[0039] The method, terminal, and network-side device for receiving positioning signals provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0040] In some embodiments of this application, Figure 2 One method for transmitting a location signal according to an embodiment of this application is shown, the method being applied to a terminal, such as... Figure 2 As shown, the method includes:

[0041] Step 202: When the probe reference signal is configured on N target carriers, determine the transmission of the probe reference signal based on one or more of the following information: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0042] Where N is an integer greater than or equal to 2.

[0043] In this embodiment, N carriers can be carriers of different frequency ranges, carriers of different cells, and carriers of different frequency layers, etc. In one possible embodiment, N carriers can also be understood as N cells, or N BWPs, etc. The terminal configures a probe reference signal on N target carriers, where N is an integer greater than or equal to 2. The transmission of the configured probe reference signal can be determined by at least one of the following: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters. This determines the transmission mode, transmission power, and / or spatial relationship of the probe reference signal, such as independent transmission, aggregated transmission, etc.

[0044] This application can effectively standardize the transmission of different types of carriers and different types of probe reference signals, realize the aggregation transmission and / or aggregation measurement of probe reference signals, and can simultaneously activate probe reference signals on multiple carriers for aggregation transmission and / or measurement, thereby improving the positioning speed and positioning accuracy of the terminal.

[0045] The carrier aggregation parameters include: time offset parameters (such as frame offset parameter SFN0), carrier offset (CA-offset) parameters, power offset parameters, frequency offset parameters, phase offset parameters, and receive and transmit time difference offset parameters.

[0046] Carrier aggregation parameters also include configuration or auxiliary information for aggregating transmissions or aggregating measurements.

[0047] The power control types include one or more of the following:

[0048] Closed-loop power control, open-loop power control, aggregated power control, non-aggregated power control;

[0049] The types of probe reference signals include one or more of the following:

[0050] Periodic detection reference signal, aperiodic detection reference signal, semi-static detection reference signal, aggregated detection reference signal (or first detection reference signal), and non-aggregated detection reference signal (or second detection reference signal);

[0051] The aggregated detection reference signal (first detection reference signal) includes one or more of the following:

[0052] Inter-band aggregation detection reference signal, intra-band aggregation detection reference signal, continuous aggregation detection reference signal, and discontinuous aggregation detection reference signal.

[0053] In some embodiments of this application, the probe reference signal has symbols that are the same or overlap in the transmission time domain on at least two carriers.

[0054] In the embodiments of this application, the probe reference signals have the same transmission time domain position or overlapping symbols on different carriers. Specifically, at least two carriers can be any two carriers from N first carriers, and can belong to different frequency ranges or different cells. That is, on any two carriers configured with probe reference signals, the probe reference signals have the same time domain position or overlapping symbols.

[0055] In some embodiments of this application, the method for transmitting a positioning signal further includes: receiving configuration information or target information of N target carriers, wherein the target information includes at least one of the following: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0056] In this embodiment, when N target carriers are configured with probe reference signals, the terminal receives configuration information from the network side. This configuration information corresponds to the N target carriers and can instruct the transmission (e.g., transmission method and transmission rules) of the N target carriers and their corresponding probe reference signals. It is worth noting that the configuration information received from the network side can also be configuration information for some of the N target carriers, or partial configuration information for a portion of the N target carriers. For example, it may receive aggregation indication information for only M carriers, or adjust the configuration information for only C carriers. Alternatively, the terminal receives target information from the network-side device and determines the transmission (e.g., transmission method and transmission rules) of the probe reference signals based on one or more pieces of information in the target information.

[0057] The target information specifically includes: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0058] In some embodiments of this application, the N target carriers include a first carrier configured with aggregation indication, and / or a second carrier not configured with aggregation indication; and / or the probe reference signal includes a first probe reference signal transmitted in aggregation, and / or a second probe reference signal transmitted in non-aggregation.

[0059] In this embodiment, the N target carriers include carriers configured with aggregation indicators and carriers without aggregation indicators. The carriers configured with aggregation indicators are aggregated into a first carrier, and the carriers without aggregation indicators are the aforementioned second carriers.

[0060] Correspondingly, the probe reference signal may also include a first probe reference signal that is indicated for aggregate transmission, such as the first probe reference signal being aggregated and transmitted according to the corresponding aggregation indication. The probe reference signal may also include a second probe reference signal that is not indicated for aggregate transmission, that is, transmitted in a non-aggregated transmission manner.

[0061] The aggregation indication can be understood as any of the following: the N1 carriers are configured with relevant indication information, indicating that the N1 carriers can be aggregated or partially aggregated, and the N1 carriers can be understood as the first carrier; or, by aggregating a carrier group, which contains N2 carriers, the N2 carriers can also be understood as the first carrier; or, for example, a cross-carrier probe reference signal is configured, and the carrier transmitted by the probe reference signal is the first carrier.

[0062] The aggregated transmission can be understood as the transmission of a probe reference signal on N3 carriers, where the probe reference signal is the first probe reference signal; it can also be understood as the transmission of a probe reference signal mapped onto N4 carriers, where the probe reference signal is the first probe reference signal; or it can be understood as the transmission of N5 probe reference signals on N6 carriers according to a specified rule, where the probe reference signal is the first probe reference signal.

[0063] In some embodiments of this application, a first detection reference signal is transmitted on a first carrier; and / or a second detection reference signal is transmitted on a second carrier.

[0064] In this embodiment, the first carrier is configured with an aggregation indication, and the first probe reference signal is transmitted via aggregation on the carriers of the first carrier. This can also be understood as the first probe reference signal being transmitted via aggregation on multiple first carriers. Specifically, the first probe reference signal can be transmitted on all first carriers or on a subset of the first carriers.

[0065] The second probe reference signal, which is transmitted without aggregation, can be transmitted on a second carrier that is not configured with aggregation indication.

[0066] In some embodiments of this application, the method of sending a positioning signal further includes: receiving configuration information of a probe reference signal, wherein the configuration information of the probe reference signal includes one or more of the following: probe reference signal configuration information, probe reference signal configuration update configuration information, carrier configuration information, configuration information of a first carrier configured with an aggregation indication, and configuration information of a first probe reference signal.

[0067] In this embodiment of the application, the terminal receives configuration information of the probe reference signal sent by the network-side device. Through this configuration information, the terminal can obtain settings such as the transmission power, transmission order, transmission resources (such as transmission carrier, time domain information, frequency domain information, etc.), transmission priority, and spatial relationship of the probe reference signal.

[0068] The time-domain information includes one or more of the following: time slot offset, symbol offset, period value set, silence parameter set, repetition index set, frequency domain offset, and comb size.

[0069] The frequency domain information includes one or more of the following: frequency layer information, carrier information, bandwidth part (BWP) information, starting resource position in the physical resource block (PRB), and bandwidth in the PRB.

[0070] Specifically, the configuration information of the probe reference signal includes one or more of the following: probe reference signal configuration information, probe reference signal configuration update information, carrier configuration information, configuration information of the first carrier configured with aggregation indication, and configuration information of the first probe reference signal. The probe reference signal configuration information is used to directly configure the probe reference signal. The probe reference signal configuration update information is used to update the configuration information of the probe reference signal. The carrier configuration information is used to directly configure the carrier and / or the signals on the carrier. The configuration information of the first carrier configured with aggregation indication can configure all or some of the first carriers, or configure all or some of the signals in the first carrier. The configuration information of the first probe reference signal is used to configure the aggregated first probe reference signal separately or uniformly.

[0071] In some embodiments of this application, the aggregation indication is configuration information or indication information of the first carrier; or the aggregation indication is configuration information or indication information of the first unit; or the aggregation indication is configuration information or indication information of the first detection reference signal; wherein the first unit includes at least two target carriers, or the first unit includes at least two first carriers.

[0072] In the embodiments of this application, the aggregation indication can be used as configuration information or indication information for the first carrier, that is, the aggregation indication can be used to configure or indicate all or part of the first carrier.

[0073] The aggregation indication can also be the configuration information of the first unit, wherein the first unit includes at least two target carriers or first carriers. That is, the aggregation indication configures or indicates several target carriers in the first unit, or configures or indicates several first carriers in the first unit, or indicates the overall configuration or control of carriers or signals in the first unit.

[0074] The aggregation indicator can also serve as configuration or indication information for the first probe signal, i.e., the aggregation indicator can be used to configure or indicate the first probe reference signal transmitted via aggregation.

[0075] The aggregation indication is included in the configuration information or indication information of the first carrier; or;

[0076] The aggregation instruction is included in the configuration information or instruction information of the first unit; or;

[0077] The aggregation indication is included in the configuration information or indication information of the first detection reference signal.

[0078] In some embodiments of this application, determining the transmission of the probe reference signal includes one or more of the following: determining the transmission mode of the probe reference signal; determining the transmission power of the probe reference signal; and determining the spatial relationship of the probe reference signal.

