Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority from a Chinese patent application filed with the China Patent Office on April 6, 2021, bearing application number 202110368544.3, and entitled "Method and apparatus for determining reference signal transmission position indication," the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to the field of wireless communication technology, and in particular to a method and apparatus for determining a reference signal transmission position indication. [Background technology]

[0003] In current wireless communication systems, an aperiodic sounding reference signal (SRS) (hereinafter, the aperiodic SRS is denoted as AP-SRS, and the Aperiodic-Sounding Reference Signal) is triggered by downlink control information (DCI) in a downlink control channel (Physical Downlink Control CHannel, PDCCH). One DCI for triggering the AP-SRS can simultaneously trigger one or more SRS resource sets. Each SRS resource set includes one or more SRS resources.

[0004] In 3GPP (registered trademark, same as below) New Radio (NR) systems Rel-15 and Rel-16, after receiving DCI that triggers AP-SRS in slot n, user equipment (UE) transmits AP-SRS in slot n.

[0005] To increase the flexibility of aperiodic SRS triggering, the 3GPP NR system uses the following method to determine the slot in which the AP-SRS is transmitted: The AP-SRS resource set is transmitted in the (t+1)th available slot (where the value of t is 0) from the reference slot. The available slot of the SRS resource set satisfies the following two conditions: The time difference between the transmission time of any SRS resource in the SRS resource set and the transmission time of the PDCCH that triggers the SRS resource set satisfies the minimum transmission time requirements of the PDCCH and AP-SRS that trigger the AP-SRS. The time domain positions of all SRS resources in the SRS resource set are uplink symbols or flexible symbols in the slot (i.e., the time domain positions of any SRS resources in the SRS resource set are not downlink symbols in the slot).

[0006] In the above implementation, RRC signaling can configure an SRS resource set with a set of t values ​​(assuming the number of values ​​is N, where N is equal to or greater than 1). The network side indicates the selected value of t to the UE.

[0007] The aperiodic downlink reference signal (e.g., Channel State Information- Reference Signal (CSI-RS), Channel State Information-Interference Measurement (CSI-IM), etc.) in the related art has the same transmission mechanism as the above aperiodic uplink AP-SRS. Currently, in the solution of aperiodic reference signal transmission position indication, when the aperiodic reference signal resource set is large, the overhead of the DCI field for transmitting the position is very large, and the increase in the overhead of the Physical Downlink Shared CHannel (PDSCH) affects the demodulation performance of the PDSCH. Summary of the Invention [Problem to be solved by the invention]

[0008] The embodiments of the present invention provide a method and apparatus for determining a transmission position indication of a reference signal (RS), which solves the problem in the related art that when there are many aperiodic reference signal resource sets, the overhead of the DCI field for transmitting the position is very large, and the increase in the overhead of the PDSCH overhead affects the demodulation performance of the PDSCH.

[0116] The term "and / or" in the embodiments of the present invention describes the related relationship of related objects, for example, indicates that there may be three kinds of relationships, A and / or B, which can represent A alone, both A and B, and B alone. The character " / " generally indicates an "or" relationship between the related object and the related object.

[0117] The term "plurality" in the embodiments of the present invention means two or more, and similarly other quantifiers.

[0118] To increase the flexibility of AP-SRS triggering, the 3GPPNR system uses the following method in Rel-17 to determine the slot for transmitting AP-SRS: The aperiodic SRS resource set is transmitted in the (t+1)th available slot from the reference slot (t is a slot offset value, which can be 0). For aperiodic downlink reference signals (e.g., CSI-RS, CSI-IM, etc.), similar to the above aperiodic uplink AP-SRS transmission mechanism, the method for determining the reference slot in the (t+1)th available slot from the reference slot for the aperiodic downlink reference signal can be defined by consensus.

[0119] After the base station configures the aperiodic RS resource for the UE, the method of configuring and indicating the slot offset value corresponding to the aperiodic RS resource to the UE may affect the overhead of the DCI. If multiple slot offset values ​​are configured for the aperiodic RS, when there are many triggered aperiodic RSs, the DCI field overhead becomes very large because the transmission position is indicated in the conventional manner. The increase in PDSCH overhead affects the demodulation performance of the PDSCH.

[0120] In view of this, some embodiments of the present invention provide a solution for indicating and determining RS transmission positions, which can indicate RS resource transmission positions with less DCI signaling, and increase the flexibility of RS resource triggering and transmission.

[0125] The solutions in the embodiments of the present invention shall be clearly and integrally described in combination with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all the embodiments. Other embodiments obtained by those skilled in the art without performing creative activities based on the embodiments of the present invention belong to the scope of the present invention.

[0126] EMBODIMENT 1 The method for indicating an RS transmission position provided by the embodiment of the present invention is applied to a network side device, and as shown in FIG. 2, the method includes the following steps:

[0127] Step S201: Indicate at least one set of time unit offset values ​​corresponding to each configured RS resource to a UE.

[0128] The RS resource may be an aperiodic RS resource, a semi-persistent RS resource, or a periodic RS resource. The types of RS resource may include, but are not limited to, an SRS resource, a CSI-RS resource, a CSI-IM resource, etc. Examples of the aperiodic RS resource include, but are not limited to, an uplink aperiodic RS resource or a downlink aperiodic RS resource. The uplink aperiodic RS resource may include, but is not limited to, an aperiodic SRS resource. The downlink aperiodic RS resource may include, but is not limited to, an aperiodic CSI-RS resource, an aperiodic CSI-IM resource. The RS resource according to the embodiment of the present invention may be any of the aforementioned resources.

[0129] Step S202: Trigger at least one of the RS resources by a DCI, and send first indication information through the DCI.

[0130] An association relationship between a first time unit offset value corresponding to each RS resource in the at least one RS resource and a set of first time unit offset values ​​corresponding to each RS resource is indicated by the same first indication information, where the first time unit offset value is a time unit offset value corresponding to a transmission position of each RS resource, and the set of first time unit offset values ​​is a set of time unit offset values.

[0131] In this embodiment, the first indication information indicates a first time unit offset value of each RS resource in the at least one RS resource by indicating an association relationship between a first time unit offset value corresponding to each RS resource in the at least one RS resource and a set of first time unit offset values ​​corresponding to each RS resource, and by indicating the first time unit offset value of each RS resource in the at least one RS resource, a UE is able to determine a time domain transmission position of each RS resource according to the first time unit offset value.

[0132] For RS resources that are triggered by the DCI of the present invention and require transmission position indication, the first indication information indicates the association relationship between the first time unit offset value corresponding to the RS resource and the set of first time unit offset values ​​corresponding to each RS resource, so that the transmission position of the RS resource can be indicated with less DCI signaling, and the flexibility of the triggering and transmission of the RS resource is improved.

[0133] The first indication information is in a designated information field of the DCI. Different values ​​of the designated information field can be used to represent different first indication information.

[0134] In an embodiment of the present invention, a certain state of the specification information field of the DCI indicates that the first slot time unit value indicates an offset value of a slot unit in the first set of time unit offset values, and the DCI indicates an association relationship between the first slot time unit value and the first set of time unit offset values.

[0135] If the time unit is a slot, the time unit offset can be expressed as a slot offset.

[0136] Optionally, the DCI's specification information field includes, but is not limited to, at least one of the following: (1) A slot offset information field indicating the slot offset value of the RS resource triggered by the DCI.

[0137] (2) Modulation and coding scheme (MCS) indication field. A part of the state of the MCS indication field indicates the modulation and coding scheme of the data scheduled by the DCI, and a part of the state indicates the time unit offset value.

[0138] (3) An SRS request field, which triggers the at least one RS resource to be synchronized and indicates the RS slot offset value.

[0139] When the specification information field of the DCI includes a slot offset information field and an MCS indication field indicating a slot offset value of the RS resource triggered by the DCI, the MCS indication field and the slot offset information field combine to indicate the time domain location of the RS resource and the associated relationship according to the indicated information.

[0140] In this embodiment, optionally, the DCI triggers the RS resource by triggering an RS resource set associated with the RS resource. That is, when the DCI triggers a specific RS resource set, the RS resource associated with the RS resource set is triggered. Optionally, one RS resource is associated with one RS resource set, which means that the RS resource is configured in the RS resource set.

[0141] Optionally, the DCI triggers some other RS ​​resources except the at least one RS resource, and the other RS ​​resources triggered by the DCI are configured with only one corresponding time unit offset value or are configured with no time unit offset value.

[0142] Optionally, the at least one RS resource includes a plurality of RS resources, and the association relationship between the first time unit offset value corresponding to each RS resource in the at least one RS resource and the set of first time unit offset values ​​corresponding to each RS resource is the same, and the first indication information indicates one association relationship. Each RS resource in the at least one RS resource can indicate the association relationship between the first time unit offset value corresponding to each RS resource and the set of first time unit offset values ​​corresponding to each RS resource through one first indication information.

[0143] Optionally, the time unit is a slot or a sub-slot or a symbol.

[0144] Optionally, the association relationship between the first time unit offset value and the set of first time unit offset values ​​includes at least one of the following: (1) The first time unit offset value is a time unit offset value at a first position in a first set of time unit offset values, the first position being a position indicated by the first indication information.

[0145] A first time unit offset value at a first position in the set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information. If the first indication information indicates an associated relationship, the first time unit offset value at the same position in the set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information.

[0146] The first time unit offset value is a time unit offset value at a first position in the first set of time unit offset values ​​and includes at least one of the following: (i) The first time unit offset value is a time unit offset value whose sequence in the set of first time unit offset values ​​is a first sequence, the first sequence being a sequence indicated by the first indication information.

[0147] Assuming that the time unit is a slot, the network side device configures a set of slot offset values ​​for three RS resources, and the sets of slot offset values ​​are {0,1,2,3}, {1,2}, and {2,3,4,5}, respectively. These three RS resources are triggered by DCI. If the first indication information included in the DCI indicates that the sequence number is 2, the slot offset values ​​corresponding to the three RS resources are 1, 2, and 3, respectively.

[0148] (ii) a first time unit offset value is a time unit offset value corresponding to a first sequence number in a first set of time unit offset values, the first sequence number being a sequence number indicated by the first indication information;

[0149] When the network side device configures different time unit offset values ​​for the same sequence number in the RS resource, the UE can transmit different RS resources on the positions of different time unit offset values. The sequence number may be a function of the sequence n=mk, where n is the sequence, m is the sequence number, and k is a natural number smaller than m (the position of the initial time unit offset value is 1), or k is a natural number smaller than m (the position of the initial time unit offset value is 0). Assume that the time unit is a slot, and the position of the initial slot offset value is 1. The set of slot offset values ​​is the sequence n=m-1, and the network side device configures a set of slot offset values ​​for three RS resources, and the sets of slot offset values ​​are {0,1,2,3},{1,2},{2,3,4,5}, respectively. These three RS resources are triggered by DCI. If the first indication information included in the DCI indicates that the sequence number is 2, the slot offset values ​​corresponding to the three RS resources are 0, 1, and 2, respectively.

[0150] (2) The first time unit offset value is a time unit offset value associated with a first trigger state in the first set of time unit offset values, the first trigger state being a trigger state indicated by the first indication information.

[0151] Optionally, the first time unit offset value is predetermined as a time unit offset value associated with a first trigger condition in a first set of time unit offset values. The first indication is indicative of the first trigger condition.

[0152] When the first indication information indicates an association relationship, a first time unit offset value of a first trigger state in a set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information. Assuming that the time unit is a slot, the network side device sets a set of slot offset values ​​{2, 5, 4} for RS resource 1. Here, trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. When the first indication information is trigger state 2, it is used to indicate that the slot offset value is 5.

[0153] (3) The first time unit offset value is a time unit offset value whose identifier in the set of first time unit offset values ​​is a first identifier, and the first identifier is an identifier indicated by the first indication information.

[0154] When the first indication information indicates an association relationship, a first time unit offset value of a first trigger state in a set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information. Assuming that the time unit is a slot, a set of slot offset values ​​configured by the network side device for one RS resource is {0, 1, 2, 3}. The corresponding identifiers are {2, 1, 3, 0}. The RS resource is triggered by a DCI. If the identifier indicated by the first indication information included in the DCI is 0, the slot offset value corresponding to the RS resource is 3.

[0155] The association relationship indicated by the first instruction information may be a combination of the association relationships described above. Specifically, the second type of association relationship may be combined with any other association relationship. For example, when the second type of association relationship is combined with the first type of association relationship, the first instruction information may determine a first time unit offset value at a first position in a first trigger state in a set of first time unit offset values ​​corresponding to each RS resource. Assuming that the time unit is a slot, the slot offset values ​​configured by the network side device for the RS resource are {0, 1, 2, 3} corresponding to trigger state 1, {1, 2} corresponding to trigger state 2, and {2, 3, 4, 5} corresponding to trigger state 3. When the DCI triggers the RS resource under trigger state 2, the first instruction information included in the DCI indicates a slot offset value whose sequence in trigger state 2 is 2, and the slot offset value corresponding to the RS resource is 2.

