Description

[Technical field]

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

[0002] In the related art, a network side device can control a specific operation of SRS transmission by a terminal (also called terminal device or user equipment (UE)) by instructing SRS configuration parameters to the terminal. For semi-persistent SRS or aperiodic SRS, the network side device can also trigger SRS transmission by the UE through trigger signaling.

[0003] The parameters for the semi-persistent SRS may be configured by higher layer signaling (e.g., Radio Resource Control (RRC) signaling), and the terminal can start transmitting the semi-persistent SRS according to the parameters for the SRS configured by the RRC until it receives a deactivation command from the base station. The parameters for the aperiodic SRS are configured by the RRC and trigger a one-time SRS transmission by the terminal in Downlink Control Information (DCI). The RRC configuration parameters include time-domain parameters such as the SRS resource symbol position, the number of Orthogonal frequency division multiplex (OFDM) symbols to occupy, frequency hopping, and a repetition parameter R.

[0004] In the related art, one SRS resource configured for SRS can occupy one, two, or four symbols, and the repetition parameter R can be configured as 1, 2, or 4. The repetition parameter R is for indicating the number of SRS symbols to be transmitted at one time when frequency hopping is configured. For example, when one SRS resource occupies four OFDM symbols, the repetition parameter R=1, and SRS frequency hopping is enabled, the terminal transmits the SRS in the first symbol of one subband, transmits the SRS in the second symbol of another subband, transmits the SRS in the third symbol of yet another subband, and then changes the subband and transmits the SRS in the fourth symbol of the subband. When R=2, the subband is changed every two symbols. When R=4, the SRS is transmitted in four symbols of one subband, and the SRS is transmitted in four symbols even after the subband is changed.

[0005] Therefore, in the related art, the spatial beam used for SRS transmission is not taken into consideration when configuring the SRS configuration parameters. Summary of the Invention [Problem to be solved by the invention]

[0022] Hereinafter, the SRS configuration method provided in the embodiments of the present application will be described in detail in specific embodiments and application scenarios with reference to the drawings.

[0023] FIG. 2 shows a procedure diagram of an SRS configuration method in an embodiment of the present application, and the method 200 may be executed by a network side device. In other words, the method may be executed by software or hardware installed in the network side device. As shown in FIG. 2, the method includes: The method may include step S210 in which the network side device indicates the location parameters of the target SRS to the terminal. The configuration parameters indicate that the SRS resource indicated by the configuration parameters includes N orthogonal frequency division multiplexing OFDM symbols, and frequency hopping of the target SRS is disabled, thereby instructing the terminal to transmit the target SRS in at least one spatial beam in the N OFDM symbols, where N is an integer greater than 1.

[0024] In an embodiment of the present application, a network side device configures a beam management SRS resource for a target SRS of a terminal, where 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 be disabled, it is indicated that the target SRS is transmitted in at least one spatial beam in the SRS resource.

[0025] In one possible implementation, the target SRS includes one of a periodic SRS, a semi-persistent SRS, and an aperiodic SRS, i.e., the time domain characteristic of the SRS resource to be configured may be periodic, semi-persistent, or aperiodic.

[0026] In one possible implementation, when a Repetition parameter in the configuration parameters is set to R, the terminal is instructed to transmit the target SRS using the same spatial beam in every R OFDM symbols among the N OFDM symbols, and to transmit the target SRS using a different spatial beam between every R OFDM symbols, where R is an integer greater than 0 and less than or equal to N.

[0027] In another possible implementation form, for example, when SRS frequency hopping is configured to be disabled, the repetition parameter is pre-promised or specified by a protocol to be invalid, and when the value of the repetition parameter is invalid, R=n is indicated. Or, when the configuration parameters do not include the repetition parameter, R=n. Or, it is pre-promised that the value of the repetition parameter is configured to n, where n is a predetermined value, n is an integer greater than 0 and equal to or less than N, and optionally n may be 1.

