Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, communication device, and electronic device. Background Technology

[0002] In wireless communication systems between user equipment (UE) and network equipment, to support dynamic scheduling and downlink multiple-input multiple-output (MIMO) transmission technology, the UE needs to measure and report channel state information (CSI) to the network equipment. CSI enables the wireless communication system to adapt to current channel conditions, ensuring high communication quality for multi-antenna systems supporting MIM0 technology.

[0003] With the increasing popularity of MIM0 technology, coordinated multipoint transmission (CoMP) has become well-known due to its ability to effectively solve inter-cell interference problems and improve edge user throughput. As one of the mainstream CoMP solutions, coherent joint transmission (CJT) is also being widely adopted. However, for wireless communication systems based on CJT, existing technologies have not yet proposed specific configuration information for Channel State Information (CSI) measurement. Therefore, a specific configuration and measurement mechanism for CSI measurement in coherent CJT is urgently needed. Summary of the Invention

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0048] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0049] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a wireless communication system provided in an embodiment of this application. Figure 1 As shown, the wireless communication system mainly includes network equipment 10 and user equipment 20. Furthermore, the network equipment 10 and user equipment 20 employ a multi-site coherent joint transmission scheme to achieve uplink and downlink transmission of data or signaling. Specifically, the network equipment 10 can consist of multiple sites, such as... Figure 1 The diagram shows stations 1, 2, and N. Here, N is a positive integer greater than or equal to N. These N stations will work together to provide services to user equipment 20. It should be understood that, for user equipment 20, these N stations are equivalent to a single network device 10, and user equipment 20 is also sending and receiving data or signaling data via network device 10. For ease of understanding and description, the above N stations will be consistently referred to as network device 10 in the following text.

[0050] It should be noted that the multi-site coherent joint transmission involved in this application can refer to joint coherent transmission of multiple sites, or it can refer to different data belonging to the same physical downlink shared channel (PDSCH) being sent from different sites to the terminal device, or it can refer to multiple sites being virtually merged into one site for transmission. It should be understood that names with the same meaning as those specified in other standards also apply to this application; that is, this application does not limit the names of these scenarios.

[0051] In practical implementation, the sites involved in this application (such as sites 1 to N mentioned above) can be remote radio heads (RRHs) and / or transmission reception points (TRPs). In other words, the coherent joint transmission scheme involved in this application can be implemented based on multiple remote radio heads (RRHs) or multiple transmission and reception points (TRPs). Here, the aforementioned transmission and reception points (TRPs) can specifically be base stations (BSs). A base station is a device deployed in a radio access network to provide wireless communication functions. For example, in 2G networks, equipment providing base station functionality includes base transceiver stations (BTS) and base station controllers (BSCs); in 3G networks, it includes NodeBs (NodeBs) and radio network controllers (RNCs); in 4G networks, it includes evolved NodeBs (eNBs); in wireless local area networks (WLANs), it is the access point (AP); in 5G New Radio (NR), it includes further evolved NodeBs (gNBs); and it includes equipment providing base station functionality in future communication systems. This application does not limit the specific implementation form of the site.

[0052] The user equipment involved in this application can be any type of device that provides voice and / or data connectivity to a user, such as a handheld device with wireless connectivity or a processing device connected to a wireless modem. For example, it can include mobile phones (or "cellular" phones), computers with mobile terminals, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices, smart wearable devices, etc. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), smart bracelets, smartwatches, and other devices. It also includes limited devices, such as devices with low power consumption, limited storage capacity, or limited computing power. Other examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners. Furthermore, chips used in the above devices can also be called user equipment. This application does not impose specific limitations on the specific implementation form of the user equipment.

[0053] In addition, the aforementioned wireless communication system may specifically be a 5G (5-generation) communication system that supports coherent joint transmission schemes, or a 2G, 3G, or 4G communication system that supports coherent joint transmission schemes, or a satellite communication system that supports coherent joint transmission schemes, or various communication systems that support subsequent evolutions of coherent joint transmission schemes, such as 6G and 7G. This application does not impose any specific limitations on these.

