[0020] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The embodiments of the present disclosure may be used in a wireless communication system. The wireless communication system may be a 5G system, or 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 system includes a terminal 11 and a network side device 12, in which the terminal 11 may be a mobile communication device, for example, a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (Mobile Internet Device, MID), or a wearable device. Note that, in the embodiment of the present disclosure, the specific type of the terminal 11 is not limited. The network side device 12 may be a 5G network side device (e.g., gNB, 5G NR NB), or a 4G network side device (e.g., eNB), or a 3G network side device (e.g., NB), or a network side device in a later evolution communication system, etc. Note that, in the embodiment of the present disclosure, the specific type of the network side device 12 is not limited.
[0022] Before describing the technical solutions of the embodiments of the present disclosure in detail, a brief introduction to Massive MIMO technology will first be given.
[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 rates and system spectrum utilization.
[0024] With the expansion of the dimension of MIMO technology, Rel-8 can support up to four layers of MIMO transmission, Rel-9 can support up to four downlink data layers in extended MU-MIMO technology and MU-MIMO transmission in Transmission Mode (TM)-8, and Rel-10 can extend the transmission capacity of Single-User MIMO (SU-MIMO) to up to eight data layers.
[0025] Research into next-generation communication systems beyond 4G has increased the operating frequency band supported by the system to 6 GHz or higher, 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 signals have shorter wavelengths, and compared to low-frequency bands, more antenna array elements can be arranged on a panel of the same size and beamforming technology can be used to form beams with stronger directionality and narrower wavebands. Therefore, it can be predicted that MIMO technology with larger scale and more antenna ports (i.e., Massive MIMO technology) will be introduced in future 5G mobile communication systems. The use of large-scale antenna arrays can significantly improve the utilization efficiency of the system frequency band and support more access users.
[0026] In Massive MIMO technology, the adoption of 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 imposes a heavy burden on both equipment costs and baseband processing complexity.
[0027] In order to reduce the implementation cost and processing complexity, digital-analog hybrid beamforming technology has been developed, that is, on top of the traditional digital domain beamforming, beamforming is added by one step to the radio frequency signal near the front end of the antenna system. Simulation beamforming can achieve a relatively rough matching of the transmission signal and the channel in a relatively simple manner. The dimension of the equivalent channel formed after simulation beamforming is smaller than the number of actual antennas, so that the complexity of the AD / DA conversion device, the number of digital channels, and the corresponding baseband processing required afterwards can be greatly reduced. In simulation beamforming, the partially remaining interference can be reprocessed in the digital domain to ensure the quality of MU-MIMO transmission. Compared to full digital beamforming, digital-analog hybrid beamforming is a trade-off scheme between performance and complexity, and has a relatively high practical prospect in systems with high frequency bands, large bandwidths, or a large number of antennas.
[0028] The simulated beamforming is launched in the full bandwidth, and each polarization direction array element on each radio frequency antenna array panel can only transmit a simulated beam in the manner of time division multiplexing. The forming weight value of the simulated beam is realized by adjusting the parameters of the equipment such as the phase shifter of the radio frequency front end. At present, the simulation beamforming vector is generally trained in the manner of polling, that is, each polarization direction array element of each antenna panel transmits a training signal (i.e., a candidate forming vector) in turn at a predetermined time in the manner of time division multiplexing, and the terminal feeds back a beam report after measurement, and the network side adopts this training signal when transmitting the service next time to realize the simulated beam launch.
[0029] In beam measurement and selection, the parameter commonly used to measure beam quality is Layer 1-reference signal received power (L1-RSRP). In order 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 yet for how to configure the CMR and IMR, for example, how to configure the associated relationship between the CMR and IMR, which will affect 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 Fig. 1, and a resource allocation and measurement method for L1-SINR measurement used in the network system. As shown in Fig. 2, the method includes the following steps:
[0031] Step 201: A network side device transmits configuration information to a terminal.
[0032] Wherein, the configuration information is used to instruct to measure 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 association relationship 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] In addition, the order of execution of the above steps 203 and 204 is not limited, and step 203 may be executed first and then step 204, or step 204 may be executed first and then steps 202 and 203, or step 203 and step 204 may be executed simultaneously.
[0038] In an embodiment of the present disclosure, by presetting a correlation between the CMR and IMR for L1-SINR measurement, when a terminal performs L1-SINR measurement, the terminal can select the correct CMR and IMR to perform channel measurement and interference measurement based on the correlation between the CMR and IMR, thereby improving the communication reliability of the communication system.
[0039] 3 is a flow chart 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 to measure 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, the CSI report setting may include measurement report parameters, and the measurement report parameters may further include L1-RSRP in addition to L1-SINR. That is, the configuration information may be used to instruct to measure L1-SINR, or may be used to instruct to measure L1-SINR and L1-RSRP.
[0042] The configuration information may be Radio Resource Control (RRC) signaling. The configuration information includes CMR information, which may be understood as the configuration information can configure at least one RS resource setting (reference signal resource setting) for channel measurement (CM). The configuration information includes IMR information, which may be understood as the configuration information can configure 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 embodiment of the present disclosure, when the network side device configures to measure the L1-SINR of a beam, multiple CMR resource settings and IMR resource settings can be flexibly configured.
[0043] In the embodiment 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 a non-association. The preset association relationship may be preset relatively flexibly, thereby improving the flexibility of the L1-SINR measurement.
[0044] The predefined association relationship may be configured by a network side device, for example, may be configured in the configuration information, or may be agreed upon by a protocol.
[0045] Step 302: Determine a target CMR and a target IMR for performing target L1-SINR measurement according to the preset association relationship.
[0046] In this step, after receiving the configuration information sent by the network side device, the terminal may select a correct target CMR and a target IMR to perform target L1-SINR measurement according to a preset association relationship between the CMRs and the 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 can measure the target CMR to obtain a target channel measurement result, and the terminal can measure the target IMR to obtain a target interference measurement result, and then calculate the target L1-SINR by using the target channel measurement result as the numerator and the target interference measurement result as the denominator.
[0049] In an embodiment of the present disclosure, by presetting a correlation between the CMR and IMR for L1-SINR measurement, when a terminal performs L1-SINR measurement, the terminal can select the correct CMR and IMR to perform channel measurement and interference measurement based on the correlation between the 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 the network side device configures the information of the P-CMR, SP-CMR, or AP-CMR and the P-IMR, SP-IMR, or AP-IMR, it can configure the associated relationship of the transmission occasion between the CMR and the IMR.
[0054] Optionally, determining a target CMR and a target IMR for performing a target L1-SINR measurement based on the predetermined association relationship includes: determining a second resource associated with the first resource based on the preset association relationship, one of the first resource and the second resource being the target CMR and the other being the target IMR.
[0055] In this embodiment, the target CMR performing channel measurement and the target IMR performing interference measurement are CMRs and IMRs having an association relationship. For example, when CMR1 is associated with IMR1, if the terminal performs channel measurement on CMR1, the terminal performs interference measurement on IMR1, or if the 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 a target L1-SINR measurement based on the predetermined association relationship includes: determining a third resource other than the second resource that is associated with the first resource based on the preset association relationship, one of the first resource and the third resource being a target CMR and the other being a target IMR.
[0057] In this embodiment, the target CMR for performing channel measurement and the target IMR for performing interference measurement are unassociated CMR and IMR. For example, when CMR1 is associated with IMR1 but CMR1 is not associated with IMR2, if the terminal performs channel measurement for CMR1, the terminal performs interference measurement for IMR2, or if the 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 an 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 includes: 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 (i.e., target L1-SINR) of a certain beam, the used IMR (i.e., target IMR) may use the QCL information of the CMR (i.e., 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 the 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. In order to better understand the manner in which the terminal performs L1-SINR measurement in each relationship, the following description takes as an example that the terminal first determines the CMR in which the terminal performs channel measurement, and then determines the IMR manner in which the terminal performs interference measurement according to the preset relationship.
[0063] Method 1: The IMR in the IMR information includes a ZP IMR; The preset 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] In this method, four configuration methods of the association relationship between the CMR and the ZP IMR are provided, which are 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 it may be understood as an N-to-one association (N is a positive integer greater than 1).
[0066] In such a pre-set association relationship, N CMRs in one CMR resource set may 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 set in the CMR 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 ZP IMR resource set in the ZP IMR resource setting and the resource index order in each resource set. 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 are made based on this.
[0068] Alternatively, the N CMRs determined by the index order of the resource settings of the CMR, 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 the N ZP IMRs determined by the index order of the resource settings of the ZP IMR, 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. ZP IMR2 of the first resource set in the second resource setting of IMR is associated with ZP IMR1 of the second resource set in the second resource setting of CMR, and CMR2 of the second resource set 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 inferences are made based on this.
[0069] When the terminal measures beams, it may use each CMR when performing channel measurement for each beam, and may use the ZP IMR associated with each CMR when performing interference measurement for each beam. For example, CMR1 is used for channel measurement of beam1, and ZP IMR1 associated with CMR1 is used for interference measurement of beam1. Here, ZP IMR1 may be measured using QCL information of 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, and associate one CMR resource setting with one ZP IMR resource setting, and the CMR and the ZP IMR are one-to-one associated. 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 set in each resource setting, and the resource index order in each resource set. For example, when there is one resource set in the CMR resource setting and there is one resource set in the ZP IMR resource setting, 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, when there are M resource sets in the CMR resource setting, each resource set has one CMR, and there are M resource sets in the ZP IMR resource setting, 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 this disclosure and will not be described further 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 ratio, and the N CMRs may originate from the same resource setting or different resource settings, or may originate 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. Or, if there are M resource sets in the CMR resource setting and each resource set has N CMRs, and there are M resource sets in the ZP IMR resource setting and each resource set has one ZP IMR, the N CMRs of the first resource set in the CMR resource setting are associated with one ZP IMR of the first resource set in the ZP IMR resource setting. Or, if there is one resource set in the CMR resource setting and there are N CMRs in the resource set in the CMR resource setting and there is 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. Or, if a CMR has N resource settings, each of which contains one resource set, and a ZP IMR has one resource setting, each of which contains 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 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 this disclosure and will not be described further here.
[0076] When a terminal performs beam measurements, 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 may 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 on a 1-to-N basis, and the N ZP IMRs may originate from the same resource setting or different resource settings (for example, a report setting associates resource settings of N ZP IMRs with a 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 of the resource set in the CMR resource setting is associated with the first ZP IMR of each resource set in the ZP IMR resource setting (N in total). Or, if there are M resource sets in the CMR resource setting, each resource set has one CMR, the ZP IMR resource setting has M resource sets, and each resource set has N ZP IMRs, the CMR of the first resource set in the CMR resource setting is associated with the N ZP IMR of the first resource set in the ZP IMR resource setting. Or, 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 of the resource set in the CMR resource setting is associated with the N ZP IMR of the resource set in the ZP IMR resource setting. Or, 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 this disclosure and will not be described further here.
[0082] Method 2: The IMR in the IMR information includes an NZP IMR; The preset 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 related to 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] First, 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 ratio, 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. Or, if there are M resource sets in the CMR resource setting and each resource set has N CMRs, and there are M resource sets in the NZP IMR resource setting and each resource set has one NZP IMR, the N CMRs of the first resource set in the CMR resource setting are associated with one NZP IMR of the first resource set in the NZP IMR resource setting. Or, if there is one resource set in the CMR resource setting and there are N CMRs in the resource set in the CMR resource setting and there is 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. Or, if a CMR has N resource settings, each of which contains one resource set, and an NZP IMR has one resource setting, each of which contains 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 methods of CMR and NZP IMR also belong to the scope of protection of the present disclosure and will not be described further 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 performing channel measurements for beam1, beam2, and beam3, i.e., CMR1, CMR2, and CMR3, respectively, and uses NZP IMR4 when measuring interference of beam4 with beam1, beam2, and beam3. CMR1, CMR2, and CMR3 are associated with NZP IMR4. When measuring interference with 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 may 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 on a 1-to-N basis, and the N NZP IMRs may originate from the same resource setting or different resource settings, or may originate 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). Or, if there are M resource sets in the CMR resource setting and each resource set has one CMR, and there are M resource sets in the NZP IMR resource setting and 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 IMR of the first resource set in the NZP IMR resource setting. Or, if there is one resource set in the CMR resource setting, one resource set in the NZP IMR resource setting, and there are 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, or, if there is one resource setting in the CMR, and each resource setting contains one resource set, or if there are N resource settings in the NZP IMR, and 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 methods of CMR and NZP IMR also fall within the scope of protection of this disclosure and will not be described further here.
