摘要： A medium reservation framework is disclosed for coexistence of coordinated and uncoordinated wireless networks in licensed spectrum and shared spectrum. The proposed medium reservation framework organically takes into account operating regimes with different numbers of Tx/Rx antennas per node, provides flexibility in trading off medium contention aggressiveness and power saving, leverages the inherent synchronization nature of NR, and covers both coordinated and uncoordinated operation scenarios. Various aspects of the medium reservation framework may be centered on one or more combinaitons of some basic building blocks, such as an operation grid, synchronization signals, and reservation messages, such as a reservation request signal (RRQ) and one or more a reservation response signals (RRS).

摘要： A method, apparatus, and computer-readable medium at a transmitting network device or a target network device in a listen-before-talk (LBT) session that employ a spatial LBT procedure is disclosed. The spatial LBT procedure takes into account multiple-input multiple-output (MIMO) configuration information in measuring an effective interference. Accordingly, the spatial LBT procedure enables the transmitting network device or the target network device to more accurately measure an interference and make a more accurate decision on whether a channel is clear, and thus improves the system-wide performance. Also, the spatial LBT procedure allows the transmitting network device or the target/receiving network device to adaptively adjust the LBT power detection threshold when the MIMO configuration is not available. This also enables the network devices to more accurately measure interference and make a more accurate decision on whether the channel is clear, especially when advanced MIMO technologies are deployed in 5G or beyond.

摘要： Wireless communication systems and methods related to spectrum use negotiations are provided. A first wireless communication device transmits, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum for a time period. The first wireless communication device receives, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from a first priority to a second priority for accessing the spectrum during the time period. The first wireless communication device communicates with a second wireless communication device in the spectrum during the time period based on the second priority, where at least the first wireless communication device or the second wireless communication device is associated with the local operator.

摘要： Methods, systems, and devices for wireless communication are described. A wireless device may use a subband of a frequency domain channel as a dedicated channel reservation (CR) sub-channel. Wireless devices may both monitor for and transmit CR signals in the CR subband. When not actively transmitting, a wireless device may monitor the CR subband to identify CR signals from other wireless devices. A wireless device communicating using the CR subband may transmit a CR signal and a pre-grant or pre-grant response simultaneously based on an frequency division multiplexing configuration. Multiple channels may share a CR subband. The CR subband may have a pre-configured frequency domain location or be at a configurable frequency in the channel. The data subband and CR subband may have different levels of synchronization, and base stations operating in the wireless communications system may consider data subband synchronization and CR subband synchronization separately.

摘要： Techniques for reservation coordination on a shared communication medium are disclosed. An access point, for example, may contend for access to a communication medium, and transmit a channel reservation message in accordance with a first Radio Access Technology (RAT) to reserve the communication medium for a transmission opportunity (TXOP) duration based on the contending. The access point may then transmit, during the reserved TXOP duration, a reservation coordination signal in accordance with a second RAT to convey reservation coordination information associated with the reserved TXOP duration.

摘要： Precoded contention reservation signals for synchronous new radio (NR) shared spectrum (NR-SS) networks are disclosed. A transmitter that uses precoded contention reservation signals may be configured either to skip or use the training phase for determining rank parameters. The transmitter participates in contention resolution with its receiver by transmitting the precoded contention reservation signals precoded with tentative rank parameters. After contention interval, receiver sends feedback to the transmitter identifying proposed rank parameters based on the strongest precoded contention signals of any neighboring nodes that also won access to the channel. When configured to skip the training phase, the transmitter sets the rank parameters according to the proposed rank parameters. Otherwise, the transmitter participates in the training phase with other winning nodes transmitting signals identifying proposed rank parameters. The receiver then feeds back refined rank parameters to the transmitter based on each of the proposed rank parameters of the training phase.

摘要： An opportunistic asynchronous operation for coordinated new radio (NR) shared spectrum (NR-SS) operations is discussed. In a wireless network having at least one contention-based shared channel in which communications are configured having one or more control intervals time division multiplexed with one or more data intervals for transmission opportunities, a base station receives data for communication at a time during a current data interval on a contention-based shared channel. The base station will review its received signals on the contention-based shared channel during the previous control interval located immediately prior to the current data interval. If none of the received signals indicate a contention-resolution of the contention-based shared channel, the base station may begin an attempted transmission by performing an abbreviated clear channel assessment (CCA). If the CCA is detected as clear, the data may be transmitted.
