[0002] This application claims priority to Chinese Patent Application No. 202410521757.9, filed on April 26, 2024, entitled “Reference Signal Processing Method, Apparatus, Medium and Program Product”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication equipment technology, and in particular to a reference signal processing method, apparatus, medium and program product. Background Technology

[0004] With the rapid development of communication technology, communication frequency bands are increasing, antenna elements are becoming more numerous and larger, beams are narrower, and the number of beams is increasing, making beamforming applications increasingly promising. In future communication networks, the increased number of antennas will make acquiring full-dimensional channels more difficult, while obtaining beam information can achieve high processing gain at a relatively low cost. Beam alignment achieved through beamforming can improve signal transmission quality and stability, increase network coverage and data transmission rates. Beamforming can also better adapt to the needs and environmental conditions of different users (User Equipment, UE), improving network performance.

[0005] In practical applications, network devices transmit measurement reference signals, and terminal devices need to measure these reference signals and report the measurement results to complete beam training. For example, during beam training, the terminal device reports the Reference Signal Receiving Power (RSRP). In practice, on the one hand, users may need to report multiple measurement results separately, resulting in low reporting efficiency; on the other hand, multiple measurement results may be correlated, a characteristic that is not well utilized in current measurement result reporting methods. Summary of the Invention

[0029] To facilitate a better understanding of the solutions in the embodiments of this application, the relevant technologies will be introduced first below.

[0030] In a wireless communication system, communication devices are included, and these devices can communicate wirelessly using air interface resources. The communication devices include network devices and terminal devices. Wireless communication between communication devices includes wireless communication between network devices and terminal devices, and wireless communication between network devices. When communication devices communicate wirelessly using air interface resources, the communication device that manages and / or allocates the air interface resources can also be called a scheduling entity, and the scheduled communication device can also be called a subordinate entity. For example, when a network device and a terminal device communicate wirelessly, the network device can also be called a scheduling entity, and the terminal device can also be called a subordinate entity. The technical solutions provided in this application can be used for wireless communication between scheduling entities and subordinate entities. This application uses wireless communication between network devices and terminal devices as an example to describe the technical solutions provided in this application. Further, in the technical solutions provided in this application: the device that performs the function of a network device can be a network device, or it can be a device A located within the network device that supports the network device in performing this function; device A is also within the protection scope of this application. The device that performs the function of a terminal device can be a terminal device, or it can be a device B located within the terminal device that supports the terminal device in performing this function; device B is also within the protection scope of this application. In the embodiments of this application, the term "wireless communication" can also be simply referred to as "communication", and the term "communication" can also be described as "data transmission".

[0031] The network devices involved in the embodiments of this application include, but are not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission and reception point (TRP or transmission point, TP) in a wireless fidelity (WIFI) system, and may also be gNB in ​​a 5G, such as NR system, or transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or may also be network nodes constituting gNB or transmission point, such as baseband unit (BBU) or distributed unit (DU), etc.

[0032] The terminal device involved in the embodiments of this application can also be called a terminal, which is a device with wireless transceiver capabilities. It can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as ships); and it can also be deployed in the air (such as airplanes, balloons, and satellites). The terminal device can be user equipment (UE), where UE includes handheld devices, vehicle-mounted devices, wearable devices, or computing devices with wireless communication capabilities. For example, UE can be a mobile phone, tablet computer, or computer with wireless transceiver capabilities. The terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on.

[0033] In practical applications, both network devices and terminal devices employ beamforming technology, making transmit / receive beam management a major issue. Beam management includes beam training, beam measurement and reporting, and beam indication for each signal or channel. During beam training, the terminal device needs to measure and report the reference signal (RS) configured by the network device. Currently, terminal devices train beams based on a single beam measurement (i.e., layer 1 reference signal receiving power (L1-RSRP)). Through beam training, the terminal device can find beam pairs that communicate with the network device. The relationship between beam pairs is represented by a QCL relationship. When the network device indicates that this QCL relationship is associated with the reference signal, the terminal device can determine which receive beam to use or which transmit beam to use to transmit the reference signal, thus aligning the behaviors of the network device and the terminal device.

[0034] Beamforming refers to adjusting the beamforming weights transmitted by network devices during signal transmission to better adapt to the environment and conditions of the terminal, thereby improving the quality and stability of signal transmission. In an exemplary embodiment, beamforming may involve the following aspects:

[0035] Beam scanning: By scanning different beam directions, the optimal transmission direction is found, thereby improving the signal reception quality.