[0054] Due to Figure 1 The existing technology for wireless communication systems does not provide specific configuration information for Channel State Information (CSI) measurement. Therefore, the technical problem this application aims to solve is to provide a processing method for CSI measurement in coherent joint transmission schemes, thereby improving the applicability and practicality of coherent joint transmission schemes in wireless communication systems.

[0055] Please see Figure 2 , Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application. For example... Figure 2 As shown, the method includes the following steps:

[0056] S21, the network device generates the first message containing CSI report configuration information.

[0057] In some optional implementations, when network device 10 determines that user equipment 20 needs to perform CSI measurements, network device 10 can generate a first message containing at least CSI report configuration information. This first message can be used by user equipment 20 to perform CSI measurements and report them. The aforementioned CSI report configuration information contains at least one target codebook type, and this target codebook type is a codebook type of a coherent joint transmission scheme. In other words, the target codebook type can be a codebook type under the assumption of a coherent joint transmission scheme. It should be noted that the target codebook type being a codebook type of a coherent joint transmission scheme can be understood as meaning that the target codebook type is applicable to a joint coherent transmission scheme.

[0058] In specific implementation, when it is planned or determined that a coherent joint transmission scheme will be used for wireless communication with user equipment 20, network device 10 can generate CSI report configuration information suitable for user equipment 20 based on network status information between it and user equipment 20 and preset CSI configuration rules. This CSI report configuration information is mainly used to inform user equipment 20 how to subsequently report the CSI report it obtained based on the aforementioned first message. In particular, since a coherent joint transmission scheme is used, the aforementioned CSI report configuration information should include at least one target codebook type of the coherent joint transmission scheme, so that the CSI report subsequently reported by user equipment 20 includes this target codebook type.

[0059] For example, the target codebook type mentioned above can specifically be a codebook type such as typeII-r18, typeII-PortSelection-r18, typeI-MultiPanel-r18, or typeI-r18, which are applicable to coherent joint transmission schemes. It should be understood that the above description is only an exemplary description of the target codebook type. In actual use, the target codebook type can also be any other codebook type applicable to coherent joint transmission schemes, and this application does not impose any specific restrictions on it.

[0060] In one optional implementation, the CSI report configuration information may include codebook configuration information, and the target codebook type may be included in the codebook configuration information.

[0061] In an alternative implementation, the aforementioned target codebook type can also serve as an indicator to inform user equipment 20 that it should perform CSI measurements based on the coherent joint transmission scheme assumption to obtain a CSI report. In other words, when user equipment 20 extracts the aforementioned target codebook type from the CSI report configuration information, it can determine that it should perform CSI measurements based on the coherent joint transmission scheme assumption to obtain a CSI report.

[0062] Therefore, it can be understood that the CSI report subsequently reported by the user equipment contains a codebook, and the codebook type of this codebook is the target codebook type. It should be noted that the so-called CSI report containing a codebook can be understood as the CSI report reported by user 20 containing a PMI, or as the CSI report containing the codebook indicated by the PMI, or as the CSI report containing a PMI belonging to the codebook, or as the CSI report containing a codebook indication, or as the CSI report containing a precoding matrix indicated by the PMI, or as the CSI report containing a precoding matrix indicated by a PMI belonging to the codebook, or as the CSI report containing a PMI indicating the codebook, or as the CSI report containing a PMI indicating a precoding matrix belonging to the codebook.

[0063] In one optional implementation, the first message may further include CSI measurement resource information, which includes N1 channel measurement resources. Here, N1 is a positive integer greater than or equal to 1. These N1 channel measurement resources can be used by the user equipment 20 for subsequent CSI measurement and calculation. Optionally, each of the N1 channel measurement resources may specifically be time-domain resources, frequency-domain resources, or other information corresponding to the SSB or CSI reference signal (i.e., CSI-RS).

