[0119] In some embodiments, network devices (e.g., access network devices, core network devices, etc.) can activate or deactivate resources used by the terminal to transmit uplink reference signals. When the resource is activated, the terminal can transmit uplink reference signals on that resource for the network device to perform location operations, such as locating the terminal or other devices based on the received uplink reference signals. When the resource is deactivated, the terminal stops transmitting uplink reference signals on that resource.

[0120] In some embodiments, the uplink reference signal includes, but is not limited to, a sounding reference signal (SRS). The network device can configure at least one SRS resource set for the terminal. An SRS resource set may include one or more SRS resources. The network device can activate or deactivate the SRS resources in the SRS resource set by indicating to the terminal the identifier (ID) of the activated or deactivated SRS resource set.

[0121] In some embodiments, there are some technical issues because the identifier of an SRS resource set is only unique within the corresponding bandwidth range.

[0122] Taking the Bandwidth Part (BWP) as an example, the network device configures four SRS resource sets for the terminal in BWP#1, labeled 1, 2, 3, and 4. When the terminal only sends SRS in BWP#1, the SRS resource set identifier can be considered unique. The network device indicates any one of the SRS resource set identifiers 1 to 4, and the terminal can determine which SRS resource set needs to be activated or deactivated. For example, if the network device indicates that the SRS resource set identifier 2 needs to be deactivated, the terminal can determine that the SRS resource set with identifier 2 associated with BWP#1 needs to be deactivated.

[0123] However, in some embodiments, the terminal may use bandwidth aggregation to send uplink reference signals. In this case, the network device may configure at least one SRS resource set for the terminal on multiple aggregated bandwidths, which will result in the SRS resource set identifier not being unique.

[0124] For example, the aggregated bandwidth includes two BWPs, BWP#1 and BWP#2. The network device configures four SRS resource sets for the terminal in BWP#1, labeled 1, 2, 3, and 4, and three SRS resource sets for the terminal in BWP#2, labeled 1, 2, and 3. When the network device indicates any of the SRS resource set labels 1 through 3, the terminal cannot determine which SRS resource set needs to be activated or deactivated. For instance, if the network device indicates that the SRS resource set to be deactivated is labeled 2, the terminal cannot determine whether to deactivate the SRS resource set labeled 2 in the SRS resource set associated with BWP#1, or the SRS resource set labeled 2 in the SRS resource set associated with BWP#2.

[0169] Figure 2 For related embodiments of the first device, the second device, and the terminal, please refer to the embodiments described below, which will not be repeated here.

[0170] Figure 3 This is a schematic flowchart illustrating an activation control method according to an embodiment of the present disclosure. The activation control method shown in this embodiment can be executed by a first device, which can communicate with a second device.

[0171] like Figure 3 As shown, the activation control method may include the following steps:

[0172] In step S301, a first indication message is sent to the second device, wherein the first indication message is used to instruct the second device to activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth.

[0173] It should be noted that, Figure 3 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0174] In some embodiments, when the first device instructs the second device to activate or deactivate the first uplink reference signal resource of the terminal, it may send first indication information to the second device. The first indication information may instruct the second device to activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth. The first uplink reference signal resource includes resources used by the terminal to transmit uplink reference signals.

[0175] Since the first instruction information does not merely instruct the second device to activate or deactivate a certain uplink reference signal resource of the terminal, but rather instructs the second device to activate or deactivate the first uplink reference signal resource associated with the first bandwidth, it is easier for the second device to accurately determine which uplink reference signal resource associated with the first bandwidth to activate or deactivate. This helps to avoid the difficulty in accurately determining which uplink reference signal resource needs to be activated or deactivated when the terminal uses bandwidth aggregation to send uplink reference signals.

[0176] In some embodiments, bandwidth aggregation can realize the aggregation of uplink reference signals. Taking the uplink reference signal including SRS as an example, bandwidth aggregation can realize the aggregation of SRS resources in SRS resource sets configured on different carriers, or the aggregation of SRS resources configured on different carriers.

[0177] In some embodiments, the first device includes a core network device and the second device includes an access network device; or, the first device includes a Central Unit (CU) access network device, such as a gNB-CU, and the second device includes a Distributed Unit (DU) access network device, such as a gNB-DU.

[0178] For example, the core network device can send a first indication message to the access network device, which can then activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth according to the first indication. In some embodiments, the core network device includes, but is not limited to, a Location Management Function (LMF) and an Access Management Function (AMF).

[0179] For example, in a separate radio access network architecture, the gNB-CU can send a first indication message to the gNB-DU, and the gNB-DU can activate or deactivate the first uplink reference signal resource associated with the first bandwidth of the terminal according to the first indication. In some embodiments, the gNB-CU can receive the first indication message from the core network equipment.

[0180] The first indication information is carried in at least one of the following: New Radio Positioning Protocol A (NRPPa) message; F1AP (F1 Application Protocol) message.

[0181] For example, if the first device includes a core network device and the second device includes an access network device, the core network device can send the first indication information to the access network device via an NRPPa message.

[0182] For example, if the first device includes gNB-CU and the second device includes gNB-DU, gNB-CU can send the first indication information to gNB-DU via F1AP message.

[0183] The following examples, using several embodiments, illustrate the technical solutions of this disclosure, with the first device including core network equipment and the second device including access network equipment (e.g., a base station).

[0184] In some embodiments, the terminal may transmit uplink reference signals using bandwidth aggregation. For example, the aggregated bandwidth includes two BWPs, namely BWP#1 and BWP#2. The terminal is configured with four SRS resource sets in BWP#1, identified as 1, 2, 3, and 4, meaning that the uplink positioning reference signal resources associated with BWP#1 include resources from SRS resource set1, SRS resource set2, SRS resource set3, and SRS resource set4. The terminal is configured with three SRS resource sets in BWP#2, identified as 1, 2, and 3, meaning that the uplink positioning reference signal resources associated with BWP#1 include resources from SRS resource set1, SRS resource set2, and SRS resource set3.

[0185] For example, a network device can instruct a terminal to perform bandwidth aggregation on uplink reference signal resources associated with different bandwidths, and the terminal can subsequently use the aggregated resources to transmit uplink reference signals simultaneously. For instance, the network device can instruct the terminal to perform bandwidth aggregation on SRS resource set 1 of BWP#1 and SRS resource set 1 of BWP#2, and the terminal can use SRS resource set 1 of BWP#1 and SRS resource set 1 of BWP#2 simultaneously to transmit SRS.

[0186] When a core network device needs to deactivate the SRS resource set identified as 2 in BWP#1, it can send a first indication message to the base station. This first indication message instructs the base station to deactivate the SRS resource set identified as 2 in BWP#1. Based on the first indication message, the base station can accurately determine whether the SRS resource set identified as 2 in BWP#1 needs to be deactivated.

