Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate support of an extended cyclic prefix (ECP), where a duration of the ECP or transmitting the ECP is based on the indication. In some cases, the UE may receive an uplink grant to transmit an uplink message with an indication of the ECP, and the UE may transmit the ECP and uplink message according to a timeline based in part on the ECP. Additionally or alternatively, an uplink channel allocation indicated in the uplink grant may include a starting point for the ECP, where the UE transmits the ECP at the starting point. In some cases, the UE may multiplex uplink control information (UCI) in the uplink channel based on a timeline that is based in part on the ECP.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with one or more semi-persistent scheduling (SPS) configurations. A base station may transmit a first downlink control information (DCI) transmission to the UE that activates an SPS configuration, and the first DCI may indicate a non-numeric feedback timeline for reporting associated acknowledgment feedback. The base station may transmit a subsequent second DCI transmission that provides feedback resources, and the UE may receive the second DCI and identify timing and resources for SPS acknowledgment feedback based on the second DCI. The UE may then transmit the acknowledgment feedback for one or more SPS transmissions in the feedback resources that are indicated by the second DCI transmission.

Abstract: Wireless communications systems and methods related to performing listen-before-talk (LBT) before a transmission after a link switch in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device receives, from a second wireless communication device, a first communication signal. The first wireless communication device determines a first measurement period in a first portion of a gap duration between the first communication signal and a second communication signal, the first portion being adjacent to a start time of the second communication signal. The first wireless communication device performs an LBT based at least in part on a first channel measurement in the first measurement period. The first wireless communication device transmits, to the second wireless communication device, the second communication signal based on the LBT.

Abstract: Aspects described herein relate to receiving multiple synchronization signal blocks (SSBs) from a cell over a measurement time window, identifying, for each SSB in a subset of the multiple SSBs, a repeating beam index, where the identifying, for each SSB, the repeating beam index is based at least in part on a repeat parameter indicating a number of beams in a SSB pattern for the cell, and associating two or more SSBs of the subset of the multiple SSBs having the same repeating beam index as having a same measurement.

Abstract: Methods, systems, and devices for wireless communications are described that enable efficient group-based acknowledgment feedback reporting. Techniques are provided for feedback for a number of different downlink transmissions to be reported by a user equipment (UE) using transport block level feedback, code block group level feedback, or combinations thereof. Acknowledgment feedback may be provided in one or more group-based or enhanced dynamic feedback reports, a one-shot feedback report, or any combinations thereof.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing paging monitoring by a wireless device. In one aspect, the wireless device may receive a serving cell signal from a cell. The wireless device may determine a delay time based on the serving cell signal. The wireless device may monitor for the paging signal during the determined delay time. The wireless device may stop the monitoring for the paging signal upon or after expiration of the determined delay time. In some aspects, the wireless device may receive an indication of multiple paging signal monitoring occasions from the cell, which may include an indication of a number of synchronization signal blocks (SSBs) to be transmitted from the cell and a number of physical downlink control channel (PDCCH) monitoring occasions per SSB in a paging occasion.

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: Wireless communications systems and methods related to configured transmissions in a shared radio frequency band are provided. A user equipment (UE) receives, from a base station (BS), an indication of a first configured resource in a shared radio frequency band for a communication in a first direction. The UE receives, from the BS, a first configuration to select between a validation of the first direction or an absence of an invalidation of the first direction for using the first configured resource for the communication. The UE communicates, with the BS, the communication in the first direction using the first configured resource based on the first configuration.
