Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink grant that does not include a downlink assignment index (DAI); determine a pre-defined bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the pre-defined bundle window. In some aspects, a UE may receive a downlink grant that does not include a DAI; determine a bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI, wherein the bundle window is not pre-defined; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the bundle window. Numerous other aspects are provided.

Abstract: Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for utilizing a one-symbol space-time block code (STBC) process to encode control information for transmission on an uplink control channel. The one-symbol STBC process produces two code blocks, each for transmission on a different antenna. Each code block may be time domain spread across multiple single-carrier frequency division multiple access (SC-FDMA) uplink control channel symbols using the same spreading code to enable recovery of the code blocks at the receiver.

Abstract: Aspects of the present disclosure describe receiving an indication of a covariance matrix from an access point, receiving downlink signaling from the access point, deriving, based at least in part on the covariance matrix or the downlink signaling, one or more precoders for uplink communications over an uplink channel, and indicating, based at least in part on the one or more precoders, uplink channel feedback to the access point.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method for wireless communication. The method includes determining content to include in an uplink control information (UCI) based on a portion of a subframe that includes the UCI. The method further includes transmitting the UCI in the portion of the subframe.

Abstract: Both precoded sounding reference signals (SRS) and unprecoded SRS are transmitted from a UE to an eNB. The UE may transmit both in the same subframe using either TDM or FDM. Or the UE may transmit each in different subframes from each other. The eNB uses some combination of the precoded SRS and the unprecoded SRS in scheduling resources for the UE. The eNB may also provide instruction to the UE for PUSCH precoding for data transmission. The eNB may signal the UE to use the same precoding as for the precoded SRS. The eNB may instead signal the UE to use different precoding by including the precoding information or delta information between the precoding used for the precoded SRS and the selected precoding for the PUSCH data.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a full duplex configuration for using one or more downlink ports and one or more uplink ports simultaneously. The UE may transmit, via the one or more downlink ports, a sounding reference signal (SRS) for downlink channel sounding in a downlink band of a sub-band full duplex (SBFD) slot in accordance with the full duplex configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described technique provide for a user equipment (UE) to selectively transmit an uplink repetition configured with intra-slot frequency hopping during a slot including both sub-band full duplex (SBFD) and non-SBFD symbols. For example, the UE may receive a control message scheduling repetitions of an uplink message and indicating a configuration for intra-slot frequency hopping for the repetitions. In some cases, the UE may selectively transmit a repetition during a mixed symbol slot according to whether the slot is considered available, an alignment of a boundary between the SBFD symbols and non-SBFD symbols of the mixed symbol slot with time resources for portions of the repetition, transmission parameters associated with SBFD symbols and non-SBFD symbols, or any combination thereof.

Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.
