[0181] In some embodiments, the first signal may be a sounding reference signal (SRS).

[0182] In some embodiments, the first signal resource may be a communication resource used to send and / or receive the first signal. The communication resource may be, for example, a time-frequency resource.

[0183] In some embodiments, the first signal resource may be a positioning signal resource, that is, a resource used for sending and / or receiving a positioning signal.

[0184] In some embodiments, the first signal resource may be an SRS resource, that is, a resource used for sending and / or receiving an SRS.

[0185] In some embodiments, the first signal resource may be an SRS resource set.

[0186] In some embodiments, bandwidth aggregation may refer to aggregating multiple contiguous or non-contiguous component carriers (or in other words, carrier units) to obtain a larger transmission bandwidth, thereby obtaining a higher peak rate and throughput, or obtaining higher measurement accuracy (for example, the accuracy of positioning measurements).

[0187] In some embodiments, bandwidth aggregation may refer to carrier aggregation (CA).

[0188] In some embodiments, bandwidth aggregation can support aggregation between the same or different component carriers, including aggregation of component carriers of the same or different bandwidths, adjacent or non-adjacent component carriers within the same frequency band, and component carriers within different frequency bands.

[0189] In some embodiments, "bandwidth-aggregated first signal resources" may refer to bandwidth-aggregated time-frequency resources used to send and / or receive the first signal.

[0190] In some embodiments, the "bandwidth-aggregated first signal resource" may refer to a time-frequency resource obtained by bandwidth aggregation of one or more SRS resource sets.

[0191] In some embodiments, the first information includes at least one of the following:

[0192] 1) a bandwidth aggregation indication, used to instruct the first network device to provide configuration information of the first signal resource of the bandwidth aggregation;

[0193] In some embodiments, the bandwidth aggregation indication may be used to indicate to the serving gNB or gNB-DU that it needs to provide SRS configuration information for bandwidth aggregation.

[0194] In some embodiments, the bandwidth aggregation indication may be defined as a resource type.

[0195] For example, the resource type may include at least one of the following: periodic, semi-persistent, aperiodic, periodic aggregation, semi-persistent aggregation, and aperiodic aggregation.

[0196] 2) Aggregate bandwidth, used to indicate the bandwidth size occupied by the first signal resource of the bandwidth aggregation expected by the second network device;

[0197] In some embodiments, the aggregate bandwidth may be used to indicate a desired aggregate bandwidth size. For example, if the second network device expects an aggregate bandwidth of 100 MHz, the second network device may indicate the value to the first network device through the aggregate bandwidth.

[0198] 3) The number of carriers of the aggregated bandwidth, used to indicate the number of carriers across which the first signal resource of the aggregated bandwidth spans;

[0199] In some embodiments, the number of carriers of the aggregated bandwidth may be used to indicate the number of carriers that the aggregated bandwidth may span, such as 2 or 3.

[0200] 4) The number of resource sets of the aggregated bandwidth, used to indicate the number of first signal resource sets included in the first signal resources of the aggregated bandwidth;

[0201] In some embodiments, the number of resource sets of the aggregated bandwidth may be used to indicate the number of resource sets desired by the second network device.

[0202] In some embodiments, the number of carriers in the aggregated bandwidth may be equal to or different from the number of resource sets in the aggregated bandwidth. In other words, there may be multiple resource sets on one carrier.

[0203] 5) Condition information of the aggregated bandwidth, used to indicate conditions that the first signal resource of the aggregated bandwidth needs to meet.

[0204] In some embodiments, the aggregate bandwidth condition information may be used to indicate the conditions under which the aggregate bandwidth needs to be configured, such as the same periodicity and offset (periodicityAndOffset), slot offset (slotOffset), etc. In other words, the second network device may instruct the first network device to only aggregate carriers with the same slot offset, or in other words, to only select SRS resource sets with the same slot offset for bandwidth aggregation.

[0205] In some embodiments, the aggregated bandwidth condition information may include a parameter indicating that the same value is required, or may include a specific numerical value for the parameter that requires the same value. For example, the aggregated bandwidth condition information may indicate "periodicity" or "same periodicity," indicating that "the resource sets used for bandwidth aggregation should have the same periodicity." For another example, the aggregated bandwidth condition information may indicate "periodicity = 2s," indicating that "the resource sets used for bandwidth aggregation should have a periodicity of 2s."

[0206] Step 2102: The first network device 1021 determines second information.

[0207] In some embodiments, the first network device 1021 may determine the second information based on the first message.

[0208] In some embodiments, the second information is used to indicate a bandwidth-aggregated first signal resource.

[0209] In some embodiments, the second information may be used to indicate bandwidth-aggregated SRS resources.

[0210] In some embodiments, the second information may be used to indicate a bandwidth-aggregated SRS resource set.

[0211] In some embodiments, the name of the second information is not limited, and it can be "SRS resource configuration information", "resource configuration information", "resource information", "resource configuration", etc.

