[0049] It should also be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0050] Positioning Technology in Communication Systems

[0051] Referring to Figure 2, the communication system 100 may further include a positioning server 130. The positioning server 130 may be used to determine the location information of the terminal device. The positioning server 130 may be located in the core network. The positioning server 130 may sometimes also be referred to as a positioning device. Taking the NR system as an example, the positioning server 130 may be a location management function (LMF). Taking other communication systems as an example, the positioning server 130 may be a location management unit (LMU), a location management center (LMC) or an evolved serving mobile location center (E-SMLC). It is understandable that the positioning server 130 may also be other network elements, nodes or devices for determining the location information of the terminal device, such as a network element or node for determining the location information of the terminal device in a future communication system. The embodiment of the present application does not specifically limit the name of the positioning server.

[0052] Positioning in the communication system 100 includes uplink positioning and downlink positioning. The embodiments of the present application are mainly introduced with respect to downlink positioning. Some communication systems (such as NR systems) can perform downlink positioning based on a positioning reference signal (PRS). PRS, also known as DL-PRS, is a reference signal used for positioning functions.

[0053] During downlink positioning, the positioning server may first obtain DL-PRS configuration information from at least one base station (or TRP) used for positioning. The positioning server may send the DL-PRS configuration information to the terminal device via ProvideAssistanceData signaling in the LTE Positioning Protocol (LPP). The terminal device may perform positioning measurements on the radio interface based on the received DL-PRS configuration information.

[0054] The DL-PRS configuration information can be used to configure DL-PRS resources. Different base stations can configure their own DL-PRS configuration information and send DL-PRS on the corresponding DL-PRS resources. The terminal device can measure the DL-PRS sent by at least one base station and estimate the relevant information of the positioning measurement. The terminal device 120 can then report the relevant information of the positioning measurement as the DL-PRS measurement result to the positioning server 130. The positioning server 130 can calculate the position of the terminal device 120 based on the positioning measurement related information reported by the terminal device 120, thereby obtaining the position information of the terminal device 120. In some embodiments, the terminal device can also determine the position information by itself based on the DL-PRS measurement result.

[0055] The relevant information of the positioning measurement may include one or more of the following information: time information, distance information, power information, and angle information. For example, the relevant information of the positioning measurement may include one or more of the following information: angle of arrival (AOA), time difference of arrival (TDOA), angle difference of arrival (ADOA), reference signal receive power (RSRP), etc.

[0056] The configuration information of DL-PRS may include time domain configuration information and frequency domain configuration information. The time domain configuration information of DL-PRS is introduced below. The time domain configuration information of DL-PRS may include one or more of the following configuration information: DL-PRS periodicity and resource set slot offset (dl-PRS-Periodicity-and-ResourceSetSlotOffset-r16), DL-PRS resource slot offset (dl-PRS-ResourceSlotOffset), DL-PRS resource repetition factor (Dl-PRS-ResourceRepititionFactor), DL-PRS resource time interval (dl-PRS-ResourceTimeGap), DL-PRS muting mode. The DL-PRS muting mode may include DL-PRS muting option 1 (dl-PRS-MutingOption1) and DL-PRS muting option 2 (dl-PRS-MutingOption2). The above configuration information is introduced below.

[0057] dl-PRS-Periodicity-and-ResourceSetSlotOffset-r16 is used to configure the DL-PRS transmission period and the time slot offset of the DL-PRS resource set, such as the time slot offset of the DL-PRS resource set relative to SFN#0 time slot#0.

[0058] dl-PRS-ResourceSlotOffset is used to configure the time slot offset of the starting time slot of the DL-PRS resource relative to the DL-PRS resource set.

[0059] The Dl-PRS-ResourceRepititionFactor is used to configure the number of repetitions of DL-PRS resources in a DL-PRS resource set instance. This parameter applies to all resources in a DL-PRS resource set.

[0060] dl-PRS-ResourceTimeGap is used to configure the offset in time slots between two repeated instances of a DL-PRS resource corresponding to the same DL-PRS resource ID within a single instance of a DL-PRS resource set. The duration of a DL-PRS resource set containing repeated DL-PRS resources shall not exceed the DL-PRS period.

[0061] This is described below with reference to Figure 3. Assuming that the time slot offset of a PRS resource set is 3 time slots, the PRS resource set includes PRS resource #1 and PRS resource #2, the time slot offset of PRS resource #1 is 1 time slot, the time slot offset of PRS resource #2 is 4 time slots, the time interval for repeated resource transmission is 2 time slots, and the repetition factor of the resources is 2, then the time domain positions of PRS resource #1 and PRS resource #2 can be as shown in Figure 3.