[0156] Optionally, the first indication indicates that an association relationship between the first time unit offset value and the set of first time unit offset values ​​includes at least one of the following: The first instruction indicates that the first time unit offset value is a time unit offset value at a first position in a first set of time unit offset values, or a pre-agreed that the first time unit offset value is a time unit offset value at a first position indicated by the first instruction in a first set of time unit offset values. The first instruction indicates the first position.

[0157] The first instruction indicates that the first time unit offset value is a time unit offset value associated with a first trigger condition in a first set of time unit offset values, or a pre-agreed that the first time unit offset value is a time unit offset value associated with a first trigger condition indicated by the first instruction in a first set of time unit offset values. The first instruction indicates the first trigger condition.

[0158] The first indication information indicates that the first time unit offset value is a time unit offset value whose identifier in the first set of time unit offset values ​​is a first identifier, or it is pre-agreed that the first time unit offset value is a time unit offset value of a first identifier indicated by the first indication information in the first set of time unit offset values. The first indication information indicates the first identifier.

[0159] The pre-agreed manner may be pre-agreed according to a protocol, and may be that the network side device transmits second indication information to the UE, where the second indication information indicates that a first time unit offset value is a time unit offset value of the first location / first trigger state / first identifier indicated by the first indication information in a set of first time unit offset values.

[0160] When the second indication information is transmitted, the step of transmitting the second indication information may precede the step of "triggering at least one RS resource in the RS resources by a DCI and transmitting first indication information via the DCI."

[0161] Optionally, the first instruction indicates that the first time unit offset value is a time unit offset value at a first position in the first set of time unit offset values, or it is pre-agreed that the first time unit offset value is a time unit offset value at a first position indicated by the first instruction in the first set of time unit offset values. The first instruction indicates the first position by any of the following:

[0162] The first instruction information indicates that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence, and the information indicates that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence or that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence indicated by the first instruction information, and the first instruction information indicates the first sequence.

[0163] The first indication information indicates that the first time unit offset value is a time unit offset value corresponding to a first sequence number in a first set of time unit offset values, or pre-agreed that the first time unit offset value is a time unit offset value corresponding to a first sequence number indicated by the first indication information in a first set of time unit offset values, the first indication information indicating the first sequence number.

[0164] The network side device transmits configuration information to the UE to indicate at least one set of time unit offset values ​​corresponding to the RS resources to the UE. Indicating at least one set of time unit offset values ​​corresponding to the RS resources to the UE is also referred to as configuring at least one set of time unit offset values ​​corresponding to the RS resources for the UE. When the network side device configures at least one set of time unit offset values ​​corresponding to the RS resources for the UE, the RS resources are multiple. The configuration method used is as follows:

[0165] Configuration method 1: for at least one RS resource in the RS resources, configure at least one set of time unit offset values ​​corresponding to each RS resource;

[0166] The network side device configures the RS sources with time unit offset values ​​individually, for example, configures a set of slot offset values ​​{0, 1, 2, 3} for RS resource 1, configures a set of slot offset values ​​{1, 2} for RS resource 2, and configures a set of slot offset values ​​{2, 3, 4, 5} for RS resource 3.

[0167] Configuration method 2: Configuring at least one first RS resource in the RS resource and at least one corresponding set of time unit offset values ​​for the RS resource set associated with each first RS resource.

[0168] When an RS resource is associated with an RS resource set, it means that the RS resource is included in the RS resource list configured in the RS resource set. One RS resource can be configured in multiple RS resource lists, that is, one RS resource is associated with multiple RS resource sets.

[0169] The first RS resource is an associated RS resource set, where the associated RS resource set is composed of RS resources of at least one set of time unit offsets, and a first RS resource set associated with a first RS resource is an RS resource set associated with at least one of the first RS resources and composed of at least one set of time unit offset values.

[0170] Optionally, indicating at least one set of time unit offset values ​​corresponding to RS resources to the UE specifically includes: Indicate to the UE at least one set of time unit offset values ​​corresponding to a first RS resource set associated with a first RS resource in the RS resources, the first RS resource being an associated RS resource set, the associated RS resource set being composed of RS resources of at least one set of time unit offsets, and the first RS resource set being an RS resource set associated with at least one of the first RS resources and composed of at least one set of time unit offset values.

[0171] The at least one RS resource includes at least one first RS resource, a first time unit offset value corresponding to the first RS resource is a second time unit offset value corresponding to a first RS resource set associated with the first RS resource, and a set of first time unit offset values ​​corresponding to the first RS resource is a set of second time unit offset values ​​corresponding to the first RS resource set associated with the first RS resource.

[0172] The first indication information indicates an association relationship between second time unit offset values ​​corresponding to at least a portion of first RS resource sets associated with each first RS resource in the at least one first RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set.

[0173] Wherein, in some embodiments, indicating at least one set of time unit offset values ​​corresponding to each configured RS resource to the UE comprises: The method includes indicating at least one set of time unit offset values ​​corresponding to a first RS resource set to which the first RS resource belongs among the RS resources to the UE.

[0174] An association relationship between a second time unit offset value corresponding to the first RS resource set and a set of second time unit offset values ​​corresponding to the first RS resource set is indicated by first indication information, where the second time unit offset value is a time unit offset value corresponding to a transmission position of the first RS resource set, and the set of second time unit offset values ​​is a set of time unit offset values ​​corresponding to the first RS resource set.

[0175] For example, the network side device configures a time unit offset value for a first RS resource according to an associated first RS resource set, e.g., RS resource 1, RS resource 2 and RS resource 3 are configured in the RS resource list of RS resource set set 1, RS resource 4 and RS resource 5 are configured in the RS resource list of RS resource set set 2, set 1 is configured with a set of slot offset values ​​{0, 1, 2, 3}, and set 2 is configured with a set of slot offset values ​​{1, 2}.

[0176] Optionally, when the network side device configures a time unit offset value for a first RS resource according to an associated first RS resource set, the first time unit offset value corresponding to the first RS resource is a second time unit offset value corresponding to the first RS resource set associated with the first RS resource, and the set of first time unit offset values ​​corresponding to the first RS resource is a set of second time unit offset values ​​corresponding to the first RS resource set associated with the first RS resource.

[0177] The first indication information indicates an association relationship between second time unit offset values ​​corresponding to at least a portion of first RS resource sets associated with each first RS resource in the at least one first RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set.

[0178] Optionally, at least a portion of the first RS resource sets associated with one first RS resource are first RS resource sets associated with the first RS resource and triggered by the DCI.

[0179] In the above-mentioned embodiment, the first instruction information indicates an association relationship between a second time unit offset value corresponding to at least a portion of first RS resource sets associated with each first RS resource in the at least one first RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set, thereby indicating an association relationship between a first time unit offset value of each first RS resource in the at least one first RS resource and a set of first time unit offset values ​​corresponding to the first RS resource.

[0180] For example, when a set of slot offset values ​​{0, 1, 2, 3} is configured in set1 and a set of slot offset values ​​{1, 2} is configured in set2, when RS resource 4 and RS resource 5 are triggered by DCI to indicate slot offset value 2, the first indication information indicates the association relationship between the slot offset value 2 in set2 and {1, 2}.

[0181] Optionally, the method according to this embodiment includes: The first RS resource in the at least one RS resource includes a plurality of first RS resources; an association relationship between each first RS resource set associated with a first RS resource in the at least one RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set is the same; The first indication information indicates one association relationship.

[0182] For each first RS resource set associated with a first RS resource among the at least one RS resource, one first indication information indicates an association relationship between a second time unit offset value corresponding to each first RS resource set and a set of second time unit offset values ​​corresponding to each first RS resource set.

[0183] Optionally, the association relationship between the second time unit offset value and the set of second time unit offset values ​​includes at least one of the following: (1) The second time unit offset value is a time unit offset value at a first position in the set of second time unit offset values, the first position being a position indicated by the first indication information.

[0184] The first indication information can determine a second time unit offset value at a first position in a set of second time unit offset values ​​corresponding to each first RS resource set associated with the first RS resource. If the first indication information indicates an associated relationship, the first indication information can determine a second time unit offset value at the same position in the set of second time unit offset values ​​corresponding to each first RS resource set associated with the first RS resource.

[0185] The second time unit offset value is a time unit offset value at a first position in the set of second time unit offset values ​​and includes at least one of the following: (i) The second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence, the first sequence being a sequence indicated by the first indication information.

[0186] Assuming that the time unit is a slot, a set of slot offset values ​​configured by the network side device for the three RS resource sets are {0, 1, 2, 3}, {1, 2}, and {2, 3, 4, 5}. When the RS resources in these three RS resource sets are triggered by a DCI and the first indication information included in the DCI indicates that the sequence number is 2, the slot offset values ​​corresponding to the RS resources in the three RS resource sets are 1, 2, and 3, respectively.

[0187] (ii) the second time unit offset value is a time unit offset value corresponding to a first sequence number in the set of second time unit offset values, the first sequence number being a sequence number indicated by the first indication information;

[0188] When the time unit offset value configured by the network side device for each RS resource set is different for the same sequence number, the UE can transmit the RS resource set at different time unit offset positions. The sequence number may be a function of the sequence n=mk, where n is the sequence, m is the sequence number, and k is a natural number smaller than m (the position of the initial time unit offset value is set to 1), or k is a natural number smaller than m (the position of the initial time unit offset value is set to 0). Assume that the time unit is a slot, and the position of the initial slot offset value is set to 1. The set of slot offset values ​​has a sequence n=m-1, and the set of slot offset values ​​configured by the network side device for the three RS resource sets are {0, 1, 2, 3}, {1, 2}, and {2, 3, 4, 5}, respectively. When the three RS resource sets are triggered by DCI, and the first indication information included in the DCI indicates that the sequence number is 2, the slot offset values ​​corresponding to the three RS resource sets are 0, 1, and 2, respectively.

[0189] (2) The second time unit offset value is a time unit offset value associated with a first trigger state in the set of second time unit offset values, the first trigger state being a trigger state indicated by the first instruction information.

[0190] When the first indication information indicates an association relationship, the first indication information can determine a second time unit offset value of the first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set. Assuming that the time unit is a slot, the network side device configures a set of slot offset values ​​{2, 5, 4} for RS resource set 1. Here, trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. When the first indication information indicates trigger state 2, it is used to indicate that the slot offset value is 5.

[0191] (3) The second time unit offset value is a time unit offset value whose identifier in the set of second time unit offset values ​​is a first identifier, and the first identifier is an identifier indicated by the first indication information.

[0192] When the first indication information indicates an association relationship, the first indication information can determine a second time unit offset value of the first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set. Assuming that the time unit is a slot, a set of slot offset values ​​configured by the network side device for one RS resource set are {0, 1, 2, 3}, respectively, and the corresponding identifiers are {2, 1, 3, 0}. When the RS resource of the RS resource set is triggered by DCI and the identifier indicated by the first indication information included in the DCI is 0, the slot offset value corresponding to the RS of the RS resource set is 3.

[0193] Regarding the above-mentioned association relationship and indication manner, optionally, the association relationship between the first indication information indicating the second time unit offset value and the set of second time unit offset values ​​includes at least one of the following: (1) The first instruction information indicates that the second time unit offset value is a time unit offset value at a first position in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value at a first position indicated by the first instruction information within a second set of time unit offset values, and the first instruction information indicates the first position.

[0194] (2) The first instruction information indicates that the second time unit offset value is a time unit offset value associated with a first trigger condition in a second set of time unit offset values, or it is agreed in advance that the second time unit offset value is a time unit offset value associated with a first trigger condition indicated by the first instruction information in the second set of time unit offset values, and the first instruction information indicates the first trigger condition.

[0195] (3) The first instruction information indicates that the second time unit offset value is a time unit offset value whose identifier in the set of second time unit offset values ​​is a first identifier, or it is pre-agreed that the second time unit offset value is a time unit offset value corresponding to the first identifier indicated by the first instruction information in the set of second time unit offset values, and the first instruction information indicates the first identifier.

[0196] The pre-agreed manner is pre-agreed upon according to a protocol, and the network side device may also transmit one third indication information to the UE, where the third indication information indicates that the second time unit offset value is a time unit offset value in a set of second time unit offset values ​​corresponding to the first position / first trigger state / first identifier indicated by the first indication information.

[0197] If the third instruction information is transmitted, the step of sending the third instruction information may be prior to step S202 of "triggering at least one RS resource within the RS resources by a DCI and sending first instruction information via the DCI" and "triggering at least one RS resource within the RS resources by a DCI and sending the first instruction information via the DCI".

[0198] Optionally, the third instruction information is the same instruction information as the second instruction information.

[0199] Optionally, the first instruction indicates that the second time unit offset value is a time unit offset value at a first position in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value at a first position indicated by the first instruction within a second set of time unit offset values. The first instruction indicates the first position by any of the following:

[0200] (1) The first instruction information indicates that the second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence, or it is pre-agreed that the second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence indicated by the first instruction information, and the first instruction information indicates the first sequence.

[0201] (2) The first indication information indicates that the second time unit offset value is a time unit offset value corresponding to a first sequence number in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value corresponding to a first sequence number indicated by the first indication information in a second set of time unit offset values, and the first indication information indicates the first sequence number.

