Description

Channel state information report transmission

Background

Communication links between wireless nodes, such as between User Equipment (UE) and a Base Station (BS), may be assisted 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 the BS (and/or one or more other BSs) with one or more CSI. One signal from a BS requesting CSI may be associated with one type and another signal from the BS requesting CSI may be associated with another type. To maintain one or more communication links, the UE may need to calculate and/or generate CSI according to the type associated with the corresponding signal. However, the UE may have limited resources and/or limited capabilities.

Disclosure of Invention

In accordance with the present disclosure, one or more devices and/or methods are provided for facilitating transmission of Channel State Information (CSI) reports. In one example, a first signal containing a request for a CSI report may be received from a wireless node. A second signal may be received from the wireless node. Based on the indication of the setting in the second signal, a setting for CSI reporting may be determined. A time slot for transmitting the CSI report may be determined based on the setting. The CSI report may be transmitted to the wireless node at the time slot.

In one example, a signal containing a request for a CSI report may be received from a wireless node. The settings for CSI reporting may be determined based on applying the number of received requests for channel state information reporting to one or more rules. A time slot for transmitting the CSI report may be determined based on the setting. The CSI report may be transmitted to the wireless node at the time slot.

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

Detailed Description

the subject matter now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and in which certain exemplary embodiments are shown by way of illustration. This description is not intended as an extension or detailed discussion of known concepts. Details that are generally known to those of ordinary skill in the relevant art may have been omitted or may be treated in an overview.

the following subject matter may be implemented in various forms, such as methods, apparatus, components, and/or systems. Accordingly, this subject matter is not intended to be construed as limited to the example embodiments set forth herein. Rather, the example embodiments are provided for illustrative purposes only. Such embodiments may take the form of, for example, hardware, software, firmware, or any combination thereof.

One or more computing devices and/or techniques are provided for facilitating transmission of Channel State Information (CSI) reports. For example, a User Equipment (UE) may connect to a network via a Base Station (BS) of the network (e.g., wireless communication). 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 reliably communicate with the UE and/or at a high data rate (e.g., by enhancing signals transmitted from the BS to the UE based on information in the CSI reports, etc.). The connection between the UE and the BS may involve transmitting several (e.g., a large number) requests from the BS to the UE and/or several (e.g., a large number) CSI reports from the UE to the BS. The number, frequency, and/or kind (e.g., type) of CSI reports generated by the UE may depend on the capability of the UE. Some methods of assisting in transmitting 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 the UE is capable of (e.g., and thus provide less reliable communication between the BS and the UE and/or associated with a lower data rate than possible). Thus, in accordance with one or more techniques provided herein, transmission of CSI reports may be facilitated in a manner that balances interference risk and UE capability to provide optimized communication between a BS (e.g., and/or one or more other BSs) and a UE (e.g., and/or one or more other UEs).

An example method 100 that facilitates transmitting 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 a 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, a first wireless node receives (e.g., from a second wireless node) a first signal containing a request for a CSI report.

In some examples, the request may correspond to a semi-persistent (semi-persistent) CSI configuration. For example, the request corresponding to the semi-persistent CSI configuration may include an activation instruction for periodic transmission of one or more CSI reports (e.g., to the second wireless node). Once activated based on the activation instruction, the first wireless node may transmit an initial CSI report at a certain time slot (e.g., to the second wireless node), and periodically transmit one or more CSI reports (e.g., to the second wireless node) based on 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 on the deactivation instruction, the first wireless node may terminate (e.g., stop) periodic transmission of CSI reports (e.g., to the second wireless node) based on the activation instruction. It may be appreciated that after terminating the periodic transmission of CSI reports based on the activation directive, the first wireless node may continue and/or initiate the periodic transmission of CSI reports based on one or more other activation directives.

