Description

[Technical Field]

[0001] The embodiments of this application relate to the field of communications, and more specifically to wireless communication methods and equipment. [Background technology]

[0002] New Radio (NR) systems offer highly flexible system designs to support various possible deployment scenarios and diverse new service types in the future. For example, uplink and downlink resources can be directed and coordinated via upper-layer signaling and physical-layer signaling. Therefore, a single slot, or several symbols within a single slot, may be used for transmission in different directions at different times; for instance, it may be used for uplink transmission at one time and for downlink transmission at another.

[0003] However, for non-periodic sounding reference signals (SRS), the slot offset between the trigger signaling that triggers SRS transmission and the SRS transmission itself is configured by higher-layer signaling, such as Radio Resource Control (RRC) signaling. This means that the slot offset between each trigger signaling and the SRS transmission remains constant before the RRC signaling reconfigures the slot offset to another value. This fixes the relative position between the slot for receiving the trigger signaling and the slot for transmitting the SRS, increasing the limitations on non-periodic SRS triggering and corresponding SRS transmissions, and reducing the flexibility of the system.

Embodiments for Carrying Out the Invention

[0017] In the following, while referring to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments that can be obtained by those skilled in the art without creative efforts all belong to the protection scope of the present application.

[0018] FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0019] As shown in FIG. 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multiservice transmission is supported between the terminal device 110 and the network device 120.

[0020] It should be understood that while the embodiments of this application describe only communication system 100 as an example, the embodiments of this application are not limited to this. In other words, the technical solutions of the embodiments of this application can be applied to various communication systems, such as Long Term Evolution (LTE) systems, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G communication systems (also called New Radio (NR) communication systems), or future communication systems.

[0021] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with terminal devices 110. The access network device can provide communication coverage to a specific geographic area and can communicate with terminal devices 110 (e.g., UEs) located within that coverage area.

[0022] The network device 120 may be an evolutionary base station (Evolutional Node B, eNB, or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a radio controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, access point, in-vehicle device, or wearable device, hub, switch, bridge, router, or network device in a future evolving Public Land Mobile Network (PLMN).

[0023] The terminal device 110 may be any terminal device, including but not limited to terminal devices connected to the network device 120 or other terminal devices by wire or wireless connection.

[0024] For example, the terminal equipment 110 may refer to an access terminal, user equipment (UE), user unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. An access terminal may be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal equipment in a 5G network, or terminal equipment in a future evolving network.

[0025] The terminal device 110 may be used for device-to-device (D2D) communication.

[0026] The wireless communication system 100 may further include core network equipment 130 that communicates with a base station, and the core network equipment 130 may be 5G core network (5GC) equipment such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network equipment 130 may be an evolved packet core (EPC) device of an LTE network, for example, a session management function + core network data gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that SMF and PGW-C can implement. In the course of network evolution, the above-mentioned core network equipment may be called by other names, or the functions of the core network may be divided into new network entities, and are not limited to the embodiments of this application.

[0027] Each functional unit within the communication system 100 can further establish connections and achieve communication via a next-generation network (NG) interface.

[0028] For example, terminal equipment establishes an air interface connection with access network equipment via an NR interface to transmit user plane data and control plane signaling. Terminal equipment can establish a control plane signaling connection with the AMF via NG interface 1 (abbreviated as N1). Access network equipment such as next-generation radio access base stations (gNBs) can establish a user plane data connection with the UPF via NG interface 3 (abbreviated as N3). Access network equipment can establish a control plane signaling connection with the AMF via NG interface 2 (abbreviated as N2). The UPF can establish a control plane signaling connection with the SMF via NG interface 4 (abbreviated as N4). The UPF can exchange user plane data with the data network via NG interface 6 (abbreviated as N6). The AMF can establish a control plane signaling connection with the SMF via NG interface 11 (abbreviated as N11). The SMF can establish a control plane signaling connection with the PCF via NG interface 7 (abbreviated as N7).

[0029] Figure 1 illustrates one base station, one core network device, and two terminal devices, but the wireless communication system 100 may optionally include multiple base station devices, and the coverage range of each base station may include other numbers of terminal devices, and is not limited to the embodiments of this application.

[0030] It should be understood that, in the embodiments of this application, all devices with communication capabilities in a network / system may be referred to as communication devices. Taking the communication system 100 shown in Figure 1 as an example, the communication devices may include network devices 120 and terminal devices 110 with communication capabilities, and the network devices 120 and terminal devices 110 may be the devices described above, but will not be described again here. The communication devices may further include other devices in the communication system 100, such as other network entities, such as a network controller or a mobility management entity, and are not limited to the embodiments of this application.

[0031] It should be understood that the terms “system” and “network” as used herein are always interchangeable. The terms “and / or” as used herein simply describe the relationship between the related objects, indicating that three relationships are possible. For example, A and / or B can indicate three situations: A exists independently, A and B exist simultaneously, or B exists independently. Furthermore, the symbol “ / ” as used herein generally indicates that the preceding and following related objects are in an “or” relationship.

[0032] To facilitate understanding of the embodiments of this application, the SRS is introduced below.

[0033] The Sounding Reference Signal (SRS) is a crucial reference signal in 5G / NR systems and is widely used in various functions within NR systems. For example, SRS can be used in the following scenarios:

[0034] Scenario 1 involves using the UE sounding procedure for DL ​​CSI acquisition to obtain downlink channel status information.

[0035] In Scenario 2, it is used for uplink beam management and for frequency domain scheduling and precoding determination of uplink transmissions.

[0036] In Scenario 3, it is used for positioning.

[0037] Scenario 4 involves collaborating on codebook-based uplink transmission.

[0038] For example, it is used in frequency domain scheduling and determining Rank / precoding matrix indicator (PMI) / modulation coding scheme (MCS).

[0039] Scenario 5 involves collaborating on non-codebook-based uplink transmission.

[0040] For example, it is used for frequency domain scheduling and determining the Sounding Reference Signal Resource Indicator (SRI) / MCS.

[0041] Network equipment can be configured with one or more SRS resource sets per terminal device, and each SRS resource set can be configured with one or more SRS resources.

[0042] SRS transmission may be classified into periodic, semi-persistent, and aperiodic types.

