The following describes in detail a method and an apparatus for determining transmission parameters according to embodiments of the present application with reference to the accompanying drawings.

As shown in fig. 2, the present embodiment provides a method 200 for determining transmission parameters, which may be performed by a terminal, in other words, by software or hardware installed in the terminal, and the method includes the following steps.

S202: the terminal acquires configuration information, wherein the configuration information comprises 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, and the second SRS resource set is configured based on the first SRS resource set.

In this embodiment, the first set of SRS resources and the second set of SRS resources may be used for PUSCH transmission. For example, the first set of SRS resources is for codebook-based PUSCH transmission and the second set of SRS resources is for codebook-based PUSCH transmission; for another example, the first set of SRS resources is used for non-codebook based PUSCH transmission and the second set of SRS resources is used for non-codebook based PUSCH transmission.

The configuration information may be configured by the network side device, so that the terminal in S202 may receive the configuration information from the network side device, and the configuration information may be carried by Radio Resource Control (RRC) signaling.

In this embodiment, the first DCI format may be DCI format 0_1 (DCI format 0_1), and the number of the first SRS resource sets configured for the first DCI format by the configuration information may be one or more, for example, 2.

In this embodiment, the second DCI format may be DCI format 0_2 (DCI format 0_2), and the number of the second SRS resource sets configured by the configuration information for the second DCI format may be one or more, for example, 1 or 2.

In this embodiment, the first DCI format may be DCI format 0_2 (DCI format 0_2), and the number of the first SRS resource sets configured for the first DCI format by the configuration information may be one or more, for example, 2.

In this embodiment, the second DCI format may be DCI format 0_1 (DCI format 0_1), and the number of the second SRS resource sets configured by the configuration information for the second DCI format may be one or more, for example, 1 or 2.

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, 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, SRS resource set 3 is configured based on SRS resource set 1; SRS resource set 4 is associated with SRS resource set 2, SRS resource set 4 being configured based on SRS resource set 2. For another example, the first set of SRS resources includes SRS resource set 1 and SRS resource set 2, the second set of SRS resources includes SRS resource set 3, SRS resource set 3 is associated with SRS resource set 1, and SRS resource set 3 is configured based on SRS resource set 1. For another example, the first set of SRS resources includes set 1 of SRS resources, the second set of SRS resources includes set 3 of SRS resources and set 4 of SRS resources, set 3 of SRS resources is associated with set 1 of SRS resources, set 3 of SRS resources is configured based on set 1 of SRS resources, and set 4 of SRS resources is not limited.

In this embodiment, the second SRS resource set may be configured based on the first SRS resource set, and may be embodied in at least one of the following aspects:

1) The second set of SRS resources may include partially or completely identical SRS resources based on the first set of SRS resources, e.g., the SRS resources included in the second set of SRS resources are a subset of the SRS resources included in the first set of SRS resources. For another example, the second set of SRS resources includes the first few SRS resources of the first set of SRS resources. 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.

In this example, although the number of SRS resource sets is increased, the number of SRS resources is not increased, which is equivalent to not increasing the number of SRS resources that the terminal needs to detect, and not increasing the capability requirement for the terminal, which is beneficial to reducing the terminal cost.

2) The second set of SRS resources may use some or all of the same transmission parameters, including, for example, transmission periodicity, set of power control parameters, etc., based on the first set of SRS resources.

In this example, the transmission parameters configured for the terminal may be reduced, which is beneficial to reducing the capability requirement on the terminal and reducing the terminal cost.

3) Since the second set of SRS resources includes partially or completely identical SRS resources based on the first set of SRS resources, the path loss reference signals associated with the second set of SRS resources and the first set of SRS resources may be updated simultaneously.

S204: and the terminal determines the transmission parameters of SRS resources according to the configuration information, wherein the SRS resources belong to the first SRS resource set and/or the second SRS resource set.

