Obviously, the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without any creative effort fall within the scope of protection of the present disclosure.

[0020] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings, which may be used in a wireless communication system, which may be a 5G system, an Evolved Long Term Evolution (eLTE) system, or a subsequent evolution communication system.

[0021] FIG. 1 is a structural diagram of a network system according to an embodiment of the present disclosure. As shown in FIG. 1, the network system includes a terminal 11 and a network side device 12. The terminal 11 may be a mobile communication device, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. The embodiment of the present disclosure does not limit the specific type of the terminal 11. The network side device 12 may be a 5G network side device (e.g., gNB, 5G NR NB), a 4G network side device (e.g., eNB), a 3G network side device (e.g., NB), or a network side device in a later evolution communication system. The embodiment of the present disclosure does not limit the specific type of the network side device 12.

[0022] Before describing the technical solutions of the embodiments of the present disclosure in detail, we first provide a brief introduction to Massive MIMO technology.

[0023] Radio access technology standards such as Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are all based on MIMO + Orthogonal Frequency Division Multiplexing (OFDM) technology, among which MIMO technology utilizes the spatial freedom gained by multi-antenna systems to improve peak data rates and system spectrum utilization.

[0024] With the expansion of the MIMO technology dimension, Rel-8 can support up to four layers of MIMO transmission, Rel-9 will support up to four downlink data layers in the extended MU-MIMO technology and MU-MIMO transmission in Transmission Mode (TM)-8, and Rel-10 will expand the transmission capacity of Single-User MIMO (SU-MIMO) to up to eight data layers.

[0025] Research into next-generation communication systems beyond 4G is increasing the operating frequency bands supported by the systems to above 6 GHz, reaching a maximum of approximately 100 GHz. High-frequency bands have relatively abundant idle frequency resources and can provide greater throughput for data transmission. High-frequency signal wavelengths are shorter, allowing more antenna array elements to be deployed on the same size panel compared to low-frequency bands, and beamforming technology can be used to form more directional, narrower beams. Therefore, it is expected that future 5G mobile communication systems will introduce MIMO technology with larger scales and more antenna ports (i.e., Massive MIMO technology). The use of large-scale antenna arrays can significantly improve the utilization efficiency of system frequency bands and support more access users.

[0026] In Massive MIMO technology, adopting a fully digital array can achieve maximized spatial resolution and optimal MU-MIMO performance, but such a structure requires many AD / DA conversion devices and many complete radio frequency-baseband processing channels, which places a heavy burden on both equipment costs and baseband processing complexity.

[0027] To reduce implementation costs and processing complexity, digital-analog hybrid beamforming technology has emerged. This technology adds a step of beamforming to traditional digital-domain beamforming, using radio frequency signals near the front end of the antenna system. Simulation beamforming is a relatively simple method for achieving a relatively rough match between the transmit signal and the channel. The dimension of the equivalent channel formed after simulation beamforming is smaller than the number of actual antennas, significantly reducing the required AD / DA conversion devices, the number of digital channels, and the corresponding baseband processing complexity. In simulation beamforming, residual interference can be reprocessed in the digital domain to ensure MU-MIMO transmission quality. Compared to full digital beamforming, digital-analog hybrid beamforming offers a trade-off between performance and complexity, and has relatively good practical prospects for systems with high-frequency bands, large bandwidths, or a large number of antennas.

[0028] The simulated beamforming is launched over the entire bandwidth, and each polarization-direction array element on each radio frequency antenna array panel can only transmit a simulated beam in a time-division multiplexing manner. The forming weight value of the simulated beam is achieved by adjusting equipment parameters such as the phase shifter of the radio frequency front-end. Currently, the simulated beamforming vector is generally trained in a polling manner, that is, each polarization-direction array element on each antenna panel transmits a training signal (i.e., a candidate beamforming vector) in turn at a predetermined time in a time-division multiplexing manner. The terminal then feeds back a beam report after measurement, and the network side uses this training signal to launch the simulated beam the next time it transmits a service.

[0029] During beam measurement and selection, the parameter commonly used to measure beam quality is Layer 1 reference signal received power (L1-RSRP). To further improve the accuracy of beam measurement and selection, especially in multi-cell, multi-user, and multi-beam scenarios, a new parameter, L1-SINR, has been introduced. However, when measuring the L1-SINR of a beam, no corresponding solution has been proposed for how to map the CMR and IMR, for example, how to map the correlation between the CMR and IMR, which affects the accuracy of beam measurement and communication reliability of the communication system.

[0030] In view of this, an embodiment of the present disclosure provides a network system as shown in Figure 1, and a resource allocation and measurement method for L1-SINR measurement used in the network system. As shown in Figure 2, the method includes the following steps:

[0031] Step 201: The network side device transmits the configuration information to the terminal.

[0032] Wherein, the configuration information is used to instruct measuring at least a layer 1 signal interference noise ratio (L1-SINR), and the configuration information further includes channel measurement resource (CMR) information and interference measurement resource (IMR) information, and there is a pre-established correlation between the CMR in the CMR information and the IMR in the IMR information.

[0033] Step 202: The terminal receives the configuration information sent by the network side device.

[0034] Step 203: The terminal determines a target CMR and a target IMR for performing target L1-SINR measurement according to the preset association relationship.

[0035] Step 204: The network side device transmits a reference signal for measuring the target L1-SINR based on the configuration information.

[0036] Step 205: Measure the target CMR and the target IMR respectively to obtain the target L1-SINR.

[0037] The order of execution of the above steps 203 and 204 is not limited, and step 203 may be executed first, followed by step 204, or step 204 may be executed first, followed by steps 202 and 203, or step 203 and step 204 may be executed simultaneously.

[0038] In the embodiments of the present disclosure, by presetting the correlation between CMR and IMR for L1-SINR measurement, when a terminal performs L1-SINR measurement, it can select the correct CMR and IMR to perform channel measurement and interference measurement based on the correlation between CMR and IMR, thereby improving the communication reliability of the communication system.

[0039] 3 is a flowchart of a measurement method according to an embodiment of the present disclosure. As shown in FIG. 3, the measurement method is used in a terminal, and the method includes the following steps:

[0040] Step 301: Receive configuration information sent by a network side device, the configuration information being used to instruct measuring at least L1-SINR, the configuration information further including CMR information and IMR information, and there is a pre-established association relationship between the CMR in the CMR information and the IMR in the IMR information.

[0041] Wherein, the configuration information may include information on Channel State Information (CSI) report setting, and the CSI report setting may include measurement report parameters, which may further include L1-RSRP in addition to L1-SINR. That is, the configuration information may be used to instruct measuring L1-SINR, or to instruct measuring L1-SINR and L1-RSRP.

[0042] The configuration information may be Radio Resource Control (RRC) signaling. The configuration information including CMR information may be understood as being capable of configuring at least one RS resource setting (reference signal resource setting) for channel measurement (CM). The configuration information including IMR information may be understood as being capable of configuring at least one RS resource setting for interference measurement (IM). Each RS resource setting may include at least one RS resource set (reference signal resource set), and each RS resource set may include at least one RS resource. In the embodiments of the present disclosure, when the network side device configures to measure the L1-SINR of a beam, it can flexibly configure multiple CMR resource settings and IMR resource settings.

[0043] In the embodiments of the present disclosure, the preset association relationship between the CMR and the IMR may further include multiple association relationships, for example, the association relationship between the CMR and the IMR may be an N-to-N association, a one-to-one association, an N-to-1 association, a one-to-N association, or even no association. The preset association relationship may be relatively flexibly preset, thereby improving the flexibility of L1-SINR measurement.

[0044] The predefined association relationship may be configured by a network-side device, for example, configured in the configuration information, or stipulated by a protocol.

[0045] Step 302: Determine a target CMR and a target IMR for performing target L1-SINR measurement based on the preset correlation.

[0046] In this step, after receiving the configuration information sent by the network side device, the terminal may select a correct target CMR and target IMR to perform target L1-SINR measurement based on a preset correlation between the CMRs and IMRs, where the target CMR is at least one CMR in the CMR information, and the target IMR is at least one IMR in the IMR information.

[0047] Step 303: Measure the target CMR and the target IMR respectively to obtain the target L1-SINR.

[0048] In this step, the terminal measures the target CMR to obtain a target channel measurement result, and the terminal measures the target IMR to obtain a target interference measurement result, and then calculates the target L1-SINR using the target channel measurement result as the numerator and the target interference measurement result as the denominator.

[0049] In the embodiments of the present disclosure, by presetting the correlation between CMR and IMR for L1-SINR measurement, when a terminal performs L1-SINR measurement, it can select the correct CMR and IMR to perform channel measurement and interference measurement based on the correlation between CMR and IMR, thereby improving the communication reliability of the communication system.

[0050] In the embodiment of the present disclosure, the CMR in the CMR information and the IMR in the IMR information may belong to different resource settings, or may belong to different resource sets in the same resource setting.

[0051] When multiple CMRs are configured in a network side device, i.e., when the CMR information includes multiple CMRs, different CMRs in the CMR information belong to different resource settings, or different CMRs in the CMR information belong to the same resource set in the same resource setting, or different CMRs in the CMR information belong to different resource sets in the same resource setting.

[0052] Accordingly, when multiple IMRs are configured in a network side device, i.e., when the IMR information includes multiple IMRs, different IMRs in the IMR information belong to different resource settings, or different IMRs in the IMR information belong to the same resource set in the same resource setting, or different IMRs in the IMR information belong to different resource sets in the same resource setting.

[0053] In an embodiment of the present disclosure, the CMR in the CMR information may be a periodic-CMR (P-CMR), a semi-persistent-CMR (SP-CMR), or an aperiodic-CMR (AP-CMR), and the IMR in the IMR information may be a periodic-IMR (P-IMR), a semi-persistent-IMR (SP-IMR), or an aperiodic-CMR (AP-IMR). When configuring the P-CMR, SP-CMR, or AP-CMR and the P-IMR, SP-IMR, or AP-IMR information, the network side device may configure a transmission occasion association relationship between the CMR and the IMR.

[0054] Optionally, determining a target CMR and a target IMR for performing target L1-SINR measurement based on the predetermined correlation relationship includes: determining a second resource associated with the first resource based on the preset association relationship, wherein one of the first resource and the second resource is the target CMR and the other is the target IMR.

[0055] In this embodiment, the target CMR for performing channel measurement and the target IMR for performing interference measurement are CMRs and IMRs having an association relationship. For example, if CMR1 is associated with IMR1, when a terminal performs channel measurement on CMR1, the terminal performs interference measurement on IMR1, or when a terminal performs interference measurement on IMR1, the terminal performs channel measurement on CMR1.

[0056] Optionally, determining a target CMR and a target IMR for performing target L1-SINR measurement based on the predetermined correlation relationship includes: determining a third resource other than the second resource that is associated with the first resource based on the preset association relationship, wherein one of the first resource and the third resource is a target CMR and the other is a target IMR.

[0057] In this embodiment, the target CMR for performing channel measurement and the target IMR for performing interference measurement are unassociated CMRs and IMRs. For example, if CMR1 is associated with IMR1 but not associated with IMR2, when a terminal performs channel measurement for CMR1, the terminal performs interference measurement for IMR2, or when a terminal performs interference measurement for IMR2, the terminal performs channel measurement for CMR1.

[0058] In addition, in an embodiment of the present disclosure, when a terminal performs L1-SINR measurement, it may first determine a target CMR for performing channel measurement, and then determine a target IMR for performing interference measurement based on a pre-set association relationship, or it may first determine a target IMR for performing interference measurement, and then determine a target CMR for performing channel measurement based on a pre-set association relationship.

[0059] Optionally, performing an interferometric measurement on the target IMR comprises: and measuring the target IMR using quasi co-location (QCL) information of the target CMR.

[0060] In this embodiment, when a terminal measures the L1-SINR of a certain beam (i.e., the target L1-SINR), the used IMR (i.e., the target IMR) may use QCL information of the CMR (i.e., the target CMR) of this L1-SINR. In this way, the measurement direction when measuring the target CMR using the QCL information of this target CMR can be matched with the measurement direction when measuring the target IMR using the QCL information of this target CMR, thereby improving the accuracy of the measurement.

[0061] In an embodiment of the present disclosure, the IMR in the IMR information may include at least one of a zero power (ZP) IMR and a non-zero power (NZP) IMR, and for different types of IMR, the association relationship between the CMR and the ZP IMR and / or the NZP IMR can be flexibly pre-configured. For example, the network side device can flexibly configure the association relationship between the CMR and the ZP IMR and / or the NZP IMR.

[0062] The following describes the relationship between the CMR and the ZP IMR and / or the NZP IMR one by one. To better understand the manner in which the UE performs L1-SINR measurement in each relationship, the following description takes as an example that the UE first determines the CMR in which to perform channel measurement, and then determines the IMR manner in which to perform interference measurement based on the preset relationship.

[0063] Method 1: The IMR in the IMR information includes a ZP IMR; The predetermined association relationship is The association relationship between the CMR and the ZP IMR is an N-to-N association; The association relationship between the CMR and the ZP IMR is a one-to-one association; N CMRs are associated with one ZP IMR; One CMR is associated with N ZP IMRs.

[0064] This method provides four types of configuration methods for the association relationship between CMR and ZP IMR, specifically as follows:

[0065] First, the association relationship between a CMR and a ZP IMR is an N-to-N association, which may be understood as N CMRs being associated with N ZP IMRs, or as an N-to-one association (N is a positive integer greater than 1).

[0066] Such a pre-defined association relationship may be such that N CMRs in one CMR resource set have an association relationship with N ZP IMRs in one ZP IMR resource set. Specifically, the N CMRs in the CMR resource set with the smallest resource indexes are associated with the N ZP IMRs in the ZP IMR resource set with the smallest resource indexes, i.e., CMR1 in the CMR resource set is associated with ZP IMR1 in the ZP IMR resource set, and CMR2 in the CMR resource set is associated with ZP IMR2 in the ZP IMR resource set, and inferences are made based on this.

[0067] Alternatively, N CMRs determined by the index order of the CMR resource sets and the resource index order in each resource set in the CMR resource setting may be associated in order with N ZP IMRs determined by the index order of the ZP IMR resource sets and the resource index order in each resource set in the ZP IMR resource setting. For example, CMR1 of the first resource set in the CMR resource setting is associated with ZP IMR1 of the first resource set in the ZP IMR resource setting, CMR2 of the first resource set in the CMR resource setting is associated with ZP IMR2 of the first resource set in the ZP IMR resource setting, CMR1 of the second resource set in the CMR resource setting is associated with ZP IMR1 of the second resource set in the ZP IMR resource setting, and CMR2 of the second resource set in the CMR resource setting is associated with ZP IMR2 of the second resource set in the ZP IMR resource setting, and inferences can be made based on this.

[0068] Alternatively, N CMRs determined by the index order of the resource settings of the CMRs, the index order of the resource sets in each resource setting, and the resource index order in each resource set may be associated in order with N ZP IMRs determined by the index order of the resource settings of the ZP IMRs, the index order of the resource sets in the resource setting, and the resource index order in each resource set.For example, CMR1 of the first resource set in the first resource setting of the CMR is associated with ZP IMR1 of the first resource set in the first resource setting of the ZP IMR, CMR2 of the first resource set in the first resource setting of the CMR is associated with ZP IMR2 of the first resource set in the first resource setting of the ZP IMR, CMR1 of the second resource set in the first resource setting of the CMR is associated with ZP IMR1 of the second resource set in the first resource setting of the ZP IMR, CMR2 of the second resource set in the first resource setting of the CMR is associated with ZP IMR2 of the second resource set in the first resource setting of the ZP IMR, CMR1 of the first resource set in the second resource setting of the CMR is associated with ZP IMR1 of the first resource set in the second resource setting of the ZP IMR, and CMR2 of the first resource set in the second resource setting of the CMR is associated with ZP IMR. The first resource set in the second resource setting of IMR is associated with ZP IMR2, the second resource set CMR in the second resource setting of CMR is associated with ZP IMR1 of the second resource set in the second resource setting of ZP IMR, and the second resource set CMR2 in the second resource setting of CMR is associated with ZP IMR2 of the second resource set in the second resource setting of ZP IMR, and so on.

[0069] When a terminal measures beams, it may use the respective CMR when performing channel measurements for each beam, and may use the ZP IMR associated with each CMR when performing interference measurements for each beam. For example, CMR1 is used for channel measurements for beam1, and ZP IMR1 associated with CMR1 is used for interference measurements for beam1. Here, ZP IMR1 may be measured using QCL information for CMR1.

[0070] Furthermore, the CMR configured by the network side device is an aperiodic CMR, and the IMR configured by the network side device is an aperiodic IMR. Specifically, the network side device simultaneously triggers at least one reporting setting, and the reporting setting is associated with a resource setting of one aperiodic CMR and a resource setting of one aperiodic IMR, and in the resource set of each resource setting, the aperiodic CMR and the aperiodic IMR are N-to-N associated.

[0071] Second, the association relationship between the CMR and the ZP IMR is a one-to-one association.

[0072] The network side device may configure one report setting, associating one CMR resource setting with one ZP IMR resource setting, and the CMR and ZP IMR have a one-to-one association. Specifically, the associated CMR and ZP IMR may be determined based on at least one of the index order of the resource setting, the index order of the resource sets in each resource setting, and the resource index order in each resource set. For example, if the CMR resource setting has one resource set and the ZP IMR resource setting has one resource set, the first CMR of the resource set in the CMR resource setting is associated with the first ZP IMR of the resource set in the ZP IMR resource setting. Or, if the CMR resource setting has M resource sets, each resource set has one CMR, and the ZP IMR resource setting has M resource sets, each resource set has one ZP IMR, the CMR of the first resource set in the CMR resource setting is associated with the ZP IMR of the first resource set in the ZP IMR resource setting. Other one-to-one association schemes between CMR and ZP IMR also fall within the scope of protection of the present disclosure and will not be further described here.

[0073] Third, N CMRs are associated with one ZP IMR, where N is a positive integer greater than 1.

[0074] The network side device may configure one report setting, and associate N CMR resource settings with one ZP IMR resource setting, or associate one CMR resource setting including N resource sets with one ZP IMR resource setting including one resource set, where the CMR and ZP IMR are associated in an N-to-1 relationship, and the N CMRs may originate from the same resource setting or different resource settings, or from the same resource set or different resource sets.

[0075] For example, if there are N resource sets in the CMR resource setting and one resource set in the ZP IMR resource setting, the first CMR (N in total) of each resource set in the CMR resource setting is associated with the first ZP IMR of the resource set in the ZP IMR resource setting. Alternatively, if there are M resource sets in the CMR resource setting, each resource set has N CMRs, and the ZP IMR resource setting has M resource sets and each resource set has one ZP IMR, the N CMRs of the first resource set in the CMR resource setting are associated with the one ZP IMR of the first resource set in the ZP IMR resource setting. Alternatively, if there is one resource set in the CMR resource setting, N CMRs in the resource set in the CMR resource setting, and one resource set in the ZP IMR resource setting, the N CMRs of the resource set in the CMR resource setting are associated with the first ZP IMR of the resource set in the ZP IMR resource setting. Alternatively, if a CMR has N resource settings, each containing one resource set, and a ZP IMR has one resource setting, each containing one resource set, the first CMR in the resource set in each CMR resource setting (for a total of N) is associated with the first ZP IMR in the resource set in the ZP IMR resource setting.Other N-to-1 association schemes of CMR and ZP IMR also fall within the scope of protection of the present disclosure and will not be further described here.

[0076] When a terminal measures beams, it uses each CMR when performing channel measurements for each beam, and it uses the ZP IMR associated with each CMR when performing interference measurements for each beam, and the ZP IMR associated with each CMR is the same or the resources overlap.

[0077] Furthermore, the ZP IMR configured by the network side device may be a periodic ZP resource or a semi-persistent ZP resource, and the CMR configured by the network side device may be a periodic CMR, a semi-persistent CMR, or an aperiodic CMR.

[0078] Furthermore, when the network side device configures the information of the P-CMR, SP-CMR or AP-CMR and the P-IMR or SP-IMR, it also configures the associated relationship of the transmission occasion between the CMR and the IMR.

[0079] Fourth, one CMR is associated with N ZP IMRs, where N is a positive integer greater than 1.

[0080] The network side device may configure one report setting, and associate one CMR resource setting with N ZP IMR resource settings, or associate one CMR resource setting including one resource set with one ZP IMR resource setting including N resource sets, where the CMR and ZP IMR are associated in a 1:N relationship, and the N ZP IMRs may originate from the same resource setting or different resource settings (for example, the report setting associates resource settings of N ZP IMRs with the resource setting of one CMR), or may originate from the same resource set or different resource sets.

[0081] For example, if there is one resource set in the CMR resource setting and N resource sets in the ZP IMR resource setting, the first CMR in the resource set in the CMR resource setting is associated with the first ZP IMR (total of N) of each resource set in the ZP IMR resource setting. Alternatively, if there are M resource sets in the CMR resource setting, each resource set has one CMR, and the ZP IMR resource setting has M resource sets and each resource set has N ZP IMRs, the CMR in the first resource set in the CMR resource setting is associated with the N ZP IMRs of the first resource set in the ZP IMR resource setting. Alternatively, if there is one resource set in the CMR resource setting, one resource set in the ZP IMR resource setting, and the resource set in the ZP IMR resource setting has N ZP IMRs, the first CMR in the resource set in the CMR resource setting is associated with the N ZP IMRs of the resource set in the ZP IMR resource setting. Alternatively, if a CMR has one resource setting, each containing one resource set, and a ZP IMR has N resource settings, each containing one resource set, then the first CMR in the resource set in the CMR resource setting is associated with the first ZP IMR in the resource set in each ZP IMR resource setting (for a total of N).Other 1:N association schemes of CMR and ZP IMR also fall within the scope of protection of the present disclosure and will not be further described here.

[0082] Method 2: The IMR in the IMR information includes an NZP IMR; The predetermined association relationship is N CMRs are associated with one NZP IMR; N NZP IMRs are associated with one CMR; The association relationship between the CMR and the NZP IMR is a one-to-one association; The CMR includes one of the following: not associated with the NZP IMR.

[0083] Among them, the NZP IMR may be an NZP CSI Reference Signal (CSI-RS) or a Tracking Reference Signal (TRS).

[0084] One, N CMRs are associated with one NZP IMR, where N is an integer greater than 1.

[0085] The network side device may configure one report setting, and associate N CMR resource settings with one NZP IMR resource setting, or associate one CMR resource setting including N resource sets with one NZP IMR resource setting including one resource set, where the CMR and NZP IMR are associated in an N-to-1 relationship, and the N CMRs may originate from the same resource setting or different resource settings, or from the same resource set or different resource sets.

[0086] For example, if there are N resource sets in the CMR resource setting and one resource set in the NZP IMR resource setting, the first CMR (N in total) of each resource set in the CMR resource setting is associated with the first NZP IMR of the resource set in the NZP IMR resource setting. Alternatively, if there are M resource sets in the CMR resource setting, each resource set has N CMRs, and the NZP IMR resource setting has M resource sets, each resource set has one NZP IMR, the N CMRs of the first resource set in the CMR resource setting are associated with the one NZP IMR of the first resource set in the NZP IMR resource setting. Alternatively, if there is one resource set in the CMR resource setting, N CMRs in the resource set in the CMR resource setting, and one resource set in the NZP IMR resource setting, the N CMRs of the resource set in the CMR resource setting are associated with the first NZP IMR of the resource set in the NZP IMR resource setting. Alternatively, if a CMR has N resource settings, each containing one resource set, and an NZP IMR has one resource setting, each containing one resource set, then the first CMR in the resource set in each CMR resource setting (for a total of N) is associated with the first NZP IMR in the resource set in the NZP IMR resource setting.Other N-to-1 association schemes between CMR and NZP IMR also fall within the scope of protection of the present disclosure and will not be further described here.For aperiodic reports, the network side device may trigger one or more of the above-mentioned report settings.

[0087] When a terminal measures beams, it uses the respective CMRs when measuring channels for beam1, beam2, and beam3, i.e., CMR1, CMR2, and CMR3, respectively, and uses NZP IMR4 when measuring interference from beam4 on beam1, beam2, and beam3. CMR1, CMR2, and CMR3 are associated with NZP IMR4. When measuring interference for beam1, beam2, and beam3 using NZP IMR4, it measures NZP IMR4 using the QCL information of CMR1, CMR2, and CMR3, respectively.

[0088] Second, N NZP IMRs are associated with one CMR, where N is an integer greater than 1.

[0089] The network side device may configure one report setting, and associate one CMR resource setting with N NZP IMR resource settings, or associate one CMR resource setting including one resource set with one NZP IMR resource setting including N resource sets, where the CMR and NZP IMR are associated in a 1:N relationship, and the N NZP IMRs may originate from the same resource setting or different resource settings, or from the same resource set or different resource sets.

