Description

CHANNEL STATE INFORMATION REPORT TRANSMISSION

BACKGROUND

A communication link between wireless nodes, such as between a user equipment (UE) and a base station (BS) , may be facilitated using channel state information (CSI) . For example, the BS (and/or one or more other BSs) may provide the UE with one or more signals requesting CSI, and the UE may provide one or more CSIs to the BS (and/or one or more other BSs) . One signal requesting CSI from the BS may be associated with one type, while another signal requesting CSI from the BS may be associated with another type. To maintain one or more communication links, the UE may need to calculate and/or generate CSI in accordance with the type associated with the corresponding signal. However, the UE may have limited resources and/or limited capabilities.

SUMMARY

In accordance with the present disclosure, one or more devices and/or methods for facilitating transmission of a channel state information (CSI) report are provided. In an example, a first signal comprising a request for a CSI report may be received from a wireless node. A second signal may be received from the wireless node. A setting may be determined for the CSI report based upon an indication of the setting in the second signal. A time slot for transmission of the CSI report may be determined based upon the setting. The CSI report may be transmitted to the wireless node at the time slot.

In an example, a signal comprising a request for a CSI report may be received from a wireless node. A setting may be determined for the CSI report based upon an application of a number of requests received for channel state information reports to one or more rules. A time slot for transmission of the CSI report may be determined based upon the setting. The CSI report may be transmitted to the wireless node at the time slot.

In an example, a setting may be determined based upon a number of requests, transmitted to a wireless node, for channel state information reports. A first signal comprising a request for a channel state information report may be generated. A second signal comprising an indication of the setting may be generated. The first signal and the second signal may be transmitted to the wireless node.

DETAILED DESCRIPTION

Subject matter will now be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific example embodiments. This description is not intended as an extensive or detailed discussion of known concepts. Details that are known generally to those of ordinary skill in the relevant art may have been omitted, or may be handled in summary fashion.

The following subject matter may be embodied in a variety of different forms, such as methods, devices, components, and/or systems. Accordingly, this subject matter is not intended to be construed as limited to any example embodiments set forth herein. Rather, example embodiments are provided merely to be illustrative. Such embodiments may, for example, take the form of hardware, software, firmware or any combination thereof.

One or more computing devices and/or techniques for facilitating transmission of a channel state information (CSI) report are provided. For example, a user equipment (UE) may connect to a (e.g.， wireless communication) network via a base station (BS) of the network. The BS may request one or more CSI reports from the UE. The one or more CSI reports may be used, for example, to enable the BS to communicate with the UE reliably and/or with high data rates (e.g.， by enhancing signals sent from the BS to the UE based upon information in the CSI reports, etc. ) . A connection between the UE and BS may involve the transmittal of a (e.g.， large) number of requests from the BS to the UE and/or a large (e.g.， large) number of CSI reports from the UE to the BS. A number, frequency and/or variety (e.g., of types) of CSI reports generated by the UE may depend upon a capability of the UE. Some methods of facilitating transmission of CSI reports may result in interference between transmitted requests, transmitted CSI reports and/or other transmitted data, and/or may transmit fewer CSI reports than made possible by a capability of the UE (e.g.， and thus provide for communication between the BS and the UE that is less reliable and/or associate with a lower data rate than is possible) . Thus, in accordance with one or more of the techniques presented herein, the transmission of CSI reports may be facilitated in a manner that balances the risk of interference and the capability of the UE to provide for optimal communication between the BS (e.g., and/or one or more other BSs) and the UE (e.g.， and/or one or more other UEs) .

An example method 100 of facilitating the transmission of a CSI report from a first wireless node to a second wireless node is illustrated in Fig. 1. The first wireless node may be a UE and the second wireless node may be a network and/or BS. The first wireless node may (e.g.， be required to) send one or more CSI reports to the second wireless node in order to maintain a connection (e.g.， between the first wireless node and the second wireless node) . Accordingly, at 105, the first wireless node receives a first signal comprising a request for a CSI report (e.g.， from the second wireless node) .

In some examples, the request may correspond to a semi-persistent CSI configuration. For example, the request corresponding to the semi-persistent CSI configuration may comprise an activation instruction for a periodic transmission of one or more CSI reports (e.g.， to the second wireless node) . Once activated based upon the activation instruction, the first wireless node may transmit (e.g.， to the second wireless node) an initial CSI report at a time slot, and periodically transmit (e.g.， to the second wireless node) one or more CSI reports based upon the activation instruction after transmission of the initial CSI report (e.g.， where the initial CSI report and/or the one or more CSI reports may be generated and/or transmitted in response to the (same) activation instruction) . The first wireless node may then receive a deactivation instruction. Once deactivated based upon the deactivation instruction, the first wireless node may terminate (e.g.， cease) the periodic transmission of CSI reports (e.g.， to the second wireless node) based upon the activation instruction. It may be appreciated that after terminating the periodic transmission of CSI reports based upon the activation instruction, the first wireless node may continue and/or initiate a periodic transmission of CSI reports based upon one or more other activation instructions.

