Background

The third generation partnership project (3rd generation partnership project,3GPP) is dedicated to the establishment of standards for communication protocols. Among them, the existing communication protocol standard has been described with respect to sounding reference signals (sounding reference signal, SRS) in the communication process.

Currently, frequency hopping techniques (FHSS) supported by New Radio (NR) systems require SRS to be transmitted over the entire frequency band resource. Meanwhile, in an actual communication network, since a part of the entire frequency band resources are subject to severe interference of other wireless systems (such as a video backhaul system), the part of the frequency band resources cannot be subjected to data scheduling, so that SRS is not required to be transmitted on the frequency domain of the part of the frequency band. Or, in case of high correlation in the frequency domain, since the channel has high correlation in the entire frequency band resource, the SRS is transmitted only on a part of the frequency band resource of the entire frequency band resource. It can be seen that, based on the existing communication protocol standard, further research on the frequency band resources used for transmitting SRS is required, so as to improve the utilization efficiency of the frequency band resources, and improve the multiplexing capability of SRS.

Before describing the sounding reference signal configuration method provided in this embodiment in detail, the related communication technology according to this embodiment will be described.

1. Sounding reference signals (sounding reference signal, SRS)

SRS is an important reference signal in 5G/NR systems and is widely used in various functions in NR systems, for example:

(1) A terminal probing procedure for channel state information (channel state information, CSI) acquisition of the downlink;

(2) For upstream beam management;

(3) For a positioning function;

(4) In conjunction with codebook-based uplink transmission, such as frequency domain scheduling and Rank/precoding matrix indication (precoding matrix indicator, PMI)/modulation coding scheme (modulation coding scheme, MCS) determination;

(5) In conjunction with non-codebook based uplink transmissions, such as frequency domain scheduling and SRS resource indication (sounding reference signal resource indicator, SRI)/MCS determination.

The NR SRS introduces the SRS resource (SRS resource) concept as well as the SRS resource set (SRS resource set) concept. Wherein the network device may configure one or more for one terminal, and each SRS Resource set may configure one or more SRS resources.

In addition, SRS supports three different transmission modes: periodic (periodic), semi-persistent (semi-persistent), and aperiodic (periodic). The method comprises the following steps:

(1) Periodic SRS and semi-persistent SRS

The periodic SRS refers to a periodically transmitted SRS, the period and slot offset (slot offset) of which are configured by RRC signaling. If the terminal receives the relevant configuration information configured by the RRC signaling, the terminal transmits SRS in a certain period according to the relevant information until the relevant configuration information fails. Furthermore, spatial correlation information (spatial relation information) of the periodic SRS is also signaled by RRC. Wherein the spatial correlation information is used to implicitly indicate the transmitted beam, and the spatial correlation information may indicate a channel state information reference signal (channel state information, CSI-RS), a synchronization signal block (synchronization signal and PBCH block, SSB), or a reference SRS. Accordingly, the terminal may determine a transmission beam of the SRS resource according to the reception beam of the CSI-RS/SSB indicated by the spatial correlation information or determine a transmission beam of the SRS resource according to the transmission beam of the reference SRS resource.

Semi-persistent SRS is also referred to as periodically transmitted SRS, whose period and slot offset are configured by RRC signaling, but whose activation signaling and deactivation signaling are carried by a control unit (media access control control element, MAC CE) of the medium access control layer. The terminal starts to periodically transmit SRS after receiving the activation signaling until receiving the deactivation signaling. Meanwhile, the spatial related information of the semi-persistent SRS is carried together through the MAC CE that activates the SRS.

After receiving the period and the time slot offset of the RRC signaling configuration, the terminal determines the time slot capable of being used for transmitting the SRS according to the following formula:

wherein,

indicating the number of slots, n, contained in each radio frame _f A radio frame number is indicated and,

represents a time slot number, T _offset Representing slot offset, T, configured by RRC signaling _SRS A period configured by RRC signaling is represented.

(2) Aperiodic SRS

Aperiodic SRS refers to an aperiodic transmitted SRS. Among them, aperiodic SRS is a newly introduced concept in the NR system. Meanwhile, the network device may trigger the terminal to aperiodically transmit SRS through downlink control information (downlink control information, DCI). In addition, the trigger signaling for triggering the aperiodic SRS transmission may be carried by DCI bearers for scheduling a physical uplink shared channel (physical uplink shared channel, PUSCH) or a physical downlink shared channel (physical downlink shared channel, PDSCH) in the UE-specific search space or by DCI format 2_3 (DCI format 2_3) in the common search space. The DCI format 2_3 may be used not only to trigger aperiodic SRS transmission but also to configure TPC commands for SRS on a group of UEs or a group of carriers at the same time. Meanwhile, the DCI carries a 2-bit SRS-request to trigger aperiodic transmission of SRS.

And after receiving the aperiodic SRS trigger signaling (such as DCI), the terminal performs aperiodic SRS transmission on the SRS resource set indicated by the trigger signaling. Wherein the slot offset between the trigger signaling and the aperiodic SRS transmission is configured by higher layer signaling (e.g., RRC signaling). Meanwhile, the network equipment indicates configuration parameters of each SRS resource set of the terminal in advance through high-layer signaling, wherein the configuration parameters comprise time-frequency resources, sequence parameters, power control parameters and the like. In addition, for each SRS resource in the triggered SRS resource set, the terminal may also determine a transmission beam used for transmitting the SRS on the SRS resource through spatial related information of the SRS resource, where the spatial related information is configured to each SRS resource through RRC information.

Note that symbol C shown in the frequency domain configuration table 1 of SRS _SRS And symbol B _SRS Determining m _SRS,b The number of physical resource blocks (physical resource block, PRBs) for SRS transmission is represented. Wherein b=b _SRS ，C _SRS E {0,1,., 63} is given by the domain (field) c-SRS contained in the higher layer parameter freqhoping, B _SRS E {0,1,2,3} is given by the domain b-SRS contained in the higher layer parameter freqhoping.