In some examples, the request may correspond to an aperiodic CSI configuration. For example, the request corresponding to the aperiodic CSI configuration may contain a trigger for a single transmission of the CSI report (e.g., to the second wireless node). The first wireless node may transmit the CSI report (e.g., only) upon receiving the trigger for the single transmission, and may not transmit more (e.g., other) CSI reports after transmitting the CSI report based on the trigger for the single transmission.

in some examples, the first wireless node may determine a time slot for transmitting the CSI report. The first wireless node may determine the time slot based on the first setting and/or the second setting. For example, the second setting may contain a base value corresponding to a latency associated with transmission of the CSI report (e.g., T1), and/or the first setting may contain an offset value corresponding to a latency offset associated with transmission of the CSI report (e.g., T2).

at 110, the first wireless node may receive a second signal from a second wireless node. In some examples, the second wireless node may generate a 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 on the indication in the second signal about the first setting. In some examples, the second signal may be a Medium Access Control (MAC) -layer signal or a Physical (PHY) layer signal.

The number of triggered but not transmitted CSI reports may be determined based on a difference between the number of triggers received (e.g., by the first wireless node and/or from the second wireless node) and the 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 the threshold, the first setting may be determined to be a first value. The first setting may be determined to be a second value in response to determining that the difference does not exceed the threshold. 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 on the indication in the third signal regarding the second setting. In some examples, the third signal may not explicitly indicate the second setting, and the first wireless node may determine the second setting based on a type of CSI report determined from the third signal (e.g., based on a low resolution beam codebook, a high resolution linear combination codebook, etc.). For example, in an instance in which the first type CSI report is determined based on the third signal, the first value may be determined for the second setting, and in an instance in which the second type CSI report is determined based on the third signal, the 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 on a CSI reporting type determined from the request.

At 120, the first wireless node may determine a time slot for transmitting the CSI report based on 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 a sum of the first setting and the second setting.

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

In some examples, one or more other CSI report transmissions may collide with the transmission of this CSI report on the time slot. For example, one or more other CSI report transmissions may have (the same) time slots as determined for the CSI report transmission. Here, based on determining that the CSI report corresponds to an earlier request than the one or more CSI report transmissions, the CSI report may be transmitted (e.g., in a queued mode) prior to transmitting the one or more other CSI report transmissions. Alternatively, based on determining that the CSI report corresponds to an earlier request than the one or more CSI report transmissions, the CSI report may be transmitted after transmitting the one or more other CSI report transmissions (e.g., in a stack mode).

The one or more other CSI reports may be transmitted in an increasing order according to their corresponding number of requests (e.g., queue mode). For example, in response to determining that the request for CSI report transmission is received before receiving the second request for the second CSI report and the second request is received before receiving the third request for the third CSI report, the first CSI report may be transmitted before the second CSI report transmission and/or the second CSI report may be transmitted before the third CSI report transmission. It will be appreciated that one or more CSI report transmissions other than those corresponding to the second request, the third request, etc. may collide with the CSI report transmission on 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 descending order (e.g., stack mode) according to their corresponding number of requests. For example, in response to determining that the request for CSI report transmission is received before receiving the second request for the second CSI report and the second request is received before receiving the third request for the third CSI report, the third CSI report may be transmitted before the second CSI report transmission and/or the second CSI report may be transmitted before the first CSI report transmission. It will be appreciated that one or more CSI report transmissions other than those corresponding to the second request, the third request, etc. may collide with the CSI report transmission on the time slot and may be processed in a similar manner.

in some examples, such as examples involving Time Division Duplex (TDD) configurations, uplink resources may be available (e.g., required) to (e.g., the first wireless node) so that CSI reports can be transmitted to the second wireless node. In response to determining that the time slot does not have available uplink resources, the first wireless node may identify an alternate time slot in which uplink resources are available and/or may attempt to transmit a CSI report to the second wireless node at the alternate time slot. In some examples, the alternative time slot is a first available time slot after the time slot where uplink resources are available. The first wireless node may terminate transmission of the CSI report if it is determined that a difference between the alternate 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 delay threshold may be greater than or equal to 0.

In some examples involving semi-persistent configuration, the first wireless node may restrict (hold) (e.g., suspend, freeze, etc.) transmission of CSI reports if it is determined 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 restrict transmission of CSI reports during the time when the difference exceeds the threshold and/or may continue or begin transmission of one or more CSI reports upon determining that the difference no longer exceeds the threshold. The threshold may depend on the capabilities of the first wireless node.