In some examples, the request may correspond to an aperiodic CSI configuration. For example, the request corresponding to the aperiodic CSI configuration may comprise a trigger for a single transmission of a CSI report (e.g., to the second wireless node) . Upon receiving the trigger for the single transmission, the first wireless node may transmit (e.g.， merely) the CSI report and may transmit zero more (e.g.， other) CSI reports based upon the trigger for the single transmission after transmitting the CSI report.

In some examples, the first wireless node may determine a time slot at which to transmit a CSI report. The first wireless node may determine the time slot based upon a first setting and/or a second setting. For example, the second setting may comprise a basic value (e.g.， T1) corresponding to a latency associated with transmission of the CSI report and/or the first setting may comprise an offset value (e.g.， T2) corresponding to an offset of the latency associated with transmission of the CSI report.

At 110, the first wireless node may receive a second signal from the second wireless node. In some examples, the second wireless node may generate the second signal to explicitly indicate the first setting to the first wireless node. Thus at 115, the first wireless node may determine the first setting based upon an indication of the first setting in the second signal. In some examples, the second signal may be a Media Access Control (MAC) -layer signal or a Physical (PHY) -layer signal.

A number of triggered but not transmitted CSI reports may be determined based upon a difference between a number of triggers received (e.g., by the first wireless node and/or from the second wireless node) and a number of CSI reports transmitted (e.g.， by the first wireless node and/or to the second wireless node) . In response to determining that the difference exceeds a threshold, the first setting may be determined as a first value. In response to determining that the difference does not exceed the threshold, the first setting may be determined as a second value. In some examples, the first value is greater than or equal to 0, the second value is less than or equal to 0 and/or the threshold is greater than or equal to 0.

The first wireless node may receive a third signal explicitly indicating the second setting. Accordingly, the first wireless node may determine (e.g.， identify) the second setting based upon the indication of the second setting in the third signal. In some examples, the third signal may not explicitly indicate the second setting, and the first wireless node may determine the second setting based upon a type of CSI report (e.g., low-resolution beam based codebook, high-resolution linear combination codebook, etc. ) determined based upon the third signal . For example, in an instance where a first type of CSI report is determined based upon the third signal, a first value may be determined for the second setting, while in an instance where a second type of CSI report is determined based upon the third signal, a second value may be determined for the second setting. In some examples, rather than using the third signal to determine the second setting, the first wireless node may determine the second setting based upon the type of the CSI report determined from the request.

At 120, the first wireless node may determine the time slot for transmission of the CSI report based upon the first setting. The first wireless node may (e.g.， also) use the second setting to determine the time slot. The time slot may be determined by a (e.g.， mathematical) combination of the first setting and the second setting, such as the sum of the first setting and the second setting.

At 125, the first wireless node may transmit, at the time slot, the CSI report to the second wireless node.

In some examples, one or more other CSI report transmissions may conflict with the transmission of the CSI report at the time slot. For example, the one or more other CSI report transmissions may have the (same) time slot determined for the transmission of the CSI report. Here, the CSI report may be transmitted prior to transmitting the one or more other CSI report transmissions based upon a determination that the CSI report corresponds to an earlier request than the one or more CSI report transmissions (e.g., a queue model) . Alternatively, the CSI report may be transmitted after transmitting the one or more other CSI report transmissions based upon a determination that the CSI report corresponds to an earlier request than the one or more CSI report transmissions (e.g.， a stack model) .

The one or more other CSI reports may be transmitted in increasing order, according to their corresponding request times (e.g.， the queue model) . For example, in response to determining that the request for the CSI report transmission was received prior to receiving a second request for a second CSI report and the second request was received prior to receiving a third request for a third CSI report, the first CSI report may be transmitted before the second CSI report is transmitted, and/or the second CSI report may be transmitted before the third CSI report is transmitted. It may be appreciated that one or more CSI report transmissions, in addition to those corresponding to the second request, the third request, etc., may conflict with the transmission of the CSI report at the time slot, and may be processed in a similar manner.

Alternatively and/or additionally, the one or more other CSI reports may be transmitted in decreasing order, according to their corresponding request times (e.g.， the stack model) . For example, in response to determining that the request for the CSI report transmission was received prior to receiving the second request for the second CSI report and the second request was received prior to receiving the third request for the third CSI report, the third CSI report may be transmitted before the second CSI report is transmitted, and/or the second CSI report may be transmitted before the first CSI report is transmitted. It may be appreciated that one or more CSI report transmissions, in addition to those corresponding to the second request, the third request, etc., may conflict with the transmission of the CSI report at the time slot, and may be processed in a similar manner.