[0090] For example, if there is one resource set in the CMR resource setting and N resource sets in the NZP IMR resource setting, the first CMR of the resource set in the CMR resource setting is associated with the first NZP IMR of each resource set in the NZP IMR resource setting (for a total of N). Alternatively, if there are M resource sets in the CMR resource setting, each resource set has one CMR, and the NZP IMR resource setting has M resource sets, each resource set has N NZP IMRs, the CMR of the first resource set in the CMR resource setting is associated with the N NZP IMRs of the first resource set in the NZP IMR resource setting. Alternatively, if there is one resource set in the CMR resource setting, one resource set in the NZP IMR resource setting, and N NZP IMRs in the resource set in the NZP IMR resource setting, the first CMR in the resource set in the CMR resource setting is associated with the N NZP IMRs in the resource set in the NZP IMR resource setting. Alternatively, if there is one resource setting in the CMR, each resource setting contains one resource set, and there are N NZP IMRs in the N resource settings, each resource setting contains one resource set, the first CMR in the resource set in the CMR resource setting is associated with the first NZP IMR in the resource set in each NZP IMR resource setting (for a total of N).Other 1:N association schemes of CMR and NZP IMR also fall within the protection scope of the present disclosure and will not be further described here.

[0091] For aperiodic reporting, the network side device may trigger one or more of the report settings described above.

[0092] When a terminal measures beams, it uses CMR1 when performing channel measurements on beam1, and NZP IMR2, NZP IMR3, and NZP IMR4 when performing interference measurements on beam1, measuring the interference of beam2, beam3, and beam4 with beam1 respectively, i.e., CMR1 is associated with NZP IMR2, NZP IMR3, and NZP IMR4. When measuring NZP IMR2, NZP IMR3, and NZP IMR4, it uses the QCL information of CMR1.

[0093] Furthermore, it is not necessary to place an NZP IMR, but CMR1 is used when performing channel measurements for beam1, and CMR2, CMR3, and CMR4 are used when performing interference measurements for beam1, and the interference of beam2, beam3, and beam4 with beam1 is measured, respectively. When measuring CMR2, CMR3, and CMR4, the QCL information of CMR1 is used.

[0094] Third, the association relationship between the CMR and the NZP IMR is a one-to-one association, or the CMR is not associated with the NZP IMR.

[0095] The network side device may configure one report setting, associate one CMR resource setting with one NZP IMR resource setting, and the CMR and NZP IMR have a one-to-one association. Specifically, the network side device may determine the associated CMR and NZP IMR based on at least one of the index order of the resource setting, the index order of the resource set in each resource setting, and the resource index order in each resource set.

[0096] For example, if there is one resource set in the CMR resource setting and one resource set in the NZP IMR resource setting, the first CMR in the resource set in the CMR resource setting is associated with the first NZP IMR in the resource set in the NZP IMR resource setting. Or, if there are M resource sets in the CMR resource setting, each with one CMR, and there are M resource sets in the NZP IMR resource setting, each with one NZP IMR, the CMR in the first resource set in the CMR resource setting is associated with the NZP IMR in the first resource set in the NZP IMR resource setting. Other one-to-one association schemes between CMRs and NZP IMRs also fall within the scope of protection of the present disclosure and will not be described further here. In the above example, it may be permitted that there are NZP IMRs in the resource set in the NZP IMR resource setting that are not associated with any CMR, or that there are CMRs in the resource set in the CMR resource setting that are not associated with any NZP IMR.

[0097] When a terminal measures beams, for example, there are four beams in total, and the resource set in the CMR resource setting configurable by the network includes CMR1, CMR2, CMR3, and CMR4, which are respectively used for channel measurement of each beam. One NZP IMR resource setting may also be configured, of which NZP IMR1 and NZP IMR2 correspond to beam1 and beam2, respectively, NZP IMR1 is used to measure the interference of beam1 with beam2, beam3, and beam4, and NZP IMR2 measures the interference of beam2 with beam1, beam3, and beam4. Of which, CMR1 is associated with NZP IMR1, CMR2 is associated with NZP IMR2, and CMR3 and CMR4 are not associated with NZP IMR.

[0098] When measuring the L1-SINR of beam1, for interference measurement from beam2, the interference measured by the IMR with the resource ID of the IMR corresponding to the resource ID of the CMR corresponding to beam1 is removed during interference measurement. That is, interference measurement is performed on an NZP IMR other than NZP IMR1 associated with CMR1 (i.e., NZP IMR2), and the interference measurement result of beam2 with beam1 is obtained. When measuring NZP IMR2, the QCL information of CMR1 is used. When measuring interference from beam3 and beam4, interference measurement can be performed using CMR3 and CMR4, and the QCL information of CMR1 can be used when measuring NZP IMR3 and NZP IMR4. Alternatively, there is no need to measure interference from beam3 and beam4.

