Abstract
Description
[0001] This application is a divisional application. The application number of the original application is 202111307503.X, and the original application date is November 5, 2021. The entire contents of the original application are incorporated into this application by reference. Technical Field
[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art
[0003] In a communication system, a network device may configure a bandwidth part (BWP) for a terminal device according to the bandwidth capability of the terminal device. For example, for a reduced capability user equipment (RedCap UE), the bandwidth of the BWP configured by the network device for the RedCap UE may not exceed 20 MHz.
[0004] Since the terminal device is mobile, the wireless channel conditions between the terminal device and the network device are constantly changing. After the terminal device accesses the service cell, it can perform channel measurement of the service cell in radio resource management (RRM) measurement, radio link monitoring (RLM) measurement or beam failure recovery (BFR) measurement according to the cell definition synchronization signal block (CD-SSB) of the current service cell.
[0005] If the activated BWP configured by the network device for the terminal device includes CD-SSB, all the terminal devices will be concentrated in the 20MHz frequency domain resource including CD-SSB, resulting in an unbalanced load on the frequency domain resources. If the activated BWP configured by the network device for the terminal device does not include CD-SSB, the terminal device needs to switch to the frequency domain resource where CD-SSB is located through frequency tuning for measurement, and then return to the activated BWP after measurement, resulting in increased power consumption and complexity of the terminal device, and may also cause communication interruption.
[0006] Therefore, how to improve the communication performance of terminal equipment and increase the resource utilization of the communication system has become a technical problem that needs to be solved urgently. Summary of the invention

[0113] Before describing the embodiments of the present application, the technical terms involved in the embodiments of the present application are described.
[0114] The fifth generation (5G) mobile communication system: Mobile communication technology has profoundly changed people's lives, but people's pursuit of higher performance mobile communication technology has never stopped. In order to cope with the explosive growth of mobile data traffic, massive mobile communication device connections, and the emergence of various new services and application scenarios in the future, the 5G communication system came into being. Among them, the International Telecommunication Union (ITU) has defined three major application scenarios for 5G communication systems and future mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable and low latency communications (URLLC), and massive machine type communications (mMTC).
[0115] Reduced capability user equipment (RedCap UE): The standard refers to mMTC service terminal equipment as RedCap UE, which can also be called low-complexity terminal equipment. This type of terminal equipment may be less complex than other terminal equipment in terms of bandwidth, power consumption, number of antennas, etc., such as narrower bandwidth, lower power consumption, fewer antennas, etc. This type of terminal equipment can also be called lightweight (NR light, NRL) terminal equipment.
[0116] Bandwidth part (BWP): 5G communication systems can support large bandwidths. For example, eMBB UE (or non-RedCap UE) can support a channel bandwidth of 100MHz. Taking into account energy saving and other requirements, the concept of BWP is introduced in the 5G standard. Network equipment can configure the bandwidth of BWP with resource blocks (RB) as the granularity. Because the bandwidth capability of RedCap UE is limited (such as the maximum channel bandwidth supported is small, such as 20MHz, while the maximum channel bandwidth supported by non-RedCap UE is 100MHz), the BWP bandwidth configured by the network equipment for RedCap UE cannot exceed the capability of RedCap UE, that is, it will not exceed 20MHz.
[0117] Since the UE is mobile and the wireless channel environment is constantly changing, the wireless channel conditions between the UE and the network equipment are constantly changing. Therefore, after the UE accesses a service cell, it is necessary to measure the channels of the service cell and the neighboring cells according to the network configuration and report them to the network equipment so that the network equipment can better allocate resources to the UE according to the channel conditions.
[0118] Radio resource management (RRM): can be used for mobility measurement, including measurement of serving cell reference signals and neighboring cell reference signals. The communication protocol stipulates that the network equipment can configure multiple measurement objects (MO) for the UE, and each MO can be associated with a reference signal for measurement. The reference signal of the serving cell can be a cell define synchronization signal block (CD-SSB). For a UE, a serving cell has only one CD-SSB, but can have several NCD-SSBs. If the bandwidth of the activated BWP (i.e., the BWP currently transmitting information) does not include CD-SSB, in order to measure the channel quality of the serving cell, the UE can only perform frequency tuning and switch to the frequency domain resources where the CD-SSB is located for measurement, and then return to the activated BWP after the measurement.