In some examples, such as examples involving a time division duplex (TDD) configuration, an uplink resource may be (e.g.， required to be) available (e.g.， to the first wireless node) for the CSI report to be able to be transmitted to the second wireless node. In response to determining that the time slot does not have an uplink resource available, the first wireless node may identify a replacement time slot for which an uplink resource is available and/or may attempt to transmit the CSI report to the second wireless node at the replacement time slot. In some examples, the replacement time slot is a first available time slot for which an uplink resource is available, after the time slot. If a determination is made that the difference between the replacement time slot and the time slot in which the request for the CSI report was received at the first wireless node exceeds a latency threshold, the first wireless node may terminate transmission of the CSI report. The latency threshold may be greater than or equal to 0.

In some examples involving a semi-persistent configuration, the first wireless node may hold (e.g.， pause, freeze, etc. ) transmission of CSI reports if a determination is made that a difference between a number of activation instructions received (e.g.， by the first wireless node) and a number of deactivation instructions received (e.g.， by the first wireless node) exceeds a threshold. The first wireless node may hold transmission of CSI reports during the time that the difference exceeds the threshold and/or may resume or start transmission of one or more CSI reports when a determination is made that the difference no longer exceeds the threshold. The threshold may depend upon a capability of the first wireless node.

In some examples involving an aperiodic configuration, the first wireless node may hold (e.g.， pause, freeze, etc. ) transmission of CSI reports if a determination is made that a difference between a number of triggers received (e.g.， by the first wireless node) and a number of transmitted CSI reports (e.g.， from the first wireless node and/or to the second wireless node) exceeds a threshold. The first wireless node may hold transmission of CSI reports during the time that the difference exceeds the threshold and/or may resume or start transmission of one or more CSI reports when a determination is made that the difference no longer exceeds the threshold. The threshold may depend on the capability of the first wireless node.

An example method 200 of facilitating the transmission of a CSI report from a first wireless node to a second wireless node is illustrated in Fig. 2. The first wireless node may be a UE and the second wireless node may be a network and/or BS. The first wireless node may (e.g.， be required to) send one or more CSI reports to the second wireless node in order to maintain a connection (e.g.， between the first wireless node and the second wireless node) . Accordingly, at 205, the first wireless node receives a first signal comprising a request for a CSI report (e.g.， from the second wireless node) .

In some examples, the request may correspond to a semi-persistent CSI configuration. In some examples, the request may correspond to an aperiodic CSI configuration.

At 210, the first wireless node may determine the first setting based upon an application of a number of requests received for CSI reports to one or more (e.g.， predefined) rules (e.g.， stored in the first wireless node) .

In some examples where the request corresponds to a semi-persistent CSI configuration, the first setting may be determined by applying a number of activated CSI reports (e.g.， corresponding to a number of simultaneous CSI calculations, being performed by the first wireless node, greater than or equal to 0) to the one or more (e.g.， pre-defined) rules.

In some examples, the one or more rules that are used may correspond to a type of CSI report requested (e.g.， which may be determined based upon the request and/or another signal) . For example, in an instance where a CSI report of a first type (e.g.， low-resolution beam based codebook) is requested, the corresponding number of activated CSI reports may be applied to one or more first rules to determine the first setting, while in another instance where a CSI report of a second type (e.g.， high-resolution linear combination codebook) is requested, the corresponding number of activated CSI reports may be applied to one or more second rules to determine the first setting.

In some examples, the one or more rules that are used may correspond to a mode of the semi-persistent CSI configuration associated with the CSI report requested. For example, in an instance where a CSI report associated with a first mode (e.g.， a frequency division duplex (FDD) mode) is requested, the corresponding number of activated CSI reports may be applied to one or more first rules to determine the first setting, while in another instance where a CSI report associated with a second mode (e.g., a TDD mode) is requested, the corresponding number of activated CSI reports may be applied to one or more second rules to determine the first setting.

The number of activated CSI reports may be determined based upon a difference between a number of activation instructions received (e.g., by the first wireless node and/or from the second wireless node) and a number of deactivation instructions received (e.g.， by the first wireless node and/or from the second wireless node) . In response to determining that the difference exceeds a threshold, the first setting may be determined as a first value. In response to determining that the difference does not exceed the threshold, the first setting may be determined as a second value. In some examples, the first value is greater than or equal to 0, the second value is less than or equal to 0 and the threshold is greater than or equal to 0.

In some examples where the request corresponds to an aperiodic CSI configuration, the first setting may be determined by applying a number of triggered but not transmitted CSI reports (e.g.， corresponding to a number of simultaneous CSI calculations, being performed by the first wireless node, greater than or equal to 0) to one or more (e.g.， pre-defined) rules.

In some examples, the one or more rules that are used may correspond to a type of CSI report requested (e.g.， which may be determined based upon the request and/or another signal) . For example, in an instance where a CSI report of a first type (e.g.， low-resolution beam based codebook) is requested, the corresponding number of triggered but not transmitted CSI reports may be applied to one or more first rules to determine the first setting, while in another instance where a CSI report of a second type (e.g., high-resolution linear combination codebook) is requested, the corresponding number of triggered but not transmitted CSI reports may be applied to one or more second rules to determine the first setting.