[0212] In some embodiments, "the first network device determines the second information based on the first message" may mean that the first network device configures bandwidth-aggregated first signal resources based on the second network device's indication regarding bandwidth-aggregated first signal resources. In other words, in some embodiments, the first network device may determine, based on the first information, first signal resources that can be bandwidth-aggregated. Optionally, the first network device configures bandwidth-aggregated positioning signal resources based on the second network device's indication regarding bandwidth-aggregated positioning signal resources. Optionally, the first network device configures bandwidth-aggregated SRS resources based on the second network device's indication regarding bandwidth-aggregated SRS resources.

[0213] In some embodiments, the second information may be determined by the first network device according to the first information. In other words, the bandwidth-aggregated SRS resources should meet the requirements of the second network device.

[0214] In some embodiments, the second information may be determined by the first network device based on the first information and its own resources. In other words, the bandwidth-aggregated SRS resources should meet the requirements of the second network device and the resource capabilities of the first network device.

[0215] In some embodiments, the second information includes at least one of the following:

[0216] 1) a first signal resource set identifier, used to indicate a first resource set in a bandwidth-aggregated resource set determined by the first network device based on the first message, wherein the bandwidth-aggregated resource set includes one or more first signal resource sets;

[0217] In some embodiments, the name of the “bandwidth aggregated resource set” is not limited, and it can be an “aggregated resource set”, an “aggregated resource group”, etc.

[0218] In some embodiments, a "bandwidth aggregated resource set" may include one or more resources. In other words, a "bandwidth aggregated resource set" may include one or more resource sets. In other words, a "bandwidth aggregated resource set" may include one or more SRS resource sets.

[0219] In some embodiments, the resource set for bandwidth aggregation determined by the first network device based on the first message may be one or more, wherein the resources (or resource sets) in each resource set have an associated relationship, indicating that the resources (or resource sets) in the resource set can be bandwidth aggregated.

[0220] In some embodiments, the first signal resource set identifier may be an "associated SRS resource set ID." For example, the first network device 1021 determines, based on the configuration of the second network device 1022, that the resource sets capable of bandwidth aggregation include SRS resource set 1, SRS resource set 2, and SRS resource set 3. That is, SRS resource set 1, SRS resource set 2, and SRS resource set 3 are associated resource sets that can be considered for bandwidth aggregation. The "first signal resource set identifier" may be at least one of "1," "2," and "3," wherein the first signal resource identifier "1" corresponds to SRS resource set 1, the first signal resource identifier "2" corresponds to SRS resource set 2, and the first signal resource identifier "3" corresponds to SRS resource set 3. If the first signal resource set identifier is the starting SRS resource set (e.g., SRS resource set 1), the resource configuration information of SRS resource set 2 and SRS resource set 3 may include the first signal resource set identifier, and the identifier is the SRS resource set ID, with a value of 1. The first signal resource set identifier does not exist in the resource configuration of other SRS resource sets (eg, 4). In this way, the terminal and / or the second network device can determine that SRS resource sets 1, 2, and 3 belong to the same bandwidth aggregation resource set through the first signal resource set identifier.

[0221] In some embodiments, the resource sets for bandwidth aggregation determined by the first network device based on the first message may be one or more. In other words, according to the instruction of the second network device, the SRS resource sets that can be aggregated configured by the first network device may be one or more. For example, the first network device determines that the resource sets that can be bandwidth aggregated are SRS resource sets 1, 2, 3, and 4, where SRS resource sets 1 and 2 constitute aggregated resource set 1, and SRS resource sets 3 and 4 constitute aggregated resource set 2.

[0222] 2) A bandwidth aggregated resource identifier, used to identify a bandwidth aggregated resource set determined by the first network device based on the first message, wherein the bandwidth aggregated resource set includes one or more first signal resource sets.

[0223] In some embodiments, the resource identifier for bandwidth aggregation can be a new identifier defined by the first network device for the associated resource set. For example, the first network device 1021 determines, based on the configuration of the second network device 1022, that the resource sets that can be bandwidth aggregated include SRS resource set 1, SRS resource set 2, and SRS resource set 3. That is, SRS resource set 1, SRS resource set 2, and SRS resource set 3 are associated resource sets that can be bandwidth aggregated. Then, the resource configuration information of SRS resource set 1, 2, and 3 can include a "resource identifier for bandwidth aggregation," which has a value of an integer, such as 1. In this way, the terminal and / or the second network device can determine that SRS resource set 1, 2, and 3 belong to the same bandwidth aggregation resource set through the first signal resource set identifier.

[0224] Step 2103 : The first network device 1021 sends a second message to the terminal 101 .

[0225] In some embodiments, the second message is at least one of an RRC message, a DCI (Downlink Control Indication), or a MAC CE.

[0226] In some embodiments, the name of the second message is not limited, and it can be "RRC reconfiguration message", "RRC release message", "resource configuration message", "positioning resource configuration message", etc.

[0227] In some embodiments, the second message may be an SRS configuration message.

[0228] In some embodiments, the second message includes the second information.

[0229] In some embodiments, the name of the second information is not limited, and it can be "SRS configuration information", "bandwidth aggregation SRS configuration information", "aggregation information", "aggregation configuration", "SRS aggregation info", etc.