[0064] Furthermore, the aforementioned CSI measurement resource information may contain N2 channel measurement resource sets. Each of these N2 channel measurement resource sets contains one or more channel measurement resources, and the total number of channel measurement resources contained in these N2 channel measurement resource sets is N1. N2 is a positive integer greater than or equal to 1. In other words, the aforementioned N1 channel measurement resources exist in the aforementioned CSI measurement resource information in the form of N2 channel measurement resource sets, and one or more of these N1 channel measurement resources constitute a single channel measurement resource set.

[0065] Furthermore, the total number of ports of one or more channel measurement resources contained in any of the aforementioned N2 channel measurement resource sets should be less than or equal to 32. For example, assuming that channel measurement resource set A in the aforementioned N2 channel measurement resource sets contains 5 channel measurement resources, then the total number of ports corresponding to these 5 channel measurement resources should not exceed 32.

[0066] Alternatively, the total number of ports of one or more channel measurement resources contained in a portion of the aforementioned N2 channel measurement resource sets should be less than or equal to 32, while the total number of ports of each channel measurement resource in another portion of the aforementioned N2 channel measurement resource sets may not be specifically limited.

[0067] In an optional implementation, the first message may further include a preset threshold (hereinafter referred to as the first threshold for clarity). This first threshold can be used to determine the indication information of channel measurement resources included in the CSI report reported by the user equipment. For example, assuming that the CSI report reported by the user equipment contains indication information of N3 channel measurement resources, then the difference or absolute value of the channel measurement results corresponding to any two of these N3 channel measurement resources must be less than or equal to the first threshold. Here, the N3 channel measurement resources refer to some or all of the N1 channel measurement resources mentioned above, that is, N3 is less than or equal to N1.

[0068] It should be noted that the channel measurement resource indication information involved in this application is information that can uniquely indicate the channel measurement resource. This indication information can be information in any form of implementation, such as binary numbers or symbols with different values. This application does not impose specific restrictions on the implementation form of the channel measurement resource indication information.

[0069] Optionally, the measurement results corresponding to the aforementioned channel measurement resources may specifically be parameters such as reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-noise ratio (SNR) measured by the user equipment 20 on this channel measurement resource. This application does not impose specific limitations on these parameters.

[0070] In an alternative implementation, the CSI measurement resource information may not include the interference measurement resource associated with the CSI report configuration information. Here, the interference measurement resource may specifically be the CSI interference measurement resource (i.e., (CSI-interference measurement, CSI-IM)).

[0071] It should be understood that the above CSI measurement resource information may not include the interference measurement resources associated with the above CSI report configuration information. In other words, the above CSI measurement resource information may not include interference measurement resources.

[0072] In one alternative implementation, the aforementioned CSI measurement resource information may include one or more interference measurement resources associated with the aforementioned CSI report configuration information.

[0073] It should be understood that the above CSI measurement resource information may include one or more interference measurement resources associated with the above CSI report configuration information.

[0074] Similarly, the one or more interference measurement resources mentioned above (here assumed to be N6) can also exist in the above CSI measurement resource information in the form of interference measurement resource sets. Here, N6 is a positive integer greater than or equal to 1. That is to say, in a specific implementation, the above CSI measurement resource information may include one or more interference measurement resource sets, and each interference measurement resource set may contain one or more interference measurement resources, and the total number of interference measurement resources contained in this one or more interference measurement resource sets is N6.

[0075] In one optional implementation, the aforementioned N1 channel measurement resources include N4 first channel measurement resources, which can serve as interference measurement resources. Here, these N4 first channel measurement resources are the channel measurement resources other than the N5 second channel measurement resources among the aforementioned N1 channel measurement resources. The indication information of the aforementioned N5 second channel measurement resources is included in the CSI report reported by the user equipment 20.

