Abstract: 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.

Abstract: Methods, systems, and devices for wireless communication are described that provide for a base station to use frequency hopping for cell acquisition according to a frequency hopping pattern. The frequency hopping pattern may include a set of anchor channels and a set of non-anchor channels used by a base station to communicate with wireless devices. The base station may occupy an anchor channel more often than a non-anchor channel and may transmit acquisition signals using the anchor channel. The anchor channel may also be used by the base station and a user equipment (UE) to exchange paging information, positioning information, random access resources, location of other channels, etc.

Abstract: Soft channel reservation in shared spectrum networks is discussed. In network areas where multiple wireless nodes, whether from the same or different network operators, share spectrum using a channel reservation signaling form of contention resolution, an aggressor transmitter listens for a neighbor receiver's receiver channel reservation signal to the neighbor transmitter the neighbor receiver is in communication with. The receiver channel reservation signal includes channel condition information that the aggressor transmitter can use to estimate an interference impact at the neighbor receiver should the aggressor transmitter performs its transmissions to its own receivers. Based on whether this estimated interference impact exceeds or remains within a particular threshold, the aggressor transmitter may decide whether or not to back off of its transmissions until a later time.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes receiving an instance of a discovery reference signal (DRS) on a beam over a shared radio frequency spectrum band; determining a public land mobile network identifier (PLMN ID) based at least in part on a time-frequency location of the instance of the DRS; and selectively performing a random access procedure based at least in part on the determined PLMN ID. A method for wireless communication at a base station includes transmitting an instance of a DRS on a beam over a shared radio frequency spectrum band; and transmitting a PLMN ID based at least in part on a time-frequency location of the DRS.

Abstract: Positioning techniques for wireless communications devices using shared radio frequency spectrum are provided that may enhance positioning determination for devices operating using shared radio frequency spectrum. Various disclosed techniques provide for identifying determining one or more parameters for a positioning procedure for a UE based on characteristics of shared radio frequency spectrum transmissions. Such parameters may include, for example, frequency information for positioning transmissions or frequency hopping patterns. In some cases, a base station may transmit multiple positioning transmissions that have different coverage levels. In some cases, a UE may transmit an uplink positioning signal that may be received by multiple base stations and used for UE position determination. In some cases, a UE may be configured to monitor for a positioning transmissions on a dedicated frequency, and report measurements associated with the positioning transmissions using a shared frequency.

The first message may include a pre-grant communication and a plurality of downlink beam refinement reference signals (D-BRRSs). The base station may receive a second message from the UE in response to the first message. The second message may include a pre-grant acknowledgement and a plurality of uplink beam refinement reference signals (U-BRRSs). The base station may transmit, using a second base station beam, a third message to the UE. A width of the second base station beam may be less than a width of the first base station beam.

Abstract: Various aspects of the disclosure relate to controlling allocations for independent links. For example, a device may dynamically control the uplink/downlink allocations for different links. In some aspects, the independent links may involve a first device ( e.g. , a user equipment) communicating via different independent links with different devices ( e.g. , transmit receive points (TRPs) or sets of TRPs). At least one device may signal the uplink/downlink allocation for the different links. If the isolation between links is high, the links may use different time division duplexed (TDD) or frequency division duplexed (FDD) subframe structures. If the isolation is low or for certain types of information ( e.g. , control information), the direction of transmission for one link may be constrained to be the same as the direction of transmission for another link ( e.g. , the links may use the same TDD/FDD frame structures). Also, sounding on different links may be time division multiplexed.