The method for determining transmission parameters provided in the embodiment of the present application may configure a first SRS resource set for a first DCI format and configure a second SRS resource set for a second DCI format, where the second SRS resource set is configured based on the first SRS resource set, and thus, the first SRS resource set and the second SRS resource set may use some same configurations, which is beneficial to reducing capability requirements for a terminal and reducing terminal cost.

Meanwhile, the number of the first SRS resource sets configured for the first DCI format may be one or more, and the number of the second SRS resource sets configured for the second DCI format may be one or more, which is beneficial to implementing multi-TRP PUSCH transmission.

On the basis of embodiment 200, a second target SRS resource set of the at least one second SRS resource set is configured based on a first target SRS resource set of the at least one first SRS resource set. In this embodiment, the first set of target SRS resources is one of the first set of SRS resources and the second set of target SRS resources is one of the second set of SRS resources.

In this embodiment, when the number X of the first SRS resource sets is smaller than the number Y of the second SRS resource sets, X second target SRS resource sets in Y second SRS resource sets are configured based on X first SRS resource sets (since all SRS resource sets in the X first SRS resource sets are the first target SRS resource sets, the X first SRS resource sets may also be referred to as 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, Y of the 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 may also be referred to as Y second target SRS resource sets) are configured based on Y of the X first SRS resource sets respectively. That is to say that the position of the first electrode,

and when the number X of the first SRS resource sets is smaller than the number Y of the second SRS resource sets, 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.

When X is greater than Y, the Y second target SRS resource sets are configured based on Y first target SRS resource sets of the X first SRS resource sets, respectively.

When X is equal to Y, Y second target SRS resource sets are configured based on the X first target SRS resource sets, respectively.

Optionally, in this embodiment, when the number X of the first SRS resource sets is smaller than the number Y of the second SRS resource sets, 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, and 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.

When X is greater than Y, the Y second target SRS resource sets are respectively allocated based on Y first target SRS resource sets in the X first SRS resource sets, and the Y first target resource sets are the front Y or the back Y first SRS resource sets in the X first SRS resource sets.

Optionally, in this embodiment, when the number X of the first SRS resource sets is smaller than the number Y of the second SRS resource sets, X second target SRS resource sets in the Y second SRS resource sets are configured based on the X first target SRS resource sets, and the X second target SRS resource sets may be the first X or the last X second SRS resource sets after the Y second SRS resource sets are sorted from small to large according to the index.

When X is larger than Y, the Y second target SRS resource sets are respectively matched based on Y first target SRS resource sets in the X first SRS resource sets, and the Y first target resource sets are front Y or rear Y first SRS resource sets which are sequenced from small to large according to indexes of the X first SRS resource sets.

Optionally, in this embodiment, the first target SRS resource set and the second target SRS resource set are respectively ordered from small to large according to the index and then correspond to each other, and the second target SRS resource set is configured based on the corresponding first target SRS resource set.

For example, the number of the first SRS resource sets is 1, and the number of the second SRS resource sets is 2, then one second target SRS resource set of the 2 second SRS resource sets needs to be configured based on the first target SRS resource set, and the second target SRS resource set may be any one of the two second SRS resource sets, or the first one, or one with a smaller SRS resource set index.

For example, the number of the first SRS resource sets is 2, and the number of the second SRS resource sets is 1, then one second target SRS resource set needs to be configured based on one first target SRS resource set of the two first SRS resource sets, where the first target SRS resource set may be any one of the two first SRS resource sets, or the first one, or one with a smaller SRS resource set index.

In this embodiment, the configuring of the second target SRS resource set may include: n SRS resources within the first set of target SRS resources and a first configuration parameter of the first set of target SRS resources; the first target SRS resource set comprises M SRS resources, M is larger than or equal to N, and M and N are positive integers. The N SRS resources in the first target SRS resource set mentioned here may be the first N SRS resources in the first target SRS resource set, and the first N SRS resources may be determined according to the ascending order of the SRS resource numbers, or according to the positions of the SRS resources in the first target SRS resource set.