[0202] The association relationship indicated by the first instruction information may be a combination of the association relationships described above. Specifically, the second type of association relationship may be combined with any other association relationship. For example, when the second type of association relationship is combined with the first type of association relationship, the first instruction information may determine a second time unit offset value at a first position in a first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set. Assuming that the time unit is a slot, the slot offset values ​​configured by the network side device for the network RS resource set are {0, 1, 2, 3} corresponding to trigger state 1, {1, 2} corresponding to trigger state 2, and {2, 3, 4, 5} corresponding to trigger state 3. When the RS resource of the RS set is triggered by DCI in trigger state 2, the first instruction information included in the DCI indicates a slot offset value whose sequence is 2 in trigger state 2, and the slot offset value corresponding to the RS resource in the RS resource set is 2.

[0203] When the network side device indicates at least one set of time unit offset values ​​corresponding to RS resources, all RS resources may be configured using the above configuration method 1, or all RS resources may be configured using the above configuration method 2; or some RS resources may be configured using the above configuration method 1, and some RS resources may be configured using the above configuration method 2.

[0204] As an optional embodiment, the network side device indicates to the UE at least one set of time unit offset values ​​corresponding to RS resources, specifically, For at least some of the RS resources, at least one set of time unit offset values ​​corresponding to each RS resource are individually configured.

[0205] If the network side device determines that all RS resources need to be configured, it configures at least one set of time unit offset values ​​corresponding to each RS resource individually, and the number of configured time unit offset values ​​may be the same or different. Alternatively, if the network side device determines that some RS resources use pre-agreed time offset values, it configures at least one set of time unit offset values ​​corresponding to each RS resource individually for some RS resources, and the number of configured time unit offset values ​​may be the same or different.

[0206] The at least one set of time unit offset values ​​corresponding to each RS resource configured for the UE by the network side device may include at least one set of time unit offset values ​​applicable to all trigger conditions, and may include at least one set of time unit offset values ​​corresponding to at least some of the trigger conditions.

[0207] As an optional embodiment, for at least some of the RS resources, separately configuring at least one set of time unit offset values ​​corresponding to each RS resource can specifically include: For at least one RS resource among the at least some of the RS resources, at least one set of time unit offset values ​​corresponding to each of the at least some trigger conditions of each RS resource are individually configured.

[0208] This scheme establishes a relationship between the trigger state of RS resources and the RS time domain transmission positions, so that more combinations of RS resource time domain transmission positions can be indicated via DCI with the same DCI overhead as the previous scheme.

[0209] As an optional embodiment, for at least one RS resource among at least a portion of the RS resources, at least one set of time unit offset values ​​corresponding to each RS resource in every trigger state are individually configured.

[0210] When at least one set of time unit offset values ​​corresponding to at least some of the trigger states of each RS resource is individually configured, a set of time unit offset values ​​corresponding to each of the at least some of the trigger states may be configured for each of the RS resources. Optionally, a set of time unit offset values ​​corresponding to each of the RS resources in each of the trigger states of the some of the trigger states is configured. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5} is configured for RS resource 1, where trigger state 1 corresponds to lot offset value 2, and trigger state 2 corresponds to slot offset value 5. Optionally, a set of time unit offset values ​​corresponding to each of the RS resources in all of the trigger states is configured. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for RS resource 1, where trigger state 1 corresponds to lot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. For example, if RS resource 1 has three trigger states and one slot offset value (1, 2, and 3, respectively) is configured for each trigger state for RS resource 1, then a set of slot offset values ​​corresponding to each trigger state configured for RS resource 1 is {1, 2, 3}.

[0211] A set of time unit offset values ​​corresponding to each of the trigger states of at least some of the states may be configured for the RS resources. Optionally, a set of time unit offset values ​​corresponding to each of the trigger states of the at least some of the states may be configured for the RS resources. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource 1. A set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource 1. Optionally, a set of time unit offset values ​​corresponding to each of the trigger states of all of the trigger states may be configured for the RS resources. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource 1, a set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource 1, and a set of slot offset values ​​{0, 3, 4} is configured for trigger state 3 of RS resource 1.

[0212] Optionally, the first set of time unit offset values ​​corresponding to at least one of the RS resources includes at least one of the following: (1) A set of time unit offset values ​​corresponding to each trigger state configured in the RS resource.

[0213] (2) A set of time unit offset values, including all time unit offset values ​​corresponding to a first trigger state configured on the RS resource, where the first trigger state is a trigger state corresponding to when the DCI triggers the RS resource.

[0214] When a network side device configures a time unit offset value for at least one RS resource using configuration method 2, the RS resource for which the time unit offset value is configured includes at least one first RS resource, and the corresponding at least one set of time unit offset values ​​configured in a first RS resource set associated with each first RS resource includes at least one set of time unit offset values ​​applicable to all trigger states and may include at least one set of time unit offset values ​​corresponding to at least some of the trigger states.

[0215] Optionally, configure a time unit offset value for an RS resource set. When a first RS resource is associated with an RS resource set, a set of time unit offset values ​​configured for the RS resource set is also a set of time unit offset values ​​configured for the RS resource set.

[0216] As an optional embodiment, the RS resources indicated to the UE include a plurality of first RS resources, and indicating at least one set of time unit offset values ​​corresponding to the RS resources to the UE specifically includes: For first RS resource sets associated with at least some of the plurality of first RS resources, at least one set of time unit offset values ​​corresponding to each first RS resource set is individually configured.

[0217] In an alternative embodiment, the first RS resource set associated with at least some of the first RS resources includes a plurality of second RS resource sets, the second RS resource set being a part of the first RS resource set. At least one set of time unit offset values ​​corresponding to at least some associated trigger conditions are configured, and the at least some associated trigger conditions include the first RS resource set of the trigger conditions indicated by the DCI. For example, the triggered first RS resources include RS resource 1, RS resource 2, RS resource 3, RS resource 4, RS resource 5, RS resource 6, RS resource 7, where RS resource 1, RS resource 2, and RS resource 3 are associated with RS resource set 1, RS resource 4 and RS resource 5 are associated with RS resource set 2, and RS resource 5, RS resource 6, and RS resource 7 are associated with RS resource set 3, and one set configured for RS resource set 1 is applicable to the time unit offset values ​​of all trigger conditions. The two sets of time unit offset values ​​configured for RS resource set 2 are, respectively, one set of time unit offset values ​​corresponding to trigger state 1 and one set of time unit offset values ​​corresponding to trigger state 2. It is determined that the one set configured for RS resource set 1 is applicable to the time unit offset values ​​of all trigger states. It is determined to configure three sets of time unit offset values ​​for RS resource set 3, where the three sets include one set of time unit offset values ​​applicable to all trigger states, one set of time unit offset values ​​corresponding to trigger state 1, and one set of time unit offset values ​​corresponding to trigger state 2.

[0218] Optionally, individually configuring at least one set of time unit offset values ​​corresponding to each first RS resource set specifically includes individually configuring, for at least some of the plurality of second RS resource sets, at least one set of time unit offset values ​​corresponding to each of at least some of the trigger conditions corresponding to each of the second RS resource sets.

[0219] In an optional embodiment, when at least one set of time unit offset values ​​corresponding to at least some of the trigger conditions corresponding to each of the second RS resource sets is individually configured, a set of time unit offset values ​​corresponding to each of the trigger conditions is configured for the second RS resource sets. Optionally, a set of time unit offset values ​​corresponding to each of the trigger conditions among the some of the trigger conditions can be configured for each of the second RS resource sets. For example, RS resource set 1 has three trigger conditions, and a set of slot offset values ​​{2, 5} is configured for RS resource set 1, where trigger condition 1 corresponds to slot offset value 2 and trigger condition 2 corresponds to slot offset value 5. Optionally, a set of time unit offset values ​​corresponding to each of the trigger conditions among all the trigger conditions is configured for each of the second RS resource sets. For example, RS resource set 1 has three trigger states, and configures a set of slot offset values ​​{2, 5, 4} for RS resource set 1, where trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4.

[0220] When at least one set of time unit offset values ​​corresponding to at least some of the trigger states corresponding to each of the second RS resource sets is individually configured, optionally, one set of time unit offset values ​​corresponding to each of the trigger states among the some of the states is configured for each of the second RS resource sets. For example, RS resource set 1 has three trigger states, and one set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource set 1, and one set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource set 1. Alternatively, one set of time unit offset values ​​corresponding to each of the trigger states among all the trigger states may be configured for each of the second RS resource sets. For example, RS resource set 1 has three trigger states, and one set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource set 1, one set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource set 1, and one set of slot offset values ​​{0, 3, 4} is configured for trigger state 3 of RS resource set 1.

[0221] Optionally, the second set of time unit offset values ​​corresponding to at least one of the first RS resource sets includes at least one of the following: a set of time unit offset values ​​corresponding to each trigger condition configured in the second RS resource set; A set of time unit offset values ​​configured in the second RS resource set, the set consisting of all time unit offset values ​​corresponding to a first trigger condition.

[0222] Here, the first trigger state is a trigger state corresponding to when the DCI triggers the first RS resource set.

[0223] The second set of time unit offset values ​​corresponding to at least one second RS resource set is at least one set of time unit offset values ​​corresponding to the trigger state indicated by the DCI. For example, RS resource set 1 has three trigger states, and configures a set of slot offset values ​​{2, 5, 4} for trigger state 1 of RS resource set 1, configures a set of slot offset values ​​{0, 1, 2} for trigger state 2 of RS resource set 1, and configures a set of slot offset values ​​{0, 3, 4} for trigger state 3 of RS resource set 1. When DCI triggers RS resources in RS resource set 1 via trigger state 2, the set of second time unit offset values ​​corresponding to RS resource set 1 is {0, 1, 2}, and when the sequence indicated by the first indication information is 2, the corresponding second time offset value is 1.

[0224] When the network side device configures at least one set of time unit offset values ​​corresponding to each RS resource individually, for one RS resource using configuration method 1, among the at least one set of time unit offset values ​​configured for the RS resource, each set of time unit offset values ​​is applicable to all trigger states, and each set of time unit offset values ​​is applicable to the trigger state corresponding to the set, where the at least one set of time unit offset values ​​is applicable to all trigger states, and the at least one set of time unit offset values ​​is applicable to the trigger state corresponding to the set.

[0225] The network side device indicates to the UE at least one set of time unit offset values ​​corresponding to the RS resources in one of the following manners:

[0226] Manner 1: The network side indicates the configuration of RS resources and at least one corresponding set of time unit offset values ​​to the UE through RRC signaling.

[0227] Optionally, the network side indicates to the UE the configuration of one RS resource and at least one set of corresponding time unit offset values ​​by RRC signaling; specifically, the network side indicates to the UE the configuration of the RS resource, the configuration of an RS resource set associated with the RS resource, and at least one set of time unit offset values ​​corresponding to the RS resource set associated with the RS resource by RRC signaling.

[0228] Manner 2: The network side indicates the configuration of RS resources and at least one corresponding set of time unit offset values ​​to the UE via MAC-CE signaling.

[0229] Optionally, the network side indicates the configuration of RS resources and at least one corresponding set of time unit offset values ​​to the UE through MAC-CE signaling, specifically The network side indicates to the UE via MAC-CE signaling the configuration of the RS resource, the configuration of an RS resource set associated with the RS resource, and at least one set of time unit offset values ​​corresponding to the RS resource set associated with the RS resource.

[0230] Method 3: Indicate a configuration of RS resources and corresponding multiple time unit offset values ​​to a UE through RRC signaling, and indicate at least one set of time unit offset values ​​among the multiple time unit offset values ​​corresponding to at least some of the RS resources to the UE through MAC-CE signaling.

[0231] Selectively, indicating a configuration of one RS resource and a plurality of corresponding time unit offset values ​​to the UE by RRC signaling, and indicating at least one set of time unit offset values ​​among the plurality of time unit offset values ​​corresponding to the RS resource to the UE via MAC-CE signaling means, specifically, the network side indicating, to the UE by RRC signaling, a configuration of an RS resource set associated with the RS resource and a plurality of time unit offset values ​​corresponding to the RS resource set associated with the RS resource, and indicating at least one set of time unit offset values ​​among the plurality of time unit offset values ​​corresponding to the RS resource set associated with the RS resource to the UE via MAC-CE signaling.

[0232] Alternatively, the number of bits occupied by the first indication information in the DCI is a predefined fixed value, or the number of bits occupied by the first indication information in the DCI is determined based on the number of time unit offset values ​​included in each of the at least one set of time unit offset values. For example, the network side agrees with the UE that the first indication information occupies N bits (N is a positive integer) in the DCI. Usually, it has 1 bit, 2 bits, 3 bits, 4 bits, etc.

[0233] Optionally, the number of bits occupied by the first indication information in the DCI is determined based on the number of time unit offset values ​​included in each of the at least one set of time unit offset values, specifically, The number of bits occupied by the first indication information in the DCI is determined based on a maximum value of the number of time unit offset values ​​included in each of the at least one set of time unit offset values.

[0234] The number of bits occupied by the first indication information in the DCI is

number

number

number

[0235] Optionally, the network side device indicates to the UE, via RRC signaling or MAC-CE signaling, the number of bits occupied by the first indication information in the DCI.