[0230] In some embodiments, after determining the second information, the first network device 1021 may send the second information to the terminal 101 via a second message.

[0231] For example, for the case where the second information is a "first signal resource set identifier", for example, the first network device 1021 determines, based on the configuration of the second network device 1022, that the resource sets that can be bandwidth aggregated include SRS resource set 1, SRS resource set 2, and SRS resource set 3. Then, when the first network device 1021 sends SRS resource set 2 and SRS resource set 3 to the terminal 101, the first signal resource set identifier "1" corresponding to SRS resource set 1 is included in the configuration information of SRS resource set 2 and SRS resource set 3, indicating that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are considered to be associated resource sets for bandwidth aggregation. If the first signal resource set identifier is the starting SRS resource set (for example, SRS resource set 1), then the resource configuration information of SRS resource set 2 and SRS resource set 3 may include the first signal resource set identifier, and the identifier is SRS resource set ID, and the value is 1. The first signal resource set identifier does not exist in the resource configuration of other SRS resource sets (eg, 4). In this way, the terminal can determine that SRS resource sets 1, 2, and 3 belong to the same bandwidth aggregation resource set through the first signal resource set identifier.

[0232] For example, the associated SRS resource set ID can be included in the SRS resource set configuration, that is, the first signal resource identifier can be included in the second information, associated with the SRS resource set ID in the SRS resource set, and the associated SRS resource set ID is used to indicate the SRS resource set associated with the SRS resource set ID. For example, if the first network device determines that SRS resource set 1 (SRS resource set ID=1), SRS resource set 2 (SRS resource set ID=2), and SRS resource set 3 (SRS resource set ID=3) are considered to be a set of associated SRS resources for bandwidth aggregation, the associated SRS resource set ID is included in the configuration information of SRS resource set 2 and SRS resource set 3, and the associated SRS resource set ID is SRS resource set ID=1 (identified as SRS resource set ID, with a value of 1).

[0233] In other words, the first network device 1021 selects one of the associated SRS resource set(s) as an associated SRS resource set ID, and includes the ID in other associated SRS resource set configurations.

[0234] For example, in the case where the second information is a "resource identifier for bandwidth aggregation," for example, the first network device 1021 determines, based on the configuration of the second network device 1022, that the resource sets capable of bandwidth aggregation include SRS resource set 1, SRS resource set 2, and SRS resource set 3. The resource configuration information of SRS resource sets 1, 2, and 3 may include a "resource identifier for bandwidth aggregation," the value of which is an integer, such as 1. In this way, the terminal can determine, through the first signal resource set identifier, that SRS resource sets 1, 2, and 3 belong to the same bandwidth aggregation resource set. When the first network device 1021 sends SRS resource set 1, SRS resource set 2, and SRS resource set 3 to the terminal 101, the resource identifier of the bandwidth aggregation corresponding to the bandwidth aggregation resource set (the set includes SRS resource set 1, SRS resource set 2, and SRS resource set 3) is included in the configuration information of SRS resource set 1, SRS resource set 2, and SRS resource set 3, indicating that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are associated resource sets for bandwidth aggregation.

[0235] For example, the bandwidth aggregation resource identifier is included in the SRS resource set configuration and corresponds one-to-one with the SRS resource set ID in the SRS resource set, and the associated SRS resource set ID is used to indicate the SRS resource set associated with the SRS resource set ID. For example, if the serving gNB determines that SRS resource set 1 (SRS resource set ID = 1), SRS resource set 2 (SRS resource set ID = 2), and SRS resource set 3 (SRS resource set ID = 3) are a set of SRS resources that can support bandwidth aggregation, and the bandwidth aggregation resource identifier is included in the configuration information of SRS resource set 1, SRS resource set 2, and SRS resource set 3 (for example, the value of the bandwidth aggregation resource identifier is 1), then SRS resource set 1, SRS resource set 2, and SRS resource set 3 are a set of SRS resources that can support bandwidth aggregation.

[0236] In other words, the first network device may define a new bandwidth aggregated SRS identifier and include the identifier in each associated SRS resource set configuration.

[0237] Step 2104 : The first network device 1021 sends a third message to the second network device 1022 .

[0238] In some embodiments, the name of the third message is not limited, and it can be a "resource response message", a "positioning information response message", etc.

[0239] In some embodiments, when the first network device 1021 is a gNB (e.g., a serving gNB or other gNB) and the second network device is an LMF, the third message may be an NRPPa POSITIONING INFORMATION RESPONSE message.

[0240] In some embodiments, when the first network device 1021 is a gNB-DU and the second network device is a gNB-CU, the third message may be an F1AP positioning information response message.

[0241] In some embodiments, the third message includes the second information.

[0242] In some embodiments, after determining the second information, the first network device 1021 may send the second information to the second network device 1022 via a third message.

[0243] For the explanation of the second information, please refer to steps 2102 and 2103, which will not be repeated here.

[0244] Step 2105 : The second network device 1022 sends a fourth message to the first network device 1021 .

