Method, device and system for indicating the measurement purpose of channel state information
Technical field
[0001]
The present invention relates to the field of communications, and in particular to a method, device and system for indicating the measurement purpose of channel state information.
Background technique
[0002]
In high-frequency or low-frequency communication scenarios, to improve communication transmission throughput and reduce communication delay, accurate channel measurement techniques are required. In the new wireless (5G-NR, 5 generation-new radio) system of the fifth-generation mobile communication technology, a flexible channel state information (CSI) measurement and reporting mechanism can meet the needs of different scenarios, especially high-frequency communications. Scenario, the need for precise CSI. Generally speaking, network equipment usually configures CSI measurement resources to allow terminal equipment to measure CSI in corresponding resources. At the same time, the network device needs to let the terminal device know which CSI calculation results need to be fed back.
[0003]
In the existing technology, the 5G-NR system can indicate the purpose of CSI measurement. That is, by indicating the number of CSI measurement resources corresponding to the CSI report resource, the terminal device can learn the measurement purpose of the CSI measurement resource, so as to perform corresponding calculation feedback. Figure 1 shows three different measurement feedbacks. As shown in Figure 1, when a CSI Report Setting Configuration (CSI-Report) is associated with a Resource Setting, for example, When CSI-Report is associated with Channel Measurement Resource (CMR, Channel Measurement Resource), the Resource Setting (such as CMR) is used for layer 1 reference signal received power (L1-RSRP) channel measurement; when a CSI Report Setting Configuration is associated with When more than one Resource Setting is associated, for example: CSI-Report is associated with CMR and interference measurement resource (IMR) based on non-zero power CSI reference signal (NZP-CSI-RS based) (NZP-IMR for short), or CSI-Report is associated with CMR and ZP-CSI-RS based Interference Measurement Resource (IMR) (referred to as ZP IMR), or CSI-Report is associated with CMR, NZP IMR and NP IMR When connecting, the first Resource Setting (such as CMR) is used for channel measurement instead of L1-RSRP measurement, and the other Resource Setting (such as NZI-IMR and/or ZP-IMR) is used for interference measurement.
[0004]
It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present invention, and to facilitate the understanding of those skilled in the art. It should not be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention.
[0005]
Summary of the invention
[0006]
The inventor found that when communicating in a high frequency band, only relying on L1-RSRP-based channel measurement feedback, the communication system cannot successfully perform beam management in a strong interference environment. In order to enable the beam management of the high frequency band to better handle interference, a channel measurement feedback mechanism based on L1-SINR is indispensable. It can effectively make up for the deficiencies of existing mechanisms.
[0007]
However, when L1-SINR is added as a new CSI reporting indicator to the framework of CSI measurement reporting, the existing mechanism of the 5G-NR system cannot determine the measurement purpose of the CSI resource in some cases. As shown in Figure 2, when one CSI Report Setting Configuration is associated with more than one Resource Setting, the terminal device cannot determine the purpose of these Resource Setting. The reason is that both L1-SINR-based beam management measurement and general channel measurement (non-L1-SINR) may configure channel measurement resources (CMR) and interference measurement resources (IMR) at the same time. If the terminal device cannot distinguish the measurement purpose corresponding to the CSI measurement resource, the following two situations may occur:
[0008]
1) The terminal equipment uses the reference signal used for L1-SINR measurement for general channel measurement. This will not only lead to a sharp increase in CSI calculation complexity, but also may lead to inaccurate CSI estimation results.
[0009]
2) The terminal equipment uses the reference signal used for general channel measurement for L1-SINR measurement. This will lead to inaccurate CSI estimation results.
[0010]
In addition, for measurement reference signals of different purposes, the CSI calculation resources occupied by them are also different. For example, when L1-SINR-based beam management is adopted, the computing resources occupied by its corresponding measurement resources are not clear, which will make it impossible for terminal equipment and network equipment to achieve the amount of CSI computing resources occupied within a certain period of time. Consensus, which causes the number of CSI measurements or calculations configured by the network equipment for the terminal equipment to exceed the computing capacity of the terminal equipment, which affects the system performance.

[0222]
That is to say, the CSI measurement resource used for channel measurement in the second CSI measurement resource set includes only CSI-RS or only SSB, then the difference between the CSI measurement resource (CSI-RS or SSB) and the corresponding interference measurement resource The relationship is QCL Type-C and/or QCL Type-D.

The above-mentioned Z 1 is the CSI calculation time related to the CSI measurement resource.
[0271]
The above-mentioned Z 0 is related to the subcarrier interval, and/or is related to the calculation purpose and/or reported content (L1-RSRP, L1-SINR, L1-RSRQ) corresponding to the above-mentioned CSI report set, for example, when the calculation purpose is L1- For RSRP, for the value of Z 0 , when the sub-carrier spacing is 15 kHz, Z 0 = 22 symbols; when the sub-carrier spacing is 30 kHz, Z 0 = 33 symbols; when the sub-carrier spacing is 60 kHz, Z 0 =min(44, Z 1 +KB1) symbols; when the sub-carrier spacing is 120kHz, Z 0 =min(97, Z 1 +KB2) symbols. Among them, KB1 and KB2 are related to the ability of the terminal device to report to the network side. This capability refers to the time required for the terminal device to receive the corresponding PDSCH after receiving the PDCCH until the space (QCL) information indicated by the PDCCH is applied. For example, at 60kHz, KB1={7,14,28}; at 120kHz, KB2={14,28}. When the calculation purpose is L1-SINR, the value of Z 0 is greater than (when the calculation purpose is L1-RSRP or L1-RSRQ) the value of Z 0 . This is because the calculation complexity of L1-SINR is higher than that of L1-RSRP or L1-RSRQ, so the required CSI calculation time is longer.
