A user equipment (UE) may identify, based on attributes of an uplink control information (UCI) message transmitted by the UE to a base station, whether transmitting the UCI message will trigger a feedback message from the base station. The UE may transmit the UCI message to a base station in uplink control channel resources. The UE may determine a feedback configuration corresponding to the UCI message based on attributes of the UCI message. The feedback configuration may indicate whether the UCI triggers a feedback message. The UE may monitor for the feedback message responsive to the UCI message based on the feedback configuration.

DETAILED DESCRIPTION

In some wireless communications systems, data channels or control channels may carry information and indicators from a user equipment (UE), such as uplink control information (UCI) messages, to a base station. The UCI messages may support the scheduling of uplink shared channel transmissions (e.g., physical uplink shared channel (PUSCH) transmissions). In some examples, a UE may transmit a UCI report to a base station. The UCI report may include, for example, hybrid automatic repeat request (HARQ) feedback information (e.g., an positive acknowledgement (ACK) or negative acknowledgement (NACK)) regarding a downlink data channel transmission (e.g., a physical downlink scheduled channel (PDSCH) transmission) or a downlink control channel transmit (e.g., a physical downlink control channel (PDCCH) transmission). In some cases, the UCI report may include a scheduling request or a channel state information (CSI) report.

In some cases, the UE may transmit the UCI report over an uplink shared channel (e.g., PUSCH) transmission. The UE may receive, from the base station, signaling which may serve as ACK feedback for the UCI report carried over the PUSCH transmission. For example, the UE may receive downlink feedback information (DFI) from the base station over downlink control information (DCI) (e.g., DCI format 0_1 to convey ACK/NACK feedback for a configured grant (CG) PUSCH transmission). In some examples, the DFI may include a 16 bit field mapping respectively corresponding to, for example, up to 16 HARQ processes for the CG PUSCH transmission. In another example, the UE may receive a grant for an additional PUSCH transmission having the same HARQ identifier as the PUSCH transmission carrying the UCI report. The UE may regard the DFI or the grant for the additional PUSCH transmission as ACK feedback (e.g., an acknowledgement that the base station received the UCI report).

In some other cases, the UE may transmit the UCI report over an uplink control channel (e.g., physical uplink control channel (PUCCH)) transmission. However, some systems may not support dedicated feedback (e.g., ACK/NACK) for UCI reports transmitted over a PUCCH transmission. Such cases, for example, may prevent autonomous state changes (e.g., changes to a transmission configuration indicator (TCI) state) to be triggered at the UE or the base station. For example, without a dedicated feedback (e.g., ACK/NACK) for UCI reports transmitted by the UE over a PUCCH transmission, the UE may be unable to confirm whether the base station has successfully received the UCI report (and accordingly, switched to a different TCI state). For example, without the confirmation, the UE may be unable to determine whether to also switch to the different TCI state.

In some examples, some UCI reports transmitted over a PUSCH transmission or a PUCCH transmission may trigger an autonomous state change in the UE or the base station. For example, a CSI report may autonomously trigger a TCI update for a PDSCH or a CSI-reference signal (RS). In another example, a panel related report (e.g., a panel update report) may trigger autonomous switching on and off of an antenna panel of the UE or the base station. In some other examples, an uplink beam report due to maximum permissible exposure (MPE) conditions may trigger autonomous switching of a beam or antenna panel used by the UE or the base station. Accordingly, providing the UE with an indication (e.g., ACK/NACK feedback) of whether a transmitted UCI report has been successfully conveyed to the base station may provide optimization for communications between the UE and the base station (e.g., reducing latency).

According to examples of aspects described herein, a UE may identify, based on attributes of a UCI message transmitted by the UE to a base station, whether transmitting the UCI message will trigger a feedback message from the base station. In an example, the UE may transmit a UCI message to a base station in uplink control channel resources. For example, the UE may transmit the UCI message over a PUCCH transmission. The UE may determine a feedback configuration corresponding to the UCI message based on attributes of the UCI message. In some aspects, the feedback configuration may indicate whether the UCI message triggers a feedback message from the base station. The UE may monitor for the feedback message responsive to the UCI message based on the feedback configuration.

