sending timings relative to the reference time through an RRC signaling. For example, the RRC signaling includes: the time slot offsets of the two non-periodic second sending timings relative to the reference time are 1 time slot and 2 time slots respectively.

[0232] For example, assuming that the first associated timing group includes: two non-periodic second sending timings, the network device can respectively configure the time slot offsets of the two non-periodic second sending timings relative to the reference time through two RRC signalings, for example, wherein one RRC signaling includes: the time slot offset of a certain non-periodic second sending timing relative to the corresponding reference time is 1 time slot; the other RRC signaling includes: the time slot offset of another non-periodic second sending timing relative to the corresponding reference time is 2 time slots.

[0233] In some implementations, the first transmission timing may be configured by RRC signaling, for example, the first transmission timing is determined by the occupied symbol position of the SRS resource and the RRC parameter SRS-PeriodicityAndOffset, but is not limited thereto.

[0234] In some implementations, for any second sending opportunity in the first associated opportunity group, the second sending opportunity is determined by the second signaling, or the second sending opportunity is determined by a default rule.

[0235] In some possible implementations, the second signaling may be RRC signaling, or DCI signaling, etc., which is not limited in the embodiments of the present application.

[0236] In some implementations, if the second transmission opportunity is a transmission opportunity in the periodic transmission opportunity, the second signaling may be an RRC signaling for configuring the periodic transmission opportunity. For example, the RRC signaling may be used to configure the period and slot offset of the periodic transmission opportunity. Based on this, when the periodic transmission opportunity is determined, the second transmission opportunity may be determined.

[0237] In some possible implementations, if the second sending opportunity is one of the periodic sending opportunities, and the first sending opportunity is also one of the periodic sending opportunities, for convenience, the periodic sending opportunity to which the first sending opportunity belongs can be called the first periodic sending opportunity, and the periodic sending opportunity to which the second sending opportunity belongs can be called the second periodic sending opportunity, then the second signaling can be used to indicate the time offset of the second periodic sending opportunity relative to the first periodic sending opportunity, at which time the sending periods of the two can be considered to be the same, or the second signaling can be used to indicate the time offset of the second periodic sending opportunity relative to the first periodic sending opportunity and the sending period of the second periodic sending opportunity.

[0238] For example, the second signaling indicates that the time offset of the second periodic transmission opportunity relative to the first periodic transmission opportunity is 1 time slot, and the transmission period of the second periodic transmission opportunity is the same as that of the first periodic transmission opportunity, which is 10 time slots.

[0239] In some implementations, if the second sending opportunity is one of the second periodic sending opportunities, and the first sending opportunity is one of the first periodic sending opportunities, the default rule can specify the time offset of the second periodic sending opportunity relative to the first periodic sending opportunity and the sending period of the second periodic sending opportunity.

[0240] For example, the default rule stipulates that the time offset of the second periodic transmission opportunity relative to the first periodic transmission opportunity is 1 time slot, and the transmission period of the second periodic transmission opportunity is the same as that of the first periodic transmission opportunity, which is 10 time slots.

[0241] In some implementations, if the second transmission opportunity is a non-periodic transmission opportunity, the second signaling may be an RRC signaling for configuring the non-periodic transmission opportunity. For example, the RRC signaling may be used to configure the time offset of the second transmission opportunity relative to the DCI, and the offset time slot may be determined by the RRC parameter slotOffset in the SRS-ResourceSet information element (InformationElement).

[0242] In some implementations, if the second transmission opportunity is a non-periodic transmission opportunity, the default rule may specify a time offset of the second transmission opportunity relative to the DCI.

[0243] In some implementations, if the second sending opportunity is a non-periodic sending opportunity and the first sending opportunity is a sending opportunity among periodic sending opportunities, the second signaling may be used to indicate a time offset of the second sending opportunity relative to the first sending opportunity.

[0244] For example, the second signaling indicates that the time offset of the second transmission opportunity relative to the first transmission opportunity is 1 time slot.

[0245] In some implementations, if the second sending opportunity is a non-periodic sending opportunity and the first sending opportunity is a periodic sending opportunity, the default rule may specify a time offset of the second sending opportunity relative to the first sending opportunity.

[0246] For example, the default rule stipulates that the time offset of the second transmission opportunity relative to the first transmission opportunity is 1 time slot.