[0187] In some embodiments, the base station may further send a second indication information to the terminal, the second indication information being used to instruct the terminal to deactivate the SRS resource set identified by identifier 2 on BWP#1. Based on the second indication information, the terminal can accurately deactivate the SRS resource set identified by identifier 2 on BWP#1, thereby the terminal can stop using the resources in the SRS resource set identified by identifier 2 on BWP#1 to send uplink reference signals (e.g., SRS).

[0188] It should be noted that the granularity of activating or deactivating uplink positioning reference signal resources can be a resource set, such as at least one SRS resource set, or a specific resource within a resource set, such as at least one SRS resource in at least one SRS resource set.

[0189] In some embodiments, the first indication information includes at least one of the following: bandwidth information; uplink reference signal resource information.

[0190] For example, the first indication information sent by the first device to the second device may include bandwidth information and uplink reference signal resource information.

[0191] The first device can determine the first bandwidth associated with the uplink reference signal resource that needs to be activated or deactivated based on the bandwidth information, and determine the first uplink reference signal resource that needs to be activated or deactivated based on the uplink reference signal resource information. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0192] For example, the first instruction information sent by the first device to the second device may include bandwidth information.

[0193] The first device can determine the first bandwidth associated with the uplink reference signal resource that needs to be activated or deactivated based on the bandwidth information. The uplink reference signal resource associated with the first bandwidth that needs to be activated or deactivated can be determined based on the uplink reference signal resource information indicated by other devices besides the first device, or based on the uplink reference signal resource information agreed upon in the protocol. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0194] For example, the first instruction information sent by the first device to the second device may include uplink reference signal resource information.

[0195] The first device can determine the first uplink reference signal resource that needs to be activated or deactivated based on the uplink reference signal resource information. The first bandwidth associated with the first uplink reference signal resource that needs to be activated or deactivated can be determined based on the bandwidth information indicated by other devices besides the first device, or based on the bandwidth information agreed upon in the protocol. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0196] In some embodiments, bandwidth information includes at least one of the following:

[0197] Frequency band identifiers, such as New Radio (NR) frequency band identifiers, can be called FreqBandIndicatorNR;

[0198] Bandwidth information, such as BWP ID, or BWP location and bandwidth, can be used to determine the specific BWP based on its location (e.g., frequency domain location) and bandwidth.

[0199] The common reference point of resource block grids, also known as Point A;

[0200] The absolute frequency position of the reference resource block can be called the absolute frequency PointA;

[0201] Offset relative to the reference point;

[0202] Carrier bandwidth;

[0203] Community signage.

[0204] In some embodiments, the second device may determine at least one frequency band based on the frequency band identifier and use the determined frequency band as the first bandwidth.

[0205] In some embodiments, the second device may determine at least one BWP based on bandwidth portion information and use the determined BWP as the first bandwidth.

[0206] In some embodiments, the second device may determine frequency domain resources (e.g., at least one resource block, at least one resource block grid) based on a common reference point of the resource block grid, and use the determined frequency domain resources as a first bandwidth. For example, the second device may determine the frequency domain resources based on a common reference point of the resource block grid, specifically by determining the starting position of the frequency domain resources based on the common reference point of the resource block grid and the offset relative to the reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0207] In some embodiments, the second device may determine frequency domain resources (e.g., at least one resource block and at least one reference resource block) based on the absolute frequency position of a reference resource block, and use the determined frequency domain resources as a first bandwidth. For example, the second device may determine the frequency domain resources based on the absolute frequency position of the reference resource block, specifically by determining the starting position of the frequency domain resources based on the absolute frequency position of the reference resource block and its offset relative to a reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0208] In some embodiments, a network device can configure associated frequency domain resources for a cell. A second device can determine the cell based on the cell identifier and determine the associated frequency domain resources, thereby determining the associated frequency domain resources as the first bandwidth. For example, a network device can configure at least one BWP for a cell. After determining the cell based on the cell identifier, the second device can determine at least one BWP associated with the cell and then determine the at least one BWP associated with the cell as the first bandwidth.

[0209] In some embodiments, the uplink reference signal resource information includes at least one of the following:

[0210] The identifier of the uplink reference signal resource set, such as the SRS resource set ID;

[0211] The identifier of the uplink reference signal resource, such as the SRS resource ID;

[0212] The identifier for uplink reference signal resource triggering, such as SRS resource trigger ID.

[0213] In some embodiments, the uplink reference signal resource information may include an identifier of an uplink reference signal resource set. The second device may determine the uplink reference signal resource set based on the identifier of the uplink reference signal resource set, and then determine that the uplink reference signal resources associated with the first bandwidth that need to be activated or deactivated include the determined uplink reference signal resource set.

[0214] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource. The second device may determine the uplink reference signal resource based on the identifier of the uplink reference signal resource, and then determine that the uplink reference signal resource associated with the first bandwidth that needs to be activated or deactivated includes the determined uplink reference signal resource.

[0215] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource set and the identifier of the uplink reference signal resource. The second device can determine the uplink reference signal resource set in which the uplink reference signal resource that needs to be activated or deactivated is located based on the identifier of the uplink reference signal resource set, and then determine the uplink reference signal resource that needs to be activated or deactivated in the uplink reference signal resource set based on the identifier of the uplink reference signal resource.

[0216] In some embodiments, the uplink reference signal transmitted based on bandwidth aggregation includes at least one of the following:

[0217] Semi-persistent upward reference signal, aperiodic upward reference signal.

[0218] In some embodiments, resources used for transmitting semi-persistent uplink reference signals can be activated or deactivated. For resources used for transmitting aperiodic uplink reference signals, the duration can be indicated, so activation is sufficient. After activation, aperiodic uplink reference signals are transmitted only during the duration, and transmission can cease at the end of the duration, thus deactivation is unnecessary.

[0219] Of course, in some embodiments, resources used for transmitting aperiodic uplink reference signals may also be deactivated; however, the embodiments disclosed herein are mainly described in the case where resources used for transmitting aperiodic uplink reference signals do not need to be deactivated.

[0220] In some embodiments, after receiving the first indication information, the second device may further send a second indication information to the terminal, instructing the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth. The second bandwidth may be the same as the first bandwidth, or it may be a bandwidth within the first bandwidth.

[0221] For example, the first indication information instructs the first node to activate the first uplink reference signal resource associated with the terminal in the first bandwidth, and the second indication information sent by the second device to the terminal can be used to instruct the terminal to activate the first uplink reference signal resource associated with the second bandwidth; for example, the first indication information instructs the first node to deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth, and the second indication information sent by the second device to the terminal can be used to instruct the terminal to deactivate the first uplink reference signal resource associated with the second bandwidth.

