Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may schedule a user equipment (UE) for multiple transmission/reception point (TRP) communication. The network may transmit a single downlink control information (DCI) message to the UE to dynamically configure multiple transmission configuration indicator (TCI) states for the multiple TRPs. In a first example, the DCI message may include a bit field indicating a set of antenna ports and the multi-TRP scheme for transmission. In a second example, the DCI message may include a separate field indicating the multi-TRP scheme (e.g., based on UE capabilities). In a third example, the DCI may indicate redundancy versions (RVs) for different TRPs in an RV field or across multiple fields. In a fourth example, the DCI may include an indication of a precoding resource block group (PRG) size that may be interpreted differently based on the indicated multi-TRP scheme.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may be used to identify when decoded downlink control information (DCI) is from a combined search space set (e.g., a physical downlink control channel (PDCCH)) candidate of a first search space set and a PDCCH candidate of a second search space set). A UE may receive DCI from a base station, identify PDCCH candidates from a first search space set, a second search space set, and a combined PDCCH candidate from the first and second search space set. The UE may decode the DCI and identify that the decoded DCI corresponds to the combined PDCCH candidate based on various characteristics. In accordance with identifying that the DCI is from a combined PDCCH candidate, the UE and base station may identify various communication channel characteristics such as PDSCH, PUSCH, and PUCCH scheduling information, or rate-matching information, among others.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a current transmission cycle does not satisfy a feedback message transmission criterion for a feedback message to acknowledge whether a transmission was successfully received. The UE may perform a feedback response action on the feedback message based at least in part on determining that the current transmission cycle does not satisfy the feedback message transmission criterion. Numerous other aspects are provided.

Abstract: An apparatus may determine a mode in association with frequency/beam hopping. The mode may be configured semi-statically through RRC signaling and/or dynamically through a MAC-CE. The apparatus may determine the mode based on the RRC signaling/MAC-CE in order to switch between different configurations of frequency and beam hopping for single-beam and multi-beam PUCCH transmissions. The apparatus is configured to receive a PUCCH resource IE for a PUCCH resource indicating a PUCCH resource intra-slot frequency hopping configuration. The apparatus is configured to determine whether multiple PUCCH beams are activated for the PUCCH resource. The apparatus is configured to determine a mode for frequency hopping and beam hopping for the PUCCH resource based on at least one of the PUCCH resource intra-slot frequency hopping configuration, or the determination whether multiple PUCCH beams are activated. The apparatus is configured to transmit on the PUCCH resource based on the determined mode.

Abstract: Techniques and device for wireless communications are described. A wireless device may establish multiple connections with multiple transmission reception points (TRPs). The wireless device may receive downlink control information (DCI) messages from the multiple transmission points and may generate joint hybrid automatic repeat request feedback (HARQ) based on the received downlink control information messages. To support joint HARQ feedback, counter indices may be jointly assigned to the DCI messages generated by the multiple transmission reception points. The method for jointly assigning the DCI messages may be selected based on a level of interference detected in a communications channel. Also, to support joint HARQ feedback, a total counter index in an uplink DCI message may be configured to indicate a total number of DCI message transmitted from a first TRP and a second TRP during a time period.

Abstract: Methods, systems, and devices for sounding reference signal (SRS) resource indicator (SRI) association for configured grant (CG) based transmission and reception point (TRP) physical uplink shared channel (PUSCH) transmission are described. In some examples, a user equipment (UE) may receive first control signaling indicating a first and second sounding reference signal (SRS) resource set associated with a first and second set of power control parameter, respectively. The UE may receive second control signaling indicating a CG configuration, the first and second power control parameters for transmissions in the CG configuration. In some examples, the UE may determine a configuration status for one or more fields the first control signaling, the second control signaling, or both. The UE may select an SRS resource set based on the configuration status and may transmit one or more CG uplink transmissions with the CG configuration using the selected SRS resource set.

Abstract: This disclosure provides methods, devices, and systems supporting power control parameter configuration for configured grants (CGs). In some implementations, a user equipment (UE) may receive control signaling configuring multiple sounding reference signal (SRS) resource sets and multiple sets of power control parameters for CG uplink transmission. The UE may receive downlink control information (DCI) scheduling a retransmission and indicating which set of power control parameters the UE is to use for the CG uplink retransmission. In some other implementations, the control signaling may configure multiple SRS resources sets but a single set of power control parameters. The UE may receive DCI activating the CG configuration or scheduling a retransmission, the DCI indicating a second set of power control parameters not configured by the control signaling. The UE may automatically use the power control parameters configured by the control signaling or may determine a second set based on the DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a group of transmission configuration indicator states including a first subset associated with a first bandwidth part and a second subset associated with a common frequency resource. The UE may determine, based on the group of transmission configuration indicator states, a transmission configuration indicator state list arrangement indicating a first state list associated with the first bandwidth part and a second state list associated with the common frequency resource. The UE may select, based on the transmission configuration indicator state list arrangement, a transmission configuration indicator state sharing scheme or a transmission configuration indicator state separation scheme. The sharing scheme may include at least one transmission configuration indicator state that may be common between a unicast transmission configuration and a multicast transmission configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive, from a network device, a downlink control message that schedules a first and second repetition of a transport block for a downlink shared channel in a first component carrier of multiple component carriers, the first and second repetitions scheduled in a first and second transmission occasion associated with the downlink shared channel. The UE may monitor for the repetitions in the respective transmission occasions, and the UE may decode the transport block based on a number of transmission occasions associated with the downlink shared channel in the component carrier and a data rate limit across the multiple component carriers including the first component carrier.
