[0009] Detailed Description The present application will be described in conjunction with the following drawings and embodiments. The specific embodiments described in this specification are used solely to describe the present application. For ease of description, only parts relevant to the present application are shown in the drawings.

[0010] In an embodiment of the present application, an indication method is provided, in which a bit in an SOI field corresponding to one indication unit can be used to indicate another indication unit by setting the bit width of the SOI field of each indication unit uniformly, so that indication across indication units of an SRS transmission slot is achieved, and the reliability and flexibility of indication of a reference signal transmitting a slot is improved.

[0011] 1 is a flowchart of an indication method provided in an embodiment. The method can be applied to a first communication node, for example, a network side device such as a base station. As shown in FIG. 1, the method provided in this embodiment includes steps 110 and 120.

[0012] In step 110, the bit width of a slot offset indication (SOI) field is determined according to the number of slot indication parameters configured in the reference signal resource set of the indication unit.

[0013] In step 120, downlink control information (DCI) is transmitted, the DCI including an SOI field.

[0014] In this embodiment, the indication unit is a unit for indicating an SRS transmission slot, which may be a CC or a BWP. The reference signal mainly refers to aperiodic SRS. The SOI field of the DCI is used to indicate that the second communication node (e.g., a terminal) transmits a reference signal in the (t+1)th available slot, where t is a slot indication parameter and is a key parameter for determining the transmission of the reference signal. In the case of the (t+1)th available slot, whose counted reference point may be slot n or slot n+k, 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 in the upper layer radio resource control (RRC) parameter (slotOffset).

[0015] In this embodiment, multiple slot indication parameters t for each indication unit may be configured in the reference signal resource set, for example, three CCs are configured, denoted as CC0, CC1, and CC2, and the number of t values ​​configured in the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC2 is 2. The bit width of the SOI field may be determined according to the number of slot indication parameters configured in the reference signal resource set of each indication unit. For example, for CC0, the number of t values ​​is configured to be 2, and the bit width of the SOI field may be log22, i.e., one bit may be used to indicate which t value is adopted. As another example, in order to make sufficient bits available in the SOI field corresponding to CC0 to indicate the t value of CC1, the SOI field of CC0 may be extended to 2 bits to indicate which t value is adopted among the number of 4 t values ​​configured by CC1.

[0016] Based on the above, the first communication node may uniformly configure the bit width of the SOI field of each indication unit, so that indication over the indication unit of the SRS transmission slot is achieved, and the reliability and flexibility of indication of the reference signal transmitting slot is improved.

[0017] In an embodiment, determining the bit width of the SOI field according to 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 according to the maximum value of the number of slot indication parameters configured in the reference signal resource set of all indication units, and the bit width of the SOI field corresponding to each indication unit is the same.

[0018] In this embodiment, the bit width of the SOI field corresponding to each indication unit is the same, and depends on the maximum value of the number of slot indication parameters configured in the reference signal resource set of each indication unit. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC1 is 4, the number of t values ​​configured in the aperiodic SRS resource set on CC2 is 2, the maximum number of t values ​​configured in the aperiodic SRS resource set is 4, and the bit width of the SOI field corresponding to each CC is log24, that is, 2.

[0019] Similarly, in one CC, if the number of t values ​​configured for the aperiodic SRS resource set on BWP0 is 2, the number of t values ​​configured for the aperiodic SRS resource set on BWP1 is 4, the number of t values ​​configured for the aperiodic SRS resource set on BWP2 is 2, and the maximum number of t values ​​configured for the aperiodic SRS resource sets is 4, then the bit width of the SOI field corresponding to each BWP is log24=2.

[0020] In an embodiment, the plurality of indication units includes a first indication unit and a second indication unit, the first indication unit includes an indication unit in which the number of slot indication parameters configured in the reference signal resource set is less than a maximum value, and the second indication unit includes an indication unit in which the number of slot indication parameters configured in the reference signal resource set is equal to a maximum value. All or a part of the bits in the SOI field corresponding to the first indication unit are used to indicate the value of the slot indication parameter in the reference signal resource set of the second indication unit or to select the slot indication parameter in the reference signal resource set of the second indication unit.

