[0045] In addition, the following points are explained in order to facilitate understanding of the embodiments of the present disclosure.

[0046] First, in the embodiments of the present disclosure, “for indicating” can include for directly indicating and for indirectly indicating. When describing that a certain information is for indicating A, it can include that the information carries A, or it can also include that the information directly indicates A or indirectly indicates A, and it does not mean that the information must carry A.

[0047] The information indicated by the information is called to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by a protocol), thereby reducing the indication overhead to a certain extent.

[0048] The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited by the present disclosure. The sending period and / or sending occasion of the sub-information can be predefined, for example, predefined according to a protocol.

[0049] Second, in the present disclosure, the first, second, and various numerical numbers (for example, “#1”, “#2”) are only for differentiation for convenience of description, and do not limit the scope of the embodiments of the present disclosure. For example, different information is distinguished.

[0050] Third, the embodiments of the present disclosure enumerate a plurality of embodiments to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the plurality of embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together in combination with the method of other embodiments of the present disclosure, or can be executed alone or together in combination with some methods in other related technologies; the present disclosure does not limit this.

[0051] In Release 18 (Rel-18), in order to improve the accuracy of time-based positioning methods, a method of bandwidth aggregation is considered to transmit PRS / SRS.

[0052] In Rel-17, in order to reduce the positioning latency, a PRS processing window (PPW) is introduced to perform PRS measurement within the window outside the gap without measurement gap. In Rel-17, the PPW is configured per cell. The activation of the PPW is also activated per cell per window.

[0053] In some embodiments, each PPW configuration parameter includes at least one of:

[0054] PPW ID;

[0055] Periodicity and starting slot position of the PPW;

[0056] Length (i.e. the time length occupied, the number of slots);

[0057] Type (Type refers to whether the terminal device affects one CC or multiple CCs within this PPW, or whether the PRS is in the symbol or the PPW is in the symbol).

[0058] In some embodiments, the type includes at least one of:

[0059] Type 1: If the PRS priority is high, the priority of the PRS is higher than the downlink channel / signal on all symbols in the PPW. (The PRS has priority over all other downlink signals / channels in all symbols inside the window.)

[0060] Type 1A: The PRS priority is higher than the downlink channel / signal on all CCs of the terminal device. (The DL signals / channels from all DL CCs (per UE) are affected. The DL signals / channels from all DL CCs (per UE) are affected.)

[0061] Type 1B: PRS has higher priority than downlink channel / signal on the terminal device specified band (band where the PRS is specified). (Only the DL signals / channels from a certain band are affected.)

[0062] Type 2: If PRS has higher priority, only higher than downlink channel / signal on the PRS symbol. (PRS prioritization over other DL signals / channels only in the PRS symbols inside the window.)

[0063] In some embodiments, the priority indicates the priority between PRS and physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH) / channel state information reference signal (CSI-RS).

[0064] State 1: PRS has higher priority than all downlink channel / signal, except Synchronization Signal Block (SSB). (State 1: PRS is higher priority than all DL channel / signal except SSB.) That is, including PDCCH / PDSCH / DMRS / CSI-RS.

[0065] State 2: PRS is lower priority than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other DL signals / channels except SSB.

[0066] State 3: PRS is lower priority than all the DL signals / channels except SSB.

[0067] It should be noted that if the PRS priority is high, the PRS is received, otherwise the PRS is not received.

[0068] Exemplarily, a downlink PPW pre-configuration information element (DL-PPW-PreConfig information element):

[0069]

[0070]

[0071] In the related art, PPW activation is based on a medium access control control element (MAC CE), which indicates a component carrier (CC) ID and a PPW ID to indicate the activation of the PPW corresponding to the PPW ID on the active bandwidth part (BWP) of the CC ID.

[0072] Wherein, one MAC CE can only activate the PPW ID corresponding to the active BWP on one CC.

[0073] Based on this, the embodiment of the present disclosure provides a positioning reference signal PRS processing window (PPW) activation method, a terminal device receives indication information sent by a network side device, wherein the indication information is used to indicate the activation of the PPW on multiple CCs. Thereby, the indication information can activate the PPW on multiple CCs at the same time, and the signaling overhead can be saved.

[0074] It should be noted that in the positioning reference signal PRS processing window (PPW) activation method and device provided by the present disclosure, the CC can be replaced by a positioning frequency layer (PFL), and the present disclosure is described by taking the CC as an example.

The indication information can include multiple ones of a PPW identifier, an entry corresponding to the PPW in a PPW list, a cell identifier, multi-CC indication information, and a BWP identifier. The above embodiments are only illustrative and not used as a specific limitation on the protection scope of the embodiments of the present disclosure.

[0131] For example, the indication information includes a PPW identifier and a cell identifier. In this case, the indication information can be used to indicate the activation of a PPW corresponding to the PPW identifier on at least one CC corresponding to the cell identifier in the multiple CCs.

[0132] For example, the indication information includes a PPW identifier, a cell identifier, and a BWP identifier. In this case, the indication information can be used to indicate the activation of a PPW corresponding to the PPW identifier on a BWP corresponding to the BWP identifier on at least one CC corresponding to the cell identifier in the multiple CCs.

[0133] In some embodiments, the multi-CC indication information comprises at least one of:

[0134] CC list information comprising a plurality of CCs;

[0135] Information for indicating whether the indication information is applicable to a plurality of CCs.

[0136] In the embodiments of the present disclosure, the multi-CC indication information can comprise: CC list information comprising a plurality of CCs.

[0137] The CC list information can comprise an ID of a CC list. The information of the CC corresponding to the CC list ID can be obtained through RRC configuration information of a network device or based on a default rule specified by a protocol. The CC list can comprise CC identifiers corresponding to a plurality of CCs.

[0138] For example, the numbering of the CC identifier can be numbered from all serving cells corresponding to the terminal device configuration, not only from a plurality of CCs corresponding to the PRS, such as CC#3 and CC#4, but also from CC#1, CC#2 and CC#5 corresponding to other communications of the terminal device (of course, the other communications can also use CC#3 and CC#4, and here, it is only illustrated that the other communications can also comprise CCs other than the CCs occupied by the PRS); in this case, the numbering of the CC identifier is numbered from 5 CCs, and if numbered from 0, 3 bits of each CC identifier in the RRC signaling are required, so that the numbering of each CC can be determined according to 3 bits of identifiers corresponding to the 5 CCs.

[0139] For example, the numbering of the CC identifier can be numbered from the CCs corresponding to the PRS of the terminal device, and the CCs not occupied by the PRS are not included. For example, the CCs corresponding to the PRS are CC#3 and CC#4, and the CCs corresponding to other communications of the terminal device are CC#1, CC#2 and CC#5 (of course, the other communications can also use CC#3 and CC#4), in this case, the numbering of the CC identifier is numbered from 2 CCs corresponding to the PRS, and if numbered from 0, 1 bit of each CC identifier in the RRC signaling is required, so that the numbering of each CC can be determined according to 1 bit of identifiers corresponding to the 2 CCs.

[0140] In the embodiments of the present disclosure, the multi-CC indication information can comprise: information for indicating whether the indication information is applicable to a plurality of CCs.

[0141] The information for indicating whether the indication information is applicable to a plurality of CCs can be 1 bit of information.

[0142] Exemplarily, in a case that the 1-bit information is 1, it can be indicated that the indication information is applicable to multiple CCs, for example, is applicable to multiple CCs included in the CC list information, and in a case that the 1-bit information is 0, it can be indicated that the indication information is not applicable to multiple CCs, for example, is not applicable to multiple CCs included in the CC list information. Here, the CC list can be default to contain all CCs used for PRS transmission.

[0143] It should be noted that the above embodiments are not exhaustive, and only some embodiments are shown, and the above embodiments can be implemented alone or in combination with multiple embodiments. The above embodiments are only used as an example and do not specifically limit the protection scope of the embodiments of the present disclosure.

[0144] In some embodiments, if the indication information includes the BWP identifier, the indication information is used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the multiple CCs; or, if the indication information does not include the BWP identifier, the indication information is used to indicate the PPW on the activated BWP on at least one of the multiple CCs.

[0145] In the embodiments of the present disclosure, in a case that the indication information includes the BWP identifier, the indication information can be used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the multiple CCs.

[0146] In the embodiments of the present disclosure, in a case that the indication information does not include the BWP identifier, the indication information can be used to indicate the PPW on the activated BWP on at least one of the multiple CCs.

[0147] In some embodiments, in a case that the indication information includes an entry in a PPW list corresponding to the PPW, the indication information is used to indicate the PPW corresponding to the entry in the PPW list on each of the multiple CCs.

