Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a CSI reporting method, a terminal and a network-side device, an electronic device and a medium. Background Art

[0002] In the SubBand non-overlapping FullDuplex (SBFD) technology, the downlink resources available to the terminal are different in different time slot types. For example, in the SBFD time slot, the terminal can only use the frequency domain resources of the DL (Down Link) subband for downlink reception (not the full downlink bandwidth). In the non-SBFD time slot, the terminal can perform downlink reception on the DL BWP (Bandwidth Part) with a larger frequency domain resource range, such as the full downlink bandwidth. The downlink power in the SBFD time slot and the non-SBFD time slot may also be different. In addition, the interference conditions in the SBFD time slot and the non-SBFD time slot are also different. The terminal will be affected by the CLI (Cross Link Interference) of other terminals in the SBFD time slot.

[0003] For a periodic or semi-persistent CSI-RS (Channel State Information-ReferenceSignal), its time domain position may appear in an SBFD time slot and a non-SBFD time slot. If the existing CSI reporting method is used, the terminal will average multiple measurement results on the periodic or semi-persistent CSI-RS (that is, average the measurement results of the same CSI-RS measured in the SBFD time slot and the non-SBFD time slot) before reporting, resulting in the base station being unable to distinguish the true channel state information.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1 , Figure 1 : is a flow chart of a method for reporting channel state information CSI provided in an embodiment of the present application, which is applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0024] Step 101, receiving a CSI reporting configuration configured by a network side device, wherein the CSI reporting configuration includes at least one of the following configurations: a channel measurement resource CMR (Channel Measurement Resource), two CSI IM (Interference Measurement) resources for interference measurement, and one or two reporting resources; the time domain position of the channel measurement resource includes at least one of the following types: a first time type and a second time type;

[0025] Optionally, the first time type in the embodiment of the present application includes at least one of the following: sub-band full-duplex SBFD time slots and / or symbols, time slots and / or symbols configured with uplink frequency domain resources and / or downlink frequency domain resources. The second time type includes at least one of the following: non-SBFD time slots and / or symbols, time slots and / or symbols not configured with uplink frequency domain resources and / or downlink frequency domain resources.

[0026] Step 102: Perform CSI reporting based on the CSI reporting configuration;

[0027] It can be known from the above steps 101 and 102 of the embodiment of the present application that in the embodiment of the present application, the terminal can receive the CSI reporting configuration configured by the network side device, based on the CSI reporting configuration, wherein the CSI reporting configuration includes at least one of the following configurations: one channel measurement resource, two CSI IM resources for interference measurement, one or two reporting resources; the time domain position of the channel measurement resource includes at least one of the following types: the first time type, the second time type. The terminal can measure the reference signal at the corresponding different time types (the first time type and the second time type), that is, two measurement results (the first measurement result and the second measurement result) can be obtained, and the two measurement results can be reported based on one or two reporting resources, rather than averaging the two measurement results and then reporting them, thereby solving the problem that the terminal in the prior art averages the CSI-RS measurement results on different time types, that is, averages the measurement results of the periodic or semi-continuous CSI-RS on different time types and then reports them, resulting in the base station being unable to distinguish the true channel state information.

[0028] In an optional implementation manner of an embodiment of the present application, when the time domain position of the channel measurement resource includes a first time type and a second time type, the manner of performing CSI reporting based on the CSI reporting configuration involved in the above step 102 may further include:

[0029] Step 11, measuring a reference signal at a first time type and a second time type respectively, to obtain a first measurement result corresponding to the first time type and a second measurement result corresponding to the second time type;

[0030] Step 12: Report the first measurement result and the second measurement result based on one reporting resource, or report the first measurement result and the second measurement result respectively based on two reporting resources.

[0031] It can be seen that in the embodiment of the present application, if there is only one reporting resource currently, the two measurement results obtained based on the measurement of different time types (the first time type and the second event type) are reported separately, rather than averaging the two measurement results for reporting, that is, the network side device can distinguish the corresponding measurement results. If there are two reporting resources currently, the two measurement results are reported separately based on the two reporting resources. Since one measurement result is reported by one reporting resource, it is easier for the network side to distinguish the corresponding measurement results. It should be noted that the first time type in the embodiment of the present application may be an SBFD time slot and / or SBFD symbol, and the second time type is a non-SBFD time slot and / or SBFD symbol; or, if the first time type is a time slot and / or symbol configured with uplink frequency domain resources (uplink subband) and / or downlink frequency domain resources (downlink subband), the second time type is a time slot and / or symbol not configured with uplink frequency domain resources (uplink subband) and / or downlink frequency domain resources (downlink subband).

[0032] In the embodiment of the present application, when the CSI reporting configuration includes two CSI IM resources for interference measurement, the manner of performing CSI reporting based on the CSI reporting configuration involved in the above step 102 may further include:

[0033] Step 21: obtaining a third measurement result corresponding to the first CSI IM resource and a fourth measurement result corresponding to the second CSI IM resource based on the two CSI IM resources; wherein the two CSI IM resources for interference measurement include the first CSI IM resource and the second CSI IM resource;

[0034] Step 22: report the third measurement result and the fourth measurement result based on one reporting resource; or, report one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result based on one reporting resource; or, report the third measurement result and the fourth measurement result respectively based on two reporting resources.