[0079] In this embodiment, determining the transmission of the probe reference signal specifically refers to determining the transmission method, transmission power, and spatial relationship of the probe reference signal during transmission. Specifically, the transmission method includes aggregated transmission, non-aggregated transmission, and the order or priority of transmission. The transmission power is specific to the transmission power of each or every probe reference signal. It is worth noting that the transmission method, transmission power, and spatial relationship of the first probe reference signal in aggregated transmission are important aspects of this application. Through effective control, the first probe reference signal can better assist in position measurement, achieving higher positioning accuracy. Since the total power used by the terminal to transmit the probe reference signal is fixed, the transmission power of some probe reference signals can be configured based on parameters such as the priority and carrier bandwidth ratio of different probe reference signals. Determining the transmission of the probe reference signal also includes determining the spatial relationship of the probe reference signals, where the spatial relationships of multiple probe reference signals can be consistent or inconsistent. In one possible embodiment, all first carriers, or first units, or first probe reference signals are determined to have the same transmission method, the same priority, uniformly scheduled transmission power, and configured spatial relationships, among at least one of these.

[0080] In some embodiments of this application, the transmission of the probe reference signal is determined according to priority rules, including one or more of the following:

[0081] The transmission power of the detection reference signal is determined according to the first priority rule;

[0082] The transmission method of the detection reference signal is determined according to the second priority rule;

[0083] The priority of the configuration information for the detection reference signal is determined according to the third priority rule;

[0084] The spatial relationship of the probe reference signal is determined according to the fourth priority rule.

[0085] In this embodiment, the transmission power of different detection reference signals is allocated according to a first priority rule. It is understood that the transmission power of detection reference signals with higher priority is given priority consideration.

[0086] The second priority rule indicates the transmission method and order of different probe reference signals. It is understandable that probe reference signals with higher priority are guaranteed to be transmitted first; for example, aggregated probe reference signals or the first probe reference signal can be transmitted first.

[0087] The actual configuration information used to transmit the probe reference signal is determined according to the third priority rule. It can be understood that, generally, one or more probe reference signals are configured according to the configuration information of the probe reference signal with the highest priority. In one embodiment, if multiple first carriers or first units are configured with different configuration information, the configuration information used to transmit the probe reference signal is determined according to the priority or the third priority rule. For example, when multiple probe reference signals are aggregated into a first probe reference signal, and the configuration information of the multiple probe reference signals is different, the configuration information of the first probe reference signal is determined according to the priority or the third priority rule.

[0088] The spatial relationships of multiple probe reference signals are configured according to the fourth priority rule. It is understood that priority is given to ensuring the successful configuration of the spatial relationships of probe reference signals with higher priority. Alternatively, it can be understood that multiple probe reference signals transmitted simultaneously or overlappingly, or probe reference signals on multiple carriers, have different spatial relationships, which are determined according to priority or the fourth priority rule. In one embodiment, three probe reference signals are configured with spatial relationships 1, 2, and 3, respectively. However, the terminal can only transmit the probe reference signals according to one or two spatial relationships simultaneously within a certain time period. The terminal can transmit only one or two probe reference signals corresponding to the spatial relationships according to priority or the fourth priority rule, or it can transmit all probe reference signals according to the highest priority spatial relationship.

[0089] The first, second, third, and fourth priority rules can be priority rules defined by the protocol. Assuming events A, B, C, and D exist, the protocol can specify the priority of at least one of A, B, C, and D, or it can specify the order of the priorities of events A, B, C, and D. A, B, C, and D are merely descriptive examples; there may be more or fewer events.

[0090] In some embodiments of this application, the first priority rule includes one or more of the following:

[0091] Power allocation priority for the target carrier;

[0092] Power allocation priority for the probe reference signal;

[0093] The power allocation priority for the third carrier of the probe reference signal is not configured;

[0094] Power allocation priority for N target carriers and the third carrier;

[0095] Power allocation priority for other signals or channels; where other signals or channels are signals or channels different from the detection reference signal;

[0096] The power allocation priority for the first probe reference signal and other signals or channels.

[0097] In the embodiments of this application, the first priority rule includes the power allocation priority of the target carrier, that is, determining the priority order of one or more target carriers among multiple target carriers. It can be understood that the transmission power of the target carrier with higher priority is prioritized to be configured.

[0098] The first priority rule also includes the power allocation priority of multiple probe reference signals, that is, determining the priority order of one or more probe reference signals or carriers among multiple probe reference signals or multiple carriers corresponding to probe reference signals. It can be understood that priority is given to ensuring that the transmission power of probe reference signals or their corresponding carriers with higher priority is configured.

[0099] The first priority rule also includes the power allocation priority of the third carrier without a probe reference signal, that is, determining the priority order of one or more third carriers. It should be understood that the transmission power of the third carrier is determined according to the priority or the first priority rule, or the transmission power of the target carrier and the priority of the power allocation of the third carrier are determined.

[0100] The first priority rule also includes the power allocation priority of other signals or channels, which are signals or channels different from the probe reference signal. It should be understood that the power allocation of these other signals or channels is determined according to priority or priority rules. This can also be understood as the transmission power of other signals or channels determined according to priority, while ensuring that the transmission power of the reference probe signal is configured. Furthermore, it can be understood as the priority of the transmission power of the probe reference signal and the power allocation of other signals or channels.

[0101] The first priority rule also includes the power allocation priority between the first sounding reference signal and other signals or channels. Specifically, the first sounding reference signal has a higher priority than other signals or channels. That is, when allocating power to the first sounding reference signal and other signals or channels, priority is given to ensuring that the transmission power of the first sounding reference signal is configured, and vice versa.

[0102] In some embodiments of this application, the N target carriers satisfy at least one of the following:

[0103] The N target carriers include primary cell carriers and secondary cell carriers; and / or

[0104] The N target carriers include carriers located in the uplink and carriers supplementing the uplink; and / or

[0105] The N target carriers include carriers with scheduled PUSCH and carriers without scheduled PUSCH; and / or

[0106] Multiple probe reference signals on N target carriers include probe reference signals of different priorities; and / or

[0107] The detection reference signals on the N target carriers include a first detection reference signal and a second detection reference signal; and / or

[0108] The detection reference signals on the N target carriers include detection reference signals used for positioning and detection reference signals not used for positioning.

[0109] The priority rule can be understood as A having a higher priority than B, or B having a higher priority than A, that is, prioritizing the power allocation of A or B. A can be understood as at least one of the following: primary cell carrier, uplink carrier, carrier with scheduled PUSCH, first priority probe reference signal, first probe reference signal, probe reference signal used for positioning. B can be understood as at least one of the following: secondary cell carrier, supplementary uplink carrier, carrier without scheduled PUSCH, xth priority probe reference signal, second probe reference signal, probe reference signal not used for positioning.

[0110] In this embodiment, the first priority rule further includes the power allocation priority between the third carrier and the N target carriers. Specifically, it includes the power priority allocation between the third carrier and the N target carriers, the power priority allocation among multiple third carriers, and the power priority allocation among the N target carriers. The power priorities of the third carrier and the N target carriers are different; for example, the power priority of the third carrier may be higher or lower than the power priority of the N target carriers.

[0111] The first priority rule also includes the power allocation priority of the probe reference signal and / or the first signal. Specifically, it includes the power priority allocation among multiple probe reference signals, the power priority allocation between the probe reference signal and the first signal, and the power priority allocation among multiple first signals. The power allocation priorities of the probe reference signal and the first signal are different; for example, the priority of the probe reference signal may be higher or lower than the power allocation priority of the first signal.

[0112] The first signal is specifically a signal other than the detection reference signal, or another channel, such as PRACH, PUCCH, PUSCH, etc.

[0113] Furthermore, among the N target carriers, there are one or more of the following: primary cell carrier and secondary cell carrier, uplink carrier and supplementary uplink carrier, carrier with scheduled PUSCH and carrier without scheduled PUSCH. The probe reference signals on the target carriers include one or more of the following: probe reference signals of different priorities, the aforementioned first probe reference signal and the aforementioned second probe reference signal, probe reference signals used for positioning and probe reference signals not used for positioning.

[0114] In some implementations, when M target carriers are located in the same aggregated carrier group (or first unit), the target carriers in the same aggregated carrier group have the same power allocation priority.

[0115] In some embodiments of this application, the transmission power of the probe reference signal is determined according to a first priority rule, including one or more of the following:

[0116] Based on the received first priority indication information, determine the power allocation priority of N target carriers;

[0117] Based on the first priority indication information, determine the power allocation priority of the detection reference signal on the N target carriers.

[0118] In this embodiment of the application, the power allocation priority of N target carriers is determined based on the received first priority indication information associated with the first priority rule. The first priority rule can be a priority rule defined by a protocol, i.e., setting the power priority of the target carriers.

[0119] It can also determine the power allocation priority of the probe reference signals on N target carriers based on the received first priority indication information, that is, set the power priority of the probe reference signals on the target carriers. For example, the priority of the target carriers or the priority of the probe reference signals can be configured directly.

[0120] In some embodiments of this application, the method of determining the transmission of the detection reference signal includes one or more of the following:

[0121] Based on the downlink control information, determine the transmission method of the detection reference signal;

[0122] Based on the type of the detection reference signal, determine the transmission method of the detection reference signal on N target carriers;

[0123] Based on the aggregation instruction, determine the transmission method of the probe reference signal;

[0124] The transmission method of the detection reference signal for the first target wave is determined based on the carrier aggregation parameters or the parameters of the first carrier configured with aggregation indication.

