[0036] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0037] The communication method of the embodiment of the present disclosure can be applied to Figure 1 In the wireless communication system shown in FIG. Figure 1 As shown in FIG, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device via wireless resources and performs data transmission.

[0038] It is understandable that Figure 1 The wireless communication system shown is only for schematic illustration. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices. Figure 1 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0039] It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network. 5G network can also be called new radio (NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as simply a network.

[0040] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices or core network devices. The wireless access network device may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​an NR system, or it may also be a component or part of a base station. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device.

[0041] In some embodiments, the core network device may include a location management function (LMF) network element. Optionally, the LMF network element includes a location server, which may be implemented as any one of the following: a location management function (LMF), an enhanced serving mobile location center (E-SMLC), a secure user plane location (SUPL), or a secure user plane location platform (SUPL LP).

[0042] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), customer premises equipment (Customer Premise Equipment, CPE), pocket computers (Pocket Personal Computers, PPCs), handheld computers, personal digital assistants (Personal Digital Assistants, PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0043] In some embodiments of the present disclosure, to reduce positioning latency, PPWs are introduced when there are no measurement gaps. This allows the terminal to perform PRS measurements within a time window outside of the measurement gap. PPWs are typically configured on a per-cell basis and activated on a per-cell, per-window basis.

[0044] In some embodiments of the present disclosure, each PPW can be configured with the following parameters: a PPW identity document (ID), the PPW period and starting timeslot position, the PPW length, and the PPW type. The PPW length refers to the duration of the PPW, i.e., the number of time slots. The PPW type indicates whether, when a terminal performs a PRS measurement within this PPW, it affects the transmission of other downlink channels or signals on a single component carrier or multiple component carriers, and whether it affects the transmission of other downlink channels or signals on the symbol containing the PRS or the symbol containing the PPW.

[0045] PPW types include Type 1A, Type 1B, and Type 2. If the PPW type is Type 1A and indicates a high PRS priority, the PRS takes precedence over downlink channels or signals on all symbols within the PPW. If the PPW type is Type 1B and indicates a high PRS priority, the PRS takes precedence over downlink channels or signals on a terminal-specified frequency band. For example, the terminal-specified frequency band may be the frequency band where the PRS resides. If the PPW type is Type 2 and indicates a high PRS priority, the PRS takes precedence only over downlink channels or signals on symbols where the PRS resides. If the PRS priority is high, the PRS is received; otherwise, the PRS is not received.

[0046] The downlink channels or signals may include the Physical Downlink Control Channel (PDCCH), the Physical Downlink Shared Channel (PDSCH), the Demodulation Reference Signal (DMRS), and the Channel State Information-Reference Signal (CSI-RS). The priority parameter of the PPW may further indicate the priority between the PRS and the PDCCH / PDSCH / CSI-RS.

[0047] In the first state State 1, the priority of PRS can be higher than the priority of all downlink channels or signals except the synchronization signal / physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB), and the downlink channel or signal can be PDCCH, PDSCH, DMRS or CSI-RS. In the second state State 2, the priority of PRS can be lower than PDCCH and PDSCH corresponding to Ultra-Reliable and Low Latency Communications (URLLC), and higher than other downlink channels or signals except SSB. Among them, the PDSCH corresponding to URLLC refers to the PDSCH scheduled based on DCI format 1_1 or 1_2 when the priority indication field in the downlink control information (DCI) format is set to 1. In the third state State 3, the priority of PRS can be lower than all downlink channels or signals except SSB.

[0048] In some embodiments of the present disclosure, to improve the accuracy of time-based positioning methods, bandwidth aggregation can be used to transmit PRS or Sounding Reference Signals (SRS). When bandwidth aggregation is used to transmit PRS, i.e., multiple CCs are used to transmit PRS simultaneously, the issue of configuring the PPW becomes a challenge.

[0049] In view of this, an embodiment of the present disclosure provides a communication method, which receives at least one indication information, where the at least one indication information is used to indicate the PPWs of multiple CCs that simultaneously transmit PRS, thereby realizing the configuration of each PPW when multiple CCs simultaneously transmit PRS under bandwidth aggregation, thereby improving the accuracy of terminal positioning based on carrier aggregation.