[0148] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the multiple CCs, and in a case that the indication information includes an entry in a PPW list corresponding to the PPW, the indication information can be used to indicate the PPW corresponding to the entry in the PPW list on each of the multiple CCs.

[0149] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the multiple CCs, and in a case that the indication information includes an entry in a PPW list corresponding to the PPW, the indication information can be used to indicate the PPW corresponding to the entry in the PPW list on the activated BWP on each of the multiple CCs.

[0150] Optionally, the indication information is used to indicate to activate the PPWs on multiple CCs, in the case that the indication information includes entries in a PPW list corresponding to the PPWs, the PPWs activated on multiple CCs can all be the PPWs configured by the entries (entries in the PPW list) contained in the MAC CE. Because the PPW list on each BWP of each cell is configured independently, i.e., the MAC CE can activate the PPW configuration of the PPW entry such as entry #0 on multiple CCs, i.e., ignore the cell ID of the MAC CE, and is applicable to multiple cell IDs. However, the premise of this method is that the specified parameters of the PPW with entry #0 in the PPW list on the BWP of each of the multiple CCs configured by RRC are the same, of course, it can also include different cases.

[0151] That is, the MAC CE indicates the entries corresponding to multiple PPWs in the PPW list configured by RRC in the BWP. For example, the RRC configuration is as follows:

[0152] The PPW list of the activated BWP #1 of CC #1 contains four PPWs,

[0153] The first PPW ID is ID #2, and the corresponding entry is #0;

[0154] The second PPW ID is ID #4, and the corresponding entry is #1;

[0155] The third PPW ID is ID #5, and the corresponding entry is #2;

[0156] The fourth PPW ID is ID #6, and the corresponding entry is #3;

[0157] The PPW list of the activated BWP #2 of CC #2 contains four PPWs,

[0158] The first PPW ID is ID #1, and the corresponding entry is #0;

[0159] The second PPW ID is ID #2, and the corresponding entry is #1;

[0160] The third PPW ID is ID #5, and the corresponding entry is #2;

[0161] The fourth PPW ID is ID #4, and the corresponding entry is #3;

[0162] In the above example, the same PPW ID indicates the same PPW.

[0163] In an embodiment, if the entry in the PPW list contained in the MAC CE is #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #2 on the active BWP #1 of CC#1, and activates the PPW with PPW ID #1 on the active BWP #2 of CC#2. It can be understood that the PPWs activated by the MAC CE on the two CCs are different.

[0164] In another embodiment, if the entry in the PPW list contained in the MAC CE is #2, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #5 on the active BWP #1 of CC#1, and activates the PPW with PPW ID #5 on the active BWP #2 of CC#2. It can be understood that the PPWs activated by the MAC CE on the two CCs are the same.

[0165] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on multiple CCs, and in the case that the indication information includes the entry in the PPW list corresponding to the PPW and the BWP identifier, the indication information can be used to indicate the activation of the PPW corresponding to the entry in the PPW list on the BWP corresponding to the BWP identifier on each of the multiple CCs.

[0166] In some embodiments, in the case that the indication information includes the entry in the PPW list corresponding to the PPW, the indication information is used to indicate the activation of the PPW corresponding to the first PPW identifier on each of the multiple CCs, and the first PPW identifier is the PPW identifier corresponding to the entry in the PPW list on the specified CC. When the indication information contains the cell identifier, the specified CC is the CC corresponding to the cell identifier; when the indication information does not contain the cell identifier, the specified CC is the CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0167] In the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on multiple CCs, and in the case that the indication information includes the entry in the PPW list corresponding to the PPW, the indication information can be used to indicate the activation of the PPW corresponding to the first PPW identifier on each of the multiple CCs, and the first PPW identifier is the PPW identifier corresponding to the entry in the PPW list on the specified CC. When the indication information contains the cell identifier, the specified CC is the CC corresponding to the cell identifier; when the indication information does not contain the cell identifier, the specified CC is the CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0168] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs, the indication information can be used to indicate the activation of the PPW corresponding to a first PPW identifier on a BWP activated on each of the multiple CCs, the first PPW identifier being a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0169] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs and a BWP identifier, the indication information can be used to indicate the activation of the PPW corresponding to a first PPW identifier on a BWP corresponding to the BWP identifier on each of the multiple CCs, the first PPW identifier being a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0170] Optionally, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs, the PPWs activated on the multiple CCs can all be the PPW corresponding to a first PPW identifier. The first PPW identifier is a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS. Because the PPW list on each BWP of each cell is independently configured, i.e., the MAC CE can activate the PPW ID #0 on the multiple CCs, i.e., ignore the cell identifier of the MAC CE, and be applicable to multiple cell IDs. However, the premise of this method is that the PPW ID #0 corresponding PPW is contained in the RRC configured PPW list on the BWP of each of the multiple CCs.

[0171] That is, the MAC CE indicates the entries corresponding to multiple PPWs in the RRC configured PPW list in the BWP. For example, the RRC configuration is as follows:

[0172] The PPW list of the activated BWP #1 of the CC #1 contains four PPWs,

[0173] The first PPW ID is ID#2, and the corresponding entry is #0;

[0174] The second PPW ID is ID#4, and the corresponding entry is #1;

[0175] The third PPW ID is ID#5, and the corresponding entry is #2;

[0176] The fourth PPW ID is ID#6, and the corresponding entry is #3;

[0177] The PPW list of the activated BWP#2 of CC#2 contains four PPWs,

[0178] The first PPW ID is ID#1, and the corresponding entry is #0;

[0179] The second PPW ID is ID#2, and the corresponding entry is #1;

[0180] The third PPW ID is ID#5, and the corresponding entry is #2;

[0181] The fourth PPW ID is ID#4, and the corresponding entry is #3;

[0182] In the above example, the same PPW ID indicates the same PPW.

[0183] In an embodiment, if the entry in the PPW list contained in the MAC CE is #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier, and the cell identifier is CC#1. Therefore, it is equivalent to that the MAC CE activates the PPW with the PPW ID of #2 (i.e., the first PPW identifier is PPW ID#2) on the activated BWP#1 of CC#1, and also activates the PPW with the PPW ID of #2 on the activated BWP#2 of CC#2. That is, regardless of whether the entry in the PPW list corresponding to the PPW with the PPW ID of #2 on the activated BWP of CC#2 is #0, the MAC CE activates the PPW with the PPW ID of #2 on the BWP of each CC. It can be understood that the PPW activated by the MAC CE on the two CCs is the same. In this case, it is also required that the PPW corresponding to the first PPW identifier is contained in the PPW list on the BWP of CC#2.

[0184] In an embodiment, if the entry in the PPW list contained in the MAC CE is #1, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier, and the cell identifier is CC#1. Therefore, it is equivalent to the MAC CE activating the PPW with PPW ID #4 (i.e., the first PPW identifier is PPW ID #4) on the active BWP #1 of CC#1, and also activating the PPW with PPW ID #4 on the active BWP #2 of CC#2. That is, regardless of whether the entry in the PPW list corresponding to the PPW with PPW ID #4 on the active BWP of CC#2 is #1, the MAC CE activates the PPW with PPW ID #4 on the BWP of each CC. It can be understood that the PPW activated by the MAC CE on the two CCs is the same. In this case, it is also required that the PPW corresponding to the first PPW identifier is contained in the PPW list on the BWP of CC#2.

[0185] In some embodiments, in the case where the indication information includes the PPW identifier, the indication information is used to indicate the PPW corresponding to the PPW identifier on each of the plurality of CCs.

[0186] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on each of the plurality of CCs.

[0187] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the active BWP of each of the plurality of CCs.

[0188] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier and the BWP identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the BWP corresponding to the BWP identifier on each of the plurality of CCs.

[0189] Optionally, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the PPW on the plurality of CCs can all be the PPW corresponding to the PPW identifier. Because the PPW list on each BWP of each cell is independently configured, i.e., the MAC CE can activate the PPW with PPW ID #0 on the plurality of CCs, i.e., the cell identifier of the MAC CE is ignored, and is applicable to multiple cell IDs. However, the prerequisite of this method is that the PPW corresponding to PPW ID #0 is contained in the PPW list on the BWP of each of the plurality of CCs configured by RRC.

