AI Technical Summary
When deploying artificial intelligence/machine learning models on the network device side, the terminal device needs to provide a large number of measurement results to the network device. The existing method leads to large signaling overhead, and the PUCCH capacity is limited and unstable.

[0043] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).
[0044] Radio resource management (RRM) measurements
[0045] In the cellular communication system of the Third Generation Partnership Project (3GPP), terminal devices can switch radio resource control (RRC) connections between different cells. The management associated with switching RRC connections by terminal devices is called mobility management. Mobility management is a core process in the control plane process of the standard specification. To perform mobility management on terminal devices, the terminal device needs to measure the strength or quality of the radio signals in the current serving cell and neighboring cells. These measurements are called RRM measurements.
[0046] In some embodiments, a terminal device may perform RRM measurements based on a measurement task. For example, a terminal device may perform RRM measurements based on a measurement task instructed by a network device. As an implementation, when a network device configures a measurement task for a terminal device, the measurement task may include a measurement object (MeasObjectNR), a reporting configuration (MeasConfig), and a measurement identifier (measID).
[0047] The measurement object may include the measured frequency and a description of the reference signal corresponding to the measurement. In some embodiments, if the frequency to be measured is the same as the center frequency of the frequency of the terminal device's current serving cell and has the same subcarrier spacing, then this measurement may be called an intra-frequency measurement; otherwise, it is called an inter-frequency measurement.
[0048] The reporting configuration may include configuration information related to the measurement. For example, the reporting configuration may include the type of measurement reporting and various configuration parameters corresponding to each reporting type.
[0049] There can be many types of measurement reports, such as periodic reporting, reporting based on measurement events, and continuing periodic reporting after measurement event reporting. As an example, in a second-generation communication system, measurement reports are always reported according to a certain period, that is, the terminal device periodically reports measurement reports to the network device. As another example, in a third-generation communication system (such as a WCDMA system), a fourth-generation communication system (LTE system), and a fifth-generation communication system (NR system), measurement reports can be reported in any of the three ways mentioned above.
[0050] A measurement identifier can be used to identify a measurement task. In other words, a measurement task can associate a measurement object with a measurement configuration. This measurement task is indicated by a measurement identifier.
[0051] After performing RRM measurements based on a measurement task, the terminal device can report the measurement details to the network device in the form of a measurement report. This allows the network device to make relevant decisions based on the reported contents, such as handover decisions and secondary cell group (SCG) changes. The following is a brief introduction to measurement reports.
[0052] Regardless of the type of measurement reporting (e.g., periodic reporting) adopted by the terminal device to report the measurement report, the measurement report may include specific measurement events and / or measurement results. As an example, the measurement report may include the signal strength of the cell, such as the reference signal receiving power (RSRP) of the cell, where the RSRP of the cell may be measured in dBm. As another example, the measurement report may include the signal quality of the cell, such as the reference signal receiving quality (RSRQ) of the cell, where the RSRQ of the cell may be measured in db.
[0053] In the measurement report, the cells reported by the terminal device may include the current serving cell and / or neighboring cells. For example, the terminal device may report the signal strength and signal quality of the current serving cell. Alternatively, the terminal device may report the signal strength and signal quality of the current serving cell and neighboring cells.
[0054] The measurement report may include multiple measurement objects, for example, the measurement object may be the same frequency, different frequency, or different communication system frequency.
[0055] As mentioned above, the measurement report may include a measurement event. The triggering of the measurement event is described below. In some embodiments, the triggering of the measurement event may include basic elements such as measurement results, comparison parameters, and timers. These basic elements are described below.
[0056] The measurement results may be, for example, measurement results of the serving cell and / or neighboring cells. For example, the measurement results may be signal strength of the serving cell and / or neighboring cells. Alternatively, the measurement results may be signal quality of the serving cell and / or neighboring cells. In standard protocols, generally, a larger numerical value of a dimension of a measurement result indicates a higher signal strength or quality.
[0057] The comparison parameters corresponding to a measurement event may include one or more parameters. For example, the comparison parameters corresponding to a measurement event may include one or more of the following parameters: a threshold, a hysteresis value, an offset value, etc. The comparison parameters corresponding to the measurement event may be compared with the measurement results of the cell to determine whether the entry and / or exit conditions of the measurement event are met. As a possible implementation, the comparison parameters may be compared absolutely with the measurement results of the cell. Absolute comparison may refer to comparing the measurement results of a cell with a threshold. In this case, if the measurement result of the cell is greater than the sum of the threshold and the hysteresis value, the cell is considered to meet the entry conditions for the measurement event; if the measurement result of the cell is less than the difference between the threshold and the hysteresis value, the cell is considered to meet the exit conditions for the measurement event. As another possible implementation, the comparison parameters may be compared relatively with the measurement results of the cell. Relative comparison may refer to comparing the measurement results of neighboring cells with the measurement results of the serving cell. In some embodiments, before comparing the measurement results of neighboring cells with the measurement results of the serving cell, each cell needs to add its own relevant offset value. For the serving cell, the offset value related to the corresponding event needs to be added. In addition, the hysteresis value needs to be considered when comparing the measurement results of neighboring cells with the measurement results of the serving cell. Taking event A3 as an example, the following provides an example of comparing the measurement results of the neighboring cell and the measurement results of the serving cell.
[0058] The entry condition corresponding to event A3 can be expressed as: n +of n >M s +of s +Hys+off_event
[0059] The exit condition corresponding to event A3 can be expressed as: n +of n <M s +of s -Hys+off_event
[0060] Among them, M n Indicates the measurement results of neighboring cells, of n Indicates the offset value of the neighboring cell, M s Indicates the measurement result of the serving cell, s It represents the offset value of the serving cell, Hys represents the hysteresis value, and off_event represents the offset value related to the corresponding event.
[0061] A timer can be used to indicate the robustness of a measurement result. For example, the timer can be a time to trigger (TTT) timer. In some embodiments, when a cell meets the entry conditions of a measurement event, a TTT timer is started. When the TTT timer times out, if the cell continues to meet the entry conditions of the measurement event, it can be considered that the cell has triggered the measurement event. As shown in Figure 2, the target cell meets the entry conditions of the measurement event at time T0, at which time the TTT timer is started, and the timing duration of the TTT timer is t. If the target cell continues to meet the entry conditions of the measurement event during the time period from T0 to T0+t, it can be considered that the target cell has triggered the measurement event.
[0062] Currently, the measurement results used to determine measurement events are filtered at Layer 3, while the initial measurement results within the terminal device are physical layer measurements of a single beam. The following, combined with Figure 3, explains how the terminal device obtains single-beam measurement results and triggers measurement events.
[0063] Figure 3 illustrates how a terminal device performs intra-frequency and inter-frequency measurements, from sampling measurements based on beams at Layer 1 to determining measurement events based on network configuration parameters. First, several reference points shown in Figure 3 are introduced.
[0064] Reference point A is where the terminal device performs physical layer measurement sampling. In some embodiments, the terminal device can perform physical layer measurement sampling according to the granularity of the beam.
[0065] Reference point A1 is where the terminal device performs layer 1 filtering on the measured beam measurement results. It should be noted that the beam measurement results after layer 1 filtering must meet the performance requirements specified in relevant specifications (such as 3GPP specifications). Generally speaking, the protocol can specify the length of the measurement period under a specific RRC configuration. During the measurement period, the terminal device must perform at least one sampling. In some embodiments, the specific number of sampling times of the terminal device in a measurement period is specified. For example, in the test case, the terminal device can perform 4-5 oversamplings in a measurement period.