[0043] Periodic SRS refers to SRS transmitted periodically, with its period and slot offset configured by RRC signaling. Once a terminal device receives the corresponding configuration parameters, it transmits SRS according to a fixed period until the RRC configuration becomes invalid. Spatial relation information for periodic SRS is also configured by RRC signaling. This spatial relation information can indicate a single Channel State Information Reference Signal (CSI-RS), a Synchronization Signal / Physical Broadcast Channel Block (SSB), or a reference SRS. For example, the transmit beam for periodic SRS may be implicitly indicated. For instance, a terminal device may determine the transmit beam for periodic SRS based on the indicated CSI-RS / SSB. As another example, a terminal device may determine the transmit beam used to transmit SRS in an SRS resource based on the spatial relation information of the SRS resource.

[0044] Semi-persistent SRS is also a periodically transmitted SRS, with the period and slot offset configured by RRC signaling, while its activation and deactivation signaling is carried by MAC CE. Terminal equipment begins transmitting the SRS after receiving the activation signaling and continues until it receives the deactivation signaling. Spatial-related information (transmit beam) for the semi-persistent SRS is carried together by MAC CE that activates the SRS.

[0045] TIFF0007870819000001.tif60170

[0046] Aperiodic SRS transmission refers to the ability of network devices to trigger SRS transmission from terminal devices via DCI. Trigger signaling for aperiodic SRS transmission may be carried by DCI for scheduling PUSCH / PDSCH in a dedicated UE search space or a common search space, or by DCI format2_3 in the common search space.

[0047] [Table 1]

[0048] As shown in Table 1, regarding the value of the SRS request field, for example, if the value of the SRS request field is 11, it indicates that SRS trigger signaling will use an SRS resource set with the upper-level parameter SRS resource trigger (aperiodicSRS-ResourceTrigger) set to 3.

[0049] After receiving a periodic SRS trigger signaling (e.g., DCI), the terminal device performs SRS transmission in the SRS resource set indicated by the trigger signaling. Here, the slot offset between the trigger signaling and the SRS transmission may be configured by upper-layer signaling (RRC). The network device pre-instructs the terminal device via upper-layer signaling on the configuration parameters of each SRS resource set, including time-frequency resources, sequence parameters, power control parameters, etc. Furthermore, for each SRS resource in the triggered SRS resource set, the terminal device can determine the transmit beam to be used to transmit SRS in that resource using spatial correlation information for that resource, and this spatial correlation information may be configured for each SRS resource by RRC.

[0050] As described above, for aperiodic sounding reference signals (SRS), the slot offset may be configured by higher-layer signaling, meaning that the slot offset between each trigger signaling and the SRS transmission remains constant before being reconfigured to other values ​​by RRC signaling. This fixes the relative position between the slot for receiving the trigger signaling and the slot for transmitting the SRS, increasing the limitations on aperiodic SRS triggers and corresponding SRS transmissions, and reducing the flexibility of the system.

[0051] For example, assuming a slot offset of k, if you want to trigger the transmission of an SRS in slot n+k, the corresponding trigger signaling can only be transmitted in slot n, which restricts the timing of the trigger signaling transmission and imposes unnecessary constraints on the scheduling of network equipment. As another example, if a slot or a symbol in a slot is dynamically changed from uplink transmission to downlink transmission, a certain aperiodic SRS may become untransmittable. For example, if slot n+k is changed to be used for downlink transmission, the trigger SRS signaling transmitted in slot n becomes invalid, or the trigger signaling cannot be transmitted in slot n.

[0052] Based on this, the present application introduces the dynamic indication of slot offsets by DCI. That is, each SRS resource set can constitute at least one (e.g., four) slot offsets, and network equipment can indicate which slot offset will ultimately be adopted by an indication field in the DCI. Selectively, the indication field may be designed to be up to two bits, in other words, each time a corresponding aperiodic SRS transmission is triggered, the corresponding indication field in the DCI can indicate one of the slot offsets.

[0053] Figure 2 shows a schematic flowchart of a wireless communication method 200 according to an embodiment of this application, and the method 200 can be performed interactively by a first device and a second device. The first device shown in Figure 2 may be the terminal device shown in Figure 1, and the second device shown in Figure 2 may be the access network device shown in Figure 1. Of course, both the first and second devices may be terminal devices, but this application is not limited to them.

[0054] As shown in Figure 2, method 200 may include S210 to S220.

[0055] In S210, the first control information transmitted by the second device is received.

[0056] Here, the first control information includes a first field and a second field, the first field being used to indicate that the first device is triggered to perform aperiodic SRS transmission based on at least one sounding reference signal SRS resource set.

[0057] In S220, aperiodic SRS transmission is performed in the first target slot based on the first SRS resource set within the at least one SRS resource set.

[0058] Here, the first SRS resource set is an SRS resource set comprising at least one slot offset within the at least one SRS resource set, the first control information further includes a second field, the second field is used to indicate a first slot offset corresponding to the first SRS resource set within the at least one slot offset, and the first target slot is determined based on the first slot offset and / or second slot offset.

[0059] In other words, the first device receives the first control information transmitted by the second device (the second device may be a network device or a second terminal device), and the first device determines the first slot offset corresponding to the first SRS resource set based on the value of the second field. Next, the first device determines the first target slot corresponding to the first SRS resource set based on the first slot offset and / or the second slot offset corresponding to the first SRS resource set. Finally, the first device performs aperiodic SRS transmission in the first target slot corresponding to the first SRS resource set.

[0060] For example, for a first SRS resource set configured with at least one slot offset, if the first slot offset corresponding to the first SRS resource set is not zero, the first target slot corresponding to the first SRS resource set may be determined based on the first slot offset corresponding to the first SRS resource set and the second slot offset corresponding to the first SRS resource set.

[0061] In this embodiment, the value of the second field is designed to be used to indicate a first slot offset within at least one configured slot offset for the triggered first SRS resource set, thereby avoiding a fixed slot offset between the trigger signaling and SRS transmission. In other words, the relative position between the slot for receiving the trigger signaling and the slot for transmitting the SRS becomes selectable or determinable, thereby reducing limitations on SRS transmission and improving system flexibility.

[0062] It should be noted that the at least one slot offset relating to this application is different from the second slot offset. That is, the second slot offset is something other than the at least one slot offset. Alternatively, for a first SRS resource set, the at least one slot offset and the second slot offset may be configured simultaneously. Of course, for a given SRS resource set, only one second slot offset may be configured, or neither the at least one slot offset nor the second slot offset may be configured, and this is not limited to this application. Optionally, the second slot offset may be configured by an RRC parameter of the SRS resource set, for example, the RRC parameter may be a slot offset parameter.