[0125] In this embodiment, determining the transmission mode of the probe reference signal can be based on downlink control information (DCI), or on the type of the probe reference signal, such as aggregated, non-aggregated, periodic, or aperiodic. Alternatively, the transmission mode can be determined based on an aggregation indication, or on carrier aggregation parameters or parameters of a first carrier configured with an aggregation indication.

[0126] In some embodiments of this application, the second priority rule includes: the transmission priority of a plurality of first detection reference signals; and / or the transmission priority of the first detection reference signal and the second detection reference signal.

[0127] In this embodiment, the second priority rule includes the transmission priority of multiple first detection reference signals. It is understood that among the multiple first detection reference signals, the first detection reference signal with the higher priority is prioritized for transmission. The second priority rule also includes the transmission priority between the first detection reference signal and the second detection reference signal. For example, if the transmission priority of the first detection reference signal is higher than that of the second detection reference signal, then the first detection reference signal is prioritized for transmission.

[0128] In some embodiments of this application, the transmission method of the detection reference signal is determined according to the second priority rule, including one or more of the following:

[0129] Multiple first detection reference signals are sent in a first predetermined order;

[0130] According to the second predetermined order, a first detection reference signal is transmitted on a portion of the N target carriers;

[0131] According to the third predetermined sequence, a first detection reference signal is transmitted on the carrier wave of the first unit.

[0132] The first unit includes a plurality of first carriers or a plurality of target carriers configured with aggregation indication.

[0133] In the embodiments of this application, multiple first detection reference signals can be transmitted sequentially, in a polling manner, or selectively according to a first preset order. Alternatively, the transmission priority of one or more detection reference signals among the multiple first detection reference signals can be determined according to the first preset order.

[0134] Alternatively, a first probe reference signal can be transmitted on a subset of the N target carriers according to a second predetermined order. This means a first probe reference signal is transmitted on a subset of the N carriers. The transmission priority of a first probe reference signal on a carrier can also be determined according to this second predetermined order. In one embodiment, the second predetermined order is to select carriers with large aggregation bandwidth and transmit the first probe reference signal. In another embodiment, the second predetermined order is to select carriers that satisfy a specified aggregation rule and transmit the first probe reference signal. In yet another embodiment, the first probe reference signal is transmitted according to a second predetermined order related to the priority rule described above.

[0135] Alternatively, a first detection reference signal can be transmitted on the carrier of the first unit according to a third preset order. This can also be understood as transmitting on all or part of the carriers in the first unit according to a third preset order associated with the second priority. Alternatively, the priority of a first detection reference signal on all or part of the carriers in the first unit can be determined according to the third preset order.

[0136] The first detection reference signals in multiple first units can be sent sequentially according to the fourth preset order, and the sending priority of the first detection reference signals in multiple first units can be determined according to the fourth preset order.

[0137] The first unit includes multiple first carriers configured with aggregation indication, or the first unit includes multiple target carriers. The aggregation detection reference signal group includes a first setting order and a second setting order, the carrier configuration information includes a third setting order, and the configuration information of the first unit includes a fourth setting order. The first setting order, the second setting order, the third setting order, and the fourth setting order can be a protocol-defined setting order or a network configuration setting order.

[0138] In some embodiments of this application, the transmission mode of the detection reference signal is determined based on downlink control information, including one or more of the following:

[0139] Activate the transmission of the probe reference signal in accordance with the method specified in the downlink control information;

[0140] Activate the target carrier of the probe reference signal in accordance with the method specified in the downlink control information.

[0141] In this embodiment, the transmission of the probe reference signal and the carrier carrying the probe reference signal is determined according to the downlink control information (DCI). Specifically, this may include activating the transmission of one or more probe reference signals in a manner specified by the downlink control information (DCI). It may also involve activating the transmission of one or more target carriers of the first probe reference signal in a manner specified by the downlink control information (DCI). In one possible embodiment, the transmission of the first probe reference signal on all target carriers and the first carrier can be activated by a single downlink control command. If the first probe reference signal is composed of multiple probe reference signals aggregated together, the aggregated transmission of the multiple probe reference signals, i.e., the transmission of the first probe reference signal, can also be activated by a single downlink control information.

[0142] Specifically, the downlink control information (DCI) activates the simultaneous transmission of sounding reference signals on at least two carriers, or the downlink control information (DCI) activates the polling transmission of sounding reference signals on at least two carriers.

[0143] In some embodiments of this application, the third priority rule includes one or more of the following:

[0144] The priority of the configuration information of the first carrier and / or the configuration information of the second carrier;

[0145] Priority of configuration information for the first unit and / or other target carrier configuration information;

[0146] The priority of the configuration information of the first configuration mode on the first detection reference signal and / or the configuration information of the second configuration mode on the first detection reference signal;

[0147] Priority of configuration information for multiple first detection reference signals;

[0148] The priority of the configuration information of the first probe reference signal on the first bandwidth portion and / or the configuration information of the first probe reference signal on the second bandwidth portion.

[0149] The first unit consists of multiple first carriers or multiple target carriers configured with aggregation indicators.

[0150] The configuration information of the first unit consists of configuration information for multiple first carriers or multiple target carriers configured with aggregation indications. In one embodiment, it can be understood that the carriers of the first unit use the same configuration information.

[0151] In this embodiment, the third priority rule can be the priority between the configuration information of the first carrier, the priority between the configuration information of the second carrier, or the priority between the configuration information of the first carrier and the configuration information of the second carrier. When the third priority rule is the priority between the configuration information of the first carrier and the configuration information of the second carrier, there is a priority relationship; for example, the priority of the configuration information of the first carrier is higher than the priority between the configuration information of the second carrier. In one possible embodiment, the probe reference signal is transmitted on multiple first carriers, but the configuration information of the first carriers is different, such as subcarriers, cyclic prefix CP, group number u, etc. The configuration information of the carrier with lower priority is reconfigured or configured according to the configuration information of the carrier with higher priority.

[0152] The third priority rule may also include the priority of the configuration information of the first unit and / or the configuration information of other target carriers. Specifically, the first unit includes a first carrier or some target carriers configured with aggregation indication. The configuration information of the first unit may also correspond to the configuration information of the first carrier or target carrier according to the priority, or the priority among the configuration information of multiple first units or the priority of the configuration information of multiple other target carriers, or the priority of the configuration information of the first unit and other target carriers.

[0153] The third priority rule may also include the priority among the configuration information of multiple first detection reference signals, the priority among the configuration information of multiple second detection reference signals, and the priority between the configuration information of the first detection reference signal and the configuration information of the second detection reference signal.

[0154] The third priority rule may also include the priority of configuration information for different configuration methods on the first detection reference signal. These different configuration information may include the first configuration method, the second configuration method, and possibly the third, fourth, ..., Nth configuration method. This application does not limit this. For example, the configuration information of the MAC CE configuration can replace the configuration information of the RRC, meaning that the priority of the MAC CE configuration information is higher than that of the RRC configuration information.

[0155] The third priority rule can also include the priority of multiple configuration information for multiple first detection reference signals, where the multiple configuration information can be different. This can also be understood as: if multiple first detection reference signals are configured with different configuration information, and not all of them are effective, how to select the effective configuration information.

[0156] The third priority rule also includes the configuration information of the first probe reference signal on different bandwidth portions, such as the priority between the configuration information of the first probe reference signal on the first bandwidth portion and the configuration information of the first probe reference signal on the second bandwidth portion. In one embodiment, the first bandwidth portion can be understood as the active bandwidth, for example, the configuration information of the first probe reference signal on the active bandwidth is higher than that of other bandwidth portions.

[0157] For example, the configuration information of the probe reference signal on the first aggregated carrier has the highest priority; or

[0158] The highest priority is given to the media access channel control unit's update configuration information for any carrier list; or

[0159] The configuration information for the activated bandwidth portion has the highest priority; or

[0160] The configuration information of the cell with the earliest carrier sequence number has the highest priority; or

[0161] The configuration information of the bandwidth segment with the largest bandwidth is given the highest priority.

[0162] In some embodiments of this application, determining the transmission power of the probe reference signal includes one or more of the following:

[0163] Based on the fifth priority rule, determine the power configuration information of the detection reference signal;

[0164] Based on the power control command, determine the power adjustment information of the probe reference signal;

[0165] The transmission power of the detection reference signal is determined based on the number of the first carrier waves.

[0166] The transmission power of the detection reference signal is determined based on the number of target carriers;

[0167] Determine the transmission power of the probe reference signal based on the bandwidth of the target carrier;

[0168] The first carrier includes at least one of the following:

[0169] All carriers or a portion of carriers among N target carriers;

[0170] The target carrier activated by the downlink control information or media access channel control unit;

[0171] The target carrier is selected according to preset rules.

[0172] In one possible embodiment, the transmission power of the probe reference signal is determined according to the first unit.

[0173] In this embodiment, the power configuration information of the probe reference signal can be determined according to the fifth priority rule. Alternatively, the power configuration information of the probe reference signal can be determined according to the fifth priority rule. Alternatively, the power adjustment information of the probe reference signal can be directly determined according to a power control command. Alternatively, the transmission power of the probe reference signal can be determined according to the number of carriers. Alternatively, the transmission power of the probe reference signal can be determined according to the carrier bandwidth of the second carrier.

[0174] The fifth priority rule can be the same priority rule as the third priority rule mentioned above.