[0050] In the embodiment of the present disclosure, it can be further configured that, among different CCs of the multiple CCs used for simultaneously transmitting PRS, at least one BWP includes at least one PPW with the same PPW parameters, so that when PRS is simultaneously transmitted based on multiple CCs under bandwidth aggregation, the measurement of PRS on multiple CCs can be achieved by activating the same PPW parameters on the BWP with the same PPW parameters in each CC, so as to ensure that PRS transmitted at the same symbol position, or time domain position, on different CCs is measured at the same PPW time instance.

[0051] Figure 2FIG. 1 is a flow chart showing a communication method according to an exemplary embodiment. Figure 2 As shown, the communication method is executed by the terminal and includes the following steps.

[0052] In step S11, at least one indication information is received.

[0053] The indication information is used to indicate the PPW of the BWP included in each CC in the multiple CCs. The multiple CCs are used to transmit PRSs simultaneously.

[0054] In an embodiment of the present disclosure, a terminal may receive at least one indication message sent by a network device, where the at least one indication message is used to indicate the PPW of the BWP included in each of multiple CCs. Furthermore, the multiple CCs are used to simultaneously transmit PRSs. In other words, PRSs may be simultaneously transmitted using a bandwidth aggregation method based on the BWPs in the multiple CCs. The PPW is used to configure the time during which the terminal measures PRSs. The PPW may be pre-configured by the network device and activated or deactivated by the network device via downlink messages. Furthermore, the PPW may also include PRS processing time, meaning that the terminal may also perform PRS measurement processing within the PPW.

[0055] Using the bandwidth aggregation method to send PRS can be to activate a BWP on each of multiple CCs and simultaneously send PRS based on the activated BWPs in a carrier aggregation manner. The network device can pre-configure a PPW list for each BWP through Radio Resource Control (RRC) signaling, and each PPW list includes at least one PPW. When sending PRS based on the activated BWPs in a carrier aggregation manner, the network device can further activate a PPW in the PPW list of each BWP so that the terminal can measure PRS in the PPW.

[0056] In the disclosed embodiments, the indication information may be carried in the RRC. The PPW on at least one BWP included in each of the multiple CCs is configured via RRC signaling, and the PPW of the BWP included in each CC in the multiple CCs is indicated to the terminal, thereby enabling the configuration of the PPW corresponding to the PRS when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation.

[0057] By adopting the technical solution of the embodiment of the present disclosure, by receiving at least one indication information, which is used to indicate the PPWs of multiple CCs that simultaneously transmit PRS, the configuration of each PPW is realized when multiple CCs simultaneously transmit PRS under bandwidth aggregation, thereby improving the accuracy of the terminal's positioning based on carrier aggregation.

[0058] In an embodiment of the present disclosure, each of the multiple CCs may include a reference BWP, where the reference BWP is the BWP used to perform carrier aggregation on the multiple CCs to simultaneously transmit PRS. The reference BWPs of different CCs have at least one identical reference PPW, where the reference PPW is a PPW that includes reference PPW parameters.

[0059] In the embodiment of the present disclosure, each of the multiple CCs may include at least one BWP, and at least one BWP included in each of the multiple CCs may be a reference BWP. The reference BWPs on different CCs may correspond to different BWP IDs, bandwidths, and the like.

[0060] When bandwidth aggregation is used to simultaneously transmit PRSs across multiple CCs, the BWP activated for aggregation in each CC serves as the reference BWP. Furthermore, other BWPs in each CC may or may not be reference BWPs. Reference BWPs in different CCs share at least one common reference PPW, which is a PPW that includes reference PPW parameters.

[0061] In the embodiment of the present disclosure, it may be configured that the BWPs included in each CC in a plurality of CCs include at least one reference BWP.

[0062] In one example, if multiple CCs are CC#1, CC#2, and CC#3, CC#1 includes BWP#1 and BWP#4, CC#2 includes BWP#2 and BWP#5, and CC#3 includes BWP#3 and BWP#6, BWP#1 of CC#1, BWP#2 of CC#2, and BWP#3 of CC#3 can all be set as reference BWPs. That is, BWP#1, BWP#2, and BWP#3 are set to have at least one identical reference PPW. In other words, the PPW list configured by the network device for BWP#1, the PPW list configured for BWP#2, and the PPW list configured for BWP#3 each include at least one identical reference PPW, and the reference PPWs include identical reference PPW parameters.