[0062] In the PRS slot configuration shown in Figure 3, since the slot offset of the PRS resource set is 3 slots, the starting slot of the PRS resource set is slot 3. Since PRS resource #1 is offset by 1 slot relative to the PRS resource set, one slot of PRS resource #1 is slot 4. A resource repetition factor of 2 indicates that the PRS resource is repeated twice within a PRS resource set. Furthermore, the interval between resource repetitions is 2 slots, so PRS resource #1 also includes slots 4 and 6. Since the period of a PRS resource set is 10 slots, PRS resource #1 can include slots 4, 6, 14, 16, 24, 26, 34, 36, and so on.

[0063] The determination method of PRS resource #2 is similar to that of PRS resource #1. Since the time slot offset of PRS resource #2 is 4 time slots, the starting time slot of PRS resource #2 is time slot 7. Therefore, PRS resource #2 may include time slot 7, time slot 9, time slot 17, time slot 19, time slot 27, time slot 29, time slot 37, time slot 39, etc.

[0064] The DL-PRS muting pattern defines a bitmap of the time positions at which DL-PRS resources are transmitted or not transmitted. A bit value of 0 indicates that the corresponding resource is muted, and a bit value of 1 indicates that the corresponding resource is not muted.

[0065] Each bit in the DL-PRS muting option 1 bitmap corresponds to a configurable number of consecutive instances of a DL-PRS resource set (in periodic transmission of a DL-PRS resource set). Each bit in the bitmap represents a number of consecutive DL-PRS resource sets. If the bit corresponding to a resource set is 0, it means that all resources in the DL-PRS resource set are muted.

[0066] DL-PRS muting option 1 is described below with reference to FIG4 and FIG5 .

[0067] Assuming that the muting bitmap for option 1 is 1010, PRS resource #1 and PRS resource #2 are muted in PRS resource set 2 and PRS resource set 4, but are not muted in PRS resource set 1 and PRS resource set 3. The time domain positions of PRS resource #1 and PRS resource #2 may be as shown in Figure 4. PRS resource #1 is muted in time slots 14, 16, 34, and 36, and PRS resource #2 is muted in time slots 17, 19, 37, and 39.

[0068] Assuming that the muting bitmap for option 1 is 1100, PRS resource #1 and PRS resource #2 are muted in PRS resource set 3 and PRS resource set 4, but are not muted in PRS resource set 1 and PRS resource set 2. The time domain positions of PRS resource #1 and PRS resource #2 may be as shown in Figure 5. PRS resource #1 is muted in time slots 24, 26, 34, and 36, and PRS resource #2 is muted in time slots 27, 29, 37, and 39.

[0069] Each bit in the bitmap of muting mode option 2 corresponds to a single repetition index for each DL-PRS resource within an instance of a DL-PRS resource set (the length of the bitmap is equal to DL-PRS-ResourceRepetitionFactor). This type of muting operates within a DL-PRS resource set, with each bit in the bitmap representing a resource. If that resource is to be muted, all repetitions of that resource must also be muted.

[0070] Assuming the muting bitmap for option 2 is 0101, the first and third PRS resources in a PRS resource set are muted. As shown in Figure 6, PRS resource #1 is muted in slots 4, 14, 24, and 34, and PRS resource #2 is muted in slots 7, 17, 27, and 37.

[0071] Discontinuous reception (DRX)

[0072] To reduce terminal power consumption, both LTE and NR systems have a DRX mechanism. This allows terminals to enter a discontinuous reception state instead of having to keep their receivers powered on when there is no data to receive, thereby saving power. The DRX mechanism configures a DRX cycle for terminals in a radio resource control (RRC) connected state. A DRX cycle consists of an "on duration" and an "opportunity for DRX." During the on duration, the terminal monitors and receives downlink channels and signals, including the physical downlink control channel (PDCCH). During the inactive duration, the terminal does not receive downlink channels and signals, such as the PDCCH, to reduce power consumption.

[0073] Terminals in the RRC Idle state (IDLE) typically receive paging messages in a manner similar to the DRX mechanism. Within a DRX cycle, there is a paging occasion (PO). Terminals only receive paging messages during the PO and not outside of these periods, saving power. Furthermore, during the PO, terminals can detect the presence of paging messages by detecting the PDCCH, which is scrambled using the Paging Radio Network Temporary Identity (P-RNTI). The paging process is described below with reference to Figure 7.

[0074] Paging process

[0075] In the NR system, the network device can send paging to the terminal in the RRC idle state or the RRC connected state, wherein the paging process can be triggered by the core network or the base station. The paging process can be used to send a paging request to the terminal in the RRC idle state, or the paging process can also be used to notify the terminal of system information updates, or the paging process can also notify the terminal to receive alarm information sent by the earthquake and tsunami warning system (ETWS) and the commercial mobile alert system (CMAS).