[0099] When measuring the L1-SINR of beam3, CMR3 is used to measure the channel, and NZP IMR1, NZP IMR2, and CMR4 are used to measure the interference from beam1, beam2, and beam4, respectively. When measuring NZP IMR1, NZP IMR2, and CMR4, the QCL information of CMR3 is used. There is no need to measure the interference from beam4.

[0100] Method 3: The IMR in the IMR information includes ZP IMR and NZP IMR.

[0101] The predetermined association relationship is The associative relationship between the CMR, the ZP IMR, and the NZP IMR is 1 to M to N, including M and N being positive integers.

[0102] The network side device may configure one report setting and associate one CMR resource setting, at least one ZP IMR resource setting, and at least one NZP IMR resource setting, and the three resources are associated in a 1:M:N relationship. The network side device may simultaneously trigger multiple such report settings.

[0103] Wherein, the correlation relationship between the CMR, the ZP IMR and the NZP IMR may be 1 to M to N, that is, M may be equal to 1.

[0104] For example, when M is equal to 1, if there is one resource set in the CMR resource setting, one resource set in the ZP IMR resource setting, and N resource sets in the NZP IMR resource setting, the first CMR in the resource set in the CMR resource setting and the first ZP IMR in the resource set in the ZP IMR resource setting are associated with the first NZP IMR in each resource set in the NZP IMR resource setting (a total of N), and the inference is based on this. Alternatively, if there is one resource setting in the CMR, one resource setting in the ZP IMR, and N resource settings in the NZP IMR, and each resource setting has one resource set, the first CMR in the resource set in the CMR resource setting and the first ZP IMR in the resource set in the ZP IMR resource setting are associated with the first NZP IMR in each resource set in the NZP IMR resource setting (a total of N), and the inference is based on this.

[0105] Other one-to-one-to-N association schemes of CMR, ZP IMR and NZP IMP also fall within the protection scope of the present disclosure and will not be further described here.

[0106] Also, for example, if there is one resource set in the CMR resource setting, M resource sets in the ZP IMR resource setting, and N resource sets in the NZP IMR resource setting, the first CMR of the resource set in the CMR resource setting and the first ZP IMR of each resource set in the ZP IMR resource setting (M in total) are associated with the first NZP IMR of each resource set in the NZP IMR resource setting, and inference is made based on this. Alternatively, if there is one resource setting in the CMR, M resource settings in the ZP IMR, and N resource settings in the NZP IMR, and each of the above resource settings has one resource set, the first CMR of the resource set in the CMR resource setting and the first ZP IMR of each resource set in each ZP IMR resource setting (M in total) are associated with the first NZP IMR of the resource set in each NZP IMR resource setting, and inference is made based on this.

[0107] Other 1 to M to N association schemes of CMR, ZP IMR and NZP IMP also fall within the protection scope of the present disclosure and will not be further described here.

[0108] When measuring the L1-SINR of beam1, the terminal uses the interference of the cumulative measurements of ZP IMR and NZP IMR when performing interference measurements. However, if an IMR associated with a CMR corresponding to beam1 is used to perform interference measurements on another beam, the terminal may remove the interference measured by the IMR of the resource id of the IMR corresponding to the resource id of the CMR corresponding to beam1 when performing interference measurements on beam1, i.e., perform interference measurements using an IMR other than the IMR associated with the CMR corresponding to beam1, and use the QCL information of the CMR corresponding to beam1 when measuring an IMR other than the IMR associated with the CMR corresponding to beam1.

[0109] Among them, ZP IMR may be used for inter-cell interference measurement, and NZP IMR may be used for inter-beam interference measurement.

[0110] In addition to the above-mentioned 1-to-M-to-N association relationship, the CMR, ZP IMR, and NZP IMR may have various other possible relationships. The network side device may configure one report setting, and associate at least one CMR resource setting, at least one ZP IMR resource setting, and at least one NZP IMR resource setting, and there may be other association relationships between the CMR, ZP IMR, and NZP IMR in the above three types of resource settings.

[0111] To summarize the above embodiments, the correlation between CMR and IMR for L1-SINR measurement is flexibly configured or stipulated by a protocol, so that when a terminal performs L1-SINR measurement, it can select the correct CMR and IMR to perform channel measurement and interference measurement based on the correlation between CMR and IMR, thereby improving the accuracy of L1-SINR measurement and the communication reliability of the communication system.