NR system supporting SRS, if meeting b _hop <B _SRS In the case (wherein b _hop Parameters configured for RRC signaling), the terminal transmits the SRS signal in the form of frequency hopping. Wherein m is _SRS,0 Representing the total bandwidth of SRS hopping, m _SRS,b The number of PRBs per hop transmission is indicated. Further, the terminal determines the frequency domain position of each hop by the following formula:

wherein N is _b Determined by a preset table, n _RRC Parameters configured for RRC signaling, operators

Representing a downward rounding, F _b (n _SRS ) Is determined by the following formula:

wherein, no matter N _b Is used for the number of the values of (a),

wherein,

represents the number of consecutive OFDM symbols (configured by RRC signaling), R is a repetition factor (configured by RRC signaling), and R is used to indicate the number of repeated OFDM symbols without frequency hopping. For example, when r=1, frequency hopping is performed in units of 1 OFDM symbol; when r=2, frequency hopping is performed in units of 2 OFDM symbols.

TABLE 2

In conjunction with the above description, the embodiment of the present application provides a flowchart of a sounding reference signal configuration method, please refer to fig. 2. The method comprises the following steps:

and S210, the network equipment sends first information to the terminal.

Wherein the first information may be used to indicate a resource configuration of the sounding reference signal.

Specifically, the network device may send first information for the sounding reference signal resource to the terminal.

It should be noted that, the existing communication protocol standard provides relevant regulations for sounding reference signal resources configured by the network device to the terminal, and at this time, the terminal needs to transmit several SRSs on the configured sounding reference signal resources. However, in the embodiment of the present application, first information for the sounding reference signal resource is sent to the terminal through the network device; then, the terminal determines a resource location distribution for transmitting the SRS within the sounding reference signal resource according to the first information, and transmits the SRS through the resource location distribution. In contrast to several SRS transmissions specified in the existing communication protocol standard, the embodiments of the present application only need to transmit SRS on all or part of the frequency band resources of the sounding reference signal resource through the resource location distribution, i.e. all or part of SRS is transmitted. Meanwhile, transmitting part of SRS has two main benefits: the first is to increase the power density, that is, the transmission part SRS can obtain additional power gain; the second is to improve multiplexing capability of SRS, that is, no frequency band resource for transmitting SRS can be configured to other terminals.

The embodiments of the present application will specifically describe sounding reference signal resources.

Specifically, the sounding reference signal resource (SRS resource) in the embodiment of the present application is a sounding reference signal resource in the sounding reference signal resource set (SRS resource set). Meanwhile, the sounding reference signal resource set is configured by the network device through RRC signaling. It should be noted that, the network device may configure at least one set of sounding reference signal resources to the terminal through RRC signaling, and each set of sounding reference signal resources includes at least one sounding reference signal resource.

Further, the set of sounding reference signal resources is configured by the higher layer parameter SRS-Resource, and the sounding reference signal resources are configured by the higher layer parameter SRS-Resource. Note that the information elements (information element, IE) in RRC signaling include SRS-Config information elements, which are used to configure transmission of sounding reference signals. Meanwhile, the SRS-Config information element contains a higher-layer parameter SRS-Resource set and a higher-layer parameter SRS-Resource.

Further, the higher-layer parameter SRS-resource contains a use (use) parameter, and the use may be configured as one of the sets { beam management, codebook, non-codebook, antenna switching }.

Further, the higher layer parameters SRS-Resource include a frequency hopping (freqhoping) parameter, and freqhoping includes the following three fields: c-SRS, b-hop. Wherein, the c-SRS may be configured to take one value in the set (0, …, 63); b-SRS may be configured to take one value in the set (0, …, 3) and b-hop may be configured to take one value in the set (0, …, 3).

Further, the higher layer parameters SRS-Resource may include a second parameter, and the second parameter may include the following three fields: start position (startPosition), number of consecutive OFDM symbols (nrofSymbols), repetition factor (repetition factor). Wherein the second parameter may be used to indicate resource mapping information.

Further, the second parameter may be a resource mapping parameter (resource mapping).

Further, nrofSymbols may be configured to take one of a set of consecutive OFDM symbol numbers, and the set of consecutive OFDM symbol numbers may be determined by the first set of symbol numbers and the second set of symbol numbers. Meanwhile, the repetition factor may be configured to be a value of one of a set of repetition factors, and the set of repetition factors may be determined by the first repetition factor set and the second repetition factor set.

Further, the first set of symbol numbers may be { n1, n2, n4}, and the second set of symbol numbers may be { n6, n8, n12, n14}. Meanwhile, the first repetition factor set may be { n1, n2, n4}, and the second repetition factor set may be { n6, n8, n12, n14}.

Further, the set of consecutive OFDM symbol numbers may include at least one of: { n1, n2, n4, n6}, { n1, n2, n4, n8}, { n1, n2, n4, n14}, { n1, n2, n4, n6, n8}, { n1, n2, n4, n6, n14}, { n1, n2, n4, n8, n14}, { n1, n2, n4, n6, n8, n14}. Meanwhile, the set of repetition factors may include at least one of: { n1, n2, n4, n6}, { n1, n2, n4, n8}, { n1, n2, n4, n14}, { n1, n2, n4, n6, n8}, { n1, n2, n4, n6, n14}, { n1, n2, n4, n8, n14}, { n1, n2, n4, n6, n8, n14}.

Specifically, the first information is transmitted by at least one of radio resource control RRC signaling, a control unit MAC CE of the medium access control layer, and downlink control information DCI. It is understood that the network device may transmit or indicate the first information to the terminal through at least one of RRC signaling, MAC CE, DCI.

S220, the terminal acquires first information from the network equipment.

Specifically, the first information includes at least one of: resource location distribution pattern information based on a subband level, resource location distribution pattern information based on a subband. It should be noted that the subband level may be understood as a sounding reference signal resource, and the minimum granularity of the sounding reference signal resource in the frequency domain is a subband.

It should be noted that, the information of the resource location distribution manner based on the sub-band level may be used to determine the location distribution of the time-frequency domain resource used for transmitting the sounding reference signal on the sounding reference signal resource; the resource location distribution pattern information based on the sub-band may be used to determine a frequency domain location distribution for transmission of the sounding reference signal within the sub-band of the sounding reference signal resource.

