[0004] Sounding Reference Signals (SRS) are important reference signals in communication systems and are widely used in various functions within them. For example, SRS can be used for non-codebook transmission. Network devices can configure a non-codebook-based Physical Downlink Shared Channel (PDSCH) transmission mode. In this mode, network devices perform uplink channel estimation based on the SRS sent by terminal devices and determine downlink transmission precoding based on channel reciprocity.

[0005] 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.

[0085] 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.

[0086] 1. Introduction to SRS Resources

[0087] In NR systems, SRS can be used for beam management, codebook-based transmission, non-codebook-based transmission, and antenna switching. Network equipment can configure one or more SRS resource sets (SRS Resource Sets) to terminal devices through high-layer signaling. Each SRS resource set can include one or more SRS resources. The configuration of each SRS resource set includes: the purpose of the SRS resource set, periodicity characteristics (periodic, semi-persistent, or aperiodic), and other configurations.

[0088] 2. Time Domain Resources and Antenna Ports of SRS Resources

[0089] In NR Release-15 or 16, within a time slot, the SRS resource can occupy the last 6 symbols. The number of SRS symbols Ns configurable by higher-layer signaling is {1, 2, 4}, and the comb-2 and comb-4 structures in the frequency domain are supported, with the supported repetition counts R being {1, 2, 4}. In Release-17, within a time slot, the symbol starting position of the SRS resource can be at any symbol within the time slot. The number of SRS symbols Ns has been increased to {1, 2, 4, 8, 10, 12, 14}, and the comb-8 structure is also supported. In addition, the supported repetition counts R has also been increased to {1, 2, 4, 5, 6, 7, 8, 10, 12, 14}.

[0090] Currently, each SRS resource can have 1, 2, or 4 antenna ports. Each antenna port occupies the same SRS resource. The SRSs of multiple terminal devices can be time division multiplexed (TDM) or frequency division multiplexed (FDM) in a time slot using a comb structure.

[0091] 3. SRS Sequence

[0092] The base sequence for the SRS resource is a ZC (Zadoff-Chu) sequence, which is distinguished by its orthogonality. The concept of cyclic shift (CS) is introduced during SRS sequence generation. For the combo-2 structure, the maximum number of cyclic shifts is defined as 8; for the combo-4 structure, the maximum number of cyclic shifts is defined as 12; and for the combo-8 structure, the maximum number of cyclic shifts is defined as 6.

[0093] According to the TS38.211 protocol, the antenna port p i The SRS sequence sent is as follows:

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

[0095] is the SRS sequence, which is generated based on the 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 cyclic shift of ;

[0099] The SRS sequence is divided into 30 sequence groups, each of which contains two sequences. u is the index or identifier of the sequence group, and its value ranges from 0 to 29. v is the index or identifier of the two sequences in the sequence group, and its value ranges from 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 aperiodic. Based on this, SRS resources are divided into: periodic SRS resources, semi-persistent SRS resources, and aperiodic SRS resources.

[0102] Periodic SRS resources refer to SRS resources that are periodically transmitted. 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. Their period and slot offset are configured via RRC signaling, but their activation and deactivation signaling is carried by the Media Access Layer Control Element (MAC CE). Upon receiving activation signaling, a terminal device begins transmitting SRS until receiving deactivation signaling. Spatial relationship information for semi-persistent SRS can be carried along with the MAC CE that activates SRS.

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

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

[0108] After receiving a DCI triggering an aperiodic SRS resource, the terminal device transmits an SRS on the SRS resource group indicated by the DCI. The slot offset between the DCI and the aperiodic SRS resource can be configured by higher-layer signaling, such as RRC signaling. Furthermore, for an aperiodic SRS resource, the terminal device can also determine the transmit beam used to transmit the SRS on the resource based on 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 resource 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 larger change than 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, and 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] 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 all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0112] FIG2 is an interactive flow chart of a method for transmitting a sounding reference signal according to an embodiment of the present application. The method may be executed by a terminal device or a network device. As shown in FIG2 , 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 between the 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 between the 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, the multiple transmission opportunities in the first associated opportunity group correspond to different SRS resources, that is, different SRS resources are transmitted on the multiple transmission opportunities in the first associated opportunity group.

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

[0124] In some implementations, when the plurality of transmission opportunities in the first associated opportunity group correspond to one SRS resource, the plurality of 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] Non-periodic 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; and the non-periodic sending opportunity refers to the sending opportunity that occurs based on DCI triggering.

[0134] In some 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 of the multiple second sending opportunities, the second sending opportunity can 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] Non-periodic sending timing.