[0190] That is, the MAC CE indicates the entries corresponding to multiple PPWs in the RRC configured PPW list in the BWP. For example, the RRC configuration is as follows:

[0191] The PPW list of the activated BWP#1 of CC#1 contains four PPWs,

[0192] The first PPW ID is ID#2, and the corresponding entry is #0;

[0193] The second PPW ID is ID#4, and the corresponding entry is #1;

[0194] The third PPW ID is ID#5, and the corresponding entry is #2;

[0195] The fourth PPW ID is ID#6, and the corresponding entry is #3;

[0196] The PPW list of the activated BWP#2 of CC#2 contains four PPWs,

[0197] The first PPW ID is ID#1, and the corresponding entry is #0;

[0198] The second PPW ID is ID#2, and the corresponding entry is #1;

[0199] The third PPW ID is ID#5, and the corresponding entry is #2;

[0200] The fourth PPW ID is ID#4, and the corresponding entry is #3;

[0201] In the above example, the same PPW ID indicates the same PPW.

[0202] In an embodiment, if the MAC CE contains PPW ID #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain BWP ID. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #0 on the activated BWP#1 of CC#1, and activates the PPW with PPW ID #0 on the activated BWP#2 of CC#2. That is, the MAC CE directly indicates the PPW ID corresponding to the RRC configured PPW, rather than the entry in the RRC configured PPW list. It can be understood that the PPWs on the two CCs activated by the MAC CE are the same. In this case, it is also required that the PPW list on at least one BWP of each of the multiple CCs contains at least the PPW corresponding to the same PPW ID.

[0203] In the embodiments or examples, each step can be independent, arbitrarily combined or exchanged in sequence, optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with other embodiments or examples without contradiction.

[0204] By implementing the embodiments of the present disclosure, the terminal device receives the indication information sent by the network side device, wherein the indication information is used to indicate the activation of the PPW on multiple CCs. Thus, the indication information can activate the PPW on multiple CCs at the same time, and the signaling overhead can be saved.

[0205] Please refer to Figure 3 , Figure 3 is a flowchart of another method for activating a positioning reference signal (PRS) processing window (PPW) provided by the embodiments of the present disclosure. As Figure 3 shown, the method is performed by a terminal device, and the method can include but is not limited to the following steps:

[0206] S31: receiving indication information sent by a network side device, wherein the indication information is used to indicate the activation of the PPW on multiple CCs.

[0207] The related description of S31 can be referred to the related description in the above embodiments, which will not be repeated here.

[0208] S32: measuring the PRS on multiple CCs or PFLs within a single time instance within the PPW.

[0209] In the embodiments of the present disclosure, after the terminal device receives the indication information sent by the network side device and activates the PPW on multiple CCs, the terminal device can measure the PRS on multiple CCs within a single time instance within the PPW, or can also measure the PRS on multiple positioning frequency layers (PFLs) within a single time instance within the PPW.

[0210] It can be understood that the PPW can occur periodically, only once in a period, and the length of time occupied is the number of slots indicated by the length of the PPW, that is, in the PPW occurring once in each period, only one CC or one PFL can be measured in the related art, and different CCs or different PFLs can be measured in the PPW occurring in different periods. However, in the case of carrier aggregation, it is necessary to support the measurement of the PRS on multiple CCs or multiple PFLs within the PPW occurring once in each period.

[0211] Based on this, in the embodiments of the present disclosure, the terminal device receives the indication information sent by the network side device and activates the PPW on multiple CCs, and can measure the PRS on multiple CCs or PFLs within a single time instance within the PPW.

[0212] It should be noted that the related description of the indication information can refer to the related description in the above embodiments, which will not be repeated here.

[0213] It should be noted that in the embodiments of the present disclosure, S31 and S32 can be implemented independently, or can be implemented in combination with any other step in the embodiments of the present disclosure, such as in combination with S21 in the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitations.

[0214] In the present embodiment or example, each step can be independently combined or exchanged in order without contradiction, and optional modes or examples can be combined with other embodiments or examples.

[0215] By implementing the embodiments of the present disclosure, the terminal device receives the indication information sent by the network side device, wherein the indication information is used to indicate to activate the PPW on multiple CCs, and to measure the PRS on multiple CCs or PFLs within a single time instance in the PPW. Thus, the indication information can activate the PPW on multiple CCs at the same time, can save signaling overhead, and can support the measurement of PRS on multiple CCs or PFLs within a single time instance in the PPW under the condition of carrier aggregation.

[0216] Please refer to Figure 4 , Figure 4 is a flowchart of a positioning reference signal PRS processing window (PPW) configuration method provided by the embodiments of the present disclosure. As Figure 4 shown, the method is executed by a terminal device, and the method can include but is not limited to the following steps:

[0217] S41: receiving RRC signaling sent by a network side device, wherein the RRC signaling is used to configure the PPW on multiple CCs, and the multiple CCs are used to simultaneously transmit PRS.

[0218] In the embodiments of the present disclosure, the terminal device can receive the RRC signaling sent by the network side device, and the RRC signaling is used to configure the PPW on multiple CCs, so that the terminal device can determine the PPW on multiple CCs.

[0219] Wherein, the multiple CCs are used to simultaneously transmit PRS.

[0220] In some embodiments, the RRC signaling is used to configure a PPW list on at least one BWP included by each of the multiple CCs, and each PPW list includes at least one PPW.

[0221] In the embodiments of the present disclosure, the RRC signaling is used to configure a PPW list on at least one BWP respectively included in the plurality of CCs, and each PPW list includes at least one PPW. In this way, the terminal device can determine the PPW on the plurality of CCs.

[0222] In some embodiments, the RRC signaling is used to configure a second specified parameter of the PPW, and the at least one PPW on the at least one BWP respectively included in the plurality of CCs corresponds to the same second specified parameter; wherein the second specified parameter includes at least one of the following:

[0223] a PPW identifier;

[0224] an entry of the PPW in a PPW list;

[0225] time domain location information of the PPW;

[0226] a length of the PPW;

[0227] a type of PRS corresponding to the PPW;

[0228] a priority of PRS corresponding to the PPW.

[0229] In the embodiments of the present disclosure, the RRC signaling can also configure a second specified parameter of the PPW. Wherein the at least one PPW on the at least one BWP respectively included in the plurality of CCs corresponds to the same second specified parameter.

[0230] In the embodiments of the present disclosure, the second specified parameter can include a PPW identifier. It can be understood that the PPW identifier (ID) can be a PPW identifier configured by the network side device through the RRC signaling.

[0231] In the embodiments of the present disclosure, the second specified parameter can include an entry of the PPW in a PPW list.

[0232] In the embodiments of the present disclosure, the second specified parameter can include time domain location information of the PPW.

[0233] Wherein, the time domain location information of the PPW can include at least one of a period of the PPW, a starting slot position, and a starting slot.

[0234] In the embodiments of the present disclosure, the second specified parameter can include a length of the PPW.

[0235] Wherein, the length of the PPW can be a number of time slots occupied by the PPW, or a number of time slots occupied by each PPW in the case of a plurality of PPWs with periodicity, etc.

[0236] In the embodiments of the present disclosure, the second specified parameter can include a type of PRS corresponding to the PPW.

[0237] The type corresponding to the PRS can be a type when the PRS priority is high.

[0238] Exemplarily, the type can refer to whether the terminal device affects one CC or multiple CCs within the PPW, or whether the PRS is in a symbol or the PPW is in a symbol.

[0239] In some embodiments, the type corresponding to the PRS includes at least one of the following:

[0240] Type 1: If the PRS priority is high, the priority of the PRS is higher than the downlink channel / signal on all symbols within the PPW. (The PRS is prioritized over all other downlink signals / channels in all symbols within the window.)

[0241] Type 1A: The PRS priority is higher than the downlink channel / signal on all CCs of the terminal device. (The DL signals / channels from all downlink CCs (per terminal device) are affected.)

[0242] Type 1B: The PRS priority is higher than the downlink channel / signal on a specified band of the terminal device, such as the PRS being in the band. (Only the DL signals / channels from a certain band are affected.)

[0243] Type 2: If the PRS priority is high, only the downlink channel / signal on the symbol where the PRS is located is high. (The PRS is prioritized over other downlink signals / channels only in the PRS symbols inside the window.)

[0244] In the embodiments of the present disclosure, the second specified parameter can include the priority corresponding to the PRS.

[0245] The priority corresponding to the PRS indicates the priority between the PRS and a PDCCH / PDSCH / CSI-RS.

[0246] Exemplarily, the priority corresponding to the PRS includes at least one of the following states:

[0247] State 1: The priority of the PRS is higher than all downlink channels / signals except Synchronization Signal Block (SSB). (State 1: The priority of the PRS is higher than all downlink channels / signals except Synchronization Signal Block (SSB).) That is, including PDCCH / PDSCH / DMRS / CSI-RS.

[0248] State 2: The priority of the PRS is lower than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other downlink signals / channels except SSB. (State 2: The priority of the PRS is lower than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other downlink signals / channels except SSB.)