[0063] It should be noted that a second slot offset for a single SRS resource set always exists. For example, if an offset value is configured by RRC for the single SRS resource set, the second slot offset corresponding to the single SRS resource set may be the offset value configured by RRC, and if no offset value is configured by RRC, the second slot offset value corresponding to the single SRS resource set may be 0.

[0064] Furthermore, the first slot offset in this application may be 0. That is, for a first SRS resource set configured with at least one slot offset within the at least one SRS resource set, the first slot offset corresponding to the first SRS resource set may be 0, meaning that the first target slot corresponding to the first SRS resource set is determined based solely on the second slot offset corresponding to the first SRS resource set, or the second field or the first slot offset corresponding to the first SRS resource set is not considered when transmitting the first SRS resource set.

[0065] Of course, this application does not specifically limit the transmission method of an SRS resource set in which the at least one slot offset within the at least one SRS resource set is not configured.

[0066] For example, in one feasible configuration, if a certain SRS resource set does not have a first configuration field configured, i.e., if the SRS resource set does not have at least one slot offset configured, the first device can determine the slot corresponding to the SRS resource set based on the second slot offset corresponding to the SRS resource set, thereby performing SRS transmission in the slot corresponding to the SRS resource set. This is equivalent to being able to adopt a method of not using the transmission method based on the first slot offset for some SRS resource sets, i.e., not considering the second field, and to use the transmission method based on the first slot offset for other SRS resource sets, i.e., performing SRS transmission based on the value of the second field, which is advantageous in providing flexibility in network implementation.

[0067] Selectively, the aperiodic SRS transmission in this application is transmitted in the first BWP.

[0068] In other words, the at least one SRS resource set may be an SRS resource set corresponding to the first BWP.

[0069] Furthermore, it should be understood that the “correspondence” referred to in the embodiments of this application may indicate a direct or indirect correspondence between two things, or a related relationship between two things, or a relationship such as indicating and being indicated, or composing and being composed. The term “instruction” in the embodiments of this application may be direct instruction, indirect instruction, or a related relationship. For example, A instructing B may indicate that A directly instructs B, for example, that B can be obtained by A, or that A indirectly instructs B, for example, that A instructs C and B can be obtained by C, or that there is a related relationship between A and B. In some embodiments, the method 200 further This may include determining the number of bits to be occupied by the second field.

[0070] It should be noted that the term “number of bits occupied by the value of the second field” in this application can be understood as any other description having the same or similar meaning, such as the number of bits occupied by the second field or the size of the second field, and is not specifically limited in this application.

[0071] In some implementations, it is determined that the second field occupies 0 bits if the first instruction information has not been received by the first device, and / or if the second device has not transmitted or configured the first instruction information. Here, the first instruction information is used to indicate that the first control information includes the second field, or the first instruction information is used to indicate the number of bits to be occupied by the second field.

[0072] In this embodiment, the presence or absence of a second field in the first control information and / or the size of the second field can be determined based on the first instruction information transmitted by the second device. This is equivalent to the network being able to directly determine whether the second field exists or its size through signaling, thereby simplifying the design and reducing the complexity of terminal processing.

[0073] Selectively, the first instruction information is used to indicate that the first control information includes the second field. Selectively, when the first device receives the first instruction information, it decides that the second field occupies bits of a first quantity. For example, the first quantity may be 2 or another numerical value.

[0074] In this embodiment, the first instruction information is designed to be used to indicate that the first control information includes the second field, so that the second field can only be in two states: absent or present. This corresponds to the number of bits occupied by the second field being a fixed value, which is advantageous in reducing the signaling overhead of the first instruction information while also reducing the complexity of the protocol.

[0075] Selectively, the first instruction information is used to indicate the number of bits to be occupied by the second field. Selectively, if the first device receives the first instruction information and the first instruction information indicates a first value, it is determined that the second field occupies bits of a second quantity, and / or if the first device receives the first instruction information and the first instruction information indicates a second value, it is determined that the second field occupies bits of a third quantity. For example, the second quantity may be 1 or another numerical value, and the third quantity may be 2 or another numerical value.

[0076] In this embodiment, the first instruction information is designed to be used to indicate the number of bits occupied by the second field, so that the second field can be in three states, and in some cases, a 1-bit overhead in DCI can be saved.

[0077] Selectively, the first instruction information is transmitted by RRC signaling, or the first instruction information is transmitted by MAC CE signaling.

[0078] Of course, in other alternative embodiments, the first instruction information may also be used to indicate whether the first control information includes the second field, and is not specifically limited in this application.

[0079] In the embodiment, if the second field occupies 0 bits, the second field does not exist in the first control information.

[0080] In some implementations, the number of bits occupied by the second SRS resource set is determined based on a first configuration field of the second SRS resource set within all SRS resource sets configured with the at least one slot offset, where the first configuration field is used to configure the at least one slot offset for the SRS resource set.

[0081] In this embodiment, the presence or absence of the second field in the first control information and / or the size of the second field may be determined based on the configuration status of the first configuration field of the second SRS resource set in all SRS resource sets in which the at least one slot offset is configured, thereby avoiding the network equipment from transmitting information to determine the size of the second field, which is advantageous in saving signaling overhead.

[0082] It should be noted that the first SRS resource set relating to this application may be defined based on the first configuration field, and is not limited thereto. For example, the first SRS resource set is an SRS resource set configured with the first configuration field in at least one SRS resource set, the first configuration field being used to configure the at least one slot offset for the SRS resource set.

[0083] It should be explained that the first SRS resource set in this application is any SRS resource set in which the at least one slot offset is configured, within the at least one SRS resource set triggered by the first field, and the second SRS resource set in this application is any SRS resource set in which the at least one slot offset is configured. In this application, all SRS resource sets in which the at least one slot offset is configured may be all SRS resource sets at different granularities, and are not specifically limited in this application. For example, the first SRS resource set is an SRS resource set triggered by the first field, but this application does not limit whether the second SRS resource set is an SRS resource set triggered by the first field. That is, the second SRS resource set may be an SRS resource set triggered by the first field, or it may not be an SRS resource set triggered by the first field. Alternatively, all SRS resource sets configured with the at least one slot offset include the SRS resource sets configured with the at least one slot offset within the at least one SRS resource set triggered by the first field, i.e., all SRS resource sets configured with the at least one slot offset include all the first SRS resource sets. As another example, the second SRS resource set may include all SRS resource sets configured with the at least one slot offset, with a granularity of the first BWP corresponding to the at least one SRS resource set, all activated BWPs, all configured BWPs, the carriers where the first BWP is located, all activated carriers, or all configured carriers.