[0063] Furthermore, the remaining PPWs in the PPW list configured for BWP#1, the PPW list configured for BWP#2, and the PPW list configured for BWP#3 may or may not be reference PPWs. Furthermore, the PPWs in BWP#4 of CC#1, BWP#5 of CC#2, and BWP#6 of CC#3 may or may not be reference PPWs. If the PPWs in BWP#4, BWP#5, and BWP#6 are not reference PPWs, when PRS is transmitted via carrier aggregation based on CC#1, CC#2, and CC#3, only BWP#1 of CC#1, BWP#2 of CC#2, and BWP#3 of CC#3 can be activated for aggregation to ensure that the PPWs of CC#1, CC#2, and CC#3 are consistent. This ensures that the terminal can measure PRS transmitted at the same symbol position, or time domain position, on different CCs within the same PPW time.

[0064] Those skilled in the art will appreciate that the above description is merely illustrative. In practice, BWP#4 of CC#1, BWP#5 of CC#2, and BWP#6 of CC#3 may each include at least one identical reference PPW, while BWP#1 of CC#1, BWP#2 of CC#2, and each PPW in CC#3 may or may not be a reference PPW. This is analogous and will not be further described here.

[0065] In the embodiment of the present disclosure, it may also be set that all BWPs included in each CC among multiple CCs are reference BWPs, that is, all BWPs included in each CC include at least one identical reference PPW.

[0066] In one example, if multiple CCs are CC#1, CC#2, and CC#3, each of which includes one or more BWPs, all BWPs included in CC#1, CC#2, and CC#3 can be set as reference BWPs, that is, all BWPs included in CC#1, CC#2, and CC#3 can be set to include at least one identical reference PPW. In this case, when PRS is transmitted via carrier aggregation based on CC#1, CC#2, and CC#3, any BWP in CC#1, any BWP in CC#2, and any BWP in CC#3 can be activated for aggregation, ensuring that the PPWs of CC#1, CC#2, and CC#3 are consistent. This ensures that the terminal can measure PRSs transmitted at the same symbol position, or time domain position, on different CCs within the same PPW time. Furthermore, those skilled in the art will appreciate that other PPWs in each BWP may or may not be reference PPWs.

[0067] In the embodiment of the present disclosure, the PPW parameter may include at least one of the following:

[0068] PPW identification ID;

[0069] PPW entry in the PPW list;

[0070] The temporal location of the PPW;

[0071] PPW length;

[0072] PPW type;

[0073] PPW priority.

[0074] Each PPW parameter can be configured by the network device through RRC signaling. When configuring the PPW ID, the network device can configure one or more PPW IDs for each terminal. For example, for each terminal, the network device can configure N PPWs, each corresponding to a different PPW ID. N is a positive integer.

[0075] A PPW entry in a PPW list refers to the sequence number of each PPW in the PPW list configured by the network device for the BWP. As previously mentioned, the network device can configure a separate PPW list for each BWP included in each of multiple CCs, with each PPW list containing at least one PPW. Different PPWs in the same BWP in the same CC have different PPW entries, and different PPW entries correspond to different PPW IDs.

[0076] In one example, a network device can configure a first PPW list for BWP#1 of CC#1 through RRC signaling. This first PPW list includes four PPWs. The first PPW has a PPW ID of ID#2, corresponding to PPW entry #0; the second PPW has a PPW ID of ID#3, corresponding to PPW entry #1; the third PPW has a PPW ID of ID#4, corresponding to PPW entry #2; and the fourth PPW has a PPW ID of ID#6, corresponding to PPW entry #3. Furthermore, the network device can also configure a second PPW list for BWP#2 of CC#2. This second PPW list also includes four PPWs. The first PPW has a PPW ID of ID#1, corresponding to PPW entry #0; the second PPW has a PPW ID of ID#2, corresponding to PPW entry #1; the third PPW has a PPW ID of ID#4, corresponding to PPW entry #2; and the fourth PPW has a PPW ID of ID#5, corresponding to PPW entry #3.

[0077] It can be seen that in BWP#1 of CC#1 and BWP#2 of CC#2 (i.e., the same BWP of the same CC), the PPW entries for different PPWs are #0, #1, #2, and #3, respectively. In other words, different PPWs have different PPW entries. Furthermore, in the first PPW list, PPW entries #0, #1, #2, and #3 correspond to PPW IDs #2, #3, #4, and #6, respectively. In the second PPW list, PPW entries #0, #1, #2, and #3 correspond to PPW IDs #1, #2, #4, and #5, respectively. In other words, different PPW entries correspond to different PPW IDs.