The following examples of the present application will specifically describe subbands (subbands).

In one possible example, the subband size (subband size) of a subband may satisfy at least one of the following: the subband size of the subband is K PRBs, the subband size of the subband is determined by a first parameter, the subband size of the subband and the transmitted sounding reference signal bandwidth have a mapping relation, and the subband size of the subband is the minimum unit of sounding reference signal frequency hopping.

Wherein the first parameter may be used to indicate frequency hopping information of the SRS, and K is an integer greater than or equal to 1.

Specifically, K is a value in the set {4,8,12,16 }. Further, the subband size of the subband is one value of the {4,8,12,16} PRBs set. It is to be appreciated that the subband size may be configured to value one of the {4,8,12,16} PRBs, e.g., fig. 3 illustrates a schematic diagram of a subband size of 4 PRBs.

Specifically, the subband size of the subband is determined by at least one field in the first parameter. Further, the first parameter may be a frequency hopping parameter (freqhoping). Wherein at least one field in the higher layer parameter freqhoping comprises: c-SRS, b-hop. At the same time, C _SRS E {0,1,., 63} is given by the domain c-SRS contained in the higher layer parameter freqhoping, B _SRS E {0,1,2,3} is given by the domain b-SRS contained in the higher layer parameter freqhoping.

Specifically, the subband size of the subband has a mapping relationship with the transmission bandwidth of the sounding reference signal. For example, if the SRS transmission bandwidth is 64 PRBs, the subband size is 16 PRBs; if the SRS transmission bandwidth is 32 PRBs, the sub-band size is 8 PRBs; if the SRS transmission bandwidth is 16 PRBs, the subband size is 4 PRBs, etc., and is not particularly limited.

Specifically, the subband size of the subband is the minimum unit of the frequency hopping of the sounding reference signal. The minimum unit of the sounding reference signal frequency hopping can be expressed as m _SRS,b The method comprises the steps of carrying out a first treatment on the surface of the Wherein m is _SRS,b Can be determined from table 1.

Specifically, if the subband size (subband size) of the subband satisfies two, three or four of the above at least one method, the subband size of the subband is the smallest value. It will be appreciated that if the network device configures the subband sizes in two, three or four ways as described above, then the configuration with the smallest subband size is used.

Specifically, the subband size of the subbands is configured by RRC signaling. It can be appreciated that the network device configures the subband size of the subband to the terminal through RRC signaling.

In one possible example, the terminal determining a resource location distribution for transmitting the sounding reference signal according to the first information may include: and the terminal determines the position distribution of the time domain and/or frequency domain resources used for transmitting the sounding reference signal in the sounding reference signal resources according to the information of the resource position distribution mode based on the sub-band level.

Since the first information may include resource location distribution manner information based on a sub-band level and/or resource location distribution manner information based on a sub-band, and time domain and/or frequency domain resources used for transmitting the sounding reference signal may be classified into different angles of time domain resources or frequency domain resources, the embodiments of the present application will be specifically described through the following several embodiments. Among them, embodiment 1 mainly analyzes the time domain position distribution pattern based on the sub-band level, embodiment 2 mainly analyzes the frequency domain position distribution pattern based on the sub-band level, embodiment 3 mainly analyzes the frequency domain position distribution pattern based on the sub-band, and embodiment 4 mainly analyzes the time-frequency domain position distribution pattern based on the sub-band level and the sub-band.

Example 1:

in one possible example, the determining, by the terminal, location distribution first information of time domain and/or frequency domain resources for transmitting the sounding reference signal within the sounding reference signal resources according to the resource location distribution manner information based on the subband level may include: and the terminal determines time domain position distribution for transmitting the sounding reference signal in the sounding reference signal resource according to the information of the resource position distribution mode based on the sub-band level.

In embodiment 1, the time domain position distribution mode based on the subband level is mainly analyzed, and the time domain position of the SRS frequency hopping when the frequency hopping function is turned on is mainly considered in this embodiment. As can be seen from the above description, the number n of SRS hops is within one slot of the sounding reference signal resource (SRS resource) _SRS Can be defined by the parameter l'

R、

n _f 、

T _offset Or T _SRS Etc., thus n _SRS There are various forms.

For example, FIG. 4 illustrates a graph at n _SRS Time domain location distribution of SRS hopping in 6 forms. Wherein a black box represents a time domain position where a terminal can transmit an SRS, and two boxes represent 1 subband in a frequency domain and 1 box represents one OFDM symbol in a time domain. When (when)

R＝1、n _SRS When=1, fig. 4 (a) illustrates a time domain position of 1 SRS hopping, so the terminal can transmit SRS at the time domain position of SRS hopping; when (when)

R＝1、n _SRS When=2, fig. 4 (b) illustrates a time domain position of 2 times SRS hopping, and thus the terminal may transmit SRS at the time domain position of SRS hopping; when (when)

R＝2、n _SRS When=1, fig. 4 (c) illustrates a time domain position of 1 SRS hopping, so the terminal can transmit SRS at the time domain position of SRS hopping; when (when)

R＝4、n _SRS When=1, fig. 4 (d) illustrates a time domain position of 1 SRS hopping, so the terminal can transmit SRS at the time domain position of SRS hopping; when (when)

R＝2、n _SRS When=2, (e) of fig. 4 illustrates a time domain position of 2 times SRS hopping, so the terminal can transmit SRS at the time domain position of SRS hopping; when (when)

R＝1、n _SRS When=4, (f) of fig. 4 illustrates a time domain position of the SRS hopping 4 times, and thus the terminal can transmit the SRS at the time domain position of the SRS hopping.

Specifically, the information of the resource location distribution manner based on the sub-band level may include: first bit bitmap information or X bit information, X being an integer greater than or equal to 2. It may be appreciated that the terminal may determine a time domain location distribution for transmitting the sounding reference signal within the sounding reference signal resource according to the first bit bitmap information or the X bit information.

The present embodiment will specifically describe the resource location distribution mode information based on the sub-band level as first bit map (bitmap) information.

In particular, the length of the first bit bitmap information may be determined by the second parameter.