[0066] Reference point B combines the beam measurement results within a certain cell obtained from A1 to synthesize the measurement results at the layer 1 cell level.
[0067] Reference point C is to perform layer 3 filtering on the layer 1 cell-level measurement result of a certain cell to obtain the layer 3 cell-level measurement result of the cell.
[0068] Reference point D is used to determine whether a specific measurement event exists by judging the measurement results of the serving cell and / or neighboring cells according to certain decision conditions (e.g., decision conditions configured by the network). For example, it determines whether the measurement result of the neighboring cell is higher than that of the serving cell by an offset value (i.e., event A3).
[0069] For the related descriptions of other reference points in Figure 3 (such as the definitions of reference point E and reference point F), please refer to 3GPP protocol TS38.331 and will not be repeated here.
[0070] As shown in Figure 3, after the terminal device obtains the beam measurement results at layer 1, it performs a consolidation process to perform a weighted average of the qualified beam measurement results in the cell to obtain the cell measurement results at layer 1. The cell measurement results at layer 1 are then filtered at layer 3 to obtain the measurement results used for measurement event determination. Furthermore, Figure 3 shows that a certain period of time passes from the time a measurement event is entered before a determination result is obtained.
[0071] After the terminal device performs the RRM measurement, the type of measurement result sent to the network device can be a layer 1 beam measurement result, a layer 1 cell measurement result, or a layer 3 beam measurement result, which can be determined according to the measurement configuration sent by the network device. For example, the network device can indicate a type of measurement result in the measurement configuration (for example, a layer 1 beam measurement result), and the terminal device can report according to the instruction of the network device. Alternatively, the network device can indicate a group of measurement result types in the measurement configuration (for example, a layer 1 beam measurement result, a layer 1 cell measurement result), and the terminal device can choose a type of measurement result to report, and indicate the type of measurement result reported in the measurement report. For example, the terminal device chooses to report a layer 1 beam measurement result, and indicates in the measurement report that the reported measurement result is a layer 1 beam measurement result.
[0072] When the type of measurement result reported by the terminal device is different, the carrying method of the measurement report will also be different. For example, when the terminal device reports the measurement result of layer 3, it can be reported through the RRC message of the higher layer. Alternatively, when the terminal device reports the measurement result of layer 1 (for example, the beam measurement result of layer 1 and / or the cell measurement result of layer 1), it can be reported through the uplink control information (UCI) of the physical layer.
[0073] The UCI of the measurement result of the bearer layer 1 can be sent in different ways. For example, the UCI can be sent through PUCCH, or the UCI can be sent through PUSCH. Currently, when the terminal device sends the UCI through PUCCH, the PUCCH is semi-persistent or periodically sent. When the terminal device sends the UCI through PUSCH, the PUSCH is non-periodic or semi-persistent. In some embodiments, the semi-static transmission method can also be understood as a periodic reporting method that requires activation by a network device, for example, a periodic reporting method that requires activation by a network device through a medium access control control element (MAC CE).
[0074] It should be noted that the reporting of layer 1 measurement results by terminal devices through UCI was proposed when the low layer trigger mobility (LTM) handover project in release 18 (Rel 18) was standardized. In the LTM handover scenario, after the terminal device receives a list of handover candidate cells, it can measure the reference signals on these candidate cells according to the configuration of the network device and report the measurement results of these reference signals to the network device through UCI. Among them, the measurement results of these reference signals are layer 1 measurement results.
[0075] It should be understood that the UCI required by the existing physical layer process is limited to the serving cell, so the amount of information that UCI can carry is limited. The reason why LTM switching uses UCI to report measurement results is that the switching candidate cell list sent by the network device to the terminal device is itself a relatively short list, that is, the number of cells in the switching candidate cell list is relatively small. One reason why this switching candidate cell list is relatively short is that the premise that the network device sends the switching candidate cell list to the terminal device is usually that the network device has received the measurement report sent by the terminal device containing the layer 3 measurement results. In other words, the network device has performed a round of screening based on the measurement report provided by the terminal device. Another reason why this list is relatively short is that the main purpose of LTM switching is to shorten the switching delay, so the terminal device needs to complete the measurement and reporting quickly. Therefore, in the LTM switching scenario, the amount of UCI information that the terminal device needs to report is relatively small.
[0076] AI / ML models
[0077] In Rel 18, 3GPP studied whether AI / ML models (or AI / ML algorithms) can help improve the performance of the physical layer. The relevant research results are recorded in the technical report TR38.843. In addition to recording the evaluation methods and results related to AI / ML models, this technical report also records the steps and content for managing AI / ML on the network side or the terminal device side, or both sides. These related contents constitute the life cycle management (LCM) content in this technical report. It should be noted that LCM is a relatively broad term, and its content includes data collection, model training, function / model identification, model transmission, model reasoning, function / model selection, activation, deactivation, replacement and fallback, function / model monitoring, model update, terminal device capability reporting, etc.
[0078] In some embodiments, the AI / ML model can be used for beam measurement prediction for beam management. As an example, the AI / ML model can be applied to beam prediction in the spatial domain, that is, the best beam in the full set of beams (for example, the beam with the strongest wireless signal) can be predicted by measuring a subset of beams in a set and utilizing the spatial correlation between the beams. For example, the AI / ML model can be used to predict a beam or a pair of beams with the strongest wireless signal in the full set of beams, which can be used for downlink transmission and reception. As another example, the AI / ML model can be applied to beam prediction in the time domain, that is, the measurement results of the beam in the current time slot can be predicted based on the measurement results of the historically measured beams and / or the predicted beams and utilizing the temporal correlation of the beams. The AI / ML model's beam prediction in the spatial and time domains is not only technically feasible, but also provides a higher performance improvement.
[0079] In some embodiments, the technology of using AI / ML models to predict beam measurements can be applied to other scenarios, for example, it can be applied to RRM measurements so that the network can make further switching decisions as early as possible based on the predicted RRM measurement results.
[0080] As a possible implementation, when applying AI / ML models in RRM measurement scenarios, the AI / ML models can be deployed on the terminal device side, on the network device side, or on both the terminal device and the network device side. If the AI / ML model is deployed on the network device side, the AI / ML model running on the network device side may require the terminal device to provide a large amount of auxiliary information, especially auxiliary information related to wireless signal measurements, in order for the AI / ML model on the network device side to operate. In other words, in RRM measurement scenarios, if the AI / ML model is to be deployed on the network device side, the terminal device may be required to provide a large amount of measurement results.
[0081] This is because, if the AI / ML model is deployed on the network equipment side, for a single terminal device, on the one hand, the network equipment needs to collect measurement reports of the terminal device's current serving cell and measurement reports of all possible neighboring cells, that is, the number of cells reported by the terminal device is greater; on the other hand, the network equipment needs to continuously obtain measurement results provided by the terminal device in order to make reasonable predictions in the time domain, that is, the terminal device needs to provide measurement results more frequently. These two reasons will cause the terminal device to provide a large number of measurement results to the network device.
[0082] When a terminal device needs to send a large number of measurement results to a network device, the transmission of a large number of measurement results will result in a large signaling overhead.
[0083] To address the above issues, this application proposes two embodiments: Embodiment 1 aims to reduce signaling overhead by transmitting measurement results through a new reporting approach; and Embodiment 2 aims to reduce signaling overhead by updating the content of the reported measurement results.
