Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a wireless communication system according to an embodiment of the present disclosure. As shown in fig. 1, the wireless communication system mainly includes a network device 10 and a user equipment 20, and the network device 10 and the user equipment 20 implement uplink and downlink transmission of data or signaling by using a multi-site coherent joint transmission scheme. Specifically, the network device 10 may be composed of a plurality of stations, such as station 1, station 2 through station N shown in fig. 1. Here, N is a positive integer greater than or equal to. The N sites will cooperate to serve the user device 20. It should be understood that, for the user equipment 20, the N sites are equivalent to one network device 10, which is also for the network device 10 to transceive data or signaling. Hereinafter, for convenience of understanding and presentation, the above-described N sites will be collectively described as the network device 10.
It should be noted that the multi-station coherent joint transmission related to the present application may be joint coherent transmission of multiple stations, may also be different data belonging to the same Physical Downlink Shared Channel (PDSCH) and sent from different stations to the terminal device, and may also be virtual transmission performed by forming one station for multiple stations. It should be understood that the same names defined in other standards are also applicable to the present application, i.e., the present application does not limit the names of these scenarios.
In practical implementation, the stations (e.g., the station 1 to the station N) referred to in this application may be Radio Remote Heads (RRHs) and/or Transmission Reception Points (TRPs). In other words, the coherent joint transmission scheme according to the present application can be implemented based on multiple remote radio heads RRH or multiple transmission and reception points TRP. Here, the transmission reception point TRP may be specifically a Base Station (BS). A so-called base station is a device deployed in a radio access network to provide wireless communication functions. For example, a device providing a base station function in a 2G network includes a Base Transceiver Station (BTS) and a Base Station Controller (BSC), a device providing a base station function in a 3G network includes a node B (NodeB) and a Radio Network Controller (RNC), a device providing a base station function in a 4G network includes an evolved node B (eNB), a device providing a base station function in a Wireless Local Area Network (WLAN) is an Access Point (AP), a device providing a base station function in a 5G New Radio (New Radio, NR) includes a node B (gNB) that continues to evolve, and a device providing a base station function in a future New communication system, and the like. The specific implementation form of the station is not limited in the application.
The user equipment to which the present application relates may be any of a variety of devices that provide voice and/or data connectivity to a user, such as a handheld device having wireless connectivity capabilities or a processing device connected to a wireless modem. For example, mobile phones (or so-called "cellular" phones), computers with mobile terminals, portable, pocket, hand-held, computer-included or vehicle-mounted mobile devices, smart wearable devices, and the like may be included. For example, personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), smartbands, smartwatches, and the like. Also included are constrained devices such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Also, for example, information sensing devices include bar codes, radio Frequency Identification (RFID), sensors, global Positioning Systems (GPS), laser scanners, and the like. In addition, the chip applied to the above device may also be referred to as a user equipment. The specific implementation form of the user equipment is not particularly limited in the present application.
In addition, the wireless communication system may specifically be a 5G (5 generation) communication system supporting a coherent joint transmission scheme, may also be a 2G, 3G, or 4G communication system supporting a coherent joint transmission scheme, may also be a satellite communication system supporting a coherent joint transmission scheme, and may also be various communication systems supporting subsequent evolution of a coherent joint transmission scheme, for example, 6G,7G, and the like, which is not limited in this application.
Since specific configuration information on channel state information, CSI, measurements has not been proposed in the prior art for the wireless communication system shown in fig. 1. Therefore, an object of the present invention is to provide a method for processing CSI measurement in a coherent joint transmission scheme, so as to improve applicability and practicability of the coherent joint transmission scheme in a wireless communication system.
Referring to fig. 2, fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in fig. 2, the method comprises the steps of:
s21, the network equipment generates a first message containing CSI report configuration information.
In some alternative implementations, when network device 10 determines that user equipment 20 is required to perform CSI measurements, network device 10 may generate a first message containing at least CSI reporting configuration information. Here, the first message may be used for CSI measurement and reporting by the user equipment 20. The CSI report configuration information at least includes a target codebook type, and the target codebook type is a codebook type of a coherent joint transmission scheme. In other words, the target codebook type may be a codebook type under the assumption of a coherent joint transmission scheme. It should be noted that the target codebook type is a codebook type of a coherent joint transmission scheme, and it is understood that the target codebook type is applicable to a joint coherent transmission scheme.