[0036] Beamforming: Based on the receiver's feedback and channel state information, the beamforming weights of the transmitter are adjusted to better adapt to the receiver's environment and conditions.

[0037] Channel estimation: By estimating and measuring the channel's state information, we can understand the channel's propagation characteristics and interference, thus providing a basis for downlink beam training.

[0038] During downlink channel measurements and beam calibration, network devices transmit reference signals, and terminal devices need to measure these reference signals and report the measurement results. For example, during beam training, users report RSRP (Reference Reference Point Response). During beam training, users may need to report measurement results multiple times, resulting in low reporting efficiency. Furthermore, multiple measurement results may be correlated, a characteristic that is not well utilized in existing measurement result reporting methods.

[0039] Based on this, this application provides a reference signal processing method, apparatus, medium, and program product for improving the efficiency of terminal devices in reporting measurement results.

[0040] Please refer to Figure 1, which is a flowchart illustrating a reference signal processing method provided in an embodiment of this application. As shown in Figure 1, the reference signal processing method provided in this embodiment includes, but is not limited to, steps S100 and S200:

[0041] Step S100: Determine the set of reference signal resources for joint processing.

[0042] It should be noted that in order to calculate channel state information or perform channel estimation, mobility management, positioning, etc., network devices need to transmit reference signals (RS). Reference signals include, but are not limited to, channel-state information reference signals (CSI-RS), which include zero-power CSI-RS (ZP CSI-RS) and non-zero-power CSI-RS (NZP CSI-RS), channel-state information interference measurement results (CSI-IM), sounding reference signals (SRS), synchronization signal blocks (SSB), physical broadcast channels (PBCH), and synchronization block / physical broadcast channel (SSB / PBCH). NZP CSI-RS can be used to measure channel or interference. CSI-RS can also be used for tracking, called tracking reference signals (CSI-RS for...). Tracking (TRS), while CSI-IM is generally used to measure interference, and SRS is used to measure the uplink channel. Additionally, the time-frequency resources used to transmit reference signals include a set of resource elements (REs) called reference signal resources, such as CSI-RS resource, SRS resource, CSI-IM resource, and SSB resource. The relationship between CSI-RS resource setting, CSI-RS resource set, and CSI-RS resource is shown in Figure 2. A CSI-RS resource setting contains at least one CSI-RS resource set, and a CSI-RS resource set contains at least one CSI-RS resource.

[0043] When the reference signal is an SSB, the resource set can be a single synchronization signal burst set (SSB Burst). This means the base station can instruct the joint processing of reference signal measurement results within a specific SSB burst, or it can instruct the joint processing of measurement results for each SSB burst within an SSB busrt set. The correspondence between SSB burst set, SSB burst, and SSB is shown in Figure 3. An SSB busrt set contains at least one SSB busrt, and an SSB busrt contains at least one SSB.

[0044] The set of reference signal resources for joint processing can be obtained through signaling from the base station. The signaling can be at least one of the following: Downlink Control Information (DCI), Medium Access Control-Control Element (MAC-CE), and Radio Resource.

[0045] In some embodiments, in a communication system, the resources for transmitting reference signals can be referred to as reference signal resources. In order to save signaling overhead, multiple reference signal resources may be divided into multiple sets (such as CSI-RS resource set, CSI-IM resource set, SRS resource set). A reference signal resource set includes at least one reference signal resource, and multiple reference signal resource sets may all come from the same reference signal resource setting (such as CSI-RS resource setting, SRS resource setting, where CSI-RS resource setting may be merged with CSI-IM resource setting and both are referred to as CSI-RS resource setting).

[0046] In some embodiments, the network device configures measurement resource information, which is used to acquire channel state information. The measurement resource information includes CN Channel Measurement Resource (CMR) information and CM Interference Measurement Resource (IMR) information, where CN and CM are positive integers. The base station configures the measurement resource information in a report config or reporting setting. In some examples, a channel measurement resource information includes at least one channel reference signal resource setting, such as at least one CSI-RS resource setting or at least one SRS resource setting; an interference measurement resource information includes at least one interference reference signal resource setting, such as at least one CSI-IM resource setting. In some examples, a channel measurement resource information includes at least one set of channel reference signal resources, such as at least one CSI-RS resource set or at least one SRS resource set; an interference measurement resource information includes at least one set of interference reference signal resources, such as at least one CSI-IM resource set. In some examples, a channel measurement resource information includes at least one channel reference signal resource, such as at least one CSI-RS resource or at least one SRS resource; an interference measurement resource information includes at least one interference reference signal resource, such as at least one CSI-IM resource.