[0084] The embodiments of the present application can be applied to scenarios where RRM measurements are performed using AI / ML models, but the present application is not limited thereto. The present application can also be applied to other scenarios where a large number of measurement results need to be sent to a network device.
[0085] It should be noted that the "physical layer" mentioned in the embodiments of this application can be replaced with "layer 1", or in other words, the "physical layer" and "layer 1" mentioned in the embodiments of this application can be replaced with each other. For example, "physical layer measurement results" can be equivalently replaced with "layer 1 measurement results", etc., and the embodiments of this application do not distinguish between them.
[0086] It should also be noted that the "RRC layer" mentioned in the embodiments of the present application can be replaced with "Layer 3", or in other words, the "RRC layer" and "Layer 3" mentioned in the embodiments of the present application can be replaced with each other. For example, "RRC layer measurement results" can be equivalently replaced with "Layer 3 measurement results", etc., and the embodiments of the present application do not distinguish between them.
[0087] In some embodiments, the “measurement result of layer 1 ” mentioned in the embodiments of the present application means that the measurement result is obtained by measuring on layer 1 , and the measurement result is used to indicate the characteristics or information of layer 1 .
[0088] The layer 1 measurement results mentioned in the embodiments of the present application may be any measurement results for layer 1, and the embodiments of the present application are not limited thereto. For example, the layer 1 measurement results may include one or more of the following: layer 1 beam measurement results, layer 1 cell measurement results.
[0089] In some embodiments, if the measurement result sent by the terminal device to the network device is a layer 1 cell measurement result, then the layer 1 cell measurement result may be determined by the terminal device based on the measured layer 1 beam measurement result. In this way, the number of measurement results sent by the terminal device to the network device is reduced, which can reduce the signaling overhead of the air interface.
[0090] Two embodiments of the present application are introduced below.
[0091] Example 1
[0092] The inventors believe that when a terminal device needs to send a large number of Layer 1 measurement results to a network device, the existing methods of periodically or semi-statically sending UCI using the PUCCH and aperiodically or semi-statically sending UCI using the PUSCH are no longer suitable. This is because the PUCCH is a control channel with limited capacity and low reliability, making it inappropriate to use it to carry a large number of Layer 1 measurement results. When using the PUSCH for transmission, these results can only be sent aperiodically or semi-statically, requiring the network device to send a large amount of activation signaling or trigger signaling, which also results in high signaling overhead.
[0093] Based on this, the inventors propose that a new reporting approach can be used to send layer 1 measurement results, which is beneficial for ensuring that a large number of physical layer measurement results can be effectively reported and at the same time helps to avoid PUCCH congestion. The reporting approach of this application is introduced below.
[0094] Method 1: Periodically send layer 1 measurement results via PUSCH
[0095] In some embodiments, the network device may instruct the terminal device to periodically send layer 1 measurement results via the PUSCH.
[0096] In some embodiments, when instructing a terminal device to periodically transmit layer 1 measurement results via a PUSCH, the network device may also indicate the radio resources (such as time domain resources, frequency domain resources, etc.) for periodically transmitting the PUSCH. In this way, the terminal device may periodically transmit a PUSCH on the radio resources indicated by the network device, where the PUSCH carries the layer 1 measurement results.
[0097] In some embodiments, when the network device does not instruct the terminal device on how to send the layer 1 measurement results, the terminal device may default to using PUSCH for periodic transmission. For example, the terminal device may default to using dedicated resources configured by the network device to periodically send PUSCH carrying the layer 1 measurement results.
[0098] In some embodiments, when the layer 1 measurement result is periodically transmitted via the PUSCH, the layer 1 measurement result is encoded with information via a physical layer protocol and is directly transmitted via a physical layer procedure.
[0099] In some embodiments, after the network device receives the layer 1 measurement results sent by the terminal device via the PUSCH, it needs to pass the received layer 1 measurement results to the higher layer through the inter-layer interface between the physical layer and the higher layer. This is because, in some scenarios, the higher layer of the network device needs the measurement results. For example, in a scenario where an AI / ML model is deployed on the network device side for RRM measurement prediction or mobility event prediction, the AI / ML model is generally managed by the higher layer of the network device, so the higher layer of the network device needs the measurement results for RRM measurement prediction or mobility event prediction.
[0100] Compared to the method where terminal devices send Layer 1 measurement results via PUCCH, the method of periodically sending Layer 1 measurement results via PUSCH can carry more data and has higher reliability. Compared to the method where terminal devices send Layer 1 measurement results via PUSCH aperiodically or semi-statically, the method of periodically sending Layer 1 measurement results via PUSCH can avoid the network equipment sending activation signaling or scheduling signaling, which helps to save signaling overhead. In addition, when sending Layer 1 measurement results via PUSCH, the PUSCH capacity is large and the transmission rate is faster.
[0101] Method 2: Sending layer 1 measurement results via high-level messages
[0102] In some embodiments, the "higher layer" mentioned in the embodiments of the present application may refer to a layer located above the physical layer. For example, the higher layer may refer to the MAC layer, and a higher layer message may refer to a MAC layer message, such as a MAC CE message. For another example, the higher layer may refer to the RRC layer, and a higher layer message may refer to an RRC layer message, such as an RRC message. Of course, the higher layer mentioned in the embodiments of the present application may also refer to other layers located above the physical layer, and the higher layer message may also refer to other higher layer messages.
[0103] By sending the measurement results of layer 1 through high-layer messages, on the one hand, there is no need for network devices to instruct activation signaling or scheduling signaling, saving signaling overhead; on the other hand, using high-layer messages to send the measurement results of layer 1 has higher reliability.
[0104] Two examples are given below, taking the high-layer message including the RRC layer message or the MAC layer message as an example.
[0105] Method 2.1: Sending Layer 1 measurement results via RRC layer messages
[0106] Taking the RRC layer message as an RRC message as an example, the terminal device can report the obtained layer 1 measurement result by carrying it in the RRC message in the form of an RRC information element (IE).
[0107] In some embodiments, the RRC message may be, for example, an existing RRC message carrying a measurement report. It should be understood that the measurement result carried in the existing RRC message is a layer 3 measurement result.
[0108] In some embodiments, the RRC message used to carry the measurement results of Layer 1 may reuse the format of an existing RRC message, and a new IE may be added to the existing RRC message, where the new IE may be used to indicate the measurement results of Layer 1. It should be noted that reusing the format of the existing RRC message does not necessarily mean that the measurement results of Layer 1 and Layer 3 must be combined and sent in one RRC message.
[0109] In some embodiments, if the terminal device has both layer 3 measurement results and layer 1 measurement results that need to be reported, the terminal device may combine the layer 1 measurement results and the layer 3 measurement results into one RRC message for reporting.
[0110] In some embodiments, if the terminal device has both layer 3 measurement results and layer 1 measurement results that need to be reported, the terminal device can report the layer 1 measurement results and layer 3 measurement results separately in different RRC messages. This is because the purpose of reporting the layer 1 measurement results and the purpose of reporting the layer 3 measurement results may be different, which may further cause the key parameters (such as the period) of the RRC message to be different. Therefore, different RRC messages can be used to report the layer 1 measurement results and layer 3 measurement results respectively.
[0111] In some embodiments, if the network device does not instruct the terminal device on how to send the layer 1 measurement results, the terminal device may default to using RRC messages. In other words, the default reporting method for the layer 1 measurement results may be RRC message reporting.