[0119] Radio link monitoring (RLM) measurement or beam failure recovery (BFR) measurement: only involves the measurement of the serving cell, that is, the measurement is performed using CD-SSB.
[0120] If the network is deployed in frequency range 1 (FR1), due to the limited bandwidth capability of the terminal device, although the bandwidth of the service cell or carrier can be 100MHz, the maximum bandwidth of the BWP configured for the terminal device can only be 20MHz. In this way, if the activated BWP configured by the network device for the terminal device includes CD-SSB, all terminal devices will be concentrated in the 20MHz frequency domain resources including CD-SSB, resulting in an unbalanced load on the frequency domain resources. If the activated BWP configured by the network device for the terminal device does not include CD-SSB, the terminal device needs to switch to the frequency domain resources where CD-SSB is located through frequency tuning for measurement, and then return to the activated BWP after the measurement, resulting in increased power consumption and complexity of the terminal device, and may also cause communication interruption.
[0121] Therefore, how to improve the communication performance of terminal equipment and increase the resource utilization of the communication system has become a technical problem that needs to be solved urgently.
[0122] In order to solve this problem, an embodiment of the present application provides a communication method, in which a terminal device can receive measurement information from a network device; wherein the measurement information is used to indicate one or more measurement objects, and the measurement information includes one or more of the following: information on the measurement object of the serving cell, information on the same-frequency measurement of the neighboring cell, and information on the different-frequency measurement of the neighboring cell; the terminal device performs one or more of the following measurements based on the reference signal associated with one or more measurement objects corresponding to the first BWP: wireless resource management RRM measurement, radio link monitoring RLM measurement, and beam failure recovery BFR measurement.
[0123] In an embodiment of the present application, when performing measurements, the terminal device can perform measurements based on the reference signals associated with one or more measurement objects corresponding to the first BWP. Since the measurement object indicated by the measurement information sent by the network device to the terminal device may be one or more of the information of the measurement object of the service cell, the information of the same-frequency measurement of the neighboring area, and the information of the different-frequency measurement of the neighboring area, it can avoid all terminal devices from being concentrated in the 20MHz frequency domain resources of the CD-SSB, thereby balancing the frequency domain resource load. The terminal device can perform measurements based on the reference signals associated with one or more measurement objects corresponding to the first BWP, thereby eliminating the need to switch to the frequency domain resources where the CD-SSB is located for measurement when the first BWP does not include the CD-SSB, and then switch to the first BWP, thereby reducing the power consumption and complexity of the terminal device, improving the communication performance of the terminal device, and improving the resource utilization of the communication system.
[0124] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0125] The communication method provided in the embodiment of the present application can be used in any communication system, which can be a third generation partnership project (3GPP) communication system, for example, an LTE communication system, or a fifth generation (5G) mobile communication system, a new radio (NR) communication system, a new radio vehicle to everything (NR V2X) system, and can also be applied to a system of LTE and 5G hybrid networking, or a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, the Internet of Things (IoT), and other next-generation communication systems, and can also be a non-3GPP communication system without limitation.

For example, it can be applied to one or more of the following communication scenarios: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), machine type communication (MTC), massive machine type communication (mMTC), D2D, V2X and IoT and other communication scenarios.
[0127] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present application are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0128] It should be understood that in the present application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist.

The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0153] Figure 3 A flow chart of a communication method provided in an embodiment of the present application, such as Figure 3 As shown, the method may include:
[0154] Step 301: The network device sends measurement information to the terminal device. Correspondingly, the terminal device receives the measurement information from the network device.
[0155] The measurement information may be used to indicate one or more measurement objects. The measurement information may include one or more of the following: information on the measurement object of the serving cell, information on the same-frequency measurement of the neighboring cell, and information on the different-frequency measurement of the neighboring cell.
[0156] Among them, the reference signal associated with each measurement object may include one or more of the following: CD-SSB, NCD-SSB, channel state information (channel-state information reference signal, CSI-RS). For example, the reference signal associated with the measurement object is a CD-SSB for serving cell measurement. For example, the reference signal associated with the measurement object is an NCD-SSB for serving cell measurement. For example, the reference signal associated with the measurement object is a CD-SSB for neighboring cell measurement. For example, the reference signal associated with the measurement object is an NCD-SSB for neighboring cell measurement.
[0157] For example, the measurement information may include identification information of a reference signal associated with the measurement object. For example, the identification information of the reference signal is used to indicate that the reference signal is one or more of the following: CD-SSB, NCD-SSB, CSI-RS.