[0272]
The above Z 1 is related to the ability of the terminal device to report to the network side. This capability means that the terminal device reports different reporting processing times related to beam management to the network side according to different subcarrier intervals. Wherein, the aforementioned reporting processing time for calculating beam management related may refer to the calculation purpose (L1-RSRP, L1-SINR, L1-RSRQ) corresponding to the aforementioned CSI reporting set.
[0273]
The foregoing channel measurement resource or interference measurement resource may be used for L1-SINR measurement, for example, may be one of CSI-RS, SSB, and CSI-IM. At the same time, the period of the foregoing channel measurement resource and interference measurement resource (if there is interference measurement resource) used for L1-SINR measurement may be the same. The advantage of the same period of these resources is that it can ensure the fairness and accuracy of the joint estimation result through channel measurement and interference measurement.
[0274]
Figure 15 shows two examples of the CPU time T occupied by the corresponding CSI measurement when a CSI report set is aperiodic. As shown on the left side of Figure 15, x+Z 0 y+Z 1 , Then the CPU time T occupied by the corresponding CSI measurement is the first symbol after the PDCCH that triggers the CSI report to x+Z 0 .
[0275]
For another example: if the time domain behavior corresponding to the above CSI report set is periodic, the CPU time (T) occupied by the CSI measurement corresponding to the CSI report set is: from the time associated with the CSI report set The first symbol of the earliest measurement opportunity in the measurement opportunity of the CSI measurement resource related to the CSI report set in a transmission opportunity reaches y'+Z 1 . The meaning of Z 1 is the same as the foregoing, and y'is the last symbol of the latest measurement opportunity among the transmission opportunities of the CSI measurement resources related to the CSI report set in the above transmission opportunities. The aforementioned CSI measurement resource may be a resource used for CSI channel measurement, and may also be a resource used for interference measurement.
[0276]
Figure 16 shows an example of the CPU time T occupied by CSI measurement when a CSI report set is periodic. As shown in Figure 16, in transmission opportunity #1 or transmission opportunity #N, the CPU occupancy time It is from resource #1 to resource #3+Z 1 , resource #1 is the earliest measurement opportunity (the first symbol), and resource #3 is the latest measurement opportunity (the first or last symbol).
[0277]
For another example: if the time domain behavior corresponding to the above CSI report set is semi-continuous, and the first (initial) CSI measurement corresponding to the CSI report set is triggered by the downlink control information (PDCCH), then the CSI In terms of measurement, the CPU time (T) it occupies is: from the first symbol after the downlink control information (PDCCH) that triggered the CSI report set to the maximum value of x+Z 0 and y+Z 1 . The meanings of x, Z 0 , y, and Z 1 are the same as described above.
[0278]
Figures 17 and 18 show two examples of the time T occupied by the CSI measurement corresponding to the CSI reporting set in the case of a semi-persistent CSI reporting set triggered by the PDCCH. In the example of Figure 17, x +Z 0 y+Z 1 , then the CPU time T occupied by CSI measurement is the first symbol after triggering the PDCCH reported by the CSI to x+Z 0 .
[0279]
For another example: if the time domain behavior corresponding to the above CSI report set is semi-continuous, except for the related CSI measurement triggered by the PDCCH for the first time (initial), the CPU time occupied by the CSI measurement corresponding to the CSI report set (T) is: from the first symbol of the earliest measurement opportunity among the measurement opportunities of the CSI measurement resource related to the CSI report set to y'+Z 1 . The meanings of y'and Z 1 are the same as described above. The aforementioned CSI measurement resource may be a resource used for CSI channel measurement, and may also be a resource used for interference measurement.
[0280]
Fig. 19 shows an example of the time T occupied by the CSI measurement corresponding to the CSI report set in the case of the semi-persistent CSI report set triggered by the MAC-CE. In this example, as shown in Fig. 19, for each A transmission opportunity, the CPU occupancy time T is from resource #1 to resource #2+Z 1 , resource #1 is the earliest measurement opportunity (the first symbol), and resource #2 is the latest measurement Opportunity (the first symbol of). As shown in Figure 17 and Figure 18, except for the transmission opportunity (the first transmission opportunity) corresponding to the related CSI measurement triggered by the PDCCH for the first time, for each other transmission opportunity, the CPU occupancy time T is the slave resource# 1 to resource #2+Z 1 , resource #1 is the earliest measurement opportunity (the first symbol) of the transmission opportunity, and resource #2 is the latest measurement opportunity (the last symbol) of the transmission opportunity .