[0249] State 3: The priority of the PRS is lower than all downlink signals / channels except SSB. (State 3: The priority of the PRS is lower than all downlink signals / channels except SSB.)

[0250] It should be noted that if the priority of the PRS is high, the terminal device receives the PRS, otherwise it does not receive the PRS.

[0251] It should be noted that the above embodiments are not exhaustive, only some embodiments are shown, and the above embodiments can be implemented alone or in combination with multiple embodiments. The above embodiments are only illustrative and not specific limitations on the protection scope of the embodiments of the present disclosure.

[0252] Exemplarily, the second specified parameters of the PPW configuration on the BWP#1 of the CC#1, the BWP#2 of the CC#2 and the BWP#3 of the CC#3 are the same, and there can be other PPW configurations on each BWP. If there is a BWP#4 on the CC#1, a BWP#5 on the CC#2 and a BWP#6 on the CC#3, but there is no same second specified parameter of the PPW on these BWPs. In this case, if the three CCs need to be aggregated to send PRS, the three BWPs (BWP#1, #2, #3) on the three CCs can only be activated to do aggregation, because other BWPs can not have the same PPW configuration.

[0253] In some embodiments, after receiving the RRC signaling sent by the network side device, the terminal device can further receive indication information sent by the network side device, wherein the RRC signaling is used to configure the PPW on the plurality of CCs, the plurality of CCs are used to simultaneously transmit PRS, and the indication information is used to indicate to activate the PRS processing window PPW on the plurality of component carriers CCs.

[0254] In some embodiments, after receiving the RRC signaling sent by the network side device and receiving the indication information sent by the network side device, the terminal device can further measure the PRS on the plurality of CCs within a single time instance in the PPW, wherein the RRC signaling is used to configure the PPW on the plurality of CCs, the plurality of CCs are used to simultaneously transmit PRS, and the indication information is used to indicate to activate the PRS processing window PPW on the plurality of component carriers CCs.

[0255] It should be noted that the related description of the terminal device receiving the indication information sent by the network side device and the method of the terminal device measuring the PRS on the plurality of CCs within a single time instance in the PPW can be referred to the related description in the above embodiments, which will not be repeated here.

[0256] It should be noted that in the embodiments of the present disclosure, S41 can be implemented alone or in combination with any other step in the embodiments of the present disclosure, for example, in combination with S21 and / or S31 and S32 in the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitations in this regard.

[0257] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with other embodiments or examples, without contradiction.

[0258] By implementing the embodiments of the present disclosure, the terminal device receives the RRC signaling sent by the network side device, wherein the RRC signaling is used to configure the PPW on the plurality of CCs, and the plurality of CCs are used to simultaneously transmit PRS. Therefore, the terminal device can determine the PPW on the plurality of CCs used to simultaneously transmit PRS.

[0259] Please refer to Figure 5 , Figure 5 is a flowchart of another method for activating a positioning reference signal (PRS) processing window (PPW) provided by an embodiment of the present disclosure. As shown in Figure 5 , the method is performed by a network side device, and the method can include but is not limited to the following steps:

[0260] S51: sending indication information to the terminal device, wherein the indication information is used to indicate the activation of the PPW on the plurality of component carriers (CCs).

[0261] In an embodiment of the present disclosure, the network side device can send the indication information to the terminal device, and the indication information is used to indicate the activation of the PPW on the plurality of CCs. Therefore, the indication information can activate the PPW on the plurality of CCs at the same time, and the signaling overhead can be saved.

[0262] It should be noted that the CC in all embodiments of the present disclosure can be replaced by a positioning frequency layer (PFL).

[0263] In the case of configuring the terminal device to perform PRS transmission based on the plurality of CCs, the indication information can be sent to the terminal device, and the indication information is used to indicate the activation of the PPW on the plurality of CCs.

[0264] In some embodiments, the network side device sends the indication information to the terminal device, including: sending a MAC CE to the terminal device, wherein the MAC CE includes the indication information.

[0265] In an embodiment of the present disclosure, the network side device can send the MAC CE to the terminal device, and the MAC CE includes the indication information, and the indication information is used to indicate the activation of the PPW on the plurality of CCs.

[0266] In some embodiments, the activated PPW on the plurality of CCs corresponds to the same first specified parameter, wherein the first specified parameter includes at least one of the following:

[0267] PPW identifier;

[0268] entry of the PPW in the PPW list;

[0269] time domain location information of the PPW;

[0272] a priority corresponding to the PRS.

[0273] In the embodiments of the present disclosure, the indication information is used to indicate the activated PPW on multiple CCs, wherein the activated PPW on the multiple CCs corresponds to the same first specified parameter.

[0274] In the embodiments of the present disclosure, the first specified parameter can be a PPW identifier. It can be understood that the PPW identifier (ID) can be a PPW identifier configured by the network side device through RRC signaling. When the network side device deactivates the PPW through the MAC CE, the PPW ID indicated in the MAC CE corresponds to the PPW ID configured by the network side device through RRC.

[0275] In the embodiments of the present disclosure, the first specified parameter can be an entry in a PPW list corresponding to the PPW.

[0276] It can be understood that the entry in the PPW list can be an entry in the PPW list configured by the network side device through RRC. When the network side device deactivates the PPW through the MAC CE, the PPW ID indicated in the MAC CE corresponds to the entry of the PPW in the PPW list configured by the network side device through RRC.

[0277] In the embodiments of the present disclosure, the first specified parameter can be time domain location information of the PPW.

[0278] The time domain location information of the PPW can include at least one of a period of the PPW, a starting slot position, and a starting slot in the PPW.

[0279] In the embodiments of the present disclosure, the first specified parameter can be a length of the PPW.

[0280] The length of the PPW can be a number of slots occupied by the PPW, or a number of slots occupied by each of the PPWs in the case of multiple PPWs with periodicity, and the like.

[0281] In the embodiments of the present disclosure, the first specified parameter can be a type corresponding to the PRS.

[0282] The type corresponding to the PRS can be a type when the PRS priority is high.

[0283] Exemplarily, the type can refer to whether the terminal device affects one CC or multiple CCs within the PPW, or whether the PRS is in a symbol or the PPW is in a symbol.

[0284] In some embodiments, the type corresponding to the PRS includes at least one of the following:

[0285] Type 1: PRS has high priority over downlink channels / signals in all symbols within the PPW. (PRS has priority over all other downlink signals / channels in all symbols inside the window.)

[0286] Type 1A: PRS has high priority over downlink channels / signals on all CCs of the terminal device. (The DL signals / channels from all DL CCs (per UE) are affected.)

[0287] Type 1B: PRS has high priority over downlink channels / signals on a specified band of the terminal device, such as the band where the PRS is located. (Only the DL signals / channels from a certain band are affected.)

[0288] Type 2: PRS has high priority only over downlink channels / signals in the symbols where the PRS is located. (PRS has priority over other DL signals / channels only in the PRS symbols inside the window.)

[0289] In the embodiments of the present disclosure, the first specified parameter can be a priority corresponding to the PRS.

[0290] The priority corresponding to the PRS indicates the priority between the PRS and the PDCCH / PDSCH / CSI-RS.

[0291] Exemplarily, the priority corresponding to the PRS includes at least one of the following states:

[0292] State 1: PRS is higher priority than all DL channel / signal except SSB. (State 1: PRS is higher priority than all DL channel / signal except SSB.) i.e. including PDCCH / PDSCH / DMRS / CSI-RS.

[0293] State 2: PRS is lower priority than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other DL signals / channels except SSB. (State 2: PRS is lower priority than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other DL signals / channels except SSB.)

[0294] State 3: PRS is lower priority than all the DL signals / channels except SSB. (State 3: PRS is lower priority than all the DL signals / channels except SSB.)

[0295] It should be noted that if the PRS priority is high, the terminal device receives the PRS, otherwise it does not receive the PRS.

[0296] It should be noted that the above embodiments are not exhaustive, only part of the embodiments are shown, and the above embodiments can be implemented alone, or can be combined with multiple embodiments, the above embodiments are only used as an example, and not as a specific limitation on the protection scope of the embodiments of the present disclosure.

[0303] In the embodiments of the present disclosure, the indication information is used to indicate to activate the PPWs on the multiple CCs, and the indication information includes the PPW identification. In this case, the indication information can be used to indicate to activate the PPWs corresponding to the PPW identification on each of the multiple CCs.

In this case, the indication information can be used to activate the PPWs corresponding to the first PPW identification on each of the multiple CCs, and the first PPW identification is the PPW identification corresponding to the entry in the PPW list on the specified CC.

