[0021] The present application will now be described in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0022] In this application embodiment, an indication method is provided. By uniformly setting the bit width of the SOI field of each indication unit, the bits in the SOI field corresponding to one indication unit can be used to indicate other indication units, thereby realizing cross-indication of SRS transmission time slots and improving the reliability and flexibility of reference signal transmission time slot indication.

[0023] Figure 1 This is a flowchart illustrating an indication method according to one embodiment. The method can be applied to a first communication node, such as a network-side device like a base station. Figure 1As shown, the method provided in this embodiment includes steps 110 and 120.

[0024] In step 110, the bit width of the slot offset indication SOI field is determined based on the number of slot indication parameters configured in the reference signal resource set of the indication unit.

[0025] In step 120, downlink control information (DCI) is sent, the DCI including the SOI field.

[0026] In this embodiment, the indicating unit is the unit that indicates the SRS transmission slot, which can be a CC or a BWP. The reference signal mainly refers to the aperiodic SRS. The SOI field in the DCI is used to instruct the second communication node (e.g., a terminal) to transmit the reference signal in the (t+1)th available slot, where t is a slot indication parameter, which is a key parameter used to determine the transmission of the reference signal. The reference point for counting the (t+1)th available slot can be slot n or slot n+k, where slot n is the slot in which the second communication node receives the DCI that triggers the reference signal, and k is a slot offset parameter configured by the higher-layer Radio Resource Control (RRC) parameter (slotOffset).

[0027] In this embodiment, each indicator unit's reference signal resource set may be configured with multiple time slot indication parameters t, for example, three CCs, denoted as CC 0, CC 1, and CC 2. The number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2. Based on the number of time slot indication parameters configured in the reference signal resource set of each indicator unit, the bit width of the SOI field can be determined. For example, for CC 0, if two t values ​​are configured, the bit width of the SOI field can be log22, meaning that 1 bit is sufficient to indicate which t value is used. Furthermore, to ensure that the SOI field corresponding to CC 0 has enough bits to indicate the t value of CC 1, the SOI field of CC 0 can be extended to 2 bits, thereby indicating which of the four configured t values ​​CC 1 should use.

[0028] Based on the above, the first communication node can uniformly configure the bit width of the SOI field of each indicator unit, which can realize cross-indicator indication of the SRS transmission time slot, and improve the reliability and flexibility of the reference signal transmission time slot indication.

[0029] In one embodiment, determining the bit width of the slot offset indication field (SOI) based on the number of slot indication parameters configured in the reference signal resource set of all indication units includes: determining the bit width of the SOI field corresponding to each indication unit based on the maximum value among the number of slot indication parameters configured in the reference signal resource set of all indication units; wherein the bit width of the SOI field corresponding to each indication unit is the same.

[0030] In this embodiment, the bit width of the SOI field corresponding to each indicator unit is the same, and this bit width depends on the maximum value among the number of time slot indication parameters configured in the reference signal resource set of each indicator unit. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2. Among them, the maximum number of t values ​​configured in the aperiodic SRS resource set is 4. Then, the bit width of the SOI field corresponding to each CC is log24, which is 2.

[0031] Similarly, if in a CC, the number of t values ​​configured in the aperiodic SRS resource set on CC 0 of BWP 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on BWP 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on BWP 2 is 2, where the maximum number of t values ​​configured in the aperiodic SRS resource set is 4, then the bit width of the SOI field corresponding to each BWP is log24 = 2.

[0032] In one embodiment, the indication unit includes a first indication unit and a second indication unit, wherein the first indication unit includes an indication unit whose number of time slot indication parameters configured in the reference signal resource set is less than the maximum value, and the second indication unit includes an indication unit whose number of time slot indication parameters configured in the reference signal resource set is equal to the maximum value; all or part of the bits in the SOI field corresponding to the first indication unit are used to indicate the value of the time slot indication parameter in the reference signal resource set of the second indication unit, or to select the time slot indication parameter in the reference signal resource set of the second indication unit.