[0236] Optionally, the aperiodic RS resource configured by the network side is the RS resource configured for the UE in one BWP / serving cell / frequency band.

[0237] Optionally, the set of time unit offset values ​​for the RS resource is configured in the following manner: (1) Configure the maximum time unit offset value of the RS resource.

[0238] A set of time unit offset values ​​corresponding to an RS resource is a time unit offset value from a minimum time unit offset value to a maximum time unit offset value by default. The maximum time unit offset value is indicated by DCI. Taking the time unit as a slot as an example, when a set of slot offset values ​​corresponding to RS resource 1 are {0, 1, 2, 3}, 0 is the minimum slot offset value by default. The network side device configures a set of slot offset values ​​corresponding to RS resource 1 by configuring a maximum slot value of 3 for the RS resource 1.

[0239] Optionally, configuring the maximum time unit offset value of the RS resource specifically configures the maximum time unit offset value of an RS resource set associated with the RS resource, for example, by taking the RS resource as an SRS resource, configuring respective maximum time unit offset values ​​for one or more RS resource sets.

[0240] (2) Configuring minimum and maximum time unit offset values ​​for RS resources.

[0241] A set of time unit offset values ​​corresponding to an RS resource is a time unit offset value from a configured minimum time unit offset value to a configured maximum time unit offset value. The minimum time unit offset value and the maximum time unit offset value indicated by the DCI can be set in the DCI. Taking the time unit as an example of a slot, when a set of slot offset values ​​corresponding to an RS resource 1 are {2, 3, 4, 5, 6}, the network side device configures a set of slot offset values ​​corresponding to the RS resource 1 by configuring a minimum slot value of 2 and a maximum slot value of 6 for the RS resource 1.

[0242] Optionally, configuring the minimum and maximum time unit offset values ​​of the RS resource specifically configures the minimum and maximum time unit offset values ​​of an RS resource set associated with the RS resource, taking the RS resource as an example of an SRS resource, respectively configuring the minimum and maximum time unit offset values ​​for one or more RS resource sets.

[0243] (3) The DCI indicates the number of bits N occupied by the first indication information.

[0244] A set of time unit offset values ​​corresponding to RS resources is set by default from the minimum time unit offset value.

number

[0245] Alternatively, if at least one set of time unit offset values ​​corresponding to an RS resource is one or more sets of time unit offset values ​​corresponding to an RS resource set associated with the RS resource, the set of time unit offset values ​​corresponding to the RS resource set is set by default from the minimum time unit offset value.

number

[0246] (4) Indicates the number of bits N occupied by the first indication information in the DCI, constituting a minimum time unit offset value.

[0247] A set of time unit offset values ​​corresponding to an RS resource is calculated from the minimum time unit offset value configured.

number

[0248] Alternatively, if at least one set of time unit offset values ​​corresponding to an RS resource is one or more sets of time unit offset values ​​corresponding to an RS resource set associated with the RS resource, the set of time unit offset values ​​corresponding to the RS resource set is set by default from the minimum time unit offset value.

number

[0249] Next, when the network side device is used as a base station, the RS resource is a non-periodic SRS resource, the time unit is a slot, and the non-periodic SRS adopts configuration method 2 and configures the slot offset value as two corresponding examples.

[0250] Example 1 The base station transmits to the UE configuration information of the SRS resource set associated with the aperiodic SRS resource. For each SRS resource set, the base station configures at least one set of slot offset values. A set of slot offset values ​​includes one or more slot offset values.

[0251] The base station transmits a DCI to the UE for triggering aperiodic SRS resource transmission, the DCI includes first indication information for indicating a transmission slot of at least one SRS resource set triggered by the indication DCI, the first indication information indicates a sequence number, the sequence number indicating a sequence number of a slot offset value corresponding to an actual transmission slot of each SRS resource set triggered by the DCI among a plurality of slot offset values ​​respectively configured by the base station, that is, triggering each SRS resource set corresponding to the same sequence serial number, the sequence number m is a function of the sequence n, where n=m-1, please refer to the above description for details.

[0252] Take an example where a base station configures three aperiodic SRS resource sets for a UE through RRC signaling, the three aperiodic SRS resource sets are represented as SRS set 1, SRS set 2 and SRS set 3, respectively. Suppose that the slot offset values ​​of a corresponding set configured by the base station for the three SRS resource sets are {0, 1, 2, 3};{1, 2};{2, 2, 4, 4}, respectively. The base station transmits one DCI to the UE for triggering aperiodic SRS transmission. Suppose that this DCI triggers the transmission of SRS set 1 and SRS set 2, and the first indication information indicates sequence number 2, then the slot offset values ​​of SRS set 1 and SRS set 2 are 0 and 1, respectively. That is, the DCI indicates that there is an SRS set 1 transmission in the first available slot from the reference slot corresponding to SRS set 1, and there is an SRS set 2 transmission in the second available slot from the reference slot corresponding to SRS set 2.

[0253] At least one set of slot offset values ​​corresponding to different SRS resource sets can be configured separately, and among the set of slot offset values ​​configured for any two SRS resource sets, the number of slot offset values ​​may be the same or different. For example, in the above example, the base station configures the same number of slot offset values ​​for SRS set 1 and SRS set 3, or the number of slot offset values ​​configured for SRS set 2 is different from the number of slot offset values ​​configured for SRS set 1 and SRS set 3.

[0254] Optionally, the number of slot offset values ​​in at least one set of slot offsets corresponding to all SRS resource sets is the same.

[0255] For every aperiodic SRS resource set, the base station separately configures at least one set of slot offset values ​​corresponding to each aperiodic SRS resource set.

[0256] Alternatively, if the base station determines that there is an aperiodic SRS resource set with default slot values, it may not configure at least one set of slot offset values ​​corresponding to the aperiodic SRS resource set for the UE. The base station configures at least one set of slot offset values ​​corresponding to each aperiodic SRS resource set for some aperiodic SRS resource sets individually. For example, if the slot offset value corresponding to SRS set 1 is 0 by default, the base station configures at least one set of slot offset values ​​corresponding to SRS set 2 and SRS set 3, respectively, and does not configure at least one set of slot offset values ​​corresponding to SRS set 1.

[0257] At least one set of slot offset values ​​configured by the base station for the SRS resource set may be configured via RRC signaling, for example, in configuration information of the SRS resource set.

[0258] Alternatively, the slot offset value configured by the base station for each SRS resource set may be configured via MAC-CE signaling, such as direct configuration or indirect configuration.

[0259] Direct configuration involves configuring at least one set of slot offset values ​​configured in an SRS resource set via MAC-CE signaling.

[0260] In the indirect configuration method, the base station configures multiple slot offset values ​​for an SRS resource set, and indicates, for at least some of the SRS resource sets, the configuration of each SRS resource set in the some SRS resource sets and the corresponding multiple time unit offset values ​​to the UE through RRC signaling. At least one set of time unit offset values ​​among the multiple time unit offset values ​​corresponding to at least some of the SRS resource sets is indicated to the UE through MAC-CE signaling, so that some slot offset values ​​are activated. When a DCI triggers the SRS resource set, first indication information in the DCI indicates a sequence number of a slot offset value corresponding to a transmission slot of the SRS resource set among the at least one set of time unit offset values ​​configured for the SRS resource set by the base station through MAC-CE signaling. For example, assume that the base station configures three SRS resource sets, SRS set 1, SRS set 2, and SRS set 3, through RRC signaling, and the slot offset values ​​configured by the base station for the three SRS resource sets through RRC signaling are {0, 1, 2, 3}, {1, 2}, and {2, 2, 4, 4}, respectively. The base station indicates {1, 3} in {0, 1, 2, 3} to the UE through MAC-CE signaling as one set of slot offset values ​​corresponding to SRS set 1, and the base station indicates {2, 4} in {2, 2, 4, 4} to the UE through MAC-CE signaling as one set of slot offset values ​​corresponding to SRS set 3. Assume that the base station transmits one DCI to the UE for triggering aperiodic SRSS transmission. The DCI triggers transmission of SRS set 1 and SRS set 2. When the SRS transmission slot indication information in the DCI indicates sequence number 1, the slot offset value corresponding to SRS set 1 is the first slot offset value 1 activated by the MAC-CE, and the slot offset value corresponding to SRS set 2 is the first slot offset value 1 configured by RRC signaling.

[0261] The number of bits occupied by the sequence number in the DCI is a predefined fixed value, Alternatively, the number of bits occupied by the sequence number in the DCI is determined based on the number of time unit offset values ​​included in each of the at least one set of time unit offset values.

[0262] The number of bits occupied by the sequence number in the DCI is determined based on the maximum number of time unit offset values ​​included in each of the at least one set of time unit offset values. For example, a base station configures three SRS resource sets SRS set 1, SRS set 2, and SRS set 3 through RRC signaling, and the slot offset values ​​configured in these three SRS resource sets are {0, 1, 2, 3}, {1, 2}, and {2, 2, 4, 4}, respectively. Since the maximum number of slot offset values ​​corresponding to these three SRS resource sets is 4, the overhead of the transmission slot indication information of the DCI is

number

[0263] All aperiodic SRS resource sets configured by a base station for the UE may be all aperiodic SRS resource sets configured by a base station for the UE in one BWP / serving cell / frequency band.

[0264] The base station configures multiple slot offset values ​​in one SRS resource set in the following manner.

[0265] Scheme 1: The base station configures a maximum slot offset value M, or configures a minimum slot offset value m and a maximum slot offset value M, ranging from a set of slot offset values ​​indicated by DCI for the SRS resource set m to the value M. The value of the minimum slot offset value m may be the default slot 0 or 1, or other configured value. For example, taking a base station that configures three SRS resource sets SRS set 1, SRS set 2, and SRS set 3 for a UE through RRC signaling, the base station configures maximum slot offset values ​​for the three SRS resource sets, e.g., 1, 2, and 3, respectively. The slot offset values ​​corresponding to the three SRS resource sets are {0,1}, {0,1,2}, and {0,1,2,3}, respectively.

[0266] Alternatively, if the base station does not configure a maximum slot offset value for a particular SRS resource set, the slot offset value for this SRS resource set is zero.

[0267] Method 2: The base station configures multiple slot offset values ​​via the overhead of the first indication information in the DCI, or configures multiple slot offset values ​​via the overhead of the first indication information in the DCI and the configured minimum slot offset value.

[0268] Example 2 The base station transmits to the UE configuration information of SRS resource sets associated with aperiodic SRS resources, and for at least some of the SRS resource sets, the base station configures at least one set of slot offset values ​​for at least some of the corresponding trigger conditions, and optionally, for all of the SRS resource sets, the base station configures a respective set of slot offset values ​​for the corresponding trigger conditions of all the SRS resource sets.

[0269] A base station sends a DCI to a UE for triggering aperiodic SRS resource transmission, the DCI triggering the aperiodic SRS resource transmission via a specific trigger state in some aperiodic SRS resource sets, and the DCI includes first indication information for indicating an association relationship between the transmission slots of all SRS resource sets triggered by the DCI and a corresponding set of first slot offset values, the indication information indicating a sequence number, which indicates a sequence number of a slot offset value corresponding to an actual transmission slot of each SRS resource set triggered by the DCI among at least one set of slot offset values ​​configured by a base station in a trigger state indicated by the DCI.

[0270] Alternatively, for a particular SRS resource set, the base station does not configure a slot offset value for it in each trigger state, but configures at least one set of slot offset values, the set of slot offset values ​​being applicable to all trigger states, and the slot offset values ​​corresponding to actual transmission slots of the SRS resource set are the slot offset values ​​corresponding to sequence numbers indicated by DCI in the first set of slot offset values ​​configured by the base station. Alternatively, for a particular SRS resource set, the base station does not configure a slot offset value for the SRS resource set in each trigger state, and at this time, the slot offset values ​​corresponding to actual transmission slots of the SRS resource set are default values, e.g., 0. For SRS resource set 1 (set 1), it is assumed that at least one set of slot offset values ​​is configured as follows:

[0271] [Table 1]

[0272] For the SRS resource set (set 2), assume that at least one set of slot offset values ​​is configured as follows:

[0273] [Table 2]

[0274] The association between the trigger state indicated by the DCI, the indication value of the SRS transmission slot indication information in the DCI, and the slot offset value of each SRS resource set is as follows (the initial position is 0):

[0275] [Table 3]

[0276] At least one set of slot offset values ​​configured for different SRS resource sets in each trigger state may be configured separately, that is, the number of slot offset values ​​configured for any two SRS resource sets in each trigger state may be the same or different.

[0277] Optionally, the number of slot offset values ​​in at least one set of slot offsets corresponding to each trigger state of all SRS resource sets is the same.

[0278] For all aperiodic SRS resource sets, the base station separately configures at least one set of slot offset values ​​corresponding to each aperiodic SRS resource set in each trigger state.

[0279] If the base station does not configure at least one set of slot offset values ​​for a particular aperiodic SRS resource set in each trigger state, the corresponding slot offset value of the SRS resource set in each trigger state defaults to 0. For example, if the base station configures three aperiodic SRS resource sets, where the first SRS resource set does not configure a slot offset value in trigger state 1, the UE considers that the slot offset value corresponding to the SRS resource set in trigger state 1 is 0.