[0028] For example, the Repetition parameter R in the placement parameters may be set to any value from 1 to N, for example, the value of R is n. Different values ​​for R can indicate different information, for example: When R=1, the terminal transmits the target SRS on a different beam in each OFDM symbol, ie, transmits the target SRS on N different beams in N OFDM symbols, respectively. For R=2, the terminal transmits the target SRS with the same beam in every second OFDM symbol, transmits the target SRS with a different beam between every second OFDM symbol, and so on for N symbols thereafter, where the symbol indexes in every second OFDM symbol may or may not be consecutive, and consecutive symbol indexes indicate consecutive OFDM symbols in the time domain.

[0029] Similarly, when R=N, the terminal transmits the target SRS using the same beam in N OFDM symbols.

[0030] Alternatively, in another possible implementation form, when a repetition parameter in the configuration parameters is set to valid, the terminal is instructed to transmit the target SRS in the same spatial beam in the N OFDM symbols, and when the repetition parameter in the configuration parameters is set to invalid, the terminal is instructed to transmit the target SRS in a different spatial beam in each OFDM symbol of the N OFDM symbols. In other words, in this possible implementation form, when a repetition parameter in the configuration parameters is set to valid, the terminal is instructed to use the same spatial beam to transmit the target SRS in the N OFDM symbols, and when the repetition parameter is invalid, the terminal is instructed to transmit the target SRS in a different spatial beam in each OFDM symbol of the N OFDM symbols.

[0031] If the target SRS is an aperiodic SRS or a semi-persistent SRS, the network side equipment can send a trigger command of the target SRS to the terminal to trigger the terminal to transmit the target SRS, in which case the network side equipment can include a repetition parameter in the trigger command and send it to the terminal. Thus, in one possible implementation, if the target SRS is an aperiodic SRS or a semi-persistent SRS, the method further includes sending a trigger command of the target SRS to the terminal, and the trigger command includes the repetition parameter.

[0032] In the above possible implementation, optionally, the trigger command is for triggering P transmissions of the target SRS, and in each of the P transmissions of the target SRS, a spatial beam used to transmit the target SRS in the N OFDM symbols is determined according to the repetition parameter, where P is an integer greater than 0. In the alternative implementation, the trigger command can trigger multiple transmissions of the target SRS, and in each transmission, a spatial beam used to transmit the target SRS in the N OFDM symbols is determined by the repetition parameter, specifically, refer to the implementation of the instruction when the repetition parameter is R described above, and detailed description is omitted here.

[0033] For example, for an aperiodic SRS, the trigger command is a command to trigger a terminal to transmit the aperiodic SRS, and the network side device may include a repetition parameter R in the aperiodic SRS trigger command, and the terminal can determine whether to use the same spatial beam or different spatial beams to transmit the target SRS in N OFDM symbols according to the R value indicated in the trigger command. The aperiodic SRS trigger command can also trigger multiple transmissions of the SRS, for example, triggering P transmissions with one DCI signaling, and determining whether to use the same beam for each transmission according to the R value.

[0034] For the semi-persistent SRS, the trigger command is an activation command for activating the semi-persistent SRS configured for the terminal, and the network side device can load a repetition parameter R into the activation command for the semi-persistent SRS, and the terminal can determine whether to use the same beam or different beams to transmit the target SRS in N symbols based on the value of R. In addition, the activation command for the semi-persistent SRS can load the number of transmissions of the target SRS, and instruct the terminal to stop transmission after M transmissions of the target SRS after the target SRS is activated. When this form is adopted, for the semi-persistent SRS, the network side device does not need to send a deactivation command to inform the terminal that the transmission of the target SRS will be stopped, thereby saving signaling overhead. In addition, the spatial beam of the SRS transmission by the terminal can be flexibly configured according to the repetition parameter.