[0175] It is understood that the probe reference signal includes a first probe reference signal and a second probe reference signal. That is, the power configuration information of the first probe reference signal can be determined according to the fifth priority rule, and the power configuration information of the second probe reference signal can also be determined according to the fifth priority rule. Furthermore, the power adjustment information of the second probe reference signal can be directly determined according to a power control command. The transmission power of the second probe reference signal can also be determined based on the number of carriers. Finally, the transmission power of the second probe reference signal can be determined based on the carrier bandwidth of the second carrier.

[0176] The first carrier includes all or part of the N target carriers, or the target carrier activated by downlink control information (DCI) or media access channel control unit (MAC CE), or the target carrier selected according to preset rules.

[0177] It is worth noting that if the detection reference signal includes a first detection reference signal, the first detection reference signal is transmitted on multiple target carriers, and the transmission power can be determined on each target carrier according to the same rule. Therefore, in this case, the transmission power is the transmission power of the detection reference signal on the multiple target carriers respectively; alternatively, the multiple target carriers can be regarded as a first unit, and unified power control can be performed on the first unit. Therefore, in this case, the transmission power is the transmission power of the detection reference signal on the first unit.

[0178] In some embodiments of this application, the detection reference signal bandwidth includes at least one of the following:

[0179] The bandwidth used for transmitting the first probe reference signal and / or the second probe reference signal on N target carriers; the bandwidth used for transmitting the probe reference signal in the first carrier; the bandwidth used for transmitting the probe reference signal on any carrier; and the bandwidth used for transmitting the probe reference signal in the first unit.

[0180] In this embodiment, the probe reference signal bandwidth is the bandwidth used to transmit the probe reference signal. Specifically, the probe reference signal bandwidth includes the bandwidth used to transmit at least one of the first probe reference signal and the second probe reference signal on N target carriers, and also includes the bandwidth used to transmit the probe reference signal on one or more first carriers. It can also be the bandwidth used to transmit the probe reference unit on any carrier. Any carrier can be a target carrier or a second carrier.

[0181] In some embodiments of this application, determining the transmission power of the probe reference signal includes one or more of the following:

[0182] Based on the bandwidth of the detection reference signal, determine the transmission power of the first detection reference signal and / or the transmission power of the second detection reference signal;

[0183] The transmission power of the first detection reference signal on the first carrier is allocated according to the ratio of the bandwidth of any first carrier in the first unit to the bandwidth of the first unit.

[0184] Based on the ratio of the bandwidth of any first carrier used to transmit the probe reference signal in the first unit to the bandwidth of the first unit used to transmit the probe reference signal, the transmission power of the first probe reference signal on any first carrier is allocated.

[0185] The first unit includes at least two target carriers, or the first unit includes at least two first carriers, wherein the first carriers are carriers configured with aggregation indication.

[0186] In this embodiment, the transmission power of the first detection reference signal can be determined based on the bandwidth of the detection reference signal, and the transmission power of the second detection reference signal can also be determined. Wherein, when the transmission power of the first detection reference signal and the total transmission power of the second detection reference signal exceed a power threshold, the first detection reference signal is prioritized to be configured with a higher transmission power. It is worth noting that "based on the bandwidth of the detection reference signal" can be understood as the bandwidth of the detection reference signal on one carrier, the total bandwidth on multiple carriers, or the bandwidth of the first unit.

[0187] The transmission power of the first detection reference signal transmitted on the first carrier can also be allocated according to the ratio of the bandwidth of any one of the first carriers in the bandwidth of the first unit. The first unit includes at least two target carriers, or at least two first carriers configured with aggregation indication. The bandwidth of the first unit can be the total bandwidth of all carriers in the first unit, or the sum of the bandwidths of some carriers in the first unit.

[0188] The transmission power of the first probe reference signal transmitted on the first carrier can also be allocated according to the ratio of the bandwidth of any first carrier used for transmitting the probe reference signal in the first unit to the bandwidth of the first unit used for transmitting the probe reference signal. The bandwidth of the first unit used for transmitting the probe reference signal can be the total bandwidth of the first unit used for transmitting the probe reference signal, or the sum of the bandwidths of some carriers in the first unit used for transmitting the probe reference signal.

[0189] Specifically, for example, the transmission power can be determined based on the detection reference signal type of the carrier of the aperiodic detection reference signal type; or

[0190] The transmit power is determined based on the carrier's probe reference signal type; or

[0191] The transmission power is determined by the type of detection reference signal of the main cell; or

[0192] The transmit power is determined by the type of probe reference signal configured in the aggregated carrier group; or

[0193] The transmit power is determined based on the power control type of the carrier of the aperiodic detection reference signal type; or

[0194] The transmit power is determined based on the power control type of the carrier of the aggregation detection reference signal type; or

[0195] The transmit power is determined by the power control type of the primary cell; or

[0196] The transmit power is determined by the power control type configured in the aggregated carrier group.

[0197] In some embodiments of this application, the transmission power of the first detection reference signal and / or the second detection reference signal is determined by the following formula:

[0198] P O_SRS,b, (q s )+10log 10 (2 μ ·M SRS,b, (i))+α SRS,b, (q s )·PL b, (q d )--------(1)

[0199] Where, q s To detect the reference signal, q d denoted as path loss signal, b as the first bandwidth portion used to transmit the probe reference signal, c as the serving cell or camped cell, f as the carrier, μ as the subcarrier configuration, α as the power adjustment factor, PL as the path loss value, P0 as the expected received power value, and M as the bandwidth of the probe reference signal.

[0200] It is worth noting that, in the case of the first carrier, b can be understood as the first unit, and M can be understood as the bandwidth of the first unit; or, b can be a set of multiple BWPs, and M can be the bandwidth corresponding to the set of multiple BWPs.

[0201] In this embodiment, the transmission power of the probe reference signal can be determined using the above formula (1). Further, it can be first determined whether the total power of the probe reference signal exceeds the maximum power threshold.

[0202] The total power of the probe reference signal can be calculated using the following formula:

[0203] P O_SRS,b, (q s )+α SRS,b, (q s )·PL b, (q d )---------(2)

[0204] Where, q s To detect the reference signal, q d denoted as path loss signal, b as the first bandwidth portion used to transmit the detection reference signal, α as the power adjustment coefficient, PL as the path loss value, and P0 as the expected received power value.

[0205] It is worth noting that in the above embodiments, b can be understood as the first unit, and M can be understood as the bandwidth of the first unit; or b can be a set of multiple BWPs, and M can be the bandwidth corresponding to the set of multiple BWPs.

[0206] If the total power of the probe reference signals does not exceed the maximum power threshold, the transmission power of each probe reference signal is calculated using formula (1). If it does exceed the threshold, the transmission power of the probe reference signals is adjusted and allocated according to priority or configuration information.

[0207] In some embodiments of this application, the step of determining the spatial relationship of the detection reference signal includes:

[0275] In some embodiments of this application, the first detection reference signal is a third detection reference signal. The third detection reference signal is mapped onto W target carriers, or the third detection reference signal is a signal that maps a ZC sequence onto W target carriers.

[0276] When determining the transmission of the third detection reference signal, the transmission method, transmission power, and spatial relationship of multiple third detection reference signals are uniformly configured.

[0277] Specifically, the transmission power of the third detection reference signal can be determined according to the first priority rule, the transmission mode of the third detection reference signal can be determined according to the second priority rule, the priority of the configuration information of the third detection reference signal can be determined according to the third priority rule, and the spatial relationship of the third detection reference signal can be determined according to the fourth priority rule.

[0278] Specifically, when determining the transmission mode of the third detection reference signal, the transmission mode can be determined based on downlink control information. Alternatively, the transmission mode of the third detection reference signal on W target carriers can be determined based on the type of the third detection reference signal, or based on aggregation indication. Furthermore, the transmission mode of the third detection reference signal on W target carriers can be determined based on carrier aggregation parameters or the parameters of the first carrier configured with aggregation indication.

[0279] When determining the transmission method of the third probe reference signal according to the second priority rule, multiple third probe reference signals may be transmitted in the first preset order, or one third probe reference signal may be transmitted on a portion of the N target carriers in the second preset order, or one third probe reference signal may be transmitted on the carrier of the first unit in the third preset order.

[0280] In some feasible implementations, the transmission of the third probe reference signal is activated in accordance with the manner specified in the downlink control information, or the target carrier of the third probe reference signal is activated in accordance with the manner specified in the downlink control information.

[0281] The configuration priority of the third detection reference signal can be determined according to the third priority rule.

[0284] Furthermore, the spatial relationship of the third detection reference signal can be uniformly configured based on one or more of the following: the sixth priority rule, spatial relationship-related configuration information, the third priority rule, aggregation indication, downlink control information, detection reference signal type, and carrier aggregation parameters.

[0285] In some embodiments of this application, the first detection reference signal includes W fourth detection reference signals, where W is an integer greater than or equal to 2, and the N second detection reference signals have the same transmission time domain position or have overlapping symbols.

[0286] When determining the transmission of the fourth detection reference signal, the transmission method, transmission power, and spatial relationship of multiple third detection reference signals are uniformly configured.

