[0030] The following description, in conjunction with the accompanying drawings, details the method and device for determining transmission parameters provided in the embodiments of this application through some examples and application scenarios.

[0031] like Figure 2As shown in the figure, this application embodiment provides a method 200 for determining transmission parameters. This method can be executed by a terminal. In other words, this method can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0032] S202: The terminal obtains configuration information, which includes at least one first SRS resource set configured for a first DCI format and at least one second SRS resource set configured for a second DCI format, wherein the second SRS resource set is configured based on the first SRS resource set.

[0033] In this embodiment, the first SRS resource set and the second SRS resource set can be used for PUSCH transmission. For example, the first SRS resource set is used for codebook-based PUSCH transmission, and the second SRS resource set is used for codebook-based PUSCH transmission; or, for another example, the first SRS resource set is used for non-codebook-based PUSCH transmission, and the second SRS resource set is used for non-codebook-based PUSCH transmission.

[0034] This configuration information can be configured by the network-side device. In this way, the terminal in S202 can receive configuration information from the network-side device, which can be carried by Radio Resource Control (RRC) signaling.

[0035] In this embodiment, the first DCI format can be DCI format 0_1, and the configuration information can be one or more of the first SRS resource sets configured for the first DCI format, such as two.

[0036] In this embodiment, the second DCI format can be DCI format 0_2, and the number of second SRS resource sets configured for the second DCI format can be one or more, for example, one or two.

[0037] In this embodiment, the first DCI format can be DCI format 0_2, and the configuration information can be one or more of the first SRS resource sets configured for the first DCI format, such as two.

[0038] In this embodiment, the second DCI format can be DCI format 0_1, and the number of second SRS resource sets configured for the second DCI format can be one or more, for example, one or two.

[0039] In this embodiment, the second SRS resource set is configured based on the first SRS resource set. For example, the first SRS resource set includes SRS resource set 1 and SRS resource set 2, and the second SRS resource set includes SRS resource set 3 and SRS resource set 4. SRS resource set 3 is associated with SRS resource set 1 and is configured based on SRS resource set 1; SRS resource set 4 is associated with SRS resource set 2 and is configured based on SRS resource set 2. Alternatively, the first SRS resource set includes SRS resource set 1 and SRS resource set 2, and the second SRS resource set includes SRS resource set 3. SRS resource set 3 is associated with SRS resource set 1 and is configured based on SRS resource set 1. Yet another example: the first SRS resource set includes SRS resource set 1, and the second SRS resource set includes SRS resource set 3 and SRS resource set 4. SRS resource set 3 is associated with SRS resource set 1 and is configured based on SRS resource set 1; SRS resource set 4 is not limited.

[0040] In this embodiment, the second SRS resource set is configured based on the first SRS resource set, which can be reflected in at least one of the following aspects:

[0041] 1) The second SRS resource set may include some or all of the same SRS resources based on the first SRS resource set. For example, the SRS resources included in the second SRS resource set are a subset of the SRS resources included in the first SRS resource set. Another example is that the second SRS resource set includes the first few SRS resources of the first SRS resource set. Specifically, for example, the first SRS resource set includes SRS resource 1, SRS resource 2, SRS resource 3, and SRS resource 4, and the second SRS resource set includes SRS resource 1 and SRS resource 2.

[0042] In this example, although the number of SRS resource sets has increased, the number of SRS resources has not increased. This is equivalent to not increasing the number of SRS resources that the terminal needs to detect, and not increasing the capability requirements of the terminal, which helps to reduce terminal costs.

[0043] 2) The second SRS resource set can use some or all of the same transmission parameters based on the first SRS resource set. These transmission parameters include, for example, transmission period, power control parameter set, etc.

[0044] This example can reduce the transmission parameters configured for the terminal, which helps to reduce the capability requirements of the terminal and reduce the terminal cost.

[0045] 3) Since the second SRS resource set includes some or all of the same SRS resources based on the first SRS resource set, the path loss reference signals associated with the second SRS resource set and the first SRS resource set can be updated simultaneously.

[0046] S204: The terminal determines the transmission parameters of the SRS resource according to the configuration information, wherein the SRS resource belongs to the first SRS resource set and / or the second SRS resource set.

[0047] The method for determining transmission parameters provided in this application embodiment can configure a first SRS resource set for a first DCI format and a second SRS resource set for a second DCI format. The second SRS resource set is configured based on the first SRS resource set. In this way, the first SRS resource set and the second SRS resource set can use some of the same configurations, which helps to reduce the capability requirements of the terminal and reduce the terminal cost.

[0048] Meanwhile, the first SRS resource set configured for the first DCI format can be one or more, and the second SRS resource set configured for the second DCI format can be one or more, which is beneficial for realizing PUSCH transmission of multiple TRPs.

