Description

Channel state information report configuration method, device and computer readable storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for configuring a channel state information report, and a computer readable storage medium.

Background

Channel state information (Channel State Information, CSI) is important information that promotes the new energy of wireless communication systems. The terminal reports the CSI through the CSI report, and after receiving the CSI reported by the terminal, the access network equipment can schedule and allocate resources and manage beams according to the channel quality.

In the related art, an access network device configures CSI report configuration parameters for a terminal through a radio resource control (Radio Resource Control, RRC) message, and the terminal reports CSI according to the configured CSI report configuration parameters. If the access network device needs to change the CSI report configuration parameters, the CSI report configuration parameters of the terminal need to be changed through the RRC reconfiguration message, and more network resources are occupied due to the larger amount of information carried in the RRC reconfiguration message.

It should be noted that the foregoing steps 301-302 and the foregoing optional steps may be combined arbitrarily.

Fig. 4 is a flowchart illustrating a channel state information report configuration method according to an example embodiment. The method may be performed jointly by an access network device and a terminal. Referring to fig. 4, the method includes the steps of:

in step 401, the access network device generates configuration signaling.

The configuration signaling includes at least one set of channel state information resource configuration CSI resource config parameters and at least one set of channel state information reporting configuration CSI report config parameters. The number of groups allocated to the channel state information resource allocation of one terminal may be set according to actual needs. The number of sets of the channel state information report configuration parameters configured to one terminal may be set according to actual needs, without exceeding the upper limit value specified by the protocol. The upper limit value of the number of sets of the channel state information reporting configuration parameter may be 48, for example. Different sets of channel state report configuration parameters may correspond to different bandwidth portions and/or different measurement reference signals.

In the embodiment of the present disclosure, the at least one set of channel state information resource configuration CSI resource config parameters includes a first channel state information resource configuration parameter, where the first channel state information resource configuration parameter includes resource configurations corresponding to at least two reporting manners.

Optionally, the at least one set of channel state information resource configuration CSI resource config parameters may further include a second channel state information resource configuration parameter, where the second channel state information resource configuration parameter includes a resource configuration corresponding to a reporting mode.

Here, the report reporting manner may include periodic reporting, aperiodic reporting, and semi-persistent reporting.

In an embodiment of the present disclosure, the resource configuration corresponding to the reporting manner may include a channel state information Reference Signal (CSI-RS) resource set. The resource configurations corresponding to the periodic reporting and the semi-persistent reporting include a CSI-RS resource set. The aperiodic report corresponding resource configuration includes a plurality of CSI-RS resource sets.

Illustratively, the CSI-RS resources include at least one of Non-Zero-Power-CSI-RS (NZP-CSI-RS) resources, synchronization signal block (Synchronization Signal and PBCH, SSB) resources, and CSI-interference_measurement (CSI-IM) resources.

The first channel state information resource configuration parameter includes resource configurations corresponding to two reporting modes, wherein one of the two reporting modes is non-periodic reporting, and the other of the two reporting modes is periodic reporting or semi-continuous reporting.

In the embodiment of the present disclosure, the first channel state information resource configuration parameter is associated with at least one set of channel state information reporting configuration parameters, and the channel state information reporting configuration parameter associated with the first channel state information resource configuration parameter includes configuration parameters of the at least two reporting modes. The association means that when the access network device and the terminal adopt the report reporting mode in the associated channel state information report configuration parameters to report the CSI, the access network device needs to select resources to send the CSI-RS in the first channel state information resource configuration parameters, the terminal measures the CSI-RS on the corresponding resources, calculates the required CSI, and reports the required CSI to the access network device.

In one possible implementation, the at least two reporting manners are carried in a set of channel state information reporting configuration parameters. That is, at least one group of channel state information configuration parameters includes at least two information elements, and in the same group of channel state information configuration parameters, different information elements correspond to different reporting modes.

In one possible implementation, the at least one set of channel state information configuration parameters includes two information elements, one of which (hereinafter, referred to as a first information element) corresponds to an aperiodic report, and one of which (hereinafter, referred to as a second information element) corresponds to a periodic report or to a semi-persistent report. In this embodiment, the reporting manners corresponding to the two information elements are the same as the reporting manners corresponding to the associated first channel state information resource configuration parameters.