[0047] In some embodiments, a beam includes a transmit beam, a receive beam, a receive beam and a transmit beam pair, and a transmit beam and a receive beam pair. In some embodiments, a beam can be understood as a resource, such as a reference signal resource, a transmit-end spatial filter, a receive-end spatial filter, a spatial filter, spatial receive parameters, transmit-end precoding, receive-end precoding, an antenna port, an antenna weight vector, an antenna weight matrix, etc. A beam index can be replaced with a resource index (e.g., a reference signal resource index) because the beam can be transmittedly bound to some time-frequency code resources. A beam can also be a transmission (transmit / receive) mode; the transmission mode may include spatial division multiplexing, frequency domain / time domain diversity, beamforming, etc. Furthermore, network devices can configure quasi-co-location (QCL) for two reference signals and inform the terminal to describe channel characteristic assumptions. The quasi-co-location parameters include at least Doppler spread, Doppler shift, delay spread, average delay, average gain, and spatial Rx parameter (or spatial parameter). The spatial parameter may include spatial reception parameters, such as angle information, spatial correlation of the received beam, average delay, and correlation of the time-frequency channel response (including phase information). Angle information may include at least one of the following: angle of arrival (AOA), angle of departure (AOD), ZOD (Zenith angle of departure), and ZOA (Zenith angle of arrival). Spatial filtering may be at least one of the following: a DFT vector, a precoded vector, a DFT matrix, a precoded matrix, or a vector formed by a linear combination of multiple DFTs, or a vector formed by a linear combination of multiple precoded vectors. In some examples, index and indicator are interchangeable concepts; in some embodiments, vector and vector array are interchangeable concepts.

[0048] In this embodiment, at least a portion of the reference signal resources in the target reference signal resource set are combined into a joint processing reference signal resource set. By determining the joint processing reference signal resource set, corresponding operations are performed. This determination can be either explicit or implicit, as detailed in the embodiments below.

[0049] After receiving the instruction information, the terminal device can combine at least a portion of the reference signal resources in the corresponding target reference signal resource set into a joint processing reference signal resource set to facilitate joint processing.

[0050] Step S200: Obtain the measurement results of the reference signals corresponding to the joint processing reference signal resource set, and perform joint processing on the measurement results of the reference signals.

[0051] For example, please refer to Figure 4, which is a flowchart illustrating an embodiment of this application for obtaining the measurement results of the reference signals corresponding to the joint processing reference signal resource set and performing joint processing on the measurement results of the reference signals. As shown in Figure 4, in this embodiment, step S200, obtaining the measurement results of the reference signals corresponding to the joint processing reference signal resource set and performing joint processing on the measurement results of the reference signals, may include, but is not limited to, steps S201 to S202:

[0052] Step S201: Obtain the reference signals corresponding to the joint processing reference signal resource set, and determine the measurement results corresponding to each reference signal.

[0053] Step S202: Multiply the measurement results corresponding to all reference signals with the joint processing matrix to obtain the joint processing result.

[0054] It should be noted that the measurement results corresponding to each reference signal may include at least one of the following:

[0055] The reference signal received power corresponding to the reference signal;

[0056] The received signal strength indication corresponding to the reference signal;

[0057] The time-domain sampled value of the reference signal;

[0058] The average of multiple time-domain samples of the reference signal;

[0059] The magnitude of the time-domain sampled value of the reference signal.

[0060] The joint processing result is obtained by multiplying the measurement results corresponding to each reference signal with the joint processing matrix, and then the joint processing result is reported.

[0061] It is understandable that by determining the set of joint processing reference signals, obtaining the measurement results of the reference signals in the set of joint processing reference signals, performing joint processing, and reporting the measurement results, there is no need to process and report them separately. This can improve the reporting efficiency, and after multiple results are processed together, the influence of noise can be suppressed to a certain extent, thereby improving the measurement accuracy.

[0062] It should be noted that, in the embodiments of this application, the joint processing reference signal resource set can be determined by an explicit indication method. When the joint processing reference signal resource set is determined by an explicit indication method, the reference signal resource set sent by the network device carries indication information, and the terminal device processes the received reference signal resource set according to the indication information carried in the reference signal resource set.

[0063] In an exemplary embodiment, please refer to FIG5, which is a flowchart illustrating a method for determining a set of joint processing reference signals resources according to an embodiment of this application. As shown in FIG5, in step S100, determining the set of joint processing reference signals resources may include, but is not limited to, the following steps S101 to S102:

[0064] Step S101: Receive indication information corresponding to the target reference signal resource set sent by the base station.

[0065] Step S102: According to the instruction information, at least a portion of the reference signal resources in the target reference signal resource set are combined into a joint processing reference signal resource set.

[0066] The target reference signal resource set can be any pre-configured reference signal resource set.

[0067] For example, in step S102, according to the instruction information, forming a joint processing reference signal resource set from at least a portion of the reference signal resources in the target reference signal resource set may include any one of the following steps: S102a, S102b, S102c, or S102d.

[0068] Step S102a: According to the instruction information, all reference signal resources in the target reference signal resource set are combined into a joint processing reference signal resource set.

[0069] In an exemplary embodiment, the target bit in the indication information carried in the target reference signal resource set can be used to indicate to the terminal whether the target reference signal resource set is a joint processing reference signal resource set. If so, the measurement results of the reference signals corresponding to all reference signal resources in the target reference signal resource set are jointly processed.

[0070] For example, in one embodiment of this application, the network device uses 1 bit as an indication information to indicate whether the measurement results of all reference signals in the target reference signal resource set are jointly processed. As shown in FIG6, if the target bit position in the indication information of reference signal resource set 1 is 1, then reference signal resource set 1 is determined as a jointly processed reference signal resource set, and the measurement results of all reference signals corresponding to reference signal resource set 1 are subsequently jointly processed; while if the target bit position in the indication information of reference signal resource set 2 is 0, then reference signal resource set 2 is considered as a non-jointly processed reference signal resource set.

[0071] It should be noted that if no indication information for the target reference signal resource set is received, the target reference signal resource set can be assumed to be either the joint processing reference signal resource set or the non-joint processing reference signal resource set.

[0072] Step S102b: Based on the instruction information, determine the reference signal resources in the target reference signal resource set that participate in joint processing, and form a joint processing reference signal resource set by the reference signal resources determined to participate in joint processing.

[0073] For example, the indication information in step S102b may include a bit map, which flexibly indicates which reference signal measurement results in the reference signal resource set received by the user can be jointly processed, thereby determining the reference signal resource set for joint processing.

[0074] As shown in Figure 7, the indication information includes a bitmap. Each bit in the bitmap corresponds to a reference signal resource. If the bit corresponding to a reference signal resource is 1, that reference signal resource is added to the joint processing reference signal resource set. If the bit corresponding to a reference signal resource is 0, that reference signal resource is not added to the joint processing reference signal resource set. In the example shown in Figure 7, the bitmap in the indication information of the reference signal resource set is "11100". The five bits in this bitmap correspond to reference signal resources 1-5 in sequence. Based on this bitmap, reference signal resources 1, 2, and 3 in the reference signal resource set are combined to form a joint processing reference signal resource set. Subsequently, the measurement results of the reference signals of reference signal resources 1, 2, and 3 are jointly processed. However, for the reference signals of reference signal resources 4 and 5, only the measurement results are obtained, and no joint processing is performed.

[0075] It should be noted that, in addition to bitmaps, other indication methods can be used to indicate whether each reference signal resource in the target reference signal resource set is added to the joint processing reference signal resource set. The embodiments of this application do not impose too many limitations on the specific indication method of the indication information.

[0076] Step S102c: Based on the instruction information, determine the group corresponding to each reference signal resource in the target reference signal resource set, and combine the reference signal resources in the same group into a joint processing reference signal resource set.

[0077] The indication information in step S102c may include a bit map, which indicates the grouping of reference signal resources in the target reference signal resource set. The measurement results of the reference signals corresponding to the reference signal resources in the same group can be jointly processed.

[0078] As shown in Figure 8, in the reference signal resource set, each pair of bits in the bit diagram corresponds to one reference signal resource. Reference signal resources with the same two corresponding bits are grouped together and identified as the same joint processing reference signal resource set. In the reference signal resource set shown in Figure 8, reference signal resources 1 and 2 with corresponding bit 00 are grouped into group 1, forming a joint processing reference signal resource set; reference signals 3 and 4 with corresponding bit 01 are grouped into group 2, forming a joint processing reference signal resource set; and reference signals 5 and 6 with corresponding bit 10 are grouped into group 3, forming a joint processing reference signal resource set.

[0079] After grouping, the measurement results of the joint processing reference signal resource sets composed of group 1, group 2 and group 3 are processed separately.

[0080] It should be noted that, in addition to bitmaps, other indication methods can also be used to indicate the grouping of each reference signal resource in the target reference signal resource set. This application embodiment does not impose excessive limitations on the specific indication method of the indication information. Step S102d: Based on the indication information, determine the quantity n, and form a joint processing reference signal resource set from every n reference signal resources in the target reference signal resource set, where n is an integer greater than 1.

[0081] In addition to using bitmaps to group the reference signals in the target reference signal resource set, it is also possible to directly specify that the reference signals in the target reference signal resource set are grouped into arithmetic progressions.

[0082] For example, the indication information is used to indicate a quantity n. Based on the quantity n indicated by the indication information, the terminal groups every n reference signal resources in the target reference signal resource set into a joint processing reference signal resource set. For example, if the quantity n = 2 is determined according to the indication information, the 6 reference signal resources contained in reference signal resource set 1 in Figure 9 are divided into 3 groups according to the principle of grouping every 2 reference signal resources, and each group is a joint processing reference signal resource set.

[0083] By using explicit indication information, the terminal can directly determine which reference signal resources in the target reference information resource set need to be jointly processed, and which reference signal resources need to be jointly processed together, based on the indication information in the received target reference signal resource set.

[0084] It should be noted that, in another aspect of the embodiments of this application, the joint processing reference signal resource set can be determined using an implicit indication method. When the reference signal resource set is determined using an implicit indication method, the reference signal resource set transmitted by the base station does not contain indication information. The user determines the joint processing reference signal resource set based on other information. When using the implicit method, step S100, determining the joint processing reference signal resource set, can include any one of the following steps: S103a, S103b, S103c, or S103d.

[0085] Step S103a: If the transmission frequency band corresponding to the target reference signal resource set meets the preset frequency conditions, the target reference signal resource set is determined to be a joint processing reference signal resource set.

[0086] By associating the measurement results of the reference signal resource set with the transmission frequency band of the system, and by detecting the transmission frequency band corresponding to the target reference signal resource set, users can indirectly confirm whether the target reference signal resource set is a jointly processed reference signal resource set.

[0087] For example, in one embodiment of this application, the network device sends a set of reference signals to the terminal device. The set of reference signals sent corresponds to the center frequency fc transmitted by the system. At this time, the preset frequency condition is that when fc is greater than the frequency f, the terminal device determines the received set of reference signals as a set of reference signals for joint processing. Subsequently, the terminal device receives a target set of reference signals and detects the center frequency fc corresponding to the received target set of reference signals. When it is determined that fc is greater than f, the received set of reference signals is determined as a set of reference signals for joint processing. Conversely, when it is determined that fc is less than f, the received set of reference signals will not be determined as a set of reference signals for joint processing.

[0088] It should be noted that the preset frequency can be set according to actual needs, and is not limited to determining the target reference signal resource set as the joint processing reference signal resource set when fc is greater than f as provided in the embodiments of this application. It can be fc equal to f, fc less than f, etc. The value of the preset frequency f can be set according to actual conditions. This application does not limit the setting of the preset frequency conditions.

[0089] Step S103b: If the sequence used by the reference signal resource in the target reference signal resource set belongs to the preset sequence set, the reference signal resource is determined as the reference signal resource to participate in the joint processing, and the reference signal resources determined to participate in the joint processing are combined into a joint processing reference signal resource set.

[0090] Associating the measurement results of the reference signal resource set with the sequence used by the reference signals in the target reference signal resource set allows the terminal device to indirectly confirm whether the reference signals in the target reference signal resource set need to be combined into a joint processing reference signal resource set by detecting the sequence used by the reference signals.

[0091] For example, in one embodiment of this application, a network device sends a set of reference signal resources to a terminal device. The sequence used by the reference signals in the set of reference signal resources is 's', and a preset sequence set is 'S'. After receiving the set of reference signal resources, the terminal device determines whether the sequence used by the reference signals belongs to the preset sequence set. In an exemplary embodiment, the terminal device receives a target set of reference signal resources sent by the network device. The target set of reference signal resources includes reference signal 1, reference signal 2, and reference signal 3. Reference signal 1 uses sequence s1, reference signal 2 uses sequence s2, and reference signal 3 uses sequence s3. The user determines whether s1, s2, and s3 belong to S, for example, s1, s2 ∈ S. Reference signal 1 and reference signal 2 are combined to determine the joint processing reference signal resource set, while reference signal 3 is not combined to determine the joint processing reference signal resource set.

[0092] It should be noted that, in this application embodiment, multiple sequence sets S1, S2, S3, etc., can be preset. When the user receives multiple reference signals, the sequence used by each reference signal is obtained, and the reference signals are grouped according to the preset sequence set to which each sequence belongs. The reference signals in the same group can form a joint processing reference signal resource set. This application does not limit the setting of the preset sequence set.

[0093] Step S103c: If the total time occupied by all reference signal resources in the target reference signal resource set meets the preset time condition, the target reference signal resource set is determined to be the joint processing reference signal resource set.

[0094] By associating the measurement results of the reference signal resource set with the time occupied by all reference signal resources in the target reference signal resource set, users can indirectly confirm whether the target reference signal resource set needs to be determined as a joint processing reference signal resource set by detecting the reception time.

[0095] For example, in one embodiment of this application, the network device sends a set of reference signals to the terminal device. The time required for the terminal device to detect and receive all the reference signals in the set of reference signals is t. When t is less than or equal to a preset time T, the received set of reference signals is determined as a set of reference signals for joint processing. Otherwise, when t is greater than T, the received set of reference signals will not be determined as a set of reference signals for joint processing.

[0096] For example, in another embodiment of this application, it is assumed that the network device sends N reference signals, the time required for the terminal device to detect and receive all N reference signals is t, and the time required for the terminal device to receive and detect the first n reference signals is tn. n When t is greater than T, the terminal device divides the k reference signals into groups according to time sequence, and the reference signals within each group are jointly processed, assuming that t satisfies n The maximum value of n under the condition ≤T is n max , k≤n max .

[0097] It should be noted that the preset duration in this application embodiment can be set according to actual needs. In addition to t being less than or equal to T provided in this application embodiment, the preset time condition can also be set to t being greater than T, t being less than T, etc. This application does not limit the setting of the preset duration and preset time condition.

[0098] Step S103d: If the number of reference signal resources contained in the target reference signal resource set meets the preset quantity condition, the target reference signal resource set is determined to be a joint processing reference signal resource set.

[0099] Whether the measurement results of the reference signal resource set are jointly processed is related to the number of reference signals in the received target reference signal resource set. By using the number of reference signals, users can indirectly confirm whether the target reference signal resource set needs to be determined as a joint processing reference signal resource set.

[0100] For example, in one embodiment of this application, the network device sends a set of reference signals to the terminal device. The terminal device detects and receives all reference signals in the set of reference signals. Assuming that the total number of reference signals in the set of reference signals is N, when N is less than a preset number K, the received set of reference signals is determined as a set of reference signals for joint processing. Conversely, when N is greater than K, the received set of reference signals will not be determined as a set of reference signals for joint processing.

[0101] It should be noted that the preset quantity setting in this application embodiment can be set according to actual needs. In addition to N being less than K provided in this application embodiment, the preset quantity condition can also be set to N being greater than K, N being less than or equal to K, etc. This application does not limit the setting of the preset quantity and the preset quantity condition.

[0102] For example, in another embodiment of this application, when N is greater than a preset number K, the terminal device divides every n reference signals into a group according to the receiving time order, and the measurement results of the reference signals in the same group are jointly processed, wherein n≤K.

[0103] The joint processing reference signal resource set is determined implicitly. The reference signal resource set sent by the network device does not need to carry indication information. The terminal device directly determines the joint processing reference signal resource set based on the information associated with the target reference signal resource set.

[0104] After determining the set of reference signal resources for joint processing, the measurement results of the reference signals corresponding to the set of reference signal resources for joint processing are obtained, and the measurement results of the reference signals are jointly processed. For the relevant process, please refer to steps S201 to S202 mentioned above, which will not be repeated here.