[0139] In some implementations, if the first sending opportunity is a sending opportunity among the periodic sending opportunities or a sending opportunity among the semi-continuous sending opportunities, and the second sending opportunity is a sending opportunity among the periodic sending opportunities or a sending opportunity among the 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 above the basic transmission opportunity. The basic transmission opportunity refers to the transmission opportunity of the SRS resource determined based on the occupied symbol position of the SRS resource and the RRC parameter SRS-PeriodicityAndOffset.

[0141] In some implementations, the second transmission opportunity is associated with the first transmission opportunity by default, i.e., a first association. It can also be understood that the default agreement uses the first transmission opportunity and the second transmission opportunity together for 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 is a schematic diagram of a first associated timing group provided in an embodiment of the present application. As shown in Figure 3, the first sending timing is a sending timing in the periodic sending timing, the second sending timing is a non-periodic sending timing, and the first associated timing group includes: a second sending timing and the first sending timing most recently before the second sending timing.

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

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

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

[0147] It should be understood that each of the first association opportunity groups shown in FIG3 to FIG6 includes one second sending opportunity. In fact, the first association opportunity group may include multiple second sending opportunities. This situation will be exemplified below with an example:

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

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

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

[0151] For example, Figure 10 is a schematic diagram of another first associated timing group provided in an embodiment of the present application. As shown in Figure 10, 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 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 associated opportunity group includes multiple second transmission opportunities, the types of the multiple second transmission opportunities can be the same. For example, in each of the examples shown in Figures 6 to 10, the two second transmission opportunities are of the same type. For example, they can be either periodic transmission opportunities or aperiodic transmission opportunities. Of course, the types of the multiple second transmission opportunities can also be different.

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

[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 opportunity 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 opportunity 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 go into details about this.

[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 transmission opportunity is separated from the first transmission opportunity by M1 time slots, where M1 is an integer.

[0159] For example, Figure 12 is a schematic diagram of a time domain relationship provided in an embodiment of the present application. As shown in Figure 12, the first sending opportunity and the second sending opportunity are located in the same time slot.

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

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

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

[0163] For example, FIG14 is another schematic diagram of a time domain relationship provided in an embodiment of the present application. As shown in FIG14 , the time slot to which the first sending opportunity belongs is adjacent to the time slot to which the second sending opportunity belongs.

[0164] For example, FIG15 is another schematic diagram of a time domain relationship provided in an embodiment of the present application. As shown in FIG15 , the time slot to which the first sending opportunity belongs and the time slot to which the second sending opportunity belongs are separated by one time slot, that is, M1=1 as mentioned above.

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

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

[0167] For example, Figure 17 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 17, there are two second sending opportunities, and the time slot to which the first sending opportunity belongs and the time slot to which the first second sending opportunity belongs are separated by 1 time slot, that is, the above-mentioned M1=1.

[0168] In some implementations, when the first transmission opportunity is one of the periodic transmission opportunities or one of 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 spaced N1 symbols apart from the first transmission opportunity, where N1 is an integer.

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

[0176] For example, FIG18 is another schematic diagram of a time domain relationship provided in an embodiment of the present application. As shown in FIG18 , the occupied symbol of the first sending opportunity and the occupied symbol of the second sending opportunity are adjacent.

[0177] For example, FIG19 is another schematic diagram of a time domain relationship provided in an embodiment of the present application. As shown in FIG19 , the occupied symbol of the first sending opportunity and the occupied symbol of the second sending opportunity are separated by one symbol.

[0178] In some implementations, when the first associated opportunity group includes multiple second transmission opportunities, the multiple second transmission opportunities are N1 symbols apart from the first transmission opportunity, which means that the first second transmission opportunity in the multiple second transmission opportunities is N1 symbols apart from the first transmission opportunity.

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

[0180] For example, Figure 21 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 21, there are two second sending opportunities, and the symbol occupied by the first sending opportunity and the symbol occupied by the first second sending opportunity are separated by 1 symbol, that is, the above-mentioned N1=1.

[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 multiple second transmission opportunities belong to the same time slot;

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

[0184] For example, as shown in FIG13 , a plurality of second transmission opportunities belong to the same time slot.

[0185] It should be understood that the first sending opportunity and the two second sending opportunities in Figure 13 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, Figure 22 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 22, there are two second sending opportunities, and the time slots to which the two second sending opportunities belong are adjacent.

[0188] For example, Figure 23 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 23, 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, the time interval between the first transmission opportunity and the first of the multiple second transmission opportunities is the same as the time interval between the multiple second transmission opportunities. This facilitates the implementation of the channel prediction algorithm, including improving channel prediction performance or reducing channel prediction complexity.

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

[0193] For example, Figure 25 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 25, there are two second sending opportunities, and the symbols occupied by the two second sending opportunities are adjacent.

[0194] For example, Figure 26 is another time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 26, there are two second sending opportunities, and the symbol interval between the two second sending opportunities is 1 symbol.