[0084] For example, the first configuration field can represent zero (i.e., none), one, two, three, or four values.

[0085] Selectively, the first configuration field is, It consists of at least one of the following: a list structure, a sequence structure, or a bitmap.

[0086] In this embodiment, designing the first configuration field as a list structure, a sequence structure, and a bitmap is advantageous in simplifying the signaling structure and reducing the complexity of terminal processing. Furthermore, designing the first configuration field as a bitmap provides excellent extensibility to the first configuration field, allowing it to be extended, for example, to four or more values.

[0087] As an example, the syntactic elements of the first configuration field will be described below, using the example that the first configuration field is composed of a sequence structure.

[0088] TIFF0007870819000003.tif51170

[0089] Here, the1stField represents the first constituent field. MaxValue1 represents the maximum value range for each element in the first constituent field, and optionally its value may be 4, 8, 16, or 32.

[0090] Of course, the position and maximum value range of the first constituent field described above are merely examples and should not be understood as limitations to this application.

[0091] For example, other alternative implementations may be included in the above-mentioned [[ ]], may be placed outside of it, or may have a single [[ ]] added independently.

[0092] TIFF0007870819000004.tif35170

[0093] Here, MaxValue1 represents the maximum value range for each element in the first constituent field, and selectively, its value may be 4, 8, 16, or 32, or 3, 7, 16, or 32, or even 3, 7, 15, or 31, and is not specifically limited in this application.

[0094] Selectively, the second SRS resource set is the SRS resource set with the largest number of slot offsets configured by the first configuration field among all SRS resource sets configured with at least one slot offset. For example, the number of bits occupied by the second field and the number of slot offsets configured in the second resource set are: 2 a ≥K, or 2 a It satisfies one of the conditions ≥ K+1.

[0095] Here, a represents the number of bits occupied by the second field, and K represents the number of slot offsets configured for the second SRS resource set.

[0096] As an example, if the at least one SRS resource set is M SRS resource sets in the first BWP, and a first configuration field is configured in N SRS resource sets out of the M SRS resource sets, then all SRS resource sets to which the at least one slot offset is configured are the N SRS resource sets, where each first configuration field is composed of k_1, k_2, ..., k_N elements, and K is denoted as the maximum value in {k_1, k_2, ..., k_N}, then the size of the second field is a bits, where a is 2 a ≥K or 2 a It is the smallest integer that satisfies the condition ≥ K+1. If the SRS resource set is configured such that the first configuration field does not exist (i.e., N=0), then a=0 (in this case K=0), meaning the second field does not exist.

[0097] Of course, in other alternative embodiments, the number of bits occupied by the second field does not have to be determined based on the first SRS resource set in the first BWP. For example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset is configured, in the SRS resource sets in all configured carriers (whether activated or not). As another example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset is configured, in all configured carriers or all activated carriers. As yet another example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset is configured, in the carrier where the first BWP is located.

[0098] Of course, as explained above, the number of bits occupied by the second field may be determined by the configuration of the first instruction information or the first configuration field of the second SRS resource set, but this application is not limited thereto. For example, in other alternative embodiments, the number of bits occupied by the second field may be set to a fixed value. Optionally, the fixed value may be a numerical value defined by the protocol.

[0099] In some embodiments, the method 200 further, If the number of the at least one slot offsets is equal to or greater than the value of the second field, the Xth slot offset in the at least one slot offset may be determined as the first slot offset, where X represents the value of the second field, or X represents the value of the second field plus 1.

[0100] In other words, if a first SRS resource set is configured with the first configuration field, the value of the second field corresponds to one element in the first configuration field. In this embodiment, determining the first slot offset using a fixed correspondence method is advantageous in reducing the complexity of protocol and product implementation.

[0101] For illustrative purposes, assuming the second field occupies 2 bits, the information in the second field could be 00, 01, 10, or 11, and its corresponding range of values ​​could be 0, 1, 2, or 3. For the sake of explanation, let us assume that at least one slot offset contains four slot offsets, each labeled A, B, C, and D. Optionally, X may be determined based on the index of the at least one slot offset. For example, if the index of the at least one slot offset starts from 0, then X represents the value of the second field, in which case the value of the second field is 0, corresponding to the 0th slot offset A; the value of the second field is 1, corresponding to the 1st slot offset B; the value of the second field is 2, corresponding to the 2nd slot offset C; and the value of the second field is 3, corresponding to the 3rd slot offset D. If the index of at least one of the slot offsets starts from 1, X represents the value of the second field plus 1, in which case the value of the second field is 0 and corresponds to the first slot offset A, the value of the second field is 1 and corresponds to the second slot offset B, the value of the second field is 2 and corresponds to the third slot offset C, and the value of the second field is 3 and corresponds to the fourth slot offset D.

[0102] In some implementations, the Xth slot offset within the at least one slot offset is determined as the first slot offset in either descending or ascending order. Alternatively, the Xth slot offset within the at least one slot offset is determined as the first slot offset according to the configuration order of the at least one slot offset.

[0103] For example, suppose that four slot offsets are configured for the first SRS resource set, and they are 0, 4, 2, and 1 respectively, then when arranged in ascending order, the first to fourth slot offsets are 0, 1, 2, and 4 respectively, and when arranged in descending order, the first to fourth slot offsets are 4, 2, 1, and 0 respectively, and according to the configuration order of the at least one slot offset, the first to fourth slot offsets are 0, 4, 2, and 1 respectively. Furthermore, when X=2, the first device can determine the Xth slot offset within the at least one slot offset as the first slot offset in ascending order, i.e., the first device can determine slot offset 1 as the first slot offset. Alternatively, the first device can determine the Xth slot offset within the at least one slot offset as the first slot offset in descending order, i.e., the first device can determine slot offset 2 as the first slot offset. Alternatively, the first device may determine the Xth slot offset within the at least one slot offset as the first slot offset, in accordance with the configuration order of the at least one slot offset; that is, the first device may determine slot offset 4 as the first slot offset.

[0104] Selectively, the configuration order of the at least one slot offset is the order of the at least one slot offset in the first configuration field of the first SRS resource set.

[0105] Selectively, the configuration order of the at least one slot offset may be the configuration order in the RRC signaling SRS-ResourceSet.

[0106] In some embodiments, the method 200 further, If the number of the at least one slot offsets is equal to or greater than the value of the second field, the first slot offset is determined based on a first correspondence, wherein the first correspondence includes the at least one value and the slot offsets corresponding to each of the at least one values, and the at least one value includes the value of the second field.