[0076] If the paging message is initiated by the core network, the base station will interpret the content of the paging message after receiving it, obtain the tracking area identity (TAI) list of the paged terminal, and then perform air interface paging in the cells belonging to the tracking areas in the list. Typically, to save the overhead of transmitting paging messages, after receiving the paging message sent by the core network, the base station can aggregate the paging messages corresponding to terminals with the same PO into a single paging message, and ultimately transmit it to the relevant terminals via the paging channel.

[0077] The paging message is carried via the physical downlink shared channel (PDSCH). Before receiving the paging message, the terminal must first receive paging parameters via system messages and calculate the frame number and PO of the paging frame (PF) containing the paging message based on its UE_ID. The terminal then listens to the PDCCH scrambled by the P-RNTI within the PO on the PF to receive the paging indication information, and ultimately receives the paging message based on the paging indication information.

[0078] The PF represents the frame number of the system frame in which the paging message should appear, and the PO indicates the time at which the paging message may appear. Figure 7 illustrates the location of the PF and the PO within the DRX cycle. As shown in Figure 7, the PF is located within the DRX cycle (or paging cycle). A PF may include one or more POs, and these multiple POs may correspond to different terminals. However, for a terminal, during the DRX cycle (or paging cycle), it only needs to monitor its own PO.

[0079] As described above, the terminal can calculate the PF and PO based on the UE_ID. In some implementations, the system frame corresponding to the system frame number (SFN) that satisfies the formula (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N) can be used as a PF, and within the PF, the index (index) i_s of the PO corresponding to the terminal can be calculated according to the formula i_s = floor (UE_ID / N) mod Ns. Wherein, T represents the cycle length of the DRX cycle of the terminal; UE_ID is used to identify the terminal; N represents the number of PFs in the DRX cycle; Ns represents the number of POs in a PF. PF_offset represents the frame offset of the PF.

[0080] It should be noted that for a terminal, if the default DRX cycle and the DRX cycle configured for the terminal are different, then the cycle length of the smaller of the two DRX cycles can be selected as the above-mentioned T. That is, T = min(T_UE, T_sib), where T_sib represents the cycle length of the default DRX cycle indicated in the system message, and T_UE represents the cycle length of the DRX cycle configured for the terminal. Of course, if the terminal is not configured with T_UE, the cycle length of the default DRX cycle indicated in the system message can be used as the value of T, that is, T = T_sib. T_UE can be a specific paging cycle configured for the terminal by the terminal's upper layer. T_UE can also be called a UE-level paging cycle.

[0081] It should also be noted that the above UE_ID can be calculated using the formula UE_ID = (5G-S-TMSI mod 1024), where 5G-S-TMSI represents the temporary mobile subscriber identity (TMSI) assigned to the terminal by the communication system. The TMSI can be used to uniquely distinguish different terminals. The TMSI is also used in Msg3 of random access. If the terminal does not have a TMSI, the default UE_ID = 0.

[0082] The above paging parameters can be configured through PCCH-Config as shown below:

[0083]

[0084]

[0085] In addition, NR technology introduces the concept of PDCCH monitoring occasions for paging. The PDCCH monitoring occasion is the time domain location of the control resource set (CORESET), indicated by the paging search space. Combined with the CORESET corresponding to this search space, the CORESET time-frequency resources for receiving PDCCH scrambled by the P-RNTI can be specifically determined. The Paging search space is indicated in the PDCCH-ConfigCommon field of SIB1.

[0086] The PDCCH-ConfigCommon may include a pagingsearchspace field. The pagingsearchspace field may be used to indicate one or more of the following information: search space ID, CORESET ID, period, offset within the period (in slots), number of slots per period, starting symbol in a slot, number of PDCCH candidates per aggregation level configuration, and search space type.

[0087] The search space field allows the terminal to determine a period and offset in time slots, the number of time slots within each period, and the starting symbol position in each time slot, thereby determining all PDCCH monitoring opportunities. Furthermore, the terminal can determine the time-frequency resources of each CORESET based on the information indicated by the corresponding CORESET.

[0088] For a terminal in the RRC idle state, the network device does not know which transmit beam to use to send a paging message to the terminal. To ensure that the terminal can receive the paging message, the network device uses beam scanning to send the paging message. To support multi-beam transmission of paging messages, a PO can be defined as a set of PDCCH monitoring opportunities. Different PDCCH monitoring opportunities correspond to paging indication information sent through different transmit beams. A PF can include one or more POs or the starting time point of a PO.