[0245] In some embodiments, the second network device 1022 requires the terminal 101 to send the first signal semi-persistently or aperiodically, and the second network device 1022 sends the fourth message to the first network device 1021 .

[0246] In some embodiments, the semi-persistently or aperiodically transmitted first signal may be a semi-persistently or aperiodically transmitted SRS.

[0247] In some embodiments, the name of the fourth message is not limited, and it can be an "activation request message", "positioning activation request message", etc.

[0248] In some embodiments, when the first network device 1021 is a gNB (e.g., a serving gNB or other gNB) and the second network device is an LMF, the fourth message may be an NRPPa POSITIONING ACTIVATION REQUEST message.

[0249] In some embodiments, when the first network device 1021 is a gNB-DU and the second network device is a gNB-CU, the first message may be an F1 Application Protocol (F1AP) positioning activation request (F1AP POSITIONING ACTIVATION REQUEST) message.

[0250] In some embodiments, the fourth message includes fourth information.

[0251] In some embodiments, the fourth information is used to activate the first signal resource of the bandwidth aggregation.

[0252] In some embodiments, the fourth information is used to activate bandwidth-aggregated positioning signal resources.

[0253] In some embodiments, the fourth information is used to activate bandwidth-aggregated SRS resources.

[0254] In some embodiments, the fourth information is used to activate a bandwidth-aggregated SRS resource set.

[0255] In some embodiments, the name of the fourth information is not limited, and it can be "aggregation activation information", "activation information", "SRS aggregation activation info", etc.

[0256] In some embodiments, the fourth information includes at least one of the following:

[0257] 1) A first activation indication, used to indicate activation of a first resource set in a bandwidth aggregated resource set determined by the first network device based on the first message, so as to activate the bandwidth aggregated resource set, where the bandwidth aggregated resource set includes one or more first signal resource sets.

[0258] In some embodiments, the resource sets for bandwidth aggregation determined by the first network device based on the first message may be one or more. In other words, according to the instruction of the second network device, the SRS resource sets that can be aggregated configured by the first network device may be one or more. For example, the first network device determines that the resource sets that can be bandwidth aggregated are SRS resource sets 1, 2, 3, and 4, where SRS resource sets 1 and 2 constitute aggregated resource set 1, and SRS resource sets 3 and 4 constitute aggregated resource set 2.

[0259] It should be understood that the resource set for bandwidth aggregation can be one or more resource sets, and only one or more of them can be activated. For example, if the resource set for bandwidth aggregation includes aggregated resource set 1 and aggregated resource set 2, only one of the resource sets can be activated when the resource set is activated.

[0260] In some embodiments, the first activation indication may be “bandwidth aggregation activation indication information”.

[0261] For example, when the second information sent by the first network device to the second network device is a "first signal resource set identifier", for example, when the first network device 1021 sends SRS resource set 2 and SRS resource set 3 to the second network device 1022, the first signal resource set identifier "1" corresponding to SRS resource set 1 is included in the configuration information of SRS resource set 2 and SRS resource set 3 to indicate that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are associated resource sets for bandwidth aggregation. Then, the second network device 1022 can send a first activation indication "activation 2" to the first network device 1021, for example, activating SRS resource set 2, which means that the second network device 1022 instructs the first network device 1021 to activate all resource sets associated with SRS resource set 2, that is, activate SRS resource set 1, SRS resource set 2, and SRS resource set 3.

[0262] In some embodiments, the fourth information is included in a semi-persistent information element (IE) of the positioning activation request, and corresponds one-to-one with the SRS resource set ID requested to be activated.

[0263] In some embodiments, the bandwidth aggregation activation indication information is used to indicate whether to activate SRS resources corresponding to other SRS resource set IDs associated with the requested SRS resource set ID to implement SRS positioning measurement of bandwidth aggregation.

[0264] For example, the positioning activation request message includes the following IE:

[0265] In some embodiments, the bandwidth aggregation activation indication information is an optional "aggregation indication" IE. If the IE is set to "true", it means that the indicated SRS resource set ID and other SRS resource ID set(s) associated with it need to be activated at the same time; if the bandwidth aggregation activation indication information does not exist, it means that only the indicated SRS resource ID needs to be activated, and other SRS resource ID set(s) associated with it do not need to be activated.

[0266] 2) A second activation indication is used to indicate activation of a bandwidth aggregated resource set, where the bandwidth aggregated resource set corresponds to the second activation indication.

[0267] In some embodiments, the second activation indication may be a new "first identification" defined for the bandwidth aggregated resource set.

[0268] For example, when the second information sent by the first network device to the second network device is a "bandwidth aggregated resource identifier," for example, the first network device 1021 sends a bandwidth aggregated resource identifier "A" to the second network device 1022, and the bandwidth aggregated resource set includes SRS resource set 1, SRS resource set 2, and SRS resource set 3, indicating that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are resource sets associated with bandwidth aggregation. Then, the second network device 1022 may send a second deactivation instruction "activation A" to the first network device 1021, for example, activating the bandwidth aggregated resource set corresponding to "A," which means that the second network device 1022 instructs the first network device 1021 to activate all resource sets in the bandwidth aggregated resource set, that is, activate SRS resource set 1, SRS resource set 2, and SRS resource set 3. A may be any integer, used to uniquely identify a total bandwidth aggregated resource set.