Further, the second parameter may be a higher-level parameter resource mapping. Wherein the domain in the resource mapping comprises at least one of the following: the number nrofSymbols of the continuous orthogonal frequency division multiplexing OFDM symbol, repetition factor.

Further, the first bit bitmap information may have a length of

Wherein,

represents the number of consecutive OFDM symbols (configured by RRC signaling), R is the repetition factor (configured by RRC signaling).

Specifically, the position distribution of bits in the first bit bitmap information has a correspondence with the position distribution of the time-frequency domain resource used for transmitting the sounding reference signal. The time-frequency domain resource for transmitting the sounding reference signal may be understood as an OFDM symbol for transmitting the sounding reference signal in the time domain and a subband for transmitting the sounding reference signal in the frequency domain.

Specifically, the first bit in the first bit bitmap information is used to indicate whether the terminal transmits the sounding reference signal at the time-frequency domain position corresponding to the position of the first bit, where the first bit is one bit in the first bit bitmap information.

Further, if the value of the first bit is 1, the terminal transmits the sounding reference signal at the time-frequency domain position corresponding to the position of the first bit; if the value of the first bit is 0, the terminal does not transmit the sounding reference signal at the time-frequency domain position corresponding to the position of the first bit; or if the value of the first bit is 1, the terminal does not transmit the sounding reference signal at the time-frequency domain position corresponding to the position of the first bit; if the value of the first bit is 0, the terminal transmits the sounding reference signal at the time-frequency domain position corresponding to the position of the first bit.

For example, referring to fig. 5, fig. 5 provides a schematic structural diagram of determining a time domain location distribution for transmitting a sounding reference signal in a sounding reference signal resource according to first bit bitmap information. Wherein a black box represents a time domain position where a terminal can transmit SRS, and a diagonal box and a white box represent time domain positions where a terminal cannot transmit SRS, and two boxes represent 1 subband in the frequency domain and 1 box represents one OFDM symbol in the time domain. In fig. 5 (a), the first bit bitmap information is "1", and the time domain position corresponding to the position of bit "1" in the first bit bitmap information is the time domain position of "1 SRS frequency hopping. In fig. 5 (b), the first bit bitmap information is "01", and the time domain position corresponding to the position of the first bit "1" in the first bit bitmap information is the time domain position of the "1 st SRS hopping, and the time domain position corresponding to the position of the second bit" 0 "is the time domain position of the" 2 nd SRS hopping. In fig. 5 (f), the first bit bitmap information is "1001", and the time domain position corresponding to the position of the first bit "1" in the first bit bitmap information is the time domain position of the "1 st SRS hopping, the time domain position corresponding to the position of the second bit" 0 "is the time domain position of the" 2 nd SRS hopping, the time domain position corresponding to the position of the third bit "0" is the time domain position of the "3 rd SRS hopping, and the time domain position corresponding to the position of the fourth bit" 1 "is the time domain position of the" 4 th SRS hopping. Meanwhile, it can be seen from the same principle as that of (c), (d) and (e) of fig. 5.

It can be seen that the terminal can determine, according to the first bit bitmap information, the time domain position distribution for transmitting the sounding reference signal in the sounding reference signal resource, so that it can simply and intuitively determine, according to the time domain position distribution, which time domain positions transmit the SRS and which time domain positions do not transmit the SRS, thereby improving flexibility and extensibility for SRS configuration.

The present embodiment will specifically describe the information of the resource location distribution mode based on the sub-band level as X-bit information.

Specifically, when Y time-frequency domain resources for transmitting the sounding reference signal are configured in one time slot of the sounding reference signal resources and Y is greater than or equal to 1, if Y is 1, the X-bit information is used as a reserved bit; and/or if Y is less than or equal to X, whether the terminal transmits the sounding reference signal on Y time-frequency domain resources is indicated by bits in the X-bit information; and/or if Y is greater than X, if the terminal transmits the sounding reference signal on the remaining sounding reference signal in the Y time-frequency domain resources by repeatedly using the bits in the X-bit information, except if the terminal transmits the sounding reference signal on the X time-frequency domain resources in the Y time-frequency domain resources by the bits in the X-bit information.

Specifically, if the bit value in the X-bit information is 1, the terminal transmits a sounding reference signal at a time domain position corresponding to the bit; if the value of the bit in the X bit information is 0, the terminal does not transmit the detection reference signal at the time domain position corresponding to the bit; or if the value of the bit in the X bit information is 1, the terminal does not transmit the sounding reference signal at the time domain position corresponding to the bit; if the value of the bit in the X-bit information is 0, the terminal transmits the sounding reference signal at the time domain position corresponding to the bit.

For example, when X is 2, the resource location distribution manner information based on the subband level is 2-bit information. For (a), (c) and (d) of fig. 4, since only 1 SRS hops within one slot, the 2-bit information serves as a reserved bit. For (b) and (e) of fig. 4, bits in the 2-bit information are used to indicate whether the terminal transmits SRS at the time domain position of SRS in 2 SRS hops. For (f) of fig. 4, bits in the 2-bit information may be used to indicate whether the terminal transmits the SRS at the time domain position of the last 2 SRS hops of the 4 SRS hops, in addition to indicating whether the terminal transmits the SRS at the time domain position of the last 2 SRS hops of the 4 SRS hops. For example, in the case where the time domain position for the 4 times SRS hopping in (f) of fig. 4 is configured as "1010", the third bit and the fourth bit in "1010" are the reuse of the first bit and the second bit to be configured.

Therefore, the terminal can determine which time domain positions transmit SRS according to the time domain position distribution, and which time domain positions do not transmit SRS, so that the flexibility and expansibility of SRS configuration are improved. In addition, the complexity of the scheduling process at the network equipment side can be well controlled while the flexibility is ensured.

The embodiment will specifically describe the resource location distribution mode information based on the sub-band level and the time domain resource compression mode information.

In one possible example, the sub-band level based resource location distribution pattern information further includes: the time domain resource compression mode information can be used for compressing time domain position distribution of sounding reference signal transmission.