[0287] Specifically, the transmission power of the fourth detection reference signal can be determined according to the first priority rule, the transmission mode of the fourth detection reference signal can be determined according to the second priority rule, the priority of the configuration information of the fourth detection reference signal can be determined according to the third priority rule, and the spatial relationship of the fourth detection reference signal can be determined according to the fourth priority rule.

[0288] Specifically, when determining the transmission mode of the fourth detection reference signal, the transmission mode can be determined based on downlink control information. Alternatively, the transmission mode of the fourth detection reference signal on W target carriers can be determined based on the type of the fourth detection reference signal, or based on aggregation indication. Furthermore, the transmission mode of the fourth detection reference signal on W target carriers can be determined based on carrier aggregation parameters or the parameters of the first carrier configured with aggregation indication.

[0289] When determining the transmission method of the fourth detection reference signal according to the second priority rule, multiple fourth detection reference signals may be transmitted in the first preset order, or one fourth detection reference signal may be transmitted on a portion of the N target carriers in the second preset order, or one fourth detection reference signal may be transmitted on the carrier of the first unit in the third preset order.

[0290] In some feasible implementations, the transmission of the fourth probe reference signal is activated in accordance with the manner specified in the downlink control information, or the target carrier of the fourth probe reference signal is activated in accordance with the manner specified in the downlink control information.

[0291] The configuration priority of the fourth detection reference signal can be determined according to the third priority rule.

[0292] For example, when determining the transmission power of the fourth probe reference signal, the power configuration information of the fourth probe reference signal can be determined according to the fifth priority rule; the power adjustment information of the fourth probe reference signal can be determined according to the power control command; the transmission power of the fourth probe reference signal can be determined according to the number of the first carriers; the transmission power of the fourth probe reference signal can be determined according to the number of target carriers; and the transmission power of the fourth probe reference signal can be determined according to the bandwidth of the target carriers.

[0293] When determining the transmission power of the fourth detection reference signal, the transmission power of the fourth detection reference signal can be determined based on the bandwidth of the detection reference signal, or the transmission power of the first detection reference signal on the third carrier can be allocated based on the ratio of the bandwidth of any third carrier in the first unit to the bandwidth of the first unit, or the transmission power of the fourth detection reference signal on any first carrier can be allocated based on the ratio of the bandwidth of any first carrier in the first unit used to transmit the fourth detection reference signal to the bandwidth of the first unit used to transmit the detection reference signal.

[0294] Furthermore, the spatial relationship of the fourth detection reference signal can be uniformly configured based on one or more of the following: the sixth priority rule, spatial relationship-related configuration information, the third priority rule, aggregation indication, downlink control information, detection reference signal type, and carrier aggregation parameters.

[0295] In some embodiments of this application, a method for receiving positioning signals is provided. Figure 4 A flowchart of a method for receiving location signals according to an embodiment of this application is shown. This method is applied to a network-side device, such as... Figure 4 As shown, the method includes:

[0296] Step 402: Receive the positioning signal sent by the terminal. Wherein, when the probe reference signal is configured on N target carriers, the terminal determines the transmission of the probe reference signal based on one or more of the following information: aggregation indication, carrier identifier or number of carriers, priority rule, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0297] Where N is an integer greater than or equal to 2.

[0298] In this embodiment, N carriers can be carriers of different frequency ranges, carriers of different cells, and carriers of different frequency layers, etc. In one possible embodiment, N carriers can also be understood as N cells, or N BWPs, etc. The terminal configures a probe reference signal on N target carriers, where N is an integer greater than or equal to 2. The transmission of the configured probe reference signal can be determined by at least one of the following: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters. This determines the transmission mode, transmission power, and / or spatial relationship of the probe reference signal, such as independent transmission, aggregated transmission, etc.

[0299] This application can effectively standardize the transmission of different types of carriers and different types of probe reference signals, realize the aggregation transmission and / or aggregation measurement of probe reference signals, and can simultaneously activate probe reference signals on multiple carriers for aggregation transmission and / or measurement, thereby improving the positioning speed and positioning accuracy of the terminal.

[0300] The carrier aggregation parameters include: time offset parameters (such as frame offset parameter SFN0), carrier offset (CA-offset) parameters, power offset parameters, frequency offset parameters, phase offset parameters, and receive and transmit time difference offset parameters.

[0301] Carrier aggregation parameters also include configuration or auxiliary information for aggregating transmissions or aggregating measurements.

[0302] The power control types include one or more of the following:

[0304] The types of probe reference signals include one or more of the following:

[0305] Periodic detection reference signal, aperiodic detection reference signal, semi-static detection reference signal, aggregated detection reference signal (first detection reference signal), and non-aggregated detection reference signal (second detection reference signal);

[0306] The aggregated detection reference signal (first detection reference signal) includes one or more of the following:

[0307] Inter-band aggregation detection reference signal, intra-band aggregation detection reference signal, continuous aggregation detection reference signal, and discontinuous aggregation detection reference signal.

[0308] In some embodiments of this application, the probe reference signal has symbols that are the same or overlap in the transmission time domain on at least two carriers.

[0309] In the embodiments of this application, the probe reference signals have the same transmission time domain position or overlapping symbols on different carriers. Specifically, at least two carriers can be any two carriers from N first carriers, and can belong to different frequency ranges or different cells. That is, on any two carriers configured with probe reference signals, the probe reference signals have the same time domain position or overlapping symbols.

[0310] In some embodiments of this application, configuration information or information of N carriers is sent to the terminal. The target information includes at least one of the following: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0311] In this embodiment, when N target carriers are configured with probe reference signals, the network side sends configuration information to the terminal. This configuration information corresponds to the N target carriers and instructs the transmission (e.g., transmission method and transmission rules) of the N target carriers and their corresponding probe reference signals. It is worth noting that the terminal receives configuration information from the network side, which may be configuration information for some of the N target carriers, or partial configuration information for a portion of the N target carriers. For example, it may receive aggregation indication information for only M carriers, or adjust the configuration information for only C carriers. Alternatively, the terminal receives target information from the network-side device and determines the transmission (e.g., transmission method and transmission rules) of the probe reference signals based on one or more pieces of information in the target information.

[0312] The target information specifically includes: aggregation indication, carrier identifier or number of carriers, priority rules, downlink control information, probe reference signal bandwidth, power control type, probe reference signal type, and carrier aggregation parameters.

[0313] In some embodiments of this application, the N target carriers include a first carrier configured with aggregation indication and a second carrier not configured with aggregation indication; and / or the probe reference signal includes a first probe reference signal transmitted in aggregation and a second probe reference signal transmitted in non-aggregation.

[0314] In this embodiment, the N target carriers include carriers configured with aggregation indicators and carriers without aggregation indicators. The carriers configured with aggregation indicators are aggregated into a first carrier, and the carriers without aggregation indicators are the aforementioned second carriers.

[0315] Correspondingly, the probe reference signal may also include a first probe reference signal that is indicated for aggregate transmission, such as the first probe reference signal being aggregated and transmitted according to the corresponding aggregation indication. The probe reference signal may also include a second probe reference signal that is not indicated for aggregate transmission, that is, transmitted in a non-aggregated transmission manner.

[0316] The aggregation indication can be understood as any of the following: the N1 carriers are configured with relevant indication information, indicating that the N1 carriers can be aggregated or partially aggregated, and the N1 carriers can be understood as the first carrier; or, by aggregating a carrier group, which contains N2 carriers, the N2 carriers can also be understood as the first carrier; or, for example, a cross-carrier probe reference signal is configured, and the carrier transmitted by the probe reference signal is the first carrier.

[0317] The aggregated transmission can be understood as the transmission of a probe reference signal on N3 carriers, where the probe reference signal is the first probe reference signal; it can also be understood as the transmission of a probe reference signal mapped onto N4 carriers, where the probe reference signal is the first probe reference signal; or it can be understood as the transmission of N5 probe reference signals on N6 carriers according to a specified rule, where the probe reference signal is the first probe reference signal.

[0318] In some embodiments of this application, a first detection reference signal is transmitted on a first carrier; and / or a second detection reference signal is transmitted on a second carrier.

[0319] In this embodiment, the first carrier is configured with an aggregation indication, and the first detection reference signal is transmitted by aggregation on the carriers of the first carrier. Alternatively, it can be split into multiple first carriers where the first detection reference signal is transmitted by aggregation. The first detection reference signal can be transmitted on all first carriers or on a subset of the first carriers.

[0320] The second probe reference signal, which is transmitted without aggregation, can be transmitted on a second carrier that is not configured with aggregation indication.

[0321] In some embodiments of this application, the method further includes:

[0322] Send configuration information for the probe reference signal to the terminal. The configuration information for the probe reference signal includes one or more of the following:

[0323] The information includes: probe reference signal configuration information, probe reference signal configuration update configuration information, carrier configuration information, configuration information of the first carrier configured with aggregation indication, and first probe reference signal configuration information.

[0324] In this embodiment of the application, the terminal receives configuration information of the probe reference signal sent by the network-side device. Through this configuration information, the terminal can obtain settings such as the transmission power, transmission order, transmission resources (such as transmission carrier, time domain information, frequency domain information, etc.), transmission priority, and spatial relationship of the probe reference signal.

[0325] The time-domain information includes one or more of the following: time slot offset, symbol offset, period value set, silence parameter set, repetition index set, frequency domain offset, and comb size.