[0021] In this embodiment, the bit width of the SOI field corresponding to each indication unit is the same and depends on the maximum value of the number of slot indication parameters configured in the reference signal resource set of each indication unit. The indication units are divided into two categories, one category is the first indication unit, the number of slot indication parameters configured in the reference signal resource set of the first indication unit is not the maximum value of the number of slot indication parameters corresponding to each indication unit, i.e., the bit width of the SOI field corresponding to the first indication unit is determined by the number of slot indication parameters configured in the reference signal resource set of the other indication unit. Another category is the second indication unit, the number of slot indication parameters configured in the reference signal resource set of the second indication unit is the maximum value of the number of slot indication parameters corresponding to each indication unit, i.e., the bit width of the SOI field corresponding to the second indication unit is determined by the number of slot indication parameters configured in its own reference signal resource set. For example, the number of t values ​​configured for the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured for the aperiodic SRS resource set on CC1 is 4, and the number of t values ​​configured for the aperiodic SRS resource set on CC2 is 2, in which case both CC0 and CC2 are first units of indication, and CC1 is the second unit of indication.

[0022] In this embodiment, for the indication of the slot indication parameter t in the first indication unit, the value of the slot indication parameter in the reference signal resource set of the SOI field corresponding to the first indication unit may be indicated, or the slot indication parameter in the reference signal resource set of the SOI field corresponding to the first indication unit may be selected, by using a part of the bits in the SOI field corresponding to the first indication unit. For example, in the case of an SOI field on CC0 (having a bit width of 2 bits), the t value on CC0 may be indicated or selected using a bit of the most significant bit or a bit of the least significant bit. For an SOI field on CC2 (having a bit width of 2 bits), the t value on CC2 may be indicated or selected using an SOI having a bit of the most significant bit or a bit of the least significant bit.

[0023] In this embodiment, for the indication of the slot indication parameter t across indication units, all or part of the bits in the SOI field corresponding to the first indication unit may be used to indicate the value of the slot indication parameter in the reference signal resource set of the second indication unit or to select the slot indication parameter in the reference signal resource set of the second indication unit. For example, the t value on CC1 may be indicated or selected by using the SOI field on CC0, and then all bits (2 bits) of the SOI field of CC0 may be used to indicate or select the t value on CC1, for a total of four. The value of t on CC1 may also be indicated or selected by using some bits (1 bit, which may be the upper bit or lower bit) of the SOI field of CC0, for a total of two. The above example is equally applicable to multiple BWPs in a CC.

[0024] In an embodiment, the plurality of indication units includes a first indication unit and a second indication unit, the first indication unit includes an indication unit in which the number of slot indication parameters configured in the reference signal resource set is less than a maximum value, and the second indication unit includes an indication unit in which the number of slot indication parameters configured in the reference signal resource set is equal to a maximum value. A part of the bits in the SOI field corresponding to the second indication unit is used to indicate a value of the slot indication parameter in the reference signal resource set of the first indication unit or to select the slot indication parameter in the reference signal resource set of the first indication unit.

[0025] In this embodiment, the bit width of the SOI field corresponding to each indication unit is the same, and depends on the maximum value of the number of slot indication parameters configured in the reference signal resource set of each indication unit. The multiple indication units are divided into two categories. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC2 is 2, in this case, both CC0 and CC2 are the first indication unit, and CC1 is the second indication unit.

[0026] In this embodiment, for the indication of the slot indication parameter t over the indication unit, some of the bits in the SOI field corresponding to the second indication unit may be used to indicate the value of the slot indication parameter in the reference signal resource set of the first indication unit or to select the slot indication parameter in the reference signal resource set of the first indication unit. For example, t values ​​on CC0 or CC2 are indicated or selected by using the SOI field on CC1, and t values ​​on CC0 or CC2 are indicated or selected by using the SOI of the upper 1 bit or the lower 1 bit of the SOI field on CC1, thereby achieving indication over the time field unit. The above example is equally applicable to multiple BWPs in a CC.

[0027] In an embodiment, determining the bit width of the SOI field according to the number of slot indication parameters configured in the reference signal resource set of the instruction unit includes determining the bit width of the SOI field corresponding to each instruction unit according to the number of slot indication parameters configured in the reference signal resource set of each instruction unit.

[0028] In this embodiment, the bit width of the SOI field corresponding to multiple indication units may be different, and the bit width of the SOI field corresponding to each indication unit depends on the number of slot indication parameters configured in the reference signal resource set of each indication unit. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC1 is 4, the number of t values ​​configured in the aperiodic SRS resource set on CC2 is 2, the SOI bit width on CC0 is log22=1, the SOI bit width on CC1 is log24=2, and the SOI bit width on CC2 is log22=1. The above example is equally applicable to multiple BWPs in a CC.