[0078] On the other hand, if the PPW lists on the reference BWPs in different CCs include PPWs corresponding to the same PPW ID, the PPW entries for the PPWs corresponding to the same PPW ID may be the same or different. It should be noted that regardless of whether the PPW entries are the same or different, the PPWs corresponding to the same PPW ID may be considered the same PPW.

[0079] Still referring to the first PPW list configured by the network device for BWP#1 of CC#1 and the second PPW list configured for BWP#2 of CC#2, it can be seen that the first PPW list and the second PPW list include PPWs corresponding to the same PPW ID, namely, PPWs with PPW IDs ID#2 and ID#4. The PPW with PPW ID ID#2 has different PPW entries in the first PPW list and the second PPW list, while the PPW with PPW ID ID#4 has the same PPW entry in the first PPW list and the second PPW list.

[0080] In the disclosed embodiment, PPW parameters of different BWPs included in each CC of multiple CCs may be configured based on different indication information. The terminal expects that among the different BWPs included in different CCs configured with different indication information, at least one BWP corresponds to the same PPW.

[0081] In one example, the network device may configure the PPW parameters of different BWPs included in each CC based on different indication information. That is, the PPW parameters on each BWP included in each CC are independently configured, and the network device ensures during configuration that each CC includes at least one reference BWP, and that the reference BWPs of different CCs have at least one identical reference PPW.

[0082] In an embodiment of the present disclosure, the indication information may be used to indicate reference information, and the reference information includes at least one of a reference CC identifier, a reference BWP identifier, and a reference PPW identifier. The reference CC identifier is used to indicate a first CC, the reference BWP identifier is used to indicate a first BWP, and the reference PPW identifier is used to indicate a first PPW.

[0083] Furthermore, the PPW of the second BWP included in the second CC can be set to be the same as the first PPW of the first BWP on the first CC. The second CC is a CC other than the first CC among the multiple CCs. In other words, the first PPW of the first BWP in the first CC can be configured as a reference PPW. In this case, the PPW of the second BWP in the second CC can be directly configured to be the same as the first PPW, eliminating the need for network devices to repeatedly configure the PPW on the second BWP in the second CC. In some cases, other PPWs of the first BWP in the first CC can also be configured to be the same as the first PPW, further reducing repeated configuration of network devices. When the reference signal does not include a reference BWP identifier, the active BWP in the first CC can be determined as the first BWP.

[0084] Furthermore, the first CC may include at least one first CC, the first BWP may include at least one first BWP, and the PPW lists on at least one first BWP corresponding to each of the at least one first CC may all include the first PPW. That is, a first PPW may be configured and multiple CCs and / or multiple BWPs may be indicated, indicating that the first PPW is configured in the PPW lists of multiple CCs and / or multiple BWPs.

[0085] Figure 3 FIG. 1 is a flow chart showing a communication method according to an exemplary embodiment. Figure 3 As shown, the method includes the following steps.

[0086] In step S21, at least one indication information is received, where the indication information is used to indicate a PPW of a BWP included in each CC of a plurality of CCs.

[0087] Multiple CCs are used to transmit PRSs simultaneously.

[0088] In step S22, PRSs on multiple CCs are measured based on the PPW.

[0089] In the embodiment of the present disclosure, the terminal can measure PRSs on multiple CCs based on the PPW indicated by the indication information. That is, the terminal can measure multiple CCs within one instance (ie, time instance) of one PPW.

[0090] It should be noted that the CC in all embodiments of the present disclosure may also be referred to as a Positioning Frequency Layer (PFL).

[0091] A PPW appears periodically, occurring once per cycle. Its duration is equal to the number of time slots indicated by the PPW length. In related technologies, a terminal can only measure one CC or one PFL within a PPW that appears within each cycle. However, a terminal can measure different CCs or PFLs within PPWs that appear in different cycles.

[0092] In an embodiment of the present disclosure, when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation, the terminal receives at least one indication information, where the indication information is used to indicate the PPW of the BWP included in each CC in the multiple CCs, and measures the PRS on multiple CCs or multiple PFLs based on the PPW indicated by the indication information, thereby realizing the configuration of the PPW corresponding to the PRS when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation, thereby improving the accuracy of the terminal's positioning based on carrier aggregation.

[0093] Figure 4 FIG. 1 is a flow chart showing a communication method according to an exemplary embodiment. Figure 4 As shown, the communication method is executed by a network device and includes the following steps.