In some examples involving aperiodic configurations, the first wireless node may restrict (e.g., suspend, freeze, etc.) transmission of CSI reports if it is determined that a difference between the number of triggers received (e.g., by the first wireless node) and the number of CSI reports transmitted (e.g., from the first wireless node and/or to the second wireless node) exceeds a threshold. The first wireless node may restrict transmission of CSI reports during the time when the difference exceeds the threshold and/or may continue or begin transmission of one or more CSI reports upon determining that the difference no longer exceeds the threshold. The threshold may depend on the capabilities of the first wireless node.

An example method 200 that facilitates transmitting 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 a 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, a first wireless node receives (e.g., from a second wireless node) a first signal containing a request for a CSI report.

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 a first setting based on applying the number of received requests for CSI reports to one or more (e.g., predetermined) 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 active CSI reports (e.g., corresponding to a number of concurrent CSI computations performed by the first wireless node, greater than or equal to 0) to one or more (e.g., predetermined) rules.

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

In some examples, the one or more rules used may correspond to a mode of a semi-persistent CSI configuration associated with the requested CSI report. For example, in an instance in which CSI reports associated with a first mode (e.g., a Frequency Division Duplex (FDD) mode) are requested, a corresponding number of activated CSI reports may be applied to one or more first rules to determine a first setting, while in another instance in which CSI reports associated with a second mode (e.g., a TDD mode) are requested, a 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 on 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 the threshold, the first setting may be determined to be a first value. The first setting may be determined to be a second value in response to determining that the difference does not exceed the threshold. 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 concurrent CSI computations performed by the first wireless node, greater than or equal to 0) to one or more (e.g., predetermined) rules.

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

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

the number of triggered but not transmitted CSI reports may be determined based on 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 the threshold, the first setting may be determined to be a first value. The first setting may be determined to be a second value in response to determining that the difference does not exceed the threshold. 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 on the indication in the second signal about the second setting. In some examples, the second signal may not explicitly indicate the second setting, and the second wireless node may determine the second setting based on a type of CSI report determined from the second signal (e.g., a low resolution beam based codebook, a high resolution linear combination codebook, etc.). For example, in an instance in which the first type CSI report is determined based on the second signal, the first value may be determined for the second setting, and in an instance in which the second type CSI report is determined based on the second signal, the 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 on a CSI reporting type determined from the request.

at 215, the first wireless node may determine a time slot for transmitting the CSI report based on 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 a sum of the first setting and the second setting.

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

in some examples, one or more other CSI report transmissions may collide with the transmission of this CSI report on the time slot. For example, one or more other CSI report transmissions may have (the same) time slots as determined for the CSI report transmission. Here, based on determining that the CSI report corresponds to an earlier request than the one or more CSI report transmissions, the CSI report may be transmitted (e.g., in a queued mode) prior to transmitting the one or more other CSI report transmissions. Alternatively, based on determining that the CSI report corresponds to an earlier request (e.g., stack mode) than the one or more CSI report transmissions, the CSI report may be transmitted after transmitting the one or more other CSI report transmissions.

in some examples, such as examples involving TDD configurations, uplink resources may be available (e.g., required) to (e.g., the first wireless node) so that CSI reports can be transmitted to the second wireless node. In response to determining that the time slot does not have available uplink resources, the first wireless node may identify an alternate time slot in which uplink resources are available and/or may attempt to transmit a CSI report to the second wireless node at the alternate time slot. In some examples, the alternative time slot is a first available time slot after the time slot where uplink resources are available. The first wireless node may terminate transmission of the CSI report if it is determined that a difference between the alternate 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 delay threshold may be greater than or equal to 0.