[0308] In a possible implementation, the indication information can be used to activate the PPWs corresponding to the first PPW identification on each of the multiple CCs, and the first PPW identification is the PPW identification corresponding to the entry in the PPW list on the specified CC. When the indication information contains the cell identification, the specified CC is the CC corresponding to the cell identification. When the indication information does not contain the cell identification, the specified CC is the CC with the smallest CC identification in the multiple CCs corresponding to the PRS.

[0309] In the embodiments of the present disclosure, the indication information is used to indicate to activate the PPWs on the multiple CCs, and the indication information includes the cell identification. In this case, the indication information can be used to indicate to activate the PPWs on at least one CC corresponding to the cell identification in the multiple CCs. It can be understood that the cell identification includes the cell ID or the CC ID.

[0310] In a possible implementation, the indication information can be used to indicate to activate the PPWs on at least one CC corresponding to the cell identification in the multiple CCs.

[0311] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the multiple CCs, and the indication information includes a BWP identifier. In this case, the indication information can be used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the multiple CCs. Or the indication information does not include the BWP identifier, and the indication information is used to indicate the PPW on the active BWP on at least one of the multiple CCs.

[0312] In a possible implementation, the indication information can be used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the multiple CCs. Or the indication information can be used to indicate the PPW on the active BWP on at least one of the multiple CCs.

[0313] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the multiple CCs, and the indication information includes multi-CC indication information. In this case, the indication information can be used to indicate the PPW on the multiple CCs indicated by the multi-CC indication information.

[0314] In a possible implementation, the indication information can be used to indicate the PPW on the BWP on the multiple CCs indicated by the multi-CC indication information.

[0315] It should be noted that the above embodiments are not exhaustive, but only illustrate some embodiments, and the above embodiments can be implemented alone or in combination. The indication information can include multiple ones of the PPW identifier, the entry corresponding to the PPW in the PPW list, the cell identifier, the multi-CC indication information, and the BWP identifier. The above embodiments are only illustrative and not used to limit the protection scope of the embodiments of the present disclosure.

[0316] For example, the indication information includes the PPW identifier and the cell identifier. In this case, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the CC corresponding to the cell identifier among the multiple CCs.

[0317] For example, the indication information includes the PPW identifier, the cell identifier, and the BWP identifier. In this case, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the BWP corresponding to the BWP identifier on at least one of the CCs corresponding to the cell identifier among the multiple CCs.

[0318] In some embodiments, the multi-CC indication information includes at least one of the following:

[0319] CC list information including multiple CCs;

[0320] Information used to indicate whether the indication information is applicable to multiple CCs.

[0321] In the embodiments of the present disclosure, the multi-CC indication information can comprise: CC list information comprising a plurality of CCs.

[0322] The CC list information can comprise an ID of the CC list. The information of the CC corresponding to the CC list ID can be obtained through RRC configuration information of the network device or based on a default rule specified by a protocol. The CC list can comprise a plurality of CC identifiers corresponding to the CCs.

[0323] For example, the numbering of the CC identifier can be numbered from all the serving cells corresponding to the terminal device configuration, not only from the plurality of CCs corresponding to the PRS, such as CC#3 and CC#4, but also from the CC#1, CC#2 and CC#5 corresponding to other communications of the terminal device (of course, the other communications can also use CC#3 and CC#4, and here, it is only illustrated that the other communications can also comprise CCs other than the CCs occupied by the PRS); in this case, the numbering of the CC identifier is numbered from the 5 CCs, and if numbered from 0, 3 bits of each CC identifier in the RRC signaling are required, so that the numbering of each CC can be determined according to the 3-bit identifier corresponding to the 5 CCs.

[0324] For example, the numbering of the CC identifier can be numbered from the CCs corresponding to the PRS of the terminal device, excluding the CCs not occupied by the PRS. For example, the CC#3 and CC#4 corresponding to the PRS, and the CC#1, CC#2 and CC#5 corresponding to other communications of the terminal device (of course, the other communications can also use CC#3 and CC#4), in this case, the numbering of the CC identifier is numbered from the 2 CCs corresponding to the PRS, and if numbered from 0, 1 bit of each CC identifier in the RRC signaling is required, so that the numbering of each CC can be determined according to the 1-bit identifier corresponding to the 2 CCs.

[0325] In the embodiments of the present disclosure, the multi-CC indication information can comprise: information for indicating whether the indication information is applicable to a plurality of CCs.

[0326] The information for indicating whether the indication information is applicable to a plurality of CCs can be 1-bit information.

[0327] For example, in the case of 1 of the 1-bit information, it can be indicated that the indication information is applicable to a plurality of CCs, for example, applicable to the plurality of CCs included in the CC list information, and in the case of 0 of the 1-bit information, it can be indicated that the indication information is not applicable to a plurality of CCs, for example, not applicable to the plurality of CCs included in the CC list information. Here, the CC list can be defaulted to contain all the CCs used for PRS transmission.

[0328] It should be noted that the above embodiments are not exhaustive, and only some embodiments are shown, and the above embodiments can be implemented alone or in combination, and the above embodiments are only illustrative and not as a specific limitation on the protection scope of the embodiments of the present disclosure.

[0329] In some embodiments, if the indication information includes the BWP identifier, the indication information is used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the plurality of CCs; or if the indication information does not include the BWP identifier, the indication information is used to indicate the PPW on the activated BWP on at least one of the plurality of CCs.

[0330] In the embodiments of the present disclosure, in the case where the indication information includes the BWP identifier, the indication information can be used to indicate the PPW on the BWP corresponding to the BWP identifier on at least one of the plurality of CCs.

[0331] In the embodiments of the present disclosure, in the case where the indication information does not include the BWP identifier, the indication information can be used to indicate the PPW on the activated BWP on at least one of the plurality of CCs.

[0332] In some embodiments, in the case where the indication information includes an entry in the PPW list corresponding to the PPW, the indication information is used to indicate the PPW corresponding to the entry in the PPW list on each of the plurality of CCs.

[0333] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes an entry in the PPW list corresponding to the PPW, the indication information can be used to indicate the PPW corresponding to the entry in the PPW list on each of the plurality of CCs.

[0334] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes an entry in the PPW list corresponding to the PPW, the indication information can be used to indicate the PPW corresponding to the entry in the PPW list on the activated BWP on each of the plurality of CCs.

[0335] Optionally, the indication information is used to indicate to activate the PPWs on multiple CCs, in case that the indication information includes entries in a PPW list corresponding to the PPWs, the PPWs on multiple CCs can all be the PPWs configured by the entries (entries in the PPW list) contained in the MAC CE. Because the PPW list on each BWP of each cell is configured independently, i.e., the MAC CE can activate the PPW configuration of the PPW entry such as entry #0 on multiple CCs, i.e., the cell ID of the MAC CE is ignored, but is applicable to multiple cell IDs. However, the prerequisite of this method is that the specified parameters of the PPW with entry #0 in the PPW list on different BWP of multiple CCs configured by RRC are the same, of course, it can also include different cases.

[0336] That is, the MAC CE indicates the entries corresponding to multiple PPWs in the PPW list configured by RRC in the BWP. For example, the RRC configuration is as follows:

[0337] The PPW list of BWP #1 of CC #1 contains four PPWs,

[0338] The first PPW ID is ID #2, and the corresponding entry is #0;

[0339] The second PPW ID is ID #4, and the corresponding entry is #1;

[0340] The third PPW ID is ID #5, and the corresponding entry is #2;

[0341] The fourth PPW ID is ID #6, and the corresponding entry is #3;

[0342] For example, the PPW list of BWP #2 of CC #2 contains four PPWs,

[0343] The first PPW ID is ID #1, and the corresponding entry is #0;

[0344] The second PPW ID is ID #2, and the corresponding entry is #1;

[0345] The third PPW ID is ID #5, and the corresponding entry is #2;

[0346] The fourth PPW ID is ID #4, and the corresponding entry is #3;

[0347] In the above example, the same PPW ID indicates the same PPW.

[0348] In an embodiment, if the entry in the PPW list contained in the MAC CE is #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #2 on the active BWP #1 of CC#1, and activates the PPW with PPW ID #1 on the active BWP #2 of CC#2. It can be understood that the PPWs activated by the MAC CE on the two CCs are different.

[0349] In another embodiment, if the entry in the PPW list contained in the MAC CE is #2, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #5 on the active BWP #1 of CC#1, and activates the PPW with PPW ID #5 on the active BWP #2 of CC#2. It can be understood that the PPWs activated by the MAC CE on the two CCs are the same.

[0350] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on multiple CCs, and in the case that the indication information includes the entry in the PPW list corresponding to the PPW and the BWP identifier, the indication information can be used to indicate the activation of the PPW corresponding to the entry in the PPW list on the BWP corresponding to the BWP identifier on each of the multiple CCs.