[0269] For example, the first flag is included in a semi-persistent IE of a positioning activation request, and is used to indicate activation of a group of SRS resources with a specific bandwidth aggregation.

[0270] In some embodiments, the fourth information is a bandwidth aggregation activation indication as a first identifier, wherein the first identifier is included in a first SRS type of the positioning activation request, wherein the first SRS type is a newly defined SRS type, such as aggregation SRS.

[0271] Step 2106 : The first network device 1021 sends an eighth message to the terminal 101 .

[0272] In some embodiments, the eighth message may be an RRC message, or low-layer signaling (eg, MAC CE, DCI).

[0273] In some embodiments, the name of the eighth message is not limited, and it can be "activation indication message", "terminal activation message", "UE SRS resource set activation message", etc.

[0274] In some embodiments, the eighth message includes fourth information, and the fourth information is used to activate the first signal resource of the bandwidth aggregation.

[0275] For an explanation of the fourth information, please refer to step 2105 and will not be repeated here.

[0276] Step 2107 : The first network device 1021 sends a fifth message to the second network device 1022 .

[0277] In some embodiments, the fifth message is used to notify the second network device of activation success or failure.

[0278] In some embodiments, the name of the fifth message is not limited, and it can be "activation feedback message", "positioning activation feedback message", etc.

[0279] In some embodiments, when the first network device 1021 is a gNB (e.g., a serving gNB or other gNB) and the second network device is an LMF, the fifth message may be an NRPPa POSITIONING ACTIVATION RESPONSE message.

[0280] In some embodiments, when the first network device 1021 is a gNB-DU and the second network device is a gNB-CU, the first message may be an F1AP POSITIONING ACTIVATION RESPONSE message.

[0281] In some embodiments, when the first network device successfully activates the first signal resource of bandwidth aggregation, it can feedback fifth information to the second network device to notify the second network device of the successful activation, so that the second network device performs further positioning operations (for example, the second network device sends a measurement request message to other network devices participating in the positioning).

[0282] In some embodiments, when the first network device fails to activate the first signal resource of bandwidth aggregation, it can feedback fifth information to the second network device to notify the second network device of the activation failure, or the fifth information is empty, or the fifth information is not sent, so that the second network device performs further positioning operations (for example, the second network device does not send measurement request messages to other network devices participating in positioning or initiate a new positioning information request process).

[0283] Step 2108: The second network device 1022 sends a sixth message to the network devices participating in the positioning measurement.

[0284] In some embodiments, the sixth message is used to request a measurement.

[0285] In some embodiments, the name of the sixth message is not limited, and may be "measurement request", "positioning measurement request", etc.

[0286] In some embodiments, when the first network device 1021 is a gNB (e.g., a serving gNB or other gNB) and the second network device is an LMF, the sixth message may be an NRPPa measurement request (NRPPa MEASUREMENT REQUEST) message, where the gNB may include a serving gNB and may also include other gNBs.

[0287] In some embodiments, when the first network device 1021 is a gNB-DU and the second network device is a gNB-CU, the first message may be an F1AP measurement request (F1AP MEASUREMENT REQUEST) message.

[0288] In some embodiments, the sixth message includes fifth information, where the fifth information is used to instruct the network devices participating in the positioning measurement to perform joint measurement on the first signal resource of bandwidth aggregation.

[0289] In some embodiments, the name of the fifth information is not limited, and it can be "measurement information", "positioning measurement information", "aggregation measurement information", "SRS aggregation measurement info", etc.

[0290] In some embodiments, the network devices participating in the positioning measurement may include a first network device 1021 and / or at least one third network device 1023 .

[0291] In some embodiments, sending the sixth message to the network devices participating in the positioning measurement may refer to sending the sixth message to the first network device 1021 and / or sending the sixth message to at least one third network device 1023 respectively.

[0292] Step 2109: Terminal 101 sends a first signal.

[0293] In some embodiments, terminal 101 may use bandwidth-aggregated first signal resources to send the first signal.

[0294] In some embodiments, terminal 101 may use a first signal resource with bandwidth aggregation to send a first signal to a network device participating in positioning measurement.

[0295] In some embodiments, the terminal 101 may use the bandwidth-aggregated first signal resource to send a first signal to the first network device 1021 and / or at least one third network device 1023 .

[0296] In some embodiments, the first signal sent by terminal 101 may be one or more.

[0297] In some embodiments, the terminal sends the first signal to enable a network device participating in measuring and positioning to perform positioning measurement on the first information, thereby positioning the terminal 101 .

[0298] Step 2110: The network device participating in the positioning measurement receives and measures the first signal to obtain a measurement result.

[0299] In some embodiments, the network devices participating in the positioning measurement may measure the first signal in response to the sixth message. The network devices participating in the positioning measurement may include the first network device 1021 and / or at least one third network device 1023.

[0300] In some embodiments, the first network device 1021 and / or the at least one third network device 1023 may each perform positioning measurement on the first signal sent by the terminal 101 .