In some examples, the base station may determine the feedback configuration based on receiving the UCI message. For example, the base station may determine the feedback configuration corresponding to the UCI message based on attributes of the UCI message. In an example, the base station may transmit (and the UE may receive) the feedback message based on the feedback configuration. In some aspects, based on receiving the feedback message, the UE may perform an autonomous state change based on receiving the feedback message.

In some other aspects, the attributes of the UCI message may define whether transmitting a UCI message will trigger an autonomous state change at the UE. For example, the attributes may include a trigger condition for triggering an autonomous state change at the UE based on transmission of the UCI message. In some other aspects, the attributes of the UCI message may define whether the UCI message will trigger an autonomous state change at the base station. For example, the attributes may include a trigger condition for triggering an autonomous state change at the base station based on the base station receiving the UCI message.

In some aspects, the attributes may include a format of the UCI message. In some examples, the attributes may include a payload size associated with the UCI message. For example, the attributes may include a PUCCH format associated with a relatively large payload size. In another example, the attributes may include a PUCCH format associated with a relatively small payload size.

In some other aspects, the attributes may include a priority of the uplink control channel resources. In some examples, the attributes may include an indication of a high priority or a low priority the UCI message. For example, the attributes may indicate a relatively high priority for the payload of the UCI message. In another example, the attributes may indicate a relatively low priority for the payload of the UCI message. Additional example aspects of the attributes and the feedback message are described herein.

Aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in spectral efficiency and reliability, among other advantages. In some aspects, determining a feedback configuration corresponding to an UCI message transmitted over uplink control channel resources (e.g., a PUCCH transmission) based on attributes of the UCI message may optimize processing overhead at a UE. For example, by identifying whether the UCI message triggers a feedback message, the UE may determine whether to monitor for the feedback message, optimizing both processing and power overhead.

Aspects of the disclosure are initially described in the context of a wireless communications system. Examples of processes and signaling exchanges that support feedback configuration for uplink control messages are then described. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to feedback configuration for uplink control messages.

According to examples of aspects described herein, a UE115may identify, based on attributes of a UCI message transmitted by the UE115to a base station105, whether transmitting the UCI message will trigger a feedback message from the base station105. In an example, the UE115may transmit a UCI message to a base station105in uplink control channel resources. For example, the UE115may transmit the UCI message over a PUCCH transmission. The UE115may determine a feedback configuration corresponding to the UCI message based on attributes of the UCI message. In some aspects, the feedback configuration may indicate whether the UCI message triggers a feedback message. The UE115may monitor for the feedback message responsive to the UCI message based on the feedback configuration.

In some examples, the base station105may determine the feedback configuration based on receiving the UCI message. For example, the base station105may determine the feedback configuration corresponding to the UCI message based on attributes of the UCI message. In an example, the base station105may transmit (and the UE115may receive) the feedback message based on the feedback configuration. In some aspects, based on receiving the feedback message, the UE115may perform an autonomous state change based on receiving the feedback message.

In some other aspects, the attributes of the UCI message may define whether transmitting a UCI message will trigger an autonomous state change at the UE115. For example, the attributes may include a trigger condition for triggering an autonomous state change at the UE115based on transmission of the UCI message. In some other aspects, the attributes of the UCI message may define whether the UCI message will trigger an autonomous state change at the base station105. For example, the attributes may include a trigger condition for triggering an autonomous state change at the base station105based on the base station105receiving the UCI message.

The attributes may include a format of the UCI message. In some examples, the attributes may include a payload size associated with the UCI message. For example, the attributes may include a PUCCH format associated with a relatively large payload size. In another example, the attributes may include a PUCCH format associated with a relatively small payload size.

The attributes may include a priority of the uplink control channel resources. In some examples, the attributes may include an indication of a high priority or a low priority the UCI message. For example, the attributes may indicate a relatively high priority for the payload of the UCI message. In another example, the attributes may indicate a relatively low priority for the payload of the UCI message. Additional example aspects of the attributes and the feedback message are described herein.

Aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in spectral efficiency and reliability, among other advantages. In some aspects, determining a feedback configuration corresponding to an UCI message transmitted over uplink control channel resources (e.g., a PUCCH transmission) based on attributes of the UCI message may optimize processing overhead at a UE115. For example, by identifying whether the UCI message triggers a feedback message, the UE115may determine whether to monitor for the feedback message, optimizing both processing and power overhead. In some examples, by identifying whether attributes of the feedback configuration include a trigger condition for triggering an autonomous state change at the UE115based on transmission of the UCI message, the UE115may further achieve optimizations in both processing and power overhead.

FIG.2illustrates an example of a wireless communications system200that supports feedback configuration for uplink control messages in accordance with aspects of the present disclosure. In some examples, wireless communications system200may implement aspects of wireless communication system100and may include a UE115-aand a base station105-a, which may be examples of a UE115and a base station105, respectively, described with reference toFIG.1.

As discussed with reference toFIG.2, the UE115-amay identify, based on attributes of a UCI message205transmitted by the UE115-ato a base station105-a, whether transmitting the UCI message205will trigger a feedback message from the base station105-a. In an example, the UE115-amay transmit a UCI message205to a base station105-ain uplink control channel resources. For example, the UE115-amay transmit the UCI message205over PUCCH resources (e.g., a PUCCH transmission). The UE115-amay determine a feedback configuration215corresponding to the UCI message205based on attributes of the UCI message205. In some aspects, the feedback configuration215may indicate whether the UCI205triggers a feedback message210. The UE115-amay monitor for the feedback message210responsive to the UCI message205based on the feedback configuration215.

In some examples, the base station105-amay determine the feedback configuration215based on receiving the UCI message205. For example, the base station105-amay determine the feedback configuration215corresponding to the UCI message205based on attributes of the UCI message205. In an example, the base station105-amay transmit (and the UE115-amay receive) the feedback message210based on the feedback configuration215. In some aspects, the base station105-amay transmit the feedback message210to the UE115-aafter successful decoding of the UCI message205. In some examples, the base station105-amay transmit the feedback message210over DCI (e.g., in a DCI message). For example, the base station105-amay transmit the feedback message210in a DCI message over downlink control channel resources (e.g., PDCCH resources).

In some aspects, the feedback message210may be a dedicated field according to a DCI format of the DCI message. In some examples, bitmap information in a field of the DCI message may include an indication of an association between the feedback message210and the UCI message205. In an example, the DCI may reuse a portion of an existing DCI format (e.g., downlink DCI format 1_0, 1_1, or 1_2) and a field (e.g., reserved field) or fields of the DCI format may include the bitmap information indicating to the association.

In another example, the DCI format may be different from the existing DCI format (e.g., downlink DCI format 1_0, 1_1, or 1_2), and a portion of the DCI format may include the bitmap field. In some aspects, the UE115-amay configure the DCI in dedicated search spaces in a CORESET. For example, the UE115-amay be configured with dedicated candidate tones to receive the DCI.

In some aspects, the UE115-amay perform an autonomous state change based on receiving the feedback message210. In some other aspects, the UE115-amay perform an autonomous state change based on the attributes of the UCI message205, or based on transmitting the UCI message205. For example, the attributes of the UCI message205may define whether transmitting a UCI message205will trigger an autonomous state change at the UE115-a.

In an example, the attributes may include a trigger condition for triggering an autonomous state change at the UE115-abased on transmission of the UCI message205. In some examples, the attributes of the UCI message205may define whether the receipt of the UCI message205will trigger an autonomous state change at the base station105-a. For example, the attributes may include a trigger condition for triggering an autonomous state change at the base station105-abased on the base station105-areceiving the UCI message205.

In some aspects, the attributes may include a format of the UCI message205. For example, the attributes may include a payload size associated with the UCI message205. In an example, the attributes may include a PUCCH format. In some examples, the PUCCH format may be associated with a relatively small payload size (e.g., the UCI message205may be a relatively short PUCCH transmission). In another example, the PUCCH format may be associated with a relatively large payload size (e.g., the UCI message205may be a relatively long PUCCH transmission).

In some aspects, the attributes may include a priority of the uplink control channel resources. In some examples, the attributes may include an indication of a relatively high priority or low priority of the UCI message205. For example, the attributes may indicate a relatively high priority for the payload of the UCI message205. In another example, the attributes may indicate a relatively low priority for the payload of the UCI message205. In some aspects, the UCI message205may be a PUCCH transmission, and a field in the PUCCH transmission may indicate the priority thereof.