[0158] When the measurement information is the information of co-frequency measurement of the neighboring cell or the information of heterofrequency measurement of the neighboring cell, it can be determined whether it is co-frequency measurement or heterofrequency measurement based on the frequency of the reference signal associated with the measurement object, without paying attention to whether the reference signal of the neighboring cell is CD-SSB or NCD-SSB.
[0159] For example, the period of NCD-SSB is greater than or equal to the period of CD-SSB. NCD-SSB is a reference signal for measurement. The period of NCD-SSB is configured by the network device. CD-SSB is a reference signal for measurement. The period of CD-SSB is configured by the network device. In this way, it is possible to avoid occupying too many processing resources for measuring NCD-SSB and increase the measurement burden of the terminal device. It is also possible to avoid occupying too many time and frequency resources of the network, resulting in a reduction in resources for data transmission.
[0160] For example, in order to reduce the complexity of the terminal device measurement, 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, there can only be one SSB in the first resource. By limiting the maximum number of NCD-SSBs included in the first resource, it is possible to avoid a heavy measurement burden on the terminal device due to a large number of NCD-SSBs.
[0161] For example, limit the maximum number N_max of NCD-SSBs that the network device can configure for the terminal device in the first resource. For example, limit the maximum number of NCD-SSBs supported by the terminal device in the first resource. For example, the network device configures NCD-SSB information for the terminal device through signaling. For example, the terminal device obtains the NCD-SSB information configured by the network device for the terminal device by receiving signaling. Among them, the NCD-SSB information includes one or more of the frequency information of the NCD-SSB, the number information of the NCD-SSB, and the maximum number information of the NCD-SSB. The NCD-SSB information can be associated with the BWP, or the NCD-SSB information can be associated with the carrier. Alternatively, limit the maximum number of NCD-SSBs supported by the network device.
[0162] For example, the maximum number of NCD-SSBs may be associated with the bandwidth of the first resource.
[0163] 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 BWP, and N_max=1.
[0164] 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 signal is a CD-SSB and / or an NCD-SSB. For example, Ns=1. For example, there is at most one complete SSB included in the BWP. The SSB is used for measurement. The SSB can be a CD-SSB or an NCD-SSB.
[0165] Optionally, the NCD-SSB used for measurement may not include a master information block (MIB), or the NCD-SSB used for measurement may be used for reinterpretation or for data transmission.
[0166] In one possible design, the frequency of the reference signal associated with the same-frequency measurement is the same as the frequency of the first reference signal. The frequency of the reference signal associated with the different-frequency measurement is different from the frequency of the first reference signal. In this way, the terminal device only needs to maintain the same-frequency measurement information on one frequency at the same time, saving power consumption and complexity of the terminal device.
[0167] The first reference signal may be a reference signal associated with a measurement object of a serving cell within the first BWP.
[0168] The terminal device is in a connected state, and the first BWP is an activated BWP. The terminal device is in a non-connected state, and the first BWP is a BWP where the terminal device resides.
[0169] In another possible design, the frequency of the reference signal associated with the same-frequency measurement is the same as the frequency of the second reference signal. The frequency of the reference signal associated with the different-frequency measurement is different from the frequency of the second reference signal. In this way, the terminal device simultaneously maintains all the same-frequency measurement information on the frequencies associated with all the measurement objects of the service cell, which can enable the terminal device and the network device to better obtain the channel quality of the terminal device on each part (BWP) of the frequency domain resources, and provide more comprehensive reference information for the network device to perform scheduling.
[0170] The second reference signal is a reference signal associated with a measurement object of a service cell of the terminal device. The second reference signal is a reference signal associated with any measurement object of a service cell of the terminal device. For example, if the service cell of the terminal device includes 5 measurement objects, any one of the reference signals associated with the 5 measurement objects is considered to be the second reference signal.
[0171] For example, the network device may configure one or more BWPs for the terminal device, and each BWP may correspond to one or more measurement objects.
[0172] The frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP may be the same as the frequency domain resources of the BWP, or the frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP are within the frequency domain resource range of the BWP. For example, the frequency domain resources are bandwidth.
[0173] For example, taking the case where 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 BWP configured by the network device for the terminal device includes BWP 1 and BWP 2, BWP 1 can correspond to the first measurement object, and BWP 2 can correspond to the second measurement object and the third measurement object.
