[0029] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] The following is a brief description of the relevant background involved in the present invention, as shown below:

[0031] 1. Sounding Reference Signal (SRS)

[0032] The SRS signal is an important reference signal in the 5G / NR (New Radio) system and is widely used in various functions in the NR system, such as:

[0033] (1) UE sounding procedure for DL ​​CSI (DownLink Channel State Information) acquisition;

[0034] (2) Used for uplink beam management;

[0035] (3) Used for positioning function;

[0036] (4) Coordinate with codebook-based uplink transmission (including frequency domain scheduling and rank / precoding matrix indicator (PMI) / modulation coding scheme (MCS) determination);

[0037] (5) Cooperate with non-codebook based uplink transmission (including frequency domain scheduling and determination of SRS resource indication (Sounding Reference Signal Resource Indicator, SRI) / MCS).

[0038] The network may configure one or more SRS Resource sets (SRS resource groups) for a user equipment (User Equipment, UE), and each SRS Resource set may be configured with one or more SRS resources (SRS resources).

[0039] SRS transmission can be divided into periodic, semi-persistent, and aperiodic. The details are as follows:

[0040] (1) Periodic SRS and semi-continuous SRS

[0041] Periodic SRS refers to a periodically transmitted SRS, whose period and time slot offset are configured by Radio Resource Control (RRC) signaling. Once the terminal receives the corresponding configuration parameters, it sends SRS at a certain period until the RRC configuration becomes invalid. The spatial related information (Spatial Relation Info, which indicates the transmission beam in an implicit way) of the periodic SRS is also configured by RRC signaling. The spatial related information may indicate a CSI-RS (Channel State Information Reference signal), SSB (Synchronization Signal Block) or reference SRS. The terminal determines the transmission beam of the third SRS resource based on the indicated CSI-RS / SSB receiving beam, or determines the transmission beam of the third SRS resource based on the transmission beam of the reference SRS resource.

[0042] Semi-persistent SRS is also a periodically transmitted SRS. The period and slot offset are configured by RRC signaling, but its activation and deactivation signaling is carried by the Media Access Control Element (MAC CE). After receiving the activation signaling, the terminal starts to transmit SRS periodically until it receives the deactivation signaling. The spatial related information (transmit beam) of the semi-persistent SRS is carried together with the MAC CE that activates the SRS.

[0043] After receiving the period and time slot offset configured by RRC, the terminal determines the time slot that can be used to transmit SRS according to the following formula (1):

[0044]

[0045] Among them, T SRS and Toffset is the configured period and offset, n f and They are the radio frame and time slot numbers respectively.

[0046] (2) Aperiodic SRS transmission

[0047] Aperiodic SRS transmission is introduced in the NR system, and the base station can trigger the SRS transmission of the terminal through the uplink or downlink DCI (Downlink Control Information). The trigger signaling used to trigger the aperiodic SRS transmission can be carried by the DCI for scheduling PUSCH (Physical Uplink Share Channel) / PDSCH (Physical Downlink Share Channel) in the UE (User Equipment) exclusive search space, or by DCI format 2_3 in the public search space. Among them, DCI format 2_3 can not only be used to trigger aperiodic SRS transmission, but also can be used to configure the transmission power control (TPC) command of SRS on a group of UEs or a group of carriers.

[0048] Table 1: SRS trigger signaling

[0049]

[0050] After receiving the non-periodic SRS trigger signaling (such as DCI), the terminal transmits SRS on the SRS resource set indicated by the trigger signaling. Among them, the slot offset between the trigger signaling and the SRS transmission is configured by high-level signaling (RRC). The network side pre-indicates the configuration parameters of each SRS resource set of the terminal through high-level signaling, including time-frequency resources, sequence parameters, power control parameters, etc. In addition, for each SRS resource in the triggered SRS resource set, the terminal can also determine the transmit beam used to transmit SRS on the resource through the spatial related information of the resource, and this information is configured to each SRS resource through RRC.

[0051] Among them, for the slot offset, if the UE receives the DCI signaling that triggers the aperiodic SRS in time slot n, the UE will Send the SRS resources in the corresponding collection, as follows Figure 1AAs shown in FIG. 1 , k is the RRC parameter slotOffset configured for each set, and μSRS and μPDCCH are the subcarrier spacing configurations of the triggered SRS and PDCCH carrying the trigger command, respectively.