[0222] For example, when the uplink reference signal includes a semi-persistent uplink reference signal, the second device can send second indication information to the terminal via a Media Access Control Element (MAC CE). The second indication information may include at least one of the following: an identifier of the uplink reference signal resource set, such as an SRS resource set ID; or an identifier of the uplink reference signal resource, such as an SRS resource ID.

[0223] For example, when the uplink reference signal includes an aperiodic uplink reference signal, the second device can send the second indication information to the terminal via downlink control information (DCI), wherein the second indication information may include an uplink reference signal resource trigger (SRS resource trigger).

[0224] In some embodiments, the uplink reference signal resource information may include identifiers of uplink reference signal resource triggers. For example, the uplink reference signal resource information may include an uplink reference signal resource trigger list, which includes at least one identifier of an uplink reference signal resource trigger. For instance, if the uplink reference signal includes SRS, the list may be an aperiodic SRS-ResourceTriggerList.

[0225] The second device can determine the identifier of the uplink reference signal resource triggering according to the first instruction information, and then send the identifier of the uplink reference signal resource triggering to the terminal through the second instruction information. There is an association between the identifier of the uplink reference signal resource triggering and the uplink reference signal resource. The terminal can determine the uplink reference signal resource associated with the received identifier of the uplink reference signal resource triggering according to the association, and then activate the uplink reference signal resource.

[0226] In some embodiments, the first bandwidth is one bandwidth or multiple bandwidths.

[0227] In some embodiments, the first uplink reference signal resource is one uplink reference signal resource or multiple uplink reference signal resources.

[0228] In some embodiments, when the terminal transmits uplink reference signals using bandwidth aggregation, resources for transmitting uplink reference signals can be configured separately on each aggregated bandwidth.

[0229] For example, the first bandwidth indicated by the first indication information can be a bandwidth, and the first uplink reference signal resource indicated can be an uplink reference signal resource. Then the first indication information can indicate whether to activate or deactivate an uplink reference signal resource associated with this bandwidth.

[0230] However, since the terminal uses bandwidth aggregation to send uplink reference signals, that is, the terminal can send uplink reference signals on multiple uplink reference signal resources associated with multiple bandwidths. If the first indication information only indicates to activate or deactivate one uplink reference signal resource associated with one bandwidth, the flexibility of the indication is relatively limited.

[0231] Therefore, in some embodiments, the first bandwidth can be multiple bandwidths, and the first uplink reference signal resource can be multiple uplink reference signal resources. In this case, the first indication information can instruct the activation or deactivation of the multiple uplink reference signal resources associated with these multiple bandwidths. This improves the flexibility of the activation and deactivation instructions.

[0232] For example, the aggregated bandwidth includes two BWPs, namely BWP#1 and BWP#2. The network device configures four SRS resource sets for the terminal in BWP#1, identified as 1, 2, 3 and 4 respectively, and configures three SRS resource sets for the terminal in BWP#2, identified as 1, 2 and 3 respectively.

[0233] The first bandwidth indicated by the first indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 2 and 3 associated with BWP#2. The second device can then determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 2 and 3 associated with BWP#2. Accordingly, activation or deactivation of multiple uplink reference signal resources associated with multiple bandwidths can be achieved, improving the flexibility of activation / deactivation indication operations.

[0234] In some embodiments, the first indication information may further include the association between the first uplink reference signal resource and the first bandwidth, or it may not include the association between the first uplink reference signal resource and the first bandwidth.

[0235] In some embodiments, when the first bandwidth is multiple bandwidths, if the multiple uplink reference signal resources indicated by the first indication information are identified differently among the uplink reference signal resources associated with the multiple bandwidths, then the first indication information may include the association between the first uplink reference signal resources and the first bandwidth.

[0236] For example, in the case described in the above embodiments, the first indication information may include an association relationship, which is used to indicate that the SRS resource sets identified as 1 and 2 are associated with BWP#1, and the SRS resource sets identified as 2 and 3 are associated with BWP#2, so that the second device can accurately determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1 and the SRS resource sets identified as 2 and 3 associated with BWP#2.

[0237] In some embodiments, when the first bandwidth is multiple bandwidths, if the first uplink reference signal resource indicated by the first indication information is identified as the same in each bandwidth-associated uplink reference signal resource, then the first indication information may not need to include the association between the first uplink reference signal resource and the first bandwidth.

[0238] For example, the first bandwidth indicated by the first indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 1 and 2 associated with BWP#2. Therefore, the first indication information may not necessarily include the association relationship, and the second device can determine that the SRS resource sets identified as 1 and 2 refer to the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 1 and 2 associated with BWP#2.

[0239] Figure 4 This is a schematic flowchart illustrating an activation control method according to an embodiment of the present disclosure. The activation control method shown in this embodiment can be executed by a second device, which can communicate with the first device.

[0240] like Figure 4 As shown, the activation control method may include the following steps:

[0241] In step S401, a first indication message sent by the first device is received, wherein the first indication message is used to instruct the second device to activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth.

[0242] It should be noted that, Figure 4 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0243] In some embodiments, when the first device instructs the second device to activate or deactivate the first uplink reference signal resource of the terminal, it may send first indication information to the second device. The second device can determine, based on the first indication information, that it is necessary to activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth. The first uplink reference signal resource includes resources used by the terminal to transmit uplink reference signals.

[0244] Since the first instruction information does not merely instruct the second device to activate or deactivate a certain uplink reference signal resource of the terminal, but rather instructs the second device to activate or deactivate the first uplink reference signal resource associated with the first bandwidth, it is easier for the second device to accurately determine which uplink reference signal resource associated with the first bandwidth to activate or deactivate. This helps to avoid the difficulty in accurately determining which uplink reference signal resource needs to be activated or deactivated when the terminal uses bandwidth aggregation to send uplink reference signals.

[0245] In some embodiments, the first device includes a core network device and the second device includes an access network device; or, the first device includes a central unit access network device and the second device includes a distributed unit access network device.

[0246] For example, the core network device can send a first indication message to the access network device, which can then activate or deactivate the first uplink reference signal resource associated with the terminal in the first bandwidth according to the first indication. In some embodiments, the core network device includes, but is not limited to, a Location Management Function (LMF) and an Access Control Function (AMF).

[0247] For example, in a separate radio access network architecture, the gNB-CU can send a first indication message to the gNB-DU, and the gNB-DU can activate or deactivate the first uplink reference signal resource associated with the first bandwidth of the terminal according to the first indication. In some embodiments, the gNB-CU can receive the first indication message from the core network equipment.

[0248] The first indication information is carried in at least one of the following: New Radio Positioning Protocol A (NRPPa) message; F1AP message.