Specifically, compressing the time domain location distribution of the sounding reference signal frequency hopping may include the following operations: reducing OFDM symbol intervals between time domain positions of two continuous sounding reference signal transmissions in time-frequency domain resources of the sounding reference signal transmissions; alternatively, the time domain position of the sounding reference signal frequency hopping is compressed forward by at least one OFDM symbol not used for sounding reference signal frequency hopping.

For example, referring to fig. 6, fig. 6 is a schematic structural diagram of a time domain location distribution of compressed sounding reference signal frequency hopping according to an embodiment of the present application. Wherein, the black box represents a time domain position where the terminal can be used to transmit SRS, and the diagonal box and the white box represent time domain positions where the terminal cannot be used to transmit SRS. The "time domain position of SRS hopping" in fig. 6 (b) is compressed forward by 1 OFDM symbol not used for SRS hopping to obtain the position distribution shown in fig. 6 (a), and the "time domain position of SRS hopping" in fig. 6 (b) is compressed forward by 2 OFDM symbols not used for SRS hopping to obtain the position distribution shown in fig. 6 (c), thereby reducing the OFDM symbol interval between time domain positions of consecutive two sounding reference signal transmissions.

Therefore, by configuring the time domain resource compression mode information, the time interval for transmitting the SRS is reduced, more different resource position distributions can be obtained by the compression mode, and the flexibility and expansibility for SRS configuration are improved.

Example 2:

in one possible example, the determining, by the terminal, location distribution first information of time domain and/or frequency domain resources for transmitting the sounding reference signal within the sounding reference signal resources according to the resource location distribution manner information based on the subband level may include: and the terminal determines the frequency domain position distribution for transmitting the sounding reference signal in the sounding reference signal resource according to the information of the resource position distribution mode based on the sub-band level.

In embodiment 2, the frequency domain position distribution pattern based on the subband level is mainly analyzed, and this embodiment isThe frequency domain position of SRS hopping when the frequency hopping function is turned on may be considered, or the frequency domain position of SRS transmission when the frequency hopping function is not turned on may be considered. In addition, in the present embodiment, when analyzing the frequency domain position of SRS frequency hopping or transmission, it is necessary to know how many subbands are configured in the sounding reference signal resource for SRS frequency hopping or transmission. Meanwhile, as described in the above embodiment, n in the present embodiment when considering the turn-on of the frequency hopping function _SRS And also in various forms.

For example, fig. 7 illustrates frequency domain resources for 4 SRS hopping or transmission. Wherein a black box represents a frequency domain position where a terminal can transmit an SRS, and two boxes represent 1 subband in the frequency domain and 1 box represents one OFDM symbol in the time domain. Fig. 7 (a) illustrates 1 subband configured on the frequency domain of the sounding reference signal resource for SRS hopping or transmission, and thus the terminal may transmit SRS on the 1 subband. Fig. 7 (b) illustrates 2 subbands configured on the frequency domain of the sounding reference signal resource for SRS hopping or transmission, and thus the terminal can transmit SRS on the 2 subbands. Fig. 7 (c) illustrates 2 subbands configured on the frequency domain of the sounding reference signal resource for SRS hopping or transmission, and thus the terminal can transmit SRS on the 2 subbands. Fig. 7 (d) illustrates 4 subbands configured on the frequency domain of the sounding reference signal resource for SRS hopping or transmission, and thus the terminal can transmit SRS on the 4 subbands.

Specifically, the information of the resource location distribution manner based on the sub-band level may include: first bit bitmap information or X bit information, X being an integer greater than or equal to 2. It may be appreciated that the terminal may determine a frequency domain location distribution for transmitting the sounding reference signal within the sounding reference signal resource according to the first bit bitmap information or the X-bit information.

In accordance with the foregoing first bit map information, the present embodiment will be described below in detail with respect to the first bit map information based on the sub-band level resource location distribution mode information.

Specifically, the length of the first bit bitmap information may be determined by the number of subbands of the subbands configured within the sounding reference signal resource.

Further, the length of the first bit bitmap information may be determined by the number of subbands configured in the sounding reference signal resource for sounding reference signal frequency hopping or transmission.

Further, the first bit bitmap information may have a length of N _subband bits. Wherein N is _subband Indicating the number of subbands configured within the sounding reference signal resource for sounding reference signal hopping or transmission.

Further, the first bit bitmap information has a correspondence relationship from low order to high order and the frequency domain of the sounding reference signal resource from low order to high order.

For example, referring to fig. 8, fig. 8 provides a schematic structural diagram of determining a frequency domain location distribution for transmitting a sounding reference signal in a sounding reference signal resource according to second bitmap information. Where a black box represents a frequency domain position where a terminal can transmit SRS, and a diagonal box and a white box represent frequency domain positions where a terminal cannot transmit SRS, and two boxes represent 1 subband in the frequency domain and 1 box represents one OFDM symbol in the time domain. In fig. 8 (a), the first bit bitmap information is "1", and the frequency domain position corresponding to the position of bit "1" in the first bit bitmap information is "1 subband for transmitting SRS configured on the frequency domain of the sounding reference signal resource". In fig. 8 (c), the first bit bitmap information is "10", and the frequency domain position corresponding to the 1 st bit "1" in the first bit bitmap information is "the 1 st subband for transmitting SRS configured on the frequency domain of the sounding reference signal resource", and the frequency domain position corresponding to the 2 nd bit "0" is "the 2 nd subband for transmitting SRS configured on the frequency domain of the sounding reference signal resource". Meanwhile, it can be seen from the same principle as that of fig. 8 (b) and (d).

Therefore, the terminal can determine the frequency domain position distribution for transmitting the sounding reference signal in the sounding reference signal resource according to the first bit bitmap information, so that the terminal can simply and intuitively determine which frequency domain positions transmit the SRS according to the frequency domain position distribution and which frequency domain positions do not transmit the SRS, thereby ensuring that the configuration of the SRS has better flexibility and expansibility. In addition, embodiment 2 can extend SRS transmission only when frequency hopping is supported in embodiment 1 to the case where both frequency hopping and non-frequency hopping are supported.

In the above-mentioned agreement for the X-bit information, the embodiments of the present application will specifically describe that the information of the resource location distribution manner based on the subband level is the X-bit information.

