Abstract: Wireless communication devices, systems, and methods related to downlink control information (DCI) designs for multi-component carrier scheduling are provided. For example, a method of wireless communication can include receiving a downlink control information (DCI) message having a DCI format, the DCI message scheduling a downlink data communication over a single component carrier or multiple component carriers; determining, based on the received DCI message, whether the downlink data communication is scheduled over the single component carrier or the multiple component carriers; and receiving, based on the determining, the downlink data communication over the single component carrier or the multiple component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink payload in a wireless communications system. The UE may identify a set of sequences configured for conveying a payload including a set of bits, where each sequence of the set of sequences is orthogonal to each other sequence of the set of sequences. The UE may select a first sequence from the set of sequences based on a mapping between the set of sequences and payload values corresponding to the set of bits. The UE may transmit the payload including the set of bits using the first sequence.

Abstract: Quasi-colocation (QCL) indication is discussed after downlink transmission. In the management of multiple transmission-reception point (TRP) downlink transmissions, a second indication of a QCL assumption for a particular downlink transmission may be transmitted to receiving user equipment (UEs) after transmission of the downlink transmission. Once a TRP passes a listen before talk (LBT) procedure in a first time interval, it may send a first downlink control information (DCI) with indication of a first QCL assumption for the transmission in the first time interval. The TRP then transmits the downlink transmission intended for part of the multi-TRP downlink transmission. Upon receiving an indication that another of the TRPs was unsuccessful in its part of the multi-TRP transmission, the TRP may transmit a second DCI in a subsequent time interval with adjustments to the QCL assumption for the UEs to use in processing the downlink transmission from the first time interval.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a demodulation reference signal (DMRS) bundling set. The UE may determine whether a physical downlink shared channel (PDSCH) received in a slot is bundled with one or more other PDSCHs in the DMRS bundling set based at least in part on downlink control information. The UE may demodulate the PDSCH based at least in part on a same precoder used for the one or more other PDSCHs in the DMRS bundling set. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for configuring and signaling repetition transmissions of broadcast system information on downlink (DL) channels. In some implementations, a user equipment (UE) may receive an indication of a repetition configuration for broadcast information carried on a physical downlink shared channel (PDSCH), may identify a number of slots configured to carry the broadcast information on the PDSCH based at least in part on the repetition configuration, and may receive the broadcast information carried on the PDSCH in the number of identified slots.

Abstract: In some aspects, multi-slot transport block (TB) configurations for communicating data between wireless devices, such as between a base station and a user equipment (UE), in a wireless communication system are described. Some examples of multi-slot configurations enable the communication of large payloads. For example, an application of a wireless device may jointly process data from a large file or other large set of packets. In such examples, the wireless device transmitting the large file may utilize a multi-slot TB including multiple TB segments corresponding to respective slots of a transmission. Similarly, a wireless device receiving the large file may utilize the multi-slot TB configuration for receiving the data.
