[0003] Currently, the channel state information (CSI) measurement reporting method of new radio (NR) is based on downlink reference signal measurement. In the 6G system, network deployment will be more flexible, such as not only providing services for user equipment (UE) by network equipment, but also providing services for other UEs by UEs. Multiple transmission reception points (TRPs) in a cell (or multiple cells) can simultaneously perform downlink transmission or simultaneously perform uplink transmission. Therefore, there are not only same-link interference, such as downlink transmission interference on downlink transmission and uplink transmission interference on uplink transmission, but also cross-link interference in the system.

[0099] In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the present disclosure.

[0100] The term "and / or" in the embodiments of the present application describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0101] In the related art, the CSI measurement reporting method of NR is based on the measurement of the downlink reference signal.

[0102] The UE performs measurement reporting according to the configuration of the report setting, and each report setting is associated with one or more CSI resource settings.

[0103] If the network side (i.e., the network-side device) configures one CSI resource setting, the CSI resource setting is used for channel measurement (L1-RSRP) or channel measurement and interference measurement (L1-SINR), wherein L1-RSRP represents Layer 1 Reference Signal Received Power, and L1-SINR represents Layer 1 Signal to Interference plus Noise Ratio.

[0104] If the network-side device configures two CSI resource settings, the first CSI resource setting is used for channel measurement, and the second CSI resource setting is used for interference measurement based on Channel State Information-Interference Measurement (CSI-IM) or Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS);

[0105] If the network side device configures 3 CSI resource settings, the first CSI resource setting is used for channel measurement, the second CSI resource setting is used for interference measurement based on CSI-IM, and the third CSI resource setting is used for interference measurement based on NZP CSI-RS.

[0106] For periodic and semi-persistent CSI resource settings, one or 2 CSI resource sets can be configured, each of which is associated with a TRP; for aperiodic CSI resource settings, one or more resource sets can be configured, but at most 2 CSI resource sets can be triggered by one DCI, each of which is associated with a TRP.

[0107] In summary, the UE performs measurement reporting according to the reporting configuration, and the network side device configures different numbers of CSI resource settings, each of which has different purposes. At the same time, different types of CSI resource settings have corresponding rules in terms of resource set configuration, association with TRP, and DCI triggering of aperiodic CSI resource sets. For example, when the network side device configures one CSI resource setting, it can be used for channel measurement such as L1-RSRP, or for both channel measurement and interference measurement such as L1-SINR. For another example, for aperiodic CSI resource settings, although multiple resource sets can be configured, at most 2 CSI resource sets can be triggered by one DCI.

[0108] In related technologies, the CSI measurement reporting method of NR is based on downlink reference signal measurement. In the 6G system, network deployment will be more flexible, such as not only providing services for user equipment (UE) by network devices, but also providing services for other UEs by UEs. Multiple transmission reception points (TRPs) in a cell (or multiple cells) can simultaneously perform downlink transmission or simultaneously perform uplink transmission. Therefore, there are not only same-link interference, such as downlink transmission interference on downlink transmission and uplink transmission interference on uplink transmission, but also cross-link interference. However, the current measurement reporting method is only applicable to downlink channel measurement or downlink interference related measurement reporting, so the information of the measurement reporting is very limited.

[0109] To solve the above problems, some embodiments of the present disclosure propose a measurement reporting method, in which a measurement terminal can determine a measurement reference signal according to the configuration of a network side device or a predefined rule, the measurement reference signal including an uplink reference signal and / or a downlink reference signal, and then determine the reception timing of the measurement reference signal and / or the measurement time window according to the predefined rule, and then perform measurement reporting.

[0110] For example, in practical applications, if the receiving timing of the measurement reference signal and the measurement time window are not explicitly measured, it is easy to cause deviation of the measurement result, such as introducing the measurement result of other channels or signals except the reference signal when performing channel measurement or interference measurement. For another example, only when the measurement reference signal is accurately determined, can a basis for subsequent accurate measurement and reporting be laid.

[0111] In some embodiments of the present disclosure, the measurement terminal can be a wireless terminal, which can be a device providing voice and / or other service data connectivity to a user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN), and can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket, handheld, built-in computer or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network. The wireless terminal can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, which are not limited herein.

[0112] In some embodiments of the present disclosure, the network side device can include a terminal device or an access network device serving the measurement terminal. The access network device can include, but is not limited to, various types of base stations, relay points, or access points, etc. The base station can be a base station (BTS) in Global System of Mobile communication (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved base station (eNB) in Long Term Evolution (LTE), or a base station in 5G network, etc.

[0113] For example, FIG. 1 is a flowchart of a measurement reporting method. As shown in FIG. 1, the method can include, but is not limited to, the following steps:

[0118] The reception timing can be a preset time at which the measurement reference signal is received, i.e., the start time of receiving the measurement reference signal.