[0105] It should be noted that, in this embodiment, in step S202, multiplying the measurement results corresponding to all reference signals with the joint processing matrix to obtain the joint processing result, the joint processing matrix can be configured by the network device to the terminal device, and the method for obtaining the joint processing matrix can include, but is not limited to:

[0106] Obtain the sequences used by each reference signal in the joint processing reference signal resource set, and construct a joint processing matrix based on the sequences;

[0107] Obtain sequence indices from each reference signal in the joint processing reference signal resource set, obtain the corresponding sequences based on the sequence indices, and construct a joint processing matrix based on the sequences;

[0108] Receive downlink signaling, obtain the matrix index from the downlink signaling, and obtain the joint processing matrix based on the matrix index;

[0109] Receive downlink signaling, determine matrix elements based on the bit map contained in the downlink signaling, and construct a joint processing matrix based on the matrix elements.

[0110] It should be noted that, in this embodiment, the network device can transmit the joint processing matrix to the terminal device by including it in the downlink reference signal, or by directly notifying the terminal device via signaling. Alternatively, multiple joint processing matrices can be pre-configured on both the network device and the terminal device side. When joint processing is required, the network device instructs the terminal device to use the appropriate joint processing matrix. The terminal device then completes the joint processing of the reference signal measurement results using the joint processing matrix.

[0111] The joint processing of the reference signal measurement results is linear. For example, in the embodiments of this application, the joint processing can be represented by a processing matrix W, where W is an N*M dimensional matrix. By arranging the N measurement results into a vector y and multiplying it by the processing matrix W, an M-dimensional processing result can be obtained. The combined processing results are as follows:

[0112] After the measurement results are jointly processed to obtain the processed result, it needs to be reported. In this embodiment of the application, reporting the joint processing result may include:

[0113] (1) When there is only one joint processing result, determine the L elements with the largest modulus in the joint processing result, and report the quantization value of these L elements and the index corresponding to these L elements.

[0114] For example, in one embodiment of this application, if only one joint processing result is obtained, the joint processing result is: As shown in the previous section, the user determines the L elements with the largest modulus values ​​in the combined processing results. It also reports the quantization values ​​of the L elements with the largest modulus values, and their corresponding indices m1, m2, ..., m. L .

[0115] (2) When there is only one joint processing result and there is also an unprocessed reference signal measurement result, the joint processing result and the unprocessed reference signal measurement result are combined into a target vector, the largest L elements in the target vector are determined, and the quantization value of these L elements and the index corresponding to these L elements are reported.

[0116] For example, in one embodiment of this application, the number of joint processing results is only one, and the joint processing result is... Furthermore, there are multiple unprocessed measurement results y = [y1 y2 ... y n ] T At this point, the joint processing results and the unjoint processing measurement results are combined into a target vector. Target vector as follows:

[0117] The terminal device reports the target vector. The quantization values ​​of the top L elements with the largest modulus values ​​and the indices of these L elements.

[0118] (3) When there are multiple joint processing results, combine the multiple joint processing results into a target vector, determine the L elements with the largest modulus in the target vector, and report the quantization values ​​of the L elements and the indices corresponding to the indices of the L elements.

[0119] For example, in one embodiment of this application, there are multiple combined processing results, such as It is necessary to combine the results of multiple joint processing into a target vector. Target vector as follows:

[0120] The terminal device reports the target vector. The quantization values ​​of the top L elements with the largest modulus values ​​and the indices of these L elements.

[0121] (4) When there are multiple joint processing results, obtain the measurement results of the reference signal corresponding to the joint processing results, combine all the joint processing results into a target vector, determine the L elements with the largest magnitude in the target vector, and report the quantization values ​​of the L elements and the indices corresponding to these L elements.

[0122] For example, in one embodiment of this application, there are multiple combined processing results, such as In addition, there are multiple unprocessed measurement results y = [y1 y2 ... y n ] T At this point, it is necessary to combine all the joint processing results and all the measurement results into a target vector. Target vector as follows:

[0123] The terminal device reports the target vector. The quantization values ​​of the top L elements with the largest modulus values ​​and the indices of these L elements.

[0124] It should be noted that in this embodiment, the quantity L is an integer greater than 1, which can be configured by the network device to the terminal device.
