Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a resource grant for a data communication within a transmission time interval (TTI). The UE may receive, from the base station, an indication of a control signal configuration and an end symbol index associated with the resource grant. The UE may identify, based at least in part on the received indication, a plurality of symbol positions in the TTI in which reference signals are to be communicated in conjunction with the data communication.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine a Physical Uplink Control Channel (PUCCH) resource for a PUCCH transmission prior to receiving a dedicated PUCCH resource configuration, determining a repetition level for the PUCCH transmission, and transmit the PUCCH transmission, on at least the PUCCH resource, according to the repetition level. A base station may transmit, to a user equipment (UE), information scheduling a Physical Uplink Control Channel (PUCCH) transmission on a PUCCH resource prior to configuring dedicated PUCCH resources for the UE, determine a repetition level for the PUCCH transmission, transmit, to the UE, an indication of the repetition level, and receive, according to the repetition level, a first repetition of the PUCCH transmission on the PUCCH resource and other repetitions of the PUCCH transmission.

Abstract: Methods, systems, and devices for wireless communications are described that support splitting resources among different types of control information and uplink data for transmission on an uplink shared channel. A base station may transmit a grant indicating resource elements (REs) of an uplink shared channel allocated to a user equipment (UE) for an uplink transmission. The UE may process the grant and split the granted REs between different types of uplink control information (UCI) and uplink data based on a reference payload size. The UE may generate an uplink transmission based on the splitting of the REs, and may transmit the uplink transmission in the REs of the uplink shared channel indicated in the grant. The base station may monitor the REs of the uplink shared channel for the uplink transmission in accordance with the splitting of the plurality of REs.

Abstract: Methods, systems, and devices for wireless communications are described that provide multiplexing of one or more control or shared channel communications on one or more uplink component carriers (CCs). Uplink control channel communications may be multiplexed within each CC that is configured for uplink control channel transmissions and, after multiplexing the control channel communications within each CC, multiplexing with shared channel communications may be performed. Multiplexed or un-multiplexed control channel communications may be multiplexed with a shared channel communication on a same or a different CC, where the multiplexing on the same CC or on the different CC is based at least in part on a configuration associated with concurrent shared channel and control channel communications. Further a priority associated with one or more of the shared channel communications or the control channel communications may be used to determine channels to multiplex together on a CC.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may transmit a message indicating a capability of the UE to support power splitting for signals received at the UE for EH by the UE. In some examples, the UE may transmit, based on the capability of the UE to support power splitting, an indication of a power splitting factor for EH by the UE, the power splitting factor indicating a portion of received power for signals received at the UE to be used for EH. The UE may receive a signal to use for power splitting based at least in part on the capability of the UE to support power splitting for signals received at the UE for EH by the UE and the power splitting factor.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A first network node may receive, from a second network node, downlink control information based on monitoring at least one of a first physical downlink control channel candidate or a second physical downlink control channel candidate that are linked for physical downlink control channel repetition. In some examples, the second physical downlink control channel candidate may end later in time than the first physical downlink control channel candidate. The first network node may identify an absence of a scheduled physical downlink shared channel based on the downlink control information. The first network node may then transmit, to the base station, a feedback message in response to the downlink control information at least a threshold number of time units after the second physical downlink control channel candidate.

Abstract: Certain aspects of the present disclosure provide techniques for handling delayed sounding reference signal (SRS) transmission. A user equipment may be configured to receive, from a network, at least one SRS parameter and a first downlink control information (DCI), wherein the first DCI includes a first request for transmission of a first SRS; identify a first slot for transmission of the first SRS based on said at least one SRS parameter and the first DCI; determine that the first slot is not available for transmission of the first SRS; identify a second slot for transmission of the first SRS in response to the determining that the first slot is not available for transmission of the first SRS; determine a maximum SRS delay associated with the first SRS; and determine whether to transmit the first SRS in the second slot based on the maximum SRS delay.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, an indication of a configuration for transmitting subslot-based feedback messages (e.g., via an uplink channel) associated with downlink transmissions (e.g., received via a downlink channel). In some cases, the UE and base station may generate a feedback codebook for the feedback messages according to a subslot-based codebook generation procedure. For example, the UE and base station may generate the feedback codebook based on a quantity of downlink transmission opportunities ending during each subslot of the uplink channel. The UE may then transmit, to the base station via the uplink channel, the feedback messages in accordance with the feedback codebook.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of physical uplink control channel (PUCCH) resources to be used to transmit a channel state information (CSI) payload based at least in part on a first rank that is independent of a second rank used to construct the CSI payload; and transmit the CSI payload, to a base station (BS), using one or more resources from the set of PUCCH resources. Numerous other aspects are provided.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.