[0351] In some embodiments, in the case that the indication information includes the entry in the PPW list corresponding to the PPW, the indication information is used to indicate the activation of the PPW corresponding to the first PPW identifier on each of the multiple CCs, and the first PPW identifier is the PPW identifier corresponding to the entry in the PPW list on the specified CC. When the indication information contains the cell identifier, the specified CC is the CC corresponding to the cell identifier; when the indication information does not contain the cell identifier, the specified CC is the CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0352] In the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on multiple CCs, and in the case that the indication information includes the entry in the PPW list corresponding to the PPW, the indication information can be used to indicate the activation of the PPW corresponding to the first PPW identifier on each of the multiple CCs, and the first PPW identifier is the PPW identifier corresponding to the entry in the PPW list on the specified CC. When the indication information contains the cell identifier, the specified CC is the CC corresponding to the cell identifier; when the indication information does not contain the cell identifier, the specified CC is the CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0353] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs, the indication information can be used to indicate the activation of the PPW corresponding to a first PPW identifier on a BWP activated on each of the multiple CCs, the first PPW identifier being a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0354] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs and a BWP identifier, the indication information can be used to indicate the activation of the PPW corresponding to a first PPW identifier on a BWP corresponding to the BWP identifier on each of the multiple CCs, the first PPW identifier being a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS.

[0355] Optionally, the indication information is used to indicate the activation of the PPWs on the multiple CCs, and in the case that the indication information includes an entry in a PPW list corresponding to the PPWs, the PPWs activated on the multiple CCs can all be the PPW corresponding to a first PPW identifier. The first PPW identifier is a PPW identifier corresponding to an entry in a PPW list on a specified CC. When the indication information contains a cell identifier, the specified CC is a CC corresponding to the cell identifier; when the indication information does not contain a cell identifier, the specified CC is a CC with the smallest CC identifier in the multiple CCs corresponding to the PRS. Because the PPW list on each BWP of each cell is independently configured, i.e., the MAC CE can activate the PPW ID #0 on the multiple CCs, i.e., the cell identifier of the MAC CE is ignored, and is applicable to multiple cell IDs. However, the premise of this method is that the PPW ID #0 corresponding PPW is contained in the RRC configured PPW list on the BWP of each of the multiple CCs.

[0356] That is, the MAC CE indicates the entries of the multiple PPWs in the RRC configured PPW list in the BWP. For example, the RRC configuration is as follows:

[0357] The PPW list of the activated BWP #1 of the CC #1 contains four PPWs,

[0358] The first PPW ID is ID#2, and the corresponding entry is #0;

[0359] The second PPW ID is ID#4, and the corresponding entry is #1;

[0360] The third PPW ID is ID#5, and the corresponding entry is #2;

[0361] The fourth PPW ID is ID#6, and the corresponding entry is #3;

[0362] The PPW list of the activated BWP#2 of CC#2 contains four PPWs,

[0363] The first PPW ID is ID#1, and the corresponding entry is #0;

[0364] The second PPW ID is ID#2, and the corresponding entry is #1;

[0365] The third PPW ID is ID#5, and the corresponding entry is #2;

[0366] The fourth PPW ID is ID#4, and the corresponding entry is #3;

[0367] In the above example, the same PPW ID indicates the same PPW.

[0368] In an embodiment, if the entry in the PPW list contained in the MAC CE is #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier, and the cell identifier is CC#1. Therefore, it is equivalent to that the MAC CE activates the PPW with the PPW ID of #2 (i.e., the first PPW identifier is PPW ID#2) on the activated BWP#1 of CC#1, and also activates the PPW with the PPW ID of #2 on the activated BWP#2 of CC#2. That is, regardless of whether the entry in the PPW list corresponding to the PPW with the PPW ID of #2 on the activated BWP of CC#2 is #0, the MAC CE activates the PPW with the PPW ID of #2 on the BWP of each CC. It can be understood that the PPW activated by the MAC CE on the two CCs is the same. In this case, it is also required that the PPW corresponding to the first PPW identifier is contained in the PPW list on the BWP of CC#2.

[0369] In an embodiment, if the entry in the PPW list contained in the MAC CE is #1, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain the BWP identifier, and the cell identifier is CC#1. Therefore, it is equivalent to the MAC CE activating the PPW with PPW ID #4 (i.e., the first PPW identifier is PPW ID #4) on the active BWP #1 of CC#1, and also activating the PPW with PPW ID #4 on the active BWP #2 of CC#2. That is, regardless of whether the entry in the PPW list corresponding to the PPW with PPW ID #4 on the active BWP of CC#2 is #1, the MAC CE activates the PPW with PPW ID #4 on the BWP of each CC. It can be understood that the PPW activated by the MAC CE on the two CCs is the same. In this case, it is also required that the PPW corresponding to the first PPW identifier is contained in the PPW list on the BWP of CC#2.

[0370] In some embodiments, in the case where the indication information includes the PPW identifier, the indication information is used to indicate the PPW corresponding to the PPW identifier on each of the plurality of CCs.

[0371] In the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on each of the plurality of CCs.

[0372] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the active BWP of each of the plurality of CCs.

[0373] Optionally, in the embodiments of the present disclosure, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier and the BWP identifier, the indication information can be used to indicate the PPW corresponding to the PPW identifier on the BWP corresponding to the BWP identifier on each of the plurality of CCs.

[0374] Optionally, the indication information is used to indicate the PPW on the plurality of CCs, and in the case where the indication information includes the PPW identifier, the PPW on the plurality of CCs can all be the PPW corresponding to the PPW identifier. Because the PPW list on each BWP of each cell is independently configured, i.e., the MAC CE can activate the PPW with PPW ID #0 on the plurality of CCs, i.e., the cell identifier of the MAC CE is ignored, and is applicable to multiple cell IDs. However, the premise of this method is that the PPW corresponding to PPW ID #0 is contained in the PPW list on the BWP of each of the plurality of CCs configured by RRC.

[0375] That is, the MAC CE indicates the entries corresponding to multiple PPWs in the RRC configured PPW list in the BWP. For example, the RRC configuration is as follows:

[0376] The PPW list of the activated BWP#1 of CC#1 contains four PPWs,

[0377] The first PPW ID is ID#2, and the corresponding entry is #0;

[0378] The second PPW ID is ID#4, and the corresponding entry is #1;

[0379] The third PPW ID is ID#5, and the corresponding entry is #2;

[0380] The fourth PPW ID is ID#6, and the corresponding entry is #3;

[0381] The PPW list of the activated BWP#2 of CC#2 contains four PPWs,

[0382] The first PPW ID is ID#1, and the corresponding entry is #0;

[0383] The second PPW ID is ID#2, and the corresponding entry is #1;

[0384] The third PPW ID is ID#5, and the corresponding entry is #2;

[0385] The fourth PPW ID is ID#4, and the corresponding entry is #3;

[0386] In the above example, the same PPW ID indicates the same PPW.

[0387] In an embodiment, if the MAC CE contains PPW ID #0, the multi-CC indication information indicates that it is applicable to CC#1 and CC#2, and does not contain BWP ID. Therefore, it is equivalent to that the MAC CE activates the PPW with PPW ID #0 on the activated BWP#1 of CC#1, and activates the PPW with PPW ID #0 on the activated BWP#2 of CC#2. That is, the MAC CE directly indicates the PPW ID corresponding to the RRC configured PPW, rather than the entry in the RRC configured PPW list. It can be understood that the PPWs on the two CCs activated by the MAC CE are the same. In this case, it is also required that the PPW list on at least one BWP of each of the multiple CCs contains at least the PPW corresponding to the same PPW ID.

[0388] In the embodiments or examples, each step can be independent, arbitrarily combined or exchanged in sequence without contradiction, and optional modes or examples can be arbitrarily combined and combined with other embodiments or examples.

[0389] By implementing the embodiments of the present disclosure, the network side device sends a MAC CE to the terminal device, wherein the MAC CE includes indication information. In this way, the indication information can activate the PPW on multiple CCs at the same time, and the signaling overhead can be saved.

[0390] Please refer to Figure 6 , Figure 6 is another flowchart of a method for configuring a positioning reference signal (PRS) processing window (PPW) provided by the embodiments of the present disclosure. As shown in Figure 6 , the method is performed by a network side device, and the method can include but is not limited to the following steps:

[0391] S61: sending RRC signaling to the terminal device, wherein the RRC signaling is used to configure the PPW on multiple CCs, and the multiple CCs are used to simultaneously transmit PRS.