[0326] The frequency domain information includes one or more of the following: frequency layer information, carrier information, bandwidth part (BWP) information, starting resource position in the physical resource block (PRB), and bandwidth in the PRB.

[0327] Specifically, the configuration information of the probe reference signal includes one or more of the following: probe reference signal configuration information, probe reference signal configuration update information, carrier configuration information, configuration information of the first carrier configured with aggregation indication, and configuration information of the first probe reference signal. The probe reference signal configuration information is used to directly configure the probe reference signal. The probe reference signal configuration update information is used to update the configuration information of the probe reference signal. The carrier configuration information is used to directly configure the carrier and / or the signals on the carrier. The configuration information of the first carrier configured with aggregation indication can configure all or some of the first carriers, or configure all or some of the signals in the first carrier. The configuration information of the first probe reference signal is used to configure the aggregated first probe reference signal separately or uniformly.

[0328] In some embodiments of this application, the aggregation indicator is the configuration information or indication information of the first unit; or

[0329] The aggregation indicator is the configuration information or indication information of the first unit; or

[0330] The aggregation indication is the configuration information or indication information of the first detection reference signal;

[0331] The first unit includes at least two target carriers, or the first unit includes at least two first carriers.

[0332] In the embodiments of this application, the aggregation indication can be used as configuration information or indication information for the first carrier, that is, the aggregation indication can be used to configure or indicate all or part of the first carrier.

[0333] The aggregation indication can also be the configuration information of the first unit, wherein the first unit includes at least two target carriers or first carriers. That is, the aggregation indication configures or indicates several target carriers in the first unit, or configures or indicates several first carriers in the first unit, or indicates the overall configuration or control of carriers or signals in the first unit.

[0334] The aggregation indicator can also serve as configuration or indication information for the first probe signal, i.e., the aggregation indicator can be used to configure or indicate the first probe reference signal transmitted via aggregation.

[0335] The aggregation indication is included in the configuration information or indication information of the first carrier; or;

[0336] The aggregation instruction is included in the configuration information or instruction information of the first unit; or;

[0337] The aggregation indication is included in the configuration information or indication information of the first detection reference signal.

[0338] In some embodiments of this application, the terminal determines the transmission of the probe reference signal, including one or more of the following:

[0339] Determine the method for transmitting the detection reference signal;

[0340] Determine the transmission power of the detection reference signal;

[0341] Determine the spatial relationship of the detection reference signal.

[0342] In this embodiment, determining the transmission of the probe reference signal specifically refers to determining the transmission method, transmission power, and spatial relationship of the probe reference signal during transmission. Specifically, the transmission method includes aggregated transmission, non-aggregated transmission, and the order or priority of transmission. The transmission power is specific to the transmission power of each or every probe reference signal. It is worth noting that the transmission method, transmission power, and spatial relationship of the first probe reference signal in aggregated transmission are important aspects of this application. Through effective control, the first probe reference signal can better assist in position measurement, achieving higher positioning accuracy. Since the total power used by the terminal to transmit the probe reference signal is fixed, the transmission power of some probe reference signals can be configured based on parameters such as the priority and carrier bandwidth ratio of different probe reference signals. Determining the transmission of the probe reference signal also includes determining the spatial relationship of the probe reference signals, where the spatial relationships of multiple probe reference signals can be consistent or inconsistent. In one possible embodiment, all first carriers, or first units, or first probe reference signals are determined to have the same transmission method, the same priority, uniformly scheduled transmission power, and configured spatial relationships, among at least one of these.

[0343] In some embodiments of this application, determining the transmission of the probe reference signal according to priority rules includes one or more of the following:

[0344] The transmission power of the detection reference signal is determined according to the first priority rule;

[0345] The transmission method of the detection reference signal is determined according to the second priority rule;

[0346] The priority of the configuration information for the probe reference signal is indicated according to the third priority rule;

[0347] The spatial relationship of the probe reference signal is determined according to the fourth priority rule.

[0348] In this embodiment, the transmission power of different detection reference signals is allocated according to a first priority rule. It is understood that the transmission power of detection reference signals with higher priority is given priority consideration.

[0349] The second priority rule indicates the transmission method and order of different probe reference signals. It is understandable that probe reference signals with higher priority are guaranteed to be transmitted first; for example, aggregated probe reference signals or the first probe reference signal can be transmitted first.

[0350] The actual configuration information used to transmit the probe reference signal is determined according to the third priority rule. It can be understood that, generally, one or more probe reference signals are configured according to the configuration information of the probe reference signal with the highest priority. In one embodiment, if multiple first carriers or first units are configured with different configuration information, the configuration information used to transmit the probe reference signal is determined according to the priority or the third priority rule. For example, when multiple probe reference signals are aggregated into a first probe reference signal, and the configuration information of the multiple probe reference signals is different, the configuration information of the first probe reference signal is determined according to the priority or the third priority rule.

[0351] The spatial relationships of multiple probe reference signals are configured according to the fourth priority rule. It is understood that priority is given to ensuring the successful configuration of the spatial relationships of probe reference signals with higher priority. Alternatively, it can be understood that multiple probe reference signals transmitted simultaneously or overlappingly, or probe reference signals on multiple carriers, have different spatial relationships, which are determined according to priority or the fourth priority rule. In one embodiment, three probe reference signals are configured with spatial relationships 1, 2, and 3, respectively. However, the terminal can only transmit the probe reference signals according to one or two spatial relationships simultaneously within a certain time period. The terminal can transmit only one or two probe reference signals corresponding to the spatial relationships according to priority or the fourth priority rule, or it can transmit all probe reference signals according to the highest priority spatial relationship.

[0352] The first, second, third, and fourth priority rules can be priority rules defined by a protocol. The protocol can specify at least one of the priorities A, B, C, and D, or it can specify the order of the priorities of events A, B, C, and D. A, B, C, and D are merely descriptive examples, and there may be more or fewer events.

[0353] In some embodiments of this application, the first priority rule includes one or more of the following:

[0354] Power allocation priority for the target carrier;

[0355] Power allocation priority for the probe reference signal;

[0356] The power allocation priority for the third carrier of the probe reference signal is not configured;

[0357] Power allocation priority for N target carriers and the third carrier;

[0358] Power allocation priority for other signals or channels; where other signals or channels are signals or channels different from the detection reference signal;

[0359] The power allocation priority for the first probe reference signal and other signals or channels.

[0360] In the embodiments of this application, the first priority rule includes the power allocation priority of the target carrier, that is, determining the priority order of one or more target carriers among multiple target carriers. It can be understood that the transmission power of the target carrier with higher priority is prioritized to be configured.

[0361] The first priority rule also includes the power allocation priority of multiple probe reference signals, that is, determining the priority order of one or more probe reference signals or carriers among multiple probe reference signals or multiple carriers corresponding to probe reference signals. It can be understood that priority is given to ensuring that the transmission power of probe reference signals or their corresponding carriers with higher priority is configured.

[0362] The first priority rule also includes the power allocation priority of the third carrier without a probe reference signal, that is, determining the priority order of one or more third carriers. It should be understood that the transmission power of the third carrier is determined according to the priority or the first priority rule, or the transmission power of the target carrier and the priority of the power allocation of the third carrier are determined.

[0363] The first priority rule also includes the power allocation priority of other signals or channels, which are signals or channels different from the probe reference signal. It should be understood that the power allocation of these other signals or channels is determined according to priority or priority rules. This can also be understood as the transmission power of other signals or channels determined according to priority, while ensuring that the transmission power of the reference probe signal is configured. Furthermore, it can be understood as the priority of the transmission power of the probe reference signal and the power allocation of other signals or channels.

[0364] The first priority rule also includes the power allocation priority between the first sounding reference signal and other signals or channels. Specifically, the first sounding reference signal has a higher priority than other signals or channels. That is, when allocating power to the first sounding reference signal and other signals or channels, priority is given to ensuring that the transmission power of the first sounding reference signal is configured, and vice versa.

[0365] In some embodiments of this application, the N target carriers satisfy at least one of the following:

[0366] The N target carriers include primary cell carriers and secondary cell carriers;

[0367] The N target carriers include carriers located in the uplink and carriers that supplement the uplink;

[0368] The N target carriers include carriers with scheduled PUSCH and carriers without scheduled PUSCH.

[0369] Multiple probe reference signals on N target carriers include probe reference signals of different priorities; and / or

[0370] The detection reference signals on the N target carriers include the first detection reference signal and the second detection reference signal;

[0371] The detection reference signals on the N target carriers include detection reference signals used for positioning and detection reference signals not used for positioning.

[0372] The priority rule can be understood as A having a higher priority than B, or B having a higher priority than A, i.e., prioritizing the power allocation of A or B. A can be understood as at least one of the following: primary cell carrier, uplink carrier, carrier with scheduled PUSCH, first priority probe reference signal, first probe reference signal, probe reference signal used for positioning. B can be understood as at least one of the following: secondary cell carrier, supplementary uplink carrier, carrier without scheduled PUSCH, xth priority probe reference signal, second probe reference signal, probe reference signal not used for positioning. In this embodiment, the first priority rule also includes the power allocation priority of the third carrier and N target carriers, specifically including the power priority allocation between the third carrier and the N target carriers, the power priority allocation among multiple third carriers, and the power priority allocation among the N target carriers. The power priorities of the third carrier and the N target carriers are different, such as the power priority of the third carrier being higher or lower than the power priority of the N target carriers.