[0029] In an embodiment, the plurality of indication units includes a third indication unit and a fourth indication unit, and the number of slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of slot indication parameters configured in the reference signal resource set of the fourth indication unit. A part of the bits in the SOI field corresponding to the fourth indication unit is used to indicate the value of the slot indication parameter in the reference signal resource set of the third indication unit or to select the slot indication parameter in the reference signal resource set of the third indication unit.

[0030] In this embodiment, the bit width of the SOI field corresponding to each indication unit depends on the number of slot indication parameters configured in the reference signal resource set of the indication unit. The multiple indication units are divided into two categories, one category is the third indication unit, and another category is the fourth indication unit, and the number of slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of slot indication parameters configured in the reference signal resource set of the fourth indication unit, that is, the bit width of the SOI field corresponding to the third indication unit is less than the bit width of the SOI field corresponding to the fourth indication unit. For example, the number of t values ​​configured in the aperiodic SRS resource set on CC0 is 2, the number of t values ​​configured in the aperiodic SRS resource set on CC1 is 4, and the number of t values ​​configured in the aperiodic SRS resource set on CC2 is 2, in which case CC0 and CC2 are the third indication unit, and CC1 is the fourth indication unit, respectively.

[0031] In this embodiment, for the indication of the slot indication parameter t across indication units, some of the bits in the SOI field corresponding to the fourth indication unit may be used to indicate or select the value of the slot indication parameter in the reference signal resource set of the third indication unit. For example, the t values ​​on CC0 or CC2 are indicated or selected using the most significant bit or the least significant bit in the 2-bit SOI field on CC1. The above example is equally applicable to multiple BWPs in a CC.

[0032] In an embodiment, the plurality of indication units includes a third indication unit and a fourth indication unit, and the number of slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of slot indication parameters configured in the reference signal resource set of the fourth indication unit. After the upper or lower bits in the SOI field corresponding to the third indication unit are filled with 0 or 1, the bits in the SOI field corresponding to the third indication unit are used to indicate the value of the slot indication parameter in the reference signal resource set of the fourth indication unit or to select the slot indication parameter in the reference signal resource set of the fourth indication unit. After the upper or lower bits in the SOI field corresponding to the third indication unit are filled with 0 or 1, the size of the SOI field corresponding to the third indication unit is equal to the size of the SOI field corresponding to the fourth indication unit.

[0033] In this embodiment, the bit width of the SOI field corresponding to each indication unit depends on the number of slot indication parameters configured in the reference signal resource set of the indication unit.The indication units are divided into two categories, one category is the third indication unit, and another category is the fourth indication unit, and the number of slot indication parameters configured in the reference signal resource set of the third indication unit is less than the number of slot indication parameters configured in the reference signal resource set of the fourth indication unit.

[0034] In the case of indication of the slot indication parameter t across indication units, the upper or lower bits in the SOI field corresponding to the third indication unit may be filled with 0 or 1, so that the bit width of the SOI field corresponding to the third indication unit is equal to the bit width of the SOI field corresponding to the fourth indication unit, and then the bit in the SOI field corresponding to the third indication unit is used to indicate or select the value of the slot indication parameter in the reference signal resource set of the fourth indication unit. For example, a SOI field with 1 bit on CC0 or CC2 is used to indicate a t value on CC1 across CCs, and then the upper or lower bits of the SOI field on CC0 or CC2 are filled with 0 or 1, so that the bit width of the SOI field on CC0 or CC2 is the same as the bit width of the SOI field on CC1, and then the t value on CC1 is indicated via the SOI field on CC0 or CC2 after being filled with the value. The filled bits are combined with the original bits (total of 2 bits) to select the number of t values ​​up to 2. 2 =4 is indicated. The above example is equally applicable to multiple BWPs within a CC.

[0035] In an embodiment, the format of the DCI corresponding to the reference signal resource set is non-DCI2-3.

[0036] In this embodiment, the format of the DCI may be a format other than DCI2-3. If the format of the DCI is DCI2-3, that is, if the reference signal resource set is a resource set used by or associated with DCI2-3, the configuration of t is ignored.

[0037] In an embodiment, the unit of reference includes a component carrier (CC) and / or a bandwidth portion (BWP).