In some examples, the one or more rules that are used may correspond to a mode of the aperiodic CSI configuration associated with the CSI report requested. For example, in an instance where a CSI report associated with a first mode (e.g.， an FDD mode) is requested, the corresponding number of triggered but not transmitted CSI reports may be applied to one or more first rules to determine the first setting, while in another instance where a CSI report associated with a second mode (e.g., a TDD mode) is requested, the corresponding number of triggered but not transmitted CSI reports may be applied to one or more second rules to determine the first setting.

The number of triggered but not transmitted CSI reports may be determined based upon a difference between a number of triggers received (e.g., by the first wireless node and/or from the second wireless node) and a number of CSI reports transmitted (e.g.， by the first wireless node and/or to the second wireless node) . In response to determining that the difference exceeds a threshold, the first setting may be determined as a first value. In response to determining that the difference does not exceed the threshold, the first setting may be determined as a second value. In some examples, the first value is greater than or equal to 0, the second value is less than or equal to 0 and/or the threshold is greater than or equal to 0.

The first wireless node may receive a second signal explicitly indicating the second setting. Accordingly, the first wireless node may determine (e.g.， identify) the second setting based upon the indication of the second setting in the second signal. In some examples, the second signal may not explicitly indicate the second setting, and the second wireless node may determine the second setting based upon a type of CSI report (e.g., low-resolution beam based codebook, high-resolution linear combination codebook, etc. ) determined based upon the second signal . For example, in an instance where a first type of CSI report is determined based upon the second signal, a first value may be determined for the second setting, while in an instance where a second type of CSI report is determined based upon the second signal, a second value may be determined for the second setting. In some examples, rather than using the second signal to determine the second setting, the second wireless node may determine the second setting based upon the type of the CSI report determined from the request.

At 215, the first wireless node may determine the time slot for transmission of the CSI report based upon the first setting. The first wireless node may (e.g.， also) use the second setting to determine the time slot. The time slot may be determined by a (e.g.， mathematical) combination of the first setting and the second setting, such as the sum of the first setting and the second setting.

At 220, the first wireless node may transmit, at the time slot, the CSI report to the second wireless node.

In some examples, such as examples involving a TDD configuration, an uplink resource may be (e.g.， required to be) available (e.g.， to the first wireless node) for the CSI report to be able to be transmitted to the second wireless node. In response to determining that the time slot does not have an uplink resource available, the first wireless node may identify a replacement time slot for which an uplink resource is available and/or may attempt to transmit the CSI report to the second wireless node at the replacement time slot. In some examples, the replacement time slot is a first available time slot for which an uplink resource is available, after the time slot. If a determination is made that the difference between the replacement time slot and the time slot in which the request for the CSI report was received at the first wireless node exceeds a latency threshold, the first wireless node may terminate transmission of the CSI report. The latency threshold may be greater than or equal to 0.

An example method 300 of facilitating the transmission of a CSI report from a first wireless node to a second wireless node is illustrated in Fig. 3. The first wireless node may be a network and/or BS and the second wireless node may be a UE. The first wireless node may request one or more CSI reports from the second wireless node. The second wireless node may (e.g., be required to) send one or more CSI reports to the first wireless node in order to maintain a connection (e.g.， between the first wireless node and the second wireless node) .

At 305, the first wireless node may determine a first setting based upon a number of requests for CSI reports transmitted to the second wireless node (e.g.， from the first wireless node) . The first setting may be used by the first wireless node to generate a request for a CSI report.

In some examples where the request corresponds to a semi-persistent CSI configuration, the number of requests for CSI reports corresponds to a number of activated CSI reports (e.g.， corresponding to a number of simultaneous CSI calculations, being performed by the first wireless node, greater than or equal to 0) .

The number of activated CSI reports may be determined based upon a difference between a number of activation instructions transmitted (e.g., by the first wireless node and/or to the second wireless node) and a number of deactivation instructions transmitted (e.g.， by the first wireless node and/or to the second wireless node) . In response to determining that the difference exceeds a threshold, the first setting may be determined as a first value. In response to determining that the difference does not exceed the threshold, the first setting may be determined as a second value. In some examples, the first value is greater than or equal to 0, the second value is less than or equal to 0 and the threshold is greater than or equal to 0.

In some examples where the request corresponds to an aperiodic CSI configuration, the number of requests for CSI reports corresponds to a number of triggered but not transmitted CSI reports (e.g.， corresponding to a number of simultaneous CSI calculations, being performed by the first wireless node, greater than or equal to 0) to one or more (e.g.， pre-defined) rules.