[0373] The first priority rule also includes the power allocation priority of the probe reference signal and / or the first signal. Specifically, it includes the power priority allocation among multiple probe reference signals, the power priority allocation between the probe reference signal and the first signal, and the power priority allocation among multiple first signals. The power allocation priorities of the probe reference signal and the first signal are different; for example, the priority of the probe reference signal may be higher or lower than the power allocation priority of the first signal.

[0374] The first signal is specifically a signal other than the detection reference signal, or another channel, such as PRACH, PUCCH, PUSCH, etc.

[0375] Furthermore, among the N target carriers, there are one or more of the following: primary cell carrier and secondary cell carrier, uplink carrier and supplementary uplink carrier, carrier with scheduled PUSCH and carrier without scheduled PUSCH. The probe reference signals on the target carriers include one or more of the following: probe reference signals of different priorities, the aforementioned first probe reference signal and the aforementioned second probe reference signal, probe reference signals used for positioning and probe reference signals not used for positioning.

[0376] In some implementations, when M target carriers are located in the same aggregated carrier group (or first unit), the target carriers in the same aggregated carrier group have the same power allocation priority.

[0377] In some embodiments of this application, the transmission power of the probe reference signal is determined according to a first priority rule, including one or more of the following:

[0378] Based on the received first priority indication information, determine the power allocation priority of N target carriers;

[0379] Based on the first priority indication information, determine the power allocation priority of the detection reference signal on the N target carriers.

[0380] In this embodiment of the application, the power allocation priority of N target carriers is determined based on the received first priority indication information associated with the first priority rule. The first priority rule can be a priority rule defined by a protocol, i.e., setting the power priority of the target carriers.

[0381] It can also determine the power allocation priority of the probe reference signals on N target carriers based on the received first priority indication information, that is, set the power priority of the probe reference signals on the target carriers. For example, the priority of the target carriers or the priority of the probe reference signals can be configured directly.

[0382] In some embodiments of this application, the method of determining the transmission of the detection reference signal includes one or more of the following:

[0383] Based on the downlink control information, determine the transmission method of the detection reference signal;

[0384] The transmission method of the detection reference signal on N target carriers is determined based on the type of detection reference signal;

[0385] Based on the aggregation instruction, determine the transmission method of the probe reference signal;

[0386] The transmission method of the detection reference signal for the target carrier is determined based on the carrier aggregation parameters or the parameters of the first carrier configured with aggregation indication.

[0387] In this embodiment, determining the transmission mode of the probe reference signal can be based on downlink control information (DCI), or on the type of the probe reference signal, such as aggregated, non-aggregated, periodic, or aperiodic. Alternatively, the transmission mode can be determined based on an aggregation indication, or on carrier aggregation parameters or parameters of a first carrier configured with an aggregation indication.

[0388] In some embodiments of this application, the second priority rule includes:

[0389] The transmission priority of multiple first detection reference signals; and / or

[0390] The transmission priority of the first detection reference signal and the second detection reference signal.

[0391] In this embodiment, the second priority rule includes the transmission priority of multiple first detection reference signals. It is understood that among the multiple first detection reference signals, the first detection reference signal with the higher priority is prioritized for transmission. The second priority rule also includes the transmission priority between the first detection reference signal and the second detection reference signal. For example, if the transmission priority of the first detection reference signal is higher than that of the second detection reference signal, then the first detection reference signal is prioritized for transmission.

[0392] In some embodiments of this application, the transmission method of the detection reference signal is determined according to the second priority rule, including one or more of the following:

[0393] Multiple first detection signals are sent in a pre-defined sequence.

[0394] According to the second predetermined order, a first detection reference signal is transmitted on a portion of the N target carriers;

[0395] According to the third predetermined sequence, a first detection reference signal is transmitted on the carrier of the first unit;

[0396] The first unit includes a plurality of first carriers or a plurality of target carriers configured with aggregation indication.

[0397] In the embodiments of this application, multiple first detection reference signals can be transmitted sequentially, in a polling manner, or selectively according to a first preset order. Alternatively, the transmission priority of one or more detection reference signals among the multiple first detection reference signals can be determined according to the first preset order.

[0398] Alternatively, a first probe reference signal can be transmitted on a subset of the N target carriers according to a second predetermined order. This means a first probe reference signal is transmitted on a subset of the N carriers. The transmission priority of a first probe reference signal on a carrier can also be determined according to this second predetermined order. In one embodiment, the second predetermined order is to select carriers with large aggregation bandwidth and transmit the first probe reference signal. In another embodiment, the second predetermined order is to select carriers that satisfy a specified aggregation rule and transmit the first probe reference signal. In yet another embodiment, the first probe reference signal is transmitted according to a second predetermined order related to the priority rule described above.

[0399] Alternatively, a first detection reference signal can be transmitted on the carrier of the first unit according to a third preset order. This can also be understood as transmitting on all or part of the carriers in the first unit according to a third preset order associated with the second priority. Alternatively, the priority of a first detection reference signal on all or part of the carriers in the first unit can be determined according to the third preset order.

[0400] The first detection reference signals in multiple first units can be sent sequentially according to the fourth preset order, and the sending priority of the first detection reference signals in multiple first units can be determined according to the fourth preset order.

[0401] The first unit includes multiple first carriers configured with aggregation indication, or the first unit includes multiple target carriers. The aggregation detection reference signal group includes a first setting order and a second setting order, the carrier configuration information includes a third setting order, and the configuration information of the first unit includes a fourth setting order. The first setting order, the second setting order, the third setting order, and the fourth setting order can be a protocol-defined setting order or a network configuration setting order.

[0402] In some embodiments of this application, the transmission mode of the detection reference signal is determined based on downlink control information, including one or more of the following:

[0403] Activate the transmission of the probe reference signal in accordance with the method specified in the downlink control information;

[0404] Activate the target carrier of the probe reference signal in accordance with the method specified in the downlink control information.

[0405] In this embodiment, the transmission of the probe reference signal and the carrier carrying the probe reference signal is determined according to the downlink control information (DCI). Specifically, this may include activating the transmission of one or more probe reference signals in a manner specified by the downlink control information (DCI). It may also involve activating the transmission of one or more target carriers of the first probe reference signal in a manner specified by the downlink control information (DCI). In one possible embodiment, the transmission of the first probe reference signal on all target carriers and the first carrier can be activated by a single downlink control command. If the first probe reference signal is composed of multiple probe reference signals aggregated together, the aggregated transmission of the multiple probe reference signals, i.e., the transmission of the first probe reference signal, can also be activated by a single downlink control information.

[0406] Specifically, the downlink control information (DCI) activates the simultaneous transmission of sounding reference signals on at least two carriers, or the downlink control information (DCI) activates the polling transmission of sounding reference signals on at least two carriers.

[0407] In some embodiments of this application, the third priority rule includes one or more of the following:

[0408] The priority of the configuration information of the first carrier and / or the configuration information of the second carrier;

[0409] Priority of configuration information for the first unit and / or other target carrier configuration information;

[0410] The priority of the configuration information of the first detection reference signal and / or the configuration information of the second detection reference signal;

[0411] The priority of the configuration information of the first configuration mode on the first detection reference signal and / or the configuration information of the second configuration mode on the first detection reference signal;

[0412] Priority of configuration information for multiple first detection reference signals;

[0413] The priority of the configuration information of the first probe reference signal on the first bandwidth portion and / or the configuration information of the first probe reference signal on the second bandwidth portion;

[0414] The first unit consists of multiple first carriers or multiple target carriers configured with aggregation indicators.

[0415] The configuration information of the first unit consists of configuration information for multiple first carriers or multiple target carriers configured with aggregation indications. In one embodiment, it can be understood that the carriers of the first unit use the same configuration information.

[0416] In this embodiment, the third priority rule can be the priority between the configuration information of the first carrier, the priority between the configuration information of the second carrier, or the priority between the configuration information of the first carrier and the configuration information of the second carrier. When the third priority rule is the priority between the configuration information of the first carrier and the configuration information of the second carrier, there is a priority relationship; for example, the priority of the configuration information of the first carrier is higher than the priority between the configuration information of the second carrier. In one possible embodiment, the probe reference signal is transmitted on multiple first carriers, but the configuration information of the first carriers is different, such as subcarriers, CP, u, etc. The configuration information of the carriers with lower priority is reconfigured or configured according to the configuration information of the carriers with higher priority.

[0417] The third priority rule may also include the priority of the configuration information of the first unit and / or the configuration information of other target carriers. Specifically, the first unit includes a first carrier or some target carriers configured with aggregation indication. The configuration information of the first unit may also correspond to the configuration information of the first carrier or target carrier according to the priority, or the priority among the configuration information of multiple first units or the priority of the configuration information of multiple other target carriers, or the priority of the configuration information of the first unit and other target carriers.

[0418] The third priority rule may also include the priority among the configuration information of multiple first detection reference signals, the priority among the configuration information of multiple second detection reference signals, and the priority between the configuration information of the first detection reference signal and the configuration information of the second detection reference signal.