[0076] For example, suppose the aforementioned N1 channel measurement resources include channel measurement resource R1, channel measurement resource R2, channel measurement resource R3, and channel measurement resource R4, with corresponding indication information r1, r2, r3, and r4, respectively. If user equipment 20 subsequently determines that channel measurement resources R2, R3, and R4 are channel measurement resources that need to be reported, that is, if its subsequent CSI report contains the aforementioned indication information r2, r3, and r4, then channel measurement resources R2, R3, and R4 become the second channel measurement resource, and channel measurement resource R1 becomes the first channel measurement resource. Therefore, in the subsequent CSI measurement process, user equipment 20 can use channel measurement resource R1 as an interference measurement resource for interference measurement.

[0077] It should be noted that when the first message includes the aforementioned first threshold, the N5 second channel measurement resources are equivalent to the N3 channel measurement resources mentioned above. However, when the first message does not include the aforementioned first threshold, the N5 second channel measurement resources can be the channel measurement resources that the user equipment 20 determines from the aforementioned N1 channel resources and needs to be reported using other preset rules. This application does not specifically limit the method by which the user equipment 20 determines the aforementioned N5 second channel measurement resources.

[0078] In some optional implementations, if the aforementioned N1 channel measurement resources include the aforementioned N4 first channel measurement resources, and if the aforementioned CSI measurement resource information also includes one or more interference measurement resources associated with the CSI report configuration information, then these one or more interference measurement resources may not be used for the CSI measurements performed by the user equipment 20. In other words, when both the N4 first channel measurement resources and one or more interference measurement resources associated with the CSI report configuration information exist simultaneously, the user equipment 20 can use only these N4 first channel measurement resources as interference measurement resources to perform interference measurements in order to obtain the interference measurement results required to generate the CSI report.

[0079] In some optional implementations, if the CSI measurement resource information mentioned above also includes one or more interference measurement resources associated with the CSI report configuration information, then these one or more interference measurement resources can also be used for CSI measurements performed by the user equipment 20.

[0080] S22, the network device sends a first message to the user equipment. Correspondingly, the user equipment receives this first message.

[0081] In some alternative implementations, after generating the first message, the network device 10 may send the first message to the user equipment 20.

[0082] In a specific implementation, network device 10 can send the aforementioned first message via higher-layer information (such as RRC information). Alternatively, network device 10 can also trigger user equipment 20 to perform CSI measurement and reporting via downlink control information (DCI) carried by the physical downlink control channel (PDCCH). It should be understood that this application does not impose specific restrictions on the method by which network device 10 sends the first message.

[0083] Furthermore, user equipment 20 can receive the first message from network device 10.

[0084] S23, the user equipment receives a CSI report based on the first message.

[0085] In some feasible implementations, after receiving the first message, the user equipment 20 can parse the first message based on the corresponding communication protocol to extract the various configuration or resource information contained in the first message, such as the CSI report configuration information and CSI measurement resource information. Then, the user equipment 20 can perform corresponding CSI measurements based on the various configuration and resource information contained in the first message and further generate a corresponding CSI report.

[0086] In one alternative implementation, when the user equipment 20 extracts the target codebook type from the first message, it can be determined that a coherent joint transmission scheme should be used for subsequent CSI measurements.

[0087] In one optional implementation, when the user equipment 20 extracts CSI measurement resource information from the first message and determines that the CSI measurement resource information includes N1 channel measurement resources, it can measure parameters such as SNR or RSRP for each of the N1 channel measurement resources, and determine the results as the channel measurement results corresponding to each channel measurement resource. It should be noted that the channel measurement results mentioned here are not limited to the SNR or RSRP mentioned above, but may also include RSRQ, etc., and this application does not impose specific limitations on this.