[0112] The embodiment of the present application uses RRC messages to send the measurement results of layer 1. On the one hand, the existing sending / receiving mechanism is slightly changed because the existing layer 3 measurement results are sent using RRC messages; on the other hand, the reliability of the measurement results of layer 1 sent through RRC messages is higher.
[0113] Method 2.2: Sending Layer 1 measurement results via MAC layer messages
[0114] Taking the MAC layer message as a MAC CE message as an example, the terminal device can encode the obtained layer 1 measurement result according to the encoding method of the MAC layer information and send it to the network device.
[0115] In some embodiments, the MAC CE may be a new MAC CE. For example, the MAC CE may include a new logical channel identifier (LCID) or a new extended logical channel identifier (eLCID).
[0116] In some embodiments, the MAC CE may be a MAC CE dedicated to carrying layer 1 measurement results.
[0117] In some embodiments, the network device may instruct the terminal device to send the layer 1 measurement result via MAC CE.
[0118] In some embodiments, when the network device does not instruct the terminal device on which method to use to send the layer 1 measurement result, the terminal device may use MAC CE by default.
[0119] The embodiment of the present application does not specifically limit the format of the MAC CE. Exemplarily, the format of the MAC CE may include one or more of a first field, a second field, a third field, a fourth field, and a fifth field.
[0120] The first field may be used to indicate identification information of a cell reported by the terminal device. For example, the first field may be used to indicate a physical cell identifier (PCI) of a cell reported by the terminal device.
[0121] The embodiment of the present application does not limit the number of bits of the first field. For example, the first field can occupy 8 bits.
[0122] The second field may be used to indicate the granularity of the measurement result reported by the terminal device. For example, the second field may be used to indicate whether the terminal device reports a cell measurement result of layer 1 or a beam measurement result of layer 1.
[0123] In some embodiments, the second field may further indicate which reference signal the terminal device is reporting the beam measurement result based on. For example, the second field may be used to indicate whether the terminal device is reporting the beam measurement result based on layer 1 of a synchronization signal block (SSB) or based on layer 1 of a channel state information reference signal (CSI-RS).
[0124] The embodiment of the present application does not limit the number of bits of the second field. Exemplarily, the second field may occupy 2 bits to indicate the granularity of the four reported measurement results.
[0125] The third field may be used to indicate the type of measurement result reported by the terminal device. For example, the third field may be used to indicate which type of measurement result reported by the terminal device is: RSRP of layer 1, RSRQ of layer 1, or SINR of layer 1.
[0126] The embodiments of the present application do not limit the number of bits of the third field. For example, the third field may occupy 2 bits to indicate 4 types of reported measurement results. Alternatively, the third field may occupy 3 bits to indicate 8 types of reported measurement results.
[0127] The fourth field can be used to indicate the index of the measurement result of layer 1 reported by the terminal device. In some embodiments, the IE corresponding to the fourth field exists only when the terminal device reports the beam measurement result of layer 1. In this case, the fourth field is used to indicate the SSB index or CSI-RS index.
[0128] In some embodiments, if the terminal device reports the measurement result of layer 1 based on SSB, the first bit indicated by the fourth field can be filled with 0 to align with the length of the measurement result of layer 1 based on CSI-RS.
[0129] The embodiment of the present application does not limit the number of bits of the fourth field. For example, the fourth field may occupy 3 bytes (Oct) or 4 bytes.
[0130] The fifth field may be used to indicate a specific measurement value. For example, the fifth field may be used to indicate a measurement value of the type of measurement result indicated by the third field.
[0131] In some embodiments, the fifth field is used to indicate an absolute measurement result. In some embodiments, the fifth field is used to indicate a relative measurement result, which is not limited in the present embodiment. For example, the fifth field may use 4 bits to represent 16 relative measurement results (such as 16 differential values or differential range values).
[0132] In some embodiments, when the measurement result reported by the terminal device is a cell measurement result of layer 1, the fifth field has only one value. Otherwise, the number of the fifth field is the same as the number of the fourth field, or in other words, the fifth field corresponds to the fourth field one-to-one.
[0133] The embodiment of the present application does not limit the number of bits of the fifth field. For example, the fifth field may occupy 3 bytes (Oct) or 4 bytes.
[0134] Two examples of MAC CE are given below in conjunction with FIG4 and FIG5 .
[0135] Referring to Figures 4 and 5, "B" in the figures is used to indicate the granularity of the measurement results reported by the terminal device, and "B" can occupy 2 bits. For example, when "B" takes the value of "00", it can indicate that the cell measurement result of layer 1 is reported, when "B" takes the value of "01", it can indicate that the beam measurement result of layer 1 based on SSB is reported, when "B" takes the value of "10", it can indicate that the beam measurement result of layer 1 based on CSI-RS is reported, and the code point "11" is reserved. However, the embodiments of the present application are not limited to this. For example, when "B" takes the value of "00", it can indicate that the beam measurement result of layer 1 based on SSB is reported, when "B" takes the value of "01", it can indicate that the beam measurement result of layer 1 based on CSI-RS is reported, when "B" takes the value of "10", it can indicate that the cell measurement result of layer 1 is reported, etc. For the sake of brevity, it will not be repeated here.
[0136] The "Q" in the figure is used to indicate the type of measurement results reported by the terminal device. The embodiment of the present application does not limit the type of measurement results reported by the terminal device. In some embodiments, the types of measurement results that the terminal device can report may include one or more of the following: RSRP of layer 1, RSRQ of layer 1, SINR of layer 1. In some embodiments, the terminal device can also use the MAC CE to report other measurement results in addition to the measurement results of layer 1, such as the measurement results of layer 3. In this case, the terminal device can report more types of measurement results. For example, the types of measurement results that the terminal device can report may include one or more of the following: RSRP of layer 1, RSRQ of layer 1, SINR of layer 1, RSRP of layer 3, RSRQ of layer 3, SINR of layer 3, etc.
[0137] Taking Figure 4 as an example, "Q" occupies 2 bits to indicate the type of measurement result reported by the terminal device. For example, when the value of "Q" is "00", it means that the RSRP of layer 1 is reported, when the value of "Q" is "01", it means that the RSRQ of layer 1 is reported, and when the value of "Q" is "10", it means that the SINR of layer 1 is reported. Code point "11" is reserved. However, the embodiment of the present application is not limited to this, and the value of "Q" can also be other permutations and combinations.
[0138] Taking Figure 5 as an example, "Q" occupies 3 bits to indicate the type of measurement result reported by the terminal device. For example, when the value of "Q" is "000", it means that the RSRP of layer 1 is reported, when the value of "Q" is "001", it means that the RSRQ of layer 1 is reported, when the value of "Q" is "010", it means that the SINR of layer 1 is reported, when the value of "Q" is "011", it means that the RSRP of layer 3 is reported, when the value of "Q" is "101", it means that the RSRQ of layer 3 is reported, when the value of "Q" is "110", it means that the SINR of layer 3 is reported, and the code point "100" and the code point "111" are reserved. However, the embodiments of the present application are not limited to this, and the value of "Q" can also be other permutations and combinations, or the reserved code points can also be other code points, etc.
[0139] The "RS Index_i" and "RESULT_i" in the figure are used to indicate the index of the layer 1 measurement result reported by the terminal device and the corresponding measurement value, respectively. In some embodiments, the RS Index_i IE only exists when "B" indicates the beam measurement result of layer 1 (such as the beam measurement result of layer 1 based on SSB or the beam measurement result of layer 1 based on CSI-RS).