In a specific implementation, in a case where wireless communication with the user equipment 20 is planned or determined to employ a coherent joint transmission scheme, the network device 10 may generate CSI report configuration information applicable to the user equipment 20 based on network state information between the network device and the user equipment 20 and a preset CSI configuration rule. This CSI report configuration information is mainly used to inform the ue 20 how to report the CSI report obtained by the ue based on the first message. In particular, since a coherent joint transmission scheme is adopted, the CSI report configuration information at least includes a target codebook type of the coherent joint transmission scheme, so that the target codebook type is included in CSI reports reported by subsequent user equipments 20.
Illustratively, the target codebook type may be a codebook type such as typeII-r18, typeII-PortSelection-r18, typeI-MultiPanel-r18, typeI-r18, etc. suitable for the coherent joint transmission scheme. It should be understood that the foregoing is only an exemplary expression of the target codebook type, and in practical use, the target codebook type may also be any other codebook type suitable for the coherent joint transmission scheme, and the present application does not specifically limit this.
In an optional implementation manner, the CSI report configuration information may include codebook configuration information, and the target codebook type may be included in the codebook configuration information.
In an alternative implementation, the target codebook type may also be used as an indicator to inform the user equipment 20 that CSI measurement should be performed based on the coherent joint transmission scheme assumption, so as to obtain the CSI report. In other words, when the user equipment 20 extracts the target codebook type from the CSI report configuration information, it can be determined that it should perform CSI measurement based on the coherent joint transmission scheme assumption, so as to obtain a CSI report.
Therefore, it can be understood that the CSI report reported by the subsequent ue contains a codebook, and the codebook type of the codebook is the target codebook type. It should be noted that the CSI report includes a codebook, and may be understood that the CSI report reported by the user 20 includes a PMI, may be understood that the CSI report includes a codebook indicated by the PMI, may be understood that the CSI report includes a PMI belonging to the codebook, may be understood that the CSI report includes a codebook indication, may be understood that the CSI report includes a precoding matrix indicated by the PMI belonging to the codebook, may be understood that the CSI report includes a PMI indicating the codebook, and may be understood that the CSI report includes a PMI indicating the precoding matrix belonging to the codebook.
In an optional implementation manner, the first message may further include CSI measurement resource information, and the CSI measurement resource information includes N1 channel measurement resources. Here, N1 is a positive integer greater than or equal to 1. The N1 channel measurement resources may be used for CSI measurement and calculation by the subsequent ue 20. Optionally, each of the N1 channel measurement resources may specifically be information such as a time domain resource and a frequency domain resource corresponding to an SSB or a CSI reference signal (i.e., CSI-RS).
Further, the CSI measurement resource information may include N2 channel measurement resource sets, where each of the N2 channel measurement resource sets includes one or more channel measurement resources, and the total number of the channel measurement resources included in the N2 channel measurement resource sets is N1. N2 is a positive integer greater than or equal to 1. In other words, the N1 channel measurement resources exist in the CSI measurement resource information in the form of N2 channel measurement resource sets, and one or more of the N1 channel measurement resources constitute one channel measurement resource set.
Furthermore, the total number of the ports of one or more channel measurement resources included in any one of the N2 channel measurement resource sets should be less than or equal to 32. For example, assuming that the channel measurement resource set a in the N2 channel measurement resource sets includes 5 channel measurement resources, the total number of ports to which the 5 channel measurement resources are assigned should not exceed 32.
Still alternatively, the total number of ports of one or more channel measurement resources included in one part of the N2 channel measurement resource sets should be less than or equal to 32, and the total number of ports of each channel measurement resource in another part of the N2 channel measurement resource sets may not be specifically limited.
In an alternative implementation, the first message may further include a preset threshold (for convenience of distinction, the first threshold is used instead of the description below). This first threshold may be used to determine indication information of channel measurement resources included in a CSI report reported by the ue. For example, assuming that the CSI report reported by the ue includes indication information of N3 channel measurement resources, a difference value or an absolute value of the difference value of channel measurement results corresponding to any two channel measurement resources of the N3 channel measurement resources is less than or equal to the first threshold. Here, the N3 channel measurement resources are some or all of the N1 channel measurement resources described above, that is, N3 is less than or equal to N1.
It should be noted that the indication information of the channel measurement resource related to the present application is information capable of uniquely indicating the channel measurement resource, and the indication information may be information in any implementation form, such as binary numbers and symbols with different values.
Optionally, the measurement result corresponding to the channel measurement resource may specifically be a Reference Signal Received Power (RSRP), a Reference Signal Received Quality (RSRQ), a signal to noise ratio (SNR), and other parameters measured by the user equipment 20 on the channel measurement resource, which is not limited in this application.