[0174] It should be noted that the measurement objects corresponding to different BWPs may be the same or different.
[0175] For example, taking the case where the BWPs configured by the network device for the terminal device include BWP 1, BWP 2, and BWP 3, the measurement objects corresponding to BWP 1 and BWP 2 may be different, and the measurement objects corresponding to BWP 1 and BWP 3 may be the same.
[0176] In a first possible design, the network device carries the measurement information in the configuration information of the BWP and sends it to the terminal device, or it can also be described as the measurement information being carried in the configuration information of the BWP.
[0177] The network device may carry the measurement information corresponding to each BWP in the configuration information of each BWP (such as BWP-DownlinkDedicated) and send it to the terminal device.
[0178] For example, taking the example that the BWP configured by the network device for the terminal device includes BWP 1, BWP 2, and BWP 3, the configuration information of BWP 1 may include measurement information corresponding to BWP 1, and the measurement information corresponding to BWP 1 may be used to indicate one or more measurement objects corresponding to BWP 1; the configuration information of BWP 2 may include measurement information corresponding to BWP 2, and the measurement information corresponding to BWP 2 may be used to indicate one or more measurement objects corresponding to BWP 2; the configuration information of BWP 3 may include measurement information corresponding to BWP 3, and the measurement information corresponding to BWP 3 may be used to indicate one or more measurement objects corresponding to BWP 3.
[0179] The measurement information may include one or more of the following: measurement object information, measurement object list information, and SSB information.
[0180] 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 that can be used to indicate the 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 the following: frequency information of the SSB, the center frequency of the SSB, and the SSB index.
[0181] Optionally, when the measurement information includes measurement object list information, the measurement object list information also includes an index of the measurement object list.
[0182] Among them, for BWPs corresponding to the same measurement object, the index of the measurement object list included in the measurement information of the BWP may be the same; for BWPs corresponding to different measurement objects, the index of the measurement object list included in the measurement information of the BWP may be different.
[0183] For example, the BWP configured by the network device for the terminal device includes BWP 1, BWP 2, and BWP 3. Assuming that the measurement objects corresponding to BWP 1 and BWP 2 are different, and the measurement objects corresponding to BWP 1 and BWP 3 are the same, the indexes of the measurement object lists corresponding to BWP 1 and BWP 2 are different, and the indexes of the measurement object lists corresponding to BWP 1 and BWP 3 are the same.
[0184] Alternatively, the indexes of the measurement object lists included in the configuration information of different BWPs may be different.
[0185] For example, the BWP configured by the network device for the terminal device includes BWP 1, BWP 2, and BWP 3. The index of the measurement object list corresponding to BWP 1 may be index 1, the index of the measurement object list corresponding to BWP 2 may be index 2, and the index of the measurement object list corresponding to BWP3 may be index 3.
[0186] It should be noted that when the configuration information of the BWP configured by the network device for the terminal device includes the measurement information corresponding to the BWP, when the BWP is the first BWP, the terminal device can perform measurements based on the measurement information corresponding to the first BWP. When the configuration information of the BWP configured by the network device for the terminal device does not include the 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 (that is, as described above, when the activated BWP includes the CD-SSB of the serving cell, the measurement is performed based on the CD-SSB of the serving cell, and when the activated BWP does not include the CD-SSB of the serving cell, the terminal device switches to the CD-SSB of the serving cell for measurement, and then switches back to the activated BWP).
[0187] For example, the measurement information may include one or more of the following: identification information of a serving cell of the measurement object, and identification information of a neighboring cell of the measurement object.
[0188] The network device indicates the identification information of the service cell of the measurement object in the measurement information, or the network device indicates the identification information of the neighboring area of the measurement object in the measurement information, so that the terminal device can determine whether the current measurement object is the measurement object of the service cell or the measurement object of the neighboring area based on the identification information of the cell of the measurement object.
[0189] In a second possible design, the network device may carry the measurement information in the configuration information of the serving cell (such as ServingCellConfig) and send it to the terminal device, or it may also be described as the measurement information being carried in the configuration information of the serving cell.
[0190] The measurement information may include one or more of the following: measurement object information, one or more measurement object list information, and SSB information.
[0191] 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 that can be used to indicate the 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 the following: frequency information of the SSB, and an SSB index.
[0192] Exemplarily, the network device may be configured with one or more measurement objects, and indicate the one or more measurement objects configured by the network device through a measurement object list.