[0035] It can be seen that in the embodiment of the present application, for the two measurement results (the third measurement result and the fourth measurement result) obtained based on the two CSI IM resources for interference measurement, the two measurement results can be reported based on one reporting resource, rather than averaging the two measurement results for reporting, or they can be reported separately based on the two reporting resources. Since one measurement result is reported by one reporting resource, it is easier for the network side to distinguish the corresponding measurement results.

[0036] In an optional implementation manner of the embodiment of the present application, for the manner of reporting the first measurement result and the second measurement result based on one reporting resource involved in the above step 12, the packet may include at least one of the following:

[0037] Step 31, reporting first information for identifying a first measurement result and the first measurement result, and second information for identifying a second measurement result and the second measurement result;

[0038] Step 32: reporting the first measurement result and the second measurement result based on a protocol predefined order, wherein the protocol predefined order refers to the order of the first measurement result and the second measurement result in the reporting information of the terminal;

[0039] It can be seen that in the embodiment of the present application, even if the current reporting is based on one reporting resource, it is possible to partition which is the first measurement result and which is the second measurement result by carrying information corresponding to different measurement results. In addition, the protocol predefined order in the specific example refers to first reporting the first measurement result based on one reporting resource and then reporting the second measurement result based on one reporting resource; or, the protocol predefined order refers to first reporting the second measurement result based on one reporting resource and then reporting the first measurement result based on one reporting resource. It can be seen that if the reporting order is known in advance, it can be determined whether the currently received measurement result is the first measurement result or the second measurement result according to the receiving order.

[0040] In this regard, in the case where there is only one reporting resource in the embodiment of the present application, the above steps 31 and 32 can be in a specific example: the CSI content reported by the terminal carries a flag (identifier) ​​and a measurement result, such as 0SINR#1, 1SINR#2, where "0" and "1" are flags, which are used to represent whether the time type corresponding to the signal to interference plus noise ratio (SINR) measurement result is the first time type or the second time type. Among them, "0" and "1" are the first information and the second information, and whether the first information is 0 or 1 can be set accordingly according to actual needs.

[0041] As for the protocol pre-definition, it is pre-defined that the terminal first reports the measurement result on the first time type, and then reports the measurement result on the second time type, for example, the terminal reports SINR#1, SINR#2, SINR#1 corresponds to the measurement result on the first time type, and SINR#2 corresponds to the measurement result on the second time type. Or it is pre-defined that the terminal first reports the measurement result on the second time type, and then reports the measurement result on the first time type, for example, the terminal reports SINR#1, SINR#2, SINR#1 corresponds to the measurement result on the second time type, and SINR#2 corresponds to the measurement result on the first time type.

[0042] In an optional implementation manner of an embodiment of the present application, for the method of reporting the first measurement result and the second measurement result based on two reporting resources involved in the above step 12, it can further include: reporting the first measurement result in one of the two reporting resources, and reporting the second measurement result in another reporting resource of the two reporting resources except the reporting resource for reporting the first measurement result; wherein the correspondence between the two reporting resources and the first measurement result and the second measurement result is predefined by the network side device configuration or the protocol.

[0043] In this regard, in a specific example, when there are two reporting resources in an embodiment of the present application, the network side device is configured or the protocol is predefined, and the terminal reports the measurement results of the first time type on reporting resource #1 (physical uplink control channel (Physical Uplink Control Channel, PUCCH) #1), and then reports the measurement results of the second time type on reporting resource #2 (PUCCH #2), or the terminal reports the measurement results of the second time type on reporting resource #1 (PUCCH #1), and reports the measurement results of the first time type on reporting resource #2 (PUCCH #2).

[0044] In an optional implementation manner of the embodiment of the present application, the manner of reporting the third measurement result and the fourth measurement result based on one reporting resource involved in the above step 22 includes one of the following:

[0045] Step 41: reporting the third information for identifying the third measurement result and the third measurement result, and the fourth information for identifying the fourth measurement result and the fourth measurement result;

[0046] Step 42: reporting the third measurement result and the fourth measurement result based on a protocol predefined order, wherein the protocol predefined order refers to the order of the third measurement result and the fourth measurement result in the reporting information of the terminal;

[0047] And the method of reporting one of the third measurement result and the fourth measurement result and the difference between the third measurement result and the fourth measurement result based on one reporting resource involved in the above step 22 includes:

[0048] Step 43: Report one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result based on a protocol predefined order, wherein the protocol predefined order refers to the order of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result in the reporting information of the terminal.