[0089] When the search space identifier SearchSpaceId of the paging search space is 0, since each synchronization signal / physical broadcast channel block (SSB) index corresponds to a PDCCH monitoring opportunity, and different SSB indices correspond to different beams, multiple PDCCH monitoring opportunities in a PO can be associated with transmit beams corresponding to different SSB indices to support multi-beam transmission of paging messages. Typically, the SSBs required to complete a beam scan constitute an "SSB burst."

[0090] For the case where the search space identifier SearchSpaceId of the paging search space is not 0, a PO includes "S*X" consecutive PDCCH monitoring opportunities, where S is the number of SSBs transmitted in the PO, which is indicated by the "ssb-PositionsInBurst" field in the system information block 1 (SIB1). X represents the number of PDCCH monitoring opportunities corresponding to each SSB, which can be indicated by the "nrofPDCCH-MonitoringOccasionPerSSB-InPO" field of the SIB. If this parameter is not configured, X is 1. For the [x*S+K]th PDCCH monitoring opportunity in a PO, it corresponds to the Kth actually transmitted SSB, where x=0,1,…,X-1,K=1,2,…,S. For example, S=8, X=2, then one PO includes 16 PDCCH monitoring opportunities, and the SSB indexes corresponding to the 16 PDCCH monitoring opportunities in chronological order are "0123456701234567", where the index numbers of the first 8 SSBs are 0-7.

[0091] In LTE, a PO is a subframe. After the terminal calculates the PF and PO, it can determine the subframe for paging detection. In NR, the search space is no longer a fixed time domain position in each frame, that is, the period is no longer in frames but in slots, so the PDCCH monitoring occasions need to be determined through the above-mentioned search space field. And because each PO must correspond to all SSBs, each PO must contain S PDCCH monitoring occasions, each PDCCH monitoring occasion corresponds to an SSB, and S is the number of SSBs actually sent within an SSB set period. Therefore, after determining the PDCCH monitoring occasion, PF, and PO, the PDCCH monitoring occasions must be matched with each PO to determine the PDCCH monitoring occasions for paging of a certain UE.

[0092] In NR, a PF is still a system frame, but a PO is no longer contained only in the PF, that is, a PF no longer contains several POs, but corresponds to several POs, because all PDCCH monitoring occasions between two PFs are PDCCH monitoring occasions that constitute the PO.

[0093] As can be seen from the above description, the DL-PRS configuration information is configured by the base station, while the DRX configuration information is basically configured by the base station, such as the base station can broadcast the DRX configuration information to the terminal device. The DRX configuration information can be used by the terminal device to determine the DRX activation period. For the paging detection scenario of the terminal device, the DRX configuration information may include the paging cycle, the terminal device can configure T_UE by itself, and other configuration information can be configured for the terminal device by the base station. In the paging detection scenario, the DRX configuration information can be used by the terminal device to determine the timing of the paging detection, such as the PF time domain position and / or the PO time domain position.

[0094] Currently, DRX configuration information and DL-PRS configuration information are configured independently, which can cause the DL-PRS time domain position to be inconsistent with the DRX activation period. Terminals may need to wake up during DRX inactivity periods to measure the DL-PRS, resulting in additional power consumption. For low-power, high-precision positioning scenarios, reducing terminal device power consumption is crucial, and this inconsistency in time domain position undoubtedly hinders power consumption.

[0095] Based on this, embodiments of the present application provide a resource configuration method and apparatus. By aligning the time domain position of the DL-PRS with the DRX activation period, this method prevents terminal devices from waking up to measure the DL-PRS during the DRX inactivity period, thereby reducing terminal device power consumption. The resource configuration method of an embodiment of the present application is described below with reference to FIG8 . The method shown in FIG8 includes step S810.

[0096] In step S810, the first device adjusts the DL-PRS configuration information and / or the DRX configuration information according to the DL-PRS configuration information and the DRX configuration information, so that the time domain position of the DL-PRS is consistent with the DRX activation period.

[0097] The embodiments of the present application do not specifically limit the first device. The first device may be, for example, a base station, a positioning server, or another core network element. The positioning server may be, for example, a LMF. The other core network elements may include core network elements other than the positioning server. For example, the other core network element may be an access and mobility management function (AMF).

[0098] The DL-PRS configuration information may be obtained from at least one base station (or TRP) used for positioning. The DL-PRS configuration information in the embodiment of the present application may include DL-PRS configuration information corresponding to at least one base station. Different base stations can set their own DL-PRS configuration information.