[0049] Based on Embodiment 200, the second target SRS resource set in the at least one second SRS resource set is configured based on the first target SRS resource set in the at least one first SRS resource set. In this embodiment, the first target SRS resource set is one of the first SRS resource sets, and the second target SRS resource set is one of the second SRS resource sets.

[0050] In this embodiment, when the number X of the first SRS resource sets is less than the number Y of the second SRS resource sets, the X second target SRS resource sets in the Y second SRS resource sets are configured based on the X first SRS resource sets (since all SRS resource sets in the X first SRS resource sets are first target SRS resource sets, the X first SRS resource sets can also be called X first target SRS resource sets); or, when the number X of the first SRS resource sets is greater than or equal to the number Y of the second SRS resource sets, the Y second SRS resource sets (since all SRS resource sets in the Y second SRS resource sets are second target SRS resource sets, the Y second SRS resource sets can also be called Y second target SRS resource sets) are configured based on the Y first target SRS resource sets in the X first SRS resource sets. That is,

[0051] When the number X of the first SRS resource sets is less than the number Y of the second SRS resource sets, the X second target SRS resource sets in the Y second SRS resource sets are configured based on the X first target SRS resource sets.

[0052] When X is greater than Y, the Y second target SRS resource sets are configured based on the Y first target SRS resource sets in the X first SRS resource sets.

[0053] When X equals Y, the Y second target SRS resource sets are configured based on the X first target SRS resource sets respectively.

[0054] Optionally, in this embodiment, when the number X of the first SRS resource sets is less than the number Y of the second SRS resource sets, the X second target SRS resource sets in the Y second SRS resource sets are configured based on the X first target SRS resource sets respectively. The X second target SRS resource sets may be the first X or the last X second SRS resource sets in the Y second SRS resource sets.

[0055] When X is greater than Y, the Y second target SRS resource sets are respectively allocated based on the Y first target SRS resource sets in the X first SRS resource sets, wherein the Y first target resource sets are the first Y or the last Y first SRS resource sets in the X first SRS resource sets.

[0056] When X equals Y, the Y second target SRS resource sets are configured based on the X first target SRS resource sets respectively.

[0057] Optionally, in this embodiment, when the number X of the first SRS resource sets is less than the number Y of the second SRS resource sets, the X second target SRS resource sets in the Y second SRS resource sets are configured based on the X first target SRS resource sets. The X second target SRS resource sets can be the first X or the last X second SRS resource sets after the Y second SRS resource sets are sorted by index from smallest to largest.

[0058] When X is greater than Y, the Y second target SRS resource sets are respectively allocated based on the Y first target SRS resource sets in the X first SRS resource sets. The Y first target resource sets are the first Y or the last Y first SRS resource sets after the X first SRS resource sets are sorted by index from smallest to largest.

[0059] When X equals Y, the Y second target SRS resource sets are configured based on the X first target SRS resource sets respectively.

[0060] Optionally, in this embodiment, the first target SRS resource set and the second target SRS resource set are respectively sorted by index from smallest to largest and then correspond to each other, and the second target SRS resource set is configured based on the corresponding first target SRS resource set.

[0061] In this embodiment, for example, if the number of first SRS resource sets is 1 and the number of second SRS resource sets is 2, then one of the second target SRS resource sets in the two second SRS resource sets needs to be configured based on the first target SRS resource set. The second target SRS resource set can be either of the two second SRS resource sets, or the first one, or the one with the smaller SRS resource set index.

[0062] For example, in this embodiment, if the number of first SRS resource sets is 2 and the number of second SRS resource sets is 1, then a second target SRS resource set needs to be configured based on one of the two first SRS resource sets. The first target SRS resource set can be either of the two first SRS resource sets, or the first one, or the one with the smaller SRS resource set index.

[0063] In this embodiment, the configuration of the second target SRS resource set may include: N SRS resources within the first target SRS resource set and a first configuration parameter for the first target SRS resource set; wherein, the first target SRS resource set includes M SRS resources, M≥N, and M and N are positive integers. The N SRS resources within the first target SRS resource set mentioned here may be the first N SRS resources within the first target SRS resource set, which may be determined according to the SRS resource numbers in ascending order, or according to the position of the SRS resources within the first target SRS resource set.

[0064] In this embodiment, for example, the second target SRS resource set consists of the first N SRS resources of the first target SRS resource set and a first configuration parameter of the first target SRS resource set. The first configuration parameter includes, for example, transmission period, power control parameter set, etc.

[0065] This embodiment not only helps to reduce the overhead of configuration information, but also reduces the overhead of the second DCI format because the number of SRS resources in the second target SRS resource set is less than the number of SRS resources in the first target SRS resource set. For example, it reduces the overhead of the SRS Resource Indicator (SRI) field in the second DCI format.

