    Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence. A device or system may monitor a shared spectrum channel for the signature waveform, and when detected, may determine whether the shared spectrum is available for that system, or busy as occupied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Wireless communications systems and methods related to dynamic medium sharing are provided. A first wireless communication device communicates with a second wireless communication device, a reservation request (RRQ) for a transmission opportunity (TXOP) in a shared spectrum. The shared spectrum is shared by a plurality of network operating entities. The first wireless communication device and the second wireless communication device are associated with a first network operating entity of the plurality of network operating entities. The RRQ indicates a first traffic priority of data to be communicated. The first wireless communication device communicates with the second wireless communication device, the data of the first traffic priority during the TXOP.

    Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE. In another aspect, the SFN transmission of the first and second reservation preambles, and the low latency detection methods of the reservation preambles have been disclosed.

    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit a first grant to a UE. The apparatus may determine whether an acknowledgment to the first grant is received. When the acknowledgment to the first grant fails to be received by the apparatus, the apparatus may transmit, to the UE, a second grant including information regarding the first grant. In another aspect, an apparatus may be a UE. The apparatus may receive a first grant. The first grant may include a first Mayday bit. The apparatus may receive a second grant. The second grant may include a TTI count corresponding to a number of unacknowledged TTIs. The second grant may further include a second Mayday bit. The apparatus may determine an acknowledgment based on the TTI count and the first and second Mayday bits.

    Abstract: Reference signals may not uniformly span over time and/or frequency on a resource unit. For example, reference signals may non-uniformly occupy symbols of a subframe. Alternatively, reference signals normally transmitted over certain tones of a subframe may have to be punctured to avoid collisions with a PSS and/or SSS transmitted over the same tones. Consequently, a UE may only be able to use a subset of reference signal tones for performing channel estimation. Accordingly, a method, an apparatus, and a computer program product for wireless communication are provided for improving channel estimation under a non-uniform signal pattern. The apparatus indicates to a UE to utilize a subset of reference signals to derive a channel estimate for demodulating data in a specific subframe, and transmits a plurality of subframes, the plurality of subframes including the reference signals and the specific subframe, the specific subframe including a PSS and/or SSS.

    Abstract translation: 参考信号可能不会在资源单元上的时间和/或频率上均匀地跨越。 例如，参考信号可能不均匀地占据子帧的符号。 或者，通常在子帧的某些音调上发送的参考信号可能必须被打孔以避免与通过相同音调发送的PSS和/或SSS的冲突。 因此，UE可能仅能够使用用于执行信道估计的参考信号音调的子集。 因此，提供了一种用于无线通信的方法，装置和计算机程序产品，用于在非均匀信号模式下改进信道估计。 该设备向UE指示使用参考信号的子集来导出用于在特定子帧中解调数据的信道估计，并且发送包括参考信号和特定子帧的多个子帧，所述特定子帧包括 PSS和/或SSS。