[0301] In some embodiments, the first network device 1021 may perform positioning measurement on the first signal sent by the terminal 101 to obtain a first measurement result.

[0302] In some embodiments, the third network device 1023 may perform positioning measurement on the first signal sent by the terminal 101 to obtain a second measurement result.

[0303] In some embodiments, the measurement result may be Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), etc., which is not limited by the present disclosure. In some embodiments, the first measurement result and / or the second measurement result includes a result of measuring the SRS corresponding to the SRS resource set of the aggregated bandwidth. That is, one measurement result corresponds to one or more SRS resource sets.

[0304] Step 2111: The network device participating in the positioning measurement sends the measurement result to the second network device 1022.

[0305] In some embodiments, the first network device 1021 may send the first measurement result to the second network device 1022 .

[0306] In some embodiments, the third network device 1023 may send the second measurement result to the second network device 1022 .

[0307] Step 2112: The second network device 1022 generates a joint measurement result.

[0308] In some embodiments, the second network device 1022 may generate a joint measurement result based on the first measurement result sent by the first network device 1021 and the at least one second measurement result sent by the at least one third network device 1023 .

[0309] In some embodiments, the joint measurement result is a result of joint measurement of the first signal resource of bandwidth aggregation by the network devices participating in the positioning measurement.

[0310] In some embodiments, the second network device calculates the location of the terminal based on the first measurement result and / or the second measurement result.

[0311] Step 2113 : The second network device 1022 sends a seventh message to the first network device 1021 .

[0312] In some embodiments, the seventh message is used to request deactivation of the bandwidth aggregated first signal resource.

[0313] In some embodiments, the name of the seventh message is not limited, and it can be "deactivation request", "positioning deactivation request", etc.

[0314] In some embodiments, when the first network device 1021 is a gNB (e.g., a serving gNB or other gNB) and the second network device is an LMF, the seventh message may be an NRPPa POSITIONING DEACTIVATION message.

[0315] In some embodiments, when the first network device 1021 is a gNB-DU and the second network device is a gNB-CU, the first message may be an F1AP POSITIONING DEACTIVATION message.

[0316] In some embodiments, the seventh message includes the sixth information.

[0317] In some embodiments, the sixth information is used to deactivate the first signal resource of the bandwidth aggregation.

[0318] In some embodiments, the name of the sixth information is not limited, and it can be "aggregation deactivation information", "deactivation information", "SRS aggregation deactivation info", etc.

[0319] In some embodiments, the sixth information includes at least one of the following:

[0320] 1) a first deactivation instruction, used to instruct the first network device to deactivate a first resource set in the bandwidth aggregated resource set determined based on the first message, so as to activate the bandwidth aggregated resource set, where the bandwidth aggregated resource set includes one or more first signal resource sets;

[0321] In some embodiments, the first deactivation indication may be "bandwidth aggregation deactivation indication information".

[0322] For example, when the second information sent by the first network device to the second network device is a "first signal resource set identifier", for example, when the first network device 1021 sends SRS resource set 2 and SRS resource set 3 to the second network device 1022, the first signal resource set identifier "1" corresponding to SRS resource set 1 is included in the configuration information of SRS resource set 2 and SRS resource set 3 to indicate that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are associated resource sets for bandwidth aggregation. Then, the second network device 1022 can send a first deactivation indication "deactivation 2" to the first network device 1021, for example, deactivating SRS resource set 2, which means that the second network device 1022 instructs the first network device 1021 to deactivate all resource sets associated with SRS resource set 2, that is, to deactivate SRS resource set 1, SRS resource set 2, and SRS resource set 3.

[0323] For example, in some embodiments, the bandwidth aggregation deactivation indication information is used to instruct deactivation of SRS resources corresponding to a specific SRS resource set ID and SRS resources corresponding to other associated SRS resource set IDs, so as to implement deactivation of SRS resources for bandwidth aggregation.

[0324] For example, the positioning deactivation message includes the following IE:

[0325] In some embodiments, if the bandwidth aggregation deactivation indication information is an optional "aggregation indication" IE, if the IE is set to "true", it means that the SRS resource ID set and other SRS resource ID set(s) associated with it need to be deactivated at the same time; if the bandwidth aggregation deactivation indication information does not exist, it means that only the indicated SRS resource ID needs to be deactivated, and there is no need to deactivate other SRS resource ID set(s) associated with it.

[0326] 2) A second deactivation indication, used to indicate deactivation of a bandwidth aggregated resource set, where the bandwidth aggregated resource set corresponds to the second activation indication.

[0327] In some embodiments, the second activation indication may be a new “second identifier” defined for the bandwidth aggregated resource set.