In an optional implementation manner, the CSI measurement resource information may not include an interference measurement resource associated with the CSI report configuration information. Here, the interference measurement resource may be specifically a CSI interference measurement resource (i.e., (CSI-interference measurement, CSI-IM)).
It should be understood that the CSI measurement resource information may not include the interference measurement resource associated with the CSI report configuration information, and it is understood that the CSI measurement resource information may not include the interference measurement resource.
In an optional implementation manner, the CSI measurement resource information may include one or more interference measurement resources associated with the CSI report configuration information.
It should be understood that the CSI measurement resource information may include one or more interference measurement resources associated with the CSI report configuration information, and it should be understood that the CSI measurement resource information may include one or more interference measurement resources.
Similarly, the one or more interference measurement resources (assumed to be N6) may also exist in the CSI measurement resource information in the form of an interference measurement resource set. Here, N6 is a positive integer greater than or equal to 1. That is to say, in a specific implementation, the CSI measurement resource information may include one or more interference measurement resource sets, and each interference measurement resource set may include one or more interference measurement resources, where the total number of interference measurement resources included in the one or more interference measurement resource sets is N6.
In an optional implementation manner, the N1 channel measurement resources include N4 first channel measurement resources, and the N4 first channel measurement resources may be used as interference measurement resources. Here, the N4 first channel measurement resources are channel measurement resources other than the N5 second channel measurement resources among the above N1 channel measurement resources. The indication information of the N5 second channel measurement resources is included in the CSI report reported by the ue 20.
For example, it is assumed that the N1 channel measurement resources include a channel measurement resource R1, a channel measurement resource R2, a channel measurement resource R3, and a channel measurement resource R4, and the corresponding indication information is R1, R2, R3, and R4, respectively. If the ue 20 subsequently determines that the channel measurement resource R2, the channel measurement resource R3, and the channel measurement resource R4 are channel measurement resources that need to be reported, that is, the CSI report that is subsequently sent includes the indication information R2, R3, and R4, the channel measurement resource R2, the channel measurement resource R3, and the channel measurement resource R4 are second channel measurement resources, and the channel measurement resource R1 is the first channel measurement resource. Therefore, in the subsequent CSI measurement process, the user equipment 20 may perform interference measurement by using the channel measurement resource R1 as an interference measurement resource.
Here, when the first message includes the first threshold, the N5 second channel measurement resources are equivalent to the N3 channel measurement resources described above. And under the condition that the first message does not include the first threshold, the N5 second channel measurement resources may be the channel measurement resources that need to be reported and are determined by the ue 20 from the N1 channel resources through other preset rules. The method for determining the N5 second channel measurement resources by the user equipment 20 is not particularly limited in the present application.
In some optional implementations, when the N1 channel measurement resources include the N4 first channel measurement resources, if the CSI measurement resource information also includes one or more interference measurement resources associated with the CSI report configuration information, the one or more interference measurement resources may not be used for CSI measurement performed by the user equipment 20. That is, in a case where N4 first channel measurement resources coexist with one or more interference measurement resources associated with the CSI reporting configuration information, the user equipment 20 may perform interference measurement by using only the N4 first channel measurement resources as interference measurement resources to obtain an interference measurement result required for generating a CSI report.
In some optional implementations, if the CSI measurement resource information also includes one or more interference measurement resources associated with the CSI report configuration information, the one or more interference measurement resources may also be used for CSI measurement performed by the user equipment 20.
S22, the network equipment sends a first message to the user equipment. Correspondingly, the user equipment receives the first message.
In some alternative implementations, after generating the first message, the network device 10 may send the first message to the user device 20.
In a specific implementation, the network device 10 may send the first message through higher layer information (e.g., RRC information). Alternatively, the network device 10 may also trigger the ue 20 to perform CSI measurement and reporting through Downlink Control Information (DCI) carried by a Physical Downlink Control Channel (PDCCH). It should be understood that the present application is not particularly limited as to the manner in which the network device 10 sends the first message.
Further, the user device 20 may receive the first message from the network device 10.
And S23, the user equipment obtains the CSI report based on the first message.
In some possible implementations, after receiving the first message, the ue 20 may parse the first message based on a corresponding communication protocol to extract configuration information or resource information included in the first message, such as the CSI report configuration information, the CSI measurement resource information, and the like. Then, the ue 20 may perform the CSI measurement based on the configuration information and the resource information included in the first message, and further generate the CSI report.
In an alternative implementation, when the user equipment 20 extracts the target codebook type from the first message, it may be determined that CSI measurement should be performed subsequently using the coherent joint transmission scheme hypothesis.