[0107] In other words, if a first SRS resource set is configured with the first configuration field, the value of the second field can correspond to one element in the first configuration field. In this embodiment, determining the first slot offset by a more flexible first correspondence is equivalent to determining the first slot offset by network-configured information, which is advantageous in improving the flexibility of the first slot offset.

[0108] For illustrative purposes, assuming that the second field occupies 2 bits, the range of values ​​for the second field can include 00, 01, 10, and 11, and that the first configuration field of a first SRS resource set constitutes four first slot offsets, each denoted as slot offset 1, slot offset 2, slot offset 3, and slot offset 4. In this case, the first correspondence can include slot offset 1 corresponding to 00, slot offset 2 corresponding to 01, slot offset 3 corresponding to 10, and slot offset 4 corresponding to 11. If the value of the second field is 00, then slot offset 1 corresponding to 00 can be determined as the first slot offset.

[0109] Selectively, different first SRS resource sets within the at least one SRS resource set may correspond to different or the same first correspondence.

[0110] Selectively, the first correspondence is defined by a protocol or configured by the second device.

[0111] It should be explained that, in the embodiments of this application, “defined by protocol” may mean defined by protocol. Optionally, “protocol” may refer to standard protocols in the field of communications, including, for example, LTE protocols, NR protocols, and related protocols applicable to future communications systems, but is not specifically limited in this application.

[0112] Selectively, the first correspondence is comprised of wireless resource control (RRC) signaling or media access control element (MAC CE).

[0113] In some embodiments, the method 200 further, If the number of at least one slot offset is less than or equal to the value of the second field, or less than the value of the second field, This may include determining the mod(Y,N)-th slot offset or mod(Y,N)+1-th slot offset within the at least one slot offset as the first slot offset, where Y represents the value of the second field, or Y represents the value of the second field plus 1, N represents the number of the at least one slot offset, and mod represents the modulo operation; determining the N-th slot offset within the at least one slot offset as the first slot offset; determining the 1st slot offset within the at least one slot offset as the first slot offset; determining the first slot offset as 0; or not considering the second field when transmitting the first SRS resource set; or not considering the first slot offset when transmitting the first SRS resource set.

[0114] In other words, if the value of the second field (denoted as Y) is equal to or greater than the number of elements in the first constituent field (denoted as N), or greater than the number of elements in the first constituent field, the first device, One of the following can be performed: determine the mod(Y,N)-th slot offset or mod(Y,N)+1-th slot offset within the at least one slot offset as the first slot offset, where Y represents the value of the second field, or Y represents the value of the second field plus 1, N represents the number of the at least one slot offset, and mod represents the modulo operation; determine the N-th slot offset within the at least one slot offset as the first slot offset; determine the 1st slot offset within the at least one slot offset as the first slot offset; determine the first slot offset as 0; or disregard the second field when transmitting the first SRS resource set; or disregard the first slot offset when transmitting the first SRS resource set.

[0115] For example, if the number of the at least one slot offset starts from 0, the mod(Y,N)-th slot offset within the at least one slot offset is determined as the first slot offset. If the number of the at least one slot offset starts from 1, the mod(Y,N)+1-th slot offset within the at least one slot offset is determined as the first slot offset.

[0116] For the sake of explanation, the first slot offset will be determined below based on one of the numbering schemes (for example, either the numbering of at least one slot offset starts from 1, or the numbering of at least one slot offset starts from 0). For solutions to determine the first slot offset based on the other numbering scheme, refer to the relevant content. In other words, the first slot offset can be determined based on the other numbering scheme by similar solutions. To avoid redundancy, solutions to determine the first slot offset based on the other numbering scheme will not be described again thereafter.

[0117] In this embodiment, the mod(Y,N)-th slot offset or mod(Y,N)+1-th slot offset within the at least one slot offset is determined as the first slot offset, and even if the value of the second field (denoted as Y) is greater than or equal to the number of elements in the first constituent field (denoted as N) or greater than the number of elements in the first constituent field, the same or different first slot offsets can be indicated by taking different values ​​for the second field, which is advantageous in improving the indicating effect of the second field. Determining the N-th slot offset within the at least one slot offset as the first slot offset, or determining the first slot offset as 0, or not considering the second field when transmitting the first SRS resource set, or not considering the first slot offset when transmitting the first SRS resource set, is advantageous in simplifying the process of determining the first slot offset, and is further advantageous in reducing the complexity of protocol and product implementation.

[0118] For illustrative purposes, assuming that the first SRS resource set in the at least one SRS resource set comprises two slot offsets (denoted as the first slot offset and the second slot offset, respectively), the second field occupies two bits, and the value of the second field may be in the range of 0, 1, 2, or 3, where Y represents the value of the second field, and the second field with values ​​of 0 and 1 is used to indicate the two slot offsets, respectively. In this case, if the value of the second field is 0, the slot offset corresponding to the first SRS resource set is the first slot offset of the two slot offsets. If the value of the second field is 1, the first slot offset corresponding to the first SRS resource set is the second slot offset of the two slot offsets.

[0119] If the value of the second field is 2, the second field may be used to indicate any one of the following:

[0120] Of the two slot offsets, the mod(2,2)+1 slot offset is determined as the first slot offset, that is, the first slot offset of the two slot offsets is determined as the first slot offset, or the second slot offset of the at least one slot offset is determined as the first slot offset, or the first slot offset within the at least one slot offset is determined as the first slot offset, or the first slot offset is determined as 0, or the second field is not considered when transmitting the first SRS resource set, or the first slot offset is not considered when transmitting the first SRS resource set.

[0121] If the value of the second field is 3, the second field may be used to indicate any one of the following:

[0122] Of the two slot offsets, the mod(3,2)+1 slot offset is determined as the first slot offset, that is, the second slot offset of the two slot offsets is determined as the first slot offset, or the second slot offset within at least one slot offset is determined as the first slot offset, or the first slot offset within at least one slot offset is determined as the first slot offset, or the first slot offset is determined as 0, or the second field is not considered when transmitting the first SRS resource set, or the first slot offset is not considered when transmitting the first SRS resource set.

[0123] Simply put, in this embodiment, if the value of the second field is 0, it can correspond to the first slot offset. If the value of the second field is 1, it can correspond to the second slot offset. If the value of the second field is 2, it can correspond to the first slot offset by modulo calculation. If the value of the second field is 3, it can correspond to the second slot offset by modulo calculation.