[0035] In one possible implementation, the configuration parameters further include starting positions within one slot of the N OFDM symbols, that is, the network side equipment can configure starting positions within one slot of the SRS resources.

[0036] The terminal may not expect the sum of the starting position and N to be greater than 14, i.e. the length of the symbols to be placed should not exceed the length of the available symbol positions in the slot. Thus, optionally, the sum of M and N is less than or equal to 14 and the starting position is at the Mth OFDM symbol in a slot.

[0037] Alternatively, in one possible implementation, slot spanning may be supported, ie the length of the constrained symbols may be greater than the length of the available symbol positions within the slot.

[0038] For example, the network side device can configure multiple slot time domain positions to determine the first slot and at least one remaining slot position. For periodic and semi-persistent SRS resources, multiple periodic slot offset parameters can be configured, and in this case, it is necessary to ensure that the SRS resources have the same period and different slot offsets. For aperiodic SRS resources, multiple slot offsets can be configured in the aperiodic SRS resource, and no slot offset can be configured or configured in the SRS resource set is ineffective. Alternatively, one slot offset can be configured in the SRS resource set, and the slot time domain position of the resource needs to be determined by the received slot position of the DCI triggering the target SRS, the slot position of the SRS resource set, and the slot position of the SRS resource.

[0039] Alternatively, the network side equipment may configure one slot time domain position to determine the first slot, and obtain at least one remaining slot position by default, for example, the slot next to the first slot or the xth slot, where x is predefined.

[0040] Alternatively, the network side equipment may configure one slot time domain position to determine the first slot, and configure at least one slot offset to indicate a slot difference between each slot.

[0041] Alternatively, the network side equipment may configure one slot time domain position to determine the first slot, and configure at least one symbol offset to indicate a symbol difference between each slot.

[0042] In one possible implementation, the number of spatial beams associated with the SRS resource JPEG0007628176000001.jpg526 That is, in the possible implementation, the number of spatial beam information associated with the SRS resource is equal to N / R or ceiling(N / R) or N. The network side equipment 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, when 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 disabled or equal to 1 by default.

[0043] In one possible implementation form, the network side equipment can indicate the selected uplink spatial beam information of the SRS resource by signaling, for example, the selected uplink spatial beam information of the SRS resource can be indicated by an SRS resource indication field in the DCI signaling.

[0044] In the above possible implementation forms, the uplink spatial beam information indicated by the network side equipment may be spatial relationship information, or may be a transmission configuration indication (TCI), or may be spatial beam identification information, and is not specifically limited in the embodiments of this application.

[0045] In the technical solution provided in the embodiment of the present application, when the frequency hopping of the target SRS is disabled, the repetition parameter in the configuration parameter of the target SRS can trigger the terminal to transmit the target SRS in at least one spatial beam in the SRS resource, and can reduce the control signaling overhead and delay. In addition, the transmission times of the target SRS can be configured in the activation signaling of the semi-persistent SRS, which can further save the signaling overhead, and the repetition parameter can realize the flexible configuration of the SRS transmission beam.

[0046] 3 shows a procedure diagram of an SRS transmission method in an embodiment of the present application, and the method 300 may be performed by a terminal. In other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 3, the method may include the following steps S310 and S312.

[0047] At S310, the terminal receives the configuration parameters of the target SRS.

[0048] The network side device can send the configuration parameters of the target SRS to the terminal according to the manner described in the method 200. For a specific implementation, refer to the description of the method 200, and a detailed description will be omitted here.

[0049] In S312, if the SRS resource indicated by the configuration parameters includes N OFDM symbols and the configuration parameters indicate that frequency hopping of the target SRS is not possible, the terminal transmits the target SRS in at least one spatial beam in the N OFDM symbols, where N is an integer greater than 1.

[0050] In an embodiment of the present application, corresponding to method 200, when a terminal receives configuration parameters of a target SRS transmitted by a network side device in method 200, if the SRS resource indicated by the configuration parameters includes N OFDM symbols and the configuration parameters indicate that frequency hopping of the target SRS is not possible, the terminal transmits the target SRS in at least one spatial beam in the N OFDM symbols.