[0247] In some implementations, if the second sending opportunity is a non-periodic sending opportunity and the first sending opportunity is also a non-periodic sending opportunity, the second signaling may be used to indicate a time offset of the second sending opportunity relative to the first sending opportunity.

[0248] In some implementations, if the second sending opportunity is a non-periodic sending opportunity and the first sending opportunity is also a non-periodic sending opportunity, the default rule may specify a time offset of the second sending opportunity relative to the first sending opportunity.

[0249] In some implementations, if the second sending opportunity is a sending opportunity among the periodic sending opportunities and the first sending opportunity is a non-periodic sending opportunity, the second signaling can be used to indicate the time slot offset of the second sending opportunity relative to the first sending opportunity and the sending period of the periodic sending opportunity.

[0250] For example, the second signaling indicates that the time slot offset of the second sending opportunity relative to the first sending opportunity is 1 time slot, and the sending period of the periodic sending opportunity to which the second sending opportunity belongs is 10 time slots.

[0251] In some implementations, if the second transmission opportunity is a transmission opportunity among the periodic transmission opportunities and the first transmission opportunity is a non-periodic transmission opportunity, the default rule can specify the time slot offset of the second transmission opportunity relative to the first transmission opportunity and the transmission period of the periodic transmission opportunity.

[0252] For example, the default rule stipulates that the time slot offset of the second transmission opportunity relative to the first transmission opportunity is 1 time slot, and the transmission period of the periodic transmission opportunity to which the second transmission opportunity belongs is 10 time slots.

[0253] It should be understood that since the semi-continuous sending opportunity is similar to the periodic sending opportunity, based on this, the method for determining the second sending opportunity when the first sending opportunity and / or the second sending opportunity is a sending opportunity of the semi-continuous sending opportunity is similar to the method for determining the second sending opportunity when the first sending opportunity and / or the second sending opportunity is a sending opportunity of the periodic sending opportunity, and the embodiments of the present application will not go into details about this.

[0254] In some implementations, if the first associated timing group includes multiple second sending timings, the multiple second sending timings may be determined by the same second signaling or by different second signaling, and the second signaling may be RRC signaling.

[0255] For example, if the first associated timing group includes: two second transmission timings, and the two second transmission timings are both non-periodic transmission timings, then a second signaling is used to indicate that the time offset of the two second transmission timings relative to the reference time is 1 time slot.

[0256] For example, if the first associated timing group includes: two second sending timings, and both second sending timings are non-periodic sending timings, then a second signaling is used to indicate that the time offset of one of the second sending timings relative to the corresponding reference time is 1 time slot, and another second signaling is used to indicate that the time offset of the other second sending timing relative to the corresponding reference time is 2 time slots.

[0257] For example, if the first associated timing group includes: a first sending timing and two second sending timings, and the two second sending timings are both sending timings in the periodic sending timing, and the first sending timing is also a sending timing in the periodic sending timing, then the second signaling can indicate a time offset, which is the time offset between the first sending timing and the first second sending timing and the time offset between the two second sending timings. In other words, the second signaling indicates a time offset, wherein the time interval between the first sending timing and the second sending timing is equal to the time interval between the two second sending timings, and are both equal to the time offset.

[0258] The following will describe the second situation of the first association timing group in detail:

[0259] In some implementations, when multiple transmission opportunities in the first associated opportunity group correspond to multiple SRS resources, the multiple transmission opportunities in the first associated opportunity group correspond to the multiple SRS resources one-to-one.

[0260] For example, Fig.32 A schematic diagram of the relationship between the transmission timing and the SRS resources provided in the embodiment of the present application, such as Fig.32 As shown, two SRS resources are included, namely: SRS resource 1 and SRS resource 2, and SRS resource 1 is a periodic SRS resource, SRS resource 2 is a non-periodic SRS resource, and the first associated timing group includes: two sending timings, and one sending timing is the sending timing of SRS resource 1, and the other sending timing is the sending timing of SRS resource 2.

[0261] In some implementations, when multiple transmission opportunities in the first associated opportunity group correspond to multiple SRS resources, the existence of the first associated relationship between the multiple transmission opportunities in the first associated opportunity group may also be referred to as the existence of the first associated relationship between the multiple SRS resources.