[0099] The DL-PRS configuration information may include configuration information for the time domain location of the DL-PRS. For example, the DL-PRS configuration information may include one or more of the following parameters: a DL-PRS transmission period, a time slot offset of a DL-PRS resource set, a time slot offset of a DL-PRS resource, a repetition factor of a DL-PRS resource, a time interval for repeated transmission of a DL-PRS resource, and a DL-PRS muting mode. The configuration information for the time domain location of the DL-PRS may be used to determine the time domain resource location of the DL-PRS.

[0100] The DRX configuration information may be configured by a base station and / or a terminal device. The DRX configuration information may include DRX time domain configuration information, for example, the DRX configuration information may include a DRX cycle. The DRX configuration information may be used to determine a DRX activation period.

[0101] The first device may adjust the DRX configuration information and / or the DL-PRS configuration information based on the DRX configuration information and the DL-PRS configuration information so that the time domain position of the DL-PRS is consistent with the DRX activation period. Keeping the time domain position of the DL-PRS consistent with the DRX activation period can be understood as that the time domain position of the DL-PRS falls within the DRX activation period, or in other words, the DRX activation period includes the time domain position of the DL-PRS. By keeping the time domain position of the DL-PRS consistent with the DRX activation period, the terminal device can measure the DL-PRS during the DRX activation period without waking up outside the DRX activation period to measure the DL-PRS, thereby reducing the power consumption of the terminal device.

[0102] As can be seen from the foregoing description, the paging cycle is similar to the DRX cycle, and the terminal device can perform paging detection during the activation period of DRX, and can remain in a sleep state without performing paging detection during the inactive period of DRX. In order to further reduce the power consumption of the terminal device, the terminal device may not need to perform paging detection throughout the entire DRX activation period, but only perform paging detection at the time domain position of its corresponding PF or PO, and continue to remain in a sleep state at other times. Based on this, the embodiment of the present application can adjust the configuration information of DL-PRS and / or the configuration information of DRX, so that the time domain position of DL-PRS is consistent with the time domain position of PF and / or the time domain position of PO. In other words, the terminal device only needs to wake up at the time domain position of PF or the time domain position of PO to perform DL-PRS measurement, and does not need to wake up at other times to perform DL-PRS measurement, thereby further reducing the power consumption of the terminal device.

[0103] The time domain position of the DL-PRS is consistent with the time domain position of the PF, which can be understood as the time domain position of the DL-PRS falls on the time domain position of the PF, or in other words, the time domain position of the PF includes the time domain position of the DL-PRS.

[0104] The time domain position of the DL-PRS is consistent with the time domain position of the PO, which can be understood as the time domain position of the DL-PRS falls on the time domain position of the PF, or in other words, the time domain position of the PO includes the time domain position of the DL-PRS.

[0105] As mentioned above, the time domain position of PO can be a subframe position or a PDCCH monitoring time, and the embodiments of the present application do not make specific limitations on this.

[0106] In some embodiments, the DRX configuration information may include one or more of the following parameters: paging cycle, the number of PFs in the DRX cycle, the frame offset of the PF, the number of POs in a PF, the first PDCCH monitoring timing of the PO, and the paging search space. The above-mentioned DRX configuration information can be used to determine the time domain position of the PF and / or the time domain position of the PO corresponding to the terminal device. In some embodiments, the DRX configuration information may also be referred to as paging cycle configuration information. The method for determining the time domain position of the PF and / or the time domain position of the PO can be found in the previous description and will not be repeated here for the sake of brevity.

[0107] The paging cycle may include a default paging cycle and / or a paging cycle of the terminal device. For the convenience of description, the default paging cycle will be referred to as the first paging cycle, and the paging cycle of the terminal device will be referred to as the second paging cycle. The first paging cycle may be configured by the base station to the terminal device, and the second paging cycle may be configured by the upper layer (such as the application layer) of the terminal device for the terminal device. The first paging cycle is the T_sib described above, and the second paging cycle is the T_UE described above. The terminal device may select a smaller paging cycle from the first paging cycle and the second paging cycle as the paging cycle actually used.

[0108] That is to say, the DRX configuration information in the embodiment of the present application may include relevant information of the DRX configured by the base station for the terminal device and the second paging cycle of the terminal device. Among them, the DRX related information may include the first paging cycle. The base station may configure relevant information for the terminal device, including one or more of the following: a default paging cycle, the number of PFs in the DRX cycle, the frame offset of the PF, the number of POs in a PF, the first PDCCH monitoring opportunity of the PO, and the paging search space. In some embodiments, the relevant information of the DRX configured by the base station for the terminal device may also be referred to as DRX configuration information.

