Technical Field
[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for transmitting and receiving capability information. Background Technology
[0002] The Positioning Reference Signal (PRS) was introduced in Release 16 (R16) of the 3rd Generation Partnership Project (3GPP), which can be used for positioning measurements. In New Radio (NR) positioning measurements, the UE supports measuring the PRS on a single carrier. To improve positioning accuracy, multi-carrier-based positioning measurements have been introduced, requiring the resolution of potential conflicts between the PRS and other downlink signals during the positioning measurement process. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0081] like Figure 1As shown, the method for transmitting and receiving capability information provided in this disclosure can be applied to a wireless communication system 100. This wireless communication system 100 is applicable to both low-frequency and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems, etc.
[0082] Combination Figure 1 As shown, the wireless communication system may include: user equipment 101, network device 102, and Location Management Function (LMF) 103. During positioning measurement, LMF 103 and user equipment 101 can communicate based on the LTE Positioning Protocol (LPP). During this communication, network device 102 can act as a transparent node, forwarding messages between the two. For example, network device 102 forwards messages sent by user equipment 101 to LMF 103; or, network device 102 forwards messages sent by LMF 103 to user equipment 101. LMF 103 and network device 102 can communicate based on NR Positioning Protocol A (NRPPA). In this wireless communication system, positioning service functions such as LMF 103 are used specifically for positioning-related configuration and calculation to maintain the privacy of positioning-related data and improve its security and reliability.
[0083] User equipment 101 can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent, or terminal device, etc. User equipment 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices of one or more communication systems and receive network services provided by the network devices. Network device 102 includes, but is not limited to, the illustrated base station. For example, user equipment 101 can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a future 5G network, or terminal device in a future evolved PLMN network, etc. User equipment 101 is configured to support carrier aggregation and can connect to multiple carrier units of network device 102, including a primary carrier unit and one or more secondary carrier units.
[0084] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network device 102 can be a wearable device or an in-vehicle device. Network device 102 can also be a communication chip with a communication module. For example, network equipment 102 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home nodeB, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.
[0085] LMF103 is a unit in the 5G core network that acts as a positioning server, providing user equipment 101 with configuration or auxiliary data related to positioning and measurement. For example, LMF103 can provide user equipment 101 with information related to the signal to be measured. LMF103 can also configure information related to the signal to be transmitted for different network nodes, such as network device 102. During positioning and measurement, LMF103 can receive measurement results from user equipment 101 and network device 102, and combine the measurement results to determine the location information of user equipment 101.
[0086] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 2 , Figure 2 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 2 As shown, the method includes steps S201 to S203, specifically:
[0087] In step S201, user equipment 101 sends capability information to network equipment 102. The capability information includes the user equipment 101's ability to receive positioning reference signals (PRS) on different carriers at the same time domain location and to set downlink signals.
[0088] The embodiments disclosed herein can be applied to positioning measurement scenarios in multi-carrier systems. For example, positioning measurement in carrier aggregation (CA) or dual connectivity (DC) systems.
[0089] In some possible implementations, in a positioning measurement scenario, the capability information of user equipment 101 can also be sent to LMF 103 via network device 102.
[0090] In this embodiment, LMF103 can configure PRS resources on multiple carriers supported by user equipment 101 based on the capability information of user equipment 101.
[0091] In one example, LMF103 determines first configuration information and second configuration information based on the capability information of user equipment 101. LMF103 sends the first configuration information to user equipment 101 through network device 102 to indicate the time-domain location for receiving PRS on multiple carriers. LMF103 sends the second configuration information to network device 102 to indicate the time-domain location for transmitting PRS on multiple carriers.
[0092] In one example, LMF103 sends two types of configuration information to network device 102 via a ProvideAssistanceData message. When forwarding the first configuration information, network device 102 simply forwards the message without processing it.
[0093] In some possible implementations, user equipment 101 may send capability information to network device 102 via IE MeasAndMobParametersMRDC signaling or IE MeasAndMobParameters signaling.
[0094] In some possible implementations, for a multi-carrier system with multiple carriers, such as two carriers, three carriers, or more carriers, the PRS and the set downlink signal may be transmitted on different carriers respectively. The capability information of user equipment 101 is used to characterize the ability of user equipment 101 to receive signals on different carriers in this scenario.
[0095] In one example, the different carriers include a first carrier and a second carrier, with the PRS transmitted on the first carrier and the setup downlink signal transmitted on the second carrier. Capability information includes the ability of user equipment 101 to receive both the PRS on the first carrier and the setup downlink signal on the second carrier at the same time-domain location.
[0096] In some possible implementations, the setting downlink signal may include at least one of the following:
[0097] Type 1 downlink signal used for mobility measurement;
[0098] The second type of downlink signal is used to carry data.
[0099] In one example, the first type of downlink signal can be one of the following: a Synchronization Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS).
[0100] In one example, the second type of downlink signal can be one of the following: Physical Downlink Shared Channel (PDSCH) or Physical Downlink Control Channel (PDCCH).
[0101] In some possible implementations, the capability information includes whether the user equipment supports at least one of the following capabilities: a first capability, a second capability, and a third capability.
[0102] Among them, the PRS is the same as the sub-carrier spacing (SCS) of the downlink signal, and the capability information is the PRS on different carriers at the same time domain location and the first capability of the downlink signal.
[0103] The PRS differs from the SCS of the first type of downlink signal. The capability information is the second capability of receiving PRS and first type downlink signals on different carriers at the same time domain location.
[0104] The PRS differs from the SCS of the second type of downlink signal. The capability information is the third capability of receiving PRS and second type of downlink signals on different carriers at the same time domain location.
[0105] In this embodiment, when the user equipment 101 does not support the first capability, it generally does not support the second and third capabilities either.
[0106] In this embodiment, when the user equipment 101 supports the second or third capability, it can generally support the first capability.
[0107] In this implementation, different carriers may correspond to two different carriers, or three different carriers, or more different carriers, with different signals transmitted on each carrier.
[0108] In step S202, network device 102 receives capability information.
[0109] In some possible implementations, the capability information may indicate whether the user equipment 101 supports at least one of the following capabilities: a first capability, a second capability, and a third capability. The specific capabilities corresponding to the first, second, and third capabilities are described above and will not be repeated here.
[0110] In step S203, network device 102 performs scheduling based on capability information.
[0111] In some possible implementations, in a positioning measurement scenario, network device 102 combines the capability information of user equipment 101 to adaptively schedule, such as performing measurement configuration or adjusting the way signals are transmitted on different carriers.
[0112] For example, when user equipment 101 does not support the first capability, that is, user equipment 101 cannot simultaneously receive PRS and setting downlink signals on different carriers, network equipment 102 can be configured with a measurement gap (MG) suitable for transmitting PRS on multiple carriers.
[0113] For example, when user equipment 101 supports the second capability, network equipment 102 can transmit PRS and Type I downlink signals on different carriers respectively.
[0114] For example, when user equipment 101 supports the third capability, network equipment 102 can transmit PRS and Type II downlink signals on different carriers respectively.
[0115] In this embodiment of the disclosure, user equipment 101 sends capability information to network device 102 to report its ability to receive PRS and set downlink signals on multiple carriers. Thus, network device 102 can know the signal reception capability of user equipment 101 in a multi-carrier positioning and measurement scenario, and can then perform reasonable scheduling based on the capabilities of user equipment 101.
[0116] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 3 , Figure 3 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 3As shown, the method includes steps S301 to S306, specifically:
[0117] In step S301, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 does not support a first capability. The first capability corresponds to the ability to receive PRS and the set downlink signal on different carriers at the same time domain location, where the PRS and the set downlink signal have the same subcarrier spacing (SCS).
[0118] In some possible implementations, if the user equipment 101 does not support the first capability, it generally does not support the second and third capabilities either.
[0119] In some possible implementations, different carriers may correspond to two different carriers, or three different carriers, or more different carriers.
[0120] In some possible implementations, the downlink signal is configured to include a first type of downlink signal and / or a second type of downlink signal.
[0121] In step S302, network device 102 receives capability information.
[0122] In step S303, network device 102 sends measurement configuration information to user equipment 101, the measurement configuration information including the measurement gap for measuring PRS.
[0123] In some possible implementations, after receiving capability information, network device 102 may determine measurement configuration information if it learns that user equipment 101 does not support the first capability.
[0124] In some possible implementations, before determining the measurement configuration information, user equipment 101 may send auxiliary information to network device 102, which may include the measurement gap parameters that user equipment 101 expects for the capability.
[0125] In one example, auxiliary information may include carrier frequency information, the initial offset value of the measurement gap, etc. The carriers corresponding to the frequency(s) in the auxiliary information are one or more of multiple carriers.
[0126] In one example, the auxiliary information may also include the measurement configurations related to the first configuration information.
[0127] In this embodiment, user equipment 101 can send auxiliary information to network device 102 via LocationMeasurementInfo message.
[0128] In this embodiment, upon obtaining auxiliary information, network device 102 can determine on which carriers the capability user equipment 101 supports for PRS measurement, and when the capability user equipment 101 performs positioning measurements. This allows for adaptive configuration of the time-frequency resources of the measurement intervals, for example, configuring the frequency domain position (carrier) and time domain position (offset and period, etc.) of the measurement intervals, i.e., determining the measurement configuration information.
[0129] In some possible implementations, network device 102 may send measurement configuration information to user equipment 101 via Radio Resource Control (RRC) signaling.
[0130] In step S304, user equipment 101 receives measurement configuration information.
[0131] In some possible implementations, the user equipment 101 can know the time-frequency position of the measurement gap based on the measurement configuration information, that is, it can know the time-frequency position of the PRS being monitored.
[0132] In step S305, network device 102 sends PRS during the measurement interval.
[0133] In some possible implementations, network device 102, in conjunction with measurement configuration, transmits PRS at a reasonable time-domain location on at least one of the multiple carriers.
[0134] In some possible implementations, during the time domain interval corresponding to the measurement gap, network device 102 transmits PRS on at least one carrier of the multi-carrier system and does not perform scheduling on the other carriers of the multi-carrier system.
[0135] In step S306, user equipment 101 receives and measures PRS within the measurement gap.
[0136] In some possible implementations, user equipment 101 receives and measures the PRS sent by network device 102 during the measurement interval according to measurement configuration information.
[0137] In some possible implementations, there may be multiple network devices 102 that transmit PRS, or network devices 102 may be configured to transmit PRS on multiple carriers.
[0138] In some possible implementations, user equipment 101 measures the received PRS and obtains the measurement result.
[0139] In one example, the measurements include one or more of the following: propagation delay, time difference of arrival (TDOA), angle of arrival (AOD), etc.
[0140] In some possible implementations, user equipment 101 sends measurement results to network device 102, and network device 102 forwards the measurement results to LMF 103. LMF 103 performs location-related calculations based on the measurement results, such as determining the location information of user equipment 101.
[0141] In one example, location information may include the geographic location of user device 101, such as location coordinates, which may represent the longitude, latitude, and altitude of user device 101. Alternatively, location information may include the city or region where user device 101 is located. Alternatively, location information may include relative coordinates of user device 101, such as relative coordinates relative to a known location point.
[0142] In a specific example:
[0143] LMF103 configures PRS resources for user equipment 101 on CC1 and CC2. Network device 102, combining the configuration of LMF103 and auxiliary information from user equipment 101, can configure measurement gaps applied to CC1 and CC2. Network device 102 transmits PRS in the time domain intervals corresponding to the measurement gaps on CC1 and CC2, respectively. User equipment 101 receives the PRS on CC1 and CC2 during the measurement gaps and obtains the measurement results of the PRS.
[0144] In this example, network device 102 does not perform downlink signal scheduling during measurement intervals on other supported carriers such as CC3 and CC4, such as not transmitting downlink reference signals or PDCCH.
[0145] In this embodiment of the disclosure, when the PRS and the SCS between the set downlink signals are the same, and the user equipment 101 does not support the first capability, the network device 102 can configure resources for the user equipment 101 with this capability to measure the PRS under multi-carrier conditions, so that the user equipment 101 can perform positioning measurements under multi-carrier conditions and improve positioning accuracy. During this positioning measurement process, the network device 102 does not perform scheduling of the set downlink signals.
[0146] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 4 , Figure 4 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 4 As shown, the method includes steps S401 to S404, specifically:
[0147] In step S401, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 supports a first capability. The first capability corresponds to the ability to receive PRS and the set downlink signal on different carriers at the same time domain location, where the PRS and the set downlink signal have the same subcarrier spacing (SCS).
[0148] In some possible implementations, in addition to supporting the first capability, user equipment 101 may also support the second and / or third capabilities.
[0149] In step S402, network device 102 receives capability information.
[0150] In step S403, network device 102 transmits PRS on at least one carrier of the multi-carrier at the same time domain location, and transmits a set downlink signal on the remaining carriers of the multi-carrier at the same time domain location.
[0151] In some possible implementations, the downlink signal is configured to include a first type of downlink signal and / or a second type of downlink signal.
[0152] In some possible implementations, network device 102 may transmit PRS on at least one carrier according to second configuration information. Among the multiple carriers supported by network device 102, the second configuration information may configure time-domain resources for transmitting PRS on some carriers. In this case, network device 102 can also utilize the remaining carriers to schedule downlink signals.
[0153] In one example, network device 102 may also indicate the time-frequency resources for setting downlink signals.
[0154] In step S404, user equipment 101 receives PRS on at least one carrier of multiple carriers at the same time domain location, and receives set downlink signals on the remaining carriers of multiple carriers at the same time domain location.
[0155] In a specific example:
[0156] LMF103 configures PRS resources for user equipment 101 on CC1 and CC2.
[0157] Network device 102 sends PRS on CC1 and CC2 respectively, based on the second configuration information.
[0158] When network device 102 and user equipment 101 support more carriers, network device 102 can also transmit downlink reference signals on CC3 and PDCCH on CC4 at the same time domain location. The SCS of the PRS, downlink reference signals, and PDCCH are the same.
[0159] In this example, user equipment 101 supporting the first capability receives PRS on CC1 and CC2 at the same time domain location, and receives downlink reference signal on CC3 and PDCCH on CC4.
[0160] In this embodiment of the disclosure, when the SCS between signals is the same, and the user equipment 101 supports the first capability, the network device 102 can combine the user equipment 101 with this capability to send PRS and set downlink signals on different carriers, so that in the scenario where the user equipment 101 performs positioning measurement under multiple carriers, other downlink scheduling can be performed.
[0161] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 5 , Figure 5 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 5 As shown, the method includes steps S501 to S504, specifically:
[0162] In step S501, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 supports the first capability and the second capability, but does not support the third capability.
[0163] The first capability corresponds to the ability to receive PRS and the set downlink signal on different carriers at the same time domain location, with the PRS and the set downlink signal having the same subcarrier spacing (SCS).
[0164] The second capability corresponds to the ability to receive PRS and Type I downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type I downlink signal are different.
[0165] The third capability corresponds to the capability to receive PRS and Type II downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type II downlink signal are different.
[0166] In step S502, network device 102 receives capability information.
[0167] In step S503, network device 102 transmits PRS on the first carrier in the multi-carrier at the same time domain location, and transmits first type downlink signal on the second carrier in the multi-carrier at the same time domain location, but does not transmit second type downlink signal.
[0168] In this context, "first" or "second" in "first carrier" or "second carrier" is used only to distinguish different carriers, not to limit the number of carriers. For example, "first carrier" or "second carrier" may include at least one.
[0169] In some possible implementations, network device 102 may also indicate time-frequency resources for the first type of downlink signal.
[0170] In step S504, user equipment 101 receives the PRS on the first carrier and the first type of downlink signal on the second carrier in the multi-carrier at the same time domain location, but does not listen to the second type of downlink signal.
[0171] In a specific example:
[0172] Network device 102 sends a PRS on CC1 in conjunction with the second configuration information, and at the same time sends a downlink reference signal such as SSB on CC2.
[0173] User equipment 101, combining the first configuration information and the instruction from network device 102, simultaneously receives the PRS on CC1 and the SSB on CC2. Positioning measurement results are obtained based on the PRS and reported to LMF 103 via network device 102. Mobility measurement results are obtained based on the SSB and reported to network device 102. In this example, no scheduling of Type II downlink signals such as PDCCH is performed during the measurement period.
[0174] In other examples, LMF103 may also have PRS configured on both CC1 and CC2. Network device 102 may also send PRS on CC1 and CC2, while sending SSB on CC3. The SCS is different between PRS and SSB.
[0175] In this embodiment of the disclosure, in scenarios where the SCS between signals are different, when the user equipment 101 supports the first capability and the second capability, the network device 102 can combine the user equipment 101 with the capability to send PRS and the first type of downlink signal on different carriers. Thus, in the scenario where the user equipment 101 performs positioning measurement under multiple carriers, mobility measurement can also be performed. However, the network device 102 does not perform other downlink data scheduling during this measurement.
[0176] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 6 , Figure 6 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 6 As shown, the method includes steps S601 to S604, specifically:
[0177] In step S601, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 supports the first capability and the third capability, but does not support the second capability.
[0178] The first capability corresponds to the ability to receive PRS and the set downlink signal on different carriers at the same time domain location, with the PRS and the set downlink signal having the same subcarrier spacing (SCS).
[0179] The second capability corresponds to the ability to receive PRS and Type I downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type I downlink signal are different.
[0180] The third capability corresponds to the capability to receive PRS and Type II downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type II downlink signal are different.
[0181] In step S602, network device 102 receives capability information.
[0182] In step S603, network device 102 transmits the PRS and the signal with higher priority among the first type of downlink signals on the first carrier in the multi-carrier at the same time domain location, and transmits the second type of downlink signal on the second carrier in the multi-carrier at the same time domain location.
[0183] In this context, "first" or "second" in "first carrier" or "second carrier" is used only to distinguish different carriers, not to limit the number of carriers. For example, "first carrier" or "second carrier" may include at least one.
[0184] In some possible implementations, network device 102 may send indication information to user equipment 101, which indicates the priority of the first type downlink signal and the PRS.
[0185] In one example, the PRS has a high priority, and network device 102 transmits the PRS on the first carrier in a multi-carrier configuration.
[0186] In step S604, user equipment 101 receives the higher priority signal between PRS and first type downlink signal on the first carrier in the multi-carrier at the same time domain location, and receives the second type downlink signal on the second carrier in the multi-carrier at the same time domain location.
[0187] In some possible implementations, the PRS has a high priority, and the user equipment 101 receives the PRS on the first carrier to perform positioning measurements.
[0188] For example, network device 102 simultaneously transmits a PRS on CC1 and a PDCCH on CC2 at time t1. User equipment 101 simultaneously receives a PRS on CC1 and a PDCCH on CC2 at time t2. It is understood that this embodiment is only intended to illustrate the ability of user equipment 101 to simultaneously receive different signals on multiple carriers. In actual applications, the transmission and processing delays of different signals may differ, and the same time-domain position where network device 102 transmits different signals may correspond to the same time-domain interval. The transmission time must be sufficient for user equipment 101 to simultaneously receive signals on different carriers.
[0189] In this embodiment of the disclosure, when the SCS between the PRS and the second type of downlink signal is different, and the user equipment 101 supports the first capability and the third capability, the network device 102 can combine the user equipment 101 with the capability to send the PRS and the second type of downlink signal on different carriers. Thus, in the scenario where the user equipment 101 performs positioning measurement under multiple carriers, downlink data scheduling can also be performed. However, the network device 102 does not configure mobility measurement during this period.
[0190] This disclosure provides a method for transmitting and receiving capability information. (Refer to...) Figure 7 , Figure 7 This is a method for transmitting and receiving capability information according to an exemplary embodiment. For example... Figure 7 As shown, the method includes steps S701 to S704, specifically:
[0191] In step S701, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 supports a first capability, a second capability, and a third capability.