[0249] For example, if the first device includes a core network device and the second device includes an access network device, the core network device can send the first indication information to the access network device via an NRPPa message.

[0250] For example, if the first device includes gNB-CU and the second device includes gNB-DU, gNB-CU can send the first indication information to gNB-DU via F1AP message.

[0251] In some embodiments, the terminal may transmit uplink reference signals using bandwidth aggregation. For example, the aggregated bandwidth includes two BWPs, namely BWP#1 and BWP#2. The terminal is configured with four SRS resource sets in BWP#1, identified as 1, 2, 3, and 4, meaning that the uplink positioning reference signal resources associated with BWP#1 include resources from SRS resource set1, SRS resource set2, SRS resource set3, and SRS resource set4. The terminal is configured with three SRS resource sets in BWP#2, identified as 1, 2, and 3, meaning that the uplink positioning reference signal resources associated with BWP#1 include resources from SRS resource set1, SRS resource set2, and SRS resource set3.

[0252] For example, a network device can instruct a terminal to perform bandwidth aggregation on uplink reference signal resources associated with different bandwidths, and the terminal can subsequently use the aggregated resources to transmit uplink reference signals simultaneously. The network device can instruct the terminal to perform bandwidth aggregation on SRS resource set 1 of BWP#1 and SRS resource set 1 of BWP#2, and the terminal can use both SRS resource set 1 of BWP#1 and SRS resource set 1 of BWP#2 to transmit SRS simultaneously.

[0253] When a core network device needs to deactivate the SRS resource set identified as 2 in BWP#1, it can send a first indication message to the base station. This first indication message instructs the base station to deactivate the SRS resource set identified as 2 in BWP#1. Based on the first indication message, the base station can accurately determine whether the SRS resource set identified as 2 in BWP#1 needs to be deactivated.

[0254] In some embodiments, the first indication information includes at least one of the following: bandwidth information; uplink reference signal resource information.

[0255] For example, the first indication information sent by the first device to the second device may include bandwidth information and uplink reference signal resource information.

[0256] The first device can determine the first bandwidth associated with the uplink reference signal resource that needs to be activated or deactivated based on the bandwidth information, and determine the first uplink reference signal resource that needs to be activated or deactivated based on the uplink reference signal resource information. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0257] For example, the first instruction information sent by the first device to the second device may include bandwidth information.

[0258] The first device can determine the first bandwidth associated with the uplink reference signal resource that needs to be activated or deactivated based on the bandwidth information. The uplink reference signal resource associated with the first bandwidth that needs to be activated or deactivated can be determined based on the uplink reference signal resource information indicated by other devices besides the first device, or based on the uplink reference signal resource information agreed upon in the protocol. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0259] For example, the first instruction information sent by the first device to the second device may include uplink reference signal resource information.

[0260] The first device can determine the first uplink reference signal resource that needs to be activated or deactivated based on the uplink reference signal resource information. The first bandwidth associated with the first uplink reference signal resource that needs to be activated or deactivated can be determined based on the bandwidth information indicated by other devices besides the first device, or based on the bandwidth information agreed upon in the protocol. Thus, based on the bandwidth information and the uplink reference signal resource information, it can accurately determine whether the first uplink reference signal resource associated with the terminal in the first bandwidth needs to be activated or deactivated.

[0261] In some embodiments, bandwidth information includes at least one of the following:

[0262] Frequency band identifiers, such as New Radio (NR) frequency band identifiers, can be called FreqBandIndicatorNR;

[0263] Bandwidth information, such as BWP ID, or BWP location and bandwidth, can be used to determine the specific BWP based on its location (e.g., frequency domain location) and bandwidth.

[0264] The common reference point of the resource block grid can also be called Point A;

[0265] The absolute frequency position of the reference resource block can be called the absolute frequency PointA;

[0266] Offset relative to the reference point;

[0267] Carrier bandwidth;

[0268] Community signage.

[0269] In some embodiments, the second device may determine at least one frequency band based on the frequency band identifier and use the determined frequency band as the first bandwidth.

[0270] In some embodiments, the second device may determine at least one BWP based on bandwidth portion information and use the determined BWP as the first bandwidth.

[0271] In some embodiments, the second device may determine frequency domain resources (e.g., at least one resource block, at least one resource block grid) based on a common reference point of resource block grids, and use the determined frequency domain resources as a first bandwidth. For example, the second device may determine the frequency domain resources based on a common reference point of the resource block grids, specifically by determining the starting position of the frequency domain resources based on the common reference point of the resource block grids and the offset relative to the reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0272] In some embodiments, the second device may determine frequency domain resources (e.g., at least one resource block and at least one reference resource block) based on the absolute frequency position of a reference resource block, and use the determined frequency domain resources as a first bandwidth. For example, the second device may determine the frequency domain resources based on the absolute frequency position of the reference resource block, specifically by determining the starting position of the frequency domain resources based on the absolute frequency position of the reference resource block and its offset relative to a reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0273] In some embodiments, a network device can configure associated frequency domain resources for a cell, and a second device can determine the cell based on the cell identifier and determine the associated frequency domain resources, thereby determining the associated frequency domain resources as the first bandwidth. For example, the network device can configure at least one BWP for a cell, and after the second device determines the cell based on the cell identifier, it can determine at least one BWP associated with the cell, thereby determining the at least one BWP associated with the cell as the first bandwidth.

[0274] In some embodiments, the uplink reference signal resource information includes at least one of the following:

[0275] The identifier of the uplink reference signal resource set, such as the SRS resource set ID;

[0276] The identifier of the uplink reference signal resource, such as the SRS resource ID;

[0277] The identifier for uplink reference signal resource triggering, such as SRS resource trigger ID.

[0278] In some embodiments, the uplink reference signal resource information may include an identifier of an uplink reference signal resource set. The second device may determine the uplink reference signal resource set based on the identifier of the uplink reference signal resource set, and then determine that the uplink reference signal resources associated with the first bandwidth that need to be activated or deactivated include the determined uplink reference signal resource set.

[0279] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource. The second device may determine the uplink reference signal resource based on the identifier of the uplink reference signal resource, and then determine that the uplink reference signal resource associated with the first bandwidth that needs to be activated or deactivated includes the determined uplink reference signal resource.

[0280] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource set and the identifier of the uplink reference signal resource. The second device can determine the uplink reference signal resource set in which the uplink reference signal resource that needs to be activated or deactivated is located based on the identifier of the uplink reference signal resource set, and then determine the uplink reference signal resource that needs to be activated or deactivated in the uplink reference signal resource set based on the identifier of the uplink reference signal resource.