[0193] In this exemplary embodiment, the terminal device can determine the measurement object corresponding to the BWP through the resource range of the BWP.
[0194] For example, the resource scope is bandwidth.
[0195] The frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP may be the same as the frequency domain resources of the BWP, or the frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP are within the frequency domain resource range of the BWP.
[0196] In another example, the network device may configure measurement objects corresponding to each BWP for each BWP, and indicate the measurement objects configured by the network device for the multiple BWPs through multiple measurement object lists.
[0197] In this exemplary embodiment, the terminal device can determine the measurement object corresponding to the BWP through the resource range of the BWP.
[0198] The frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP may be the same as the frequency domain resources of the BWP, or the frequency domain resources of the reference signal associated with the measurement object corresponding to each BWP are within the frequency domain resource range of the BWP.
[0199] Alternatively, when the measurement object list information also includes an index of the measurement object list, the terminal device may also determine the measurement object list corresponding to the BWP through the index corresponding to the BWP, thereby determining the measurement object corresponding to the BWP.
[0200] Among them, for BWPs corresponding to the same measurement object, the indexes of the measurement object lists corresponding to the BWPs may be the same; for BWPs corresponding to different measurement objects, the indexes of the measurement object lists corresponding to the BWPs are different.
[0201] For example, taking the BWP configured by the network device for the terminal device including BWP 1, BWP 2, and BWP 3 as an example, assuming that the measurement objects corresponding to BWP 1 and BWP 2 are different, and the measurement objects corresponding to BWP 1 and BWP 3 are the same, then the indexes of the measurement object lists corresponding to BWP 1 and BWP 2 are different, and the indexes of the measurement object lists corresponding to BWP 1 and BWP 3 are the same.
[0202] Alternatively, the indexes of the measurement object lists included in the configuration information of different BWPs may be different.
[0203] For example, taking the BWP configured by the network device for the terminal device including BWP 1, BWP 2, and BWP 3 as an example, the index of the measurement object list corresponding to BWP 1 can be index 1, the index of the measurement object list corresponding to BWP 2 can be index 2, and the index of the measurement object list corresponding to BWP3 can be index 3.
[0204] Exemplarily, the number of measurement objects indicated by the measurement information may be less than or equal to the number of BWPs configured by the network device for the terminal device. Or, the number of reference signals associated with the measurement objects indicated by the measurement information may be less than or equal to the number of BWPs configured by the network device for the terminal device. For example, the reference signal is one or more of the following: NCD-SSB, CD-SSB, CSI-RS.
[0205] For example, Figure 4As shown, taking the measurement information included in the configuration information of the serving cell as an example to indicate 5 measurement objects, assuming that the 5 measurement objects are respectively associated with 5 SSBs, and these 5 SSBs can be CD-SSBs or NCD-SSBs. These 5 SSBs can correspond to different BWPs, such as NCD-SSB1 corresponds to BWP 1, NCD-SSB2 corresponds to BWP 2, CD-SSB corresponds to BWP3, NCD-SSB3 corresponds to BWP 4, and NCD-SSB4 corresponds to BWP 5.
[0206] Optionally, the network device may send a first signaling to the terminal device, and the terminal device may perform measurements based on the first signaling.
[0207] The first signaling may be used to instruct to perform measurement according to a reference signal associated with one or more measurement objects corresponding to the first BWP.
[0208] Exemplarily, the first signaling may be downlink control information (DCI) or media access control control unit (MAC CE) signaling. The network device may use dynamic signaling to indicate the measurement object information so as to perform measurement configuration more flexibly according to the network status.
[0209] Among them, DCI can be used to indicate BWP switching.
[0210] The network device may send a first signaling to dynamically instruct the terminal device to perform measurements according to one or more measurement objects corresponding to the first BWP. Alternatively, the network device may send a first signaling to dynamically instruct the terminal device to perform measurements according to a reference signal 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.
[0211] It should be noted that when a BWP corresponds to multiple measurement objects, the terminal device can maintain multiple sets of measurements in one BWP. When a BWP corresponds to one measurement object, the terminal device can maintain one set of measurements in one BWP. When a BWP corresponds to one measurement object, it can avoid the terminal device maintaining multiple sets of measurements in one BWP, and avoid the terminal device occupying more resources.