In some examples involving semi-persistent configuration, the first wireless node may restrict (e.g., suspend, freeze, etc.) transmission of CSI reports if it is determined 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 restrict transmission of CSI reports during the time when the difference exceeds the threshold and/or may continue or begin transmission of one or more CSI reports upon determining that the difference no longer exceeds the threshold. The threshold may depend on the capabilities of the first wireless node.

an example method 300 that facilitates transmitting 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 a 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 on 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., corresponds to a number of concurrent CSI calculations performed by the first wireless node, greater than or equal to 0).

the number of activated CSI reports may be determined based on 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 the threshold, the first setting may be determined to be a first value. The first setting may be determined to be a second value in response to determining that the difference does not exceed the threshold. 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 for one or more (e.g., predetermined) rules (e.g., corresponding to a number of concurrent CSI computations performed by the first wireless node, greater than or equal to 0).

The number of triggered but not transmitted CSI reports may be determined based on 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 the threshold, the first setting may be determined to be a first value. The first setting may be determined to be a second value in response to determining that the difference does not exceed the threshold. 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, a first wireless node may generate a first signal containing a request for a CSI report.

At 315, the first wireless node may generate a second signal containing 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 on the indication in the third signal regarding the second setting. In some examples, the third signal may not explicitly indicate the second setting, instead may indicate and/or be associated with a type of CSI report (e.g., a low resolution beam based codebook, a high resolution linear combination codebook, etc.). The type of CSI report may then be used by the second wireless node to determine the second setting. For example, in instances where the third signal is associated with a first type of CSI report, the first value may be determined by the second wireless node for the second setting, and in instances where the third signal is associated with a second type of CSI report, the second value may be determined by the second wireless node for the second setting. In some examples, rather than using the third signal to determine the second setting, the request may be associated with a type of CSI report, and the second wireless node may determine the second setting based on the type of CSI report determined from the request.

in some examples, a first wireless node may receive a CSI report from a second wireless node over a time slot. The first wireless node and/or the second wireless node may determine a time slot for transmitting the CSI report based on 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 a sum of the first setting and the second setting.

Fig. 4 illustrates an example of a system 400 that facilitates 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 containing a request for a CSI report from the second wireless node 405. Upon receiving the request, the first wireless node 410 may transmit a 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 a first wireless node 410 to a second wireless node 405 in a semi-persistent CSI configuration. For example, the second wireless node 405 may transmit (e.g., in a first signal) to the first wireless node 410 an activation instruction 505 for periodically transmitting (e.g., to the second wireless node 405) one or more CSI reports. Once activated based on the activation instruction 505, the first wireless node 410 may transmit an initial CSI report 510 (e.g., to the second wireless node 405), and may periodically transmit one or more CSI reports (e.g., to the second wireless node 405) based on the (e.g., same) activation instruction 505 after transmitting the initial CSI report 510. For example, after transmitting the initial CSI report 510, the first wireless node 410 may transmit (e.g., to the second wireless node 405) a second CSI report 515 and/or one or more other CSI reports, such as a third CSI report 520. The second wireless node 405 may then transmit a deactivation instruction 525 (e.g., to the first wireless node 410). Once deactivated based on the deactivation instructions 525, the first wireless node 410 may terminate (e.g., stop) periodic transmissions (e.g., to the second wireless node 405) of one or more CSI reports based on the activation instructions 505.

Fig. 6 illustrates an example of a system 600 that facilitates transmission of one or more CSI reports from a first wireless node 410 to a 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 (e.g., in a first signal) first activation instructions 605 for periodically transmitting one or more CSI reports (e.g., to the second wireless node 405). Once activated based on the first activation instruction 605, the first wireless node 410 may transmit a first initial CSI report 610 (e.g., to the second wireless node 405), and may periodically transmit one or more CSI reports based on the (e.g., same) first activation instruction 605 (e.g., to the second wireless node 405) after transmitting the first initial CSI report 610. For example, after transmitting the first initial CSI report 610, the first wireless node 410 may transmit (e.g., to the second wireless node 405) the second CSI report 620. The second wireless node 405 may then transmit (e.g., to the first wireless node 410) a first deactivation instruction 630. Once deactivated based on the first deactivation instruction 630, the first wireless node 410 may terminate (e.g., stop) periodic transmissions (e.g., to the second wireless node 405) of one or more CSI reports based on 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 (e.g., in a second signal) second activation instructions 615 for periodically transmitting 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 on 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 on 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 on the second activation instruction 615. The second wireless node 405 may then transmit (e.g., to the first wireless node 410) a second deactivation instruction 645. Once deactivated based on the second deactivation instructions 645, the first wireless node 410 may terminate (e.g., stop) periodic transmissions (e.g., to the second wireless node 405) of one or more CSI reports based on the second activation instructions 615.