[0392] In the embodiments of the present disclosure, the network side device can send RRC signaling to the terminal device, and the RRC signaling is used to configure the PPW on multiple CCs, thereby indicating the terminal device to determine the PPW on multiple CCs.

[0393] , wherein the multiple CCs are used to simultaneously transmit PRS.

[0394] In some embodiments, the RRC signaling is used to configure a PPW list on at least one BWP respectively included by the multiple CCs, and each PPW list includes at least one PPW.

[0395] In the embodiments of the present disclosure, the RRC signaling is used to configure a PPW list on at least one BWP respectively included by the multiple CCs, and each PPW list includes at least one PPW. In this way, the terminal device can be instructed to determine the PPW on multiple CCs.

[0396] In some embodiments, the RRC signaling is used to configure a second designated parameter of the PPW, and the second designated parameter of at least one PPW on at least one BWP respectively included by the multiple CCs is the same; wherein the second designated parameter includes at least one of the following:

[0397] PPW identifier;

[0398] entry of the PPW in the PPW list;

[0399] time domain location information of the PPW;

[0400] length of the PPW;

[0401] a type corresponding to the PRS;

[0402] a priority corresponding to the PRS.

[0403] In the embodiments of the present disclosure, the RRC signaling can also configure a second designated parameter of the PPW. Wherein, the second designated parameter corresponding to at least one PPW on at least one BWP in the plurality of CCs is the same.

[0404] In the embodiments of the present disclosure, the second designated parameter can include a PPW identifier. It can be understood that the PPW identifier (ID) can be the PPW identifier configured by the network side device through the RRC signaling.

[0405] In the embodiments of the present disclosure, the second designated parameter can include an entry of the PPW in the PPW list.

[0406] In the embodiments of the present disclosure, the second designated parameter can include time domain location information of the PPW.

[0407] Wherein, the time domain location information of the PPW can include at least one of a period, a starting slot position, and a starting slot of the PPW.

[0408] In the embodiments of the present disclosure, the second designated parameter can include a length of the PPW.

[0409] Wherein, the length of the PPW can be the number of slots occupied by the PPW, or the number of slots occupied by each PPW in the case of multiple PPWs with periodicity, etc.

[0410] In the embodiments of the present disclosure, the second designated parameter can include a type corresponding to the PRS.

[0411] Wherein, the type corresponding to the PRS can be a type when the PRS priority is high.

[0412] Exemplarily, the type can refer to whether the terminal device affects one CC or multiple CCs within this PPW, or whether the PRS is in a symbol or the PPW is in a symbol.

[0413] In some embodiments, the type corresponding to the PRS includes at least one of:

[0414] Type 1: If the PRS priority is high, the priority of the PRS is higher than the downlink channel / signal on all symbols within the PPW. (The PRS has priority over all other downlink signals / channels in all symbols within the window.)

[0415] Type 1A: PRS has higher priority than downlink channels / signals on all CCs of the terminal device. (The DL signals / channels from all DL CCs (per UE) are affected.)

[0416] Type 1B: PRS has higher priority than downlink channels / signals on a specified band of the terminal device, such as the band where PRS is located. (Only the DL signals / channels from a certain band are affected.)

[0417] Type 2: If PRS has higher priority, it is only higher than downlink channels / signals on the symbols where PRS is located. (PRS prioritization over other DL signals / channels only in the PRS symbols inside the window.)

[0418] In the embodiments of the present disclosure, the second specified parameter can include a priority corresponding to the PRS.

[0419] The priority corresponding to the PRS indicates the priority between the PRS and the PDCCH / PDSCH / CSI-RS.

[0420] Exemplarily, the priority corresponding to the PRS includes at least one of the following states:

[0421] State 1: The priority of the PRS is higher than all downlink channels / signals, except for the Synchronization Signal Block (SSB). (State 1: PRS is higher priority than all DL channel / signal except SSB.) That is, including PDCCH / PDSCH / DMRS / CSI-RS.

[0422] State 2: PRS is lower priority than PDCCH and the PDSCH scheduled by DCI formats 1_1 or 1_2 with the priority indicator field in the corresponding DCI format set to 1, and is higher priority than other DL signals / channels except SSB.

[0423] State 3: PRS is lower priority than all the DL signals / channels except SSB.

[0424] It should be noted that if the PRS priority is high, the terminal device receives the PRS, otherwise it does not receive the PRS.

[0425] It should be noted that the above embodiments are not exhaustive, only part of the embodiments are shown, and the above embodiments can be implemented alone or in combination with multiple embodiments. The above embodiments are only used as an example and do not limit the protection scope of the embodiments of the present disclosure.

[0426] For example, the BWP#1 of CC#1, the BWP#2 of CC#2, and the BWP#3 of CC#3 have a PPW configuration corresponding to the same second designated parameter, and each BWP can have other PPW configurations. If there is BWP#4 on CC#1, BWP#5 on CC#2, and BWP#6 on CC#3, but there is no same second designated parameter on these BWP PPWs. In this case, if the three CCs need to be aggregated to transmit PRS, the three BWP (BWP#1, #2, #3) on the three CCs can only be activated for aggregation, because other BWP may not have the same PPW configuration.

[0427] In some embodiments, after the network-side device sends the RRC signaling to the terminal device, the network-side device can further send indication information to the terminal device, where the RRC signaling is used to configure the PPW on the plurality of CCs, and the plurality of CCs are used to simultaneously transmit PRS, and the indication information is used to indicate to activate the PPW on the plurality of component carriers CCs.

[0428] It should be noted that the above description of the method for the network-side device to send the indication information to the terminal device can refer to the related description in the above embodiments, which will not be repeated here. In addition, the related description of the indication information can refer to the related description in the above embodiments, which will not be repeated here.

[0429] It should be noted that in the embodiments of the present disclosure, S61 can be implemented alone or in combination with any other step in the embodiments of the present disclosure, such as in combination with S51 in the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitations.

[0430] In the present embodiment or example, each step can be independently combined or exchanged in order without contradiction, and optional modes or examples can be combined with other embodiments or examples.

[0431] By implementing the embodiments of the present disclosure, the network-side device sends RRC signaling to the terminal device, where the RRC signaling is used to configure the PPW on the plurality of CCs, and the plurality of CCs are used to simultaneously transmit PRS. Thus, the network-side device can configure the PPW on the plurality of CCs for the terminal device to simultaneously transmit PRS.

[0432] In order to facilitate the understanding of the embodiments of the present disclosure, the embodiments of the present disclosure provide the following exemplary embodiments. The embodiments of the present disclosure propose a MAC CE activation method for PPW on each BWP on a plurality of CCs, which can reduce the signaling overhead of PPW activation on a plurality of CCs in a carrier aggregation scenario.

[0433] In the exemplary embodiments, the terminal device can receive a MAC CE, and the MAC CE is used to activate the PPW, and the terminal device is configured to perform PRS transmission based on a plurality of CCs.

[0434] Optionally, the MAC CE is used to activate the PPW on the plurality of CCs.

[0435] Optionally, the PPW on the plurality of CCs corresponds to the same first specified parameter.

[0436] The first specified parameter can include at least one of an RRC configured PPW ID, a PPW time domain location (i.e., a PPW period and a starting slot), a length (a number of slots occupied by the PPW), a type (a type when a PRS priority is high), and a priority (a priority of the PRS relative to PDCCH / PDSCH / CSI-RS).

[0437] In some embodiments, the MAC CE includes a PPW identification (PPW ID) and a cell identification (Cell ID), and multi-CC indication information.

[0438] Optionally, the MAC CE can also include a BWP identification (BWP ID), and in the case where the BWP ID is not included, the BWP is an active BWP on each CC. In the case where the BWP ID is included, the BWP is a BWP corresponding to the BWP ID on each CC.

[0439] In some embodiments, the PPW ID included in the MAC CE can actually be an entry in a PPW list (PPW list), and the PPW ID 0 corresponds to a PPW corresponding to the first entry in the PPW list. For the convenience of description, the PPW ID of the MAC CE in the following is written as an entry in the PPW list (or written as a PPW entry).

[0440] Optionally, the entry in the PPW list and the cell ID are used to indicate that the parameter corresponding to the activated PPW is the active BWP on the cell corresponding to the cell ID or the PPW parameter in the entry in the PPW list on the BWP ID.

[0441] In some embodiments, the multi-CC indication information can be at least one of the following:

[0442] CC list information including a plurality of CCs, wherein the CC list can include a CC identification corresponding to each of the plurality of CCs.

[0443] Information for indicating whether the indication information is applicable to a plurality of CCs.

[0444] The CC list information includes a plurality of CCs, wherein the CC list can include a CC identification corresponding to each of the plurality of CCs.