[0124] It should be explained that, generally, different SRS resource sets in the multiple SRS resource sets must be transmitted in different slots or in the same slot with different symbols. However, even if the slot offsets corresponding to the multiple SRS resource sets are different, it cannot be guaranteed that the multiple SRS resource sets are not in the same slot. However, in this embodiment, for the first SRS resource set, the corresponding first target slot is determined based on the first slot offset, based on the second slot offset. Therefore, this application does not require the first slot offsets corresponding to different first SRS resource sets in the multiple first SRS resource sets; that is, the first slot offsets corresponding to different first SRS resource sets in the multiple first SRS resource sets may be the same or different. For example, if the value of the second field (denoted as Y) is greater than or equal to the number of elements in the first constituent field (denoted as N) or greater than the number of elements in the first constituent field, the same or different first slot offsets can be indicated by taking different values ​​for the second field.

[0125] In some implementations, the first slot offset is determined to be the mod(Y,N)-th slot offset or mod(Y,N)+1-th slot offset within the at least one slot offset, in descending order or in ascending order, or the first slot offset is determined to be the mod(Y,N)-th slot offset or mod(Y,N)+1-th slot offset within the at least one slot offset, in accordance with the configuration order of the at least one slot offset.

[0126] For example, suppose the first SRS resource set has four slot offsets, which are 0, 4, 2, and 1. In this case, if arranged in ascending order, the first to fourth slot offsets are 0, 1, 2, and 4 respectively. If arranged in descending order, the first to fourth slot offsets are 4, 2, 1, and 0 respectively. In accordance with the configuration order of the at least one slot offset, the first to fourth slot offsets are 0, 4, 2, and 1 respectively. Furthermore, if mod(Y,N)+1=2, the first device can determine the mod(Y,N)+1 slot offset from the at least one slot offset as the first slot offset, i.e., the first device can determine slot offset 1 as the first slot offset. Alternatively, the first device can determine the mod(Y,N)+1 slot offset from the at least one slot offset as the first slot offset, i.e., the first device can determine slot offset 2 as the first slot offset. Alternatively, the first device may determine the mod(Y,N)+1 slot offset among the at least one slot offset as the first slot offset, in accordance with the configuration order of the at least one slot offset; that is, the first device may determine slot offset 4 as the first slot offset.

[0127] Selectively, the configuration order of the at least one slot offset may be the configuration order in the RRC signaling SRS-ResourceSet.

[0128] In some embodiments, all of the first SRS resource sets in the at least one SRS resource set are configured with the same number of slot offsets, or all of the SRS resource sets in the at least one SRS resource set are configured with the same number of slot offsets.

[0129] In this embodiment, the first SRS resource set is designed to have the same number of slot offsets, which means that the same number of elements are configured in the first configuration field in all SRS resource sets in which the first configuration field is configured. In other words, by constraining the configuration, it is advantageous to reduce the complexity of the network configuration and the complexity of implementing network equipment.

[0130] Similarly, the SRS resource sets in at least one of the SRS resource sets are designed to have the same number of slot offsets, which corresponds to the same number of elements being configured in the first configuration field in all SRS resource sets. This similar constraint on the configuration is advantageous in reducing the complexity of the network configuration and the complexity of implementing network equipment.

[0131] In some embodiments, the first SRS resource set includes 2 a A set of individual slot offsets is configured, where a represents the number of bits occupied by the second field.

[0132] In this embodiment, the first SRS resource set includes 2 a It is designed so that a number of slot offsets are configured, and this means that the first configuration field is 2 in all SRS resource sets where the first configuration field is configured. a This corresponds to the individual elements being composed, which is advantageous for simplifying protocol design, avoiding several subsequent additional rules, and thereby reducing the complexity of product implementation.

[0133] In some embodiments, the method 200 further, The first target slot is determined based on a first slot and the first slot offset, wherein the first slot is determined by the slot in which the first control information is located and the second slot offset.

[0134] In some implementations, the first target slot is determined to be the Tth available slot, starting from the first slot, where T represents the first slot offset.

[0135] Selectively, if T=0, the Tth available slot, starting from the first slot, is the first slot.

[0168] In some embodiments, the method 200 further, Receiving configuration information transmitted by the second device, wherein the configuration information is used to configure one or more SRS resource sets, each SRS resource set in the one or more SRS resource sets comprises at least one SRS resource, and the one or more SRS resource sets comprises the at least one SRS resource set.

[0169] Exemplary, the first device receives configuration information transmitted by the second device (which may be a network device or a second terminal device) via RRC signaling, and the configuration information is used to constitute one or more SRS resource sets, each SRS resource set containing one or more SRS resources, each SRS resource consisting of an RRC signaling SRS-Resource, and each SRS resource set is aperiodic, i.e., the resource type (resourceType) corresponding to each SRS resource set is aperiodic. Here, the first SRS resource set is one of the one or more SRS resource sets.

[0170] Selectively, the at least one SRS resource set includes a plurality of SRS resource sets whose application field is configured as antenna switching, and different SRS resource sets in the plurality of SRS resource sets correspond to different transmission slots. Here, the plurality of SRS resource sets correspond to a certain "xTyR" type antenna switching configuration.

[0171] Illustratively, the usage field of some of the SRS resource sets in the at least one SRS resource set is configured as antenna switching, or the usage field of all SRS resource sets in the at least one SRS resource set is configured as antenna switching. Illustratively, the plurality of SRS resource sets correspond to an antenna switching configuration of a certain "xTyR" type. Illustratively, an SRS resource set within the one or more SRS resource sets may be configured as any one of {beamManagement, codebook, nonCodebook, antennaSwitching}.

[0172] It should be understood that if one of the SRS resource sets among the plurality of SRS resource sets is the first SRS resource set described above, then the transmission slot is the first target slot. If one of the SRS resource sets among the plurality of SRS resource sets is the third SRS resource set described later, then the transmission slot is the second target slot.

[0173] Selectively, a corresponding trigger state is configured for each SRS resource set within the plurality of SRS resource sets.

[0174] In this embodiment, different trigger states can be configured for the SRS resource sets within the plurality of SRS resource sets, which is advantageous for relaxing protocol limitations and increasing network configuration and trigger flexibility.

[0175] Illustratively, one or more (denoted as M) trigger states are configured in the SRS resource sets within the plurality of SRS resource sets, where each trigger state corresponds to one value in the SRS request field in DCI, i.e., one code point. Optionally, the one or more trigger states may be configured by an aperiodic SRS resource set trigger (aperiodicSRS-ResourceTrigger) and an aperiodic SRS resource set trigger list (aperiodicSRS-ResourceTriggerList) in the SRS resource set cell (SRS-ResourceSet IE), where one value is configured in aperiodicSRS-ResourceTrigger and one or more values ​​are configured in aperiodicSRS-ResourceTriggerList.