[0052] 2. SRS time domain resource configuration:

[0053] startPosition INTEGER(0..13):l offset ∈{0, 1, ..., 13};

[0054] nrofSymbols ENUMERATED{n1, n2, n4}: number of consecutive OFDM symbols

[0055] That is, each SRS resource can be configured in any symbol of a time slot;

[0056] The time domain start symbol of SRS, That is, count down from the last symbol of the time slot. Figure 1B As shown, it is a schematic diagram of SRS time domain resource configuration.

[0057] 3. SRS resource frequency domain configuration:

[0058] The frequency domain configuration of SRS is determined by parameter C in 38.211-Table 6.4.1.4.3-1 SRS , B SRS (determined by RRC signaling configuration), m SRS，b The number of physical resource blocks (PRBs) for SRS transmission, where b = B SRS .

[0059] Table 2 SRS bandwidth configuration

[0060]

[0061] The sequence length of the SRS resource is determined by the following formula. The sequence length of the SRS resource is the number of occupied subcarriers:

[0062]

[0063] The frequency domain starting position of the SRS resource is determined by the following formula:

[0064]

[0065] in,

[0066]

[0067]

[0068] Among them, K TC The number of comb configurations. The number of subcarriers occupied by one RB. shift Configure parameters for high-level layers.

[0069] The NR system supports SRS frequency hopping. If b is met hop <B SRS In the case of (where b hop is the RRC configuration parameter), the terminal sends the SRS signal in the form of frequency hopping. SRS，0 is the total bandwidth of SRS frequency hopping, m SRS，b is the number of PRBs sent for each frequency hopping. The terminal determines the frequency domain position of each frequency hopping by the following formula, n b is the frequency domain position index parameter:

[0070]

[0071] N b Determined from Table 2 above, n RRC is the RRC configuration parameter, where F b (n SRS ) is determined by the following formula:

[0072]

[0073] Among them, no matter N b The value of the parameter, Parameter n SRS Indicates the number of SRS frequency hopping. For non-periodic SRS, the number of SRS frequency hopping is determined by the following formula:

[0074]

[0075] in, is the number of consecutive OFDM symbols (RRC configuration parameter), and R is the repetition factor (RRC configuration) 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.

[0076] For periodic and semi-periodic SRS, the number of SRS frequency hopping is determined by the following formula:

[0077]

[0078] Among them, T SRS and T offset is the configured period and offset, n f and are the radio frame and time slot numbers, respectively. is the number of time slots contained in each frame.

[0079] According to the current protocol configuration, the network equipment configures bandwidth and frequency hopping parameters for each SRS resource. SRS resources are transmitted in the configured bandwidth. If the frequency domain position or bandwidth size of the channel detected by SRS needs to be changed at the next moment, it needs to be configured through RRC. In addition, considering that the channel conditions of adjacent bandwidths are similar, cross-subband SRS is introduced to detect channels at different frequency band positions, so that a larger channel bandwidth can be detected under the same conditions. And by adjusting the configuration of parameters, the effect of partial frequency hopping can be achieved to support stronger coverage and greater capacity.

[0080] To solve the above problems, possible solutions are to flexibly configure the SRS transmission bandwidth and transmit SRS across subbands. The above two methods have better flexibility and can more dynamically indicate the frequency domain location and bandwidth size of the SRS transmission resource.

That is, it can be understood that one S of the bandwidth that can be used to transmit the SRS resource is the bandwidth for sending the first SRS resource.

[0137] Optionally, the terminal device determines the starting position of the first SRS frequency domain based on the second information; determines the initial position of the frequency domain transmission based on the first SRS frequency domain starting position, the number of PRBs transmitted by the first SRS resource and the second indication information.

[0138] Exemplarily, the terminal device determines the initial position of the frequency domain transmission. After the first SRS frequency domain starting position of the second information is determined by formula 2, the second SRS frequency domain starting position is further determined by the second indication information in the first information. The second SRS frequency domain starting position is the starting position of the second SRS transmission bandwidth. Specifically, the second SRS frequency domain starting position is the first SRS frequency domain starting position plus m SRS，b One S part of the SRS transmission bandwidth is multiplied by Y. Wherein, S is S equal parts of the available SRS transmission bandwidth in the first indication information of the second information, Y is the second indication information in the second information, and the value range of Y is [0, S-1].

[0139] For example:

[0140]

[0141] (5) The terminal device determines whether to perform frequency hopping according to the second information.