[0445] Exemplarily, the numbering of the CC identifier can be numbered from all serving cells corresponding to the terminal device configuration, not only from the multiple CCs corresponding to the PRS, such as CC#3 and CC#4, but also from the CCs #1, #2 and #5 corresponding to other communications of the terminal device (of course, the other communications can also use CC#3 and CC#4, and here, it is only illustrated that the other communications can also include the CCs other than the CCs occupied by the PRS); in this case, the numbering of the CC identifier is numbered from the 5 CCs, and if numbered from 0, 3 bits of each CC identifier in the RRC signaling are required, and thus the numbering of each CC can be determined according to the 3-bit identifier corresponding to the 5 CCs.

[0446] Exemplarily, the numbering of the CC identifier can be numbered from the CCs corresponding to the PRS of the terminal device, and the CCs not occupied by the PRS are not included. For example, the CCs #3 and #4 corresponding to the PRS, and the CCs #1, #2 and #5 corresponding to other communications of the terminal device (of course, the other communications can also use CC#3 and CC#4), in this case, the numbering of the CC identifier is numbered from the 2 CCs corresponding to the PRS, and if numbered from 0, 1 bit of each CC identifier in the RRC signaling is required, and thus the numbering of each CC can be determined according to the 1-bit identifier corresponding to the 2 CCs.

[0447] In the embodiments of the present disclosure, the multi-CC indication information can include information for indicating whether the indication information is applicable to multiple CCs.

[0448] The information for indicating whether the indication information is applicable to multiple CCs can be 1-bit information.

[0449] Exemplarily, in the case of 1 of the 1-bit information, it can be indicated that the indication information is applicable to multiple CCs, for example, applicable to the multiple CCs included in the CC list information, and in the case of 0 of the 1-bit information, it can be indicated that the indication information is not applicable to multiple CCs, for example, not applicable to the multiple CCs included in the CC list information.

[0450] In this case, it can be understood that activating the PPW on multiple CCs is the PPW configuration corresponding to the PPW entry contained in the MAC CE. Because the PPW list on each BWP of each cell is independently configured, that is, the MAC CE can activate the PPW configuration of the PPW entry such as entry #0 on multiple CCs, that is, ignore the cell ID of the MAC CE, but is applicable to multiple cell IDs. However, the premise of this method is that the specified parameters of the PPW with entry #0 in the PPW list on different BWP of multiple CCs configured by RRC are the same, of course, it can also include different cases.

[0451] That is, the PPW ID indicated by the MAC CE is actually the entry corresponding to multiple PPWs in the PPW list configured by RRC in the BWP. For example, the PPW list of BWP #1 of CC #1 contains four PPWs, the first PPW ID is ID #2, and the corresponding entry is #0; the second PPW ID is ID #4, and the corresponding entry is #1; the third PPW ID is ID #5, and the corresponding entry is #2; the fourth PPW ID is ID #6, and the corresponding entry is #3; for example, the PPW list of BWP #2 of CC #2 contains four PPWs, the first PPW ID is ID #1, and the corresponding entry is #0; the second PPW ID is ID #2, and the corresponding entry is #1; the third PPW ID is ID #5, and the corresponding entry is #4; the fourth PPW ID is ID #5, and the corresponding entry is #3; and the PPW ID of the MAC CE indicates the entry of the PPW in the list, not the RRC configured PPW ID.

[0452] For example, the PPW list of BWP #1 of CC #1 contains four PPWs,

[0453] The first PPW ID is ID #2, and the corresponding entry is #0;

[0454] The second PPW ID is ID #4, and the corresponding entry is #1;

[0455] The third PPW ID is ID #5, and the corresponding entry is #2;

[0456] The fourth PPW ID is ID #6, and the corresponding entry is #3;

[0457] For example, the PPW list of BWP #2 of CC #2 contains four PPWs,

[0458] The first PPW ID is ID#1, and the corresponding entry is #0;

[0459] The second PPW ID is ID#2, and the corresponding entry is #1;

[0460] The third PPW ID is ID#5, and the corresponding entry is #2;

[0461] The fourth PPW ID is ID#4, and the corresponding entry is #3;

[0462] In the above example, the same PPW ID indicates the same PPW.

[0463] Optionally, the PPWs corresponding to the entries activated by the MAC CE on multiple CCs are the same. Because the MAC CE contains a PPW entry, such as PPW entry #1, and this MAC CE is applicable to CC#1 and CC#2 at the same time, for CC#1, the PPW of PPW entry #1 is the PPW of PPW ID#4, that is, the PPW of PPW ID#4 is activated on CC#1. For CC#2, the PPW of PPW entry #1 is the PPW of PPW ID#2, that is, the PPW of PPW ID#4 is activated on CC#2. Obviously, this cannot achieve our purpose. If we want to achieve our purpose, we need the PPW IDs corresponding to the entries activated on the two CCs to be the same. For example, the MAC CE indicates that the PPW entry is 2, and the PPW of PPW ID#5 is activated, that is, the purpose is achieved. Therefore, this method requires that at least one entry in the PPW list of multiple CCs configured by RRC has the same PPW ID.

[0464] Optionally, the MAC CE indicates CC ID#1, PPW entry#1, and the MAC CE activates the PPW of PPW entry#1, that is, the PPW of PPW ID#4. At the same time, if the MAC CE also indicates that it is applicable to CC#2, then CC#2 also activates the PPW of PPW ID#4, regardless of whether the entry corresponding to PPW ID#4 on CC#2 is 1. In this case, only the PPW list of CC#2 needs to have PPW ID#4.

[0465] In this case, it can be understood that the PPW entry corresponding to the PPW configuration indicated by the activated MAC CE is on the cell ID. For other cells, the same PPW configuration is activated, but whether the PPW entry corresponding to the same PPW configuration on the other cells, i.e., the entry in the PPW list, is the same PPW entry, can be ignored. For example, the CC ID in the above-mentioned MAC CE is CC#1, the PPW ID, i.e., the PPW entry, is #0, i.e., the PPW corresponding to the RRC PPW ID ID#2 is activated. For CC#2, the PPW corresponding to the RRC PPW ID ID#2 is also activated, although the PPW entry is not #0 but #1. Therefore, the premise of this method is that as long as there is a PPW with the same PPW specified parameter on multiple CCs, it is not necessary to require that the entry in the PPW list is the same, so that the RRC configuration is more flexible.

[0466] In some embodiments, the terminal device can measure multiple CCs (or PFLs) within an instance of a PPW.

[0467] Because the PPW occurs periodically and only once in a period, the length of time occupied is the number of slots indicated by the length, i.e., in the PPW occurring once in each period, only one CC or one PRS frequency layer can be measured in the related method, but different CCs or different PFLs can be measured in the PPW occurring in different periods. However, in the case of carrier aggregation, it is necessary to support the measurement of multiple CCs or multiple PFLs on PRS within the PPW occurring once in each period.

[0468] In some embodiments, the terminal device receives RRC signaling sent by the network side device (base station), and the RRC signaling is used to configure a PPW list on at least one BWP of each of multiple CCs, the PPW list comprising at least one PPW. The multiple CCs are used to simultaneously transmit PRS.

[0469] In some embodiments, on each of the multiple CCs, at least one BWP exists, and the second specified parameter of the PPW corresponding to at least one PPW configuration is the same.

[0470] The second specified parameter includes at least one of a PPW ID (here, an RRC configured PPW ID, which is not the same as the PPW ID in the MAC CE, i.e., the PPW entry), a PPW time domain location (i.e., a PPW period and a starting slot), a length (a number of slots occupied by the PPW), a type (a type when the PRS priority is high), and a priority (a priority of the PRS relative to the PDCCH / PDSCH / CSI-RS).

[0471] i. For example, the BWP #1 of CC #1, the BWP #2 of CC2, and the BWP #3 of CC3 have a PPW configuration corresponding to the same specified PPW parameter, and each BWP can have other PPW configurations. However, the BWP #4 of CC #1, the BWP #5 of CC2, and the BWP #6 of CC3 have different specified parameters of the PPW. In this case, if the three CCs need to be aggregated to transmit PRS, the three BWP (BWP #1, 2, and 3) on the three CCs can be activated for aggregation, because other BWP can not have the same PPW configuration.

[0472] The embodiments of the present disclosure provide a PRS processing window activation method when PRS is transmitted under carrier aggregation, which improves the accuracy of terminal device positioning based on carrier aggregation while reducing the MAC CE signaling overhead.

[0473] In the embodiments of the present disclosure, the method provided by the embodiments of the present disclosure is introduced from the perspective of the network side device and the terminal device, respectively.