In an example, for a UCI message205having a relatively high priority, the UE115-amay expect or monitor for a feedback message210. Additionally, or alternatively, for a UCI message205having a relatively low priority, the UE115-amay not expect or may refrain from monitoring for a feedback message210. In an example, the base station105-amay transmit a feedback message210for a UCI message205having a relatively high priority. Additionally, or alternatively, the base station105-amay refrain from transmitting a feedback message210for a UCI message205having a relatively low priority.

In some aspects, the attributes may include a dynamic indication of the feedback configuration for the UCI message205. For example, the base station105-amay dynamically configure whether transmission of the UCI message205should expect a corresponding feedback message210. In some aspects, the base station105-amay provide dynamic configuration with reference to a table communicated by the base station105-aover RRC signaling.

In some aspects, the attributes may include a scheduling type associated with the uplink control channel resources. The scheduling type may be, for example, a semi-persistent scheduling (SPS) type or a dynamic scheduling type. In an example in which the scheduling type is an SPS type, the UE115-amay transmit UCI messages (e.g., UCI message205) in accordance with a semi-persistent schedule configured by the base station105-a. The UE115-amay expect or monitor for feedback messages (e.g., feedback message210) for UCI messages (e.g., UCI message205) transmitted in accordance with the semi-persistent schedule.

In another example, in which the scheduling type is dynamic, the UE115-amay receive a first DCI message from the base station105-aincluding a first scheduling grant for transmitting the UCI message205. The UE115-amay transmit the UCI message205in accordance with the first scheduling grant. In an example, if the base station105-adoes not receive or does not successfully decode the UCI message205, the base station105-amay transmit a second DCI message including a second scheduling grant for a subsequent transmission (e.g., retransmission) of the UCI message205. In some aspects, the UE115-amay regard the second DCI message as a NACK associated with the first transmission of the UCI message205.

In some aspects, the UE115-amay assume that the first transmission of the UCI message205is successfully received or decoded at the base station105-a, based on a timer (e.g., duration) following the first transmission of the UCI message205. For example, if by the expiration of the timer (e.g., end of the duration), the UE115-adoes not receive a second scheduling grant for a subsequent transmission (e.g., retransmission) of the UCI message205, the UE115-amay assume that the first transmission of the UCI message205was successfully received or decoded at the base station105-a. In an example, the UE115-amay perform an autonomous state change based on the expiration of the timer.

The feedback message210may include an indication of an association between the feedback message210and the UCI message205. For example, the UE115-amay transmit multiple UCI messages (e.g., UCI message205and other UCI messages), and the base station105-amay transmit multiple feedback messages (e.g., feedback message210and other feedback messages) corresponding to the UCI messages. Each of the feedback messages may include an indication of an association between the feedback message and a corresponding UCI message. In an example, the UE115-amay determine that the feedback message210corresponds to the UCI message205based on the indication.

In an example, the feedback message210may include DCI including bitmap information. The bitmap information may correspond to the uplink control channel resources (e.g., PUCCH resources) over which the UE115-atransmitted the UCI message205. In another example, in which the UCI message205includes a CSI measurement or a report configuration, the bitmap information may be associated with an identifier for the CSI measurement or a report configuration. In some aspects, the base station105-amay transmit RRC signaling to the UE115-ainclusive of a configuration of the bitmap. For example, the base station105-amay configure (e.g., preconfigure) the bitmap using RRC signaling.

In some other aspects, the UE115-amay identify an association between the feedback message210and the UCI message205based on a duration (e.g., time offset) between transmitting the UCI message205and receiving the feedback message210. In some aspects, the duration may be fixed. In some other aspects, the duration may be varied or modified.

FIG.3illustrates an example of a process flow300that supports feedback configuration for uplink control messages in accordance with aspects of the present disclosure. In some examples, process flow300may implement aspects of wireless communications systems100or200. Additionally, process flow300may implement aspects of a UCI message205(in which the UCI message205includes a CSI report) and a corresponding feedback message210(e.g., an ACK), as described with reference toFIG.2.