[0212] Optionally, the first indication information sent by the terminal device is received. The network device receives the first indication information sent by the terminal device, so that the network device can better configure appropriate measurement resources for the terminal device according to its capability.
[0213] For example, the first indication information can be used to indicate whether the terminal device supports RRM measurement, RLM measurement, beam-related measurement or BFR measurement according to NCD-SSB.
[0214] For example, the first indication information can be used to indicate one or more of the following:
[0215] The terminal device supports that the first resource includes NCD-SSB;
[0216] The terminal device does not support NCD-SSB included in the first resource;
[0217] The terminal device supports one or more of the following according to NCD-SSB: RRM measurement, RLM measurement, beam correlation measurement or BFR measurement;
[0218] The terminal device does not support one or more of the following according to NCD-SSB: RRM measurement, RLM measurement, beam correlation measurement or BFR measurement;
[0219] The terminal device supports RRM measurement of the serving cell according to NCD-SSB;
[0220] The terminal device does not support RRM measurements of the serving cell according to NCD-SSB;
[0221] The terminal device supports RRM measurement of non-serving cells (or neighboring cells) according to NCD-SSB;
[0222] The terminal device does not support RRM measurements of non-serving cells (or neighboring cells) according to NCD-SSB;
[0223] The terminal equipment supports NCD-SSB and CD-SSB which are quasi-co-site QCL;
[0224] The terminal equipment supports NCD-SSB and CD-SSB is non-quasi-co-located;
[0225] The PCI supported by the terminal device for NCD-SSB is different from that for CD-SSB;
[0226] The terminal device supports the same PCI of NCD-SSB and PCI of CD-SSB;
[0227] The terminal device supports CD-SSB measurement by measuring the gap;
[0228] The terminal device does not support CD-SSB measurement by measuring the gap;
[0229] The period of NCD-SSB supported by the terminal device is different from that of CD-SSB;
[0230] The period of NCD-SSB supported by the terminal equipment is the same as that of CD-SSB;
[0231] The terminal device supports different transmit powers for NCD-SSB and CD-SSB;
[0232] The terminal device supports the same transmit power for NCD-SSB as for CD-SSB;
[0233] The number of NCD-SSBs supported by the terminal device within one carrier;
[0234] The number of NCD-SSBs that the terminal device can measure within one carrier;
[0235] The number of NCD-SSBs supported by the terminal device within one BWP;
[0236] The number of NCD-SSBs that a terminal device can measure within one BWP.
[0237] }
[0238] For example, the first resource is a BWP or a carrier.
[0239] For example, the first indication information is used to indicate one or more of the following: the terminal device supports that SSB and / or CORESET#0 are not included in the first resource; the terminal device supports that NCD-SSB is included in the first resource.
[0240] For example, the first indication information is 1 bit. The bit state of the first indication information is 0, and the first indication information is used to indicate that the terminal device supports that SSB and / or CORESET#0 are not included in the first resource. The bit state of the first indication information is 1, and the first indication information indicates that the terminal device supports that NCD-SSB is included in the first resource. Alternatively, the bit state of the first indication information is 1, and the first indication information indicates that the terminal device supports that SSB and / or CORESET#0 are not included in the first resource. Alternatively, the bit state of the first indication information is 0, and the first indication information indicates that the terminal device supports that NCD-SSB is included in the first resource.
[0241] If the terminal device supports RRM measurement, RLM measurement, beam-related measurement or BFR measurement based on NCD-SSB, the network device may configure the measurement object associated with NCD-SSB when configuring the measurement object for the terminal device.
[0242] Optionally, the network device may also receive second indication information sent by the terminal device; wherein the second indication information may be used to indicate the maximum number of frequency points supported by the terminal device. For example, the frequency point is the frequency or center frequency of the measured reference signal. For example, the measurement is the same-frequency measurement and / or the different-frequency measurement.
[0243] Exemplarily, the maximum value may be greater than or equal to 8, for example, the maximum value may be 8, 10, 12, 14, or 16, etc.
[0244] It should be noted that the sum of the number of frequency points corresponding to the same-frequency measurement and different-frequency measurement supported by the terminal device can be greater than 8.
[0245] The number of frequency points supported by the terminal device in the first measurement period may be less than or equal to 8. The frequency points supported by the terminal device in different first measurement periods may be the same or different. The first measurement period is the minimum value of the measurement periods corresponding to one or more measurement objects.