In another possible implementation manner, the at least one set of channel state information configuration parameters includes three information elements, and the three information elements correspond to three reporting modes of periodic reporting, non-periodic reporting and semi-continuous reporting respectively.

Illustratively, each information element includes at least a reporting mode, and when the reporting mode is periodic reporting and semi-continuous reporting, the information element may further include parameters such as reporting period; when the report reporting mode is aperiodic reporting, the information element may further include parameters such as a report triggering event.

In another possible implementation manner, the at least two reporting manners are respectively carried in a set of channel state information reporting configuration parameters. In this embodiment, each set of channel state information reporting configuration parameters includes an information element, where the information element includes at least a reporting mode, and when the reporting mode is periodic reporting and semi-persistent reporting, the information element may further include parameters such as a reporting period; when the report reporting mode is aperiodic reporting, the information element may further include parameters such as a report triggering event.

In a possible implementation manner, the configuration signaling further includes indication information, where the indication information is used to indicate a report reporting manner that is effective.

For example, when the set of channel state information configuration parameters includes at least two information elements, and each information element includes a different reporting mode, the indication information may be a switch identifier in each information element, and is used to indicate whether the reporting mode corresponding to the information element is effective. When the switch mark is a first value, the switch is turned on, namely, the corresponding report reporting mode is effective; and when the switch mark is a second value, closing the switch, namely, the corresponding report reporting mode is not effective. The switch identification may occupy 1 bit, the first value may be 1, and the second value may be 0; or vice versa, the first value may be 0 and the second value may be 1.

In this embodiment, the first information element corresponds to aperiodic report, and the corresponding switch identifier indicates a report reporting manner in which the aperiodic report is validated; the second information element corresponds to periodic reporting or semi-continuous reporting, and the corresponding switch identifier indicates that periodic reporting or semi-continuous reporting is not effective. Such as the case shown in table one.

In the embodiment of the present disclosure, the effective report reporting manner refers to a report reporting manner currently adopted by the terminal.

List one

CSI report config K	Non-periodic	Opening device
			CSI report config K	Periodic/semi-continuous	Switch for closing

In table one, CSI report config K is one of a plurality of sets of CSI reporting configuration parameters configured by the terminal.

In another possible implementation manner, the channel state information reporting configuration parameters associated with the first channel state information resource configuration parameters include configuration parameters of the at least two reporting modes, and the at least two reporting modes are respectively carried in a group of channel state information reporting configuration parameters. In this case, a switch identifier may be added to each set of channel state information reporting configuration parameters associated with the first channel state information resource configuration parameter, where the switch identifier is used to indicate whether the channel state information reporting configuration parameter corresponding to the information element to which the switch identifier belongs is effective, and since one set of channel state information reporting configuration parameters corresponds to one reporting mode, the switch identifier can indicate whether the corresponding reporting mode is effective. The manner of setting the switch flag may be referred to the foregoing manner, and a detailed description thereof will be omitted herein.

In step 402, the access network device sends the configuration signaling.

The configuration signaling may be higher layer signaling, such as RRC messages.

It should be noted that, the configuration signaling may be a change to an existing signaling (i.e. at least one information element corresponding to another reporting mode is added based on the original information element only including one reporting mode), or may be a new signaling, which is not limited in this disclosure.

In step 403, the terminal receives the configuration signaling.

In step 404, the terminal saves the channel state information resource configuration parameters and the channel state information report configuration parameters in the configuration signaling.

After receiving the configuration signaling, the terminal acquires the channel state information resource configuration parameters and the channel state information report configuration parameters from the configuration signaling, and stores the configuration parameters locally so as to measure according to the channel state information resource configuration parameters and report the CSI report according to the channel state information report configuration parameters.

In step 405, the terminal sends the CSI report according to the effective reporting mode.

Accordingly, the access network device receives the CSI report sent by the terminal.

The CSI includes at least one of channel Indication (Channel Quality Indicator, CQI) information, rank Indication (RI), and precoding matrix index (Precoding Matrix Indicator, PMI) information.