[0119] The (1) and (2) above can determine a unified receiving timing for the measurement reference signal. For example, all measurement resources in a measurement resource set use a unified (i.e., same) timing for receiving, such as the uplink measurement resource set uses the uplink timing for receiving, when there are multiple timings (e.g., time advance) in the uplink, the uplink measurement resource set uses the first uplink timing for receiving; or the downlink measurement resource set (CSI-RS resource set) uses the downlink timing for receiving; or all measurement resources in all measurement resource sets (including the channel measurement resource set, the interference measurement resource set, etc., the measurement resource set corresponding to one transmission point, the measurement resource set corresponding to multiple transmission points, the uplink measurement resource set, the downlink measurement resource set, etc.) use a unified timing for receiving, which can be the first downlink timing or the second uplink timing. The uplink measurement resource set above can be a sounding reference signal (SRS) resource set.

[0120] The measurement time window above can be a preset time length for measurement, such as the time length can be one time slot, one symbol, one resource element (RE), or a signal part in one symbol except the cyclic prefix (CP) part. The measurement time window affects the time length in power calculation.

[0121] 102. The measurement terminal measures the measurement reference signal according to the receiving timing and / or the measurement time window to obtain the reporting content. The reporting content here is the content to be reported to the network device.

[0186] a received power of the interference measurement reference signal or a signal-to-interference-and-noise ratio corresponding to the measurement reference signal, determined based on a time proportion or a time length of the second portion of the interference measurement reference signal;

[0187] a received energy of the interference measurement reference signal and a time proportion of the second portion of the interference measurement reference signal;

[0188] a signal-to-interference-and-noise ratio corresponding to the measurement reference signal and a time proportion of the second portion of the interference measurement reference signal;

[0189] a received energy of the interference measurement reference signal and a time length of the second portion of the interference measurement reference signal;

[0190] a signal-to-interference-and-noise ratio corresponding to the measurement reference signal and a time length of the second portion of the interference measurement reference signal;

[0191] a received power of the interference measurement reference signal and a time proportion of the second portion of the interference measurement reference signal;

[0192] a received power of the interference measurement reference signal and a time length of the second portion of the interference measurement reference signal;

[0193] a received power of the interference measurement reference signal and a third time difference, the third time difference being a time difference between a reception time of the interference measurement reference signal and the reception timing;

[0194] a signal-to-interference-and-noise ratio corresponding to the measurement reference signal and the third time difference;

[0195] a received energy of the interference measurement reference signal and the third time difference;

[0196] a reception power of the interference measurement reference signal and the fourth time difference, the fourth time difference being a time difference between a reception time of the interference measurement reference signal and the reception timing;

[0197] a signal-to-interference-and-noise ratio corresponding to the measurement reference signal and the fourth time difference;

[0198] a reception power of the interference measurement reference signal and the fourth time difference.

[0199] 103、The measurement terminal sends the reporting content to the network side device.

[0200] The above reporting method, the measurement terminal can determine the reception timing and / or the measurement time window, and measure the measurement reference signal according to the reception timing and / or the measurement time window to obtain the reporting content, and send the reporting content to the network side device; wherein the measurement reference signal includes: uplink reference signal and / or downlink reference signal. In this method, since the measurement reference signal includes the uplink reference signal and / or the downlink reference signal, after the measurement terminal determines the reception timing and / or the measurement time window, the uplink reference signal and / or the downlink reference signal can be measured, so that the reporting content includes the measurement content of the uplink reference signal and / or the downlink reference signal, so that more flexible channel information and / or interference information can be measured, and the information of the measurement reporting is enriched.

[0201] In the reporting content, the following reporting quantities can be reported to reflect the results of channel measurement and / or interference measurement:

[0202] 1) The first type: the channel measurement result based on the channel measurement reference signal.

[0203] The channel measurement reference signal can include: channel measurement SRS, or channel measurement CSI-RS.

[0204] For example, the following is described based on the channel measurement reference signal as the channel measurement SRS.

[0205] In the channel measurement based on SRS (i.e. the above channel measurement SRS), the network side device can only configure the SRS related measurement resource for the UE. Among them, the SRS can be sent by other UEs, such as other UEs as the cooperative transmission point of the measurement UE. The measurement quantity or the reporting quantity can be the resource indication of SRS (SRS RI) and / or the reception power of SRS (L1-SRS-RSRP).

[0206] In this case, the SRS sent by other UEs and the basic timing of the measurement UE can not be the same. For example, the measurement UE is not connected to the UE sending SRS at this time, and can only be connected to the TRP of downlink transmission or the UE of uplink transmission of other SRS.