[0094] In step S31 , a PPW of a BWP included in each CC among multiple CCs is configured.

[0095] Multiple CCs are used to transmit PRSs simultaneously.

[0096] In step S32, at least one indication message is sent, where the indication message is used to indicate the PPW.

[0097] In an embodiment of the present disclosure, a network device may configure a PPW for a BWP included in each of multiple CCs, and transmit the PPW to a terminal via at least one indication message, so that the terminal can measure PRSs transmitted simultaneously on multiple CCs based on the PPW. Furthermore, the multiple CCs are used to simultaneously transmit PRSs. That is, a bandwidth aggregation method can be used to simultaneously transmit PRSs based on the BWPs in the multiple CCs, and the PPW is used to configure the time for the terminal to measure the PRSs. The PPW can be pre-configured by the network device and activated or deactivated by the network device via a downlink message. Furthermore, the PPW may also include a PRS processing time, that is, the terminal can also perform measurement processing on the PRSs in the PPW.

[0098] Using the bandwidth aggregation method to send PRS can be to activate a BWP on each of multiple CCs and simultaneously send PRS based on the activated BWPs in a carrier aggregation manner. The network device can pre-configure a PPW list for each BWP through Radio Resource Control (RRC) signaling, and each PPW list includes at least one PPW. When sending PRS based on the activated BWPs in a carrier aggregation manner, the network device can further activate a PPW in the PPW list of each BWP so that the terminal can measure PRS in the PPW.

[0099] In the disclosed embodiments, the indication information may be carried in the RRC. The PPW on at least one BWP included in each of the multiple CCs is configured via RRC signaling, and the PPW of the BWP included in each CC in the multiple CCs is indicated to the terminal, thereby enabling the configuration of the PPW corresponding to the PRS when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation.

[0100] By adopting the technical solution of the embodiment of the present disclosure, by configuring the PPW of the BWP included in each CC in multiple CCs and sending at least one indication information to indicate the PPW, the configuration of each PPW is realized when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation, thereby improving the accuracy of terminal positioning based on carrier aggregation.

[0101] In an embodiment of the present disclosure, each of the multiple CCs may include a reference BWP, where the reference BWP is the BWP used to perform carrier aggregation on the multiple CCs to simultaneously transmit PRS. The reference BWPs of different CCs have at least one identical reference PPW, where the reference PPW is a PPW that includes reference PPW parameters.

[0102] At this time, the PPW of the BWP included in each CC in the multiple CCs can be configured by Figure 5 The method shown is implemented. Figure 5 As shown, the method includes the following steps.

[0103] In step S41 , reference BWPs of different CCs are configured to have at least one identical reference PPW.

[0104] The reference PPW is a PPW including reference PPW parameters.

[0105] In this embodiment of the present disclosure, each of multiple CCs may include at least one BWP, and at least one of the at least one BWPs included in each of the multiple CCs is a reference BWP. When PRSs are simultaneously transmitted using the bandwidth aggregation method for multiple CCs, the BWP activated for aggregation in each CC is the reference BWP. Furthermore, other BWPs in each CC may or may not be reference BWPs. Reference BWPs in different CCs share at least one reference PPW, which is a PPW that includes reference PPW parameters.

[0106] In the embodiment of the present disclosure, the network device may configure the BWP included in each CC in multiple CCs to include at least one reference BWP.

[0107] In one example, if multiple CCs are CC#1, CC#2, and CC#3, CC#1 includes BWP#1 and BWP#4, CC#2 includes BWP#2 and BWP#5, and CC#3 includes BWP#3 and BWP#6, BWP#1 of CC#1, BWP#2 of CC#2, and BWP#3 of CC#3 can all be set as reference BWPs. That is, BWP#1, BWP#2, and BWP#3 are set to have at least one identical reference PPW. In other words, the PPW list configured by the network device for BWP#1, the PPW list configured for BWP#2, and the PPW list configured for BWP#3 each include at least one identical reference PPW, and the reference PPWs include identical reference PPW parameters.

[0108] Furthermore, the remaining PPWs in the PPW list configured for BWP#1, the PPW list configured for BWP#2, and the PPW list configured for BWP#3 may or may not be reference PPWs. Furthermore, the PPWs in BWP#4 of CC#1, BWP#5 of CC#2, and BWP#6 of CC#3 may or may not be reference PPWs. If the PPWs in BWP#4, BWP#5, and BWP#6 are not reference PPWs, when PRS is transmitted via carrier aggregation based on CC#1, CC#2, and CC#3, only BWP#1 of CC#1, BWP#2 of CC#2, and BWP#3 of CC#3 can be activated for aggregation to ensure that the PPWs of CC#1, CC#2, and CC#3 are consistent. This ensures that the terminal can measure PRS transmitted at the same symbol position, or time domain position, on different CCs within the same PPW time.