The number of triggered but not transmitted CSI reports may be determined based upon a difference between a number of triggers transmitted (e.g., by the first wireless node and/or to the second wireless node) and a number of CSI reports received (e.g.， by the first wireless node and/or from the second wireless node) . In response to determining that the difference exceeds a threshold, the first setting may be determined as a first value. In response to determining that the difference does not exceed the threshold, the first setting may be determined as a second value. In some examples, the first value is greater than or equal to 0, the second value is less than or equal to 0 and/or the threshold is greater than or equal to 0.

At 310, the first wireless node may generate a first signal comprising the request for the CSI report.

At 315, the first wireless node may generate a second signal comprising an indication of the first setting.

At 320, the first wireless node may transmit the first signal and the second signal to the second wireless node.

In some examples, the first wireless node may also transmit a third signal. In some examples, the third signal may explicitly indicate the second setting. Accordingly, the second wireless node may determine (e.g.， identify) the second setting based upon the indication of the second setting in the third signal. In some examples, the third signal may not explicitly indicate the second setting, and may instead identify and/or be associated with a type of CSI report (e.g.， low-resolution beam based codebook, high-resolution linear combination codebook, etc. ) . The type of the CSI report may then be used by the second wireless node to determine the second setting. For example, in an instance where the third signal is associated with a first type of CSI report, a first value may be determined for the second setting by the second wireless node, while in an instance where the third signal is associated with a second type of CSI report, a second value may be determined for the second setting by the second wireless node. In some examples, the request may be associated with the type of the CSI report, and rather than using the third signal to determine the second setting, the second wireless node may determine the second setting based upon the type of the CSI report determined from the request.

In some examples, the first wireless node may receive, at a time slot, the CSI report from the second wireless node. The first wireless node and/or the second wireless node may determine the time slot for transmission of the CSI report based upon the first setting. The first wireless node and/or the second wireless node may (e.g.， also) use the second setting to determine the time slot. The time slot may be determined by a (e.g.， mathematical) combination of the first setting and the second setting, such as the sum of the first setting and the second setting.

Fig. 4 illustrates an example of a system 400 for facilitating transmission of a CSI report 420 from a first wireless node 410 (e.g.， a UE) to a second wireless node 405 (e.g.， a network) . The first wireless node 410 may receive a first signal 415 comprising a request for a CSI report from the second wireless node 405. Upon receiving the request, the first wireless node 410 may transmit the CSI report 420 to the second wireless node 405 (e.g., in response to the request) .

Fig. 5 illustrates an example of a system 500 for facilitating transmission of one or more CSI reports from the first wireless node 410 to the second wireless node 405 in a semi-persistent CSI configuration. For example, the second wireless node 405 may transmit, to the first wireless node 410, an activation instruction 505 (e.g.， in a first signal) for a periodic transmission of one or more CSI reports (e.g.， to the second wireless node 405) . Once activated based upon the activation instruction 505, the first wireless node 410 may transmit (e.g.， to the second wireless node 405) an initial CSI report 510, and may periodically transmit (e.g.， to the second wireless node 405) one or more CSI reports based upon the (e.g., same) activation instruction 505 after transmission of the initial CSI report 510. For example, after transmission of the initial CSI report 510, the first wireless node 410 may transmit a second CSI report 515 and/or one or more other CSI reports, such as a third CSI report 520 (e.g.， to the second wireless node 405) . The second wireless node 405 may then transmit a deactivation instruction 525 (e.g.， to the first wireless node 410) . Once deactivated based upon the deactivation instruction 525, the first wireless node 410 may terminate (e.g., cease) the periodic transmission of one or more CSI reports (e.g., to the second wireless node 405) based upon the activation instruction 505.

Fig. 6 illustrates an example of a system 600 for facilitating transmission of one or more CSI reports from the first wireless node 410 to the second wireless node 405 in a semi-persistent CSI configuration. For example, the second wireless node 405 may transmit, to the first wireless node 410, a first activation instruction 605 (e.g.， in a first signal) for a periodic transmission of one or more CSI reports (e.g.， to the second wireless node 405) . Once activated based upon the first activation instruction 605, the first wireless node 410 may transmit (e.g.， to the second wireless node 405) a first initial CSI report 610, and may periodically transmit (e.g.， to the second wireless node 405) one or more CSI reports based upon the (e.g.， same) first activation instruction 605 after transmission of the first initial CSI report 610. For example, after transmission of the first initial CSI report 610, the first wireless node 410 may transmit a second CSI report 620 (e.g.， to the second wireless node 405) . The second wireless node 405 may then transmit a first deactivation instruction 630 (e.g.， to the first wireless node 410) . Once deactivated based upon the first deactivation instruction 630, the first wireless node 410 may terminate (e.g.， cease) the periodic transmission of one or more CSI reports (e.g.， to the second wireless node 405) based upon the first activation instruction 605.