[0051] In the embodiment of the present application, the target SRS may be a periodic SRS, a semi-persistent SRS or a non-periodic SRS.

[0052] In one possible implementation, when a repetition parameter in the configuration parameters is R, the terminal transmits the target SRS on the same spatial beam in every R OFDM symbols among the N OFDM symbols, and transmits the target SRS on a different spatial beam between every R OFDM symbols, where R is an integer greater than 0 and less than or equal to N. For example, when the number of OFDM symbols occupied by the SRS resource of the target SRS configured in the configuration parameters is N=8 and the repetition parameter R=2, as shown in FIG. 4, the terminal transmits the target SRS on beam 1 in symbols 1 and 2, transmits the target SRS on beam 2 in symbols 3 and 4, transmits the target SRS on beam 3 in symbols 5 and 6, and transmits the target SRS on beam 4 in symbols 7 and 8.

[0053] In this possible implementation, if N is not divisible by R, the last transmitted symbol is less than R. For example, in FIG 5, if N=7 and R=2, the terminal transmits the target SRS on beam 1 in symbols 1 and 2, on beam 2 in symbols 3 and 4, on beam 3 in symbols 5 and 6, and on beam 4 in symbol 7.

[0054] When R=N, the terminal transmits the target SRS using the same spatial beam in N symbols. For example, in FIG. 6, when N=8 and R=8, the terminal transmits the target SRS using beam 1 in all of symbols 1 to 8.

[0055] In one possible implementation, when a repetition parameter in the configuration parameters is configured validly, the terminal transmits the target SRS in the same spatial beam in the N OFDM symbols. For example, assuming N=4, the terminal transmits the target SRS in beam 1 in each of symbols 1 to 4. Alternatively, when a repetition parameter in the configuration parameters is configured invalidly, the terminal transmits the target SRS in a different spatial beam in each OFDM symbol of the N OFDM symbols. For example, assuming N=4, the terminal transmits the target SRS in beam 1 in symbol 1, transmits the target SRS in beam 2 in symbol 2, transmits the target SRS in beam 3 in symbol 3, and transmits the target SRS in beam 4 in symbol 4.

[0056] In another possible implementation form, when the value of the repetition parameter is invalid or the configuration parameters do not include the repetition parameter, R=n, where n is a predetermined value and n is an integer greater than 0 and less than or equal to N. n may be 1 or another predetermined number. Based on a specific value of n, the terminal can transmit the target SRS with the same spatial beam in every nth OFDM symbol among the N OFDM symbols, and transmit the target SRS with different spatial beams between every nth OFDM symbol.

[0057] In one possible implementation, if the target SRS is an aperiodic SRS or a semi-persistent SRS, the terminal receives a trigger command for the target SRS, and the trigger command is loaded with 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 an aperiodic SRS, the trigger command may be a trigger command for triggering transmission of the target SRS by the terminal.

[0058] Optionally, the trigger command may be used to trigger P transmissions of the target SRS, such that, in each of the P transmissions of the target SRS, the terminal determines a spatial beam to use for transmitting the target SRS in the N OFDM symbols according to the repetition parameter, where P is an integer greater than 0.

[0059] For example, the target SRS is a non-periodic SRS, the trigger command triggers P=2 transmissions of the target SRS, and N=8 in the configuration parameters of the target SRS configured by RRC, that is, the number of symbols occupied by one SRS resource of the target SRS is 8. When the repetition parameter R=8, as shown in Figure 7, the spatial beam used for the two target SRS transmissions by the terminal is the same, and 8 symbols are transmitted each time.