[0109] Those skilled in the art will appreciate that the above description is merely illustrative. In practice, BWP#4 of CC#1, BWP#5 of CC#2, and BWP#6 of CC#3 may each include at least one identical reference PPW, while BWP#1 of CC#1, BWP#2 of CC#2, and each PPW in CC#3 may or may not be a reference PPW. This is analogous and will not be further described here.

[0110] In the embodiment of the present disclosure, the network device may further configure all BWPs included in each CC among multiple CCs to be reference BWPs, that is, all BWPs included in each CC include at least one identical reference PPW.

[0111] In one example, if multiple CCs are CC#1, CC#2, and CC#3, each of which includes one or more BWPs, all BWPs included in CC#1, CC#2, and CC#3 can be set as reference BWPs, that is, all BWPs included in CC#1, CC#2, and CC#3 can be set to include at least one identical reference PPW. In this case, when PRS is transmitted via carrier aggregation based on CC#1, CC#2, and CC#3, any BWP in CC#1, any BWP in CC#2, and any BWP in CC#3 can be activated for aggregation, ensuring that the PPWs of CC#1, CC#2, and CC#3 are consistent. This ensures that the terminal can measure PRSs transmitted at the same symbol position, or time domain position, on different CCs within the same PPW time. Furthermore, those skilled in the art will appreciate that other PPWs in each BWP may or may not be reference PPWs.

[0112] In the embodiment of the present disclosure, the PPW parameter may include at least one of the following:

[0113] PPW identification ID;

[0114] PPW entry in the PPW list;

[0115] The temporal location of the PPW;

[0116] PPW length;

[0117] PPW type;

[0118] PPW priority.

[0119] Each PPW parameter can be configured by the network device through RRC signaling. When configuring the PPW ID, the network device can configure one or more PPW IDs for each terminal. For example, for each terminal, the network device can configure N PPWs, each corresponding to a different PPW ID. N is a positive integer.

[0120] A PPW entry in a PPW list refers to the sequence number of each PPW in the PPW list configured by the network device for the BWP. As previously mentioned, the network device can configure a separate PPW list for each BWP included in each of multiple CCs, with each PPW list containing at least one PPW. Different PPWs in the same BWP in the same CC have different PPW entries, and different PPW entries correspond to different PPW IDs.

[0121] In one example, a network device can configure a first PPW list for BWP#1 of CC#1 through RRC signaling. This first PPW list includes four PPWs. The first PPW has a PPW ID of ID#2, corresponding to PPW entry #0; the second PPW has a PPW ID of ID#3, corresponding to PPW entry #1; the third PPW has a PPW ID of ID#4, corresponding to PPW entry #2; and the fourth PPW has a PPW ID of ID#6, corresponding to PPW entry #3. Furthermore, the network device can also configure a second PPW list for BWP#2 of CC#2. This second PPW list also includes four PPWs. The first PPW has a PPW ID of ID#1, corresponding to PPW entry #0; the second PPW has a PPW ID of ID#2, corresponding to PPW entry #1; the third PPW has a PPW ID of ID#4, corresponding to PPW entry #2; and the fourth PPW has a PPW ID of ID#5, corresponding to PPW entry #3.

[0122] It can be seen that in BWP#1 of CC#1 and BWP#2 of CC#2 (i.e., the same BWP of the same CC), the PPW entries for different PPWs are #0, #1, #2, and #3, respectively. In other words, different PPWs have different PPW entries. Furthermore, in the first PPW list, PPW entries #0, #1, #2, and #3 correspond to PPW IDs #2, #3, #4, and #6, respectively. In the second PPW list, PPW entries #0, #1, #2, and #3 correspond to PPW IDs #1, #2, #4, and #5, respectively. In other words, different PPW entries correspond to different PPW IDs.

[0123] On the other hand, if the PPW lists on the reference BWPs in different CCs include PPWs corresponding to the same PPW ID, the PPW entries for the PPWs corresponding to the same PPW ID may be the same or different. It should be noted that regardless of whether the PPW entries are the same or different, the PPWs corresponding to the same PPW ID may be considered the same PPW.