[0262] In some implementations, the multiple sending opportunities in the first association opportunity group satisfy any of the following:

[0263] The multiple transmission opportunities in the first associated opportunity group are located in the same time slot;

[0264] A plurality of transmission opportunities in the first associated opportunity group are spaced apart by M3 time slots, where M3 is an integer.

[0265] It should be understood that if the multiple transmission opportunities in the first associated opportunity group are separated by M3 time slots, and M3=0, it means that the time slots to which the multiple transmission opportunities in the first associated opportunity group belong are adjacent.

[0266] It should be understood that if the multiple transmission opportunities in the first associated timing group are spaced apart by M3 time slots, and M3>0, it means that the multiple transmission opportunities in the first associated timing group are equally spaced, wherein the time interval between two adjacent transmission opportunities is M3 time slots.

[0267] In some implementations, the multiple transmission opportunities in the first associated opportunity group further satisfy: the multiple transmission opportunities in the first associated opportunity group are spaced apart by N3 symbols, where N3 is an integer.

[0268] It should be understood that if a plurality of transmission opportunities in the first associated opportunity group are spaced apart by N3 symbols, and N3=0, it means that the symbols occupied by the plurality of transmission opportunities in the first associated opportunity group are adjacent.

[0269] It should be understood that if the multiple transmission opportunities in the first associated timing group are spaced N3 symbols apart, and N3>0, it means that the symbols occupied by the multiple transmission opportunities in the first associated timing group are equally spaced, wherein the time interval between the symbols occupied by two adjacent transmission opportunities is N3 symbols.

[0270] It should be understood that the time relationship between the multiple sending opportunities in the first associated time group is similar to the time relationship between the first sending time and the second sending time in situation one. Based on this, the example of the time relationship between the multiple sending opportunities in situation two can refer to the example in situation one, and the embodiments of the present application will not go into details about this.

[0271] In some possible implementations, the plurality of SRS resources include at least one type of SRS resource:

[0272] Periodic SRS resources;

[0273] Semi-persistent SRS resources;

[0274] Aperiodic SRS resource.

[0275] In other words, the multiple SRS resources may include any of the following, but are not limited to:

[0276] Multiple periodic SRS resources;

[0277] Multiple semi-persistent SRS resources;

[0278] Multiple non-periodic SRS resources;

[0279] at least one periodic SRS resource and at least one semi-persistent SRS resource;

[0280] at least one periodic SRS resource and at least one aperiodic SRS resource;

[0281] at least one semi-persistent SRS resource and at least one aperiodic SRS resource;

[0282] At least one periodic SRS resource, at least one semi-persistent SRS resource, and at least one aperiodic SRS resource.

[0283] In some implementations, if the multiple SRS resources include multiple periodic SRS resources, it is agreed by default that the transmission periods of the multiple periodic SRS resources are the same.

[0284] In some implementations, if the multiple SRS resources include multiple semi-persistent SRS resources, it is agreed by default that the transmission periods of the multiple semi-persistent SRS resources are the same.

[0285] In some implementations, if the plurality of SRS resources include at least one periodic SRS resource and at least one semi-persistent SRS resource, it is agreed by default that the transmission periods of the at least one periodic SRS resource and the at least one semi-persistent SRS resource are the same.

[0286] In some implementations, when the multiple SRS resources include multiple non-periodic SRS resources, the DCIs used to trigger the multiple non-periodic SRS resources are the same or different.

[0287] In some implementations, the fact that the DCIs of multiple non-periodic SRS resources are the same may be understood as the multiple non-periodic SRS resources are triggered by the same DCI.

[0288] In some implementations, the different DCIs of the multiple non-periodic SRS resources may be understood as the DCIs of the multiple non-periodic SRS resources being triggered by multiple DCIs.

[0289] In some implementations, the different DCIs of the multiple non-periodic SRS resources may also be referred to as the DCIs of the multiple non-periodic SRS resources being not completely the same.

[0290] In some implementations, when multiple SRS resources include a non-periodic SRS resource, the reference time of the non-periodic SRS resource is any one of the following: the transmission time of the DCI used to trigger the non-periodic SRS resource; the most recent sending timing before the sending timing of the non-periodic SRS resource; the first sending timing in the first associated timing group.

[0291] In some implementations, the transmission time of the DCI may be the reception time or the sending time of the DCI.