In an optional implementation manner, 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, the N1 channel measurement resources may be measured for parameters such as SNR or RSRP, respectively, and the obtained result is determined as a channel measurement result corresponding to each channel measurement resource. It should be noted that the channel measurement result described herein is not limited to the SNR or RSRP described above, and may also include RSRQ, etc., which is not specifically limited in this application.
Further, when the ue 20 further extracts the first threshold from the first message, after measuring the measurement result corresponding to each of the N1 channel measurement resources, it may respectively calculate a difference value or an absolute value of the difference value of the channel measurement results corresponding to any two channel measurement resources. Then, the ue may screen N3 channel measurement resources from the N1 channel measurement resources based on a difference value or an absolute value of the difference value of the channel measurement results corresponding to any two channel measurement resources in the N1 channel measurement resources. Here, the difference value of the channel measurement results corresponding to any two of the N3 channel measurement resources or the absolute value of the difference value is less than or equal to the first threshold. Then, the ue 20 may determine that the N3 CSI resources are the CSI resources that need to be reported, that is, the CSI report that is reported subsequently should include indication information corresponding to the N3 CSI resources.
For example, it is assumed that the N1 channel measurement resources include a channel measurement resource R1, a channel measurement resource R2, a channel measurement resource R3, and a channel measurement resource R4, the corresponding indication information is R1, R2, R3, and R4, and the corresponding channel measurement results are SNR1, SNR2, SNR3, and SNR4, respectively. If the user equipment 20 determines that the differences between SNR1 and SNR2, SNR3, and SNR4 are smaller than the first threshold, the differences between SNR2 and SNR3, and SNR4 are smaller than the first threshold, and the differences between SNR3 and SNR4 are greater than the first threshold, the user equipment 20 may determine that the channel measurement resource R1 and the channel measurement resource R2 are channel measurement resources that need to be reported, and a CSI report subsequently reported by the user equipment should include two pieces of indication information, namely R1 and R2.
Further, in the case that the user equipment 20 extracts one or more interference measurement resources associated with the CSI report configuration information from the first message, and determines that N4 first channel measurement resources exist in the N1 channel measurement resources, the user equipment 20 may perform interference measurement based on only the N4 first channel measurement resources and obtain corresponding interference measurement results. One or more interference measurement resources associated with the CSI reporting configuration information may not be used. Here, the description of the N4 first channel measurement resources may be referred to in the foregoing, and will not be described herein again.
Further, when the ue 20 determines that the indication information corresponding to the N1 channel measurement resources is all included in the CSI report (that is, when the N4 first channel measurement resources do not exist), the ue 20 may perform interference measurement based on one or more interference measurement resources associated with the CSI report configuration information included in the first message, and obtain a corresponding interference measurement result.
It should be understood that the foregoing is only a partial step in the CSI measurement process performed by the ue 20 based on the first message. In practical implementation, the user equipment 20 may also complete other related measurement processes based on the first message, which is not illustrated in this application.
After the ue 20 completes all CSI measurement processes based on the first message and obtains corresponding measurement results, the CSI report to be reported may be further obtained by calculation based on the measurement results. Here, the CSI report includes CSI calculated by the ue 20, and the CSI mainly includes one or more of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS resource indicator (CRI), an SSB resource indicator (SSB/PBCH resource indicator, ssri), a Layer Indicator (LI), and a Rank Indicator (RI). It should be noted that, specific contents included in the CSI report may be indicated by the CSI report configuration information included in the first message, and the specific contents included in the CSI report reported by the ue 20 are not limited in this application.
And S24, the user equipment generates a second message containing the CSI report.
In some possible implementations, the ue 20 generates the second message including the CSI report after calculating the CSI report.
And S25, the user equipment sends a second message to the network equipment. Correspondingly, the network device receives the second message.
In some possible implementations, the user equipment 20 may feed the second message back to the network device 10 after generating the second message.
Optionally, the user equipment 10 may send the second message to the network equipment 10 through a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), and other channels.
Further, the network device 10 may receive a second message from the user equipment 20, and extract the CSI report from the second message. Then, the network device 10 may perform operations such as adjustment of resource scheduling and/or beam management based on the CSI report. It should be understood that the present application is not particularly limited as to how the network device 10 uses the above-described CSI reporting process.
In the embodiment of the present application, the network device 10 configures, through the first message, the target codebook type suitable for the coherent joint transmission scheme and other relevant information for the user equipment 20 to obtain the CSI report for the user equipment 20, so as to solve the specific configuration and measurement problem of CSI measurement in the coherent joint transmission scheme, and facilitate application of the coherent joint transmission scheme.
