Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a sounding reference signal (SRS) configuration method, a terminal, and a network side device. Background Art

[0002] In the related technology, the network side device can indicate SRS configuration parameters for the terminal (also referred to as terminal device or user equipment (UE)) to control the specific behavior of the terminal sending SRS. For semi-persistent SRS or non-periodic SRS, the network side device can also trigger the UE to send SRS through trigger signaling.

[0003] Among them, the relevant parameters of semi-persistent SRS can be configured by high-level signaling (for example, Radio Resource Control (RRC) signaling), and the terminal can start sending semi-persistent SRS according to the relevant parameters of SRS configured by RRC until the terminal receives the deactivation command from the base station. The relevant parameters of aperiodic SRS are configured by RRC, triggering the terminal to send a single SRS in the downlink control information (Downlink Control Information, DCI). RRC configuration parameters include time domain parameters such as SRS resource symbol position, number of occupied orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbols, frequency hopping, repetition parameter R, etc.

[0004] In the related art, an SRS resource configured for SRS can occupy 1, 2, or 4 symbols, and the repetition parameter R can be configured as 1, 2, or 4. The repetition parameter R is used to indicate the number of SRS symbols sent at one time when frequency hopping is configured. For example: an SRS resource occupies 4 OFDM symbols, repetition parameter R=1, and SRS frequency hopping is enabled; when the terminal sends SRS in a frequency hopping manner, it sends SRS on the first symbol of a subband, the second symbol of another subband, and then the third symbol of another subband, and then changes a subband and sends SRS on the fourth symbol of the subband. If R=2, a subband is changed every 2 symbols; if R=4, SRS is sent on 4 symbols of a subband, a subband is changed, or 4 symbols are sent.

[0005] It can be seen that in the related art, when configuring SRS parameters, the spatial beam used for sending SRS is not considered. Summary of the invention

[0036] The SRS configuration method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0037] Figure 2 A flow chart of the SRS configuration method in the embodiment of the present application is shown. The method 200 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Figure 2 As shown, the method may include the following steps.

[0038] S210: The network-side device indicates configuration parameters of the target SRS to the terminal.

[0039] Among them, the SRS resources indicated by the configuration parameters include N orthogonal frequency division multiplexing OFDM symbols, and the configuration parameters indicate that the frequency hopping of the target SRS is not enabled, then the terminal is instructed to use at least one spatial beam on the N OFDM symbols to send the target SRS, and N is an integer greater than 1.

[0040] In an embodiment of the present application, the network side device configures a beam management SRS resource for the target SRS of the terminal. The SRS resource occupies N symbols. When N is an integer greater than 1 and the frequency hopping of the target SRS is configured to disable, it indicates that the target SRS is sent on the SRS resource using at least one spatial beam.

[0041] In a possible implementation, the target SRS includes one of the following: a periodic SRS, a semi-persistent SRS, and an aperiodic SRS. That is, the time domain characteristic of the configured SRS resource may be periodic, semi-persistent, or aperiodic.

[0042] In one possible implementation, if the repetition parameter in the configuration parameters is configured to R, it indicates that the terminal uses the same spatial beam to send the target SRS on each R OFDM symbols among the N OFDM symbols, and uses different spatial beams to send the target SRS between each R OFDM symbols, where R is an integer greater than 0 and less than or equal to N.

[0043] In another possible implementation, if the value of the repetition parameter is not effective, for example, it is pre-agreed or stipulated in the protocol that the repetition parameter is not effective when the SRS frequency hopping configuration is disabled, then R=n is indicated; or, if the configuration parameters do not include the repetition parameter, then R=n; or, it is pre-agreed that the value of the repetition parameter is configured as n. Wherein, n is a predetermined value, and n is an integer greater than 0 and less than or equal to N; optionally, n can be 1.

[0044] For example, the Repetition parameter R in the configuration parameters can be configured to any value from 1 to N. If the value of R is n, then:

[0045] When R=1, the terminal uses different beams to send the target SRS in each OFDM symbol, that is, N different beams are used to send the target SRS in N OFDM symbols;

[0046] When R=2, the terminal uses the same beam to send the target SRS in every 2 OFDM symbols, uses different beams to send the target SRS between every 2 OFDM symbols, and so on to send the target SRS in N symbols. At this time, the symbol indexes in every 2 OFDM symbols can be continuous or discontinuous. The continuous symbol index indicates continuous OFDM symbols in the time domain.

[0047] By analogy, when R=N, the terminal uses the same beam to send the target SRS in N OFDM symbols.