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

[0196] For example, Figure 27 is another time domain relationship diagram provided by an embodiment of the present application. As shown in Figure 27, there are two second sending opportunities, the interval between the first sending opportunity and the first second sending opportunity is 1 symbol, and the interval between the two second sending 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 immediately before it and a time interval between the second transmission opportunity and the first transmission opportunity immediately after it may be the same.

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

[0199] For example, Figure 28 is a time domain relationship diagram provided in an embodiment of the present application. As shown in Figure 28, 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 nearest first sending timing belongs is also 1 time slot.

[0200] For example, Figure 29 is another time domain relationship diagram provided by an embodiment of the present application. As shown in Figure 29, 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 time relationship between the first sending opportunity and the second sending opportunity and between the multiple second sending opportunities satisfies the above time relationship 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 opportunity group includes: a first transmission opportunity and a second transmission opportunity, wherein the number of occupied symbols of the first transmission opportunity and the second transmission opportunity are both 4.

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

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

[0208] In some implementations, for any second transmission opportunity in the first associated timing 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., and this embodiment of the present application does not limit this.

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

[0211] In some implementations, for any second transmission opportunity in the first associated opportunity group, if 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 specifies 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 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, if 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 specifies that the number of occupied symbols of the second transmission opportunity is the same as the number of occupied symbols of the first transmission opportunity.

[0214] In some implementations, for any second transmission opportunity in the first associated opportunity group, when the second transmission opportunity is a non-periodic transmission opportunity, the second transmission 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 these multiple symbols. 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, Figure 30 is a reference time schematic diagram provided in an embodiment of the present application. As shown in Figure 30, 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 contains multiple symbols, the reference time of the second sending opportunity may be one of these multiple symbols. The embodiments of the present application do not limit 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, Figure 31 is another reference time schematic diagram provided in an embodiment of the present application. As shown in Figure 31, the reference time of the second sending opportunity is the end time of the first sending opportunity, 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.

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

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

[0225] For example, it is assumed that the first associated opportunity group includes two aperiodic second transmission opportunities, and the two aperiodic second transmission opportunities 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 aperiodic transmission opportunities may also be referred to as the DCIs of the multiple aperiodic transmission opportunities being not completely the same.

[0228] For example, it is assumed that the first associated opportunity group includes: two aperiodic second transmission opportunities, wherein one aperiodic second transmission opportunity is triggered by DCI 1, and the other aperiodic second transmission opportunity is triggered by DCI 2.

[0229] For example, it is assumed that the first associated opportunity group includes: three aperiodic second transmission opportunities, wherein one aperiodic second transmission opportunity is triggered by DCI 1, and the other two aperiodic second transmission opportunities are triggered by DCI 2.

[0230] In some implementations, time offsets of the multiple 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 offset of these 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 these 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 configure the time slot offsets of these 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, by determining the first transmission timing by the occupied symbol position of the SRS resource and the RRC parameter SRS-PeriodicityAndOffset, but the present invention 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., and this embodiment of the present application does not limit this.

[0236] In some implementations, if the second transmission opportunity is one of the periodic transmission opportunities, the second signaling may be 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 can also 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 may 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 an aperiodic transmission opportunity, the second signaling may be RRC signaling for configuring the aperiodic transmission opportunity. For example, the RRC signaling may be used to configure a 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.

[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 transmission opportunity is a non-periodic transmission opportunity and the first transmission opportunity is a transmission opportunity in the periodic transmission opportunity, the second signaling may be used to indicate a time offset of the second transmission opportunity relative to the first transmission 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 transmission opportunity is a non-periodic transmission opportunity and the first transmission opportunity is a periodic transmission opportunity, the default rule may specify a time offset of the second transmission opportunity relative to the first transmission 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 transmission opportunity is a non-periodic transmission opportunity and the first transmission opportunity is also a non-periodic transmission opportunity, the default rule may specify a time offset of the second transmission opportunity relative to the first transmission 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, then 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 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.

[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 opportunity group includes multiple second transmission opportunities, the multiple second transmission opportunities can be determined by the same second signaling or by different second signaling, and the second signaling can be RRC signaling.

[0255] For example, if the first associated opportunity group includes two second transmission opportunities, and both second transmission opportunities are non-periodic transmission opportunities, a second signaling is used to indicate that the time offset of the two second transmission opportunities 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 both are equal to the time offset.

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

[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, Figure 32 is a schematic diagram of the relationship between the sending timing and SRS resources provided in an embodiment of the present application. As shown in Figure 32, it includes two SRS resources, namely: SRS resource 1 and SRS resource 2, and SRS resource 1 is a periodic SRS resource, and SRS resource 2 is a non-periodic SRS resource. 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 a first association relationship between the multiple transmission opportunities in the first associated opportunity group may also be referred to as the existence of a first association relationship between multiple SRS resources.