In step 405, if the report reporting mode in effect is aperiodic reporting, the terminal sends a CSI report according to the DCI indication after receiving the DCI sent by the access network device.

And if the effective report reporting mode is periodical reporting, the terminal sends the CSI report according to the parameters in the corresponding information elements.

If the effective reporting mode is semi-persistent reporting, the terminal needs to send the CSI report according to the parameters in the corresponding information elements after receiving the DCI for activation sent by the access network device.

Here, the aperiodic report transmits the CSI report using a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), and the periodic report transmits the CSI report using a physical uplink control channel (Physical Uplink Control Channel, PUCCH).

Optionally, if the access network device determines that the reporting mode of the terminal needs to be changed, the method may further include the following steps 406 to 408.

In step 406, the access network device sends first downlink control information.

The first downlink control information includes indication information for indicating that the terminal changes the effective report reporting mode from the first report reporting mode to the second report reporting mode. The indication information may be 1 bit, for example.

Here, the first reporting mode is a reporting mode that takes effect when the first downlink control information is received, and the second reporting mode is a reporting mode other than the first reporting mode among reporting modes that are preconfigured to the terminal.

In one possible embodiment, when the indication information is a first value (e.g., 0), the switching is indicated; when the instruction information is a second value (e.g., 1), it indicates that no switching is performed.

In another possible implementation manner, indexes may be allocated to the reporting manners corresponding to the first information element and the second information element, for example, the index of the reporting manner corresponding to the first information element is a first value (for example, 0), the index of the reporting manner corresponding to the second information element is a second value (for example, 1), and the access network device indicates to switch the reporting manners by setting the indication information to an index value different from the index value of the reporting manner currently in effect by the terminal (that is, to the index value of the second reporting manner).

In yet another possible implementation manner, a switch identifier (i.e., indication information) may be set for each of the first information element and the second information element, where when the switch identifier is 0, it indicates that the corresponding report reporting mode is not effective, and when the switch identifier is 1, it indicates that the corresponding report reporting mode is effective. The access network equipment can switch the report reporting mode by changing the switch identification.

For example, as shown in the following table two, for the K-th set of channel state information report configuration parameters, the switch identifier corresponding to the aperiodic report is 0, which indicates that the aperiodic report is not effective; the corresponding switch mark of the periodic/semi-continuous report is 1, which indicates that the periodic/semi-continuous report is effective; in table one, the opposite is true, so when the terminal receives the first downlink control information, it is necessary to perform the switching of reporting manners.

Watch II

CSI report config K	Non-periodic	Gateway (0)
			CSI report config K	Periodic/semi-continuous	Opening (1)

The above description has been made of the switching of the two reporting modes in the set of channel state information reporting configuration parameters, and the switching of the reporting modes is similar to the switching of the reporting modes in the two sets of channel state information reporting configuration parameters corresponding to different reporting modes, and a detailed description thereof will be omitted.

In one possible implementation manner, in response to determining that the number of non-periodic reports sent by the terminal and received by the access network device exceeds a first threshold within a predetermined duration, the access network device sends first downlink control information to instruct the terminal to change an effective reporting mode from a non-periodic reporting mode (i.e., a first reporting mode) to a reporting mode corresponding to a second information element (i.e., a second reporting mode).

In another possible implementation manner, in response to determining that the terminal supports reporting mode switching and that the number of non-periodic reports received from the terminal within a predetermined time period exceeds a first threshold, the first downlink control information is sent to the terminal, and the terminal is instructed to change the effective reporting mode from the non-periodic reporting mode (i.e., the first reporting mode) to the reporting mode corresponding to the second information element (i.e., the second reporting mode).

Here, the predetermined time period may be set according to actual needs, and the unit may be seconds. In this step 405, the access network device counts the number of aperiodic reports for each terminal, respectively.

Optionally, the method further comprises: the terminal sends the capability information; the access network equipment receives capability information sent by the terminal, wherein the capability information is used for indicating whether the terminal supports report reporting mode switching or not so that the access network equipment can know whether the terminal supports report reporting mode switching or not.