[0038] In an embodiment, the SOI field is used to indicate a value of a slot indication parameter in a reference signal resource set of the terminal or to select a slot indication parameter in a reference signal resource set of the terminal, the reference signal including an SRS; When the terminal is configured with a carrier aggregation-slot offset parameter (ca-SlotOffset), the terminal transmits a reference signal in each of the triggered reference signal resource sets of the indication unit in the (t+1)th available slot according to a t value indicated by the SOI field in the received DCI, the reference signal mainly refers to the SRS, and the available slots are the following slots: [ka] or [ka] It is counted from If the terminal is not configured with a carrier aggregation-slot offset parameter, the terminal transmits a reference slot in each of the triggered reference signal resource sets of the indication unit in the (t+1)th available slot according to a t value indicated by the SOI field in the received DCI, the available slots being the following slots: [ka] or [ka] It is counted from where t is a slot indication parameter, n is a slot index for receiving DCI, k is a slot offset parameter configured for each of the triggered SRS resource sets of the indication unit in the higher layer parameters, k is associated with the subcarrier spacing of the triggered SRS transmission, and μSRS is the subcarrier spacing of the triggered SRS transmission, and μ PDCCH is the subcarrier spacing of the physical downlink control channel (PDCCH) carrying the trigger command, [ka] is a carrier aggregation-slot offset parameter configured for a cell receiving a PDCCH, representing a slot offset between a primary cell and a secondary cell or between a primary secondary cell and a secondary cell; [ka] is the maximum of the lowest subcarrier spacing configurations (i.e., the maximum value of the lowest subcarrier spacing configurations) among the subcarrier spacings configured in the higher layer parameters for the cell receiving the PDCCH; [ka] is a carrier aggregation-slot offset parameter configured for the cell transmitting the SRS, representing a slot offset between the primary cell and the secondary cell or between the primary secondary cell and the secondary cell; [ka] is the maximum of the lowest subcarrier spacing configurations among the subcarrier spacings configured in the higher layer parameters of the cell transmitting the SRS (i.e., the maximum value of the lowest subcarrier spacing configuration).

[0039] Based on this, regardless of whether the terminal is configured by the carrier aggregation-slot offset parameter, the reference signal can be transmitted accurately according to the indication of the SOI field, thereby improving the flexibility and reliability of the transmission of the reference signal. In this embodiment, the terminal (user equipment, UE) receives a DCI triggering an aperiodic SRS in slot n, excluding the case where the SRS is configured by the higher layer parameter SRS-PosResource-r16. In the embodiment, the SOI field is used to indicate a value of a slot indication parameter in a reference signal resource set of the terminal or to select a slot indication parameter in a reference signal resource set of the terminal, the reference signal includes an SRS, When configured by the carrier aggregation-slot offset parameter, the terminal transmits a reference signal in each of the triggered reference signal resource sets of the indicated unit in the following slots according to a t value indicated by the SOI field in the received DCI; [ka] or [ka] The terminal transmits a reference signal in each of the triggered reference signal resource sets of the indication unit in the following slots if not configured with a carrier aggregation-slot offset parameter; [ka] or [ka] where t is a slot indication parameter, n is a slot index for receiving DCI, k is a slot offset parameter configured for each of the triggered SRS resource sets in the higher layer parameters, k is associated with the subcarrier spacing of the triggered SRS transmission, and μ SRS is the subcarrier spacing of the triggered SRS transmission, and μ PDCCH is the subcarrier spacing of the physical downlink control channel (PDCCH) carrying the trigger command, [ka] is a carrier aggregation-slot offset parameter configured for a cell receiving a PDCCH, representing a slot offset between the primary cell and the secondary cell or between the configured primary secondary cell and the secondary cell; [ka] is the maximum of the lowest subcarrier spacing configurations (i.e., the maximum value of the lowest subcarrier spacing configurations) among the subcarrier spacings configured in the higher layer parameters for the cell receiving the PDCCH; [ka] is a carrier aggregation-slot offset parameter configured for the cell transmitting the SRS, representing a slot offset between the primary cell and the secondary cell or between the primary secondary cell and the secondary cell; [ka] is the maximum of the lowest subcarrier spacing configurations among the subcarrier spacings configured in the higher layer parameters of the cell transmitting the SRS (i.e., the maximum value of the lowest subcarrier spacing configuration).

[0040] In an embodiment of the present application, a reference signal transmission method is further provided, in which an SRS can be accurately transmitted per indication unit according to a slot offset indicated over the SOI field of the indication unit.