[0281] In some embodiments, the uplink reference signal transmitted based on bandwidth aggregation includes at least one of the following:

[0282] Semi-persistent upward reference signal, aperiodic upward reference signal.

[0283] In some embodiments, resources used for transmitting semi-persistent uplink reference signals can be activated or deactivated. For resources used for transmitting aperiodic uplink reference signals, the duration can be indicated, so activation is sufficient. After activation, aperiodic uplink reference signals are transmitted only during the duration, and transmission can cease at the end of the duration, thus deactivation is unnecessary.

[0284] Of course, in some embodiments, resources used for transmitting aperiodic uplink reference signals may also be deactivated; however, the embodiments disclosed herein are mainly described in the case where resources used for transmitting aperiodic uplink reference signals do not need to be deactivated.

[0285] In some embodiments, after receiving the first indication information, the second device may further send a second indication information to the terminal, instructing the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth.

[0286] In some embodiments, the second indication information is carried in at least one of the following: a media access control layer control element; downlink control information.

[0287] For example, when the uplink reference signal includes a semi-persistent uplink reference signal, the second device can send second indication information to the terminal via a Media Access Control Layer Control Element (MAC CE). The second indication information may include at least one of the following: an identifier of the uplink reference signal resource set, such as an SRS resource set ID; or an identifier of the uplink reference signal resource, such as an SRS resource ID.

[0288] For example, when the uplink reference signal includes an aperiodic uplink reference signal, the second device can send the second indication information to the terminal via downlink control information (DCI), wherein the second indication information may include an uplink reference signal resource trigger (SRS resource trigger).

[0289] In some embodiments, the uplink reference signal resource information may include identifiers of uplink reference signal resource triggers. For example, the uplink reference signal resource information may include an uplink reference signal resource trigger list, which includes at least one identifier of an uplink reference signal resource trigger. For instance, if the uplink reference signal includes SRS, the list may be an aperiodic SRS-ResourceTriggerList.

[0290] The second device can determine the identifier of the uplink reference signal resource triggering according to the first instruction information, and then send the identifier of the uplink reference signal resource triggering to the terminal through the second instruction information. There is an association between the identifier of the uplink reference signal resource triggering and the uplink reference signal resource. The terminal can determine the uplink reference signal resource associated with the received identifier of the uplink reference signal resource triggering according to the association, and then activate the uplink reference signal resource.

[0291] In some embodiments, the first bandwidth is one bandwidth or multiple bandwidths.

[0292] In some embodiments, the first uplink reference signal resource is one uplink reference signal resource or multiple uplink reference signal resources.

[0293] In some embodiments, when the terminal transmits uplink reference signals using bandwidth aggregation, resources for transmitting uplink reference signals can be configured separately on each aggregated bandwidth.

[0294] For example, the first bandwidth indicated by the first indication information can be a bandwidth, and the first uplink reference signal resource indicated can be an uplink reference signal resource. Then the first indication information can indicate whether to activate or deactivate an uplink reference signal resource associated with this bandwidth.

[0295] However, since the terminal uses bandwidth aggregation to send uplink reference signals, that is, the terminal can send uplink reference signals on multiple uplink reference signal resources associated with multiple bandwidths. If the first indication information only indicates to activate or deactivate one uplink reference signal resource associated with one bandwidth, the flexibility of the indication is relatively limited.

[0296] Therefore, in some embodiments, the first bandwidth can be multiple bandwidths, and the first uplink reference signal resource can be multiple uplink reference signal resources. In this case, the first indication information can instruct the activation or deactivation of the multiple uplink reference signal resources associated with these multiple bandwidths. This improves the flexibility of the activation and deactivation instructions.

[0297] For example, the aggregated bandwidth includes two BWPs, namely BWP#1 and BWP#2. The network device configures four SRS resource sets for the terminal in BWP#1, identified as 1, 2, 3 and 4 respectively, and configures three SRS resource sets for the terminal in BWP#2, identified as 1, 2 and 3 respectively.

[0298] The first bandwidth indicated by the first indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 2 and 3 associated with BWP#2. The second device can then determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 2 and 3 associated with BWP#2. Accordingly, activation or deactivation of multiple uplink reference signal resources associated with multiple bandwidths can be achieved, improving the flexibility of activation / deactivation indication operations.

[0299] In some embodiments, the first indication information may further include the association between the first uplink reference signal resource and the first bandwidth, or it may not include the association between the first uplink reference signal resource and the first bandwidth.

[0300] In some embodiments, when the first bandwidth is multiple bandwidths, if the multiple uplink reference signal resources indicated by the first indication information are identified differently among the uplink reference signal resources associated with the multiple bandwidths, then the first indication information may include the association between the first uplink reference signal resources and the first bandwidth.

[0301] For example, in the case described in the above embodiments, the first indication information may include an association relationship, which is used to indicate that the SRS resource sets identified as 1 and 2 are associated with BWP#1, and the SRS resource sets identified as 2 and 3 are associated with BWP#2, so that the second device can accurately determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1 and the SRS resource sets identified as 2 and 3 associated with BWP#2.

[0302] In some embodiments, when the first bandwidth is multiple bandwidths, if the first uplink reference signal resource indicated by the first indication information is identified as the same in each bandwidth-associated uplink reference signal resource, then the first indication information may not need to include the association between the first uplink reference signal resource and the first bandwidth.

[0303] For example, the first bandwidth indicated by the first indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 1 and 2 associated with BWP#2. Therefore, the first indication information may not necessarily include the association relationship, and the second device can determine that the SRS resource sets identified as 1 and 2 refer to the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 1 and 2 associated with BWP#2.

[0304] Figure 5 This is a schematic flowchart illustrating another activation control method according to an embodiment of the present disclosure. The activation control method shown in this embodiment can be executed by a second device. Figure 5 As shown, the activation control method also includes:

[0305] In step S501, a second indication message is sent to the terminal, wherein the second indication message is used to instruct the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth. The second bandwidth may be the same as the first bandwidth, or the second bandwidth may be a bandwidth within the first bandwidth.

[0306] It should be noted that, Figure 5 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0307] In some embodiments, after the base station determines, based on the first indication information, whether to activate or deactivate the first uplink reference signal resource associated with the first bandwidth of the terminal, it can determine the second bandwidth, wherein the second bandwidth may be the same as the first bandwidth, or the second bandwidth may be a bandwidth within the first bandwidth.

[0308] Furthermore, the base station can send a second indication message to the terminal, instructing the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth. Upon receiving the second indication message, the terminal can determine whether to activate or deactivate the first uplink reference signal resource associated with the second bandwidth. For example, if the second indication message instructs the terminal to activate the first uplink reference signal resource associated with the second bandwidth, the terminal can activate or deactivate it accordingly.

