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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit an uplink grant to a UE during a first transmit opportunity. The apparatus may signal, during a second transmit opportunity, a grant trigger to the UE to trigger operations associated with the uplink grant that are uncompleted after the first transmit opportunity. The grant trigger may be associated with a set of UEs that includes the UE. The set of UEs may be a subset of the UEs having pending transmissions. The apparatus may instruct the UE regarding whether to keep or discard resources granted by the uplink grant when the UE switches to a different beam during or prior to the second transmit opportunity.

Abstract: A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UEs having different bandwidths, e.g., between a narrowband UE and a wideband eNB. A user equipment apparatus segments an uplink duration in each frame into multiple transmission units for each frequency, wherein a frame comprises an integer number of the transmission units. The apparatus transmits uplink communication based on the multiple transmission units, wherein each transmission unit comprises at least one on period and at least one off period corresponding to each of a plurality of frequencies, wherein during an on period the UE transmits uplink communication on the corresponding frequency and during an off period the UE refrains from transmitting uplink communication on the corresponding frequency. Each transmission unit may comprise multiple on periods and multiple off periods. The on/off periods may be configured by a base station or specified for each frame type.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. 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). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a system bandwidth of shared spectrum partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The base station may then transmit the configuration of the system bandwidth to a plurality of devices. A UE may receive, from a base station, a configuration of a system bandwidth of shared spectrum. The system bandwidth may be partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The UE may then communicate with the base station on at least one of the bandwidth parts.

Abstract: In an embodiment, an AP executes a CCA protocol to determine whether to begin transmission within a DMTC window of a radio frame having first and second blocks of subframes. The AP transmits a multi-subframe DRS within the DRS subframes that is scrambled in accordance with a CSI-RS scrambling rule that determines how the second DRS subframe is to be scrambled based on whether the first DRS subframe is included among the first block of subframes or the second block of subframes. At least one UE monitors the DMTC window, and descrambles the CSI-RSs in the multi-DRS subframe based on a CSI-RS descrambling rule that determines how the second DRS subframe is to be descrambled based on whether the first DRS subframe is included among the first block of subframes or the second block of subframes.

Abstract: A method, an apparatus, and a computer program for wireless communication that allows for greater scheduling flexibility of physical resources are disclosed. A UE receives information from a base station about a time division duplex (TDD) frame structure of a plurality of frames that include a plurality of subframes. The UE determines a time division duplex (TDD) frame structure for a plurality of frames, where the plurality of frames include a plurality of uplink (UL) subframes and a plurality of downlink (DL) subframes. The UE determines whether a control signaling instance is scheduled during an UL subframe of the plurality of UL subframes, wherein the control signaling instance is scheduled periodically and the control signaling includes at least one of a random access channel, an uplink control channel, a sounding reference signal (SRS), or a scheduling request (SR). The UE communicates the control signaling instance if the control signaling instance is scheduled during an UL subframe.

Abstract: Aspects directed towards a frame-based equipment (FBE) design for a multi-operator New Radio shared spectrum (NR-SS) are disclosed. In one example, at least one contention slot is monitored within a fixed frame period of an unlicensed spectrum, and a determination is performed of whether a channel reservation signal associated with a higher priority node has been detected within the at least one contention slot. For this example, the at least one contention slot is associated with a resource of a subsequent fixed frame period of the unlicensed spectrum. A determination is then made of whether to transmit communication via the resource. Here, the communication is transmitted via the resource, if the channel reservation signal is not detected, and the communication is not transmitted via the resource, if the channel reservation signal is detected.

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: Aspects of the present disclosure provide various procedures and methods for accelerated secondary cell (SCell) activation when carrier aggregation (CA) is configured. A scheduling entity receives, from a network entity, an indication of anticipated data for a user equipment (UE) in an idle mode. The scheduling entity determines supplemental wake-up information based on the carrier aggregation capability of the PCell. The scheduling entity transmits a wake-up message to the UE. The wake up message is configured to cause the UE to wake up in a CA configuration using the PCell and one or more SCells, based on the supplemental wakeup information.