[0033] In this embodiment, the bit width of the SOI field corresponding to each indicator unit is the same, and this bit width depends on the maximum value among the number of time slot indication parameters configured in the reference signal resource set of each indicator unit. The indicator units are divided into two categories: one is the first indicator unit, where the number of time slot indication parameters configured in the reference signal resource set of the first indicator unit is the maximum value among the number of time slot indication parameters corresponding to each indicator unit. In other words, the bit width of the SOI field corresponding to the first indicator unit is determined by the number of time slot indication parameters configured in its own reference signal resource set. The other category is the second indicator unit, where the number of time slot indication parameters configured in the reference signal resource set of the second indicator unit is not the maximum value among the number of time slot indication parameters corresponding to each indicator unit. In other words, the bit width of the SOI field corresponding to the second indicator unit is determined by the number of time slot indication parameters configured in the reference signal resource sets of the other indicator units. For example, if the number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2, then CC 0 and CC 2 are both first indicator units, and CC 1 is a second indicator unit.

[0034] In this embodiment, the indication of the time slot indication parameter t within the first indication unit can be achieved by using a portion of the bits in the SOI field corresponding to the first indication unit to indicate the value of the time slot indication parameter in its own reference signal resource set, or by selecting the time slot indication parameter in its own reference signal resource set. For example, for the SOI field on CC 0 (bit width of 2 bits), the high 1 bit or the low 1 bit can be used to indicate or select the value of t on CC 0; for the SOI field on CC 2 (bit width of 2 bits), the high 1 bit or the low 1 bit can be used to indicate or select the value of t on CC 2.

[0035] In this embodiment, for the indication of the time slot indication parameter t across indication units, all or part of the bits in the SOI field corresponding to the first indication unit can be used to indicate the value of the time slot indication parameter in the reference signal resource set of the second indication unit, or to select the time slot indication parameter in the reference signal resource set of the second indication unit. For example, if the SOI field on CC 0 is used to indicate or select the value of t on CC 1, then all bits (2 bits) of the SOI field of CC 0 can be used to indicate or select the value of t on CC 1, for a total of four indications or selections; or part of the bits (1 bit, which can be a high bit or a low bit) of the SOI field of CC 0 can be used to indicate or select the value of t on CC 1, for a total of two indications or selections. It should be noted that the above example also applies to multiple BWPs in CC.

[0036] In one embodiment, the indication unit includes a first indication unit and a second indication unit, wherein the first indication unit includes an indication unit whose number of time slot indication parameters configured in the reference signal resource set is less than the maximum value, and the second indication unit includes an indication unit whose number of time slot indication parameters configured in the reference signal resource set is equal to the maximum value; a portion of the bits in the SOI field corresponding to the second indication unit is used to indicate the value of the time slot indication parameter in the reference signal resource set of the first indication unit, or to select the time slot indication parameter in the reference signal resource set of the first indication unit.

[0037] In this embodiment, the bit width of the SOI field corresponding to each indication unit is the same, and this bit width depends on the maximum value among the number of time slot indication parameters configured in the reference signal resource set of each indication unit. The indication units are divided into two categories. For example, if the number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2, then CC 0 and CC 2 are both first indication units, and CC 1 is a second indication unit.

[0038] In this embodiment, for the indication of the time slot indication parameter t across indication units, a portion of the bits in the SOI field corresponding to the second indication unit can be used to indicate the value of the time slot indication parameter in the reference signal resource set of the first indication unit, or to select the time slot indication parameter in the reference signal resource set of the first indication unit. For example, using the SOI field on CC 1 to indicate or select the t value on CC 0 or CC 2, the high 1 bit or low 1 bit of the SOI field on CC 1 can be used to indicate or select the value of t on CC 0 or CC 2, thereby realizing the indication across time domain units. It should be noted that the above example also applies to multiple BWPs in CC.

[0039] In one embodiment, determining the bit width of the slot offset indication field (SOI) based on the number of slot indication parameters configured in the reference signal resource set of the indication unit includes: determining the bit width of the SOI field corresponding to each indication unit based on the number of slot indication parameters configured in the reference signal resource set of each indication unit.

[0040] In this embodiment, the bit width of the SOI field corresponding to each indicator unit may be different. The bit width of the SOI field corresponding to each indicator unit depends on the number of time slot indication parameters configured in the reference signal resource set of that indicator unit. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2. Then the SOI bit width on CC 0 is log22 = 1, the SOI bit width on CC 1 is log24 = 2, and the SOI bit width on CC 2 is log22 = 1. It should be noted that the above example also applies to multiple BWPs in CC.