Fig. 7 illustrates an example of a system 700 that facilitates transmission of one or more CSI reports from a first wireless node 410 to a 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 containing a first trigger for a single transmission (e.g., to the second wireless node 405) of a CSI report. Upon receiving the first trigger for a single transmission, the first wireless node 410 may transmit the first CSI report 710 to the second wireless node 405 (e.g., in response to the first trigger). In response to the (same) first trigger, the first wireless node 410 may not transmit 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 that includes a second trigger for a single transmission (e.g., to the second wireless node 405) of a CSI report. 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). In response to the (same) second trigger, the first wireless node 410 may not transmit 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 a first wireless node 410 to a 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 that includes a first trigger for a single transmission (e.g., to the second wireless node 405) of a CSI report. The second wireless node 405 may then transmit (e.g., to the first wireless node 410) a second signal 810 including a second trigger for a single transmission (e.g., to the second wireless node 405) of a CSI report. In response to the first trigger for the single transmission, the first wireless node 410 may transmit (e.g., to the second wireless node 405) the first CSI report 815 after receiving (e.g., by the first wireless node 410) the second signal 810. In response to the (same) first trigger,

The first wireless node 410 may not transmit 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 the second CSI report 820 (e.g., to the second wireless node 405) after transmitting the first CSI report 815 (e.g., to the second wireless node 405). In response to the (same) second trigger, the first wireless node 410 may not transmit 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 a first wireless node 410 to a 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 that includes a trigger for a single transmission (e.g., to the second wireless node 405) of the first CSI report 905. In response to a trigger for a single transmission, a first CSI report 905 corresponding to the trigger may be stored (e.g., computed, processed) within a processor (e.g., UE processor) of the first wireless node 410 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 that include 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 one or more triggers for one or more single transmissions, one or more other CSI reports corresponding to the one or more triggers may be stored (e.g., computed, processed) within 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 (e.g., to the second wireless node 405) of the second CSI report 910. In response to the second trigger for a single transmission, the second CSI report 910 corresponding to the second trigger may be stored (e.g., computed, 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 (e.g., to the second wireless node 405) of the third CSI report 915. In response to the third trigger for a single transmission, a third CSI report 915 corresponding to the third trigger may be stored (e.g., computed, processed) in the processor until it is transmitted (e.g., to the second wireless node 405). Thus, 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., computed, processed) in memory, 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 a first wireless node 410 (not shown in fig. 10A) to a second wireless node 405 (not shown in fig. 10A). In a first time slot S0, the first wireless node 410 may receive (e.g., from the second wireless node 405) a first signal 1005 containing 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 as 5 slots. The second setting (e.g., T1) may be determined by higher layer signaling (e.g., RRC layer) associated with the first signal 1005. Thus, it may be determined that the time slot for the CSI report 1015A to be transmitted (e.g., to the second wireless node 405) may be the time slot S5 or the time slot following time slot S5. In 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 containing a second request for a second CSI report. The second CSI report may not be transmitted until after the seventh time slot S6. In the sixth time slot S5, the 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, a first setting (e.g., T2) for CSI report 1015A may be determined to be a first value (e.g., 1). Thus, the CSI report 1015A may be transmitted (e.g., to the second wireless node 405) a number of slots (e.g., T1+ T2) after the slot (e.g., slot S0) in 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 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 6 slots after slot S0 (e.g., slot S6). It is to be appreciated that the threshold may be based on the capabilities 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 a first wireless node 410 (not shown in fig. 10B) to a second wireless node 405 (not shown in fig. 10B). In a first time slot S0, the first wireless node 410 may receive (e.g., from the second wireless node 405) a first signal 1005 containing 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 as 5 slots. The second setting (e.g., T1) may be determined by higher layer signaling (e.g., RRC layer) associated with the first signal 1005. Thus, it may be determined that the time slot for the CSI report 1015B to be transmitted (e.g., to the second wireless node 405) may be the time slot S5 or the time slot following time slot S5. In 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 containing a second request for a second CSI report. The second CSI report may not be transmitted until after the seventh time slot S6. In 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 CSI report 1015B may be determined to be 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 slots (e.g., T1) after the slot (e.g., slot S0) in which the first signal 1005 was received by the first wireless node 410. The second number of slots may be equal to a second setting (e.g., 5). Thus, the CSI report 1015B may be transmitted 5 slots after slot S0 (e.g., slot S5). It is to be appreciated that the threshold may be based on the capabilities 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 a first wireless node 410 (not shown in fig. 11) to a second wireless node 405 (not shown in fig. 11) in a configuration (e.g., a TDD configuration) that may require uplink resources to be available for CSI reports 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 containing a request for a CSI report 1110. A combination (e.g., sum) of a first setting (e.g., T2) and a second setting (e.g., T1) of the CSI report 1110 corresponding to the request (e.g., T1+ T2) may be determined to be 3 slots. Thus, it may be determined that the time slot 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 be no uplink resources available for CSI report 1110 to be transmitted (e.g., to the second wireless node 405). The first wireless node 410 may identify an alternative time slot in which uplink resources are available. The alternative time slot may be the first available time slot after the time slot (e.g., S3) determined for the CSI report 1110 to be transmitted for which uplink resources are available. For example, the alternative time slot to the first available time slot determined (e.g., identified) to be available for uplink resources may be time slot SN, which may be a number N of time slots after the time slot determined (e.g., S3) for CSI report 1110 to be transmitted. Thus, the CSI report 1110 may be transmitted N slots, slot SN (e.g., T1+ T2+ N), after the slot (e.g., S3) determined for the CSI report 1110 to be transmitted.