[0280] The slot offset value configured by the base station for each SRS resource configured in each trigger state may be configured via RRC signaling, for example, in the configuration information of the SRS resource set.

[0281] The slot offset value configured by the base station for each SRS resource configured in each trigger state may be configured via MAC-CE signaling, e.g., direct configuration or indirect configuration.

[0282] In the direct configuration, at least one set of slot offset values ​​is configured in each trigger state for the SRS resource set by MAC-CE signaling.

[0283] Indirect configuration includes the following: the base station configures multiple slot offset values ​​for an SRS resource set in each trigger state, and for at least some of the SRS resource sets, indicates to the UE via RRC signaling the configuration of each SRS resource set and the corresponding multiple time unit offset values ​​in the some SRS resource sets, and indicates to the UE via MAC-CE signaling at least one set of time unit offset values ​​corresponding to at least some of the SRS resource sets in each trigger state, whereby some slot offset values ​​are activated. When the DCI triggers the SRS resource set, the first indication information in the DCI indicates, via MAC-CE signaling, a sequence number of a slot offset value corresponding to a transmission slot of the SRS resource set among the at least one set of time unit offset values ​​configured by the base station in each trigger state.

[0284] For example, the base station configures three SRS resource sets, SRS set 1, SRS set 2, and SRS set 3, via RRC signaling. Assume that the slot offset values ​​configured by the base station for the three SRS resource sets via RRC signaling are {0, 1, 2, 3}, {1, 2}, and {2, 2, 4, 4}, respectively. The base station indicates {1, 3} in {0, 1, 2, 3} to the UE via MAC-CE as a set of slot offset values ​​corresponding to SRS set 1 in trigger state 1, and the base station indicates {2, 4} in {2, 2, 4, 4} to the UE via MAC-CE as a set of slot offset values ​​corresponding to SRS set 3 in trigger state 1. Assume that the base station transmits one DCI to the UE for triggering aperiodic SRSS transmission. When the DCI triggers transmission of SRS set 1 and SRS set 2 via trigger state 1, and the SRS transmission slot indication information in the DCI indicates sequence number 1, the slot offset value corresponding to SRS set 1 is the first slot offset value 1 activated by the MAC-CE for SRS set 1 in trigger state 1, and the slot offset value corresponding to SRS set 2 is the first slot offset value 1 configured for SRS set 2 in trigger state 1 via RRC signaling.

[0285] The number of bits occupied by the sequence number in the DCI is a predefined fixed value, Alternatively, the number of bits occupied by the sequence number in the DCI is determined based on the number of slot offset values ​​configured by the base station for the UE for all aperiodic SRS resource sets in each trigger state.

[0286] The number of bits occupied by the sequence number in the DCI is determined based on the maximum number of slot offset values ​​configured by the base station for the UE for all aperiodic SRS resource sets in each trigger state (all aperiodic SRS resource sets configured by the base station for the UE may be all aperiodic SRS resource sets configured by the base station for the UE in one BWP / serving cell / frequency band).

[0287] Optionally, assuming that the maximum value is N, the overhead of the first indication information in the DCI is

number

number

[0288] Optionally, the base station configures at least one set of slot offset values ​​corresponding to each trigger condition for the SRS resource set in the following manner.

[0289] Manner 1: The base station configures a maximum slot offset value for an SRS resource set for each trigger state separately, and a set of slot offset values ​​indicated by DCI for the SRS resource set ranges from m to the numerical value M. The value of the minimum slot offset value m is 0 or 1 by default. For example, taking a base station configuring three SRS resource sets SRS set 1, SRS set 2, and SRS set 3 for a UE through RRC signaling, the base station configures maximum slot offset values ​​for the three SRS resource sets in trigger state 1, for example, 1, 2, and 3, respectively. The slot offset values ​​corresponding to the three SRS resource sets in trigger state 1 are {0,1}, {0,1,2}, and {0,1,3}, respectively. Optionally, if the base station does not configure a maximum slot offset value for a trigger state of a specific SRS resource set, the slot offset value of the SRS resource configured for this trigger state is a default value (for example, 0).

[0290] Method 2: The base station configures multiple slot offset values ​​through the overhead of the first indication information in the DCI, or configures multiple slot offset values ​​through the overhead of the first indication information in the DCI and the configured minimum slot offset value.

[0291] After describing the method for indicating an RS transmission position applied to a network side device, a method for determining an RS transmission position applied to a UE will be described in detail below.

[0292] The embodiment of the present invention provides a method for determining an RS transmission position applied to a UE, as shown in Figure 3. The method includes the following steps:

[0293] Step S301: According to an instruction from the network side, determine at least one set of time unit offset values ​​corresponding to each configured RS resource.

[0294] The RS resource may be an aperiodic RS resource, a semi-persistent RS resource, or a periodic RS resource. The types of RS resources include, but are not limited to, SRS resources, CSI-RS resources, CSI-IM resources, etc. Taking the aperiodic RS resource as an example, the aperiodic RS resource may include, but is not limited to, an uplink aperiodic RS resource or a downlink aperiodic RS resource, and the uplink aperiodic RS resource may include, but is not limited to, an aperiodic SRS resource. The downlink aperiodic RS may include, but is not limited to, an aperiodic CSI-RS resource, an aperiodic CSI-IM resource. The RS resource according to the embodiment of the present invention may be any of the above-mentioned resources.

[0295] Step S302: Receive a DCI sent from a network side, and determine at least one RS resource in the RS resources according to the DCI.

[0296] Step S303: Determine a first time unit offset value corresponding to the at least one RS resource according to the first indication information in the DCI.

[0297] Step S304: Determine a transmission position of the at least one RS resource according to a first time unit offset value corresponding to the at least one RS resource.

[0298] An association relationship between a first time unit offset value corresponding to each RS resource in the at least one RS resource and a set of first time unit offset values ​​corresponding to each RS resource is indicated by the same first indication information, wherein the first time unit offset value is a time unit offset value corresponding to a transmission position of each RS resource, and the set of first time unit offset values ​​is one of the at least one set of time unit offset values.

[0299] For RS resources that are triggered by the DCI of the present invention and require transmission position indication, the first indication information indicates the association relationship between the first time unit offset value corresponding to the RS resource and the set of first time unit offset values ​​corresponding to each RS resource, so that the transmission position of the RS resource can be indicated with less DCI signaling, and the flexibility of the triggering and transmission of the RS resource is improved.

[0300] The first indication information is in a designated information field of the DCI. Different values ​​of the designated information field can be used to represent different first indication information.

[0301] In an embodiment of the present invention, a certain state of the specification information field of the DCI indicates that the first slot time unit value indicates an offset value of a slot unit in the first set of time unit offset values, and the DCI indicates an association relationship between the first slot time unit value and the first set of time unit offset values.

[0302] If the time unit is a slot, the time unit offset can be expressed as a slot offset.

[0303] Optionally, the specific information field is at least one of the following: That is, the UE determines the first time unit offset value corresponding to the at least one RS resource based on at least one of the following specific information fields: (1) A slot offset information field indicating the slot offset value of the RS resource triggered by the DCI.

[0304] (2) MCS indication field: A part of the state of the MCS indication field indicates the modulation and coding scheme of the data scheduled by the DCI, and a part of the state indicates the time unit offset value.

[0305] (3) An SRS request field, which triggers the at least one RS resource to be sent simultaneously and indicates the RS slot offset value.

[0306] When the specification information field of the DCI includes a slot offset information field and an MCS indication field indicating a slot offset value of the RS resource triggered by the DCI, the time domain position of the RS resource and the associated relationship are determined based on the MCS indication field, the slot offset information field and the specified information.

[0307] Determining at least one RS resource in the RS resources according to the DCI specifically includes: The at least one RS resource is determined by a trigger signaling in the DCI.

[0308] The at least one RS resource is an RS resource triggered by trigger signaling of the DCI.

[0309] Alternatively, the UE may determine the transmission time unit of the RS resource as follows:

[0310] The time unit for transmitting one RS resource is the (t+1)th available time unit from the reference time unit, where t is the first time unit offset value.

[0311] Alternatively, the reference time unit is the time unit in which the DCI is located.

[0312] Alternatively, the reference time unit is a time unit offset by k time units from the time unit in which the DCI is located, where k is determined based on information indicated by a network side device.

[0313] Optionally, the DCI triggers RS resources by triggering an RS resource set, i.e., the DCI triggers one or more RS resource sets, at which point the RS resources associated with the triggered RS resource set are triggered.

[0314] Optionally, the first time unit offset value of an RS resource is determined by the first time unit offset value of an RS resource set associated with the RS resource, and the UE determines the time unit for transmitting the RS resource set according to the first time unit offset value of the RS resource set. The time unit for transmitting the RS resource set is the time unit for transmitting the RS resource. That is, the first indication information in the DCI indicates the first time unit offset value corresponding to the at least one RS resource, and the first time unit offset value corresponding to the at least one RS resource includes the first indication information in the DCI indicating the first time unit offset value of the at least one RS resource set.

[0315] Optionally, the UE determines a time unit for transmitting one RS resource set as follows: The time unit for transmitting one RS resource set is the (t+1)th available time unit from the reference time unit, where t is a first time unit offset value. Optionally, the reference time unit is the time unit in which the DCI is located. Optionally, the reference slot is a time unit offset by k time units from the time unit in which the DCI is located, where the time unit k is determined based on information indicated by an instruction from the network side device.

[0316] Optionally, the at least one RS resource includes a plurality of RS resources.

[0317] The association relationship between the first time unit offset value corresponding to each RS resource in the at least one RS resource and the set of first time unit offset values ​​corresponding to each RS resource is the same.

[0318] The first indication information indicates one association relationship.

[0319] Optionally, the time unit is a slot or a sub-slot or a symbol.

[0320] Optionally, the association relationship between the first time unit offset value and the set of first time unit offset values ​​includes at least one of the following: (1) The first time unit offset value is a time unit offset value at a first position in a first set of time unit offset values, the first position being a position indicated by the first indication information.

[0321] A first time unit offset value at a first position in the set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information. If the first indication information indicates an associated relationship, the first time unit offset value at the same position in the set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information.

[0322] Optionally, the first time unit offset value is a time unit offset value at a first position in the set of first time unit offset values ​​and includes at least one of the following: (i) The first time unit offset value is a time unit offset value whose sequence in the set of first time unit offset values ​​is a first sequence, the first sequence being a sequence indicated by the first indication information.

[0323] Assuming that the time unit is a slot, the network side device configures a set of slot offset values ​​for three RS resources, and the sets of slot offset values ​​are {0,1,2,3}, {1,2}, and {2,3,4,5}, respectively. These three RS resources are triggered by DCI. If the first indication information included in the DCI indicates that the sequence number is 2, the UE determines that the slot offset values ​​corresponding to the three RS resources are 1, 2, and 3, respectively.

[0324] (ii) a first time unit offset value is a time unit offset value corresponding to a first sequence number in a first set of time unit offset values, the first sequence number being a sequence number indicated by the first indication information;

[0325] For the same sequence number, if different time unit offset values ​​are configured by the network side for each RS resource, the UE can transmit different RS resources at different time unit offset positions. The sequence number may be a function of the sequence n=mk, where n is the sequence, m is the sequence number, and k is a natural number less than m (the position of the initial time unit offset value is 1), or k is a natural number less than m (the position of the initial time unit offset value is 0). Assume that the time unit is a slot, and the position of the initial slot offset value is 1. The set of slot offset values ​​is the sequence n=m-1, and a set of slot offset values ​​configured for three RS resources according to the instruction of the network side device is determined to be {0, 1, 2, 3}, {1, 2}, {2, 3, 4, 5}, respectively. These three RS resources are triggered by DCI. The UE indicates that the sequence number is 2 based on the first instruction information included in the DCI, and determines that the slot offset values ​​corresponding to the three RS resources are 0, 1, and 2, respectively.

[0326] (2) The first time unit offset value is a time unit offset value associated with a first trigger state in the first set of time unit offset values, the first trigger state being a trigger state indicated by the first indication information.

[0327] Optionally, the first time unit offset value is predetermined as a time unit offset value associated with a first trigger condition in a first set of time unit offset values. The first indication is indicative of the first trigger condition.

[0328] When the first indication information indicates one association relationship, the first time unit offset value of the first trigger state in the set of first time unit offset values ​​corresponding to each RS resource can be determined by the first indication information. Assuming that the time unit is a slot, the network side device configures a set of slot offset values ​​{2, 5, 4} for RS resource 1. Here, trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. When the UE determines that the trigger state is 2 based on the first indication information in the DCI, it determines that the slot offset value indicated by the network side is 5.

[0329] (3) The first time unit offset value is a time unit offset value whose identifier in the set of first time unit offset values ​​is a first identifier, and the first identifier is an identifier indicated by the first indication information.

[0330] If the first indication information indicates an association relationship, determine a first time unit offset value of a first trigger state in a set of first time unit offset values ​​corresponding to each RS resource according to the first indication information. Assuming that the time unit is a slot, a set of slot offset values ​​configured by the network side device for one RS resource is {0, 1, 2, 3}. The corresponding identifiers are {2, 1, 3, 0}. The UE triggers the RS resource according to the DCI, and determines that the slot offset value corresponding to the RS resource is 3 when the identifier indicated by the first indication information included in the DCI is 0.

