Abstract: Methods, systems, and devices for wireless communication are described that may perform dual stage channel interleaving in which code blocks are interleaved at the code block level and at a symbol level. The interleaved code block data may provide time diversity for the code block data, and the interleaved symbol data may provide frequency diversity for the code block data, thus helping to mitigate narrowband and/or bursty interference. The interleaving within the code block and interleaving within the symbols, in some examples, may allow pipelined implementation of decoding of the code blocks at the receiver, for faster processing. In some cases, systematic data and parity data may be interleaved within the code block data to provide a uniform distribution of the systematic data in time within the code block.

Abstract: A user equipment (UE) may receiving, from a base station, a synchronization signal block (SSB) of a set of quasi-collocated (QCL) SSBs, the SSB comprising an indication of a parameter indicating information associated with a plurality of downlink control channel locations corresponding to the set of QCL SSBs. The UE may determine, based at least in part on the parameter, the plurality of downlink control channel locations corresponding to the set of QCL SSBs. The UE may receive a downlink grant for a system information based at least in part on monitoring one or more downlink control channel locations of the plurality of downlink control channel locations. The UE may receive the system information based at least in part on the downlink grant. The UE may establish a connection with the base station based at least in part on the SSB and the received system information.

Abstract: Various procedures associated with autonomous uplink (AUL) are disclosed. In order to address the mismatch between listen before talk (LBT) and AUL bandwidth a fractional sensing channel is defined less than 20 MHz. Accordingly, a user equipment (UE) may use the fractional sensing channel to perform LBT only on the resources allocated for AUL. Contention window update may further be modified for transmissions spanning multiple transmission opportunities (TxOPs). A contention window update may occur over all transmission channels considering full acknowledgement information of each TxOP, a percentage of acknowledgement information weighted on the number of channels, a percentage of acknowledgement information weighted on the ratio of resources on each channel, or by selecting a primary channel of the multiple channels for the contention window update. In repetition scenarios, the reference transmission for contention window updates may be selected depending on whether all repetitions are within one or multiple TxOPs.

Abstract: Certain aspects of the present disclosure provide techniques for random-access channel (RACH) communication. For example, certain aspects provide a method for falling back from a 2-step RACH procedure to a 4-step RACH procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configuration indicating a transmission configuration indicator (TCI) state switching pattern and a TCI state switching period to a user equipment (UE). The UE may perform TCI state switching according to the TCI state switching pattern and period, and the UE may receive a downlink transmission according to the TCI state switching pattern. The UE may receive a downlink control information (DCI) including an indication of a TCI state for a subsequent TTI. The UE may receive the downlink signal in accordance with both the TCI state switching pattern and the indication in the DCI. The UE may receive a configuration message indicating a first DCI state, receive a DCI indicating a second TCI state for a subsequent TTI, switch to the second TCI state, and receive a downlink signal using the second TCI state.

Abstract: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

Abstract: RESUMEN Se describen métodos, sistemas y dispositivos para usar un canal físico de control de enlace descendente (PDCCH) común para indicar los haces de transmisión que debe usar una estación base durante una oportunidad de transmisión o una periodicidad para monitorear espacios de búsqueda. Un equipo de usuario (UE) puede monitorear un espacio de búsqueda (en algunos casos, usando una periodicidad) para el PDCCH común para determinar si los haces de transmisión asociados con el UE deben usarse durante la oportunidad de transmisión. Si es así, el UE puede despertarse durante al menos una parte de la oportunidad de transmisión para recibir información adicional. Si el PDCCH común indica que no se van a utilizar haces de transmisión asociados con el UE durante la oportunidad de transmisión, el UE puede entrar o volver a entrar en el estado de reposo. El UE puede cambiar a una nueva periodicidad para monitorear el espacio de búsqueda basándose en la información transmitida dentro del PDCCH común.

Abstract: Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.