After the first wireless node 410 transmits the first initial CSI report 610 (e.g.， to the second wireless node 405) and/or before the first wireless node 410 transmits the second CSI report 620, the second wireless node 405 may transmit a second activation instruction 615 (e.g.， in a second signal) for a periodic transmission of one or more CSI reports (e.g.， to the second wireless node 405) . After the first wireless node 410 transmits the second CSI report 620 (e.g.， to the second wireless node 405) and/or before the second wireless node 405 transmits the first deactivation instruction 630, the first wireless node may transmit a second initial CSI report 625 (e.g., to the second wireless node 405) based upon the second activation instruction 615.

After the second wireless node 405 transmits the deactivation instruction 630 (e.g.， to the first wireless node 410) , the first wireless node 410 may transmit a second CSI report 635 (e.g.， to the second wireless node 405) based upon the second activation instruction 615. The first wireless node 410 may then transmit a third CSI report 640 (e.g.， to the second wireless node 405) based upon the second activation instruction 615. The second wireless node 405 may then transmit a second deactivation instruction 645 (e.g., to the first wireless node 410) . Once deactivated based upon the second deactivation instruction 645, the first wireless node 410 may terminate (e.g., cease) the periodic transmission of one or more CSI reports (e.g., to the second wireless node 405) based upon the second activation instruction 615.

Fig. 7 illustrates an example of a system 700 for facilitating transmission of one or more CSI reports from the first wireless node 410 to the second wireless node 405 in an aperiodic CSI configuration. For example, the second wireless node 405 may transmit (e.g.， to the first wireless node 410) a first signal 705 comprising a first trigger for a single transmission of a CSI report (e.g.， to the second wireless node 405) . Upon receiving the first trigger for the single transmission, the first wireless node 410 may transmit a first CSI report 710 to the second wireless node 405 (e.g.， in response to the first trigger) . The first wireless node 410 may not transmit, in response to the (same) first trigger, one or more other CSI reports to the second wireless node 405 after transmitting the first CSI report 710. The second wireless node 405 may then transmit (e.g.， to the first wireless node 410) a second signal 715 comprising a second trigger for a single transmission of a CSI report (e.g., to the second wireless node 405) . Upon receiving the second trigger for the single transmission, the first wireless node 410 may transmit a second CSI report 720 to the second wireless node 405 (e.g.， in response to the second trigger) . The first wireless node 410 may not transmit, in response to the (same) second trigger, one or more other CSI reports to the second wireless node 405 after transmitting the second CSI report 720.

Fig. 8 illustrates an example of a system 800 for facilitating transmission of one or more CSI reports from the first wireless node 410 to the second wireless node 405 in an aperiodic CSI configuration. For example, the second wireless node 405 may transmit (e.g.， to the first wireless node 410) a first signal 805 comprising a first trigger for a single transmission of a CSI report (e.g.， to the second wireless node 405) . The second wireless node 405 may then transmit (e.g.， to the first wireless node 410) a second signal 810 comprising a second trigger for a single transmission of a CSI report (e.g., to the second wireless node 405) . In response to the first trigger for the single transmission, the first wireless node 410 may transmit a first CSI report 815 (e.g., to the second wireless node 405) after the second signal 810 is received (e.g., by the first wireless node 410) . The first wireless node 410 may not transmit, in response to the (same) first trigger, one or more other CSI reports to the second wireless node 405 after transmitting the first CSI report 815. In response to the second trigger for the single transmission, the first wireless node 410 may transmit a second CSI report 820 (e.g.， to the second wireless node 405) after the first CSI report 815 is transmitted (e.g.， to the second wireless node 405) . The first wireless node 410 may not transmit, in response to the (same) second trigger, one or more other CSI reports to the second wireless node 405 after transmitting the second CSI report 820.

Fig. 9 illustrates an example of a system 900 for facilitating transmission of one or more CSI reports from the first wireless node 410 to the second wireless node 405 in an aperiodic CSI configuration. For example, the second wireless node 405 may transmit (e.g.， to the first wireless node 410) a first signal comprising a trigger for a single transmission of a first CSI report 905 (e.g.， to the second wireless node 405) . In response to the trigger for the single transmission, the first CSI report 905 corresponding to the trigger may be stored (e.g.， calculated, processed) inside a processor of the first wireless node 410 (e.g.， a UE processor) until it is transmitted (e.g., reported) (e.g.， to the second wireless node 405) .

The second wireless node 405 (e.g.， and/or one or more other wireless nodes) may then transmit (e.g.， to the first wireless node 410) one or more other signals comprising one or more triggers for one or more single transmissions of one or more CSI reports (e.g.， to the second wireless node 405) . In response to the one or more triggers for the one or more single transmissions, the one or more other CSI reports corresponding to the one or more triggers may be stored (e.g.， calculated, processed) inside the processor until they are transmitted (e.g.， to the second wireless node 405) . For example, the second wireless node 405 may transmit (e.g.， to the first wireless node 410) a second signal comprising a second trigger for a single transmission of a second CSI report 910 (e.g.， to the second wireless node 405) . In response to the second trigger for the single transmission, the second CSI report 910 corresponding to the second trigger may be stored (e.g.， calculated, processed) in the processor until it is transmitted (e.g.， to the second wireless node 405) .