[0331] Optionally, the UE determines a first time unit offset value corresponding to each RS resource in the at least one RS resource based on an association relationship between a first time unit offset value corresponding to each RS resource in the at least one RS resource indicated by the first indication information and a set of first time unit offset values ​​corresponding to each RS resource.

[0332] The association relationship indicated by the first instruction information may be a combination of the aforementioned association relationships. Specifically, the second type of association relationship may be combined with any other association relationship. For example, when the second type of association relationship is combined with the first type of association relationship, the first instruction information may determine a first time unit offset value at a first position in a first trigger state in a set of first time unit offset values ​​corresponding to each RS resource. Assuming that the time unit is a slot, the slot offset values ​​configured by the network side device for the RS resource are {0, 1, 2, 3} corresponding to trigger state 1, {1, 2} corresponding to trigger state 2, and {2, 3, 4, 5} corresponding to trigger state 3. When the UE triggers the RS resource in trigger state 2 according to the DCI, the first instruction information included in the DCI indicates a slot offset value whose sequence in trigger state 2 is 2, and determines that the slot offset value corresponding to the RS resource is 2.

[0333] Optionally, the UE determines the first time unit offset value based on at least one of a first location / a first trigger state / a first identifier indicated by the DCI.

[0334] The first indication indicates that an association relationship between the first time unit offset value and the set of first time unit offset values ​​includes at least one of the following: The first instruction indicates that the first time unit offset value is a time unit offset value at a first position in a first set of time unit offset values, or a pre-agreed that the first time unit offset value is a time unit offset value at a first position indicated by the first instruction in a first set of time unit offset values. The first instruction indicates the first position.

[0335] The first instruction indicates that the first time unit offset value is a time unit offset value associated with a first trigger condition in a first set of time unit offset values, or a pre-agreed that the first time unit offset value is a time unit offset value associated with a first trigger condition indicated by the first instruction in a first set of time unit offset values. The first instruction indicates the first trigger condition.

[0336] The first indication information indicates that the first time unit offset value is a time unit offset value whose identifier in the first set of time unit offset values ​​is a first identifier, or it is pre-agreed that the first time unit offset value is a time unit offset value of a first identifier indicated by the first indication information in the first set of time unit offset values. The first indication information indicates the first identifier.

[0337] The pre-agreed manner may be pre-agreed upon by a protocol. And, the UE may also receive one second indication information transmitted from a network side device, where the second indication information indicates that a first time unit offset value is a time unit offset value of the first position / first trigger state / first identifier indicated by the first indication information in a set of first time unit offset values.

[0338] Alternatively, the determination may be performed before "determining a first time unit offset value corresponding to the at least one RS resource according to first indication information in the DCI transmitted from a network side device."

[0339] Optionally, the first instruction indicates that the first time unit offset value is a time unit offset value at a first position in the first set of time unit offset values, or it is pre-agreed that the first time unit offset value is a time unit offset value at a first position indicated by the first instruction in the first set of time unit offset values. The first instruction indicates the first position by any of the following:

[0340] The first instruction information indicates that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence, and the information indicates that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence or that the first time unit offset value is a time unit offset value whose sequence in the first set of time unit offset values ​​is a first sequence indicated by the first instruction information, and the first instruction information indicates the first sequence.

[0341] The first indication information indicates that the first time unit offset value is a time unit offset value corresponding to a first sequence number in a first set of time unit offset values, or pre-agreed that the first time unit offset value is a time unit offset value corresponding to a first sequence number indicated by the first indication information in a first set of time unit offset values, the first indication information indicating the first sequence number.

[0342] According to the configuration information transmitted by the network side device, the UE determines at least one set of time unit offset values ​​corresponding to the RS resources indicated by the network side device. The network side device indicates to the UE at least one set of time unit offset values ​​corresponding to the RS resources, which is also referred to as configuring for the UE at least one set of time unit offset values ​​corresponding to the RS resources. Therefore, the UE determines at least one set of time unit offset values ​​corresponding to the RS resources according to the instruction of the network side. When there are multiple RS resources, the corresponding determination manner is as follows:

[0343] Determination method 1: For at least one of the RS resources, determine at least one set of time unit offset values ​​corresponding to each RS resource configured by the network side device.

[0344] The UE determines a time unit offset value configured by the network side according to a single RS resource, for example, a set of slot offset values ​​{0, 1, 2, 3} configured by the network side device for RS resource 1, a set of slot offset values ​​{1, 2} configured by the network side device for RS resource 2, and a set of slot offset values ​​{2, 3, 4, 5} configured by the network side device for RS resource 3.

[0345] Determination method 2: For at least one first RS resource in the RS resources, determine at least one corresponding set of time unit offset values ​​configured by a network side device for a first RS resource set associated with each first RS resource, where the first RS resource is an associated RS resource set, the associated RS resource set is an RS resource configured with at least one set of time unit offset values, and the first RS resource set is an RS resource set associated with at least one of the first RS resources and configured with at least one set of time unit offset values.

[0346] Optionally, determining at least one set of time unit offset values ​​corresponding to RS resources according to an instruction from the network side specifically includes: According to an instruction from the network side, determine at least one set of time unit offset values ​​corresponding to a first RS resource set associated with a first RS resource among the RS resources. For example, the UE determines that RS resource 1, RS resource 2, and RS resource 3 are configured in the RS resource list of RS resource set 1. The UE determines that RS resource 4 and RS resource 5 are configured in the RS resource list of RS resource set 2. The UE determines a set of slot offset values ​​{0, 1, 2, 3} corresponding to the RS resource set set1. The UE determines a set of slot offset values ​​{1, 2} corresponding to the RS resource set set 2.

[0347] Optionally, when determining, according to an instruction from the network side, at least one set of time unit offset values ​​corresponding to a first RS resource set associated with a first RS resource among the RS resources, the first time unit offset value corresponding to the first RS resource is a second time unit offset value corresponding to the first RS resource set associated with the first RS resource, and the set of first time unit offset values ​​corresponding to the first RS resource is a set of second time unit offset values ​​corresponding to the first RS resource set associated with the first RS resource.

[0348] The first indication information indicates an association relationship between second time unit offset values ​​corresponding to at least a portion of first RS resource sets associated with each first RS resource in the at least one first RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set.

[0349] Optionally, at least a portion of the first RS resource sets associated with one first RS resource are first RS resource sets associated with the first RS resource and triggered by the DCI.

[0350] In the above-mentioned embodiment, the first instruction information indicates an association relationship between a second time unit offset value corresponding to at least a portion of first RS resource sets associated with each first RS resource in the at least one first RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set, thereby indicating an association relationship between a first time unit offset value of each first RS resource in the at least one first RS resource and a set of first time unit offset values ​​corresponding to the first RS resource.

[0351] Taking the above configuration as an example, in which a set of slot offset values ​​{0, 1, 2, 3} is configured for set 1 and a set of slot offset values ​​{1, 2} is configured for set 2, when RS resource 4 and RS resource 4 are triggered via DCI and a slot offset value 2 is indicated, the first indication information indicates an association relationship between the slot offset value 2 of set 2 and {1, 2}.

[0352] Optionally, in the method according to this embodiment, The first RS resource in the at least one RS resource includes a plurality of first RS resources; an association relationship between each first RS resource set associated with a first RS resource in the at least one RS resource and a set of second time unit offset values ​​corresponding to each first RS resource set is the same; The first indication information indicates one association relationship.

[0353] For each first RS resource set associated with a first RS resource among the at least one RS resource, one first indication information indicates an association relationship between a second time unit offset value corresponding to each first RS resource set and a set of second time unit offset values ​​corresponding to each first RS resource set.

[0354] Optionally, the association relationship between the second time unit offset value and the set of second time unit offset values ​​includes at least one of the following: (1) The second time unit offset value is a time unit offset value at a first position in the set of second time unit offset values, the first position being a position indicated by the first indication information.

[0355] The first indication information can determine a second time unit offset value at a first position in a set of second time unit offset values ​​corresponding to each first RS resource set associated with the first RS resource. If the first indication information indicates an associated relationship, the first indication information can determine a second time unit offset value at the same position in the set of second time unit offset values ​​corresponding to each first RS resource set associated with the first RS resource.

[0356] Optionally, the second time unit offset value is a time unit offset value at a first position in the set of second time unit offset values ​​and includes at least one of the following: (i) The second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence, the first sequence being a sequence indicated by the first indication information.

[0357] Assuming that the time unit is a slot, the UE determines according to the instruction from the network side that the set of slot offset values ​​corresponding to the three RS resource sets are {0, 1, 2, 3}, {1, 2}, {2, 3, 4, 5}: {0, 1, 2, 3};{1, 2};{2, 3, 4, 5}. When the UE triggers the RS resources of the three RS resource sets by the DCI, the UE determines according to the first instruction information pointer included in the DCI that the sequence is 2, and the slot offset values ​​corresponding to the RS resources of the three RS resource sets are 1, 2, and 3, respectively.

[0358] (ii) the second time unit offset value is a time unit offset value corresponding to a first sequence number in the set of second time unit offset values, the first sequence number being a sequence number indicated by the first indication information;

[0359] For the same sequence number, the time unit offset value configured by the network side for each RS resource set is different. The UE can transmit the RS resource set at different time unit offset positions. The sequence number may be a function of the sequence n=mk, where n is the sequence, m is the sequence number, and k is a natural number less than m (the position of the initial time unit offset value is set to 1), or k is a natural number less than m (the position of the initial time unit offset value is set to 0). Assume that the time unit is a slot, and the position of the initial slot offset value is set to 1. The set of slot offset values ​​is the sequence n=m-1, and the UE determines that a set of slot offset values ​​corresponding to each of the three RS resource sets indicated by the network side device are {0, 1, 2, 3}, {1, 2}, {2, 3, 4, 5}. The UE triggers the three RS resource sets by DCI, and determines that the slot offset values ​​corresponding to the three RS resource sets are 0, 1, and 2, respectively, according to the first indication information included in the DCI, when the sequence number indicates 2.

[0360] (2) The second time unit offset value is a time unit offset value associated with a first trigger state in the set of second time unit offset values, the first trigger state being a trigger state indicated by the first instruction information.

[0361] When the first indication information indicates an association relationship, the first indication information can determine a second time unit offset value of the first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set. Assuming that the time unit is a slot, the UE determines a set of slot offset values ​​corresponding to RS resource set 1 as {2, 5, 4} according to the indication of the network side device, where trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. If the UE indicates trigger state 2 according to the first indication information, it determines that the indicated slot offset value is 5.

[0362] (3) The second time unit offset value is a time unit offset value whose identifier in the set of second time unit offset values ​​is a first identifier, and the first identifier is an identifier indicated by the first indication information.

[0363] When the first indication information indicates an association relationship, the first indication information can determine a second time unit offset value of the first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set. Assuming that the time unit is a slot, the UE determines that a set of slot offset values ​​corresponding to an RS resource set configured by the network side device are {0, 1, 2, 3}, and the corresponding identifiers are {2, 1, 3, 0}. When the UE triggers the RS resource of the RS resource set by DCI, the UE determines that the slot offset value corresponding to the RS of the RS resource set is 3 based on the identifier 0 indicated by the first indication information included in the DCI.

[0364] Regarding the above-mentioned association relationship and determination manner, optionally, the association relationship between the first indication information indicating the second time unit offset value and the set of second time unit offset values ​​includes at least one of the following: (1) The first instruction information indicates that the second time unit offset value is a time unit offset value at a first position in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value at a first position indicated by the first instruction information within a second set of time unit offset values, and the first instruction information indicates the first position.

[0365] (2) The first instruction information indicates that the second time unit offset value is a time unit offset value associated with a first trigger condition in a second set of time unit offset values, or it is agreed in advance that the second time unit offset value is a time unit offset value associated with a first trigger condition indicated by the first instruction information in the second set of time unit offset values, and the first instruction information indicates the first trigger condition.

[0366] (3) The first instruction information indicates that the second time unit offset value is a time unit offset value whose identifier in the set of second time unit offset values ​​is a first identifier, or it is pre-agreed that the second time unit offset value is a time unit offset value corresponding to the first identifier indicated by the first instruction information in the set of second time unit offset values, and the first instruction information indicates the first identifier.

[0367] The pre-agreed scheme is pre-agreed upon according to a protocol, and the UE receives a piece of third indication information transmitted from a network side device, and the third indication information indicates that a second time unit offset value is a time unit offset value within a set of second time unit offset values ​​corresponding to the first position / first trigger state / first identifier indicated by the first indication information.

[0368] If the UE receives third instruction information transmitted from a network side device, the step of receiving the third instruction information may be before step S302: "Receive DCI transmitted from the network side, and determine at least one RS resource within the RS resources according to the DCI."

[0369] Optionally, the third instruction information is the same instruction information as the second instruction information.