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

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

[0264] The multiple 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 opportunity group are spaced apart by M3 time slots, and M3>0, it means that the multiple transmission opportunities in the first associated opportunity 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 the multiple transmission opportunities in the first associated opportunity group are separated by N3 symbols, and N3=0, it means that the symbols occupied by the multiple 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 opportunity group are spaced N3 symbols apart, and N3>0, it means that the symbols occupied by the multiple transmission opportunities in the first associated opportunity 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 timing group is similar to the time relationship between the first sending opportunity 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 implementations, the plurality of SRS resources include at least one of the following types of SRS resources:

[0272] Periodic SRS resources;

[0273] Semi-persistent SRS resources;

[0274] Aperiodic SRS resources.

[0275] In other words, 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 aperiodic 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 multiple 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 aperiodic SRS resources, the DCIs used to trigger the multiple aperiodic SRS resources are the same or different.

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

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

[0289] In some implementations, the different DCIs of the multiple aperiodic SRS resources may also be referred to as the DCIs of the multiple aperiodic 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 can 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 can be one of these multiple symbols. The embodiments of the present application do not impose any restrictions on this.

[0293] In some possible implementations, when 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, the reference time of the non-periodic SRS resource can 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 can be one of these multiple symbols. 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 these multiple symbols. 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, Figure 33 is a reference time schematic diagram provided in an embodiment of the present application. As shown in Figure 33, 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, Figure 34 is another reference time schematic diagram provided by an embodiment of the present application. As shown in Figure 34, the reference time of the non-periodic SRS resource is the most recent sending opportunity before the sending opportunity of the non-periodic SRS resource, wherein the reference time of the non-periodic SRS resource can specifically be the end moment of the most recent 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 starting moment of the non-periodic SRS resource relative to the reference time.

[0298] For example, Figure 35 is another reference time schematic diagram provided by an embodiment of the present application. As shown in Figure 35, 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 these 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 these 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 configure the time offset of these 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 (CSI-RS); associated phase tracking reference signal (PTRS).

[0303] In some implementations, the multiple 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 embodiments of the present application do not limit the third signaling.

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

[0310] In some implementations, when multiple transmission opportunities in the first associated opportunity group correspond to one SRS resource, the transmission of the SRS resource maintains phase continuity across the multiple transmission opportunities in the first associated opportunity group.

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

[0313] In some implementations, the terminal device does not receive downlink signals between multiple transmission opportunities in the first associated opportunity 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 opportunity 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 can be configured by the network device through the fourth signaling, or can be a default agreement between the terminal device and the network device, or can be negotiated between the terminal device and the network device. The embodiments of the present application do not limit this.

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

[0317] The second association timing group is described below:

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

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

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

[0323] In some 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, Figure 38 is a schematic diagram of a first associated timing group and a second associated timing group provided in an embodiment of the present application. As shown in Figure 38, it includes: a periodic SRS resource, the sending timing corresponding to the periodic SRS resource can be called a first sending timing, and a second sending timing can be inserted on the basis of the first sending timing. The second sending timing corresponds to the same SRS resource as the first sending timing, and one first sending timing and the second sending timing can form a first associated timing group, and three first sending timings form a second associated timing 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. For example, as shown in FIG38 , the first transmission opportunity and the second transmission opportunity in the first association opportunity group each correspond to a channel estimation result, and in the second association opportunity group, except for the first first transmission opportunity, the remaining two first transmission opportunities also each correspond to a channel estimation result. Joint channel prediction can be performed based on the channel estimation results for these transmission opportunities.

[0326] In some implementations, the second associated opportunity 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, Figure 39 is a schematic diagram of another first associated timing group and a second associated timing group provided in an embodiment of the present application. As shown in Figure 39, 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 the most recent sending timing before it constitute 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. For example, as shown in FIG39 , each transmission opportunity in the first association opportunity group and the second association 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 implementations, the joint channel prediction may be performed by a terminal device or a network device, and the embodiments of the present application do not impose any restrictions on this.

[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 the multiple transmission opportunities.

[0336] In some implementations, the terminal device does not receive downlink signals 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 can be configured by the network device through the fifth signaling, or can be a default agreement between the terminal device and the network device, or can be negotiated between the terminal device and the network device. The embodiments of the present application do not limit this.

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

[0340] In an embodiment of the present application, a terminal device can send one or more SRS resources at multiple transmission opportunities, and some or all of these transmission opportunities are associated with each other, and the transmission opportunities with an associated relationship can be jointly used for channel prediction, and then the precoding calculation of the 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 moment, thereby improving the transmission performance of the PDSCH. Among them, the more transmission opportunities are jointly predicted, the more accurate the channel prediction result, and thus the higher the matching degree between the downlink transmission precoding and the PDSCH, thereby making the transmission performance of the PDSCH better.