[0292] In some possible implementations, when the reference time of the non-periodic SRS resource is the transmission time of the DCI used to trigger the non-periodic SRS resource, the reference time of the non-periodic SRS resource may be the end time or the start time of the transmission time of the DCI, that is, the first symbol or the last symbol of the PDCCH carrying the DCI, or when the PDCCH carrying the DCI occupies multiple symbols, the reference time of the non-periodic SRS resource may be one of the multiple symbols, and the embodiments of the present application do not impose any restrictions on this.

[0293] In some possible implementations, when the reference time of a non-periodic SRS resource is the most recent transmission opportunity before the transmission opportunity of the non-periodic SRS resource, the reference time of the non-periodic SRS resource may be the end time or the start time of the most recent transmission opportunity, that is, the first symbol or the last symbol of the most recent transmission opportunity, or when the most recent transmission opportunity occupies multiple symbols, the reference time of the non-periodic SRS resource may be one of the multiple symbols, and the embodiments of the present application do not impose any restrictions on this.

[0294] In some possible implementations, when the reference time of the non-periodic SRS resource is the first sending opportunity in the first associated opportunity group, the reference time of the non-periodic SRS resource can be the end time or the start time of the first sending opportunity, that is, the first symbol or the last symbol of the first sending opportunity, or when the first sending opportunity occupies multiple symbols, the reference time of the non-periodic SRS resource can be one of the multiple symbols, and the embodiments of the present application do not impose any restrictions on this.

[0295] In some implementations, the time offset of the aperiodic SRS resource relative to the reference time may be the time offset of the start time of the aperiodic SRS resource relative to the reference time, but is not limited thereto.

[0296] For example, Fig.33 A reference time diagram provided in an embodiment of the present application, such as Fig.33 As shown, the reference time of the non-periodic SRS resource is the transmission time of the DCI used to trigger the non-periodic SRS resource, wherein the reference time of the non-periodic SRS resource can specifically be the end time of the transmission time of the DCI, and the time slot offset X of the non-periodic SRS resource relative to the reference time is the time slot offset of the start time of the non-periodic SRS resource relative to the reference time.

[0297] For example, Fig.34 Another reference time schematic diagram provided in the embodiment of the present application is as follows: Fig.34 As shown, the reference time of the non-periodic SRS resource is the most recent transmission opportunity before the transmission opportunity of the non-periodic SRS resource, wherein the reference time of the non-periodic SRS resource can specifically be the end time of the most recent transmission opportunity, and the time slot offset X of the non-periodic SRS resource relative to the reference time is the time slot offset of the start time of the non-periodic SRS resource relative to the reference time.

[0298] For example, Fig.35 Another reference time diagram provided in the embodiment of the present application is as follows: Fig.35 As shown, the reference time of the non-periodic SRS resource is the first sending opportunity in the first associated opportunity group, wherein the reference time of the non-periodic SRS resource can specifically be the end time of the first sending opportunity, and the time slot offset X of the non-periodic SRS resource relative to the reference time is the time slot offset of the start time of the non-periodic SRS resource relative to the reference time.

[0299] In some implementations, when the plurality of SRS resources include a plurality of aperiodic SRS resources, time offsets of the plurality of aperiodic SRS resources relative to corresponding reference times are configured individually or jointly.

[0300] For example, assuming that the first associated timing group includes: two non-periodic SRS resources, the network device can configure the time slot offsets of the two non-periodic SRS resources relative to the reference time through an RRC signaling. For example, the RRC signaling includes: the time slot offsets of the two non-periodic SRS resources relative to the reference time are 1 time slot and 2 time slots respectively.

[0301] For example, assuming that the first associated timing group includes: two non-periodic SRS resources, the network device can respectively configure the time offsets of the two non-periodic SRS resources relative to the reference time through two RRC signalings, for example, wherein one RRC signaling includes: the time offset of a certain non-periodic SRS resource relative to the reference time is 1 time slot; the other RRC signaling includes: the time offset of another non-periodic SRS resource relative to the reference time is 2 time slots.

[0302] In some implementations, at least one of the following parameters of the multiple SRS resources is the same: frequency domain resources; cyclic shift; number of antenna ports; number of repetitions; sequence identifier; number of occupied symbols; sequence hopping parameter; sequence group hopping parameter; transmit power; spatial relationship information; associated channel state information measurement reference signal (Channel State Information Reference Signal, CSI-RS); associated phase tracking reference signal (Phase Tracking Reference Signal, PTRS).