The second wireless node 405 may then transmit (e.g.， to the first wireless node 410) a third signal comprising a third trigger for a single transmission of a third CSI report 915 (e.g.， to the second wireless node 405) . In response to the third trigger for the single transmission, the third CSI report 915 corresponding to the third trigger may be stored (e.g.， calculated, processed) in the processor until it is transmitted (e.g.， to the second wireless node 405) . Hence, during the time that the first CSI report 905, the second CSI report 910 and/or the third CSI report 915 are stored (e.g.， calculated, processed) in the processor, the number of triggered but not transmitted CSI reports may be equal to (e.g.， at least) 3.

Fig. 10A illustrates an example of a scenario 1000 corresponding to a system for facilitating transmission of one or more CSI reports from the first wireless node 410 (not illustrated in Fig. 10A) to the second wireless node 405 (not illustrated in Fig. 10A) . At the first time slot S0, the first wireless node 410 may receive (e.g.， from the second wireless node 405) a first signal 1005 comprising a request for a CSI report 1015A. The second setting (e.g., T1) of the CSI report 1015A corresponding to the request may be determined to be 5 time slots. The second setting (e.g.， T1) may be determined by high-layer signaling (e.g.， RRC layer) associated with the first signal 1005. Hence, a time slot that may be determined for the CSI report 1015A to be transmitted (e.g., to the second wireless node 405) may be slot S5 or a time slot after slot S5. At the second time slot S1, the first wireless node 410 may receive (e.g., from the second wireless node 405 and/or one or more other wireless nodes) a second signal 1010 comprising a second request for a second CSI report. The second CSI report may not be transmitted until after the seventh time slot S6. At the sixth time slot S5, a number of triggered but not transmitted CSI reports (e.g.， 4) may exceed a threshold (e.g.， 3) , and in response to the number of triggered but not transmitted CSI reports exceeding the threshold, the first setting (e.g.， T2) for the CSI report 1015A may be determined as a first value (e.g.， 1) . Thus, the CSI report 1015A may be transmitted (e.g., to the second wireless node 405) at a number of time slots (e.g.， T1+T2) after the time slot (e.g.， time slot S0) at which the first signal 1005 was received by the first wireless node 410. The number of time slots may be equal to a (e.g., mathematical) combination of the first setting (e.g.， 1) and the second setting (e.g., 5) . For example, the number of time slots may be equal to the sum of the first setting (e.g.， 1) and the second setting (e.g.， 5) . Thus, the CSI report 1015A may be transmitted at 6 time slots after time slot S0 (e.g.， time slot S6) . It may be appreciated that the threshold may be based upon a capability of the first wireless node 410.

Fig. 10B illustrates an example of a scenario 1050 corresponding to a system for facilitating transmission of one or more CSI reports from the first wireless node 410 (not illustrated in Fig. 10B) to the second wireless node 405 (not illustrated in Fig. 10B) . At the first time slot S0, the first wireless node 410 may receive (e.g.， from the second wireless node 405) the first signal 1005 comprising a request for a CSI report 1015B. The second setting (e.g., T1) of the CSI report 1015B corresponding to the request may be determined to be 5 time slots. The second setting (e.g.， T1) may be determined by high-layer signaling (e.g.， RRC layer) associated with the first signal 1005. Hence, a time slot that may be determined for the CSI report 1015B to be transmitted (e.g., to the second wireless node 405) may be slot S5 or a time slot after slot S5. At the second time slot S1, the first wireless node 410 may receive (e.g., from the second wireless node 405 and/or one or more other wireless nodes) the second signal 1010 comprising the second request for the second CSI report. The second CSI report may not be transmitted until after the seventh time slot S6. At the sixth time slot S5, the number of triggered but not transmitted CSI reports (e.g.， 2) may not exceed the threshold (e.g.， 3) , and in response to the number of triggered but not transmitted CSI reports not exceeding the threshold, the first setting (e.g.， T2) for the CSI report 1015B may be determined as a second value (e.g.， 0) and/or may not be determined. Thus, the CSI report 1015B may be transmitted (e.g.， to the second wireless node 405) at a second number of time slots (e.g.， T1) after the time slot (e.g., time slot S0) at which the first signal 1005 was received by the first wireless node 410. The second number of time slots may be equal to the second setting (e.g.， 5) . Thus, the CSI report 1015B may be transmitted at 5 time slots after time slot S0 (e.g.， time slot S5) . It may be appreciated that the threshold may be based upon a capability of the first wireless node 410.