For example, the second target SRS resource set is composed of the first N SRS resources of the first target SRS resource set and the first configuration parameters of the first target SRS resource set, and the first configuration parameters include, for example, a transmission period, a power control parameter set, and the like.

The embodiment is not only beneficial to reducing the overhead of configuration information; meanwhile, since 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, the overhead of the second DCI format may also be reduced, for example, the overhead of an SRS Resource Indicator (SRI) field in the second DCI format is reduced.

In this embodiment, the terminal may first determine the first target SRS resource set associated with the second target SRS resource set according to the configuration information, and then determine the configuration of the second target SRS resource set according to the configuration of the first target SRS resource set. How a terminal determines the first target SRS resource set associated with the second target SRS resource set, or how the terminal determines the association relationship between the first target SRS resource set and the second target SRS resource set, will be described in three examples below.

Example one: and implicitly determining the association relation according to the identification size ordering of the SRS resource sets or the relative positions of the SRS resource sets.

Optionally, the method further comprises: the terminal determines the first target SRS resource set and the second target SRS resource set association according to at least one of:

1) And the sequencing result of the plurality of first SRS resource sets according to the identification size and the sequencing result of the plurality of second SRS resource sets according to the identification size.

In this example, the identifiers of the plurality of first SRS resource sets in the first SRS resource set sequence may be sorted from small to large, the identifiers of the plurality of second SRS resource sets in the second SRS resource set sequence may be sorted from small to large, and the second SRS resource sets may be associated with the first SRS resource sets in the order of the sizes of the identifiers.

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 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.

It can be understood that, the above description is given by taking the ordering of the identifiers from small to large as an example, and actually, the association between the first target SRS resource set and the second target SRS resource set can also be determined by ordering the identifiers from large to small.

2) A relative position of the plurality of first SRS resource sets in a first SRS resource set sequence and a relative position of the plurality of second SRS resource sets in a second SRS resource set sequence.

The example can determine the association relationship according to the relative positions of the SRS resource sets in the corresponding SRS resource set sequence.

For example, the first SRS resource set sequence includes SRS resource set 1 and SRS resource set 2, the SRS resource set 1 is located at the front, the SRS resource set 2 is located at the back, the second SRS resource set sequence includes SRS resource set 3 and SRS resource set 4, the SRS resource set 3 is located at the front, the SRS resource set 4 is located at the back, then SRS resource set 3 is associated with SRS resource set 1, and SRS resource set 4 is associated with SRS resource set 2.

Example two: and (4) predefined association relation.

1) The second target SRS resource set is associated with the first target SRS resource set identified as the smallest in the first sequence of SRS resource sets.

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) that is the smallest identifier in the first SRS resource set sequence.

2) The second target SRS resource set is associated with a first one of the first target SRS resource sets in a first SRS resource set sequence.

For example, the first sequence of SRS resource sets includes SRS resource set 1 and SRS resource set 2, the SRS resource set 1 is located at the front and the SRS resource set 2 is located at the back, the second sequence of SRS resource sets 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) located at the front in the first sequence of SRS resource sets.

This embodiment may implement TRP 1-oriented multi-TRP scheduling of the second DCI format, for example, the first SRS resource set sequence includes an SRS resource set 1 (corresponding to TRP 1) and an SRS resource set 2 (corresponding to TRP 2), and when the second target SRS resource set is associated with the 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 by the second DCI format may be sent to TRP1.

Example three: explicitly indicated associations.

1) The same SRS resource set association is identified.

For example, 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 (i.e., the second target SRS resource set) of the second SRS resource set sequence is associated with SRS resource set 1 (i.e., the first target SRS resource set) of the first SRS resource set sequence, and SRS resource set 2 (i.e., the second target SRS resource set) of the second SRS resource set sequence is associated with SRS resource set 2 (i.e., the first target SRS resource set) of the first SRS resource set sequence.