[0309] For example, the second instruction information is used to instruct the terminal to deactivate the SRS resource set identified by identifier 2 on BWP#1. Based on the second instruction information, the terminal can accurately deactivate the SRS resource set identified by identifier 2 on BWP#1, and thus the terminal can stop using the resources in the SRS resource set identified by identifier 2 on BWP#1 to send uplink reference signals (e.g., SRS).

[0310] For example, the second indication information is used to instruct the terminal to simultaneously activate or deactivate the SRS resource set identified by identifier 2 on BWP#1 and the SRS resource set identified by identifier 2 on BWP#2. Based on the second indication information, the terminal can accurately deactivate the SRS resource set identified by identifier 2 on BWP#1 and the SRS resource set identified by identifier 2 on BWP#2, thereby stopping the terminal from using the resources in the SRS resource set identified by identifier 2 on BWP#1 and the SRS resource set identified by identifier 2 on BWP#2 to transmit uplink reference signals (e.g., SRS). Exemplarily, the second indication information can be carried in the MAC CE, and the second device is a base station. Then, the base station can activate or deactivate the uplink reference signals of multiple BWPs (e.g., BWP#1 and BWP#2) through a single MAC CE.

[0311] It should be noted that the granularity of activating or deactivating uplink positioning reference signal resources can be a resource set, such as at least one SRS resource set, or a specific resource within a resource set, such as at least one SRS resource in at least one SRS resource set.

[0312] In some embodiments, the second indication information includes at least one of the following:

[0313] Community signage;

[0314] Bandwidth information;

[0315] Uplink reference signal resource information;

[0316] Indicator of spatial relation.

[0317] In some embodiments, the second indication information may include at least one cell identifier. After receiving the second indication information, the terminal can configure associated frequency domain resources for the cell, determine at least one cell based on the at least one cell identifier in the second indication information, determine the frequency domain resources associated with each of the at least one cell, and then determine the frequency domain resources associated with the cell as the second bandwidth.

[0318] For example, when the second indication information contains only one cell identifier, the second bandwidth associated with the cell corresponding to that cell identifier can be at least two bandwidths, such as at least two BWPs, at least two frequency point identifiers, at least two point As, and corresponding offset values ​​relative to point A. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information.

[0319] For example, when the second indication information contains multiple cell identifiers, the second bandwidth associated with each cell identifier can be at least one bandwidth. Taking multiple cell identifiers including Cell ID1 and Cell ID2 as an example, cell ID1 is associated with BWP1, and cell ID2 is associated with BWP2. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information.

[0320] In some embodiments, the second indication information may include at least two bandwidth information items. After receiving the second indication information, the terminal can determine the bandwidth associated with the uplink positioning reference signal based on the at least two bandwidth information items in the second indication information. For example, the second indication information may include at least two BWP information items, or at least two cell identification information items, or at least two frequency band identification information items. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information item.

[0321] In some embodiments, the second indication information may include at least two uplink reference signal resource information, such as two SRS resource sets, with each SRS resource set associated with a bandwidth. After receiving the second indication information, the terminal can determine which uplink positioning reference signal needs to be activated or deactivated based on the uplink reference signal resource information and its associated bandwidth in the second indication information.

[0322] For example, after determining, based on the first indication information, that the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2, need to be activated, the base station can determine the second bandwidth. For example, the second bandwidth may be the same as the first bandwidth, also including BWP#1 and BWP#2. The base station can send the second indication information to the terminal to instruct the terminal to activate the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2. Based on the second indication information, the terminal can activate the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2.

[0323] In some embodiments, the second indication information may include only one spatial relationship indication, or may include multiple spatial relationship indications. The spatial relationship indication is used to indicate spatial relationships.

[0324] For example, if the second indication information includes a spatial relationship indication, the terminal can communicate based on the spatial relationship indicated by the spatial relationship indication on each bandwidth indicated by the second indication.

[0325] For example, if the second indication information includes multiple spatial relationship indications, each bandwidth corresponds to one spatial relationship indication, and the terminal can determine the spatial relationship corresponding to each indicated bandwidth based on the second indication.

[0326] In some embodiments, bandwidth information includes at least one of the following:

[0327] Frequency band identifiers, such as New Radio frequency band identifiers, can be called FreqBandIndicatorNR;

[0328] Bandwidth information, such as BWP ID, or the location and bandwidth of the BWP, can be used to determine the specific BWP based on its location (e.g., frequency domain location) and bandwidth.

[0329] The common reference point of the resource block grid can also be called Point A;

[0330] The absolute frequency position of the reference resource block can be called the absolute frequency PointA;

[0331] Offset relative to the reference point;

[0332] Carrier bandwidth;

[0333] Community signage.

[0334] In some embodiments, the terminal may determine at least one frequency band based on the frequency band identifier and use the determined frequency band as the second bandwidth.

[0335] In some embodiments, the terminal may determine at least one BWP based on bandwidth portion information and use the determined BWP as the second bandwidth.

[0336] In some embodiments, the terminal may determine frequency domain resources (e.g., at least one resource block, at least one resource block grid) based on a common reference point of the resource block grid, and use the determined frequency domain resources as a second bandwidth. For example, the terminal may determine the frequency domain resources based on the common reference point of the resource block grid, specifically by determining the starting position of the frequency domain resources based on the common reference point of the resource block grid and the offset relative to the reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0337] In some embodiments, the terminal may determine frequency domain resources (e.g., at least one resource block and at least one reference resource block) based on the absolute frequency position of a reference resource block, and use the determined frequency domain resources as a second bandwidth. For example, the terminal may determine the frequency domain resources based on the absolute frequency position of the reference resource block, specifically by determining the starting position of the frequency domain resources based on the absolute frequency position of the reference resource block and its offset relative to a reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0338] In some embodiments, the network device can configure associated frequency domain resources for a cell. The terminal can determine the cell based on the cell identifier and determine the associated frequency domain resources, thereby determining the associated frequency domain resources as the first bandwidth. For example, the network device can configure at least one BWP for a cell. After the terminal determines the cell based on the cell identifier, it can determine at least one BWP associated with the cell and then determine the at least one BWP associated with the cell as the second bandwidth.

[0339] Figure 6 This is a schematic flowchart illustrating an activation control method according to an embodiment of the present disclosure. The activation control method shown in this embodiment can be executed by a terminal, which can communicate with a second device.

[0340] like Figure 6 As shown, the activation control method may include the following steps:

[0341] In step S601, a second indication information sent by the second device is received, wherein the second indication information is used to instruct the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth;

[0342] In step S602, the first uplink reference signal resource associated with the second bandwidth is activated or deactivated.