[0091] For aperiodic reporting, the network side device may trigger one or more of the report settings described above.
[0092] When the terminal measures beams, it uses CMR1 when performing channel measurement for beam1, and uses NZP IMR2, NZP IMR3, and NZP IMR4 when performing interference measurement for beam1, respectively measuring the interference of beam2, beam3, and beam4 with beam1, i.e., CMR1 is associated with NZP IMR2, NZP IMR3, and NZP IMR4. When measuring NZP IMR2, NZP IMR3, and NZP IMR4, the QCL information of CMR1 is used.
[0093] Furthermore, it is not necessary to place an NZP IMR, but CMR1 is used when performing channel measurement for beam1, and CMR2, CMR3, and CMR4 are used when performing interference measurement 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 the NZP IMR are one-to-one associated. 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 of the resource set in the CMR resource setting is associated with the first NZP IMR of the resource set in the NZP IMR resource setting. Or, if there are M resource sets in the CMR resource setting, each resource set has one CMR, and there are M resource sets in the NZP IMR resource setting, each resource set has one NZP IMR, the CMR of the first resource set in the CMR resource setting is associated with the NZP IMR of the first resource set in the NZP IMR resource setting. Other one-to-one association methods between CMRs and NZP IMRs also belong to the scope of protection of the present disclosure and will not be described further here. In the above example, it may be allowed that there is an NZP IMR that is not associated with each CMR in the resource set of the NZP IMR resource setting, or that there is a CMR that is not associated with each NZP IMR in the resource set of the CMR resource setting.
[0097] When the terminal measures beams, for example, there are four beams in total, and the resource set in the CMR resource setting that can be configured by the network includes CMR1, CMR2, CMR3, and CMR4, which are used for channel measurement of each beam. One NZP IMR resource setting may be further configured, among which NZP IMR1 and NZP IMR2 correspond to beam1 and beam2, respectively, NZP IMR1 is used to measure the interference of beam1 to beam2, beam3, and beam4, and NZP IMR2 measures the interference of beam2 to beam1, beam3, and beam4. Among them, 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 L1-SINR of beam1, for interference measurement from beam2, the interference measured by the IMR of 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 another NZP IMR (i.e., NZP IMR2) other than NZP IMR1 associated with CMR1, and the interference measurement result of beam2 against beam1 is obtained, and the QCL information of CMR1 is used when measuring NZP IMR2. When measuring interference from beam3 and beam4, interference measurement may be performed using CMR3 and CMR4, and the QCL information of CMR1 may be used when measuring NZP IMR3 and NZP IMR4. Or, there is no need to measure interference from beam3 and beam4.
[0099] When measuring L1-SINR of beam3, use CMR3 to measure the channel, and use NZP IMR1, NZP IMR2, and CMR4 to measure the interference from beam1, beam2, and beam4, respectively, and use the QCL information of CMR3 when measuring NZP IMR1, NZP IMR2, and CMR4. 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 preset 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-to-M-to-N relationship. The network side device may simultaneously trigger multiple such report settings.
[0103] Wherein, the association relationship between the CMR, the ZP IMR and the NZP IMR may be 1 to M to N, that is, M is 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 of the resource set in the CMR resource setting and the first ZP IMR of the resource set in the ZP IMR resource setting are associated with the first NZP IMR of each resource set in the NZP IMR resource setting (total of N), and inference is based on this. Or, 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 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 the resource set in the ZP IMR resource setting are associated with the first NZP IMR of the resource set in each NZP IMR resource setting (total of N), and inference is based on this.
[0105] Other 1:1:N association schemes of CMR, ZP IMR and NZP IMP also fall within the scope of protection of the present disclosure and will not be described further 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. Or, 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 (N in total) 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 scope of protection of this disclosure and will not be described further here.
[0108] When the terminal measures the L1-SINR of beam1, it uses the cumulative measured interference of ZP IMR and NZP IMR when performing interference measurement, but if an IMR associated with a CMR corresponding to beam1 is used to perform interference measurement for another beam, it 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 measurement for beam1, i.e., perform interference measurement 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 1-to-M-to-N 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 relationship 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 the CMR and IMR for L1-SINR measurement is flexibly arranged or agreed upon 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 the CMR and IMR, thereby improving the accuracy of L1-SINR measurement and improving the communication reliability of the communication system.