For example, please refer to fig. 9. Where a black box represents a frequency domain position where a terminal can transmit SRS, and a diagonal box and a white box represent frequency domain positions where a terminal cannot transmit SRS, and two boxes represent 1 subband in the frequency domain and 1 box represents one OFDM symbol in the time domain. When X is 2, the resource location distribution pattern information based on the subband level is 2-bit information. For (a) of fig. 9, in case that 1 subband for sounding reference signal hopping or transmission is configured within the sounding reference signal resource, the 2-bit information is used as a reserved bit. For (d) of fig. 9, in case that 4 subbands for sounding reference signal hopping or transmission are configured within the sounding reference signal resource, bits in the 2-bit information may indicate whether the terminal transmits SRS on other subbands in the 4 subbands by repeatedly using bits in the 2-bit information, in addition to indicating whether the terminal transmits SRS on the first 2 subbands in the 4 subbands. Meanwhile, it can be seen from the same principle as that of fig. 9 (b) and (c).

Therefore, the terminal can determine the frequency domain position distribution used for transmitting the sounding reference signal in the sounding reference signal resource according to the X-bit information, so that the terminal can simply and intuitively determine which frequency domain positions transmit SRS according to the frequency domain position distribution and which frequency domain positions do not transmit SRS, thereby improving the flexibility and expansibility for SRS configuration. In addition, the complexity of the scheduling process at the network equipment side can be well controlled while the flexibility is ensured.

The embodiments of the present application will specifically describe the resource location distribution mode information based on the sub-band level and the time domain resource compression mode information.

In one possible example, the sub-band level based resource location distribution pattern information further includes: the time domain resource compression mode information can be used for compressing time domain position distribution of frequency hopping of the sounding reference signal.

Note that, the time domain resource compression mode information in this embodiment is identical to that in the above embodiment 1, and will not be described here again.

Example 3:

in one possible example, the terminal determining a resource location distribution for transmitting the sounding reference signal according to the first information may include: the terminal determines the frequency domain position distribution used for transmitting the sounding reference signal in the sub-band according to the information based on the resource position distribution mode in the sub-band.

In embodiment 3, the frequency domain position distribution in the sub-band of the sounding reference signal resource is mainly analyzed, and the sounding reference signal is transmitted according to the frequency domain position distribution in the sub-band. Wherein the frequency domain resources within a subband may be determined by the subband size of the subband.

For example, referring to fig. 10, when the subband size of a subband is 4 PRBs, fig. 10 illustrates 15 forms of frequency domain location distribution within the subband. Wherein the black box represents the frequency domain position where the terminal in the sub-band can be used to transmit SRS, and the white box represents the frequency domain position where the terminal in the sub-band cannot be used to transmit SRS.

Specifically, the information of the distribution manner of the resource position in the sub-band may include at least one of the following: the second bit map information, M bit information and S pieces of first indication domain information, M is an integer greater than or equal to 1, and S is an integer greater than or equal to 1. It is understood that the terminal may determine a frequency domain location distribution for transmitting the sounding reference signal within the sub-band according to the second bit bitmap information, the M-bit information, or the S first indication domain information.

The present embodiment will specifically describe the second bit map information based on the resource location distribution mode information in the sub-band.

Specifically, the length of the second bit map information satisfies at least one of the following ways: the length of the second bit map information is L bits, and the length of the second bit map information is determined by the number of PRBs included in the subband size of the subband. The length of the second bit map information may be smaller than or equal to the number of PRBs included in the subband size, or may be larger than the number of PRBs included in the subband size. For example, the second bitmap information has a length of 4bits, and the sub-band size contains 8 PRBs.

Wherein K is an integer greater than or equal to 1.

Further, K is one of the bits of the set {4,8,12,16 }. It will be appreciated that the length of the second bit map information may be one of the set {4,8,12,16} bits. Further, the second bit map information may have a length of

Wherein,

the number of PRBs included in the subband size of the subband in the sounding reference signal resource is represented.

Specifically, the bit positions in the second bit map information have a correspondence with the frequency domain position distribution used for transmitting the sounding reference signal in the sub-band. The frequency domain position used for transmitting the sounding reference signal is understood to be the position of the PRB used for transmitting the sounding reference signal in the subband.

Further, the second bit map information has a correspondence between the low order bit and the high order bit and the frequency domain of the subband in the sounding reference signal resource from low to high.

Specifically, a second bit in the second bit map information is used to indicate whether the terminal transmits a sounding reference signal at a frequency domain position in the subband corresponding to the position of the second bit, where the second bit is one bit in the second bit map information.

Further, if the value of the second bit is 1, the terminal transmits the sounding reference signal at a frequency domain position in the sub-band corresponding to the position of the second bit; if the value of the second bit is 0, the terminal does not transmit the sounding reference signal at the frequency domain position in the sub-band corresponding to the second bit; or if the value of the second bit is 1, the terminal does not transmit the sounding reference signal at the frequency domain position in the sub-band corresponding to the position of the second bit; if the value of the second bit is 0, the terminal transmits the sounding reference signal at the frequency domain position in the sub-band corresponding to the second bit.

For example, referring to fig. 11, fig. 11 provides a schematic structural diagram of determining a frequency domain location distribution for transmitting sounding reference signals in a subband according to the second bit map information. Wherein, the black box represents the frequency domain position where the terminal can be used to transmit SRS, and the diagonal box and the white box represent the frequency domain position where the terminal cannot be used to transmit SRS. In fig. 11 (a), the second bit map information is "1010", and the frequency domain position corresponding to the position of the first bit "1" in the second bit map information is "PRB for transmitting SRS first in the subband", the frequency domain position corresponding to the position of the second bit "0" is "PRB for transmitting SRS second in the subband", the frequency domain position corresponding to the position of the third bit "1" is "PRB for transmitting SRS third in the subband", and the frequency domain position corresponding to the position of the fourth bit "0" is "PRB for transmitting SRS fourth in the subband". Meanwhile, it can be seen from the same principle as that of (b), (c), (d), (e) and (f) of fig. 11.