[0419] The third priority rule may also include the priority of configuration information for different configuration methods on the first detection reference signal. These different configuration information may include the first configuration method, the second configuration method, and possibly the third, fourth, ..., Nth configuration method. This application does not limit this. For example, the configuration information of the MAC CE configuration can replace the configuration information of the RRC, meaning that the priority of the MAC CE configuration information is higher than that of the RRC configuration information.

[0420] The third priority rule can also include the priority of multiple configuration information for multiple first detection reference signals, where the multiple configuration information can be different. This can also be understood as: if multiple first detection reference signals are configured with different configuration information, and not all of them are effective, how to select the effective configuration information.

[0421] The third priority rule also includes the configuration information of the first probe reference signal on different bandwidth portions, such as the priority between the configuration information of the first probe reference signal on the first bandwidth portion and the configuration information of the first probe reference signal on the second bandwidth portion. In one embodiment, the first bandwidth portion can be understood as the active bandwidth, for example, the configuration information of the first probe reference signal on the active bandwidth is higher than that of other bandwidth portions.

[0422] For example, the configuration information of the probe reference signal on the first aggregated carrier has the highest priority; or

[0423] The highest priority is given to the media access channel control unit's update configuration information for any carrier list; or

[0424] The configuration information for the activated bandwidth portion has the highest priority; or

[0425] The configuration information of the cell with the earliest carrier sequence number has the highest priority; or

[0426] The configuration information of the bandwidth segment with the largest bandwidth is given the highest priority.

[0427] In some embodiments of this application, determining the transmission power of the probe reference signal includes one or more of the following:

[0428] Based on the fifth priority rule, determine the power configuration information of the detection reference signal;

[0429] Based on the power control command, determine the power adjustment information of the probe reference signal;

[0430] The transmission power of the detection reference signal is determined based on the number of the first carrier waves.

[0431] The transmission power of the detection reference signal is determined based on the number of target carriers;

[0432] The transmission power of the probe reference signal is determined based on the bandwidth of the target carrier.

[0433] The first carrier includes at least one of the following:

[0434] All carriers or a portion of carriers among N target carriers;

[0435] The target carrier activated by the downlink control information or media access channel control unit;

[0436] The target carrier is selected according to preset rules.

[0437] In one possible embodiment, the transmission power of the probe reference signal is determined according to the first unit.

[0438] In this embodiment, the power configuration information of the probe reference signal can be determined according to the fifth priority rule. Alternatively, the power configuration information of the probe reference signal can be determined according to the fifth priority rule. Alternatively, the power adjustment information of the probe reference signal can be directly determined according to a power control command. Alternatively, the transmission power of the probe reference signal can be determined according to the number of carriers. Alternatively, the transmission power of the probe reference signal can be determined according to the carrier bandwidth of the second carrier.

[0439] The fifth priority rule can be the same priority rule as the third priority rule mentioned above.

[0440] It is understood that the probe reference signal includes a first probe reference signal and a second probe reference signal. That is, the power configuration information of the first probe reference signal can be determined according to the fifth priority rule, and the power configuration information of the second probe reference signal can also be determined according to the fifth priority rule. Furthermore, the power adjustment information of the second probe reference signal can be directly determined according to a power control command. The transmission power of the second probe reference signal can also be determined based on the number of carriers. Finally, the transmission power of the second probe reference signal can be determined based on the carrier bandwidth of the second carrier.

[0441] The first carrier includes all or part of the N target carriers, or the target carrier activated by downlink control information (DCI) or media access channel control unit (MAC CE), or the target carrier selected according to preset rules.

[0442] It is worth noting that if the detection reference signal includes a first detection reference signal, the first detection reference signal is transmitted on multiple target carriers, and the transmission power can be determined on each target carrier according to the same rule. Therefore, in this case, the transmission power is the transmission power of the detection reference signal on the multiple target carriers respectively; alternatively, the multiple target carriers can be regarded as a first unit, and unified power control can be performed on the first unit. Therefore, in this case, the transmission power is the transmission power of the detection reference signal on the first unit.

[0443] In some embodiments of this application, the detection reference signal bandwidth includes at least one of the following:

[0444] The bandwidth on N target carriers used to transmit the first probe reference signal and / or the second probe reference signal;

[0445] The bandwidth used to transmit the probe reference signal in the first carrier wave;

[0446] The bandwidth used for transmitting the probe reference signal on any carrier, and the bandwidth used for transmitting the probe reference signal in the first unit.

[0447] In this embodiment, the probe reference signal bandwidth is the bandwidth used to transmit the probe reference signal. Specifically, the probe reference signal bandwidth includes the bandwidth used to transmit at least one of the first probe reference signal and the second probe reference signal on N target carriers, and also includes the bandwidth used to transmit the probe reference signal on one or more first carriers. It can also be the bandwidth used to transmit the probe reference unit on any carrier. Any carrier can be a target carrier or a second carrier.

[0448] In some embodiments of this application, determining the transmission power of the probe reference signal includes one or more of the following:

[0449] Based on the bandwidth of the detection reference signal, determine the transmission power of the first detection reference signal and / or the transmission power of the second detection reference signal;

[0450] The transmission power of the first detection reference signal on any first carrier is allocated according to the ratio of the bandwidth of any first carrier in the bandwidth of the first unit.

[0451] Based on the ratio of the bandwidth of the first carrier used to transmit the probe reference signal in the first unit to the bandwidth of the first unit used to transmit the probe reference signal, the transmission power of the first probe reference signal on any one of the first carriers is allocated.

[0452] The first unit includes at least two target carriers, or the first unit includes at least two first carriers, wherein the first carriers are carriers configured with aggregation indication.

[0453] In this embodiment, the transmission power of the first detection reference signal can be determined based on the bandwidth of the detection reference signal, and the transmission power of the second detection reference signal can also be determined. Wherein, when the transmission power of the first detection reference signal and the total transmission power of the second detection reference signal exceed a power threshold, the first detection reference signal is prioritized to be configured with a higher transmission power. It is worth noting that "based on the bandwidth of the detection reference signal" can be understood as the bandwidth of the detection reference signal on one carrier, the total bandwidth on multiple carriers, or the bandwidth of the first unit.

[0454] The transmission power of the first detection reference signal transmitted on the first carrier can also be allocated according to the ratio of the bandwidth of any one of the first carriers in the bandwidth of the first unit. The first unit includes at least two target carriers, or at least two first carriers configured with aggregation indication. The bandwidth of the first unit can be the total bandwidth of all carriers in the first unit, or the sum of the bandwidths of some carriers in the first unit.

[0455] The transmission power of the first probe reference signal transmitted on the first carrier can also be allocated according to the ratio of the bandwidth of any first carrier used for transmitting the probe reference signal in the first unit to the bandwidth of the first unit used for transmitting the probe reference signal. The bandwidth of the first unit used for transmitting the probe reference signal can be the total bandwidth of the first unit used for transmitting the probe reference signal, or the sum of the bandwidths of some carriers in the first unit used for transmitting the probe reference signal.

[0456] Specifically, for example, the transmission power can be determined based on the detection reference signal type of the carrier of the aperiodic detection reference signal type; or

[0457] The transmit power is determined based on the carrier's probe reference signal type; or

[0458] The transmission power is determined by the type of detection reference signal of the main cell; or

[0459] The transmit power is determined by the type of probe reference signal configured in the aggregated carrier group; or

[0460] The transmit power is determined based on the power control type of the carrier of the aperiodic detection reference signal type; or

[0461] The transmit power is determined based on the power control type of the carrier of the aggregation detection reference signal type; or

[0462] The transmit power is determined by the power control type of the primary cell; or

[0463] The transmit power is determined by the power control type configured in the aggregated carrier group.

[0464] In some embodiments of this application, determining the transmission power of the detection reference signal includes:

[0465] The transmission power of the first and / or second detection reference signals is determined using the following formula:

[0466] P O_SRS,b, (q s )+10log 10 (2 μ ·M SRS,b, (i))+α SRS,b, (q s )·PL b, (q d )--------(1)

[0468] It is worth noting that, in the case of the first carrier, b can be understood as the first unit, and M can be understood as the bandwidth of the first unit; or, b can be a set of multiple BWPs, and M can be the bandwidth corresponding to the set of multiple BWPs.

[0469] In this embodiment, the transmission power of the probe reference signal can be determined using the above formula (1). Further, it can be first determined whether the total power of the probe reference signal exceeds the maximum power threshold.

[0470] The total power of the probe reference signal can be calculated using the following formula:

[0471] P O_SRS,b, (q s )+α SRS,b, (q s )·PL b, (q d )---------(2)

[0472] Where, q s To detect the reference signal, q d denoted as path loss signal, b as the first bandwidth portion used to transmit the detection reference signal, α as the power adjustment coefficient, PL as the path loss value, and P0 as the expected received power value.

[0473] It is worth noting that in the above embodiments, b can be understood as the first unit, and M can be understood as the bandwidth of the first unit; or b can be a set of multiple BWPs, and M can be the bandwidth corresponding to the set of multiple BWPs.

[0474] If the total power of the probe reference signals does not exceed the maximum power threshold, the transmission power of each probe reference signal is calculated using formula (1). If it does exceed the threshold, the transmission power of the probe reference signals is adjusted and allocated according to priority or configuration information.

[0475] In some embodiments of this application, the step of determining the spatial relationship of the detection reference signal includes:
