Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202111307503.X, entitled "COMMUNICATION METHOD AND APPARATUS," filed with the State Intellectual Property Office of China on November 5, 2021, which is incorporated herein by reference in its entirety.

[0002] The present application relates to the field of communication technology, and in particular to communication methods and devices. [Background technology]

[0003] In a communication system, a network device can configure a bandwidth part (BWP) of a terminal device according to the bandwidth capability of the terminal device. For example, for a low-capability terminal device (RedCap UE), the bandwidth of the BWP configured by the network device for the RedCap UE cannot exceed 20 MHz.

[0004] Since the terminal device is a mobile device, the state of the radio channel between the terminal device and the network device is constantly changing. After the terminal device accesses the serving cell, it can perform channel measurement, radio link monitoring (RLM) measurement, or beam failure recovery (BFR) measurement of the serving cell in radio resource management (RRM) measurement based on the cell define synchronization signal block (CD-SSB) of the current serving cell.

[0005] If the active BWP configured by the network device for the terminal device includes CD-SSB, all terminal devices will concentrate on the 20 MHz frequency domain resource including CD-SSB, causing an imbalance in the load of frequency domain resources. If the active BWP configured by the network device for the terminal device does not include CD-SSB, the terminal device must switch to the frequency domain resource where CD-SSB is located through frequency tuning for measurement, and then return to the active BWP after measurement. As a result, the terminal device's power consumption and complexity increase, and communication may be interrupted.

[0006] Therefore, how to improve the communication performance of terminal devices and how to improve the resource utilization of communication systems has become an urgent technical issue to be solved. Summary of the Invention

[0007] In view of this, the present application provides a communication method and a communication device for improving the communication performance of a terminal device and improving resource utilization of a communication system.

[0008] According to a first aspect, an embodiment of the present application provides a communication method, the method including: a step of receiving, by a terminal device, measurement information from a network device, the measurement information indicating one or more measurement objects, the measurement information including one or more of information on the measurement objects of a serving cell, information on intra-frequency measurements of a neighboring cell, and information on inter-frequency measurements of the neighboring cell; and a step of performing, by the terminal device, one or more measurements of a radio resource management (RRM) measurement, a radio link monitoring (RLM) measurement, and a beam failure recovery (BFR) measurement based on reference signals associated with the one or more measurement objects corresponding to a first bandwidth portion (BWP).

[0009] According to the first aspect, when performing measurements, the terminal device can perform the measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP. The measurement object indicated by the measurement information transmitted from the network device to the terminal device can be one or more of information related to the measurement object of the serving cell, information related to intra-frequency measurements of neighboring cells, or information related to inter-frequency measurements of neighboring cells. This can prevent all terminal devices from concentrating on the 20 MHz frequency domain resource of CD-SSB, thereby balancing the load on the frequency domain resource. Because the terminal device can perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP, if the first BWP does not include CD-SSB, the terminal device does not need to switch to the frequency domain resource where CD-SSB is located for measurements and then switch back to the first BWP. This can reduce the power consumption and complexity of the terminal device, improve the communication performance of the terminal device, and improve resource utilization of the communication system.

[0010] In a possible design, when the terminal device is in connected mode, the first BWP is the active BWP, or when the terminal device is in unconnected mode, the first BWP is the BWP on which the terminal device is camped.

[0011] Based on this possible design, when the terminal device is in a connected mode, the first BWP is an active BWP, or when the terminal device is in a non-connected mode, the first BWP is a BWP to which the terminal device camps, which provides a feasible solution for the terminal device to perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP.

[0012] In a possible design, the reference signals include one or more of a cell-defined synchronization signal block (CD-SSB), a non-cell-defined synchronization signal block (NCD-SSB), and channel state information (CSI-RS).

[0013] Based on this possible design, the reference signal associated with the measurement object may be CD-SSB, NCD-SSB, or CSI-RS. In this embodiment of the present application, measurements performed using measurement objects associated with NCD-SSB are introduced, and by specifying how the terminal device determines the measurement object and the reference signal, it is possible to avoid cases where measurement information needs to be frequently reconfigured.

[0014] In a possible design, different BWPs correspond to different measurement objects.

[0015] Based on this possible design, the network device can configure a corresponding measurement object for each BWP. When the BWP is an active BWP, the terminal device can perform measurements based on the measurement object corresponding to the BWP.

[0016] In a possible design, the measurement information is carried in the configuration information of the BWP, or the measurement information is carried in the configuration information of the serving cell.

[0017] Based on this possible design, the measurement information may be disposed in the configuration information of the BWP, and the terminal device may determine the measurement object corresponding to the BWP based on the received configuration information of the BWP. Alternatively, the measurement information may be disposed in the configuration information of the serving cell, and the terminal device may determine the measurement object based on the configuration information of the serving cell and further determine the measurement object corresponding to the BWP based on the BWP.

[0018] In a possible design, the measurement information is carried in configuration information of the serving cell, and the measurement information includes a plurality of measurement information, where a frequency domain resource of a reference signal associated with a measurement object corresponding to a first BWP is the same as a frequency domain resource of the first BWP, or a frequency domain resource of a reference signal associated with a measurement object corresponding to the first BWP falls within a frequency domain resource range of the first BWP.

[0019] Based on this possible design, the terminal device can determine a measurement object corresponding to the first BWP based on the frequency domain resource of the first BWP, which provides a feasible solution for the terminal device to determine the measurement object of the BWP.

[0020] In a possible design, the terminal device receives first signaling from the network device, the first signaling indicating that measurements are to be performed based on reference signals associated with one or more measurement objects corresponding to a first BWP, the first signaling being downlink control information (DCI) or medium access control control element (MAC CE) signaling.

[0021] Based on this possible design, the terminal device may determine to perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP based on the first signaling sent by the network device, which provides a feasible solution for the terminal device to perform measurements.

[0022] In a possible design, the terminal device determines information about intra-frequency measurements of neighboring cells based on the measurement information, where a frequency of a reference signal related to the intra-frequency measurements is the same as a frequency of a first reference signal, and the first reference signal is a reference signal related to a measurement object of a serving cell in a first BWP, or a frequency of a reference signal related to the intra-frequency measurements is the same as a frequency of a second reference signal, and the second reference signal is a reference signal related to a measurement object of a serving cell of the terminal device.

[0023] Based on this possible design, the terminal device can further determine information about intra-frequency measurements of the neighboring cell based on the first reference signal or the second reference signal, which provides a viable solution for the terminal device to perform intra-frequency measurements.

[0024] In a possible design, the measurement information further includes one or more of an identity of a serving cell of the measurement object and an identity of a neighboring cell of the measurement object.

[0025] Based on this possible design, the network device indicates the identity of the serving cell of the measurement object or the identity of the neighboring cell of the measurement object in the measurement information, so that the terminal device can determine whether the current measurement object is a measurement object of the serving cell or a measurement object of the neighboring cell based on the identity of the cell of the measurement object.

[0026] In a possible design, the number of measurement objects is equal to or less than the number of BWPs that the network device has configured for the terminal device.

[0027] In a possible design, the RRM measurements include intra-frequency measurements and inter-frequency measurements, and the total number of frequencies corresponding to the intra-frequency measurements and inter-frequency measurements supported by the terminal device is greater than eight.

[0028] In a possible design, the number of frequencies supported by the terminal device in the first measurement period is eight or less, the frequencies supported by the terminal device in different first measurement periods are different, and the first measurement period is the smallest value in the measurement periods corresponding to one or more measurement objects.

[0029] Based on the above two possible designs, the total number of frequencies corresponding to intra-frequency measurements and inter-frequency measurements supported by the terminal device is increased, so that after introducing NCD-SSB, the service quality of the network will not be affected due to the limited number of frequencies to be measured, or the measurement load of the terminal device will not be excessively heavy.

[0030] In a possible design, the measurement period of the NCD-SSB of the serving cell is equal to or greater than the measurement period of the CD-SSB of the serving cell.

[0031] Based on this possible design, the resources occupied are not excessive and the measurement load of the terminal device does not increase.

[0032] In a possible design, the terminal device transmits first indicator information to the network device, where the first indicator information indicates whether the terminal device supports performing RRM measurements, RLM measurements, or BFR measurements based on NCD-SSB.

[0033] Based on this possible design, if the terminal device supports RRM measurements, RLM measurements, or BFR measurements based on NCD-SSB, when configuring a measurement object for the terminal device, the network device can configure a measurement object related to NCD-SSB.

[0034] In a possible design, the terminal device transmits second indicator information to the network device, the second indicator information indicating a maximum number of frequencies supported by the terminal device, the maximum number being greater than 8.

[0035] Based on this possible design, since the total number of frequencies supported by the terminal device increases, after introducing NCD-SSB, the service quality of the network will not be affected due to the limited number of frequencies to be measured, or the measurement load of the terminal device will not be excessively heavy.

[0036] In a possible design, the terminal device reports to the network device measurement results, the measurement results being measurement results obtained by the terminal device by performing one or more of radio resource management (RRM) measurements, radio link monitoring (RLM) measurements, and beam failure recovery (BFR) measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP.

[0039] In a possible design, the reference signals include one or more of a cell-defined synchronization signal block (CD-SSB), a non-cell-defined synchronization signal block (NCD-SSB), and channel state information (CSI-RS).

[0040] In a possible design, different BWPs correspond to different measurement objects.

[0041] In a possible design, the measurement information may be carried in the configuration information of the BWP, or the measurement information may be carried in the configuration information of the serving cell.

[0042] In a possible design, the measurement information is carried in configuration information of the serving cell, and the measurement information includes a plurality of measurement information, where a frequency domain resource of a reference signal associated with a measurement object corresponding to a first BWP is the same as a frequency domain resource of the first BWP, or a frequency domain resource of a reference signal associated with a measurement object corresponding to the first BWP falls within a frequency domain resource range of the first BWP.

[0043] In one possible design, the transceiver module is further configured to receive first signaling from the network device, the first signaling indicating performing measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP, the first signaling being downlink control information (DCI) or medium access control element (MAC CE) signaling.

[0044] In a possible design, the processing module is further configured to determine, based on the measurement information, information regarding intra-frequency measurements of the neighboring cell, where a frequency of a reference signal related to the intra-frequency measurements is the same as a frequency of a first reference signal, the first reference signal being a reference signal related to a measurement object of a serving cell in the first BWP, or a frequency of a reference signal related to the intra-frequency measurements is the same as a frequency of a second reference signal, the second reference signal being a reference signal related to a measurement object of a serving cell of the terminal device.

[0107] Before describing the embodiments of the present application, technical terms used in the embodiments of the present application will be explained.

[0108] The fifth generation (5G) mobile communication system: Mobile communication technology has greatly changed people's lives, but people's pursuit of higher performance mobile communication technology never stops. 5G communication systems are emerging to address the explosive growth in mobile data traffic, the large-scale mobile communication device connections, and various new services and application scenarios that will emerge in the future. The International Telecommunication Union (ITU) has specified three main application scenarios for 5G communication systems and future mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC), and massive machine type communication (mMTC).

[0109] Reduced Capability User Equipment (RedCap UE): In the standard, a terminal device for mMTC services may be referred to as a RedCap UE or a low-complexity terminal device. This type of terminal device may be less complex than another terminal device in terms of bandwidth, power consumption, and number of antennas, for example, narrower bandwidth, lower power consumption, and fewer antennas. This type of terminal device may also be referred to as a lightweight (NR light, NRL) terminal device.

[0110] Bandwidth part (BWP): A 5G communication system can support a wide bandwidth. For example, an eMBB UE (or a non-RedCap UE) can support a channel bandwidth of 100 MHz. The concept of BWP is introduced into the 5G standard for energy saving and other requirements, and a network device can configure the bandwidth of the BWP at the granularity of a resource block (RB). Because the bandwidth capability of a RedCap UE is limited (for example, the maximum channel bandwidth supported is small, e.g., 20 MHz, while the maximum channel bandwidth supported by a non-RedCap UE is 100 MHz), the BWP bandwidth configured by the network device for a RedCap UE cannot exceed the capability of the RedCap UE, i.e., it cannot exceed 20 MHz.

[0111] Since the UE is a mobile entity and the wireless channel environment is constantly changing, the status of the wireless channel between the UE and the network device is constantly changing. Therefore, after accessing the serving cell, the UE needs to further perform channel measurement of the serving cell and neighboring cells based on the network configuration and report the channel measurement result to the network device, so that the network device can better allocate resources to the UE based on the channel status.

[0112] Radio resource management (RRM): RRM can be used for mobility measurements, including measurements of reference signals of the serving cell and neighboring cells. According to a communication protocol, a network device can configure multiple measurement objects (MOs) for a UE, and each MO can be associated with one reference signal used for measurements. The reference signal of the serving cell may be a cell-defined synchronization signal block (CD-SSB). For a UE, there is only one CD-SSB in a serving cell, but there may be multiple NCD-SSBs. If the bandwidth of the active BWP (i.e., the BWP currently transmitting information) does not include a CD-SSB, the UE can only frequency tune to the frequency domain resource where the CD-SSB is located for measurement and then return to the active BWP after the measurement to measure the channel quality of the serving cell.

[0113] Radio link monitoring (RLM) or beam failure recovery (BFR) measurements: These relate to measurements of the serving cell only, i.e. CD-SSB is used for the measurements.

[0114] When a network is deployed in frequency range 1 (FR1), the bandwidth capability of a terminal device is limited. For example, the bandwidth of a serving cell or carrier may be 100 MHz, but the maximum bandwidth of a BWP configured for the terminal device may be only 20 MHz. Thus, if the active BWP configured for the terminal device by the network device includes CD-SSB, all terminal devices will converge on the 20 MHz frequency domain resource including CD-SSB, causing an imbalance in the load of frequency domain resources. If the active BWP configured for the terminal device by the network device does not include CD-SSB, the terminal device must switch to the frequency domain resource where CD-SSB is located through frequency tuning for measurement, and then return to the active BWP after the measurement. This results in increased power consumption and complexity for the terminal device, and may result in communication interruptions.

[0115] Therefore, how to improve the communication performance of terminal devices and how to improve the resource utilization of communication systems has become an urgent technical issue to be solved.

[0116] To solve this problem, one embodiment of the present application provides a communication method. In this method, a terminal device can receive measurement information from a network device, where the measurement information indicates one or more measurement objects, and the measurement information includes one or more of information on measurement objects of a serving cell, information on intra-frequency measurements of neighboring cells, and information on inter-frequency measurements of neighboring cells. The terminal device performs one or more of radio resource management (RRM) measurements, radio link monitoring (RLM) measurements, and beam failure recovery (BFR) measurements based on reference signals related to the one or more measurement objects corresponding to a first BWP.

[0117] In this embodiment of the present application, when performing measurements, the terminal device can perform the measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP. The measurement object indicated by the measurement information transmitted from the network device to the terminal device can be one or more of information related to the measurement object of the serving cell, information related to intra-frequency measurements of neighboring cells, or information related to inter-frequency measurements of neighboring cells. This can prevent all terminal devices from concentrating on the 20 MHz frequency domain resources of CD-SSB, thereby distributing the load on frequency domain resources. Because the terminal device can perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP, if the first BWP does not include CD-SSB, the terminal device does not need to switch to the region resources where CD-SSB is located for measurements and then switch back to the first BWP. This can reduce the power consumption and complexity of the terminal device, improve the communication performance of the terminal device, and improve resource utilization of the communication system.

[0118] The implementation of this embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Note that the compositional structure shown in Figure 2 does not constitute a limitation on the communications device.

[0144] In embodiments of the present application, a chip system may include a chip, or may include a chip and another separate device.

[0146] Referring to the communication system shown in FIG. 1, the following describes a communication method provided in an embodiment of the present application with reference to FIG. 3. The terminal device may be any terminal device in the communication system shown in FIG. 1, and the network device may be any network device in the communication system shown in FIG. 1.

The processing performed by a single execution unit (terminal device or network device) shown in the embodiment of the present application may be divided into processes processed by multiple execution units, and these execution units may be logically and / or physically separated. For example, the processing performed by the network device may be divided into processes performed by at least one of a central unit (CU), a distribution unit (DU), and a radio unit (RU). This is not limited thereto.

[0147] 3 is a flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 3, the method may include the following steps:

[0148] Step 301: The network device sends measurement information to the terminal device, and the terminal device receives measurement information from the network device in response.

[0149] The measurement information may indicate one or more measurement objects, and may include one or more of information about measurement objects of the serving cell, information about intra-frequency measurements of neighboring cells, and information about inter-frequency measurements of neighboring cells.

[0150] The reference signal associated with each measurement object may include one or more of CD-SSB, NCD-SSB, and channel-state information reference signal (CSI-RS). For example, the reference signal associated with the measurement object is a CD-SSB used for measuring the serving cell. For example, the reference signal associated with the measurement object is an NCD-SSB used for measuring the serving cell. For example, the reference signal associated with the measurement object is a CD-SSB used for measuring a neighboring cell. For example, the reference signal associated with the measurement object is an NCD-SSB used for measuring the neighboring cell.

[0151] For example, the measurement information may include identification information of a reference signal associated with the measurement object, e.g., the identification information of the reference signal indicates that the reference signal is one or more of CD-SSB, NCD-SSB, and CSI-RS.

[0152] When the measurement information is information about an intra-frequency measurement of a neighboring cell or information about an inter-frequency measurement of a neighboring cell, whether it is an intra-frequency measurement or an inter-frequency measurement can be determined based on the frequency of the reference signal associated with the measurement object, and it is not necessary to take into account whether the reference signal of the neighboring cell is CD-SSB or NCD-SSB.

[0153] For example, the period of NCD-SSB is equal to or greater than the period of CD-SSB. NCD-SSB is a reference signal used for measurement. The period of NCD-SSB is configured by the network device. CD-SSB is a reference signal used for measurement. The period of CD-SSB is configured by the network device. In this way, it is possible to prevent the NCD-SSB used for measurement from occupying excessive processing resources, and the measurement load on the terminal device is not increased. This also makes it possible to avoid a situation where resources available for data transmission are reduced due to excessive time-frequency resources being occupied by the network.

[0154] For example, to reduce the complexity of measurements on the terminal device, the maximum number of NCD-SSBs that can be included in the first resource can be limited. For example, the first resource is a carrier or a BWP. For example, only one SSB can be included in the first resource. Since the maximum number of NCD-SSBs included in the first resource is limited, the measurement load on the terminal device caused by a large number of NCD-SSBs is not excessively heavy.

[0155] For example, the maximum number N_max of NCD-SSBs that the network device can configure for the terminal device in the first resource is limited. For example, the maximum number of NCD-SSBs supported by the terminal device in the first resource is limited. For example, the network device configures NCD-SSB information for the terminal device using signaling. For example, the terminal device obtains the NCD-SSB information configured for the terminal device by the network device by receiving signaling. The NCD-SSB information includes one or more of frequency information related to the NCD-SSB, information on the number of NCD-SSBs, or information on the maximum number of NCD-SSBs. The NCD-SSB information may be associated with a BWP, or the NCD-SSB information may be associated with a carrier. Alternatively, the maximum number of NCD-SSBs supported by the network device is limited.

[0156] For example, the maximum number of NCD-SSBs may be associated with the bandwidth of the first resource.

[0157] For example, the bandwidth of the first resource is 40 MHz, and N_max=1 or 2. For example, the bandwidth of the first resource is 100 MHz, and N_max=4 or 5. For example, the first resource is a BWP, and N_max=1.

[0158] Optionally, the maximum number Ns of reference signals that can be included in the first resource is limited. For example, the first resource is a BWP and the reference signals are CD-SSB and / or NCD-SSB. For example, Ns=1. For example, the BWP includes at most one complete SSB. SSB is used for measurements. The SSB may be CD-SSB or NCD-SSB.

[0159] Optionally, the NCD-SSB used for measurement may not contain a master information block (MIB), or the NCD-SSB used for measurement may be used for reinterpretation or for data transmission.

[0160] In a possible design, the frequency of the reference signal associated with the intra-frequency measurement is the same as the frequency of the first reference signal. The frequency of the reference signal associated with the inter-frequency measurement is different from the frequency of the first reference signal. In this way, the terminal device only needs to maintain intra-frequency measurement information for one frequency at a time, thereby reducing the power consumption and complexity of the terminal device.

[0161] The first reference signal may be a reference signal associated with a measurement object of a serving cell in a first BWP.

[0162] If the terminal is in connected mode, the first BWP is the active BWP. If the terminal is in unconnected mode, the first BWP is the BWP the terminal is camped on.

[0163] In another possible design, the frequency of the reference signal related to the intra-frequency measurement is the same as the frequency of the second reference signal. The frequency of the reference signal related to the inter-frequency measurement is different from the frequency of the second reference signal. In this way, since the terminal device simultaneously maintains all intra-frequency measurement information of frequencies related to all measurement objects of the serving cell, the terminal device and the network device can better obtain the channel quality of the terminal device in each bandwidth portion (BWP) of the frequency domain resource, thereby providing more comprehensive reference information for the network device to perform scheduling.

[0164] The second reference signal is a reference signal related to a measurement object of the serving cell of the terminal device. The second reference signal is a reference signal related to any measurement object of the serving cell of the terminal device. For example, if the serving cell of the terminal device includes five measurement objects, any one of the reference signals related to the five measurement objects is considered to be the second reference signal.

[0165] For example, a network device may configure one or more BWPs for a terminal device, and each BWP may correspond to one or more measurement objects.

[0166] The frequency domain resource of the reference signal associated with the measurement object corresponding to each BWP may be the same as the frequency domain resource of the BWP, or the frequency domain resource of the reference signal associated with the measurement object corresponding to each BWP may fall within the frequency domain resource range of the BWP, for example, the frequency domain resource is a bandwidth.

[0167] For example, the measurement objects configured by the network device for the terminal device include a first measurement object, a second measurement object, and a third measurement object, and the BWPs configured by the network device for the terminal device include BWP1 and BWP2, where BWP1 may correspond to the first measurement object, and BWP2 may correspond to the second measurement object and the third measurement object.

[0168] Note that the measurement objects corresponding to different BWPs may be the same or different.

[0169] For example, the BWPs configured by the network device for the terminal device include BWP1, BWP2, and BWP3. The measurement objects corresponding to BWP1 and BWP2 may be different. The measurement objects corresponding to BWP1 and BWP3 may be the same.

[0170] In a first possible design, the network device carries measurement information and transmits configuration information related to the BWP to the terminal device, which can also be described as the measurement information being carried in the configuration information of the BWP.

[0171] The network device may carry measurement information corresponding to each BWP and transmit configuration information relating to each BWP (eg, BWP-DownlinkDedicated) to the terminal device.

[0172] For example, BWPs configured by a network device for a terminal device include BWP1, BWP2, and BWP3. The configuration information of BWP1 may include measurement information corresponding to BWP1, and the measurement information corresponding to BWP1 may indicate one or more measurement objects corresponding to BWP1. The configuration information of BWP2 may include measurement information corresponding to BWP2, and the measurement information corresponding to BWP2 may indicate one or more measurement objects corresponding to BWP2. The configuration information of BWP3 may include measurement information corresponding to BWP3, and the measurement information corresponding to BWP3 may indicate one or more measurement objects corresponding to BWP3.

[0173] The measurement information may include one or more of measurement object information, measurement object list information, and SSB information.

[0174] The measurement object information may include identification information of one or more measurement objects, and the identification information may be an MO ID or other identification information capable of indicating a measurement object. The measurement object list information may include identification information of one or more measurement objects. The measurement object list may be an MO list or a MeasObjectToAddModList. The SSB information may include one or more of SSB frequency information, SSB center frequency, and SSB index.

[0175] Optionally, if the measurement information includes measurement object list information, the measurement object list information further includes an index of the measurement object list.

[0176] For BWPs corresponding to the same measurement object, the measurement object list indices included in the measurement information of the BWPs corresponding to the same measurement object may be the same.For BWPs corresponding to different measurement objects, the measurement object list indices included in the measurement information of the BWPs corresponding to the different measurement objects may be different.

[0177] For example, the BWPs configured by the network device for the terminal device include BWP1, BWP2, and BWP3. Assume that the measurement objects corresponding to BWP1 and BWP2 are different, the measurement objects corresponding to BWP1 and BWP3 are the same, the indexes of the measurement object lists corresponding to BWP1 and BWP2 are different, and the indexes of the measurement object lists corresponding to BWP1 and BWP3 are the same.

[0178] Alternatively, the measurement object list indices contained in the configuration information of different BWPs may be different.

[0179] For example, the BWPs configured by the network device for the terminal device include BWP1, BWP2, and BWP3, where the index of the measurement object list corresponding to BWP1 may be index 1, the index of the measurement object list corresponding to BWP2 may be index 2, and the index of the measurement object list corresponding to BWP3 may be index 3.

[0180] It should be noted that if the BWP configuration information configured by the network device for the terminal device includes measurement information corresponding to the BWP and the BWP is the first BWP, the terminal device can perform measurements based on the measurement information corresponding to the first BWP. If the BWP configuration information configured by the network device for the terminal device does not include measurement information corresponding to the BWP and the BWP is the first BWP, the terminal device can perform measurements based on the CD-SSB of the serving cell (i.e., if the active BWP includes the CD-SSB of the serving cell, the terminal device performs measurements based on the CD-SSB of the serving cell). Alternatively, if the active BWP does not include the CD-SSB of the serving cell, the terminal device switches to the CD-SSB of the serving cell for measurements, and then switches back to the active BWP).

[0181] For example, the measurement information may further include one or more of an identification information of a serving cell of the measurement object and an identification information of a neighboring cell of the measurement object.

[0182] The network device indicates the identification information of the serving cell of the measurement object in the measurement information, or the network device indicates the identification information of the neighboring cell of the measurement object in the measurement information, so that the terminal device can determine whether the current measurement object is a measurement object of the serving cell or a measurement object of a neighboring cell based on the identification information of the cell of the measurement object.

[0183] In a second possible design, the network device may transmit configuration information (e.g., ServingCellConfig) that carries the measurement information and relates to the serving cell to the terminal device, or may describe that the measurement information is carried in the configuration information of the serving cell.

[0184] The measurement information may include one or more of measurement object information, information about one or more measurement object lists, and SSB information.

[0185] The measurement object information may include identification information of one or more measurement objects. The identification information may be an MO ID or other identification information capable of indicating a measurement object. The measurement object list information may include identification information of one or more measurement objects. The measurement object list may be an MO list or a MeasObjectToAddModList. The SSB information may include one or more of SSB frequency information and an SSB index.

[0186] For example, a network device may configure one or more measurement objects and use one measurement object list to indicate one or more measurement objects configured by the network device.

[0187] In this example, the terminal device can use the resource range of the BWP to determine the measurement object corresponding to the BWP.

[0188] For example, the resource range is bandwidth.

[0189] The frequency domain resources of the reference signals associated with the measurement objects corresponding to each BWP may be the same as the frequency domain resources of the BWP, or the frequency domain resources of the reference signals associated with the measurement objects corresponding to each BWP fall within the frequency domain resource range of the BWP.

[0190] In yet another example, the network device may configure, for each BWP, a measurement object corresponding to each BWP, and may use multiple measurement object lists to indicate the measurement objects that the network device has configured for multiple BWPs.

[0191] In this example, the terminal device can use the resource range of the BWP to determine the measurement object corresponding to the BWP.

[0192] The frequency domain resources of the reference signals associated with the measurement objects corresponding to each BWP may be the same as the frequency domain resources of the BWP, or the frequency domain resources of the reference signals associated with the measurement objects corresponding to each BWP fall within the frequency domain resource range of the BWP.

[0193] Alternatively, if the measurement object list information further includes an index of the measurement object list, the terminal device can use the index corresponding to the BWP to determine the measurement object list corresponding to the BWP and determine the measurement object corresponding to the BWP.

[0194] For BWPs corresponding to the same measurement object, the indexes of the measurement object lists corresponding to the BWPs corresponding to the same measurement object may be the same.For BWPs corresponding to different measurement objects, the indexes of the measurement object lists corresponding to the BWPs corresponding to the different measurement objects may be different.

[0195] For example, the BWPs configured by the network device for the terminal device include BWP1, BWP2, and BWP3. Assume that the measurement objects corresponding to BWP1 and BWP2 are different, the measurement objects corresponding to BWP1 and BWP3 are the same, the indices of the measurement object lists corresponding to BWP1 and BWP2 are different, and the indices of the measurement object lists corresponding to BWP1 and BWP3 are the same.

[0196] Alternatively, the measurement object list indices included in the configuration information of different BWPs may be different.

[0197] For example, the BWPs configured by the network device for the terminal device include BWP1, BWP2, and BWP3, where the index of the measurement object list corresponding to BWP1 may be index 1, the index of the measurement object list corresponding to BWP2 may be index 2, and the index of the measurement object list corresponding to BWP3 may be index 3.

[0198] For example, the number of measurement objects indicated by the measurement information may be equal to or less than the number of BWPs configured by the network device for the terminal device. Alternatively, the number of reference signals associated with the measurement objects indicated by the measurement information may be equal to or less than the number of BWPs configured by the network device for the terminal device. For example, the reference signals may be one or more of NCD-SSB, CD-SSB, and CSI-RS.

[0199] For example, as shown in Figure 4, the measurement information included in the configuration information of the serving cell indicates five measurement objects. Assume that the five measurement objects are respectively associated with five SSBs, and the five SSBs may be CD-SSBs or NCD-SSBs. The five SSBs may correspond to different BWPs. For example, NCD-SSB1 corresponds to BWP1, NCD-SSB2 corresponds to BWP2, CD-SSB corresponds to BWP3, NCD-SSB3 corresponds to BWP4, and NCD-SSB4 corresponds to BWP5.

[0200] Optionally, the network device may send first signaling to the terminal device, and the terminal device may perform measurements based on the first signaling.

[0201] The first signaling may indicate performing measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP.

[0202] For example, the first signaling may be downlink control information (DCI) or media access control element (MAC CE) signaling. The network device uses dynamic signaling to indicate the measurement object information, so that the network device can perform measurement configuration more flexibly based on the network status.

[0203] The DCI may indicate a BWP switch.

[0204] The network device may send a first signaling to dynamically indicate to the terminal device to perform measurements based on one or more measurement objects corresponding to the first BWP. Alternatively, the network device may send a first signaling to dynamically indicate to the terminal device to perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP. Thus, the network device may obtain better channel conditions based on the measurement results reported by the terminal device.

[0205] It should be noted that when one BWP corresponds to multiple measurement objects, the terminal device can maintain multiple measurement sets in one BWP. When one BWP corresponds to one measurement object, the terminal device can maintain one set of measurements in one BWP. When one BWP corresponds to one measurement object, the terminal device can prevent maintaining multiple measurement sets in one BWP, and can prevent the terminal device from occupying a large amount of resources.

[0206] Optionally, the first indicator information transmitted by the terminal device is received. The network device receives the first indicator information transmitted by the terminal device. Thus, the network device can better configure appropriate measurement resources for the terminal device based on the capabilities of the terminal device.

[0207] For example, the first indicator information may indicate whether the terminal device supports RRM measurements, RLM measurements, beam-related measurements, or BFR measurements based on NCD-SSB.

[0208] For example, the first index information is { The terminal device supports a first resource including NCD-SSB; The terminal device does not support the first resource, including NCD-SSB; Supports the terminal device to perform one or more of RRM measurements, RLM measurements, beam-related measurements, or BFR measurements based on NCD-SSB; The terminal device does not support performing one or more of RRM measurements, RLM measurements, beam-related measurements, or BFR measurements based on NCD-SSB; Supports the terminal device to perform RRM measurements of the serving cell based on NCD-SSB; The terminal device does not support making RRM measurements of the serving cell based on NCD-SSB; Supports the terminal device to perform RRM measurements of non-serving cells (or neighboring cells) based on NCD-SSB; The terminal device does not support performing RRM measurements of non-serving cells (or neighboring cells) based on NCD-SSB; The terminal equipment supports NCD-SSB and CD-SSB quasi-collocation (QCL); The terminal device supports non-quasi-collocation of NCD-SSB and CD-SSB. The terminal device supports a PCI for NCD-SSB that is different from the PCI for CD-SSB; The terminal device supports the PCI of NCD-SSB that is the same as the PCI of CD-SSB; The terminal device supports CD-SSB measurements using measurement gaps; The terminal equipment does not support CD-SSB measurements using measurement gaps; The terminal device supports NCD-SSB durations that are different from CD-SSB durations; The terminal device supports an NCD-SSB duration that is the same as the CD-SSB duration; The terminal device supports NCD-SSB transmission power that is different from CD-SSB transmission power; The terminal device supports NCD-SSB transmission power that is the same as CD-SSB transmission power; The number of NCD-SSBs supported by the terminal device on one carrier; The number of NCD-SSBs that the terminal equipment can measure on one carrier; The number of NCD-SSBs supported by the terminal device in one BWP; and It can indicate one or more of the NCD-SSBs that the terminal device can measure in one BWP.

[0209] For example, the first resource is a BWP or a carrier.

[0210] For example, the first indicator information indicates one or more of: that the terminal device supports a first resource that does not include SSB and / or CORESET#0; and that the terminal device supports a first resource that includes NCD-SSB.

[0211] For example, the first indicator information is 1 bit. When the bit state of the first indicator information is 0, the first indicator information indicates that the terminal device supports the first resource that does not include SSB and / or CORESET#0. When the bit state of the first indicator information is 1, the first indicator information indicates that the terminal device supports the first resource that includes NCD-SSB. Alternatively, when the bit state of the first indicator information is 1, the first indicator information indicates that the terminal device supports the first resource that does not include SSB and / or CORESET#0. Alternatively, when the bit state of the first indicator information is 0, the first indicator information indicates that the terminal device supports the first resource that includes NCD-SSB.

[0212] If the terminal device supports RRM measurements, RLM measurements, beam-related measurements, or BFR measurements based on NCD-SSB, when configuring a measurement object for the terminal device, the network device may configure a measurement object related to NCD-SSB.

[0213] Optionally, the network device may further receive second indicator information transmitted by the terminal device, where the second indicator information may indicate a maximum number of frequencies supported by the terminal device. For example, the frequency may be a frequency or a center frequency of a measurement reference signal. For example, the measurement may be an intra-frequency measurement and / or an inter-frequency measurement.

[0214] For example, the maximum value may be equal to or greater than 8. For example, the maximum value may be 8, 10, 12, 14, 16, or the like.

[0215] It should be noted that the total number of frequencies corresponding to intra-frequency and inter-frequency measurements supported by the terminal device may be greater than eight.

[0216] The number of frequencies supported by the terminal device in the first measurement period may be equal to or less than 8. The frequencies supported by the terminal device in different first measurement periods may be the same or different. The first measurement period is the smallest of the measurement periods corresponding to one or more measurement objects.

[0217] For example, the first measurement period includes a first measurement period 1, a first measurement period 2, and a first measurement period 3. The frequencies supported by the terminal device in the first measurement period 1 may be the same as the frequencies supported in the first measurement period 2, and the frequencies supported by the terminal device in the first measurement period 1 may be different from the frequencies supported in the first measurement period 3.

[0218] Since the total number of frequencies corresponding to intra-frequency measurements and inter-frequency measurements supported by the terminal device increases, after the introduction of NCD-SSB, the network service quality will not be affected due to the limited number of frequencies to be measured, or the measurement load of the terminal device will not be excessively heavy.

[0219] Optionally, when the network device indicates SSB to the terminal device, the measurement filtering and reporting for CD-SSB and NCD-SSB may be different, and the network device may indicate to the terminal device whether the SSB is CD-SSB or NCD-SSB.

[0220] The network device may use the configuration information to indicate to the terminal device whether the SSB is a CD-SSB or an NCD-SSB, for example, the configuration information being one or more of RRC configuration information, serving cell configuration information, and BWP configuration information.

[0221] For example, the first parameter of NCD-SSB is configured in the same manner as the first parameter of CD-SSB. For example, the first parameter is at least one of subcarrier spacing, transmission power, and reference signal index. For example, the transmission power is at least one of primary synchronization signal transmission power and secondary synchronization signal transmission power. For example, the reference signal index is an index bitmap. For example, the reference signal index indicates time domain information of reference signals transmitted by the network device. For example, the index includes an 8-bit number, and the bitmap 10001000 indicates that the 0th reference signal and the 4th reference signal are transmitted or used for measurement. Specifically, for example, the configuration information of NCD-SSB does not include the first parameter. For example, the terminal device determines the first parameter information of NCD-SSB based on the first parameter information of CD-SSB.

[0222] For example, the reference signal for measuring the neighbor cell may include at least CD-SSB, or the reference signal for measuring the neighbor cell may be only CD-SSB. When selecting the neighbor cell, if there are multiple reference signals and the measurement reference values ​​are different, the channel quality of the determined neighbor cell may be different, and as a result, the selected neighbor cell may not be the optimal neighbor cell. Therefore, CD-SSB is selected as the reference signal for the neighbor cell whenever possible, or the reference signal for the neighbor cell includes at least CD-SSB.

[0223] Step 302: The terminal device performs measurements based on reference signals associated with one or more measurement objects corresponding to a first BWP.

[0224] Optionally, the first BWP may be the active BWP when the terminal is in connected mode, or alternatively, the first BWP may be the BWP on which the terminal is camped when the terminal is in unconnected mode.

[0225] The measurements may include one or more of RRM measurements, RLM measurements, BFR measurements, beam measurements, and beam failure detection (BFD) measurements.

[0226] Note that if the measurement is an RRM measurement, the measurement information may be the measurement information described above in step 301. If the measurement is an RLM measurement, a BFR measurement, a beam measurement, or a beam failure detection (BFD) measurement, the measurement information may include SSB information. The measurement information may be carried in the configuration information of the BWP or may be carried in the downlink frequency information (FrequencyInfoDL).

[0227] When the measurement information is carried in the configuration information of the BWP, the terminal device can determine one or more measurement objects corresponding to the first BWP based on the configuration information of the first BWP.When the measurement information is carried in the configuration information of the serving cell, the terminal device can determine one or more measurement objects corresponding to the first BWP based on the frequency domain resources of the first BWP.

[0228] For example, the frequency domain resource of the reference signal associated with the measurement object corresponding to the first BWP may be the same as the frequency domain resource of the first BWP, or the frequency domain resource of the reference signal associated with the measurement object corresponding to the first BWP falls within the frequency domain resource range of the first BWP.

[0229] Optionally, when the first BWP corresponds to multiple measurement objects, the terminal device may select one measurement object for measurement from the multiple measurement objects corresponding to the first BWP, thereby reducing the power consumption of the terminal device.

[0230] For example, the terminal device can select a predefined measurement object for measurement from a plurality of measurement objects corresponding to the first BWP. Alternatively, the terminal device can select a measurement object related to CD-SSB for measurement from a plurality of measurement objects corresponding to the first BWP. Alternatively, the terminal device can select a measurement object with the smallest index for measurement from a plurality of measurement objects corresponding to the first BWP. Alternatively, the terminal device can select a measurement object corresponding to a reference signal whose frequency is closest to the center frequency of the first BWP for measurement from a plurality of measurement objects corresponding to the first BWP.

[0231] Optionally, when performing measurements, the terminal device may measure a measurement object corresponding to the first BWP, or may measure a measurement object corresponding to each BWP.

[0232] Optionally, the terminal device may not measure the second measurement object if the frequency of the reference signal associated with the intra-frequency measurement is the same as the frequency of the reference signal associated with the measurement object of the serving cell in the first BWP, and the frequency of the reference signal of the second measurement object is different from the frequency of the reference signal associated with the measurement object of the serving cell in the first BWP.

[0233] Step 303: The terminal device sends the measurement result to the network device, and in response, the network device receives the measurement result from the terminal device.

[0234] Based on the method shown in FIG. 3, when performing measurements, the terminal device can perform the measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP. The measurement object indicated by the measurement information transmitted from the network device to the terminal device can be one or more of information on measurement objects of the serving cell, information on intra-frequency measurements of neighboring cells, or information on inter-frequency measurements of neighboring cells. This can prevent all terminal devices from concentrating on the 20 MHz frequency domain resources of CD-SSB, thereby distributing the load on frequency domain resources. Because the terminal device can perform measurements based on reference signals associated with one or more measurement objects corresponding to the first BWP, if the first BWP does not include CD-SSB, the terminal device does not need to switch to the frequency domain resources where CD-SSB is located for measurements and then switch back to the first BWP. This can reduce the power consumption and complexity of the terminal device, improve the communication performance of the terminal device, and improve resource utilization of the communication system. Furthermore, by introducing measurements performed using measurement objects associated with NCD-SSB and specifying how the terminal device determines the measurement objects and reference signals, it is possible to avoid cases where measurement information needs to be frequently reconfigured.

[0235] For example, the measurement report information includes cell identity information. For example, the cell identity is a physical cell identity. For example, the cell identity information indicates a serving cell or a neighboring cell. For example, the cell identity information is 1 bit. For example, if the bit state of the cell identity information is 0, the cell identity information indicates that the report information is a serving cell. For example, if the bit state of the cell identity information is 1, the cell identity information indicates that the report information is a neighboring cell.

[0236] One cell or one carrier may have multiple SSBs at different frequencies, and two of the multiple SSBs at different frequencies may have the same cell ID (identity). Therefore, the measurement report information may further include characteristic information, which is used to identify or distinguish SSBs that have the same cell ID but different frequencies. For example, one cell or one carrier may have X SSBs at different frequencies. The types of the X SSBs at different frequencies may or may not be exactly the same. For example, one of the X SSBs at different frequencies is a CD-SSB, and the other X-1 SSBs are NCD-SSBs. The X SSBs at different frequencies are denoted as SSB1, SSB2, ..., and SSB(X-1), where X is a positive integer. SSBn and SSBm have the same cell ID. The measurement report information for SSBn reported by the UE may include cell identity information and characteristic information. The measurement report information for SSBm reported by the UE may also include cell identity information and characteristic information. The network device cannot determine whether the measurement report is associated with SSBn or SSBm based on the cell ID in the measurement report information. However, the network device can determine whether the measurement report is associated with SSBn or SSBm based on the cell ID and the characteristic information. In this way, this avoids the network device being unable to identify the source of the measurement report information, thereby improving the utilization of the measurement information and preventing the user equipment from reporting invalid measurement information.

[0237] In this embodiment of the present application, the characteristic information may be one or more of BWP information, reference signal information, and cell identification information. For example, the BWP information is at least one of BWP index information, BWP resource location information, BWP center frequency information, BWP subcarrier spacing information, BWP time information, and BWP frequency information. For example, the reference signal information is at least one of reference signal center frequency information, reference signal index information, reference signal resource location information, reference signal subcarrier spacing information, reference signal time information, and reference signal frequency information. For example, the reference signal may be an SSB. For example, the SSB type may be CD-SSB. For example, the SSB type may be NCD-SSB.

[0238] When the measurement report information only includes cell index information (e.g., physical cell index) and the measurement report result of the serving cell includes report information corresponding to multiple measurement reference signals or measurement objects, the report information needs to include reference signal information, BWP information, cell identity information, etc. corresponding to the reported measurement result. Thus, the network device can better determine the channel quality of the terminal device on frequency domain resources corresponding to different reference signals based on the information, and provide better service to the terminal device.

The terminal device 50 may include a transceiver module 501 and a processing module 502. For example, the terminal device 50 may be a terminal device, a chip used in a terminal device, or another composite device or component having the functionality of a terminal device.