[0176] Selectively, the same number of slot offsets are configured for the multiple SRS resource sets. Here, the multiple SRS resource sets correspond to a certain "xTyR" type antenna switching configuration.

[0177] In this embodiment, the multiple SRS resource sets are designed to have the same number of slot offsets, which reduces the complexity of terminal antenna switching by adding constraints.

[0178] In some embodiments, the method 200 further, This may include reporting the capability information of the first device.

[0179] Here, the capability information is used to indicate that the first device supports configuring a first configuration field for an SRS resource set, the first configuration field is used to configure a slot offset for the SRS resource set, and / or the capability information is used to indicate that the first device supports including the second field in the control information, and / or the capability information is used to indicate that the first device supports dynamic slot offsets.

[0180] Of course, in other alternative embodiments, the capability information may be used to indicate whether the first device supports configuring a first configuration field for an SRS resource set, the first configuration field being used to configure a slot offset for the SRS resource set, and / or the capability information may be used to indicate whether the first device supports including the second field in the control information, and / or the capability information may be used to indicate whether the first device supports dynamic slot offsets, and / or are not limited to the present application.

[0181] Selectively, the capability information is reported by wireless resource control (RRC) signaling or media access control element (MAC CE).

[0182] Selectively, the capability information of the first device may be reported in accordance with one of the following methods:

[0183] The capability information is reported for each combination of frequency bands, or The capability information is reported for each frequency band range, or Report the capability information for each frequency band, or Report the aforementioned capability information to each carrier, or The aforementioned capability information is reported to each terminal device.

[0184] In this embodiment, the capability information is designed to be reported per frequency band, meaning that different frequency bands can independently report their corresponding capabilities (per band). This allows the first device to achieve a greater degree of freedom; for example, the first device may support dynamic slot offset in some frequency bands and not in others, thereby enabling more first devices to support dynamic slot offset.

[0185] The capability information is designed to be reported for each band combination, meaning that different band combinations can be reported independently (per band per band combination). This allows the first instrument to achieve a greater degree of freedom. For example, the first instrument may support dynamic slot offset for some or more band combinations and not for others, thereby enabling more first instruments to support dynamic slot offset.

[0186] The capability information is designed to be reported independently according to each frequency band in a band combination, meaning that frequency bands in different band combinations can be reported independently. This allows the first instrument to achieve a greater degree of freedom. For example, the first instrument may not support dynamic slot offset in one CA, but may support dynamic slot offset in several frequency bands in another CA combination, thereby enabling more first instruments to support dynamic slot offset.

[0187] The capability information is designed to be reported independently according to each carrier in each frequency band in a band combination, meaning that different carrier CCs in different frequency band combinations can be reported independently (per CC per band per band combination). This allows the first instrument to achieve a greater degree of freedom, thereby enabling more first instruments to support dynamic slot offsets, as different frequency band combinations can be reported independently and different carriers in a single frequency band can also be reported independently.

[0188] The capability information is designed to be reported according to the frequency range, meaning that different FRs can be reported independently (per FR). For example, FR1 and FR2 can be reported independently, allowing the first instrument to achieve a greater degree of freedom. For instance, the first instrument may not support dynamic slot offset at low frequencies (FR1) but may support dynamic slot offset at FR2 (high frequencies), thereby enabling more first instruments to support dynamic slot offset.

[0189] The capability information is designed to be reported to the UE (per UE), meaning that when the UE reports the capability information, this capability can be supported in each frequency band, and the signaling overhead of capability reporting by the first device can be reduced.

[0190] Selectively, the capability information can be reported for each combination of frequency bands according to one of the following methods:

[0191] For each frequency band in each of the aforementioned combinations of frequency bands, report the capability information, or The capability information is reported for each carrier in each frequency band in each of the aforementioned combinations of frequency bands.

[0192] In some embodiments, the first control information is at least one of the following formats: downlink control information format 0_1 ​​(DCI format 0_1), downlink control information format 0_2 (DCI format 0_2), downlink control information format 1_1 (DCI format 1_1), downlink control information format 1_2 (DCI format 1_2), or downlink control information format 2_3 (DCI format 2_3).

[0193] In some embodiments, aperiodic SRS transmission is performed in the second target slot based on the third SRS resource set within the at least one SRS resource set.

[0194] Here, the third SRS resource set is an SRS resource set within the at least one SRS resource set in which the at least one slot offset does not constitute, and the second target slot is determined based on the second slot offset.

[0195] In other words, the third SRS resource set is an SRS resource set in which the first configuration field in the at least one SRS resource set is not configured, and the first configuration field is used to configure the at least one slot offset for the SRS resource set.

[0196] It should be noted that the second slot offset corresponding to the third SRS resource set always exists. For example, if an offset value is configured by RRC for the third SRS resource set, the second slot offset corresponding to the third SRS resource set may be the offset value configured by RRC, and if no offset value is configured by RRC, the second offset value corresponding to the third SRS resource set may be 0.

[0201] In the following, we will explain the solution of this application by combining specific embodiments, using the example that the first device is a terminal device and the second device is a network device.

[0202] The terminal device reports capability information to the network device, the capability information is used to indicate that the terminal device supports configuring a first configuration field for an SRS resource set, the first configuration field is used to configure a slot offset for the SRS resource set, and / or the capability information is used to indicate that the terminal device supports including the second field in the control information, and / or the capability information is used to indicate that the terminal device supports dynamic slot offsets.

[0203] The network device configures three (three as an example, but there may be more) aperiodic SRS resource sets (referred to as SRS resource set 1, SRS resource set 2, and SRS resource set 3, respectively) for the first BWP on the terminal device, that is, the resourceType in each SRS resource set is configured as aperiodic. Here, the first configuration field is not configured in SRS resource set 1, the first configuration field of SRS resource set 2 shows two elements (the first and second elements are referred to as x0 and x1, respectively), and the first configuration field of SRS resource set 3 shows four elements (the first to fourth elements are referred to as y0, y1, y2, and y3, respectively).

[0204] The network device transmits the first control information to the terminal device, triggering a periodic SRS transmission in the first BWP, where the second field of the first control information occupies bit a.

[0205] Here, the number of a bits is determined based on one of the following methods.

[0206] Method 1 The terminal device can determine the number of bits to be occupied in the second field based on the first instruction information.