fig. 12 illustrates an example of a scenario 1200 corresponding to a system for facilitating transmission of one or more CSI reports from a first wireless node 410 (not shown in fig. 12) to a second wireless node 405 (not shown in fig. 12) in a configuration (e.g., a TDD configuration) that may require uplink resources to be available for CSI reports 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) the first signal 1205 containing the request for the 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 containing a request for a second CSI report 1220. A combination (e.g., sum) of the first setting (e.g., T2) and the second setting (e.g., T1) of the CSI report 1215 corresponding to the request (e.g., T1+ T2) may be determined to be 3 slots. Thus, the time slot in which 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 be no uplink resources available for CSI reports 1215 pending transmission (e.g., to the second wireless node 405). The first wireless node 410 may identify an alternative time slot in which uplink resources are available. The alternative time slot may be the first available time slot after the time slot (e.g., S3) determined for the CSI report 1215 to be transmitted for which uplink resources are available. For example, the alternate slot to the first available slot determined (e.g., identified) to be available for uplink resources may be slot S6, 3 slots (e.g., T1+ T2+3) after the slot determined for the CSI report 1215 to be transmitted (e.g., S3). The first wireless node 410 may terminate the CSI report 1215 if the difference between the alternate time slot (e.g., S6) and the time slot S0 at which the request for a 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).

a sum (e.g., T1+ T2) of a first setting (e.g., T2) and a second setting (e.g., T1) of the second CSI report 1220 corresponding to the second request may be determined to be 3 slots. Thus, the second time slot in which 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 be no uplink resources available for CSI reports 1220 to be transmitted (e.g., to the second wireless node 405). The first wireless node 410 may identify a second alternative time slot in which uplink resources are available. The second alternative time slot may be a first available time slot following the second time slot (e.g., S4) determined for CSI report 1220 to be transmitted for which uplink resources are available. For example, the alternate slot to the first available slot determined (e.g., identified) to be available for uplink resources may be slot S8, 4 slots (e.g., T1+ T2+4) after the slot determined (e.g., S4) for the CSI report 1220 to be transmitted. The first wireless node 410 may terminate the second CSI report 1220 if a difference between the second alternative time slot (e.g., S8) and the time slot S1 at 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.