[0066] In this embodiment, the terminal can first determine the first target SRS resource set associated with the second target SRS resource set based on configuration information, and then determine the configuration of the second target SRS resource set based on the configuration of the first target SRS resource set. The following three examples illustrate how the terminal determines the first target SRS resource set associated with the second target SRS resource set, or in other words, how the terminal determines the association between the first target SRS resource set and the second target SRS resource set.

[0067] Example 1: Implicitly determine association relationships based on the size of the SRS resource set identifier or the relative position of the SRS resource sets.

[0068] Optionally, the method further includes: the terminal determining the association between the first target SRS resource set and the second target SRS resource set based on at least one of the following:

[0069] 1) The sorting results of multiple first SRS resource sets according to the identifier size and the sorting results of multiple second SRS resource sets according to the identifier size.

[0070] This example can sort the identifiers of multiple first SRS resource sets in the first SRS resource set sequence in ascending order, sort the identifiers of multiple second SRS resource sets in the second SRS resource set sequence in ascending order, and associate the second SRS resource sets with the first SRS resource sets according to the identifier size.

[0071] For example, if the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, and the second SRS resource set sequence includes SRS resource set 3 and SRS resource set 4, then SRS resource set 3 is associated with SRS resource set 1, and SRS resource set 4 is associated with SRS resource set 2.

[0072] It is understandable that the above is an example of sorting the identifiers from smallest to largest. In fact, sorting the identifiers from largest to smallest can also determine the association between the first target SRS resource set and the second target SRS resource set.

[0073] 2) The relative positions of the multiple first SRS resource sets in the first SRS resource set sequence and the relative positions of the multiple second SRS resource sets in the second SRS resource set sequence.

[0074] This example demonstrates how associations can be determined based on the relative position of an SRS resource set within its corresponding SRS resource set sequence.

[0075] For example, the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, with SRS resource set 1 appearing first and SRS resource set 2 appearing last. The second SRS resource set sequence includes SRS resource set 3 and SRS resource set 4, with SRS resource set 3 appearing first and SRS resource set 4 appearing last. In this case, SRS resource set 3 is associated with SRS resource set 1, and SRS resource set 4 is associated with SRS resource set 2.

[0076] Example 2: Predefined associations.

[0077] 1) The second target SRS resource set is associated with the first target SRS resource set with the smallest identifier in the sequence of first SRS resource sets.

[0078] For example, the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, the second SRS resource set sequence includes SRS resource set 3 (i.e. the second target SRS resource set), and SRS resource set 3 is associated with the first SRS resource set identifier 1 (i.e. the first target SRS resource set) with the smallest identifier in the first SRS resource set sequence.

[0079] 2) The second target SRS resource set is associated with the first first target SRS resource set in the first SRS resource set sequence.

[0080] For example, the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, with SRS resource set 1 preceding SRS resource set 2. The second SRS resource set sequence includes SRS resource set 3 (i.e., the second target SRS resource set), which is associated with the first SRS resource set identifier 1 (i.e., the first target SRS resource set) in the first SRS resource set sequence.

[0081] This embodiment can realize multi-TRP scheduling of TRP1 in the second DCI format. For example, the first SRS resource set sequence includes SRS resource set 1 (corresponding to TRP1) and SRS resource set 2 (corresponding to TRP2). When the second target SRS resource set is associated with the first first SRS resource set (i.e. SRS resource set 1) in the first SRS resource set sequence, if the second DCI format indicates the second target SRS resource set, the PUSCH scheduled in the second DCI format can be sent to TRP1.

[0082] Example 3: Explicitly indicated relationships.

[0083] Optionally, the method further includes: the terminal determining the association between the first target SRS resource set and the second target SRS resource set based on at least one of the following:

[0084] 1) Identify the same SRS resource set association.

[0085] For example, if the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, and the second SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, then SRS resource set 1 of the second SRS resource set sequence (i.e., the second target SRS resource set) is associated with SRS resource set 1 of the first SRS resource set sequence (i.e., the first target SRS resource set), and SRS resource set 2 of the second SRS resource set sequence (i.e., the second target SRS resource set) is associated with SRS resource set 2 of the first SRS resource set sequence (i.e., the first target SRS resource set).

[0086] 2) A first parameter carried within the SRS resource set, the first parameter being used to indicate the SRS resource set associated with the SRS resource set.

[0087] The SRS resource set mentioned here may include a first target SRS resource set and a second target SRS resource set.

[0088] Optionally, the first parameter satisfies at least one of the following:

[0089] 1) The first parameter is the SRS resource set identifier.

[0090] 2) The first parameter is used to indicate which SRS resource in the corresponding SRS resource set is associated with.

