Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to determine an operation state for a user equipment (UE) that corresponds to how the UE applies a preemption indication. The base station may indicate the operation state to the UE using a parameter of a configuration message. The base station may transmit a grant indicating time-frequency resources scheduled for the UE. The UE may identify a priority of a channel associated with the scheduled resources. The base station may determine a number of scheduled resources to be preempted or canceled and may indicate these resources to the UE using a preemption indication. The UE may determine remaining time-frequency resources based on the preemption indication, the priority of the channels, the operation state, or a combination thereof.

Abstract: The aspects described herein may avoid delays and may improve performance at a first apparatus when monitoring a periodic resource pool for an echo signal during a beacon and echo procedure with a second apparatus. The first apparatus transmits a beacon signal using one or more resources in a periodic resource pool, starts a timer, and monitors the periodic resource pool for an echo signal from the second apparatus until expiration of the timer.

Abstract: A base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each PUSCH of the set of PUSCHs comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may generate a coded pseudorandom using an encoder that implements error detection and/or error correction techniques. A bit sequence of information bits may be segmented into a plurality of bit groups, and each bit group may be mapped to a respective symbol to generate a plurality of ordered information symbols. The plurality of ordered information symbols may be encoded (e.g., by the encoder) to generate a plurality of codewords. Each codeword may be demapped to generate a plurality of sequences that are multiplexed to generate the pseudorandom sequence. A signal that is generated based on the pseudorandom sequence may be transmitted by the wireless device. In some examples, the wireless device may generate a reference signal based on orthogonal or pseudo-orthogonal random sequences generated by applying an orthogonal cover code to a pseudorandom sequence.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal identifying a scheduling constraint for the UE, the scheduling constraint for downlink feedback messages associated with a dynamic codebook configuration and scheduled using a first downlink control information (DCI) format. The UE may receive a first DCI having the first DCI format. The UE may determine, based at least in part on the first DCI format, that the scheduling constraint is satisfied. The UE may transmit a feedback message for the first downlink control information based at least in part on the scheduling constraint being satisfied.

Abstract: Aspects presented herein may improve the efficiency and/or the performance of a beacon-echo procedure between sidelink UEs. In one aspect, an apparatus receives, from a base station, at least one of a beacon power level or an echo power level for a beacon-echo procedure. The apparatus transmits, to a second UE, a beacon RS based on the beacon power level. The apparatus receives, from the second UE, an echo RS based on the beacon RS. The apparatus transmits a PSSCH using one or more parameters determined based at least in part on the echo RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on one or more decoding outcomes associated with one or more downlink communications, a resource, of a set of candidate resources, to use for transmitting a channel state information (CSI) report. The UE may transmit the CSI report via the resource. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select at least one of a primary carrier associated with a physical uplink control channel group or a secondary carrier associated with a physical uplink control channel group for transmitting a physical uplink control channel message to a base station. The UE may transmit, based on selecting at least one of the primary carrier or the secondary carrier, the physical uplink control channel message using at least one of the primary carrier or the secondary carrier.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support feedback-related signaling designs that support a feedback mechanism for uplink data transmissions that use or include multiple transport blocks (TBs). The UE may transmit a data message including multiple TBs and a feedback process identifier (ID) corresponding to the data message may be associated with the multiple TBs. If the data message is a configured grant (CG) physical uplink shared channel (PUSCH) transmission, the UE may multiplex uplink control information (UCI) with the data message that indicates feedback-related information for each of the multiple TBs. The network entity may attempt to decode the data message including the multiple TBs and may generate downlink feedback information (DFI) based on whether the network entity successfully decodes one or more of the multiple TBs.