Fig. 11 illustrates an example of a scenario 1100 corresponding to a system for facilitating transmission of one or more CSI reports from the first wireless node 410 (not illustrated in Fig. 11) to the second wireless node 405 (not illustrated in Fig. 11) in a configuration (e.g.， TDD configuration) where an uplink resource may be required to be available for a CSI report to be transmitted (e.g.， to the second wireless node 405) . At time slot S0, the first wireless node 410 may receive (e.g.， from the second wireless node 405) a first signal 1105 comprising a request for a CSI report 1110. The combination (e.g., sum) of the first setting (e.g.， T2) and the second setting (e.g.， T1) of the CSI report 1110 (e.g.， T1+T2) corresponding to the request may be determined to be 3 time slots. Hence, a time slot that may be determined for the CSI report 1110 to be transmitted (e.g.， to the second wireless node 405) may be time slot S3.

At time slot S3, there may not be an uplink resource available for the CSI report 1110 to be transmitted (e.g.， to the second wireless node 405) . The first wireless node 410 may identify a replacement time slot for which an uplink resource is available. The replacement time slot may be a first available time slot for which an uplink resource is available, after the time slot (e.g., S3) determined for the CSI report 1110 to be transmitted. For example, the replacement time slot determined (e.g.， identified) to be the first available time slot for which an uplink resource is available may be time slot SN, which may be a number N time slots after the time slot (e.g.， S3) determined for the CSI report 1110 to be transmitted. Thus, the CSI report 1110 may be transmitted at time slot SN, N time slots after the time slot (e.g., S3) determined for the CSI report 1110 to be transmitted (e.g.， T1+T2+N) .

Fig. 12 illustrates an example of a scenario 1200 corresponding to a system for facilitating transmission of one or more CSI reports from the first wireless node 410 (not illustrated in Fig. 12) to the second wireless node 405 (not illustrated in Fig. 12) in a configuration (e.g.， TDD configuration) where an uplink resource may be required to be available for a CSI report to be transmitted (e.g.， to the second wireless node 405) . At time slot S0, the first wireless node 410 may receive (e.g.， from the second wireless node 405) a first signal 1205 comprising a request for a CSI report 1215. At time slot S1, the first wireless node 410 may receive (e.g.， from the second wireless node 405) a second signal 1210 comprising a second request for a second CSI report 1220. The combination (e.g.， sum) of the first setting (e.g.， T2) and the second setting (e.g.， T1) of the CSI report 1215 (e.g.， T1+T2) corresponding to the request may be determined to be 3 time slots. Hence, a time slot that the CSI report 1215 may be transmitted (e.g.， to the second wireless node 405) may be time slot S3.

At time slot S3, there may not be an uplink resource available for the CSI report 1215 to be transmitted (e.g.， to the second wireless node 405) . The first wireless node 410 may identify a replacement time slot for which an uplink resource is available. The replacement time slot may be a first available time slot for which an uplink resource is available, after the time slot (e.g., S3) determined for the CSI report 1215 to be transmitted. For example, the replacement time slot determined (e.g.， identified) to be the first available time slot for which an uplink resource is available may be time slot S6, 3 time slots after the time slot (e.g.， S3) determined for the CSI report 1215 to be transmitted (e.g.， T1+T2+3) . The first wireless node 410 may terminate the CSI report 1215 if a difference between the replacement time slot (e.g., S6) and time slot S0 in which the request for the CSI report was received at the first wireless node 410 exceeds a latency threshold (e.g.， 6) . In response to determining that the difference (e.g.， 6) does not exceed the latency threshold (e.g., 6) the first wireless node 410 may transmit (e.g.， and not terminate) the CSI report 1215 (e.g.， to the second wireless node 405) .

The sum of the first setting (e.g.， T2) and the second setting (e.g., T1) of the second CSI report 1220 (e.g.， T1+T2) corresponding to the second request may be determined to be 3 time slots. Hence, a second time slot that the CSI report 1220 may be transmitted (e.g.， to the second wireless node 405) may be time slot S4. At time slot S4, there may not be an uplink resource available for the CSI report 1220 to be transmitted (e.g., to the second wireless node 405) . The first wireless node 410 may identify a second replacement time slot for which an uplink resource is available. The second replacement time slot may be a first available time slot for which an uplink resource is available, after the second time slot (e.g.， S4) determined for the CSI report 1220 to be transmitted. For example, the replacement time slot determined (e.g.， identified) to be the first available time slot for which an uplink resource is available may be time slot S8, 4 time slots after the second time slot (e.g.， S4) determined for the CSI report 1220 to be transmitted (e.g., T1+T2+4) . The first wireless node 410 may terminate the second CSI report 1220 if a difference between the second replacement time slot (e.g.， S8) and time slot S1 in which the request for the second CSI report was received at the first wireless node 410 exceeds a latency threshold (e.g.， 6) . In response to determining that the difference (e.g.， 7) exceeds the latency threshold (e.g., 6) the first wireless node 410 may terminate (e.g.， and not transmit) the second CSI report 1220.