[0370] Optionally, the first instruction indicates that the second time unit offset value is a time unit offset value at a first position in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value at a first position indicated by the first instruction within a second set of time unit offset values. The first instruction indicates the first position by any of the following:

[0371] (1) The first instruction information indicates that the second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence, or it is pre-agreed that the second time unit offset value is a time unit offset value whose sequence in the set of second time unit offset values ​​is a first sequence indicated by the first instruction information, and the first instruction information indicates the first sequence.

[0372] (2) The first indication information indicates that the second time unit offset value is a time unit offset value corresponding to a first sequence number in a second set of time unit offset values, or it is pre-agreed that the second time unit offset value is a time unit offset value corresponding to a first sequence number indicated by the first indication information in a second set of time unit offset values, and the first indication information indicates the first sequence number.

[0373] The association relationship indicated by the first instruction information may be a combination of the association relationships described above. Specifically, the second type of association relationship may be combined with any other association relationship. For example, when the second type of association relationship is combined with the first type of association relationship, the first instruction information can determine a second time unit offset value at a first position in a first trigger state in a set of second time unit offset values ​​corresponding to each first RS resource set of the UE. Assuming that the time unit is a slot, the UE determines, according to the instruction of the network side device, that the slot offset values ​​corresponding to the RS resource set are {0, 1, 2, 3} corresponding to trigger state 1, {1, 2} corresponding to trigger state 2, and {2, 3, 4, 5} corresponding to trigger state 3. When the UE triggers the RS resource of the RS set in state 2 by the DCI, the UE determines, according to the first instruction information included in the DCI, that the slot offset value whose sequence is 2 in trigger state 2 is indicated, and the slot offset value corresponding to the RS resource in the RS resource set is 2.

[0374] When the UE determines, through a network side device, at least one set of time unit offset values ​​corresponding to RS resources, all the RS resources are determined by the above-mentioned determination method 1, or all the RS resources are determined by the above-mentioned determination method 2, or some of the RS resources are determined by the above-mentioned determination method 1, and some of the RS resources are determined by the above-mentioned determination method 2.

[0375] Optionally, determining at least one set of time unit offset values ​​corresponding to RS resources according to an instruction from the network side specifically includes: For at least some of the RS resources, determine at least one set of time unit offset values ​​corresponding to the RS resources according to at least one set of time unit offset values ​​corresponding to each RS resource individually configured by the network side, where the number of configured time unit offset values ​​can be the same or different, and the at least one set of time unit offset values ​​corresponding to each configured RS resource can include at least one set of time unit offset values ​​applicable to all trigger conditions, and at least one set of time unit offset values ​​corresponding to each of at least some trigger conditions.

[0376] Optionally, determining at least one set of time unit offset values ​​corresponding to RS resources according to an instruction from the network side specifically includes: For at least one RS resource among at least some of the RS resources, determine at least one set of time unit offset values ​​corresponding to the RS resource according to at least one set of time unit offset values ​​corresponding to at least some trigger states of each RS resource individually configured by the network side.

[0377] In this scheme, an association between the trigger state of an RS resource and the RS time-domain transmission position is established, which allows more combinations of RS resource time-domain transmission positions to be indicated via DCI for the same DCI overhead as in the previous method.

[0378] As an optional embodiment, for at least one RS resource among at least some of the RS resources, at least one set of time unit offset values ​​corresponding to each of all trigger conditions is configured individually by the network side for each RS resource.

[0379] When a set of time unit offset values ​​corresponding to each of at least some of the trigger states of the RS resource is determined according to an instruction from the network side, a set of time unit offset values ​​corresponding to each of at least some of the trigger states configured by the network side for each of the RS resources can be determined. Optionally, a set of time unit offset values ​​corresponding to each of the trigger states of the part of the trigger states configured for each of the RS resources can be determined according to an instruction from the network side. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5} is configured for RS resource 1. Here, trigger state 1 corresponds to slot offset value 2, and trigger state 2 corresponds to slot offset value 5. Optionally, a set of time unit offset values ​​corresponding to each of all the trigger states configured for each of the RS resources is determined according to an instruction from the network side. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for RS resource 1. Here, trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4. For example, RS resource 1 has three trigger states, and one slot offset value is configured for each trigger state for RS resource 1, which are 1, 2, and 3. In this case, a set of slot offset values ​​corresponding to each trigger state configured for RS resource 1 is {1, 2, 3}.

[0380] Optionally, a set of time unit offset values ​​corresponding to each of at least some of the trigger states is determined according to an instruction from the network side. Optionally, a set of time unit offset values ​​corresponding to each of the trigger states among the at least some of the states configured in the RS resource is determined. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource 1, and a set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource 1. Optionally, a set of time unit offset values ​​corresponding to each of all of the trigger states can also be configured for the RS resource. For example, RS resource 1 has three trigger states, and a set of slot offset values ​​{2, 5, 4} is configured for trigger state 1 of RS resource 1, a set of slot offset values ​​{0, 1, 2} is configured for trigger state 2 of RS resource 1, and a set of slot offset values ​​{0, 3, 4} is configured for trigger state 3 of RS resource 1.

[0381] The first set of time unit offset values ​​corresponding to the at least one RS resource includes at least one of the following: (1) A set of time unit offset values ​​corresponding to each trigger condition configured on the second RS resource.

[0382] (2) A set of time unit offsets consisting of all time unit offset values ​​corresponding to the first trigger condition configured on the second RS resource.

[0383] Here, the first trigger state is a trigger state corresponding to the case where the DCI triggers the first RS resource.

[0384] When the network side device configures a time unit offset value for at least one RS resource in configuration method 2, the RS resource for which the time unit offset value is configured includes at least one first RS resource, and configures at least one set of corresponding time unit offset values ​​configured by the network side for a first RS resource set associated with each first RS resource according to an instruction from the UE network side, where the at least one set of time unit offset values ​​includes at least one set of time unit offset values ​​applicable to all trigger states, and may include at least one set of time unit offset values ​​corresponding to each of at least some of the trigger states.

[0385] Optionally, the RS resource includes a plurality of first RS resources, and determining at least one set of time unit offset values ​​corresponding to the RS resources according to an instruction from a network side specifically includes: For a first RS resource set associated with at least a portion of the plurality of first RS resources, at least one set of time unit offset values ​​corresponding to the RS resources are determined according to at least one set of time unit offset values ​​corresponding to each first RS resource set individually configured by the network side.

[0386] In an alternative embodiment, the first RS resource set associated with at least some of the first RS resources includes a plurality of second RS resource sets, and the second RS resource set is configured with at least one set of time unit offsets corresponding to at least some associated trigger conditions of the first RS resource set, and the at least some associated trigger conditions include the first RS resource set of the trigger condition indicated by the DCI. For example, the triggered first RS resources include RS resource 1, RS resource 2, RS resource 3, RS resource 4, RS resource 5, RS resource 6, and RS resource 7, where RS resource 1, RS resource 2, and RS resource 3 are associated with RS resource set 1, RS resource 4 and RS resource 5 are associated with RS resource set 2, and RS resource 5, RS resource 6, and RS resource 7 are associated with RS resource set 3. The UE determines time unit offset values ​​applicable to all the corresponding set of trigger conditions configured for RS resource set 1 according to the instruction from the network side. Determine two corresponding sets of time unit offset values ​​configured for RS resource set 2, respectively: a set of time unit offset values ​​corresponding to trigger state 1 and a set of time unit offset values ​​corresponding to trigger state 2. Determine time unit offset values ​​applicable to all trigger states in the set configured for RS resource set 1. Determine three sets of time unit offset values ​​configured for RS resource set 3, including time unit offset values ​​applicable to all trigger states in the set, a set of time unit offset values ​​corresponding to trigger state 1, and a set of time unit offset values ​​corresponding to trigger state 2.

[0387] As an optional embodiment, optionally, the first RS resource set associated with at least a portion of the plurality of first RS resources includes a plurality of second RS resource sets, and determining at least one set of time unit offset values ​​corresponding to the RS resources according to an instruction from a network side specifically includes: For at least some of the plurality of second RS resource sets, at least one set of time unit offset values ​​corresponding to the RS resources are determined according to at least one set of time unit offset values ​​corresponding to at least some of the trigger states corresponding to each second RS resource set individually configured by the network side.

[0388] Optionally, when determining a set of time unit offset values ​​corresponding to at least some of the trigger states corresponding to each of the configured second RS resource sets, configure a set of time unit offset values ​​corresponding to each of the trigger states for the second RS resource set, and optionally configure a set of time unit offset values ​​corresponding to each of the trigger states among the some of the trigger states for each of the second RS resource sets. For example, RS resource set 1 has three trigger states, and configure a set of slot offset values ​​{2, 5} for RS resource set 1, where trigger state 1 corresponds to slot offset value 2, and trigger state 2 corresponds to slot offset value 5. Optionally, configure a set of time unit offset values ​​corresponding to each of the trigger states among all the trigger states for each of the configured second RS resource sets. For example, RS resource set 1 has three trigger states, and configures a set of slot offset values ​​{2, 5, 4} for RS resource set 1, where trigger state 1 corresponds to slot offset value 2, trigger state 2 corresponds to slot offset value 5, and trigger state 3 corresponds to slot offset value 4.

[0389] When determining at least one set of time unit offset values ​​corresponding to at least some of the trigger states corresponding to each of the second RS resource sets individually configured on the network side, selectively, configure one set of time unit offset values ​​corresponding to each of the trigger states among the some states for each of the second RS resource sets. For example, RS resource set 1 has three trigger states, and configure one set of slot offset values ​​{2, 5, 4} for trigger state 1 of RS resource set 1, and configure one set of slot offset values ​​{0, 1, 2} for trigger state 2 of RS resource set 1. Optionally, one set of time unit offset values ​​corresponding to each of the trigger states among all the trigger states for each of the second RS resource sets may be configured. For example, RS resource set 1 has three trigger states, and configure one set of slot offset values ​​{2, 5, 4} for trigger state 1 of RS resource set 1, and configure one set of slot offset values ​​{0, 1, 2} for trigger state 2 of RS resource set 1. Configure one set of slot offset values ​​{0, 3, 4} for trigger state 3 of RS resource set 1.

[0390] Optionally, the second set of time unit offset values ​​corresponding to at least one of the first RS resource sets includes at least one of the following: A set of time unit offset values ​​corresponding to each respective trigger condition configured in the first RS resource set.

[0391] A set of time unit offset values ​​consisting of all time unit offset values ​​corresponding to a first trigger condition configured in the first RS resource set.

[0392] Here, the first trigger state is a trigger state corresponding to when the DCI triggers the first RS resource set.

[0393] Optionally, the second set of time unit offset values ​​corresponding to at least one second RS resource set is at least one set of time unit offset values ​​corresponding to a trigger condition indicated by the DCI.

[0394] Optionally, determining at least one set of time unit offset values ​​corresponding to RS resources according to an instruction from the network side specifically includes: Manner 1: Determine the configuration of RS resources and at least one corresponding set of time unit offset values ​​according to the RRC signaling sent from the network side.

[0395] Selectively, determine a configuration of an indicated RS resource and at least one set of corresponding time unit offset values ​​according to the RRC signaling sent from the network side, specifically, determine a configuration of an indicated RS resource, a configuration of an RS resource set associated with the RS resource, and at least one set of time unit offset values ​​corresponding to the RS resource set associated with the RS resource according to the RRC signaling sent from the network side.

[0396] Manner 2: Determine the configuration of RS resources and at least one corresponding set of time unit offset values ​​according to the MAC-CE signaling sent from the network side.

[0397] Optionally, determining the configuration of RS resources and at least one corresponding set of time unit offset values ​​according to the MAC-CE signaling sent from the network side specifically includes: The network side determines, via MAC-CE signaling, a configuration of an indicated RS resource, a configuration of an RS resource set associated with the RS resource, and at least one set of time unit offset values ​​corresponding to the RS resource set associated with the RS resource.

[0398] Method 3: Determine a configuration of RS resources and corresponding multiple time unit offset values ​​according to RRC signaling sent from the network side, and determine at least one set of time unit offset values ​​among the multiple time unit offset values ​​corresponding to at least some of the RS resources according to MAC-CE signaling sent from the network side.

[0399] Optionally, determining a configuration of RS resources and corresponding multiple time unit offset values ​​according to the RRC signaling sent from the network side, and determining at least one set of time unit offset values ​​among the multiple time unit offset values ​​corresponding to at least some of the RS resources according to the MAC-CE signaling sent from the network side specifically includes determining a configuration of an RS resource set associated with an indicated RS resource according to the RRC signaling sent from the network side and multiple time unit offset values ​​corresponding to the RS resource set associated with the RS resource, and determining at least one set of time unit offset values ​​among the multiple time unit offset values ​​corresponding to the RS resource set associated with the RS resource according to the MAC-CE signaling sent from the network side.

[0400] Alternatively, the number of bits occupied by the first indication information in the DCI is a predefined fixed value, or the number of bits occupied by the first indication information in the DCI is determined based on the number of time unit offset values ​​included in each of the at least one set of time unit offset values. For example, the network side agrees with the UE that the first indication information occupies N bits (N is a positive integer) in the DCI. Usually, the first indication information has 1 bit, 2 bits, 3 bits, 4 bits, etc.