[0246] For example, taking the first measurement period including the first measurement period 1, the first measurement period 2, and the first measurement period 3 as an example, the frequency point supported by the terminal device in the first measurement period 1 may be the same as the frequency point supported in the first measurement period 2, and the frequency point supported by the terminal device in the first measurement period 1 may be different from the frequency point supported in the first measurement period 3.
[0247] By increasing the total number of frequency points corresponding to the same-frequency measurement and different-frequency measurement supported by the terminal equipment, it is possible to avoid affecting the network service quality due to the limited number of measurements after the introduction of NCD-SSB, or to avoid excessive measurement burden on the terminal equipment.
[0248] Optionally, when the network device indicates the SSB to the terminal device, considering that CD-SSB and NCD-SSB may have differences in filtering and reporting of measurements, the network device may indicate to the terminal device whether the SSB is CD-SSB or NCD-SSB.
[0249] The network device may indicate to the terminal device whether the SSB is CD-SSB or NCD-SSB through configuration information. For example, the configuration information is one or more of the following: RRC configuration information, serving cell configuration information, and BWP configuration information.
[0250] Exemplarily, the first parameter of NCD-SSB is configured the same as the first parameter of CD-SSB. For example, the first parameter is at least one of the following: subcarrier spacing, transmit power, reference signal index. For example, the transmit power is at least one of the following: primary synchronization signal transmit power, secondary synchronization signal transmit power. For example, the reference signal index is an index bitmap. For example, the reference signal index is used to indicate the time domain information of the reference signal sent by the network device. For example, the index includes 8 bits, and the bitmap is 10001000, indicating that the 0th and 4th reference signals are sent 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.
[0251] Exemplarily, the reference signal for neighboring cell measurement includes at least CD-SSB, or the reference signal for neighboring cell measurement can only be CD-SSB. Because when selecting a neighboring cell, if there are multiple reference signals and the measurement reference values are different, the determined neighboring cell channel quality may be different, which may cause the selected neighboring cell to be not the optimal neighboring cell. Therefore, try to select CD-SSB as the reference signal for the neighboring cell or include at least CD-SSB in the neighboring cell reference signal.
[0252] Step 302: The terminal device performs measurement according to a reference signal associated with one or more measurement objects corresponding to the first BWP.
[0253] Optionally, the terminal device is in a connected state, and the first BWP may be an activated BWP. Alternatively, the terminal device is in a non-connected state, and the first BWP may be a resident BWP of the terminal device.
[0254] The measurement may include one or more of the following measurements: RRM measurement, RLM measurement, BFR measurement, beam measurement, and beam failure detection BFD measurement.
[0255] It should be noted that when the measurement is an RRM measurement, the measurement information may be the measurement information described in the above step 301. When 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 in the downlink frequency information (FrequencyInfoDL).
[0256] Among them, 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 according to 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 according to the frequency domain resources of the first BWP.
[0257] Exemplarily, the frequency domain resources of the reference signal associated with the measurement object corresponding to the first BWP are the same as the frequency domain resources of the first BWP; or, the frequency domain resources of the reference signal associated with the measurement object corresponding to the first BWP are within the frequency domain resource range of the first BWP.
[0258] Optionally, when the first BWP corresponds to multiple measurement objects, the terminal device may select a measurement object from the multiple measurement objects corresponding to the first BWP for measurement, which may reduce power consumption of the terminal device.
[0259] Exemplarily, the terminal device may select a predefined measurement object from multiple measurement objects corresponding to the first BWP for measurement. Alternatively, the terminal device may also select a CD-SSB-associated measurement object from multiple measurement objects corresponding to the first BWP for measurement. Alternatively, the terminal device may also select a measurement object with the smallest index from multiple measurement objects corresponding to the first BWP for measurement. Alternatively, the terminal device may also select a measurement object corresponding to a reference signal whose frequency is closest to the center frequency of the first BWP from multiple measurement objects corresponding to the first BWP for measurement.
[0260] Optionally, when performing measurement, the terminal device may measure the measurement object corresponding to the first BWP, or may measure the measurement objects corresponding to each BWP.
[0261] Optionally, when the frequency of the reference signal associated with the same-frequency measurement is the same as the frequency of the reference signal associated with the measurement object of the service cell in the first BWP, the terminal device may not measure the second measurement object; wherein 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 service cell in the first BWP.
[0262] Step 303: The terminal device sends the measurement result to the network device, and correspondingly, the network device receives the measurement result from the terminal device.