[0041] In one embodiment, the indication unit includes a third indication unit and a fourth indication unit, wherein the number of time slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of time slot indication parameters configured in the reference signal resource set of the fourth indication unit; a portion of the bits in the SOI field corresponding to the fourth indication unit are used to indicate the value of the time slot indication parameter in the reference signal resource set of the third indication unit, or to select the time slot indication parameter in the reference signal resource set of the third indication unit.

[0042] In this embodiment, the bit width of the SOI field corresponding to each indicator unit depends on the number of time slot indication parameters configured in the reference signal resource set of that indicator unit. The indicator units are divided into two categories: third indicator units and fourth indicator units. The number of time slot indication parameters configured in the reference signal resource set of the third indicator unit is less than the number of time slot indication parameters configured in the reference signal resource set of the fourth indicator unit. That is, the bit width of the SOI field corresponding to the third indicator unit is less than the bit width of the SOI field corresponding to the fourth indicator unit. For example, if the number of t values ​​configured in the aperiodic SRS resource set on CC 0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC 1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC 2 is 2, then CC 0 and CC 2 are both third indicator units, and CC 1 is a fourth indicator unit.

[0043] In this embodiment, for the indication of the time slot indication parameter t across indication units, a portion of the bits in the SOI field corresponding to the fourth indication unit can be used to indicate or select the value of the time slot indication parameter in the reference signal resource set of the third indication unit. For example, the high 1 bit or low 1 bit in the 2-bit SOI field on CC 1 can be used to indicate or select the t value on CC 0 or CC 2. It should be noted that the above example also applies to multiple BWPs in CC.

[0044] In one embodiment, the indication unit includes a third indication unit and a fourth indication unit, wherein the number of time slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of time slot indication parameters configured in the reference signal resource set of the fourth indication unit; after the high or low bits of the SOI field corresponding to the third indication unit are filled with 0 or 1, it is used to indicate the value of the time slot indication parameter in the reference signal resource set of the fourth indication unit, or to select the time slot indication parameter in the reference signal resource set of the fourth indication unit; wherein the size of the field after the high or low bits of the SOI field corresponding to the third indication unit are filled with 0 or 1 is equal to the size of the SOI field corresponding to the fourth indication unit.

[0045] In this embodiment, the bit width of the SOI field corresponding to each indicator unit depends on the number of time slot indication parameters configured in the reference signal resource set of that indicator unit. The indicator units are divided into two categories: a third indicator unit and a fourth indicator unit. The number of time slot indication parameters configured in the reference signal resource set of the third indicator unit is less than the number of time slot indication parameters configured in the reference signal resource set of the fourth indicator unit.

[0046] For indicating the time slot indication parameter t across indication units, 0 or 1 can be filled in the high or low bits of the SOI field corresponding to the third indication unit to make its bit width equal to the bit width of the SOI field corresponding to the fourth indication unit. This bit is then used to indicate or select the value of the time slot indication parameter in the reference signal resource set of the fourth indication unit. For example, using a 1-bit SOI field on CC 0 or CC 2 to indicate the value of t on CC 1 across CC, 0 or 1 can be filled in the high or low bits of the SOI field on CC 0 or CC 2 to make its bit width the same as the SOI field bit width on CC 1. The filled SOI field then indicates the value of t on CC 1. The filled bit, combined with the original bit (a total of 2 bits), can indicate a maximum of 2... 2 = 4 possible values ​​for t. It should be noted that the above example also applies to multiple BWPs in CC.

[0047] In one embodiment, the DCI format corresponding to the reference signal resource set is not DCI 2-3.

[0048] In this embodiment, the DCI format can be any format other than DCI 2-3. If the DCI format is DCI 2-3, that is, the reference signal resource set is the resource set used or associated with DCI 2-3, then the configuration of t is ignored.

[0049] In one embodiment, the indication unit includes a member carrier (CC) and / or a bandwidth portion (BWP).