[0142] For example, (1) if b hop ≥B SRS , frequency hopping is not enabled. The frequency hopping parameter is determined according to the high-level configuration parameter, the number of PRBs for transmitting the first SRS resource, and the preset parameter.

[0143] For example, the following frequency domain position index is used to determine the transmission position in the second SRS transmission bandwidth: Among them, m′ SRS，b is the number of PRBs transmitted for the first SRS resource, n RRC N is the high-level configuration parameter. b is the preset parameter obtained according to the above Table 2. hop RRC configuration parameters, B SRS Configure parameters for RRC.

[0144] (2) If b hop <B SRS , start frequency hopping. Determine frequency hopping parameters according to high-level configuration parameters, a function related to the number of frequency hopping times, the number of PRBs transmitted by the first SRS resource, and preset parameters.

[0145] For example, the following frequency domain position index is used to determine the transmission position in the second SRS transmission bandwidth:

[0146] Among them, F b (n SRS ) is a function related to the number of frequency hopping, n SRS is the frequency hopping times, m′ SRS，b is the number of PRBs transmitted for the first SRS resource, n RRC N is the high-level configuration parameter. b are the preset parameters obtained according to Table 2 above;

[0147] in,

[0148] It can be understood that, for example, when the terminal device is configured to enable frequency hopping. Figure 4A As shown in FIG. 1 , it is a schematic diagram of the frequency domain position of the SRS resource transmission specified in the existing protocol. Figure 4B FIG. 1 is a schematic diagram of the frequency domain position of the SRS resource sent by the terminal device in an embodiment of the present invention. Figure 4B As shown, the configuration S=2, Y=1. That is, the bandwidth available for transmission of the SRS resource is divided into two equal parts, and Y indicates that the first SRS resource is transmitted on the second equal part. The number of subcarriers occupied by the first SRS resource is half of the original number.

[0149] Optionally, the first information and the second information are transmitted via the same RRC signaling.

[0150] Optionally, the network device receives the first SRS resource sent by the terminal device for beam management or uplink codebook channel measurement or antenna switching or non-codebook purposes.

[0151] In an embodiment of the present invention, a terminal device receives first information sent by a network device, and the first information can be used to dynamically indicate the frequency domain position of the first SRS resource; the terminal device determines the frequency domain position of the first SRS resource based on the first information; and the terminal device sends the first SRS resource to the network device based on the first information. The network device can flexibly configure the frequency domain position of the SRS resource for the terminal device. For example, the parameter configuration dynamically adjusts the bandwidth and frequency domain position of the SRS resource transmission. The advantage of this solution is that there is no need to configure multiple SRS resources in different frequency domain positions, and there is no need to frequently add or release SRS resources. The convenience brought by the flexibility of dynamic triggering can be reasonably utilized.

[0152] like Figure 5 As shown, it is a schematic diagram of another embodiment of the method for configuring SRS transmission resources in an embodiment of the present invention, which may include:

[0153] 501. A network device sends second information to a terminal device, where the second information includes configuration information of a sounding signal SRS resource set.

[0154] 502. The terminal device determines configuration information of the SRS resource set according to the second information.

[0155] It should be noted that steps 501 and 502 can refer to Figure 3 In the illustrated embodiment, steps 301 and 302, and steps 501 and 502 are optional steps.

[0156] 503. The network device sends first information to the terminal device, where the first information is used to indicate a frequency domain position of a second SRS resource, where the second SRS resource is an SRS resource transmitted across subbands.

[0157] Optionally, the terminal device receives first information sent by the network device.

[0158] 504. The terminal device determines the frequency domain position of the second SRS resource according to the first information.

[0159] Optionally, if the network device does not send the first information to the terminal device, the terminal device determines the bandwidth that can be used to transmit the SRS resource based on the second information. Specifically, the terminal device determines the bandwidth that can be used to transmit the SRS resource based on the c-SRS, b-SRS, b-hop in the second information and the information in Table 2 above.

[0160] Optionally, if the network device sends the first information to the terminal device, the terminal device determines the bandwidth that can be used to transmit the SRS resource based on the second information; the terminal device divides the bandwidth that can be used to transmit the SRS resource into S equal parts based on the first indication information in the first information; the terminal device determines that the target part of the S equal parts is the frequency domain position of the second SRS resource based on the second indication information in the first information.

[0161] Optionally, when the first information is used to indicate the frequency domain position of the second SRS resource, and the target portion is one or more quantities, the second indication information is configured through RRC / MAC CE / DCI signaling.

