Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols indicated by the configuration. The UE may determine a quantity of resource blocks for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols. The UE may transmit, to a base station, the repetition on the second quantity of symbols using the quantity of resource blocks for each repetition with the first quantity of symbols.

Abstract: Certain aspects of the present disclosure provide techniques for skipping or using actual repetitions. A method that may be performed by a user equipment (UE) includes receiving, from a base station, a configuration indicating resources for a first repetition and a second repetition in a physical uplink control channel (PUCCH). In certain aspects, the method may also include transmitting the first repetition, wherein the first repetition includes a larger symbol length than the second repetition, the resources for the first repetition multiplex a plurality of transmissions from first UEs including the UE, the resources for the second repetition multiplex a plurality of transmissions from second UEs, and a quantity of the first UEs is larger than a quantity of the second UEs.

Abstract: A base station (BS) may determine (estimate) a preparation time for at least one uplink (UL) transmission by a user equipment (UE) on at least one radio frequency (RF) carrier. The BS may use the preparation time to ensure that the BS sends a grant for the at least one transmission to the UE a sufficient amount of time before the at least one transmission is scheduled to occur to give the UE sufficient time to conduct the at least one UL transmission. In some examples, the BS determines the preparation time based on adjusting an uplink preparation time according to a defined value. In some examples, the BS determines the preparation time based on a subcarrier spacing (SCS) index. The BS may select the SCS index used to determine the preparation time from smallest of the SCS indexes configured for the different RF carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a default overlap resolution process for application by the UE on a plurality of overlapping transmissions. The plurality of overlapping transmissions may be collectively scheduled by one or more first downlink control information (DCI) messages received by the UE prior to a processing deadline for multiplexing the plurality of overlapping transmissions. The UE may determine, based on the processing deadline having passed, whether any one of the one or more first downlink control information messages includes a second indication of a transmission-specific overlap resolution process for application by the UE on a first two or more overlapping transmissions of the plurality of overlapping transmissions. The UE may perform a determined overlap resolution process including either the transmission-specific overlap resolution process or the default overlap resolution process.

Abstract: A user equipment (UE) determines an occurrence of a triggering event for providing negative acknowledgment (NACK) based feedback for a semi-persistent scheduling (SPS) transmission. The apparatus monitors for the SPS transmission. The apparatus transmits a NACK if the SPS transmission is not successfully received and refrains from sending an ACK if the SPS transmission is successfully received based on the occurrence of the triggering event for providing NACK based feedback. The base station determines an occurrence of a triggering event for a UE to provide NACK based feedback for an SPS transmission. The apparatus transmits the SPS transmission and determines that the UE successfully received the SPS transmission based on an absence of a NACK from the UE for the SPS transmission.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, DCI associated with SPS. The apparatus may also identify whether the DCI is EH SPS activation DCI, EH SPS reactivation DCI, data SPS activation DCI, data SPS reactivation DCI, or SPS release DCI, the EH SPS activation DCI and the EH SPS reactivation DCI corresponding to an EH configuration, the data SPS activation DCI and the data SPS reactivation DCI corresponding to a data processing configuration. Additionally, the apparatus may configure an EH component associated with the EH configuration if the DCI is the EH SPS activation DCI or the EH SPS reactivation DCI, or performing data processing associated with the data processing configuration if the DCI is the data SPS activation DCI or the data SPS reactivation DCI.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may provide for handling of priority indications in scenarios where simultaneous physical uplink control channel (PUCCH)-physical uplink shared channel (PUSCH) is supported. For example, wireless communications systems may configure (e.g., via radio resource control (RRC) signaling) simultaneous PUCCH-PUSCH across two or more carriers, where piggybacking of feedback information on uplink shared channel transmission may be disabled. Further, a grant (e.g., downlink control information (DCI) scheduling a PUSCH transmission) may include a priority index field to indicate a priority associated with a transmission or resources scheduled by the grant. The described techniques may provide for efficient handling of priority indications associated with scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is supported (e.g., techniques are provided for performing or dropping scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is enabled based on any priority indications associated with the overlapping scheduled transmissions).

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DCI content and modified/enhanced codebook Type 3 HARQ PUCCH content for deferred SPS PUCCH ACK/NACK. In aspects, a UE may receive, from a base station, DCI including a request for HARQ-ACK feedback associated with at least one resource that is unavailable. The HARQ-ACK feedback may be based on one or more one-shot HARQ-ACK codebooks including one or more bits. The UE may transmit, to the base station, the HARQ-ACK feedback associated with the at least one resource that is unavailable, where the HARQ-ACK feedback includes the one or more one-shot HARQ-ACK codebooks including the one or more bits.