For example, the terminal may transmit the capability information in an RRC connection setup procedure. The capability information is sent, for example, by an RRC response message. Alternatively, the terminal may also send the capability information after receiving a capability query request sent by the access network device.

In step 407, the terminal receives the first downlink control information.

In step 408, the terminal changes the report reporting mode of the validation according to the first downlink control information.

For the terminal in the connected DRX, if the aperiodic report mode is adopted, after the access network equipment arrives at the UE, the UE needs to send the CSI report according to the uplink resource scheduled by the access network equipment, and under the condition that the number of the aperiodic reports is too large, the terminal cannot enter the sleep state, so that the power consumption of the terminal is too large. If periodic reporting or semi-continuous reporting is adopted, the terminal can enter a sleep state after sending the CSI report each time, and even if the reporting period is shorter, the power consumption of the terminal can be reduced compared with the situation that the terminal cannot enter the sleep state all the time by adopting an aperiodic reporting mode.

It should be noted that, as described above, a terminal may be configured with multiple sets of CSI report configuration parameters, and the access network device may select one or multiple sets from the multiple sets of CSI report configuration parameters to switch reporting manners, that is, send the first downlink control information for the selected CSI report configuration parameters. In an exemplary embodiment, in the selected CSI report configuration parameters, the aperiodic reporting mode is validated, and the aperiodic reporting probability is high, that is, the number of the aperiodic CSI reports can be triggered is high, so that the number of the aperiodic CSI reports sent by the terminal can be reduced.

Optionally, if the access network device determines that the reporting mode of the terminal needs to be changed again, the method may further include the following steps 409 to 412.

In step 407, the access network device sends the first downlink control information again.

The first downlink control information includes indication information for indicating that the terminal changes the effective report reporting mode from the first report reporting mode to the second report reporting mode. Similarly, the first reporting mode is a reporting mode that takes effect when the first downlink control information is received, and the second reporting mode is a reporting mode other than the first reporting mode among reporting modes that are preconfigured to the terminal. That is, the first reporting mode in the step 409 is the second reporting mode in the step 406, and the second reporting mode in the step 409 is the first reporting mode in the step 406.

In a possible implementation manner, the access network device may perform step 407 after a set period of time after performing step 406, that is, when the set period of time is reached after the last handover is performed, step 407 may be performed.

In another possible embodiment, the step 409 may include: and in response to determining that the number of the non-periodic reports sent by the terminal and received by the access network equipment does not exceed a second threshold value within a preset time length, the access network equipment sends the first downlink control information. That is, the access network device may switch back to reporting CSI by using the aperiodic report reporting mode when the number of the aperiodic reports received from the terminal is small, that is, when the power consumption of the terminal is less affected.

In another possible embodiment, the step 409 may include: and in response to determining that the terminal supports report reporting mode switching and determining that the number of the aperiodic reports sent by the terminal and received by the access network equipment does not exceed a second threshold, the access network equipment sends the first downlink control information.

Under the condition that the preset condition is met, the periodic reporting mode is switched back to the non-periodic reporting mode, so that the CSI reporting is more flexible, and resources are saved.

In step 410, the terminal receives first downlink control information.

In step 411, the terminal changes the report reporting mode that is in effect according to the first downlink control information.

In the embodiment of the present disclosure, the method is described by taking the case of switching from the aperiodic report reporting mode to the periodic or semi-persistent report reporting mode, and then switching from the periodic or semi-persistent report reporting mode, and in other embodiments, the method may also be performed by switching from the periodic or semi-persistent report reporting mode to the aperiodic report reporting mode, and then switching from the aperiodic report reporting mode to the periodic or semi-persistent report reporting mode. In addition, the embodiment of the disclosure is described by taking two switching as an example, and in practical application, there may be multiple reporting mode switching.

Optionally, if the report reporting mode in effect is semi-persistent reporting, the method may further include:

in step 412, the access network device sends second downlink control information.

The second downlink control information includes indication information for indicating the terminal to activate the semi-persistent reporting.

In step 413, the terminal receives the second downlink control information.

In step 414, the terminal sends the CSI report according to the parameters in the information element corresponding to the semi-persistent report.