[0162] (1) The terminal device divides the bandwidth available for transmitting SRS resources into S equal parts according to the first indication information in the first information.

[0163] Exemplarily, the value of the first indication information S in the first information may be determined by the following method:

[0164] 1) A field in the RRC signaling determines that the bandwidth available for transmitting SRS is divided into S equal parts.

[0165] 2) MAC CE / DCI signaling can be used to update a value S configured from RRC signaling, or MAC CE / DCI signaling can be used to select a value S to be used from multiple values ​​configured by RRC signaling.

[0166] (2) The network device instructs the terminal device to transmit the second SRS resource on one or more equal parts of the S segmented bandwidths by configuring the second indication information M in the second information.

[0167] 1) If the second indication information M is not configured, the second SRS resource may be transmitted in all segmented frequency bands.

[0168] 2) The value of M is determined by:

[0169] Method 1: Obtain the quantity from the configuration information of the SRS resource set, RRC / MAC CE / DCI signaling.

[0170] Optionally, the second indication information is configured through a third field in RRC signaling, and the value of the third field Q is [0, S].

[0171] Optionally, the Q is Q segment bandwidths in the frequency domain from small to large among the number of S segment bandwidths, or Q segment bandwidths in the frequency domain from large to small among the number of S segment bandwidths.

[0172] Optionally, MAC CE / DCI signaling may be used to update the number of segment bandwidths Q, or MAC CE / DCI signaling may be used to select the number of segment bandwidths Q to be used from a plurality of values ​​configured by RRC signaling.

[0173] Exemplarily, a field Q is configured in high-level parameters (such as RRC signaling) to indicate the number of second SRS resources that the terminal device can transmit in S segmented bandwidths, where the value of Q is [0, S]. Q is defined as transmitting the second SRS resource in the first Q segmented bandwidths from small to large in the frequency domain, or transmitting the second SRS resource in the first Q segmented bandwidths from large to small in the frequency domain. (Q is different from the definition of Y in Example 1, Q indicates the number, and Y indicates the position).

[0174] Method 2: The second indication information determines the corresponding S segmented bandwidths through a bit map sequence, and determines the Q segmented bandwidth positions for sending the second SRS resource according to the S segmented bandwidths, or the second indication information determines the corresponding S segmented bandwidths through a value of 1 in a bit map sequence, and determines the Q segmented bandwidth positions for sending the second SRS resource according to the S segmented bandwidths.

[0175] Exemplarily, the quantity is obtained from the bitmap sequence in the configuration information RRC / MACCE / DCI signaling; specifically, the terminal device determines the S segmented bandwidths corresponding to the bitmap sequence according to the bitmap sequence contained in the configuration information, thereby determining the Q segmented bandwidth positions for sending the second SRS resource; the terminal device uses the segmented bandwidth corresponding to the position with a value of 1 in the bitmap sequence as the transmission frequency band position of the second SRS resource. For example, the first bit corresponds to the first segmented bandwidth from small to large or from large to small in the frequency domain, and so on.

[0176] Mode 3: The second indication information is determined by a preset function, where the preset function is a function of S and Q, where S is the number of segmented bandwidths of the bandwidth of the SRS resource, and Q is the number of segmented bandwidths for sending the second SRS resource.

[0177] Exemplarily, the number of segmented bandwidths of the SRS resource is S, and the number of sub-band bandwidths that can be used to send the second SRS resource is Q; there is a functional correspondence between S and Q, for example, Q=S / 2 (if S is an odd number, a rounding operation can be performed). And the meaning of Q is to transmit the SRS resource in the first Q segmented bandwidths from small to large in the frequency domain, or to transmit the SRS resource in the first Q segmented bandwidths from large to small in the frequency domain.

In the cross-subband transmission of SRS, a small number of SRS can be used to detect a wider range of bandwidth. It can meet the needs of special circumstances where a small number of SRS is needed to quickly and roughly detect the channel bandwidth within a larger range. And through flexible parameter configuration, the effect of partial frequency hopping can be achieved to achieve the purpose of enhancing coverage and capacity.

Subsequently, the processor 980 provides a corresponding visual output on the display panel 941 according to the type of touch event. Although in Fig. 9 In the embodiment, the touch panel 931 and the display panel 941 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 931 and the display panel 941 can be integrated to realize the input and output functions of the mobile phone.