[0050] In one embodiment, the SOI field is used to indicate the value of a time slot indication parameter in the reference signal resource set of the terminal, or to select a time slot indication parameter in the reference signal resource set of the terminal; the reference signal includes SRS;

[0051] When the terminal is configured with the carrier aggregation-slot offset parameter (ca-SlotOffset), it can transmit reference signals in the reference signal resource set of each triggered indication unit on the (t+1)th available time slot, based on the t value indicated by the SOI field in the received DCI. The reference signal mainly refers to the SRS, and the available time slots are calculated starting from the following time slots:

[0052] or

[0053]

[0054] Without being configured with carrier aggregation-slot offset parameters, the terminal can transmit reference signals in the reference signal resource set of each triggered indication unit on the (t+1)th available slot, based on the t value indicated by the SOI field in the received DCI. The available slots are calculated starting from the following slots:

[0055] or

[0056] Where t is the slot indication parameter, n is the slot index of the received DCI, k is the slot offset parameter configured by the higher layer parameters for the SRS resource set of each triggered indication unit, and k is associated with the subcarrier spacing that triggered the SRS transmission, μ SRS For the subcarrier spacing configuration of the triggered SRS, μ PDCCH Configure the subcarrier spacing for the Physical Downlink Control Channel (PDCCH) carrying trigger commands. The carrier aggregation-slot offset parameter is the slot offset between the primary and secondary cells configured for the cell receiving the PDCCH, or the slot offset between the primary and secondary cells, μ. offset,PDCCH Configure the minimum carrier spacing (i.e., the maximum value of the minimum carrier spacing configuration) among the subcarrier spacings configured for cells receiving PDCCH, as specified by the higher-layer parameters. The carrier aggregation-slot offset parameter is the slot offset between the primary and secondary cells configured for the cell transmitting SRS, or the slot offset between the primary and secondary cells. μoffset,SRS is the maximum minimum carrier spacing configuration (i.e., the maximum value of the minimum carrier spacing configuration) among the subcarrier spacings configured for the cell transmitting SRS by the higher layer parameter.

[0057] Based on this, regardless of whether the terminal is configured with carrier aggregation-slot offset parameters, the reference signal can be accurately transmitted according to the indication of the SOI field, improving the flexibility and reliability of reference signal transmission. It should be noted that in this embodiment, the UE receives the DCI that triggers aperiodic SRS on slot n, excluding the case where the SRS is configured with the higher-layer parameter SRS-PosResource-r16. In one embodiment, the SOI field is used to indicate the value of the slot indication parameter in the terminal's reference signal resource set, or to select the slot indication parameter in the terminal's reference signal resource set; the reference signal includes SRS.

[0058] When the terminal is configured with carrier aggregation-slot offset parameters, it can transmit reference signals in the reference signal resource set of each triggered indication unit on the following slots, based on the t value indicated by the SOI field in the received DCI:

[0059] or

[0060]

[0061] Without configuring carrier aggregation-slot offset parameters, the terminal transmits the reference signal in the reference signal resource set of each triggered indication unit on the following slots:

[0062] or

[0063] Where t is the slot indication parameter, n is the slot index of the received DCI, k is the slot offset parameter configured by the higher layer for each triggered SRS resource set, and k is associated with the subcarrier spacing that triggered the SRS transmission, μ SRS For the subcarrier spacing configuration of the triggered SRS, μ PDCCH Configure the subcarrier spacing for the Physical Downlink Control Channel (PDCCH) carrying trigger commands. The carrier aggregation-slot offset parameter is the slot offset between the primary and secondary cells configured for the cell receiving the PDCCH, or the slot offset between the primary and secondary cells, μ. offset,PDCCH Configure the minimum carrier spacing (i.e., the maximum value of the minimum carrier spacing configuration) among the subcarrier spacings configured for cells receiving PDCCH, as specified by the higher-layer parameters. The carrier aggregation-slot offset parameter is the slot offset between the primary and secondary cells configured for the cell transmitting SRS, or the slot offset between the primary and secondary cells. μoffset,SRS is the maximum minimum carrier spacing configuration (i.e., the maximum value of the minimum carrier spacing configuration) among the subcarrier spacings configured for the cell transmitting SRS by the higher layer parameter.

[0064] In this application embodiment, a reference signal transmission method is also provided, which can accurately transmit SRS for each indicator unit according to the time slot offset indicated by the SOI domain across the indicator unit.