[0207] In addition, the number of SRSs configured in the measurement report can be greater than 1, such as corresponding to multiple UEs. At this time, the behavior of the UE measuring the SRS needs to be constrained to ensure the comparability of multiple measurement results, and the method of determining the reception timing corresponding to the channel measurement SRS includes but is not limited to the following methods.

[0208] Method 1: Measuring multiple SRSs or SRS sets by a unified downlink related timing or time window.

[0209] When the UE transmits, it receives a downlink signal using at least one downlink related timing and transmits an uplink signal using at least one uplink related timing. In this scheme, the UE measures multiple SRSs or SRS sets using a downlink related timing or a downlink related time window.

[0210] In some embodiments, when the channel measurement reference signal is a channel measurement SRS, the transmission interval between the transmission of the channel measurement SRS and other signals has a preset time length, and the other signals are signals used for channel measurement other than the channel measurement SRS, or signals used for interference measurement.

[0211] In the above embodiments, by having a preset time length, other signals before or after the channel measurement SRS can be avoided from being introduced into the measurement time window, thereby causing a large deviation in the measurement result and affecting the performance and stability of the entire communication system.

[0212] For example, as shown in FIG. 2, FIG. 2 is a schematic diagram of a UE receiving (i.e., downlink reception timing) and measuring different SRSs by means of a downlink related timing. In FIG. 2, in order to ensure the accuracy of SRS measurement, a certain time gap (gap) is left between the SRS and other signals used for channel measurement or signals used for interference measurement transmitted by the UE when the SRS is transmitted, i.e., a preset time length, so as to prevent the UE from calculating the reception power of other channels or signals into the reception power related to the SRS when measuring. As shown in FIG. 2, SRS1 and SRS2 represent different SRSs, and there is a certain gap between them. Since when receiving by using a unified downlink related timing, the channels or signals before or after the SRS can be introduced into the measurement time window, a certain gap is left before the SRS is transmitted and a certain gap is also left after the SRS is transmitted.

[0213] In actual communication scenarios, if no gap as shown in FIG. 2 is reserved, it is easy to cause a large deviation in the SRS measurement result, thereby affecting the performance and stability of the entire communication system.

[0214] The determination method of the first part corresponding to the channel measurement SRS can include but is not limited to any one of the following:

[0215] The resource part in the symbol corresponding to the channel measurement SRS except the CP.

[0216] From the symbol corresponding to the channel measurement SRS, the resource part determined according to the reception timing and / or the reception time window;

[0217] From the symbol corresponding to the channel measurement SRS, the resource part determined according to the reception timing and / or the reception time window, excluding the CP;

[0218] The resource part of the symbol corresponding to the channel measurement SRS (i.e. the part of the symbol corresponding to the channel measurement SRS including the CP).

[0219] The resource part can include but is not limited to any one of the following: sample, symbol, RE.

[0220] In NR, the received power measured in the measurement of CSI-RS is the power of the first part excluding the CP part.

[0221] When measuring SRS, the first part of SRS can only account for a part of the length of the received symbol except the CP part. Taking SRS1 in FIG. 2 (only for illustrative purposes, multiple SRSs are not transmitted on the same symbol, or when the transmission symbols do not overlap, it is also applicable) as an example, within the measurement window of one symbol length, the proportion of the first part excluding the CP is less than 1. If the UE only reports the received signal power to the network side device, it may not reflect the true measurement level of the SRS1. In order to ensure the comparability of the measurement (such as channel measurement) of different SRSs, it is also necessary to report the proportion of the first part (i.e. the time proportion of the above first part).

[0222] For example, the UE uses the sequence of SRS1 to perform autocorrelation with the received signal, and determines the transmission symbol of SRS1 according to the position and / or received energy of the correlation peak, such as the part in the measurement time window in FIG. 2.

[0223] The UE reporting content corresponding to the above channel measurement SRS can include but is not limited to one or more of the following options:

[0224] Option 1: UE reports the received power of SRS, and the received power is calculated by the UE based on the time proportion or time length of the determined first part.

[0225] In this method, the UE can calculate the time proportion of the first part, which is the time proportion of the first part after removing the gap and removing the CP length. In FIG. 2, the gap of SRS1 is behind the reception of the SRS symbol, so it can be determined that the received SRS signal part does not contain CP, and the gap of SRS2 is before the reception of the SRS symbol, so it can be determined that the received SRS part contains CP, and when calculating the proportion or length of the first part, the CP length also needs to be removed.

[0226] From the perspective of the received power of the first part, the UE reports according to option 1, and the network side device can determine the received power of the SRS according to the UE report.

[0227] Option 2: The UE reports the received energy of the SRS and the time length or time proportion of the first part.

[0228] The above option 2 is actually equivalent to option 1, and the network side device can calculate the received power of the SRS by itself after receiving the received energy and the time length (or time proportion) of the first part. Through the reporting of the time length of the first part and the time proportion of the first part, the network side device can also determine how large the overlap between SRS transmission and CSI-RS transmission is, or determine how large the timing difference between CSI-RS and SRS is.

[0229] Option 3: The UE reports the received power of the SRS and the time length or time proportion of the first part.

[0230] The above option 3 is similar to option 2. Among them, the received power of the SRS can be calculated based on the time length or time proportion of the first part reported by the UE.

[0231] Option 4: The UE reports the received power or received energy of the SRS and the time difference of the SRS compared to the downlink reception timing.

[0232] Among them, the above downlink reception timing can refer to the downlink related timing used for reception.

[0233] The above time difference can be positive or negative. The positive value indicates that the reception time of the SRS is after the downlink reception timing, as shown in SRS2 in FIG. 2; the negative value indicates that the reception time of the SRS is before the downlink reception timing, as shown in SRS1 in FIG. 2.

[0234] In addition, the network side device can also determine whether the CP length is included in the time difference according to whether the time difference fed back by the UE is positive or negative.

[0235] Option 5: The UE reports the received power or received energy of the SRS and the time difference of the SRS compared to the downlink reception timing except for the CP.

[0236] In some embodiments of the present disclosure, the reporting of the first part of the time length in option 5 is essentially the same as that in option 3, and there is a certain difference in reporting the time ratio of the first part in option 3.

[0237] When receiving the SRS, due to the use of downlink related timing, according to the related art, the UE needs to first remove the CP in the signal within a symbol, and then perform fast Fourier transform (FFT) processing, etc. Since each SRS in the measurement time window may or may not contain a CP, even if it contains a CP, the position of the CP is different from that of the downlink signal. Therefore, in the SRS measurement, there is no need to remove the CP from the SRS, or the UE processes each SRS separately according to the position of the CP. For example, if the SRS contains a CP, the CP is removed; if the SRS does not contain a CP, there is no need to remove the CP, and the measurement is directly performed.

[0238] In addition, since there is a certain gap between the SRS and other signals during transmission, the influence of inter-symbol interference is small, and all SRSs can not be subjected to CP removal processing. Even if the time window contains the CP part of a certain SRS, it can be directly used to measure the received signal power of the SRS.

[0239] If there is no gap between the SRS signal and other signals or channels, the UE also needs to determine the reception time of the SRS according to the autocorrelation characteristics of the SRS, and then measure the first part of the SRS. For example, the CP of the SRS is removed, other signals are removed, and only the first part is used to determine the received power of the SRS.

[0240] According to the method in the above manner 1, the UE does not need to add a new timing for SRS reception, and can complete the downlink signal reception and SRS signal reception using one or more sets of downlink reception timing.

[0241] Manner 2: Measure the configured multiple SRSs or SRS sets, etc. through a unified uplink related timing (or at least one timing corresponding to the SRS).

[0242] Assuming there is a gap between the SRS and other signals when the SRS is transmitted, the UE can select the timing corresponding to at least one SRS for receiving when receiving the SRS. FIG. 3 is a schematic diagram of a UE selecting the receiving timing corresponding to SRS1 for receiving and measuring all SRSs. In FIG. 3, the UE selects the receiving timing corresponding to SRS1 for receiving and measuring all SRSs (including SRS1, SRS2 and SRS3 in FIG. 3). For example, the UE can determine which SRS signal arrives earliest by detecting the received signal strength. For another example, the UE can first buffer the resources corresponding to each SRS, and then determine a unified measurement time window for detecting and measuring the SRSs.

[0243] Compared with the above-described manner 1, the manner 2 is more complex to process. First, in the manner 1, the start time of the measurement time window is the downlink receiving timing, and thus the measurement time window is fixed for the UE. In the manner 2, the UE needs to first determine a unified time window, such as the time window determined according to the received signal strength as mentioned above. The UE can also feed back the SRS index corresponding to the selected measurement time window or measurement timing to the network side device, and when the network side device wants the UE to focus on measuring a certain SRS, such as measuring SRS2 in FIG. 3, the network side device can also configure the UE to perform measurement and report of each SRS or SRS set according to the receiving timing of SRS2. The measurement according to the receiving timing of SRS2 can ensure that the reference signal part corresponding to SRS2 can be measured.

[0244] The various measurement and reporting methods in the above-described manner 1 can be used in the manner 2, for example, the various methods shown in options 1 to 5 in the above-described manner 1 can be included in the above-described manner 2.

[0245] Manner 3: Each SRS or SRS set uses different receiving timing and / or measurement time window for measurement. The receiving timing includes uplink-related timing or downlink-related timing.

[0246] The manner 3 is different from the above-described manner 1 and manner 2, and each SRS can be received according to the respective timing or measurement time window, which can ensure that the first part of each SRS can be measured. In this way, the UE does not need to report the first part corresponding to the received power or received energy of each SRS, and at this time, the first part is fixed, that is, the symbol part excluding the CP.

[0247] Through the first reporting scheme, the network side device can determine the received signal strength of the SRS, and further determine whether the terminal corresponding to the SRS can measure the UE serving. Alternatively, the network side device can also determine whether the uplink transmission corresponding to other TRPs can be performed simultaneously with the downlink transmission of the measurement UE according to the received signal strength of the SRS. A specific threshold can also be set for the SRS received power. When the SRS received power reaches the threshold value, the UE will report the corresponding SRS index and / or received power value.

[0248] 2) The second type: based on the measurement results of the channel measurement reference signal and the interference measurement reference signal.

[0249] The above-mentioned second type can include the following two cases:

[0250] The first case: SRS related interference measurement results, in which SRS is used for channel measurement, and other signals are used for interference measurement;

[0251] The second case: SRS as the interference measurement result corresponding to other signals.

[0252] In order to more clearly illustrate the method provided by some embodiments of the present disclosure, the above two cases will be introduced respectively.

[0253] For the above-mentioned first case:

[0254] In the reporting scheme of the first case in the above-mentioned second type, SRS is used for channel measurement, and other reference signals (CSI-RS or other SRS) are used for interference measurement. The measurement quantity or reporting quantity can be a large-scale related interference measurement quantity, such as L1-SRS-SINR, and can also be a small-scale channel corresponding interference measurement quantity, such as channel quality indicator (CQI) based on SRS, etc.

[0255] If the network side device configures the UE to measure the interference of SRS on CSI-RS or SSB, it is necessary to determine how to determine the reception according to which timing. The following measurement scheme can be considered:

[0256] Method 4: receiving SRS according to the timing of SRS, and receiving downlink reference signals according to the downlink related timing (such as CSI-RS timing).

[0257] In actual signal transmission, whether the uplink and downlink related timings are aligned or not, the interference of the downlink always exists in the uplink reference signal receiving process, which can be measured in the transmission process of the SRS.

[0258] The above-mentioned receiving SRS according to the receiving timing of SRS can ensure that SRS is accurately measured.

[0259] The time length of the SRS and the downlink reference signal can be the same or different. FIG. 4 is a schematic diagram of the time length of the two reference signals. In FIG. 4, only the case where the SRS and the CSI-RS are transmitted in different symbols is shown, and the case where the symbols are not overlapped is also applicable. For example, the SRS is transmitted in symbol n (i.e., the nth symbol), and the CSI-RS is transmitted in symbol n+4. In (a) of FIG. 4, the time window of the CSI-RS is smaller than the time window of the corresponding SRS. In (b) of FIG. 4, the time window length of the CSI-RS and the SRS can be the same. In fact, the time length of the received power and the reference signal is irrelevant, and both of the two cases shown in FIG. 4 can work in theory, as long as the measured signal energy or interference energy is aligned with the corresponding time length.

[0260] The measurement of the downlink reference signal needs to meet one or more of the following conditions, including but not limited to:

[0261] Condition 1: The second part of the interference measurement reference signal is measured according to the downlink related timing.

[0262] For example, the second part of the interference measurement reference signal is any one of the following:

[0263] The resource part in the symbol corresponding to the downlink reference signal, excluding the CP;

[0264] The overlapping part in the symbol corresponding to the downlink reference signal and the symbol corresponding to the SRS;

[0265] The resource part in the symbol corresponding to the downlink reference signal, determined according to the reception timing and / or the measurement time window;

[0266] The resource part in the symbol corresponding to the downlink reference signal, determined according to the reception timing and / or the measurement time window, excluding the CP;

[0267] The resource part in the symbol corresponding to the downlink reference signal, determined according to the reception timing and / or the measurement time window of at least one SRS;

[0268] The resource part in the symbol corresponding to the downlink reference signal, determined according to the reception timing and / or the measurement time window of at least one SRS, excluding the CP.

[0269] The overlapping part can be the part of the symbol corresponding to the downlink reference signal, excluding the CP, which overlaps with the symbol corresponding to the SRS.

[0270] Condition 2: Even if the CSI-RS and the SRS are transmitted in different symbols, it can be assumed that the CSI-RS is shifted to the symbol where the SRS is located.

[0271] For example, assuming the CSI-RS in FIG. 3 has removed the impact of the CP, only part of the CSI-RS samples are used to measure the interference. In this case, when reporting the signal to interference plus noise ratio (SINR) or CQI, the UE can also report the time length or time proportion of the interference measurement, similar to the first type of reporting.

[0272] Condition 3: The CSI-RS is measured using the receive beam or corresponding transmit beam (such as specific QCL parameters, TCI state, beam index, etc.) of the SRS.

[0273] Method 5: The SRS is received according to the downlink-related timing, and the downlink reference signal is received according to the downlink-related timing (such as the CSI-RS timing).

[0274] In method 5, the UE can be in downlink transmission, and the UE can use a unified downlink UE timing for the reception and measurement of each reference signal.

[0275] At this time, the measurement of the receive power corresponding to the CSI-RS is similar to the related art, and the measurement of the SRS needs to determine the time proportion or time length of the second part according to the first type of reporting, and then correctly determine the receive power of the second part of the SRS.

[0276] In this method, the CSI-RS is measured using the receive beam or corresponding transmit beam (such as specific QCL parameters, beam index, etc.) of the SRS.

[0277] Method 6: The SRS is received according to the timing of the SRS, and the downlink reference signal is received according to the timing of the SRS.

[0278] At this time, it can be ensured that the second part of the SRS excluding the CP can be received, but the time proportion or time length of the second part of the CSI-RS needs to be determined by the UE. In some embodiments of the present disclosure, the UE reports the time proportion or time length of the second part to the network side device.

[0279] In this method, the CSI-RS is measured using the receive beam or corresponding transmit beam (such as specific QCL parameters, beam index, etc.) of the SRS.

[0280] If the network side device instructs the UE to measure the interference of SRS2 to SRS1, method 6 above can be used for measurement, such as using the timing of SRS1 to receive SRS2, and as for the receive beam or transmit beam, the SRS2 is measured using the receive beam or corresponding transmit beam (such as specific QCL parameters, beam index, etc.) of SRS1.

[0281] The second case: SRS as interference of other signals corresponds to interference measurement results.

[0282] In the reporting scheme of the second case in the second type, SRS is used for interference measurement, and other reference signals (CSI-RS or other SRS) are used for channel measurement. The measurement quantity or the reported quantity can be a large-scale related interference measurement quantity, and can also be a small-scale channel corresponding interference measurement quantity.

[0283] In some embodiments, the reception timing of SRS can be determined according to the channel measurement reference signal. For example, when the channel measurement reference signal is CSI-RS or SSB, the SRS can be received and measured using the downlink related timing; when the channel measurement reference signal is SRS, the SRS can be received and measured using the reception timing of the channel measurement SRS.

[0284] In some embodiments, when SRS is used as interference, the interference measured by the UE based on SRS is only cross-link interference, and can not be all interference. For example, there is also other inter-cell interference in the downlink transmission of the UE, and therefore, CSI-IM can also be used for joint SRS interference measurement reporting.

[0285] In some embodiments of the present disclosure, when performing measurement reporting, the type of measurement reference signal can be used to determine which type of measurement reporting is performed.

[0286] For example, when SRS is configured in the channel measurement reference signal, and no interference measurement resource is configured, or SRS is configured for channel measurement and no interference measurement resource is configured, the UE determines to perform the measurement reporting of the first type described above.

[0287] For another example, when SRS is configured in the channel measurement reference signal, and interference measurement resource is configured, or SRS is configured for channel measurement and interference measurement resource is configured, the UE determines to perform the measurement reporting of the first case in the second type described above.

[0288] For another example, when SRS is configured in the interference measurement reference signal, or SRS is configured for interference measurement, the UE determines to perform the measurement reporting of the second case in the second type described above.

[0289] In addition, the type of measurement reporting can also be distinguished by the configuration of the reported quantity. For example, the network side device configures the UE to perform layer 1 SRS-based RSRP measurement reporting (such as L1-SRS-RSRP reporting), and the UE determines to perform the measurement reporting of the first type described above, that is, SRS is used for channel measurement.

[0290] For example, if the network side device configures the UE to perform the layer 1 SRS-based SINR measurement report (such as L1-SRS-SINR report), the UE determines to perform the measurement report in the first case in the second type, that is, the SRS is used for channel measurement, and other signals are used for interference measurement.

[0291] For example, if the network side device configures the UE to perform the general interference measurement report (such as L1-SINR report), the UE determines to perform the measurement report in the second case in the second type, that is, the SRS is used for interference measurement.

[0292] In some embodiments of the present disclosure, the measurement reference signal can be determined according to the network side device configuration or the pre-defined manner. That is, in some embodiments of the present disclosure, the resource used for measurement report can be determined based on at least one of the following methods:

[0293] Method 1: Pre-defined manner

[0294] If 1 resource setting is configured, the 1 resource setting is used for channel measurement, and the SRS resource set or the CSI-RS resource set can be configured in the resource setting. Regardless of which resource set is configured, it is used for channel measurement.

[0295] If 2 resource settings are configured, the following possible cases are included:

[0296] Case 1: The first resource setting is used for channel measurement, such as CSI-RS-based channel measurement, and the second resource setting is used for interference measurement based on one or more of CSI-IM, NZP CSI-RS and SRS.

[0297] Case 2: The first resource setting is used for channel measurement, such as SRS-based channel measurement, and the second resource setting is used for interference measurement based on CSI-IM or NZP CSI-RS.

[0298] Case 3: The first resource setting is used for channel measurement, such as SRS-based channel measurement, and the second resource setting is used for interference measurement based on SRS.

[0299] If 3 resource settings are configured, the following possible cases are included:

[0300] Case a: The first resource setting is used for channel measurement (such as CSI-RS-based channel measurement), the second resource setting is used for interference measurement based on CSI-IM, and the third resource setting is used for interference measurement based on SRS.

[0301] Case b, the first resource setting is used for channel measurement (such as based on SRS), the second resource setting is based on CSI-IM for interference measurement, and the third resource setting is based on NZP CSI-RS for interference measurement.

[0302] If 4 resource settings are configured, the first resource setting is used for channel measurement (such as based on CSI-RS), the second resource setting is based on CSI-IM for interference measurement, the third resource setting is based on SRS for interference measurement, and the fourth resource setting is based on NZP CSI-RS for interference measurement.

[0303] Method two: network side device configuration

[0304] Due to the introduction of new reference signals, the combination of channel measurement and interference measurement reference signals has become more complex, and the predefined method may not be flexible enough. Therefore, 6G can determine the purpose of each resource setting, such as channel measurement or interference measurement, through network side device configuration, and can also flexibly configure the measurement reference signal under each purpose.

[0305] The above resource settings can include various cases involved in the first method, or other reference signal sets, such as reference signal sets containing multiple resources, and the present application does not limit this.

[0306] In related technologies, the CSI-RS resource used for precoding code word estimation is configured to the UE, such as the SRS resource set for non-codebook transmission is associated with a CSI-RS resource, or is associated with a CSI-RS resource set, wherein the associated CSI-RS resource or CSI-RS resource set is used to determine the precoding code word. When the non-codebook SRS resource set is associated with a CSI-RS resource set, and the CSI-RS resource set contains multiple CSI-RS resources, the multiple CSI-RS resources can be used to correspond to different antenna ports, such as multiple CSI-RS resources jointly construct a large port CSI-RS, at this time, how the terminal determines the precoding code word according to the CSI-RS needs to be clear, otherwise it will cause the precoding code word determined by the terminal and the precoding code word considered by the network side device to be inconsistent, and further cause the transmission performance to decline. For example, for the case of multiple CSI-RS resources constructing a large port CSI-RS resource, taking the number of CSI-RS resources as 4 as an example, if the downlink channel information corresponding to the 4 CSI-RS resources is H1, H2, H3, and H4 respectively. The precoding code word determined by the UE according to [H1 H3 H2 H4] is different from the precoding code word determined according to [H1 H2 H3 H4], and the matching degree with the actual uplink channel is also different.

[0307] Some embodiments of the present disclosure also provide a SRS-based transmission method, which is applied to a terminal and can include but is not limited to the following steps:

[0308] When the non-codebook SRS resource set is associated with multiple CSI-RS resources, the terminal determines a target precoding codebook according to a first mapping order; and the terminal sends a resource in the SRS resource set to the network side device based on the target preset precoding codebook.

[0309] Some embodiments of the present disclosure also provide a SRS-based transmission method, which is applied to a network side device and can include but is not limited to the following steps:

[0310] The network side device receives the SRS resource set sent by the terminal based on the preset precoding codebook.

[0311] The network side device sends an SRS resource indication to the terminal, the SRS resource indication including indication information of at least one SRS resource in the SRS resource set, and the SRS resource indication is used to determine a subsequent precoding codebook.

[0312] The preset precoding codebook is determined according to a first mapping order when the non-codebook SRS resource set is associated with multiple CSI-RS resources.

[0313] Some embodiments of the present disclosure also provide a SRS-based transmission method, which can include but is not limited to the following steps:

[0314] Step 1: When the non-codebook SRS resource set is associated with multiple CSI-RS resources, the terminal determines a target precoding codebook according to a first mapping order.

[0315] The first mapping order includes at least one of the following:

[0316] (A) The CSI-RS resource index of the multiple CSI-RS resources from small to large order and / or the port index of the CSI-RS resource from small to large order corresponds to the calculation of the port of the target precoding codebook.