[0109] The embodiments of the present application do not specifically limit the manner in which the first device adjusts the configuration information. The first device may determine the DRX activation period based on the DRX configuration information, and determine the DL-PRS time domain location based on the DL-PRS configuration information. Furthermore, the first device may determine an adjustment strategy based on the DRX activation period and the DL-PRS time domain location.

[0110] As an example, the first device may adjust the DL-PRS configuration information based on the DL-PRS configuration information and the DRX configuration information, so that the time domain position of the DL-PRS after adjustment is consistent with the activation period of the DRX.

[0111] As another example, the first device may adjust the DRX configuration information based on the DL-PRS configuration information and the DRX configuration information, so that the DRX activation period after the adjustment is consistent with the time domain position of the DL-PRS.

[0112] As another example, the first device may adjust both the DRX configuration information and the DL-PRS based on the DL-PRS configuration information and the DRX configuration information, so that the adjusted DRX activation period is consistent with the time domain position of the adjusted DL-PRS.

[0113] The first device may flexibly select the above adjustment method based on actual conditions. For example, if the adjustable range of the DL-PRS configuration information is relatively small and the adjusted DL-PRS time domain position cannot be made consistent with the DRX activation period, the first device may choose to adjust the DRX configuration information, or adjust both the DRX configuration information and the DL-PRS configuration information.

[0114] For another example, if the adjustable range of the DRX configuration information is relatively small and the adjusted DRX activation period cannot be kept consistent with the time domain position of the DL-PRS, the first device may choose to adjust the DL-PRS configuration information, or adjust both the DRX configuration information and the DL-PRS configuration information.

[0115] In some embodiments, the first device may directly determine the adjusted configuration information, or may only determine the adjusted configuration information. The adjusted information may be understood as an adjustment suggestion. For example, if the first device has permission to adjust the configuration information, the first device may directly determine the adjusted configuration information. If the first device does not have permission to adjust the configuration information, the first device may only determine the adjusted configuration information.

[0116] In some embodiments, the first device may obtain DL-PRS configuration information and determine adjustment information for the DL-PRS configuration information. Furthermore, the first device may transmit the adjustment information for the DL-PRS configuration information. In some embodiments, the first device may obtain DRX configuration information and determine adjustment information for the DRX configuration information. Furthermore, the first device may transmit the adjustment information for the DRX configuration information. In some embodiments, the first device may obtain DRX configuration information and determine adjusted DRX configuration information. Furthermore, the first device may transmit the adjusted DRX configuration information.

[0117] The following describes an adjustment method for the first device in the case where the first device is a different device.

[0118] As an example, if the first device is a base station, since the base station does not have the authority to adjust the DL-PRS configuration information, the base station may determine the adjustment information of the DL-PRS configuration information. The base station may send the adjustment information of the DL-PRS configuration information. In addition, since the base station has the authority to adjust the DRX configuration information, the base station may directly determine the adjusted DRX configuration information. The base station may send the adjusted DRX configuration information.

[0119] If the first device is a base station, the base station can obtain DL-PRS configuration information from the positioning server. That is, the positioning server can send the DL-PRS configuration information, and the base station can receive the DL-PRS configuration information. In addition, the base station can obtain the second paging cycle from the terminal device. That is, the terminal device can send the second paging cycle, and the base station can receive the second paging cycle.

[0120] As another example, if the first device is a positioning server, then because the positioning server does not have permission to adjust the DRX configuration information, the positioning server may determine the adjustment information for the DRX configuration information. The positioning server may send the adjustment information for the DRX configuration information, or the positioning server may negotiate with the base station used for positioning about the adjusted DRX configuration information based on the adjustment information for the DRX configuration information. Because the DL-PRS configuration information requires the participation of the base station used for positioning, the positioning server may negotiate with the base station used for positioning to determine the adjusted DL-PRS configuration information.

[0121] If the first device is a positioning server, the positioning server may obtain DRX configuration information from the base station and / or the terminal device. For example, where the DRX configuration information includes DRX-related information configured by the base station for the terminal device and a second paging cycle, the base station may send the DRX-related information, and the positioning server may receive the DRX-related information; the terminal device may send the second paging cycle, and the positioning server may receive the second paging cycle.

[0122] As another example, if the first device is another core network element, then since the first device has neither DRX configuration information adjustment authority nor DL-PRS configuration information adjustment authority, the first device may determine the adjustment information of the DRX configuration information and the adjustment information of the DL-PRS configuration information. The first device may send the adjustment information of the DRX configuration information and the adjustment information of the DL-PRS configuration information. The other core network element may refer to a core network element other than the LMF.