[0207] Here, the first instruction information is used to indicate that the first control information includes the second field. Specifically, if the terminal device has not received the first instruction information, it is determined that the second field occupies 0 bits, and / or if the network device has not transmitted or configured the first instruction information, it is determined that the second field occupies 0 bits, and / or if the terminal device has received the first instruction information, it is determined that the second field occupies bits of a first quantity. For example, the first quantity may be 2 or another numerical value. In this embodiment, since the first instruction information is designed to be used to indicate that the first control information includes the second field, the second field can only have two states: it does not exist and it exists, which corresponds to the number of bits occupied by the second field being a fixed value, which is advantageous in reducing the signaling overhead of the first instruction information while also reducing the complexity of the protocol.

[0208] Exemplary, by combining these embodiments, the number of a bits can be determined according to the following method.

[0209] In method 1-1, if the terminal device has not received the first instruction information transmitted from the network device, or if the network device has not transmitted or configured the first instruction information, the size of the second field is 0 bits, i.e., it does not exist.

[0210] In method 1-2, when a network device transmits or configures first instruction information to a terminal device, or when a terminal device receives first instruction information transmitted or configured by a network device, the size of the second field is 2 bits.

[0211] Method 2 The terminal device determines the number of bits to be occupied in the second field based on the first instruction information.

[0212] Here, the first instruction information is used to indicate the number of bits to be occupied by the second field. Selectively, if the terminal device has not received the first instruction information, it is determined that the second field will occupy 0 bits, and / or if the network device has not transmitted or configured the first instruction information, it is determined that the second field will occupy 0 bits, and / or if the terminal device has received the first instruction information and the first instruction information indicates a first value, it is determined that the second field will occupy bits of a second quantity, and / or if the terminal device has received the first instruction information and the first instruction information indicates a second value, it is determined that the second field will occupy bits of a third quantity. For example, the second quantity may be 1 or another numerical value, and the third quantity may be 2 or another numerical value. In this embodiment, since the first instruction information is designed to be used to indicate the number of bits to be occupied by the second field, the second field can have three situations, and in some cases, one bit of overhead in DCI can be saved.

[0213] In method 2-1, if the terminal device has not received the first instruction information transmitted from the network device, or if the network device has not transmitted or configured the first instruction information, the size of the second field is 0 bits, i.e., it does not exist.

[0214] In method 2-2, if a network device transmits or configures first instruction information to a terminal device, or a terminal device receives first instruction information transmitted or configured by a network device, and the first instruction information is a first value, the size of the second field is 1 bit.

[0215] In method 2-3, if a network device transmits or configures first instruction information to a terminal device, or a terminal device receives first instruction information transmitted or configured by a network device, and the first instruction information is a second value, the size of the second field is 2 bits.

[0216] Method 3 The terminal device determines the number of bits occupied by the second field based on the first configuration field of the second SRS resource set in all SRS resource sets configured with the at least one slot offset, where the first configuration field is used to configure the at least one slot offset for the SRS resource set. In this embodiment, the presence or absence of the second field in the first control information and / or the size of the second field may be determined based on the configuration status of the first configuration field of the second SRS resource set in all SRS resource sets configured with the at least one slot offset, avoiding the need for the network device to transmit information for determining the size of the second field, which is advantageous for saving signaling overhead.

[0217] For example, the terminal device determines the number of bits occupied by the second field based on the number of slot offsets configured in the second SRS resource set, where the second SRS resource set is the SRS resource set with the largest number of slot offsets configured by the first configuration field among all SRS resource sets configured with the at least one slot offset. For example, the number of bits occupied by the second field and the number of slot offsets configured in the second resource set satisfy one of the following conditions: 2 a ≧K, or 2 a ≧K + 1.

[0218] Here, a represents the number of bits occupied by the second field, and K represents the number of slot offsets configured for the second SRS resource set.

[0219] As an example, suppose that the at least one SRS resource set is M SRS resource sets in the first BWP, and N of the M SRS resource sets constitute the first configuration field, and all SRS resource sets to which the at least one slot offset is configured are the N SRS resource sets, where each first configuration field consists of k_1, k_2, ..., k_N elements, and K is the maximum value in {k_1, k_2, ..., k_N}, then the size of the second field is a bits, where a is 2 a ≥K or 2 a It is the smallest integer that satisfies the condition ≥ K+1. If there is no first configuration field in the SRS resource set configuration (i.e., N=0), then a=0 (in this case K=0), meaning the second field does not exist.

[0220] Of course, in other alternative embodiments, the number of bits occupied by the second field does not have to be determined based on the first SRS resource set in the first BWP. For example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset in the SRS resource set is configured for all configured carriers (whether activated or not). As another example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset in all configured carriers or all activated carriers is configured. As yet another example, the number of bits occupied by the second field may further be determined based on the SRS resource set in which the at least one slot offset is configured for the carrier where the first BWP is located.

[0221] By combining these embodiments, the number of a bits can be determined according to the following method.

[0222] The terminal device can be determined based on the maximum number of elements indicated by the first configuration field in the three SRS resource sets, i.e., the maximum number is 4. In this case, the number of bits occupied by the second field and the number of slot offsets configured in the second resource set are 2. a The condition ≥ K is satisfied, where a represents the number of bits occupied by the second field and K represents the number of slot offsets configured for the second SRS resource set. That is, 2 2 = 4, meaning the size of the second field is 2 bits.

[0223] Example 1 In this embodiment, with respect to the third SRS resource set in the above-mentioned at least one SRS resource set, the terminal device can perform aperiodic SRS transmission based on the third SRS resource set in the second target slot, where the third SRS resource set is an SRS resource set within the at least one SRS resource set that does not constitute the at least one slot offset, and the second target slot is determined based on the second slot offset.

[0224] By combining these embodiments, the SRS resource set 1 can be used as an example of the third SRS resource set described above.

[0233] If the number of the at least one slot offset configured in the SRS resource set 2 (i.e., 2) is less than or equal to the value of the second field, then perform one of the following (assuming in the example below that x0 and x1 correspond to the first and second slot offsets, respectively):

[0234] In Method 1, The first slot offset is determined to be the modulo(Y,N)+1 slot offset among the at least one slot offsets, where Y represents the value of the second field, or Y represents the value of the second field plus 1, N represents the number of the at least one slot offset, and mod represents the modulo operation. For example, when f=2, it corresponds to x0 (denoted as T), and mod(2,2)+1=1. As another example, when f=3, it corresponds to x1 (denoted as T), and mod(3,2)+2=2.