[0124] Still referring to the first PPW list configured by the network device for BWP#1 of CC#1 and the second PPW list configured for BWP#2 of CC#2, it can be seen that the first PPW list and the second PPW list include PPWs corresponding to the same PPW ID, namely, PPWs with PPW IDs ID#2 and ID#4. The PPW with PPW ID ID#2 has different PPW entries in the first PPW list and the second PPW list, while the PPW with PPW ID ID#4 has the same PPW entry in the first PPW list and the second PPW list.

[0125] In the disclosed embodiment, PPW parameters of different BWPs included in each CC of multiple CCs may be configured based on different indication information. The terminal expects that among the different BWPs included in different CCs configured with different indication information, at least one BWP corresponds to the same PPW.

[0126] In one example, the network device may configure the PPW parameters of different BWPs included in each CC based on different indication information. That is, the PPW parameters on each BWP included in each CC are independently configured, and the network device ensures during configuration that each CC includes at least one reference BWP, and that the reference BWPs of different CCs have at least one identical reference PPW.

[0127] In an embodiment of the present disclosure, the indication information may be used to indicate reference information, and the reference information includes at least one of a reference CC identifier, a reference BWP identifier, and a reference PPW identifier. The reference CC identifier is used to indicate a first CC, the reference BWP identifier is used to indicate a first BWP, and the reference PPW identifier is used to indicate a first PPW.

[0128] Furthermore, the PPW of the second BWP included in the second CC can be set to be the same as the first PPW of the first BWP on the first CC. The second CC is a CC other than the first CC among the multiple CCs. In other words, the first PPW of the first BWP in the first CC can be configured as a reference PPW. In this case, the PPW of the second BWP in the second CC can be directly configured to be the same as the first PPW, eliminating the need for network devices to repeatedly configure the PPW on the second BWP in the second CC. In some cases, other PPWs of the first BWP in the first CC can also be configured to be the same as the first PPW, further reducing repeated configuration of network devices. When the reference signal does not include a reference BWP identifier, the active BWP in the first CC can be determined as the first BWP.

[0129] Furthermore, the first CC may include at least one first CC, the first BWP may include at least one first BWP, and the PPW lists on at least one first BWP corresponding to each of the at least one first CC may all include the first PPW. That is, a first PPW may be configured and multiple CCs and / or multiple BWPs may be indicated, indicating that the first PPW is configured in the PPW lists of multiple CCs and / or multiple BWPs.

[0130] Figure 6 FIG. 1 is a flow chart showing a communication method according to an exemplary embodiment. Figure 6 As shown, the method includes the following steps.

[0131] In step S51, a PPW of a BWP included in each of a plurality of CCs is configured, and the plurality of CCs are used to transmit PRSs simultaneously.

[0132] In step S52, at least one indication message is sent, where the indication message is used to indicate the PPW.

[0133] In step S53 , a PRS measurement result is received.

[0134] The PRS measurement result is obtained by the terminal measuring the PRSs on the multiple CCs based on the PPW.

[0135] In an embodiment of the present disclosure, a network device may receive a PRS measurement result reported by a terminal, where the PRS measurement result is obtained by the terminal measuring the PRSs on the multiple CCs based on the PPW. The terminal may measure multiple CCs within a PFL of a PPW.

[0136] A PPW appears periodically, occurring once per cycle. Its duration is equal to the number of time slots indicated by the PPW length. In related technologies, a terminal can only measure one CC or one PFL within a PPW that appears within each cycle. However, a terminal can measure different CCs or PFLs within PPWs that appear in different cycles.

[0137] In an embodiment of the present disclosure, when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation, the network device sends at least one indication information, where the indication information is used to indicate the PPW of the BWP included in each CC in the multiple CCs, and measures the PRS on multiple CCs or multiple PFLs based on the PPW indicated by the indication information, thereby realizing the configuration of the PPW corresponding to the PRS when PRS is transmitted simultaneously based on multiple CCs under bandwidth aggregation, thereby improving the accuracy of the terminal's positioning based on carrier aggregation.

[0138] In the embodiments of the present disclosure, the network device may be a radio access network device or a core network device. The operations of configuring the PPW of the BWP included in each of the multiple CCs and sending at least one indication message may be implemented by the radio access network device, and the operation of receiving the PRS measurement result reported by the terminal may be implemented by an LMF network element in the core network.
