Abstract: Over-the-air (OTA) dynamic time division duplex (TDD) is disclosed with a channel use indicator (CUI) receiver (CUI-R) signal multiplexed in uplink transmissions. According to various aspects, a user equipment (UE) may receive a downlink grant from a serving base station, in which the downlink grant identifies downlink transmissions in one or more subsequent communication slots. The UE may identify a trigger for transmission of a channel usage signal associated with the grant that may be received by neighboring UEs that may potentially interfere. The UE transmits the channel usage signal in a next scheduled uplink region and then receives downlink data from the serving base station according to the downlink grant. If the neighboring UE receives a conditional uplink grant, then it may proceed with uplink transmissions when it fails to detect the channel usage signal from the UE.

Abstract: New radio (NR) shared spectrum (NR-SS) listen before talk (LBT) gap optimizations are disclosed in which an indication, such as the preemption indicator, may provide an indication of a communications gap, in which preemptive communications may occur, to a user equipment (UE) currently engaged in communications, whether the preemptive communications are to another UE or network node or through different signal channels. The gap and preemptive communication may be measured in full symbol lengths, sub-symbol lengths, or interlaces. The communication gap may provide sufficient resources for the preempting node to adequately obtain the shared channel via listen before talk (LBT) procedures, and for the original UE to resume communications after the gap. The communication gap may also be optimally configured in order to provide both the UE and preempting node as much communication resources as possible within the scheduled communication opportunities.

Abstract: Wireless communications systems and methods related to communicating in a communication medium are provided. A first wireless communication device communicates with a second wireless communication device, a first scheduling grant. The first wireless communication device communicates, with the second wireless communication device, a second scheduling grant including at least one of a start slot index (SSI) or a slot format indicator (SFI). The first wireless communication device communicates, with the second wireless communication device, an uplink communication signal based on the first scheduling grant and the second scheduling grant.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support grants for uplink or downlink transmission over multiple transmission time intervals (TTIs). A multi-TTI grant may include a base grant and an extended grant that include separate information and may be transmitted simultaneously (e.g., within the same TTI) or separately. A grant type (e.g., whether a grant is a base grant or an extended grant) or an association between a base grant and an extended grant may be conveyed (e.g., via the multi-TTI grant). A downlink assignment index (DAI) may be included for one or more TTIs subject to the multi-TTI. For instance, DAI may be included for each TTI or for a subset of TTIs.

Abstract: Wireless communications systems and methods related to scheduling and communicating in an uplink direction over a medium shared by multiple network operating entities are provided. A first wireless communication device transmits, to a second wireless communication device, a message indicating an uplink allocation in a transmission slot, the uplink allocation including an allocation size based on an allowable listen-before-talk (LBT) delay in the transmission slot. The first wireless communication device receives, from the second wireless communication device, an uplink communication signal in the transmission slot, the uplink communication signal including an uplink data portion based on the allocation size and a filler portion associated with an LBT delay in the transmission slot.

Abstract: Wireless communications systems and methods related to scheduling and communicating in a frequency spectrum using interlaced frequency resources are provided. A first wireless communication device communicates, with a second wireless communication device, a first interlace configuration indicating a first set of interlaced frequency resources in a frequency band based on a power spectral density (PSD) parameter. The first wireless communication device communicates, with the second wireless communication device, a first frequency resource exclusion configuration. The first wireless communication device communicates, with the second wireless communication device, a first allocation including at least some frequency resources from the first set of interlaced frequency resources based on the first frequency resource exclusion configuration. The first wireless communication device communicates, with the second wireless communication device, a first communication signal based on the first allocation.

An example method includes generating, for a transmission associated with a set of TBs, a bit sequence including TB-level indication of whether each TB in a first subset of TBs includes a retransmission, and CBG-level indication of whether a second subset of TBs includes a CBG-level retransmission, transmitting at least one grant comprising the bit sequence, and transmitting the transmission in accordance with the bit sequence. Another example method includes receiving a grant comprising a bit sequence including a TB-level indication of whether each TB in a first subset of TBs includes a retransmission, and CBG-level indication of whether a second subset of TBs includes a CBG-level retransmission, and monitoring for the set of TBs based at least in part on the bit sequence.