[0343] It should be noted that, Figure 6 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0344] In some embodiments, after the second device determines, based on the first indication information, whether to activate or deactivate the first uplink reference signal resource associated with the first bandwidth of the terminal, it can determine the second bandwidth. The second bandwidth may be the same as the first bandwidth, or it may be a bandwidth within the first bandwidth. For example, the first bandwidth is a bandwidth determined according to a frequency band identifier, and the second bandwidth may be one or more BWPs within the bandwidth determined according to the frequency band identifier.

[0345] Furthermore, the second device can send a second instruction to the terminal, which instructs the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth. Based on the second instruction, the terminal can determine whether to activate or deactivate the first uplink reference signal resource associated with the second bandwidth, and thus activate or deactivate the first uplink reference signal resource associated with the second bandwidth.

[0346] Since the second instruction information does not merely instruct the terminal to activate or deactivate a certain uplink reference signal resource, but rather instructs the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth, it facilitates the terminal to accurately determine which uplink reference signal resource associated with the first bandwidth to activate or deactivate. This helps to avoid the difficulty in accurately determining which uplink reference signal resource needs to be activated or deactivated when the terminal uses bandwidth aggregation to send uplink reference signals.

[0347] In some embodiments, the second indication information includes at least one of the following:

[0348] Community signage;

[0349] Bandwidth information;

[0350] Uplink reference signal resource information;

[0351] Spatial relationship indication.

[0352] In some embodiments, the second indication information may include at least one cell identifier. The network device may configure associated frequency domain resources for the cell. After receiving the second indication information, the terminal may determine at least one cell based on the at least one cell identifier in the second indication information, and determine the frequency domain resources associated with each cell in the at least one cell, thereby determining the frequency domain resources associated with the cell as the second bandwidth.

[0353] For example, when the second indication information contains only one cell identifier, the second bandwidth associated with the cell corresponding to that cell identifier can be at least two bandwidths, such as at least two BWPs, at least two frequency point identifiers, at least two point As, and corresponding offset values ​​relative to point A. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information.

[0354] For example, when the second indication information contains multiple cell identifiers, the second bandwidth associated with each cell identifier can be at least one bandwidth. Taking multiple cell identifiers including Cell ID1 and Cell ID2 as an example, cell ID1 is associated with BWP1, and cell ID2 is associated with BWP2. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information.

[0355] In some embodiments, the second indication information may include at least two bandwidth information items. After receiving the second indication information, the terminal can determine the bandwidth associated with the uplink positioning reference signal based on the at least two bandwidth information items in the second indication information. For example, the second indication information may include at least two BWP information items, or at least two cell identification information items, or at least two frequency band identification information items. Accordingly, it is possible to activate or deactivate uplink reference signals of multiple bandwidths using a single second indication information item.

[0356] In some embodiments, the second indication information may include at least two uplink reference signal resource information, such as two SRS resource sets, with each SRS resource set associated with a bandwidth. After receiving the second indication information, the terminal can determine which uplink positioning reference signal needs to be activated or deactivated based on the uplink reference signal resource information and its associated bandwidth in the second indication information.

[0357] For example, after determining, based on the first indication information, that the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2, need to be activated, the base station can determine the second bandwidth. For example, the second bandwidth may be the same as the first bandwidth, also including BWP#1 and BWP#2. The base station can send the second indication information to the terminal to instruct the terminal to activate the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2. Based on the second indication information, the terminal can activate the SRS resource sets associated with BWP#1 and identified as 1 and 2, and the SRS resource sets associated with BWP#2 and identified as 1 and 2.

[0358] In some embodiments, the second indication information may include only one spatial relationship indication, or may include multiple spatial relationship indications. The spatial relationship indication is used to indicate spatial relationships.

[0359] For example, if the second indication information includes a spatial relationship indication, the terminal can communicate based on the spatial relationship indicated by the spatial relationship indication on each bandwidth indicated by the second indication.

[0360] For example, if the second indication information includes multiple spatial relationship indications, each bandwidth corresponds to one spatial relationship indication, and the terminal can determine the spatial relationship corresponding to each indicated bandwidth based on the second indication.

[0361] In some embodiments, the bandwidth information (in the second indication information) includes at least one of the following:

[0362] Frequency band identification;

[0363] Bandwidth information;

[0364] The common reference point of the resource block grid;

[0365] Reference resource block's absolute frequency position;

[0366] Offset relative to the reference point;

[0367] Carrier bandwidth;

[0368] Community signage.

[0369] In some embodiments, the terminal may determine at least one frequency band based on the frequency band identifier and use the determined frequency band as the second bandwidth.

[0370] In some embodiments, the terminal may determine at least one BWP based on bandwidth portion information and use the determined BWP as the second bandwidth.

[0371] In some embodiments, the terminal may determine frequency domain resources (e.g., at least one resource block, at least one resource block grid) based on a common reference point of the resource block grid, and use the determined frequency domain resources as a second bandwidth. For example, the terminal may determine the frequency domain resources based on the common reference point of the resource block grid, specifically by determining the starting position of the frequency domain resources based on the common reference point of the resource block grid and the offset relative to the reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0372] In some embodiments, the terminal may determine frequency domain resources (e.g., at least one resource block and at least one reference resource block) based on the absolute frequency position of a reference resource block, and use the determined frequency domain resources as a second bandwidth. For example, the terminal may determine the frequency domain resources based on the absolute frequency position of the reference resource block, specifically by determining the starting position of the frequency domain resources based on the absolute frequency position of the reference resource block and its offset relative to a reference point, and determining the range of the frequency domain resources based on the carrier bandwidth, thereby determining the frequency domain resources based on the starting position and the range of the frequency domain resources.

[0373] In some embodiments, the network device can configure associated frequency domain resources for a cell. The terminal can determine the cell based on the cell identifier and the associated frequency domain resources, and then determine the associated frequency domain resources as the second bandwidth. For example, the network device can configure at least one BWP for a cell. After determining the cell based on the cell identifier, the terminal can determine at least one BWP associated with the cell, and then determine the at least one BWP associated with the cell as the second bandwidth.

[0374] In some embodiments, the uplink reference signal resource information includes at least one of the following:

[0375] The identifier of the uplink reference signal resource set, such as the SRS resource set ID;

[0376] The identifier of the uplink reference signal resource, such as the SRS resource ID;

[0377] The identifier for uplink reference signal resource triggering, such as SRS resource trigger ID.

[0378] In some embodiments, the uplink reference signal resource information may include an identifier of an uplink reference signal resource set. The terminal can determine the uplink reference signal resource set based on the identifier of the uplink reference signal resource set, and then determine that the uplink reference signal resources associated with the first bandwidth that need to be activated or deactivated include the determined uplink reference signal resource set.