[0263] Based on the above Figure 3 According to the method shown, when the terminal device is measuring, it can measure according to the reference signal associated with one or more measurement objects corresponding to the first BWP. Since the measurement object indicated by the measurement information sent by the network device to the terminal device can be one or more of the information of the measurement object of the service cell, the information of the same-frequency measurement of the neighboring area, and the information of the different-frequency measurement of the neighboring area, it can avoid all the terminal devices from being concentrated in the 20MHz frequency domain resource of CD-SSB, thereby balancing the frequency domain resource load. The terminal device can measure according to the reference signal associated with one or more measurement objects corresponding to the first BWP, so that when the first BWP does not include CD-SSB, it is not necessary to switch to the frequency domain resource where CD-SSB is located for measurement, and then switch to the first BWP, thereby reducing the power consumption and complexity of the terminal device, improving the communication performance of the terminal device, and improving the resource utilization of the communication system. In addition, the embodiment of the present application introduces the measurement of the measurement object associated with NCD-SSB, and stipulates how the terminal device determines the measurement object and the reference signal, which can avoid the need to frequently reconfigure the measurement information.
[0264] Exemplarily, the measurement report information includes cell identification information. For example, the cell identification is a physical cell identification. For example, the cell identification information is used to indicate a serving cell or a neighboring cell. For example, the cell identification information is 1 bit. For example, the bit state of the cell identification information is 0, and the cell identification information indicates that the reported information is a serving cell. For example, the bit state of the cell identification information is 1, and the cell identification information indicates that the reported information is a neighboring cell.
[0265] When there are multiple SSBs with different frequencies in a cell or a carrier, and there may be two SSBs with different frequencies among these multiple SSBs with different frequencies that have the same cell identifier. For this reason, the measurement report information may also include feature information, which is used to identify or distinguish SSBs with different frequencies that have the same cell identifier. For example, there are X SSBs with different frequencies in a cell or a carrier. The types of the X SSBs with different frequencies may be exactly the same or not exactly the same. For example, one SSB among the X SSBs with different frequencies is a CD-SSB, and the other X-1 SSBs are NCD-SSBs. These X SSBs with different frequencies are recorded as: SSB1, SSB2,…, SSB(X-1). Where X is a positive integer. SSBn and SSBm have the same cell identifier. The UE may include the cell identifier and feature information in the measurement report information of SSBn. The UE may also include the cell identifier and feature information in the measurement report information of SSBm. The network device cannot determine whether the measurement report is associated with SSBn or SSBm based on the cell identifier 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 identifier and characteristic information. This avoids the situation where the network device cannot identify the source of the measurement report information, improves the utilization of the measurement information, and avoids invalid measurement information reporting by the user equipment.
[0266] In an embodiment of the present application, the characteristic information may be one or more of the following: BWP information, reference signal information, and cell identification information. For example, the BWP information is at least one of the following: BWP index information, BWP resource location information, BWP center frequency information, subcarrier spacing information on BWP, BWP time information, and BWP frequency information. For example, the reference signal information is at least one of the following: center frequency information of the reference signal, index information of the reference signal, reference signal resource location information, subcarrier spacing information of the reference signal, reference signal time information, and reference signal frequency information. For example, the reference signal may be an SSB. For example, the type of SSB may be CD-SSB. For example, the type of SSB may be NCD-SSB.
[0267] If the measurement report information only includes cell index information (such as physical cell index), and the measurement report result of the serving cell includes report information corresponding to multiple measurement reference signals or measurement objects, it is necessary to include reference signal information, BWP information, cell identification information, etc. corresponding to the reported measurement result in the report information, so that the network device can better determine the channel quality of the terminal device on the frequency domain resources corresponding to different reference signals based on this information, thereby better providing services for the terminal device.
[0268] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between devices. It is understandable that, in order to realize the above functions, each device includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present application.
[0269] The embodiment of the present application can divide the functional modules of each device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
[0270] In the case of dividing each functional module into corresponding functional modules, Figure 5A terminal device is shown, and the terminal device 50 may include a transceiver module 501 and a processing module 502.

[0276] In the case of dividing each functional module into corresponding functional modules, Figure 6 A network device is shown, and the network device 60 may include a processing module 601 and a transceiver module 602. Exemplarily, the network device 60 may be a network device, or a chip applied to the network device or other combined devices, components, etc. having the above network device functions.
