Abstract: Wireless communication systems and methods related to interference prediction and reporting are provided. A user equipment (UE) obtains a sequence of interference measurements, where each interference measurement in the sequence is obtained at a different measurement time instant. The UE may determine, based on an interference predictor associated with the sequence of interference measurements, one or more predicted channel state information (CSI) values at one or more future time instants. The UE may transmit, to a base station (BS), a report including the one or more predicted CSI values.

Abstract: Wireless communications systems and methods related to dynamically triggering aperiodic CSI reporting are disclosed. A UE may determine whether a condition is satisfied for triggering upon receipt of a signal from a BS. The condition may be based on a decoding status of the signal. In some examples, the UE may explicitly request a CSI resource signal (e.g., CSI-RS, CSI-IM, or both) from the BS when the condition is met. The explicit request may be included in a modified ACK/NACK field, regardless of whether an ACK or NACK is transmitted. The BS may respond with a CSI resource signal. In other examples, the BS may wait to respond with a CSI resource signal until a threshold number of requests are received from the UE. In other examples, the BS may track a number of NACKs from the UE instead of relying upon an explicit request.

Abstract: Methods, systems, and apparatuses for wireless communication are described. In some wireless systems (e.g., new radio (NR) systems), a system may employ fixed or variable length uplink burst regions (e.g., in an uplink-centric slot). The base station may semi-statically or dynamically configure a user equipment (UE) or group of UEs for uplink control channel transmissions within an uplink burst region. In semi-static configuration, the UE may determine the uplink control channel transmission based on values transmitted or indicated via higher-layer signaling or based on default values. In dynamic configuration, the UE may receive an indication of actual resources used by the base station in a physical layer message. The UE may transmit using an uplink control channel transmission based on the indication. In some cases, the base station may allocate code division multiplexing (CDM) groups based on which UEs are semi-statically configured and which are dynamically configured.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that may identify a configuration for channel state information reporting associated with both a first target block error rate and a second target block error rate. The UE may receive one or more reference signals associated with the channel state information reporting. Further, the UE may transmit, to the base station, the channel state information reporting that may include first channel state information for the first target block error rate and second channel state information for the second target block error rate. In some examples, each of the first channel state information and the second channel state information may be based on the received reference signals.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control signaling that includes sounding reference signal (SRS) configuration information associated with an increased quantity of SRS ports. The SRS configuration information may include a quantity of symbols via which to transmit SRSs, a frequency resource comb for each respective symbol, and a threshold quantity of cyclic shifts. The UE may map a first subset of SRS ports to a first symbol and map a second subset of SRS ports to a second symbol. The UE may transmit, and the network entity receive, the SRSs using the first subset of SRS ports via the first symbol according to a first frequency resource comb and respective cyclic shifts and using the second subset of SRS ports via the second symbol according to a second frequency resource comb and respective cyclic shifts.

Abstract: Techniques described provide dependent procedure operation configured for avoiding or mitigating one or more aspect of the impact on the dependent procedure of cancelling an uplink transmission. One or more attributes (e.g., a transmission indication attribute) associated with a cancelled uplink transmission may be designated for dependent procedure operation, such as for indicating whether the cancelled uplink transmission is considered either as having been transmitted or not having been transmitted. The one or more attributes associated with a cancelled uplink transmission designated for dependent procedure operation may be based upon whether the cancelling the first uplink transmission is a fast cancellation or is a slow cancellation. The designation of a transmission indication attribute for dependent procedure operation may correspond to the dependent procedure and/or its operation. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that one or more semi-persistent scheduling (SPS) occasions, within a periodic set of SPS occasions, will be skipped. Accordingly, the UE may refrain from monitoring, for signals from the base station, during the one or more SPS occasions that are skipped. Additionally, in some aspects, the UE may refrain from transmitting, to the base station, acknowledgment feedback associated with the one or more SPS occasions that are skipped. Numerous other aspects are provided.