[0049] In a specific example, when there is only one reporting resource in the embodiment of the present application, the above steps 41 and 42 in the specific example can be: the CSI content reported by the terminal carries a flag (identifier) ​​+ measurement result, for example, 0SINR#1, 1SINR#2, where "0" and "1" are flags, which are used to respectively represent whether the time type corresponding to the SINR measurement result is the measurement result of CSI-IM resource #1 or the measurement result of CSI-IM resource #2.

[0050] For protocol pre-definition, it can be pre-defined that the terminal first reports the measurement result on CSI-IM resource #1, and then reports the measurement result on CSI-IM resource #2, so the terminal reports SINR #1, SINR #2, then SINR #1 corresponds to the measurement result on CSI-IM resource #1, and SINR #1 corresponds to the measurement result on CSI-IM resource #2; or, it is pre-defined that the terminal first reports the measurement result on CSI-IM resource #2, and then reports the measurement result on CSI-IM resource #1, so the terminal reports SINR #1, SINR #2, then SINR #1 corresponds to the measurement result on CSI-IM resource #2, and SINR #1 corresponds to the measurement result on CSI-IM resource #1. In this regard, in an SBFD system, CSI-IM resource #1 may only include inter-cell interference measurement, and no other terminal sends uplink, while on CSI-IM resource #2, there are other terminals sending uplink, including both inter-cell interference measurement and cross-link interference measurement between terminals. Based on this, the network side device obtains the measurement results on the two CSI-IM resources and knows the interference situation between terminals in the SBFD time slot.

[0051] For the above step 43, in a specific example, if the terminal reports the measurement result on CSI-IM resource #1, it also reports the difference between the measurement result on CSI-IM resource #1 and the measurement result on CSI-IM resource #2. If in the SBFD system, CSI-IM resource #1 only includes interference measurement between cells, and no other terminal sends uplink, and CSI-IM resource #2 has other terminals sending uplink, it includes both interference measurement between cells and cross-link interference measurement between terminals. Therefore, when the network-side device obtains the difference in measurement results on these two CSI-IM resources, it knows the interference situation between terminals in the SBFD time slot.

[0052] In an optional implementation manner of the embodiment of the present application, the manner of reporting the third measurement result and the fourth measurement result based on two reporting resources involved in the above step 22 may further include:

[0053] Step 51: report the third measurement result in one of the two reporting resources, and report the fourth measurement result in the other reporting resource of the two reporting resources except the reporting resource for reporting the third measurement result; wherein the correspondence between the two reporting resources and the third measurement result and the fourth measurement result is predefined by the network side device configuration or protocol.

[0054] In this regard, in a specific example, when there are two reporting resources in an embodiment of the present application, the network side device is configured or the protocol is predefined, and the terminal reports the measurement result on CSI-IM resource #1 on reporting resource #1 (PUCCH #1), and reports the measurement result on CSI-IM resource #2 on reporting resource #2 (PUCCH #2); or, the terminal reports the measurement result on CSI-IM resource #2 on reporting resource #1 (PUCCH #1), and reports the measurement result on CSI-IM resource #1 on reporting resource #2 (PUCCH #2).

[0055] In an optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

[0056] Step 103: Receive a time restriction (timeRestrictionForChannelMeasurements) configured by a network side device for indicating channel measurement, wherein the time restriction is used to indicate that channel measurement is performed on a measurement resource that is closest to the first time type or the second time type.

[0057] It can be seen that if the network side configures a time limit for channel measurement for the terminal, the terminal can obtain the measurement result according to the most recent reference signal of the first time type or the second time type respectively.

[0058] See also Figure 2 , Figure 2 is a flowchart of a CSI reporting method provided in an embodiment of the present application, which is used for a network side device, such as Figure 2 As shown, the method comprises the following steps:

[0059] Step 201, configure CSI reporting configuration, wherein the CSI reporting configuration includes at least one of the following configurations: one channel measurement resource, two CSI IM resources for interference measurement, and one or two reporting resources; the time domain position of the channel measurement resource includes at least one of the following types: a first time type and a second time type;

[0060] Step 202: Send a CSI reporting configuration to the terminal, and receive a CSI result reported by the terminal based on the CSI reporting configuration.

[0061] The above optional implementations can be found in Figure 1To avoid repeated description, the relevant descriptions in the illustrated embodiment will not be repeated in this embodiment.

[0062] It should be noted that the embodiments of the present application provide Figure 1 The CSI reporting method executed by the network side device corresponds to the CSI reporting method embodiment executed by the terminal shown, then all implementation methods in the CSI reporting method embodiment executed by the above terminal are applicable to the CSI reporting method executed by the network side device, and can achieve the same or similar beneficial effects.

[0065] The reporting module 304 is configured to perform CSI reporting based on the CSI reporting configuration.

[0066] It can be seen that in an embodiment of the present application, the terminal can receive a CSI reporting configuration configured by a network-side device, based on the CSI reporting configuration, wherein the CSI reporting configuration includes at least one of the following configurations: a channel measurement resource, two CSI IM resources for interference measurement, one or two reporting resources; the time domain position of the channel measurement resource includes at least one of the following types: a first time type, a second time type.