[0140] In some embodiments, when "B" indicates a beam measurement result of layer 1 based on SSB, RS Index_i represents an SSB index.
[0141] In some embodiments, when “B” indicates a beam measurement result of layer 1 based on SSB, the first bit of RS Index_i may be 0.
[0142] In some embodiments, when "B" indicates a beam measurement result of layer 1 based on CSI-RS, RSIndex_i represents a CSI-RS index.
[0143] In some embodiments, when "B" indicates the cell measurement result of layer 1, RESULT_i has only one value, namely, RESULT_1. Otherwise, RESULT_i corresponds to RS Index_i one-to-one.
[0144] It should be noted that when using different reporting methods to report the same measurement result, the value of the measurement result remains unchanged, only the encoding method used to encode it into a specific format is different. For example, if PUSCH periodic reporting is used, the encoding can refer to the specification TS 38.212; if RRC message reporting is used, the encoding format can be ASN.1.
[0145] The above describes several new reporting methods involved in this application. The following describes the process of sending the measurement results of layer 1.
[0146] Figure 6 is a schematic flow chart of a wireless communication method provided in Example 1. The method shown in Figure 6 is described from the perspective of interaction between a terminal device and a network device. The terminal device and network device may be, for example, terminal device 120 and network device 110 shown in Figure 1. The method shown in Figure 6 may include step S610, which is described below.
[0147] In step S610, the terminal device sends a measurement report to the network device. The measurement report includes the measurement result of the physical layer, or in other words, the measurement report includes the measurement result of layer 1.
[0148] In the embodiment of the present application, the measurement report may be sent periodically via the PUSCH, or may be sent via a high-level message.
[0149] In some embodiments, sending the measurement report through a higher layer message may mean that the measurement report may be sent through an RRC message.
[0150] In some embodiments, sending the measurement report through a higher layer message may mean that the measurement report may be sent through a MAC CE message.
[0151] For a detailed description of how to send periodically through PUSCH or how to send through high-layer messages, please refer to the previous introduction. For the sake of brevity, it will not be repeated here.
[0152] In some embodiments, the measurement results included in the measurement report may include one or more of the following: beam measurement results, cell measurement results. That is, the measurement report may include beam measurement results of layer 1 and / or cell measurement results of layer 1.
[0153] In some embodiments, the measurement results included in the measurement report are absolute measurement results, that is, the measurement results included in the measurement report are results obtained by measuring each cell or each reference signal itself.
[0154] In some embodiments, the measurement results included in the measurement report include absolute measurement results and relative measurement results. In other words, the measurement results are reported in a differential reporting manner. That is, the measurement results included in the measurement report may include a first measurement result and a second measurement result, wherein the first measurement result is a measurement result of a reference cell or a reference beam, and the second measurement result is a relative measurement result relative to the first measurement result.
[0155] For the relevant introduction on how to report the measurement results in a differential reporting manner, please refer to the relevant introduction of the second embodiment, which will not be described here for the sake of brevity.
[0156] In some embodiments, the measurement report may include other information in addition to the measurement result, which is not limited in the embodiments of the present application. For example, the measurement report may include one or more of the following information: information about the cell corresponding to the measurement result, information about the type of the measurement result, and information about the reference signal corresponding to the measurement result. In other words, the terminal device can tell the network device which cell and / or reference signal the measurement result it reports is related to, and can also tell the network device which type of measurement result it reports.
[0157] In some embodiments, the information of the cell corresponding to the measurement result may include identification information of the cell. The embodiment of the present application does not limit the identification information of the cell. For example, the identification information of the cell may be PCI.
[0158] The embodiment of the present application does not limit the type of measurement result. Exemplarily, the type of measurement result may include one or more of the following: RSRP of layer 1, RSRQ of layer 1, and SINR of layer 1.
[0159] In some embodiments, if the terminal device reports a layer 1 beam measurement result, the terminal device may indicate information of a reference signal corresponding to the measurement result in the measurement report.
[0160] The embodiment of the present application does not limit the reference signal corresponding to the measurement result. Exemplarily, the reference signal may be one or more of the following: SSB, CSI-RS.
[0161] In some embodiments, the reference signal information corresponding to the measurement result may include: identification information of the reference signal (e.g., a reference signal index). As an example, if the terminal device reports a beam measurement result of layer 1 based on an SSB, the measurement report may include the SSB index. As another example, if the terminal device reports a beam measurement result of layer 1 based on a CSI-RS, the measurement report may include the CSI-RS index.
[0162] In some embodiments, if the measurement result includes a cell measurement result, the measurement report may include one or more of the following: cell identification information, a cell measurement result corresponding to the cell, and a type of the cell measurement result. As an example, if the measurement result includes a cell measurement result, the measurement report may include the cell identification information and the cell measurement result corresponding to the cell. As another example, if the measurement result includes a cell measurement result, the measurement report may include the cell identification information, the cell measurement result corresponding to the cell, and the type of the cell measurement result (e.g., RSRP of Layer 1).
[0163] In some embodiments, if the measurement result includes a beam measurement result, the measurement report may include one or more of the following: cell identification information, reference signal identification information, beam measurement result corresponding to the reference signal, and type of beam measurement result. As an example, if the measurement result includes a beam measurement result, the measurement report may include cell identification information, reference signal identification information, and beam measurement result corresponding to the reference signal. As another example, if the measurement result includes a beam measurement result, the measurement report may include cell identification information, reference signal identification information, beam measurement result corresponding to the reference signal, and type of beam measurement result (such as RSRP of layer 1).
[0164] In some embodiments, the beam measurement results reported by the terminal device may be one or more beam measurement results for one cell. However, the embodiments of the present application are not limited thereto, and the beam measurement results reported by the terminal device may also be for multiple cells.
[0165] In some embodiments, the measurement report reported by the terminal device may include other information in addition to the above information. For example, the measurement report may also include indication information for indicating the granularity of the measurement result. For example, the measurement report may include an indication information indicating whether the measurement result is a cell measurement result or a beam measurement result.
[0166] In some embodiments, the reporting of the measurement result is determined based on the first configuration information. The first configuration information may be sent by the network device, for example. The following describes the process in conjunction with FIG7 .
[0167] Figure 7 is a schematic flow chart of another wireless communication method provided in Example 1. The method shown in Figure 7 may include step S710 and step S720.
[0168] In step S710, the terminal device receives first configuration information sent by the network device.
[0169] The embodiments of this application do not limit the configuration granularity of the first configuration information. For example, the configuration granularity of the first configuration information may include one or more of the following: terminal device, measurement object, or measurement task. In other words, the first configuration information may be configured for a terminal device, a measurement object, or a measurement task.
[0170] In some embodiments, the first configuration information being configured for the terminal device may mean that the first configuration information is configured for all measurement objects of the terminal device.
[0171] In some embodiments, the first configuration information being configured for the terminal device may mean that the first configuration information is configured for all measurement tasks of the terminal device.
[0172] In some embodiments, the first configuration information being configured for the measurement object may mean that the first configuration information is configured for all measurement tasks corresponding to the configured measurement object.
[0173] In some embodiments, the first configuration information being configured for a measurement task may mean that the first configuration information is configured for a single measurement task.
[0174] In some embodiments, the first configuration information may be RRC measurement configuration information.