[0317] For example, each CSI-RS resource is configured with 32 ports, such as port 0-31 of CSI-RS ID 5 corresponding to port 0-31 in precoding codebook calculation, port 0-31 of CSI-RS ID 7 corresponding to port 32-63 in precoding codebook calculation, port 0-31 of CSI-RS ID 9 corresponding to port 64-95 in precoding codebook calculation, and port 0-31 of CSI-RS ID 10 corresponding to port 96-127 in precoding codebook calculation.

[0318] (B) CSI-RS resource configuration order of the plurality of CSI-RS resources and / or port index order of the CSI-RS resources from small to large corresponds to the port of the calculation of the target precoding code word.

[0319] For example, the ports 0-31 of the first configured CSI-RS resource correspond to the ports 0-31 in the calculation of the precoding code word, the ports 0-31 of the second configured CSI-RS resource correspond to the ports 32-63 in the calculation of the precoding code word, the ports 0-31 of the third configured CSI-RS resource correspond to the ports 64-95 in the calculation of the precoding code word, and the ports 0-31 of the fourth configured CSI-RS resource correspond to the ports 96-127 in the calculation of the precoding code word.

[0320] (C) Mapping order configured in the reporting setting in which the plurality of CSI-RS resources are located.

[0321] That is, the mapping order configured in the reporting setting in which the associated CSI-RS resource set is located is the same.

[0322] In the CSI-RS-based measurement reporting, the terminal can also be configured with a mapping relationship between the plurality of CSI-RS resources and the calculation of the precoding code word, at this time, the mapping order configured in the reporting setting can be followed, such as the mapping method 1 and the mapping method 2 mentioned below. At this time, the reporting order configured in the reporting setting can be determined according to the CSI-RS resource or the resource set associated with the SRS resource set, and then the order of the terminal calculating the precoding code word of the SRS is determined.

[0323] (D) A predefined second mapping order.

[0324] The mapping relationship between the CSI-RS resource index (or port index) and the CSI (or PMI) calculation can be determined according to the above-mentioned predefined second mapping order. The PMI refers to a precoding matrix indicator.

[0325] The above-mentioned predefined second mapping order includes but is not limited to at least one of the following mapping method 1 and mapping method 2:

[0326] Mapping method 1: The order / sequence in (the first resource, the first polarization), then (the second resource, the first polarization), …, then (the Kth resource, the first polarization), then (the first resource, the second polarization), then (the second resource, the second polarization), …, then (the Kth resource, the second polarization) is mapped to the PMI.

[0327] Mapping method 2: sequential ordering / indexing within (K*n2=N2)

[0328] For the 1st polarization: (1st n2 port in 1st resource, 1st polarization), (1st n2 port in 2nd resource, 1st polarization), …, (1st n2 port in Kth resource, 1st polarization), then (2nd n2 port in 1st resource, 1st polarization), …, then (2nd n2 port in Kth resource, 1st polarization), …, then (N1th n2 port in 1st resource, 1st polarization), …, then (N1th n2 port in 2nd resource, 1st polarization), …, then (N1th n2 port in Kth resource, 1st polarization), …, then (N1th n2 port in Kth resource, 1st polarization);

[0329] For the 2nd polarization: (1st n2 port in 1st resource, 2nd polarization), then (1st n2 port in 2nd resource, 2nd polarization), …, then (1st n2 port in Kth resource, 2nd polarization), then (2nd n2 port in 1st resource, 2nd polarization), …, then (2nd n2 port in Kth resource, 2nd polarization), …, then (N1th n2 port in 1st resource, 2nd polarization), …, then (N1th n2 port in 2nd resource, 2nd polarization), …, then (N1th n2 port in Kth resource, 1st polarization), …, then (N1th n2 port in Kth resource, 1st polarization) are mapped onto the PMI.

[0330] Where N1 and N2 are high layer signaling configurations, representing the number of antenna ports in horizontal and vertical directions respectively, and n2=N2 / K.

[0331] Step 2, the terminal sends the SRS resource set to the network side device based on the target preset encoding code word.

[0332] Step 3, the network side device receives the SRS resource set sent by the terminal based on the preset encoding code word.

[0333] Step 4, the network side device sends SRS resource indication (SRS Resource Indicator, SRI) to the terminal, the SRS resource indication includes the indication information of at least one SRS resource in the SRS resource set, and the SRS resource indication is used to determine the subsequent precoding code word.

[0334] Through the above SRS-based transmission method, in the case of constructing a large-port CSI-RS for multiple CSI-RS resources, the way of determining the precoding code word according to the CSI-RS can be realized.