[0401] Optionally, the number of bits occupied by the first indication information in the DCI is determined based on the number of time unit offset values ​​included in each of the at least one set of time unit offset values, specifically, The number of bits occupied by the first indication information in the DCI is determined based on a maximum value of the number of time unit offset values ​​included in each of the at least one set of time unit offset values.

[0402] The number of bits occupied by the first indication information in the DCI is

[0403] Optionally, the number of bits occupied by the first indication information in the DCI is determined by RRC signaling or MAC-CE signaling sent from the network side.

[0404] Alternatively, the RS resource is a RS resource configured for the UE in one BWP / serving cell / frequency band.

[0405] Optionally, the set of time unit offset values ​​of the RS resources is determined based on the following information: (1) The maximum time unit offset value configured on the network side.

[0406] A set of time unit offset values ​​corresponding to an RS resource is a time unit offset value from the minimum time unit offset value to the maximum time unit offset value by default. The maximum time unit offset value is determined according to a DCI indication. Taking the time unit as a slot as an example, for example, 0 is the minimum slot offset value by default. According to the maximum slot value 3 of RS resource 1 configured by the network side device, the UE determines that a set of slot offset values ​​corresponding to the RS resource 1 are {0,1,2,3}.

[0407] Optionally, the maximum time unit offset value includes a maximum time unit offset value of an RS resource set associated with the RS resource, for example, an SRS resource, the maximum time unit offset value corresponding to each of one or more RS resource sets.

[0408] (2) The minimum and maximum time unit offset values ​​configured on the network side.

[0409] A set of time unit offset values ​​corresponding to an RS resource is a set of time unit offset values ​​from the configured minimum time unit offset value to the configured maximum time unit offset value. The minimum time unit offset value and the maximum time unit offset value are determined according to a DCI instruction. Taking the time unit as a slot as an example, for example, the UE determines that a set of slot offset values ​​corresponding to RS resource 1 are {2, 3, 4, 5, 6} according to the minimum slot offset value 2 and the maximum slot offset value 6 of RS resource 1 configured by the network side device.

[0410] Optionally, the minimum and maximum time unit offset values ​​of the RS resource include the minimum and maximum time unit offset values ​​of an RS resource set associated with the RS resource, and can be the minimum and maximum time unit offset values ​​corresponding to one or more RS resource sets, respectively, when the RS resource is exemplified as an SRS resource.

[0411] (3) The number of bits N occupied by the first indication information in the DCI.

[0412] A set of time unit offset values ​​corresponding to RS resources is set by default from the minimum time unit offset value.

number

[0413] Alternatively, if at least one set of time unit offset values ​​corresponding to an RS resource is one or more sets of time unit offset values ​​corresponding to an RS resource set associated with the RS resource, the set of time unit offset values ​​corresponding to the RS resource set is set by default from the minimum time unit offset value.

[0414] (4) The number of bits N occupied by the first indication information in the DCI, and a configured minimum time unit offset value.

[0415] A set of time unit offset values ​​corresponding to RS resources is calculated from the configured minimum time unit offset value.

number

[0416] Alternatively, if at least one set of time unit offset values ​​corresponding to an RS resource is one or more sets of time unit offset values ​​corresponding to an RS resource set associated with the RS resource, the set of time unit offset values ​​corresponding to the RS resource set is set by default from the minimum time unit offset value.

number

[0417] Optionally, determine a first time unit offset value corresponding to the RS resource according to first indication information in the DCI, including at least one of the following: (1) Determine a third RS resource for which at least one set of corresponding time unit offset values ​​is not configured, and adopt a pre-agreed time unit offset value for the third RS resource, where the pre-agreed time unit offset value is typically 0.

[0418] For example, the UE determines two RS resources, which correspond to RS resource 1 and RS resource 2, with time unit offset values ​​of {0, 1, 2, 3} and {1, 2}, respectively, according to the instruction of the network side device. When triggering RS resource 1 and RS resource 3 by DCI, the UE determines that the time unit offset value whose sequence is 2 is indicated by the first instruction information included in the DCI, and the time unit offset value corresponding to the RS resource 1 is 1. However, since the RS resource 3 does not have a corresponding time unit offset value configured, the time unit offset value corresponding to the RS resource 3 is the pre-agreed 0. Furthermore, the UE determines an RS resource set associated with a third RS resource, which does not have at least one corresponding set of time unit offset values ​​configured, and adopts the pre-agreed time unit offset value for the third RS resource set.

[0419] For example, the UE determines that the time unit offset values ​​corresponding to two RS resource sets RS set 1 and RS set 2 are {0, 1, 2, 3} and {1, 2}, respectively, according to an instruction from the network side device. When the UE triggers RS set 1 and RS set 3 by DCI, the UE determines that the time unit offset value whose sequence is 2 is indicated by the first instruction information included in the DCI, and the lot offset value corresponding to the RS set 1 is 1. However, no corresponding time unit offset value is configured for RS set 3, and the time unit offset value corresponding to RS set 3 is the pre-agreed 0.

[0420] Further, determine a third RS resource for which at least one set of time unit offset values ​​corresponding to a portion of the trigger condition is not configured, and adopt a pre-agreed time unit offset value for the third RS resource for which a set of time unit offset values ​​is not configured.

[0421] For example, the UE determines, according to the instruction of the network side device, that the time unit offset values ​​corresponding to RS resource 1 in trigger state 1 and trigger state 2 are {0, 1, 2, 3} and {1, 2}, respectively. When the UE triggers RS resource 1 in trigger state 3 by DCI, the corresponding time unit offset value of RS resource 1 in trigger state 3 is 0, which is pre-agreed.

[0422] Further, determine a third RS resource set associated with a third RS resource for which at least one set of time unit offset values ​​corresponding to a portion of the trigger condition is not configured, and adopt a pre-agreed time unit offset value for the third RS resource set for which a set of time unit offset values ​​is not configured.

[0423] For example, the UE determines, according to an instruction from the network side device, that the time unit offset values ​​corresponding to RS set 1 in trigger state 1 and trigger state 2 are {0, 1, 2, 3} and {1, 2}, respectively. When the UE triggers RS set 11 to trigger state 3 by DCI, the corresponding time unit offset value of RS set 11 in trigger state 3 becomes 0 as previously agreed upon.

[0424] (2) Determine a fourth RS resource for which there is no time unit offset value corresponding to the associated relationship indicated by the first instruction information in the corresponding set of first time unit offset values, and adopt a pre-agreed time unit offset value for the fourth RS resource, or adopt the minimum time unit offset value, maximum time unit offset value, or a time unit offset value at a specified position in the set of first time unit offset values ​​corresponding to the fourth RS resource.

[0425] For example, the UE determines time unit offset values ​​{0,1,2,3}, {1,2} corresponding to two RS resources, RS resource 1 and RS resource 2, according to an instruction from the network side device. When the UE triggers RS resource 1 and RS resource 2 by DCI, the UE determines that the time unit offset value having a sequence of 4 is indicated by the first instruction information included in the DCI, and that the lot offset value corresponding to the RS resource 1 is 3. However, RS resource 2 does not have a time unit offset value having a sequence of 4, and the time unit offset value corresponding to the RS resource 2 is the minimum time unit offset value 1.

[0426] Further, it determines that there is no fourth RS resource set in the corresponding first set of time unit offset values ​​associated with the fourth RS resource of the time unit offset value corresponding to the association relationship indicated by the first indication information, and adopts a pre-agreed time unit offset value for the fourth RS resource set, or adopts the minimum time unit offset value or the maximum time unit offset value or the time unit offset value at a specified position within the set of first time unit offset values ​​corresponding to the fourth RS resource set.

[0427] For example, the UE determines that the time unit offset values ​​corresponding to two RS resource sets RS set 1 and RS set 2 are {0, 1, 2, 3} and {1, 2}, respectively, according to an instruction from the network side device. When the UE triggers RS set 1 and RS set 2 by DCI, the UE determines that the time unit offset value whose sequence is 4 is indicated by the first instruction information included in the DCI, and the lot offset value corresponding to the RS set 1 is 3. However, RS set 2 does not have a time unit offset value whose sequence is 4, and the time unit offset value corresponding to RS set 2 is the maximum time unit offset value 2.

[0428] and determining a fourth RS resource for which no time unit offset value corresponding to the association relationship indicated by the first indication information exists, for some trigger states in the corresponding set of first time unit offset values, adopting a pre-agreed time unit offset value for the fourth RS resource in the trigger state for which no corresponding time unit offset value exists, or adopting a minimum time unit offset value, a maximum time unit offset value, or a time unit offset value at a designated position in the first set of time unit offset values ​​corresponding to the fourth RS resource.

[0429] For example, the UE determines, according to an instruction from the network side device, that the time unit offset values ​​corresponding to RS resource 1 in trigger state 1 and trigger state 2 are {0, 1, 2, 3} and {1, 2}, respectively. When the UE triggers RS resource 1 in trigger state 2 through DCI, the first instruction information included in the DCI indicates a time unit offset value whose sequence is 4, and the time unit offset value corresponding to RS resource 1 in trigger state 3 is 0 as previously agreed upon.

[0430] Also, determine a fourth RS resource set associated with a fourth RS resource for which there is no time unit offset value corresponding to the association relationship indicated by the first indication information in some trigger states in the corresponding first set of time unit offset values, and adopt a pre-agreed time unit offset value for the fourth RS resource set in the trigger state for which there is no corresponding time unit offset value, or adopt a minimum time unit offset value, a maximum time unit offset value, or a time unit offset value at a specified position in the first set of time unit offset values ​​corresponding to the fourth RS resource.

[0431] For example, the UE determines, according to an instruction from the network side device, that the time unit offset values ​​corresponding to RS set 1 in trigger state 1 and trigger state 2 are {0, 1, 2, 3} and {1, 2}, respectively. When the UE triggers RS set 1 in trigger state 2 by DCI, the first instruction information included in the DCI indicates a time unit offset value whose sequence is 4, and the time unit offset value corresponding to RS set 1 in trigger state 2 is the pre-agreed 0.

[0432] Next, the corresponding implementation of the above two examples on the UE side is described, and the corresponding implementation on the UE side and the network side is mainly described. For the repeated content, please refer to the corresponding part above. The following will not be repeated.

[0433] Example 1 In this example, the UE receives the configuration information of the SRS resource set and the DCI transmitted from the base station; The UE determines, according to the transmission slot indication in the DCI, the transmission slot of each aperiodic SRS resource set triggered by the DCI, where the transmission slot of each SRS resource set is a slot corresponding to a slot offset value corresponding to each SRS resource set determined according to a sequence number indicated by the transmission slot indication. As an example, the UE determines that SRS set 1 is transmitted on the first available slot from the reference slot corresponding to SRS set 1, and SRS set 2 is transmitted on the second available slot from the reference slot corresponding to SRS set 2.

[0434] Example 3 The UE receives the SRS resource set configuration information and the DCI transmitted from the base station.

[0435] The UE determines a transmission slot of each aperiodic SRS resource set triggered by the DCI based on the transmission slot indication information in the DCI, and the transmission slot of each SRS resource set is a slot corresponding to a slot offset value corresponding to each SRS resource set determined according to a sequence number indicated by the transmission slot indication information.

[0436] The UE determines that the transmission slots of each SRS resource set are (the slot offset value + 1) available slots from the reference slot corresponding to each SRS resource set determined by the sequence number indicated by the transmission slot indication information.

[0437] If a particular SRS resource set does not have a slot offset value of the sequence number indicated by the DCI, the slot offset value corresponding to the SRS resource set is a default value (e.g., 0). Nevertheless, assuming that the base station configures three aperiodic SRS resource sets (SRS set 1, SRS set 2, and SRS set 3) for the UE through RRC signaling, take as an example that the slot offset values ​​configured for the three SRS resource sets in trigger state 1 are {0, 1, 2, 3}, {1, 2}, and {2, 2, 4, 4}, respectively. Assume that the base station transmits one DCI to the UE for triggering aperiodic SRS transmission. The DCI triggers the transmission of SRS set 1 and SRS set 2 through trigger state 1, and the SRS transmission slot indication information in the DCI indicates sequence number 3. In this case, the slot offset value corresponding to SRS set 1 is the third slot offset value 2 configured in trigger state 1. In the case of trigger state 1, the third slot offset value does not exist in SRS set 2, so a default value is required. Optionally, the default value is the first slot offset value configured by the base station for the SRS resource set, in which case the slot offset value corresponding to SRS set 2 is 1. Optionally, the default value is 0, in which case the slot offset value corresponding to SRS set 2 is 0.

[0438] EMBODIMENT 2 The embodiment of the present invention further provides an apparatus for indicating an RS transmission position, which includes a memory 420, a transceiver 410 and a processor 400, as shown in FIG.

[0439] The memory 420 is configured to store a computer program, and the transceiver 410 is configured to transmit and receive data under the control of the processor 400, the processor 400 being configured to read the computer program in the memory and to perform the following operations: The processor 400 is configured to indicate to a UE at least one set of time unit offset values ​​corresponding to each configured RS resource; Trigger at least one RS resource in the RS resources by a DCI, and send first indication information via the DCI.