[0091] Optionally, based on any of the previously described embodiments, the method further includes: the terminal receiving a Media Access Control Control Element (MAC CE); the terminal updating the path loss reference signal associated with the first target SRS resource set and the path loss reference signal associated with the second target SRS resource set according to the MAC CE. Alternatively,

[0092] The terminal updates the path loss reference signal of all SRS resources in the first target SRS resource set according to the MAC CE.

[0093] In this embodiment, since the first target SRS resource set is associated with the second target SRS resource set, and the first target SRS resource set and the second target SRS resource set may include some or all of the same SRS resources, when the MAC CE updates the path loss reference signal corresponding to all SRS resources in the first target resource set, the path loss reference signal associated with the SRS resources in the second target SRS resource set is updated simultaneously.

[0094] In one example, the MAC CE includes a path loss reference signal identifier used to update the path loss reference signal associated with the identifier of the first target SRS resource set and the path loss reference signal associated with the identifier of the second target SRS resource set associated with the first target SRS resource set; or, the MAC CE includes a path loss reference signal identifier used to update the path loss reference signal associated with the identifier of the second target SRS resource set and the path loss reference signal associated with the identifier of the first target SRS resource set associated with the second target SRS resource set.

[0095] For example, a first SRS resource set is configured with two SRS resource sets, SRS resource set 1 and SRS resource set 2, and a second SRS resource set is configured with two SRS resource sets, SRS resource set 3 and SRS resource set 4. SRS resource set 3 is configured based on SRS resource set 1, and SRS resource set 4 is configured based on SRS resource set 2. When the MAC CE carries the index of SRS resource set 1, the path loss reference signal of the corresponding SRS resource set 3 is simultaneously updated to the path loss reference signal indicated by the path loss reference signal index in the MAC CE. Similarly, when the MAC CE carries the index of SRS resource set 4, the path loss reference signal of the corresponding SRS resource set 2 is simultaneously updated to the path loss reference signal indicated by the path loss reference signal index in the MAC CE.

[0096] In this embodiment, the MAC CE may contain the identifier of any target SRS resource set in the interrelated target SRS resource sets. Then, the path loss reference signal identifier contained in the MAC CE is used to update the path loss reference signals associated with all interrelated target SRS resource sets.

[0097] In this embodiment, the MAC CE may simultaneously include the identifiers of multiple target SRS resource sets and the identifier of at least one path loss reference signal. The path loss reference signal identifier is used to update the path loss reference signal associated with the SRS resource set corresponding to the multiple target SRS resource set identifiers.

[0098] In another example, the MAC CE includes a first MAC CE and a second MAC CE; wherein the first MAC CE includes a path loss reference signal identifier for updating the path loss reference signal associated with the first target SRS resource set; and the second MAC CE includes a path loss reference signal identifier for updating the path loss reference signal associated with the second target SRS resource set.

[0099] In this embodiment, for mutually related target SRS resource sets, the terminal receives multiple MAC CEs that simultaneously update the path loss reference signals associated with the multiple target SRS resource sets.

[0100] In the above embodiments, the terminal determining the transmission parameters of the SRS resource based on the configuration information includes: the terminal determining the transmission parameters of the SRS resource based on the configuration information and the path loss reference signal indicated by the MAC CE.

[0101] Optionally, based on any of the previously described embodiments, the method further includes: the terminal receiving a third DCI in a third DCI format, wherein the third DCI format is either the first DCI format or the second DCI format; and the terminal determining the transmission parameters of the PUSCH based on the configuration information, the third DCI format, and the information carried by the third DCI. In this embodiment, the first SRS resource set and the second SRS resource set are used for Physical Uplink Shared Channel (PUSCH) transmission.

[0102] In one example, the transmission parameters of the PUSCH include a set of power control parameters. The terminal determines the transmission parameters of the PUSCH based on the configuration information, the third DCI format, and the information carried by the third DCI, including: the terminal determines the third SRS resource set corresponding to the PUSCH based on the configuration information, the third DCI format, and the information carried by the third DCI, wherein the third SRS resource set is the second target SRS resource set or the first target SRS resource set; the terminal determines the power control parameter set sequence of the PUSCH based on the third SRS resource set; and the terminal determines the power control parameter set of the PUSCH from the power control parameter set sequence based on the value of the SRS Resource Indicator (SRI) field in the third DCI.

[0103] Optionally, the terminal determines the power control parameter set sequence of the PUSCH based on the third SRS resource set, including:

[0104] 1) The terminal uses the power control parameter set sequence corresponding to the third SRS resource set as the power control parameter set sequence of the PUSCH; or

[0105] 2) The terminal uses the power control parameter set sequence corresponding to the SRS resource set associated with the third SRS resource set as the power control parameter set of the PUSCH; wherein the third SRS resource set and the SRS resource set associated with the third SRS resource set correspond to the same power control parameter set sequence.