[0175] In some embodiments, the first configuration information may be, for example, a measurement configuration.
[0176] In some embodiments, the first configuration information may include first indication information, and the first indication information may be used to indicate type information of the measurement result reported by the terminal device. In other words, the network device may indicate to the terminal device the type of measurement result to be reported.
[0177] In some embodiments, the type of the measurement result indicated by the first indication information may include one or more of the following: RSRP of layer 1, RSRQ of layer 1, and SINR of layer 1.
[0178] In some embodiments, the first indication information may indicate only one type of measurement result, so that the terminal device may report the measurement result of this type to the network device in a measurement report.
[0179] In some embodiments, the first indication information may indicate multiple measurement result types. Thus, the terminal device may select at least one of the indicated measurement result types for measurement and reporting. In this case, the terminal device may report the measurement result of that type in the measurement report and inform the network device of the type of measurement result being reported.
[0180] In some embodiments, the first configuration information may further include second indication information, and the second indication information may be used to indicate a sending method of the measurement report.
[0181] In some embodiments, the sending manner of the measurement report indicated by the second indication information may include one or more of the following: PUSCH periodic sending, and high-layer message sending.
[0182] In some embodiments, the sending manner of the measurement report indicated by the second indication information may include one or more of the following: PUSCH periodic sending, RRC message sending, and MAC CE message sending.
[0183] In some embodiments, if the second indication information indicates that the measurement report is sent in a manner of periodic PUSCH transmission, the first configuration information may further include radio resources for periodic PUSCH transmission.
[0184] In the embodiment of the present application, the radio resource for periodically transmitting the PUSCH configured by the first configuration information can be used to send the measurement result of layer 1. The embodiment of the present application does not limit the radio resource for periodically transmitting the PUSCH indicated by the first configuration information. For example, the first configuration information can configure one or more of the following information of the radio resource: period, time-frequency domain resources, coding mode, modulation and demodulation information, etc.
[0185] In some embodiments, if the second indication information indicates that the measurement report is to be sent periodically via the PUSCH, the measurement report sent by the terminal device is encoded using the physical layer protocol and sent directly via the physical layer. For example, the terminal device may encode the measurement result obtained by the measurement according to the UCI information encoding method and report it via the PUSCH.
[0186] In step S720, the terminal device sends a measurement report to the network device, where the measurement report includes layer 1 measurement results.
[0187] For the introduction of step S720, please refer to the relevant description of step S610 above, and for the sake of brevity, it will not be repeated here.
[0188] Example 2
[0189] The inventor believes that when a terminal device needs to send a large number of measurement results (layer 1 measurement results and / or layer 3 measurement results) to a network device, if the existing measurement result reporting content is used, it will lead to a large signaling overhead. This is because, in the existing measurement reports, the measurement results are basically absolute measurement results. For example, when reporting the RSRP of a cell, the value reported by the terminal device has 7 bits, and the corresponding RSRP table is in the 128 ranges below -31dbm. If the purpose is for mobility management, that is, switching, then in general, the decision on switching candidate cells is more concerned with the case where the measurement results between the serving cell and the neighboring cell are not much different, so reporting the absolute measurement results of the serving cell and the neighboring cell actually introduces too much signaling overhead.
[0190] Based on this, the inventors propose that the content of the reported measurement results can be updated to reduce signaling overhead. The following describes the content of the updated reported measurement results in this application.
[0191] In this embodiment of the present application, a terminal device may report measurement results using differential reporting. In other words, the terminal device may report absolute measurement results for a reference cell or reference beam, while measurement results for other cells or other beams may be relative measurement results relative to the reference cell or reference beam. This is described in detail below in conjunction with Figure 8.
[0192] Figure 8 is a schematic flow chart of a wireless communication method provided in Example 2. The method shown in Figure 8 is described from the perspective of interaction between a terminal device and a network device. The terminal device and network device may be, for example, terminal device 120 and network device 110 shown in Figure 1. The method shown in Figure 8 includes step S810, which is described below.
[0193] In step S810, the terminal device sends a measurement result to the network device.
[0194] In the embodiment of the present application, the measurement result may include a first measurement result and a second measurement result. The first measurement result is a measurement result of a reference cell or a reference beam. The second measurement result is a measurement result of other cells or other beams.
[0195] In the second embodiment, the first measurement result is an absolute measurement result, and the second measurement result is a relative measurement result relative to the first measurement result. In other words, the first measurement result is an absolute measurement result, and the second measurement result is a difference value between the first measurement result and the second measurement result.
[0196] Taking the first measurement result as an example of a measurement result of a reference cell, the second measurement result is a relative measurement result relative to the measurement result of the reference cell, or in other words, the second measurement result is a difference value between other cells and the reference cell.
[0197] Taking the first measurement result being the measurement result of the reference beam as an example, the second measurement result is a relative measurement result relative to the measurement result of the reference beam, or in other words, the second measurement result is a difference value between other beams and the reference beam.
[0198] In some embodiments, the other beams and the reference beam may be located in the same cell. In some embodiments, the other beams and the reference beam may be located in different cells. In other words, the "other beams" mentioned in the embodiments of the present application may refer to beams located in the same cell as the reference beam or in different cells.
[0199] In some embodiments, the measurement result may be a measurement result of layer 1. In some embodiments, the measurement result may be a measurement result of layer 3. However, the present application is not limited thereto. For example, the measurement result may also be a measurement result of layer 2.
[0200] In some embodiments, after obtaining the measurement results, the network device may determine the absolute measurement results of other cells or the absolute measurement results of other beams based on the measurement results reported by the terminal device.
[0201] In some embodiments, the absolute measurement results of other cells are determined based on the absolute measurement result of the reference cell and the relative measurement results of other cells. As an implementation, the absolute measurement results of other cells may be equal to the sum of the absolute measurement result of the reference cell and the relative measurement results of other cells.
[0202] In some embodiments, the absolute measurement results of the other beams are determined based on the absolute measurement result of the reference beam and the relative measurement results of the other beams. As an implementation, the absolute measurement results of the other beams may be equal to the sum of the absolute measurement result of the reference beam and the relative measurement results of the other beams.
[0203] In some embodiments, if the relative measurement result of other cells or other beams is a range value [a, b], and the absolute measurement result of the reference cell or reference beam is a range value [c, d], then the absolute measurement result of other cells or other beams can be equal to [a+c, b+d].
[0204] In some embodiments, if the relative measurement result of other cells or other beams is a specific value a, and the absolute measurement result of the reference cell or reference beam is a range value [c, d], then the absolute measurement result of other cells or other beams can be equal to [a+c, a+d].
[0205] In some embodiments, after obtaining the measurement results, the network device may directly use the reported measurement results. For example, when the network device predicts an A3 event or an A6 event, the reported relative measurement results may be directly used as input parameters of the prediction model.
[0206] In some embodiments, the type of measurement result reported by the terminal device may include one or more of the following: RSRP difference of layer 1, RSRQ difference of layer 1, SINR difference of layer 1, RSRP difference of layer 3, RSRQ difference of layer 3, and SINR difference of layer 3. In other words, the relative measurement result proposed in the embodiment of the present application can be applied to different types of measurement results. For different types of measurement results, the determination method of the reference cell and / or reference beam is similar, but the specific quantization results may be different.