[0060] Also for example, the target SRS is a non-periodic SRS, the trigger command triggers P=2 transmissions of the target SRS, and N=8 in the configuration parameters of the target SRS configured by RRC, that is, the number of symbols occupied by one SRS resource of the target SRS is 8. When R=2, as shown in FIG8, the beams for transmitting the target SRS are different every two symbols, and the terminal transmits the target SRS twice, and the symbols and beam orders are the same for the first transmission and the second transmission.

[0061] For example, the target SRS is a semi-persistent SRS, the parameter R=8 loaded in the activation command of the target SRS, and N=8 in the configuration parameters of the target SRS configured by RRC, so that the terminal is instructed to transmit the target SRS with the same beam in all symbols (N=8) occupied by the SRS resource. Also, if the repetition parameter Q=7 loaded in the activation command, as shown in Fig. 9, after the target SRS is activated, the terminal stops transmitting after 7 transmissions, and the network side device does not need to further transmit a deactivation command.

[0062] For example, when the target SRS is a semi-persistent SRS and the parameter R=2 loaded in the activation command of the target SRS instructs the terminal to transmit the target SRS with a different beam every two symbols, N=8 in the configuration parameters of the target SRS configured by RRC, and the repetition parameter Q=7 loaded in the activation command, as shown in FIG. 10, after the target SRS is activated, the terminal stops transmitting after seven transmissions, and the network side equipment does not need to further send a deactivation command.

[0063] In one possible implementation, the placement parameters further comprise a starting position within a slot of the N OFDM symbols, the starting position being intended to indicate a starting OFDM symbol within a slot of N OFDM symbols.

[0064] In one possible implementation, the sum of M and N is less than or equal to 14 and the starting position is at the Mth OFDM symbol within a slot.

[0065] In one possible implementation, the number of spatial beams associated with the SRS resource JPEG0007628176000002.jpg526 It is.

[0066] In one possible implementation, in S312, the step of the terminal transmitting the target SRS on at least one spatial beam in the N OFDM symbols includes: receiving downlink signaling by the terminal, the downlink signaling indicating selected uplink spatial beam information of the SRS resource; The method includes a step of the terminal determining a spatial beam to be used for transmitting the target SRS based on the uplink spatial beam information, and transmitting the target SRS on the determined spatial beam.

[0067] Alternatively, the downlink signaling includes DCI signaling, and the selected uplink spatial beam information of the SRS resource is indicated by an SRS resource indication field in the DCI signaling.

[0068] Optionally, the uplink spatial beam information includes one of spatial relationship information, TCI, and spatial beam identification information.

[0069] It should be noted that the execution entity of the SRS configuration method provided in the embodiment of the present application may be an SRS configuration device, or may be a control module for executing the SRS configuration method in the SRS configuration device. In the embodiment of the present application, the SRS configuration device provided in the embodiment of the present application will be described by taking the SRS configuration device executing the SRS configuration method as an example.

[0070] FIG. 11 shows a structural schematic diagram of an SRS configuration device provided in an embodiment of the present application. As shown in FIG. 11, the device 1100 may include: a determining module 1101 and a first sending module 1102 .

[0071] In an embodiment of the present application, the determination module 1101 is used to determine the configuration parameters of a target SRS of a terminal, the first transmission module 1102 is used to indicate the configuration parameters of the target SRS to the terminal, the SRS resource indicated by the configuration parameters includes N OFDM symbols, and the configuration parameters indicate that frequency hopping of the target SRS is not possible, thereby instructing the terminal to transmit the target SRS in at least one spatial beam in the N OFDM symbols, where N is an integer greater than 1.

[0072] In one possible implementation, the target SRS includes one of a periodic SRS, a semi-persistent SRS, and an aperiodic SRS.

[0073] In one possible implementation, when a repetition parameter in the configuration parameters is R, the terminal is instructed to transmit the target SRS using the same spatial beam in every R OFDM symbols among the N OFDM symbols, and to transmit the target SRS using a different spatial beam between every R OFDM symbols, where R is an integer greater than 0 and less than or equal to N.