[0192] The first capability corresponds to the ability to receive PRS and the set downlink signal on different carriers at the same time domain location, with the PRS and the set downlink signal having the same subcarrier spacing (SCS).
[0193] The second capability corresponds to the ability to receive PRS and Type I downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type I downlink signal are different.
[0194] The third capability corresponds to the capability to receive PRS and Type II downlink signals on different carriers at the same time domain location when the PRS and the SCS of the Type II downlink signal are different.
[0195] Step S702, network device 102 receives capability information.
[0196] In step S703, network device 102 transmits PRS on the first carrier in the multi-carrier at the same time domain location, and transmits a first type downlink signal or a second type downlink signal on the second carrier in the multi-carrier at the same time domain location.
[0197] In step S704, user equipment 101 receives PRS on the first carrier of the multi-carrier at the same time domain location, and receives either a first type downlink signal or a second type downlink signal on the second carrier of the multi-carrier at the same time domain location.
[0198] For example, network device 102 simultaneously transmits a PRS on CC1 and an SSB or PDCCH on CC2 at time t1. User equipment 101 simultaneously receives a PRS on CC1 and an SSB or PDCCH on CC2 at time t2. It is understood that this embodiment is only intended to illustrate the ability of user equipment 101 to simultaneously receive different signals on multiple carriers. In actual applications, the transmission and processing delays of different signals may differ, and the same time-domain position where network device 102 transmits different signals may correspond to the same time-domain interval. The transmission time must be sufficient for user equipment 101 to simultaneously receive signals on different carriers.
[0199] In this embodiment of the disclosure, applicable to a communication scenario with two carriers, and where the PRS and the SCS between the set downlink signal are different, in this scenario, when the user equipment 101 supports the first capability, the second capability, and the third capability, the user equipment 101 receives the PRS on the first carrier to perform positioning measurement, and on the second carrier, it may receive the first type of downlink signal for mobility measurement, or receive the second type of downlink signal for data transmission.
[0200] The method for transmitting and receiving capability information in this embodiment of the present disclosure may include steps S701, S702, S703' and S704', specifically:
[0201] In step S701, user equipment 101 sends capability information to network device 102. The capability information includes that user equipment 101 supports a first capability, a second capability, and a third capability.
[0202] Step S702, network device 102 receives capability information.
[0203] In step S703', network device 102 transmits PRS on the first carrier in the multi-carrier at the same time domain location, transmits a first type downlink signal on the second carrier in the multi-carrier at the same time domain location, and transmits a second type downlink signal on the third carrier in the multi-carrier at the same time domain location.
[0204] In step S704', user equipment 101 receives the PRS on the first carrier of the multi-carrier at the same time domain location, and receives the first type downlink signal on the second carrier of the multi-carrier and the second type downlink signal on the third carrier of the multi-carrier at the same time domain location.
[0205] For example, network device 102 simultaneously transmits a PRS on CC1, an SSB on CC2, and a PDCCH on CC3 at time t1. User equipment 101 simultaneously receives a PRS on CC1, an SSB on CC2, and a PDCCH on CC3 at time t2. It is understood that time-domain positions may correspond to time-domain intervals. This embodiment is only to illustrate the ability of user equipment 101 to simultaneously receive different signals on multiple carriers. In actual applications, the transmission delay and processing delay of different signals may differ, and the same time-domain position of network device 102 transmitting different signals may correspond to the same time-domain interval. The transmission time must meet the requirement that user equipment 101 can simultaneously receive signals on different carriers.
[0206] In this context, the terms "first," "second," or "third" in "first carrier," "second carrier," or "third carrier" are used only to distinguish different carriers, not to limit the number of carriers. For example, "first carrier," "second carrier," or "third carrier" may include at least one.
[0207] In this embodiment of the disclosure, when the communication scenario with two or more carriers is applicable and the SCS between the PRS and the set downlink signal is different, in this scenario, when the user equipment 101 supports the first capability, the second capability and the third capability, the user equipment 101 receives the PRS on the first carrier to realize positioning measurement, receives the first type of downlink signal on the second carrier to perform mobility measurement, and simultaneously receives the second type of downlink signal to perform data transmission.