[0207] In some embodiments, the type of measurement result reported by the terminal device may include one or more of the following: RSRP difference of layer 1, RSRQ difference of layer 1, and SINR difference of layer 1. For example, when the terminal device reports the measurement result through MAC CE or through PUSCH, the type of measurement result reported may include one or more of the following: RSRP difference of layer 1, RSRQ difference of layer 1, and SINR difference of layer 1.
[0208] In some embodiments, if the measurement result differentially reported by the terminal device is a layer 3 measurement result, the terminal device may report the layer 3 measurement result via an RRC message.
[0209] It should be understood that the above-mentioned "RSRP differential of layer 1" may mean that the RSRP of layer 1 is reported in a differential reporting manner when reporting the measurement results. The explanations of other measurement result types are similar and will not be repeated here for the sake of brevity. In some embodiments, for intra-frequency measurement tasks, the type of the above-mentioned measurement results also implicitly indicates to the terminal device that what needs to be reported is the relative measurement result of the neighboring cell rather than the absolute measurement result, and its reference cell is PCell, PSCell or SCell (depending on the frequency point and subcarrier spacing parameters in the measurement object).
[0210] In some embodiments, for inter-frequency measurement tasks, the measurement result type implicitly indicates to the terminal device that the measurement result of the neighboring cell should be reported as a relative measurement result rather than an absolute measurement result. In this case, if the network device wants to specify a reference cell, the network device may also need to configure the reference cell information.
[0211] In some embodiments, the relative measurement results may be indicated using indices. As an implementation, an index may correspond to a range of measurement values, such as [3, 4) or [-1, 0), where [] indicates the range is inclusive and () indicates the range is exclusive. Alternatively, the relative measurement results may be directly quantized using indices, where an index directly represents a differential value, such as 5dB or -3dB.
[0212] In some embodiments, the relative measurement results include one or more of the following: a positive value, a negative value, and zero.
[0213] In some embodiments, the relative measurement results may be represented using a limited number of information bits, which is shorter than the information bits used for absolute measurement values. Currently, the specification uses 7 bits to represent RSRP, RSRQ, and SINR, so the relative measurement results must occupy at least 7 bits.
[0214] In some embodiments, when a terminal device reports measurement results of other cells, whether to report absolute measurement results of other cells or relative measurement results of other cells is configured by the network device. As an implementation method, the network device can send second configuration information to the terminal device, where the second configuration information is used to indicate the reporting method of the measurement results.
[0215] In some embodiments, the reporting method of the measurement result may include absolute value reporting and differential reporting. That is, the second configuration information may be used to indicate whether the reporting method of the measurement result is absolute value reporting or differential reporting. Absolute value reporting may mean that the measurement results of all cells (regardless of the reference cell and other cells) are absolute measurement results. Differential reporting may mean that the measurement result of the reference cell is an absolute measurement result, and the measurement results of other cells are relative measurement results.
[0216] In some embodiments, if the second configuration information indicates that the reporting method of the measurement result is differential reporting, the measurement result included in the measurement report includes the first measurement result and the second measurement result mentioned above.
[0217] Example 2 adopts a differential reporting mechanism, that is, reporting the absolute measurement results of the reference cell / reference beam and the relative measurement results of other cells / other beams. Compared with the solution in which the measurement results of all cells / all beams use absolute measurement results, the relative measurement results occupy fewer bits than the absolute measurement results, and the overall signaling overhead will also be reduced.
[0218] Similarly, when reporting CSI, the related technology introduces a differential reporting mechanism for the RSRP of layer 1 and the SINR of layer 1 reported by the physical layer. Specifically, after the terminal device reports the measurement result of the beam with the best quality, the measurement results of other beams are reported in a differential manner. When reporting CSI, the reference beam selected is the best beam (the strongest signal in the reference signal). Since other beams are differentials from the best beam, the differential values in the measurement results are all less than or equal to 0. However, this method is not suitable for the RRM measurement reporting method for mobility management, because when the terminal device is close to the neighboring cell, the signal of the neighboring cell is near the signal of the serving cell, and there may be multiple possibilities for the difference. So, how to determine the reference cell corresponding to the measurement result is a problem that needs to be solved.
[0219] In some embodiments, the reference cell may include one of the following: a primary cell (PCell), a primary secondary cell (PSCell), a secondary cell (SCell), and a neighboring cell.
[0220] Taking the PCell as the reference cell, when reporting measurement results, the terminal device may always report the absolute measurement results of the PCell. For measurement results of other cells, the difference between the measurement results of other cells and the PCell is reported. In other words, the first measurement result in the measurement results reported by the terminal device is the absolute measurement result of the PCell, and the second measurement result is the relative measurement result of the measurement results of other cells relative to the PCell (the difference between the absolute measurement results of other cells and the PCell).
[0221] Taking the reference cell as PSCell as an example, when reporting measurement results, the terminal device can always report the absolute measurement results of the PSCell. For the measurement results of other cells, the difference between the measurement results of other cells and PSCell is reported. In other words, the first measurement result in the measurement results reported by the terminal device is the absolute measurement result of the PSCell, and the second measurement result is the relative measurement result of the measurement results of other cells relative to the PSCell (the difference between the absolute measurement results of other cells and PSCell).
[0222] Taking the SCell as the reference cell, when reporting measurement results, the terminal device may always report the absolute measurement results of the SCell. For measurement results of other cells, the difference between the measurement results of other cells and the SCell is reported. In other words, the first measurement result in the measurement results reported by the terminal device is the absolute measurement result of the SCell, and the second measurement result is the relative measurement result of the measurement result of the other cell relative to the SCell (the difference between the absolute measurement results of the other cell and the SCell).
[0223] Taking the first neighboring cell as the reference cell as an example, when reporting measurement results, the terminal device may always report the absolute measurement result of the first neighboring cell. For the measurement results of other cells, the difference between the measurement results of the other cells and the first neighboring cell is reported. In other words, the first measurement result in the measurement results reported by the terminal device is the absolute measurement result of the first neighboring cell, and the second measurement result is the relative measurement result of the other cells relative to the measurement result of the first neighboring cell (the difference between the absolute measurement results of the other cells and the first neighboring cell).
[0224] In some embodiments, if the measurement corresponding to the measurement result is an intra-frequency measurement, the reference cell may be one of the following: PCell, PSCell, or SCell. As an example, for an intra-frequency measurement task at the frequency point where the PCell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the PCell. As another example, for an intra-frequency measurement task at the frequency point where the PScell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the PSCell. As yet another example, for an intra-frequency measurement task at the frequency point where the SCell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the SCell.
[0225] In some embodiments, if the measurement corresponding to the measurement result is an inter-frequency measurement, the reference cell may be one of the following: PCell, PSCell, SCell, or a neighboring cell. As an example, for an inter-frequency measurement task that is not at the frequency point where any serving cell is located, the reference cell corresponding to the measurement result reported by the terminal device may be a neighboring cell. As another example, for an inter-frequency measurement task at the frequency point where the PCell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the PCell. As another example, for an inter-frequency measurement task at the frequency point where the PScell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the PSCell. As yet another example, for an inter-frequency measurement task at the frequency point where the SCell is located, the reference cell corresponding to the measurement result reported by the terminal device may be the SCell.
[0226] In some embodiments, the reference cell and / or reference beam may be configured by a network device.
[0227] In some embodiments, the reference cell may be configured by the network device in one or more of the following ways: an identifier of the reference cell, a default reference cell corresponding to a measurement event associated with the measurement result.