Therefore, the terminal can determine the frequency domain position distribution used for transmitting the sounding reference signal in the sub-band according to the second bit bitmap information, so that the terminal can simply and intuitively determine which frequency domain positions transmit the SRS according to the frequency domain position distribution in the sub-band, and which frequency domain positions do not transmit the SRS, thereby ensuring that the configuration of the SRS has better flexibility and expansibility.

The following embodiments of the present application will specifically describe the information based on the distribution mode of the resource location in the sub-band as M-bit information.

Mode one:

in one possible example, all bits in the M-bit information indicate a frequency domain location distribution within the subband for transmission of the sounding reference signal in a code combination.

Note that, when only 6 types of information shown in (f), (g), (l), (M), (n), and (o) in fig. 10 exist in the subband, the M-bit information may be 3bits information, and all bits in the 3bits information indicate the 6 types in a coding combination manner, for example, "000" indicates (f) in fig. 10, "001" indicates (g) in fig. 10, "010" indicates (l) in fig. 10, and the like, which is not particularly limited. When only 10 types of the types shown in (f) to (o) of fig. 10 exist in a subband, M-bit information may be 4bits information, and all bits in the 4bits information indicate the 10 types in a coded combination manner, for example, "0000" indicates (f) of fig. 10, etc. When only the 4 forms shown in (b) to (e) of fig. 10 exist in the sub-band, the M-bit information may be 2bits information, and all bits in the 2bits information indicate the 4 forms in a coding combination manner, for example, "00" indicates (b) of fig. 10, etc., without being particularly limited thereto.

Mode two:

in one possible example, N bits in the M-bit information are used to indicate the number P of frequency domain resources used for transmitting the sounding reference signal in the subband, N is an integer greater than or equal to 1, and P is the number of PRBs contained in a subband size smaller than or equal to the subband; the rest bits except N bits in the M-bit information indicate the position distribution of P frequency domain resources in the sub-band according to a coding combination mode.

Specifically, the value of N may be determined by the number of modes in the subband in which the number of frequency domain resources for transmitting the sounding reference signal exists. It should be noted that, when the number of frequency domain resources used for transmitting SRS in the subband configured by the known network device only has two modes (such as P e {1,2 }), the value of N may be 1. At this time, the two modes may be indicated with 1 bit in the M-bit information. For example, the 1 bit is "0" to indicate that P is 1, and the 1 bit is "1" to indicate that P is 2. When the number of frequency domain resources used for transmitting SRS in the subband configured by the network device is known to have only four modes (e.g., P e {1,2,3,4 }), the value of N may be 2. At this time, the four modes may be indicated with 2 bits in the M-bit information. For example, the 2 bits are "00" to indicate P as 1, the 1 bits are "01" to indicate P as 2, etc., which is not particularly limited.

Specifically, the value of N may be determined by the number of PRBs included in the subband size of the subband. When the subband size of the subband includes 4 PRBs, the value of N may be 3. At this time, the number P of frequency domain resources for transmitting SRS in the subband may be indicated in a coding combination manner with 3bits in the M-bit information. For example, the 3bits are "000" to indicate P as 0, the 3bits are "001" to indicate P as 1, the 3bits are "100" to indicate P as 4, etc., which is not particularly limited. When the number of PRBs included in the subband size of the subband is 8, the value of N may be 4. At this time, the number P of frequency domain resources for transmitting SRS in the subband may be indicated in a coding combination manner with 4 bits in the M-bit information. For example, the 4 bits are "0000" to indicate P as 0, the 3bits are "1000" to indicate P as 8, etc., which is not particularly limited.

Example 1: when there are only 6 types of information shown in (f), (g), (l), (M), (N), (o) in fig. 10 in a subband, and M-bit information is 3bits of information, since the number of frequency domain resources for transmitting a sounding reference signal in a subband configured by a known network device only has two modes (i.e., P e {1,2 }), the value of N is 1. At this time, the first bit in the 3bits information is used to indicate that the number P of frequency domain resources used for transmitting SRS in the subband is 1 or 2. Wherein a first bit of "0" indicates that P is 2 and a first bit of "1" indicates that P is 1. Thus, the 3bits information is "00x" indicating (f) in fig. 10, and "x" indicates a reserved bit; the 3bits information being "01x" indicates (g) in fig. 10; the 3bits information being "100" indicates (i) in fig. 10; the 3bits information being "101" indicates (m) in fig. 10; the 3bits information being "110" indicates (n) in fig. 10; the 3bits information is "111" indicating (o) in fig. 10.

Example 2: when there are only 8 types of information shown in (f), (g), (h), (i), (l), (M), (N), and (o) in fig. 10 in the sub-band, and the M-bit information is 3bits of information, since the number of frequency domain resources for transmitting the sounding reference signal in the sub-band configured by the known network device only has two modes (i.e., P e {1,2 }), the value of N is 1. At this time, the first bit in the 3bits information is used to indicate that the number P of frequency domain resources used for transmitting SRS in the subband is 1 or 2. Wherein a first bit of "0" indicates that P is 2 and a first bit of "1" indicates that P is 1. Thus, the 3bits information being "000" indicates (f) in fig. 10; the 3bits information being "001" indicates (g) in fig. 10; the 3bits information being "010" indicates (h) in fig. 10; the 3bits information being "011" indicates (i) in fig. 10; the 3bits information being "100" indicates (i) in fig. 10; the 3bits information being "101" indicates (m) in fig. 10; the 3bits information being "110" indicates (n) in fig. 10; the 3bits information is "111" indicating (o) in fig. 10.

Therefore, the terminal can determine the frequency domain position distribution for transmitting the SRS in the sounding reference signal resource according to the K bit information, so that the terminal can simply and intuitively determine which frequency domain positions transmit the SRS according to the frequency domain position distribution and which frequency domain positions do not transmit the SRS, thereby improving the flexibility and expansibility for SRS configuration. In addition, the complexity of the scheduling process at the network equipment side can be well controlled while the flexibility is ensured.

The following embodiments of the present application will specifically describe the information of the distribution manner of the resource location in the sub-band as S pieces of first indication domain information.