[0048] Alternatively, in another possible implementation, if the repetition parameter in the configuration parameter is configured to be effective, the terminal is instructed to use the same spatial beam to send the target SRS on the N OFDM symbols; if the repetition parameter in the configuration parameter is configured to be ineffective, the terminal is instructed to use different spatial beams to send the target SRS on each OFDM symbol of the N OFDM symbols. That is, in this possible implementation, if the repetition parameter in the configuration parameter is configured to be effective, the terminal is instructed to use the same spatial beam to send the target SRS on N OFDM symbols; if it is ineffective, the terminal is instructed to use different spatial beams to send the target SRS on each OFDM symbol of the N OFDM symbols.

[0049] If the target SRS is an aperiodic SRS or a semi-persistent SRS, the network side device may send a trigger command of the target SRS to the terminal to trigger the terminal to send the target SRS. In this case, the network side device may carry a repetition parameter in the trigger command and send it to the terminal. Therefore, in a possible implementation, the method further includes: if the target SRS is an aperiodic SRS or a semi-persistent SRS, sending a trigger command of the target SRS to the terminal, wherein the trigger command carries the repetition parameter.

[0050] In the above possible implementations, optionally, the trigger command is used to trigger P transmissions of the target SRS, wherein, for each of the P transmissions of the target SRS, the spatial beam used to send the target SRS on the N OFDM symbols is determined according to the repetition parameter, and P is an integer greater than 0. In this optional implementation, the trigger command may trigger multiple transmissions of the target SRS, wherein, in each transmission, the spatial beam used to send the target SRS on N OFDM symbols is determined by the repetition parameter, and details may be referred to the implementation indicated when the repetition parameter is R, which will not be repeated here.

[0051] For example, for aperiodic SRS, the trigger command is a command to trigger the terminal to send the aperiodic SRS. The network side device can carry the repetition parameter R in the trigger command of the aperiodic SRS. The terminal can determine whether to use the same or different spatial beams to send the target SRS on N OFDM symbols according to the R value indicated by the trigger command. In addition, the trigger command of the aperiodic SRS can also trigger multiple transmissions of SRS. For example, a DCI signaling triggers P transmissions and determines whether to use the same beam for each transmission according to the R value.

[0052] For semi-persistent SRS, the trigger command is an activation command for activating the semi-persistent SRS configured for the terminal. The network-side device can carry the repetition parameter R in the activation command of the semi-persistent SRS, and the terminal can determine whether to use the same or different beams to send the target SRS in N symbols based on the R value. In addition, the activation command of the semi-persistent SRS can also carry the number of target SRS transmissions, instructing the terminal to stop sending the target SRS after M times after the target SRS is activated. In this way, for semi-persistent SRS, the network-side device does not need to send a deactivation command to notify the terminal to stop sending the target SRS, thereby saving signaling overhead. In addition, the spatial beam for the terminal to send SRS can be flexibly configured through the repetition parameter.

[0053] In a possible implementation, the configuration parameter further includes the starting position of the N OFDM symbols in a time slot, that is, the network side device may configure the starting position of the SRS resource in a time slot.

[0054] The terminal may not expect the sum of the starting position and N to be greater than 14, that is, the configured symbol length should not exceed the available symbol position length in the time slot. Therefore, optionally, the sum of M and N is less than or equal to 14, where the starting position is located at the Mth OFDM symbol in a time slot.

[0055] Alternatively, in a possible implementation, cross-time slot configuration may also be supported, that is, the configured symbol length is allowed to be greater than the available symbol position length in the time slot.

[0056] For example, the network side device can configure multiple time slot time domain positions for determining the first time slot and at least one other time slot position. Among them, for periodic and semi-continuous SRS resources, multiple periodic time slot offset parameters can be configured. In this case, it is necessary to ensure that the SRS resources have the same period, but the time slot offsets are different; for non-periodic SRS resources, multiple time slot offsets can be configured in the non-periodic SRS resources, and the time slot offset is not configured in the SRS resource set or is not effective if configured, or a time slot offset is configured in the SRS resource set, and the time slot time domain position of the resource needs to be determined by the receiving time slot position of the DCI that triggers the target SRS, the time slot position of the SRS resource set, and the time slot position of the SRS resource.

[0057] Alternatively, the network side device may also configure one time slot time domain position to determine the first time slot, and the remaining at least one time slot position is obtained by default. For example, the next time slot of the first time slot, or the xth time slot, x is predefined

[0058] Alternatively, the network side device may also configure one time slot time domain position for determining the first time slot, and configure at least one time slot offset for indicating the time slot difference between each time slot.

[0059] Alternatively, the network side device may further configure one time slot time domain position for determining the first time slot, and configure at least one symbol offset for indicating the symbol difference between each time slot.

[0060] In a possible implementation, the number of spatial beams associated with the SRS resource is That is, in this possible implementation, the number of spatial beam information associated with the SRS resource is equal to N / R or rounded up (N / R) or equal to N. The network side device can configure the number of spatial beam information associated with the SRS resource and the value of the repetition parameter according to specific needs. For example, if the number of spatial beam information associated with the SRS resource is equal to N, the repetition parameter R=1, or the repetition parameter is not effective, or is equal to 1 by default.