[0303] In some implementations, the plurality of SRS resources are associated via third signaling.

[0304] In some implementations, the third signaling may be RRC signaling for enabling a channel prediction function.

[0305] In some implementations, the third signaling may be associated signaling of SRS resources used for channel prediction.

[0306] In some implementations, when the multiple SRS resources belong to the same SRS resource set, the third signaling may be an instruction for indicating the resource set.

[0307] In some implementations, when the multiple SRS resources belong to the same resource list, the third signaling may be an instruction for indicating the resource list.

[0308] It should be understood that the embodiment of the present application does not limit the third signaling.

[0309] The following describes the first and second situations of the first association timing group:

[0310] In some implementations, in the case where a plurality of transmission opportunities in the first associated timing group correspond to one SRS resource, the transmission of the SRS resource maintains phase continuity over the plurality of transmission opportunities in the first associated timing group.

[0311] In some implementations, when multiple transmission opportunities in the first associated timing group correspond to multiple SRS resources, the transmission of the multiple SRS resources maintains phase continuity over the multiple transmission opportunities in the first associated timing group.

[0312] The reason for ensuring that the transmission of one or more SRS resources corresponding to multiple transmission opportunities maintains phase continuity is to facilitate combining multiple transmission opportunities in the first associated opportunity group to perform channel prediction based on channel estimation results at multiple transmission opportunities.

[0313] In some implementations, the terminal device does not receive a downlink signal between multiple transmission opportunities in the first associated timing group or in a first time window; wherein the first time window covers part or all of the multiple transmission opportunities in the first associated timing group.

[0314] In some implementations, the first time window is determined by the terminal capability. For example, the length of the first time window supported by the terminal device 1 is 28 symbols.

[0315] In some possible implementations, the first time window may be configured by the network device through a fourth signaling, or may be a default agreement between the terminal device and the network device, or may be negotiated between the terminal device and the network device, and the embodiments of the present application do not impose any restrictions on this.

[0316] In some implementations, the fourth signaling may be RRC signaling or the like.

[0317] The second association timing group will be described below:

[0318] In some implementations, the second associated opportunity group includes L1 third sending opportunities, where L1 is a positive integer greater than 1; wherein the L1 third sending opportunities are sending opportunities in periodic sending opportunities or semi-persistent sending opportunities.

[0319] In some implementations, the value of L1 may be configured through RRC signaling, but is not limited thereto.

[0320] It should be understood that the above-mentioned P sending opportunities may include one or more second associated opportunity groups.

[0321] For example, Fig.36 A schematic diagram of a second association timing group provided in an embodiment of the present application is shown in FIG. Fig.36As shown, every two transmission opportunities in the periodic SRS resources constitute a second associated opportunity group.

[0322] For example, Fig.37 A schematic diagram of another second association timing group provided in an embodiment of the present application, such as Fig.37 As shown, two sending opportunities in the periodic SRS resources constitute a second associated opportunity group.

[0323] In some possible implementations, if P associated opportunities include: a first associated opportunity group and a second associated opportunity group, and multiple sending opportunities in the first associated opportunity group correspond to one SRS resource, the multiple sending opportunities in the first associated opportunity group include: a first sending opportunity and at least one second sending opportunity, the multiple sending opportunities in the second associated opportunity group correspond to one SRS resource, and the second associated opportunity group includes L1 third sending opportunities, then the SRS resources corresponding to the first associated opportunity group and the second associated opportunity group are the same, and the third sending opportunity here is the first sending opportunity.

[0324] For example, Fig.38 A schematic diagram of a first association timing group and a second association timing group provided in an embodiment of the present application is shown in FIG. Fig.38 As shown, it includes: a periodic SRS resource, the sending opportunity corresponding to the periodic SRS resource can be called a first sending opportunity, a second sending opportunity can be inserted on the basis of the first sending opportunity, the second sending opportunity and the first sending opportunity correspond to the same SRS resource, one first sending opportunity and the second sending opportunity can form a first associated opportunity group, and three first sending opportunities form a second associated opportunity group.

