Abstract: Certain aspects of the present disclosure provide techniques for replacing and/or fixing broken uplink repetitions due to segmentation of nominal repetitions into actual repetitions. A method that may be performed by a user equipment (UE) includes detecting that a configured repetition pattern for uplink transmission to a network entity results in segmentation of at least one nominal repetition into multiple actual repetitions, modifying the configured repetition pattern, based at least in part on the detection, to avoid segmentation of nominal repetitions into multiple actual repetitions, and sending the uplink transmission to the network entity in accordance with the modified repetition pattern.

Abstract: Aspects are provided which allow a base station to segment a code block into individual code block segments and a UE to determine and indicate a quality of the individual code block segments in a CSI report to a base station. The base station transmits a code block to the UE which includes a plurality of code block segments. The UE determines a code block segment quality of each of the code block segments, and sends a CSI report including one or more of the code block segment qualities to the base station. Thus, the code block segment qualities indicated by the UE allow the base station to determine which segments of the code block should be re-transmitted, for example, based on a best RV to be applied for the code block retransmission, thereby improving retransmission performance.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

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 wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an angle parameter for encoding uplink messages using a fractional Fourier Transform (FrFFT). A base station may transmit a set of angle parameters or a single angle parameter that the UE is to use for encoding an uplink message. The UE may select an alpha value from the set of alpha values for the encoding. The UE may transmit an indication of a set of proposed angle parameters to the base station, and the base station may determine and indicate one of or a subset of the received set of proposed angle parameters to the UE. The base station may indicate a correspondence between angle parameters and beam configurations, and the UE may identify an alpha parameter value based on a subsequently indicated beam configuration.

Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may map hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback that includes a first HARQ-ACK bit associated with a high priority and a second HARQ-ACK bit associated with a low priority to a sequence cyclic shift value that provides an unequal reliability between the first HARQ-ACK bit and the second HARQ-ACK bit. The UE may transmit, to a base station, the HARQ-ACK feedback via a physical uplink control channel (PUCCH) format 0. Numerous other aspects are provided.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement PUCCH resource configuration for two-step RACH for subsequent HARQ messaging. After a UE transmits msgA to a BS, the BS responds with msgB including a PUCCH resource indicator in a DCI of PDCCH, or a PUCCH resource indicator in PDSCH. The UE attempts to decode PDCCH or PDSCH, respectively. Upon decoding, the UE will use the configuration identified by the resource indicator. With the PUCCH resource configuration information, the UE signals a HARQ message.
