Abstract: Aspects relate to mechanisms for increasing the field of view of a spectrometer. An optical device may be configured to simultaneously couple light from different locations (spots) on a sample to the spectrometer to effectively increase the spectrometer field of view. The optical device can include a beam combiner and at least one reflector to reflect light beams from respective spots on the sample towards the beam combiner.

Abstract: 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.

Abstract: 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.

Abstract: Techniques for operator identification on a shared communication medium are disclosed. An access point may determine an operator identifier for an operator associated with an access point and configure a set of resource elements to carry an operator identifier reference signal embedded with the operator identifier. The access point may then transmit the operator identifier reference signal using the configured set of resource elements. An access terminal may receive signaling from an access point on a set of resource elements and monitor the signaling for an operator identifier reference signal. The access terminal may then determine an operator identifier for an operator associated with the access point based on the operator identifier reference signal.

Abstract: 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.

Abstract: Techniques for managing access to a shared communication medium are disclosed. Scheduling grants may be sent to different access terminals for different sets of resources for uplink transmission on the communication medium. A series of re-contention gaps may be scheduled for access terminal contention within or between the different sets of resources. Uplink and downlink transmission on the communication medium may be silenced during each of the series of re-contention gaps. Moreover, an access terminal may receive a scheduling grant that allocates a set of resources to the access terminal for uplink transmission on a communication medium and contend for access to the communication medium based on the scheduling grant. The access terminal may then selectively transmit uplink traffic over the allocated set of resources based on the contending.

Abstract: The present disclosure provides for fast radio resource management procedures for new radio. Generally, a fixed frame structure is utilized and all base stations are synchronized. A base station may transmit a reservation request during a first control slot for the base station in a reservation channel at a beginning of a synchronized frame. A first user equipment may transmit and the base station may receive a reservation response during a second control slot. The base station may receive, from the first UE, after a third control slot of the reservation channel for a neighboring base station, a reservation indication based on a measurement by the first UE of the neighboring base station or at least one other UE associated with the neighboring base station. The base station may determine, based on the resource indication, whether to schedule the first UE during a data channel of the synchronized frame.