Specifically, the value of S may be determined by the number of modes existing in the number of frequency domain resources used for transmitting the sounding reference signal in the subband. The first indication field is used for indicating the number Q of frequency domain resources used for transmitting the sounding reference signal in the sub-band, and Q is less than or equal to the number of PRBs contained in the sub-band size of the sub-band.

It should be noted that, when the number of frequency domain resources used for transmitting SRS in the subband configured by the known network device only has two modes (such as q∈ {1,2 }), the value of S may be 2. At this time, the network device may indicate the two modes with 2 pieces of first indication field information, respectively. For example, the 1 st first indication field information is used to indicate that Q is 1, and the 2 nd first indication field information is used to indicate that Q is 2. When the number of frequency domain resources used for transmitting SRS in the subband configured by the network device is known to have only four modes (e.g., Q e {1,2,3,4 }), the value of S may be 4. At this time, the network device may indicate the four modes with the 4 pieces of first indication field information, respectively. For example, the 1 st first indication field information is used for indicating that Q is 1, the 2 nd first indication field information is used for indicating that Q is 2, the 3 rd first indication field information is used for indicating that Q is 3, and the 4 th first indication field information is used for indicating that Q is 4.

Further, the first indication domain information includes R bit information, all bits in the R bit information indicate a position distribution of Q frequency domain resources in a subband according to a coding combination mode, and R is an integer greater than or equal to 1.

Example 1: when there are only 6 forms shown in (f), (g), (l), (m), (n), (o) in fig. 10 in the sub-band, the value of S is 2 because the number of frequency domain resources for transmitting SRS in the sub-band configured by the known network device only has two modes (i.e., Q e {1,2 }). At this time, the network device may indicate the two modes with 2 pieces of first indication field information, respectively. The 1 st first indication domain information is used for indicating that Q is 2, and the 2 nd first indication domain information is used for indicating that Q is 1. Meanwhile, the 1 st first indicated domain information contains 1bit information, and the 2 nd first indicated domain information contains 2bits information. Thus, the 1bit information being "1" indicates (f) in fig. 10; the 1bit information being "0" indicates (g) in fig. 10; the 2bits information being "00" indicates (i) in fig. 10; the 2bits information being "01" indicates (m) in fig. 10; the 2bits information being "10" indicates (n) in fig. 10; the 2bits information being "11" indicates (o) in fig. 10.

Example 2: when there are only 8 forms in the sub-band shown in (f), (g), (h), (i), (l), (m), (n), (o) in fig. 10, the number of frequency domain resources used for transmitting SRS in the sub-band configured by the known network device only has two modes (i.e., Q e {1,2 }), so the value of S is 2. At this time, the network device may indicate the two modes with 2 pieces of first indication field information, respectively. The 1 st first indication domain information is used for indicating that Q is 2, and the 2 nd first indication domain information is used for indicating that Q is 1. Meanwhile, the 1 st first indicated domain information contains 2bits of information, and the 2 nd first indicated domain information contains 2bits of information. Therefore, 2bits information in the 1 st first indication field information is "00" indicating (f) in fig. 10; the 2bits information in the 1 st first indication field information is "01" indicating (g) in fig. 10; the 2bits information in the 1 st first indication field information is "10" indicating (h) in fig. 10; the 2bits information in the 1 st first indication field information is "11" indicating (i) in fig. 10; the 2bits information in the 2 nd first indication field information is "00" indicating (l) in fig. 10; the 2bits information in the 2 nd first indication field information is "01" indicating (m) in fig. 10; the 2bits information in the 2 nd first indication field information is "10" indicating (n) in fig. 10; the 2bits information in the 2 nd first indication field information is "11" indicating (o) in fig. 10.

Therefore, the terminal can simply and intuitively determine which frequency domain positions transmit the SRS according to the frequency domain position distribution, and which frequency domain positions do not transmit the SRS, thereby improving the flexibility and expansibility of SRS configuration. In addition, the flexibility is ensured, and meanwhile, good readability is ensured.

In one possible example, the terminal determines a frequency domain location distribution for transmitting sounding reference signals in a sub-band according to resource location distribution pattern information based on the sub-band, including: the terminal determines the frequency domain position distribution in the sub-band for transmitting the sounding reference signal in a repeated or same transmission mode based on the resource position distribution mode information in the sub-band.

In embodiment 3, a specific description is given of how to determine the frequency domain position distribution for transmitting SRS in the subband according to the information based on the resource position distribution pattern in the subband, by using the case where the subband size of the subband is 4 PPRs. Therefore, for the case where the subband size of the subband is 8, 12, 16 or more PRBs, the position distribution when the subband size is 8, 12, 16 or more PRBs can be determined by using the reuse or the same transmission mode for the information of the resource position distribution in the subband based on the frequency domain position distribution for SRS transmission in 4 PRBs determined based on the information of the resource position distribution in the subband in embodiment 3 as a basis.

For example 1, (a) in fig. 12 is an example of the frequency domain location distribution for SRS transmission within 4 PRBs determined based on the intra-subband resource location distribution pattern information in embodiment 3, and thus the frequency domain location distribution for SRS transmission within 8 PRBs is determined in a repeated manner based on the intra-subband resource location distribution pattern information as shown in (b) in fig. 12.

For example 2, (a) in fig. 13 is an example of the frequency domain location distribution for SRS transmission within 4 PRBs determined based on the intra-subband resource location distribution pattern information in embodiment 3, and thus the frequency domain location distribution for SRS transmission within 8 PRBs is determined in the same transmission mode based on the intra-subband resource location distribution pattern information as shown in (b) in fig. 13.

Example 4:

in one possible example, the terminal determining a resource location distribution for transmitting the sounding reference signal according to the first information may include: and the terminal determines the time-frequency domain position distribution used for transmitting the sounding reference signal in the sounding reference signal resource according to the resource position distribution mode information based on the sub-band level and the resource position distribution mode information based on the sub-band.

In embodiment 4, the time-frequency domain position distribution for transmitting the sounding reference signal in the sounding reference signal resource is mainly analyzed when the first information is the information of the resource position distribution pattern based on the subband level and the information of the resource position distribution pattern based on the subband. Therefore, the specific technical solution in embodiment 4 is identical to the technical solutions in