[0228] In some embodiments, the network device may explicitly configure a reference cell. For example, the network device may indicate an identifier (such as a PCI) of the reference cell. Alternatively, the network device may mark the reference cell with other explicit information. As an implementation, the network device may explicitly mark a cell as a reference cell in the measurement report (MeasConfig) in the measurement task.
[0229] In some embodiments, if the network device does not directly configure a reference cell, the terminal device may use the default reference cell corresponding to the measurement event. For example, for events A1 / A2 / A3 / A4 / A5, the default reference cell is PCell or PSCell, and the reference cell mentioned in this application may be configured as PCell or PSCell accordingly. Alternatively, for event A6, the default reference cell is SCell, and the reference cell mentioned in this application may be configured as SCell accordingly.
[0230] In some embodiments, the reference beam may be configured by the network device in one or more of the following ways: an identifier of a reference signal corresponding to the reference beam, a default reference signal corresponding to a measurement object associated with a measurement result.
[0231] In some embodiments, the network device may explicitly configure the reference beam. For example, the network device may indicate the identifier of the reference signal corresponding to the reference beam (such as an SSB index or a CSI-RS index).
[0232] In some embodiments, if the network device does not directly configure a reference beam, the terminal device may use a default reference signal corresponding to the measurement object as the reference beam. For example, the terminal device may use a default SSB or a default CSI-RS as the reference beam.
[0233] The embodiments of the present application do not limit the default reference signal corresponding to the measurement object. As an example, the default reference signal may be the reference signal with the smallest index number included in the measurement object. As another example, the default reference signal may be the reference signal with the largest index number included in the measurement object.
[0234] In some embodiments, the above-mentioned reference cell and / or reference beam is determined by the terminal device.
[0235] In some embodiments, if the reference cell and / or reference beam is determined by the terminal device, the terminal device may further indicate relevant information of the determined reference cell and / or reference beam to the network device. As an example, the terminal device may send first information to the network device, where the first information is used to indicate the reference cell and / or reference beam.
[0236] In some embodiments, the first information may be carried in the same measurement report as the measurement result. That is, the terminal device may report the measurement result and the corresponding first information in the same measurement report. However, the embodiment of the present application is not limited thereto, and the first information may also be reported separately from the measurement result.
[0237] As an implementation manner, if the terminal device reports the first information and the measurement result at the same time, the terminal device may report the first information to the network device when reporting the first measurement result.
[0238] As an implementation method, if the terminal device reports the first information and measurement results separately, the terminal device can report the first information to the network device before reporting the first measurement result; or, the terminal device can report the first information to the network device when reporting the first measurement result.
[0239] Generally speaking, the terminal device does not change the reference cell during the reporting process of a measurement task. If the terminal device changes the reference cell during the reporting process of a measurement task, the terminal device can report the information of the new reference cell to the network device.
[0240] It should be noted that the first and second embodiments proposed in this application can be used in combination or separately. For example, when reporting the measurement report of layer 1, the terminal device can adopt a differential reporting method and can periodically send the measurement result of layer 1 in the PUSCH. Alternatively, when reporting the measurement report of layer 1, the terminal device can adopt a differential reporting method and can send the measurement result of layer 1 in an RRC message or a MAC CE message.
[0241] The combination of the first embodiment and the second embodiment can further reduce signaling overhead.
[0242] In some embodiments, the terminal device may periodically send the measurement results of layer 1 to the network device through PUSCH, or the terminal device may send the measurement results of layer 1 to the network device through a high-layer message (such as an RRC message, a MAC CE message). The measurement result (i.e., the measurement result of layer 1) may include a first measurement result and a second measurement result, wherein the first measurement result is a measurement result of a reference cell or a reference beam, and the second measurement result is a measurement result of other cells or other beams. The first measurement result is an absolute measurement result, and the second measurement result is a relative measurement result relative to the first measurement result.
[0243] In some embodiments, the terminal device may periodically send the measurement results of layer 1 to the network device via PUSCH, or the terminal device may send the measurement results of layer 1 to the network device via a high-layer message (such as an RRC message, a MAC CE message), and the measurement results (i.e., the measurement results of layer 1) are reported in a differential manner.
[0244] In some embodiments, the terminal device may periodically send the measurement results of layer 1 to the network device through PUSCH, or the terminal device may send the measurement results of layer 1 to the network device through a high-layer message (such as an RRC message, a MAC CE message). The measurement result (i.e., the measurement result of layer 1) is reported in a differential manner, and the reference cell corresponding to the measurement result includes one of the following: PCell; PSCell; SCell; neighboring cell.
[0245] In some embodiments, in some embodiments, the terminal device may periodically send the measurement results of layer 1 to the network device through PUSCH, or the terminal device may send the measurement results of layer 1 to the network device through a high-level message (such as an RRC message, a MAC CE message). The measurement result (i.e., the measurement result of layer 1) is reported in a differential manner, and the reference cell and / or reference beam corresponding to the measurement result is configured by the network device.
[0246] As a possible implementation manner, the reference cell is configured by the network device through one or more of the following manners: an identifier of the reference cell, a default reference cell corresponding to a measurement event associated with the measurement result.
[0247] As a possible implementation manner, the reference beam is configured by the network device through one or more of the following methods: an identifier of a reference signal corresponding to the reference beam, and a default reference signal corresponding to a measurement object associated with a measurement result.
[0248] In some embodiments, the terminal device may periodically send layer 1 measurement results to the network device via the PUSCH, or the terminal device may send layer 1 measurement results to the network device via a higher-layer message (such as an RRC message or a MAC CE message). The measurement result (i.e., the layer 1 measurement result) is reported in a differential manner, and the reference cell and / or reference beam corresponding to the measurement result is determined by the terminal device. In some embodiments, after determining the reference cell or reference beam, the terminal device may indicate the determined reference cell or reference beam to the network device.
[0249] It should be noted that other aspects of the combination of Example 1 and Example 2 can be referred to the introduction above. For example, the terminal device can periodically send the measurement result of layer 1 to the network device through PUSCH, or the terminal device can send the measurement result of layer 1 to the network device through a high-layer message (such as an RRC message, a MAC CE message), and the measurement result includes a first measurement result and a second measurement result, and the second measurement result is a relative measurement result relative to the first measurement result. In this case, the relative measurement result can be indicated by an index, or the information bits occupied by the relative measurement result are less than 7 bits, or the relative measurement result can include positive values, negative values or zero, etc. Where there is no detailed description here, please refer to Example 1 or Example 2.
[0250] In some embodiments, when the first embodiment is combined with the second embodiment, the aforementioned method may also have some differences. The following describes the method using the MAC CE to send the measurement result as an example.
[0251] In some embodiments, if the terminal device adopts a differential reporting method and uses a MAC CE message to send measurement results (such as layer 1 measurement results and / or layer 3 measurement results), the design of MAC CE can be as follows.
[0252] For example, the third field in the MAC CE may occupy 3 bits to indicate the type of the reported measurement result. In the second embodiment, the value of the third field may refer to Table 1.
[0253] Table 1
[0254] For another example, the third field in the MAC CE may occupy 2 bits to indicate the type of the reported measurement result. In the second embodiment, the value of the third field may be referred to in Table 2.
[0255] Table 2
[0256] For another example, when reporting relative measurement results, the number of bits occupied by the fifth field can be smaller. For example, when reporting absolute measurement results, the number of bits occupied by the fifth field can be designed to be 8 bits, while when reporting relative measurement results, the number of bits occupied by the fifth field can be designed to be 4 bits, etc.