[0061] In a possible implementation, the network-side device may indicate the uplink spatial beam information selected by the SRS resource through signaling. For example, the uplink spatial beam information selected by the SRS resource may be indicated through an SRS resource indication field in the DCI signaling.

[0062] In the above possible implementation methods, the uplink spatial beam information indicated by the network side device may be spatial relationship information, or a transmission configuration indication (TCI), or identification information of the spatial beam, which is not limited in the specific embodiments of the present application.

[0063] In the technical solution provided in the embodiment of the present application, when the frequency hopping of the target SRS is not enabled, the repetition parameter in the configuration parameter of the target SRS can be used to trigger the terminal to use at least one spatial beam to send the target SRS on the SRS resource, which can reduce the control signaling overhead and delay. In addition, by configuring the number of transmissions of the target SRS in the activation signaling of the semi-persistent SRS, the signaling overhead can be further saved, and the flexible configuration of the SRS transmission beam can be achieved through the repetition parameter.

[0064] Figure 3 1 is a flow chart showing a method for sending an SRS in an embodiment of the present application. The method 300 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 3 As shown, the method may include the following steps.

[0065] S310: The terminal receives configuration parameters of a target SRS.

[0066] The network side device may send the configuration parameters of the target SRS to the terminal in the manner described in method 200. The specific implementation manner may refer to the description in method 200 and will not be described in detail here.

[0067] S312: If the SRS resources indicated by the configuration parameters include N OFDM symbols, and the configuration parameters indicate that frequency hopping of the target SRS is disabled, the terminal uses at least one spatial beam on the N OFDM symbols to send the target SRS, where N is an integer greater than 1.

[0068] In an embodiment of the present application, corresponding to method 200, when the terminal receives the configuration parameters of the target SRS sent by the network side device using method 200, if the SRS resources indicated by the configuration parameters include N OFDM symbols, and the configuration parameters indicate that the frequency hopping of the target SRS is not enabled, then the terminal uses at least one spatial beam on the N OFDM symbols to send the target SRS.

[0069] In the embodiment of the present application, the target SRS may be a periodic SRS, a semi-persistent SRS or an aperiodic SRS.

[0070] In a possible implementation, if the repetition parameter in the configuration parameter is R, the terminal uses the same spatial beam to send the target SRS in each R OFDM symbols among the N OFDM symbols, and uses different spatial beams to send the target SRS between each R OFDM symbols, where R is an integer greater than 0 and less than or equal to N. For example, if the SRS resource of the target SRS configured by the configuration parameter occupies the number of OFDM symbols N=8, and the repetition parameter R=2, then Figure 4 As shown, the terminal sends the target SRS using beam one in symbols 1 and 2, sends the target SRS using beam two in symbols 3 and 4, sends the target SRS using beam three in symbols 5 and 6, and sends the target SRS using beam four in symbols 7 and 8.

[0071] In this possible implementation, if N is not divisible by R, the last transmitted symbol is less than R. For example, Figure 5 In the example, N=7, R=2, the terminal sends the target SRS with beam one in symbols 1 and 2, sends the target SRS with beam two in symbols 3 and 4, sends the target SRS with beam three in symbols 5 and 6, and sends the target SRS with beam four in symbol 7.

[0072] If R = N, the terminal uses the same spatial beam to send the target SRS on N symbols. Figure 6 In the example, N=8, R=8, the terminal uses beam 1 to send the target SRS on symbols 1 to 8.

[0073] In a possible implementation, if the repetition parameter in the configuration parameter is configured to be effective, the terminal uses the same spatial beam to send the target SRS on the N OFDM symbols; for example, assuming N=4, the terminal uses beam one to send the target SRS on symbols 1 to 4. Alternatively, if the repetition parameter in the configuration parameter is configured to be ineffective, the terminal uses a different spatial beam to send the target SRS on each OFDM symbol of the N OFDM symbols. For example, assuming N=4, the terminal sends the target SRS on symbol 1 using beam one, sends the target SRS on symbol 2 using beam two, sends the target SRS on symbol 3 using beam three, and sends the target SRS on symbol 4 using beam four.

[0074] In another possible implementation, if the value of the repetition parameter is not effective, or the configuration parameter does not include the repetition parameter, then R=n, where n is a predetermined value, and n is an integer greater than 0 and less than or equal to N. Where n can be 1 or other predetermined numbers, the terminal can use the same spatial beam in every n OFDM symbols in the N OFDM symbols to send the target SRS, and use different spatial beams between every n OFDM symbols to send the target SRS according to the specific value of n.