[0328] For example, when the second information sent by the first network device to the second network device is a "bandwidth aggregated resource identifier", for example, the first network device 1021 sends a bandwidth aggregated resource identifier "A" to the second network device 1022, and the bandwidth aggregated resource set includes SRS resource set 1, SRS resource set 2, and SRS resource set 3, to indicate that SRS resource set 1, SRS resource set 2, and SRS resource set 3 are resource sets associated with bandwidth aggregation. Then, the second network device 1022 can send a second deactivation instruction "deactivation A" to the first network device 1021, for example, to deactivate the bandwidth aggregated resource set corresponding to "A", which means that the second network device 1022 instructs the first network device 1021 to deactivate all resource sets in the bandwidth aggregated resource set, that is, to deactivate SRS resource set 1, SRS resource set 2, and SRS resource set 3.

[0329] In some embodiments, the first flag is included in a semi-persistent IE of a positioning activation request, for indicating activation of a group of SRS resources of a specific bandwidth aggregation.

[0330] In some embodiments, the second identifier is included in the first termination transmission information in the positioning deactivation message, where the first termination transmission information is a newly defined termination transmission type, such as aggregation SRS.

[0331] In some embodiments, steps 2105-2107 may be optional. Steps 2105-2107 may be performed in the case of a semi-persistent or aperiodic SRS, but may not be performed otherwise. In other words, in the case of a periodic SRS, the second network device does not need to send an activation request to the first network device.

[0332] In some embodiments, step 2112 may be an optional step.

[0333] In some embodiments, the above optional steps mean that one step or multiple steps can be performed, and one or more of these steps can be omitted or replaced in different embodiments.

[0632] The following is an exemplary introduction to the above method.

[0633] FIG8 is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure.

[0634] Step 8101: LMF sends an NRPPa positioning signal request message to the serving base station.

[0635] In some embodiments, the positioning signal request message includes first information, wherein the first information is used to request the serving base station (serving NB) for bandwidth aggregation SRS configuration; the specific meaning of the request is that the LMF requests the serving base station to configure uplink S RS configuration information for the UE.

[0636] In some embodiments, the first information includes at least one of the following information: a bandwidth aggregation indication, used to indicate that the base station needs to provide SRS configuration information for bandwidth aggregation; an aggregated bandwidth, used to indicate the size of the desired aggregated bandwidth; the number of carriers of the aggregated bandwidth, used to indicate the number of carriers that the aggregated bandwidth can span, such as 2 or 3; and conditional information of the aggregated bandwidth, used to indicate the conditions under which the aggregated bandwidth needs to be configured, such as the same period and offset, or time slot offset.

[0637] In some embodiments, the bandwidth aggregation indication may be defined as a resource type. In some embodiments, the condition information of the aggregated bandwidth may include parameters indicating that the same value is required, or may also include specific values ​​of the parameters that require the same value.

[0638] In some embodiments, the serving base station determines SRS resources that can be bandwidth aggregated based on the first information.

[0639] Step 8102: After determining the SRS resources, the serving base station sends the SRS configuration to the UE.

[0640] In some embodiments, the SRS configuration includes second information, where the second information is used to indicate bandwidth-aggregated SRS resources.

[0641] Step 8103: After the serving base station determines the SRS resources, it sends a positioning information feedback message to the LMF.

[0642] In some embodiments, the positioning information feedback message includes second information, where the second information is used to indicate bandwidth-aggregated SRS resources.

[0643] The following embodiments may be applied to step 8102 and step 8103:

[0644] In some embodiments, the second information is determined by the serving base station based on the first information.

[0645] In some embodiments, the second information is determined by the serving base station based on the first information and its own resources.

[0646] In some embodiments, the second information includes a first identifier, and the first identifier is used to indicate an SRS resource of the associated bandwidth aggregation.

[0647] In some embodiments, the first identifier may include at least one of the following: an associated SRS resourceset ID, a bandwidth aggregated resource identifier.

[0648] In some embodiments, the associated SRS resourceset ID may be included in the SRS resource set configuration and associated with the SRS resourceset ID in the SRS resourceset, where the associated SRS resourceset ID is used to indicate the SRS resourceset associated with the SRS resourceset ID.

[0649] For example, if the serving gNB determines that SRS resourceset 1 (SRS resourceset ID = 1), SRS resourceset 2 (SRS resourceset ID = 2), and SRS resourceset 3 (SRS resourceset ID = 3) are a set of SRS resources that can be bandwidth aggregated, the configuration information of SRS resourceset 2 and SRS resourceset 3 includes an associated SRS resourceset ID, and the associated SRS resourceset ID is SRS resourceset ID = 1.

[0650] In some embodiments, the resource identifier of the bandwidth aggregation is included in the SRS resource set configuration, and corresponds one-to-one with the SRS resourceset ID in the SRS resourceset, and the associated SRS resourceset ID is used to indicate the SRS resourceset associated with the SRS resourceset ID.

[0651] For example, if the serving base station determines that SRS resourceset 1 (SRS resourceset ID=1), SRS resourceset 2 (SRS resourceset ID=2), and SRS resourceset 3 (SRS resourceset ID=3) are a group of SRS resources that can be bandwidth aggregated, and the configuration information of SRS resourceset 1, SRS resourceset 2, and SRS resourceset 3 includes a resource identifier for bandwidth aggregation (for example, the value of the resource identifier for bandwidth aggregation is 1), then it means that SRS resourceset 1, SRS resourceset 2, and SRS resourceset 3 are a group of SRS resources that can support bandwidth aggregation.