[0123] If the first device is another core network element, the first device can obtain DRX configuration information from the base station and / or the terminal device. Taking the example of DRX configuration information including DRX-related information and the second paging cycle configured by the base station for the terminal device, the base station can send DRX-related information, and the first device can receive DRX-related information; the terminal device can send the second paging cycle, and the first device can receive the second paging cycle. In addition, the first device can receive DL-PRS configuration information from the positioning server. For example, the positioning server can send DL-PRS configuration information, and the first device can receive the DL-PRS configuration information.

[0124] It can be understood that in the above process, the DL-PRS configuration information sent by the positioning server can be used to adjust the DL-PRS configuration information and / or DRX configuration information so that the time domain position of the DL-PRS is consistent with the DRX activation period; the second paging cycle sent by the terminal device can be used to adjust the DL-PRS configuration information and / or DRX configuration information so that the time domain position of the DL-PRS is consistent with the DRX activation period; the DRX-related information (or DRX configuration information) sent by the base station can be used to adjust the DL-PRS configuration information and / or DRX configuration information so that the time domain position of the DL-PRS is consistent with the DRX activation period.

[0125] For a terminal device, the terminal device may receive adjusted DRX configuration information or receive adjustment information of the DRX configuration information. If the terminal device receives adjusted DRX configuration information, the terminal device may perform paging detection at a corresponding resource location based on the adjusted DRX configuration information. If the terminal device receives adjustment information of the DRX configuration information, the terminal device may adjust the second paging cycle and determine the resource location for the paging detection based on the second paging cycle.

[0126] In some embodiments, the adjustment information of the DRX configuration information includes adjustment information for one or more of the following parameters: a paging cycle, a number of PFs within a DRX cycle, a frame offset of a PF, a number of POs within a PF, a first PDCCH monitoring opportunity of a PO, and a paging search space. In some embodiments, the adjustment information of the DRX configuration information may include an adjustable range of a DRX activation period.

[0127] In some embodiments, the adjustment information of the DL-PRS configuration information includes adjustment information for one or more of the following parameters: a DL-PRS transmission period, a time slot offset of a DL-PRS resource set, a time slot offset of a DL-PRS resource, a repetition factor of a DL-PRS resource, a time interval for repeated transmission of a DL-PRS resource, and a DL-PRS muting mode. In some embodiments, the adjustment information of the DL-PRS configuration information may include an adjustable range of a DL-PRS time domain position.

[0128] The following introduces the resource configuration process when the first device is a different device. Figure 8 shows the resource configuration process when the first device is a base station, and Figure 9 shows the resource configuration process when the first device is other core network elements. It should be noted that Figures 8 and 9 are an introduction to this application using the paging scenario as an example, but this application is not limited to this. For example, for a normal DRX scenario, the first device may not need to obtain the second paging cycle from the terminal device.

[0129] Example 1: The first device is a base station

[0130] Referring to FIG. 9 , the method shown in FIG. 9 includes steps S902 to S918 .

[0131] In step S902, the positioning server obtains DL-PRS configuration information from at least one base station used for positioning.

[0132] In step S904, the positioning server sends DL-PRS configuration information to the base station. The base station may be a serving base station of the terminal device. In some embodiments, the positioning server may send the DL-PRS configuration information to the base station via the NR positioning protocol (NR positioning protocol, NRPPa).

[0133] In step S906, if the DRX configuration information is used for paging detection of the terminal device, the base station may further send a first request message to the terminal device to request a second paging cycle. The first request message may be carried in RRC signaling.

[0134] In step S908, after receiving the first request message, the terminal device may send a second paging cycle to the base station.

[0135] In step S910, the base station may determine adjusted DRX configuration information and / or adjustment information of DL-PRS configuration information based on the DRX configuration information and DL-PRS configuration information. The DRX configuration information may include DRX-related information configured by the base station for the terminal device and the second paging cycle.

[0136] Since most parameters in the DRX configuration information are configured by the base station, the base station can directly determine the adjusted DRX configuration information. However, the base station does not have the authority to adjust the DL-PRS configuration information, so the base station can only determine the adjustment information of the DL-PRS configuration information.

[0137] In step S912, the base station sends the adjusted DRX configuration information to the terminal device. There are various ways to send the adjusted DRX configuration information, which are not specifically limited in this embodiment of the present application. For example, the base station may send the adjusted DRX configuration information to the terminal device via one or more of RRC signaling, MAC CE, and broadcast.

[0138] After receiving the adjusted DRX configuration information, the terminal device can perform paging detection according to the adjusted DRX configuration information. For example, after entering the RRC-IDLE state or the RRC-INACTIVE state, the terminal device can determine the timing for performing paging detection (such as the time domain position of PO or the time domain position of PF) according to the adjusted DRX configuration information, and perform paging detection at the corresponding detection timing.