[0325] In some implementations, if the P association opportunities include: a first association opportunity group and a second association opportunity group, the first association opportunity group and the second association opportunity group can be jointly used for channel prediction. Fig.38 As shown, the first sending opportunity and the second sending opportunity in the first associated opportunity group correspond to a channel estimation result respectively, and in the second associated opportunity group, except for the first first sending opportunity, the other two first sending opportunities also correspond to a channel estimation result respectively, and joint channel prediction can be performed based on the channel estimation results on these sending opportunities.

[0326] In some implementations, the second associated timing group includes L2 fourth sending opportunities, where L2 is a positive integer greater than 1; wherein the L2 fourth sending opportunities are L2 sending opportunities corresponding to one SRS resource among multiple SRS resources.

[0327] In some implementations, the value of L2 may be configured through RRC signaling, but is not limited thereto.

[0328] In some implementations, each of the multiple SRS resources may correspond to one or more second associated opportunity groups.

[0329] In some implementations, at least one SRS resource among the multiple SRS resources may correspond to one or more second associated opportunity groups.

[0330] In some possible implementations, if P associated opportunities include: a first associated opportunity group and a second associated opportunity group, and multiple sending opportunities in the first associated opportunity group correspond to multiple SRS resources, multiple sending opportunities in the second associated opportunity group correspond to one SRS resource, and the second associated opportunity group includes L2 fourth sending opportunities, then one of the SRS resources corresponding to the second associated opportunity group is one SRS resource among the multiple SRS resources corresponding to the first associated opportunity group, and the fourth sending opportunity is also the sending opportunity of the one SRS resource.

[0331] For example, Fig.39 A schematic diagram of another first association timing group and a second association timing group provided in an embodiment of the present application is shown in FIG. Fig.39 As shown, it includes: two SRS resources, wherein one SRS resource is a periodic SRS resource, and the other SRS resource is a non-periodic SRS resource, the sending timing corresponding to the non-periodic SRS resource and its previous most recent sending timing form a first associated timing group, and the three sending timings in the periodic SRS resource form a second associated timing group.

[0332] In some implementations, if the P association opportunities include: a first association opportunity group and a second association opportunity group, the first association opportunity group and the second association opportunity group can be jointly used for channel prediction. Fig.39 As shown, each transmission opportunity in the first associated opportunity group and the second associated opportunity group corresponds to a channel estimation result, and joint channel prediction can be performed based on these four channel estimation results.

[0333] In some possible implementations, the joint channel prediction may be performed by a terminal device or a network device, which is not limited in the embodiments of the present application.

[0334] In some implementations, one SRS resource corresponding to multiple transmission opportunities in the second associated opportunity group maintains phase continuity across the multiple transmission opportunities in the second associated opportunity group.

[0335] The reason for ensuring that the transmission of one SRS resource corresponding to multiple transmission opportunities maintains phase continuity is to facilitate combining multiple transmission opportunities in the second associated opportunity group to perform channel prediction based on channel estimation results on multiple transmission opportunities.

[0336] In some implementations, the terminal device does not receive a downlink signal between multiple transmission opportunities in the second associated opportunity group or in a second time window; wherein the second time window covers part or all of the multiple transmission opportunities in the second associated opportunity group.

[0337] In some implementations, the second time window is determined by the terminal capability. For example, the length of the second time window supported by the terminal device 1 is 140 symbols.

[0338] In some possible implementations, the second time window may be configured by the network device through the fifth signaling, or may be a default agreement between the terminal device and the network device, or may be negotiated between the terminal device and the network device, and the embodiments of the present application do not impose any restrictions on this.

[0339] In some implementations, the fifth signaling may be RRC signaling or the like.

[0340] In an embodiment of the present application, a terminal device can send one or more SRS resources at multiple sending times, some or all of which are associated with each other, and the associated sending times can be used jointly for channel prediction, and then the precoding calculation of subsequent downlink transmission is performed based on the channel prediction result. Since the channel prediction is a prediction of the wireless channel in the subsequent time, even if the wireless channel changes rapidly, the precoding of the downlink transmission based on the channel prediction result will be more matched with the wireless channel at the subsequent PDSCH transmission time, thereby improving the transmission performance of the PDSCH. Among them, the more sending times are jointly predicted, the more accurate the channel prediction result, and thus the higher the matching degree between the precoding of the downlink transmission and the PDSCH, thereby making the transmission performance of the PDSCH better.