[0075] In one possible implementation, if the target SRS is a non-periodic SRS or a semi-persistent SRS, the terminal receives a trigger command for the target SRS, wherein the trigger command carries the repetition parameter. If the target SRS is a semi-persistent SRS, the trigger command may be an activation command for activating the target SRS configuration, and if the target SRS is a non-periodic SRS, the trigger command may be a trigger command for triggering the terminal to send the target SRS.

[0076] Optionally, the trigger command can be used to trigger P transmissions of the target SRS, wherein the terminal determines the spatial beam used to send the target SRS on the N OFDM symbols according to the repetition parameter for each of the P transmissions of the target SRS, and P is an integer greater than 0.

[0077] For example, the target SRS is a non-periodic SRS, the trigger command triggers P = 2 times of sending the target SRS, and the configuration parameter of the target SRS configured by RRC is N = 8, that is, the number of symbols occupied by one SRS resource of the target SRS is 8. If the repetition parameter R = 8, then Figure 7 As shown, the terminal uses the same spatial beam to send the target SRS twice, and sends 8 symbols each time.

[0078] For another example, the target SRS is a non-periodic SRS, the trigger command triggers P=2 target SRS transmissions, and the configuration parameters of the target SRS configured by RRC are N=8, that is, the number of symbols occupied by one SRS resource of the target SRS is 8. If R=2, then Figure 8 As shown, the beams for sending the target SRS every 2 symbols are different, the terminal sends the target SRS twice, and the symbols and beams for the first and second transmissions are in the same order.

[0079] For another example, the target SRS is a semi-persistent SRS, the parameter R carried in the activation command of the target SRS is 8, and the configuration parameter N of the target SRS configured by RRC is 8, which indicates that the terminal uses the same beam to send the target SRS when the SRS resource occupies all symbols (N=8). In addition, the repetition parameter Q carried in the activation command is 7, so Fig. 9 As shown, after the target SRS is activated, the terminal stops sending after sending 7 times, and the network side device does not need to send a deactivation command again.

[0080] For another example, the target SRS is a semi-persistent SRS, the parameter R carried in the activation command of the target SRS is 2, indicating that the terminal uses different beams to send the target SRS every 2 symbols, the configuration parameter N of the target SRS configured by RRC is 8, and the repetition parameter Q carried in the activation command is 7. Fig.10As shown, after the target SRS is activated, the terminal stops sending after sending 7 times, and the network side device does not need to send a deactivation command again.

[0081] In a possible implementation, the configuration parameter further includes a starting position of the N OFDM symbols in a time slot. The starting position is used to indicate a starting OFDM symbol of the N OFDM symbols in a time slot.

[0082] In a possible implementation, the sum of M and N is less than or equal to 14, wherein the starting position is located at the Mth OFDM symbol in a time slot.

[0083] In a possible implementation, the number of spatial beams associated with the SRS resource is

[0084] In a possible implementation, in S312, the terminal uses at least one spatial beam on the N OFDM symbols to send the target SRS, including:

[0085] The terminal receives downlink signaling, wherein the downlink signaling indicates uplink spatial beam information selected by the SRS resource;

[0086] The terminal determines a spatial beam used to send the target SRS according to the uplink spatial beam information, and sends the target SRS using the determined spatial beam.

[0087] Optionally, the downlink signaling includes: DCI signaling, wherein an SRS resource indication field in the DCI signaling indicates uplink spatial beam information selected by the SRS resource.

[0088] Optionally, the uplink spatial beam information includes one of the following: spatial relationship information, TCI, and identification information of the spatial beam.

[0089] It should be noted that the SRS configuration method provided in the embodiment of the present application can be executed by an SRS configuration device, or a control module in the SRS configuration device for executing the SRS configuration method. In the embodiment of the present application, the method of executing the SRS configuration by the SRS configuration device is taken as an example to illustrate the SRS configuration device provided in the embodiment of the present application.

[0090] Fig.11 A schematic diagram of the structure of the SRS configuration device provided in an embodiment of the present application is shown as follows: Fig.11 As shown, the device 1100 may include: a determination module 1101 and a first sending module 1102 .

[0091] In an embodiment of the present application, a determination module 1101 is used to determine the configuration parameters of the target SRS of the terminal; a first sending module 1102 is used to indicate the configuration parameters of the target SRS to the terminal; wherein, the SRS resources indicated by the configuration parameters include N OFDM symbols, and the configuration parameters indicate that the frequency hopping of the target SRS is not enabled, then the terminal is instructed to use at least one spatial beam on the N OFDM symbols to send the target SRS, and N is an integer greater than 1.

[0092] In a possible implementation manner, the target SRS includes one of the following: a periodic SRS, a semi-persistent SRS, and an aperiodic SRS.