[0139] In step S914, the base station sends adjustment information for the DL-PRS configuration information to the positioning server. Since the DL-PRS configuration information is configured by the positioning server and / or the base station, and the base station does not have the authority to adjust the DL-PRS, the base station may send the adjustment information for the DL-PRS configuration information to the positioning server. The above adjustment information can be understood as an adjustment suggestion. The adjustment information may include an adjustable interval for the time domain position of the DL-PRS. In some embodiments, the base station may send a message to the positioning server to ensure that the DRX activation period is consistent with the time domain position of the DL-PRS.

[0140] In some embodiments, the base station may send the DRX activation period to the positioning server, so that the positioning server adjusts the DL-PRS configuration information by itself.

[0141] In step S916, after receiving the adjustment information sent by the base station, the positioning server may negotiate with each base station used for positioning to determine the adjusted DL-PRS configuration information.

[0142] In step S918, after the negotiation is completed, the positioning server may send the adjusted DL-PRS configuration information to the terminal device and / or each base station used for positioning. In some embodiments, the positioning server may send the adjusted DL-PRS configuration information to the terminal device via LPP ProvideAssistanceData signaling.

[0143] After receiving the adjusted DL-PRS configuration information, the base station may send the DL-PRS at the corresponding resource location. After receiving the adjusted DL-PRS configuration information, the terminal device may measure the DL-PRS based on the adjusted DL-PRS configuration information.

[0144] Example 2: The first device is another core network element

[0145] Referring to FIG. 10 , the method shown in FIG. 10 includes steps S1002 to S1026 .

[0146] In step S1002, the positioning server obtains DL-PRS configuration information from at least one base station used for positioning.

[0147] In step S1004, the positioning server may send a first request message to the first device, where the first request message is used to request that the DRX activation period be consistent with the DL-PRS time domain position. In addition, the positioning server may also send DL-PRS configuration information to the first device.

[0148] In step S1006, after receiving the first request message sent by the positioning server, the first device may send a second request message to the base station.

[0149] In step S1008, after receiving the first request message sent by the positioning server, the first device may send a third request message to the terminal device.

[0150] The second request message and the third request message are used to request DRX configuration information. For example, the second request message is used to request the base station to configure DRX related information for the terminal device, and the third request message is used to request a second paging cycle.

[0151] In step S1010, after receiving the second request message, the base station may send DRX related information to the first device. For example, the base station may send DRX related information to the first device via an NG interface.

[0152] In step S1012, after receiving the third request message, the terminal device may send the second paging cycle to the first device. For example, the terminal device may send the second paging cycle to the first device via the air interface NAS.

[0153] In step S1014, the first device determines adjustment information for the DRX configuration information and / or adjustment information for the DL-PRS configuration information based on the DRX configuration information and the DL-PRS configuration information. Since the first device does not have permission to adjust the DRX configuration information and the DL-PRS configuration information, the first device may only determine the adjustment information for the DRX configuration information and the adjustment information for the DL-PRS configuration information, and send the adjustment information to the respective corresponding devices.

[0154] In step S1016, the first device sends adjustment information of DL-PRS configuration information to the positioning server.

[0155] In step S1018, the first device sends adjustment information of the DRX configuration information to the base station and / or the terminal device.

[0156] In step S1020, the base station may determine adjusted DRX configuration information based on the adjustment information of the DRX configuration information.

[0157] In step S1022, the base station sends the adjusted DRX configuration information to the terminal device.

[0158] After receiving the adjusted DRX configuration information, the terminal device can perform paging detection according to the adjusted DRX configuration information. For example, after entering the RRC-IDLE state or the RRC-INACTIVE state, the terminal device can determine the timing for performing paging detection (such as the time domain position of PO or the time domain position of PF) according to the adjusted DRX configuration information, and perform paging detection at the corresponding detection timing.

[0159] In step S1024, after receiving the adjustment information sent by the base station, the positioning server may negotiate with each base station used for positioning to determine the adjusted DL-PRS configuration information.

[0160] In step S1026, after the negotiation is completed, the positioning server may send the adjusted DL-PRS configuration information to the terminal device and / or each base station used for positioning. In some embodiments, the positioning server may send the adjusted DL-PRS configuration information to the terminal device via LPP ProvideAssistanceData signaling.

[0161] After receiving the adjusted DL-PRS configuration information, the base station used for positioning can send the DL-PRS at the corresponding resource location. After receiving the adjusted DL-PRS configuration information, the terminal device can measure the DL-PRS at the corresponding resource location based on the adjusted DL-PRS configuration information.