For example, process flow300may include example aspects of updating a CSI-RS beam based on an earlier CSI report (e.g., a previously transmitted UCI message including the CSI report) and a corresponding feedback message (e.g., an ACK). Further, process flow300may be implemented by a UE115-band a base station105-b, which may be examples of a UE115, a UE115-a, a base station105, and a base station105-adescribed with reference toFIGS.1and2.

In the following description of the process flow300, the operations between UE115-band base station105-bmay be transmitted in a different order than the order shown, or the operations performed by base station105-band UE115-bmay be performed in different orders or at different times. Certain operations may also be left out of the process flow300, or other operations may be added to the process flow300. It is to be understood that while base station105-band UE115-bare shown performing a number of the operations of process flow300, any wireless device may perform the operations shown.

At305, the base station105-bmay transmit signaling indication configurations for P2 procedures (e.g., beam refinement for transmit beams of the base station105-b, during which the base station105-bmay transmit a series (e.g., a sweep) of transmit beams and the UE115-bmay provide a CSI report regarding the sweep) and P3 procedures (e.g., beam refinement for receive beams of the UE115-b, during which the UE115-bmay perform a sweep of receive beams while the base station105-btransmits a constant transmit beam). The signaling may include configurations for providing the P2 procedures report to the base station105-b.

At310, the base station105-bmay transmit a single grant for triggering the P2 procedures and the P3 procedures. In an example, the grant may trigger a CSI-RS for the P3 procedures and a CSI report for the P2 procedures. In some aspects, when configuring the CSI-RS for the P3 procedures, the TCI state may be pointed (e.g., temporarily) to a beam associated with a previous P1 procedure (e.g., a beam selected by the UE115-bbased on a beam sweep by the base station105-b). For example, the TCI state may be pointed (e.g., temporarily) to a source RS of the beams associated with the P2 procedures.

At320, the UE115-bmay provide a P2 report (e.g., reporting of a best transmit beam determined by the UE115-b) to the base station105-b. The P2 report may be referred to herein as a P2 beam report. The P2 report may include a CSI report.

At325, the UE115-bmay wait or monitor for a feedback message (e.g., ACK) corresponding to the P2 report. For example, the UE115-bmay wait or monitor for the feedback message (e.g., ACK) based on transmitting the P2 report (e.g., CSI report).

At330, the UE115-bmay receive a feedback message (e.g., ACK) from the base station105-b.

In some examples, the UE115-bmay retransmit the P2 report (e.g., CSI report) based on an expiration of a timer. In some aspects, the timer may begin after the UE115-btransmits the P2 report (e.g., CSI report) at320. In some examples, the UE115-bmay retransmit the P2 report (e.g., CSI report) in a next available reporting occasion.

At335, the UE115-bmay perform an autonomous state change based on receiving the feedback message (e.g., ACK). For example, after receiving the ACK, the UE115-bmay perform the autonomous TCI state update based on the P2 report. In an example, the UE115-bmay autonomously update the TCI state of the P3 CSI-RS (e.g., CSI-RS for the P3 procedures) based on the P2 report and a rule (e.g., the best transmit beam (with respect to a measurement) in the P2 report). In some aspects, if UE115-bdoes not receive the feedback message (e.g., ACK) for the P2 report (e.g., CSI report), the UE115-bmay refrain from perform the autonomous TCI state update.

At340, based on receiving the P2 report, the base station105-bmay perform the same update as the UE115-baccording to the same rule followed by the UE115-b(e.g., the best transmit beam (with respect to a measurement) in the P2 report).

At345, the base station105-bmay perform P3 procedures (P3 sweep of a CSI-RS) based on the updated TCI state of the P3 (e.g., the updated CSI-RS configuration).

The example techniques described herein provide advantages over some systems, for example, in which the UE115-bmay be unaware of whether the P2 report has been successfully received or decoded by the base station105-b. For example, in some other systems, the UE115-bmay assume the P2 report has been successfully received or decoded by the base station105-b, but the base station105-bmay have not received the P2 report. In such example cases, the UE115-band the base station105-bmay be operating according to different TCI state configurations. For example, in some other systems, the UE115-bmay transition to the different TCI state based on the assumption that the base station105-bsuccessfully received the P2 report, whereas the base station105-bmay have refrained from transitioning to the different TCI state (e.g., due to unsuccessful receipt or unsuccessful decoding of the P2 report).