[0379] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource. The terminal can determine the uplink reference signal resource based on the identifier of the uplink reference signal resource, and then determine the uplink reference signal resource that needs to be activated or deactivated in the first bandwidth association, including the determined uplink reference signal resource.

[0380] In some embodiments, the uplink reference signal resource information may include the identifier of the uplink reference signal resource set and the identifier of the uplink reference signal resource. The terminal can determine the uplink reference signal resource set in which the uplink reference signal resource that needs to be activated or deactivated is located based on the identifier of the uplink reference signal resource set, and then determine the uplink reference signal resource that needs to be activated or deactivated in the uplink reference signal resource set based on the identifier of the uplink reference signal resource.

[0381] In some embodiments, the uplink reference signal transmitted based on bandwidth aggregation includes at least one of the following:

[0382] Semi-persistent upward reference signal, aperiodic upward reference signal.

[0383] In some embodiments, resources used for transmitting semi-persistent uplink reference signals can be activated or deactivated. For resources used for transmitting aperiodic uplink reference signals, the duration can be indicated, so activation is sufficient. After activation, aperiodic uplink reference signals are transmitted only during the duration, and transmission can cease at the end of the duration, thus deactivation is unnecessary.

[0384] Of course, in some embodiments, resources used for transmitting aperiodic uplink reference signals may also be deactivated; however, the embodiments disclosed herein are mainly described in the case where resources used for transmitting aperiodic uplink reference signals do not need to be deactivated.

[0385] In some embodiments, after determining, based on the first indication information, to activate or deactivate the first uplink reference signal resource associated with the first bandwidth, the second device may determine a second bandwidth, wherein the second bandwidth may be the same as the first bandwidth, or the second bandwidth may be a bandwidth within the first bandwidth. Further, the second device may further send second indication information to the terminal, instructing the terminal to activate or deactivate the first uplink reference signal resource associated with the second bandwidth.

[0386] For example, when the uplink reference signal includes a semi-persistent uplink reference signal, the second device can send second indication information to the terminal via a Media Access Control Layer Control Element (MAC CE). The second indication information may include at least one of the following: an identifier of the uplink reference signal resource set, such as an SRS resource set ID; or an identifier of the uplink reference signal resource, such as an SRS resource ID.

[0387] For example, when the uplink reference signal includes an aperiodic uplink reference signal, the second device can send the second indication information to the terminal via downlink control information (DCI), wherein the second indication information may include an uplink reference signal resource trigger (SRS resource trigger).

[0388] In some embodiments, the uplink reference signal resource information may include identifiers of uplink reference signal resource triggers. For example, the uplink reference signal resource information may include an uplink reference signal resource trigger list, which includes at least one identifier of an uplink reference signal resource trigger. For instance, if the uplink reference signal includes SRS, the list may be an aperiodic SRS-ResourceTriggerList.

[0389] Based on the second instruction information, the terminal can determine the identifier of the uplink reference signal resource trigger. There is an association between the identifier of the uplink reference signal resource trigger and the uplink reference signal resource. Based on the association, the terminal can determine the uplink reference signal resource associated with the received uplink reference signal resource trigger identifier and then activate the uplink reference signal resource.

[0390] In some embodiments, the second bandwidth is one bandwidth or multiple bandwidths.

[0391] In some embodiments, the first uplink reference signal resource is one uplink reference signal resource or multiple uplink reference signal resources.

[0392] In some embodiments, when the terminal transmits uplink reference signals using bandwidth aggregation, resources for transmitting uplink reference signals can be configured separately on each aggregated bandwidth.

[0393] For example, the second bandwidth indicated by the second indication information can be a bandwidth, and the first uplink reference signal resource indicated can be an uplink reference signal resource. Then the second indication information can indicate whether to activate or deactivate an uplink reference signal resource associated with this bandwidth.

[0394] However, since the terminal uses bandwidth aggregation to send uplink reference signals, that is, the terminal can send uplink reference signals on multiple uplink reference signal resources associated with multiple bandwidths. If the first indication information only indicates to activate or deactivate one uplink reference signal resource associated with one bandwidth, the flexibility of the indication is relatively limited.

[0395] Therefore, in some embodiments, the second bandwidth can be multiple bandwidths, and the first uplink reference signal resource can be multiple uplink reference signal resources. In this case, the second indication information can instruct the activation or deactivation of the multiple uplink reference signal resources associated with these multiple bandwidths. This improves the flexibility of the activation and deactivation instructions.

[0396] For example, the aggregated bandwidth includes two BWPs, namely BWP#1 and BWP#2. The network device configures four SRS resource sets for the terminal in BWP#1, identified as 1, 2, 3 and 4 respectively, and configures three SRS resource sets for the terminal in BWP#2, identified as 1, 2 and 3 respectively.

[0397] The second bandwidth indicated by the second indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 2 and 3 associated with BWP#2. The terminal can then determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 2 and 3 associated with BWP#2. Accordingly, activation or deactivation of multiple uplink reference signal resources associated with multiple bandwidths can be achieved, improving the flexibility of activation / deactivation indication operations.

[0398] In some embodiments, the second indication information may further include the association between the first uplink reference signal resource and the second bandwidth, or it may not include the association between the first uplink reference signal resource and the second bandwidth.

[0399] In some embodiments, when the second bandwidth is multiple bandwidths, if the multiple uplink reference signal resources indicated by the second indication information are identified differently among the uplink reference signal resources associated with the multiple bandwidths, then the second indication information may include the association between the second uplink reference signal resources and the first bandwidth.

[0400] For example, in the case described in the above embodiments, the second indication information may include an association relationship, which is used to indicate that the SRS resource sets identified as 1 and 2 are associated with BWP#1, and the SRS resource sets identified as 2 and 3 are associated with BWP#2, so that the terminal can accurately determine whether to activate or deactivate the SRS resource sets identified as 1 and 2 associated with BWP#1 and the SRS resource sets identified as 2 and 3 associated with BWP#2.

[0401] In some embodiments, when the second bandwidth is multiple bandwidths, if the first uplink reference signal resource indicated by the second indication information is identified as the same in each bandwidth-associated uplink reference signal resource, then the second indication information may not need to include the association between the first uplink reference signal resource and the second bandwidth.

[0402] For example, the first bandwidth indicated by the second indication information may include BWP#1 and BWP#2, and the first uplink reference signal resource indicated may include SRS resource sets identified as 1 and 2 associated with BWP#1, and SRS resource sets identified as 1 and 2 associated with BWP#2. Therefore, the second indication information does not necessarily need to include the association relationship; the terminal can determine that the SRS resource sets identified as 1 and 2 refer to the SRS resource sets identified as 1 and 2 associated with BWP#1, and the SRS resource sets identified as 1 and 2 associated with BWP#2.