[0652] In step 8104, in the case of semi-persistent or aperiodic SRS, the LMF sends an NRPPa Positioning Activation Request message to the target device's serving base station to request activation of UE SRS transmission. The serving base station activates UL-SRS transmission and sends an NRPPa Positioning Activation Response message. The target device begins transmitting UL-SRS according to the time domain behavior of the UL-SRS resource configuration.

[0653] In some embodiments, the positioning activation request message includes third information, wherein the third information is used to activate bandwidth-aggregated SRS resources.

[0654] In some embodiments, the third information includes at least one of the following information: bandwidth aggregation activation indication information and a first identifier.

[0655] In some embodiments, the third information is bandwidth aggregation activation indication information, which is included in a semi-persistent IE of a positioning activation request and corresponds one-to-one to the SRS resource set ID requested for activation.

[0656] In some embodiments, the bandwidth aggregation activation indication information is used to indicate whether to activate SRS resources corresponding to other SRS resource set IDs associated with the requested SRS resource set ID to implement SRS positioning measurement of bandwidth aggregation.

[0657] In some embodiments, the bandwidth aggregation activation indication information is an optional "aggregation indication" IE. If the IE is set to "true", it means that the indicated SRS resource set ID and other SRS resource ID set(s) associated with it need to be activated at the same time; if the bandwidth aggregation activation indication information does not exist, it means that only the indicated SRS resource ID needs to be activated, and other SRS resource ID set(s) associated with it do not need to be activated.

[0658] In some embodiments, the third information is a bandwidth aggregation activation indication as a first identifier, wherein the first identifier is included in a semi-persistent IE of a positioning activation request and is used to indicate activation of a group of specific bandwidth aggregated SRS resources.

[0659] In some embodiments, the third information is a bandwidth aggregation activation indication as a first identifier, wherein the first identifier is included in a first SRS type of the positioning activation request, wherein the first SRS type is a newly defined SRS type, such as aggregation SRS.

[0660] Step 8105: The LMF provides the UL-SRS configuration description to the selected gNB in ​​the NRPPa measurement request message.

[0661] In some embodiments, the measurement request message includes fourth information, wherein the fourth information is used to instruct the TRPs participating in the positioning measurement to perform joint measurement on the SRS resources of the bandwidth aggregation. The selected base station can be a serving base station or a neighboring base station.

[0662] In some embodiments, the fourth information includes at least one of the following information: a bandwidth aggregation measurement indication, and the second information.

[0663] In step 8106 , each base station participating in the positioning measurement measures the SRS signal according to the information in step 105 .

[0664] In step 8107, each base station participating in the positioning measurement provides the measurement result of the SRS signal to the LMF through the NRPPa measurement feedback message.

[0665] Step 8108: LMF sends a positioning deactivation message to the serving base station.

[0666] In some embodiments, the positioning deactivation message includes fifth information, wherein the fifth information is used to indicate deactivation of bandwidth aggregated SRS resources.

[0667] In some embodiments, the fifth information includes at least one of the following information: bandwidth aggregation deactivation indication information and a first identifier.

[0668] In some embodiments, if the associated SRS resource set ID is used in step 8103, the fifth information is bandwidth aggregation deactivation indication information, and the fifth information is included in the deactivation SRS resourcesetIE of positioning deactivation, corresponding one-to-one to the SRS resource set ID requested to be activated.

[0669] In some embodiments, the bandwidth aggregation deactivation indication information is used to indicate deactivation of SRS resources corresponding to a specific SRS resource set ID and SRS resources corresponding to other associated SRS resource set IDs, so as to implement deactivation of SRS resources for bandwidth aggregation.

[0670] In some embodiments, if the bandwidth aggregation deactivation indication information is an optional "aggregation indication" IE, if the IE is set to "true", it means that the SRS resource ID set and other SRS resource ID set(s) associated with it need to be deactivated at the same time; if the bandwidth aggregation deactivation indication information does not exist, it means that only the indicated SRS resource ID needs to be deactivated, and there is no need to deactivate other SRS resource ID set(s) associated with it.

[0671] In some embodiments, the fifth information is a bandwidth aggregation deactivation indication as a first flag, wherein the first flag is included in a semi-persistent IE of a positioning activation request and is used to indicate activation of a group of specific bandwidth aggregated SRS resources.

[0672] In some embodiments, the fifth information is a bandwidth aggregation deactivation indication as a first identifier, wherein the first identifier is included in the first termination transmission information in the positioning deactivation message, wherein the first termination transmission information is a newly defined termination transmission type, such as aggregation SRS.

[0673] In some embodiments, the above method can implement SRS resource configuration, activation, measurement, and deactivation processes supporting bandwidth aggregation, thereby improving positioning accuracy.

[0674] It should be understood that in order to support the positioning process under the CU-DU separation architecture, in some embodiments, the signaling interaction between the above-mentioned LMF and ServinggNB can replace LMF with gNB-CU, servinggNB with gNB-DU, and NRPPa with F1AP.