[0088] Furthermore, when the user equipment 20 also extracts the first threshold from the first message, after measuring the measurement results corresponding to each of the N1 channel measurement resources, it can calculate the difference or absolute value of the channel measurement results corresponding to any two channel measurement resources. Then, the user equipment can filter out N3 channel measurement resources from the N1 channel measurement resources based on the difference or absolute value of the channel measurement results corresponding to any two channel measurement resources. Here, the difference or absolute value of the channel measurement results corresponding to any two channel measurement resources in these N3 channel measurement resources is less than or equal to the first threshold. Then, the user equipment 20 can determine that these N3 channel measurement resources are the channel measurement resources it needs to report, that is, its subsequent CSI report should contain the indication information corresponding to the above N3 channel measurement resources.

[0089] For example, suppose the aforementioned N1 channel measurement resources include channel measurement resource R1, channel measurement resource R2, channel measurement resource R3, and channel measurement resource R4, with corresponding indication information r1, r2, r3, and r4, and corresponding channel measurement results SNR1, SNR2, SNR3, and SNR4, respectively. If user equipment 20 determines that the differences between SNR1 and SNR2, SNR3, and SNR4 are all less than the aforementioned first threshold, the differences between SNR2 and SNR3 and SNR4 are all less than the first threshold, and the difference between SNR3 and SNR4 is greater than the aforementioned first threshold, then user equipment 20 can determine that channel measurement resources R1 and R2 are the channel measurement resources it needs to report, and its subsequent CSI report should include the two indication information r1 and r2.

[0090] Furthermore, if the user equipment 20 extracts one or more interference measurement resources associated with the CSI report configuration information from the aforementioned first message, and determines that there are N4 first channel measurement resources among the aforementioned N1 channel measurement resources, the user equipment 20 can perform interference measurement and obtain the corresponding interference measurement results based solely on the aforementioned N4 first channel measurement resources. The one or more interference measurement resources associated with the aforementioned CSI report configuration information may not be used. The description of the N4 first channel measurement resources can be found above and will not be repeated here.

[0091] Furthermore, when the user equipment 20 determines that the indication information corresponding to the above N1 channel measurement resources is included in the above CSI report (that is, when the above N4 first channel measurement resources do not exist), the user equipment 20 can perform interference measurement based on one or more interference measurement resources associated with the CSI report configuration information contained in the above first message and obtain the corresponding interference measurement results.

[0092] It should be understood that the preceding description only outlines some steps in the process of user equipment 20 performing CSI measurements based on the first message. In actual implementations, user equipment 20 may also complete other related measurement processes based on the first message, which will not be listed here.

[0093] After the user equipment 20 completes all CSI measurement processes and obtains the corresponding measurement results based on the aforementioned first message, it can further calculate the CSI report that needs to be reported based on these measurement results. Here, the CSI report includes the CSI calculated by the user equipment 20, and this CSI mainly includes one or more of the following: channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), SS / PBCH block resource indicator (SSBRI), layer indicator (LI), and rank indicator (RI). It should be noted that the specific content of the CSI report can be indicated by the CSI report configuration information included in the aforementioned first message; this application does not limit the specific content of the CSI report reported by the user equipment 20.

[0094] S24, the user equipment generates a second message containing a CSI report.

[0095] In some feasible implementations, after calculating the aforementioned CSI report, the user equipment 20 generates a second message containing the aforementioned CSI report.

[0096] S25, the user equipment sends a second message to the network device. Correspondingly, the network device receives the second message.

[0097] In some feasible implementations, after generating the second message, the user equipment 20 can send the second message back to the network equipment 10.

[0098] Optionally, user equipment 20 may send the second message to network device 10 via channels such as physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH).

[0099] Furthermore, network device 10 can receive a second message from user equipment 20 and extract the CSI report from the second message. Then, network device 10 can perform resource scheduling adjustments and / or beam management based on the CSI report. It should be understood that this application does not impose specific limitations on how network device 10 uses the CSI report.

[0100] In this embodiment, network device 10 configures user equipment 20 with target codebook type suitable for coherent joint transmission scheme and other relevant information for user equipment 20 to obtain CSI report through a first message, which solves the specific configuration and measurement problems of CSI measurement under coherent joint transmission scheme and is beneficial to the application of coherent joint transmission scheme.