2) A first parameter carried within a set of SRS resources, the first parameter for indicating a set of SRS resources associated with the set of SRS resources.

The set of SRS resources referred to herein may include a first set of target SRS resources and a second set of target SRS resources.

Optionally, the first parameter satisfies at least one of:

1) The first parameter is an SRS resource set identification.

2) The first parameter is used to indicate that the SRS resource set is associated with a few SRS resources in a corresponding SRS resource set sequence.

Optionally, on the basis of any one of the embodiments introduced above, the method further comprises: the terminal receives a Media Access Control Element (MAC CE); and the terminal updates 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, the first and second liquid crystal display panels may be,

and the terminal updates path loss reference signals of all SRS resources in the first target SRS resource set according to the MAC CE.

In this embodiment, since the first target SRS resource set and the second target SRS resource set are associated, and the first target SRS resource set and the second target SRS resource set may include partially or completely the same SRS resource, the MAC CE updates path loss reference signals corresponding to all SRS resources in the first target resource set, and then path loss reference signals associated with SRS resources in the second target SRS resource set are updated at the same time.

In one example, the MAC CE includes a pathloss reference signal identifying a pathloss reference signal associated with an identification for updating the first set of target SRS resources and a pathloss reference signal associated with an identification of the second set of target SRS resources associated with the first set of target SRS resources; or, a pathloss reference signal included by the MAC CE identifies a pathloss reference signal associated with an identity used to update the second set of target SRS resources and a pathloss reference signal associated with an identity of the first set of target SRS resources associated with the second set of target SRS resources.

For example, the first SRS resource set is configured with two SRS resource sets 1 and 2, the second SRS resource set is configured with two SRS resource sets 3 and 4, SRS resource set 3 is configured based on SRS resource set 1, SRS resource set 4 is configured based on SRS resource set 2, and 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 also updated to the path loss reference signal indicated by the path loss reference signal index in the MAC CE. Then, when the index of SRS resource set 4 is carried in the MAC CE, the path loss reference signal of SRS resource set 2 corresponding to the index of SRS resource set 4 is also updated to the path loss reference signal indicated by the path loss reference signal index in the MAC CE.

In this embodiment, the MAC CE may include an identifier of any one of the correlated target SRS resource sets, and then the pathloss reference signal identifier included in the MAC CE is used to update the pathloss reference signals correlated to all the correlated target SRS resource sets.

In this embodiment, the MAC CE may simultaneously include an identifier of a plurality of target SRS resource sets and an identifier of at least one path loss reference signal, where the path loss reference signal identifier is used to update a path loss reference signal associated with an SRS resource set corresponding to the plurality of target SRS resource sets.

In another example, the MAC CEs include a first MAC CE and a second MAC CE; wherein a path loss reference signal included by the first MAC CE identifies a path loss reference signal used for updating the first target SRS resource set association; the second MAC CE includes a pathloss reference signal identification for updating a pathloss reference signal associated with the second set of target SRS resources.

In this embodiment, for target SRS resource sets associated with each other, a terminal receives multiple MAC CEs and updates path loss reference signals associated with the multiple target SRS resource sets at the same time.

In the foregoing embodiments, the determining, by the terminal, the transmission parameter of the SRS resource according to the configuration information includes: and the terminal determines the transmission parameters of the SRS resources according to the configuration information and the path loss reference signal indicated by the MAC CE.

Optionally, on the basis of any one of the embodiments described above, the method further includes: the terminal receives a third DCI of a third DCI format, wherein the third DCI format is the first DCI format or the second DCI format; and the terminal determines the transmission parameter of the PUSCH according to 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.

Optionally, the determining, by the terminal, the power control parameter set sequence of the PUSCH according to the third SRS resource set includes:

1) The terminal takes a power control parameter set sequence corresponding to the third SRS resource set as a power control parameter set sequence of the PUSCH; or
